Immedica shall pay an amount in cash equal to the applicable milestone payment listed next to such Milestone Event in the table below (each such payment, a “Milestone Payment”), less any Milestone Set-Offs, in accordance with Section 1.2(b). The Milestone Events and corresponding Milestone Payments are as follows:

(d) Notwithstanding anything to the contrary in this Agreement, (i) the maximum aggregate amount of Milestone Payments Immedica shall be obligated to pay to Aeglea pursuant to the table set forth in this Section 1.2 shall be $100,000,000, (ii) each unique row in the table set forth in this Section 1.2 represents a separate Milestone Event, and accordingly, there are five (5) distinct Milestone Events, (iii) each Milestone Event may be achieved no more than one time, (iv) each Milestone Payment shall be payable only once, if at all, upon the first achievement of the applicable Milestone Event (regardless of (A) any subsequent or repeated achievement of a Milestone Event and (B) the number of subsequent Products achieving such Milestone Events).

(e) Notwithstanding anything in this Agreement to the contrary, the Parties acknowledge and agree that, in addition to any other right or remedy under this Agreement, Immedica shall have the right, but not the obligation, from time to time to set off against (x) any Milestone Payment that is owed and has not yet been paid and (y) if applicable, the Specified Patents Holdback Amount if any portion of such amount continues to be held back in accordance with Section 1.2(f) (clauses (x) and (y), the “Available Remedy Amounts”) (each of the following clauses (i), (ii) and (iii), a “Milestone Set-Off”): (i) any Losses for which any Immedica Indemnified Party is entitled to indemnification pursuant to, and in accordance with, Article VII, (ii) any Losses in respect of claims for intentional fraud or willful misconduct, and (iii) any Necessary IP Payments already paid or accrued or then payable by any Immedica Indemnified Party; provided that Immedica shall not be entitled to set off any Necessary IP Payment to the extent that any Immedica Indemnified Party receives an indemnification payment for such Necessary IP Payment pursuant to Article VII.

Any Milestone Set-Off taken by Immedica will be accompanied by a written notice including an accounting of such Milestone Set-Off (“Set-Off Notice”); provided that any failure by Immedica to provide any such Set-Off Notice to Aeglea shall not impact Immedica’s rights under this Section 1.2(e). Upon reasonable written request by Aeglea, Immedica will provide reasonable documentation in support of any Milestone Set-Off, such request to be made no more than six (6) months after the date of the applicable Set-Off Notice. The Parties shall negotiate in good faith to seek to resolve any dispute regarding any Set-Off Notice before making any claim to resolve such dispute.

(f) Aeglea and Immedica agree to be bound by and comply with the terms and conditions set forth on Schedule 1.2(f) as though set forth in full herein.

(g) For purposes of this Section 1.2:

(i) The definitions of Reimbursement Earnout Amount, Actual Reimbursement Percentage, Actual Reimbursement Price, Expected Reimbursement Price and Pricing Reimbursement Approval are stated with respect to a 2 mg vial of the Product. In the event that any of the Milestone Events set forth in the first three rows of the table set forth in this Section 1.2 occurs with respect to a vial with a different amount of Product, the amounts in Euros and British Pounds Sterling will be proportionally adjusted, on a linear basis based on mg of Product, for purposes of calculating the Reimbursement Earnout Amount. By way of example, in the event that any of the Milestone Events set forth in the first three rows of the table set forth in this Section 1.2 occurs with respect to a 4 mg vial of Product, then the Expected Reimbursement Price of such 4 mg vial of Product (A) with respect to France would be [*]/4 mg vial of such Product; (B) with respect to Germany would be [*]/4 mg vial of such Product; and (C) with respect to the United Kingdom would be [*]/4 mg vial of such Product, and the Reimbursement Earnout Amount for such 4 mg vial of such Product would be determined using such amounts.

By way of examples, if the Actual Reimbursement Price for a 2 mg vial of the Product received by Immedica in France is [*], then the Actual Reimbursement Percentage for such 2 mg vial of the Product in France is [*] or 93%; and if the Actual Reimbursement Price for a 2 mg vial of the Product received by Immedica in Germany is [*], then the Actual Reimbursement Percentage for such 2 mg vial of the Product is [*] or 87%.

