       Section 2.05. Evidence of Compliance with Conditions Precedent. The Guarantor and Holdings shall provide to the Guarantee Trustee such
evidence of compliance with any conditions precedent, if any, provided for in this Guarantee that relate to any of the matters set forth in Section 314(c) of the Trust Indenture Act. Any certificate or opinion required to be given by an officer
pursuant to Section 314(c)(1) may be given in the form of an Officers’ Certificate and shall include: 


        (a) a statement that each officer signing the Officers’ Certificate has read the covenant or condition and the definition relating
    thereto; 

        (b) a brief statement of the nature and scope of the examination or investigation undertaken by each officer in rendering the Officers’ Certificate; 

        (c) a statement that each such officer has made such examination or investigation as, in such officer’s opinion, is necessary to enable
    such officer to express an informed opinion as to whether or not such covenant or condition has been complied with; and 

        (d) a statement as to whether, in the opinion of each such officer, such condition or covenant has been complied with. 




       Section 2.06. Events of Default; Waiver. The Holders of a Majority of the Preference Shares may, by vote, on behalf of the Holders of all of
the Preference Shares, waive any past Event of Default and its consequences except an Event of Default in respect of a covenant or provision hereof which cannot be modified or amended without the consent of each Holder of Preference Shares. Upon
such waiver, any such Event of Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Guarantee, but no such waiver shall extend to any subsequent or other default or
Event of Default or impair any right consequent thereon. 


       Section 2.07. Event of Default; Notice. (a) The Guarantee Trustee shall, within 90 days after the occurrence of an Event of Default, transmit
by mail, first class postage prepaid, to the Holders of the Preference Shares, notices of all Events of Default actually known to a Responsible Officer of the Guarantee Trustee, unless such defaults have been cured before the giving of such notice,
  provided, that, the Guarantee Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or
a Responsible Officer of the Guarantee Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of the Preference Shares. 


  7


















       (b) The Guarantee Trustee shall not be deemed to have knowledge of any Event of Default unless a Responsible Officer of the Guarantee Trustee
shall have received written notice, or a Responsible Officer of the Guarantee Trustee charged with the administration of the Guarantee shall have obtained actual knowledge, of such Event of Default. 


       Section 2.08. Rights of Holders. (a) The Holders of a Majority of the Preference
Shares have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of this Guarantee or exercising any trust or power conferred upon the Guarantee Trustee under this
Guarantee. 


       (b) If the Guarantee Trustee fails to enforce its rights under the Guarantee after a Holder of Preference Shares has made a written request,
such Holder of Preference Shares may institute a legal proceeding directly against the Guarantor and Holdings to enforce the Guarantee Trustee’s rights under Article 5 or Article 7 of this Guarantee, without first instituting a legal proceeding
against the Issuer, the Guarantee Trustee or any other person or entity. Notwithstanding the foregoing, if the Guarantor and Holdings have failed to make a Guarantee Payment, a Holder of Preference Shares may directly institute a proceeding in such
Holder’s own name against the Guarantor and Holdings for enforcement of Article 5 of this Guarantee for such payment. 


       (c) For so long as any Preference Shares remain outstanding, a Holder of Preference Shares may exercise directly any right or power of a Holder
of Preference Shares under this Section 2.08. 


       (d) The guarantee herein is a guarantee of payment under the Preference Shares. As a result, in no event shall the rights to take remedial
action under this Guarantee result in any Holder of Preference Shares receiving any amount in excess of the amounts due to such Holder in accordance with the terms of the Articles and the Preference Shares, or receiving any amount due and payable to
such Holder as a Holder of Preference Shares sooner than the time at which such Holder is entitled to receive such amounts in accordance with the terms of the Indenture, the Securities, the Articles and the Preference Shares. 


       Section 2.09. Conflicting Interests. The Articles shall be deemed to be specifically described in this Guarantee for the purposes of clause
(i) of the first proviso contained in Section 310(b) of the Trust Indenture Act. 


