RAPTOR PHARMACEUTICAL CORP.

8.0% Convertible Senior Notes due 2019

This Note is one of a duly authorized issue of Notes of the Company, designated as its 8.0% Convertible Senior Notes due 2019 (the "Notes"), initially limited in aggregate principal amount to $60,000,00 all issued or to be issued under and pursuant to a Convertible Note Purchase Agreement dated as of July __], 2014 (the "Agreement") between the Company, the Guarantors named therein, HealthCare Royalty Partners II, L.P., HCRP Overflow Fund, L.P. and MOLAG Healthcare Royalty, LLC, each as Holder (each a "Holder" and collectively, "Holders") and the Guarantors from time to time party thereto, to which Agreement and all agreements supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Company and the Holder of the Notes.

Except as provided for in the Agreement, principal and premium on this Note shall be payable only against surrender therefor, while payments of interest on this Note shall be made, in accordance with the Agreement and subject to applicable laws and regulations, by wire transfer to such account as any Holder shall designate by written instructions received by the Company no less than fifteen (15) days prior to any applicable Interest Payment Date, which wire instruction shall continue in effect until such time as the Holder otherwise notifies the Company or such Holder no longer is the registered owner of this Note.

Interest. The Notes will bear interest at a rate of 8.0% per year. Interest on the Notes will accrue from, and including the Closing Date, or from the most recent date to which interest has been paid or duly provided for. Interest will be payable quarterly in arrears on each Interest Payment Date, beginning September 30, 2014.

Interest will be paid to the person in whose name a Note is registered at the Close of Business on the Regular Record Date (whether or not such date is a Business Day), as the case may be, immediately preceding the relevant Interest Payment Date. Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

To the extent that the payment of such interest shall be legally enforceable, upon the occurrence of and during the continuation of a Default or an Event of Default under Section 9.01(a) or 9.02(b) of the Agreement (such Default or Event of Default, a "Payment Default") (x) the interest rate borne by the Notes shall increase by, and (y) any principal of, or premium or installment of interest on, this Note which is overdue shall bear interest ("default interest") at the rate of, in each case, 1.0% per annum in excess of the rate of interest then borne by the Notes from the date of such Payment Default until cured or waived, and such default interest shall be payable in cash on each succeeding Interest Payment Date.

The Company will pay the additional interest on the Notes as provided by Article 11.

Interest will cease to accrue on a Note upon its maturity, conversion or redemption, as the case may be.

Ranking. The Notes constitute a general, senior unsubordinated and unsecured obligation of the Company and are guaranteed by certain subsidiaries of the Company.

Redemption at the Option of the Company. No sinking fund is provided for the Notes. The Notes are redeemable from time to time as a whole or in part, at any time at the option of the Company if at any time the Last Reported Sale Price of the Company's Common Stock has been greater than 175% of the Conversion Price then in effect for each Trading Day during any 30 consecutive Trading Day period. The Redemption Price for any such Optional Redemption is equal to 100% of the Principal Amount of the Notes to be redeemed and the Repayment Premium thereon, together with accrued and unpaid interest to, but excluding, the Redemption Date.

Payment of Redemption Price. If money sufficient to pay the Redemption Price of all Notes or portions thereof to be redeemed on a Redemption Date is paid to the Holder on the Redemption Date, such Notes will cease

Upon conversion, the Company will deliver shares of Common Stock as set forth in the Agreement. No fractional shares will be issued upon any conversion.

In the event of a deposit or withdrawal of an interest in this Note, including an exchange, transfer, redemption or conversion of this Note in part only, the Company shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the Agreement.

Offers to Purchase Notes. The Agreement provides that, subject to certain conditions and limitations, upon a Change of Control, the Company shall be required to make an offer to purchase all of the Notes as provided in the Agreement.

Acceleration of Maturity. Subject to certain exceptions in the Agreement, if an Event of Default shall occur and be continuing, the Principal Amount, together with the Repayment Premium plus interest through such date on all the Notes, may be declared due and payable in the manner and with the effect provided in the Agreement.

Amendments; Waiver of Past Defaults. The Agreement permits the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Agreement at any time by the Company and Holders. The Agreement also contains provisions permitting the Holders to waive compliance by the Company with certain provisions of the Agreement and certain past Defaults under the Agreement and their consequences. Any such consent or waiver by the Holders of any provision of or applicable to this Note shall be conclusive and binding upon such Holders and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

Any share of Common Stock issued upon the conversion of a Note will be issued in definitive, certificated format and will bear the Restricted Stock Legend unless the Company reasonably determines that such share of Common Stock need not bear the Restricted Stock Legend and/or need not be issued in such format.

(c) As used in this Section 3.07, the term "transfer" means any sale, pledge, hedging transaction, transfer, loan, hypothecation or other disposition whatsoever of any Restricted Note, any interest therein or any Restricted Stock.

-20-

If there shall be delivered to the Company (i) evidence to its satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by its to save it and any of its agents harmless, then, in the absence of notice to the Company that such Note has been acquired by a bona fide purchaser, the Company shall execute, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 3.09, the Company may require payment by the relevant Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith.

Every new Note issued pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 3.10 Persons Deemed Owners

. Prior to due presentment of a Note for registration of transfer to the Company or any agent of the Company, the Company and/or such agent may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of the principal of such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company nor any agent of the Company shall be affected by notice to the contrary.

Section 3.11 Transfer and Exchange

(a) Provisions Applicable to All Transfers and Exchanges.

Subject to the restrictions set forth in this Section 3.11 and elsewhere in this Agreement, Notes may be transferred or exchanged from time to time as desired, and each such transfer or exchange will be noted by the Company in the Register.

All Notes issued upon any registration of transfer or exchange in accordance with this Agreement will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Agreement as the Notes surrendered upon such registration of transfer or exchange.

No service charge will be imposed on any Holder of a Note for any exchange or registration of transfer, but the Company may require such Holder to pay a sum sufficient to cover any transfer tax, assessment or other governmental charge imposed in connection with such registration of transfer or exchange.

Unless the Company specifies otherwise, the Company will not be required to exchange or register a transfer of any Note (i) that has been surrendered for conversion or (ii) as to which Section 5.06 is applicable, in each case, except to the extent any portion of such Note is not subject to the foregoing.

