FINDINGS OF FACT

11.

The Purchaser is Bunker Hill Mining Corp., formerly Liberty Silver Corporation.

12.

The Mine is currently owned by Placer Mining Corporation (“PMC”).

13.

On August 17, 2017, the Purchaser and PMC entered into a Mining Lease with Option to Purchase (“Lease”). The Lease became effective December 1, 2017 and the term of the Lease is two years from the effective date. The Lease provides that the Purchaser will operate the Bunker Hill Mine and make certain improvements on the Mine along with making payments to PMC over the term of the Lease. Pursuant to the Lease, the Purchaser has the exclusive right to purchase the Bunker Hill Mine during the lease term upon notice to PMC and the United States. Consummation of the purchase of the Mine is conditioned on, among other things, reaching agreement with the United States regarding potential environmental liabilities arising from the purchase of the Mine. The Lease is attached as Appendix 1 hereto.

14.

Purchaser intends to increase operations and increase the number of individuals employed at the Mine. This increase in employment would not occur absent the Lease and purchase of the Mine by the Purchaser.

15.

The Mine is located south of Kellogg, in the Silver Valley of Shoshone County, Idaho within the Bunker Hill Mining and Metallurgical Superfund Site (the “Site”). The Site includes residential communities, industrial areas, and non-populated areas.

16.

Environmental contamination of surface water, groundwater, soil, and sediment occurred at the Site as a result of mining, milling, and smelting operations in the Silver Valley, including but not limited to, at the Bunker Hill Mining and Metallurgical Complex (“Complex”), of which the Mine was a part. Operations at the Complex started in 1885 and continued through the 1980s, and included an integrated system of mining, milling, and smelting. Prior to 1928, liquid and solid waste from the Complex was discharged directly into the South Fork of the Coeur d’Alene River and its tributaries. Following 1928, waste from the Complex was directed to a nearby floodplain where a Central Impoundment Area (“CIA”) was developed. Acid mine drainage (“AMD”) and wastewater from the Complex were discharged to a settling pond in the CIA. In 1974, a Central Treatment Plant (“CTP”) was built by the Bunker Hill Mining Company, the owner and operator of the Complex at the time. AMD and wastewater from the Complex were stored in an unlined pond in the CIA before being decanted to the CTP. In 1981, following the closure of the smelter, the CIA was no longer required to impound wastewater from the Complex, although surface runoff from the Complex and AMD from the Mine were still routed to the CIA prior to treatment at the CTP. Sludge which formed during the treatment process was also disposed in unlined ponds at the CIA.

17.

Ownership of the Complex passed through a number of companies throughout the 100-year operation of the Complex. In early 1991, the Bunker Limited Partnership, then owner of the Complex and operator of the CTP, closed the Mine and filed for bankruptcy. In late 1991 and 1992, PMC purchased a portion of the Site, which includes underground workings, mineral rights, and much of the land surface above the Mine, from Bunker Limited Partnership. PMC did not purchase the entire Complex nor the CTP. In November 1994, federal and State governments assumed operation of the CTP for ongoing treatment of AMD.

18.

AMD is a result of acid-forming reactions occurring within the Mine among water, oxygen, sulfide minerals (especially pyrite), and bacteria. AMD is acidic with typical pH levels between 2.5 and 3.5, and it contains high levels of dissolved and suspended heavy metals. For human receptors, the constituents of primary concern at the Site found in the AMD are arsenic, cadmium, lead, mercury, and thallium, and for aquatic and terrestrial receptors they are aluminum, arsenic, cadmium, copper, iron, lead, manganese, mercury, selenium, silver, and zinc. Impacts on human health from exposure to these constituents include carcinogenic effects, skin lesions, neuropathy, gastrointestinal irritation, kidney damage, interference with metabolism, and interference with the normal functioning of the central nervous system. Impacts on the environment from exposure to these constituents include significant mortality of fish and invertebrate species, elevated concentrations of metals in the tissues of fish, invertebrates, and plants, and reduced growth and reproduction of aquatic life.

19.

