(London/New Jersey, 7 May 2009) Yorkville Advisors, LLC (Yorkville), the US based investment manager to a family of funds, is pleased to announce that it has entered into a £30 million Standby Equity Distribution Agreement (SEDA) with AIM listed Gulf Keystone Petroleum Ltd. (AIM: GKP), an independent oil and gas exploration and production company with assets in Algeria and the Kurdistan Region of Iraq (Kurdistan).

Gulf Keystone entered into the SEDA as a means of raising additional financing, as and when required, to fund its existing and developing activities in the Kurdistan region of Iraq and Algeria, and in order to take advantage of potential opportunities and successes that may arise.

Pioneered 8 years ago by Yorkville, a SEDA offers companies low risk, cost effective ways to optimise their capital structure in pursuit of their growth strategy. The SEDA enables Gulf Keystone, at its discretion, to request funds of up to £30 million in tranches, in exchange for the issue of new equity, on terms related to the market price at each drawdown, up to 36 months from the signing of the agreement.

Ewen Ainsworth, Chief Financial Officer, Gulf Keystone said: “We see the SEDA as one element of our overall financing, which is there to compliment existing arrangements and projects. By its very nature, it also provides us with the wherewithal to react quickly to any successes or new acreage opportunities.”

Paul Strzelecki, Managing Director, Yorkville Advisors UK, said: “The SEDA will give Gulf Keystone more opportunity to exploit favourable circumstances as and when needed, combined with a degree of certainty over future cash flow needs.”
