The Separation

SECTION 2.01. Transfer of Assets and Assumption of Liabilities. (a) Prior to the Distribution, and subject to Section 2.01(e), the Parties shall cause the Internal Transactions to be completed.

(b) Subject to Section 2.01(e), immediately after the Internal Distribution and prior to the Distribution, the Parties shall, and shall cause their respective Group members to, execute such instruments of assignment or transfer, and take such other corporate actions as are necessary to:

(i) assign, transfer or convey to one or more members of the DT Midstream Group all of the right, title and interest of the DTE Energy Group in, to and under all DT Midstream Assets not already owned by the DT Midstream Group;

(ii) assign, transfer or convey to one or more members of the DTE Energy Group all of the right, title and interest of the DT Midstream Group in, to and under all DTE Energy Assets not already owned by the DTE Energy Group;

(iii) cause one or more members of the DT Midstream Group to assume all of the DT Midstream Liabilities to the extent such Liabilities would otherwise remain obligations of any member of the DTE Energy Group; and

(iv) cause one or more members of the DTE Energy Group to assume all of the DTE Energy Liabilities to the extent such Liabilities would otherwise remain obligations of any member of the DT Midstream Group.

Notwithstanding anything to the contrary, neither Party shall be required to transfer any Information except as required by Article VII.

(c) In the event that it is discovered after the Distribution that there was an omission of (i) the transfer or conveyance by DT Midstream (or a member of the DT Midstream Group) to, or the acceptance or assumption by, DTE Energy (or a member of the DTE Energy Group) of any DTE Energy Asset or DTE Energy Liability, as the case may be, (ii) the transfer or conveyance by DTE Energy (or a member of the DTE Energy Group) to, or the acceptance or assumption by, DT Midstream (or a member of the DT Midstream Group) of any DT Midstream

Asset or DT Midstream Liability, as the case may be, or (iii) the transfer or conveyance by one Party (or any other member of its Group) to, or the acceptance or assumption by, the other Party (or any other member of its Group) of any Asset or Liability, as the case may be, that, had the Parties given specific consideration to such Asset or Liability prior to the Distribution, would have otherwise been so transferred, conveyed, accepted or assumed, as the case may be, pursuant to this Agreement or the Ancillary Agreements, the Parties shall, subject to Section 2.01(e), use reasonable best efforts to effect such transfer, conveyance, acceptance or assumption of such Asset or Liability, as the case may be, as promptly as reasonably practicable. Any transfer, conveyance, acceptance or assumption made pursuant to this Section 2.01(c) shall be treated by the Parties for all purposes as if it had occurred immediately prior to the Distribution, except as otherwise required by applicable Law or a Final Determination.

(d) In the event that it is discovered after the Distribution that there was a transfer or conveyance (i) by DT Midstream (or a member of the DT Midstream Group) to, or the acceptance or assumption by, DTE Energy (or a member of the DTE Energy Group) of any DT Midstream Asset or DT Midstream Liability, as the case may be, or (ii) by DTE Energy (or a member of the DTE Energy Group) to, or the acceptance or assumption by, DT Midstream (or a member of the DT Midstream Group) of any DTE Energy Asset or DTE Energy Liability, as the case may be, the Parties shall, subject to Section 2.01(e), use reasonable best efforts to transfer or convey such Asset or Liability back to the transferring or conveying Party or to rescind any acceptance or assumption of such Asset or Liability, as the case may be, as promptly as reasonably practicable. Any transfer or conveyance made or acceptance or assumption rescinded pursuant to this Section 2.01(d) shall be treated by the Parties for all purposes as if such Asset or Liability had never been originally transferred, conveyed, accepted or assumed, as the case may be, except as otherwise required by applicable Law or a Final Determination.

(e) To the extent that any transfer or conveyance of any Asset (other than Shared Contracts, which are governed solely by Section 2.04) or acceptance or assumption of any Liability (other than Shared Contracts, which are governed solely by Section 2.04) required by this Agreement to be so transferred, conveyed, accepted or assumed, as the case may be, shall not have been completed prior to the Distribution, the Parties shall use reasonable best efforts to effect such transfer, conveyance, acceptance or assumption, as the case may be, as promptly as reasonably practicable following the Distribution. Nothing in this Agreement shall be deemed to require the transfer or conveyance of any Assets or the acceptance or assumption of any Liabilities which by their respective terms (or the terms of any Contract relating to such Asset or Liability) or operation of Law cannot be so transferred, conveyed, accepted or assumed; provided, however, that, prior to and following the Distribution, the Parties shall use reasonable best efforts to obtain and make any necessary Governmental Approvals and other Consents for the transfer, conveyance, acceptance or assumption (as applicable) of all Assets and Liabilities required by this Agreement to be so transferred, conveyed, accepted or assumed; provided further that neither Party nor any member of its Group shall be required to contribute capital, pay or grant any consideration or concession in any form (including providing any letter of credit, guaranty or other financial accommodation) to any Person in order to obtain or make any such Consent (other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be reimbursed by the Party or the member of the Party’s Group entitled to such Asset or intended to assume such Liability, as applicable, as promptly as reasonably practicable). In the event that any such transfer, conveyance, acceptance or assumption (as

applicable) has not been completed effective as of the Distribution, the Party retaining such Asset or Liability (or the member of the Party’s Group retaining such Asset or Liability) shall thereafter hold such Asset for the use and benefit, and at the expense, of the Party to which such Asset should have been transferred or conveyed pursuant to this Agreement and retain such Liability for the account, and at the expense, of the Party by which such Liability should have been assumed or accepted pursuant to this Agreement, and take such other actions as may be reasonably requested by the Party or the member of its Group to which such Asset should have been transferred or conveyed, or by which such Liability should have been assumed or accepted, as the case may be, in order to place such Party or the member of its Group, insofar as reasonably possible without violation of any contractual obligations to third parties, in the same position as it would have been had such Asset or Liability been transferred, conveyed, accepted or assumed (as applicable) as contemplated by this Agreement and so that the benefits and burdens relating to such Asset or Liability, as the case may be, including possession, use, risk of loss, potential for gain/loss and control over such Asset or Liability, as the case may be, are to inure from and after the Distribution to such Party or the member of its Group. As and when any such Asset or Liability becomes transferable or assumable, as the case may be, the Parties shall, and shall cause the members of its Group to, use reasonable best efforts to effect such transfer, conveyance, acceptance or assumption (as applicable) as promptly as reasonably practicable.

(f) The Party retaining any Asset or Liability due to the deferral of the transfer and conveyance of such Asset or the deferral of the acceptance and assumption of such Liability pursuant to this Section 2.01 or otherwise shall not be obligated by this Agreement, in connection with this Section 2.01, to expend any money or take any action that would require the expenditure of money (other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be reimbursed by the Party or the member of the Party’s Group to which such Asset should have been transferred or conveyed pursuant to this Agreement or by which such Liability should have been assumed or accepted pursuant to this Agreement, as applicable, as promptly as reasonably practicable) unless and to the extent the Party or the member of the Party’s Group entitled to receive such Asset or intended to assume such Liability, as applicable, advances or agrees to reimburse it for the applicable expenditures. For the avoidance of doubt, reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees shall not include any purchase price, license fee or other payment or compensation for the procurement of any asset intended to replace an Asset in the course of a Party’s obligation under Section 2.01(e).

(g) DT Midstream hereby waives compliance by each and every member of the DTE Energy Group with the requirements and provisions of any “bulk-sale” or “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the transfer or sale of any or all of the DT Midstream Assets to any member of the DT Midstream Group.

(h) DTE Energy hereby waives compliance by each and every member of the DT Midstream Group with the requirements and provisions of any “bulk-sale” or “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the transfer or sale of any or all of the DTE Energy Assets to any member of the DTE Energy Group.

(i) In the event that DTE Energy determines to seek novation with respect to any DT Midstream Liability, DT Midstream shall reasonably cooperate with, and shall cause the

members of the DT Midstream Group to reasonably cooperate with, DTE Energy and the members of the DTE Energy Group (including, where necessary, entering into appropriate instruments of assumption and, where necessary, DT Midstream providing parent guarantees in support of the obligations to the extent assumed pursuant to such instruments of assumption by other members of the DT Midstream Group) to cause such novation to be obtained, on terms reasonably acceptable to DT Midstream, and to have DTE Energy and the members of the DTE Energy Group released from all liability to third parties arising after the date of such novation and, in the event DT Midstream determines to seek novation with respect to any DTE Energy Liability, DTE Energy shall reasonably cooperate with, and shall cause the members of the DTE Energy Group to reasonably cooperate with, DT Midstream and the members of the DT Midstream Group (including, where necessary, entering into appropriate instruments of assumption and, where necessary, DTE Energy providing parent guarantees in support of the obligations to the extent assumed pursuant to such instruments of assumption by other members of the DTE Energy Group) to cause such novation to be obtained, on terms reasonably acceptable to DTE Energy, and to have DT Midstream and the members of the DT Midstream Group released from all liability to third parties arising after the date of such novation; provided that neither Party nor any member of its Group shall be required to contribute capital, pay or grant any consideration or concession in any form (including providing any letter of credit, guaranty or other financial accommodation) to any Person in order to cause such novation to be obtained (other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be reimbursed by the Party or the member of the Party’s Group entitled to such Asset or intended to assume such Liability, as applicable, as promptly as reasonably practicable).

SECTION 2.02. Certain Matters Governed Exclusively by Ancillary Agreements. Each of DTE Energy and DT Midstream agrees on behalf of itself and the members of its Group that, except as explicitly provided in this Agreement or in any Ancillary Agreement, (a) the TMA shall exclusively govern all matters relating to Taxes between such parties (except to the extent that tax matters relating to employee and employee benefits-related matters are addressed in the EMA), (b) the EMA shall exclusively govern the allocation of Assets and Liabilities related to employees and employee compensation and benefits matters with respect to employees and former employees of members of both the DTE Energy Group and the DT Midstream Group (except to the extent that employee compensation and benefits-related reimbursements are addressed in the TSA) (it being understood that any such Assets and Liabilities, as allocated pursuant to the EMA, shall constitute DT Midstream Assets, DT Midstream Liabilities, DTE Energy Assets or DTE Energy Liabilities, as applicable, hereunder and shall be subject to Article VI hereof) and (c) the TSA shall exclusively govern all matters relating to the provision of certain services identified therein to be provided by each Party to the other on a transitional basis following the Distribution.

SECTION 2.03. Termination of Agreements; Settlement of Intercompany Accounts; Bank Accounts. (a) Except as set forth in Section 2.03(b) or as otherwise provided by the steps constituting the Internal Transactions, in furtherance of the releases and other provisions of Section 6.01, effective as of the Distribution, DT Midstream and each other member of the DT Midstream Group, on the one hand, and DTE Energy and each other member of the DTE Energy Group, on the other hand, hereby terminate or settle, as applicable, any and all Contracts, agreements, arrangements, commitments and understandings, oral or written,

between such Parties and in existence as of the Distribution Date (“Intercompany Agreements”), including all intercompany payables due or receivables owed (“Intercompany Accounts”), between such Parties (including any such payables or receivable which relate to payroll) and in effect or accrued as of the Distribution Date (except for any such Intercompany Accounts arising pursuant to an Ancillary Agreement or any other Intercompany Agreement that this Agreement or any Ancillary Agreement expressly contemplates will survive the Distribution Date); provided that, notwithstanding anything to the contrary contained herein, (i) if net Intercompany Accounts are due from or owed by any member of the DT Midstream Group to any member of the DTE Energy Group, such Intercompany Accounts shall be settled by contribution to the applicable member of the DT Midstream Group effective as of immediately before the Distribution and (ii) if net Intercompany Accounts are due from or owed by any member of the DTE Energy Group to any member of the DT Midstream Group, such Intercompany Accounts shall be settled by distribution from the applicable member of the DT Midstream Group effective as of immediately before the Internal Distribution. No such terminated Intercompany Agreement or Intercompany Account (including any provision thereof that purports to survive termination) shall be of any further force or effect after the Distribution Date, provided that any Intercompany Account that this Agreement or any Ancillary Agreement expressly contemplates will survive the Distribution Date shall instead be settled in accordance with the terms of such Ancillary Agreement or other Intercompany Agreement. Each Party shall, at the reasonable request of the other Party, take, or cause to be taken, such other actions as may be necessary to effect the foregoing. The Parties, on behalf of the members of their respective Groups, hereby waive any advance notice provision or other termination requirements with respect to any Intercompany Agreement.

