Rules of the BP Plan 2011

1 Grant of Options

1.1 Grant of Options

1.1.1 The Designated Corporate Officer may resolve to grant to any Eligible Employee an Option to acquire such number of Shares as the Designated Corporate Officer may determine.

1.1.2 Unless the Designated Corporate Officer decides otherwise in any particular case, Options must not be granted to an Eligible Employee who has given or received notice of termination of employment with a Member of the Group, whether or not such termination is lawful.

1.2 Time when Options may be granted

Options may be granted at any time, subject to the application of Dealing Restrictions.

1.3 Conditions

When granting an Option, the Designated Corporate Officer may make its exercise conditional on the satisfaction of any condition(s). Conditions may be different for different Optionholders. If conditions apply, an Optionholder will be notified of the conditions in such manner as the Designated Corporate Officer decides. Any condition must be specified at the Date of Grant and may provide that an Option will lapse if it is not satisfied. The Designated Corporate Officer may waive or change a condition in any way he sees fit.

1.4 Notification of grant of Options

The Designated Corporate Officer will notify the grant of Options to Optionholders in such manner as he determines.

1.5 No payment

Optionholders are not required to pay for the grant of any Option.

1.6 Disclaimer of Option

Any Optionholder may disclaim all or part of his Option within 80 days after the Date of Grant by notice in writing to the Company. If this happens, the Option will be deemed never to have been granted under the Plan. Optionholders are not required to pay for the disclaimer.

1.7 Restriction on disposal of interests and hedging

1.7.1 Subject to rule 1.7.2, an Optionholder may not sell, transfer, assign, hedge, charge or otherwise dispose of an Option (or part of or any interest in an Option) and must not enter into any transaction which transfers the risk of price movements with regard to the Shares subject to an Option. If he does, whether voluntarily or involuntarily, then the Designated Corporate Officer may determine that the whole of the Option lapses.

1.7.2 Rule 1.7.1 does not apply:

(i) to the transmission of an Option on the death of an Optionholder to his personal representatives; or

1

(ii) to the assignment of an Option, with the prior consent of the Designated Corporate Officer, subject to any terms and conditions the Designated Corporate Officer imposes.

1.8 Issue of Shares

Shares may not be issued or transferred from treasury to satisfy Options without prior approval of this Plan by shareholders of the Company.

1.9 Options over ADSs

The Designated Corporate Officer may decide to grant options in the form of an Option to acquire ADSs and references in these rules Share, Option, Price etc. shall be construed accordingly. Upon the exercise of any Option to acquire ADSs the Company will make arrangements for the Optionholder to acquire ADSs.

2 Option Price

2.1 Setting the Option Price

The Option Price will be not less than the Market Value of a Share on the Date of Grant.

2.2 Market Value

“Market Value” on any particular day means:

(i) the closing middle market quotation of a Share (taken from the Daily Official List of the London Stock Exchange) on the immediately preceding Business Day or, in the case of an ADS listed on the New York Stock Exchange, the closing price quoted on the New York Stock Exchange for that preceding Business Day; or

(ii) if the Designated Corporate Officer so decides, the average of the closing middle market quotations of a Share (taken from the Daily Official List of the London Stock Exchange) or, in the case of an ADS listed on the New York Stock Exchange, the closing price quoted on the New York Stock Exchange, over the immediately preceding three or five Business Days;

3 Adjustment of Options

If there is:

(i) a variation in the equity share capital of the Company, including a capitalisation or rights issue, sub-division, consolidation or reduction of share capital;

(ii) a demerger (in whatever form) or exempt distribution by virtue of Section 1075 of the Corporation Taxes Act 2010;

the Designated Corporate Officer may adjust the number of Shares comprised in each Option and the Option Price in any way (including retrospective adjustments) which the Designated Corporate Officer considers appropriate.

3.2 Nominal value

The Option Price may not be adjusted to a price less than the nominal value of a Share.

