(1) This percentage is calculated based upon 16,046,894 shares of outstanding Common Stock, which consists of: (i) 555,594 shares of Common Stock, and (ii) an aggregate of 15,491,300 shares of Common Stock issuable upon conversion of outstanding Preferred Stock, outstanding as of May 17, 2011 following completion of the Merger (as defined below) as disclosed in the Issuer’s Current Report on Form 8-K, filed with the SEC on May 23, 2011. Because shares of Preferred Stock vote together with Common Stock on an as-converted basis, such percentage reflects the Reporting Person’s voting percentage of the Issuer’s outstanding capital stock. If the percentage calculation was calculated in accordance with Rule 13d-3(d)(1) promulgated under the Exchange Act, which requires that only the outstanding shares of Common Stock and shares issuable upon conversion of derivative securities held by the Reporting Person (i.e., 409,400 shares of Common Stock issuable upon conversion of the Preferred Stock), it would result in an applicable percentage of 42.4%.

Item 3. Source and Amount of Funds or Other Consideration
Pursuant to an Agreement and Plan of Merger dated April 25, 2011 (the “Merger Agreement”), by and among MPM Acquisition Corp. (the “Company”), RHI Merger Corp., a Delaware corporation and wholly owned subsidiary of the Company (“MergerCo”), and Radius Health, Inc., a Delaware corporation (“Target”), MergerCo merged with and into Target, with Target remaining as the surviving entity and a wholly-owned operating subsidiary of the Company. This transaction is referred to as the “Merger.” The Merger was effective as of May 17, 2011, upon the filing of a certificate of merger with the Delaware Secretary of State. At the effective time of the Merger (the “Effective Time”), the legal existence of MergerCo ceased and all of the shares of Target’s common stock, par value $.01 per share (the “Target Common Stock”), and shares of Target’s preferred stock, par value $.01 per share (the “Target Preferred Stock”), that were outstanding immediately prior to the Merger were cancelled and each outstanding share of Target Common Stock outstanding immediately prior to the Effective Time was automatically converted into the right to receive one share of the Company’s common stock and each outstanding share of Target Preferred Stock outstanding immediately prior to the Effective Time was automatically converted into the right to receive one-tenth of one share of the Company’s preferred stock as consideration for the Merger.
Following the Merger on May 17, 2011, the Company’s Board of Directors approved a transaction pursuant to which Target merged with and into the Company, leaving the Company (now the Issuer) as the surviving corporation (the “Short-Form Merger”). In connection with the Short-Form Merger, the Company relinquished its corporate name and assumed in its place the name “Radius Health, Inc.” The Short-Form and name change became effective on May 17, 2011, upon the filing of a Certificate of Ownership and Merger with the Delaware Secretary of State.
Following the Merger and the Short-Form Merger, Biotech Growth owns 40,940 shares of Series A-1 Preferred Stock which may be converted at the election of the holder into 409,400 shares of Issuer Common Stock (the “Biotech Growth Shares”).
Item 4. Purpose of Transaction
BB Biotech and Biotech Growth acquired the Biotech Growth Shares for investment purposes.

Pursuant to the Series A-1 Convertible Preferred Stock Purchase Agreement by and among Target and certain investors listed on Schedule I thereto, dated as of April 25, 2011, and as amended on May 11, 2011 (the “Purchase Agreement”), BB Biotech and Biotech Growth committed to purchasing an aggregate of an additional 81,880 shares of Series A-1 Preferred Stock from the Issuer in a series of private placements at a purchase price per share of $81.42 upon notice from the Issuer (the “Future Funding Obligations”). In the event that an investor does not timely and completely fulfill its Future Funding Obligation, all shares of preferred stock held by the investor will be automatically converted to Common Stock at the rate of one share of Common Stock for every ten shares of preferred stock and the Common Stock resulting from such conversion would then be subject to a repurchase right at par value in favor of the Issuer.
Depending on market conditions, its continuing evaluation of the business and prospects of the Issuer and other factors, any or all of the Reporting Persons may dispose of or acquire additional shares of the Issuer in compliance with applicable law. Except as set forth above, none of the Reporting Persons has any present plans which relate to or would result in:

  (e)   Any material change in the present capitalization or dividend policy of the Issuer;
 
  (f)   Any other material change in the Issuer’s business or corporate structure including but not limited to, if the Issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by section 13 of the Investment Company Act of 1940;
 
  (g)   Changes in the Issuer’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;
