1.4 “KNOW-HOW AND MATERIALS” shall mean JHU’s interest in proprietary materials, information, records, and data developed by [**] (including incidental information developed in his laboratory) and at his direction by his laboratory personnel, fellows, and students and that are directly related to the use of and practice of the PATENT RIGHTS, and are (a) subject to the ▇▇▇▇▇ ▇▇▇▇▇▇▇ Intellectual Property Policy and (b) owned by JHU as of the EFFECTIVE DATE or developed within [**] years from the EFFECTIVE DATE and not subject to any third party rights, including without limitation the materials listed on Exhibit C. Know-How specifically excludes patentable inventions.

1.5 “LICENSED FIELD” shall mean all fields of use.

1.6 “LICENSED PRODUCT(S)” as used herein in either singular or plural shall mean any process or method, material, compositions, drug, or other product, the manufacture, use or sale of which would constitute, but for the license granted to Company pursuant to this Agreement, an infringement of a VALID CLAIM of PATENT RIGHTS (infringement shall include, but is not limited to, direct, contributory, or inducement to infringe) in the country of sale.

1.7 “LICENSED SERVICE(S)” as used herein in either singular or plural shall mean the performance on behalf of a third party of any method or the manufacture of any product or the use of any product or composition which would constitute, but for the license granted to Company pursuant to this Agreement, an infringement of a VALID CLAIM of the PATENT RIGHTS, (infringement shall include, but not be limited to, direct, contributory or inducement to infringe) in the country of performance of the services.

1.8 “NET SALES” shall mean gross sales revenues and fees billed by Company and AFFILIATED COMPANY from the sale of LICENSED PRODUCT(S) less (i) trade, quantity or cash discounts allowed, (ii) refunds, credits or allowances for returns, rejections and recalls; (iii) rebates and chargebacks, (iv) sales, use or other taxes and tariffs, duties or other charges levied by a governmental entity on the production, sale, delivery or use of LICENSED PRODUCT(S), and (iv) packing, freight, shipping and insurance charges.

In the event that Company or AFFILIATED COMPANY sells a LICENSED PRODUCT(S) as part of a combination, then:

(i) in the event that Company or AFFILIATED COMPANY sells in a particular country during a particular year a LICENSED PRODUCT(S) together with other non-therapeutic ingredients or substances or as part of a kit, and Company or AFFILIATED COMPANY also sells such LICENSED PRODUCT(S) in such country in such year separately the NET SALES for purposes of royalty payments shall be based on the sales revenues and fees that would be received from the separate sale of the same quantity of LICENSED PRODUCT as is contained in the combination.

(ii) in the event that Company or an AFFILIATED COMPANY sells, in a particular country during a particular year, a LICENSED PRODUCT for therapeutic purposes in combination with a therapeutically active ingredient which is not a LICENSED PRODUCT (“Other Items”), the NET SALES for purposes of royalty payments shall be calculated as follows:

(a) If all LICENSED PRODUCTS and Other Items contained in the combination are available separately in the particular country during such year, the NET SALES for purposes of royalty payments will be calculated by multiplying the NET SALES of the combination by the fraction A/A+B, where A is the separately available price of all LICENSED PRODUCTS in the combination in the particular country during such year, and B is the separately available price for all Other Items in the combination in the particular country during such year.

(b) If the combination includes Other Items which are not sold separately in the particular country during such year (but all LICENSED PRODUCTS contained in the combination are available separately in the particular country during such year), the NET SALES for purposes of royalty payments will be calculated by multiplying the NET SALES of the combination by A/C, where A is as defined above and C is the invoiced price of the combination.

ARTICLE 4
PATENT PROSECUTION, MAINTENANCE, & INFRINGEMENT

4.1 Prosecution & Maintenance. JHU, at Company’s expense, shall file, prosecute and maintain all patents and patent applications specified under PATENT RIGHTS and, subject to the terms and conditions of this Agreement, Company shall be licensed thereunder. Title to all such patents and patent applications shall reside in JHU. JHU shall have full and complete control over all patent matters in connection therewith under the PATENT RIGHTS, provided however, that JHU shall (a) cause its patent counsel to timely copy Company on all official actions and written correspondence with any patent office, and (b) allow Company an opportunity to comment and advise JHU. JHU shall consider and reasonably incorporate all comments and advice unless

