(a) all Patents and Trademarks set forth on Schedule 1.1(a), and all Know-How owned by Seller and its Affiliates that
primarily relates to the Punctal Plug Program and which is in the possession of Sellers and its Affiliates (collectively, the “Purchased IP”); 
 (b) all rights of Seller and its Affiliates under all contracts set forth on Schedule 1.1(b), as such contracts may have been amended prior to the date hereof (the “Assumed

consent unless such expenses are reimbursed by Buyer. 
 (d) To the extent any Assumed Contract does not permit assignment or
transfer by Seller to Buyer pursuant to the Transaction Documents without the consent of a third party, and such consent is not obtained prior to Closing, Buyer shall waive the obligation to obtain such consent prior to Closing. In such case, Seller
shall (i) use commercially reasonable efforts to obtain such consent promptly after the Closing (subject to Section 4.6(c)), and (ii) until the earliest of: (a) the date all such consents are obtained, (b) the date all such
Assumed Contracts expire or are terminated or (c) the date which is [***] from the Closing, Seller and Buyer shall cooperate, in all commercially reasonable respects, to make the benefits of such Assumed Contract available to Buyer, to the

breach of such Assumed Contract, enforce the terms and conditions of such Assumed Contract if requested by Buyer at Buyer’s expense.

Asset, Seller shall cooperate in 

  
 15 









 
good faith with Buyer to determine whether such Omitted Asset should have been transferred to Buyer as a Purchased Asset, and if Seller agrees that such Omitted Asset should have been transferred
to Buyer at Closing, Seller shall either (i) transfer and assign the Omitted Asset to Buyer or (ii) otherwise make the benefits of such Omitted Asset available to Buyer. Any consideration payable by Buyer for any such Omitted
Assets shall be deemed to have already been included in the Purchase Price for the Purchased Assets. Notwithstanding the foregoing, Buyer shall be responsible for payment of any fees or costs associated with the transfer of any Omitted Assets.

debts generally, (ii) amend its certificate of incorporation to remove, modify or limit in any way the prohibition contained in Section             thereof [which shall have the same

Section 4.8 Transition Services. 
 (a) For a period of [***] from and after the Closing Date, Seller agrees to provide, or to cause its Affiliates to provide, the transition services set forth on Schedule 4.8 hereto (the
“Transition Services”). For greater certainty and notwithstanding any provision of this Agreement to the contrary, Seller shall not have any responsibility to provide (i) any service to the extent that the Seller does not have
qualified personnel available to perform such service or to the extent that the provision of such service would require the Seller to engage any additional employees or consultants, or (ii) provide services that Seller’s employees did not
provide immediately before the Closing. 
 (b) Buyer agrees to reimburse Seller for all reasonable costs to Seller of providing
the Transition Services, including the cost of employee wages and compensation on a full-time equivalent basis in respect of time spent providing the Transition Services and all out-of-pocket expenses reasonably incurred by Seller in connection with
the provision of the Transition Services. 
 (c) Not later than twenty-one (21) days after the last day of each fiscal
month of Seller during which Seller provides Transition Services to Buyer (or, if such date is not a Business Day, then on the immediately succeeding Business Day), Seller shall provide to Buyer an invoice for the preceding month’s Transition
Services, which shall list (i) the Transition Services provided by Seller to Buyer for such month, and (ii) the charges for such Transition Services and shall be accompanied by documentation with respect to the out-of-pocket expenses in
respect of which Seller is claiming reimbursement. The amount stated in such invoices shall be paid by Buyer in full within thirty (30) days of the issuance of the invoices (or, if such date is


  
 16 









 
not a Business Day, then on the immediately succeeding Business Day) to an account designated by Seller, except to the extent such amount shall be the subject of a good faith dispute between
Buyer and Seller.

Closing. 
 Section 5.2 Obligation to Indemnify. 

(a) Indemnification by Seller. Subject to the limitations set forth in this Article V and Section 4.8(d), Seller agrees
to indemnify, defend and hold harmless Buyer and its directors, managers, officers, employees, successors, permitted assigns, agents and representatives (collectively, the “Buyer Indemnitees”), from and against all Losses resulting
from or related to: 
 (i) any breach or inaccuracy of any of the representations and warranties of Seller contained in this
Agreement or any other Transaction Document; 
 (ii) any non-compliance with or breach of any covenant or agreement of Seller
contained in this Agreement or any other Transaction Document; and 
 (iii) any Excluded Liability. 

(b) Indemnification by Buyer. Subject to the limitations set forth in this Article V, Buyer agrees to indemnify, defend and

 (iii) any Assumed Liability. 