(b) The provisions of Section 2.03(a) shall not apply to any of the following Intercompany Agreements or Intercompany Accounts (or to any of the provisions thereof): (i) this Agreement and the Ancillary Agreements (and each other Intercompany Agreement or Intercompany Account expressly contemplated by this Agreement or any Ancillary Agreement to be entered into by either Party or any other member of its Group); (ii) any existing written Intercompany Agreement between a member of the DT Midstream Group, on the one hand, and a member of the DTE Energy Group, on the other hand, that has been entered into in the ordinary course of business on an arm’s-length basis for the provision of services or other commercial arrangement, including outstanding operational intercompany trade receivables or payables incurred on such basis, including those Intercompany Agreements set forth on Schedule XVI; (iii) any Agreements to which any third party is a party, including Shared Contracts; and (iv) any other Intercompany Agreements or Intercompany Accounts that this Agreement or any Ancillary Agreement expressly contemplates will survive the Distribution Date.

(iii) With respect to any outstanding checks issued by, or payments made by, DTE Energy, DT Midstream or any of their respective Subsidiaries prior to the Distribution, such outstanding checks shall be honored from and after the Distribution by the Person or Group owning the account on which the check is drawn, without limiting the ultimate allocation of Liability for such amounts under this Agreement or any Ancillary Agreement.

(iv) As between DTE Energy and DT Midstream (and the members of their respective Groups), except to the extent prohibited by applicable Law or a Final Determination, all payments and reimbursements received after the Distribution by either Party (or a member of its Group) to which the other Party (or a member of its Group) is entitled under this Agreement, shall be held by such Party (or the applicable member of its Group) in trust for the use and benefit of the Person entitled thereto and, within 60 days of receipt by such Party (or the applicable member of its Group) of any such payment or reimbursement, such Party shall pay over, or shall cause the applicable member of its Group to pay over to the other Party (or the applicable member of its Group), the amount of such payment or reimbursement without right of setoff.

division, partial assignment, modification or replication of a Shared Contract unless and until any necessary Consents are obtained or made, as applicable. If the Parties, or their respective Group members, as applicable, are not able to enter into an arrangement to formally divide, partially assign, modify or replicate such Shared Contract prior to the Distribution as contemplated by the previous sentence, then the Parties shall, and shall cause their respective Group members to, cooperate in any reasonable and permissible arrangement to provide that, following the Distribution and until the earlier of two years after the Distribution Date and such time as the formal division, partial assignment, modification or replication of such Shared Contract as contemplated by the previous sentence is effected, a member of the DT Midstream Group shall receive the interest in the benefits and obligations of the DT Midstream Portion under such Shared Contract and a member of the DTE Energy Group shall receive the interest in the benefits and obligations of the DTE Energy Portion under such Shared Contract, it being understood that no Party shall have Liability to the other Party for the failure of any third party to perform its obligations under any such Shared Contract.

(b) Nothing in this Section 2.04 shall require either Party nor any member of their respective Groups to contribute capital, pay or grant any consideration or concession in any form (including providing any letter of credit, guaranty or other financial accommodation) to any Person (other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be reimbursed by the Party or the member of the Party’s Group entitled to such Asset or intended to assume such Liability, as applicable, as promptly as reasonably practicable).

(b) Except as may expressly be set forth herein or in any Ancillary Agreement, any such Assets are being transferred on an “as is”, “where is” basis and the respective transferees shall bear the economic and legal risks that (a) any conveyance shall prove

to be insufficient to vest in the transferee good and marketable title or interest, free and clear of any Security Interest, and (b) any necessary Governmental Approvals or other Consents are not obtained or that any requirements of Laws or judgments are not complied with.

(b) In furtherance of Section 3.01(a), to the extent required to obtain a removal or release from a DTE Energy Credit Support Instrument, DT Midstream or an appropriate member of the DT Midstream Group shall execute an agreement substantially in the form of the existing DTE Energy Credit Support Instrument or such other form as is agreed to by the relevant parties to such agreement, except to the extent that such existing DTE Energy Credit Support Instrument contains representations, covenants or other terms or provisions (i) with which DT Midstream or the appropriate member of the DT Midstream Group would be reasonably unable to comply or (ii) which would be reasonably expected to be breached by DT Midstream or the appropriate member of the DT Midstream Group.

(b) In furtherance of Section 3.02(a), to the extent required to obtain a removal or release from a DT Midstream Credit Support Instrument, DTE Energy or an appropriate member of the DTE Energy Group shall execute an agreement substantially in the form of the existing DT Midstream Credit Support Instrument or such other form as is agreed to by the relevant parties to such agreement, except to the extent that such existing DT Midstream Credit Support Instrument contains representations, covenants or other terms or provisions (A) with which DTE Energy or the appropriate member of the DTE Energy Group would be reasonably unable to comply or (B) which would be reasonably expected to be breached by DTE Energy or the appropriate member of the DTE Energy Group.

thereunder, (ii) with respect to such Credit Support Instruments that are in the form of a letter of credit or bank guarantee, DTE Energy shall provide DT Midstream with letters of credit or guarantees, in each case issued by a bank reasonably acceptable to DT Midstream, against losses arising from all such Credit Support Instruments, or if DT Midstream agrees in writing, cash collateralize the full amount of any outstanding Credit Support Instrument with respect to which such release has not been obtained and (iii) with respect to such Credit Support Instrument, each of DTE Energy and DT Midstream, on behalf of themselves and the members of each of their respective Groups, agree, except as otherwise expressly required by the terms of a Contract with a third party in effect as of the Distribution, not to renew or extend the term of, increase its obligations under or transfer to a third Person, any loan, guarantee, lease, sublease, license, Contract or other obligation for which the other Party or any member of the other Party’s Group is or may be liable under such Credit Support Instrument unless all obligations of the other Party and the other members of the other Party’s Group with respect thereto are thereupon terminated by documentation reasonably satisfactory in form and substance to the other Party. The provisions of clauses (i), (ii) and (iii) of the foregoing sentence shall also apply to all Surviving DT Midstream Credit Support Instruments.

SECTION 3.03. Written Notice of Credit Support Instruments. DTE Energy and DT Midstream shall provide each other with written notice of the existence of all Credit Support Instruments within a reasonable period prior to the Distribution.

Any determination made by the DTE Energy board of directors prior to the Distribution concerning the satisfaction or waiver of any or all of the conditions set forth in this Section 4.02 shall be conclusive.

ARTICLE V

The Distribution

SECTION 5.01. The Distribution. (a) DT Midstream shall cooperate with DTE Energy to accomplish the Distribution and shall, at the direction of DTE Energy, use its reasonable best efforts to promptly take any and all actions necessary or desirable to effect the Distribution. DTE Energy shall select any investment bank or manager in connection with the Distribution, as well as any financial printer, distribution agent and financial, legal, accounting and other advisors for DTE Energy. DTE Energy or DT Midstream, as the case may be, will provide, or cause the applicable member of its Group to provide, to the Agent all share certificates and any information required in order to complete the Distribution.

(b) Subject to the terms and conditions set forth in this Agreement, (i) after completion of the Internal Transactions and on or prior to the Distribution Date, for the benefit of and distribution to the holders of DTE Energy Common Stock as of the Record Date (“Record Holders”), DTE Energy will deliver to the Agent all of the issued and outstanding shares of DT Midstream Common Stock held by DTE Energy or any other member of the DTE Energy Group and book-entry authorizations for such shares and (ii) on the Distribution Date, DTE Energy shall instruct the Agent to distribute, by means of a pro rata dividend based on the aggregate number of shares of DTE Energy Common Stock held by each applicable Record Holder, to each Record Holder (or such Record Holder’s bank, brokerage firm, trustee or other nominee on such Record Holder’s behalf) electronically, by direct registration in book-entry form, the number of shares of DT Midstream Common Stock to which such Record Holder is entitled based on a distribution ratio determined by DTE Energy in its sole discretion. The Distribution shall be effective at 12:01 a.m. New York City time on the Distribution Date. On or as soon as practicable after the Distribution Date, the Agent will mail to each Record Holder (or such Record Holder’s bank, brokerage firm, trustee or other nominee on such Record Holder’s behalf, as applicable) an account statement indicating the number of shares of DT Midstream Common Stock that have been registered in book-entry form in the name of such Record Holder.

SECTION 5.02. Fractional Shares. Record Holders holding a number of shares of DTE Energy Common Stock on the Record Date that would entitle such holders to receive less than one whole share (in addition to any whole shares) of DT Midstream Common Stock in the Distribution will receive cash in lieu of such fractional share. Fractional shares of DT Midstream Common Stock will not be distributed in the Distribution nor credited to book-entry accounts. The Agent and DTE Energy shall, as soon as practicable after the date on which “when-issued” trading of the DT Midstream Common Stock begins on the Exchange, (a) determine the number of whole shares and fractional shares of DT Midstream Common Stock allocable to each Record Holder and (b) aggregate all fractional shares of DT Midstream Common Stock into whole shares and sell the whole shares obtained thereby in open market transactions at then prevailing trading prices on behalf of holders who would otherwise be entitled to fractional share interests. DTE Energy shall cause the Agent to, as soon as practicable after the Distribution Date, distribute to each such holder, or for the benefit of each beneficial owner, such holder’s or owner’s ratable share of the net proceeds of such sale, based upon the average gross selling price per share of DT Midstream Common Stock after making appropriate deductions for any amount required to be withheld under applicable Tax Law and less any brokers’ charges, commissions or transfer Taxes. The Agent, in its sole discretion, will determine the timing and method of selling such fractional shares of DT Midstream Common Stock, the selling price of such fractional shares and the broker dealer through which such fractional shares will be sold; provided, however, that the designated broker dealer is not an Affiliate of DTE Energy or DT Midstream. Neither DTE Energy nor DT Midstream will pay any interest on the proceeds from the sale of fractional shares of DT Midstream Common Stock.

SECTION 5.03. Sole Discretion of DTE Energy. DTE Energy shall, in its sole and absolute discretion, determine the Record Date, the Distribution Date and all terms of the Distribution, including the form, structure and terms of any transactions or offerings to effect

the Distribution and the timing of and conditions to the consummation thereof. In addition and notwithstanding anything to the contrary set forth below, DTE Energy may at any time and from time to time until the Distribution decide to abandon the Distribution or modify or change the terms of the Distribution, including by accelerating or delaying the timing of the consummation of all or part of the Distribution.

