applicable Law, each of Labcorp and Fortrea shall, and shall cause the members of its Group to, treat for all Tax purposes any Delayed Labcorp Asset or Delayed Fortrea Asset, as the case may be, as an Asset owned by the Party entitled thereto under the Separation Agreement and any Delayed Fortrea Liability or Delayed Labcorp Liability, as the case may be, as a liability of the Party intended to be responsible for such liability under the Separation Agreement, in each case, not later than the Business Transfer Time, and responsibility for any Taxes attributable to such Asset shall be allocated between the Parties under this Agreement as if the legal transfer of ownership had not been delayed.

Section 2.06 Tax Refunds.

(a)Fortrea shall be entitled to all Refunds attributable to Taxes the liability for which is allocated to Fortrea pursuant to this Agreement (including pursuant to ARTICLE V). Labcorp shall be entitled to all Refunds attributable to Taxes the liability for which is allocated to Labcorp pursuant to this Agreement (including pursuant to ARTICLE V) and any other Refunds not described in the preceding sentence.

(b)Fortrea shall pay to Labcorp any Refund received by Fortrea or any member of the Fortrea Group that is allocable to Labcorp pursuant to this Section 2.06 no later than five (5) Business Days after the receipt of such Refund. Labcorp shall pay to Fortrea any Refund received by Labcorp or any member of the Labcorp Group that is allocable to Fortrea pursuant to this Section 2.06 no later than five (5) Business Days after the receipt of such Refund. For purposes of this Section 2.06, any Refund that arises as a result of an offset, credit, or other similar benefit in respect of Taxes other than a receipt of cash shall be deemed to be received on the earlier of (i) the date on which a Tax Return is filed claiming such offset, credit, or other similar benefit, and (ii) the date on which payment of the Tax which would have otherwise been paid absent such offset, credit, or other similar benefit is due (as determined by Labcorp in its sole and absolute discretion without taking into account any applicable extensions). Notwithstanding anything in this Section 2.06(b) to the contrary, any Refund of less than $50,000 treated as received pursuant to this Section 2.06(b) by Labcorp or any member of the Labcorp Group, on the one hand, or Fortrea or any member of the Fortrea Group, on the other hand, and that is owed to the other Party pursuant to this Section 2.06, may be aggregated with other Refunds received in the same calendar quarter and paid over to the other Party within thirty (30) days after the end of such calendar quarter.

Section 2.07 Tax Benefits. If Labcorp determines, in its sole and absolute discretion, that (i) one Party is responsible for a Tax pursuant to this Agreement or any other Transaction Document or under applicable Law, and (ii) the other Party is entitled to a Tax Benefit relating to such Tax (including any Tax basis step-up realized by any member of the Fortrea Group pursuant to the Transactions), then the Party entitled to such Tax Benefit shall pay to the Party responsible for such Tax the amount of the Tax Benefit, as determined pursuant to Section 2.07 and Section 2.08.

Section 2.08 Determination of Taxes, Refunds and Tax Benefits. The amount of any Taxes, any Refunds attributable to Taxes for which Labcorp or Fortrea, respectively,

is responsible pursuant to this Agreement, or the amount of any Tax Benefit, in each case, attributable to one or more items of income, gain, loss, deduction or credit (or equivalent items in the case of non-income Taxes) (the “relevant items”) shall be based on the increase or decrease in the amount of cash Taxes for which such Party is liable when measured by including such relevant items in a computation of Tax compared to excluding such relevant items from the computation of Tax, in each case as determined by Labcorp in its sole and absolute discretion, which may include making simplifying assumptions concerning the computation of Tax, including that the relevant Party be deemed to recognize all other items of income, gain, loss, deduction or credit (or equivalent items) before recognizing such relevant items; provided, that, if there is no increase or decrease in the amount of cash Taxes for which a Party is liable in the taxable period when first measured, the Parties shall thereafter make payments to one another at the end of each subsequent taxable period to reflect any increase or decrease in the amount of cash Taxes recognized in such subsequent taxable period; provided, further, that notwithstanding anything in this Section 2.08 to the contrary, Labcorp shall not be responsible for any non-U.S. Taxes of the Fortrea Group to the extent Fortrea has Tax Attributes attributable to the Labcorp Business that are available to offset such Tax, as determined by Labcorp in its sole and absolute discretion.

