i. Swing PDA: One of the Commingled Shippers at a Commingled Point is designated as the “swing.” All other Shippers are allocated their respective Scheduled Quantities. The Shipper identified as “swing” is allocated the remaining difference between the Measured Quantity and quantities allocated to non-swing Shippers. The swing Shipper is not permitted to be allocated a quantity which would result in a negative number, therefore any negative quantity will be allocated to the non-swing Shippers on a pro-rata basis in accordance with the Scheduled Quantities. A separate agreement may also be designated as “swing” under this allocation method.

ii.Ranked PDA: This allocation methodology is applicable to a Commingled Shipper with multiple contracts at a Point. Each of such multiple contracts may be assigned a rank and the allocated quantity to such Commingled Shipper at such point is further allocated to a contract with the lowest rank value among the multiple contracts before the next sequentially higher-ranked contract.

iii.Percentage PDA: This allocation methodology is applicable to a Commingled Shipper with multiple contracts at a Point. Each such multiple contracts may be assigned a percentage value and the allocated quantity to such Commingled Shipper at such point is allocated to each such contract by multiplying allocated quantity by the respective percentage.

b)In the absence of mutually agreed Allocation methodology as per the Section 3.11 a) above, the Initial Allocation of Gas, in respect of any Gas Flow Day at a Delivery Point where Commingled Shippers deliver Gas (a “Shared Delivery Point”) shall be made in accordance with the formula set out below:

AQ Delivery= MQDelivery x SQDelivery / ASQDelivery

Where: AQDelivery -The Allocated Quantity of Gas, in MMBTU, allocated to a Shipper at the Shared Delivery Point;

MQDelivery -The Measured Quantity of Gas, in MMBTU, at the Shared Delivery Point

SQDelivery- The Shipper’s Scheduled Quantity of Gas, in MMBTU, at the Shared Delivery Point;

ASQDelivery -The aggregate of Scheduled Quantities in MMBTU, for all the Shippers at the Shared Delivery Point

c) At a Delivery Point that is not a Shared Delivery Point, Measured Quantity of Gas shall be allocated to the Shipper delivering Gas at that Point. Such allocation shall be the Initial Allocation and the Final Allocation.

3.12 Allocation at a Redelivery Point:

a) Transporter and the Commingled Shippers may mutually agree in writing for Allocation methodology for a Shared Redelivery Point in which case such mutually agreed Allocation methodology shall prevail. Allocation methodologies may include the following:

i. Swing PDA: One of the Commingled Shippers at a Commingled Point is designated as the “swing.” All other Shippers are allocated their respective Scheduled Quantities. The Shipper identified as “swing” is allocated the remaining difference between the Measured Quantity and quantities allocated to non-swing Shippers. The swing Shipper is not permitted to be allocated a quantity which would result in a negative number, therefore any negative quantity will be allocated to the non-swing Shippers on a pro-rata basis. in accordance with the Scheduled Quantities. A separate agreement may also be designated as “swing” under this allocation method.

ii.Ranked PDA: This allocation methodology is applicable to a Commingled Shipper with multiple contracts at a Point. Each of such multiple contracts may be assigned a rank and the allocated quantity to such Commingled Shipper at such point is further allocated to a contract with the lowest rank value among the multiple contracts before the next sequentially higher-ranked contract.

iii.Percentage PDA: This allocation methodology is applicable to a Commingled Shipper with multiple contracts at a Point. Each such multiple contracts may be assigned a percentage value and the allocated quantity to such Commingled Shipper at such point is allocated to each such contract by multiplying allocated quantity by the respective percentage.

b)In the absence of mutually agreed Allocation methodology as per the Section 3.11 a) above, the Initial Allocation of Gas, in respect of any Gas Flow Day at a Redelivery Point where Commingled Shippers offtake Gas (a “Shared Redelivery Point”) shall be made in accordance with the formula set out below:

