Such conditions must be objective and specified at the Date of Grant and must not be waived or changed by the Grantor unless where events happen which cause the Grantor reasonably to consider that: 2.2.1 a changed Exercise Condition would be a fairer measure of performance, and would not be materially more or less difficult to satisfy than the condition as it existed or when first imposed; and 2.2.2 the changed Exercise Condition is similar in nature. 2.3 The grant of an Option or the delivery of any Shares following its exercise shall be subject to obtaining any approval or consent required under any applicable laws, regulations of governmental authority and the requirements of the United Kingdom Listing Authority, and any other securities exchange on which the Shares are traded. 2.4 No Option may be granted, exercised, released or surrendered at a time when such grant, exercise, release or surrender would not be in accordance with the "Model Code on Directors' Dealings in Securities" issued by the United Kingdom Listing Authority, as amended from time to time, or any other code adopted by the Company. 2.5 The Grantor shall execute a deed as evidence of the grant of an Option, which deed may be in respect of an individual Option or any number of Options granted at the same time. As soon as practicable after the Date of Grant, the Grantor shall issue to each Participant a certificate in respect of the Option in such form as the Grantor may from time to time prescribe. 2.6 Participants are not required to pay for the grant of an Option. 2.7 Neither an Option nor any rights in respect of it may be transferred, assigned or otherwise disposed of by a Participant to any other person without the Grantor's prior consent, except 4 that, on the death of a Participant, his Option may be transmitted to his personal representatives. 2.8 A Participant may surrender all or part of his Option by notice in writing to the Secretary of the Company within 30 days of the Date of Grant. If this happens, the Option will, to the extent surrendered, be deemed for all purposes never to have been granted, and no further Options shall be granted to the Participant within 60 days of the date of surrender. No consideration is payable for the surrender. 2.9 If the Grantor purports to grant an Option which is inconsistent with the limits in Rule 3 or 4, the Option will be limited and will take effect from the Date of Grant on a basis consistent with the Rules, and the Grantor may call in the option certificate for endorsement, replacement or cancellation. 2.10 The Grantor may grant an Option to acquire cash or other assets (including Shares) which: 2.10.1 on exercise, subject to satisfying any Exercise Condition where required by the Rules, delivers a value to the Participant related to the increase in the Market Value of a Share from the Date of Grant to the date of effective exercise; and 2.10.2 is otherwise subject to the Rules, which shall be interpreted in such manner as the Grantor reasonably determines is necessary to give effect to this Rule 2.10. 2.11 All Options granted to Participants in the U.S. shall be evidenced by an instrument(s) in such form or forms as may from time to time be approved by the Company which, shall set out the manner in which a Participant may exercise his Option and the form of payment for the Shares or ADSs issuable or transferable under it. 2.12 The Company may arrange for any Option to constitute a right to ADSs rather than Shares, in which case the references to "Shares" in the Plan shall be deemed to be references to "ADSs" as the context may require. 2.13 In its discretion and upon such terms and conditions as it may implement from time to time, the Company may arrange for (i) any Option over Shares to be satisfied in the form of ADSs, and for any Option over ADSs to be satisfied in the form of Shares and (ii) for the exercise price of any Option expressed in Sterling to be paid in U.S. dollars, and for the exercise price of any Option expressed in U.S. dollars to be paid in Sterling using such rate of exchange as the Grantor may reasonably specify. 3 INDIVIDUAL LIMITS 3.1 Subject to Rule 3.2 no Option shall be granted to an Eligible Employee which would, at the Date of Grant, result in the market value (measured at the relevant Date of Grant) of the Shares over which he has been granted Options under the Plan and options under any other Market Value Option Plan in respect of any financial year of the Company exceeding 200% of his annual rate of basic salary. 3.2 In calculating the limit in Rule 3.1, no account shall be taken of any Shares which have been put under Option to ensure that a Participant who agrees to satisfy any liability to employer's national insurance contributions (or the overseas equivalent to the extent this is lawful) is not financially disadvantaged. 