AMD is generated and discharged from the Mine continuously. AMD from the Mine is drained through the ▇▇▇▇▇▇▇ Tunnel portal and then passes through a conveyance system to the CTP for treatment. Average AMD discharge from the Mine during typical flow periods is approximately 1300 gallons per minute. During high flow periods AMD may be diverted to a lined surface impoundment on the Site, where it mixes with other minimal wastewater streams from the Mine. From the impoundment, it is pumped to the CTP for treatment. If not collected and treated at the CTP, AMD from the Mine would flow downhill through the mine yard, across properties where public and environmental exposures would occur, and into Bunker Creek and the South Fork Coeur d’Alene River where it would have significant detrimental effects on water quality and the ecosystem.

20.

Initially, the Bunker Hill Superfund Site was divided into two operable units, the Populated Areas and the Non-Populated Areas, in order to focus investigation and cleanup efforts. A Record of Decision (“ROD”) for the Non-Populated Areas Operable Unit was signed on September 22, 1992. A ROD Amendment for the Non-Populated Areas Operable Unit, addressing the management of AMD was issued in December 2001. A third operable unit was created to address contamination in the Coeur d’Alene Basin, and a ROD for Operable Unit 3, the Coeur d’Alene Basin, was issued in 2002.

21.

In 1994, EPA issued a unilateral administrative order (“UAO”) to PMC directing PMC to keep the mine pool pumped to an elevation below the level of the South Fork Coeur d’Alene River (at or below Level 11 of the Mine) to prevent discharges to the river, to convey mine water to the CTP for treatment unless an alternative form of treatment was approved, and to provide for emergency mine water storage within the mine. In 2017, EPA issued a UAO to PMC directing PMC to control mine water flows to the CTP during needed upgrades at the CTP and in high flow periods, to conduct operation and maintenance of the ▇▇▇▇ Landing Flood Control

Project, to file an environmental covenant on a portion of the Mine property regarding access and operation and maintenance, and allowing PMC to fill the mine pool to Level 10 during diversion events.

22.

Response actions required by the 1994 and 2017 UAOs are currently being performed by PMC. Upon the later of the Effective Date of this Settlement Agreement or the Consent Decree resolving the United States’ pending CERCLA claims against PMC and the Estate of ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇., EPA will withdraw the 1994 and 2017 UAOs. To the extent that aspects of those UAOs require ongoing work, ▇▇▇▇▇▇▇▇▇ agrees to perform such work when Purchaser becomes the operator of the Mine, and to continue to perform such work when Purchaser becomes the owner upon subsequent purchase of the Mine. Ongoing work requirements are described in detail in Section IX (Work to be Performed) below.

VI.

DETERMINATIONS

23.

Based on the Findings of Fact set forth above, and the Administrative Record supporting this removal action, EPA has determined that:

The Mine is a “facility” as defined by Section 101(9) of CERCLA, 42 U.S.C. § 9601(9).

The contaminants found at and released from the Mine, as identified in the Findings of Fact above, include “hazardous substances” as defined by Section 101(14) of CERCLA, 42 U.S.C. § 9601(14).

Purchaser is a “person” as defined by Section 101(21) of CERCLA, 42 U.S.C. § 9601(21).

The conditions described in Paragraphs 18-19 of the Findings of Fact above constitute an actual or threatened “release” of a hazardous substance from the facility as defined by Section 101(22) of CERCLA, 42 U.S.C. § 9601(22).

The Work is necessary to protect the public health, welfare, or the environment and, if carried out in compliance with the terms of this Settlement Agreement, will be considered consistent with the NCP, as provided in Section 300.700(c)(3)(ii) of the NCP.

VII.

