(a) On May 17, 2011, NB will purchase and Radius will sell and issue to NB 64,430 shares of Radius Series A-5 Preferred Stock (the “Series A-5 Shares”), representing the quotient (rounded to the nearest whole number) obtained by dividing (x) the U.S. Dollar equivalent (determined in accordance with the provisions of the next sentence) of €371,864 by (y) US$8.142 per share (the “Series A-5 Purchase Price Per Share”). Radius shall determine the U.S. Dollar equivalent of such €371,864 using the exchange rate for buying U.S. Dollars with EUROS set forth in The Wall Street Journal(Online Edition) Market Data Center at xxxx://xxxxxx.xxx.xxx/xxx/xxxxxx/xxxx/xxxxxxxxxxx.xxxx on the Business Day that is two (2) Business Days preceding the date of the Closing. The aggregate purchase price payable by NB for the Series A-5 Shares shall be €371,864.

(b) The purchase and sale of the Series A-5 Shares to be purchased and sold pursuant to Section 2.1(a) shall take place at the offices of Xxxxxxx XxXxxxxxx LLP, One Federal Street, Boston, Massachusetts, at 10:00 a.m. local time on May 17, 2011 (which time and place are referred to as the “Closing”).

(c) At the Closing, Radius will deliver to NB a certificate registered in NB’s name representing the Series A-5 Shares, against payment of the purchase price therefor by wire transfer in accordance with Radius’s instructions;.

2.2 Reservation of Series A-5 Preferred Stock and Series A-6 Preferred Stock. Radius will, prior to the Closing, authorize: (a) the sale and issuance of the Series A-5 Shares; (b) the accrual and issuance of all of the shares of Series A-6 Convertible Preferred Stock, par value $0.01 per share (the “Series A-6 Preferred Stock”), of Radius in accordance with the provisions of this Agreement; and (c) the reservation of shares of Common Stock, par value $0.01 per share for issuance upon conversion of the Series A-5 Preferred Stock and the Series A-6 Preferred Stock (the “Conversion Shares”). The Series A-5 Preferred Stock, the Series A-6 Preferred Stock and the Common Stock have the rights, privileges, preferences and restrictions set forth in the Fourth Amended and Restated Certificate of Incorporation of Radius, including those summarized in the Term Sheet in the form attached hereto as Attachment A, with such changes and additional provisions as may be made by Radius after the date hereof in connection with the negotiation by Radius of the closing documents for the Series A-1 Financing with prospective investors in the Series A-1 Financing (the “Restated Certificate”). The Series A-5 Preferred Stock and the Series A-6 Preferred Stock shall have the same right, privileges, preferences and restrictions except that the Series A-6 Preferred Stock shall not be entitled to accrue any shares of capital stock of Radius, whether as a stock dividend or otherwise, pursuant to, and in accordance with, the terms and conditions of this Agreement.

3. BONUS SHARES

3.1 Calculation of Bonus Shares; Issuance of Bonus Shares. (a) Subject to the terms and conditions of this Agreement (including the limitations set forth in Section 3.4), the holders of shares of Series A-5 Preferred Stock shall be entitled to receive stock dividends, payable in shares of Series A-6 Preferred Stock in accordance with the provisions of this Section 3.1, having an aggregate value (determined as provided in this Section 3.1) of up €[*] as calculated on the date that such stock dividends accrue in accordance with this Section 3.1. Subject to the terms and conditions of this Agreement (including the limitations set forth in Section 3.4), on the last Business Day of each calendar quarter (each, an “Accrual Date”), beginning with the calendar quarter during which the first subject is enrolled in the clinical study that is the subject of Work Statement NB-1, each outstanding share of Series A-5 Preferred Stock shall accrue, as a stock dividend, a number of shares of Series A-6 Preferred Stock having a value (determined as provided further below in this Section 3.1) equal to (x) €36,814,531 minus the aggregate value of any prior stock dividends that accrue pursuant to this Section 3.1(a) (with such aggregate value of such prior stock dividends being determined as of the applicable prior Accrual Date) divided by (y) the number of calendar quarters the Project Committee has determined it will take to complete the clinical study that is the subject of Work Statement NB-1 and lock the study database and transfer the study database to Radius in its then most recent determination delivered in accordance with Section 3.1(b).