4 PLAN LIMITS 4.1 In any ten year period, the number of Shares which may be allocated under the Plan and under any other Employees' Share Scheme adopted by the Company shall not exceed such number 5 as represents ten per cent of the issued ordinary share capital of the Company from time to time. 4.2 In any twelve month period, the number of Shares allocated under the Plan and under any other Discretionary Share Plan adopted by the Company shall not exceed such number as represents 0.5 per cent of the issued ordinary share capital of the Company from time to time unless the number of Shares to be allocated under the Plan and under any other Discretionary Share Plan adopted by the Company, when aggregated with the number of Shares in any ten year period already allocated under the Plan and under any other Discretionary Share Plan adopted by the Company, represents less than five per cent of the issued ordinary share capital of the Company from time to time, 4.3 In determining the above limits: 4.3.1 any Shares allocated to the Trustees under the Plan or any other Employees' Share Scheme adopted by the Company shall be included; and 4.3.2 no account shall be taken of any Shares where the right to acquire such Shares was released or lapsed without being exercised, including pursuant to Rule 2.8 above. 4.4 In this Rule "allocate" shall mean, in the case of any share option plan, the placing of unissued shares under option and, in relation to other types of Employees' Share Schemes, the commitment to issue shares or the issue and allotment of shares (whichever is the earlier). 5 EXERCISE AND LAPSE OF OPTIONS - GENERAL RULES 5.1 An Option can only be exercised 5.1.1 except where exercise is allowed as described in Rules 6 or 7, on or after the third anniversary of the Date of Grant or such other date determined by the Grantor at the Date of Grant; 5.1.2 except where exercise is allowed as described in Rule 6 or 7, by a Participant while he is an officer or employee of a Group Member; 5.1.3 except where otherwise provided in Rule 6 and 7, if the Exercise Condition (if any) is satisfied or waived. 5.2 An Option shall lapse on the earliest of: 5.2.1 the tenth anniversary of the Date of Grant (or such other period as determined by the Grantor at the Date of Grant); 5.2.2 the expiry of all applicable periods specified in Rule 6; 5.2.3 the expiry of any of the applicable periods specified in Rule 7 except to the extent an Option is released in consideration of the grant of a New Option (during one of the periods specified in Rule 7) pursuant to Rule 8.2; 5.2.4 where Rule 8.1 applies, the expiry of the Appropriate Period except where an Option is released in consideration of a New Option pursuant to Rule 8.2; 5.2.5 the Participant ceasing to hold an office or employment or giving or being given notice to terminate employment with a Group Member in any circumstances except where it arises: 5.2.5.1 on any of the grounds specified in Rule 6; or 6 5.2.5.2 during any of the periods specified in Rule 7 other than for an act or omission of the Participant entitling his employer to terminate without notice his office or employment or where the Participant gives notice to terminate; 5.2.6 subject to Rule 7.5, the passing of an effective resolution or the making of an order by the Court for the winding up of the Company; 5.2.7 the Participant being deprived of the legal or beneficial ownership of the Option by operation of law or being declared bankrupt, unless the Grantor determines otherwise; and 5.2.8 the Participant purporting to transfer or dispose of the Option or any rights in respect of it other than as permitted under Rule 2.7. 5.3 For the purposes of this Rule 5 and Rule 6 below, a Participant shall not be treated as ceasing to hold office or employment with a Group Member until he has ceased to hold office or employment with all Group Members. 5.4 For the purposes of the Plan, a woman on maternity leave will not cease to hold an office or employment until the earlier of the date on which she notifies her employer of her intention not to return or the date on which she ceases to have statutory or contractual rights to return to work. 6 EXERCISE OF OPTIONS - EXCEPTIONS TO THE GENERAL RULES WHEN LEAVING/CHANGING EMPLOYMENT 6.1 If a Participant dies, even if any Exercise Condition has not been satisfied, a proportion of his Option can be exercised for a period of twelve months from the date of death (which proportion will reflect the number of whole months of the Option Period which have elapsed at the date of death) unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise within 30 days from the date of death. The proportion of the Option that can be exercised shall be calculated as soon as practicable and notified to the Participant's personal representatives. 