After the Closing, the Agent and Landos shall reasonably endeavor to allocate the purchase price for the Acquired Assets, the Licensed Technology and any other assets or property exchanged by Landos in exchange for the Redeemed Shares and the Acquired Compounds License Agreement (as determined for U.S. federal income tax purposes) among the Acquired Assets, the Licensed Technology, and such other assets or property and to agree to a valuation for the Acquired Assets, the Licensed Technology, and such other assets or property. If Landos and the Agent agree to an allocation of the purchase price and to a valuation, no Party shall take a position on any Tax Return (including IRS Form 8594) before any Governmental Entity or in any judicial proceeding that is in any way inconsistent with such allocation without the written consent of the other Party or unless specifically required pursuant to a determination by an applicable Governmental Entity.

At least three (3) Business Days prior to any such deduction or withholding, the withholding party shall provide written notice to the party in respect of which such deduction or withholding is to be made, together with reasonably sufficient details regarding the nature of the relevant Tax to be deducted or withheld. If any valid reduction of or exemption from such Tax is available under applicable Law, the Parties shall use commercially reasonable efforts to cooperate to obtain any such reduction or exemption, including requesting and providing Tax forms and any other information reasonably relevant to obtaining such reduction or exemption. To the extent any Taxes are required to be so deducted or withheld, the Parties and any other applicable withholding agent shall: (i) deduct or withhold such Taxes, (ii) properly remit such Taxes to the appropriate Governmental Entity, and (iii) timely send evidence or proof of Tax payment to the party in respect of which such deduction or withholding was made. Subject to the remainder of this Section 4.13, to the extent any Taxes are so deducted or withheld and properly remitted to the appropriate Governmental Entity, such Taxes shall be treated for all purposes under this Agreement, the Acquired Compounds License Agreement, or the Retained Compounds Royalty Agreement as having been paid to the party in respect of which such deduction or withholding was made. Notwithstanding anything to the contrary herein, if any Party (or any of its Affiliates or assignees, including any Buyer Transferee) is required by applicable Law to deduct or withhold any Taxes from any amounts payable or otherwise deliverable pursuant to this Agreement, the Acquired Compounds License Agreement, or the Retained Compounds Royalty Agreement and if such obligation arises or is increased solely as a result of any action by such Party (or any of its Affiliates or assignees, including any Buyer Transferee) after the Closing Date, including, without limitation, any assignment of this Agreement, the Acquired Compounds License Agreement, or the Retained Compounds Royalty Agreement, any change in Tax residency, any change in the party paying or otherwise delivering any amounts pursuant to this Agreement, the Acquired Compounds License Agreement, or the Retained Compounds Royalty Agreement, or any failure to comply with applicable Law (each, a "**Withholding Tax Action**"), such amounts shall be increased as necessary so that, after all required deduction or withholding (including any deduction or withholding applicable to additional amounts payable under this Section 4.13), the party in respect of which such deduction or withholding was made receives an amount equal to the sum it would have received had no such Withholding Tax Action occurred. The Selling Entities acknowledge and agree that the Selling Entities shall not transfer their rights or obligations pursuant to this Agreement, the Acquired Compounds License Agreement, or the Retained Compounds Royalty Agreement to a Person or entity that is not a "United States person" within the meaning of Section 7701(a)(30) of the Code and shall not make any payments pursuant to such agreements outside of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.14<u>Landos Books and Records</u>. From and after the Closing Date, Agent, Stockholders and Buyer Transferee shall, and shall cause their respective Affiliates (including [\*\*\*]) to, promptly notify and deliver to Landos any Books and Records, data and other written information to the extent relating to any of the Excluded Assets that, to the best knowledge of Agent, Stockholders, Buyer Transferee or any such Affiliate, is in any of such Persons' possession or Control, including without limitation those (i) pertaining to communications with the FDA, current licensees of any of the Retained Compounds, clinical research organizations or other vendors involved in preclinical or clinical development or drug formulation or manufacturing of the Retained Compounds or the existing drug substance and drug product inventory specifically relating to the Retained Compounds, including without limitation, raw materials, active pharmaceutical ingredient, bulk product, work in process and finished goods, labeling and packaging owned or Controlled by Agent or any Stockholder, regardless of where located (including a copy of a list of key contact persons and their contact information); (ii) pertaining to material communications with potential business partners with respect to potential business alliances or similar business arrangements; or (iii) consisting of all databases and raw and processed data, studies, surveys, reports, specifications, methods, drawings and instructions, including those prepared by or for Landos and any Subsidiary, Agent or any Stockholder or any of their respective customers (in both hard copy and modifiable electronic copy form).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3 <u>Obligations of the Buyer Transferee</u>. If the Selling Entities assign their rights hereunder to a Buyer Transferee, the Joinder Agreement, by incorporating by reference the provisions hereof, will provide that the Buyer Transferee will agree to indemnify and hold harmless the Landos Indemnified Parties from and against any and all Losses actually suffered, sustained or incurred by the Landos Indemnified Parties to the extent as a result of or arising out of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4<u>Procedure</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Notice</u>. In the event that an Indemnified Party seeks any indemnification with respect to any Loss, the Indemnified Party shall give notice to the other Party (the "**Indemnifying Party**") as promptly as practicable, and in any event within three (3) Business Days after becoming aware of such claims and shall provide the Indemnifying Party with such information with respect thereto as the Indemnifying Party may reasonably request. Such notice shall: (i) state in good faith that the Indemnified Party has or may have a claim for Losses; (ii) state in good faith the amount of such Losses that have been incurred, paid, reserved or accrued; (iii) specify in reasonable detail the individual items of such Losses included in the amount so stated and the nature of the claim to which such Losses are related and the provision of the Agreement which gives rise to the claim; and (iv) with respect to Third Party Claims, include copies of material communications and documentation, any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, bill or other document evidencing or asserting the same. Notwithstanding the foregoing, the rights of any Indemnified Party to be indemnified in respect of any Loss resulting from the asserted liability shall not be adversely affected by the Indemnified Party's failure to timely give notice unless (and then only to the extent that) the Indemnifying Party is materially prejudiced thereby; provided, that an Indemnifying Party shall not have any liability for Losses unless notice with respect to any such claim is received by prior to the expiration of the survival period for such representation, warranty, covenant or agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Defense</u>. The Indemnifying Party shall have the right, upon written notice to the Indemnified Party within thirty (30) days of receipt of timely notice from the Indemnified Party in respect of a claim by any Person other than the Parties arising out of or involving a Loss by such Person against an Indemnified Party (other than a Tax Claim asserted against any Landos Indemnified Party) (a "**Third Party Claim**"), to assume the defense thereof at the expense of the Indemnifying Party