Section 5.3 Indemnification Procedures. 
 (a) Any Buyer Indemnitee or Seller Indemnitee making a claim for indemnification pursuant to this Article V (an “Indemnified Party”) must give the other Party from whom
indemnification is sought (an “Indemnifying Party”) written notice of such claim (a “Claim Notice”) promptly after the Indemnified Party receives any written notice of any Proceeding against or involving
the Indemnified Party by a Governmental Authority or other third party, or otherwise discovers the liability, obligation or facts giving rise to such claim for indemnification (“Claim”); provided that the failure to notify or delay
in notifying an Indemnifying Party will not relieve the Indemnifying Party of its obligations pursuant to this Article V, except to the extent (and only to the extent) that such failure actually harms the


  
 18 









 
Indemnifying Party. Such Claim Notice must contain a description of the Claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known or reasonably
ascertainable at such time; provided that such amount or estimated amount shall not be conclusive of the final amount, if any, of such Claim). Notwithstanding the foregoing, any claim for a breach of a representation or warranty or covenant must be
delivered prior to the expiration of the applicable survival term set forth in Section 5.1. 
 (b) With respect to the
defense of any Claim against or involving an Indemnified Party in which a Governmental Authority or other third party in question seeks recovery of a sum of money for which a Claim Notice is provided (i) the Indemnifying Party shall have the
right to participate in the defense of each Claim, (ii) the Indemnified Party shall fully cooperate with the Indemnifying Party and provide access to any and all applicable documents and other information and Persons reasonably requested by the
Indemnifying Party; provided that the Indemnified Party shall have no obligation to disclose any documents or other information to the extent such disclosure in the Indemnified Party’s reasonable judgment may adversely affect the
attorney-client privilege or work product protections related to such documents or other information and (iii) at its option an Indemnifying Party may at its own expense assume the defense and appoint as lead counsel of such defense any legal
counsel selected by the Indemnifying Party. 
 (c) If the Indemnifying Party assumes the defense of any Claim pursuant to
Section 5.3(b)(iii), the Indemnified Party will be entitled to participate in the defense of such Claim and to employ counsel of its choice for such purpose at its own expense; provided that the Indemnifying Party will bear the reasonable fees
and expenses of such separate counsel incurred prior to the date upon which the Indemnifying Party assumes control of such defense; provided, further, that the Indemnifying Party will not be entitled to assume control of the defense of such claim,
if: 
 (i) the Indemnifying Party fails to elect in writing to assume the defense of the Claim pursuant to
Section 5.3(b)(iii) within twenty (20) calendar days of receipt of the applicable Claim Notice, 
 (ii) a
conflict of interest exists or could reasonably be expected to arise which, under applicable principles of legal ethics, could reasonably be expected to prohibit a single legal counsel from representing both the Indemnified Party and the
Indemnifying Party in such Proceeding, or 
 (iii) a court of competent jurisdiction rules that the Indemnifying Party has
failed or is failing to prosecute or defend vigorously such claim; 
 provided, further, that, in each case, the Indemnified Party shall be
prohibited from compromising or settling any Claim, including, without limitation, any Claim relating to Taxes that could reasonably be expected to have an adverse effect on the Taxes relating to the Purchased Assets in Tax periods (or portions
thereof) beginning after the Closing Date, without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. 

  
 19 









 (d) In the event that the Indemnifying Party assumes the defense of such claim, the
Indemnified Party will cooperate with and make available to the Indemnifying Party such assistance, personnel, witnesses and materials as the Indemnifying Party may reasonably request. Regardless of which Party defends such claim, the other Party
shall have the right at its expense to participate in the defense assisted by counsel of its own choosing. 
 (e) Without the
prior written consent of the Indemnified Party (which shall not be unreasonably withheld or delayed), the Indemnifying Party shall not enter into any settlement of any Claim for which the Indemnifying Party has assumed the defense pursuant to
Section 5.3(b)(iii) if (i) pursuant to or as a result of such settlement, such settlement would result in any liability on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder
or (ii) the settlement involves anything other than monetary damages. If a firm offer is made to settle such claim, which offer the Indemnifying Party is permitted to settle under this Section 5.3, and the Indemnifying Party desires to
accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnified Party to that effect. If the Indemnified Party objects to such firm offer within ten (10) calendar days after its receipt of such notice, the
Indemnified Party may continue to contest or defend such claim and, in such event, the maximum liability of the Indemnifying Party as to such claim shall not exceed such amount of such settlement offer payable by the Indemnifying Party hereunder,
plus other Losses paid or incurred by the Indemnified Party up to the point such notice had been delivered to the Indemnified Party. 
 Section 5.4 Subrogation. After any indemnification payment is made to any Indemnified Party pursuant to this Article V (other than by offset), the Indemnifying Party shall, to the extent of
such payment, be subrogated to all rights (if any) of the Indemnified Party against any third party in connection with the Losses to which such payment relates. Without limiting the generality of the preceding sentence, any Indemnified Party
receiving an indemnification payment pursuant to the preceding sentence (other than by offset) shall execute, upon the written request of the Indemnifying Party, any instrument reasonably necessary to evidence such subrogation rights. 