Section 2.09 Prior Agreements. Except as set forth in this Agreement and in consideration of the mutual indemnities and other obligations of this Agreement, any and all prior Tax sharing or allocation agreements or practices between any member of the Labcorp Group, on the one hand, and any member of the Fortrea Group, on the other, shall be terminated with respect to the Fortrea Group and the Labcorp Group as of the Distribution Date, and no member of either the Fortrea Group or the Labcorp Group shall have any continuing rights or obligations to any member of the other Group under any such agreement or practice, and the Parties shall reasonably cooperate to achieve this result.

Fortrea shall prepare and file when due (taking into account any applicable extensions), or shall cause to be so prepared and filed, all Tax Returns, including any amended Tax Returns, required to be filed by or with respect to members of the Fortrea Group other than those Tax Returns which Labcorp is required to prepare and file under Section 3.01.

Section 3.03 Right To Review Tax Returns. To the extent that the positions taken on any Tax Return required to be prepared and filed by any Party (or an Affiliate thereof) pursuant to Section 3.01 or Section 3.02 (the “Preparing Party”) would reasonably be expected to materially adversely affect the Tax position of the other Party (or Affiliate

thereof) or, in the case of any Fortrea Separate Return, to the extent that such Tax Return reports the treatment of any of the Transactions (the “Reviewing Party”), the Preparing Party shall (a) prepare the portion of such Tax Return that relates to the business of the Reviewing Party (the Labcorp Business or the Fortrea Business, as the case may be) or, in the case of any Fortrea Separate Return, that reports the treatment of any of the Transactions, (b) provide a draft of such portion of such Tax Return to the Reviewing Party for its review and comment at least thirty (30) days prior to the Due Date, and (c) modify such portion of such Tax Return before filing to include the reasonable comments of the Reviewing Party that are received at least five (5) days prior to the Due Date. For the avoidance of doubt, the Preparing Party shall, to the extent applicable, (i) report any of the Transactions the results of which are listed on such Tax Return in a manner consistent with the Intended Tax Treatment, and (ii) prepare any transfer pricing documentation required to be prepared with respect to such Tax Return, and the Reviewing Party shall be entitled to review and comment on any such transfer pricing documentation in a manner consistent herewith.

If an amended state or local Separate Return for which Fortrea is responsible under this ARTICLE III is required to be filed as a result of an amendment made in connection with an audit adjustment to a Joint Return filed for Federal Income Tax purposes, the Parties shall cooperate to ensure that such amended Separate Return can be prepared and filed in a manner that preserves confidential information, including through the use of third-party preparers.

Section 3.05 Tax Reporting Practices. Except as provided in Section 3.06, with respect to any Tax Return for any taxable period that begins on or before the second anniversary of the Distribution Date with respect to which Fortrea is the Responsible Party, such Tax Return shall be prepared in accordance with practices, accounting methods, elections, conventions, transfer pricing and Tax positions used with respect to the Tax Return in question for periods prior to the Distribution (“Past Practices”), and, in the case of any item the treatment of which is not addressed by Past Practices, in accordance with generally acceptable Tax accounting practices; provided, however, that Fortrea will not be required to follow Past Practices with either the written consent of Labcorp (such consent to be exercised in Labcorp’s sole and absolute discretion) or upon delivery to Labcorp of a “more likely than not” (or stronger) level opinion from a Tax Advisor that reporting in accordance with Past Practices is not correct. For the avoidance of doubt, the Parties acknowledge and agree that the tax reporting of the Transactions shall be governed by Section 3.06.

Section 3.06 Reporting of the Transactions.

In connection with the Transactions, Labcorp shall make one or more protective elections under Section 336(e) of the Code and the Treasury Regulations promulgated thereunder (and any corresponding or analogous provisions of state and local Tax Law) with respect to Fortrea and each other member of the Fortrea Group that is a domestic corporation for U.S. federal income tax purposes (a “Section 336(e) Election”). In connection therewith:

(a)Labcorp, Fortrea, and their respective Affiliates shall cooperate in making the Section 336(e) Elections, including by filing any statements, amending any Tax Returns, or taking such other actions as are necessary, in Labcorp’s sole and absolute discretion, to carry out the Section 336(e) Elections;

