  	 	5.	PAYMENT AND LAPSE OF AWARDS


   

  		5.1	Except as provided in the Country Annexes, an Award shall be settled and paid out only in accordance with Rule 6.


   

  		5.2	Where a Participant ceases to be an employee or service provider at any time:

  		5.2.2	for any other reason, any Awards shall to the extent not already Vested lapse forthwith, without consideration therefor, while the Vested proportion shall
          continue in effect subject to these Rules, and shall be settled and paid on a Liquidity Event in accordance with Rule 6.


   

  		5.3	Where an Award continues to be in effect under Rule 5.2.2, an Award shall lapse and cease to be exercisable forthwith, without consideration therefor, if
          the Administrator reasonably determines that the Participant is in material breach of the terms of any settlement agreement relating to the termination of his employment or any other agreement with any Service Recipient (or any affiliate
          thereof), or has otherwise breached express or implied duties of confidentiality owed to the Company (or any of its affiliates) or the Service Recipient.

          to the date of the Liquidity Event) shall automatically Vest in full.


  

   

  
 7
  
    
      
 

  

  
    	
            

            

          	
            6.2

          	
            Subject to Rules 6.3 and 6.4 and the Country Annexes, within 30 days following the Liquidity Event, each Participant shall be entitled to
              be paid by the Service Recipient a Cashout Amount calculated as follows:

          


  

  

  

  Cashout Amount = Z x (Closing Value less Strike Price)

   

   

  where Z is the number of Notional Shares or Shares in relation to which the Award has Vested. Any Relevant Liabilities arising thereon shall be
    deducted prior to payment.

   

  		6.3	Where the Liquidity Event takes the form of an IPO, the Administrator may in its discretion determine that Awards or parts thereof shall following Vesting
          be satisfied by transferring or procuring the issue to the Participant of Shares (or, if applicable, common shares of the public company that is the successor to the Company) with a fair market value equivalent to the Cashout Amount, less any Relevant Liabilities, provided that such Shares (or, if applicable, such common shares of the public company that is the successor to the Company) may be subject to limitations and transfer
          restrictions as the Administrator may in its discretion determine. In connection with an IPO, the Administrator may also determine to continue the Awards on such terms and conditions as it reasonably determines and in a manner consistent with
          applicable law.


   

  		6.4	Where the consideration on a Liquidity Event is deferred or contingent (which shall include an IPO where only
          part of the Fund’s holding is disposed of), the Administrator may in its discretion apply either or both of the following methods of payment:


   

  		6.4.1	determine a value of the Company based on the implied value of such deferred and/or contingent consideration, and make payments immediately on the basis that such value is
          included in the Closing Value for the purposes of Rule 6.2; or


   

  		6.4.2	make an initial payment under Rule 6.2 based on sums initially paid, followed by additional payments in the event that the deferred and/or contingent consideration is
          subsequently paid.


   

  	 	7.	VARIATION OF CAPITAL


   

  		7.1	In the event of any variation of the share capital of the Company (whenever effected) by way of capital increases or reductions, or share splits, payment of a special or
          extraordinary dividend, or otherwise, by the Company, the Strike Price and the number of Notional Shares or Shares, as applicable, in respect of which any Award granted under the Plan shall Vest may be adjusted by the Administrator in such manner
          as it sees fit.


   

   

  
 8
  
    
      
 

  

  		7.2	In the event of a group reorganization (including, without limitation, the formation of a new parent company), the Administrator may determine that the Notional Shares or
          Shares, as applicable, in which any Award granted under the Plan shall Vest, shall relate to the same or an adjusted number of shares of another company, provided that such shares have substantially an equivalent fair market value.


   

  		7.3	As soon as reasonably practicable after making any adjustment under Rules 7.1 or 7.2 above, the Administrator shall give notice in writing thereof to each Participant.


