The Licensor and Lung Therapeutics, Inc. entered into a Patent License Agreement (UTA Agreement No. PM1504101-A) with an Effective Date of July 8, 2015, which was assigned by Lung Therapeutics, Inc. to Licensee on January 24, 2018 and consented to by Licensor on March 9, 2018, and was amended by Amendment #1 to the Patent License Agreement with an effective date of November 30, 2018, by Amendment # 2 to the Patent License Agreement with an effective date of September 6, 2019, by Amendment #3 to the Patent License Agreement with an effective date of May 5, 2020, by Amendment #4 to the Patent License Agreement with an effective date of June 12, 2020, by Amendment #5 to the Patent License Agreement with an effective date of July 27, 2020, and further amended by Amendment #6 to the Patent License Agreement with an effective date of November 13, 2020 (as amended, the “Original Patent License Agreement”).

The Licensor and Licensee entered into a second Patent License Agreement (UTA Agreement No. PM1908501) with an Effective Date of August 30, 2019.

The Parties now wish to further amend the Original Patent License Agreement as set forth below and terminate the UTA Agreement No. PM1908501. UTA Agreement PM1908501 terminates automatically upon execution of this Patent License Agreement.

“Milestone Fees” means all fees identified as Milestone Fees in Section 3.1(a) of the Patent License Agreement.

“Phase II” means a human clinical trial of a Licensed Product the principal purpose of which is to make a preliminary determination that such Product is safe in a patient population for its intended use and to obtain sufficient information about such Product's efficacy to permit the design of further clinical trials, and be generally consistent with 21 CFR § 312.21(b). Said trial may be conducted in any country.

“Phase III” means a human clinical trial of a Licensed Product, which trial is designed to: (a) establish that a Licensed Product is safe and efficacious for its intended use; (b) define warnings, precautions and adverse reactions that are associated with the Licensed Product in the dosage range to be prescribed; (c) support regulatory approval of such Licensed Product; and (d) be generally consistent with 21 CFR § 312.21(c).

“Sublicense Fee” means the fee specified in Section 3.1(b) of the Patent License Agreement.

“Sublicensee” means any entity to whom an express sublicense has been granted under the Patent Rights. For clarity, a third party wholesaler or distributor who has no significant responsibility for marketing and promotion of the Licensed Product or Licensed Services within its distribution territory or field (i.e., the third party simply functions as a reseller), and who does not pay any consideration to Licensee or an Affiliate for such wholesale or distributor rights, shall not be deemed a Sublicensee; and the resale by such a wholesaler or distributor shall not be treated as royalty bearing Net Sales by a Sublicensee provided that a royalty is being paid by Licensee for the initial transfer to the wholesaler or distributor pursuant to Section 3.2. This definition does not limit Licensee’s rights to grant or authorize sublicenses under the Agreement.

“Territory” means the territory so indicated as the Territory in Section 1 of the Patent License Agreement.

“Valid Claim” means a claim of (i) an issued and unexpired patent included within the Patent Rights unless the claim has been held unenforceable or invalid by the final, un-reversed, and un-appealable decision of a court or other government body of competent jurisdiction, has been irretrievably abandoned or disclaimed, or has otherwise been finally admitted or determined to be invalid, un-patentable or unenforceable, whether through reissue, reexamination, disclaimer or otherwise, or (ii) a pending patent application within the Patent Rights to the extent the claim continues to be prosecuted in good faith.

(2) Sublicensee’s acknowledgment of the disclaimer of warranty and limitation on Licensor’s liability, as provided by Section 11.3 and 12 below.

(3) Provisions under which the Sublicensee accepts duties at least equivalent to those accepted by the Licensee in the following Sections: Section 11.3 (Licensor Disclaimers); Section 12 (Limitation of Liability); Section 13 (Indemnification); Section 14.1 (Insurance Requirements); Section 17 (Use of Name); and Section 19.10 (Sovereign Immunity, if applicable).