(iii) “Actual Reimbursement Price” means, with respect to a given country, the price reimbursed by the applicable Governmental Authority, net of any mandatory rebates, for a 2 mg vial of the Product in such country pursuant to the Pricing and Reimbursement Approval for such 2 mg vial of the Product in such country, where such reimbursed price may be the listed price or a discounted price, net of any mandatory rebates, of such 2 mg vial of the Product that is agreed and approved between Immedica and such applicable Governmental Authority.

(iv) “Expected Reimbursement Price” means, (A) with respect to France, [*]/2 mg vial of the Product; (B) with respect to Germany, [*]/2 mg vial of the Product; and (C) with respect to the United Kingdom, [*]/2 mg vial of the Product.

(vii) [Reserved].

(x) “Reimbursement Earnout Amount” means, with respect to a 2 mg vial of the Product in a given country: (A) if the Actual Reimbursement Percentage of such 2 mg vial of the Product in such country is equal to 100% or more, $10,000,000, (B) if the Actual Reimbursement Percentage of such 2 mg vial of the Product in such country is less than 80%, zero, and (C) if the Actual Reimbursement Percentage

4

of such 2 mg vial of the Product in such country is 80% or more but less than 100%, an amount equal to the sum of (i) $3,333,333 and (ii) the product of (A)(x) the Actual Reimbursement Percentage for such 2 mg vial of the Product in such country minus 80% divided by (y) 20% multiplied by (B) $6,666,666; or, in the case of the foregoing clause (C), the formula expressed as follows:

Section 2.5 Undisclosed Contracts. If any Program Contract was not set forth on Schedule 2.1(b)(i) or 2.2(b)(viii) and is identified following the Closing, Aeglea shall promptly notify Immedica in writing giving sufficient disclosure of such Program Contract and provide Immedica with a copy thereof, in which case Immedica shall thereafter be entitled to deem such Program Contract an “Assigned Contract” and the provisions of this Agreement (including Section 2.6) shall apply to such Program Contract as though it were an Assigned Contract, and Aeglea and Immedica shall take such action reasonably requested by Immedica (and consistent with the other provisions of this Agreement (including Section 2.6)) to assign such Program Contract to Immedica. Neither Aeglea nor any of its Subsidiaries shall voluntarily terminate any such nondisclosed Program Contract prior to providing Immedica with written notice of the intent to terminate and giving Immedica a reasonable period of time to review such Program Contract and determine whether to exercise its right to treat such Program Contract as an “Assigned Contract.”

Section 2.6 Non-Assignable Assets. Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement or the consummation of the Transaction shall be construed as an attempt or agreement to assign any Acquired Asset, including any Contract, Permit, certificate, approval, authorization or other right, which by its terms or by Law is non-assignable without the consent of a Third Party or a Governmental Authority or is terminable or cancelable by a Third Party or a Governmental Authority in the event of an assignment (any such Acquired Asset, a “Non-assignable Asset”) unless and until such consent shall have been obtained. Aeglea shall and shall cause its Subsidiaries to use all commercially reasonable efforts to obtain any such consents with respect to the Acquired Assets, including all Non-assignable Assets, and including all consents set forth on Schedule 4.4(a), as promptly as