(b) When calculating the aggregate number of Bonus Shares accruing in each calendar quarter, Radius shall convert the portion of €36,814,531 to accrue in such calendar quarter into U.S. Dollars using the simple average of the exchange rate for buying U.S. Dollars with EUROS set forth in The Wall Street Journal(Online Edition) Market Data Center at xxxx://xxxxxx.xxx.xxx/xxx/xxxxxx/xxxx/xxxxxxxxxxx.xxxx for all Mondays’ in such calendar quarter. Radius shall then calculate the aggregate number of Bonus Shares accrued in such calendar quarter by dividing (x) the U.S. Dollar equivalent (determined in accordance with the provisions set forth in the preceding sentence) of the Applicable Quarterly Amount, by (y) the Fair Market Value as of the applicable Accrual Date, and rounding down the resulting quotient to the nearest whole number. In the event that the Bonus Shares that accrue in any calendar quarter are in the form of stock dividends accruing on the shares of Series A-5 Preferred Stock that are outstanding on the Accrual Date applicable to such calendar quarter, the number of Bonus Shares accruing in such calendar quarter with respect to each share of Series A-5 Preferred Stock outstanding on the applicable Accrual Date shall be equal to the quotient (rounded down to the nearest whole number) obtained by dividing (i) the number of Bonus Shares that accrue on such applicable Accrual Date by (ii) the total number of shares of Series A-5 Preferred Stock issued and outstanding as of such applicable Accrual Date.

(c) Radius and NB, acting through the Project Committee in accordance with Section 3 of the CTS Agreement, will evaluate the study timeline and update the completion date for the clinical study that is the subject of Work Statement NB-1 set forth in Work Statement NB-1 to account for delays or accelerations in the performance of the clinical study that is the subject of Work Statement NB-1. Not later than [*] ([*]) calendar days before the end of each calendar quarter, the Project Committee will provide Radius with a written update detailing the number of calendar quarters that the Project Committee determines it will take to complete the clinical study that is the subject of Work Statement NB-1 and lock the study database and transfer the study database to Radius. Based upon such written update provided by the Project Committee, Radius shall calculate, on the applicable Accrual Date, the number of Bonus Shares that accrue on such applicable Accrual Date in accordance with the provisions of Section 3.1(a). Within [*] ([*]) days following the end of each calendar quarter, Radius shall provide NB with a written report (each, a “Bonus Shares Report”) setting forth the calculation of the number of Bonus Shares that accrued in such calendar quarter in accordance with Section 3.1(a) and the aggregate Bonus Shares accrued as of the end of such calendar quarter. Such Bonus Shares Report shall be certified by the Chief Financial Officer (or equivalent financial and accounting officer) of Radius to be correct to the best of Radius’ knowledge and information.

(d) The Bonus Shares Report as prepared by Radius shall be conclusive and binding on NB unless NB shall notify Radius in writing within [*] ([*]) days after receipt thereof that, in the opinion of NB, the number of Bonus Shares set forth on the Bonus Shares Report has not been calculated correctly. Such notice (the “Dispute Notice”) shall set forth in reasonable detail each item and amount with which NB disagrees and the basis for such disagreement. Radius and NB shall attempt to resolve such dispute and agree in writing upon the final content of the Bonus Shares Report and the final calculation of the number of Bonus Shares accrued in the period. If the

parties cannot so agree within [*] ([*]) Business Days after the delivery by NB to Radius of the Dispute Notice, then either Radius or NB may submit such dispute to an independent arbitrator for determination (an “Arbitration”) in accordance with the terms set forth in Section 3.1(e)-(g).

