Anchor shippers may enjoy benefits such as contract extension rights, limited capacity proration exposure, favorable cost sharing terms, potential early service for certain portions of capacity, negotiated fixed rates and other benefits on a not-unduly discriminatory basis. Project Timing The Project is anticipated to be available for commercial service as early as November 1, 2029, subject to timing of precedent agreement(s) execution, regulatory approvals and permits, which is the earliest date that will be considered for the purpose of net present value (“NPV”) calculations.  Contract Term  The minimum required contract term is twenty (20) years, and TCO reserves the right to reject any bids that include a contract term of less than twenty (20) years.  Length of Open Season  This Open Season will commence at 11:00 AM CST on November 13, 2025 and close at 12:00 PM CDT on January 9, 2026. Participation in the Open Season To participate in this Open Season, interested parties desiring firm transportation capacity in the Project shall complete an Open Season Request Form (attached), with specific attention to the primary term of service, service commencement date, firm capacity requested, rate for service (as set forth herein) and desired receipt and delivery point combination prior to 12:00 PM CDT on January 9, 2026.After the close of this Open Season, TCO will follow-up with interested parties submitting a bid to determine next steps with respect to allocation of Project capacity and execution of a binding precedent agreement(s) for further development of the Project. TCO reserves the right to immediately negotiate and enter into binding precedent agreements with parties that participate in this Open Season and may or may not elect to hold any further open seasons related to the Project, including any binding open seasons.  Priority will be given to those shippers’ bids with the highest overall economic value to the Project, as determined by TCO on a non-discriminatory basis.  It is anticipated that binding precedent agreements will be executed with interested parties on or before March 31, 2026.

TCO will evaluate individual bids based on the total impact on and optimization of Project economics and/or operational viability as determined by TCO in its sole discretion on a not unduly discriminatory basis.  TCO reserves the right to reject and remove from consideration non-conforming bids, bids that have a delayed in-service requirement or other contingencies, bids that require a contract with a partial-year term, or fail to meet the minimum terms set forth above with regards to rate, contract term, or any other economic criteria which could adversely affect the optimization of the economics or operational viability of the Project.  TCO reserves the right to define and maintain the economic viability of the Project at all times in its sole discretion, and TCO retains the right to enter into negotiations during this Open Season with those parties who express interest in the Project. After evaluating all valid acceptable bids, TCO will initially award Project capacity as follows:·         Capacity awards will be made first to bidders who qualify as anchor shippers·         If capacity remains after awarding to anchor shippers, then any remaining capacity will be awarded to acceptable bid(s) providing the next highest NPV, with the awarded capacity pro-rated in the event the requested capacity exceeds remaining available capacity.  If the NPVs of separate bids are equal, then available capacity will be allocated pro-rata based on the capacity bid.  The process will be repeated until no additional valid acceptable bid remains without an associated award, or the entire anticipated Project capacity has been awarded.Interested parties are responsible for securing their own transportation arrangements on pipelines upstream and downstream of the designated receipt and delivery points. These procedures and the attached Request Form are provided solely to enable interested parties to participate and attempt to obtain capacity in the proposed Project.  TCO’s decision to proceed with the proposed Project is subject to receiving a level of binding precedent agreements, that in its sole discretion, TCO determines to be acceptableMoreover, TCO explicitly reserves the right to (1) conduct additional open seasons/reverse open seasons; (2) determine or re-determine the size, scope, and cost of the Project; (3) clarify bids; and/or (4) reject or accept bids and/or material it receives after the close of this Open Season on a not unduly discriminatory basis. Solicitation of Turnback Capacity Existing shippers who currently hold firm transportation capacity on the TCO system and who believe such capacity could be used in lieu of a portion(s) of the proposed Project are invited to notify TCO, through the attached Request Form, of their desire to permanently relinquish their capacity for use in the Project. Such turnback requests must be received by TCO by the close of this Open Season. This solicitation of turnback capacity is not binding on TCO.  Turnback requests are subject to rejection or proration by TCO on a not unduly discriminatory basis for any reason, including but not limited to TCO’s evaluation of the results of this Open Season, and/or their failure to be compatible, be economically accretive, or directly offset the Project’s incremental facilities that TCO proposes to construct and/or modify to satisfy the Project’s capacity. Contact Information Interested parties should contact the following TCO personnel to discuss any questions or to seek additional information about this Open Season: Andrew IsherwoodDirector, Business Development832-320-5903 (office)713-828-4609 (cell)andrew_isherwood@tcenergy.com For Creditworthiness Requirements:Usman KhanBusiness Analyst Transportation Accounting & Contracts832-320-5418 (office)281-889-9435 (cell)usman_khan@tcenergy.com Columbus Area ProjectNon-Binding Open Season Request Form (Page 1)   Please return this Service Request Form by email on or before the dates listed below. Reverse Open Season                                       Project Open SeasonJanuary 9, 2026 (before 12:00 PM CDT)          January 9, 2026 (before 12:00 PM CDT) To:   [ ] (Please include the phrase “Columbus Area Project Request Form” in the subject line) Request for (Check One):