Potential Alteration of Payment Schedule. The Parties acknowledge that circumstances may arise necessitating alteration of the payment schedule set forth in Paragraph 38 above. The Parties address here those circumstances that are reasonably foreseeable to them at this time:

If Purchaser cancels or defaults on the lease, or the lease terminates for any reason other than expiration of the lease term (or any extended lease term) or Purchaser’s purchase of the Mine:

Purchaser shall pay any amounts due pursuant to Paragraph 38, above, and shall pay in full any outstanding payment due for water treatment pursuant to Paragraph 39 up through the month in which the lease terminates. Water treatment costs shall be calculated using the monthly rate of $80,000 and further reconciled with actual costs;

If Purchaser extends the lease term:

Purchaser shall make payments as they come due pursuant to Paragraph 38, above, and shall continue to make payments for water treatment in accordance with Paragraph 39;

If Purchaser purchases the Mine and transfers all or substantially all of its interest in the Mine prior to completing the entire schedule of payments referenced in Paragraph 38:

The payment schedule in Paragraph 38 shall be accelerated and all payments thereunder shall be due and payable to the United States effective upon such transfer and the United States shall be deemed to have a security interest in any consideration given for such transfer;

ii.

Purchaser shall pay in full any outstanding payment due for water treatment up through the month of the transfer. Water treatment costs shall be calculated using the monthly rate of $80,000 and further reconciled with actual costs;

iii.

To the extent that consideration for such transfer realized by Purchaser exceeds Purchaser’s documented investment in the Mine plus 10% of that investment, the United States is entitled to an 80% share of such excess until the United States has been reimbursed all of its $24 million past costs incurred at the Mine plus interest as provided by 42 U.S.C. § 9607;

iv.

Such transfer must be conditioned upon Transferee reaching agreement with the United States regarding ongoing responsibility for water treatment costs;

If Purchaser purchases the Mine and files for bankruptcy or ceases operating at the Mine at any time prior to completing the payments required in Paragraph 38:

The United States shall be deemed a secured creditor of Purchaser to the extent of all payments required under Paragraph 38 and not remitted at the petition date and all payments due under Paragraph 39.

If Purchaser fails to make a payment as set forth in the payment schedules of Paragraphs 38 or 39, Purchaser shall have a three-month period in which to cure such default, which shall include Interest (as defined above) during the period of nonpayment.

XI.

ACCESS/NOTICE TO SUCCESSORS/INSTITUTIONAL CONTROLS

44.

Purchaser agrees to provide EPA, its authorized officers, employees, representatives, and all other persons performing response actions under EPA oversight, an irrevocable right of access at all reasonable times to the Mine and to any other property owned or controlled by Purchaser to which access is required for the implementation of response actions at the Site. EPA agrees to provide reasonable notice to Purchaser of the timing of response actions to be undertaken at the Mine and other areas owned or controlled by Purchaser. Notwithstanding any provision of this Settlement Agreement, the United States retains all of its access authorities

and rights, including enforcement authorities related thereto, under CERCLA, RCRA, and other authorities.

In particular, Purchaser shall not obstruct access to a pipeline maintenance port in the Mine yard area. Access to this port is required for routine maintenance, including but not limited to pipeline pigging, conducted by the CTP operators to ensure flows can reliably be conveyed to the CTP for treatment. The location is marked as “Upper Pigging/Camera Access Vault and Gate Valve” on the map included as Appendix 5.

45.

Purchaser shall submit to EPA for review and approval a notice to be filed with the Recorder’s Office or other appropriate office, Shoshone County, State of Idaho, which shall provide notice to all successors-in-title that the Mine is part of the Site, and that EPA issued a Record of Decision in 1992 and a Record of Decision Amendment in 2001 providing for the performance of a remedial action at the Site. Purchaser shall record the notice within 15 days of EPA’s approval of the notice. Purchaser shall provide EPA with a certified copy of the recorded notice within 7 days of recording such notice.

46.

Purchaser shall implement and comply with any land use restrictions and institutional controls on the Mine.

47.

For so long as Purchaser is an owner or operator of the Mine, Purchaser shall require that assignees, successors in interest, and any lessees, sublessees and other parties with rights to use the Mine shall provide access and cooperation to EPA, its authorized officers, employees, representatives, and all other persons performing response actions under EPA oversight. Purchaser shall require that assignees, successors in interest, and any lessees, sublessees, and other parties with rights to use the Mine implement and comply with any land use restrictions and institutional controls on the Mine, and not contest EPA’s authority to enforce any such land use restrictions and institutional controls on the Mine.

48.