ARTICLE VI

Mutual Releases; Indemnification; Litigation

SECTION 6.01. Release of Pre-Distribution Claims. (a) Except as provided in Section 6.01(d) or elsewhere in this Agreement or in the Ancillary Agreements, effective as of the Distribution, DT Midstream does hereby, for itself and each other member of the DT Midstream Group, their respective Affiliates, and to the extent it may legally do so, successors and assigns and all Persons who at any time on or prior to the Distribution have been shareholders, directors, officers, members, agents or employees of any member of the DT Midstream Group (in each case, in their respective capacities as such), remise, release and forever discharge DTE Energy and the other members of the DTE Energy Group, their respective Affiliates, successors and assigns, and all Persons who at any time on or prior to the Distribution have been shareholders, directors, officers, members, agents or employees of any member of the DTE Energy Group (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns, from any and all DT Midstream Liabilities whatsoever, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, existing or arising from any acts or events occurring or failing to occur, or alleged to have occurred, or to have failed to occur, or any conditions existing or alleged to have existed on or before the Distribution, including in connection with the Spin-Off and all other activities to implement the Spin-Off. This Section 6.01(a) shall not affect DTE Energy’s indemnification obligations with respect to Liabilities arising on or before the Distribution Date under Article VII of its Amended and Restated Articles of Incorporation, as in effect on the date on which the event or circumstances giving rise to such indemnification obligation occur.

(b) Except as provided in Section 6.01(d) or elsewhere in this Agreement or in the Ancillary Agreements, effective as of the Distribution, DTE Energy does hereby, for itself and each other member of the DTE Energy Group, their respective Affiliates, and to the extent it may legally do so, successors and assigns and all Persons who at any time on or prior to the Distribution have been shareholders, directors, officers, agents or employees of any member of the DTE Energy Group (in each case, in their respective capacities as such), remise, release and forever discharge DT Midstream and the other members of the DT Midstream Group, their respective Affiliates, successors and assigns, and all Persons who at any time on or prior to the Distribution have been shareholders, directors, officers, agents or employees of any member of the DT Midstream Group (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns, from any and all DTE Energy Liabilities whatsoever, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, existing or arising from any acts or events occurring, or failing to occur, or alleged to have occurred, or to have failed to occur, or any conditions existing or alleged to have existed on or before the Distribution, including in connection with the Spin-Off and all other activities to implement the Spin-Off.

(c) The Parties expressly understand and acknowledge that it is possible that unknown losses or claims exist or might come to exist or that present losses may have been underestimated in amount, severity, or both. Accordingly, the Parties are deemed expressly to understand and acknowledge any federal or state law or right, rule or legal principle of the State of Delaware which provides that: A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH A CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN SUCH CREDITOR’S FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY SUCH CREDITOR MUST HAVE MATERIALLY AFFECTED SUCH CREDITOR’S SETTLEMENT WITH A DEBTOR. The Parties are hereby deemed to agree that any such or similar federal or state laws or rights, rules or legal principles of the State of Delaware or any other jurisdiction that may be applicable herein, are hereby knowingly and voluntarily waived and relinquished with respect to the releases in Section 6.01(a) and (b).

(d) Nothing contained in Section 6.01(a) or (b) shall impair any right of any Person to enforce this Agreement, any Ancillary Agreement or any Intercompany Agreement or Intercompany Account that is specified in Section 2.03(b) not to terminate as of the Distribution, in each case in accordance with its terms. Nothing contained in Section 6.01(a) or (b) shall release:

(i) any Person from any Liability provided in or resulting from any Contract among any members of the DTE Energy Group or the DT Midstream Group that is specified in Section 2.03(b) as not to terminate as of the Distribution, or any other Liability specified in such Section 2.03(b) as not to terminate as of the Distribution;

(ii) any Person from any Liability, contingent or otherwise, assumed, transferred, assigned or allocated to the Group of which such Person is a member in accordance with, or any other Liability of any member of any Group under, this Agreement or any Ancillary Agreement;

(iii) any Person from any Liability provided in or resulting from any other Contract or agreement that is entered into after the Distribution between one Party (or a member of such Party’s Group), on the one hand, and the other Party (or a member of such Party’s Group), on the other hand;

(iv) any Person from any Liability that the Parties may have with respect to indemnification or contribution pursuant to this Agreement or any Ancillary Agreement for claims brought against the Parties, the members of their respective Groups or any of their respective directors, officers, employees or agents, by third Persons, which Liability shall be governed by the provisions of this Article VI or, if applicable, the appropriate provisions of the relevant Ancillary Agreement;

(v) any Person from any Liability the release of which would result in the release of any Person not otherwise intended to be released pursuant to this Section 6.01; or

(vi) any Persons (other than each member of the DTE Energy Group and its successors and assigns and each member of the DT Midstream Group and its successors and assigns) that at any time prior to the Distribution have been current or former shareholders, directors, officers, employees or agents of any member of the DTE Energy Group or any member of the DT Midstream Group (in each case, in their respective capacities as such), or their respective heirs, executors, administrators, successors and assigns, from any and all DTE Energy Liabilities or DT Midstream Liabilities whatsoever, whether at Law or in equity (including any right of contribution), whether arising under any contract or agreement, by operation of Law or otherwise.

In addition, nothing contained in Section 6.01(a) shall release: (A) DTE Energy from indemnifying any director, officer or employee of the DT Midstream Group who was a director, officer or employee of DTE Energy or any of its Affiliates at or prior to the Distribution, to the extent such director, officer or employee is or becomes a named defendant in any Action with respect to which he or she was entitled to such indemnification from a member of the DTE Energy Group pursuant to then-existing obligations, it being understood that if the underlying obligation giving rise to such Action is a DT Midstream Liability, DT Midstream shall indemnify DTE Energy for such Liability (including DTE Energy’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article VI; and (B) DT Midstream from indemnifying any director, officer or employee of the DTE Energy Group who was a director, officer or employee of DTE Energy or any of its Affiliates at or prior to the Distribution, to the extent such director, officer or employee is or becomes a named defendant in any Action with respect to which he or she was entitled to such indemnification from a member of the DT Midstream Group pursuant to then-existing obligations, it being understood that if the underlying obligation giving rise to such Action is a DTE Energy Liability, DTE Energy shall indemnify DT Midstream for such Liability (including DT Midstream’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article VI.

(e) DT Midstream shall not make, and shall not permit any other member of the DT Midstream Group to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or any indemnification, against DTE Energy or any other member of the DTE Energy Group, or any other Person released pursuant to Section 6.01(a), with respect to any Liabilities released pursuant to Section 6.01(a). DTE Energy shall not make, and shall not permit any other member of the DTE Energy Group to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or any indemnification against DT Midstream or any other member of the DT Midstream Group, or any other Person released pursuant to Section 6.01(b), with respect to any Liabilities released pursuant to Section 6.01(b).

(f) It is the intent of each of DTE Energy and DT Midstream, by virtue of the provisions of this Section 6.01, to provide for a full and complete release and discharge of all Liabilities existing or arising from all acts and events occurring, or failing to occur, or alleged to have occurred, or to have failed to occur, and all conditions existing or alleged to have existed on or before the Distribution Date, between or among DT Midstream or any other member of the DT Midstream Group, on the one hand, and DTE Energy or any other member of the DTE Energy Group, on the other hand (including any contractual agreements or arrangements existing

or alleged to exist between or among any such members on or before the Distribution Date), except as expressly set forth in Section 6.01(d) or elsewhere in this Agreement or in any Ancillary Agreement. At any time, at the request of the other Party, each Party shall cause each member of its respective Group to execute and deliver releases reflecting the provisions hereof.

SECTION 6.02. Indemnification by DT Midstream. Subject to Section 6.04, DT Midstream shall indemnify, defend and hold harmless DTE Energy, each other member of the DTE Energy Group and each of their respective former and current directors, officers and employees, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “DTE Energy Indemnitees”), from and against any and all Liabilities of the DTE Energy Indemnitees relating to, arising out of or resulting from any of the following items (without duplication):

(a) the DT Midstream Liabilities, including the failure of DT Midstream or any other member of the DT Midstream Group or any other Person to pay, perform or otherwise promptly discharge any DT Midstream Liability in accordance with its terms;

(b) any breach by DT Midstream or any other member of the DT Midstream Group of this Agreement or any Ancillary Agreement unless such Ancillary Agreement expressly provides for separate or conflicting indemnification therein (which shall be controlling); and

(c) any breach by DT Midstream of any of the representations and warranties made by DT Midstream on behalf of itself and the members of the DT Midstream Group in Section 11.01(c).

SECTION 6.03. Indemnification by DTE Energy. Subject to Section 6.04, DTE Energy shall indemnify, defend and hold harmless DT Midstream, each other member of the DT Midstream Group and each of their respective former and current directors, officers and employees, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “DT Midstream Indemnitees”), from and against any and all Liabilities of the DT Midstream Indemnitees relating to, arising out of or resulting from any of the following items (without duplication):

(a) the DTE Energy Liabilities, including the failure of DTE Energy or any other member of the DTE Energy Group or any other Person to pay, perform or otherwise promptly discharge any DTE Energy Liability in accordance with its terms;

(b) any breach by DTE Energy or any other member of the DTE Energy Group of this Agreement or any Ancillary Agreement unless such Ancillary Agreement expressly provides for separate or conflicting indemnification therein (which shall be controlling); and

(c) any breach by DTE Energy of any of the representations and warranties made by DTE Energy on behalf of itself and the members of the DTE Energy Group in Section 11.01(c).

SECTION 6.04. Indemnification Obligations Net of Insurance Proceeds and Third-Party Proceeds. (a) The Parties intend that any Liability subject to indemnification or reimbursement pursuant to this Agreement will be net of (i) Insurance Proceeds that actually reduce the amount of, or are paid to the applicable Indemnitee in respect of, such Liability and (ii) other amounts recovered from any third party (net of any out-of-pocket costs or expenses incurred in, or Taxes imposed with respect to, the collection thereof) that actually reduce the amount of, or are paid to the applicable Indemnitee in respect of, such Liability (“Third-Party Proceeds”). Accordingly, the amount that either Party (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification or reimbursement pursuant to this Agreement (an “Indemnitee”) will be reduced by any Insurance Proceeds or Third-Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee from a third party in respect of the related Liability. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party in respect of any Liability (an “Indemnity Payment”) and subsequently receives Insurance Proceeds or Third-Party Proceeds in respect of such Liability, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if such Insurance Proceeds or Third-Party Proceeds had been received, realized or recovered before the Indemnity Payment was made; provided, that for the avoidance of doubt, such amount shall not exceed the amount of the Indemnity Payment.

(b) An insurer that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or have any subrogation rights with respect thereto by virtue of the indemnification provisions hereof, it being expressly understood and agreed that no insurer or any other third party shall be entitled to a “wind-fall” (i.e., a benefit to which an insurer or any other third party would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification provisions hereof. Subject to Section 6.12, each member of the DTE Energy Group and DT Midstream Group shall use reasonable best efforts to seek to collect or recover any Insurance Proceeds and any Third-Party Proceeds to which such Person is entitled in connection with any Liability for which such Person seeks indemnification pursuant to this Article VI; provided, however, that such Person’s inability to collect or recover any such Insurance Proceeds or Third-Party Proceeds shall not limit the Indemnifying Party’s obligations hereunder.

SECTION 6.05. Procedures for Indemnification of Third-Party Claims. (a) If an Indemnitee shall receive notice or otherwise learn of a Third-Party Claim with respect to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee pursuant to this Agreement or any Ancillary Agreement, such Indemnitee shall give such Indemnifying Party written notice thereof as soon as reasonably practicable, but no later than 30 days after becoming aware of such Third-Party Claim. Any such notice shall describe the Third-Party Claim in reasonable detail and include copies of all notices and documents (including demand letters and motions, pleadings and other court papers) received by the Indemnitee relating to the Third-Party Claim. Notwithstanding the foregoing, the failure of any Indemnitee or other Person to give notice as provided in this Section 6.05(a) shall not relieve the Indemnifying Party from which indemnification hereunder is sought of its obligations under this Article VI, except to the extent that such Indemnifying Party is actually prejudiced by such failure to give notice in accordance with this Section 6.05(a).

