CONVERTIBLE NOTE PURCHASE AGREEMENT

THIS CONVERTIBLE NOTE PURCHASE AGREEMENT (this “Agreement”) is made as of November 2, 2012, by and among GeNO LLC, a Delaware limited liability company (the “Company”), and the purchasers (each individually a “Purchaser,” and collectively the “Purchasers”) named on the Schedule of Purchasers attached hereto as Exhibit A (the “Schedule of Purchasers”).

WHEREAS, the Purchasers desire to loan the Company capital in an aggregate principal amount of up to $3,000,000 (the “Total Authorized Borrowing Amount”).

NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

1. Definitions; Sale and Issuance of the Notes.

1.1 Definitions. As used in this Agreement, terms not otherwise defined shall have the meanings set forth on Exhibit B attached to this Agreement.

1.2 Sale and Issuance of the Notes. Each Purchaser agrees to purchase, and the Company agrees to sell and issue to each Purchaser a Note in the amount equal to the Purchaser’s Principal Amount.

1.3 Closings. The initial closing (the “Initial Closing”) of the purchase and sale of the Notes shall take place at the offices of the Company, 2941 Oxbow Circle, Cocoa, FL 32926 at 10:00 a.m. on the date hereof, or at such other date as the Company and the Purchasers mutually agreed upon, orally or in writing. Additional closings (along with the Initial Closing, a “Closing”) may occur from time to time up to the Total Authorized Borrowing Amount in the Company’s sole discretion.

1.4 Agreements. Each Purchaser of a Note shall become a party to this Agreement by executing a counterpart signature page hereto and shall be entitled to receive a Note in accordance with this Agreement.

2. Terms of the Notes.

2.1 Financing, License or Sale Event.

(a) New Equity Financing. In the event a New Equity Financing occurs prior to the Maturity Date, each Purchaser shall have the option (a) to receive repayment of all or some of the Purchaser’s Outstanding Loan Amount and/or (b) to convert all or some of the Purchaser’s Outstanding Loan Amount into Conversion Shares. The number of Conversion Shares to be issued upon such conversion shall be equal to the quotient obtained by dividing (i) the Purchaser’s Outstanding Loan Amount on the date of conversion by (ii) a price equal to eighty percent (80%) of the New Equity Share Price (the “Conversion Price”). The New Equity Share Price is the lower of (a) the price of Equity Securities issued to The Medicines Company pursuant to a license agreement, if any, entered into with the Company and (b) the price per share of the Equity Securities issued and sold to venture capital or other financial institutional or strategic investors before the Maturity Date in the next New Equity Financing after the date of this Agreement. In addition to the foregoing, upon conversion of the Purchaser’s Outstanding Loan Amount into Conversion Shares the Company shall also issue to each Purchaser a New Equity Warrant to purchase such number of Equity Securities as is equal to the quotient obtained by dividing (i) 20% of such Purchaser’s Principal Amount by (ii) the New Equity Share Price. At least ten (10) days prior to the closing of a New Equity Financing, the Company shall notify the Purchasers in writing of the terms under which the Equity Securities of the Company will be sold in a New Equity Financing. The issuance of the Conversion Shares pursuant to the conversion of each Note and the Warrant Shares upon exercise of the New Equity Warrants shall be upon, and subject to, the same terms and conditions applicable to the Equity Securities sold in a New Equity Financing.

(b) Extraordinary Transaction. In the event an Extraordinary Transaction occurs on or before the Maturity Date (and prior to the New Equity Financing), each Purchaser shall have the option (a) to receive repayment of all of the Purchaser’s Outstanding Loan Amount and/or (b) to receive a multiple of the applicable Principal Amount based upon the Value of the Transaction as follows:

(i) 1.5 times the applicable Principal Amount for an Extraordinary Transaction valued at $50 million or less;

(ii) 5.0 times the applicable Principal Amount for an Extraordinary Transaction valued at $400 million or more; and

(iii) a multiple of the applicable Principal calculated on a linear basis (and to the nearest one-one thousandth of a decimal (“0.000”)) for an Extraordinary Transaction valued at more than $50 million and less than $400 million.