AQRedelivery=MQRedeliveryx SQRedelivery/ASQRedelivery

Where: AQRedelivery – The Allocated Quantity of Gas Allocated in MMBTU to a Shipper at the Shared Redelivery Point ;

MQRedelivery – The Measured Quantity of Gas in MMBTU at the Shared Redelivery Point;

SQRedelivery – The Shipper’s Scheduled Quantity in MMBTU at the Shared Redelivery Point;

ASQRedelivery – The aggregate Scheduled Quantities in MMBTU for all the Shippers at the Shared Redelivery Point

c)At a Redelivery Point that is not a Shared Redelivery Point, Measured Quantity of Gas shall be allocated to the Shipper delivering Gas at that Point. Such allocation shall be the Initial Allocation and the Final Allocation.

3.13 Change to the Initial Allocation:

(a) At a Point Shipper(s) may agree on a different Allocation from the Initial Allocation as between themselves, of their aggregate Allocated Quantity of Gas for any Day (a “Reallocation”).

(b)A Reallocation shall be requested:

i.by all affected Shippers writing jointly to Transporter;

ii.only during the period between 1600 hours. of D+1 and 1000 hours on D+2; and

d) Without limiting the Transporter’s available remedies, if any of the Shipper fails to comply, or fails to cause its operator to comply, with any Operational Flow Orders issued by the Transporter in accordance with this Section 5, then Transporter may charge such defaulting Shipper, the Unauthorised Overrun Charge and/or Imbalance Charge under its respective GTA, for each MMBTU of Gas by which the defaulting Shipper deviates from the Operational Flow Order, if such Shipper has delivered or offtaken more Gas than that was specified in the Operational Flow Order.

e) The Transporter shall not be liable for any failure to deliver Gas or comply with any of its obligations to a Shipper under this Section 5 that are caused by or can be attributable to the failure of such Shipper to take actions in accordance with Operational Flow Order issued by Transporter.

f) Where the Transporter believes that the quantity or the rate of Gas being off taken by any of the Shipper exceeds the quantity or the rate of Gas expected to be off taken by such Shipper in accordance with the Operational Flow Order issued by the Transporter, the Transporter shall have the right to take steps to reduce the rate of offtake of Gas by the defaulting Shipper or discontinue the offtake of Gas by the defaulting Shipper from the Redelivery Point.

g) The Shipper shall be liable to pay for the Transmission Charges for the quantities delivered and off taken as per the Operational Flow Order.

5.5 Emergency:

(a) An Emergency may exist:

i. by reason of leakage, or suspected leakage, of Gas; or

ii. in circumstances which, in the opinion of the Transporter, acting as RPO:

1) the safety of the Transporter Facilities is at risk;

2) the safe conveyance of Gas by the Transporter Facilities is at risk,

3) Gas conveyed by the Transporter Facilities is at such pressure or of such a quality as to constitute when supplied to premises, a danger to life or property; or

4) any other circumstances reasonably believed by the Transporter to constitute an Emergency (which, for the avoidance of doubt, may include circumstances upstream of a Delivery Point), and, where the context requires a reference to an Emergency includes the event or circumstance which gives rise to such Emergency.

(b) In particular, but without limitation, an Emergency may exist where the Transporter’s ability to maintain safe pressures within the Transporter Facilities is affected or threatened by an interruption or disruption to the Transporter Facilities or by, an insufficiency of deliveries of Gas to other Party’s Facilities, or by any actual or potential failure of or damage to any part of the Transporter Facilities or any other act or omissions of the Shipper which gives rise to any of the situations enlisted in this sub-Section (b).

(c) An Emergency will continue until such time as the Transporter determines that the circumstances referred to in this Section 5.5 no longer apply, that no further Emergency steps are required, and that normal operation of the Transporter Facilities may be resumed.

(d) The Transporter as an RPO shall take steps to restore transmission of Gas and normal operation of the Transporter Facilities with reasonable diligence and efforts considering the most appropriate and predictable outcome, after an Emergency.