Section 5.5 Right of Offset. 
 (a) Notwithstanding anything in this Agreement to the contrary, (a) from and after the occurrence of a Triggering Event, Buyer shall be entitled to withhold and set off against any other amounts
otherwise due to Seller hereunder (other than the Initial Payment) any amount as to which Seller is obligated to indemnify Buyer pursuant to this Article V and (b) in the event that Seller brings a Claim against Buyer with respect to any
amounts withheld or set off under this Section 5.5 and such Claim results in the payment by Buyer to Seller of greater than 50% of the amount previously withheld or set off pursuant to this Section 5.5(a), then Buyer shall promptly
reimburse Seller for all reasonable fees and costs (including attorney’s fee) incurred by Seller in bringing such Claim. Such right shall terminate upon the later of (A) the 24 month anniversary of the date hereof, and (B) two
Business Days following the date of resolution of any Claims pending on such 24 month anniversary of the date hereof (the period commencing on the date of a Triggering Event and terminating on such termination date is referred to as the
“Set-Off Period”). 

  
 20 









 (b) If during the Set-Off Period there is a Dispute with respect to any amount as to which
Seller is obligated to indemnify Buyer pursuant to this Article V, in lieu of withholding and setting off an amount pursuant to Section 5.5(a), Buyer shall be permitted to pay such amounts into an escrow account with a nationally recognized
escrow agent, the proceeds thereof (together with interest, if any, accrued in the escrow account) to be paid out in accordance with the settlement of such Dispute, in which case Seller’s right to recover reasonable fees and costs pursuant to
Section 5.5(a) shall not apply. 
 Section 5.6 Indemnification Payments. 

(a) The aggregate liability of Seller for any breach of any representation, warranty, covenant and agreement pursuant to this Agreement,
including Sections 5.2(a)(i) and (ii) of this Agreement, shall be limited to [***]. 
 (b) Buyer Indemnitees shall not be
entitled to indemnification under Section 5.2(a)(i) unless the aggregate amount of all Losses exceeds an amount equal to [***], in which event, subject to the limitations in Section 5.5(a), Buyer Indemnitees shall be entitled to recover
all Losses from Seller, and not just the amount in excess of such amount. 
 (c) Any payment under this Article V shall be
treated as an adjustment to the Purchase Price for all Tax purposes and reported as such by Buyer and Seller on their Tax Returns (except to the extent otherwise required by Applicable Law) and shall be made by wire transfer of immediately
available funds to such account or accounts as the Indemnified Party shall designate to the Indemnifying Party in writing. 

Section 5.7 Insurance Proceeds. The amount of any Losses required to be reimbursed under this Article V sustained by an
Indemnified Party shall be reduced by any amount received by such Indemnified Party with respect thereto under any insurance coverage or from any other Person alleged to be responsible therefore (net of any expenses incurred in recovering such
monies, any deductible and any increase in premiums as a result of such claim); provided, the amount of such reduction shall not exceed the amount of such Losses; provided, further, the Indemnified Party shall be entitled to seek indemnification
pursuant to this Article V for the amount of such Losses net of the amount of such reductions (net of any expenses incurred in recovering such monies, any deductible and any increase in premiums as a result of such claim). The Indemnified Parties
shall use commercially reasonable efforts to collect any amounts available under such insurance coverage and from such other Person alleged to have responsibility. If an Indemnified Party receives an amount under insurance coverage or from such
other Person with respect to Losses sustained at any time subsequent to any indemnification payment pursuant to this Article V, then such Indemnified Party shall promptly reimburse the applicable Indemnifying Party for any payment made or expense
incurred by such Indemnifying Party in connection with providing such indemnification up to such amount received by the Indemnified Party. 
 Section 5.8 Duty to Mitigate. Each Indemnified Party shall be obligated to use its commercially reasonable efforts to mitigate to the fullest extent reasonably practicable the amount of any
Losses for which it is entitled to seek indemnification under this Article V, and the Indemnifying Party shall not be required to make any payment to an Indemnified Party in 

