a written request from Parent to assume control over the enforcement of such violation of such Licensed SpinCo IP inside the Parent Field, then Parent shall have, with the prior consent of SpinCo, which will not be unreasonably withheld, the right, but not the obligation, to bring and to control such IP Action (provided that if Parent does not do so within thirty (30) days after the end of such original ninety (90) day-deadline, the right to initiate and control an IP Action shall revert back to SpinCo and shall again be subject to the terms set forth above). For avoidance of doubt, Parent shall not have any right to initiate any IP Action with respect to infringement, misappropriation or other violation of any Licensed SpinCo IP by a Third Party except within the Parent Field. (b) Enforcement Action Process. (i) The Party initiating or otherwise controlling any enforcement IP Action hereunder (the "Enforcing Party"), including the right to communicate any objection or other form of challenge to any Third Party, shall, as between the Parties, have the right to select counsel for any IP Action initiated by it or its designee pursuant to this Section 3.6. The Party that is not the Enforcing Party (the "Non-Enforcing Party") shall, to the extent it is a necessary party to the IP Action (or is otherwise reasonably requested by the enforcing Party), join the Enforcing Party (and/or, if applicable, its designee(s)) at the Enforcing Party's expense and agree to be represented by counsel for the Enforcing Party in any infringement or other IP Action commenced by the Enforcing Party (or its designee) and shall, upon request of the Enforcing Party, execute such documents and perform such other acts as may be reasonably required and requested by the Enforcing Party at the Enforcing Party's expense in connection with such enforcement IP Action; provided, that the Non-Enforcing Party shall have the right to engage, at its cost and expense, independent counsel of its choice to advise such Non-Enforcing Party in connection with such assistance to the Enforcing Party. (ii) The Non-Enforcing Party shall cooperate with, and provide reasonable assistance to, the Enforcing Party (and its designees) in connection with any IP Action brought by the Enforcing Party (or its designee) hereunder to the extent relating to the Licensed SpinCo IP, as may be reasonably requested by the Enforcing Party, including by providing access to relevant documents and other evidence (provided that the Parties shall enter into a joint defense agreement with respect to the common interest privilege protecting such communications in a form reasonably acceptable to the Parties) and making its employees available, subject to the other Party's reimbursement of any costs and expenses incurred by the Non-Enforcing Party in providing such assistance. The Enforcing Party shall keep the Non-Enforcing Party reasonably informed of any determinations or significant developments in any IP Action initiated by it pursuant to this Section 3.6 and, if the Non-Enforcing Party is SpinCo, then the Parent shall reasonably consult with the SpinCo and take into consideration input provided to Parent by SpinCo to the extent reasonable and provided in a timely manner. (c) Allocation of Costs and Recoveries. Unless otherwise mutually agreed by the Parties, (i) the costs and expenses relating to any enforcement IP Action commenced pursuant to this Section 3.6 shall be borne by the Enforcing Party; and (ii) any settlement payments or -11- damages or other monetary awards ("Recoveries") recovered in any IP Action by the Enforcing Party, itself or through its designee, pursuant to this Section 3.6, whether by judgment or settlement, shall be allocated in the following order: (A) to reimburse the Enforcing Party for any costs and expenses incurred by or on behalf of the Enforcing Party and/or its designee(s) with respect to such IP Action, (B) to reimburse the Non-Enforcing Party for any costs and expenses incurred by such Party with respect to such IP Action to the extent the Non-Enforcing Party participated in an IP Action pursuant to this Section 3.6 (and has not already been reimbursed by the Enforcing Party), including if it joins such IP Action (but excluding, for the avoidance of doubt, the cost of any counsel employed by the Non-Enforcing Party), and (C) the remainder shall be allocated to the Enforcing Party. (d) Settlement of Enforcement IP Action. The Enforcing Party shall not settle, or enter into a voluntary consent judgment with respect to, any enforcement IP Action under this Section 3.6 in a manner that would