Notwithstanding anything to the contrary herein, no transfer or exchange of any Note will be permitted without the prior written consent of the Company (not to be unreasonably withheld, conditioned or delayed, it being understood and agreed that the Company may withhold its consent to such a transfer or exchange if the Board of Directors determines in good faith that such transfer would not be in the best interest of the Company based on the proposed transferee's investment intention or investment history).

-21-

(b) Transfer and Exchange of Notes.

If a transfer of a Note is otherwise permitted hereunder, a Holder may transfer such Note by: (A) surrendering such Note for registration of transfer to the Company, together with any endorsements or instruments of transfer required by any of the Company; (B) delivering any documentation that the Company requires to ensure that such transfer complies with Section 3.07 and any applicable securities laws; and (C) satisfying all other requirements for such transfer set forth in this Section 3.11 and Section 3.07.

A Holder may exchange a Note for other Notes of any authorized denominations and aggregate Principal Amount equal to the aggregate Principal Amount of the Notes to be exchanged by surrendering such Notes, together with any endorsements or instruments of transfer required by the Company at any office or agency maintained by the Company for such purposes pursuant to Section 4.02. Whenever a Holder surrenders Notes for exchange, the Company, in accordance with Section 3.04, will promptly execute and deliver the Notes that such Holder is entitled to receive, bearing registration numbers not contemporaneously outstanding and any restrictive legends that such Notes are to bear under Section 3.07.

Section 3.12 Cancellation

. The Company at any time may cancel any Notes previously delivered hereunder that the Company may have acquired in any manner whatsoever. All Notes surrendered for registration of transfer, exchange, payment, purchase, repurchase, conversion (pursuant to Article 7 hereof) or cancellation will be subject to immediate cancellation by the Company. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are cancelled. The Notes so acquired, while held by or on behalf of the Company or any of its Subsidiaries, shall not entitle the Holder thereof to convert the Notes. The Company may not issue new Notes to replace Notes it has paid in full or cancelled.

At or prior to the Close of Business on the Mandatory Conversion Date, each such Holder shall satisfy the requirements set forth in clauses (i) through (v) of Section 7.02(a) with respect to the Notes subject to such Mandatory Conversion and, upon satisfaction thereof, such Notes will be converted in accordance with the provisions of this Agreement and the Notes as if, for such purpose, the Mandatory Conversion Date (or such earlier date on which a Holder completes such requirements) were the Conversion Date for the relevant number of Notes subject to such Mandatory Conversion.

Section 7.02 Conversion Procedure

(a) In order to exercise the conversion right with respect to any Notes, the Holder of any such Notes to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the Note or facsimile of the conversion notice and deliver such notice to the Company;

(ii) surrender the Note to the Company;

-28-

(iii) if required, furnish appropriate endorsements and transfer documents,

(iv) if required pursuant to Section 7.08, pay any transfer taxes or duties; and

(v) if required, pay funds equal to interest payable on the next Interest Payment Date to which the Holder is not entitled as required by Section 7.03(c).

The date on which the Holder satisfies all of the applicable requirements set forth above is the "Conversion Date."

(b) In case any Notes of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and deliver to the Holder of the Notes so surrendered, without charge to such Holder, new Notes in authorized denominations in an aggregate Principal Amount equal to the unconverted portion of the surrendered Notes.

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) on the date on which the requirements set forth above in Section 7.01(b) have been satisfied as to such Notes (or portion thereof) and the Person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become, as of the Close of Business on the relevant Conversion Date that such Holder converted the Notes, the holder of record of the shares of Common Stock represented thereby.

(c) Upon the conversion of an interest in a Note, the Holder shall make a notation on such Note as to the reduction in the Principal Amount represented thereby.

(d) Each share certificate representing Common Stock issued upon conversion of the Notes that are Restricted Notes shall bear the Restricted Stock Legend as set forth in Section 3.07.

Section 7.03 Settlement upon Conversion

(a) With respect to any conversion of Notes, if any, the Company shall, subject to the provisions of this Article 7, on the third Business Day immediately following the Conversion Date, issue and shall deliver to the converting Holder a certificate or certificates for the number of shares of Common Stock equal to, in respect of each $1,000 Principal Amount of Notes being converted, a number of shares of Common Stock equal to the Applicable Conversion Rate, rounded up to the nearest whole share of Common Stock.

(b) Upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest unless such conversion occurs between a Regular Record Date and the Interest Payment Date to which it relates and the converting Holder was the Holder on the relevant Regular Record Date.

(c) If Notes are converted after the Close of Business on a Regular Record Date for the payment of interest, Holders of such Notes at the Close of Business on such Regular Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the Close of Business on any Regular Record Date to the Open of Business on the immediately following Interest Payment Date, must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment need be made (i) for conversions following the Regular Record Date immediately preceding the Maturity Date or (ii) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(d) The Company shall not issue fractional shares upon conversion of Notes. If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion (and the number of fractional shares, if any, for which cash shall be delivered) shall be computed on the basis of the aggregate Principal Amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered.

-29-

(e) By delivery to the Holder of the full number of shares of Common Stock issuable upon conversion, the Company will be deemed to satisfy in full its obligation to pay the Principal Amount of the Notes and all accrued and unpaid interest to, but excluding, the Conversion Date. Upon conversion of the Notes, all accrued and unpaid interest to, but excluding, the Conversion Date will be deemed to be paid in full rather than canceled, extinguished or forfeited, subject to Section 7.03(c) above.

Section 7.04 Adjustment of Conversion Rate

. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs as described below, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes participate, at the same time and on the same terms as holders of shares of Common Stock, solely as a result of holding the Notes, in any of the transactions described in this Section 7.04, without having to convert their Notes, as if such Holders held a number of shares of Common Stock equal to the Applicable Conversion Rate in effect immediately prior to the adjustment thereof in respect of such transaction, multiplied by the Principal Amount of Notes held by such Holders, divided by $1,000.

(a) If the Company issues shares of Common Stock as a dividend or distribution on all or substantially all of the shares of the Common Stock, or the Company effects a share split or share combination applicable to all shares of the Common Stock, the Conversion Rate will be adjusted based on the following formula:

CR₁ = CR₀ x	OS₁
	OS₀

where,

CR0 =

the Conversion Rate in effect immediately prior to the Close of Business on the Record Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or share combination, as applicable;

CR1 =

the Conversion Rate in effect immediately after the Close of Business on such Record Date or immediately after the Open of Business on such effective date, as applicable;

OS0 =

the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record Date or immediately prior to the Open of Business on such effective date, as applicable; and

OS1 =

the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made pursuant to this Section 7.04(a) shall become effective immediately after the Close of Business on the Record Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as applicable. If any dividend, distribution, share split or share combination of the type described in this Section 7.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such share split or share combination, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or share combination had not been announced.