5.6 Interruptions: Subject to the limitations of Section 5.7, the Transporter shall after as much notice to the Shipper as is reasonably possible be permitted to curtail deliveries of Gas without incurring liabilities to the Shipper, for such periods of time as it may reasonably be required for the purpose of effecting any emergency repairs, maintenance, replacement or upgrading or other works related to the Transmission System for reasons arising out of compliance with directives of Government Agency, for reason of safety and to avoid environmental pollution. The need for shut off will be determined and executed by the Transporter acting as RPO.

5.7 Limitations:

a) Notwithstanding any provision of this Code, the GTA, or the CT Agreement to the contrary, the Parties agree that, for purposes of determining Shortfall Quantity under the GTA, circumstances, where the Transporter is excused pursuant to this Section 5, shall be limited to a cumulative period not to exceed 168 hours in any Contract Year, nor to exceed three times during such period of 168 Hours in any Contract Year or as specified in the relevant CT Agreement. For this purpose, it is clarified that circumstances, where Transporter is excused on account of Force Majeure or Planned Works or as a result of Shipper’s breach of its obligations under the CT Agreement or non-compliance with this Operating Code, shall not be subject to or included in such limit.

b) For the avoidance of doubt, nothing contained in this Section 5 shall excuse Transporter in respect of curtailment or interruptions due to safety or environmental concerns if such interruption/curtailment has arisen as a result of the Transporter not acting as a Reasonable and Prudent Operator.

6) Overrun, Deviation & Balancing

6.1 Authorized Overruns Quantities:

(a) The Shipper’s Authorised Overrun Quantity at each Redelivery Point measured in MMBTU, on a Day shall be calculated as follows:

i) For each Redelivery Point, if the Allocated Quantity at the Redelivery Point >= Scheduled Quantity at the Redelivery Point > CT Redelivery Point MDQ, then the Authorised Overrun Quantity shall be the excess of the Scheduled Quantity at the Redelivery Point over the CT Redelivery Point MDQ; and

ii) For each Redelivery Point, if the Scheduled Quantity at the Redelivery Point > Allocated Quantity at the Redelivery Point > CT Redelivery Point MDQ, then the Authorised Overrun Quantity shall be the excess of the Allocated Quantity at the Redelivery Point over the CT Redelivery Point MDQ.

(b) If the Transporter has agreed to transmit the excess quantity of Gas requested by the Shipper then the Transporter shall make reasonable endeavors to transmit and deliver the Authorised Overrun Quantity in addition to the CT Redelivery Point MDQ for that Day. Any such service provided by the Transporter shall be an “Authorised Overrun Service”. However, if the Transporter has received but fails to redeliver the Authorized Overrun Quantity, no Liquidated Damages shall be payable to the Shipper but Transporter shall be obligated to redeliver to Shipper the quantity received from Shipper at the Delivery Point.

(c) Unless expressly agreed by the Transporter in writing, consent of the Transporter to transmit and deliver Gas in excess of the CT Redelivery Point MDQ shall not in any manner whatsoever be construed as an agreement to transmit and deliver Gas in excess of the MDR in any hour on any other Day other than a Day for which the Transporter has agreed to transport the Authorised Overrun Quantity.

6.2 Unauthorized Overruns Quantities:

a) The Shipper’s Unauthorised Overrun Quantity at a Redelivery Point measured in MMBTU, on a Day shall be calculated as follows:

For Ship or Pay CTAs –

i. if Allocated Quantity at the Redelivery Point > CTRedelivery Point MDQ Scheduled Quantity at the Redelivery Point, then the Unauthorised Overrun Quantity shall be the excess of the Allocated Quantity at the Redelivery Point over the CT Redelivery Point MDQ;

ii. if Allocated Quantity at the Redelivery Point > Scheduled Quantity at the Redelivery Point > CT Redelivery Point MDQ, then the Unauthorised Overrun Quantity shall be the excess of the Allocated Quantity at the Redelivery Point over the Scheduled Quantity at the Redelivery Point; and

iii. If there is no such excess, the Unauthorised Overrun Quantity shall be zero.

iv. Notwithstanding the foregoing on a Constraint Day, Unauthorised Overrun Quantity shall be equal to Allocated Quantity at Redelivery Point on such Day minus quantity of Gas scheduled for the Shipper as specified in the relevant Operational Flow Order issued as per Section 5.2.