(e) Licensee shall deliver to Licensor a true, complete, and correct copy of each Sublicense Agreement granted by Licensee, Affiliate or Sublicensee, and any modification or termination thereof, within 30 days following the applicable execution, modification, or termination of such Sublicense Agreement. If the Sublicense Agreement is not in English, Licensee shall provide Licensor an accurate English translation in addition to a copy of the original agreement.

(f) Notwithstanding any such Sublicense Agreement, Licensee will remain primarily liable to Licensor for all of the Licensee’s duties and obligations contained in the Agreement, including without limitation the payment of running royalties due under Section 3.2 whether or not paid to Licensee by a Sublicensee. Any act or omission of a Sublicensee that would be a breach of the Agreement if performed by Licensee will be deemed to be a breach by Licensee unless Licensee complies with the remaining provisions of this paragraph. Each Sublicense Agreement will contain a right of termination by Licensee in the event that the Sublicensee breaches the payment or reporting obligations affecting Licensor or any other terms and conditions of the Sublicense Agreement that would constitute a breach of the Agreement if such acts were performed by Licensee. In the event of a Sublicensee breach, and if after a reasonable opportunity to cure as provided in any such Sublicense Agreement, such Sublicensee fails to cure such Sublicensee breach, then the Licensee shall in Licensee’s discretion either terminate the Sublicense Agreement or shall continue to be responsible for all payments and reports owed to Licensor as a result of Sublicensee’s activities under such Sublicense Agreement.

(g) If a Sublicensee initiates any proceeding or action to challenge the validity, enforceability, or scope of one or more of the Patent Rights, Licensor shall provide written notice of such action to Licensee, and Licensee shall immediately terminate such Sublicense.

5. Payment, Records, and Audits

5.1 Payments

All amounts referred to in the Patent License Agreement are expressed in U.S. dollars without deductions for taxes, assessments, fees, or charges of any kind. Each payment will reference the agreement number set forth at the beginning of the Patent License Agreement. All payments to Licensor will be made in U.S. dollars by check or wire transfer (Licensee to pay all wire transfer fees) payable to the payee identified in Section 18 of the Patent License Agreement and sent to the payment and reporting contact in Section 18 (Notices) of the Patent License Agreement.

5.2 Sales Outside the U.S.

If any currency conversion shall be required in connection with the calculation of payments hereunder, such conversion shall be made using the rate used by Licensee for its financial reporting purposes in accordance with Generally Accepted Accounting Principles (or foreign equivalent) or, in the absence of such rate, using the average of the buying and selling exchange rate for conversion between the foreign currency and U.S. Dollars, for current transactions as reported in The Wall Street Journal on the last business days of the Contract Quarter to which such payment pertains. Licensee may not make any tax withholdings from payments to Licensor, but Licensor agrees to supply to Licensee, upon written request, appropriate evidence from appropriate U.S. governmental agencies showing that Licensor is a resident of the United States of America for purposes of the U.S. income tax laws and is tax-exempt under such income tax laws.

5.3 Late Payments

Amounts that are not paid when due will accrue a late charge from the due date until the date paid, at a rate equal to 1.0% per month (or the maximum allowed by law, if less).

5.4 Records

For a period of six years after the Contract Quarter to which the records pertain, Licensee agrees that it and its Affiliates and Sublicensees will each keep complete and accurate records of their Sales, Net Product Sales, Net Service Sales, Milestone Fees, and Non-Royalty Sublicensing Consideration in sufficient detail to enable such payments to be determined and audited.

5.5 Auditing

Licensee and its Affiliates will permit Licensor or its representatives, at Licensor’s expense, to annually examine books, ledgers, and records during regular business hours, at Licensee’s or its Affiliate’s place of business, on at least 30 days advance written notice, to the extent necessary to verify any payment or report required under the Agreement. For each Sublicensee, Licensee shall obtain such audit rights for itself, and will, within 30 days of Licensor’s written request, conduct an audit of the Sublicensee’s records, and Licensee will furnish to Licensor a copy of the findings from such audit. No more than one audit of Licensee, each Affiliate, and each Sublicensee shall be conducted under this Section 5.5 in any calendar year. If any amounts due Licensor have been underpaid, then Licensee shall immediately pay Licensor the amount of such underpayment plus accrued interest due in accordance with Section 5.3. If the amount of underpayment is equal to or greater than 5% of the total amount due for the records so examined, Licensee will pay the cost of such audit. Such audits may, at Licensor’s sole discretion, consist of a self-audit conducted by Licensee at Licensee’s expense and certified in writing by an authorized officer of Licensee. All information examined pursuant to this Section 5.5 shall be deemed to be the Confidential Information of the Licensee.

