(ii) The Selling Shareholders, severally and not jointly, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act to the extent and in the manner set forth in Section 12(a)(i) above; provided, however, that each Selling Shareholder shall be liable only to the extent that such untrue statement or alleged untrue statement or such omission or alleged omission has been made in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, a road show, or the Prospectus or any amendment or supplement thereto, or any Written Testing-the-Waters Communication based on the Selling Shareholder Information relating to such Selling Shareholder; provided, further, that the liability of each Selling Shareholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the aggregate Public Offering Price of the Shares sold by such Selling Shareholder under this Agreement.

(b)

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Shareholders, the Company’s directors, the Company’s officers who sign the Registration Statement and each person, if any, who controls the Company or any Selling Shareholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter and from the Selling Shareholder to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus, road show or the Prospectus or any amendment or supplement thereto, or any Written Testing-the-Waters Communication, it being understood that the only such information is the Underwriter Information.

(c)

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 12(a), 12(b) or 12(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred, documented fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed in writing to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the persons named as attorneys in fact for the Selling Shareholders under the Powers of Attorney. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)

To the extent the indemnification provided for in Section 12(a), 12(b) or 12(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 12(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 12(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by each Seller on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each Seller and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of each Seller on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by a Seller or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 12 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The liability of each Selling Shareholder under the contribution agreement contained in this paragraph shall be limited to an amount equal to the aggregate Public Offering Price of the Shares sold by such Selling Shareholder under this Agreement.

(e)

The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 12 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 12(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 12(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 12, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 12 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f)

The indemnity and contribution provisions contained in this Section 12 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, by or on behalf of any Selling Shareholder or any person controlling any Selling Shareholder, or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

13.

Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and prior to the Closing Date or any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, the SIX Swiss Exchange, NYSE, the NYSE MKT, or the Nasdaq Global Market (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States or Switzerland shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal, New York State, in Switzerland or relevant foreign country authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

14.

Effects of Termination on Shares.

(a)

If, after application and registration of the Firm Capital Increase with the Commercial Register of the Canton of Vaud pursuant to Section 6(c), prior to the Closing Date, this Agreement is terminated pursuant to Section 13, or if the delivery of the Firm Shares or Applicable Additional Shares to Xxxxxx Xxxxxxx & Co. LLC acting on behalf and for the account of the several Underwriters is not completed on the Closing Date or the relevant Option Closing Date, as the case may be (each, an “Event of Non-Completion”), and unless the Company and the Representatives, acting on behalf of the several Underwriters, otherwise agree within ten calendar days after the Event of Non-Completion, then:

(i)

the Company shall have a call option pursuant to Section 14(b);

(ii)

if the call option is not exercised, the Representatives acting on behalf of the several Underwriters shall have a put option against the Company pursuant to Section 14(c);

(iii)

if the put option is not possible for legal reasons or insufficient to dispose of the Firm Shares or if such put option is not exercised within the deadline set forth in Section 14(c), the Company shall effect a capital reduction pursuant to Section 14(d); and

(iv)

if the capital reduction is not effected in accordance with Section 14(d), the Underwriters may sell the Firm Shares in the market as provided in Section 14(e).

(b)

Call Option.

(i)

The Company, acting on its own behalf or on behalf of third parties, shall have the right (the “Call Option”) to request in writing that Xxxxxx Xxxxxxx & Co. LLC, acting on behalf of the several Underwriters, delivers the Firm Shares to an account specified by the Company against payment of an amount representing the Aggregate Firm Capital Increase Amount plus expenses of the Representatives as set out in Section 14(f). The Call Option shall expire on the tenth calendar day after the Event of Non-Completion.

(ii)

An acquisition of the Firm Shares by the Company for its own account shall only be permitted if the Company has delivered evidence to the Representatives reasonably satisfactory to the Representatives that the Company has sufficient freely available reserves to acquire the Firm Shares under this Section 14(b) or, alternatively, that the Company has entered into arrangements with a third party other than any of the Company’s subsidiaries ensuring for the immediate on-sale of the Firm Shares to such third party, at no less than an amount representing the Aggregate Firm Capital Increase Amount plus expenses of the Representatives as set out in Section 14(f), on the date of acquisition of the Firm Shares by the Company.