(b) The Indemnifying Party shall have the right, exercisable by written notice to the Indemnitee within 30 days after receipt of notice from an Indemnitee in accordance with Section 6.05(a) (or sooner, if the nature of such Third-Party Claim so requires), to assume and conduct the defense of such Third-Party Claim in accordance with the limits set forth in this Agreement with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnitee; provided, however, that (x) DT Midstream shall not be entitled to control the defense of any Third-Party Claim in respect of a Mixed Action and (y) the Indemnifying Party shall not have the right to control the defense of any Third-Party Claim (i) to the extent such Third-Party Claim seeks criminal penalties or injunctive or other equitable relief (other than any such injunctive or other equitable relief that is solely incidental to the granting of money damages) or (ii) if the Indemnitee has reasonably determined in good faith that the Indemnifying Party controlling such defense will affect the Indemnitee or its Group in a materially adverse manner.

(c) If the Indemnifying Party elects not to assume the defense of a Third-Party Claim (or is not permitted to assume the defense of such Third-Party Claim) in accordance with this Agreement, or fails to notify an Indemnitee of its election as provided in Section 6.05(b), such Indemnitee may defend such Third-Party Claim. If the Indemnifying Party elects (and is permitted) to assume the defense of a Third-Party Claim in accordance with the terms of this Agreement, the Indemnitees shall, subject to the terms of this Agreement, cooperate with the Indemnifying Party with respect to the defense of such Third-Party Claim.

(d) If the Indemnifying Party elects (and is permitted) to assume the defense of a Third-Party Claim in accordance with the terms of this Agreement, the Indemnifying Party will not be liable for any additional legal expenses subsequently incurred by the Indemnitee in connection with the defense of the Third-Party Claim; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third-Party Claim, or the nature of such Third-Party Claim changes such that the Indemnifying Party would no longer be entitled to assume the defense of such Third-Party Claim pursuant to Section 6.05(b), the Indemnitee may assume its own defense, and the Indemnifying Party will be liable for all reasonable costs or expenses paid or incurred in connection with such defense. The Indemnifying Party or the Indemnitee, as the case may be, shall have the right to participate in (but, subject to the prior sentence, not control), at its own expense, the defense of any Third-Party Claim that the other is defending as provided in this Agreement. In the event, however, that such Indemnitee reasonably determines that representation by counsel to the Indemnifying Party of both such Indemnifying Party and the Indemnitee could reasonably be expected to present such counsel with a conflict of interest, then the Indemnitee may employ separate counsel to represent or defend it in any such action or proceeding and the Indemnifying Party will pay the reasonable fees and expenses of such counsel.

(e) No Indemnifying Party shall consent to entry of any judgment or enter into any settlement of any Third-Party Claim without the consent of the applicable Indemnitee or Indemnitees; provided, however, that such consent shall not be required if the judgment or settlement: (i) contains no finding or admission of Liability with respect to any such Indemnitee

or Indemnitees; (ii) involves only monetary relief which the Indemnifying Party has agreed to pay; and (iii) includes a full and unconditional release of the Indemnitee or Indemnitees. Notwithstanding the foregoing, the consent of an Indemnitee (not to be unreasonably withheld, conditioned or delayed) shall be required for any entry of judgment or settlement if the effect thereof is to permit any injunction, declaratory judgment, other order or other non-monetary relief to be entered, directly or indirectly, against such Indemnitee.

(f) Whether or not the Indemnifying Party assumes the defense of a Third-Party Claim, no Indemnitee shall admit any liability with respect to, or settle, compromise or discharge, such Third-Party Claim without the Indemnifying Party’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

SECTION 6.06. Additional Matters. (a) Any claim on account of a Liability that does not result from a Third-Party Claim shall be asserted by written notice given by the Indemnitee to the Indemnifying Party from which indemnification hereunder is sought. Any failure by an Indemnitee to give notice shall not relieve the Indemnifying Party’s indemnification obligations under this Agreement, except to the extent that the Indemnifying Party shall have been actually prejudiced by such failure. Such Indemnifying Party shall have a period of 60 days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such 60-day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment. If such Indemnifying Party does not respond within such 60-day period or rejects such claim in whole or in part, such Indemnitee shall be free to pursue such remedies as may be available to such Party as contemplated by this Agreement.

(b) In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third-Party Claim, such Indemnifying Party shall be subrogated to, and shall stand in the place of, such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third-Party Claim against any claimant or plaintiff asserting such Third-Party Claim or against any other Person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

(c) In the event of an Action with respect to which indemnification may be sought hereunder and in which the Indemnifying Party is not a named defendant, if either the Indemnitee or Indemnifying Party shall so request, the Parties shall endeavor to substitute the Indemnifying Party for the named defendant. If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in Section 6.12, and the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts fees and all other external expenses), the costs of any judgment or settlement and the cost of any interest or penalties relating to any judgment or settlement.

(d) If (i) a Party incurs any Liability arising out of this Agreement or any Ancillary Agreement; (ii) an adequate legal or equitable remedy is not available for any reason

against the other Party to satisfy the Liability incurred by the incurring Party; and (iii) a legal or equitable remedy may be available to the other Party against a third party for such Liability, then the other Party shall use its commercially reasonable efforts to cooperate with the incurring Party, at the incurring Party’s expense, to permit the incurring Party to obtain the benefits of such legal or equitable remedy against such third party.

SECTION 6.07. Right to Contribution. (a) If any right of indemnification contained in Section 6.02 or Section 6.03 is held unenforceable or is unavailable for any reason, or is insufficient to hold harmless any Indemnitee in respect of any Liability for which such Indemnitee is entitled to indemnification hereunder, then the Indemnifying Party shall contribute to the amounts paid or payable by any Indemnitees as a result of such Liability (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the members of its Group, on the one hand, and such Indemnitee and any other Indemnitees entitled to contribution in respect of such Liability, on the other hand, as well as any other relevant equitable considerations.

(b) Solely for purposes of determining relative fault pursuant to this Section 6.07: (i) any fault associated with the business conducted with DT Midstream Assets or the DT Midstream Liabilities (except for the gross negligence or willful misconduct of a member of the DTE Energy Group) or with the ownership, operation or activities of the DT Midstream Business prior to the Distribution shall be deemed to be the fault of DT Midstream and the other members of the DT Midstream Group, and no such fault shall be deemed to be the fault of DTE Energy or any other member of the DTE Energy Group; and (ii) any fault associated with the business conducted with DTE Energy Assets or the DTE Energy Liabilities (except for the gross negligence or willful misconduct of a member of the DT Midstream Group) shall be deemed to be the fault of DTE Energy and the other members of the DTE Energy Group, and no such fault shall be deemed to be the fault of DT Midstream or any other member of the DT Midstream Group.

SECTION 6.08. Remedies Cumulative. The remedies provided in this Article VI shall be cumulative and, subject to the provisions of Section 6.10 and Article X, shall not preclude assertion by any Indemnitee of any other rights or the seeking of any and all other remedies against any Indemnifying Party.

SECTION 6.09. Survival of Indemnities. The rights and obligations of each of DTE Energy and DT Midstream and their respective Indemnitees under this Article VI shall survive the sale or other transfer by any Party or its Affiliates of any Assets or businesses or the assignment by it of any Liabilities.

SECTION 6.10. Limitation on Liability. Except as may expressly be set forth in this Agreement, none of DTE Energy, DT Midstream or any other member of either Group shall in any event have any Liability to the other or to any other member of the other’s Group, or to any other DTE Energy Indemnitee or DT Midstream Indemnitee, as applicable, under this Agreement (i) with respect to any matter to the extent that the Party seeking indemnification has engaged in any violation of Law or fraud in connection therewith or (ii) for any indirect, special, punitive or consequential damages, whether or not caused by or resulting from negligence or breach of obligations hereunder and whether or not informed of the

possibility of the existence of such damages; provided, however, that the provisions of this Section 6.10(ii) shall not limit an Indemnifying Party’s indemnification obligations hereunder with respect to any Liability any Indemnitee may have to any third party not affiliated with any member of the DTE Energy Group or the DT Midstream Group, as applicable, for any indirect, special, punitive or consequential damages. Notwithstanding the foregoing, nothing in this Section 6.10 shall limit the Liability of DTE Energy, DT Midstream or any other member of either Group to the other or to any other member of the other’s Group, or to any other DTE Energy Indemnitee or DT Midstream Indemnitee, as applicable, with respect to breaches of Section 7.01, Section 7.04, Section 7.05, Section 7.07 or Section 7.09.

SECTION 6.11. Covenant Not to Sue. Each Party hereby covenants and agrees that none of it, the members of such Party’s Group or any Person claiming on behalf of such Party or such Group shall bring suit or otherwise assert any claim against any Indemnitee, or assert a defense against any claim asserted by any Indemnitee, before any Governmental Authority, alleging that: (a) the assumption of any DT Midstream Liabilities by DT Midstream or any other member of the DT Midstream Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; (b) the retention of any DTE Energy Liabilities by DTE Energy or any other member of the DTE Energy Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; or (c) the provisions of this Article VI are void or unenforceable for any reason.

SECTION 6.12. Management of Actions. This Section 6.12 shall govern the management and direction of pending and future Actions in which members of the DTE Energy Group or the DT Midstream Group are named as parties, but shall not alter the allocation of Liabilities set forth in Article II unless otherwise expressly set forth in this Section 6.12.

(a) From and after the Distribution, the DT Midstream Group shall direct the defense or prosecution of any (i) Actions set forth on Schedule XI and (ii) Actions (other than Actions set forth on Schedule XI, Schedule XII or Schedule XIII) that constitute only DT Midstream Liabilities or involve only DT Midstream Assets.

(b) From and after the Distribution, the DTE Energy Group shall direct the defense or prosecution of any (i) Actions set forth on Schedule XII and (ii) Actions (other than Actions set forth on Schedule XI, Schedule XII or Schedule XIII) that constitute only DTE Energy Liabilities or involve only DTE Energy Assets.

(c) From and after the Distribution, the Parties shall separately but cooperatively manage (whether as co-defendants or co-plaintiffs) any (i) Actions set forth in Schedule XIII and (ii) Actions (other than Actions set forth on Schedule XI, Schedule XII or Schedule XIII) that constitute both a DTE Energy Asset or DTE Energy Liability, on the one hand, and a DT Midstream Asset or a DT Midstream Liability, on the other hand (such Actions in clauses (i) and (ii), the “Mixed Actions”). The Parties shall cooperate in good faith and take all reasonable actions to provide for any appropriate joinder or change in named parties to such Mixed Actions such that the appropriate member of each Party or Group is party thereto. The Parties shall reasonably cooperate and consult with each other, and to the extent permissible and necessary or advisable, maintain a joint defense in a manner that would preserve for both Parties

and their respective Affiliates any attorney-client privilege, joint defense or other privilege with respect to any Mixed Action. Notwithstanding anything to the contrary herein, and except as set forth in Schedule XIII, the Parties may jointly retain counsel (in which case the cost of counsel shall be shared equally by the Parties) or retain separate counsel (in which case each Party will bear the cost of its separate counsel) with respect to any Mixed Action; provided that the Parties shall bear their own discovery costs and shall share equally joint litigation costs. In any Mixed Action, each of DTE Energy and DT Midstream may pursue separate defenses, claims, counterclaims or settlements to those claims relating to the DTE Energy Business or the DT Midstream Business, respectively; provided that each Party shall in good faith make reasonable best efforts to avoid adverse effects on the other Party.