9

practicable, and shall cooperate as reasonably requested by Immedica in any efforts made by Immedica or any of its Affiliates to obtain such consent. If any such consent or approval is not obtained, Aeglea shall, and shall cause its Subsidiaries to, provide to Immedica the benefits of such Non-assignable Asset in accordance with this Agreement and shall enforce, or cause its Subsidiaries to enforce, at the request of and for the benefit of Immedica, any rights of Aeglea or its Subsidiaries arising thereunder, including the right to seek any available remedies or to terminate in accordance with the terms thereof, in each case at Immedica’s cost and expense. Aeglea shall and shall cause its Subsidiaries to promptly pay to Immedica when received all monies received by Aeglea or any of its Affiliates under any such Non-assignable Asset or any claim, right or benefit arising thereunder, except to the extent the same represents an Excluded Asset. As a condition to Aeglea providing Immedica with the benefits of any Non-assignable Asset, Immedica shall perform, in the name or on behalf of Aeglea or its applicable Subsidiary, all obligations of Aeglea or its applicable Subsidiary and shall indemnify Aeglea or its applicable Subsidiary for any Liabilities first arising thereunder following the Closing, except to the extent such Liabilities relate to the gross negligence or willful misconduct of Aeglea or any Aeglea Indemnified Party or the failure of Aeglea or any Aeglea Indemnified Party to follow the reasonable written (email being sufficient) instructions of Immedica or any of its Subsidiaries with respect to such Non-assignable Asset. To the extent that, in connection with obtaining a Third Party’s consent under any Non-assignable Asset, one or more of the Parties enter into an agreement with such Third Party that provides for an allocation of liability among the Parties with respect to such Non-assignable Asset that is inconsistent with the terms of this Agreement, the Parties agree that, as among themselves, the provisions of this Agreement shall control.

Section 2.7 Designated Buyer. Notwithstanding anything to the contrary contained in this Agreement, Immedica may elect to have any or all of the Acquired Assets sold, assigned, conveyed, transferred or delivered to, or any of the Assumed Liabilities assumed by, one or more of its Subsidiaries, in each case as set forth in the Instruments to be delivered at Closing; provided, however, that no such sale, assignment, conveyance, transfer or delivery shall (a) relieve Immedica of any of its obligations to Aeglea hereunder with respect to the Assumed Liabilities or (b) otherwise increase or expand the obligations of Aeglea hereunder.

Section 2.8 ADA Assay License. Aeglea and its Subsidiaries hereby grant to Immedica and its Affiliates a royalty-free, fully paid-up, worldwide, fully transferable, irrevocable, perpetual, non-exclusive, sublicensable (including the right to sublicense through multiple tiers) license under their respective rights in and to the ADA Assays to use and otherwise Exploit the ADA Assays for any and all purposes.

Immedica is duly qualified to do business as a foreign entity and, to the extent legally applicable, in good standing as a foreign entity in each jurisdiction where such qualification is necessary, except for those jurisdictions where the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to materially impede or materially delay the consummation by Immedica of the Transactions or the performance of its obligations under this Agreement or any Instrument to which it is a party.

Each of the Instruments to which Immedica is a party has been, or will be at or prior to the Closing, duly and validly executed and delivered by Immedica and (assuming the due authorization, execution and delivery by the other parties thereto) each of such Instruments, when so executed and delivered, will constitute the legal, valid and binding obligations of Immedica, enforceable against it in accordance with its terms, subject to the effect of any applicable Laws relating to bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or preferential transfers, or similar Laws relating to or affecting creditors’ rights generally and subject, as to enforceability, to the effect of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at Law).

(d)With respect to the Product, from and after the Closing Date, until the later of (x) the date on which Immedica (or its applicable Affiliate) receives an assignment or transfer of the Transferred Product Registration for the Product or a replacement thereof naming Immedica (or its applicable Affiliate) as the Product Registration holder for the Product, and (y) such other date on which regulatory responsibilities are assumed by Immedica in accordance with applicable Law, Aeglea shall, with respect to the Product, operate in compliance with the terms of the relevant Transferred Product Registration, and with all applicable Law and all requirements of relevant Governmental Authorities.

