(b) Company General Rule. Except as provided in Section 3.04(c), with respect to any Tax Return for a Tax Period that begins on or before the date that is two (2) years following the Distribution Date that the Company has the obligation and right to prepare and file, or cause to be prepared and filed, under Section 3.02, such Tax Return shall be prepared in accordance with past practices, accounting methods, elections or conventions (“Past Practices”) used with respect to the Tax Returns in question (unless (i) the Company reasonably determines, upon advice from counsel, that there is no reasonable basis for the use of such Past Practices or (ii) there is no adverse effect to Lilly, as determined in Lilly’s reasonable discretion), and to the extent any items are not covered by Past Practices (or in the event that (i) the Company reasonably determines, upon advice from counsel, that there is no reasonable basis for the use of such Past Practices or (ii) there is no adverse effect to Lilly, as determined in Lilly’s reasonable discretion), in accordance with reasonable Tax accounting practices selected by the Company.

of state and local Law) in connection with the Distribution with respect to the Company and each other member of the Company Group that is a domestic corporation for U.S. federal Income Tax purposes (a “Section 336(e) Election”). If Lilly determines that a Section 336(e) Election would be beneficial:

(i) Lilly, the Company and their respective Affiliates shall cooperate in making the Section 336(e) Election, including by filing any statements, amending any Tax Returns or taking such other actions reasonably necessary to carry out the Section 336(e) Election;

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

(iii) to the extent the 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 the 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.

(e) Exception Where Required by a Final Determination.

(a) General. The Responsible Party with respect to any material Tax Return shall make the portion of such Tax Return and related workpapers which are relevant to the determination of the other Party’s rights or obligations under this Agreement available for review by the other Party, if requested, to the extent (i) such Tax Return relates to Taxes for which the requesting Party would reasonably be expected to be liable, (ii) the requesting Party would reasonably be expected to be liable in whole or in part for any additional Taxes owing as a result of adjustments to the amount of the Taxes reported on such Tax Return, (iii) such Tax Return relates to Taxes for which the requesting Party would reasonably be expected to have a claim for Tax Benefits under this Agreement, or (iv) the requesting Party reasonably determines that it must inspect such Tax Return to confirm compliance with the terms of this Agreement. The Responsible Party shall (i) use its reasonable best efforts to make such portion of such Tax

Return available for review as required under this paragraph sufficiently in advance of the due date for filing of such Tax Return to provide the requesting Party with a meaningful opportunity to analyze and comment on such Tax Return and (ii) use reasonable efforts to have such Tax Return modified before filing to reflect reasonable comments of the requesting Party, taking into account the person responsible for payment of the Tax (if any) reported on such Tax Return and whether the amount of Tax liability allocable to the requesting Party with respect to such Tax Return is material. The Parties shall attempt in good faith to resolve any issues arising out of the review of such Tax Return.

(b) Material Tax Returns. For purposes of Section 3.06(a), a Tax Return is “material” if it could reasonably be expected to reflect (A) Tax liability equal to or in excess of $1 million, (B) a credit or credits equal to or in excess of $1 million or (C) a loss or losses equal to or in excess of $3 million, in each case with respect to the requesting Party.

Section 3.07 Company Carrybacks and Claims for Refund.

Lilly may in good faith advise the Company in writing of the amount, if any, of any Tax Attributes which Lilly determines, in its sole and absolute discretion, shall be allocated or apportioned to the Company Group under applicable Law; provided, that this Section 3.08 shall not be construed as obligating Lilly to undertake any such determination. The Company and all members of the Company Group shall prepare all Tax Returns in accordance with such written notice. The Company agrees that it shall not dispute Lilly’s allocation or apportionment of Tax Attributes. The Company may request that Lilly undertake a determination of the portion, if any, of any particular Tax Attribute to be allocated or apportioned to the Company Group under applicable Law; to the extent that Lilly determines, in its sole and absolute discretion, not to undertake such determination, or does not otherwise advise the Company of its intention to undertake such determination within 20 Business Days of the receipt of such request, the Company shall be permitted to undertake such determination at its own cost and expense and shall notify Lilly of its determination, which determination shall not be binding upon Lilly.

