3.11. Exhibit C-1 Amendments:

4.1. Section 1.4(ii) of the Agreement is hereby deleted in its entirety and replaced with the following:

“(ii) If BOWERMAN POWER sells Covered Products to (1) COUNTY, or (2) any other customer at or above the Market Price during that calendar quarter, the royalty for those Covered Products shall be calculated as the greater of either the Minimum Annual Royalty or as follows:

4.2. Section 1.4(v) of the Agreement is hereby deleted and replaced with the following:

“(v) Minimum Annual Royalty: Beginning on the Effective Date of this Third Amendment the annual net minimum royalty (“Minimum Annual Royalty”) payable to COUNTY from Gross Revenue royalties before any offsets up to [***] are deducted for Flare Facility Capital Investment and O&M Expenses will not be less than [***] annually, as long as the annual average Landfill Gas available to the Conversion System and the Flare Facility during any such calendar year is not less than [***] MMBTU/hr (Lower Heating Value).

The Minimum Annual Royalty shall be adjusted annually according to the Cost Index as provided in Section 1.1 of the Agreement.

If the Conversion System ceases operation on any day prior to December 31 in the final year of operation, the minimum annual royalty will be subject to pro rata reduction based on the number of calendar months the Conversion System operated in that calendar year.

After the fourth quarter royalty payment is calculated, the minimum annual royalty due for any given year except the last year of operation of the Conversion System would be the greater of: (1) the royalty as calculated per Section 1.4(i) and 1.4(ii) or (2) the Minimum Annual Royalty amount. The minimum annual royalty payment is due with the fourth quarter payment of each year.

Prepayment of the amount due is allowable. Royalties paid pursuant to the sales of Flare Products as per Section 1.4(iii) are not applicable towards the calculation to meet the Minimum Annual Royalty.

4.3. The following is hereby added to the Agreement as a new Section 1.4(vii):

In any event, prior to (and after) the RNG Commercial Operation Date the Minimum Annual Royalty shall not fall below [***] paid to OCWR annually, as adjusted pursuant to the Cost Index as provided in Section 1.1 of the Agreement.

Any outstanding balance of expenditures made by BOWERMAN POWER for Flare Facility Capital Investment and O&M Expenses or compliance with the Flare Facility Master Plan that may exist upon the expiration of the Term, the Updated Term, or any extension of the Term of this Agreement shall be the sole responsibility of BOWERMAN POWER.”

5.1. Amendment to Section 1.9 (Collection System and Flare Facility). Section 1.9(a) is hereby deleted and replaced with the following:

“(a) Flare Facility Construction. BOWERMAN POWER shall install additional Flares and other Flare Facility components and improvements as reflected in the Flare Facility Master Plan and as may otherwise be required to destruct all Landfill Gas reasonably projected to be recovered by the Collection System at the Landfill and comply with all Applicable Law. The Parties agree that until and alternative method of Landfill Gas destruction and destruction capacity determination is clearly defined in writing by the SCAQMD to the reasonable satisfaction of the Director of OC WASTE & RECYCLING, only Flare Facility capacity will count towards the Landfill Gas destruction capacity requirements required by this Agreement. [***] BOWERMAN POWER agrees to meet at a minimum annually with the COUNTY to review the most current Landfill Gas Generation Rate Table (Exhibit G), and establish a timeline agreed to by both parties as to when expanded Flare capacity is to be installed.

In furtherance of the above, the PARTIES agree that [***]pursuant to the royalty structure agreed to in Section 1.4(ii) of this Third Amendment; provided that (i) [***] shall not be responsible for any material increases to anticipated costs and expenses as set forth in the Flare Facility Master Plan that result from changes to Applicable Law or Policy occurring after the date of this Third Amendment, and any such increases shall be addressed by the Parties in good faith in a subsequent amendment to the Agreement if the existing royalty structure is insufficient to cover the increased costs caused by the changes to Applicable Law, and (ii) [***] hereunder in accordance with Section 1.4(ii). Without limiting the generality of the foregoing, [***]; provided that, when the Temporary H₂S Treatment System is no longer necessary [as mutually determined by the Parties], BOWERMAN POWER shall remove the Temporary H₂S Treatment System, replace it with [straight pipe or similar alternative which ensures continuing compliance with Applicable Law as required under Section 1.15(c) of the Agreement], and [***]. COUNTY shall perform all of its obligations and responsibilities as set forth in the Flare Facility Master Plan and shall otherwise cooperate with BOWERMAN POWER in connection with BOWERMAN POWER’s performance of its obligations hereunder and as provided in the Flare Facility Master Plan. COUNTY agrees to grant to BOWERMAN POWER, and/or to the appropriate utility providers, easements across the Landfill (in form and substance satisfactory to COUNTY in its reasonable discretion) and across property contiguous with the Landfill that is owned or leased by COUNTY and that may be reasonably necessary in connection with BOWERMAN POWER’S exercise of its obligations hereunder. Upon request, COUNTY shall reasonably assist BOWERMAN POWER in connection with obtaining any permits, authorizations or third-party easements with respect to this Third Amendment and as required under the Flare Facility Master Plan.

5.2. Amendments to Section 2.8 (Ownership of Improvements). The following sentence is hereby added to the end of Section 2.8 of the Agreement: [***]

5.3. Basis for Regulatory Compliance. Any changes in Applicable Law that result in new regulatory obligations for the Flare Facility or Capacity that increases the anticipated capital as referenced in the Flare Facility Master Plan may require an amendment to the Agreement to account for additional costs and assignment of responsibilities.