3.3 Notice

The Designated Corporate Officer may notify Optionholders of any adjustment made under this rule 3.

4 Exercise and lapse – general rules

4.1 Exercise

An Optionholder may exercise his Option at any time during the Option Period (subject to any Dealing Restriction) following Vesting and subject to any conditions being satisfied in accordance with rule 1.3.

4.2 Lapse

An Option will lapse at the end of the Option Period or, if earlier, on the earliest of:

4.2.1 the date the Optionholder ceases to be an employee;

4.2.2 the end of the last day on which the Option can be exercised in any circumstance referred to in rules 5.1, 5.2, 5.3 or 6; or

4.2.3 the date when any circumstance referred to in rule 1.7, occurs.

4.3 Priority

If an Option becomes exercisable under more than one provision of the rules of the Plan, the provision which results in the shortest Exercise Period of the Option will prevail.

4.4 Forfeiture

4.4.1 Notwithstanding any other rules of the Plan (including, without limitation, rules 5.1, 5.2 or 5.3), if the Designated Corporate Officer determines that an Optionholder has engaged in personal conduct (including, but not limited to, a violation of the BP Code of Conduct) which the Designated Corporate Officer considers was contrary to the legitimate expectations of the Company for an employee in the Optionholder’s position then the Designated Corporate Officer may reduce the number of Shares subject to an Option (including to zero) or if an Option has already been exercised but Shares have not yet been transferred (because of, for example, any Dealing Restrictions), transfer to the Optionholder a reduced number of Shares or no Shares at all.

4.4.2 Where an Optionholder has ceased to be an employee but has retained his Option as a consequence of rule 5.1, the Designated Corporate Officer retains the right to lapse his Option if, prior to the Option being exercised, the Optionholder joins a Competitor Organisation of any Member of the Group within 12 months of ceasing to be an employee. The Designated Corporate Officer will have the sole discretion to determine the definition of “Competitor Organisation”.

4.5 Ceasing to be an employee

For the purposes of these rules, an Optionholder will not be treated as ceasing to be an employee of a Member of the Group:

4.5.1 until he ceases to be an employee of all Members of the Group; or

3

4.5.2 unless the Designated Corporate Officer decides otherwise, if he recommences employment with, or becomes a director of, a Member of the Group within seven days.

5 Exercise and lapse in other circumstances – personal events

This rule 5 sets out exceptions to the general rules of exercise and lapse in rule 4.

5.1 Leaving in exceptional circumstances

5.1.1 If an Optionholder ceases to be an employee for any of the reasons set out below at least one year after the Date of Grant, his Options will not lapse and he may exercise them in accordance with rule 5.1.2. The reasons are:

(i) redundancy;

(ii) ill-health, injury, disability;

(iii) the Optionholder’s employing company ceasing to be a Member of the Group;

(iv) a transfer of the undertaking, or the part of the undertaking, in which the Optionholder works to a person which is neither under the Control of the Company nor a Member of the Group; and

(v) any other reason, if the Designated Corporate Officer so decides in any particular case.

5.1.2 Where rule 5.1.1 applies, if the Optionholder ceases to be an employee:

(i) before Vesting, he may exercise his Option within one year of Vesting,

(ii) on or after Vesting, he may exercise his Option within one year of the date he ceases to be an employee.

The Option is only exercisable to the extent that any condition has been satisfied.

5.1.3 In addition, if either of rules 5.1.1(i), 5.1.1(iii) or 5.1.1(iv) apply unless the Designated Corporate Officer decides otherwise, the extent to which the Option is exercisable will be reduced pro rata to reflect any period during which the Optionholder was not an employee between the Date of Grant and Vesting.

5.1.4 The Designated Corporate Officer must exercise any discretion provided for in rule 5.1.1(v) within 80 days after cessation of the relevant Optionholder’s employment. If the Designated Corporate Officer allows an Optionholder to exercise his Option in accordance with rule 5.1.1(v) he will set the period during which the Option can be exercised but this may not be longer than one year from the date the Optionholder ceases to be an employee, unless the Designated Corporate Officer determines otherwise in any particular case. The Designated Corporate Office may also impose any other conditions.