(b) If the Company distributes to all or substantially all holders of shares of Common Stock any rights, options or warrants entitling them for a period of not more than 30 calendar days after the date of such distribution to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, the Conversion Rate will be increased based on the following formula:

CR₁ = CR₀ x	OS₀+ X
	OS₀+ Y

where,

CR0 =

the Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;

CR1 =

the Conversion Rate in effect immediately after the Close of Business on such Record Date;

OS0 =

the number of shares of Common Stock outstanding immediately prior to the Close of Business on such Record Date;

X =

the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y =

the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the distribution of such rights, options or warrants.

The foregoing increase in the Conversion Rate shall be successively made whenever any such rights, options or warrants are distributed and shall become effective immediately after the Close of Business on the Record Date for such distribution. If such rights, options or warrants are not so distributed, the Conversion Rate will be immediately decreased to the Conversion Rate that would then be in effect if such Record Date for such distribution had not been fixed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be immediately decreased to the Conversion Rate that would then be in effect had the increase made for the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered.

In determining whether any rights, options or warrants entitle the holders of shares of Common Stock to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable upon exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its Indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company's Capital Stock or other securities (the "Distributed Property"), to all or substantially all holders of shares of Common Stock, excluding:

(i) dividends or distributions of Common Stock or rights, options or warrants of the type described under Section 7.04(a) or Section 7.04(b), as the case may be;

(ii) dividends or distributions paid exclusively in cash of the type described under Section 7.04(d); and

(iii) Spin-Offs to which the provisions set forth below in this Section 7.04(c) apply;

then the Conversion Rate will be increased based on the following formula:

CR₁ = CR₀ x	XX₀
	XX₀- FMV

where,

-30-

CR0 =

the Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such distribution;

CR1 =

the Conversion Rate in effect immediately after the Close of Business on such Record Date;

SP0 =

the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV =

the fair market value (as determined by the Board of Directors) of the Distributed Property distributed with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution.

Such increase in the Conversion Rate made pursuant to the immediately preceding paragraph shall become effective after the Close of Business on the Record Date for such distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if "FMV" (as defined above) is equal to or greater than "SP₀" (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, without having to convert its Notes, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the "FMV" (as defined above) of any distribution for purposes of this Section 7.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 7.04(c) where there has been a payment of a dividend or other distribution on all shares of the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary, or other business unit or affiliate, of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the Spin-Off) on a major U.S. or non-U.S. securities exchange (as determined by the Company) (a "Spin-Off"), the Conversion Rate will be increased based on the following formula:

CR₁ = CR₀ x	FMV₀+ MP₀
	MP₀

where,

CR0 =

the Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR1 =

the Conversion Rate in effect immediately after the end of the Valuation Period;

FMV0 =

the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of Common Stock applicable to one share of Common Stock (determined for purposes of the definition of "Last Reported Sale Price" as if such Capital Stock or similar equity interest were Common Stock) over the first ten consecutive Trading Day period after, and including, the effective date of the Spin-Off (the "Valuation Period"); and

MP0 =

the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

The increase in the Conversion Rate under the preceding paragraph will be determined as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect immediately after the Close of Business on the Record Date of the Spin-Off; provided that in respect of any conversion during the Valuation Period, references with respect to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, and including the effective date of such Spin-Off to, and including, and the Conversion Date in determining the Applicable Conversion Rate. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

-31-

(d) If any cash dividend or distribution is paid or made to all or substantially all holders of shares of Common Stock, the Conversion Rate shall be increased based on the following formula:

CR₁ = CR₀ x	XX₀
	XX₀- C

where,

CR0 =

the Conversion Rate in effect immediately prior to the Close of Business on the Record Date for such dividend or distribution;

CR1 =

the Conversion Rate in effect immediately after the Close of Business on the Record Date for such dividend or distribution;

SP0 =

C =

the amount in cash per share the Company distributes to holders of shares of Common Stock.

The increase in the Conversion Rate under this Section 7.04(d) will become effective immediately after the Close of Business on the Record Date for such dividend or distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If such dividend or distribution is not so paid or made, the Conversion Rate shall be immediately decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if "C" (as defined above) is equal to or greater than "SP₀" (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, without having to convert its Notes, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the first 10 consecutive Trading Day period immediately following, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer, the Conversion Rate will be increased based on the following formula:

CR₁ = CR₀ x	AC + (OS₁x SP₁)
	OS₀ x SP₁

where,

CR0 =

the Conversion Rate in effect immediately prior to the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender offer or exchange offer expires;

CR1 =

the Conversion Rate in effect immediately after the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender offer or exchange offer expires;

AC =

the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;

-32-

OS0 =

the number of shares of Common Stock outstanding immediately prior to the date such tender offer or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer of exchange offer);

OS1 =

the number of shares of Common Stock outstanding immediately after the date such tender offer or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender offer or exchange offer); and

SP1 =

the average of the Last Reported Sale Prices of Common Stock over the first 10 consecutive Trading Day period immediately following, and including, on the Trading Day next succeeding the date such tender offer or exchange offer expires.

The increase in the Conversion Rate under this Section 7.04(e) shall occur at the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender offer or exchange offer expires but will be given effect immediately after the Close of Business on the date such tender offer or exchange offer expires; provided that in respect of any conversion within the first 10 consecutive Trading Day period immediately following, and including, the date any such tender offer or exchange offer expires, references to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the date such tender offer or exchange offer expires to, and including, the Conversion Date in determining the Applicable Conversion Rate. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate (other than, for the avoidance of doubt, a reversal or reduction of such an adjustment as provided herein).

If the Company is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Company is ultimately prevented by applicable law from effecting all or any portion of such purchases or all such purchases are rescinded, the Conversion Rate shall immediately be readjusted to the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that had been effected.

(f) [RESERVED]

(g) In addition to those Conversion Rate adjustments required by Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) and 7.04(e), and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Market (including Market Rule 5635) and, if applicable, any securities exchange on which the Company's securities are then listed, the Company from time to time (i) may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company's best interest and (ii) may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of shares of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event.

