Whereas Emisphere owns compounds and technology (including patents, patent applications, trade secrets, know-how and other intellectual property rights) and will develop pursuant to the Program (as defined below) certain compounds and technology, collectively the "EMISPHERE TECHNOLOGY"); and WHEREAS, Cubist produces, or is engaged in research to produce, therapeutic macromolecules and other compounds, has significant expertise in identifying and developing compounds that mediate a variety of disorders, and has proprietary compounds and technology (including patents, patent applications, trade secrets, know-how and other intellectual property rights presently owned or controlled by Cubist and to be developed by Cubist pursuant to the Program); and WHEREAS, Emisphere and Cubist desire to collaborate in research regarding the applicability of the Emisphere Technology to the oral delivery of Cubist's compounds, and to provide for certain rights and obligations of Emisphere and Cubist in the event such research produces commercially viable applications; and WHEREAS, Emisphere desires to grant certain options and rights to Cubist to jointly with Emisphere research and develop Cubist's products using the Emisphere Technology. *Confidential treatment requested: Material has been omitted and filed with the Commission <PAGE> NOW, THEREFORE, in consideration of the mutual promises and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Emisphere and Cubist (each a "Party" and together "the Parties") agree as follows: ARTICLE I RESEARCH PROGRAM 1.1 COLLABORATION. Cubist and Emisphere hereby agree to collaborate on a research and development program (the "PROGRAM"), as specified in Exhibit A of this Agreement and modified as needed during the term of this Agreement, to research and develop the use of the Emisphere Technology for the oral delivery of Daptomycin, its Cubist developed analogues and derivatives thereof (the "Compound"). Emisphere will make available to Cubist, Emisphere Technology including chemical compounds (the "Carriers") that it identifies as relevant to the Program, which can be used to facilitate and/or enable improved transport of therapeutic compounds through membranes. 1.2 PROGRAM MANAGEMENT. (a) Cubist and Emisphere shall establish a steering committee (the "STEERING COMMITTEE"). The function of the Steering Committee shall be to plan, coordinate and manage the Program. The Steering Committee is not intended to, replace any internal management procedures of either Party. Rather, it is intended to be a vehicle to ensure that the Program proceeds in a timely, coordinated, and well planned fashion. It shall be made up of a maximum of six (6) members, with an equal number appointed by each of Cubist and Emisphere and with a central contact person appointed by each Party. Each Party hereto shall name one member to be a co chairperson of the Steering Committee. Meetings of the Steering Committee will alternate between Emisphere's designated facility and Cubist's designated facility. The first responsibility of the Steering Committee shall be to establish and approve a work plan to assure the timely completion of the various tasks of the Program. The second responsibility of the Steering Committee shall be to define acceptance criteria (e.g., bioavailability, % absorption) which will be used to make the "go/no go" decisions with respect to continued research into and/or development of the use of the Carriers for oral delivery of the Compound (the "CRITERIA"). Cubist and Emisphere shall establish the Criteria within thirty (30) days of the Effective Date and shall determine whether the Criteria have been met. On at least a quarterly basis, the Steering Committee shall meet to review the results of the Program and to modify the *Confidential treatment requested: Material has been omitted and filed with the Commission <PAGE> work plan as necessary. On a quarterly basis or time frame agreed to by the parties, each party's respective patent counsel shall meet to discuss patent filings and intellectual property matters. (b) The Steering Committee shall keep minutes of its meetings, and shall be responsible only for the development and implementation of the work plan. If the members of the Steering Committee cannot agree jointly on a task in the work plan, it will be up to the Co-Chairmen to reach a decision. If the Co-Chairmen cannot reach agreement, the matter shall be brought to the CEO of Emisphere and CEO of Cubist. In the event that the CEO's cannot resolve the issues then Cubist shall make the final decision. Notwithstanding the preceding sentence, if the CEO's cannot resolve a matter that relates to the manufacture and qualification of the Carrier, and if Emisphere reasonably believes that the final decision by Cubist could materially adversely affect Emisphere's other then current research programs or collaborations or Emisphere's business, then Emisphere shall have the right to invoke the dispute resolution mechanism outlined in section 4.19 in which case Emisphere may suspend the Program and implementation of the decision by Cubist, pending completion of such dispute resolution mechanism. It is further understood and agreed by the Parties that Emisphere shall use its reasonable commercial efforts tonsure that it takes all reasonable steps necessary to be able to meet Cubist's needs for the manufacture of the Carrier. It is further understood and agreed by the Parties that Cubist shall use its reasonable commercial efforts to ensure that it takes all reasonable steps necessary to advance the progress of the development efforts. 1.3 TERM; TERMINATION. (a) The Agreement is in effect as of the Effective Date. Subject to articles 1.3(b), (c), (d), and (e), the Program shall proceed as outlined in Exhibit A. The Parties will determine whether the Criteria have been met. If the Criteria have been met, then the Program shall continue provided that the Steering Committee determines that the profile of the Compound itself does not preclude its further development (e.g. efficacy, toxicity, side effects, etc.). (b) If the Steering Committee determines that preclinical or clinical findings prevent initiation or completion of the Program with respect to the Emisphere Technology and/or the Compound, either Cubist or Emisphere will have the option of immediately terminating the Program. (c) Either Party may terminate this Agreement upon written notice to the other Party that such other Party has committed a material breach of *Confidential treatment requested: Material has been omitted and filed with the Commission <PAGE> this Agreement if, within [ ]* days of receipt of such notice, such breach has not been cured, or the Parties have not agreed in writing to amend the Agreement to waive such breach or to give extra time to cure such breach.

(f) Cubist may terminate this Agreement at any time for any reason upon [ ]* days notice to Emisphere. Should Cubist terminate this Agreement for any reason other than an inability of the Emisphere technology to deliver the drug via oral administration, then Cubist and Emisphere, at Emisphere's option, shall issue a joint press release indicating that the Agreement was terminated for reasons unconnected with the Emisphere technology. 1.4 PAYMENTS.
