With respect to sales of Products invoiced in a currency other than Dollars, the Net Sales and amounts due to CFF hereunder shall be expressed in the domestic currency of the party making the sale, together with the Dollar equivalent of the amount payable to CFF, calculated by translating foreign currency sales into Dollars in accordance with Corbus’s accounting policies. If any licensee or sublicensee makes any sales invoiced in a currency other than its domestic currency, the Net Sales shall be converted to its domestic currency in accordance with the licensee’s or sublicensee’s normal accounting principles. Corbus shall keep accurate records in sufficient detail to enable the amounts due hereunder to be determined and to be verified by CFF.

4.4.2 Independent Accountant. Upon the written request of CFF, at CFF’s expense and not more than one time in the twelve (12) month period following the receipt by CFF of the report required under Section 4.4.1, Corbus shall permit an independent accountant selected by CFF to have access during normal business hours to those records of Corbus as may be reasonably necessary to verify the accuracy of the report furnished by Corbus pursuant to this Section 4.4. CFF shall pay the cost of any such examination, provided, however, that if such examination determines that actual Net Sales were five percent (5%) or greater than the amount reported by Corbus to CFF, in addition to promptly paying CFF for any additional royalty then due, Corbus shall reimburse CFF for its reasonable and documented expenses associated with such examination.

4.4.3 Interest. In case of any delay in payment by Corbus to CFF not occasioned by force majeure in accordance with Section 11.4, Interest shall be calculated from the tenth (10^th) day after the date upon which the applicable payment first becomes due from Corbus.

4.5 Transferee Liability. In the event of a license, sale or other transfer of the Product and/or Development Plan Technology, Corbus shall cause the licensee, buyer or other transferee to agree to be jointly and severally liable with Corbus for the royalties specified in Section 4.1 and 4.2, and failing that, such license, sale or other transfer shall be null and void.

ARTICLE V – CONFIDENTIALITY

5.1 Confidentiality.

5.1.1 Definition of Confidential Information. For purposes of this Agreement, “Confidential Information” shall mean all information Recipient received from the Discloser in connection with this Agreement, including (a) the financial terms of this Agreement and any other terms of this Agreement that a Party believes disclosure of which would be harmful to it, and (b) any other trade secrets, confidential or proprietary information, or any other knowledge, information, data, reports, documents or materials, owned, developed or possessed by Discloser(as defined below) whether in tangible or intangible form, the confidentiality of which Discloser takes reasonable measures to protect. “Confidential Information” shall not, however, include any information of Discloser that: (a) is already known to Recipient (as defined below) at the time of its disclosure; (b) becomes publicly known through no wrongful act of Recipient; (c) is received from a Third Party free to disclose it to Recipient and without any obligations to Discloser to keep confidential; (d) is independently developed by Recipient without use of the Confidential Information; or (e) is communicated to a Third Party without confidentiality requirements with express written consent of Discloser.

During the term of this Agreement and for a period of five (5) years thereafter, each Party (“Recipient”) shall hold all Confidential Information it receives or received from the other Party (“Discloser”) in strict confidence, and, other than as provided herein or without first obtaining the prior written consent of Discloser, Recipient shall not disclose any Confidential Information of Discloser to any Person, except to directors, officers, employees, consultants, committee members, volunteers, contractors, subcontractors, licensees, sublicensees, accountants or counsel of Recipient who have a need to know, who are subject to terms of confidentiality that are no less stringent than such confidentiality terms under this Agreement and who have been informed of the confidential nature of the information. Recipient shall use not less than a reasonable degree of care to protect such Confidential Information of Discloser.

5.1.3 Required Disclosure. Notwithstanding Section 5.1.2 above, Recipient’s disclosure of Confidential Information shall not be prohibited if such disclosure is required by a legally binding requirement; provided, however, that, Recipient shall have first given prompt notice to Discloser of any possible requirement and Discloser shall have been afforded a reasonable opportunity to prevent or limit such disclosure (the “Recipient Notice Requirement”); provided, further, that the Recipient Notice Requirement shall not apply to proceedings which, by applicable law, are of a nature that the existence of such proceedings may not be disclosed or made public in which case Recipient shall take all legally available measures to minimize or avoid the public disclosure of Discloser Confidential Information. In the event that Recipient discloses any Discloser Confidential Information pursuant to the immediately preceding sentence, Recipient shall cooperate with Discloser, at Discloser’s sole cost and expense, in the prosecution of any appeal that Discloser decides to pursue. For any disclosures of this Agreement required by the Securities and Exchange Commission or other body regulating Corbus’s or its Affiliates’ securities (“Securities Regulatory Authority”), Corbus shall exercise good faith efforts to give confidential treatment of the information described in Section 5.1.1, and Corbus shall provide CFF with contemporaneous copies of the requests for confidential treatment filed with such Securities Regulatory Authority.