5.2 Death

If an Optionholder dies, his Options may be exercised by his personal representatives in full up to one year from his death.

4

5.3 Career breaks

5.3.1 If an Optionholder is on a Career Break on the date that his Option would Vest under the Plan, then unless the Designated Corporate Officer determines otherwise in any particular case, the Option will only become exercisable after the Designated Corporate Officer determines that the Optionholder has returned to normal employment at the end of the Career Break and has continued to be in his normal employment for a period of three months from the date of return, and in that period has not given or received notice of termination of employment.

5.3.2 Unless any of the reasons set out in rules 5.1, 5.2 or 6 apply, if the Optionholder ceases to be an employee of any Member of the Group before having returned to normal employment at the end of the Career Break or during the three month period referred to in rule 5.3.1, then his Option will lapse on cessation of employment. If any of the reasons set out in rules 5.1, 5.2 or 6 do apply, his Option will become exercisable in accordance with those rules.

5.4 Overseas transfer

This rule applies if an Optionholder is transferred to work in another country, and, as a result of that transfer, the Optionholder may either:

5.4.1 suffer a tax disadvantage in relation to his Options (this being shown to the satisfaction of the Designated Corporate Officer); or

5.4.2 become subject to restrictions on his ability to exercise his Options or to hold or deal in the Shares or the proceeds of the sale of the Shares acquired on exercise because of the security laws or exchange control laws of the country to which he is transferred.

If the Optionholder continues to hold an office or employment with a Member of the Group, the Designated Corporate Officer may permit the Optionholder to exercise the Option to such extent as he determines and during the period starting three months before and ending three months after the transfer takes place. If the Optionholder does not exercise his Options, following this rule 5.4, the usual exercise rules will apply to him at the appropriate times.

6 Exercise and lapse in other circumstances – corporate events

6.1 Takeovers

6.1.1 This rule 6.1 does not apply if Options are to be replaced in accordance with rule 6.4.

6.1.2 This rule applies where a person (or a group of persons acting in concert) obtains Control of the Company as a result of making an offer to acquire Shares.

6.1.3 When this rule applies, Options may be exercised (subject to any condition set in accordance with rule 1.3) until the earlier of:

(i) the date six months after the date on which the person making the offer has obtained Control of the Company; and

(ii) six weeks after the date on which a notice to acquire Shares under Section 979 of the Companies Act 2006 or any other equivalent local legislation is first served.

5

6.2 Company reconstructions

6.2.1 This rule does not apply if Options are to be replaced in accordance with rule 6.4.

(i) a court sanctions a compromise or arrangement in connection with the acquisition of Shares; or

(ii) there is any other local equivalent to that sanction procedure.

6.2.3 When this rule applies, Options may be exercised (subject to any condition set in accordance with rule 1.3) within six months after the date of the sanction. Any Option not so exercised will lapse at the end of that period.

6.3 Demergers and other significant distributions

This rule does not apply if Options are to be replaced in accordance with rule 6.4.

If the Designated Corporate Officer becomes aware that the Company is or is expected to be affected by any demerger, dividend in specie, super dividend or other transaction not falling within rule 6.1 or 6.2 which, in the opinion of the Designated Corporate Officer, would affect the current or future value of any Option, the Designated Corporate Officer may, acting fairly, reasonably and objectively, in his discretion, allow some or all Options to be exercised (subject to any condition set in accordance with rule 1.3). The Designated Corporate Officer will specify the period of exercise of such Options, whether the Options will lapse at the end of the period

The Designated Corporate Officer will notify any Optionholder who is affected by the Designated Corporate Officer exercising his discretion under this rule.