(c)

Put Option.

(i)

Following the expiry of the Call Option pursuant to Section 14(b), the Representatives, acting on behalf of the several Underwriters, shall have an option (the “Put Option”) to require the Company, subject to article 659 CO, to purchase all Firm Shares entered in the Commercial Register of the Canton of Vaud at a purchase price representing the Aggregate Firm Capital Increase Amount plus expenses of the Representatives as set out in Section 14(f), within ten (10) calendar days after receipt of a notice in writing addressed to the Company from the Representatives, stating that the Representatives exercises the Put Option.

(ii)

The notice in which the Representatives exercise the Put Option shall specify the date on which the Representatives will deliver the Firm Shares to the Company against direct payment therefor, and shall contain detailed instructions regarding payment and delivery of the Firm Shares and amount payable (including satisfactory details regarding the costs claimed according to Section 14(f) subject to an agreement to the contrary by the Representatives with the Company).

(d)

Capital Reduction.

(i)

If the Put Option is not exercised within the deadline set forth in Section 14(c) or exercise or settlement of the Put Option is not possible for legal reasons or insufficient to dispose of the Firm Shares the Company shall immediately call a shareholders’ meeting and table the reduction of the share capital. Such shareholders’ meeting shall take place no later than sixty (60) calendar days after the Event of Non-Completion. The Representatives acting on behalf of the several Underwriters, will vote in favor of a reduction of the issued and outstanding share capital of the Company (the “Capital Reduction”) by cancellation of the Firm Shares entered in the Commercial Register of the Canton of Vaud against repayment of an amount representing the Aggregate Firm Capital Increase Amount plus expenses of the Representatives as set out in Section 14(f). Prior to such shareholders’ meeting, the Company shall use its best efforts to cause its auditors to confirm in writing, pursuant to article 732 para. 2 CO, that the claims of the Company’s creditors are fully covered notwithstanding the Capital Reduction, provided that if such confirmation is not made by the auditors prior to such meeting, the meeting shall be cancelled. The Company shall use its best efforts to cause its shareholders to vote in favor of the Capital Reduction.

(ii)

At the earliest possible date, and subject to statutory law, the Capital Reduction shall be consummated by registration in the Commercial Register of the Canton of Vaud. The proceeds of the Capital Reduction, being an amount representing the Aggregate Firm Capital Increase Amount plus expenses of the Representatives as set out in Section 14(f), shall be paid (for value on the date of the entry in the Commercial Register of the Canton of Vaud) in cash to Xxxxxx Xxxxxxx & Co. LLC, acting on behalf of the several Underwriters.

(iii)

Upon consummation of the Capital Reduction, the Company shall deregister the Firm Shares in its book of uncertificated securities (Wertrechtebuch) to reflect the number of Common Shares registered with the Commercial Register of the Canton of Vaud.

(e)

Sale of Firm Shares.

In addition, if an Event of Non-Completion occurs and,

(i)

the Company fails to acquire or cause a third party to acquire the Firm Shares in accordance with Section 14(b) within ten (10) calendar days after the Event of Non-Completion; and

(ii)

in the event and to the extent the Put Option has not been exercised within the deadline set forth in Section 14(c) and settled or the exercise or settlement of the Put Option is not possible for legal reasons or insufficient to dispose of the Firm Shares; and

(iii)

the Capital Reduction has not been resolved by the shareholders’ meeting of the Company within sixty (60) days after the Event of Non-Completion, or such longer period as may be agreed between the Company and the Representative;

then the Representatives, acting on behalf of the several Underwriters, are entitled to sell any or all Firm Shares on the open market on terms which the Representatives deem fit under the circumstances. The difference between the proceeds of such sale and an amount representing the Aggregate Firm Capital Increase Amount plus costs and expenses pursuant to Section 14(f) reasonably incurred by the Representatives in connection with the sale, if any, shall be transferred to the Company.

(f)

Costs; Indemnity.