(b)if the Distribution fails to qualify (in whole or in part) for the Intended Tax Treatment, and Fortrea or any member of the Fortrea Group realizes an increase in Tax basis as a result of a Section 336(e) Election (a “Section 336(e) Tax Basis”), then the cash Tax savings realized by Fortrea and each member of the Fortrea Group as a result of such Section 336(e) Tax Basis shall be shared between Labcorp and Fortrea in the same proportion as the Taxes giving rise to such Section 336(e) Tax Basis were borne by Labcorp and Fortrea (after giving effect to the indemnification obligations in this Agreement); and

(c)to the extent any Section 336(e) Election becomes effective, each Party agrees not to take any position (and to cause each of its Affiliates not to take any position) that is inconsistent with such Section 336(e) Election on any Tax Return, in connection with any Tax Contest, or otherwise, except as may be required by a Final Determination.

Section 3.08 Initial Tax Payment Procedures.

(a)With respect to any Tax Return required to be filed pursuant to this Agreement, the Responsible Party shall remit or cause to be remitted to the applicable Taxing Authority in a timely manner any Taxes due in respect of any such Tax Return.

Business Days prior to the Due Date for such payment and thirty (30) Business Days after the receipt of such notice; provided, that, if any amount due to the Responsible Party cannot be calculated with accuracy prior to the applicable Due Date, the Responsible Party’s notice shall set forth, and the Party that is not the Responsible Party shall pay, a reasonable estimate of such amount to the Responsible Party at such time, and shall pay any difference between the amount finally determined to be the amount due and the estimated amount within thirty (30) Business Days of receipt of written notice from the Responsible Party setting forth in reasonably sufficient detail the calculation of such final determination.

(c)With respect to any estimated Taxes, the Party that is or will be the Responsible Party with respect to any Tax Return that will reflect (or otherwise give credit for) such estimated Taxes shall remit or cause to be remitted to the applicable Taxing Authority in a timely manner any estimated Taxes due. In the case of any estimated Taxes for which the Party that is not the Responsible Party is obligated pursuant to this Agreement to pay all or a portion of the Taxes that will be reported as due on any Tax Return that will reflect (or otherwise give credit for) such estimated Taxes, the Responsible Party shall notify the other Party, in writing, of its obligation to pay such estimated Taxes and, in reasonably sufficient detail, its calculation of the amount due by such other Party, and the Party receiving such notice shall pay such amount to the Responsible Party upon the later of thirty (30) Business Days prior to the Due Date for such payment and thirty (30) Business Days after the receipt of such notice.

(d)Receipt of consent by Fortrea or another member of the Fortrea Group from Labcorp pursuant to the provisions of this Section 3.09 shall not limit or modify Fortrea’s continuing indemnification obligations pursuant to ARTICLE V.

(B)(1) reasonably in advance of the submission of any request for any Post-Distribution Ruling provide Fortrea with a draft copy thereof, (2) consider in good faith any written comments submitted by Fortrea with respect to such draft copy, and (3) provide Fortrea with a final copy of such Post-Distribution Ruling, and (C) provide Fortrea with notice reasonably in advance of, and Fortrea shall have the right to attend, any formally scheduled meetings with the IRS (subject to the approval of the IRS) that relate to such Post-Distribution Ruling. Neither Fortrea nor any of its Affiliates shall seek any guidance from the IRS or any other Taxing Authority (whether written, oral or otherwise) at any time concerning the Transactions (including the impact of any transaction on the Transactions).

(a)Except as otherwise provided in this Agreement, if either Party (the “Indemnitee”) is required to pay to a Taxing Authority a Tax or to another Person a payment in respect of Taxes, Tax-Related Costs and Expenses or Tax-Related Losses for which the other Party (the “Indemnifying Party”) is liable under this Agreement, including as the result of a Final Determination, the Indemnitee shall notify the Indemnifying Party, in writing, of its obligation to pay such Taxes, Tax-Related Costs and Expenses or Tax-Related Losses and, in reasonably sufficient detail, its calculation of the amount due by such Indemnifying Party to the Indemnitee. The Indemnifying Party shall pay such amount, including any Tax-Related Costs and Expenses or Tax-Related Losses, to the Indemnitee no later than the later of (i) five (5) Business Days prior to the Due Date for such payment to the applicable Taxing Authority, and (ii) five (5) Business Days after the receipt of notice from the other Party.