6.2 If a Participant retires from a Group Member, he may, subject to satisfying any Exercise Condition, exercise a proportion of his Option within six months of the expiry of the Option Period (which proportion will reflect the number of months of the Option Period which have elapsed at the date of retirement) unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise. 6.3 If a Participant ceases to hold office or employment with a Group Member by reason of injury, ill-health or disability (evidenced to the satisfaction of the Board), he may exercise a proportion of his Option within twelve months of the date of cessation, even if any Exercise Condition has not been satisfied (which proportion will reflect the number of whole months of the Option Period which have elapsed at the date of cessation) unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise within 30 days of the date of cessation. 6.4 If a Participant ceases to hold office or employment with a Group Member by reason either of job elimination or a reduction in workforce directly affecting him (as determined in the opinion of the Board), he may exercise a proportion of his Option within three months of the date of cessation, even if any Exercise Condition has not been satisfied (which proportion will reflect the number of whole months of the Option Period which have elapsed at the date of cessation) unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise within 30 days of the date of cessation. 7 6.5 If a Participant ceases to hold office or employment with a Group Member by reason of the company in the Group which employees him ceasing to be a Group Member or because of the transfer or sale of the undertaking (or part of the undertaking) in which he is employed to a person who is not a Group Member, he may exercise a proportion of his Option within three months of the date of cessation, even if any Exercise Condition has not been satisfied (which proportion will reflect the number of whole months of the Option Period which have elapsed at the date of cessation) unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise within 30 days from the date of cessation. 6.6 If a Participant ceases to hold office or employment with a Group Member for any reason other than those specified in Rules 6.1, 6.2, 6.3, 6.4 and 6.4, his Option shall lapse unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise within three months from the date of cessation. 7 EXERCISE OF OPTIONS - EXCEPTIONS TO THE GENERAL RULES ON TAKEOVER, RECONSTRUCTION AND WINDING-UP 7.1 Subject to Rules 7.3, 7.6 and 8.1 below, if any person obtains Control of the Company as a result of making, either: 7.1.1 a general offer to acquire the whole of the issued ordinary share capital of the Company (which is either unconditional or made on a condition such that if it is satisfied the person making the offer will have Control of the Company); or 7.1.2 a general offer to acquire all the shares in the Company which are of the same class as the Shares, (in either case disregarding any shares already owned by it or by any company associated with it), Options may be exercised within six months of the time when the person making the offer has obtained Control of the Company and any condition subject to which the offer is made has been satisfied.) 7.2 For the purpose of Rule 7.1 a person shall be deemed to have obtained Control of the Company if he and others acting in concert (as defined by the City Code on Take-overs and Mergers) with him have together obtained Control of it. 7.3 Subject to Rules 7.6 and 8.1, if any person becomes bound or entitled to acquire Shares under sections 428 to 430F of the Companies Act 1985, Options may be exercised at any time within the period of four weeks beginning on the date on which that person first becomes so bound or entitled; 7.4 If under section 425 of the Companies Act 1985 it is proposed that the Court sanctions a compromise or arrangement for the purposes of or in connection with the reconstruction of the Company or its amalgamation with any other company or companies the following shall apply: 7.4.1 the Company shall notify all Participants at the same time as it sends notices to members of the Company calling the meeting to consider such a compromise or arrangement; 7.4.2 subject to Rules 7.6 and 8.1, Options may then be exercised conditional on such compromise or arrangement being sanctioned by the Court and becoming effective before the earlier of the expiry of six months from the date of such notice and the date on which the compromise or arrangement becomes effective; 8 7.4.3 to the extent unexercised, Options shall lapse conditionally on the compromise or arrangement being sanctioned by the Court and becoming effective; and 7.4.4. after exercising an Option the Participant shall transfer or otherwise deal with the Shares issued to him so as to place him in the same position (so far as possible) as would have been the case if such Shares had been subject to such compromise or arrangement. 7.5 If notice is duly given of a resolution for the voluntary winding-up of the Company, the Company shall notify all Participants. Subject to Rule 7.6, Options may then be exercised until the resolution is duly passed or defeated or the meeting concluded or adjourned sine die provided that the exercise of an Option pursuant to this Rule shall be conditional upon the resolution being duly passed. If the resolution is duly passed all Options shall, to the extent that they have not been exercised, lapse immediately. 