(iii) Notwithstanding anything in Section 6.04(a) or Section 6.04(c)(i) or any other provision of this Agreement or the Separation Agreement to the contrary, with respect to (A) any Tax-Related Loss resulting from Section 355(e) of the Code (other than as a result of an acquisition of a Fifty-Percent or Greater Interest in the Company) and (B) any other Tax-Related Loss resulting (for the absence of doubt, in whole or in part) from an acquisition after the Distribution of any stock or assets of Lilly (or any Lilly Affiliate) by any means whatsoever by any Person, Lilly shall be responsible for, and shall indemnify and hold harmless the Company and its Affiliates and each of their respective officers, directors and employees from and against, one hundred percent (100%) of such Tax-Related Loss.

(d) The Company shall pay Lilly the amount of any Tax-Related Losses for which the Company is responsible under this Section 6.04: (A) in the case of Tax-Related Losses described in clause (i) of the definition of Tax-Related Losses no later than two Business Days prior to the date Lilly files, or causes to be filed, the applicable Tax Return for the year of the Contribution or Distribution, as applicable (the “Filing Date”) (provided, that if such Tax-Related Losses arise pursuant to a Final Determination described in clause (i), (ii) or (iii) of the definition of Final Determination, then the Company shall pay Lilly no later than two Business Days after the date of such Final Determination with interest calculated at the Prime Rate plus two percent, compounded semiannually, from the date that is two Business Days prior to the Filing Date through the date of such Final Determination) and (B) in the case of Tax-Related Losses described in clause (ii) or (iii) of the definition of Tax-Related Losses, no later than two Business Days after the date Lilly pays such Tax-Related Losses. Lilly shall pay the Company the amount of any Tax-Related Losses (described in clause (ii) or (iii) of the definition of Tax-Related Loss) for which Lilly is responsible under this Section 6.04 no later than two Business Days after the date the Company pays such Tax-Related Losses.

Section 7. Assistance and Cooperation.

Section 7.01 Assistance and Cooperation.

(a) The Parties shall cooperate (and cause their respective Affiliates to cooperate) with each other and with each other’s agents, including accounting firms and legal counsel, in connection with Tax matters relating to the Parties and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed. Such cooperation shall include making all information and documents in their possession relating to the other Party and its Affiliates available to such other Party as provided in Section 8. Each of the Parties shall also make available to the other, as reasonably requested and available, personnel (including officers, directors, employees and agents of the Parties or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. The Parties shall cooperate pursuant to this Section 7 to seek any competent authority relief that may be available with respect to any Tax detriment that would be suffered by a member of the Lilly Group, on the one hand, or a member of the Company Group, on the other hand, absent such competent authority relief. The Company shall cooperate with Lilly and take any and all actions reasonably requested by Lilly in connection with obtaining the Tax Opinions (including, without limitation, by making any new representation or covenant, confirming any previously made representation or covenant or providing any materials or information requested by any Tax Advisor or Tax Authority; provided, that the Company shall not be required to make or confirm any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control).

(b) Any information or documents provided under this Section 7 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 administrative or judicial proceedings relating to Taxes. Notwithstanding any other provision of this Agreement or any other agreement, (i) neither Lilly nor any Lilly Affiliate shall be required to provide the Company or any Affiliate of the Company or any other Person access to or copies of any information, documents or procedures (including the proceedings of any Tax Contest) other than information, documents or procedures that relate to the Company, the business or assets of the Company or any Affiliate of the Company and (ii) in no event shall Lilly or any Lilly Affiliate be required to provide the Company, any Affiliate of the Company or any other Person access to or copies of any information or documents if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that Lilly determines that the provision of any information or documents to the Company or any Affiliate of the Company could be commercially detrimental, violate any Law or agreement or waive any Privilege, the Parties shall use reasonable best efforts to permit compliance with its obligations under this Section 7 in a manner that avoids any such harm or consequence.