  ARTICLE 3

  
  POWERS, DUTIES AND RIGHTS OF GUARANTEE TRUSTEE


       Section 3.01. Powers, Duties and Rights of Guarantee Trustee. (a) This Guarantee shall be held by the Guarantee Trustee for the benefit of
the Holders of the Preference Shares, and the Guarantee Trustee shall not transfer this Guarantee 


  8


















  to any Person except a Holder of Preference Shares exercising his or her rights pursuant to Section 2.08(b) or to a Successor Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee Trustee shall automatically vest in any Successor Guarantee Trustee, and such vesting and cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor Guarantee Trustee. 


       (b) If an Event of Default actually known to a Responsible Officer of the Guarantee Trustee has occurred and is continuing, the Guarantee
Trustee shall enforce this Guarantee for the benefit of the Holders of the Preference Shares. 


       (c) The Guarantee Trustee, before the occurrence of any Event of Default and after the curing or waiver of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set forth in this Guarantee, and no implied covenants shall be read into this Guarantee against the Guarantee Trustee. In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.06 and is actually known to a Responsible Officer of the Guarantee Trustee), the Guarantee Trustee shall exercise such of the rights and powers vested in it by this Guarantee, and use the same degree of
care and skill in its exercise thereof, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 


       (d) No provision of this Guarantee shall be construed to relieve the Guarantee Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that: 


        (i) Prior to the occurrence of any Event of Default and after the curing or waiving of all such Events of Default that may have occurred:
  

  
          (A) the duties and obligations of the Guarantee Trustee shall be determined solely by the express provisions of this Guarantee, and the
      Guarantee Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Guarantee, and no implied covenants or obligations shall be read into this Guarantee against the Guarantee Trustee;
      and 

          (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth of the
      statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee; but in the case of any such certificates or opinions that by
      any provision hereof are specifically required to be furnished 

  




  9


















  
    
      to the Guarantee Trustee, the Guarantee Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Guarantee (but need not confirm or investigate the accuracy of any
      mathematical calculations or other facts stated therein); 

  

        (ii) The Guarantee Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Guarantee Trustee,
  unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made; 

        (iii) The Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
  the direction of the Holders of a Majority of the Preference Shares relating to the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee, or the exercise of any trust or power conferred upon the
  Guarantee Trustee under this Guarantee; and 

        (iv) No provision of this Guarantee shall require the Guarantee Trustee to expend or risk its own funds or otherwise incur personal financial
  liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee Trustee shall have reasonable grounds for believing that the repayment of such funds or liability, or indemnity, satisfactory to
  the Guarantee Trustee, against such expense, risk or liability, is not assured to it under the terms of this Guarantee. 




       Section 3.02. Certain Rights of Guarantee Trustee. (a) Subject to the provisions of Section 3.01: 


        (i) The Guarantee Trustee may conclusively rely, and shall be fully protected in acting or refraining from acting upon, any resolution,
    certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document (whether in its original or facsimile form) believed by it to be
    genuine and to have been signed, sent or presented by the proper party or parties. 

        (ii) Any direction or act of the Guarantor or Holdings contemplated by this Guarantee shall be sufficiently evidenced by an Officers’ Certificate. 

        (iii) Whenever, in the administration of this Guarantee, the Guarantee Trustee shall deem it desirable that a matter be proved or established
    before taking, suffering or omitting any action hereunder, the Guarantee Trustee (unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and conclusively rely 




  10


















  
    upon an Officers’ Certificate which, upon receipt of such request, shall be promptly delivered by the Guarantor and/or Holdings severally. 

        (iv) The Guarantee Trustee shall have no duty to see to any recording, filing or registration of any instrument (or any rerecording, refiling
  or registration thereof). 

        (v) The Guarantee Trustee may consult with counsel of its selection, and the advice or opinion of such counsel with respect to legal matters
  shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such advice or opinion. Such counsel may be counsel to Holdings or any of its Affiliates
  and may include any of its employees. The Guarantee Trustee shall have the right at any time to seek instructions concerning the administration of this Guarantee from any court of competent jurisdiction. 