detrimental to JHU’s intellectual property rights. By concurrent written notification to JHU and its patent counsel at least [**] days in advance (or later at JHU’s discretion) of any filing or response deadline, or fee due date, Company may elect not to have a patent application filed in any particular country or not to pay expenses associated with prosecuting or maintaining any patent application or patent, provided that Company pays for all costs incurred up to JHU’s receipt of such notification. Failure to provide such notification can be considered by JHU to be Company’s authorization to proceed at Company’s expense. Upon such notification, JHU may file, prosecute, and/or maintain such patent applications or patent at its own expense and for its own benefit, and any rights or license granted hereunder held by Company, AFFILIATED COMPANIES or SUBLICENSEE(S) relating to the PATENT RIGHTS which comprise such patent applications or patent and/or apply to the particular country, shall terminate.

4.2 Notification. Each party will notify the other promptly in writing when any infringement by another is uncovered or suspected.

4.3 Infringement. Company shall have the first right to enforce any patent within PATENT RIGHTS against any infringement or alleged infringement thereof, and shall at all times keep JHU informed as to the status thereof. Before Company commences an action with respect to any infringement of such patents, Company shall give careful consideration to the views of JHU and to potential effects on the public interest in making its decision whether or not to ▇▇▇. Thereafter, Company may, at its own expense, institute suit against any such infringer or alleged infringer and control and defend such suit in a manner consistent with the terms and provisions hereof and recover any damages, awards or settlements resulting therefrom, subject to Paragraph 4.5. If required by law, JHU shall permit action under this Section to be brought in its name, including being joined as party-plaintiff. However, no settlement, consent judgment or other voluntary final disposition of the suit that concedes the invalidity or unenforceability of any patent within PATENT RIGHTS may be entered into without the prior written consent of JHU, which consent shall not be unreasonably withheld. This right to ▇▇▇ for infringement shall not be used in an arbitrary or capricious manner. JHU shall reasonably cooperate in any such litigation at Company’s expense.

If Company elects not to enforce any patent within the PATENT RIGHTS, then it shall so notify JHU in writing within [**] days of receiving notice that an infringement exists, and JHU may, in its sole judgment and at its own expense, take steps to enforce any patent and control, settle, and defend such suit in a manner consistent with the terms and provisions hereof, and recover, for its own account, any damages, awards or settlements resulting therefrom. However, no settlement, consent judgment or other voluntary final disposition of the suit that concedes the invalidity or unenforceability of any patent within PATENT RIGHTS may be entered into without the prior written consent of Company, which consent shall not be unreasonably withheld.

4.4 Patent Invalidity Suit. If a declaratory judgment action is brought naming Company as a defendant and alleging invalidity of any of the PATENT RIGHTS, JHU may elect to take over the sole defense of the action at its own expense. Company shall cooperate fully with JHU in connection with any such action.

4.5 Recovery. Any recovery by Company under Paragraph 4.3 shall be deemed to reflect loss of commercial sales, and Company shall pay to JHU [**] percent ([**]%) of the

recovery, net of all reasonable costs and expenses associated with each suit or settlement. If the cost and expenses exceed the recovery, then [**] of the excess shall be credited against royalties payable by Company to JHU hereunder in connection with sales of LICENSED PRODUCT covered in the PATENT RIGHTS which are the subject of the infringement suit, in the country of such legal proceedings, provided, however, that any such credit under this Paragraph shall not exceed [**] percent ([**]%) of the royalties otherwise payable to JHU with regard to sales in the country of such action in any one calendar year, with any excess credit being carried forward to future calendar years.

4.6 Cooperation. Each party agrees to cooperate in any action under this Article which is controlled by the other party, provided that the controlling party reimburses the cooperating party promptly for any costs and expenses incurred by the cooperating party in connection with providing such assistance.

ARTICLE 5

ARTICLE 6
REPRESENTATIONS

6.1 Duties of the Parties. JHU is not a commercial organization. It is an institute of research and education. Therefore, JHU has no ability to evaluate the commercial potential of any PATENT RIGHTS or LICENSED PRODUCT or other license or rights granted in this Agreement. It is therefore incumbent upon Company to evaluate the rights and products in question, to examine the materials and information provided by JHU, and to determine for itself the validity of any PATENT RIGHTS, its freedom to operate, and the value of any LICENSED PRODUCTS or LICENSED SERVICES or other rights granted.