(h) The Conversion Rate will not be adjusted, among other things:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company's securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the entry into any share repurchase program by the Company, including any accelerated share repurchase transaction or other share repurchase transaction effected through the use of derivatives;

(iii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee or director benefit plan or program of the Company, or assumed by the Company, or any of the Company's Subsidiaries;

-33-

(iv) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (iii) above and outstanding as of the date the Notes were first issued, except as set forth in Section 7.10;

(v) for a change in the par value of the Common Stock; or

(vi) for accrued and unpaid interest, if any, on the Notes.

(i) Adjustments to the Conversion Rate under this Article 7 shall be calculated to the nearest cent or to the nearest one-ten thousandth (1/10,000th) of a share of Common Stock. No adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at least 1% in the Applicable Conversion Rate. Any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, upon any conversion of the Notes (solely with respect to the Notes to be converted), the Company shall give effect to all adjustments that Company otherwise has deferred pursuant to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment.

(j) After any adjustment to the Conversion Rate pursuant hereto, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment became effective and shall mail by overnight mail such notice of such adjustment of the Conversion Rate to each Holder at such Holder's latest address appearing on the list of Holders provided for in Section 3.06, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(k) In any case in which this Section 7.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event issuing to the Holder of any Notes converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment.

(l) For purposes of this Section 7.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 7.05 Effect of Reclassification, Consolidation, Merger or Sale

. In the case of (i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination, any stock dividends or any change in par value or to no par value or from no par value to a par value), (ii) any consolidation, merger or combination involving the Company, (iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety, or (iv) any statutory share exchange, in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a "Merger Event"), then, at the effective time of the Merger Event, the Company shall execute, and the Holder shall counter-sign, a supplemental agreement permitted under Section 14.01 providing for the right to convert each $1,000 Principal Amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the "Reference Property") upon such Merger Event. If such Merger Event causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), the Reference Property into which the Notes will be convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of shares of Common Stock that affirmatively make such an election. The Company shall notify Holders of the Notes of such weighted average as soon as practicable after such determination is made.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 7.05. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into shares of Common Stock as set forth in Section 7.01 and Section 7.02 prior to the effective date of such Merger Event.

-34-

Section 7.06 Adjustments of Prices

. Whenever any provision of this Agreement requires a calculation of the Last Reported Sale Prices over a span of multiple days, the Company may make adjustments determined by the Company or its agents to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Record Date, effective date or expiration date, as the case may be, of the event occurs, at any time during the period during which such prices are to be calculated.

Section 7.07 [Reserved]

Section 7.08 Taxes on Shares Issued

. Any issue of share certificates on conversions of Notes shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes or duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of shares in any name other than that of the Holder of any Notes converted, and, in addition to any other requirements or conditions set forth herein, the Company shall not be required to issue or deliver any such share certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 7.09 Reservation of Shares

. The Company shall at all times provide, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion (assuming that, at the time of the computation of such number of shares or securities, all such Notes would be held by a single Holder).

Section 7.10 Shareholder Rights Plan

. Each share of Common Stock issued upon conversion of Notes pursuant to this Article 7 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the shares of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any current or subsequent shareholder rights agreement adopted by the Company, as any such agreement may be amended from time to time. Notwithstanding the foregoing, if prior to any conversion such rights have separated from the Common Stock in accordance with the provisions of the applicable shareholder rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed, to all holders of the Common Stock, Distributed Property as described in Section 7.03(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 7.11 Company Determination Final

. Any determination that the Company or its Board of Directors contemplated pursuant to this Article 7 shall be conclusive if made in good faith and in accordance with the provisions of this Article 7, absent manifest error.

It will not offer, sell, pledge, hedge or otherwise transfer any Notes or shares of Common Stock issuable upon conversion thereof except in a transaction that complies with the Securities Act.

Certain Restrictions on Transfer.

Each Holder also agrees not to trade in securities of the Company while such Holder is in possession of material, non-public information in a manner that would violate the U.S. federal securities laws.

Section 9.02 Acceleration of Maturity: Waiver of Past Defaults and Rescission

(a) If an Event of Default (other than those specified in Section 9.01(i) and 9.01(j) involving the Company) occurs and is continuing, then and in every such case the Holders of at least a majority in the aggregate Principal Amount of the outstanding Notes may declare 100% of the Principal Amount plus the Repayment Premium plus accrued and unpaid interest on all the outstanding Notes to be due and payable immediately, by a notice in writing to the Company (and to the other Holders if given by any Holder), and upon any such declaration such Principal Amount plus accrued and unpaid interest shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 9.01(i) or Section 9.01(j) with respect to the Company (but not with respect to any Subsidiary of the Company or any group of Subsidiaries of the Company that, in the aggregate, would constitute a Subsidiary of the Company), 100% of the Principal Amount plus accrued and unpaid interest on all outstanding Notes will automatically become due and payable without any declaration or other act on the part of any Holder.

(b) The Holders of a majority in aggregate Principal Amount of the outstanding Notes, by written notice to the Company and each other Holder, may (x) waive any past Default and its consequences and (y) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained, rescind any such acceleration with respect to the Notes and its consequences, except, in each case, with respect to a Default described in Section 9.01(a), Section 9.01(b) or Section 9.01(c), or in respect of a covenant or provision hereof which under Article 14 cannot be modified or amended without the consent of the Holder of each outstanding Note affected, if:

(i) such rescission will not conflict with any judgment or decree of a court of competent jurisdiction; and

-40-

(ii) all existing Events of Default have been cured or waived.

Upon any such waiver, the Default which has been waived shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured, for every other purpose of the Agreement; but not such waiver shall extend to any subsequent or other Default or impair any right consequent.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 9.03 [Reserved]

Section 9.04 Unconditional Right of Holders to Receive Payment

. Notwithstanding any other provision of this Agreement, the right of any Holder to receive payment of the Principal Amount (including the Redemption Price or interest in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes, any Redemption Date or otherwise, as applicable), any accrued and unpaid interest and to convert the Notes in accordance with Article 7, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected without the consent of such Holder.

Section 9.05 Restoration of Rights and Remedies

. If any Holder has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding, the Company and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Holders shall continue as though no such proceeding had been instituted.

Section 9.06 Rights and Remedies Cumulative

. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 3.07, no right or remedy herein conferred upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 9.07 Delay or Omission Not Waiver

. No delay or omission of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Holders.

Section 9.08 Control by Holders

. The Holders of a majority in aggregate Principal Amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Holders.

