announce an agreement today that will support the future growth of CMG
Mortgage Insurance Company (CMG MI). Under the business arrangement, Arch
Capital Group Ltd., through its U.S.-based subsidiaries (Arch U.S. MI), will
acquire all outstanding equity interests in CMG MI from PMI and CUNA Mutual
Group.

CMG MI is jointly owned by PMI and CUNA Mutual Group.

CUNA Mutual Group will enter into distribution and reinsurance agreements with
CMG MI, continuing CMG MI's private mortgage insurance offerings to credit
unions. The transactions with Arch U.S. MI are expected to close within 12
months, subject to approval of the Arizona receivership court, regulatory
approvals and satisfying other customary closing conditions.

"Our goals have been consistent from the start of this process: Protect
policyholders, deliver strong service to customers, and aim for a long-term,
viable solution for credit unions to have a private mortgage insurer that is
sensitive to, and understands their unique mission," said Jeff Post, President
& CEO, CUNA Mutual Group. "Through its significant financial resources and
risk management expertise, the agreement with Arch supports the stability and
future growth of CMG MI."

"We are confident that, following the purchase of CMG MI by Arch, CMG MI will
continue to provide the customer-focused products and services that have made
CMG MI the long-standing market leader in meeting the mortgage insurance needs
of credit unions."

Arch U.S. MI will purchase PMI's information technology platform and systems
and, as a result, CMG MI is expected to enjoy uninterrupted delivery of
technology support for its operations. With the proposed distribution
arrangement, CUNA Mutual Group mortgage insurance sales staff will continue to
serve credit union customers on behalf of CMG MI.

"In order to ensure uninterrupted access to a best-in-class origination and
servicing platform, talented underwriting and back-office support, we wanted
to find a buyer who had the capability and expertise to continue investing in
this unique business," said Sean Dilweg, CUNA Mutual Group vice president and
product executive for CMG MI. "We are confident Arch U.S. MI more than
fulfills all of these requirements."

"Similar to our successful partnerships with Liberty Mutual and State National
Companies, CUNA Mutual Group will use its marketplace knowledge and
distribution strengths, combined with Arch's financial strength and commitment
to mortgage insurance, to bring a stronger product solution to its credit
union customers. We look forward to a strong partnership with Arch."

staff will be joining Arch. Together with our senior executives, they will
form an industry leading team with broad capabilities to meet our clients'
needs over the long term," said Marc Grandisson, Chairman and CEO of Arch