with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party. Landos shall control the defense of any Tax Claim brought against any Landos Indemnified Party. If the Indemnifying Party does not expressly elect to assume the defense of such Third Party Claim within the time period and otherwise in accordance with the first sentence of this Section 5.4(b), the Indemnified Party shall have the sole right to assume the defense of such Third Party Claim. The party not controlling the defense of the Third Party Claim shall have the right to employ separate counsel and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such party unless, in the written opinion of outside counsel to the Indemnified Party, it is advisable for the Indemnified Party to be represented by separate counsel due to actual or potential conflicts of interest, in which case the Indemnified Party shall have the right to employ counsel to represent it and in that event the reasonable documented out-of-pocket fees and expenses of such separate counsel shall be paid by the Indemnifying Party. The party not controlling the Third Party Claim (the "**Non Controlling Party**") shall reasonably cooperate with the party controlling the Third Party Claim (the "**Controlling Party**") in such defense and make available to the Controlling Party all witnesses, pertinent records, materials and information in the Non Controlling Party's possession or under the Non Controlling Party's control relating thereto as is reasonably required by the Controlling Party; provided, however, that such actions and cooperation by the Non Controlling Party will not unduly disrupt the operations of the Non Controlling Party's business or cause the Non Controlling Party to waive any statutory or common law privileges, breach any confidentiality obligations owed to Third Parties or otherwise cause any confidential information of the Non Controlling Party to become public. The Controlling Party shall not, without the prior written consent of the Non Controlling Party (which consent shall not be unreasonably withheld, conditioned or delayed), enter into any settlement or compromise or consent to the entry of any judgment with respect to such Third Party Claim; provided, however, that, if an Indemnifying Party is proposing to enter into any settlement or compromise or consent to the entry of any monetary judgment with respect to such Third Party Claims, such consent of Indemnified Party shall not be required if (i) the Indemnifying Party agrees to pay or cause to be paid any amounts payable pursuant to such settlement, compromise or judgment and such settlement, compromise or judgment includes no admission of liability by or other obligation on the part of the Indemnified Party, and (ii) such settlement compromise or judgment includes an unconditional written release by the claimant or plaintiff of the Indemnified Party from all liability in respect of such Third Party Claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5<u>Survival of Representations and Warranties</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Each covenant and agreement to be performed subsequent to Closing contained in this Agreement or in any Transaction Documents delivered pursuant to this Agreement shall survive the Closing and be enforceable until ninety (90) days after the expiration of the statute of limitations following the date all performance thereunder was due to be performed. All representations and warranties and any covenant and agreement to be performed prior to Closing, in either case contained in this Agreement or in any other Transaction Documents delivered pursuant to this Agreement shall survive the Closing for a period of nine (9) months, and shall thereafter expire, except that any representation, warranty or covenant with respect to which a claim has been made for a breach thereon prior to such date shall survive until such claim is resolved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The limitations on survival set forth in this Section 5.5 shall not apply to the representations and warranties set forth in the following Sections of Schedule 3.1: 1 (Organization and Related Matters), 2(a) (Authorization) and 12 (No Brokers or Finders) (the "**Landos Fundamental Representations**"), all of which shall survive until ninety (90) days after expiration of the applicable statute of limitations, including waivers and extensions thereof.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The limitations on survival set forth in this Section 5.5 shall not apply to the representations and warranties set forth in the following Sections of Schedule 3.2 and Schedule 3.3: 1 (Organization and Related Matters), 2 (Authorization) and 4 (No Brokers or Finders) (the "**Stockholder and Buyer Transferee Fundamental Representations**"), all of which shall survive until ninety (90) days after expiration of the applicable statute of limitations, including waivers and extensions thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6<u>Limitations on Indemnification</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Notwithstanding anything to the contrary contained in this Agreement: (i) except in respect of the Landos Fundamental Representations and the Stockholder and Buyer Transferee Fundamental Representations, as applicable, no indemnification shall be available under Section 5.1(a), Section 5.2(a) or Section 5.3(a) for any individual claim or series of related claims based on a similar set of operative facts (1) unless such claim or series of related claims is for indemnifiable Losses greater than [\*\*\*] (the "**De Minimis Amount**") in which case the Indemnified Party shall be entitled to recover for all such indemnifiable Losses in connection with such claim or series of related claims (including the De Minimis Amount), and (2) unless and until the aggregate amount of indemnifiable Losses under Section 5.1(a), Section 5.2(a) or Section 5.3(a), as applicable, equals or exceeds [\*\*\*] (the "**General Deductible**"), in which case the Indemnified Party shall be entitled to recover for all such indemnifiable Losses in excess of the amount of (but not inclusive of) the General Deductible; and (ii) no indemnification shall be available under Section 5.1(a), Section 5.2(a) or Section 5.3(a) (1) in excess of [\*\*\*] other than in respect of the Landos Fundamental Representations and Stockholder and Buyer Transferee Fundamental Representations, as applicable, and (2) in respect of the Landos Fundamental Representations or the Stockholder and Buyer Transferee Fundamental Representations, as applicable, in excess of [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)If an Indemnifying Party has indemnified any Indemnified Party under this Article V for any Losses that are actually recovered by the Indemnified Party under any policies of insurance (net of documented associated expenses and costs of recovery to the extent arising out of, related to or resulting from the relevant Losses), then the Indemnified Party will promptly reimburse the Indemnifying Party in the event of recovery by such Indemnified Party under any such insurance policy subsequent to any indemnification payment hereunder with respect thereto. For purposes of calculating the amount of Loss incurred by an Indemnified Party for purposes of this Agreement there shall be deducted an amount equal to the amount of any other indemnification payments, contribution payments, reimbursements or refunds that are received by such Indemnified Party or any of such Indemnified Party's Affiliates in connection with such Losses or the circumstances giving rise thereto. Each Indemnified Party shall use commercially reasonable efforts to mitigate any Losses, which in the absence of mitigation might give rise to or increase Losses in respect of any claim under this Article V. In no event will multiple recovery for any Losses be allowed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7<u>Exclusive Remedy</u>. Each Party acknowledges and agrees that, from and after the Closing, this Article V will provide the exclusive remedy of the Indemnified Parties hereunder against Indemnifying Parties hereunder for any breach of any representation, warranty, covenant or other claim arising out of or relating to this Agreement, the certificates to be delivered hereunder or the Contemplated Transactions. No Indemnified Party may avoid the limitations on liability, recovery and recourse set forth in this Article V by seeking damages for breach of contract, tort or pursuant to any other theory or liability. Nothing in this Section 5.7 shall limit any Person's right to seek and obtain any equitable relief to which any Person shall be entitled to pursuant to Section 6.16.