Upon sale or other conveyance of the Mine or any part thereof, Purchaser shall require that each grantee, transferee or other holder of an interest in the Mine or any part thereof shall provide access and cooperation to EPA, its authorized officers, employees, representatives, and all other persons performing response actions under EPA oversight. Purchaser shall require that each grantee, transferee or other holder of an interest in the Mine or any part thereof shall implement and comply with any land use restrictions and institutional controls on the Mine in connection with a response action and not contest EPA’s authority to enforce any such land use restrictions and institutional controls on the Mine.

49.

Purchaser shall provide a copy of this Settlement Agreement to any current lessee, sublessee, and other party with rights to use the Mine as of the Effective Date.

XII.

INSURANCE

50.

Not later than 15 days before commencing any Work to be Performed on-site under this Settlement Agreement, Purchaser shall secure, and shall maintain, commercial general liability insurance with limits of two million dollars, for any one occurrence, naming the United States as an additional insured with respect to all liability arising out of the activities performed

by or on behalf of Purchaser pursuant to this Settlement Agreement. In addition, for the duration of the Settlement Agreement, Purchaser shall satisfy, or shall ensure that its contractors or subcontractors satisfy, all applicable laws and regulations regarding the provision of worker’s compensation insurance for all persons performing the Work to be Performed on behalf of Purchaser in furtherance of this Settlement Agreement. Within the same time period, Purchaser shall provide EPA with certificates of such insurance and a copy of each insurance policy. Purchaser shall submit such certificate and copies of policies each year on the anniversary of the Effective Date. If Purchaser demonstrates by evidence satisfactory to EPA that any contractor or subcontractor maintains insurance equivalent to that described above, or insurance covering some or all of the same risks but in an equal or lesser amount, then, with respect to that contractor or subcontractor, Purchaser needs provide only that portion of the insurance described above that is not maintained by the contractor or subcontractor.

XIII.

RECORD RETENTION, DOCUMENTATION, AND AVAILABILITY OF INFORMATION

51.

Purchaser shall preserve all documents and information in its possession relating to the Work, or relating to the hazardous substances, pollutants or contaminants found on or released from the Mine, and shall submit them to EPA upon completion of the Work required by this Settlement Agreement, or earlier if requested by EPA.

52.

Business Confidential Claims. Purchaser may assert that all or part of a Record provided to EPA pursuant to this Settlement Agreement is business confidential to the extent permitted by and in accordance with Section 104(e)(7) of CERCLA, 42 U.S.C. § 9604(e)(7), and 40 C.F.R. § 2.203(b). Purchaser shall segregate and clearly identify all Records or parts thereof submitted under this Settlement Agreement for which Purchaser asserts business confidentiality claims. Records claimed as confidential business information will be afforded the protection specified in 40 C.F.R. Part 2, Subpart B. If no claim of confidentiality accompanies Records when they are submitted to EPA, or if EPA has notified Purchaser that the Records are not confidential under the standards of Section 104(e)(7) of CERCLA or 40 C.F.R. Part 2, Subpart B, the public may be given access to such Records without further notice to Purchaser.

XIV.

DISPUTE RESOLUTION

53.

The dispute resolution procedures of this Section shall be the exclusive mechanism for resolving disputes arising under this Settlement Agreement. The United States and Purchaser shall attempt to resolve any disagreements concerning this Settlement Agreement expeditiously and informally. If the United States contends that Purchaser is in violation of this Settlement Agreement, the United States shall notify Purchaser in writing, setting forth the basis for its position. Purchaser may dispute the United States’ position pursuant to Paragraph 54.

54.

If Purchaser disputes the United States’ position with respect to Purchaser’s compliance with this Settlement Agreement or objects to any United States action taken pursuant to this Settlement Agreement, Purchaser shall notify EPA in writing of its position unless the dispute has been resolved informally. The United States may reply, in writing, to Purchaser’s position within 30 days of receipt of Purchaser’s notice. The United States and Purchaser shall have 20 days from EPA’s receipt of Purchaser’s written statement of position to resolve the

dispute through formal negotiations (the “Negotiation Period”). The Negotiation Period may be extended by agreement of the parties. Such extension must be confirmed in writing.

55.