6.4 Mergers and reorganisations

If, as a result of events specified in rules 6.1 to 6.2.3, a company (the “Acquiring Company”) obtains Control of the Company and:

6.4.1 the shareholders of the Acquiring Company, immediately after it has obtained Control, are substantially the same as the shareholders of the Company before then; or

6.4.2 the obtaining of Control is pursuant to a merger with the Company; and

6.4.3 the Company and the Acquiring Company consent to the replacement of Options under this rule 6.4,

then Options will not become exercisable. Instead, all rights under the Plan will be replaced in accordance with rule 7.3.

6.5 Designated Corporate Officer

In rules 6.1, 6.2 and 6.2.3, “Designated Corporate Officer” means the person who was the Designated Corporate Officer immediately before the relevant event.

7 Exchange of Options

7.1 Application

7.1.1 a person (or a group of persons acting in concert) has obtained Control of the Company as a result of making an offer to acquire Shares;

6

7.1.2 a court sanctions a scheme of arrangement under Section 899 of the Companies Act 2006 (or equivalent local legislation) in connection with the acquisition of Shares or there is a local equivalent to that sanction procedure;

If this rule 7 applies, Options may be exchanged during the period of six months after the relevant event and with the agreement of the company offering the exchange.

7.3 Exchange terms

Where an Option is to be exchanged, the Optionholder will be granted a new option to replace it.

Where an Optionholder is granted a new option:

7.3.1 the new option will be in respect of shares in any body corporate determined by the company offering the exchange;

7.3.2 the new option will be equivalent to the Option that was exchanged;

7.3.3 the new option will be treated as having been acquired at the same time as the Option that was exchanged and will be exercisable in the same manner and at the same time;

7.3.4 the new option will be subject to the rules as they last had effect in relation to the Option that was exchanged; and

7.3.5 with effect from the exchange, the rest of the rules will be construed in relation to the new option as if references to Shares were references to the shares over which the new option is granted and references to the Company were references to the body corporate determined under rule 7.3.1.

8 Exercise of Options

8.1 Exercise

An Optionholder can exercise his Option validly only in the way described in, and subject to, this rule 8.

8.2 Part exercise

Subject to any other restriction in the rules, an Option may be exercised in respect of all the Shares under the Option or only some of those Shares. The Designated Corporate Officer may set a minimum limit in respect of which an Option can be exercised.

8.3 Manner of exercise

Options must be exercised in a form specified by the Company and must be accompanied by correct payment in full of the Option Price for the number of Shares being acquired or details of arrangements agreed between the Optionholder and the Company made for the payment of the Option Price for the number of Shares being acquired.

7

8.4 Option exercise date

8.4.1 Subject to rules 8.4.2, the “Option Exercise Date” will be the date of receipt by the Company or other duly appointed agent of the notice and, if appropriate, documents and the payment referred to in rule 8.3.

8.4.2 If an option exercise notice is delivered at a time when there is a Dealing Restriction, the Option Exercise Date will be the date when the Optionholder is permitted to exercise an Option following the lifting of such Dealing Restriction provided, however, this rule does not extend any period in which an Option is exercisable.

8.4.3 If an Option lapses before the Option Exercise Date, any attempted exercise of that Option is invalid. No employee has any right to compensation if an Option becomes exercisable under the Plan but lapses before the Option Exercise Date.

8.5 Transfer of Shares

Subject to rule 8.7 (Consents) following the exercise of an Option, the Designated Corporate Officer will procure that the Shares are transferred to the Optionholder within 30 days of the Option Exercise Date.

8.6 Rights

Optionholders will be entitled to all rights attaching to the Shares by reference to a record date on or after the transfer date. They will not be entitled to rights before that date.

8.7 Consents

All transfers of Shares will be subject to any necessary consents under any relevant enactments or regulations for the time being in force in the United Kingdom or elsewhere.

8.8 Articles of association

Any Shares acquired on the exercise of Options are subject to the articles of association of the Company from time to time in force.

