Griffin Capital Essential Asset REIT Enters into Definitive Merger Agreement with Signature Office REIT

El Segundo, Calif. (November 24, 2014) – Griffin Capital Corporation (“Griffin Capital”) announced today, on behalf of Griffin Capital Essential Asset REIT, Inc. (“GCEAR”), the execution of an Agreement and Plan of Merger between GCEAR and Signature Office REIT, Inc. (“Signature”) pursuant to which Signature will merge into GCEAR. The merger was unanimously approved by each REIT’s respective Board of Directors. The proposed transaction is conditioned on formal approval by Signature shareholders, receipt of required regulatory approvals and other customary closing conditions, and is expected to be completed during the first half of 2015.

The contemplated merger will involve a stock-for-stock transaction whereby GCEAR will issue 2.04 shares of stock of GCEAR for each Signature share of stock. As part of the transaction, GCEAR will refinance Signature’s existing debt as of September 30, 2014 of approximately $159 million with proceeds from GCEAR’s existing credit facility from a consortium of financial institutions led by Key Bank National Association and Bank of America, N.A. Kevin Shields, the current Chairman and Chief Executive Officer of GCEAR, and the GCEAR executive team will continue to lead the combined company.

The vast majority of Signature’s net asset value is embedded in a real estate portfolio comprised of 15 buildings, encompassing over 2.6 million square feet, situated across eight states which were all originally acquired from late 2010 through 2012, near the bottom of the current real estate cycle. This real estate portfolio is highly complementary to GCEAR’s existing portfolio, which is primarily comprised of single-tenant office and industrial real estate assets that serve as key operating facilities for a diverse and robust roster of blue-chip, Fortune 500 companies.

Commenting on the merger, Kevin Shields, Griffin Capital’s Chairman and Chief Executive Officer stated, “As we look forward to the next phase of our lifecycle, we believe the additional scale, diversity and operating efficiencies that our combined portfolios will garner is paramount in driving additional stockholder value in the future. Earlier this year we sold all of the remaining capital stock in our follow-on offering, and once we fully invest this equity, we expect our total capitalization to exceed $3 billion upon stabilization.”

Michael Escalante, Griffin Capital’s Chief Investment Officer added, “We look forward to having Signature shareholders standing shoulder-to-shoulder with GCEAR and its management team, which has invested over $26 million of its own capital in GCEAR. We are excited about this opportunity and, in our opinion, a ‘win-win’ scenario was engendered by the understanding that together we can accomplish more than we can apart.”

Signature was represented by the Eastdil Secured group of Wells Fargo Securities, LLC, and Houlihan Lokey Financial Advisors, Inc. acted as financial advisors to Signature. Robert A. Stanger & Co. provided GCEAR’s Board of Directors with a fairness opinion for the transaction.
