(b)           Call Notice; Call Closing.  During that period beginning on January 1, 2013 and continuing until January 10, 2013 (the “Call Period”), Mr. Kirby, on behalf of the Purchasers, shall deliver to NGL a written notice (the “Call Notice”) specifying (i) the Aggregate Call Price of the Units to be purchased and (ii) the date on which the Call Closing will be consummated (such date to occur no sooner than two (2) Business Days following the delivery of the Call Notice and no later than four (4) Business Days following delivery of the Call Notice) (as so specified, the “Closing Date”).

(c)           Deemed Call.  In the event that Mr. Kirby shall not deliver a Call Notice to NGL prior to January 10, 2013, the parties agree that Mr. Kirby shall be deemed to have submitted a Call Notice on the last day of the Call Period specifying an Aggregate Call Price of Eight Million Dollars ($8,000,000) and a Closing Date of four (4) Business Days thereafter.

(d)           Closing Deliveries.  At 10:00 A.M. local time on the Closing Date, the parties agree to take the following actions:

1.                                      Purchasers shall pay to NGL the aggregate amount of the Aggregate Call Price by wire transfer of immediately available funds; and

2.                                      NGL shall deliver to each Purchaser proof, reasonably acceptable to Mr. Kirby, that such Units have been irrevocably issued in book entry form to the respective Purchaser (or such other Persons as directed by the applicable Purchaser).

No deliveries called for hereby shall be deemed made or effective until such deliveries have been made or waived in writing.

3.             Covenants.  Each Purchaser acknowledges, covenants and agrees that NGL is entering into this Agreement in reliance on (i) the representations and warranties of such Purchaser set forth in the Accredited Investor Questionnaire; and (ii) those certain covenants set forth in Sections 6.7, 6.8 and 6.9 of the Sale Agreement and such representations, warranties and covenants are hereby incorporated herein with the same effect as if originally set forth herein.
