(b) In addition, on the Closing Date, if permitted, Seller will assign all of its interest (the ” Northern Comstock Interest “) in Northern Comstock LLC, a Nevada limited liability company (“ Northern Comstock “) to the Company. If such assignment is not approved by the members and manager of Northern Comstock on or prior to Closing, then Buyer hereby agrees to forever assume and unconditionally guarantee the full and punctual payment, fulfilment and performance of all obligations and benefits of Seller under the current Northern Comstock LLC Operating Agreement (the “ Existing NC Operating Agreement ”).

Without limiting the generality of the foregoing, the Guarantee shall not be released, discharged or otherwise affected by:

(ii) any modification or amendment of or supplement to the Existing NC Operating Agreement;

(vi) any other act or omission to act or delay of any kind by Buyer, the Company, Seller, Northern Comstock or any other person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to Buyer’s obligations pursuant to the Guarantee.