  
 21 









 
respect of such Losses to the extent such Losses arise from the failure of the Indemnified Party to comply with the foregoing obligation. All reasonable costs and expenses incurred in connection
with such mitigation shall be included as indemnifiable Losses to the extent reasonably incurred in an effort to mitigate an indemnifiable Loss. 
 Section 5.9 Remedies. 
 (a) Each Party acknowledges and agrees that
the remedies provided for in this Article V shall be its sole and exclusive remedy with respect to the subject matter of this Agreement. Notwithstanding anything to the contrary contained in the foregoing, nothing herein shall (i) limit the
liability of any Party for fraud or (ii) prevent any Party from seeking the remedies of specific performance or injunctive relief in connection with a breach of a covenant or agreement of any Party contained herein or in any Ancillary
Agreement, subject to Section 6.9. 
 (b) Except as otherwise provided herein, any and all remedies herein expressly
conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The
Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. The Parties accordingly agree that they shall be
entitled to seek a temporary injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any court in New York City, New York, or to seek a permanent injunction
from the Arbitrator in addition to any other remedy to which they are entitled at law or in equity.

agreement of the Parties hereto. 
 Section 6.7 Binding Effect; Benefits. This Agreement shall inure to the benefit

 Section 6.8 Assignability.
This Agreement shall not be assignable by any Party hereto without the prior written consent of the other Party except that (a) Buyer may assign its rights and obligations under this Agreement to any Affiliate of Buyer without the prior written

shall relieve such Party of any of its obligations hereunder; provided, further, no such assignment, or series or assignments, shall result in either (i) Buyer being obligated to pay the Purchase Price or any portion thereof to more than one

assignment contrary to the provisions of this Section 6.8 shall be null and void. To the extent any assignment by Buyer of its rights or obligations hereunder to a person or entity outside the United States or Canada would result in adverse
withholding tax consequences to Seller, Buyer shall pay Seller additional amounts sufficient to put Seller in the position Seller would have occupied but for such transfer or exercise of such rights or obligations, limited to the amount of
withholding pursuant to the applicable reduced withholding tax rate provided for in the applicable income tax treaty, if any, between Canada and the jurisdiction of the party exercising Buyer’s rights or subject to Buyer’s obligations,
provided that the benefits of such treaty are available.

 Section 6.9 Enforcement. 

(a) The Parties recognize that disputes as to certain matters may from time to time arise which relate to either Party’s rights or
obligations hereunder or to the interpretation, performance, breach, or termination of this Agreement (a “Dispute”). It is the objective of the Parties to establish procedures to facilitate the resolution of a Dispute in an
expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to attempt in good faith to resolve any such disagreements and thereafter to follow the procedures set forth in this
Section 6.9 if and when a Dispute arises under this Agreement. 
 (b) Unless otherwise specifically set forth in this
Agreement, a Dispute among the Parties will be resolved as provided in this Section 6.9. Any Disputes relating to this Agreement shall be presented to two (2) independent experts knowledgeable in the subject matter of the Dispute (the
“Independent Experts”), one (1) being selected by Buyer and one (1) being selected by Seller, for resolution. In the event that the Independent Experts cannot resolve the Dispute within forty-five (45) days (or such other
period of time as mutually agreed to by the Parties in writing) of being requested by a Party to resolve a Dispute, such Dispute may be referred to arbitration in accordance with the provisions of Section 6.9(c) by either Party. 

(c) Any unresolved Dispute shall be resolved exclusively by final and binding arbitration in accordance with the Commercial Arbitration
Rules of the American Arbitration Association. Following the satisfaction of the requirements of Section 6.9(b) above, either Party may invoke arbitration of a Dispute by serving on the other Party a written notice of arbitration, which shall
specify with reasonable detail (i) the issue in Dispute, (ii) the claims asserted, and (iii) the remedy sought by the Party invoking arbitration. Each Party shall appoint one arbitrator to arbitrate the subject issue within fifteen
(15) days of the date of the foregoing described notice. If one Party fails or refuses to appoint an arbitrator within such time period, then the first arbitrator appointed shall appoint a second arbitrator. Within fifteen (15) days of the
last of those appointments, the two arbitrators shall appoint a third arbitrator. The arbitrators shall be knowledgeable in the subject matter of the issue in Dispute. Each Party appointing an arbitrator or for whom an arbitrator is appointed shall
bear all costs and expenses associated with that arbitrator, and the cost and expenses associated with the third arbitrator shall be shared equally by the Parties. Any arbitration hearing pursuant to this Section 6.9(c) shall be held in the New
York City, New York area. An award rendered in connection with an arbitration pursuant to this Section 6.9(c) shall be final and binding upon the Parties. The Parties agree and consent that the arbitral award shall be conclusive proof of the
validity of the determinations of the arbitrations set forth in the award, and any judgment upon such an award may be entered and enforced in any court of competent jurisdiction. 

(d) THE PARTIES HEREBY IRREVOCABLY WAIVE ANY RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO DISPUTES, INCLUDING WITHOUT LIMITATION
ANY RIGHT TO TRIAL BY JURY AS TO THE MAKING, EXISTENCE, VALIDITY, OR ENFORCEABILITY OF THE AGREEMENT TO ARBITRATE.

Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other