(e) Any request for Arbitration shall be made in writing to an independent accounting firm of recognized national standing to be mutually selected by Radius and NB, which firm shall not be an auditing firm for either party and shall not have provided material services to either party during the [*] ([*]) year period prior to the date of Arbitration initiation. The firm to which such request is made shall, upon agreeing in writing to determine the number of Bonus Shares that have accrued in such quarterly period in accordance with the terms of this Section 3.1, be the “Independent Accounting Firm”, as that term is used in this Section 3.1. If the parties are not able to agree within [*] ([*]) Business Days after the receipt by a party of the arbitration request, the New York Office of the American Arbitration Association shall be responsible for selecting an Independent Accounting Firm within [*] ([*]) Business Days of being approached by a party.

(f) The Arbitration shall be conducted under the auspices of the Independent Accounting Firm and shall be conducted in accordance with the then current expedited procedures applicable to the then current Commercial Arbitration Rules and Supplementary Procedures for Large Complex Disputes (“Rules”) of the American Arbitration Association, as such Rules and procedures may be modified by this Section 3.1(f). The Independent Accounting Firm shall, within [*] ([*]) Business Days of its agreement to determine the number of Bonus Shares that have accrued in such quarterly period, provide to Radius and NB the name of its partner who will serve as the individual responsible for conducting the Arbitration (the “Arbitrator”). Within [*] ([*]) Business Days after the designation of the Arbitrator, the parties shall each simultaneously submit to the Arbitrator and one another a written statement of their respective positions on such disagreement. Each party shall have [*] ([*]) Business Days from receipt of the other party’s submission to submit to the Arbitrator and the other party a written response thereto. The Arbitrator shall have the right to meet with the parties, either alone or together, as necessary to make a determination. The Arbitrator shall conduct an Arbitration to determine the number of Bonus Shares that have accrued in such quarterly period. The Arbitrator shall make such determination subsequent to conducting the Arbitration and shall set forth such determination in a written ruling, which ruling shall be rendered within [*] ([*]) days of the selection date of the Arbitrator and shall be delivered to Radius and NB.

(g) The locale of all hearings conducted by the Arbitrator in connection with the Arbitration shall be the New York office of the Independent Accounting Firm. The ruling of the Arbitrator shall be final, binding, and conclusive on Radius and NB; shall have the legal effect of an arbitral award; and shall be subject only to the judicial review permitted by the Federal Arbitration Act. Judgment on the ruling of the Arbitrator may be entered and enforced in any court having jurisdiction over the parties or their assets. The fees and disbursements of the Independent Accounting Firm shall be allocated and payable between Radius on the one hand and NB on the other hand in the same proportion that (i) the additional number of Bonus Shares that have been determined by the Arbitrator to have accrued in such period bears to (ii) the additional number of Bonus Shares that NB initially claimed in its Dispute Notice accrued in such period. If a party fails to proceed with Arbitration, unsuccessfully challenges the arbitration award, or fails to comply with the arbitration award, the other party is entitled to costs, including reasonable attorneys’ fees, for having to compel arbitration or defend or enforce the award. Except as otherwise required by law, the parties and the Arbitrator and Independent Accounting Firm will maintain as confidential all information or documents obtained during the arbitration process, including the resolution of the dispute. The parties knowingly and voluntarily waive their rights to have their dispute tried and adjudicated by a judge and jury; provided that nothing in this Section 3.1(g) will prevent a party from resorting to judicial proceedings if: (1) interim relief from a court is necessary to prevent serious and irreparable injury to such party; or (2) litigation is required to be filed prior to the running of the applicable statute of limitations. The use of any alternative dispute resolution procedure will not be construed under the doctrine of latches, waiver or estoppel to affect adversely the rights of either party. The parties shall use the procedure set forth in Section 3.1(e)-(g) for any dispute concerning calculation of Bonus Shares; any other disputes concerning this Agreement and the transactions contemplated hereby shall be resolved in accordance with Section 8.12.

* Confidential Treatment Requested by the Registrant. Redacted Potion Filed Separately with the Commission.

(h) Bonus Shares that accrue pursuant to Section 3.1(a) shall be subject to proportionate and equitable adjustment upon any stock splits, stock dividends, reverse stock splits, recapitalizations, mergers and other similar events involving or affecting the Series A-5 Preferred Stock.