6.3 Imbalance Quantities:

(a) Transporter shall determine Shipper’s Imbalance Quantities in respect of each Day in accordance with this Section 6.4.

(b) Shipper’s “Positive Imbalance Quantity” on a Day shall be the excess of the aggregate of Shipper’s Allocated Quantities at all Delivery Points over the aggregate of Shipper’s Allocated Quantities at all Redelivery Points in each case. If there is no such excess then the Positive Imbalance Quantity shall be zero.

(c) Shipper’s “Negative Imbalance Quantity” on a Day shall be the excess of the aggregate of Shipper’s Allocated Quantities at all Redelivery Points over the aggregate of Shipper’s Allocated Quantities at all Delivery Points in each case. If there is no such excess then the Negative Imbalance Quantity shall be zero.

(d) The “Imbalance Quantities” on a Day shall mean the Positive Imbalance Quantity or the Negative Imbalance Quantity, as applicable, on that Day.

6.4 Cumulative Imbalance

a) The Transporter shall determine the difference between the quantity of Shipper’s Gas within the Transporter Facilities (“Cumulative Imbalance”) at the start and end of each Day in accordance with this Section.

b) The Cumulative Imbalance at the start of a Day shall be equal to the Cumulative Imbalance at the end of the previous Day.

c) At the start of the first day when Gas is transported, the Cumulative Imbalance shall be zero.

d) The Cumulative Imbalance at the end of a Day shall equal to Cumulative Imbalance at the start of the Day plus Positive Imbalance Quantity for the Day or minus Negative Imbalance Quantity for the Day, whichever is applicable.

e) The Cumulative Imbalance shall be measured in SCM and MMBTU and may be either positive or negative and shall be called Cumulative Positive Imbalance or Cumulative Negative Imbalance respectively.

If the Shipper fails to maintain the Cumulative Imbalance within 10% percent of the sum of the CT Delivery Point MDQ on positive side and 5% percent of the sum of the CT Delivery Point MDQ on the negative side and the Shipper does not correct the same, then the Transporter shall have the right to adjust the nominations of the Shipper at Delivery Point and Redelivery Point as the case may be to maintain the imbalances within such operational limits. If as a result of such adjustment Transporter is unable to meet its pressure obligations under Section 8, the Transporter shall not be liable for any resulting Shortfall Quantity if any Pressure Notice is served by the Shipper.

6.5 Balancing:

a) On each day the Shipper shall be responsible to control and, if necessary, adjust nominations, receipt and deliveries of Gas, to maintain a balance between Gas delivered and received. Any adjustment to receipts and deliveries by Shipper, whether or not pursuant to notification from Transporter, shall be coordinated with Transporter and shall be done only with the consent of the Transporter and accomplished in accordance with the procedures for Nomination and Scheduling set forth in the Operating Code.

b) On each Day, the Transporter shall be entitled, with the consent of the Shipper, which shall not be unreasonably withheld to control and, if necessary, adjust, Shipper’s scheduled receipts and deliveries of Gas, to maintain a balance over a Day between Gas received and delivered upon failure by the Shipper to do so in order to minimize Cumulative Imbalance

c) In respect of any Imbalance Quantities which may occur, the Shipper and Transporter will cooperate to minimize any Imbalance Quantities taking into consideration the time period allowed for cure on any upstream or downstream entities delivering Gas to, or receiving Gas from the Transporter as the case may be and the Shipper shall make daily adjustments in nominations, receipts and/or deliveries, as the case may be.

d) Transporter shall always have the right in accordance with Section 10 to amend the provisions related to Balancing Quantities in the Transporter Facilities in order to ensure that the Transporter Facilities is operated in the most efficient manner. The Transporter shall have the right to take any action including rescheduling that may be required (including suspension or reduction of service to the Shipper) to correct any Imbalances which impair or threaten the operational integrity of the Pipeline or the maintenance of Transportation Service to other Shippers. The Transporter shall not be liable in any manner for any loss, costs, and expenses incurred by the Shipper due to any such action of the Transporter.