(d) To the maximum extent permitted by applicable Law, the rights to recovery of each Party’s Subsidiaries in respect of any past, present or future Action are hereby delegated to such Party. It is the intent of the Parties that the foregoing delegation shall satisfy any Law requiring such delegation to be effected pursuant to a power of attorney or similar instrument. The Parties and their respective Subsidiaries shall execute such further instruments or documents as may be necessary to effect such delegation.

SECTION 6.13. Settlement of Actions. No Party managing an Action (the “Managing Party”) pursuant to Section 6.12 shall consent to entry of any judgment or enter into any settlement of any such Action without the prior written consent of the other Party (the “Non-Managing Party”) (not to be unreasonably withheld, conditioned or delayed); provided, however, that such Non-Managing Party, including, in the case of a Mixed Action, any co-defendant or co-plaintiff, shall be required to consent to such entry of judgment or to such settlement that the Managing Party may recommend if the judgment or settlement: (i) contains no finding or admission of any violation of Law or any violation of the rights of any Person; (ii) involves only monetary relief which the Managing Party has agreed to pay; and (iii) includes a full and unconditional release of the Non-Managing Party and its applicable related Persons. Notwithstanding the foregoing, in no event shall a Non-Managing Party be required to consent to an entry of judgment or settlement if the effect thereof is to permit any injunction, declaratory judgment, other order or other non-monetary relief to be entered, directly or indirectly, against the Non-Managing Party’s Group (other than the determination of equitable relief incidental to the granting of monetary relief).

ARTICLE VII

Access to Information; Privilege; Confidentiality

SECTION 7.01. Agreement for Exchange of Information; Archives. (a) Except in the case of an Adversarial Action or threatened Adversarial Action, and subject to Section 7.01(b), each of DTE Energy and DT Midstream, on behalf of its respective Group, shall provide, or cause to be provided, to the other Party, at any time after the Distribution, as soon as reasonably practicable after written request therefor, any Information relating to time periods on or prior to the Distribution Date in the possession or under the control of such respective Group, which DTE Energy or DT Midstream, or any member of its respective Group, as applicable, reasonably needs (i) to comply with reporting, disclosure, filing or other requirements imposed on DTE Energy or DT Midstream, or any other member of its respective Group, as applicable

(including under applicable securities Laws), by any national securities exchange or any Governmental Authority having jurisdiction over DTE Energy or DT Midstream, or any other member of its respective Group, as applicable, (ii) for use in any other judicial, regulatory, administrative or other proceeding or in order to satisfy audit, accounting, regulatory, litigation or other similar requirements or (iii) to comply with its obligations under this Agreement or any Ancillary Agreement; provided, that any request for information pursuant to this Section 7.01 shall be made in good faith and limited to the extent reasonable to satisfy the good faith basis for such request. The receiving Party shall use any Information received pursuant to this Section 7.01(a) solely to the extent reasonably necessary to satisfy the applicable obligations or requirements described in clause (i), (ii) or (iii) of the immediately preceding sentence.

(b) In the event that either DTE Energy or DT Midstream determines that the disclosure of any Information pursuant to Section 7.01(a) could be commercially detrimental, violate any Law or Contract or waive or jeopardize any attorney-client privilege, attorney work product protection or other similar privilege or doctrine, such Party shall not be required to provide access to or furnish such Information to the other Party; provided, however, that both DTE Energy and DT Midstream shall take all commercially reasonable measures to permit compliance with Section 7.01(a) in a manner that avoids any such harm or consequence. Both DTE Energy and DT Midstream intend that any provision of access to or the furnishing of Information pursuant to this Section 7.01 that would otherwise be within the ambit of any legal privilege shall not operate as waiver of such privilege.

(c) Each of DT Midstream and DTE Energy agrees, on behalf of itself and each member of the Group of which it is a member, not to disclose or otherwise waive any privilege or protection attaching to any privileged Information relating to a member of the other Group or relating to or arising in connection with the relationship between the Groups at or prior to the Distribution, without providing prompt written notice to and obtaining the prior written consent of the other (not to be unreasonably withheld, conditioned or delayed).

(d) DTE Energy and DT Midstream each agree, on behalf of itself and each member of its respective Group, that it will only process personal data provided to it by the other Group in accordance with all applicable privacy and data protection law obligations (including, to the extent copies of the applicable privacy policies have been provided by one Party to the other, any applicable privacy policies of the DT Midstream Group or the DTE Energy Group, as the case may be) and will implement and maintain at all times appropriate technical and organizational measures to protect such personal data against unauthorized or unlawful processing and accidental loss, destruction, damage, alteration and disclosure. In addition, each Party agrees to provide reasonable assistance to the other Party in respect of any obligations under privacy and data protection legislation affecting the disclosure of such personal data to the other Party and will not knowingly process such personal data in such a way as to cause the other Party to violate any of its obligations under any applicable privacy and data protection legislation.

(e) Without limiting the generality of the foregoing, at any time after the Distribution, if any member of the DTE Energy Group identifies any Information in its possession or under its control (i) that pertains to any DT Midstream Group facilities before the Distribution and (ii) which has not already been delivered to DT Midstream prior to or in

connection with the Distribution, it shall deliver such Information as soon as reasonably practicable to DT Midstream, subject to the provisions of this Article VII. For the avoidance of doubt, nothing in this Section 7.01(e) shall require any member of the DTE Energy Group to conduct any general search or investigation of its files for such Information.

SECTION 7.02. Ownership of Information. Any Information owned by one Group that is provided to the requesting Party hereunder shall be deemed to remain the property of the providing Party. Except as specifically set forth herein or in any Ancillary Agreement, nothing herein shall be construed as granting or conferring rights of license or otherwise in any such Information.

SECTION 7.03. Compensation for Providing Information. DTE Energy and DT Midstream shall reimburse each other for the reasonable costs, if any, in complying with a request for Information pursuant to this Article VII (whether or not such Information was a DT Midstream Asset or a DTE Energy Asset). Except as may be otherwise specifically provided elsewhere in this Agreement, such costs shall be computed in accordance with DT Midstream’s or DTE Energy’s, as applicable, standard methodology and procedures, but shall not include any mark-up above actual costs.

SECTION 7.04. Record Retention. To facilitate the possible exchange of Information pursuant to this Article VII and other provisions of this Agreement, each Party shall use its reasonable best efforts to retain all Information in such Party’s possession relating to the other Party or its businesses, Assets or Liabilities, this Agreement or the Ancillary Agreements (the “Retained Information”) in accordance with its respective record retention policies as in effect on the date hereof or such longer period as required by Law, this Agreement or the Ancillary Agreements. Each of DTE Energy and DT Midstream shall use its reasonable best efforts to maintain and continue their respective Group’s compliance with all “litigation holds” applicable to any Information in its possession for the pendency of the applicable matter.

SECTION 7.05. Accounting Information. Without limiting the generality of Section 7.01 but subject to Section 7.01(b):

(a) Until the end of the first full fiscal year occurring after the Distribution Date (and for a reasonable period of time afterwards or as required by Law for DTE Energy to prepare consolidated financial statements or complete a financial statement audit for any period during which the financial results of the DT Midstream Group were consolidated with those of DTE Energy), DT Midstream shall use its reasonable best efforts to enable and assist DTE Energy to meet its timetable for preparation of its financial statements and to enable and assist DTE Energy’s auditors to timely complete their annual audit and quarterly reviews of financial statements. As part of such efforts, to the extent reasonably necessary for the preparation of financial statements or completing an audit or review of financial statements or an audit of internal control over financial reporting, (i) DT Midstream shall authorize and direct its auditors to make available to DTE Energy’s auditors, within a reasonable time prior to the date of DTE Energy’s auditors’ opinion or review report, both (x) the personnel who performed or will perform the annual audits and quarterly reviews of DT Midstream and (y) work papers to the extent related to such annual audits and quarterly reviews, to enable and assist DTE Energy’s auditors to perform any procedures they consider reasonably necessary to take responsibility for

the work of DT Midstream’s auditors as it relates to DTE Energy’s auditors’ opinion or report and (ii) until all governmental audits are complete, DT Midstream shall provide reasonable access during normal business hours for DTE Energy’s internal auditors, counsel and other designated representatives to (x) the premises of DT Midstream and its Subsidiaries and all Information (and duplicating rights) within the knowledge, possession or control of DT Midstream and its Subsidiaries and (y) the officers and employees of DT Midstream and its Subsidiaries, so that DTE Energy may conduct reasonable audits relating to the financial statements provided by DT Midstream and its Subsidiaries; provided, however, that such access shall not be unreasonably disruptive to the business and affairs of the DT Midstream Group.

(b) Until the end of the first full fiscal year occurring after the Distribution Date (and for a reasonable period of time afterwards or as required by Law), DTE Energy shall use its reasonable best efforts to enable and assist DT Midstream to meet its timetable for dissemination of its financial statements and to enable and assist DT Midstream’s auditors to timely complete their annual audit and quarterly reviews of financial statements. As part of such efforts, to the extent reasonably necessary for the preparation of financial statements or completing an audit or review of financial statements or an audit of internal control over financial reporting, (i) DTE Energy shall authorize and direct its auditors to make available to DT Midstream’s auditors, within a reasonable time prior to the date of DT Midstream’s auditors’ opinion or review report, both (x) the personnel who performed or will perform the annual audits and quarterly reviews of DTE Energy and (y) work papers related to such annual audits and quarterly reviews, to enable and assist DT Midstream’s auditors to perform any procedures they consider reasonably necessary to take responsibility for the work of DTE Energy’s auditors as it relates to DT Midstream’s auditors’ opinion or report and (ii) until all governmental audits are complete, DTE Energy shall provide reasonable access during normal business hours for DT Midstream’s internal auditors, counsel and other designated representatives to (x) the premises of DTE Energy and its Subsidiaries and all Information (and duplicating rights) within the knowledge, possession or control of DTE Energy and its Subsidiaries and (y) the officers and employees of DTE Energy and its Subsidiaries, so that DT Midstream may conduct reasonable audits relating to the financial statements provided by DTE Energy and its Subsidiaries; provided, however, that such access shall not be unreasonably disruptive to the business and affairs of the DTE Energy Group.

(c) In order to enable the principal executive officer(s) and principal financial officer(s) (as such terms are defined in the rules and regulations of the Commission) of DTE Energy to make any certifications required of them under Section 302 or 906 of the Sarbanes-Oxley Act of 2002, DT Midstream shall, within a reasonable period of time following a request from DTE Energy in anticipation of filing such reports, cause its principal executive officer(s) and principal financial officer(s) to provide DTE Energy with certifications of such officers in support of the certifications of DTE Energy’s principal executive officer(s) and principal financial officer(s) required under Section 302 or 906 of the Sarbanes-Oxley Act of 2002 with respect to DTE Energy’s Quarterly Report on Form 10-Q filed with respect to the fiscal quarter during which the Distribution Date occurs (unless such quarter is the fourth fiscal quarter), each subsequent fiscal quarter through the third fiscal quarter of the year in which the Distribution Date occurs and DTE Energy’s Annual Report on Form 10-K filed with respect to the fiscal year during which the Distribution Date occurs. Such certifications shall be provided in substantially the same forms and manners as such DT Midstream officers provided prior to the Distribution (reflecting any changes in certifications necessitated by the Spin-Off or any other transactions related thereto) or as otherwise agreed upon between DTE Energy and DT Midstream.

SECTION 7.06. Limitations of Liability. (a) Each of DTE Energy (on behalf of itself and each other member of the DTE Energy Group) and DT Midstream (on behalf of itself and each other member of the DT Midstream Group) understands and agrees that neither Party is representing or warranting in any way as to the accuracy or sufficiency of any Information exchanged or disclosed under this Agreement.