If, after Closing, Agent identifies any property, right or asset (other than any property, right or asset included with the Excluded Assets) that has not, and should have been, transferred to the Selling Entities pursuant to this Agreement, Landos shall transfer (or procure the transfer of) such property, right or asset (and any related liability which is an Assumed Liability) to the Selling Entities as soon as practicable and at no cost to Agent, Stockholders or Buyer Transferee. If following Closing, any property, right or asset (other than any property, right or asset expressly included in the Acquired Assets) is found to have, and should not have been, transferred to the Selling Entities pertaining to Excluded Assets or Excluded Liabilities pursuant to this Agreement, the Selling Entities shall transfer (or procure the transfer of) such property, right or asset to Landos as soon as practicable and at no cost to the Agent, Selling Entities or Buyer Transferee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)After the Closing, the Parties shall, and shall cause their respective Affiliates to, cooperate fully, as and to the extent reasonably requested by each other, in connection with the preparation and filing of all Tax Returns and the defense of any Tax investigation, action, audit, or other proceeding by a Governmental Entity (each, a "**Tax Claim**"), in each case, with respect to the Acquired Business, the Acquired Assets, and the Licensed Technology. Such cooperation shall include providing any records and other information reasonably requested by a Party and reasonably relevant to such Tax Returns or Tax Claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.6<u>Dispute Resolution</u>.