5.2.3 Advanced Written Copy. In each instance, the Party desiring to issue any press release or to make any public announcement shall provide the other Party with a written copy of the proposed release or announcement in sufficient time prior to public release to allow such other Party to comment upon such release or announcement prior to its public release.

Notwithstanding the foregoing or any contrary provision contained herein, in connection with: any description by Corbus or its Affiliates of its portfolio and of its industry discovery and Development Plan, Corbus shall be entitled to use and/or disclose, and CFF hereby pre-approves Corbus’s use and/or disclosure of: (i) a general description of CFF, (ii) the existence and a general description of the nature of this Agreement (excluding financial terms), and (iii) a general description of the nature of the Development Plan consistent with the confidentiality terms herein.

ARTICLE VI – PUBLICATION

The Parties shall publish the Results of the Phase 2 Clinical Trial at the earliest opportunity that is consistent with the protection of the confidentiality of Development Plan Technology. Corbus reserves the first right to publish or publicly present the data generated during the performance of, or as a result of, the Development Plan (the “Results”), subject to the following terms and conditions. To the extent Corbus decides not to publish or publicly present the Results, Corbus shall in its sole discretion allow CFF to publish or publicly present such Results in accordance with this Article VI, and such consent will be binding if, and only if, provided in writing in accordance with the notice provisions contained herein. The Party proposing to publish or publicly present the Results (the “Publishing Party”) will submit a draft of any proposed manuscript, speech, poster or other disclosure to the other Party (the “Non-Publishing Party”) for comments at least sixty (60) days prior to submission for publication or oral presentation. The Non-Publishing Party shall notify the Publishing Party in writing within thirty (30) days of receipt of such draft with its comments, which shall be reasonably incorporated by the Publishing Party. The comments of the Non-Publishing Party shall include but not be limited to whether such draft contains (a) information of the Non-Publishing Party which it considers to be Confidential Information under the provisions of Article V hereof, (b) information that if published would have an adverse effect on a Patent which the Non-Publishing Party intends to file or has filed, or (c) information, including but not limited to chemical structures of a Product, which the Non-Publishing Party reasonably believes would be likely to have a material adverse impact on the development or commercialization of a Product. In any such notification, the Non-Publishing Party shall indicate with specificity its suggestions regarding the manner and degree to which the Publishing Party may disclose such information. In the case of item (a) above, no Party shall publish the Confidential Information of the other Party without the prior written consent of such other Party in violation of Article V of this Agreement. In the case of item (b) above, the Non-Publishing Party may request a delay and the Publishing Party shall delay such publication, for a period not exceeding an additional ninety (90) days, to permit the timely preparation and filing of a patent application or an application for a certificate of invention on the information involved. In the case of item (c) above, if the Publishing Party shall disagree with the Non-Publishing Party’s assessment of the impact of the publication, then the issue shall be referred to the Program Coordinator of each Party who shall attempt in good faith to reach a fair and equitable resolution of this disagreement. If the disagreement is not resolved in this manner within fourteen (14) days of referral to the respective Program Coordinators, then the decision of publication shall be subject to the Dispute Resolution provisions at Section 11.2, subject always to the confidentiality provisions of Article V hereof. The Parties agree that authorship of any publication will be determined based on the customary standards then being applied in the relevant scientific journal.

Corbus shall acknowledge the financial support of CFF in all Development Plan publications.

ARTICLE VII – INDEMNIFICATION AND INSURANCE

7.1 Indemnification by Corbus. Corbus shall indemnify, defend and hold harmless CFF, its Affiliates, and their respective directors, officers, employees and agents (including, without limitation, the CFF Designees) (each, a “CFF Indemnitee”), from and against any and all claims, suits and demands of Third Parties and losses, liabilities, damages for personal injury, property damage or otherwise, costs, penalties, fines and expenses (including reasonable fees of attorneys) (collectively, “Losses”) arising out of or resulting from: (a) the conduct of the Development Plan by Corbus and any breach of, or inaccuracy in, any of representations or warranties made by Corbus in this Agreement, or any breach or violation of any covenant or agreement of Corbus in or pursuant to this Agreement; and (b) any claim of infringement or misappropriation of intellectual property with respect to the Development Plan or any Product. Corbus will have no obligation to indemnify CFF to the extent that the Losses arise out of or result from, directly or indirectly, any breach of, or inaccuracy in, any representation or warranty made by CFF in this Agreement, or any breach or violation of any covenant or agreement of CFF in or pursuant to this Agreement, or the negligence or willful misconduct by or of any of the CFF Indemnitees.