(i) Bonus Shares that accrue pursuant to Section 3.1(a) shall be payable, when, as and if declared or paid by the Board of Directors of Radius. The Board of Directors of Radius shall be required to declare and pay such Bonus Shares accrued pursuant to Section 3.1(a) hereof: (i) upon the request of the holder(s) of a majority of the shares of common stock or other capital stock issued or issuable in respect of Series A-5 Preferred Stock or (ii) on any Event of Sale.

(j) The stock dividend feature of Section 3.1(a), as well as all other forms of accrual of Bonus Shares under this Agreement (including, without limitation, any contractual accrual of Bonus Shares pursuant to the second paragraph of Section 3.1(k) below or pursuant to Section 3.1(l) below) shall terminate upon an Event of Sale. Upon an Event of Sale, the Person that becomes the successor of Radius as a result of such Event of Sale shall, in lieu of accruing Bonus Shares pursuant to this Agreement, make cash payments to NB for the services to be rendered pursuant to Work Statement NB-1.

(k) The stock dividend feature of Section 3.1(a) hereof shall also terminate upon the occurrence of any event that is not an Event of Sale if such event causes all outstanding shares of Series A-5 Preferred Stock of Radius to convert into, or be exchanged for, common stock of Radius or any other Person (including a Shell Company Successor) or any other class or series of capital stock of Radius or any other Person (including a Shell Company Successor); provided, however, that such stock dividend feature shall not terminate if such event that is not an Event of Sale consists of an acquisition of Radius, directly or indirectly, by such Shell Company Successor pursuant to which all shares of each of Series A-5 Preferred Stock and Series A-6 Preferred Stock of Radius shall convert into, or be exchanged for, shares of a series of preferred stock of the Shell Company Successor that has adopted and incorporated substantially the same terms provided under this Agreement with respect to the Series A-5 Preferred Stock or the Series A-6 Preferred Stock, as the case may be, of Radius, in which case such stock dividend feature shall be applicable to such series of preferred stock of the Shell Company Successor.

Upon termination of the stock dividend feature pursuant to this Section 3.1(k) in connection with an event that is not an Event of Sale: (1) all accrued Bonus Shares not yet issued or paid shall automatically convert into the right to receive a distribution of that number of accrued but not yet issued or paid shares of such common stock or such other class or series of capital stock that a holder of such accrued but not yet issued Bonus Shares would have been entitled to receive with respect to such Bonus Shares if such holder had claimed such Bonus Shares using the procedure described in Section 3.1(i)(i) and been the holder of record of such Bonus Shares immediately prior to the occurrence of such event; and (2) all Bonus Shares, if any, that would have accrued pursuant to Section 3.1(a) at any time after the occurrence of such event if such event had not occurred, shall accrue pursuant to this clause (2) on the same terms and conditions as if such accrual had been under Section 3.1(a) hereof and be payable in shares of such common stock of Radius or any other Person (including a Shell Company Successor), as the case may be, or such other class or series of capital stock of Radius or any other Person (including a Shell Company Successor), as the case may be, in accordance with the terms of this Agreement as if such accrual had been pursuant to Section 3.1(a). For purposes of clarification, any accrual of Bonus Shares pursuant to clause (2) of this paragraph shall be a contractual accrual and not an accrued stock dividend.

(l) The stock dividend feature of Section 3.1(a) shall also terminate upon the transfer by NB of any or all of the Series A-5 Shares to any Person. Upon termination of the stock dividend feature pursuant to this Section 3.1(m), all Bonus Shares, if any, that would have accrued pursuant to Section 3.1(a) at any time after the occurrence of such transfer of Series A-5 Shares by NB if such transfer had not occurred, shall accrue pursuant to this Section 3.1(m) for the exclusive benefit of NB (and not the Person to whom such Series A-5 Shares were transferred) on the same terms and conditions as if such accrual had been under Section 3.1(a) hereof and be payable in shares of Series A-6 Preferred Stock subject to, and in accordance with, the terms of this Agreement as if such accrual had been pursuant to Section 3.1(a). For purposes of clarification, any accrual of Bonus Shares pursuant to this Section 3.1(l) shall be a contractual accrual and not an accrued stock dividend.