   

  	 	8.	PARTICIPATION SEPARATE FROM EMPLOYMENT OR SERVICE


   

  It shall be a condition of participation in the Plan that in the event of a Participant ceasing to be an employee or service provider (for whatever reason), he shall not, subject to any provision of applicable law to the contrary, be entitled to any compensation whatsoever by reason of any termination or alteration of rights or expectations under the Plan
    whether such compensation is claimed by way of damages for wrongful dismissal or breach of contract or for loss of office or otherwise howsoever. Participation in this Plan by a Participant is a matter entirely separate from any pension right or
    entitlement he may have and from his terms or conditions of employment or service and participation in this Plan shall in no respect whatever affect in any way a Participant’s pension rights or entitlement or terms or conditions of employment or
    service. As a condition to participation, each Participant acknowledges and agrees that the grant of an Award hereunder is in full satisfaction of the Service Recipient’s (or any affiliate of the Service Recipient) commitment to grant an equity-based
    award under an offer letter or other terms of employment or service. Any amounts paid or payable hereunder shall not constitute salary, wages or other remuneration or compensation, for purposes of any other
    benefit plan of any Service Recipient (or its affiliates).

   

  	 	9.	TAX AND SOCIAL SECURITY


   

  		9.1	The Participant is responsible for reporting the receipt of any income under the Plan, however made, to the appropriate tax authority in accordance with applicable law.


   

   

  
 9
  
    
      
 

  

  Payments made under this plan to Participants other than employees shall be deemed to be inclusive of VAT, if any.

   

  The grant, vesting or other relevant event of an Award will be subject to any withholding that may be necessary of or on account of a Participant’s tax
    liability and employee social security contribution liability in respect of that Award. The Company and the Service Recipient will be entitled to deduct or withhold a sufficient portion of the value otherwise due to be released to the Participant to
    satisfy any withholding liability. Without limitation, where withholding is required, withholding arrangements may include the sale of any Shares subject to an Award on behalf of a Participant and/or deductions from salary and/or bonus payments and/or
    fees, or require a payment from the Participant before settlement of the Award. If required in order to comply with any applicable laws, the Participant may be required to personally pay such sums as may be required for purposes of meeting the
    withholding obligations of the Company or the Service Recipient.

   

  The Company and the Service Recipient shall have the right to notify the tax authorities of the grant and payment of an Award and submit the tax
    authorities all documents in connection with the grant and payment of an Award, if so required by law.

   

  		9.2	The Company and the Service Recipient will be entitled to block or prohibit the release of a sufficient number of Shares otherwise due to be released or to offset any claims
          towards the Participant if the Participant has any outstanding obligations (whether in connection with the Plan or otherwise arising in the course of the Participant’s employment or service contract), until the Participant has satisfied such
          outstanding obligations.


   

  	 	10.	ADMINISTRATION, AMENDMENT AND TERMINATION


   

  		10.1	The Plan shall be interpreted and administered by the Administrator whose decision on all matters of interpretation and administration shall be final and
          binding on all parties.


   

  		10.2	There is no obligation for uniformity of treatment of Participants by the Administrators (either individually or collectively).


   

   

  
 10
  
    
      
 

  

  		10.3	Except with respect to Rules 2.3 and 2.4, the Administrator may from time to time make amendments to these Rules and the accompanying Country Annexes, provided that:


   

  		10.3.1	no amendment may detrimentally and materially affect a Participant as regards any Award held by him on the date of the amendment unless being made with the Participant’s
          consent, provided, however, that the foregoing restriction in this clause 10.3.1 shall not apply to any amendment required to comply with any applicable statute, regulation or enactment; and


   

  		10.3.2	written notice of any material alteration made in accordance with this Rule 10 shall be given to all affected Participants.


   

  		10.4	The Administrator may at any time resolve to terminate this Plan, in which event no further Awards shall be granted but the provisions of this Plan shall continue in force in
          relation to Awards subsisting prior to that date.


   

  		10.5	The Plan is intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant by the Service Recipient, nothing
          contained herein shall give any such Participant any rights that are greater than those of a general unsecured creditor of the Service Recipient. No trust fund shall be established for the payment or provision of benefits hereunder. The
          obligation to make payments under the Plan shall be contractual only and all such payments shall be made from the general assets of the Service Recipient.