7.6 Where Rules 7.1, 7.3, 7.4 or 7.5 apply only a proportion of an Option can be exercised (which proportion will reflect the number of months of the Option Period which have elapsed at the date of the relevant event) and the Option may only be exercised having regard to the extent to which any Exercise Condition has been satisfied at the date of the relevant event unless and to the extent the Grantor, acting fairly and reasonably, determines otherwise. 8 EXCHANGE OF OPTIONS FOLLOWING TAKEOVER ETC. 8.1 Rules 7.1, 7.3 and 7.4 shall not apply where: 8.1.1 the events are part of a scheme or arrangement whereby another company ("the Acquiror") obtains Control of the Company; 8.1.2 immediately after the Acquiror obtains Control, the issued ordinary share capital of the Acquiror is owned substantially by the same persons who were equity shareholders of the Company immediately prior to the Acquiror obtaining Control; and 8.1.3 the Acquiror agrees to grant New Options in accordance with Rule 8.2 in consideration for the release of any Options which have not lapsed. 8.2 If: 8.2.1 Options become exercisable under Rules 7.1, 7.3 or 7.4 and a company obtains Control of the Company; or 8.2.2 a company obtains Control in circumstances where Rule 8.1 applies; or 8.2.3 a company obtains Control of any Group Member as a result of a demerger; any Participant may during the Appropriate Period, by agreement with the acquiring company, release any Option which has not lapsed ("the Old Option") in consideration of the grant to him of an option ("the New Option") which relates to shares in a different company (whether the company which has obtained Control of the Company itself or some other company). In the case of a demerger, a New Option may be granted in respect of an appropriate part of an Old Option. 8.3 Where Rule 8.2 applies, the provisions of the Plan shall for this purpose be construed as if: 8.3.1 the New Option were an option granted under the Plan at the same time as the Old Option; 9 8.3.2 except for the purpose of the definition of "Participating Company" in Rule 1.1 and the reference to "the Company" in Rule 13.2, the reference to The BOC Group plc in the definition of "the Company" in Rule 1.1 were a reference to the different company mentioned in Rule 8.2; 8.3.3 subject to Rule 8.3.4 any Exercise Condition will not apply; and 8.3.4 where Rule 8.1 applies, the Exercise Condition will apply either in its original form or an appropriately amended form unless the Grantor of the New Option determines that it should be disapplied in whole or in part. 9 MANNER OF EXERCISE 9.1 Subject to Rule 2.3, an Option may be exercised in whole or in part. 9.2 Subject to Rules 9.4 and 10.6 below, an Option may be exercised by delivering to the Company Secretary or such other person as the Grantor determines (as agent for the Grantor): 9.2.1 an option certificate covering at least all the Shares over which the Option is then to be exercised; 9.2.2 a notice of exercise in the prescribed form duly completed and signed by the Participant (or by his duly authorised agent); and 9.2.3 a remittance for the aggregate Option Price made payable to the Company (as agent for the Grantor, where appropriate) in respect of the Shares over which the Option is exercised provided that the Grantor may from time to time prescribe a different exercise procedure. 9.3 If an Exercise Condition must be satisfied before an Option may be exercised, the delivery of the notice of exercise shall not be treated as effecting the exercise of the Option unless and until the Exercise Condition has been satisfied. The effective date of exercise shall be the later of the date of delivery of the notice of exercise and the date that the Exercise Condition has been satisfied and consequently Rule 12.2 shall not apply. 9.4 The Grantor may require a Participant to discharge or assume any liability to taxation or social security contributions which may arise on the exercise of an Option. The Company, any Participating Company, any Group Member, any employing company or the Trustees may withhold any amount and make any such arrangements as it considers appropriate to meet any liability to taxation or social security contributions in respect of Options (including their grant and exercise). These arrangements may include the sale of any Shares on behalf of a Participant or the reduction of the number of Shares receivable by the Participant. 10 ISSUE OR TRANSFER OF SHARES 10.1 The Company shall procure that sufficient Shares are available to transfer or allot to satisfy the exercise of all outstanding Options. 10.2 Subject to Rules 2.3 and 2.4, Shares shall be issued or transferred to the Participant (or his nominee) within 28 days following the date of effective exercise of the Option. 