7.2 Claims Procedures. Each CFF Indemnitee shall give notice Corbus promptly after receipt by a CFF Indemnitee of notice of the commencement of any action, suit or proceeding. Subject to Section 7.3, Corbus shall have the right to assume and manage the defense thereof (with counsel reasonably satisfactory to the CFF Indemnitee), including the right to settle, compromise and/or litigate with respect to any such claim (but only after obtaining Corbus’s prior written consent with respect to any proposed settlement, compromise or litigation; provided, however, that Corbus shall not be required to obtain the CFF Indemnitee’s prior written consent in connection with any proposed settlement, compromise or litigation if, in connection with and following any such settlement, compromise or litigation, the CFF Indemnitee (a) has no liability (monetary or otherwise), (b) has not waived any of its rights and has not admitted to any wrongdoing or guilt, (c) is not subject to any injunction or other equitable or non-monetary relief, and (d) receives a full and unconditional release of all applicable claims and liability).

7.3 Participation; Assuming Control of the Defense. Notwithstanding Section 7.2 above, CFF may participate in the defense of any claim at its sole expense, with counsel reasonably acceptable to Corbus; provided, however, if (a) there is a conflict of interest that would prevent Corbus, on the one hand, and CFF, on the other hand, from being represented by a single law firm in the defense of such action; in each such instance, or (b) there shall be one or more additional or other defenses available to CFF that are not available to Corbus, then in each such instance Corbus shall pay the reasonable fees and expenses of one law firm serving as counsel for CFF, which law firm shall be subject to the prior consent of Corbus, which consent shall not be unreasonably withheld, conditioned or delayed.

7.4 Insurance. Corbus shall maintain at its own expense, with a reputable insurance carrier, coverage for Corbus, its Affiliates, and their respective employees written on a per occurrence basis commensurate with a reasonable assessment of the risks associated with the conduct of the Development Plans. Maintenance of such insurance coverage will not relieve Corbus of any responsibility under this agreement for damages in excess of insurance limits or otherwise. Corbus shall provide CFF with an insurance certificate from the insurers, brokers or agents evidencing the applicable insurance coverage. At its request, CFF may review Corbus’ insurance coverages no more than one time per year.

7.5 Limitation of Liability. Neither Party shall be liable to the other Party for any special, indirect, incidental, consequential, punitive or exemplary damages, including, but not limited to, lost profits, in connection with such Party’s breach of this Agreement.

ARTICLE XI – MISCELLANEOUS PROVISIONS

11.1 Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Maryland.

11.2 Dispute Resolution.

11.2.1 In the event of any dispute, claim or controversy arising out of, relating to or in any way connected to the interpretation of any provision of this Agreement, the performance of either Party under this Agreement or any other matter under this Agreement, including any action in tort, contract or otherwise, at equity or law (a “Dispute”), either Party may at any time provide the other Party with written notice specifying the nature and terms of such Dispute in reasonable detail. As soon as practicable after receipt of such notice, the chief executive officers of each of the Parties or their designees shall meet at a mutually agreed upon time and location for the purpose of resolving such Dispute. Each Party shall engage in good faith discussions and/or negotiations for a period of up to thirty (30) days to attempt to resolve the Dispute or negotiate an interpretation or revision of the applicable portion of this Agreement which is mutually agreeable to both Parties without the necessity of formal dispute resolution procedures relating thereto.

11.2.2 In the event that such Dispute is not resolved by the Parties in accordance with subparagraph (a), either Party may pursue the resolution of such Dispute in a court of competent jurisdiction.

11.3 Waiver. No provision of this Agreement may be waived except in writing by both Parties hereto. No failure or delay by either Party hereto in exercising any right or remedy hereunder or under applicable law will operate as a waiver thereof, or a waiver of any right or remedy on any subsequent occasion.

11.4 Force Majeure. Neither Party will be in breach hereof by reason of its delay in the performance of or failure to perform any of its obligations hereunder, if that delay or failure is caused by strikes, acts of God or the public enemy, riots, incendiaries, interference by civil or military authorities, compliance with governmental priorities for materials, or any fault beyond its reasonable control. In such event Corbus or CFF, as the case may be, shall immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

11.5 Severability. Should one or more provisions of this Agreement be or become invalid, then the Parties hereto shall attempt to agree upon valid provisions in substitution for the invalid provisions, which in their economic effect come so close to the invalid provisions that it can be reasonably assumed that the Parties would have accepted this Agreement with those new provisions. If the Parties are unable to agree on such valid provisions, the invalidity of such one or more provisions of this Agreement shall nevertheless not affect the validity of the Agreement as a whole, unless the invalid provisions are of such essential importance for this Agreement that it may be reasonably presumed that the Parties would not have entered into this Agreement without the invalid provisions.

