Item 3.

Source and Amount of Funds or Other Consideration

The Reporting Persons beneficially own an aggregate of 5,000,000 Shares. The aggregate purchase price of the Shares reported in this statement as beneficially owned was $7,750,000.

Item 4.

Purpose of Transaction

On August 9, 2016, PEAK6 entered into the following agreements with the Issuer in connection with the issuance and sale by the Issuer of 5,000,000 Shares to PEAK6 for a price of $1.55 per share. The following descriptions do not purport to be complete and are qualified in their entirety by reference to the terms of the agreements, which are attached hereto and incorporated by reference herein.

Purchase Agreement and Warrant

The Shares were issued and sold to PEAK6 pursuant to the terms of a purchase agreement dated as of August 9, 2016 (the Purchase Agreement), for an aggregate purchase price of $7,750,000. The Issuer also issued a warrant to PEAK6 to purchase up to 7,500,000 Shares at an exercise price of $1.74 per share pursuant to the terms of a warrant agreement (the Warrant Agreement) dated as of August 9, 2016. One-half of the shares subject to the warrant vest when the closing price of the Shares on the New York Stock Exchange equals or exceeds $2.50 per share for 15 trading days during a 30-trading day period and the remaining one-half of the shares subject to the warrant vest when the closing price of the Shares equals or exceeds $3.50 per share for 15 trading days during a 30-trading day period. The warrant has a five-year term. The Warrant Agreement provides that PEAK6 shall not have the right to exercise the warrant to the extent that after giving effect to such exercise PEAK6 would beneficially own in excess of 29.99% of the number of Shares outstanding immediately after giving effect to the issuance of shares upon such exercise; provided, however, that if this restriction results in PEAK6 being unable to exercise the warrant at the end of the five-year term, the warrant term shall be extended for an additional one year. Subject to certain conditions, the warrant is not exercisable until February 9, 2017, and therefore the Shares underlying the warrant have not been included as beneficially owned in this Schedule 13D.

The Shares issued pursuant to the Purchase Agreement, the warrant and the Shares issuable upon exercise of the warrant have not been registered under the Securities Act of 1933, as amended (the Securities Act). Pursuant to the terms of the Purchase Agreement, the Issuer has agreed to file with the Securities and Exchange Commission a registration statement with respect to the resale of the shares issued pursuant to the Purchase Agreement and any shares issued upon the exercise of the warrant. PEAK6 also has been provided with preemptive rights with respect to certain future offerings of equity securities by the Issuer.

The Purchase Agreement also provides PEAK6 with the right to nominate two designees to the Issuers board of directors, provided that PEAK6 continues to hold the requisite number of Shares as set forth in the Purchase Agreement. The Purchase Agreement requires that the Issuer use its best efforts to ensure that each PEAK6 designee is included on the Issuers director nominee slate and in the Issuers proxy statements for meetings of stockholders of the Issuer called with respect to the election of directors.

Management Services Agreement

In connection with the execution of the Purchase Agreement, the Issuer entered into a management services agreement (the Management Services Agreement) dated as of August 9, 2016, with PEAK6 pursuant to which PEAK6 will provide certain marketing, technology, strategy, development and other services to the Issuer over a five-year period for a cash fee of $1.5 million per year. In addition, in the event PEAK6 partners or employees are engaged to provide marketing or marketing related services to the Issuer either as replacement of Company employees or other external marketing resources engaged by the Issuer or as if they were Company employees, then the Issuer will reimburse PEAK6 for the actual costs incurred of such PEAK6 partners or employees with respect to the marketing or marketing related services so provided to the Issuer; provided, however, that the amount to be reimbursed in any year by the Issuer for such marketing or marketing related services by PEAK6 partners or employees shall not exceed the lesser of Saved Company Marketing Costs or $1,750,000. Saved Company Marketing Costs means the aggregate amount of fully burdened costs to the Issuer of the sales and marketing employees and external marketing resources (consulting or otherwise) that provided marketing or similar services to the Issuer that are replaced or reduced by the Issuer or PEAK6 partners or employees.

In addition, the Issuer appointed Danny Rosenthal as CEO and David Budworth as CTO. Messrs. Rosenthal and Budworth had been employees of PEAK6 prior to their appointment as officers of the Issuer.

As a result of these transactions, PEAK6 is taking a direct and active role in the management, strategy and operations of the Issuer both as a shareholder, through the Issuers board of directors and through the Management Services Agreement.

No Reporting Person has any present plans or proposals which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Subject to the terms of the transaction documents with the Issuer described above and depending on various other factors including, without limitation, the Issuers financial position and strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the board of directors of the Issuer, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including board composition) or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, entering into financial instruments or other agreements that increase or decrease the Reporting Persons economic or beneficial exposure with respect to their investment in the Issuer, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.