8.9 Cash alternative

The Designated Corporate Officer may at any time determine not to procure the transfer of Shares to an Optionholder who exercises his Option, but instead to pay to him (subject to the withholding provisions in rule 8.10) a cash amount. This cash amount must be equal to the amount by which the market value of the Shares in respect of which the Option is exercised exceeds the Option Price. Alternatively, the Designated Corporate Officer may procure the transfer of Shares to the value of that cash amount. If the Designated Corporate Officer so determines, the Optionholder need not pay the Option Price or, if he has paid it, the Company will repay the Option Price to him.

8.10 Withholding, deduction and offsets

8.10.1 Any Member of the Group, duly appointed agent or trustee of any employee benefit trust may withhold such amount and make such arrangements as it considers necessary to meet any liability to taxation or social security contributions in respect of Options. These arrangements may include the sale or reduction in number of any Shares or the Optionholder discharging the liability himself.

8

8.10.2 In addition, it shall be a condition of exercise that any Member of the Group, duly appointed agent or trustee may deduct from and set off against the Shares (whether payable in cash or Shares and whenever payable) any debt, obligation, liability, or other amount owed by the Optionholder to a Member of the Group, including but not limited to amounts under an expatriate tax policy (as currently in effect or as amended from time to time), or amounts advanced on behalf of the Optionholder with respect to employment taxes, as determined in the sole discretion of the Designated Corporate Officer.

9 General

9.1 Notices

9.1.1 Any notice or other document which has to be given to an Eligible Employee or Optionholder under or in connection with the Plan may be:

(i) delivered or sent by post to him at his home address according to the records of the Member of the Group employing him;

(ii) sent by e-mail or fax to any e-mail address or fax number which according to the records of the Member of the Group is used by him; or

(iii) posted on the Company’s website

or in the case of (i) or (ii) above, such other address which the Company considers appropriate.

9.1.2 Any notice or other document which has to be given to the Company or other duly appointed agent under or in connection with the Plan may be delivered or sent by post to it at its respective registered office (or such other place as the Designated Corporate Officer or duly appointed agent may from time to time decide and notify to Optionholders) or sent by e-mail or fax to any e-mail address or fax number notified to the sender.

9.1.3 Notices sent by post will be deemed to have been given on the earlier of the date of actual receipt and the second day after the date of posting. However, notices sent by or to an Optionholder who is working overseas will be deemed to have been given on the earlier of the date of actual receipt and the seventh day after the date of posting.

9.1.4 Notices sent by e-mail or fax, in the absence of evidence of non-delivery, will be deemed to have been received on the day after sending.

9.2 Documents sent to shareholders

The Company, if it considers appropriate, may send to Optionholders copies of any documents or notices normally sent to the holders of its Shares at or around the same time as issuing them to the holders of its Shares.

9.3 Designated Corporate Officer’ decisions final and binding

The decision of the Designated Corporate Officer on the interpretation of the rules or in any dispute relating to an Option or matter relating to the Plan will be final and conclusive.

9

9.4 Costs

The Company will pay the costs of introducing and administering the Plan. The Company may ask an Optionholder’s employer to bear the costs in respect of an Option granted to that Optionholder.

9.5 Regulations

The Designated Corporate Officer has the power from time to time to make or vary regulations for the administration and operation of the Plan, but these must be consistent with the rules.

9.6 Terms of employment

9.6.1 For the purposes of this rule, “Employee” means any employee of a Member of the Group.

9.6.2 This rule 9.6 applies during an Employee’s employment and after the termination of an Employee’s employment, whether or not the termination is lawful.

9.6.3 Where a contract of employment exists for an Optionholder, nothing in the rules or the operation of the Plan forms part of the contract of employment of an Employee. Where no contract of employment exists, nothing in the rules or the operation of the Plan creates in whole or in part a contract of employment. The rights and obligations arising from the employment relationship between the Employee and his employer are separate from, and are not affected by, the Plan. Participation in the Plan does not create any right to, or expectation of, continued employment.