Any agreement reached by the Parties pursuant to this Section shall be in writing and shall, upon signature by both Parties, be incorporated into and become an enforceable part of this Settlement Agreement. If the Parties are unable to reach an agreement within the Negotiation Period, an EPA management official in the Region 10 Office of Environmental Cleanup at or above the level of Unit Manager will review the dispute on the basis of the Parties’ written statements of position and issue a written decision on the dispute. That written decision shall be incorporated into and become an enforceable part of this Settlement Agreement. Purchaser’s obligations under this Settlement Agreement shall not be tolled by submission of any objection for dispute resolution under this Section. Following resolution of the dispute, as provided by this Section, Purchaser shall fulfill the requirement that was the subject of the dispute in accordance with the agreement reached or with the written decision, whichever occurs.

XV.

CERTIFICATION

56.

By entering into this Settlement Agreement, Purchaser certifies that to the best of its knowledge and belief it has fully and accurately disclosed to the United States all information known to Purchaser and all information in the possession or control of its officers, directors, employees, contractors and agents which relates in any way to any Existing Contamination or any past or potential future release of hazardous substances, pollutants or contaminants at or from the Site and to its qualification for this Settlement Agreement. Purchaser also certifies that to the best of its knowledge and belief it has not caused or contributed to a release or threat of release of hazardous substances or pollutants or contaminants at the Site. If the United States determines that information provided by Purchaser is not materially accurate and complete, this Settlement Agreement, within the sole discretion of the United States, shall be null and void and EPA reserves all rights it may have.

XVI.

WORK TAKEOVER

57.

In the event EPA determines that Purchaser: (1) has ceased implementation of any portion of the Work to be Performed; (2) is seriously or repeatedly deficient or late in its performance of the Work to be Performed; or (3) is implementing the Work to be Performed in a manner that may cause an endangerment to human health or the environment, EPA may issue a written notice (“Work Takeover Notice”), which may be electronic, to Purchaser. Any Work Takeover Notice issued by EPA will specify the grounds upon which such notice was issued and will provide Purchaser a period of 3 days within which to remedy the circumstances giving rise to EPA’s issuance of such notice.

58.

If, after expiration of the 3-day notice period specified in Paragraph 57, Purchaser has not remedied to EPA’s satisfaction the circumstances giving rise to EPA’s issuance of the relevant Work Takeover Notice, EPA may at any time thereafter assume the performance of all or any portion(s) of the Work to be Performed as EPA deems necessary (“Work Takeover”). EPA will notify Purchaser in writing, which may be electronic, if EPA determines that implementation of a Work Takeover is warranted under this Paragraph.

59.

Notwithstanding any other provision of this Settlement, EPA retains all authority and reserves all rights to take any and all response actions authorized by law.

XVII.

COVENANT NOT TO SUE BY UNITED STATES

60.

Except as provided in Section XVIII (Reservation of Rights by the United States) and in consideration of the actions that will be performed in Section IX and the payments that will be made by Purchaser, pursuant to Paragraph 39, under the terms of this Settlement Agreement, the United States covenants not to sue or to take administrative action against Purchaser pursuant to Sections 106 and 107(a) of CERCLA, 42 U.S.C. §§ 9606 and 9607(a), for Existing Contamination, Work, and payments made pursuant to Paragraph 39. This covenant not to sue shall take effect upon the Effective Date and is conditioned upon the complete and satisfactory performance by Purchaser of all obligations under this Settlement Agreement coming due during Purchaser’s leasehold, ownership, and/or occupancy of the Mine, including, but not limited to, performance of the Work required by this Settlement Agreement and the payments required pursuant to Paragraph 39. This covenant not to sue extends only to Purchaser and does not extend to any other person. In no event shall Purchaser’s liability for Existing Contamination exceed the amount owed by Purchaser pursuant to Paragraphs 38 and 39.

XVIII.

RESERVATION OF RIGHTS BY UNITED STATES

61.