6.2 Representations by JHU. JHU warrants that it has good and marketable title to its interest in the inventions claimed under PATENT RIGHTS with the exception of certain retained rights of the United States Government, which may apply if any part of the JHU research was funded in whole or in part by the United States Government. JHU does not warrant the validity of any patents or that practice under such patents shall be free of infringement. EXCEPT AS EXPRESSLY SET FORTH IN THIS PARAGRAPH 6.2, COMPANY, AFFILIATED COMPANIES AND SUBLICENSEE(S) AGREE THAT THE PATENT RIGHTS ARE PROVIDED “AS IS”, AND THAT JHU MAKES NO REPRESENTATION OR WARRANTY WITH RESPECT TO THE PERFORMANCE OF LICENSED PRODUCT(S) AND LICENSED SERVICE(S) INCLUDING THEIR SAFETY, EFFECTIVENESS, OR COMMERCIAL VIABILITY. JHU DISCLAIMS ALL WARRANTIES WITH REGARD TO PRODUCT(S) AND SERVICE(S) LICENSED UNDER THIS AGREEMENT, INCLUDING, BUT NOT LIMITED TO, ALL WARRANTIES, EXPRESSED OR IMPLIED, OF MERCHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, JHU ADDITIONALLY DISCLAIMS ALL OBLIGATIONS AND LIABILITIES ON THE PART OF JHU AND INVENTORS, FOR DAMAGES, INCLUDING, BUT NOT LIMITED TO, DIRECT, INDIRECT, SPECIAL, AND CONSEQUENTIAL DAMAGES, ATTORNEYS’ AND EXPERTS’ FEES, AND COURT COSTS (EVEN IF JHU HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, FEES OR COSTS), ARISING OUT OF OR IN CONNECTION WITH THE MANUFACTURE, USE, OR SALE OF THE PRODUCT(S) AND SERVICE(S) LICENSED UNDER THIS AGREEMENT. COMPANY, AFFILIATED COMPANIES AND SUBLICENSEE(S) ASSUME ALL RESPONSIBILITY AND LIABILITY FOR LOSS OR DAMAGE CAUSED BY A PRODUCT AND/OR SERVICE MANUFACTURED, USED, OR SOLD BY COMPANY, ITS SUBLICENSEE(S) AND AFFILIATED COMPANIES WHICH IS A LICENSED PRODUCT(S) OR LICENSED SERVICE(S) AS DEFINED IN THIS AGREEMENT.

6.3 Prior Assignment of Rights. The Parties acknowledge the Assignment of Rights Agreement dated December 8, 2005 among JHU, [**] (the “Assignment Agreement”). JHU agrees (i) that as between JHU on the one hand and [**] on the other hand, [**] are the absolute owners of the patent rights that are the subject of the Assignment Agreement, and JHU will not exercise any right it may have to terminate said Assignment Agreement, (ii) JHU is not entitled to receive any part of any stock in the Company issued to [**], and (iii) the Company will not be obligated to make any payment (including without limitation, royalties and milestones) to JHU with respect to the patent assigned under the Assignment Agreement.

ARTICLE 7
INDEMNIFICATION

7.1 Indemnification. JHU and the Inventors would have no legal liability exposure to third parties if JHU did not license the LICENSED PRODUCT(S) and LICENSED SERVICE(S), and any royalties JHU and the Inventors may receive is not adequate compensation for such legal liability exposure. Therefore, JHU requires Company to protect JHU and Inventors from such exposure to the same manner and extent to which insurance, if available, would protect JHU and Inventors. Furthermore, JHU and the Inventors will not, under the provisions of this Agreement or otherwise, have control over the manner in which Company or its AFFILIATED COMPANIES or its SUBLICENSEE(S) or those operating for its account or third parties who purchase LICENSED PRODUCT(S) or LICENSED SERVICE(S) from any of the foregoing entities, develop, manufacture, market or practice the inventions of LICENSED PRODUCT(S) and LICENSED SERVICE(S). Therefore, Company, AFFILIATED COMPANY and SUBLICENSEE, each solely with respect to its own practice of such inventions, shall indemnify, defend with counsel reasonably acceptable to JHU, and hold JHU, The ▇▇▇▇▇ ▇▇▇▇▇▇▇ Health Systems, their present and former trustees, officers, Inventors of PATENT RIGHTS, agents, faculty, employees and students harmless as against any judgments, fees, expenses, or other costs arising from or incidental to any product liability or other lawsuit, claim, demand or other action brought as a consequence of its own practice of said inventions, whether or not JHU or said Inventors, either jointly or severally, is named as a party defendant in any such lawsuit and whether or not JHU or the Inventors are alleged to be negligent or otherwise responsible for any injuries to persons or property. Practice of the inventions covered by LICENSED PRODUCT(S) and LICENSED SERVICE(S), by an AFFILIATED COMPANY, SUBLICENSEE, or an agent or a third party on behalf of or for the account of Company or by a third party who purchases LICENSED PRODUCT(S) and LICENSED SERVICE(S) from Company, shall be considered Company’s practice of said inventions for purposes of this Paragraph. The obligation of Company to defend and indemnify as set out in this Paragraph shall survive the termination of this Agreement, shall continue even after assignment of rights and responsibilities to an affiliate or sublicensee, and shall not be limited by any other limitation of liability elsewhere in this Agreement.