If mediation is unsuccessful, any action or proceeding arising out of or relating to this Agreement, or between the Parties, shall be brought exclusively in Wilmington, Delaware, in either the State of Delaware, County of New Castle, or the United States District Court for the District of Delaware (the "**Exclusive Courts**"). Each of the Parties to this Agreement irrevocably submits himself or itself to the jurisdiction and venue of the Exclusive Courts, and such Exclusive Courts shall have exclusive jurisdiction over, and shall be considered proper venue for, any and all claims arising out of or relating to this Agreement or between the Parties. This provision, as well execution of this Agreement, does not mean that any of the Parties avail themselves of jurisdiction in Delaware for any other reason other than the enforcement of this Agreement, and shall not provide a basis for the exercise of personal jurisdiction over any of the Parties with respect to any other claim. In the event any Party seeks to enforce the terms of this Agreement or any Exhibit, the non-prevailing Parties shall be responsible for the prevailing Party's reasonable attorneys' fees in any such judicial proceeding, along with costs and disbursements of such judicial proceeding.

**Landos Biopharma Announces Transfer of LANCL Portfolio, including Omilancor, LABP-104 and LABP-111 to Landos' Founder** 

Transaction Solidifies Company's Near-Term Strategic Focus on Advancing Clinical Development of NX-13

Company Remains On-Track to Initiate the NX-13 Phase 2 Proof-of-Concept Trial in Ulcerative Colitis in the Second Quarter of 2023

**NEW YORK, February 28, 2023 –** Landos Biopharma, Inc. (NASDAQ: LABP) ("Landos" or the "Company"), a clinical-stage biopharmaceutical company developing novel, oral medicines for patients with autoimmune diseases, today announced the transfer of its LANCL portfolio, including Omilancor, LABP-104 and LABP-111 to Dr. Josep Bassaganya-Riera, Ph.D., the founder of Landos who previously served as its Chairman, President and CEO, and certain affiliated individuals and entities.

Under the terms of the transaction, the Company will repurchase approximately 9.1 million Landos shares previously held by Dr. Bassaganya-Riera and certain affiliated individuals and entities, representing approximately 23% of Landos' outstanding shares, for $3.0 million in cash and assign exclusive global rights to develop, manufacture and commercialize the LANCL portfolio, including Omilancor, LABP-104, and LABP-111 to Dr. Bassaganya-Riera and certain affiliated individuals and entities. Additionally, the parties have entered into a royalty agreement whereby Landos will receive a 6% royalty on future commercial sales from any approved products developed from the LANCL portfolio and Dr. Bassaganya-Riera and certain affiliated individuals and entities will receive a 2% royalty on future sales from NX-13, LABP-73, LABP-66, and LABP-69, if approved. The parties have also agreed to a mutual, general release of liabilities and claims.