Except as specifically provided in this Settlement Agreement, nothing herein shall limit the power and authority of EPA or the United States to take, direct, or order all actions necessary to protect public health, welfare, or the environment or to prevent, ▇▇▇▇▇, or minimize an actual or threatened release of hazardous substances, pollutants or contaminants, or hazardous or solid waste on, at, or from the Site. Further, nothing herein shall prevent the United States from seeking legal or equitable relief to enforce the terms of this Settlement Agreement, or from taking other legal or equitable action as it deems appropriate and necessary.

62.

The covenant not to sue set forth in Section XVII, above, does not pertain to any matters other than those expressly identified therein. The United States reserves, and this Settlement Agreement is without prejudice to, all rights against Purchaser with respect to all other matters, including, but not limited to:

liability for failure by Purchaser to meet a requirement of this Settlement Agreement;

criminal liability;

liability for damages for injury to, destruction of, or loss of natural resources, and for the costs of any natural resource damage assessments;

liability for violations of federal, state, or local law or regulations during or after implementation of the Work other than as provided in the Workplan, the Work, or otherwise ordered by EPA;

liability resulting from the release or threat of release of hazardous substances, pollutants or contaminants at or in connection with the Site after the Effective Date, not within the definition of Existing Contamination;

liability resulting from exacerbation of Existing Contamination by Purchaser, its agents, contractors, sub-contractors, successors, assigns, lessees, or sublessees;

liability arising from Purchaser’s, its agents’, or its employees’ disposal, release or threat of release of Waste Materials outside of the Site.

63.

With respect to any claim or cause of action asserted by the United States, Purchaser shall bear the burden of proving that the claim or cause of action, or any part thereof, is attributable solely to Existing Contamination and that Purchaser has complied with all of the requirements of 42 U.S.C. § 9601(40).

XIX.

COVENANT NOT TO SUE BY PURCHASER

64.

Purchaser covenants not to sue and agrees not to assert any claims or causes of action against the United States, or its contractors or employees, with respect to Existing Contamination, the Work, payments pursuant to Paragraph 39, or this Settlement Agreement, including, but not limited to:

any direct or indirect claim for reimbursement from the EPA Hazardous Substance Superfund established by 26 U.S.C. § 9507, based on Sections 106(b)(2), 107, 111, 112, or 113 of CERCLA, 42 U.S.C. §§ 9606(b)(2), 9607, 9611, 9612, or 9613, or any other provision of law;

any claim arising out of response actions, including any claim under the United States Constitution, the ▇▇▇▇▇▇ Act, 28 U.S.C. § 1491, the Equal Access to Justice Act, 28 U.S.C. § 2412, or at common law; or

any claim pursuant to Sections 107 and 113 of CERCLA, 42 U.S.C. §§ 9607 and 9613, Section 7002(a) of RCRA, 42 U.S.C. § 6972(a), or state law.

65.

Purchaser reserves, and this Settlement Agreement is without prejudice to, claims against the United States, subject to the provisions of Chapter 171 of Title 28 of the United States Code, and brought pursuant to any statute other than CERCLA or RCRA and for which the waiver of sovereign immunity is found in a statute other than CERCLA or RCRA, for money damages for injury or loss of property or personal injury or death caused by the negligent or wrongful act or omission of any employee of the United States, as that term is defined in 28 U.S.C. § 2671, while acting within the scope of his or her office or employment under circumstances where the United States, if a private person, would be liable to the claimant in

accordance with the law of the place where the act or omission occurred. However, the foregoing shall not include any claim based on EPA’s selection of response actions, or the oversight or approval, disapproval, or modification of Purchaser’s plans, reports, other deliverables, or activities.

66.

Nothing in this Settlement Agreement shall be deemed to constitute approval or preauthorization of a claim within the meaning of Section 111 of CERCLA, 42 U.S.C. § 9611, or 40 C.F.R. § 300.700(d).

XX.

EFFECT OF SETTLEMENT/CONTRIBUTION

67.

Nothing in this Settlement Agreement precludes the United States or Purchaser from asserting any claims, causes of action, or demands for indemnification, contribution, or cost recovery against any person not a party to this Settlement Agreement. Nothing herein diminishes the right of the United States, pursuant to Sections 113(f)(2) and (3) of CERCLA, 42 U.S.C. § 9613(f)(2) and (3), to pursue any such persons to obtain additional response costs or response actions and to enter into settlements that give rise to contribution protection pursuant to Section 113(f)(2).