6.6 Correction of Imbalance quantities on Other Systems:

The Transporter shall not be responsible or liable in any manner for any imbalance arising out of any trading of capacity arrangement (including any swap arrangement) between the Shipper and any third party. The Transporter shall not be obliged to adjust or deviate from its standard operating and accounting procedures in order to alleviate any such imbalances. Any swap arrangement between the Shipper and any third party shall be subject to allocation systems being in place.

6.7 Correction of Imbalances at the End of a fortnight:

Shipper shall bring Cumulative Imbalance to within operational limits at the end of each fortnight. If any Imbalance as communicated by the Transporter to the Shipper is not cured by the Shipper at the end of each fortnight, then the Transporter shall have unilateral right to adjust the nominations at Delivery and Redelivery points as the case may be, without any liability, to maintain the imbalances with in operational limits as mentioned in Section 6.4.

6.8 Reconciliation

At the expiry or early termination of the relevant CT Agreement, the Parties shall reconcile the total quantities of Gas delivered by the Shipper at the relevant CT Delivery Point with the total quantities of Gas redelivered by the Transporter at the relevant CT Redelivery Point. If upon such reconciliation, it is found that the Shipper has off taken quantities of Gas less than what was delivered by the Shipper at such CT Delivery Point, the Transporter shall redeliver equal quantities of Gas to the Shipper within 3 (three) Days of expiry or early Termination of the relevant CT Agreement and the Shipper shall make arrangement for such redelivery of Gas. If upon such reconciliation, it is found that the Transporter has under any CT Agreement redelivered at the relevant CT Redelivery Point quantity of Gas more than what was delivered by the Shipper at the relevant CT Delivery Point, then the Shipper shall deliver equal quantities of Gas to the Transporter within 3 (three) Days of the expiry or early Termination of the relevant CT Agreement. If Transporter redelivers Gas to Shipper on expiry or early termination of the relevant CT Agreement in accordance with this Section 6.8, Shipper shall pay the tariff in effect at the end of the term, plus applicable Taxes, on such quantities provided that if the Shipper incurred an Monthly Ship-or-Pay Payment for the period ending on the expiry or termination of the relevant CT Agreement, Shipper shall pay the tariff only on such quantities that exceed the quantity on which the Monthly Ship-or-Pay Payment is based.

6.9 Reconciliation beyond 3 days:

a) If the Shipper has off-taken quantities of Gas less than what was delivered by the Shipper at such CT Delivery Point which was not cured within 3 (three) days after the expiry or early Termination of the relevant CT Agreement then following provisions shall be applicable:

i)The less quantity of gas off taken from the pipeline in the expired CT shall be the opening balance of another CT to be executed within a period of 3(three) days for the same Delivery and Redelivery points.

ii)After a period of 3 (three) days, Transporter shall have the right to purchase such quantities of gas from Shipper at Delivery Point at the rate of lowest-priced gas in the pipeline system plus all the applicable taxes at Delivery Point of transport pipeline. The lowest-priced gas in the pipeline system shall be informed by the Transporter from time to time.

b) If the Shipper has off taken a quantity of Gas more than what was delivered by the Shipper at the relevant CT Delivery Point which was not cured within 3 (three) days of the expiry or early Termination of the relevant CT Agreement then following provisions shall be applicable:

i) The Shipper shall first make up for the additional quantity of gas off taken from the pipeline, under a new CT or the quantity of gas off taken more under the expired CT shall be the opening balance of another CT executed within a period of 3 (three) days for same Delivery and Redelivery Point.