        (vi) The Guarantee Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Guarantee at the request
  or direction of any Holder, unless such Holder shall have provided to the Guarantee Trustee such security and indemnity, satisfactory to the Guarantee Trustee, against the costs, expenses (including attorneys’ fees and expenses and the expenses
  of the Guarantee Trustee’s agents, nominees or custodians) and liabilities that might be incurred by it in complying with such request or direction, including such reasonable advances as may be requested by the Guarantee Trustee; provided, however, that nothing contained in this Section 3.02(a)(vi) shall be taken to relieve the Guarantee Trustee, upon the
  occurrence of an Event of Default, of its obligation to exercise the rights and powers vested in it by this Guarantee. 

        (vii) The Guarantee Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate,
  statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Guarantee Trustee, in its discretion, may make such further inquiry or
  investigation into such facts or matters as it may see fit but shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

        (viii) The Guarantee Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through
  agents, nominees, custodians or attorneys, and the Guarantee Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder. 




  11


















        (ix) Any action taken by the Guarantee Trustee or its agents hereunder shall bind the Holders of the Preference Shares, and the signature of
    the Guarantee Trustee or its agents alone shall be sufficient and effective to perform any such action. No third party shall be required to inquire as to the authority of the Guarantee Trustee to so act or as to its compliance with any of the terms
    and provisions of this Guarantee, both of which shall be conclusively evidenced by the Guarantee Trustee or its agent taking such action. 

        (x) Whenever in the administration of this Guarantee the Guarantee Trustee shall deem it desirable to receive instructions with respect to
    enforcing any remedy or right or taking any other action hereunder, the Guarantee Trustee (i) may request written instructions from the Holders of a Majority of the Preference Shares, (ii) may refrain from enforcing such remedy or right or taking
    such other action until such written instructions are received and (iii) shall be protected in conclusively relying on or acting in accordance with such written instructions. 

        (xi) The Guarantee Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith, without negligence,
    and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Guarantee. 




       (b) No provision of this Guarantee shall be deemed to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such
act or acts or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Guarantee Trustee shall be construed to be a duty. 


       Section 3.03. Not Responsible for Recitals or Issuance of Guarantee. The recitals contained in this Guarantee shall be taken as the
statements of the Guarantor and Holdings severally, and the Guarantee Trustee does not assume any responsibility for their correctness. The Guarantee Trustee makes no representation as to the validity or sufficiency of this Guarantee.

required.

redemption payment or a liquidation payment, as applicable.

  ARTICLE 7

  
  REPRESENTATIONS AND WARRANTIES; AGREEMENTS OF THE GUARANTOR AND HOLDINGS


       Section 7.01. Representations and Warranties; Agreements of the Guarantor and Holdings. The Guarantor and Holdings each severally represents
and warrants that:  


  17


















        (a) It is duly organized and validly existing under the laws of England and Wales, with power and authority to execute and deliver, and to
    carry out and perform its obligations under, this Guarantee; and 

        (b) The execution, delivery and performance by the Guarantor and Holdings respectively of this Guarantee has been duly authorized by all
    necessary corporate action on the part of the Guarantor and Holdings respectively. This Guarantee has been duly executed and delivered by the Guarantor and Holdings respectively. 




       Section 7.02. Agreements of the Guarantor. (a) The Guarantor hereby agrees: 


        (i) that, in the event of failure of the Issuer to perform any of its obligations or to enforce when due any of the rights of the Issuer in
    respect of the exercise of any Conversion and Exchange Rights, the issue of any Preference Shares on any such exercise and the exchange of Preference Shares for Ordinary Shares or ADSs pursuant to the exercise of Conversion and Exchange Rights, in
    each case in accordance with the Articles and as referred to in the terms of the Securities and the Indenture, the Guarantor will procure the performance by the Issuer of all such obligations and the enforcement by the Issuer of all such rights;
  

        (ii) to assign to Holdings its obligations under Section 7.02(a)(ii) of the Original Guarantee, as a consequence of the succession of Holdings
    as the publicly listed company of the corporate group; and 