(m) Notwithstanding anything express or implied in this Agreement to the contrary, in the event of any transaction involving Radius and a Shell Company Successor pursuant to which such Shell Company Successor,

directly or indirectly, acquires Radius or all or substantially all of its assets, then (1) such transaction shall not be treated as an Event of Sale, (2) such Shell Company Successor shall succeed to all of the rights and obligations of Radius under this Agreement and (3) if the stock dividend feature of Section 3.1(a) hereof does not terminate pursuant to the first paragraph of Section 3.1(k), all references in this Agreement to the terms Series A-5 Preferred Stock and Series A-6 Preferred Stock shall be deemed and treated as if they were references to the applicable series of preferred stock of such Shell Company Successor into which, or for which, such Series A-5 Preferred Stock and such Series A-6 Preferred Stock was converted or exchanged, as applicable.

3.2 Bonus Shares to be Duly Authorized and Issued, Fully Paid and Non-Assessable. Radius covenants and agrees that it will take all such action as may be necessary to ensure that all Bonus Shares issued pursuant to this Agreement shall, at the time of delivery of the certificates for such Bonus Shares, be duly and validly authorized and issued and fully paid and non-assessable shares.

3.3 Stock Record Date. No Person shall be deemed to have become the holder of record of any Bonus Shares until the date that the Board of Directors declare such accrued Bonus Shares payable in accordance with Section 3.1(i) and any certificate for such accrued Bonus Shares shall be dated as of such date. Prior to such date, no Person shall be entitled to any rights of a stockholder of Radius with respect to the Bonus Shares which may be issuable pursuant to this Agreement including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights and shall not be entitled to receive any notice of any proceedings of Radius, except as provided herein.

3.4 Limitation. (a) Subject to Section 3.4(b), notwithstanding anything to the contrary expressed or implied in this Agreement, in the event that, at any time after Radius is acquired, directly or indirectly, by a Shell Company Successor, any accrual of Bonus Shares in accordance with the provisions of this Agreement would cause the cumulative number of Bonus Shares (calculated on an as converted to Common Stock basis) accrued pursuant to this Agreement from and after the effective date of such acquisition (whether or not such accrued Bonus Shares have been or are issued) to exceed [*]% of the issued and outstanding shares of capital stock of such Shell Company Successor as of such effective date and as of each Accrual Date after such effective date (calculated on an as converted to Common Stock basis and after giving effect to appropriate and equitable adjustments upon any stock splits, stock dividends, reverse stock splits, recapitalizations, mergers and other similar events), then no such accrual shall be made pursuant to this Agreement, and Radius shall, in lieu of such accrual, make payment of any Applicable Quarterly Amount in cash.

(b) The limitation imposed by Section 3.4(a) may be waived by Radius in its sole and absolute discretion at any time and from time to time. Any such waiver by Radius of such limitation in any particular instance shall not constitute a waiver of such limitation in any other instance.

Approximately Sixty Million Dollars ($60,000,000) in three equal installments. First installment to be issued by Radius. Second and

		Third installment to be issued by Surviving Corporation (See “Proposed Reverse Merger” below). For all purposes of this term sheet, the term Pro Rata Portion (as defined below) shall be based on $35,000,000 only and not the full $60,000,000 of gross proceeds to be raised in connection with the Series A-1 Offering. See Attachment. The term “Series A-1 Offering Existing Investor Available Amount” shall mean such $35,000,000 portion of such $60,000,000 in gross proceeds to be raised pursuant to the Series A-1 Offering.

Reverse Stock Split:		At any time prior to the closing of the first installment of the Series A-1 Offering (including immediately prior to such closing) the Company shall effect a 15:1 reverse stock split of all of its capital stock (the “Reverse Stock Split”). Any fractional shares resulting from computations made in connection with the Reverse Stock Split will be paid out in cash at such closing.

