On February 27, 2013, Calpian Inc. (the “Company”) entered into an asset purchase agreement by and among the Company, Pipeline Data Inc., Securepay.com Inc., Northern Merchant Services Inc., Pipeline Data Processing Inc., Pipeline Data Portfolio Acquisitions Inc., Aircharge Inc., PayPipe Inc., Paynet Systems Inc., PayPassage Inc., and Valadata Inc. (collectively “Sellers”).

The Sellers are in the business of providing an integrated suite of merchant payment processing services and related software enabling products, and delivering credit and debit card-based payments processing solutions to small and mid-sized merchants operating in physical “brick and mortar” business environments and/or over the Internet. The Sellers filed for bankruptcy protection under Chapter 11 in November 2012, and the Company plans to acquire certain assets and liabilities pursuant to the terms and conditions as determined by the bankruptcy court and reflected in the purchase agreement.

Pursuant to the terms and conditions of the purchase agreement, the Company intends to acquire certain assets and liabilities of the Sellers in consideration of a cash payment of $9,750,000. The closing of the transaction described herein is intended to occur on March 15, 2013, or such other date as the Buyer and Sellers may determine. The assets to be acquired include, without limitation: merchant contracts, accounts receivable, intellectual property, assumed contracts and leases, equipment and fixtures, and miscellaneous additional tangible and intangible assets.

The Company intends to assume selected liabilities of the Sellers which include, without limitation: certain contractual obligations arising after the closing, certain cure payments related to the assumed contracts, obligations to refund certain merchant cash reserves under the assumed contracts, and other miscellaneous liabilities listed as part of the agreement.

The purchase agreement contains representations and warranties typical to a transaction of its type, and may be terminated by either party only in limited and specific situations.

The acquisition described above was financed by expanding the Company’s senior credit facility with Granite Hill Capital Ventures, LLC from $5 million to $15 million under similar terms and conditions as previously existing.

The foregoing description of the purchase agreement is a summary only and is qualified in its entirety by reference to the full text of the agreement, which the Company will file following closing as an exhibit to its annual report on Form 10-K, expected to be filed on or before March 31, 2013.