        (iii) that, while any Security remains Outstanding, it will not consent to, and will procure that the Issuer will not make, any amendment to
    Article 9 of the Articles which would vary, abrogate or modify the rights attaching to the Preference Shares save with (a) the consent of the Trustee or (b) (1) the written consent of the holders of not less than a majority in principal amount of
    the Outstanding Securities by the Act of said holders delivered to the Issuer, the Guarantor and the Trustee; or (2) by the adoption of a resolution, at a meeting of holders of the Outstanding Securities at which a quorum is present, by the holders
    of a majority in principal amount of the Outstanding Securities represented at such meeting, provided, however, that the consent or
    affirmative vote of the holder of each Outstanding Security adversely affected shall be required before any amendment is made to Article 9 of the Articles which is adverse to the holders of the Securities, and provided further that no consent of the Trustee nor consent or affirmative vote of any holder of Securities shall be required in relation to any
    amendment which (i) does not adversely affect the interests of any holder of Securities or (ii) is to cure any ambiguity, omission or defect or to correct or supplement any provision of Article 9 of the Articles which may be inconsistent with any
    other provision of the Articles or which is otherwise defective, or to make 




  18


















  
    any other provisions with respect to matters arising under the Articles as the Issuer, the Guarantor and the Trustee may deem necessary or desirable, in each case which does not adversely affect the interests of the holders of the
    Securities. 

        (b) The Guarantor, for so long as any Securities remain outstanding shall use its reasonable efforts to ensure that the Issuer will not be an “investment company” within the meaning of the Investment Company Act or a Passive Foreign Investment Company (“PFIC”) within the meaning of Section 1297 of the United
  States Internal Revenue Code of 1986, as amended. 

        (c) The Guarantor agrees to use all reasonable efforts to ensure that all corporate steps, including obtaining shareholder approvals if
  necessary, have been taken for the allotment and issue of the Ordinary Shares or ADSs, free of pre-emptive rights upon the exercise of Conversion and Exchange Rights. 

        (d) The Guarantor agrees to pay all stamp, stamp duty reserve or other issuance or documentary taxes or duties payable in the Cayman Islands,
  the United Kingdom or the United States in connection with (A) the issuance of Ordinary Shares upon any Conversion and Exchange and (B) their deposit with the ADR Depositary against issuance of American depositary receipts (the “ADRs”)
  evidencing American depositary shares representing the Ordinary Shares, provided, however, that the Guarantor shall not be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of
  Preference Shares, Ordinary Shares or ADSs in a name other than the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Issuer or the
  Guarantor the amount of any such tax or duty, or has established to the satisfaction of the Issuer and the Guarantor that such tax or duty has been paid. Thus Guarantor will not be obligated to pay, and each relevant Holder of Preference Shares must
  pay, all other taxes arising in connection with such exchange. 

        (e) The Guarantor agrees, as a consequence of the succession of Holdings as the publicly listed company of the corporate group, to assign to
  Holdings its obligations under Section 7.02(e) of the Original Guarantee.




       Section 7.03. Agreements of Holdings. (a) Holdings hereby agrees: 


        (i) that, in the event of failure of the Issuer to perform any of its obligations or to enforce when due any of the rights of the Issuer in
    respect of the exercise of any Conversion and Exchange Rights, the issue of any Preference Shares on any such exercise and the exchange of 




  19


















  
    Preference Shares for Ordinary Shares or ADSs pursuant to the exercise of Conversion and Exchange Rights, in each case in accordance with the Articles and as referred to in the terms of the Securities and the Indenture, Holdings
    will procure the performance by the Issuer of all such obligations and the enforcement by the Issuer of all such rights; 

        (ii) to assume, as the successor publicly listed parent company of the corporate group, the Guarantor’s obligations under Section
  7.02(a)(ii) of the Original Guarantee, and not to alter its obligation pursuant to a tripartite contract among the Issuer, the Guarantor and Holdings to issue Ordinary Shares or ADSs to holders of Preference Shares in order that the Issuer might
  meet its exchange obligations in respect of the Preference Shares in accordance with the Articles; 