Series A-1 Original Purchase Price Per Share:		$8.142 (which price reflects the consummation of the Reverse Stock Split)

Rights Offering:		Each holder of the Company’s existing Series A Junior Convertible Preferred Stock, par value $.01 per share (the “Existing A Preferred”), Series B Convertible Redeemable Preferred Stock, par value $.01 per share (the “Existing B Preferred”), and Series C Convertible Preferred Stock, par value $.01 per share (the “Existing C Preferred” and together with the Existing A Preferred and the Existing B Preferred, the “Existing Preferred”), if such holder is an accredited investor under applicable United States securities laws, shall be given the opportunity to purchase such holder’s Pro Rata Portion (as defined below) of the Series A-1 Offering Existing Investor Available Amount.

Pro Rata Portion:		For purposes of the Series A-1 Offering, the term “Pro Rata Portion” shall mean, with respect to any holder of Existing Preferred, that percentage figure which expresses the ratio that (a) the number of shares of issued and outstanding Common Stock then owned by such holder of Existing Preferred bears to (b) the aggregate number of shares of issued and outstanding Common Stock then owned by all holders of Existing Preferred. For purposes of the computation set forth in clauses (a) and (b) above, all issued and outstanding securities held by holders of Existing Preferred that are convertible into or exercisable or exchangeable for shares of Common Stock (including any issued and issuable shares of Existing Preferred Stock) or for any such convertible, exercisable or exchangeable securities, shall be treated as having been so converted, exercised or exchanged at the rate or price at which such securities are convertible, exercisable or exchangeable for shares of Common Stock in effect at the time in question, whether or not such securities are at such time immediately convertible, exercisable or exchangeable.

Participation by Existing Preferred Stockholders:		Any holder of Existing Preferred that does not purchase its full Pro Rata Portion of the Series A-1 Offering Existing Investor Available

		Amount shall be forced to convert the Applicable Portion (as defined below) of such holder’s shares of Existing Preferred into shares of Common Stock, par value $.01 per share, of the Company on a 5-for-1 basis and shall forfeit any and all accrued dividends on the Applicable Portion of such holder’s Existing Preferred being converted into Common Stock. The term “Applicable Portion” means that percentage of such holder’s Pro Rata Portion not purchased by such holder in the Series A-1 Offering.

		Each holder of Existing C Preferred that participates in the Series A-1 Offering shall, subject to the “Super Pro Rata Participation” provisions set forth below, (a) exchange each remaining share of Existing C Preferred of such holder (after giving effect to the forced conversion provisions of the immediately preceding paragraph) for one share of Series A-2 Convertible Preferred Stock, par value $.01 per share (the “Series A-2 Stock”), and (b) forfeit any and all accrued dividends on such holder’s Existing C Preferred.

		Each holder of Existing B Preferred that participates in the Series A-1 Offering shall, subject to the “Super Pro Rata Participation” provisions set forth below, (a) exchange each remaining share of Existing B Preferred of such holder (after giving effect to the forced conversion provisions of the immediately preceding paragraph) for one share of Series A-3 Convertible Preferred Stock, par value $.01 per share (the “Series A-3 Stock”), and (b) forfeit any and all accrued dividends on such holder’s Existing B Preferred.

		Each holder of Existing A Preferred that participates in the Series A-1 Offering shall exchange each remaining share of Existing A Preferred of such holder (after giving effect to the forced conversion provisions of the immediately preceding paragraph) for one share of Series A-4 Convertible Preferred Stock, par value $.01 per share (the “Series A-4 Stock”).