(b) Neither DTE Energy nor DT Midstream shall have any Liability to the other Party in the event that any Information exchanged or provided pursuant to this Agreement that is an estimate or forecast, or that is based on an estimate or forecast, is found to be inaccurate in the absence of willful misconduct by the providing Person. Neither DTE Energy nor DT Midstream shall have any Liability to the other Party if any Information is destroyed after reasonable best efforts by DT Midstream or DTE Energy, as applicable, to comply with the provisions of Section 7.04.

SECTION 7.07. Production of Witnesses; Records; Cooperation. (a) Without limiting any of the rights or obligations of the Parties pursuant to Section 7.01 or Section 7.04, after the Distribution Date and until the second anniversary thereof, except in the case of an Adversarial Action or threatened or contemplated Adversarial Action, each of DTE Energy and DT Midstream shall use their reasonable best efforts to make available, upon written request, (i) the former, current and future directors, officers, employees, other personnel and agents of the Persons in its respective Group (whether as witnesses or otherwise) and (ii) any books, records or other documents within its control or that it otherwise has the ability to make available, in each case, to the extent that such Person (giving consideration to business demands of such directors, officers, employees, other personnel and agents) or books, records or other documents may reasonably be required in connection with any Action, Commission comment or review or threatened or contemplated Action, Commission comment or review (including preparation for any such Action, Commission comment or review) in which either DTE Energy or DT Midstream or any Person or Persons in its Group, as applicable, may from time to time be involved, regardless of whether such Action, Commission comment or review or threatened or contemplated Action, Commission comment or review is a matter with respect to which indemnification may be sought hereunder. The requesting Party shall bear all reasonable out-of-pocket costs and expenses in connection therewith.

(b) Without limiting the foregoing, DTE Energy and DT Midstream shall use their reasonable best efforts to reasonably cooperate and consult with each other to the extent reasonably necessary with respect to any Actions or threatened or contemplated Actions (including in connection with preparation for any such Action), other than an Adversarial Action or threatened or contemplated Adversarial Action.

(c) The obligation of DTE Energy and DT Midstream to use their reasonable best efforts to make available former, current and future directors, officers, employees and other personnel and agents or provide witnesses and experts pursuant to this Section 7.07 is intended, other than in respect of an Adversarial Action or threatened or contemplated Adversarial Action, to be interpreted in a manner to facilitate cooperation and shall include the obligation to make

available employees and other officers without regard to whether such individual or the employer of such individual could assert a possible business conflict. Without limiting the foregoing, each of DTE Energy and DT Midstream agrees that neither it nor any Person or Persons in its respective Group will take any adverse action against any employee of its Group based on such employee’s provision of assistance or information to each other pursuant to this Section 7.07.

SECTION 7.08. Privileged Matters. (a) The Parties recognize that legal and other professional services that have been and will be provided prior to the Distribution (whether by outside counsel, in-house counsel or other legal professionals) have been and will be rendered for the collective benefit of each of the members of the DTE Energy Group and the DT Midstream Group, and that each of the members of the DTE Energy Group and the DT Midstream Group shall be deemed to be the client with respect to such services for the purposes of asserting all privileges which may be asserted under applicable Law in connection therewith. The Parties recognize that legal and other professional services will be provided following the Distribution, which services will be rendered solely for the benefit of the DTE Energy Group or the DT Midstream Group, as the case may be.

(b) The Parties agree as follows:

(i) DTE Energy shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any privileged Information that relates solely to the DTE Energy Business and not to the operations of the DT Midstream Business, whether or not the privileged Information is in the possession or under the control of any member of the DTE Energy Group or any member of the DT Midstream Group. DTE Energy shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any privileged Information that relates solely to any DTE Energy Assets or DTE Energy Liabilities and not any DT Midstream Assets or DT Midstream Liabilities in connection with any Actions that are now pending or may be asserted in the future, whether or not the privileged Information is in the possession or under the control of any member of the DTE Energy Group or any member of the DT Midstream Group;

(ii) DT Midstream shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any privileged Information that relates solely to the operations of the DT Midstream Business and not to the DTE Energy Business, whether or not the privileged Information is in the possession or under the control of any member of the DT Midstream Group or any member of the DTE Energy Group. DT Midstream shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any privileged Information that relates solely to any DT Midstream Assets or DT Midstream Liabilities and not any DTE Energy Assets or DTE Energy Liabilities in connection with any Actions that are now pending or may be asserted in the future, whether or not the privileged Information is in the possession or under the control of any member of the DT Midstream Group or any member of the DTE Energy Group; and

(iii) if the Parties do not agree as to whether certain information is privileged Information, then such Information shall be treated as privileged Information, and the Party that believes that such information is privileged Information shall be entitled to control the assertion or waiver of all privileges and immunities in connection with any such information until such time as it is finally judicially determined that such information is not privileged Information or unless the Parties otherwise agree.

(c) Subject to the remaining provisions of this Section 7.08, the Parties agree that DTE Energy shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities not allocated pursuant to Section 7.08(b) in connection with any Actions or threatened or contemplated Actions or other matters that involve both Parties (or one or more members of their respective Groups) and in respect of which both Parties have Liabilities under this Agreement. Upon the reasonable request of DTE Energy or DT Midstream, in connection with any Action or threatened or contemplated Action contemplated by this Article VII, other than any Adversarial Action or threatened or contemplated Adversarial Action, DTE Energy and DT Midstream will enter into a mutually acceptable common interest agreement to maintain to the extent practicable any applicable attorney-client privilege, work product immunity or similar privilege or immunity of any member of either Group.

(d) If any dispute arises between the Parties or any members of their respective Group regarding whether a privilege or immunity should be waived to protect or advance the interests of either Party or any member of their respective Groups, each Party agrees that it shall (i) negotiate with the other Party in good faith, (ii) endeavor to minimize any prejudice to the rights of the other Party and the members of its Group and (iii) not unreasonably withhold, delay or condition consent to any request for waiver by the other Party.

(e) Upon receipt by either Party, or by any member of its respective Group, of any subpoena, discovery or other request (or of written notice that it will or has received such subpoena, discovery or other request) that may reasonably be expected to result in the production or disclosure of privileged Information subject to a shared privilege or immunity or as to which the other Party has the sole right hereunder to assert a privilege or immunity, or if either Party obtains knowledge or becomes aware that any of its, or any member of its respective Group’s, current or former directors, officers, agents or employees have received any subpoena, discovery or other requests (or have received written notice that they will or have received such subpoena, discovery or other requests) that may reasonably be expected to result in the production or disclosure of such privileged Information, such Party shall promptly notify the other Party of the existence of any such subpoena, discovery or other request and shall provide the other Party a reasonable opportunity to review the privileged Information and to assert any rights it or they may have, under this Section 7.08 or otherwise, to prevent the production or disclosure of such privileged Information; provided that if such Party is prohibited by applicable Law from disclosing the existence of such subpoena, discovery or other request, such Party shall provide written notice of such related information for which disclosure is not prohibited by applicable Law and use reasonable best efforts to inform the other Party of any related information such Party reasonably determines is necessary or appropriate for the other Party to be informed of to enable the other Party to review the privileged Information and to assert its rights, under this Section 7.08 or otherwise, to prevent the production or disclosure of such privileged Information.

(f) The Parties agree that their respective rights to any access to Information, witnesses and other Persons, the furnishing of notices and documents and other cooperative efforts between the Parties contemplated by this Agreement, and the transfer of privileged Information between the Parties and members of their respective Groups pursuant to this Agreement, shall not be deemed a waiver of any privilege that has been or may be asserted under this Agreement or otherwise. The Parties further agree that (i) the exchange by one Party to the other Party of any Information that should not have been exchanged pursuant to the terms of Section 7.09 shall not be deemed to constitute a waiver of any privilege or immunity that has been or may be asserted under this Agreement or otherwise with respect to such privileged Information and (ii) the Party receiving such privileged Information shall promptly return such privileged Information to the Party who has the right to assert the privilege or immunity.

SECTION 7.09. Confidential Information. (a) Each of DTE Energy and DT Midstream, on behalf of itself and each Person in its respective Group, shall hold, and cause its respective directors, officers, employees, agents, accountants, subcontractors, counsel and other advisors and representatives to hold, in strict confidence, and not release or disclose, and protect with at least the same degree of care, but no less than a reasonable degree of care, that it applies to its own confidential and proprietary Information pursuant to policies in effect as of the Distribution Date, all Information concerning the other Group or its business that is either in its possession (including Information in its possession prior to the Distribution) or furnished by the other Group or its respective directors, officers, employees, agents, accountants, counsel and other advisors and representatives at any time pursuant to this Agreement, and shall not use any such Information other than for such purposes as shall be expressly permitted hereunder, except, in each case, to the extent that such Information is (i) in the public domain through no fault of any member of the DTE Energy Group or the DT Midstream Group, as applicable, or any of its respective directors, officers, employees, agents, accountants, counsel and other advisors and representatives, (ii) later lawfully acquired from other sources by any of DTE Energy, DT Midstream or its respective Group, employees, directors or agents, accountants, counsel and other advisors and representatives, as applicable, which sources are not themselves bound by a confidentiality obligation to the knowledge of any of DTE Energy, DT Midstream or Persons in its respective Group, as applicable, (iii) independently generated after the date hereof without reference to any proprietary or confidential Information of the DTE Energy Group or the DT Midstream Group, as applicable, or (iv) required to be disclosed by Law; provided, however, that the Person required by Law to disclose such Information gives the applicable Person prompt, and to the extent reasonably practicable and legally permissible, prior notice of such disclosure and an opportunity to contest such disclosure and shall use reasonable best efforts to cooperate, at the expense of the requesting Person, in seeking any reasonable protective arrangements requested by such Person. In the event that such appropriate protective order or other remedy is not obtained, the Person that is required to disclose such Information shall furnish, or cause to be furnished, only that portion of such Information that is required by Law to be disclosed and shall use reasonable best efforts to ensure that confidential treatment is accorded such Information. Notwithstanding the foregoing, each of DTE Energy and DT Midstream may release or disclose, or permit to be released or disclosed, any such Information concerning the other Group (x) to their respective directors, officers, employees, agents, accountants, counsel and other advisors and representatives who need to know such Information (who shall be advised of the obligations hereunder with respect to such Information) and (y) to any nationally recognized statistical rating organization as it reasonably deems necessary, solely for the purpose of obtaining a rating of

securities or other debt instruments upon normal terms and conditions; provided, however, that the Party whose Information is being disclosed or released to such rating organization must be promptly notified thereof by the disclosing Party.

(b) Without limiting the foregoing, when any Information concerning the other Group or its business is no longer needed for the purposes contemplated by this Agreement or any Ancillary Agreement, each of DTE Energy and DT Midstream, as applicable, will, promptly after the request of the other Party, either return all Information in a tangible form (including all copies thereof and all notes, extracts or summaries based thereon) or certify to the other Party, as applicable, that it has destroyed such Information, other than, in each case, any such Information electronically preserved or recorded within any computerized data storage device or component (including any hard-drive or database) pursuant to automatic or routine backup procedures generally accessible only by legal, IT or compliance personnel.