11.6 Assignment. This Agreement may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party; provided, however, that either Party may assign this Agreement, without the consent of the other Party, (i) to any of its Affiliates, if the assigning Party unconditionally guarantees the full performance of its Affiliate’s obligations hereunder, or (ii) in connection with such Party’s merger, consolidation or transfer, license or sale of all or substantially all of the assets of such Party to which this Agreement relates, provided, that the successor, surviving entity, purchaser of assets, transferee, or other similar party, as applicable, expressly assumes in full in writing such Party’s obligations under this Agreement. Any purported assignment in contravention of this Section 11.6 shall, at the option of the non-assigning Party, be null and void and of no effect. No assignment shall release either Party from responsibility for the performance of any accrued obligation of such Party hereunder. This Agreement shall be binding upon and enforceable against the successor to, or any permitted assignees from, either of the Parties hereto.

11.7 Counterparts. This Agreement may be executed in duplicate, each of which shall be deemed to be original and both of which shall constitute one and the same Agreement.

11.8 No Agency. Nothing herein contained shall be deemed to create an agency, joint venture, partnership or similar relationship between CFF and Corbus. Notwithstanding any of the provisions of this Agreement, neither Party to this Agreement shall at any time enter into, incur, or hold itself out to Third Parties as having authority to enter into or incur, on behalf of the other Party, any commitment, expense, or liability whatsoever, and all contracts, expenses and liabilities in connection with or relating to the obligations of each Party under this Agreement shall be made, paid, and undertaken exclusively by such Party on its own behalf and not as an agent or representative of the other.

11.9 Notice. All communications between the Parties with respect to any of the provisions of this Agreement will be sent to the addresses set out below, or to such other addresses as may be designated by one party to the other by notice pursuant hereto, by prepaid, certified air mail (which shall be deemed received by the other Party on the seventh (7^th) business day following deposit in the mails), or by facsimile transmission, or other electronic means of communication (which shall be deemed received when transmitted), with confirmation by first class letter, postage pre-paid, given by the close of business on or before the next following business day, or by a nationally recognized overnight courier (which shall be deemed received on the date of delivery):

11.10 Headings. The paragraph headings are for convenience only and will not be deemed to affect in any way the language of the provisions to which they refer.

11.11 Entire Agreement. This Agreement contains the entire understanding of the Parties relating to the matters referred to herein, and may only be amended by a written document, duly executed on behalf of the respective Parties.

11.12 No Impairment. Corbus will not, by amendment of its organizational or governing documents, or through reorganization, recapitalization, consolidation, merger, dissolution, sale, transfer or assignment of assets, issuance of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms, provisions, covenants or agreements of this Agreement, but rather will at all times in good faith assist in the carrying out of all such terms, provisions, covenants and agreements and in the taking of all such actions as may be necessary, advisable or appropriate in order to protect the rights of CFF against impairment.

IN WITNESS WHEREOF, the undersigned have executed this Research, Development and Commercialization Agreement as of the date first written above.

Exhibit A

Development Plan

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase 2

Trial to Evaluate Efficacy and Safety of Lenabasum in Cystic Fibrosis

INVESTIGATIONAL PRODUCT: Lenabasum

INDICATION: Cystic fibrosis

INVESTIGATIONAL SITES/LOCATIONS: Up to 100 sites in North America, Europe, Israel and Australia are planned

OBJECTIVES AND ENDPOINTS:

STUDY DESIGN:

This is a multicenter, double-blind, randomized, placebo-controlled, parallel group trial of efficacy and safety of treatment of CF subjects with lenabasum 20 mg BID and lenabasum 5 mg BID.

This trial includes analyses of event rate of and time to PEx. In this study, primary definition of PEx is based on the physician decision to treat with oral, intravenous or inhaled antibiotic(s) in the presence of at least 4/12 Fuch’s criteria. [*].

The target population is males and females with CF ≥ 12 years of age with FEV1 ≥ 40% predicted and < 100% predicted in 12 months before screening. The target population will be enriched for subjects with increased risk of a new PEx [*]. Subjects must have 2 or 3 new PEx treated with intravenous (IV) antibiotics in the 12 months before screening. Alternatively, if the subject had only 1 new PEx treated with IV antibiotics in the last 12 months, then that subject must have ≥ 1 other new PEx treated with oral antibiotics in the last 12 months before screening; [*].

See Table 1 below for the eligibility criterion by number of new PEx in the 12 months before screening.

Table 1 Eligibility by Number of New PEx in 12 Months before Screening

[*] subjects will be screened to identify a target of 415 eligible subjects. [*].