ARTICLE 8
CONFIDENTIALITY

8.1 Confidentiality. If necessary, the parties will exchange information, which they consider to be confidential. The recipient of such information agrees to accept the disclosure of said information which is marked as confidential at the time it is sent to the recipient, and to employ all reasonable efforts to maintain the information secret and confidential, such efforts to be no less than the degree of care employed by the recipient to preserve and safeguard its own confidential information, and in any event no less than a reasonable degree of care. The information shall not be disclosed or revealed to anyone except employees, consultants, collaborators, investors and prospective investors of the recipient who have a need to know the information and who have entered into a secrecy agreement with the recipient under which such employees are required to maintain confidential the proprietary information of the recipient and such employees shall be advised by the recipient of the confidential nature of the information and that the information shall be treated accordingly.

The obligations of this Paragraph 8.1 shall also apply to AFFILIATED COMPANIES and/or SUBLICENSEE(S) provided such information of JHU by Company. JHU’s, Company’s, AFFILIATED COMPANIES, and SUBLICENSEES’ obligations under this Paragraph 8.1 shall extend until [**] years after the termination of this Agreement.

8.2 Exceptions. The recipient’s obligations under Paragraph 8.1 shall not extend to any part of the information:

a. that can be demonstrated to have been in the public domain or publicly known and readily available to the trade or the public prior to the date of the disclosure; or

b. that can be demonstrated, from written records to have been in the recipient’s possession or readily available to the recipient from another source not under obligation of secrecy to the disclosing party prior to the disclosure; or

c. that becomes part of the public domain or publicly known by publication or otherwise, not due to any unauthorized act by the recipient; or

d. that is demonstrated from written records to have been developed by or for the receiving party without reference to confidential information disclosed by the disclosing party.

e. that is required to be disclosed by law, government regulation or court order.

8.3 Right to Publish. JHU may publish manuscripts, abstracts or the like describing the PATENT RIGHTS and inventions contained therein provided confidential information of Company as defined in Paragraph 8.1, is not included or without first obtaining approval from Company to include such confidential information. Otherwise, JHU and the Inventors shall be free to publish manuscripts and abstracts or the like directed to the work done at JHU related to the licensed technology without prior approval.

ARTICLE 9
TERM & TERMINATION

9.1 Term. The term of this Agreement shall commence on the EFFECTIVE DATE and shall continue, in each country, until the date of expiration of the last to expire patent included within PATENT RIGHTS in that country or if no patents issue then for a term of twenty (20) years from the EFFECTIVE DATE of this Agreement.

9.2 Termination By Either Party. This Agreement may be terminated by either party, in the event that the other party (a) files or has filed against it a petition under the Bankruptcy Act that is not dismissed within [**] days, makes an assignment for the benefit of creditors, has a receiver appointed for it or a substantial part of its assets and such receivership is not terminated within [**] days, or otherwise takes advantage of any statute or law designed for relief of debtors or (b) fails to perform or otherwise breaches any of its obligations hereunder, if, following the giving of notice by the terminating party of its intent to terminate and stating the grounds therefor, the party receiving such notice shall not have cured the failure or breach within [**] days; provided, however, that, except where the alleged breach is for failure to pay a fixed amount due

under this agreement (such as the License Fee, Minimum Annual Royalty or the $[**] monthly patent cost reimbursement payment set forth in Section 3.6), in the event the party receiving the notice disputes the alleged failure to perform or breach in good faith, such [**] day cure period shall commence upon determination by a court of competent jurisdiction (or arbitrator if the parties agree to arbitrate the matter) that the alleged failure to perform or breach exists. In no event, however, shall such notice or intention to terminate be deemed to waive any rights to damages or any other remedy which the party giving notice of breach may have as a consequence of such failure or breach.