        (iii) that, while any Security remains Outstanding, it will not consent to, and will procure that the Issuer will not make, any amendment to
  Article 9 of the Articles which would vary, abrogate or modify the rights attaching to the Preference Shares save with (a) the consent of the Trustee or (b) (1) the written consent of the holders of not less than a majority in principal amount of
  the Outstanding Securities by the Act of said holders delivered to the Issuer, the Guarantor, Holdings and the Trustee; or (2) by the adoption of a resolution, at a meeting of holders of the Outstanding Securities at which a quorum is present, by
  the holders of a majority in principal amount of the Outstanding Securities represented at such meeting, provided, however, that
  the consent or affirmative vote of the holder of each Outstanding Security adversely affected shall be required before any amendment is made to Article 9 of the Articles which is adverse to the holders of the Securities, and provided further that no consent of the Trustee nor consent or affirmative vote of any holder of Securities shall be required in relation to any
  amendment which (i) does not adversely affect the interests of any holder of Securities or (ii) is to cure any ambiguity, omission or defect or to correct or supplement any provision of Article 9 of the Articles which may be inconsistent with any
  other provision of the Articles or which is otherwise defective, or to make any other provisions with respect to matters arising under the Articles as the Issuer, the Guarantor and the Trustee may deem necessary or desirable, in each case which does
  not adversely affect the interests of the holders of the Securities. 

        (b) Holdings, for so long as any Securities remain outstanding, shall use its reasonable efforts to ensure that the Issuer will not be an “investment company” within the meaning of the Investment Company Act or a PFIC within the meaning of Section 1297 of the United States Internal Revenue Code of 1986, as amended. 

        (c) Holdings agrees to use all reasonable efforts to ensure that all corporate steps, including obtaining shareholder approvals if necessary,
  




  20


















  
    have been taken for the allotment and issue of the Ordinary Shares or ADSs, free of pre-emptive rights upon the exercise of Conversion and Exchange Rights. 

        (d) Holdings agrees to pay all stamp, stamp duty reserve or other issuance or documentary taxes or duties payable in the Cayman Islands, the
    United Kingdom or the United States in connection with (A) the issuance of Ordinary Shares upon any Conversion and Exchange and (B) their deposit with the ADR Depositary against issuance of ADRs evidencing American depositary shares representing the
    Ordinary Shares, provided, however, that Holdings shall not be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of Preference Shares, Ordinary Shares or ADSs in a name other than that
    of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Issuer or the Guarantor the amount of any such tax or duty, or has established
    to the satisfaction of the Issuer and the Guarantor that such tax or duty has been paid. Holdings will not be obligated to pay, and each relevant Holder of Preference Shares must pay, all other taxes arising in connection with such exchange.
  

        (e) Holdings, as the successor publicly listed parent company of the corporate group, agrees to assume the Guarantor’s obligations under
    Section 7.02(e) of the Original Guarantee, and accordingly Holdings agrees that it will, at all times while Securities are outstanding, save with either (i) the written consent of the Holders of not less than a majority in principal amount of the
    Outstanding Securities, by Act of said Holders delivered to the Issuer, the Guarantor, Holdings and the Trustee; (ii) the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of
    a majority in principal amount of the Outstanding Securities represented at such meeting; or (iii) the consent of the Trustee where, in the opinion of the Trustee, it is not materially prejudicial to the interests of the Holders of the Securities to
    give such approval: 

  
          (A) at all times keep available for issue free from pre- emptive rights out of its authorized but unissued capital such number of Ordinary
      Shares as would enable the obligation of the Issuer to procure that Preference Shares issued upon conversion of the Securities be exchanged for Ordinary Shares in accordance with the Memorandum and Articles of Association of the Issuer to be
      satisfied in full; 

          (B) not in any way modify the rights attaching to the Ordinary Shares with respect to voting, dividends or liquidation nor issue any other
      class of equity share capital carrying any rights which are more favorable than such rights except that nothing in 

  




  21


















  
    
      this clause (B) shall prevent (1) the issue of equity share capital to employees (including directors and executive officers) of Group or any of its Subsidiaries or associated undertakings pursuant to any employees’ share
        plan or option plan; (2) any consolidation or subdivision of the Ordinary Shares; (3) any modification of such rights which is not materially prejudicial to the interests of the Holders of the Securities; (4) any alteration to the Articles made in
        connection with any matters referred to in this clause (B) or supplemental or incidental thereto; (5) any issue of Ordinary Shares in connection with and upon (x) exchange of the exchangeable shares of Shire Acquisition Inc. or the remaining
        outstanding shares of Roberts Pharmaceutical Corporation or (y) the conversion of the unsecured convertible zero coupon loan note due to Arenol Corporation; or (6) any issue of equity share capital where the issue of such equity share capital
        results (or would, but for the fact that the adjustment would be less than one percent of the Exchange Ratio or that the relevant issue were at less than 95% of the current market price per Ordinary Share on the relevant Trading Day, result) in an
      adjustment to the Exchange Ratio; and 

