Pro rata accelerated non-renounceable entitlement offer – Notification to Ineligible Retail Shareholders

On 9 October 2017, WorleyParsons Limited (ABN 17 096 090 158) (“ WorleyParsons ” or the “ Company ”) announced that it was conducting a capital raising by way of a pro rata accelerated non-renounceable entitlement offer to eligible shareholders to subscribe for 1 new WorleyParsons share (“ New Shares ”) for every 10 existing WorleyParsons shares (“ Existing Shares ”) held at 7:00pm (Sydney time) on Wednesday, 11 October 2017 (“ Record Date ”) to raise approximately A$322 million (“ Entitlement Offer ”).

The proceeds of the Entitlement Offer will be used by WorleyParsons to fund its acquisition of AFW UK Oil & Gas Limited (“AFW UK”).

UBS AG, Australia Branch is Lead Manager and Underwriter of the Entitlement Offer (the “ Lead Manager ”).

This notice is to inform you about the Entitlement Offer and to explain why you will not be able to subscribe for New Shares under the Entitlement Offer. This letter is not an offer to issue Entitlements or New Shares to you, nor an invitation for you to apply for Entitlements or New Shares. You are not required to do anything in response to this letter.

What is the Entitlement Offer?

The Entitlement Offer comprises an institutional entitlement offer (“ Institutional Entitlement Offer ”) and an offer to Eligible Retail Shareholders (as defined below) to participate on the same terms (“ Retail Entitlement Offer ”). The Entitlement Offer is being made by the Company in accordance with section 708AA of the Corporations Act 2001 (Cth) (“ Act ”) as modified by Australian Securities and Investments Commission Corporations (Non-Traditional Rights Issues) Instrument 2016/84, meaning that no prospectus or other disclosure document needs to be prepared.

The Institutional Entitlement Offer has already closed and the results were announced to the Australian Securities Exchange (“ ASX ”) on Wednesday, 11 October 2017. WorleyParsons has today lodged a retail offer booklet with the ASX, which sets out further details in respect of the Retail Entitlement Offer (“ Retail Offer Booklet ”).

What is the Retail Entitlement Offer?

The Retail Entitlement Offer involves an offer to Eligible Retail Shareholders of an entitlement to subscribe for 1 New Share for every 10 Existing Shares held at 7:00pm (Sydney time) on the Record Date, at a price of A$13.00 (“ Offer Price ”) for each New Share (“ Entitlement ”).

As with the Institutional Entitlement Offer, the Retail Entitlement Offer is non-renounceable. A number of New Shares equal to the number that you would otherwise be entitled to subscribe for under the Retail Entitlement

Samples/000001/000001

Offer, had you been an Eligible Retail Shareholder (as defined below), will be subscribed for by the Lead Manager and sub-underwriters at the Offer Price (as defined above). As a result, no amount will be payable by you and you will not otherwise receive any value for Entitlements in respect of any New Shares that would have been offered to you if you were an Eligible Retail Shareholder.

Who is eligible?

“ Eligible Retail Shareholders ” are those persons who:

• a) are registered as a holder of Existing Shares as at 7:00pm (Sydney time) on the Record Date;

• b) have a registered address on WorleyParsons' share register in Australia or New Zealand (or are a shareholder that WorleyParsons has otherwise determined is eligible to participate);

• c) are not in the United States and are not a person (including nominees, trustees or custodians) acting on behalf of a person in the United States (to the extent such a person holds securities in WorleyParsons for the account or benefit of such persons in the United States);

• d) were not invited to participate (other than as nominee, trustee or custodian in respect of other underlying holdings) in the Institutional Entitlement Offer and were not treated as an Ineligible Institutional Shareholder (as defined below) under the Institutional Entitlement Offer; and

• e) are eligible under all applicable securities laws to receive an offer under the Retail Entitlement Offer without a prospectus, disclosure document or any lodgement, filing, registration or qualification.

“ Ineligible Institutional Shareholders ” are those persons who were identified as an institutional shareholder by WorleyParsons and are not Eligible Institutional Shareholders (as defined in the Retail Offer Booklet).

“ Ineligible Retail Shareholders ” are those persons who were not identified as an institutional shareholder by WorleyParsons and are not Eligible Retail Shareholders.

Why am I not eligible to participate in the Retail Entitlement Offer?

Unfortunately, according to our records you do not satisfy the criteria for an Eligible Retail Shareholder. In compliance with ASX Listing Rule 7.7.1(b) and section 9A(3) of the Act, this notice is to inform you that under the terms of the Entitlement Offer, you are not entitled to participate in the Retail Entitlement Offer and as such, you will not be offered any New Shares or Entitlements under the Retail Entitlement Offer. You will not be sent a copy of the Retail Offer Booklet.

The restrictions upon eligibility are due to a number of factors, including the legal limitations in some countries, the relatively small number of shareholders there, the small number and value of Existing Shares they hold and the potential cost of complying with regulatory requirements in those countries. Having given consideration to these factors, WorleyParsons has determined that, pursuant to Listing Rule 7.7.1(a) of the ASX Listing Rules and section 9A(3)(a) of the Act, it would be unreasonable to make the Retail Entitlement Offer to shareholders resident in any country outside of Australia and New Zealand.

As the Retail Entitlement Offer is non-renounceable, Entitlements in respect of the New Shares you would have been offered if you were an Eligible Retail Shareholder will lapse and you will not receive any payment or value for those Entitlements. Further details in respect of the Entitlement Offer (including details of eligibility) can be found on the announcements platform of the ASX (www.asx.com.au).

On behalf of the Company, we thank you for your continued support of WorleyParsons.

Yours sincerely,