   

  		10.6	Any notice to be given pursuant to the terms of these Rules must be given in writing to the party due to receive such notice at (in the case of the Company) its registered
          office address from time to time or (in the case of an individual) his address (including email address) as notified to the Company from time to time. Notice must be delivered personally or sent by post or electronic transmission and shall be
          deemed to be given in the case of personal delivery on delivery and in the case of posting (in the absence of evidence of earlier receipt) within 48 hours after posting (six days if sent by air mail) and in the case of electronic transmission two
          hours after sending.


   

   

  
 11
  
    
      
 

  

  		10.7	By accepting an Award, a Participant consents to the collection, holding, processing and transfer of the Participant’s Personal Data by any company in the Group for all
          purposes connected with the Awards, including


   

  		10.7.1	the transfer of the Participant’s Personal Data to the Company’s registrars or brokers or any administrators of the Company’s share incentive arrangements;
          and


   

  		10.7.2	the transfer of the Participant’s Personal Data to a prospective buyer of the Company or of any company in the Group or business unit which employs the
          Participant, and the prospective buyer’s professional advisers, provided that those persons irrevocably agree to use the Participant’s Personal Data only in connection with the proposed transaction and in accordance with the data protection
          principles set out in the relevant data protection legislation

        


   

   

  and, for the avoidance of doubt, any such permitted transfers shall include transfers of Personal Data to recipients located outside the EEA.

  

  

  		10.8	The Plan and its terms may be disclosed to (potential) investors in the Company or acquirers of the Company or all or parts of its assets, to underwriting
          banks, and in any prospectuses or other disclosure materials.


   

  		10.9	Except as otherwise provided in the Country Annex, the Rules and the Plan shall in all respects be governed by the laws of Switzerland.

  COUNTRY ANNEX FOR ADC THERAPEUTICS (UK) LIMITED  

  (“UK COMPANY”)

   

  The Rules governing awards to employees and service providers of the UK Company shall be as per the Plan, with the following differences:

   

  1.       Unless the Administrator determines otherwise in its discretion, Awards granted by the UK Company shall be granted over Notional Shares only,
    albeit that they may be satisfied in Shares on an IPO in accordance with Rule 6.3. The Plan, including in particular the definition of “Award” and Rule 3 shall be read accordingly.

   

  2.       The Administrator of the Plan shall be the UK Company. Under no circumstances shall payments be made under the Plan to UK-resident employees of
    the UK Company by any person other than the UK Company.

   

  COUNTRY ANNEX FOR ADC THERAPEUTICS AMERICA, INC.

  AND ANY U.S. TAXPAYER PARTICIPANTS

   

  The Rules governing awards to employees and service providers who are U.S. taxpayers subject to Section 409A of the U.S. Internal Revenue Code of 1986, as
    amended (together with regulations and published guidance thereunder, the “Code”) shall be as per the Plan, with the following differences:

   

  		1.	Awards hereunder are intended to constitute non-qualified stock options having a Strike Price no less than fair market value of a Share on the date of grant
          as determined under Code Section 409A, and those Awards shall be, subject to the terms of the Plan and this Annex, exercisable for Shares of the Company. All interpretations and determinations hereunder shall be made on a basis consistent with
          such intent. Any adjustment to an Award under Rule 7 shall be made in a manner intending to comply with Code Section 409A.


   

  		2.	The definition of “Award” means a right (for the time being subsisting) which following exercise (as applicable)



          and satisfaction of any strike price or, if earlier, a Liquidity Event will entitle the holder to receive Shares or a cash amount equal to the difference (if positive) between the Closing Value and the Strike Price, multiplied by the
          number of Vested Notional Shares or Shares subject to an Award.


