Business Wire

BOGOTÁ, Colombia -- December 9, 2013

An investor group led by global private equity firm Advent International today
announced that it has signed a definitive agreement to acquire a minority
interest in Oleoducto Central S.A. (“Ocensa”), Colombia’s largest crude oil
transportation system. Colombia’s two largest pension funds—Sociedad
Administradora de Fondos de Pensiones y Cesantías Porvenir S.A. (“Porvenir”)
and Administradora de Fondos de Pensiones y Cesantía Protección S.A.
(“Protección”)—will join Advent, through a co-investment fund formed by Advent
as a sponsor (“LAPEF V OC Co-Investment LP”), in purchasing approximately 22%
of Ocensa from Talisman Energy Inc. (“Talisman”), Total Colombia Pipeline
(“Total”) and Compañía Española de Petróleos S.A.U. (“CEPSA”). Cenit S.A.S.
(“Cenit”), a wholly owned subsidiary of Ecopetrol S.A., Colombia’s largest
integrated oil and gas company, will retain majority ownership of Ocensa.
Completion of the transaction is subject to customary closing conditions and
is expected to take place within the next few weeks.

Established in 1994, Ocensa manages Colombia’s largest crude oil pipeline. The
system has an average pumping capacity of 590,000 barrels per day, with eight
stations and four distinct segments extending nationally over a length of 830
kilometers. It is the main pipeline between Colombia’s Llanos region and the
Atlantic Coast and moves approximately 60% of Colombia’s crude oil production,
which represents roughly 70% of all exports coming out of the country.

The Advent-led investor group will work closely with Cenit and the company’s
management team to support the continued growth of the business. Ocensa is
strategically well positioned to manage the continued expansion of Colombia’s
crude oil output, which has nearly doubled in the past six years and is
expected to increase further in the coming years. Ocensa’s system is running
at close to 100% utilization, and the company has begun a staged expansion
project to increase capacity by approximately 30%.

“We are pleased to welcome the Advent-led investor group as new investors in
Ocensa, and we are excited to continue working with all of our shareholders to
grow the company and ensure this critical asset maintains its proven track
record of safety and reliability,” said Luisa Lafaurie, President of Ocensa.
“We also would like to thank Talisman, Total and CEPSA for their contributions
to our success.”

Mauricio Salgar, a Managing Director at Advent and head of its Bogotá office,
commented, “Ocensa is a core strategic asset for Colombia given the importance
of oil exports to the country’s economy. Additionally, the company operates
the most cost-efficient and reliable pipeline in the country and has an
attractive business model. We look forward to applying our expertise and
working with our new partners to ensure that the company maintains its
leadership position while continuing to meet the infrastructure needs of
Colombia’s expanding energy industry.”

Gurinder Grewal, a Principal in Advent’s Boston office who helps coordinate
the firm’s global activities in the energy sector, said, “Ocensa is our fourth
transaction in the energy sector in the past three years, following
investments in BOS Solutions, NCS Energy Services and P2 Energy Solutions, and
highlights our growing and now global activity in the sector. As with our
other investments, we are excited to be partnering with a great management
team and look forward to working with them in the coming years."

Hal Kvisle, Talisman CEO, said, “The Ocensa pipeline forms an integral part of
Colombia’s crude oil transportation system, and retaining our capacity rights
through this transaction enables Talisman to maintain our competitive
advantage, transporting oil from our own operations and generating third-party
revenue from any surplus capacity.”

Ladislas Paszkiewicz, President, Americas for Total Exploration & Production,
commented, “The Ocensa story is a successful one, and we’ve been very proud to
have been associated with it since the beginning. Ocensa has a bright future
with some sound expansion projects in a tight transportation market, and we
are confident that Advent International and its partners will provide valuable
input. As Total is retaining all of its transportation rights with Ocensa
through its local subsidiary Total E&P Colombie, we will continue to be
involved in the oil transportation activity in Colombia.”

Pedro Miró, CEPSA CEO, commented, “The Ocensa management, jointly with its
shareholders, have over time created a very professional company, which I am
sure will remain so in the future. Advent’s participation is a step forward in
consolidating Ocensa as a pipeline operator, while upstream companies like
ours will focus on increasing oil and gas production from Colombian fields,
both current and new to come.”

Ocensa is Advent’s third investment in Colombia since opening its Bogotá
office in 2011 and fits with the firm’s strategy of investing in sectors where
it has deep expertise globally, including energy, pharmaceuticals and
financial services. In November 2011, Advent acquired a majority interest in
Biotoscana, a licensor and marketer of specialty pharmaceutical products in
Colombia, and in June 2013 it agreed to acquire 50% of Alianza Fiduciaria, the
country’s leading independent trust and asset management company. Advent has
been investing in Latin America for 17 years, during which time it has backed
47 companies across eight countries.

J.P. Morgan Securities LLC (lead advisor), Banco Itaú BBA S.A., Citigroup
Global Markets Inc. and Natixis, New York Branch provided financial advice to
Advent on the Ocensa investment. Banco Itaú BBA S.A., Citigroup Global Markets
Inc. and Natixis, New York Branch provided committed financing for the
transaction. Gómez-Pinzón Zuleta Abogados S.A. and Weil, Gotshal & Manges LLP
acted as legal counsel, and Ernst & Young Ltda. (lead advisor) and KPMG LLP
acted as tax advisors to Advent. Talisman was jointly advised by BMO Nesbitt
Burns Inc. and Credit Suisse Securities. Total and CEPSA were advised by TD
Securities.