The transaction follows a comprehensive strategic review of the Landos portfolio. Based on this review, the Landos leadership team and Board of Directors believe that the transaction with Dr. Bassaganya-Riera maximizes long-term value for Landos shareholders, including:

-Enhanced focus on advancing the clinical development of NX-13, a novel, oral, gut-selective NLRX1 agonist as a once-daily treatment for Ulcerative Colitis ("UC"), through a Phase 2 proof-of-concept trial;

-Continued participation in future upside of the LANCL portfolio through the 6% royalty on future sales of Omilancor, LABP-104 and LABP-111, if approved;

-Improved capital structure through the acquisition and retirement of approximately 9.1 million Landos shares previously held by Dr. Bassaganya-Riera and certain affiliated individuals and entities, representing approximately 23% of Landos' outstanding shares; and

-Mutual, general release of liabilities and claims.

------

"This transaction is consistent with the strategic plan we announced last month to focus our resources on advancing the clinical development of NX-13," said Gregory Oakes, President and Chief Executive Officer of Landos. "We have engaged with potential partners over the past year and based on the interest received, as well as Dr. Bassaganya-Riera's previous role in developing these assets, we believe this transaction is the best path forward to maximize the value of the LANCL portfolio. This provides a potential developmental path for programs that we were not prioritizing at this time, while delivering compelling value to our shareholders, including potential future upside tied to the commercialization of these programs."

"This transaction further sharpens our focus on advancing NX-13 and we look forward to sharing additional details about our Phase 2 proof-of-concept clinical trial in moderate-to-severe UC patients, which will be dose-ranging, blinded, placebo-controlled, and statistically powered. As we noted in January, our goal is to generate as much meaningful data as possible, as quickly as possible, to build on our already impressive data foundation. We are on track for first site activation and patient enrollment next quarter and look forward to reporting topline data by the fourth quarter of 2024," continued Mr. Oakes.

Landos will continue with the exclusive collaboration and license agreement with LianBio for the development and commercialization of NX-13 in Greater China, including mainland China, Hong Kong, Taiwan, and Macau, as well as other select Asian markets.

Cooley LLP served as legal advisor to Landos in connection with the transaction. Eilenberg & Krause LLP served as legal advisor to Dr. Bassaganya-Riera.

**Enhanced Focus on NX-13 with Significant Optionality for Broader Pipeline**

Consistent with Landos' strategic update in January 2023, this transaction streamlines the Company's portfolio, enhancing its focus and resources on advancing NX-13.

Landos previously announced top-line results from its NX-13 Phase 1b trial in UC patients in August 2022. The data showed favorable safety and tolerability profiles across a range of doses, as well as signals of clinical improvement as soon as two weeks in patients' symptoms and four weeks by endoscopy in exploratory endpoints. NX-13, with its unique mechanism of action, favorable safety profile, once-daily dosing, and promising early clinical data, could potentially transform the current UC treatment paradigm.

Following this transaction, the Company will have three novel, pre-clinical programs in its portfolio, including: **LABP-69**, a novel PLXCD2 agonist in development for the treatment of Rheumatoid Arthritis and Diabetic Nephropathy; **LABP-66,** a novel NLRX1 agonist in development for the treatment of Multiple Sclerosis, Alzheimer's Disease, and other debilitating central nervous system diseases; and **LABP-73**, a novel NLRX1 agonist in development for the treatment of Asthma and Chronic Obstructive Pulmonary Disease.

**About Landos Biopharma**

Landos Biopharma is a clinical stage biopharmaceutical company focused on the development of first-in-class therapeutics for patients with autoimmune disease. The Company's mission is to create safer and more effective treatments that address the therapeutic gap in the current treatment paradigm.

------

Landos has a portfolio of novel targets anchoring two libraries of immunometabolic modulation pathways, including four potentially first-in-class, once-daily therapies targeting eight indications in the immunology space.

The Company is currently focused on advancing the clinical development of NX-13 in UC, and is on-track to initiate a Phase 2 proof-of-concept trial in the second quarter of 2023.
