Haynes and Boone, an international law firm based in Texas, and MMA Lawyers, a Brazilian law firm, announced a cooperation agreement to better serve clients in Brazil, the US, China, and globally.

The agreement aims to benefit clients of both firms seeking legal services between Brazil, the US, and Asia.

1. Haynes and Boone, MMA Lawyers of Rio de
Janeiro Announce Cooperation Agreement
Expanding Latin America Capabilities
DALLAS / RIO DE JANEIRO – Haynes and Boone, LLP and MMA Lawyers of Brazil
announced today that they have begun working together under a cooperation agreement to
serve clients in Brazil, the United States, China and around the world.
Under this new arrangement, Haynes and Boone clients will benefit from the experience of
MMA inside one of the world’s strongest emerging markets with a vibrant energy base and
growing trade links to Texas and the rest of the U.S.
MMA’s clients, meanwhile, will benefit from having access to the breadth and depth of the
Haynes and Boone U.S. and international practices outside of Brazil.
“Teaming up with MMA is a big step toward maintaining our identity as one the top
international law firms with a focus on Latin America,” said Haynes and Boone Managing
Partner Terry Conner. “This helps us to provide an expanded array of services to a broad
range of new and evolving clients. The announcement today is the culmination of more than
two years of work, and is an important enhancement to our well-recognized Latin American
practice.”
Said Marcelo Mello, MMA Lawyers managing partner: “It is with great pride that we formalize
our already strong relationship with Haynes and Boone. Through such cooperation, our firms
will provide an extraordinary level of service to sophisticated multinational clients from the
U.S. and beyond. As founder of this firm, I could not be more proud.”
The cooperation agreement will allow MMA and Haynes and Boone partners to work
together closely, although the firms will remain independent.
Encompassing more than 20 years of experience in operations and projects for various
multinational companies and industries, MMA Lawyers is active in more than 30 countries
across the Americas, Europe, Asia and Africa.
MMA Lawyers combines lawyers from leading businesses and law firms from Brazil in a
multidisciplinary team of practical experience gained through decades of cross-border
projects, bringing together a range of practice areas such as civil law, tax, regulatory,
corporate, environmental, labor and employment, litigation, arbitration and dispute
resolution.

2. Prior to forming his own firm, Mello was for nearly two decades the international legal
division manager for Petrobras, the state-owned Brazilian petroleum and energy company.
Petrobras currently ranks as the world’s fifth-largest oil producer by market value.
Conner said that, consistent with the Brazilian Bar rules, “our firm will not practice Brazilian
law, so this cooperation agreement will help Haynes and Boone handle ‘southbound’ Brazil-
focused projects.” He predicted they will include transactions emanating from the U.S. and
Asia in such sectors as energy, oil field services, infrastructure, mining, project finance,
antitrust, intellectual property, finance, franchise and litigation / arbitration. Meanwhile
through MMA, Haynes and Boone expects to bring in more “northbound” work from Brazil in
such areas as energy, M&A, joint ventures, finance, intellectual property, antitrust, FCPA
compliance and litigation / arbitration, he said.
“By increasing our cross-border energy work, the MMA alliance should also help strengthen
our Houston and energy practices, experience and reputation,” Conner said.
The cooperation agreement will also foster deeper relationships with Chinese and other
Asian clients who are doing considerable business in Brazil, creating a “Brazil-China-U.S.”
triangle that supports both firms’ inbound Asia strategy, he said.
The Haynes and Boone Latin American practice has been recognized as one of the leaders
in Latin America by numerous business organizations and publications, including Latin
Lawyer and Chambers Latin America 2012, which for the third consecutive year singled out
the firm for its high-end corporate and financial work.
With more than 50 Latin America-focused attorneys based in Texas, New York, Washington,
D.C. and Mexico, Haynes and Boone maintains one of the largest such practices of any firm
headquartered in North America. Its approximately 20 Mexico City-based attorneys have a
wide range of experience in mergers and acquisitions, capital markets, finance, energy and
natural resources, real estate, bankruptcy and restructuring, international arbitration and
international trade.
Recently, for example, Haynes and Boone represented Tarahumara Pipeline, S.de R.L. de
C.V, a subsidiary of Grupo Fermaca, which has been selected as the winning bid in a public
auction by the Mexican Federal Electricity Commission (CFE) to build and operate the
natural gas pipeline for the northern region of Mexico in the state of Chihuahua. The pipeline
will be 380 kilometers in length and cost more than US $440 million to build.