6. Patent Expenses and Prosecution

6.1 Patent Expenses

Licensee shall pay for all past documented, out-of-pocket expenses incurred by Licensor for filing, prosecuting, enforcing, defending and maintaining Patent Rights and related patent searches through the Effective Date of the Agreement. Licensee shall pay all expenses incurred by Licensor for actions instructed or approved by Licensee, or that are otherwise necessary for the maintenance of the Patent Rights after the effective date, for so long as, and in such countries as the Agreement remains in effect. Licensee will pay all patent expenses within 30 days after Licensee’s receipt of an invoice. Patent expense payment delinquencies (whether owed directly to Prosecution Counsel or to Licensor) will be considered a payment default under Section 7.3(a).

6.2 Direction of Prosecution

Licensor will confer with Licensee to develop a strategy for the prosecution and maintenance of Patent Rights. Licensor will request that copies of all documents prepared by the Prosecution Counsel for submission to governmental patent offices be provided to Licensee for review and comment prior to filing. At its discretion, Licensor may allow Licensee to instruct Prosecution Counsel directly, provided, that (a) Licensor will maintain final authority in all decisions regarding the prosecution and maintenance of the Patent Rights, (b) Licensor may revoke this authorization to instruct Prosecution Counsel directly at any time, and (c) the Prosecution Counsel remains counsel to the Licensor with an appropriate contract (and shall not jointly represent Licensee unless requested by Licensee and approved by Licensor, and an appropriate engagement letter and conflict waiver are in effect). If Licensee wishes to instruct Prosecution Counsel directly or change Prosecution Counsel, Licensee may request to do so by following the Licensor’s procedures for such. Licensor reserves in its sole discretion the ability to change Prosecution Counsel and to approve or disapprove any requested changes by Licensee. The Parties agree that they share a common legal interest to get valid enforceable patents and that Licensee will maintain as privileged all information received pursuant to this Section.

6.3 Ownership

The ownership of all patent applications and patents filed after the effective date will be determined in accordance with U.S. patent law. No payments due under the Agreement will be reduced as the result of co-ownership interests in the Patent Rights by Licensee or any other party.

Licensee: TFF Pharmaceuticals, Inc.	CONFIDENTIAL	Amended and Restated Patent License Agreement
The University of Texas at Austin	Page A-11 of 37	Agreement No. PM2202501

6.4 Foreign Filings

In addition to the U.S., the Patent Rights shall, subject to applicable bar dates, be pursued in such foreign countries as Licensee so designates in writing to Licensor in sufficient time to reasonably enable the preparation of such additional filings, and in those foreign countries in which Licensor has filed applications prior to the Effective Date. If Licensee does not choose to pursue patent rights in a particular foreign country and Licensor chooses to do so, Licensor shall provide written notice to Licensee and thereafter said patent application or patent shall no longer be included in the Patent Rights and Licensee shall have no further rights thereto. Licensor shall have the right to make alternative arrangements with Licensee for upfront payment of foreign patent expenses.

6.5 Withdrawal from Paying Patent Costs

If at any time Licensee wishes to cease paying for any costs for any particular Patent Rights or for patent prosecution in a particular jurisdiction, Licensee must give Licensor at least 90 days prior written notice (the “Notice Period”) and Licensee will continue to be obligated to pay for the patent costs which reasonably accrue during said Notice Period. Thereafter, said patent application or patent shall no longer be included in the Patent Rights and Licensee shall have no further rights thereto.

6.6 U.S. Patent and Trademark Office Entity Size Status

Licensee represents that as of the Effective Date the entity size status of Licensee in accordance with the regulations of the U.S. Patent and Trademark Office is as set forth in Section 1 of the Patent License Agreement. Licensee will inform Licensor in writing on a timely basis of any change in its U.S. Patent and Trademark Office entity size status.