Section 9.09 Undertaking for Costs

. In any suit for the enforcement of any right or remedy under this Agreement in respect of the Notes, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney's fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section 9.09 shall not apply to any suit instituted by the Company or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount on any Note on or after the Maturity Date of such Note.

REGISTRATION RIGHTS

Section 11.01 Exercise of Demand

. At any time after the date ninety (90) days immediately following the Closing Date, a Holder or Holders (each, a "Requesting Holder") may deliver a written request to the Company in accordance with Section 15.02 (a "Demand") that the Company effect a registration (a "Demand Registration") with respect to the Registrable Securities under the Securities Act to cover a registered sale of such Registrable Securities for cash by such Holder; provided, however, that the Holders shall not make more than one (1) Demand in the aggregate per calendar quarter. Such Demand shall specify the number of Registrable Securities such Requesting Holder intends to include in such registration and the methods by which such Requesting Holder intends to sell or dispose of such Registrable Securities (including whether such Requesting Holder intends to distribute the Registrable Securities by means of an underwritten offering). Reasonably promptly after receipt of such Demand, the Company shall, subject to the terms and conditions of this Article 11, use its reasonable efforts to effect such registration (including by using reasonable efforts to file a Registration Statement (and executing an undertaking to file any amendments thereto) covering the Registrable Securities so requested to be registered (subject to "Blackout Periods" determined by the Board of Directors in good faith as and to the extent provided in Section 11.05), using its reasonable efforts to cause such filed Registration Statement to become effective promptly, and to qualify such Registrable Securities under applicable blue sky or other securities laws of any state of the United States of America to the extent set forth herein and complying with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution in an underwritten offering of all or such portion of such Registrable Securities as are specified in such request; provided, however, that the Company shall not be obligated to take any action to effect, or keep effective, any such registration, qualification or compliance pursuant to this Section 11.01 if there is a currently effective Registration Statement on Form S-3 pursuant to Section 11.02 below and the Company has taken all actions necessary to effect a registration of all Requesting Holders' Registrable Securities pursuant to Section 11.02 below.

In addition, in the event a Holder or Holders holds more than 500,000 shares of Common Stock issued upon conversion of the Notes, which shares no longer meet the definition of Registrable Securities solely due to clause (b) or clause (c) of such definition, then such Holder or Holders shall have the right to make up to three (3) additional Demands in the aggregate for a registration statement with respect to an underwritten offering of such shares of Common Stock (notwithstanding that such shares do not meet such definition); provided that any such Demand shall be for at least 500,000 of such shares of Common Stock and the Company shall have the rights with respect to any such underwritten offering set forth in Section 11.03.

-42-

Section 11.02 Shelf Registration

. The Company shall, reasonably promptly after the Closing Date, file a Registration Statement for a delayed or continuous offering pursuant to Rule 415 under the Securities Act (or any successor rule or regulation thereto) (together with the prospectus included therein, all amendments and supplements thereto and all exhibits and materials incorporated by reference therein, the "Shelf Registration Statement") with respect to the resale of the Registrable Securities and will use reasonable efforts to cause such Shelf Registration Statement to be declared effective by the SEC as promptly as reasonably practicable after such filing (a "Shelf Registration"). Each Shelf Registration Statement filed in connection with a Shelf Registration shall cover all of the Registrable Securities. The Company will use reasonable efforts to keep such Shelf Registration Statement (A) continuously effective, supplemented and amended (subject to "Blackout Periods" determined by the Board of Directors in good faith as and to the extent provided in Section 11.05) and (B) available for resales of the Registrable Securities by the Holders (subject to such "Blackout Periods"); provided, however, that in the event that Form S−3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall undertake to register the Registrable Securities on Form S−3 as soon as such form is available, provided that the Company shall maintain the effectiveness of any Registration Statement then in effect until such time as a Registration Statement on Form S−3 covering the Registrable Securities has been declared effective by the Commission.

Section 11.03 Company's Right to Participate in Certain Offerings; Underwriting

. In connection with any Demand Registration, if the Demand relating thereto includes more than 500,000 Registrable Securities, then (i) at the Company's option, the proposed offering relating thereto may be an underwritten offering, with the lead managing underwriter for such offering to be mutually agreed by the Requesting Holder and the Company, and (ii) the Company may include up to a like number of shares of Common Stock as were requested to be included in such registration by the Requesting Holder. In connection with any underwritten offering under a Shelf Registration, the Holders, in consultation with the Company, shall be entitled to select the lead managing underwriter for any underwriting of Registrable Securities. In any underwritten offering covered by this Article 11, the Company shall use reasonable efforts to enter into any reasonable agreement requested by such lead managing underwriter in connection with the offering, including, but not limited to, an underwriting agreement in customary form with such lead managing underwriter; provided, however, that in no event shall the Company be required to include shares of Common Stock or any other securities for its own account in such offering.

Section 11.04 No Derivatives.For the avoidance of doubt and notwithstanding anything to the contrary herein, each Holder acknowledges and agrees that the transactions intended to be covered by the registration obligations in this Article 11 will only cover the resale of such Registrable Securities for cash by the Holder thereof and not include (without limiting the generality of any other limitations on such transactions elsewhere herein), sales of Registrable Securities by transferees, pledgees or other successors in interest to a Requesting Holder; sales or loans by a Requesting Holder or third parties pursuant to derivative or other transactions in connection with which Registrable Securities are to be delivered; or the sale or delivery of Registrable Securities in connection with the sale by the Requesting Holder or a third party of securities exchangeable for or convertible into Registrable Securities or upon exchange or conversion of such securities.