(c) No Fractional Shares. Upon the conversion of a Note into Conversion Shares, in lieu of any fractional shares to which the holder of the Note would otherwise be entitled, the Company shall pay the Purchaser cash equal to such fraction multiplied by the Conversion Price.

(d) Other Agreements. Each Purchaser understands and agrees that the conversion of the Purchaser’s Note into Conversion Shares and the exercise of the applicable New Equity Warrant for Warrant Shares may require the Purchaser’s execution of certain agreements in the form agreed to by investors in a New Equity Financing, including restrictions regarding, among other things, registration rights, co-sale rights, rights of first refusal, rights of first offer and voting rights, relating to such securities, and the Company’s then current Limited Liability Company Operating Agreement (“LLC Operating Agreement”).

- 2 -

(e) Mechanics of Conversion. The Company shall not be required to issue or deliver the Conversion Shares until the Purchaser has surrendered the Purchaser’s Note to the Company for cancellation. Conversion may be made contingent upon the closing of a New Equity Financing.

(f) Mechanics of Exercise. The Company shall not be required to issue or deliver the Warrant Shares until the Purchaser has surrendered the Purchaser’s New Equity Warrant to the Company.

2.2 Events of Default. Each of the following events shall be considered an event of default (each, an “Event of Default”) with respect to each Note:

(a) The Company shall default in the payment of any part of any of the Outstanding Loan Amounts on the Notes for more than thirty (30) days after the Maturity Date or at a date fixed by acceleration or otherwise;

(b) The Company shall make an assignment for the benefit of creditors, or shall admit in writing its inability to pay its debts as they become due, or shall file a voluntary petition for bankruptcy, or shall file any petition or answer seeking for itself any reorganization, arrangement, composition, readjustment, dissolution or similar relief under any present or future statute, law or regulation, or shall file any answer admitting the material allegations of a petition filed against the Company in any such proceeding, or shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of the Company, or of all or any substantial part of the properties of the Company, or the Company or its respective managers or majority shareholders shall take any action looking to the dissolution or liquidation of the Company; or

(c) Within ninety (90) days after the commencement of any proceeding against the Company seeking any bankruptcy reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceeding shall not have been dismissed, or within sixty (60) days after the appointment without the consent or acquiescence of the Company or any trustee, receiver or liquidator of the Company of all or any substantial part of the properties of the Company, such appointment shall not have been vacated.

2.3 Remedies. Upon the occurrence of an Event of Default, at the option and upon the declaration of the Majority Note Holders, the entire Outstanding Loan Amount on all of the Notes shall, without presentment, demand, protest, or notice of any kind, all of which are hereby expressly waived, be forthwith due and payable, and such holders may, immediately and without expiration of any period of grace, enforce payment of all amounts due and owing under the Notes and exercise any and all other remedies granted to it at law, in equity or otherwise. The Company shall promptly give notice to all other Purchasers if the Majority Note Holders exercise their rights under this Section 2.3.

3. Representations and Warranties of the Company. As of the Initial Closing, the Company hereby represents and warrants to each Purchaser:

3.1 Organization, Good Standing and Qualification. The Company is a limited liability company duly organized, validly existing, and in good standing under the laws of the State of Delaware and has all requisite limited liability company power and authority to carry on its business as now conducted. The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a material adverse effect on its business or properties.

3.2 Authorization. Except for the authorization and issuance of the Conversion Shares to be issued in connection with the conversion of the Notes, the New Equity Warrants, and the Warrant Shares to be issued in connection with the exercise of the New Equity Warrants pursuant to Section 2.1, all limited liability company action has been taken on the part of the Company, its officers, managers, and shareholders necessary for the authorization, execution and delivery of this Agreement and the Notes. Except as may be limited by applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights, the Company has taken all corporate action required to make all of the obligations of the Company reflected in the provisions of this Agreement and the Notes, the valid and enforceable obligations they purport to be. The issuance of the Notes, the New Equity Warrants, and their subsequent conversion into Conversion Shares or exercise for Warrant Shares are not subject, and will not be subject, to preemptive rights or other “rights to participate” of any shareholders of the Company.