6.7 Extension of Patent Term

If a Licensed Product is eligible for extending the term of any patent in the Patent Rights under the Drug Price Competition and Patent Term Restoration Act of 1984 and/or any European, Japanese, or other foreign counterparts of this law, then Licensee shall take all necessary steps with the appropriate regulatory authorities to apply in a timely manner for such an extension of the term for such patent. For example, such application must be made to the USPTO within sixty (60) days after the US FDA approves a commercial marketing application for said Licensed Product. Licensee shall prepare and file all documents needed for the application; and Licensee shall take all reasonable actions as may be appropriate to further obtain patent term extension. Licensor shall cooperate and sign such documents as may be reasonably requested by Licensee for the application.

Licensee shall keep Licensor informed as to Licensee’s efforts to prepare and file said application, including giving a written report within thirty (30) days after Licensee obtains the applicable marketing approval from the FDA (or foreign counterpart). If Licensee fails to make this required application, then Licensor shall have the option but not the obligation to do so; and if Licensor does elect to file the application, then Licensee shall cooperate and sign such documents as may be needed; and Licensee shall reimburse Licensor’s costs incurred for said application.

EXHIBIT C

Niclosamide Diligence Milestones

Licensee by itself or through its Affiliates and Sublicensees will use diligent efforts to make commercially available products or services that practice an issued or pending claim of any patent or application listed under or claiming priority from an application listed under UT Tech ID 7574 WIL in the Patent Rights in Exhibit B, for example, oral or inhaled formulations of niclosamide (“Niclosamide Products”). Without limiting the foregoing, Licensee will (a) maintain a reasonably funded, ongoing and active research, development, manufacturing, regulatory, marketing or sales program required to make Niclosamide Products commercially available, and (b) by itself or through its Affiliates and Sublicensees fulfill the Niclosamide Milestone Events specified in this Exhibit C and (c) use diligent and commercially reasonable efforts to perform and complete the plans described in the annual report submitted pursuant to Section 4.2 (Annual Written Progress Report). If the obligations under this Exhibit C are not fulfilled, Licensor may treat such failure as a breach in accordance with Section 7.3(b), provided however if the breach is a result of not meeting the Niclosamide Milestone Events specified in this Exhibit C, Licensor will work in good faith with Licensee to cure such breach by amending the PLA to change the Field of the exclusive license to Patent Rights based on UT Tech ID 7574 WIL from “All fields” to “dry powders manufactured by thin film freezing or ultra-rapid freezing technology.”

With regard to the Niclosamide Milestone Events specified in this Exhibit C, Licensee may at its election, extend the target date for fulfillment of such milestone events by twelve (12) months upon written notice to Licensor and payment to Licensor of an amount equal to $10,000. Licensee may invoke this clause only one time.

If Licensee sublicenses Patent Rights for the development of Niclosamide Products, and Sublicensee develops an alternate development plan within 24 months of Amendment Effective Date, Licensor will renegotiate Niclosamide Milestone Events in good faith according to Sublicensee’s reasonable timeline.

The University of Texas at Austin	Page C-1 of 37	Agreement No. PM2202501

If Licensor or a third party discovers that the Niclosamide Products are useful for an application for which Products have not been developed or are not currently under development by Licensee by itself or through its Affiliates and Sublicensees, then Licensor shall give written notice to the Licensee, except for information that is subject to restrictions of confidentiality with third parties.

Within ninety (90) days following Licensee’s receipt of Licensor’s notification, Licensee shall give Licensor written notice stating whether Licensee elects to develop Niclosamide Products for the application. If Licensee elects to develop and commercialize the proposed Niclosamide Products for the new application, Licensee shall provide Licensor with a commercial development plan for the new application, including proposed commercial milestones. Licensor and Licensee shall negotiate in good faith new diligence milestones for such application, which shall be added to this Agreement by amendment.

If Licensee elects not to develop and commercialize the proposed Niclosamide Products for use in the new application, Licensor may seek third parties to develop and commercialize the proposed Niclosamide Products for the new application.