          (C) not reduce its issued share capital, share premium account or capital redemption reserve or any uncalled liability in respect thereof
      except (1) pursuant to the terms of issue of the relevant share capital; (2) by means of a purchase or redemption; (3) as permitted by Section 130(2) of the Companies Act 1985; (4) where the reduction does not involve any distribution of assets; (5)
      where the reduction results in (or would, but for the fact that the adjustment would be less than one percent of the Exchange Ratio then in effect, result in) an adjustment to the Exchange Ratio; or (6) solely in relation to a change in the currency
      in which the nominal value of the Ordinary Shares is expressed.

  ARTICLE 9

  
  INDEMNIFICATION


       Section 9.01. Exculpation. (a) No Indemnified Person shall be liable, responsible or accountable in damages or otherwise to the
Guarantor or Holdings or any Covered Person for any loss, liability, expense, damage or claim incurred by reason of any act or omission performed or omitted by such Indemnified Person in
good faith in accordance with this Guarantee and in a manner that such Indemnified Person reasonably believed to be within the scope of the authority conferred on such Indemnified Person by this Guarantee or by law, except that an Indemnified Person
shall be liable for any such loss, liability, expense, damage or claim incurred by reason of such Indemnified Person’s negligence or wilful misconduct with respect to such acts or omissions. 


       (b) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Guarantor or Holdings and upon such
information, opinions, reports or statements presented to the Guarantor or Holdings by any Person as to matters the Indemnified Person reasonably believes are within such other Person’s professional or expert competence and who has been

against, any and all loss, liability, damage, claim or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and
expenses (including reasonable legal fees and expenses) of defending itself against, or investigating, any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligation to indemnify



  23

  ARTICLE 10

  
  MISCELLANEOUS


       Section 10.01. Successors and Assigns. All guarantees and agreements contained in this Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Guarantor and Holdings and shall inure to the benefit of the Holders of the Preference Shares then outstanding. 


       Section 10.02. Amendments. Except for those changes provided for in the two penultimate sentences of this paragraph, this Guarantee may be
modified by the Guarantor, Holdings and the Guarantee Trustee only with the prior approval of the Holders of not less than a majority in liquidation preference of the Preference Shares in issue at the relevant time (excluding any Preference Shares
beneficially owned at that time by the Guarantor and Holdings or any of their Affiliates) other than Preference Shares purchased or acquired by the Guarantor or its Affiliates in connection with transactions effected by or for the account of
customers of the Guarantor or any of its Affiliates in connection with the distribution or trading of or market making in connection with such securities and except that persons (other than Affiliates of the Guarantor) to whom the Guarantor or
Holdings or any of their subsidiaries have pledged Preference Shares may vote or convert with respect to such pledged securities pursuant to the terms of such pledge). This Guarantee may be amended without the consent of the Holders of the
Preference Shares to (i) cure any ambiguity, (ii) correct or supplement any provision in this Guarantee that may be defective or inconsistent with any other provision of this Guarantee, (iii) add to the covenants, restrictions or obligations of the
Guarantor or Holdings, (iv) conform to any change in the Investment Company Act or the rules or regulations thereunder and (v) modify, eliminate and add to any provision of this Guarantee to such extent as may be necessary or desirable;

Section 7.02, Section 7.03 nor Section 10.02 may be amended without the prior approval of each Holder of the Preference Shares. Any amendment hereof in accordance with this Section 10.02 shall be binding on all Holders. 


       Section 10.03. Judgment Currency Indemnity. (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert an amount
due from the Guarantor or Holdings under any provision of this Guarantee to a currency other than the U.S. dollar, the parties agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in
accordance with normal banking procedures, The Bank of New York could purchase such other currency with U.S. dollars at its New York office on the second Business Day preceding the day on which final judgment is given. 