SECTION 7.10. Conflicts Waiver. Each of the Parties acknowledges, on behalf of itself and each other member of its Group, notwithstanding anything to the contrary contained herein, that DTE Energy has retained Cravath, Swaine & Moore LLP (the “Known Counsel”) to act as its counsel in connection with this Agreement, the Ancillary Agreements and the transactions contemplated hereby and thereby. DT Midstream hereby agrees on behalf of itself and each member of its Group that, notwithstanding anything to contrary contained herein, in the event that a dispute arises between or among (x) any member of the DT Midstream Group, any DT Midstream Indemnitee or any of their respective Affiliates, on the one hand, and (y) any member of the DTE Energy Group, any DTE Energy Indemnitee or any of their respective Affiliates, on the other hand, the Known Counsel may represent any member of the DTE Energy Group, any DTE Energy Indemnitee or any of their respective Affiliates in such dispute even though the interests of such Person may be directly adverse to any Person described in clause (x), and even though such Known Counsel may have represented a Person described in clause (x), in a matter substantially related to such dispute, or may be handling ongoing matters for a Person described in clause (x), and DT Midstream hereby waives, on behalf of itself and each other Person described in clause (x), as applicable, any conflict of interest in connection with such representation by such Known Counsel. Each of DT Midstream and DTE Energy, on behalf of itself and each other member of its Group, agrees to take, and to cause their respective then-Affiliates to take, all steps necessary to implement the intent of this Section 7.10.

ARTICLE VIII

Insurance

SECTION 8.01. Maintenance of Insurance. For the period beginning as of the date hereof and ending on the date immediately prior to the Distribution Date, DTE Energy shall (i) cause the members of the DT Midstream Group and their respective employees, officers and directors to continue to be covered as insured parties under DTE Energy’s policies of insurance in a manner which is no less favorable than the coverage provided for the DTE Energy Group and (ii) permit the members of the DT Midstream Group and their respective employees,

officers and directors to submit claims relating to, arising out of or resulting from facts, circumstances, events or matters that occurred prior to the Distribution Date to the extent permitted under such policies. With respect to any policies currently procured by DT Midstream for the sole benefit of the DT Midstream Group, DT Midstream shall continue to maintain such insurance coverage through the Distribution Date in a manner no less favorable than currently provided. Except as otherwise expressly permitted in this Article VIII, DTE Energy and DT Midstream acknowledge that, as of the date immediately prior to the Distribution Date, DTE Energy intends to take such action as it may deem necessary or desirable to remove the members of the DT Midstream Group and their respective employees, officers and directors as insured parties under any policy of insurance issued to any member of the DTE Energy Group by any insurance carrier effective as of the date immediately prior to the Distribution Date. The DT Midstream Group will not be entitled on or following the Distribution Date to make any claims for insurance thereunder to the extent such claims are based upon facts, circumstances, events or matters occurring on or after the Distribution Date or to the extent any claims are made pursuant to any DTE Energy claims-made policies on or after the Distribution Date. No member of the DTE Energy Group shall be deemed to have made any representation or warranty as to the availability of any coverage under any such insurance policy. Notwithstanding the foregoing, DTE Energy shall, and shall cause the other members of the DTE Energy Group to, use reasonable best efforts to take such actions as are necessary to cause all insurance policies of the DTE Energy Group that as of the date immediately prior to the Distribution Date provide coverage to or with respect to the members of the DT Midstream Group and their respective employees, officers and directors to continue to provide such coverage with respect to acts, omissions or events occurring prior to the Distribution Date in accordance with their terms as if the Distribution had not occurred; provided, however, that in no event shall DTE Energy be required to extend or maintain coverage under claims-made policies with respect to any claims first made against a member of the DT Midstream Group or first reported to the insurer on or after the Distribution Date.

SECTION 8.02. Claims Under DTE Energy Insurance Policies. (a) On and after the Distribution Date, the members of each of the DTE Energy Group and the DT Midstream Group shall have the right to assert DTE Energy Policy Pre-Separation Insurance Claims and the members of the DT Midstream Group shall have the right to participate with DTE Energy to resolve DTE Energy Policy Pre-Separation Insurance Claims under the applicable DTE Energy insurance policies up to the full extent of the applicable and available limits of liability of such policy. DTE Energy or DT Midstream, as the case may be, shall have primary control over those DTE Energy Policy Pre-Separation Insurance Claims for which the DTE Energy Group or the DT Midstream Group, respectively, bears the underlying loss, subject to the terms and conditions of the relevant policy of insurance governing such control; provided that only DTE Energy shall have the authority to settle or otherwise resolve any DTE Energy Policy Pre-Separation Insurance Claims with the applicable insurer(s), subject, in the case of any DTE Energy Policy Pre-Separation Insurance Claims for which the DT Midstream Group bears the underlying loss, to the prior written consent of DT Midstream (which consent shall not be unreasonably withheld, conditioned or delayed). If a member of the DT Midstream Group is unable to assert a DTE Energy Policy Pre-Separation Insurance Claim because it is no longer an “insured” or “additional insured” under a DTE Energy insurance policy, then DTE Energy shall, to the extent permitted by applicable Law and the terms of such insurance policy, assert such claim in its own name and deliver the Insurance Proceeds to DT Midstream.

(b) With respect to DTE Energy Policy Pre-Separation Insurance Claims, whether or not known or reported on or prior to the Distribution Date, DT Midstream shall, or shall cause the applicable member of the DT Midstream Group to, report such claims arising from the DT Midstream Business as soon as practicable to each of DTE Energy and the applicable insurer(s), and DT Midstream shall, or shall cause the applicable member of DT Midstream Group to, individually, and not jointly, assume and be responsible (including, upon the request of DTE Energy, by reimbursement to DTE Energy for amounts paid or payable by it) for the reimbursement liability (including any deductible, coinsurance or retention payment) related to its portion of the liability, unless otherwise agreed in writing by DTE Energy. Each of DTE Energy and DT Midstream shall, and shall cause each member of the DTE Energy Group and DT Midstream Group, respectively, to, cooperate and assist the applicable member of the DT Midstream Group and the DTE Energy Group, as applicable, with respect to such claims. The applicable member of the DT Midstream Group shall provide to DTE Energy any collateral (or a letter of credit the face value of which is an amount equal to the value of such collateral) in respect of the reimbursement obligations as may reasonably be requested by the insurers and, upon the request of DTE Energy, any other collateral required by the insurers in respect of insurance policies under which DTE Energy Policy Pre-Separation Insurance Claims may be recoverable based upon DTE Energy’s reasonable estimate of the proportion of the requested collateral attributable to claims that may be made by the DT Midstream Group. DTE Energy agrees that DTE Energy Policy Pre-Separation Insurance Claims of members of the DT Midstream Group shall receive the same priority as DTE Energy Policy Pre-Separation Insurance Claims of members of the DTE Energy Group and be treated equitably in all respects, including in connection with deductibles, retentions and coinsurance.

SECTION 8.03. Insurance Proceeds. Any Insurance Proceeds received by the DTE Energy Group for members of the DT Midstream Group or by the DT Midstream Group for members of the DTE Energy Group shall be for the benefit, respectively, of the DT Midstream Group and the DTE Energy Group, as applicable. Any Insurance Proceeds received for the benefit of both the DTE Energy Group and the DT Midstream Group shall be distributed pro rata based on the respective share of the underlying loss.

SECTION 8.04. Claims Not Reimbursed. DTE Energy shall not be liable to DT Midstream for claims, or portions of claims, not reimbursed by insurers under any policy for any reason, including coinsurance provisions, deductibles, quota share deductibles, self-insured retentions, bankruptcy or insolvency of any insurance carrier(s), policy limitations or restrictions (including exhaustion of limits), any coverage disputes, any failure to timely file a claim by any member of the DTE Energy Group or any member of the DT Midstream Group or any defect in such claim or its processing. In the event that insurable claims of both DTE Energy and DT Midstream (or the members of their respective Groups) exist relating to the same occurrence, the Parties shall jointly defend and waive any conflict of interest necessary to the conduct of the joint defense and shall not settle or compromise any such claim without the consent of the other (which consent shall not be unreasonably withheld, conditioned or delayed subject to the terms and conditions of the applicable insurance policy). Nothing in this Section 8.04 shall be construed to limit or otherwise alter in any way the obligations of the Parties, including those created by this Agreement, by operation of Law or otherwise.

SECTION 8.05. D&O Policies.

(a) On and after the Distribution Date, DTE Energy shall not, and shall cause the members of the DTE Energy Group not to, take any action that would limit the coverage of the individuals who acted as directors, officers or employees of DT Midstream (or members of the DT Midstream Group) prior to the Distribution Date under any directors and officers liability insurance policies or fiduciary liability insurance policies (collectively, “D&O Policies”) maintained by the members of the DTE Energy Group in respect of claims relating to a period prior to the Distribution Date. DTE Energy shall, and shall cause the members of the DTE Energy Group to, reasonably cooperate with the individuals who acted as directors, officers or employees of DT Midstream (or members of the DT Midstream Group) prior to the Distribution Date in their pursuit of any coverage claims under such D&O Policies which could inure to the benefit of such individuals. DTE Energy shall, and shall cause members of the DTE Energy Group to, allow DT Midstream and its agents and representatives, upon reasonable prior notice and during regular business hours, to examine and make copies of the relevant D&O Policies maintained by DTE Energy and members of the DTE Energy Group pursuant to this Section 8.05. DTE Energy shall provide, and shall cause other members of the DTE Energy Group to provide, such cooperation as is reasonably requested by DT Midstream in order for DT Midstream to have in effect on and after the Distribution Date such new D&O Policies as DT Midstream deems appropriate with respect to claims relating to a period on or after the Distribution Date.

(b) Except as provided in this Section 8.05, the DTE Energy Group may, at any time, without liability or obligation to the DT Midstream Group, amend, commute, terminate, buy-out, extinguish liability under or otherwise modify any “occurrence-based” insurance policy or “claims-made-based” insurance policy (and such claims will be subject to any such amendments, commutations, terminations, buy-outs, extinguishments and modifications); provided, however, that DTE Energy will immediately notify DT Midstream of any termination of any insurance policy.

SECTION 8.06. Insurance Cooperation. The Parties shall use reasonable best efforts to cooperate with respect to the various insurance matters contemplated by this Article VIII.

ARTICLE IX

Further Assurances and Additional Covenants

SECTION 9.01. Further Assurances. (a) In addition to the actions specifically provided for elsewhere in this Agreement, but subject to the express limitations of this Agreement and of the Ancillary Agreements, each of the Parties shall, subject to Section 5.03, use reasonable best efforts, prior to, on and after the Distribution Date, to take, or cause to be taken, all actions, and to do, or cause to be done, all things, reasonably necessary, proper or advisable under applicable Laws and agreements to consummate and make effective the transactions contemplated by this Agreement.

(b) Without limiting the foregoing, but subject to the express limitations of this Agreement and of the Ancillary Agreements, prior to, on and after the Distribution Date, each Party shall cooperate with the other Party, without any further consideration, but at the

expense of the requesting Party, (i) to execute and deliver, or use reasonable best efforts to execute and deliver, or cause to be executed and delivered all instruments, including any instruments of conveyance, assignment and transfer as such Party may reasonably be requested to execute and deliver by the other Party, (ii) to make, or cause to be made, all filings with, and to obtain, or cause to be obtained, all Consents of any Governmental Authority or any other Person under any permit, license, Contract, indenture or other instrument, (iii) to obtain, or cause to be obtained, any Governmental Approvals or other Consents required to effect the Spin-Off and (iv) to take, or cause to be taken, all such other actions as such Party may reasonably be requested to take by the other Party from time to time, consistent with the terms of this Agreement and the Ancillary Agreements, in order to effectuate the provisions and purposes of this Agreement, the Ancillary Agreements and any transfers of Assets or assignments and assumptions of Liabilities hereunder and thereunder and the other transactions contemplated hereby and thereby.