Section 7.02 Income Tax Return Information. The Company and Lilly acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by Lilly or the Company pursuant to Section 7.01 or this Section 7.02. The Company and Lilly acknowledge that failure to conform to the reasonable deadlines set by Lilly or the Company could cause irreparable harm. Each Party shall provide to the other Party information and documents relating to its Group required by the other Party to prepare Tax Returns, including, but not limited to, any pro forma returns required by the Responsible Party for purposes of preparing such Tax Returns. Any information or documents the Responsible Party requires to prepare such Tax Returns shall be provided in such form as the Responsible Party reasonably requests and at or prior to the time reasonably specified by the Responsible Party so as to enable the Responsible Party to file such Tax Returns on a timely basis.

Section 7.03 Reliance by Lilly. If any member of the Company Group supplies information to a member of the Lilly Group in connection with a Tax liability and an officer of a member of the Lilly Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Lilly Group identifying the information being so relied upon, the chief financial officer of the Company (or any officer of the Company as designated by the chief financial officer of the Company) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete.

Section 7.04 Reliance by the Company. If any member of the Lilly Group supplies information to a member of the Company Group in connection with a Tax liability and an officer of a member of the Company Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Company Group identifying the information being so relied upon, the chief financial officer of Lilly (or any officer of Lilly as designated by the chief financial officer of Lilly) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete.

Section 8. Tax Records.

Section 8.01 Retention of Tax Records. Each Party shall preserve and keep all Tax Records exclusively relating to the assets and activities of its Group for Pre-Deconsolidation Periods, and Lilly shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Deconsolidation Tax Periods, for so long as the contents thereof may become material in the administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (i) the expiration of any applicable statutes of limitations, or (ii) seven years after the Deconsolidation Date (such later date, the “Retention Date”). After the Retention Date, each Party may dispose of such Tax Records upon 60 Business Days’ prior written notice to the other Party. If, prior to the Retention Date, a Party reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 8 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Party agrees, then such first Party may dispose of such Tax Records upon 60 Business Days’ prior notice to the other Party. Any notice of an intent to dispose given pursuant to this Section 8.01 shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Party shall have

the opportunity, at its cost and expense, to copy or remove, within such 60 Business Day period, all or any part of such Tax Records.

Section 8.02 Access to Tax Records. The Parties and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or stored on any computer program or information technology system) in their possession and shall permit the other Party and its Affiliates, authorized agents and representatives and any representative of a Taxing Authority or other Tax auditor direct access, at the cost and expense of such other Party, during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the other Party in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement.

Section 8.03 Preservation of Privilege. No member of the Company Group shall provide access to, copies of, or otherwise disclose to any Person any documentation relating to Taxes existing prior to the final Distribution Date to which Privilege may reasonably be asserted without the prior written consent of Lilly, such consent not to be unreasonably withheld.

Section 9. Tax Contests.

Section 9.01 Notice. Each of the Parties shall provide prompt notice to the other Party of any written communication from a Tax Authority regarding any pending Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware related to Taxes for Tax Periods for which it is indemnified by the other Party hereunder or for which it may be required to indemnify the other Party hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Tax 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 notice and other documents received from any Tax Authority in respect of any such matters. If an indemnified Party has knowledge of an asserted Tax liability with respect to a matter for which it is to be indemnified hereunder and such Party fails to give the indemnifying Party prompt notice of such asserted Tax liability and the indemnifying Party is entitled under this Agreement to contest the asserted Tax liability, then (i) if the indemnifying Party is precluded from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying Party shall have no obligation to indemnify the indemnified Party for any Taxes arising out of such asserted Tax liability, and (ii) if the indemnifying Party is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying Party, then any amount which the indemnifying Party is otherwise required to pay the indemnified Party pursuant to this Agreement shall be reduced by the amount of such detriment.

Section 9.02 Control of Tax Contests.

(a) Separate Returns. In the case of any Tax Contest with respect to any Separate Return, the Party having liability for the Tax pursuant to Section 2 hereof shall have exclusive

control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Section 9.02(c) and Section 9.02(d) below.

(b) Joint Return. In the case of any Tax Contest with respect to any Joint Return, Lilly shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Section 9.02(c) and Section 9.02(d) below.

(c) Settlement Rights. The Controlling Party shall have the sole right to contest, litigate, compromise and settle any Tax Contest without obtaining the prior consent of the Non-Controlling Party. 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 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 copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; (iv) the Controlling Party shall consult with the Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest; and (v) 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 and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, 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. In the case of any Tax Contest described in Section 9.02(a) or Section 9.02(b), “Controlling Party” means the Party entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the other Party.