9.3 Termination by Company. Company may terminate this Agreement and the license granted herein, for any reason, upon giving JHU ninety (90) days written notice. Company may terminate its license with respect to any particular patent or patent application with 60 days’ notice to JHU and Exhibit D shall be considered amended accordingly. Company will not be required to reimburse JHU for patent costs incurred after the 60-day notice period for such patents or patent applications.

9.4 Obligations and Duties upon Termination. If this Agreement is terminated, both parties shall be released from all obligations and duties imposed or assumed hereunder to the extent so terminated, except as expressly provided to the contrary in this Agreement. Upon termination, both parties shall cease any further use of the confidential information disclosed to the receiving party by the other party. Termination of this Agreement, for whatever reason, shall not affect the obligation of either party to make any payments for which it is liable prior to or upon such termination. Termination shall not affect JHU’s right to recover unpaid royalties, fees, reimbursement for patent expenses, or other forms of financial compensation incurred prior to termination. Upon termination Company shall submit a final royalty report to JHU and any royalty payments, fees, unreimbursed patent expenses and other financial compensation due JHU shall become immediately payable. Furthermore, upon termination of this Agreement, all rights in and to the licensed technology shall revert immediately to JHU at no cost to JHU. Upon termination of this Agreement, any SUBLICENSEE(S) shall become a direct licensee of JHU, provided that JHU’s obligations to SUBLICENSEE(S) are no greater than JHU’s obligations to Company under this Agreement. Company shall provide written notice of such to each SUBLICENSEE(S) with a copy of such notice provided to JHU.

ARTICLE 10

All remedies either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

WHEREAS, ▇▇▇▇▇ NewCo, Inc. changed its name to Kala Pharmaceuticals, Inc. on December 11, 2009.

WHEREAS, the parties wish to amend the Agreement on the terms set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth below, the parties agree as follows:

1. Capitalized terms used herein and not defined herein shall have the respective meanings ascribed to such terms in the Agreement.

2. Each of the parties hereby agrees to amend the agreement to substitute Kala Pharmaceuticals, Inc. in place of ▇▇▇▇▇ NewCo, Inc. every place such name appears in the Agreement.

3. As of the First Amendment Date, Section 2.4 of the Agreement shall be superseded in its entirety by the following:

“Commencing on the First Amendment Date, Company may, within [**] days following the end of a calendar quarter, by email to Director, Technology Licensing [email: [**] or [**]]. request information about any Improvements that were disclosed to the JHU technology transfer office during the previous calendar quarter. Within [**] days after receipt of such email, JHU shall notify Company in writing of any such Improvements; provided, however, that if an invention disclosure describing an Improvement also contains disclosure for one or more additional inventions which are not Improvements (“Other Inventions”), then JHU may redact information on such Other Inventions. Subject to any third party, including U.S. Government, obligations of JHU under any agreement under which any Improvement is made, Company will have a right of first negotiation to amend this Agreement to add the Improvement and related patent rights, know how and materials to this Agreement; provided, that Company notifies JHU of Company’s interest in exercising such right of first negotiation within [**] days after receipt of written notice from JHU of such Improvement. JHU and Company will negotiate in good faith on reasonable terms for adding the Improvement to this Agreement.

6. This First Amendment shall be effective as of the date the last party hereto has executed this First Amendment (the “First Amendment Date”).

7. For the convenience of the parties hereto, this Amendment may be executed in two counterparts, each of which shall be deemed to be an original, but both of which together shall constitute one and the same instrument, without necessity of production of the others. Signatures may be exchanged by facsimile or electronic transmission and each of the parties to this Amendment agrees that it will be bound by its own facsimile signature and that it accepts the facsimile signature of the other party.

8. Amendment Fee. Company shall pay to JHU within [**] days of the First Amendment Date [**] dollars ($[**]) as an amendment fee. JHU will not submit an invoice for the amendment fee, which is nonrefundable and shall not be credited against royalties or other fees.