68.

If a suit or claim for contribution is brought against Purchaser, the Parties agree that this Settlement Agreement shall then constitute an administrative settlement pursuant to which Purchaser has, as of the Effective Date, resolved liability to the United States within the meaning of Sections 113(f)(2) of CERCLA, 42 U.S.C. § 9613(f)(2), and is entitled, as of the Effective Date, to protection from contribution actions or claims as provided by Sections 113(f)(2) of CERCLA, or as may be otherwise provided by law, for the “matters addressed” in this Settlement Agreement. The “matters addressed” in this Settlement Agreement are the Work to be Performed and payments made pursuant to Paragraph 39.

69.

The Parties agree that this Settlement Agreement shall constitute an administrative settlement pursuant to which Purchaser has, as of the Effective Date, resolved liability to the United States within the meaning of Section 113(f)(3)(B) of CERCLA, 42 U.S.C. § 9613(f)(3)(B).

70.

▇▇▇▇▇▇▇▇▇ agrees that with respect to any suit or claim brought by it for matters related to this Settlement Agreement it will notify the United States in writing no later than 60 days prior to the initiation of such suit or claim.

71.

▇▇▇▇▇▇▇▇▇ also agrees that with respect to any suit or claim for contribution brought against it for matters related to this Settlement Agreement it will notify the United States in writing within 10 days of service of the complaint on it. In addition, ▇▇▇▇▇▇▇▇▇ agrees that it will notify the United States within 10 days of service or receipt of any Motion for Summary Judgment and within 10 days of receipt of any order from a court setting a case for trial, for matters related to this Settlement Agreement.

XXI.

RELEASE AND WAIVER OF LIENS

72.

Subject to the Reservation of Rights in Section XVIII of this Settlement Agreement, and so long as Purchaser is in compliance with the requirements of Sections IX

(Work to be Performed) and X (Payment), EPA agrees not to enforce any lien it may have on the Mine, and upon satisfactory completion of the Payments specified in Section X, Paragraph 38, EPA agrees to release and waive any lien it may have on the Mine now and in the future under Section 107(r) of CERCLA, 42 U.S.C.§ 9607(r), for costs incurred or to be incurred by EPA in responding to the release or threat of release of Existing Contamination.

XXII.

INDEMNIFICATION

73.

Purchaser shall indemnify, save, and hold harmless the United States, its officials, agents, contractors, subcontractors, employees, and representatives from any and all claims or causes of action arising from, or on account of, negligent or other wrongful acts or omissions of Purchaser, its officers, directors, employees, agents, contractors, or subcontractors, in carrying out actions pursuant to this Settlement Agreement. In addition, ▇▇▇▇▇▇▇▇▇ agrees to pay the United States all costs incurred by the United States, including but not limited to attorneys’ fees and other expenses of litigation, arising from or on account of claims made against the United States based on negligent or other wrongful acts or omissions of Purchaser, Purchaser’s officers, directors, employees, agents, contractors, subcontractors, and any persons acting on Purchaser’s behalf or under Purchaser’s control, in carrying out activities pursuant to this Settlement Agreement. The United States shall not be held out as a party to any contract entered into by or on behalf of Purchaser in carrying out activities pursuant to this Settlement Agreement. Neither Purchaser nor any such contractor shall be considered an agent of the United States.

74.

The United States shall give Purchaser notice of any claim for which the United States plans to seek indemnification pursuant to this Section and shall consult with Purchaser prior to settling such claim.

75.

Purchaser waives all claims against the United States for damages or reimbursement or for set-off of any payments made or to be made to the United States, arising from or on account of any contract, agreement, or arrangement between Purchaser and any person for performance of Work on or relating to the Site, including, but not limited to, claims on account of construction delays. In addition, Purchaser shall indemnify and hold harmless the United States with respect to any and all claims for damages or reimbursement arising from or on account of any contract, agreement, or arrangement between Purchaser and any person for performance of Work on or relating to the Site, including, but not limited to, claims on account of construction delays.
