JP Morgan Cazenove is acting as a financial adviser for Heritage during the sale of its stake in Miran Block to Genel Energy. It has worked with Heritage since its IPO back in 2008. Barry Weir, James Taylor and Neil Haycock are the lead advisers on the deal. Weir, who heads the natural resources team at JP Morgan Cazenove, has worked on several deals this year. In February, he advised the buyout firm TPG Capital on a takeover of GlobeOp Financial. He has also, alongside Neil Passmore and Ian Hannam, worked on the Xstrata and Glencore merger. Additionally, Weir worked on the merger of Kama Mining Company with Uralkali. Last year he was part of the advisory team working with Gem Diamonds regarding a possible merger with Lucara. Meanwhile, Taylor and Haycock worked on the Essar Energy IPO back in 2010. The JP Morgan Cazenove trio – Weir, Taylor and Haycock – have been working with Heritage this year on the £237m rights issue, and on the proposed acquisition of OML 30 in Nigeria.