(b)If, as a result of any change or redetermination, any amount previously allocated to and borne by one Party pursuant to the provisions of ARTICLE II is thereafter allocated to the other Party, then, no later than five (5) Business Days after such change or redetermination, such other Party shall pay to the first Party the amount previously borne by the first Party which is allocated to such other Party as a result of such change or redetermination.

(c)If a Party incurs a Tax liability as a result of its receipt of a payment pursuant to this Agreement or the Separation Agreement, such payment shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all Taxes payable with respect to the receipt thereof (but taking into account all correlative Tax Benefits resulting from the payment of such Taxes), shall equal the

amount of the payment which the Party receiving such payment would otherwise be entitled to receive.

Section 5.03 Payment Mechanics.

(a)All payments under this Agreement shall be made by Labcorp directly to Fortrea and by Fortrea directly to Labcorp; provided, however, that, if the Parties mutually agree with respect to any such payment, any member of the Labcorp Group, on the one hand, may make such payment to any member of the Fortrea Group, on the other hand, and vice versa. All indemnification payments shall be treated for U.S. federal, state and local income tax purposes in the manner described in Section 5.04.

(b)In the case of any payment of Taxes made by a Responsible Party or Indemnitee pursuant to this Agreement for which such Responsible Party or Indemnitee, as the case may be, has received a payment from the other Party, such Responsible Party or Indemnitee shall provide to the other Party a copy of any official government receipt received with respect to the payment of such Taxes to the applicable Taxing Authority (or, if no such official governmental receipts are available, executed bank payment forms or other reasonable evidence of payment).

Section 5.04 Treatment of Payments. Except as expressly provided to the contrary in this Agreement or in the Separation Agreement, the Parties agree that any payment made between the Parties pursuant to this Agreement or the Separation Agreement shall, to the extent permitted by Law, be treated for U.S. federal, state and local income tax purposes as either (i) a non-taxable contribution by Labcorp to Fortrea, or (ii) a distribution by Fortrea to Labcorp, and, with respect to any payment made between the Parties after the Distribution pursuant to this Agreement or the Separation Agreement, such payment shall be treated as having been made immediately prior to the Distribution. Notwithstanding the foregoing, the Parties agree to treat for all Tax purposes any such payment which, pursuant to the proviso of Section 5.03(a), is to be made or received by a Subsidiary of a Party as made through one or more deemed distributions or deemed contributions, as the case may be.

ARTICLE VI.

TAX CONTESTS

Section 6.01 Notice. Each Party shall notify the other Party in writing within thirty (30) days after receipt by such Party or any member of its Group of a written communication from any Taxing Authority with respect to any pending or threatened audit, examination, claim, dispute, suit, action, proposed assessment or other proceeding (a “Tax Contest”) concerning any Taxes for which the other Party may be liable pursuant to this Agreement. A failure by an Indemnitee to give notice as provided in this Section 6.01 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement, except to the extent that such failure results in actual increased costs or actual prejudice to the other Party. For the avoidance of doubt, the obligations of the Parties to provide notice during the pendency of any Tax Context are set forth in Section 6.05, and the rights of a Non-Controlling Party to receive notice with

respect to the conduct of a Tax Contest in which such Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party are set forth in Section 6.07.

Section 6.02 Separate Returns.

(a)Except as otherwise provided in this Article VI, in the case of any Tax Contest with respect to any Separate Return, the Party having the liability for the Tax pursuant to ARTICLE II shall have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle, or agree to any deficiency, claim, or adjustment proposed, asserted, or assessed in connection with or as a result of such Tax Contest.

(b)In the case of any Tax Contest with respect to any Fortrea Separate Return, Fortrea shall not take any position in such Tax Contest inconsistent with any position taken by Labcorp on any Tax Return unless and until there has been a Final Determination that such latter position is not correct; provided, that Labcorp shall have the right to participate, at its own expense, in such Tax Contest, and Fortrea shall not resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted or assessed with respect to such Tax Contest without the written consent of Labcorp (such consent to be exercised in Labcorp’s sole and absolute discretion). For the avoidance of doubt, a Tax Contest with respect to a Fortrea Separate Return that is a Distribution-Related Tax Contest shall be governed by Section 6.04.