ii)If the imbalance is not cured beyond 3 (three) Days then after a period of 3 Days, Shipper will have to buy such gas from the Transporter at Redelivery Point at the rate 120% of the highest-priced gas in the pipeline system plus transmission charges and all the applicable taxes and charges at Redelivery Point. The highest-priced gas in the pipeline system shall be informed by the Transporter from time to time.

c) In case of Shipper is ready to cure the imbalance within a period of 3 days and Transporter is unable to provide the gas transmission services during that period then the Transporter shall exclude the number of Days for which the services could not be offered by the Transporter from the calculations at Clause 6.9 (a) and Clause 6.9 (b) above.

7) Pressure

7.1 Acceptable Pressure Ranges: For each Point there shall be an Acceptable Pressure Range, as specifically provided in the CT Agreement.

7.2 Pressure at Delivery Point: The Shipper shall ensure that Gas shall be delivered to Transporter at the Delivery Point at pressures sufficient to allow the Gas to enter the Transporter Facilities, within the Acceptable Pressure Range set out in the relevant CT Agreement.

7.3 If the Shipper has failed to comply with the obligations prescribed in Section 7.2 above; the Transporter shall have the right to refuse to take delivery of Gas at the Delivery Point. Such refusal to take deliveries of Gas at the Delivery Point shall not be construed as a failure of the Transporter in performing its obligations under the GTA and no Shortfall Quantities shall be applicable. The Shipper may, however, be obligated to pay Transmission Charges as determined in accordance with the GTA.

7.4 Difference in Pressure at Delivery Point:

a) High Pressure at Delivery Point:

In the event that Shipper is delivering Gas at the Delivery Point and the pressure at the Delivery Point has increased beyond the Acceptable Pressure Range for such Delivery Point but the rate of flow at the Delivery Point is below that set down in the Daily Scheduling Statement and is not rising, then Shipper may serve a Pressure Notice to the Transporter in accordance with the Section 7.8.

b) Low Pressure at Delivery Point

i. If the Gas, which Shipper makes available at the Delivery Point, falls to a pressure below the Acceptable Pressure Range then Transporter shall use reasonable endeavors to transmit that Gas and Transporter may issue a revised Daily Scheduling Statement reflecting its revised expectations on Gas flows and Imbalance Charges may become due but there shall be no Shortfall Quantity.

ii. Transporter shall not have any specific remedy if the pressure at Delivery Point falls below the Acceptable Pressure Range other than the remedies stated under Section 7.3.

7.5 Pressure at the Redelivery Point:

a) Transporter shall deliver Gas for Shipper’s account at the pressures existing from time to time in Transporters Facilities at the Redelivery Point(s) that may vary within the Acceptable Pressure Range for such Redelivery Point.

b) The Transporter may reduce the pressure for offtake from that specified in Section 7.5 a) down to not less than minimum pressure of the Acceptable Pressure Range for any reason.

c) Subject to Section 7.5d, the Transporter shall be relieved of its obligations under Section 7.5 a), if, in order to maintain sufficient pressure in its transmission system to continue operation, it would be necessary to reduce or switch-off totally the quantities to be delivered at one or more Redelivery Point(s) under the condition that (a) the quantities to be off taken are greater than quantities scheduled at Redelivery Point or are to be subjected to Operational Flow Orders as per Section 5.2 or are in excess of the quantities actually supplied at corresponding Delivery Point and (b) the operation of the system is duly endangered for providing Transmission Services under normal conditions and causes attributable to Shipper.

d) The relief referred to in Section 7.5 c) shall only be available to the Transporter if it has used reasonable endeavors to maintain the pressure specified in Section 7.5 a).

