Capitol Acquisition Corp. and Two Harbors Investment Corp. to

Merge, Form New Residential Mortgage REIT Managed by an Affiliate

of Pine River Capital Management

Veteran Pine River Investment Team with Proven Track Record Well Positioned to

Capitalize on Unprecedented Dislocation in RMBS Market

NEW YORK, June 11, 2009 – Capitol Acquisition Corp. (“Capitol”) (NYSE Amex: CLA), a public investment vehicle, Pine River Capital Management L.P., a multi-strategy asset management firm with over $800 million in assets under management, and Two Harbors Investment Corp. (“Two Harbors”), a newly organized real estate investment trust (REIT) announced today that they have signed an agreement and plan of merger pursuant to which Capitol will be acquired by Two Harbors. Two Harbors intends to focus on residential mortgage backed securities and will be externally managed by PRCM Advisers LLC (“PRCM”), a subsidiary of Pine River Capital Management L.P. (“Pine River”). The transaction is expected to be completed by the end of the third quarter of 2009, pending approval by Capitol’s stockholders and warrant holders and subject to certain closing conditions, including the amendment of Capitol’s charter to remove certain provisions customarily contained in the charters of special purpose acquisition companies, in order to permit the merger.

“We believe Two Harbors represents a compelling opportunity for investors to capitalize on historically unprecedented values in the $11 trillion U.S. mortgage market,” said Mark Ein, Chairman and Chief Executive Officer of Capitol who will become Vice Chairman of Two Harbors upon completion of the transaction. “We are excited to partner with Pine River and their veteran team with a proven track record of investing in residential mortgage backed securities. We believe that Two Harbors, as a newly formed REIT, created at or near book value with no legacy assets, will be well positioned to generate attractive risk-adjusted returns,” added Mr. Ein.

Two Harbors intends to pursue a relative value strategy targeting all subsets of the RMBS market. This strategy seeks to capture inefficiencies created by the current dislocations in non-Agency and Agency securities, and longer-term opportunities in residential mortgage assets.

Under the terms of the merger agreement, the common stock of Capitol issued through Capitol’s November 2007 initial public offering will convert on a share-for-share basis into 100% of the common stock of Two Harbors. Capitol’s founders will retire 100% of their pre-IPO founders’ shares. As a condition of the transaction, Capitol’s warrant holders will be asked to amend the strike price of their warrants to $11.00 per share in exchange for extending the warrant expiration by one year to November 7, 2013.

“We are delighted to partner with the Capitol team to create an efficient public vehicle for investors to access the RMBS market,” said Brian Taylor, Founder and Chief Executive Officer of Pine River who will serve as Chairman of Two Harbors upon completion of the transaction. “Together with Capitol’s team of accomplished investors and executives, we look forward to offering Pine River’s expertise in portfolio management and mortgage backed securities to a new group of investors,” added Mr. Taylor.