Section 6.03 Joint Returns. In the case of any Tax Contest with respect to any Joint Return, Labcorp shall have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle, or agree to any deficiency, claim, or adjustment proposed, asserted, or assessed in connection with or as a result of such Tax Contest.

Section 6.04 Distribution-Related Tax Contests. Notwithstanding anything to the contrary in Section 6.02 or Section 6.03, in the case of any Distribution-Related Tax Contest, Labcorp shall have the sole and absolute responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle or agree to any deficiency, claim or adjustment proposed, asserted, or assessed in connection with or as a result of such Tax Contest; provided, that, to the extent any Distribution-Related Tax Contest relates to a Fortrea Separate Return in respect of a taxable period beginning after the Distribution Date, such responsibilities and rights of Labcorp shall be limited to the portion of such Distribution-Related Tax Contest related to the Intended Tax Treatment of the Transactions or the amount of Taxes imposed in respect of any of the Transactions. Notwithstanding anything to the contrary in Section 6.06, the final determination of the positions taken, including with respect to settlement or other disposition, in any Distribution-Related Tax Contest (taking into account the proviso to the first sentence of this Section 6.04) shall be made in the sole and absolute discretion

of Labcorp and shall be final and not subject to the dispute resolution provisions in ARTICLE IX of this Agreement or ARTICLE V of the Separation Agreement.

Section 6.05 Obligation of Continued Notice. During the pendency of any Tax Contest, each of the Parties shall provide prompt notice to the other Party of any written communication received by the first Party or a member of its respective Group from a Taxing Authority regarding any Tax Contest for which the first Party is indemnified by the other Party hereunder or for which the first Party may be required to indemnify the other Party hereunder. Such notice shall include copies of the pertinent portion of any written communication from a Taxing Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any other documents received from any Taxing Authority in respect of any such matters. Such notice shall be provided in a reasonably timely fashion; provided, however, that, in the event that timely notice is not provided, a Party shall be relieved of its obligation to indemnify the other Party only to the extent that such delay results in actual increased costs or actual prejudice to such other Party.

Section 6.06 Tax Contest Rights. Unless waived by the Parties in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement, (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all material actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest, (ii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Taxing Authority or judicial authority in connection with such potential adjustment in such Tax Contest, and (iii) the Controlling Party shall defend such Tax Contest diligently and in good faith. The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability or obligation which it may have to the Controlling Party under this Agreement, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party.

Section 6.07 Consistent Treatment. Unless and until there has been a Final Determination to the contrary, each Party agrees not to take any position on any Tax Return, in connection with any Tax Contest, or otherwise that is inconsistent with (i) the treatment of payments between the Labcorp Group and the Fortrea Group as set forth in Section 5.04, (ii) the Tax Materials, or (iii) the Intended Tax Treatment of the Transactions.

Section 6.08 Costs and Expenses. Except to the extent provided otherwise in this Agreement, the Party to which the Tax liability related to a Tax Contest is (or would be) allocated, as determined by Labcorp in its sole and absolute discretion, shall be responsible for all accounting, legal and other professional fees, and court costs incurred in connection with such Tax Contest, as well as any other out-of-pocket costs

incurred in connection with such Tax Contest, regardless of which Party is responsible for the conduct of such Tax Contest; provided, that, in the event such Tax liability is allocated to both Parties, such costs shall be allocated to the Parties in such manner as the Labcorp determines in its sole and absolute discretion.

ARTICLE VII.

COOPERATION

Section 7.01 General.

(a)Each Party shall fully cooperate, and shall cause all members of such Party’s Group to fully cooperate, with all reasonable requests in writing from the other Party, or from an agent, representative, or advisor of such Party, in connection with the preparation and filing of any Tax Return or claim for Refund, the conduct of any Tax Contest (including fulfilling information requests from any Taxing Authority), and the calculation of any amount required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of either Party or any member of its Group covered by this Agreement or otherwise relating to the Fortrea Business for any Pre-Distribution Period or the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation with respect to a Tax Matter shall include, without limitation:

(i)the provision of any Tax Returns of either Party or any member of its Group, together with books, records (including information regarding ownership and Tax basis of property), and other information relating thereto, including accompanying schedules, related work papers, and any documents relating to rulings or other determinations by Taxing Authorities;

(ii)the execution of any document (including any power of attorney) reasonably requested in connection with any Tax Contest of either Party or any member of its Group, or the filing of a Tax Return or a Refund claim of either Party or any member of its Group; and

(iii)the use of the Party’s commercially reasonable efforts to obtain any other documentation reasonably requested in connection with a Tax Matter.