(d) Tax Contest Participation. Unless waived by the Parties in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement. The failure of the Controlling Party to provide any notice specified in this Section 9.02(d) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, 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.

(e) Power of Attorney. Each member of the Company Group shall execute and deliver to Lilly (or such member of the Lilly Group as Lilly shall designate) any power of attorney or other similar document reasonably requested by Lilly (or such designee) in connection with any Tax Contest (as to which Lilly is the Controlling Party) described in this Section 9. Each member of the Lilly Group shall execute and deliver to the Company (or such member of the Company Group as the Company shall designate) any power of attorney or other similar document requested by the Company (or such designee) in connection with any Tax Contest (as to which the Company is the Controlling Party) described in this Section 9.

Section 10. Effective Date. This Agreement shall be effective as of the date hereof.

Section 11. Treatment of Payments.

Section 11.01 Treatment of Tax Indemnity Payments. In the absence of any change in Tax treatment under the Code or except as otherwise required by other applicable Tax Law, any Tax indemnity payments made by a Party under this Agreement shall be reported for Tax purposes by the payor and the recipient as distributions or capital contributions, as appropriate, occurring immediately before the Deconsolidation (but only to the extent the payment does not relate to a Tax allocated to the payor in accordance with Section 1552 of the Code or the Treasury Regulations thereunder or Treasury Regulations Section 1.1502-33(d) (or under corresponding principles of other applicable Tax Laws)) or as payments of an assumed or retained liability. Except to the extent provided in Section 11.02, any Tax indemnity payment made by a Party under this Agreement shall be increased as necessary so that after making all payments in respect of Taxes imposed on or attributable to such indemnity payment, the recipient Party receives an amount equal to the sum it would have received had no such Taxes been imposed.

Section 11.02 Interest Under This Agreement. Notwithstanding anything herein to the contrary, to the extent one Party (“Indemnitor”) makes a payment of interest to another Party (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by Law) and as interest income by the Indemnitee (includible in income to the extent provided by Law). The amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee.

Section 12. Disagreements.

Section 12.01 Discussion. The Parties mutually desire that friendly collaboration will continue between them. Accordingly, they will use good faith efforts, and they will cause their respective Group members to use good faith efforts, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement (a “Dispute”) between any member of the Lilly Group and any member of the Company Group as to the interpretation of any provision of this Agreement or the

performance of obligations hereunder, the Tax departments of the Parties shall negotiate in good faith to resolve the Dispute.

Section 12.02 Escalation. If such good faith negotiations do not resolve the Dispute, then the matter, upon written request of either Party, will be referred for resolution to representatives of the Parties at a senior level of management of the Parties pursuant to the procedures set forth in Section 8.02(a) of the Separation Agreement.

Section 12.03 Referral to Tax Advisor. If the Parties are not able to resolve the Dispute through the escalation process referred to above, then the matter will be referred to a Tax Advisor acceptable to each of the Parties to act as an arbitrator in order to resolve the Dispute. In the event that the Parties are unable to agree upon a Tax Advisor within 15 Business Days following the completion of the escalation process, the Parties shall each separately retain an independent, nationally recognized law or accounting firm (each, a “Preliminary Tax Advisor”), which Preliminary Tax Advisors shall jointly select a Tax Advisor on behalf of the Parties to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to the Parties of its resolution of any such Dispute as soon as practical, but in any event no later than 30 Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Parties. Following receipt of the Tax Advisor’s written notice to the Parties of its resolution of the Dispute, the Parties shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. Each Party shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor (and the Preliminary Tax Advisors, if any). All fees and expenses of the Tax Advisor (and the Preliminary Tax Advisors, if any) in connection with such referral shall be shared equally by the Parties.

Section 12.04 Injunctive Relief. Nothing in this Section 12 will prevent either Party from seeking injunctive relief if any delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and irreparable injury to either Party. Notwithstanding anything to the contrary in this Agreement, Lilly and the Company are the only members of their respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of Lilly and the Company will cause its respective Group members not to commence any dispute resolution procedure other than through such Party as provided in this Section 12.