7.6 Low Pressure at the Redelivery Point:

a)Where the Gas, which Transporter makes available for offtake at the Redelivery Point, falls to a pressure below the Acceptable Pressure Range then Shipper shall use reasonable endeavors to continue to accept such Gas. In such circumstances, Shipper may serve a Pressure Notice on Transporter in accordance with Section 7.8 provided that the low pressure is not attributable to

i.Shipper not delivering the Scheduled Gas Flows at the Delivery Point; or

ii.The pressure at the upstream of the Delivery Point having fallen below the Acceptable Pressure Range; or

iii. Shipper having a Cumulative Negative Imbalance Quantity in excess of five percent (5%) on the Day in question;

7.7 High Pressure at the Redelivery Points If the pressure at the Redelivery Point rises above the Acceptable Pressure Range and the Shipper does not have a Cumulative Positive Imbalance Quantity in excess of ten percent (10%) of the Delivery Point MDQ on that Day, then Shipper may serve a Pressure Notice on the Transporter in accordance with the Section 7.8. Shortfall Quantities may arise from this breach.

7.8 Pressure Notice:

a)In accordance with Section 7.4 a) and 7.6 and 7.7, Shipper may serve a “Pressure Notice” on Transporter where Transporter fails to maintain the Transporter Facilities within the Acceptable Pressure Range and the same is causing the Shipper to breach its obligations under this Agreement.

b)A Pressure Notice shall state that Shipper will no longer accept any Imbalance Charges because of unacceptable pressures in the Transporter Facilities. It shall also specify

i.The Delivery Point or Redelivery Point in question;

ii.The current pressure at the Point;

iii.The Acceptable Pressure Range for the Point;

iv.The current flow rate at the Point; and

v. The flow rate at the Point required by the most recent Daily Scheduling Statement for the Day.

c) If Shipper serves a Pressure Notice on Transporter then Shipper shall not be liable for any Imbalance Charges under the GTA for the period between the Pressure Notice being received by Transporter and a revised Daily Scheduling Statement being received by Shipper, however, Shortfall Quantities shall also become applicable in accordance with the provisions of the GTA.

8) Quality

8.1 Gas Quality Tests:

a) There shall be arrangements, in accordance with this Section 8.1 for determining whether or not the Gas meets the Specification as specified in Annexure 2 of GTA

8.9 If the Gas offered for delivery by Transporter at the Redelivery Point fail at any time to conform to the Specifications in accordance with Annexure 2 of GTA, then Shipper shall have a right to reject all or any portion of such Gas, which has failed to conform to the specifications set forth herein. At any time after the Shipper has accepted or is deemed to have accepted any Off-Spec Gas in accordance with Section 8.8 c), Shipper may, at its election, subsequently reject further quantities of Off-Spec Gas with immediate effect upon providing written notice of such election to the Transporter. The acceptance, or deemed acceptance, of any Off-Spec Gas by the Shipper at the Redelivery Point in accordance with the provisions of this Section 8.9 shall not be construed as an agreement or consent by the Shipper to accept any Off-Spec Gas at any Redelivery Point at any future point in time.

8.10 If the Shipper refuses to accept Gas tendered by Transporter at the Redelivery Point because such Gas does not conform to Specifications in accordance with the Annexure 2 of GTA and it is not due to the failure of Shipper in tendering Gas at the Delivery Point conforming to Specifications in accordance with the Annexure 2 of GTA, then Shipper shall not be liable for payment of Transmission Charges to the extent of the Off-Spec Gas quantities. Any Imbalance Charge arising due to this on such Day shall not be payable. Further, Shortfall Quantities shall also arise as per the provisions of GTA.

8.11 However Shipper shall have no rights under Section 8.10 if Transporter’s failure to tender Gas meeting the Specification in accordance with Annexure 2 of GTA at Redelivery Point is a consequence of Shipper tendering Gas at the Delivery Point, which does not conform to the Specification in accordance with Annexure 2 of GTA unless such Gas was accepted by Transporter in accordance with this Section 8.

8.12 Without prejudice to any other remedies expressly set out in the GTA or this Code, the sole remedies that the Party has against the other Party for delivery of Off Specs Gas in breach of this Section 8 shall be those stated in the Section 8.6 only.