Super Pro Rata Participation:		Notwithstanding the foregoing, any holder of Existing B Preferred or Existing C Preferred that purchases more than its full Pro Rata Portion of the Series A-1 Offering Existing Investor Available Amount shall, in connection with such holder’s exchange of shares of Existing Preferred Stock for shares of Series A-2 Stock or Series A-3 Stock, as applicable, in accordance with the provisions set forth above in this term sheet, not forfeit that amount of accrued dividends on such holder’s Existing Preferred equal to the dollar amount invested in the Series A-1 Offering by such holder that is in excess of its Pro Rata Portion of the Series A-1 Offering Existing Investor Available Amount (the “Super Pro Rata Amount”), but rather shall only forfeit accrued dividends in excess of the Super Pro Rata Amount and shall exchange the right to receive accrued dividends in an amount equal to the Super Pro Rata Amount for that number of additional shares of Series A-1 Stock obtained by dividing (a) such holder’s Super Pro Rata Amount by (b) the Series A-1 Original Purchase Price Per Share.

Going Forward Pay-to-Play:		Other than the potential forced conversion of shares of Existing Preferred into shares of Common Stock on a 5-for-1 basis as described under “Participation by Existing Preferred Stockholders” above, following the issuance of the Series A-1 Stock there will never be any pay-to-play provisions made applicable to, or implemented against, the New Preferred Stock (as defined below).

Conditions:		The closing of the Series A-1 Offering shall be conditioned upon (1) the prior or simultaneous execution and delivery of definitive documentation relating to the strategic alliance with, and related equity issuance to, Nordic (as defined below) and (2) the immediately subsequent closing of the Merger (as defined below).

Required Merger Approval:		In the definitive documentation for the purchase of shares of Series A-1 Stock, each investor will be required to (1) approve and adopt the Merger, as well as authorize the officers of the Company to execute and deliver such agreements, instruments and documents, for and in the name and on behalf of the Company, as such officer or officers may deem necessary, advisable or appropriate in order to effectuate the Merger, and (2) waive all rights, if any, under Section 262 of the Delaware General Corporation Law to seek an appraisal of any shares New Preferred Stock (as defined below) or Common Stock held by or acquired by such investor.

STRATEGIC ALLIANCE

Description:		Radius and Nordic Bioscience (“Nordic”) intend to enter into a strategic alliance under which Nordic will initially provide all services necessary and appropriate for the Phase 3 clinical trial for the subcutaneous formulation of BA058 (“Fracture Study”) (a detailed description of services will be included in the final strategic alliance agreement). The strategic alliance with Nordic may be extended to other BA058 clinical studies, including extension studies and transdermal formulation studies on terms to be agreed by the parties. In consideration for the services to be provided by Nordic, Radius will issue to Nordic the number of shares of Radius’ Series A-5 Convertible Preferred Stock, par value $.01 per share (the “Series A-5 Stock” and together with the Series A-1 Stock, the Series A-2 Stock, the Series A3 Stock, the Series A-4 Stock and the Series A-6 Stock described below, the “New Preferred Stock”) upon the execution of definitive documentation relating to the transaction (the “Initial Nordic Shares”) equal to the quotient (rounded to the nearest whole number) obtained by dividing (x) the United States Dollar equivalent of €371,864 by (y) the Series A-5 Purchase Price Per Share. The Initial Nordic Shares shall accrue quarterly dividends to be paid in the form of shares of Series A-6 Convertible Preferred Stock, par value $.01 per share (the “Series A-6 Stock”) as these services are delivered, as more fully described below.

PROPOSED REVERSE MERGER

Description:		Prior to the closing of the Series A-1 Offering, Radius shall have entered into an Agreement and Plan of Merger pursuant to which the Company would complete a reverse merger with a Form 10 Shell. The reverse merger would take place in two steps: First, the Form 10 Shell would form a wholly-owned subsidiary that would merge with and into the Company (the “Merger”) resulting in the Company becoming a wholly-owned subsidiary of the Form 10 Shell; and Second, the Company would be merged up and into the Form 10 Shell pursuant to Section 253 of the Delaware General Corporation Law in a “short-form merger” (the resulting corporation being hereinafter referred to as the “Surviving Corporation”).