(b)In connection with any Tax Matter, each Party shall make its employees and facilities available, without charge, on a reasonable and mutually convenient basis in a manner that does not interfere with the ordinary business operations of such Party. Any information or documents provided under this Section 7.01 shall be kept confidential by the Party receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any Tax Contest. Notwithstanding anything to the contrary in this Agreement or any other agreement, (i) no Party or any of its Affiliates shall be required to provide another Party or any Affiliate thereof or any other Person access to (or copies of) any documents or other information (including with respect to the proceedings of any Tax Contest) other than documents or other information that reasonably relate to the

Taxes (including any Taxes for which the first Party is liable under this Agreement), business or assets of the first Party or any of its Affiliates or that are necessary to prepare Tax Returns for which the first Party is responsible for preparing in accordance with the terms of this Agreement, (ii) in no event shall any Party or any of its Affiliates be required to provide another Party, any of its Affiliates or any other Person access to (or copies of) any documents or other information if such action could reasonably be expected to result in the waiver of any Privilege, and, for the avoidance of doubt, Section 3.06 of the Separation Agreement shall apply with respect to matters of Privilege, and (iii) Labcorp shall not be required to provide to Fortrea any Tax Returns that are filed on an affiliated, consolidated, combined, unitary or other group basis. In addition, in the event that a Party determines that the provision of any information to another Party or any of its Affiliates could be commercially detrimental, violate any Law or agreement or waive any Privilege, the first Party shall use reasonable best efforts to permit compliance with its obligations under this Section 7.01 in a manner that avoids any such harm or consequence. The Party seeking access to documents, records or other information of the other Party under this Section 7.01 shall bear all out-of-pocket costs and expenses associated with such access, including any professional fees.

ARTICLE VIII.

RETENTION OF RECORDS

Section 8.01 Retention of Records. For so long as the contents thereof may become material in the administration of any matter under applicable Law, but in any event until the later of (i) sixty (60) days after the expiration of any applicable statutes of limitation (including any waivers or extensions thereof), and (ii) seven (7) years after the Distribution Date, the Parties shall retain records, documents, accounting data, and other information (including computer data) necessary for the preparation and filing of all Tax Returns (collectively, “Tax Records”) in respect of Taxes of any member of either the Labcorp Group or the Fortrea Group for any Pre-Distribution Period or Straddle Period or for any Tax Contests relating to such Tax Returns or otherwise affecting Taxes covered by this Agreement. At any time when the Labcorp Group proposes to destroy any Tax Records that pertain to Fortrea, Labcorp shall first notify Fortrea in writing and offer the Fortrea Group the opportunity to receive such records or documents proposed to be destroyed. At any time when the Fortrea Group proposes to destroy any Tax Records, ▇▇▇▇▇▇▇ shall first notify Labcorp in writing and offer the Labcorp Group the opportunity to receive such records or documents proposed to be destroyed. The Parties will notify each other in writing of any waivers or extensions of the applicable statute of limitations that may affect the period for which the foregoing records or other documents must be retained. The Party requesting receipt of any records or documents under this Section 8.01 shall bear all out-of-pocket costs and expenses associated therewith.

ARTICLE IX.