3.3 Compliance with Other Instruments. The Company is not (a) in violation of any provision of its Certificate of Formation or LLC Operating Agreement, (b) in violation of or default under any instrument, judgment, order, writ, decree or contract to which it is a party or by which it is bound, or (c) in violation of or default under any provision of any federal or state statute, rule or regulation applicable to the Company, except, in the case of (b) and (c), such violations or defaults that will not result, either individually or in the aggregate, in any material adverse change in the assets, condition, prospects or affairs of the Company and its subsidiaries, taken as a whole, financially or otherwise (“Material Adverse Effect”). Neither the authorization, execution and delivery of this Agreement, nor the issuance and delivery of the Notes will constitute or result in a material default or violation of any law or regulation applicable to the Company or any material term or provision of the Company’s current Certificate of Formation or LLC Operating Agreement or any material agreement or instrument by which it is bound or to which its properties or assets are subject.

- 4 -

3.4 Valid Issuance of Shares. The Conversion Shares to be issued and delivered upon conversion of the Notes and the Warrant Shares to be issued and delivered upon exercise of the New Equity Warrants will be duly and validly issued, fully paid and nonassessable and, based in part upon the representations and warranties of the Purchasers in this Agreement, will be issued in compliance with all applicable federal and state securities laws.

4. Representations and Warranties of Each Purchaser. Each Purchaser hereby represents and warrants to the Company as of the Closing that:

4.1 Authorization. This Agreement constitutes the Purchaser’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (a) applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (b) laws relating to the availability of specific performance, injunctive relief or other equitable remedies. The Purchaser has full power and authority to enter into this Agreement.

4.2 Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the Purchaser’s representation to the Company that the Notes, the Conversion Shares, any capital stock issuable upon conversion of the Conversion Shares, the New Equity Warrants, Warrant Shares, and any capital stock issuable upon conversion of the Warrant Shares (collectively, the “Securities”) will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. The Purchaser does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Securities.

4.3 Disclosure of Information. The Purchaser has received all the information the Purchaser considers necessary or appropriate for deciding whether to acquire the Securities. The Purchaser has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities.

4.4 Investment Experience. The Purchaser (a) is an investor in securities of companies in the development stage, (b) has such knowledge and experience in financial or business matters that the Purchaser is capable of evaluating the merits and risks of the investment in the Securities and (c) is able to bear the economic risk of an entire loss of the investment. If other than an individual, the Purchaser also represents it has not been organized solely for the purpose of acquiring the Securities.

- 5 -

4.5 Accredited Investor. The Purchaser is an “accredited investor” within the meaning of Rule 501 of Regulation D of the Securities and Exchange Commission (the “SEC”), as presently in effect. The Purchaser has completed and returned to the Company the Investor Questionnaire attached as Exhibit D.

4.6 Non-U.S. Purchasers. If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the “Code”)), the Purchaser hereby represents that the Purchaser has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Securities, (b) any foreign exchange restrictions applicable to such purchase, (c) any government or other consents that may need to be obtained in connection with such purchase, and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Securities. The Company’s offer and sale and the Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the Purchaser’s jurisdiction.

4.7 Restricted Securities. The Purchaser understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. The Purchaser is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

4.8 Legends. It is understood that the Securities may bear the following legends:

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.”

5. Other Agreements.

5.1 Limitations on Disposition by Purchasers. Without in any way limiting the representations and warranties set forth in Section 4, each Purchaser agrees not to make any disposition of all or any portion of the Securities:

(b) unless the transfer is made in accordance with the Company’s LLC Operating Agreement restricting transfers; and

(c) either (i) the Purchaser has notified the Company of the proposed disposition and has furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition and, if reasonably requested by the Company, the Purchaser shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act; or (ii) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement.