  24


















       (b) The several obligations of the Guarantor and Holdings in respect of any amount due to the Guarantee Trustee or any Holders under this
Agreement shall, notwithstanding any judgment in a currency other than the U.S. dollar, be discharged only to the extent that on the Business Day following receipt by the Guarantee Trustee or such Holders, as the case may be, of any amount adjudged
to be so due in such other currency, the Guarantee Trustee or such Holders, as the case may be, may in accordance with normal banking procedures purchase U.S. dollars with such other currency. 


       (c) If the amount of U.S. dollars so purchased is less than the amount originally due to the Guarantee Trustee or such Holders, as the case may
be, in U.S. dollars, the Guarantor and Holdings agree severally, to the fullest extent that they may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Guarantee Trustee or such Holders, as the case
may be, against such loss. 


       (d) If the amount of U.S. dollars so purchased exceeds the amount originally due to the Guarantee Trustee or such Holders, as the case may be,

       Section 10.04. Assignment of the Guarantor and Holdings. The Guarantor and Holdings will not assign their respective obligations under the
Guarantee, except in the case of a merger, consolidation or a sale or contribution of substantially all of its assets, where the Guarantor or Holdings is not the surviving entity.

       Section 10.06. Governing Law. THIS GUARANTEE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF, EXCEPT FOR SECTION 6.01 HEREOF, WHICH SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF ENGLAND AND WALES, WITHOUT REGARD TO CONFLICTS OF LAWS
PRINCIPLES THEREOF. THE PARTIES HERETO EACH HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY TRANSACTION RELATED HERETO.

       (b) Each of the Guarantor and Holdings irrevocably consents to the jurisdiction of any court of the State of New York or any United States
federal court sitting in the Borough of Manhattan, New York City, New York, United States, and any appellate court from any thereof, and waives any immunity from the jurisdiction of such courts over any suit, action or proceeding that may be brought
in connection with this Guarantee. Each of the Guarantor and Holdings irrevocably waives, to the fullest extent permitted by law, any objection to any suit, action, or proceeding that may be brought in connection with this Guarantee in such courts
whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an 


  26


















  inconvenient forum. Each of the Guarantor and Holdings agrees that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Guarantor or Holdings and may be enforced in
any court to the jurisdiction of which such Guarantor or Holdings is subject by a suit upon such judgment; provided that service of process is effected upon the Guarantor or Holdings in the
manner provided herein. Notwithstanding the foregoing, any suit, action or proceeding brought in connection with this Guarantee may be instituted in any competent court in England and Wales. 


       (c) Each of the Guarantor and Holdings agrees that service of all writs, process and summonses in any suit, action or proceeding brought in
connection with this Guarantee against the Guarantor or Holdings, as the case may be, in any court of the State of New York or any United States federal court sitting in the Borough of Manhattan, New York City may be made upon CT Corporation System
at 111 8th Avenue, 13th Floor, New York, New York 10011, whom each of the Guarantor and Holdings irrevocably appoints as its authorized agent for service of process. Each Guarantor represents and warrants that CT Corporation System has agreed to act
as the agent for service of process for the Guarantor and Holdings as the case may be. Each Guarantor and Holdings agrees that such appointment shall be irrevocable so long as any of the Securities or Preference Shares remain outstanding or until
the irrevocable appointment by the Guarantor or Holdings, as the case may be, of a successor in The City of New York as its authorized agent for such purpose and the acceptance of such appointment by such successor. Each of the Guarantor and
Holdings further 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 as aforesaid. If CT Corporation System shall cease to act
as the agent for service of process for the Guarantor or Holdings, the Guarantor or Holdings shall appoint without delay another such agent and provide prompt written notice to the Guarantee Trustee of such appointment. With respect to any such
action in any court of the State of New York or any United States federal court in the Borough of Manhattan, New York City, service of process upon CT Corporation System, as the authorized agent of the Guarantor or Holdings, as the case may be, for
service of process, and written notice of such service to the Guarantor or Holdings, as the case may be, shall be deemed, in every respect, effective service of process upon the Guarantor or Holdings, as the case may be. 


       (d) Nothing in this Section shall affect the right of any party to serve legal process in any other manner permitted by law.