DISPUTE RESOLUTION

Section 9.01 Dispute Resolution. Subject to Section 9.03, Section 9.04 and Section 9.05, this Section 9.01 shall govern the resolution of any dispute between the Parties as to any matter covered by this Agreement that relates to the interpretation of Tax Law, as determined by Labcorp in its sole and absolute discretion (a “Tax Advisor Dispute”). The Party raising the Tax Advisor Dispute shall give prompt written notice of the Tax Advisor Dispute (a “Tax Advisor Dispute Notice”), and the tax directors of the Parties (or such other individuals designated by the respective general counsels) and/or the executive officers designated by the Parties shall negotiate for a reasonable period of time to settle such Tax Advisor Dispute; provided, that such reasonable period shall not, unless otherwise agreed by the Parties in writing, exceed thirty (30) days (the “Negotiation Period”) from the time of receipt of the Tax Advisor Dispute Notice; provided, further, that (x) the Parties shall not assert the defenses of statute of limitations, laches or any other defense, in each case, based on the passage of time during the Negotiation Period, and (y) any contractual time period or deadline under this Agreement relating to such Tax Advisor Dispute occurring after the Tax Advisor Dispute Notice is received shall not be deemed to have passed until the procedures described in this Section 9.01 have been resolved. If the Tax Advisor Dispute has not been resolved for any reason after the Negotiation Period, Labcorp shall, in its sole and absolute discretion, appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm shall make all determinations with respect to the Tax Advisor Dispute based solely on representations made by Labcorp, Fortrea, and their respective representatives, and not by independent review, and shall be required to make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve any Tax Advisor Dispute no later than thirty (30) days after the submission of such dispute to the Accounting Firm, but in no event later than the Due Date for the payment of Taxes or the filing of the relevant Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all Tax Advisor Disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the Past Practices of Labcorp and its Subsidiaries, except as otherwise required by applicable Law. The Parties shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be borne equally by the Parties, and the Parties agree to waive any objection to the naming of the Accounting Firm or the determination of the Accounting Firm based on actual or alleged conflicts of interest.

Section 9.02 Legal Disputes. Subject to Section 9.01, Section 9.03, Section 9.04 and Section 9.05, in the event of any other claim, controversy, demand or request for relief of any kind arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity or breach of this Agreement or otherwise arising

out of or related to this Agreement (a “Dispute”), then the Party raising the Dispute shall give prompt written notice of the Dispute, and the Dispute shall be resolved in accordance with the procedures contained in Article V of the Separation Agreement. For the avoidance of doubt, no matter or dispute addressed by Section 9.01 shall also be subject to this Section 9.02 or to Article V of the Separation Agreement.

Section 9.03 Injunctive Relief. Nothing in this ARTICLE IX shall prevent Labcorp from seeking injunctive relief to enforce the procedures provided for in Section 9.01 if any delay resulting from the efforts to resolve the Tax Advisor Dispute through the Accounting Firm could result in serious and irreparable injury to Labcorp. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, Labcorp and Fortrea are the only members of their respective Groups entitled to commence a dispute resolution procedure under this Agreement, and each of Labcorp and Fortrea will cause its respective Group members not to commence any dispute resolution procedure other than through Labcorp or Fortrea, as applicable, as provided in this ARTICLE IX.

Section 9.04 Specific Performance. Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, in the event of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, Labcorp shall have the right, without first pursuing the procedures provided in Section 9.01, to specific performance, declaratory relief and injunctive or other equitable relief (on a permanent, emergency, temporary, preliminary or interim basis) 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. Fortrea shall not oppose the granting of such relief on the basis that money damages are an adequate remedy. ▇▇▇▇▇▇▇ agrees that the remedies at Law for any breach or threatened breach hereof, including monetary damages, are inadequate compensation for any loss, and waives any defense in any action by Labcorp for specific performance that a remedy at Law would be adequate. Fortrea also waives any requirements that Labcorp secure or post any bond or similar security with respect to such remedy.

Section 9.05 Venue for Injunctive Relief and Specific Performance Claims by Labcorp. Notwithstanding anything to the contrary in this Agreement or the Separation Agreement (or any other Transaction Document), Labcorp may bring any claim for specific performance, declaratory relief and injunctive or other equitable relief (on a permanent, emergency, temporary, preliminary or interim basis) under Section 9.03 or Section 9.04 of this Agreement (a “Chosen Court Claim”) either (a) pursuant to the procedures contained in Article V of the Separation Agreement or (b) at Labcorp’s sole and absolute discretion, in the Delaware Court of Chancery (or, if the Delaware Court of Chancery shall be unavailable, any Delaware State court or the federal court sitting in the State of Delaware) (the “Chosen Courts”). Fortrea irrevocably consents and agrees, on behalf of itself and each Fortrea Group member, to the jurisdiction, forum and venue of the Chosen Courts for a Chosen Court Claim, and 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 the Chosen Courts, that the venue is improper, that the forum is inconvenient, that the

Chosen Court Claim should instead be arbitrated by agreement of Labcorp or operation of law, or any similar objection, claim or argument.

ARTICLE X.