INDEMNIFICATION

Section 7.1 Survival. The representations and warranties of the Parties contained in this Agreement or in any certificate or other writing delivered pursuant hereto shall survive until 5:00 p.m. Eastern Time on the twelve (12)-month anniversary of the Closing Date; provided, that (a) the representations and warranties of Aeglea contained in Sections 4.1, 4.2, 4.3, 4.4(a)(i), 4.8(b) and 4.15 and the first two sentences of Section 4.5(a) (collectively, the “Fundamental Representations”) shall survive the Closing until 5:00 p.m. Eastern Time on May 22, 2026 and (b) the representations and warranties of Aeglea contained in Section 4.11 (the “IP Representations”) and the representations and warranties of Aeglea contained in Section 4.8(a) shall survive the Closing until 5:00 p.m. Eastern Time on May 22, 2026 (as applicable, the “Survival Period”). The covenants and agreements of the Parties contained in this Agreement or in any certificate or other writing delivered pursuant hereto shall survive indefinitely or for such shorter period explicitly specified therein. Upon termination and expiration of any representation and warranty, covenant or agreement for the purposes of indemnification, all indemnification obligations with respect to such representation and warranty, covenant or agreement shall likewise terminate and expire, except to the extent that the Person to be indemnified pursuant to this Article VII (the “Indemnified Party”) shall have (in good faith) given written notice a claim to the indemnifying party pursuant to this Article VII (the “Indemnifying Party”) before termination of the applicable Survival Period, in which event the representation and warranty, covenant or agreement alleged in the claim to have been breached and any associated right to indemnification shall continue until such claim for indemnification is resolved. For the avoidance of doubt, it is the intention of the Parties that the foregoing respective Survival Periods and termination dates supersede any applicable statutes of limitations that would otherwise apply to such matters.

Section 7.2 Indemnification by Aeglea. From and after the Closing Date and subject to the provisions of this Article VII, Aeglea shall reimburse, defend, indemnify and hold Immedica and its directors, officers, employees, Affiliates, agents, attorneys and Representatives, and each of their respective successors and permitted assigns (collectively, the “Immedica Indemnified Parties”) harmless from and against any and all Losses incurred, resulting or arising from or relating to:

25

(a)the failure of any representation or warranty of Aeglea contained in this Agreement to be true and correct as of the Closing Date (except for any such representation and warranty that addresses matters only as of a specific date, which representation and warranty shall be true and correct as of such specific date); provided that for purposes of (i) determining whether any failure of a representation or warranty to be true and correct has occurred and (ii) calculating the amount of any Losses relating thereto, in each case, the representations and warranties shall be considered and applied without regard to any reference to materiality, Material Adverse Effect or similar materiality qualification set forth therein; and provided, further, that if the absence of an asset has resulted in a failure of a representation or warranty set forth in Section 4.8(a) to be so true and correct, to the extent that such failure may be cured (in whole or in part) by the delivery of such asset to Immedica after the Closing (including by the grant of a license if such absent asset was a license), Aeglea’s indemnification obligations hereunder may (but without limiting any obligation set forth in this Agreement) be cured to such extent (and only such extent) by delivery of such asset, and the remaining indemnification obligations with respect to such failure (if any) shall be satisfied in accordance with the other provisions of this Article VII;

(b)any breach of or failure to perform any covenant or obligation made or to be performed by Aeglea in this Agreement or in any certificate or other writing delivered pursuant hereto;

(c)any Excluded Asset or Excluded Liability (including, for the avoidance of doubt, in respect of any Person seeking to impose any Excluded Liability on any of the Immedica Indemnified Parties based upon any theory of successor liability or based upon any claim of fraudulent transfer or any other claim alleging that the consideration paid in connection with the consummation of the transactions contemplated hereby is insufficient for any reason); and

(d)the matters set forth on Schedule 7.2(d).

Section 7.3 Indemnification by Immedica. From and after the Closing Date and subject to the provisions of this Article VII, Immedica shall reimburse, defend, indemnify and hold each of Aeglea and its respective directors, officers, employees, Affiliates, agents, attorneys, Representatives, successors and permitted assigns (the “Aeglea Indemnified Parties”) harmless from and against any and all Losses incurred, resulting or arising from or relating to:

(a) the failure of any representation or warranty of Immedica contained in this Agreement to be true and correct as of the Closing Date (except for any such representation and warranty that addresses matters only as of a specific date, which representation and warranty shall be true and correct as of such specific date);

(b) any breach of or failure to perform any covenant or obligation made by Immedica in this Agreement; and

26

(c)the Assumed Liabilities, except (notwithstanding anything to the contrary herein) to the extent due to the breach by Aeglea of this Agreement.