   

   

  
 13
  
    
      
 

  

  	 	3.	The Plan is amended to add the following clause 6.4.3:


   

  		6.4.3	In each case above, no such payment shall be made to a Participant if such payment would result in adverse tax treatment under applicable law (including, without limitation,
          U.S. Internal Revenue Code Section 409A) or a material modification of such Award. Any such payment shall be made in a manner consistent with the intent that such Awards are intended to avoid such adverse tax treatment.


   

  		4.	This Plan is not a retirement or welfare benefit plan, and is not intended and shall not be construed to be a retirement or welfare benefit plan. Further,
          this Plan is not intended to defer the receipt of payments to the termination of a Participant’s employment or beyond, and shall not be governed by or subject to the federal Employee Retirement Income Security Act of 1974, as amended (“ERISA”).



          All interpretations and determinations hereunder shall be made on a basis consistent with the Plan’s status as not an employee benefit plan subject to ERISA.


   

  		5.	Notwithstanding any other provision of this Plan, this Plan is intended to be exempt from Section 409A and Section 457A of the Code, and shall at all times
          be interpreted in accordance with such intent. In no event will the Company or its affiliates, or their members or affiliates, or their respective employees, directors, officers, agents, representatives, attorneys, equityholders, principals,
          members, managers or affiliates have any liability for any failure of the Plan to satisfy the requirements of, or be exempt from, Code Section 409A and/or Code Section 457A, and such parties do not guarantee that the Plan complies with, or is
          exempt from, Code Section 409A and/or Code Section 457A. No Participant shall have a binding right to distributions made to it in error. Each payment payable hereunder is and shall be deemed a payment in a series of separate payments for all
          purposes of Code Section 409A. All references to termination of service (and similar terms) shall mean a “separation from service” within the meaning of Treasury Regulation 1.409A-l(h).


   

  		6.	The terms of participation of any U.S. taxpayer in respect of his Award under the Plan will be set forth in an Award Letter, the terms of which shall
          control in the event of any inconsistency with the terms of the Plan.


   

  		7.	The right of a U.S. taxpayer Participant to exercise his Award and receive Shares shall be subject to the satisfaction of all requirements of applicable
          law concerning the Company, including, without limitation, obtaining board and shareholder approval to issue such Shares. In the event the Participant cannot, under applicable law, receive Shares upon exercise, then the Company can either (i)
          defer the Participant’s exercise to a time when delivery of Shares would not violate applicable law, or (ii) settle such Award in cash.

  		8.	Any Shares delivered to a U.S. taxpayer Participant prior to a Liquidity Event shall be subject to a right of repurchase by the Company (or its
          affiliates), which may be assigned, as more fully set forth in an Award Letter.


   

  		9.	As a condition to the receipt of Shares following exercise of any option awarded under the Plan, a U.S. taxpayer Participant agrees to execute such
          documents as the Administrator shall, in its reasonable discretion, determine, including without limitation any lock-up agreement or shareholders’ agreement.


   

  		10.	In the event that any payment or benefit provided under the Plan would, based on the determination of counsel or the accountants for the Company, not be
          deemed to be deductible in whole or in part in the calculation of federal income tax of the Company, or any other person making such payment, by reason of Section 280G of the Code or result in the imposition of taxes under Code Section 4999 to
          the Participant, the aggregate payments, coverages or benefits provided under the Plan and any other arrangement on account of a “change in control” shall be reduced to one dollar less than the “safe harbor” level under Section 280G so that the
          entire amount that is paid or provided to the Participant shall be deductible notwithstanding the provisions of Section 280G of the Code; provided, however, that the Company agrees to use commercially reasonable efforts to obtain
          shareholder approval of any payments or benefits in excess of the safe harbor level in accordance with Q&A #7 of Section 280G of the Code so that there will be no such loss of deductibility under Section 280G or imposition of tax under
          Section 4999, and in connection with such efforts to obtain shareholder approval, Plan Participants agree to waive any amounts in excess of such safe harbor level. All determinations regarding the manner of cutback shall be reasonably determined
          by the Plan Administrator in a manner that does not violate Section 409A of the Code, as applicable.