Subjects will be randomized centrally to treatment assignment before dosing in a 2:1:2 ratio to 1 of 3 treatment cohorts:

1. Cohort 1: Lenabasum 20 mg BID, n = 166

2. Cohort 2: Lenabasum 5 mg BID, n = 83

3. Cohort 3: Placebo BID, n = 166.

[*].

Duration and Visits

[*]. Active dosing with study drug is 28 weeks. [*].

[*] they will return 4 weeks after the last dose of study drug [*].

[*].

[*].

Efficacy Assessments

Safety Assessments

STUDY SCHEMATIC

[*]

SUBJECTS (PLANNED): 415 subjects

PATIENT POPULATION:

Target population for this study is subjects ≥ 12 years of age with known diagnosis of CF, with history of prior PEx in the last 12 months, [*].

STUDY PRODUCTS, DOSE AND MODE OF ADMINISTRATION

Study drugs are [*] of lenabasum 20 mg, lenabasum 5 mg and placebo.

Lenabasum and placebo capsules are identical in terms of appearance. Both are packaged in the same type container closures with the same number of capsules.

[*].

DURATION OF TREATMENT: 28 weeks

DISCONTINUATION FROM TREATMENT:

Removal of Subjects from Therapy or Assessments:

An individual subject will have study drug permanently discontinued if any of the following occur in the subject in question:

[*].

Premature Termination or Suspension of the Study:

This study may be suspended or prematurely terminated if there is sufficient reasonable cause. If any of the following events occur in a subject during enrollment, study entry and randomization of new subjects into the study will be suspended until review of the event in question occurs by the Data Monitoring Committee (DMC):

Administration of study drug may continue during the time of review in subjects who are already receiving study drug, based on the judgment of the Chief Medical Officer of Corbus.

An expedited and cumulative review of safety data and the circumstances of the event(s) in question will be conducted by the DMC, with additional external expertise as needed, to make recommendations to Corbus whether screening, randomization, and/or dosing can resume or should be discontinued, whether the protocol should be modified, or whether the study should be discontinued permanently. Upon consideration of a cumulative review of safety and other data, the study can be discontinued permanently by Corbus.

Written notification, documenting the reason for study suspension or termination, will be provided by Corbus to the investigators and the respective country regulatory authorities. If the study is suspended or prematurely terminated, the investigators will promptly inform the reviewing Independent Ethics Committee/Institutional Review Board (hereafter referred to as the Ethics Committee or EC) at each site and will provide the reason(s) for the suspension or termination. Review and approval by the reviewing EC at each site is required for resumption of the study in the event the study is interrupted.

CORBUS PHARMACEUTICALS HOLDINGS, INC.

WARRANT TO PURCHASE COMMON STOCK

Corbus Pharmaceuticals Holdings, Inc., a Delaware corporation (the “Company”), for value received on January 26, 2018 (the “Effective Date”), hereby issues to The Cystic Fibrosis Foundation (the “Holder”) this warrant (the “Warrant”) to purchase, 1,000,000 shares (each such share as from time to time adjusted as hereinafter provided being a “Warrant Share” and all such shares being the “Warrant Shares”) of the Company’s Common Stock (as defined below), at the Exercise Price (as defined below), as adjusted from time to time as provided herein, on or before January 26, 2025 (the “Expiration Date”), all subject to the following terms and conditions.

As used in this Warrant, (i) “Business Day” means any day other than Saturday, Sunday or any other day on which commercial banks in the City of New York, New York, are authorized or required by law or executive order to close; (ii) “Common Stock” means the common stock of the Company, par value $0.0001 per share, including any securities issued or issuable with respect thereto or into which or for which such shares may be exchanged for, or converted into, pursuant to any stock dividend, stock split, stock combination, recapitalization, reclassification, reorganization or other similar event; (iii) “Exercise Price” means $13.20 per share of Common Stock, subject to adjustment as provided herein; (iv) “Trading Day” means any day on which the Common Stock is traded (or available for trading) on its principal Trading Market (as defined below); and (v) “Affiliate” means any person that, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, a person, as such terms are used and construed in Rule 144 promulgated under the Securities Act of 1933, as amended (the “Securities Act”). For purposes hereof, “Trading Market” means any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the New York Stock Exchange, the NYSE MKT, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market, or any other national securities exchange, as well as the OTC Bulletin Board or any tier of the OTC Markets.