Section 7.4 Indemnification Procedures.

(a)A claim for indemnification for any matter not involving a Third-Party Claim may be asserted by prompt written notice to the Indemnifying Party, including, to the extent known, the amount of the claim or an estimate thereof, to such Indemnifying Party; provided that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any indemnification obligation hereunder unless (and then solely to the extent that) the Indemnifying Party is materially prejudiced as a result of such failure.

(b)In the event that any Legal Proceedings shall be instituted, or that any claim or demand shall be asserted or threatened in writing, by any Person not party to this Agreement in respect of which an Indemnification Claim may be made under this Agreement (a “Third-Party Claim”), the Indemnified Party shall promptly cause written notice of the assertion or written threat of any Third-Party Claim of which it has knowledge that is or may be covered by this indemnity to be delivered to the Indemnifying Party; provided that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any indemnification obligation hereunder unless (and then solely to the extent that) the Indemnifying Party is materially prejudiced as a result of such failure. The Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the Indemnified Party, and to defend against, negotiate, settle or otherwise address any Third-Party Claim; provided, however, that prior to assuming control of such defense, the Indemnifying Party must acknowledge that it would have an indemnity obligation for the Losses resulting from such Third-Party Claim as provided under this Article VII if the material facts alleged in such Third-Party Claim at the time of its assumption of the defense are ultimately determined to be accurate; and provided, further, that the Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third-Party Claim and shall pay the fees and expenses of counsel retained by the Indemnified Party if (1) the Indemnifying Party does not deliver the acknowledgment referred to in the preceding proviso within 30 days of receipt of notice of the Third-Party Claim pursuant to this Section 7.4, (2) the Third-Party Claim is made by a Governmental Authority or relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (3) the Third-Party Claim seeks an injunction or equitable relief against the Indemnified Party or any of its Affiliates, (4) the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Third-Party Claim (after reasonable notice and opportunity to cure) or (5) the Third-Party Claim relates to Taxes. If the Indemnifying Party is entitled to and elects to defend against, negotiate, settle or otherwise address any Third-Party Claim, it shall within twenty (20) Business Days (or sooner, to the extent that the nature of the Third-Party Claim so requires) (“Dispute Period”) notify the Indemnified Party of its intent to do so. If the Indemnifying Party shall assume the defense of any Third-Party Claim, then the Indemnified Party may participate, at his or its own expense, in the defense of such Third-Party Claim; provided, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if (i) requested by the Indemnifying Party to participate, (ii) the named parties to any such Third-Party Claim (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party or (iii) representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to a conflict of interest between the Indemnified Party and the Indemnifying Party; provided, further, that the Indemnifying Party shall not be required to pay for more than one such counsel for all Indemnified Parties in connection with any Third-Party Claim. If the Indemnifying Party does not elect (if so entitled) within the Dispute Period to defend against, negotiate, settle or otherwise address any Third-Party Claim or fails

27

to notify the Indemnified Party of its election during the Dispute Period, the Indemnified Party shall have the right, but not the obligation, to defend against such Third-Party Claim; provided that the Indemnifying Party may nonetheless participate in the defense of such Third-Party Claim (but not control or make decisions related thereto) with its own counsel and at its own expense.

(c)If the Indemnifying Party elects to defend against, negotiate, settle or otherwise address any Third-Party Claim, the Indemnifying Party shall (i) conduct the defense of such Third-Party Claim with reasonable diligence and keep the Indemnified Party reasonably informed of material developments in the Third-Party Claim at all stages thereof; (ii) promptly submit to the Indemnified Party copies of all pleadings, responsive pleadings, motions and other similar legal documents and papers received or filed in connection therewith; (iii) permit the Indemnified Party and its counsel to confer on the conduct of the defense thereof; and (iv) permit the Indemnified Party and its counsel an opportunity to review all legal papers to be submitted prior to their submission (to the extent practical).

