(Coordinates 39.719097 / -80.186217)?on the H-508 pipeline must be shut in by 7:00 AM on March 26, 2024 and remain shut in for the duration
of the pig run, which has an estimated duration of 10 hours.?

Next, People’s Natural Gas Delivery/Receipt Meters between Lumberport M&R Station (Coordinates 39.390668 / -80.345552) and Blacksville
Compressor Station (Coordinates 39.719097 / -80.186217)?on the H-508 pipeline may experience higher than normal pressures during the
March 27, 2024, geometry, and smart pig run, which has an estimated duration of 10 hours. ?If Customers and/or Customers’ suppliers or
operators elect not to shut-in their equipment, Customer shall be liable for any damages resulting from the aforementioned pig runs.

Lastly, Customer Receipt Meter: #24577 (Statler IC) must be shut in by 7:00 AM ET on March 26, 2024, and March 27, 2024, and remain shut in

damages including, but not limited to, direct, consequential, exemplary, or punitive damages incurred by Equitrans or any other party as a result
of such failure, (2) a penalty of $25 per Dth times the quantity of gas by which the Customer deviated from the requirements of this OFO, (3) flow
control, and/or (4) a reduction in scheduled quantities to match flowing gas. In addition, Equitrans will not permit post-cycle adjustments to avoid