10.3 Shares issued or transferred pursuant to the Plan will rank pari passu in all respects with the Shares then in issue, except that they shall not rank for any right attaching to Shares by reference to a record date preceding the effective date of exercise. 10 10.4 If the Shares are listed on a recognised stock exchange, the Company shall apply for listing of any Shares issued pursuant to the Plan (and not already listed) as soon as practicable after their allotment. 10.5 Any Shares acquired on the exercise of Options will be subject to the articles of association of the Company from time to time. 10.6 The Grantor may determine at any time that a Participant who exercises his Option shall not pay the Option Price, but shall instead receive an amount (in Shares, other assets or cash) equal to the amount by which the Market Value of the Shares on the date of exercise in respect of the Option is exercised exceeds the Option Price. 11 ADJUSTMENTS 11.1 The number of Shares over which an Option is granted, and the Option Price (and where an Option has been exercised but no Shares have been allotted or transferred pursuant to such exercise, the number of Shares which may be so allotted or transferred and the price at which they may be acquired) shall be adjusted in such manner as the Grantor shall determine following any capitalisation issue, any offer or invitation made by way of rights, subdivision, consolidation, reduction or other variation in the share capital of the Company which in the reasonable opinion of the Grantor justifies such an adjustment, so that (as nearly as may be without involving fractions of a Share) the aggregate Option Price payable in respect of an Option (if it was exercised in full) is unchanged. 11.2 Apart from pursuant to this Rule 11.2, no adjustment under Rule 11.1 above shall reduce the Option Price to less than the nominal value of a Share. Where an Option subsists over both issued and unissued Shares any such adjustment may only be made if the reduction of the Option Price of Options over both issued and unissued Shares can be made to the same extent. Any adjustment made to the Option Price of Options over unissued Shares shall only be made if and to the extent that the Board is authorised to capitalise from the reserves of the Company a sum equal to the amount by which the nominal value of the Shares in respect of which the Option is exercisable exceeds the adjusted aggregate Option Price and to apply such sum in paying up such amount on such Shares so that on exercise of any Option in respect of which such a reduction shall have been made the Board shall capitalise such sum (if any) and apply the same in paying up such amount as aforesaid. 11.3 The Grantor may take such steps as it may consider necessary to notify Participants of any adjustment made under this Rule 11 and to call in, cancel, endorse, issue or reissue any certificate as a result of such adjustment. 12 ADMINISTRATION 12.1 The Board shall administer the Plan. The Board shall have full authority, consistent with the Plan to interpret and construe any provision of the Plan and to adopt such regulations for administering the Plan as it may deem necessary or appropriate. The Board's decision shall be final and binding on all parties. 12.2 Any notice or other communication under or in connection with the Plan may be given by personal delivery or by sending the same by electronic means or by post, in the case of a company to its registered office, and in the case of an individual to his last known address, or, where he is an officer or employee of a Group Member, either to his last known address or to the address of the place of business at which he performs the whole or substantially the whole of the duties of his office or employment, and where a notice or other communication is given by post, it shall be deemed to have been received 72 hours after it was put into the post properly addressed and stamped and if by electronic means when the sender receives electronic confirmation of delivery or if not available 24 hours after sending the notice. 11 12.3 The Company may send to Participants copies of any notice or document normally sent by the Company to the holders of Shares. 12.4 In the case of partial exercise of an Option, the Grantor may in consequence call in, endorse, cancel and reissue, as it considers appropriate, any certificate for the balance of the Shares over which the Option was granted. 12.5 If any certificate is worn out, defaced or lost, it may be replaced on such evidence being provided as the Grantor may require. 12.6 The Participating Companies shall bear the costs of introducing and administering the Plan in such proportions as may be determined by the Company. 