Consideration:		As consideration for the Merger, the Stockholders of the Radius will receive, in exchange for their shares of New Preferred Stock or Common Stock of Radius, shares of preferred stock and common stock, as the case may be, in the Surviving Corporation with terms, rights and preferences substantially similar (subject to the conversion rights/ratio of the preferred stock described below) to those of the shares of equity of Radius held by such stockholder prior to the closing of the Merger. Upon the consummation of the Merger, shares of Common Stock of Radius will be exchanged for shares of common stock of the Surviving Corporation at a ratio of 1:1. Due to the number of shares of preferred stock that the Surviving Corporation currently has authorized, and to avoid having to file a proxy statement with the SEC in connection with increasing such number of authorized shares, upon the consummation of the Merger, shares of New Preferred Stock will be exchanged for shares of preferred stock of the Surviving Corporation at a 10:1 ratio (i.e., 10 shares of New Preferred Stock will be exchanged for one share of corresponding preferred stock of the Surviving Corporation). Any fractional shares resulting from computations made in connection with such exchange will be paid out in cash. Each share of preferred stock of the Surviving Corporation will have the voting power equivalent of ten shares of common stock of the Surviving Corporation. To maintain as-converted ownership percentages, following the Merger, shares of preferred stock of the Surviving Corporation will be convertible into shares of common stock of the Surviving Corporation at a ratio of 1:10 (i.e., 1 share of preferred stock will convert into 10 shares of common stock).

		Series A-5 Stock Accruing Dividend: Accruing dividend payable in shares of Series A-6 Stock, representing up to an aggregate €36,814,531 in value for the Fracture Study (such stock dividend shares, the “Bonus Shares”). The number of Bonus Shares that Nordic shall be entitled to receive in the aggregate shall accrue on a calendar quarterly basis starting with the calendar quarter in which the first subject is enrolled in the Phase III clinical trial to be conducted by Nordic. The quarterly amounts of such Bonus Shares shall be calculated based upon the estimated time that will be required to complete the clinical study (following enrollment of the first study subject), lock the study database, transfer the study database to Radius and for Radius to accept the Final Tables Listings and Figures for the clinical study based on the study database. The parties, acting through a Project Committee, will evaluate the study timeline and adjust the pro rata amount to account for delays or accelerations in the performance of such Fracture Study. The amount of each quarterly dividend shall be determined by dividing the portion of €36,814,531 to be accrued in such quarter by the Fair Market Value (as defined below) on the date the dividend accrues. “Fair Market Value” for purposes of this calculation will equal the greater of (i) the Series A-5 Purchase Price Per Share (as such price per share may be adjusted for any stock splits, stock dividends, reverse stock splits, recapitalizations, mergers and other similar events affecting such Series A-5 Stock), (ii) the price per share of the preferred stock or common stock sold by Radius or a Shell Company Successor (as defined below) in the then most recent equity financing closed by Radius or the Shell Company Successor prior to the applicable accrual date; and (iii) the average of the closing prices of the common stock of Radius or a Shell Company Successor, as the case may be, on a securities exchange (if such common stock is traded on an exchange) or the average of the closing sale prices or secondarily the closing bid prices of such common stock (if such common stock is regularly traded over-the-counter) over the twenty (20) calendar day period ending two (2) calendar days prior to the date the stock dividend accrues. “Shell Company Successor” means a shell company that (i) has securities registered under the Securities Exchange Act of 1934, as amended, (ii) has nominal operations and nominal assets (prior to any of the transactions described in clause (iii)) and (iii) directly or indirectly through one or more direct or indirect subsidiaries acquires Radius and/or all or substantially all of its assets or business (whether pursuant to a stock purchase, an asset purchase, a merger or any other similar transaction) and in consideration for such acquisition issues to the former stockholders of Radius shares of capital stock of such shell company. Upon any conversion of the Series A-5 Stock, the Bonus Shares will continue to be paid but shall be paid in shares of Common Stock.

		(d) the holders of Series A-4 Stock shall be entitled to receive, on a pari passu basis with the liquidation preference payable to the holders of all other shares of Series A-4 Stock but in preference to the liquidation preference payable to the holders of Common Stock, an amount per share equal to the Series A-4 Original Purchase Price Per share, plus any declared but unpaid dividends on such Shares of Series A-2 Stock; and
