EMERYVILLE, California, February 23, 2010 - Alibris Holdings, Inc, owner of Alibris (www.alibris.com), Inc.,
the premier online marketplace for sellers of new and used books, music, and
movies, announced today that it is acquiring Monsoon
(www.monsoonworks.com), Inc., an Oregon-based marketplace selling
solutions company, for a combination of cash and stock in Alibris Holdings.
Oak Hill Capital, a private equity firm that acquired Alibris Holdings in

financing from Square 1 Bank. After the merger closes, which is expected by
early March, Alibris and Monsoon will continue to operate as separate
businesses under their existing names.

"We are excited to be working even more closely with Monsoon," said Brian
Elliott, president and CEO of Alibris Holdings. "Alibris has been focused on
driving sales for our network of more than 15,000 independent sellers through
Alibris-branded marketplaces and by providing marketplace functionality to
leading book, music, and movie retailers. Monsoon provides best-in-class
tools and services for sellers listing across multiple marketplaces. We
believe that this merger will provide our sellers with unparalleled
marketplace exposure, and further opportunities for growth."

Monsoon Chief Executive Officer Kanth Gopalpur, who will continue as CEO
and join the Alibris Holdings executive management team post-transaction,
said, "This transaction will provide the combined Monsoon-Alibris customer
base with even more opportunities to expand their businesses and increase
sales. We will be able to take advantage of additional resources, technology,
and capital in order to deliver more and better solutions to grow our
customers' businesses on all online marketplaces."

Leveraging the best of what each company has to offer, the
Monsoon-Alibris merger will broaden sellers' reach, giving them increased
sales potential with the best tools, world-class customer support, and an
extensive network of business partnerships, including Amazon.com, Barnes &
Noble, Borders, Chapters Indigo, eBay, and Waterstone's. Monsoon will
continue to run as a separate operating company led by Kanth Gopalpur and the
Monsoon senior management team. Combined, Alibris and Monsoon managed more
than US$400 million of book, music, movie, and videogame sales for its
sellers in 2009.

"Online sellers recognize the need to manage their presence across all
major online shopping destinations. Similarly, traditional retailers
recognize that offering a marketplace to their customers provides them with
significant selection gains," said Robert Morse, partner with Oak Hill
Capital Partners. "With more than US$400 million in annual sales across the
Alibris-Monsoon network, the combined company is an important partner for
both online sellers and major online shopping destinations. We are committed
to supporting the future growth of Alibris and Monsoon."

Alibris Holdings was advised by the law firm Wilson, Sonsini, Goodrich &
Rosati. Monsoon was advised by the law firm Tonkon Torp.