(i)

The Company shall bear (A) all costs directly incidental to the Capital Reduction, including but not limited to notarization costs, costs of the Commercial Register and costs of publication of the Capital Reduction and (B) the costs of the Representatives reasonably incurred in connection with the Call Option, the Put Option or the Capital Reduction, as applicable (including but not limited to (x) taxes, (y) interest at a rate of the higher of zero or the 3-month CHF LIBOR, calculated on a 30/360 basis, accruing from the Event of Non-Completion until the payment of proceeds to the Representatives, acting on behalf of the several Underwriters, and (z) reasonable out of pocket expenses of the Representatives and their counsel).

(ii)

The Company further undertakes to indemnify the Representatives and their affiliates for, and to hold the Representatives and their affiliates harmless from, any reasonable costs, expenses, third party claims and liabilities, actual or contingent, that may be incurred by or made against the Representatives and their affiliates in connection with the Capital Reduction.

15.

Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one‑tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non‑defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 15 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one‑tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives, the Company and the Selling Shareholders for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non‑defaulting Underwriter, the Company or the Selling Shareholders. In any such case either the Representatives or the relevant Sellers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one‑tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of any Seller to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any Seller shall be unable to perform its obligations under this Agreement, the Sellers will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all reasonably incurred and documented out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder; provided that, the Sellers shall not be required to reimburse the Underwriters in the event any such termination is effected pursuant to Section 13(i), 13(iii), 13(iv) or 13(v). In the event any such termination is effected after the Closing Date but prior to any settlement date for the Additional Shares, the Sellers will only reimburse the Underwriters for all reasonably incurred and documented out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters after the Closing Date in connection with the proposed purchase of such Additional Shares.

16.

Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(a)

The Company and each Selling Shareholder acknowledge that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, any of the Selling Shareholders or any other person, (ii) the Underwriters owe the Company and each Selling Shareholder only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, (iii) the Underwriters may have interests that differ from those of the Company and each Selling Shareholder and (iv) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. The Company and each Selling Shareholder waive to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

(c)

Each Selling Shareholder further acknowledges and agrees that, although the Underwriters may provide certain Selling Shareholders with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to any Selling Shareholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

Submission to Jurisdiction. The Company and each of the Selling Shareholders irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York (the “Specified Courts”) over any suit, action or proceeding arising out of or relating to this Agreement, the Prospectus, the Registration Statement or the offering of the Shares (each, a “Related Proceeding”). The Company and each of the Selling Shareholders irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any Related Proceeding brought in such a court and any claim that any such Related Proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company and each of the Selling Shareholders has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company and each of the Selling Shareholders irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

22.

Appointment of Agents for Service. The Company hereby irrevocably appoints ADC Therapeutics America, Inc., with offices at 000 Xxxxxxxx Xxxxxx, 0xx Xxxxx, Xxxxxx Xxxx, Xxx Xxxxxx, 00000 as its agent for service of process in any Related Proceeding and agrees that service of process in any such Related Proceeding may be made upon it at the office of such agent. The Company waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. The Company represents and warrants that such agent has agreed to act as the Company’s agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect. Each of the Selling Shareholders herby irrevocably appoints Corporation Service Company, with offices at 0000 Xxxxxx xx xxx Xxxxxxxx, Xxxxx 000, Xxx Xxxx, XX 00000 as its agent for service of process in any Related Proceeding and agrees that service of process in any such Related Proceeding may be made upon it at the office of such agent. Each of the Selling Shareholders waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. Each of the Selling Shareholders represents and warrants that such agent has agreed to act as the Selling Shareholders’ agent for service of process, and each of the Selling Shareholders agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect.

23.

Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company or any Selling Shareholder with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company and each of the Selling Shareholder agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company or the relevant Selling Shareholder an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

24.

Taxes. If any sum payable by the Company or a Selling Shareholder to the Underwriter under this Agreement is subject to deduction or withholding, under Swiss law, the sum payable to the Underwriter under this Agreement shall be increased to such sum as will ensure that the Underwriter shall be left with the sum it would have had in the absence of such deduction or withholding, provided that no such additional amounts shall be payable as a result of any taxes imposed on the Underwriter by virtue of the Underwriter having or being deemed to have a permanent establishment in, or other connection with, Switzerland other than solely by reason of execution and delivery of this Agreement, the performance by the Underwriter of its obligations hereunder, the consummation of the transactions contemplated hereby and the enforcement of the rights with respect to the foregoing.

25.

Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.