Section 11.05 Obligations of the Company

. At such time as the Company is obligated to file a Registration Statement with the Commission pursuant to this Article 11, the Company shall also be obligated to use reasonable efforts to take the following actions:

reasonably promptly prepare and file with the Commission such amendments and supplements to any Registration Statement filed pursuant to Section 11.01 or Section 11.02 and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective until such time as the securities of the Holders subject to such Registration Statement cease to be Registrable Securities; provided that, for the avoidance of doubt, in no event shall the Company have any obligation to keep such Registration Statement effective after such time as all of the securities of such Holders subject to such Registration Statement have been sold pursuant to the Registration Statement or Rule 144 or any other available exemption from the registration requirements of the Securities Act;

before filing a Registration Statement or prospectus or any amendments or supplements thereto (excluding documents to be incorporated by reference therein, except in the case of the preparation of the initial Registration Statement), a reasonable period of time before filing, furnish to legal counsel for each Holder participating in such offering and the underwriters, if any, copies of all such documents in sub-

-43-

stantially the form proposed to be filed (including documents incorporated therein by reference), to enable such Holders and the underwriters, if any, to review such documents prior to the filing thereof, and the Company shall make such reasonable changes thereto (including changes to, or the filing of amendments reflecting such changes to, documents incorporated by reference) as may be reasonably requested by such Holders and the managing underwriter or underwriters, if any;

cooperate with the Holders participating in such offering and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates (not bearing any legends) representing Registrable Securities to be sold after receiving written representations and covenants from each such Holder in form reasonably satisfactory to the Company that the Registrable Securities represented by the certificates so delivered by such Holder have been sold, and will be transferred, in accordance with the Registration Statement, and enable such Registrable Securities to be in such denominations and registered in such names as the underwriter(s), if any, or such Holders may request reasonably promptly following such sale;

register and qualify the securities covered by such Registration Statement under "blue sky" laws of such jurisdictions as shall be reasonably requested by the underwriters and Holders (and to maintain such registrations and qualifications effective for the applicable period of time set forth in Section 11.05(a) above), and to do any and all other acts and things that may be necessary or advisable to enable the underwriters and such Holders to consummate the disposition in such jurisdictions of such shares (provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not be required but for this Section 11.05(e), (ii) subject itself to taxation in any such jurisdiction, or (iii) file any general consent to service of process in any such jurisdiction));

notify each Holder of Registrable Securities covered by such Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use reasonable efforts promptly to amend or supplement such prospectus or Registration Statement or any document incorporated or deemed to be incorporated therein by reference, or file any other required document, as applicable, in order to cause such prospectus to not include 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 not misleading in the light of the circumstances then existing;

notify each Holder of Registrable Securities covered by such Registration Statement and the underwriters: (i) when the prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iv) if at any time any of the representations or warranties of the Company contemplated by paragraph (j) below cease to be true and correct; and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

-44-

cause all Registrable Securities sold pursuant to a Registration Statement to be listed on The NASDAQ Global Market;

make such representations and warranties to the participating Holders and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings by selling shareholders of comparable size and confirm the accuracy of the same if and when requested, and matters relating to the compliance of the Registration Statement and the prospectus with the Securities Act;

bear all expenses in connection with the procedures in Section 11.01, Section 11.02 and this Section 11.07 and the registration of the Registrable Securities pursuant to the Registration Statement; provided, however, that each Holder shall bear the cost of Selling Expenses with respect to such Holder's Registrable Securities, if any, in connection with the offering of the Registrable Securities pursuant to the Registration Statement and each Holders and any other Person participating in such offering shall bear all such specified Selling Expenses pro rata among each other on the basis of the number of Registrable Securities which have been registered;

if requested by any underwriter for purposes of a disposition of Registrable Securities, provide such underwriter, its attorneys and agents the opportunity to conduct a reasonable due diligence investigation with respect to the Company.

Section 11.06 Black-Out Periods

. Notwithstanding anything to the contrary herein, the Company may delay the disclosure 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, in the best interest of the Company and, in the opinion of counsel to the Company, otherwise required (a "Black-Out Period"); provided, that the Company shall promptly notify the Holders in writing of the existence of material, non−public information giving rise to a Black-Out Period (provided that in each notice the Company will not be required to disclose the content of such material, non−public information to the Holders) and the date on which the Black-Out Period will begin, and (ii) notify the Holders in writing of the date on which the Black-Out Period ends; and, provided further, that the Black-Out Periods shall not exceed an aggregate of 20 Trading Days during any three hundred sixty five (365) day period and the first day of any Black-Out Period must be at least 30 days after the last day of any prior Black-Out Period (each, an "Allowable Black-Out Period"). For purposes of determining the length of a Black-Out Period above, the Black-Out Period shall begin on and include the date the Holders receive the notice referred to in clause (i) and shall end on and include the later of the date the Holders receive the notice referred to in clause (ii) and the date referred to in such notice. The provisions of Section 11.05(l) hereof shall not be applicable during the period of any Allowable Black-Out Period. Upon expiration of the Black-Out Period, the Company shall again be bound by Section 11.05(g) 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 shares of Common Stock to a transferee of any Holder in accordance with the terms of this Agreement in connection with any sale of Registrable Securities with respect to which a Holder has entered into a contract for sale, and delivered a copy of the prospectus included as part of the applicable Registration Statement (unless an exemption from such prospectus delivery requirement exists), prior to the Holder's receipt of the notice of a Black-Out Period and for which the Holder has not yet settled.

Section 11.07 Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement or Failure to Timely Convert

(a) Notwithstanding anything herein to the contrary, if (a) 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 (i) not filed with the Commission (a "Filing Failure") on or before the 30^th day following the Closing Date (the "Filing Deadline") or (ii) not declared effective by the Commission

-45-

(an "Effectiveness Failure") on or before on or before the 90^th day following the Closing Date (the "Effectiveness Deadline"), (b) on any day after the Effective Date of a Registration Statement, 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) 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 shares of Common Stock) (a "Maintenance Failure") or (c) the Company fails to deliver via DWAC or issue a certificate to a Holder for the number of shares of Common Stock to which such Holder is entitled upon conversion of any amount of Notes on or prior to the date which is three (3) Trading Days after the Conversion Date (a "Conversion 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 underlying shares of Common Stock, additional interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum (which rate shall be increased by an additional 0.50% per annum for each subsequent 90-day period that such additional interest continues to accrue, provided that the rate at which such additional interest continues to accrue may in no event exceed 1.0% per annum) until such Filing Failure, Effectiveness Failure, Maintenance Failure or Conversion Failure, as the case may be, is cured. The payments to which a holder shall be entitled pursuant to this Section 11.07 are referred to herein as "Delay Payments." Any Delay Payments will be payable in the same form, on the same dates and to the same persons as the Company makes other interest payments on the Notes; provided, that any Delay Payments in respect of a Conversion Failure shall be payable only to the Holder or Holders whose shares have not been delivered. In the event the Company fails to make Delay Payments in a timely manner, such Delay Payments shall bear interest at the rate of one percent (1.0%) per month (prorated for partial months) until paid in full.