(a) Exercise Period. Commencing on the Effective Date of this Warrant, the Holder may exercise this Warrant for up to 500,000 shares of Common Stock (the “Initial Exercise Amount”). Upon the Completion of the CF Trial (as defined below), the Holder may exercise this Warrant for the remaining 500,000 shares of Common Stock (the “Additional Exercise Amount”) issuable pursuant to the terms of this Warrant. At no point in time, may the Holder exercise this Warrant for more than 1,000,000 shares of Common Stock in the aggregate. The Holder may exercise this Warrant, in whole or in part (in accordance with the limitations set forth in this Section 1(a)), on any Business Day on or before 5:00 P.M., Eastern Time, on the Expiration Date, at which time this Warrant shall become void and of no value. For purposes of this Warrant, the term “Completion of the CF Trial” shall mean completion of the final Milestone by the Company and receipt of the final Milestone Payment by the Company from Cystic Fibrosis Foundation as set forth in Exhibit B to the Cystic Fibrosis Program Related Investment Agreement by and between Corbus Pharmaceuticals, Inc. and Cystic Fibrosis Foundation dated January 26, 2018.

(b) Exercise Procedures.

(i) While this Warrant remains outstanding and exercisable in accordance with Section 1(a) , the Holder may exercise this Warrant in whole or in part at any time and from time to time by:

(A) delivery to the Company of a duly executed copy of the Notice of Exercise attached as Exhibit A;

(B) surrender of this Warrant to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder; and

(C) payment of the then-applicable Exercise Price per share multiplied by the number of Warrant Shares being purchased upon exercise of the Warrant (such amount, the “Aggregate Exercise Price”) made in the form of cash, or by certified check, bank draft or money order payable in lawful money of the United States of America.

(ii) Upon the exercise of this Warrant in compliance with the provisions of Section 1(a) and this Section 1(b), the Company shall promptly issue and cause to be delivered to the Holder a certificate for the Warrant Shares purchased by the Holder. Each exercise of this Warrant shall be effective immediately prior to the close of business on the date (the “Date of Exercise”) that the conditions set forth in this Section 1(b) have been satisfied, as the case may be. On the first Business Day following the date on which the Company has received each of the Notice of Exercise and the Aggregate Exercise Price (the “Exercise Delivery Documents”), the Company shall transmit an acknowledgment of receipt of the Exercise Delivery Documents to the Company’s transfer agent (the “Transfer Agent”). On or before the second Business Day following the date on which the Company has received all of the Exercise Delivery Documents (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to the address as specified in the Notice of Exercise, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the certificates evidencing such Warrant Shares.

(c) Partial Exercise. This Warrant shall be exercisable, either in its entirety or, from time to time, for part only of the number of Warrant Shares referenced by this Warrant for which the Warrant is then currently exercisable. If this Warrant is submitted in connection with any exercise pursuant to Section 1 and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the actual number of Warrant Shares being acquired upon such an exercise, then the Company shall as soon as practicable after any exercise and at its own expense, issue a new Warrant of like tenor representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised.

(d) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 16.

(a) The Company covenants that all Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be (i) duly authorized, fully paid and non-assessable, and (ii) free from all liens, charges and security interests, with the exception of claims arising through the acts or omissions of any Holder and except as arising from applicable Federal and state securities laws.

(b) The Company shall register this Warrant upon records to be maintained by the Company for that purpose in the name of the record holder of such Warrant from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner thereof for the purpose of any exercise thereof, any distribution to the Holder thereof and for all other purposes.

(c) The Company will not, by amendment of its certificate of incorporation, by-laws or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all action necessary or appropriate in order to protect the rights of the Holder to exercise this Warrant, or against impairment of such rights.

(a) The Exercise Price and the number of shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events described in this Section 3; provided, that notwithstanding the provisions of this Section 3, the Company shall not be required to make any adjustment if and to the extent that such adjustment would require the Company to issue a number of shares of Common Stock in excess of its authorized but unissued shares of Common Stock, less all amounts of Common Stock that have been reserved for issue upon the conversion of all outstanding securities convertible into shares of Common Stock and the exercise of all outstanding options, warrants and other rights exercisable for shares of Common Stock. If the Company does not have the requisite number of authorized but unissued shares of Common Stock to make any adjustment, the Company shall use its commercially reasonable efforts to obtain the necessary stockholder consent to increase the authorized number of shares of Common Stock to make such an adjustment pursuant to this Section 3.

(i) Subdivision or Combination of Stock. In case the Company shall at any time subdivide (whether by way of stock dividend, stock split or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of Warrant Shares, the Initial Exercise Amount and the Additional Exercise Amount shall be proportionately increased, and conversely, in case the outstanding shares of Common Stock of the Company shall be combined (whether by way of stock combination, reverse stock split or otherwise) into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares, the Initial Exercise Amount and the Additional Exercise Amount shall be proportionately decreased. The Exercise Price, the Warrant Shares, the Initial Exercise Amount and the Additional Exercise Amount, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3(a)(i).

(ii) Dividends in Stock, Property, Reclassification. If at any time, or from time to time, all of the holders of Common Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefore:

(A) any shares of stock or other securities that are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution, or

(B) additional stock or other securities or property (including cash) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of Section 3(a)(i) above), then and in each such case, the Exercise Price and the number of Warrant Shares to be obtained upon exercise of this Warrant shall be adjusted proportionately, and the Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to above) that such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3(a)(ii).