(d)The Parties agree to provide reasonable access to each other Party to such documents and information as may reasonably be requested in connection with the defense, negotiation or settlement of any such Third-Party Claim. The Indemnified Party shall have the right to negotiate, compromise and settle any Third-Party Claim for which the Indemnifying Party may have any Liability under this Agreement but only with the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may not enter into any compromise or settlement of, or cease to defend against, a Third-Party Claim unless the Indemnifying Party (i) has assumed the defense of such claim pursuant to this Section 7.4 and (ii)has received the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, the Indemnifying Party may enter into any compromise or settlement of any Third-Party Claim if (x) pursuant to or as a result of such compromise or settlement, (A) injunctive or other equitable relief would not be imposed against the Indemnified Party, (B) each claimant or plaintiff in such Third-Party Claim has given to the Indemnified Party an unconditional release from all Liability with respect to such Third-Party Claim, (C) a finding or admission of a violation of Law would not be made against the Indemnified Party, and (D) the Indemnified Party would not have a monetary Liability that will not be paid or reimbursed by the Indemnifying Party in full; (y) such Third-Party Claim would not reasonably be expected to have a material impact on the ongoing business of the Indemnified Party; and (z) such Third-Party Claim is not brought by a Governmental Authority.

(e)After any final non-appealable decision, judgment or award shall have been rendered by a Governmental Authority of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement or arbitration shall have been consummated, or the Indemnified Party and the Indemnifying Party shall have arrived at a mutually binding agreement with respect to an Indemnification Claim hereunder, the Indemnified Party shall forward to the Indemnifying Party notice of any sums due and owing by the Indemnifying Party pursuant to this Agreement with respect to such matter and the Indemnifying Party shall make prompt payment thereof by wire transfer in immediately available funds within thirty (30) days after the date of such notice or, if applicable, pursuant to the terms of the agreement reached with respect to the Indemnification Claim.

28

Section 7.5 Limitations on Indemnified Costs.

(a)Notwithstanding anything to the contrary in this Agreement, with the exception of intentional fraud and willful misconduct, no Indemnifying Party shall have any Liability for any Loss under Section 7.2(a) (other than in respect of the Fundamental Representations or the IP Representations) or Section 7.3(a) (other than in respect of the representations and warranties contained in Section 5.1, Section 5.2 and Section 5.3(i)), as applicable, (i) unless and until such Loss (or series of related Losses) equals or exceeds $15,000 (the “De Minimis Amount”), it being understood that if such Loss (or series of related Losses) does not exceed the De Minimis Amount, such Loss (or series of related Losses) shall not be applied to or considered for purposes of calculating the aggregate amount of Losses incurred by any Indemnified Parties pursuant to the immediately following clause (ii); and (ii) unless the aggregate amount of all Losses incurred by the Immedica Indemnified Parties under Section 7.2(a) (other than in respect of the Fundamental Representations or the IP Representations) or the Aeglea Indemnified Parties under Section 7.3(a) (other than in respect of the representations and warranties contained in Section 5.1, Section 5.2 and Section 5.3(i)), as applicable, exceeds $300,000 (the “Basket”), it being understood that if such Losses exceed the Basket, the applicable Indemnifying Party shall be obligated for only the Losses of the applicable Indemnified Parties in excess of the Basket.

(b)Notwithstanding anything to the contrary in this Agreement, with the exception of intentional fraud and willful misconduct, (i) Aeglea’s maximum aggregate Liability to the Immedica Indemnified Parties for any Loss under Section 7.2 (except for Sections 7.2(b) and 7.2(d), and except for Section 7.2(a) with respect to Fundamental Representations, IP Representations and the representations and warranties contained in Section 4.8(a)) shall not exceed $1,800,000 plus 15% of the aggregate Milestone Payments received or that become payable to Aeglea (calculated prior to giving effect to any Milestone Set-Off); (ii) Aeglea’s maximum aggregate Liability to the Immedica Indemnified Parties for any Loss under Section 7.2(a) with respect to the representations and warranties contained in Section 4.8(a) shall not exceed $2,400,000 plus 20% of the aggregate Milestone Payments that become payable to Aeglea (calculated prior to giving effect to any Milestone Set-Off); (iii) Aeglea’s maximum aggregate Liability to the Immedica Indemnified Parties for any Loss under Section 7.2(a) with respect to IP Representations shall not exceed $3,600,000 plus 30% of the aggregate Milestone Payments that become payable to Aeglea (calculated prior to giving effect to any Milestone Set-Off); (iv) Aeglea’s maximum aggregate Liability to the Immedica Indemnified Parties for all Losses under Section 7.2(a) with respect to Fundamental Representations, Section 7.2(b) and Section 7.2(d) shall not exceed the Initial Payment plus 100% of the aggregate Milestone Payments that become payable to Aeglea (calculated prior to giving effect to any Milestone Set-Off.

