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

(v) any invalidity or unenforceability relating to or against Buyer for any reason of this Agreement, the Existing NC Operating Agreement or any provision of applicable law or regulation purporting to prohibit the payment by Buyer of any amounts payable pursuant to the Guarantee; or
(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.
For so long as Buyer fulfills its obligations with respect to the Guarantee, Seller hereby agrees to (i) hold legal ownership of the Northern Comstock Interest, (ii) convey all economic or other benefits associated with the Northern Comstock Interest to Buyer (or Company, at Buyer's election) and (iii) exercise its rights with respect to the Northern Comstock Interest under Existing NC Operating Agreement at Buyer's direction.
(e) The Company owns (or will following the Closing will own) fee property, patented mining claims, and unpatented mining claims, and through the Seller’s membership in Northern Comstock LLC, has indirect ownership of additional fee property, patented mining claims, unpatented mining claims, and leasehold interests, collectively known as the Lucerne project, as detailed in Exhibit A (the “Lucerne Properties”).

Effective as of the Closing Date, Seller shall also agree to lease additional mining properties in Storey County to the Company, in accordance with the lease attached as Exhibit E, (the “Mineral Exploration and Mining Lease”).
(b)  Except as otherwise permitted in this Agreement, Buyer shall not, without the prior written approval of Seller (such approval shall be at Seller's absolute discretion), directly or indirectly, through Company or otherwise, either individually or on behalf of or through any person, for the period commencing on the date of this Agreement  until the day being forty-eight (48) months from the date of this Agreement, in any capacity, (i) locate, stake, lease, option, purchase or otherwise acquire or become entitled to acquire any interest, directly or indirectly, in any property, mineral rights, land rights, surface rights, water rights or other mining-related assets, or (ii) own, manage, stake, control, advise, operate, provide services to, consult with, receive remuneration from, be employed by any person engaged or proposing to engage in, or otherwise engage in any manner in the mining business in any location that is both (i) within five (5) miles of any property currently owned or leased by Seller in Lyon County, Nevada, and (ii) within Lyon County, Nevada (the “Non-Compete Area”).

(d) Until the Note has been repaid in full, Buyer hereby agrees that it will give Seller the first right to directly or indirectly acquire the Membership Interest. Should Buyer determine to directly or indirectly sell or otherwise transfer any part of the Membership Interest (including for the sake of clarity, if Buyer is party to a merger, amalgamation, consolidation transaction (excluding a reverse takeover transaction in which Buyer’s stockholders of record immediately prior to such transaction continue to hold more than 50% of the voting power of the surviving or acquiring entity after such transaction), or substantially all assets or the majority of voting securities of Buyer is acquired by a third party), then Buyer shall give Seller detailed written notice of the nature and description of the proposed transfer and its intended price and terms. Seller shall have a period of 30 days to investigate the proposed transaction and the disposition terms (for which Buyer shall grant full access to all records and data to Seller) and Seller shall have a period of 30 days after such investigative period to determine whether it will acquire the Membership Interest. In the event Seller declines then Buyer may sell at such offered terms but this first right shall occur again to the benefit of Seller if the terms shall be reduced or if the disposition does not occur within 180 days of Buyer’s notice it declines or the expiration of the above 30 day decision period.
(e) Buyer hereby agrees to pay in full all existing or future invoices issued by Seller on or prior to the due dates indicated on such invoices, it being agreed and understood that that reimbursement payments will be prioritized and the Buyer shall wire funds received by Buyer from any source to Seller within 24 hours of receipt, for such expense reimbursement obligations.
(f) Comstock hereby consents to the Buyer’s acquisition of certain mining claims, royalties and properties described in Exhibit I (the “Ida Properties”) which are owned by Art Wilson, Wilson Mining LLC, Ida Consolidated Mines, Southern Comstock Tailings Disposal, Art Wilson Co (together the “Wilson Parties”), and waives the restrictions of Section 1.3 (b) for the portion of the Ida Properties in the Non-Compete Area. This consent is conditioned on (i) Buyer assigning to Comstock the patented and unpatented mining claims along the State Route to the south of Silver City and West of Spring Valley, further identified in Exhibit I, Table I.2, for no additional consideration, concurrently with the acquisition of the Ida Area Claims from the Wilson Parties; (ii) the Ida Area Claims will be subject to the NSR Royalty Agreement shown in Exhibit B; and (iii) Buyer assigning to Comstock any royalty interests owned by the Wilson Parties on the Metropolitan patent and Peach and Wedge unpatented claims, a portion of Comstock’s Dayton property package and identified in Exhibit I, Table I.3. Comstock undertakes to use reasonable commercial efforts to make introductions to assist Buyer in attempting to acquire other patents in close proximity to the Three Brothers, including the Last Chance, Piedmont, Twin, and Cosmopolitan patents, if such patents are available for purchase.
(g) Buyer will reimburse the additional cost of interest incurred by Comstock under the Debenture for the entire period from May 31, 2019 until such time as the Note is paid in full (the “Incremental Interest”). Estimates for each month’s Incremental Interest will be itemized with each monthly invoice for reimbursed expenses from Comstock.
(h) Seller has entered into a collaborative venture with Oro Industries Inc., and a newly formed company called Mercury Clean Up LLC (“MCU”), for the manufacture and global deployment of mercury remediation systems with proprietary mechanical, hydro, electro-chemical and oxidation processes to reclaim, treat and remediate mercury from tailings and industrial effluents. Seller has agreed to allow MCU and its affiliates, including future joint ventures formed for the purpose of mercury remediation (e.g., MCU and Comstock Mercury Remediation LLC) to conduct certain testing to demonstrate the feasibility of a mercury remediation system within the historic, world-class, Comstock Lode mining district. Buyer hereby agrees to permit Seller and MCU to sample the soils and/or tailings, including taking bulk samples for pilot testing, and extracting and processing the mercury contaminated materials from the properties owned or controlled by the Buyer, so long as such activities are not likely to interfere, with either current or future operations of the Buyer (to be determined at the sole discretion of the Buyer but not to be unreasonably withheld), or reduce the value of the Buyer’s assets in any way (it is mutually understood that the objective and net effect of these remediation activities is the identification of mercury contamination from these properties and the removal of such contaminated material). Seller and MCU expect mineralized materials removed by MCU to contain limited amounts of precious metals, the recoveries of which are intended to mitigate the overall investment and costs of removal and Seller will be responsible for any and all costs and obligations associated with removal by MCU, including royalties, if any, on precious metals recovered. Neither Seller nor MCU will penetrate bedrock or dislocate any virgin, mineralized materials. Seller agrees to maintain adequate insurance coverage to specifically protect Buyer from any damages or costs resulting from the activities of Seller or MCU. Seller and MCU will comply with all legal and regulatory requirements on the properties. Seller agrees to provide Buyer with a detailed plan of MCU’s proposed work programs and schedules in advance of conducting remediation activities.