Section 11.08 Obligations of Holders

(a) Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it or an exemption therefrom in connection with sale of Registrable Securities pursuant to the Registration Statement.

(b) Each Holder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in Section 11.06(f) or Section 11.06(g)(iii), such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or prospectus until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 11.06(f), or until it is advised in writing by the Company that the use of the applicable prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such prospectus.

(c) Each Holder shall furnish to the Company materially complete and accurate information regarding such Holder, the Registrable Securities and other securities of the Company held by it and the distribution proposed by such Holder as shall be required by applicable law or requested by the underwriter(s) to effect the registration of their Registrable Securities.

Section 11.09 Indemnification

(a) To the extent permitted by law, the Company will indemnify each Holder, each of its officers, directors, partners and agents, and each Person controlling such Holder (within the meaning of Section 15 of the Securities Act), with respect to any registration, qualification, compliance or sale which has been effected pursuant to this Article 11, and each underwriter, if any, and each Person who controls any underwriter (within the meaning of Section 15 of the Securities Act), against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance or sale, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any such prospectus, in the light of the circumstances in which they were made) not misleading, or any violation (or alleged violation) by the Company of (i) the Securities Act, the Exchange Act or any rule or regulation promulgated thereunder

or (ii) the securities or similar laws of any state or other jurisdiction in which Registrable Securities are sold in an underwritten offering, and the Company will reimburse or pay for the account of each Holder, each of its officers, directors, partners and agents, each Person controlling such Holder, each such underwriter and each Person who controls any such underwriter, for any legal and any other expenses reasonably incurred (as and when incurred) in connection with investigating, preparing the defense of or defending any such claim, loss, damage, liability or action; provided that, notwithstanding the foregoing, the Company will not be liable hereunder in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with information furnished to the Company by such Holder, such controlling person or underwriter.

(b) To the extent permitted by law, each Holder will, if securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of the Company's securities covered by such a Registration Statement, each Person who controls the Company or such underwriter (within the meaning of Section 15 of the Securities Act), and any other Person participating in such registration, each of its officers and directors and each Person controlling (within the meaning of Section 15 of the Securities Act) such Person participating in such registration, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, prospectus, offering circular or other document incident to any such registration, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any such prospectus, in the light of the circumstances in which they were made) not misleading and will reimburse or pay for the account of the Company, such Persons, such directors, officers, Persons, underwriters or control Persons for any legal or any other expenses reasonably incurred (as and when incurred) in connection with investigating, preparing the defense of or defending any such claim, loss, damage, liability or action; provided that in no event shall any Holder have any liability hereunder in any such case except to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with information furnished to the Company by such Holder.

(c) Each Person entitled to indemnification under this Section 11.09 (the "Indemnified Party") shall give notice to the Person required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (which approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party's expense; provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent that the failure to give such notice is materially prejudicial to an Indemnifying Party's ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(d) The obligations of the Company and each Holder under this Section 11.09 shall survive the completion of any offering of Registrable Securities in a Registration Statement pursuant to this Agreement.

(e) If a claim for indemnification under Section 11.09(a) or Section 11.09(b) is available by its terms but is held by a court of competent jurisdiction to be unavailable or insufficient to hold harmless an Indemnified Party, then each Indemnifying Party in lieu of indemnifying such Indemnified Party shall contribute to the amount paid or payable by such Indemnified Party as a result of any such claim, loss, liability or action that otherwise would have been indemnified under Section 11.09(a) or Section 11.09(b), as the case may be, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the statements, omissions, actions or inactions that resulted in such claim, loss, liability or action, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party or the Indemnified Party, any action or inaction by any such Party, and the Parties'

-47-

relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission, action or inaction. The amount of such claim, loss, liability or action subject to this Section 11.09(e) shall be deemed to include any reasonable legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such claim, loss, liability or action (which shall be limited as provided in Section 11.09(c) if the Indemnifying Party has assumed the defense of any such action in accordance with the provisions thereof). Notwithstanding the foregoing in this Section 11.09(e), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Party who was not guilty of such fraudulent misrepresentation. Promptly after receipt by an Indemnified Party of written notice of the commencement or threatened commencement of any claims for which a claim for contribution may be made against an Indemnifying Party under this Section 11.09(e) and if a notice for indemnification has not been otherwise given under this Section 11.09, such Indemnified Party shall give written notice thereof in the manner set forth hereunder for a claim for indemnification to the Indemnifying Party; provided, however, that the failure to so notify the Indemnifying Party shall not relieve it of any obligation to provide contribution hereunder except to the extent that the Indemnifying Party's ability to defend such action is materially prejudiced by the failure to give such timely notice. The Parties acknowledge that determining contribution pursuant to this Section 11.09(e) by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 11.09(e) would not be just or equitable. For the avoidance of doubt, if indemnification is available under Section 11.09(a) or Section 11.09(b), the Indemnifying Parties shall indemnify each Indemnified Party to the fullest extent provided in Section 11.09(a) or Section 11.09(b) without regard to the relative fault of said Indemnifying Party or Indemnified Party or any other equitable consideration provided for in this Section 11.09(e).

Section 11.10 Effectiveness; Termination; Survival

. The provisions of this Article 11 shall survive the termination of this Agreement.

ARTICLE 12.
GUARANTEE

Section 12.01 Guarantee

. By its execution hereof, each Guarantor acknowledges and agrees that it receives substantial benefits from the Company and the issuance of the Notes and that the Guarantors are providing their Guarantee for good and valuable consideration, including, without limitation, such substantial benefits. Accordingly, subject to the provisions of this Article 12, the Guarantors hereby jointly and severally unconditionally guarantee, as a primary obligor and not as a surety, to each Holder and its successors and assigns that: (x) the principal of (including the Redemption Price), and interest on the Notes shall be duly and punctually paid in full and/or performed in accordance with the terms of this Agreement when due, whether at the Maturity Date, upon declaration of acceleration, upon redemption, upon conversion or otherwise, and interest on overdue principal, interest, and (to the extent permitted by law) interest on any interest, if any, on the Notes and (y) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity Date, by acceleration, redemption, conversion or otherwise. Furthermore, subject to the provisions of this Article 12, the Guarantors hereby jointly and severally unconditionally guarantee to each Holder and their respective successors and assigns that (z) all other obligations of the Company to the Holders hereunder or under the Notes (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the terms hereof, subject, however, in the case of clauses (x), (y) and (z) above, to the limitations set forth in Section 12.03 hereof (the obligations set forth in this Section 12.01 collectively, the "Guarantee Obligations"). The Guarantee constitutes a senior unsubordinated obligation of each Guarantor.