12.7 The Company and any Subsidiary of the Company may provide money to the Trustees or any other person to enable them or him to acquire Shares to be held for the purposes of the Plan, or enter into any guarantee or indemnity for those purposes, to the extent permitted by section 153 of the Companies Act 1985. In addition, the Company may require any Subsidiary of the Company to enter into such other agreement or agreements to require such Subsidiary of the Company to reimburse the Company for any other amounts paid by the Company under the Plan, directly or indirectly in respect of such Subsidiary's employees. 13 CHANGING THE PLAN 13.1 Subject to the rest of this Rule 13, the Board may at any time alter or add to all or any of the provisions of the Plan in any respect, (but only with the prior consent of the Trustees if there are subsisting Options which they have granted or agreed to satisfy which will be affected by the alteration or addition). 13.2 No alteration or addition to the material advantage of Participants or employees shall be made under Rule 13.1 without the prior approval by ordinary resolution of the members of the Company in general meeting, where such alteration or addition relates to: 13.2.1 the definition of "Eligible Employee";

DEFINITIONS 1.1 The words and expressions used in this Schedule 2 (the `US Schedule') which have capital letters have the meanings set out below, and words and expressions not otherwise defined have the same meaning they have in the Rules of the Plan to which this Schedule 2 is attached: Code The United States Internal Revenue Code of 1986 (as amended); Eligible Employee (A) For the purposes of an ISO, any person who at the Date of Grant is an employee or director in his capacity as an employee of either the Company or a Parent or Subsidiary of the Company and who is required to devote substantially the whole of his working time to the business of the Company and its Subsidiaries; (B) For the purposes of an Option which is not an ISO, the meaning given in the Plan; ISO An incentive stock option within the meaning of section 422 of the Code; Option Price (A) The meaning given in the Plan; and (B) In the case of an ISO where the Eligible Employee owns (within the meaning of Section 422 (b) (6) of the Code) Shares equal to more than 10% of the total combined voting power of all classes of shares of the Company, or of its Parent of Subsidiary (a `Ten Percent Shareholder'), not less than 110% of the Market Value of a Share on the Date of Grant; Parent Any company which is a parent corporation of the Company within the meaning of section 424(e) of the Code; Securities Act the United States Securities Act of 1933 (as amended); Subsidiary (A) The meaning given by section 736 of the Companies Act 1985; and (B) A subsidiary corporation within the meaning of section 424(f) of the Code; US Person the meaning given by Rule 902(k) promulgated under the Securities Act; US Person the meaning given by Rule 902(k) promulgated under the Securities Act; 18 2. GENERAL 2.1 The purpose of this Schedule 2 is to benefit Eligible Employees who are employed or remunerated in the United States or who are citizens of the United States. 2.2 Options granted to Eligible Employees may be either ISOs or Options which are not ISOs ("non-qualified stock options"). 2.3 This Schedule 2 is contingent upon shareholder approval within twelve months before or after adoption of this Schedule 2 by the Board. Failure to receive such approval shall render Options granted under this Schedule 2 null and void. 2.4 The grant and exercise of any Option shall be subject to fulfilling the requirements (including obtaining any required approval or consent) of the provisions of the Securities Act or of any applicable regulation or enactment. Neither the Options nor the Shares may be resold or otherwise transferred within the United States of America, its territories or possessions, any State of the United States of America or the District of Columbia or to any U.S. Person, unless they are registered under the Securities Act and qualified under all state securities laws or an exemption from such registration and qualification is available. 2.5 Shares shall not be issued to a US Person pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act, the United States Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder and all applicable state securities laws, and shall be further subject to the approval of Counsel for the Company with respect to such compliance. 2.6 Any adjustment pursuant to Rule 11 of the Plan shall, in the case of ISOs, be made in a manner consistent with Section 422 of the Code. 2.7 The Company shall (i) administer the US Schedule, (ii) establish from time to time such rules and regulations as it may deem appropriate for the proper administration of the US Schedule, and (iii) make such determinations under, and such interpretations of, and take such actions in connection with, the US Schedule as it may deem necessary or advisable, including (but not by way of limitation) determinations, interpretations and actions to ensure that Options that are intended to qualify as ISOs shall so qualify. 