                                (the "Company")

                            Result of Tender Offer                             

The Company today announces the result of the Tender Offer set out in the
circular published by the Company on 16 May 2011 (the "Circular") which closed
at 3.00 p.m. on 1 June 2011 following shareholder approval at a General Meeting
of the Company held at 12.00 p.m. on 1 June 2011.

65,911,929 Wood Group Shares were tendered and will be purchased by J.P. Morgan
Cazenove at a price per share (referred to as the "Strike Price") of 625 pence
per Wood Group Share, for a total cost of £411.9 million. This represents
approximately 12.2 per cent. of the issued share capital of the Company.

As set out in the Circular, the Company will buy back from J.P. Morgan Cazenove
the Wood Group Shares which are to be purchased by J.P. Morgan Cazenove under
the Tender Offer. The Company then intends to cancel such Wood Group Shares,
reducing the issued share capital from 540.8 million shares to 474.9 million
shares (the "Revised Share Capital").

In accordance with the terms of the Tender Offer, all Wood Group Shares validly
tendered will be accepted and purchased in full. It is anticipated that the
proceeds payable to Wood Group Shareholders for the certificated Wood Group
Shares purchased under the Tender Offer will be sent on 7 June 2011 in the form
of a cheque and that CREST account holders will have their CREST accounts
credited by 3 June 2011.

Trusts established for the benefit of members of the Wood family and for
certain charitable causes (the "Trusts") tendered 58,487,278 shares in line
with their stated intention to diversify their highly concentrated position of
Wood Group shares within their investment portfolios. This will result in a
reduction in the holding of the Trusts from 63.5 million shares, being
approximately 11.7 per cent. of the issued share capital prior to the Tender
Offer, to 5.0 million shares, being approximately 1.1 per cent. of the Revised
Share Capital. Sir Ian Wood, along with the other Directors, has not tendered
any shares.

As indicated in the Circular, the Board will seek to return the balance of the
£1.05 billion of cash to Wood Group Shareholders by means of a separate B share
scheme, details of which will be announced shortly.

Capitalised terms used in this announcement have the same meaning as ascribed
to them in the Circular.
