Seller shall, simultaneously with such delivery pursuant to the preceding sentence, put Purchaser in actual possession and operating control of the Assets. Seller shall also deliver to Purchaser a resolution of the members of Seller (and a resolution of the members of RINA Holdings) specifically approving and ratifying this Agreement, including all terms and conditions hereof and all transactions set forth or contemplated herein.

2.3 Purchase Price. In consideration of the transfer to Purchaser of the Assets, Purchaser shall pay to Seller the Purchase Price, as follows: (a) $4,208,000 in cash on the “Closing Date” (as described and defined below); and (b) $792,000 payable in newly-issued common stock of Parent (the “TS Stock”), on the Closing Date, based upon the average last/closing price of the TS Stock for the 5-day period immediately preceding the Closing Date (i.e., number of shares issued will equal $792,000 divided by the average of said 5-day last/closing price). The Purchase Price shall then simultaneously be distributed by Seller to its members and by RINA Holdings to its members so that ultimately the six (6) individual beneficial owners of Seller receive their proportionate share (a “Member Share”) as follows: (x) ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇ ▇. ▇▇▇▇ shall receive their Member Shares in cash and (y) ▇▇▇▇▇▇▇ ▇. ▇▇▇▇ and ▇▇▇ ▇▇▇▇▇▇▇▇ shall each receive their Member Share eighty percent (80%) in cash and twenty percent (20%) in TS Stock.

Seller has received no notice of deficiency, assessment or collection or proposed deficiency, assessment or collection from any governmental authority which has not been satisfied, nor does Seller have any reason to believe that any such notice will be received in the future.

Further Covenants and Agreements

6.2 Use of Names. Neither Seller nor any of its Affiliates or any of the respective successors and assigns of Seller and such Affiliates shall adopt or otherwise use any Trade Names or Trademarks included in the Assets.

6.3 Certain Covenants of Seller. As an essential inducement to Purchaser to execute and deliver this Agreement and consummate the transactions contemplated hereby, Seller covenants and agrees that it shall from and after the date hereof:

(a) keep secret and retain in the strictest confidence the Confidential Information; provided that, if Seller is required by order of a court or other governmental authority to disclose any Confidential Information, Seller shall immediately notify Purchaser so that Purchaser may attempt to obtain an appropriate protective order, and, in all events, Seller shall only disclose the portion of the Confidential Information required by such order to be disclosed.

(c) not, at any time during the Covenant Period, directly or indirectly persuade or attempt to persuade any customer, supplier or strategic partner or independent contractor of the Business or of Purchaser to not do business or to cease doing business with Purchaser or any Affiliate of Purchaser or to reduce the amount of business it does with Purchaser or any Affiliate of Purchaser; and

(d) not, at any time during the Covenant Period, directly or indirectly, manage, operate, join, control or participate in or obtain any interest in, whether as a partner, joint venturer, stockholder, lender, consultant or otherwise, any business or operation wherever conducted which is in any manner similar to, or competitive with, the Business, or the commercial use of the Software, or otherwise involves, directly or indirectly, the design, development, marketing, sale or other exploitation of trading analysis software, provided, however, that that the foregoing restrictions will not apply to (i) the HedgeFacts products or business including any ownership interest in HedgeFacts, LLP or its Affiliates by Seller’s Affiliates or any agreements between HedgeFacts, LLP or its Affiliates and Seller or any of its Affiliates, (ii) the engagement by Seller and its Affiliates in their proprietary business of trading in the markets (e.g., securities, commodities, currencies, etc.) for their own accounts or the accounts of their clients including the use and development of software for the exclusive use of Seller and its Affiliates and clients in connection with such trading business, or (iii) ownership of less than one percent (1%) of the shares or other equity interests of a publicly traded company.