2.8 An ISO may not be exerciseable more than 10 years after the Date of Grant (5 years in the case of an ISO granted to a Ten Percent Shareholder). 2.9 The US Schedule may be further modified to ensure that any Option that is intended to be an ISO under the US Schedule will comply with the requirements of Section 422 of the Code. 2.10 It shall be a condition to the obligation of the Company to deliver Shares or ADSs pursuant to any Option under the US Schedule that the Participant pays to the Company (or the Subsidiary that employs the Participant) such amount as may be required by the Company or such Subsidiary for the purpose of satisfying any liability for any US Federal, state or local taxes of any kind required to be withheld with respect thereto. Any Option granted under the US Schedule may require the Company (or the Subsidiary that employs the recipient), or permit the recipient of the Option to elect, in accordance with any applicable rules established by the Company, to withhold or to pay all or a part of the amount of the withholding taxes in Shares or ADSs. Such election may be denied by the Company in its sole discretion, or may be made subject to certain conditions specified by the Company. 19 The applicable ISO award shall provide that if a Participant makes a disposition, within the meaning of Section 424(c) of the Code and the regulations promulgated thereunder, of any Shares or ADSs issued to such Participant pursuant to the exercise of an ISO award within the two-year period commencing on the Date of Grant or within the one-year period commencing on the date of transfer of such Shares or ADSs to the Participant pursuant to such exercise, the Participant shall, within 10 days of such disposition, notify the Company of it (or the Subsidiary that employs the Participant), by delivery of written notice to the Company or such Subsidiary at its principal executive office. 3. AMENDMENTS TO THE PLAN For the purposes of Options granted under this Schedule 2, the Rules of the Plan shall apply subject to the following amendments: 3.1 In respect of ISOs only, Rule 2.7 of the Plan shall be amended to read as follows: "Every Option shall be personal to the Participant to whom it is granted and shall not be transferable otherwise than by will or the laws of descent and distribution, and is exercisable, during his lifetime, only by him." 3.2 Rule 5.1.2 of the Plan shall be amended to read as follows: "except where exercise is allowed as described in Rule 6 or 7, by a Participant while he is an employee, or officer in his capacity as an employee, of a Group Member." 3.3 In Rule 6.3 of the Plan, the words "injury, ill-health or disability (evidenced to the satisfaction of the Board)" shall be replaced by the following: "permanent and total disablement, meaning that the Participant is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than twelve months". 3.4 In Rules 6.2 and 7.1 and 7.4.2, the reference to "six months" shall be replaced by "three months". 4. LIMITS 4.1 Shares placed under Options granted under this Schedule 2 shall be taken into account for the purpose of Rule 4 of the Plan and vice versa. 4.2 The aggregate Market Value (determined at the Date of Grant) of Shares with respect to which ISOs granted under this Schedule 2 and under all incentive stock option plans of the Company and its Parent and Subsidiaries shall first become exercisable by any Participant in any calendar year shall not exceed 100,000 United States Dollars or the Sterling equivalent, and, in the event that such limit is exceeded such ISOs shall be treated, to the extent of such excess, as nonqualified stock options. To the extent that such Participant holds two or more ISOs which would become exercisable for the first time in the same calendar year, the foregoing limitation on the exercisability of such Options as Incentive Stock Options shall be applied on the basis of the order in which such Options are granted. 4.3 The maximum aggregate number of Shares which may be issued under the Plan with respect to ISOs (the "ISO Maximum") is 49,000,000. Shares subject to outstanding Options shall, to the maximum permitted by Section 422 of the Code, be available for subsequent issuance under this Schedule 2 and the ISO Maximum to the extent the Options expire, terminate, or are cancelled for any reason prior to exercise in full. Should any changes be made to the Shares by reason of any sub-division, stock dividend, recapitalisation, consolidation of Shares, exchange of Shares, or other change affecting the Shares without the receipt of consideration, appropriate adjustment shall be made, in a manner consistent within Section 20 422 of the Code, to the maximum number of Shares subject to the Plan and the ISO Maximum and to the Option Price under each outstanding Option in order to prevent dilution or enlargement of benefits thereunder. Adjustments determined by the Grantor, or their properly authorised designee, shall be binding and conclusive. 21