9.6.4 No employee has a right to participate in the Plan. Participation in the Plan or the grant of Options on a particular basis in any year does not create any right to or expectation of participation in the Plan or the grant of Options on the same basis, or at all, in any future year.

9.6.5 The terms of the Plan do not entitle the Employee to the exercise of any discretion in his favour.

9.6.6 The Employee will have no claim or right of action in respect of any decision, omission or discretion which may operate to the disadvantage of the Employee even if it is unreasonable, irrational or might otherwise be regarded as being in breach of the duty of trust and confidence (and/or any other implied duty) between the Employee and his employer.

9.6.7 No Employee has any right to compensation for any loss in relation to the Plan, including any loss in relation to:

(i) any loss or reduction of rights or expectations under the Plan in any circumstances (including lawful or unlawful termination of employment);

(ii) any exercise of a discretion or a decision taken in relation to an Option or to the Plan, or any failure to exercise a discretion or take a decision; or

(iii) the operation, suspension, termination or amendment of the Plan.

9.6.8 Participation in the Plan is permitted only on the basis that the Optionholder accepts all the provisions of the rules, including this rule 9.6. By participating in the Plan, an Employee waives all rights under the Plan, other than the right to exercise an Option subject to and in accordance with the express terms of the rules.

10

9.6.9 Nothing in this Plan confers any benefit, right or expectation on a person who is not an Employee. No such third party has any rights under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of this Plan. This does not affect any other right or remedy of a third party which may exist.

9.7 Employee trust

The Company and any Member of the Group may provide money to the trustee of any trust 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 682 of the Companies Act 2006.

9.8 Data protection

By participating in the Plan, the Optionholder consents to the holding and processing of personal data provided by the Optionholder to any Member of the Group, trustee or third party service provider for all purposes relating to the operation of the Plan. These include, but are not limited to:

9.8.1 administering and maintaining Optionholder records;

9.8.2 providing information to Members of the Group, trustees of any employee benefit trust, registrars, brokers or third party administrators of the Plan;

9.8.3 providing information to future purchasers of the Company or the business in which the Optionholder works; and

9.8.4 transferring information about the Optionholder to a country or territory outside the European Economic Area that may not provide the same statutory protection for the information as the Optionholder’s home country.

10 Changing the Plan and termination

10.1 Designated Corporate Officer’s powers

The Designated Corporate Officer may change or terminate the Plan at any time with or without prior notification to the Optionholders. However, Options granted before such termination will continue to be valid and will be exercisable as described in these rules.

10.2 Notice

The Designated Corporate Officer may give written notice of any changes made to or termination of the Plan to any Optionholder affected.

(ii) a US Optionholder’s involuntary termination of employment with any Member of the Group, other than due to such Optionholder’s conduct or performance. For avoidance of doubt, the following circumstances will be considered an involuntary termination of employment: (a) termination of a US Optionholder’s employment by his or her employer with no anticipated return to employment with a Member of the Group, or a termination considered by the Designated Corporate Officer to have been initiated by the US Optionholder’s employer with no anticipated return to employment with a Member of the Group, in both cases where the termination is not based on the US Optionholder’s conduct or performance; or (b) termination of a US Optionholder’s employment as a result of a Change in Control. A transfer of employment from one Member of the Group to another will not be considered a termination of employment, nor will a reduction in hours, unless such is considered an involuntary termination of employment within the meaning of Section 409A of the Code.

If the terms of a grant, Vesting or exercise of Options are amended or terminated, the Company is under no obligation to provide any consideration or remuneration in lieu of the grant, Vesting and/or exercise of Options.

All taxes, penalties, or interest imposed on any Optionholder due to any failure to comply with Section 409A of the Code or other tax rule shall be the Optionholder’s responsibility and no Member of the Group shall have any obligation to keep the Optionholder whole.