(c)Aeglea agrees that if a Third-Party Claim is made against an Immedica Indemnified Party concerning an Excluded Asset or Excluded Liability, Aeglea shall, at its sole cost and expense, (i) communicate to the Person making such Third-Party Claim that Aeglea (rather than such Immedica Indemnified Party) is responsible for or otherwise liable in respect of such Excluded Asset or Excluded Liability (and otherwise acknowledge that Aeglea rather than such Immedica Indemnified Party is the appropriate party in interest) and (ii) use commercially reasonable efforts to cause such Immedica Indemnified Party to be released or otherwise dismissed from such Third-Party Claim and any related Legal Proceeding.

(d)With respect to any Milestone Set-Off pursuant to Section 1.2(e) (and subject to the limitations set forth in Sections 7.5(a) and 7.5(b) and the terms of Section 1.2(e)), if at the time any Milestone Payment is due and payable (or any portion of the Specified Patents Holdback Amount continues to be held back in accordance with Section 1.2(f)), there shall be any outstanding Indemnification Claim delivered in accordance with Section 7.4, the amount of Losses with respect to which shall not have been finally determined in accordance with this Article VII, then Immedica shall be entitled, but shall not be required, to withhold from such Available Remedy Amount, the amount of Losses the applicable Immedica

29

Indemnified Party reasonably estimates to be subject to such Indemnification Claim. If the final amount of Losses for such Indemnification Claim is determined in accordance with this Article VII to be less than the amount withheld from such Available Remedy Amount, then Immedica shall promptly, and in any event within five (5) Business Days following the final determination of the amount of such Losses, deliver the difference to Aeglea by wire transfer of immediately available funds to an account designated in writing by Aeglea (provided that no amount set off against the Specified Patents Holdback Amount shall be required to be so delivered to Aeglea unless, prior to such time, the Specified Patents Holdback Amount was required to be released to Aeglea in accordance with the last sentence of Section 1.2(f)). If the final amount of Losses for such Indemnification Claim is determined in accordance with this Article VII to exceed the amount by which such Available Remedy Amount was reduced for such claim, then Immedica shall continue to be entitled to indemnification for the amount of such excess subject to the terms and conditions of this Article VII.

(e)In no event shall any Indemnifying Party have Liability to any Indemnified Party for any consequential, special, incidental, indirect, punitive or exemplary damages, except, in each case of the foregoing damages, to the extent (i) any of the foregoing are payable to a Third Party pursuant to a Third-Party Claim, (ii) in the case of consequential or indirect damages, to the extent such damages are the reasonably foreseeable result of the event that gave rise thereto or the matter for which indemnification is sought hereunder, (iii) arising under Section 7.2(d) or (iv) any of the foregoing arise as a result of intentional fraud or willful misconduct by the Indemnifying Party. No Indemnified Party shall be entitled to recover from an Indemnifying Party more than once in respect of Losses resulting from a single or series of related claims. Any Liability for indemnification hereunder shall be determined without duplication of recovery by reason of state of facts giving rise to such Liability constituting a breach of more than one representation, warranty, covenant or agreement.