(a) Subject to the provisions of this Article 12, the Guarantors hereby jointly and severally agree that the Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Agreement, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of any Guarantor. Each Guarantor hereby waives and relinquishes: (a) any right to require the Holders or the Company (each, a "Benefited Party") to proceed against the Company or any other Person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party's power before proceeding against the Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or the failure of a Benefited Party to file or enforce a claim against the estate (in

-48-

administration, bankruptcy or any other proceeding) of any other Person or Persons; (c) demand, protest and notice of any kind (except as expressly required by this Agreement), including but not limited to notice of the existence, creation or incurring of any new or additional Indebtedness or obligation or of any action or non-action on the part of the Guarantor, the Company, any Benefited Party, any creditor of the Guarantor or the Company or on the part of any other Person whomsoever in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefited Party, including but not limited to an election to proceed against the Guarantor for reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any defense arising because of a Benefited Party's election, in any proceeding instituted under Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code; and (g) any defense based on any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code. Each Guarantor hereby covenants that, except as otherwise provided therein, the Guarantee shall not be discharged except by payment in full of all Guarantee Obligations, including the principal and interest on the Notes and all other costs provided for under this Agreement.

(b) The Guarantors as principal obligors and as separate and independent obligations and liabilities from their other obligations and liabilities under this Agreement jointly and severally agree to indemnify and keep indemnified each Holder in full and on demand in respect of the performance and discharge of the Guarantee Obligations (except where the Company's failure to perform or discharge the Guarantee Obligations results from such Holder's failure to comply with its obligations under the Agreement or the Company contesting any payment or part of a payment in good faith).

(c) If any Holder is required by any court or otherwise to return to either the Company or any Guarantor, any amount paid by the Company or such Guarantor to such Holder, then the Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantors jointly and severally agree that they shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. The Guarantors jointly and severally agree that, as between them, on the one hand, and the Holders, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 9 hereof for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article 9 hereof, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Guarantee.

(d) If, at any time after the date of this Agreement, a Subsidiary that was not a Guarantor on the date hereof subsequently provides the Guarantee or the Company or any of its Subsidiaries creates or acquires a new Subsidiary (other than those Subsidiaries expressly excluded from the definition of Guarantor herein), the Company will cause such Subsidiary to (i) execute a supplemental agreement, (ii) provide a notation of Guarantee pursuant to such supplemental agreement and (iii) otherwise comply with the provisions of this Article 12 including, but not limited to, endorsing and delivering a notation of Guarantee.

Section 12.02 Execution and Delivery of Guarantee

. To evidence the Guarantee set forth in Section 12.01 hereof, each Guarantor agrees that a notation of the Guarantee substantially in the form thereof included in Section 2.03 hereto shall be endorsed on each Note and that this Agreement shall be executed on behalf of each Guarantor by an officer of such Guarantor.

(a) The Guarantors jointly and severally agree that the Guarantee set forth in this Article 12 shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of the Guarantee.

(b) If any officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Note is executed on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.

(c) The delivery of any Note, after the execution thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Agreement on behalf of each Guarantor.

-49-

Section 12.03 Limitation of Guarantors' Liability; Certain Bankruptcy Events

. Each Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and each Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantors under this Article 12 shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantors, result in the Guarantee Obligations of the Guarantors under the Guarantee not constituting a fraudulent transfer or conveyance.

Section 12.04 Application of Certain Terms and Provisions to the Guarantor s

(a) For purposes of any provision of this Agreement which provides for the delivery by any Guarantor of an Officers' Certificate, the definitions of such terms in Section 1.01 hereof shall apply to such Guarantor as if references therein to the Company or Guarantors, as applicable, were references to such Guarantor.

(b) Any request, direction, order or demand which by any provision of this Agreement is to be made by the Guarantors shall be sufficient if evidenced as described in Section 15.02 hereof as if references therein to the Company were references to a Guarantor.

Section 12.05 Releases

. If, in compliance with the terms and provisions of the Notes Documents, all of the Capital Stock of any Guarantor is sold or otherwise transferred (a "Transferred Guarantor") to a Person or Persons, none of which is the Company or a Subsidiary, such Transferred Guarantor shall, upon the consummation of such sale or transfer, be automatically released from its obligations under this Agreement.

(b) Notwithstanding anything to the contrary set forth in this Agreement or any other Notes Document, the Recipient may, without the consent of the Disclosing Party, but with prior written notice when permissible to the Disclosing Party, furnish or disclose Confidential Information of the Disclosing Party to (i) the Recipient's Affiliates and their respective Representatives, actual or potential financing sources, investors or co-investors and permitted assignees, purchasers, transferees or successors-in-interest under Section 3.07, in each such case, who need to know such information in order to provide or evaluate the provision of financing to the Recipient or any of its Affiliates or to assist the Recipient in evaluating the transactions contemplated by this Agreement and the other Notes Documents or in exercising its rights and remedies and performing its obligations hereunder and thereunder and who are, prior to such furnishing or disclosure, informed of the confidentiality and non-use obligations contained in this Section 15.04 and who are bound by written or professional confidentiality and non-use obligations no less stringent than those contained in this Section 15.04; and (ii) permitted assignees, purchasers, transferees or successors-in-interest under Section 3.07, in each such case, who need to know such information in connection with such actual or potential assignment, sale or transfer, including, following any such assignment, sale or transfer, in order to exercise their rights and remedies and perform their obligations under this Agreement and the other Notes Documents and who are, prior to such furnishing or disclosure, informed of the confidentiality and non-use obligations contained in this Section 15.04 and who are bound by written or professional confidentiality and non-use obligations no less stringent than those contained in this Section 15.04.

Subject to the foregoing, the Recipient, such Affiliates or such Representatives, as the case may be, may disclose that portion (and only that portion) of the Confidential Information of the Disclosing Party that is legally required to be disclosed; provided, however, that the Recipient, such Affiliates or such Representatives, as the case may be, shall exercise reasonable efforts (at their expense) to preserve the confidentiality of the Confidential Information of the Disclosing Party, including by obtaining reliable assurance that confidential treatment will be accorded any such Confidential Information disclosed.

(b) Each party hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action proceeding arising out of or relating to this Agreement or the Notes in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

Section 15.18 Force Majeure