(iii) Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or other transaction shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities, or other assets or property (an “Organic Change”), then, as a condition of such Organic Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented by this Warrant) such shares of stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable assuming the full exercise of the rights represented by this Warrant. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of shares purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company will not affect any such consolidation, merger or sale unless, prior to the consummation thereof, the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing such assets shall assume by written instrument reasonably satisfactory in form and substance to the Holder executed and mailed or delivered to the registered Holder hereof at the last address of such Holder appearing on the books of the Company, the obligation to deliver to such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase. If there is an Organic Change, then the Company shall cause to be mailed to the Holder at its last address as it shall appear on the books and records of the Company, at least 10 calendar days before the effective date of the Organic Change, a notice stating the date on which such Organic Change is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares for securities, cash, or other property delivered upon such Organic Change; provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to exercise this Warrant during the 10-day period for the amount of shares of Common Stock for which this Warrant is then currently exercisable commencing on the date of such notice to the effective date of the event triggering such notice. In any event, the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing such assets shall be deemed to assume such obligation to deliver to such Holder such shares of stock, securities or assets even in the absence of a written instrument assuming such obligation to the extent such assumption occurs by operation of law.

(b) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to this Section 3, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall promptly furnish or cause to be furnished to such Holder a like certificate setting forth: (i) such adjustments and readjustments; and (ii) the number of shares and the amount, if any, of other property which at the time would be received upon the exercise of the Warrant.

(c) Certain Events. If any event occurs as to which the other provisions of this Section 3 are not strictly applicable but the lack of any adjustment would not fairly protect the purchase rights of the Holder under this Warrant in accordance with the basic intent and principles of such provisions, or if strictly applicable would not fairly protect the purchase rights of the Holder under this Warrant in accordance with the basic intent and principles of such provisions, then the Company’s Board of Directors will, in good faith, make an appropriate adjustment to protect the rights of the Holder; provided, that no such adjustment pursuant to this Section 3(c) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 3.

(a) Registration of Transfers and Exchanges. Subject to Section 5(c), upon the Holder’s surrender of this Warrant, with a duly executed copy of the Form of Assignment attached as Exhibit B, to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder, the Company shall register the transfer of all or any portion of this Warrant. Upon such registration of transfer, the Company shall issue a new Warrant, in substantially the form of this Warrant, evidencing the acquisition rights transferred to the transferee and a new Warrant, in similar form, evidencing the remaining acquisition rights not transferred, to the Holder requesting the transfer.

(b) Warrant Exchangeable for Different Denominations. The Holder may exchange this Warrant for a new Warrant or Warrants, in substantially the form of this Warrant, evidencing in the aggregate the right to purchase the number of Warrant Shares which may then be purchased hereunder, each of such new Warrants to be dated the date of such exchange and to represent the right to purchase such number of Warrant Shares as shall be designated by the Holder. The Holder shall surrender this Warrant with duly executed instructions regarding such re-certification of this Warrant to the Secretary of the Company at its principal offices or at such other office or agency as the Company may specify in writing to the Holder.

(c) Restrictions on Transfers. This Warrant may not be transferred at any time without: (i) registration under the Securities Act; or (ii) an exemption from such registration and a written opinion of legal counsel addressed to the Company that the proposed transfer of the Warrant may be effected without registration under the Securities Act, which opinion will be in form and from counsel reasonably satisfactory to the Company.

(d) Permitted Transfers and Assignments. Notwithstanding any provision to the contrary in this Section 5, the Holder may transfer, with or without consideration, this Warrant or any of the Warrant Shares (or a portion thereof) to the Holder’s Affiliates without obtaining the opinion from counsel that may be required by Section 5(c)(ii), provided, that the Holder delivers to the Company and its counsel certification, documentation, and other assurances reasonably required by the Company’s counsel to enable the Company’s counsel to render an opinion to the Company’s Transfer Agent that such transfer does not violate applicable securities laws.

If this Warrant is mutilated, lost, stolen or destroyed, upon request by the Holder, the Company will, at its expense, issue, in exchange for and upon cancellation of the mutilated Warrant, or in substitution for the lost, stolen or destroyed Warrant, a new Warrant, in substantially the form of this Warrant, representing the right to acquire the equivalent number of Warrant Shares; provided, that, as a prerequisite to the issuance of a substitute Warrant, the Company may require satisfactory evidence of loss, theft or destruction as well as an indemnity from the Holder of a lost, stolen or destroyed Warrant.