(f)The amount of any and all Losses under this Article VII shall be determined net of (i) any Tax benefit actually realized by the applicable Indemnified Parties in the form of Tax refunds received or a reduction of Taxes otherwise owed in the taxable year of such Losses, and (ii) any insurance proceeds actually received by the applicable Indemnified Parties in connection with the facts giving rise to the right of indemnification (net of any costs of recovery, deductibles or increased premiums as a result of paying such insurance claims), it being agreed that if third-party insurance or indemnification proceeds in respect of such facts are recovered by the Indemnified Party subsequent to the Indemnifying Party’s making of an indemnification payment in satisfaction of its applicable indemnification obligation, such proceeds shall be promptly remitted to the Indemnifying Party to the extent of the indemnification payment made. The Parties shall make commercially reasonable efforts to mitigate any Losses subject to an Indemnification Claim in accordance with applicable Law; provided, that (A) no Party is required to bring any suit, action or proceeding in connection with such mitigation and (B) any Liability of any Indemnifying Party under this Agreement for Losses suffered or incurred by the Indemnified Party shall include the reasonable costs and expenses suffered or incurred by the Indemnified Party in performing its mitigation obligations hereunder.

Section 7.6 Sources of Recovery. The Milestone Set-off shall be the sole and exclusive recourse for any and all payments that may become owing to the Immedica Indemnified Parties pursuant to a claim for indemnification under this Article VII (other than (A) pursuant to Section 7.2(d), (B) pursuant to Section 7.2(b) with respect to any breach of or failure to perform any covenant or obligation contained in this Agreement that by its terms contemplates performance thereof following the Closing and such breach remains uncured for a period greater than sixty (60) days after Immedica provides written notice of such breach, and (C) with respect to willful misconduct or intentional fraud (collectively, the “Excluded Indemnity Matters”)); provided that (i) the Immedica Indemnified Parties shall not be entitled to recover

30

any Loss (or series of related Losses) against Aeglea or any of its Subsidiaries (other than by means of a Milestone-Setoff) with respect to an Excluded Indemnity Matter referred to in the foregoing clause (B) unless and until such Loss (or series of related Losses) equals or exceeds $100,000 and (ii) following May 22, 2026, the Immedica Indemnified Parties shall not be entitled to recover any Loss against Aeglea or any of its Subsidiaries (other than by means of a Milestone-Setoff) with respect to an Excluded Indemnity Matter referred to in the foregoing clause (A), except to the extent an Indemnification Claim in respect of such Loss was first made prior May 22, 2026 (it being understood, for the avoidance of doubt, that nothing in this proviso shall limit or otherwise affect an Immedica Indemnified Party’s rights to recover Losses at any time with respect to an Excluded Indemnity Matter by means of a Milestone-Setoff). No claim for indemnification under this Article VII by the Immedica Indemnified Parties shall be asserted against, and the Immedica Indemnified Parties shall not be entitled to indemnification from, Aeglea or any of its Subsidiaries for a claim for indemnification under Article VII (other than in respect of the Excluded Indemnity Matters, but subject to the proviso in this Section 7.6) except to the extent such recourse is limited to Milestone Set-Offs. For the avoidance of doubt, nothing in this Section 7.6 shall limit or otherwise affect Immedica’s right to specific performance as provided in Section 9.3.

Section 7.7 Exclusive Remedy. Following the Closing Date, the sole and exclusive remedy of any Indemnified Parties for any Losses (including any Losses from claims for breach of contract, warranty, tortious conduct (including negligence) or otherwise and whether predicated on common Law, statute, strict liability or otherwise) that each Party may at any time suffer or incur, or become subject to, as a result of, or in connection with this Agreement, including any inaccuracy or breach of any representation and warranty contained in this Agreement by any Party, or any failure by any Party to perform or comply with any covenant or agreement that, by its terms, was to have been performed, or complied with, under this Agreement, shall be indemnification in accordance with this Article VII and any Milestone Set-Off pursuant to Section 1.2(e), except with respect to any claim based on intentional fraud or willful misconduct or claims for specific performance pursuant to Section 9.3, injunction or other equitable relief. For the avoidance of doubt, the limitations set forth in this Article VII shall not apply to claims for intentional fraud or willful misconduct.