(c) On or prior to the Distribution Date, DTE Energy and DT Midstream, in their respective capacities as direct and indirect shareholders of their respective Subsidiaries, shall each ratify any actions that are reasonably necessary or desirable to be taken by DT Midstream or any other Subsidiary of DTE Energy, as the case may be, to effectuate the transactions contemplated by this Agreement.

(d) Prior to the Distribution, if either Party identifies any commercial or other service that is needed to ensure a smooth and orderly transition of its business in connection with the consummation of the transactions contemplated hereby, and that is not otherwise governed by the provisions of this Agreement or any Ancillary Agreement, the Parties will cooperate in good faith to determine whether there is a mutually acceptable arm’s-length basis on which the other Party will provide such service.

SECTION 9.02. Non-Solicit and No-Hire. (a) Except as set forth in Section 2.02 of the EMA, each Party covenants and agrees that, from the Distribution Date through the 24-month anniversary of the Distribution Date, (i) it shall not, and shall cause its respective Subsidiaries not to, directly or indirectly, employ, hire, enter into an agency or consulting relationship with, recruit or solicit for employment, or interfere with the employment of, any employee of the members of the other Group (“Restricted Employees”); provided that the foregoing restrictions shall not apply to (A) any Restricted Employee whose employment was involuntarily terminated by the applicable Party or its Affiliates, (B) any Restricted Employee who has not been employed by the applicable Party or any of its Subsidiaries for at least six months, (C) any Restricted Employee whose prospective employment is agreed to in writing and signed by the highest level human resources officer at both companies and (D) any Restricted Employee who responds to general solicitations not targeted at Restricted Employees (including through the use of recruiting firms not directed at Restricted Employees) or advertisement in any newspaper, magazine, trade publication, electronic medium or other media; and (ii) it shall use reasonable best efforts to inform each of its Group’s officers and managers, and any of its other employees with responsibility for recruitment or hiring of employees, of the restrictions set forth in this Section 9.02(a).

(b) If a final and non-appealable judicial determination is made that any provision of this Section 9.02 constitutes an unreasonable or otherwise unenforceable restriction

with respect to any particular jurisdiction, the provisions of this Section 9.02 will not be rendered void but will be deemed to be modified solely with respect to the applicable jurisdiction to the minimum extent necessary to remain in force and effect for the greatest period and to the greatest extent that such court determines constitutes a reasonable restriction under the circumstances.

ARTICLE X

SECTION 10.01. Termination. This Agreement may be terminated by DTE Energy at any time, in its sole discretion, prior to the Distribution.

SECTION 10.02. Effect of Termination. In the event of any termination of this Agreement prior to the Distribution, neither Party (nor any member of their Group or any of their respective directors or officers) shall have any Liability or further obligation to the other Party or any member of its Group under this Agreement or the Ancillary Agreements.

ARTICLE XI

Miscellaneous

SECTION 11.01. Counterparts; Entire Agreement; Corporate Power. (a) This Agreement may be executed in one or more counterparts, all of which counterparts shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each Party and delivered to the other Party. This Agreement may be executed by electronic or PDF signature and scanned and exchanged by electronic mail, and such electronic or PDF signature shall constitute an original for all purposes.

(b) This Agreement, the Ancillary Agreements and any Appendices, Exhibits and Schedules hereto and thereto contain the entire agreement between the Parties with respect to the subject matter hereof and supersede all previous agreements, negotiations, discussions, writings, understandings, commitments and conversations with respect to such subject matter, and there are no agreements or understandings between the Parties with respect to the subject matter hereof other than those set forth or referred to herein or therein.

(c) DTE Energy represents on behalf of itself and each other member of the DTE Energy Group, and DT Midstream represents on behalf of itself and each other member of the DT Midstream Group, as follows:

(i) each such Person has the requisite corporate or other power and authority and has taken all corporate or other action necessary in order to execute, deliver and perform each of this Agreement and each Ancillary Agreement to which it is a party and to consummate the transactions contemplated hereby and thereby; and

(ii) this Agreement and each Ancillary Agreement to which it is a party has been (or, in the case of any Ancillary Agreement, will be on or prior to the Distribution Date) duly executed and delivered by it and constitutes, or will constitute, a valid and binding agreement of it enforceable in accordance with the terms thereof.

SECTION 11.02. Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of Laws thereof. Each Party irrevocably consents to the exclusive jurisdiction, forum and venue of the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, any Delaware State court or the federal court sitting in the State of Delaware) over any and all claims, disputes, controversies or disagreements between the Parties or any of their respective Subsidiaries, Affiliates, successors and assigns under or related to this Agreement or any document executed pursuant to this Agreement or any of the transactions contemplated hereby or thereby, including their execution, performance or enforcement, whether in contract, tort or otherwise. Each of the Parties hereby agrees that it shall not assert, and shall hereby waive, any claim or right or defense that it is not subject to the jurisdiction of such courts, that the venue is improper, that the forum is inconvenient or any similar objection, claim or argument. Each Party agrees that a final judgment in any legal proceeding resolved in accordance with this Section 11.02 and Section 11.12 shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN CONNECTION WITH ANY LITIGATION ARISING OUT OF OR RELATING IN ANY WAY TO THIS AGREEMENT PROVIDED HEREUNDER.

SECTION 11.03. Assignability. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of Law or otherwise by either Party without the prior written consent of the other Party. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and permitted assigns. Notwithstanding the foregoing, either Party may assign this Agreement without consent of the other Party in connection with (a) a merger transaction in which such Party is not the surviving entity and the surviving entity acquires or assumes all or substantially all of such Party’s Assets or (b) the sale of all or substantially all of such Party’s Assets; provided, however, that the assignee expressly assumes in writing all of the obligations of the assigning Party under this Agreement, and the assigning Party provides written notice and evidence of such assignment and assumption to the non-assigning Party as promptly as reasonably practicable following the assignment. No assignment permitted by this Section 11.03 shall release the assigning Party from liability for the full performance of its obligations under this Agreement.

SECTION 11.04. Third-Party Beneficiaries. Except as expressly set forth in Section 7.10 and for the indemnification rights under this Agreement of any DTE Energy Indemnitee or DT Midstream Indemnitee in their respective capacities as such, (a) the provisions of this Agreement are solely for the benefit of the Parties hereto and are not intended to confer upon any Person except the Parties hereto any rights or remedies hereunder and (b) there are no third-party beneficiaries of this Agreement and this Agreement shall not provide any third Person with any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without reference to this Agreement.

Either Party may, by notice to the other Party, change the address and identity of the Person to which such notices and copies of such notices are to be given. Each Party agrees that nothing in this Agreement shall affect the other Party’s right to serve process in any other manner permitted by Law.

SECTION 11.06. Severability. If any provision of this Agreement or the application thereof to any Person or circumstance is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions hereof, or the application of such provision to Persons or circumstances or in jurisdictions other than those as to which it has been held invalid or unenforceable, shall remain in full force and effect and shall in no way be affected, impaired or invalidated thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either Party. Upon any such determination, any such provision, to the extent determined to be invalid, void or unenforceable, shall be deemed replaced by a provision that such court determines is valid and enforceable and that comes closest to expressing the intention of the invalid, void or unenforceable provision.

SECTION 11.07. Publicity. Each of DTE Energy and DT Midstream shall consult with the other, and shall, subject to the requirements of Section 7.09, provide the other Party the opportunity to review and comment upon, any press releases or other public statements in connection with the Spin-Off or any of the other transactions contemplated hereby and any filings with any Governmental Authority or national securities exchange with respect thereto, in each case prior to the issuance or filing thereof, as applicable (including the Information Statement, the Parties’ respective Current Reports on Form 8-K to be filed on the Distribution Date, the Parties’ respective Quarterly Reports on Form 10-Q filed with respect to the fiscal quarter during which the Distribution Date occurs, or if such quarter is the fourth fiscal quarter, the Parties’ respective Annual Reports on Form 10-K filed with respect to the fiscal year during which the Distribution Date occurs (each such Quarterly Report on Form 10-Q or Annual Report on Form 10-K, a “First Post-Distribution Report”)). Each Party’s obligations pursuant to this Section 11.07 shall terminate on the date on which such Party’s First Post-Distribution Report is filed with the Commission.

SECTION 11.08. Expenses. Except as expressly set forth in this Agreement or in any Ancillary Agreement, all third-party fees, costs and expenses paid or incurred in connection with the Spin-Off will be paid by the Party incurring such fees or expenses, whether or not the Distribution is consummated, or as otherwise agreed by the Parties. Notwithstanding the foregoing, DTE Energy and DT Midstream shall each bear the costs and expenses incurred or paid as of the Distribution Date in connection with the Spin-Off for the services and to the financial, legal, accounting and other advisors set forth below their respective names on Schedule XV.

SECTION 11.09. Headings. The article, section and paragraph headings contained in this Agreement, including in the table of contents of this Agreement, are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 11.10. Survival of Covenants. Except as expressly set forth in this Agreement, the covenants in this Agreement and the Liabilities for the breach of any obligations in this Agreement shall survive the Spin-Off and shall remain in full force and effect.

SECTION 11.11. Waivers of Default. No failure or delay of any Party (or the applicable member of its Group) in exercising any right or remedy under this Agreement or any Ancillary Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. Waiver by any Party of any default by the other Party of any provision of this Agreement shall not be deemed a waiver by the waiving Party of any subsequent or other default.

SECTION 11.12. Specific Performance. Subject to Section 5.03 and notwithstanding the procedures set forth in Article XI, in the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, the affected Party shall have the right to specific performance and injunctive or other equitable relief of its rights under this Agreement, in addition to any and all other rights and remedies at Law or in equity, and all such rights and remedies shall be cumulative. The other Party shall not oppose the granting of such relief on the basis that money damages are an adequate remedy. The Parties agree that the remedies at Law for any breach or threatened breach hereof, including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at Law would be adequate is waived. Any requirements for the securing or posting of any bond with such remedy are waived.

SECTION 11.13. No Admission of Liability. The allocation of Assets and Liabilities herein (including on the Schedules hereto) is solely for the purpose of allocating such Assets and Liabilities between DTE Energy and the other members of the DTE Energy Group, on one hand, and DT Midstream and the other members of the DT Midstream Group, on the other hand, and is not intended as an admission of liability or responsibility for any alleged Liabilities vis-à -vis any third party, including with respect to the Liabilities of any non-wholly owned subsidiary of DTE Energy or DT Midstream.

SECTION 11.14. Amendments. No provisions of this Agreement shall be deemed waived, amended, supplemented or modified by any Party, unless such waiver, amendment, supplement or modification is in writing and signed by the authorized representative of each Party.

SECTION 11.15. Interpretation. Words in the singular shall be held to include the plural and vice versa and words of one gender shall be held to include the other gender as the context requires. The terms “hereof”, “herein”, “herewith” and words of similar import, unless otherwise stated, shall be construed to refer to this Agreement as a whole (including all of the schedules hereto) and not to any particular provision of this Agreement. Article, Section or Schedule references are to the articles, sections and schedules of or to this Agreement unless otherwise specified. Any capitalized terms used in any Schedule to this Agreement or to any Ancillary Agreement but not otherwise defined therein shall have the meaning as defined in this Agreement or the Ancillary Agreement to which such Schedule is attached, as applicable. Any definition of or reference to any agreement, instrument or other document herein (including any reference herein to this Agreement) shall, unless otherwise stated, be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified from time to time (subject to any restrictions

on such amendments, supplements or modifications set forth herein). The word “including” and words of similar import when used in this Agreement shall mean “including, without limitation,” unless the context otherwise requires or unless otherwise specified. The word “or” shall not be exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” All references to “$” or dollar amounts are to the lawful currency of the United States of America. In the event that an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring either Party by virtue of the authorship of any provisions hereof.