The Company will pay all transfer and stock issuance taxes attributable to the preparation, issuance and delivery of this Warrant and the Warrant Shares (and replacement Warrants) including, without limitation, all documentary and stamp taxes; provided, however, that the Company shall not be required to pay any tax in respect of the transfer of this Warrant, or the issuance or delivery of certificates for Warrant Shares or other securities in respect of the Warrant Shares to any person or entity other than to the Holder.

No fractional Warrant Shares shall be issued upon exercise of this Warrant. The Company, in lieu of issuing any fractional Warrant Share, shall round up the number of Warrant Shares issuable to nearest whole share.

No holder of this Warrant, as such, shall be entitled to vote or be deemed the holder of any other securities of the Company that may at any time be issuable on the exercise hereof, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, the rights of a stockholder of the Company or the right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any corporate action or to receive notice of meetings or other actions affecting stockholders (except as provided herein), or to receive dividends or subscription rights or otherwise (except as provide herein).

Each certificate for Warrant Shares initially issued upon the exercise of this Warrant, and each certificate for Warrant Shares issued to any subsequent transferee of any such certificate, shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY STATE SECURITIES LAWS, AND NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH REGISTRATION EXISTS AND THE COMPANY RECEIVES AN OPINION OF COUNSEL TO THE HOLDER OF SUCH SECURITIES, WHICH COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR APPLICABLE STATE SECURITIES LAWS.”

Any Warrant Shares acquired pursuant to an exercise of this Warrant must not be transferred, sold, hypothecated or otherwise disposed for a period of one year from the date on which the Share Delivery Date .

All notices, consents, waivers, and other communications under this Warrant must be in writing and will be deemed given to a party when (a) delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid); (b) sent by facsimile or e-mail with confirmation of transmission by the transmitting equipment; (c) received or rejected by the addressee, if sent by certified mail, return receipt requested, if to the registered Holder hereof; or (d) seven (7) days after the placement of the notice into the mails (first class postage prepaid), to the Holder at the address, facsimile number, or e-mail address furnished by the registered Holder to the Company in accordance with the Subscription Agreement by and between the Company and the Holder, or if to the Company, to it at One Kendall Square, Bldg 200, Cambridge, MA 02139, Attn: Yuval Cohen, CEO (or to such other address, facsimile number, or e-mail address as the Holder or the Company as a party may designate by notice the other party).

If a court of competent jurisdiction holds any provision of this Warrant invalid or unenforceable, the other provisions of this Warrant will remain in full force and effect. Any provision of this Warrant held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

This Warrant shall be binding upon and inure to the sole and exclusive benefit of the Company, its successors and assigns, the registered Holder or Holders from time to time of this Warrant and the Warrant Shares.

This Warrant shall terminate and be of no further force and effect on the earlier of 5:00 P.M., Eastern Time, on the Expiration Date or the date on which this Warrant has been exercised in full.

This Warrant will be governed by and construed under the laws of the State of New York without regard to conflicts of laws principles that would require the application of any other law.

In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Notice of Exercise giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three Business Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two Business Days, submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

Upon (a) any establishment by the Company of a record date of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or right or option to acquire securities of the Company, or any other right; or (b) any capital reorganization, reclassification, recapitalization, merger or consolidation of the Company with or into any other corporation, any transfer of all or substantially all the assets of the Company, or any voluntary or involuntary dissolution, liquidation or winding up of the Company, or the sale, in a single transaction, of a majority of the Company’s voting stock (whether newly issued, or from treasury, or previously issued and then outstanding, or any combination thereof), the Company shall mail to the Holder at least ten (10) Business Days, or such longer period as may be required by law, prior to the record date specified therein, a notice specifying; (i) the date established as the record date for the purpose of such dividend, distribution, option or right and a description of such dividend, option or right; (ii) the date on which any such reorganization, reclassification, transfer, consolidation, merger, dissolution, liquidation or winding up, or sale is expected to become effective;and (iii) the date, if any, fixed as to when the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reorganization, reclassification, transfer, consolation, merger, dissolution, liquidation or winding up.

The Company shall reserve and keep available out of its authorized but unissued shares of Common Stock for issuance upon the exercise of this Warrant, free from pre-emptive rights, such number of shares of Common Stock for which this Warrant shall from time to time be exercisable. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation. Without limiting the generality of the foregoing, the Company covenants that it will use commercially reasonable efforts to take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and use commercially reasonable efforts to obtain all such authorizations, exemptions or consents, including but not limited to consents from the Company’s stockholders or Board of Directors or any public regulatory body, as may be necessary to enable the Company to perform its obligations under this Warrant.

This Warrant is not intended, and will not be construed, to create any rights in any parties other than the Company and the Holder, and no person or entity may assert any rights as third-party beneficiary hereunder.
