ARTICLE II

GENERAL PRINCIPLES; EMPLOYMENT GENERALLY

2.1 SITC Group Employee Liabilities. Except as specifically provided in this Agreement or the Separation Agreement, the SITC Group will be solely responsible for (a) all employment, compensation and employee benefits Liabilities relating to, arising out of or resulting from the SITC Group’s employment and (if applicable) termination of the SITC Group Employees, Former Employees, and CURB Group Employees, (b) all Liabilities arising under each SITC Benefit Plan, and (c) any other Liabilities expressly assigned or allocated to a SITC Group member under this Agreement.

2.2 CURB Group Employee Liabilities. Except as specifically provided in this Agreement or the Separation Agreement, the CURB Group will be solely responsible for (a) all employment, compensation and employee benefits Liabilities relating to, arising out of or resulting from the CURB Group’s employment and (if applicable) termination of the CURB Group Employees and Subsequent Transferees after the Effective Time, (b) all Liabilities relating to, arising out of or resulting from any CURB Benefit Plan, and (c) any other Liabilities expressly assigned or allocated to a CURB Group member under this Agreement.

2.3 Continuation of Employment. Except as required by applicable Law, SITC and its Affiliates shall take all actions necessary to ensure that, as of immediately prior to the Effective Time, (a) all Employees intended by the Parties to be CURB Group Employees, including any such Employees who are on an approved leave of absence, are employed by a member of the CURB Group and (b) all Employees intended by the Parties to be SITC Group Employees are employed by a member of the SITC Group. Notwithstanding the foregoing or any other provision to the contrary, nothing in this Section 2.3, the Separation Agreement or any Ancillary Agreement shall prevent members of the CURB Group, in their sole discretion, from making offers of employment to any Employee of the SITC Group before or after the Effective Time. For purposes of clarity, an offer of employment with the CURB Group made by a CURB Group member or Employee to an Employee of the SITC Group will not violate any non-solicitation provisions in any Employment Agreement or other contract to which a CURB Group Employee is a party.

2.4 Service Recognition. CURB OP shall give, or shall cause another member of the CURB Group to give, each CURB Group Employee credit for purposes of eligibility and vesting under any CURB Benefit Plan for such CURB Group Employee’s service with the SITC Group or the CURB Group prior to the Effective Time to the same extent such service was recognized by the corresponding SITC Benefit Plan immediately prior to the Effective Time; provided, however, that such service shall not be recognized to the extent that such recognition would result in the duplication of benefits or as otherwise provided by applicable Law.

2.5 No Separation From Service or Termination of Employment. None of the Separation, the Distribution or the assignment, transfer or continuation of employment of any Employee of SITC or any of its Affiliates at or prior to the Effective Time (including in accordance with Section 2.3 hereof) shall be deemed a separation from service or termination of employment entitling such Employee to be eligible to participate in, or to receive payment of, severance or other termination payments or benefits under any applicable Law, SITC Benefit Plan or CURB Benefit Plan.

2.6 Former Employees. No member of the CURB Group shall have any Liabilities with respect to Former Employees, if any, as of (or after) the Effective Time. SITC shall retain all Liabilities, if any, with respect to Former Employees. Notwithstanding the foregoing, if after the Effective Time a member of the CURB Group hires a Former Employee, then CURB and the applicable member of the CURB Group shall be responsible for any Liabilities that relate to, arise out of, or result from the CURB Group member’s employment of such Former Employee.

ARTICLE III

Prior to the Effective Time, the Parties will take all actions necessary to cause the plan sponsor of the SITE Centers Corp. 401(k) Plan & Trust (the “SITC 401(k) Plan”) to change from SITC to a member of the CURB ERISA Group (the transferred plan, the “CURB 401(k) Plan”), and to ensure that the members of the SITC ERISA Group, as applicable, are participating employers in the CURB 401(k) Plan. The terms of participation of the members of the SITC ERISA Group in the CURB 401(k) Plan as participating employers will be governed by the applicable plan document, agreements with applicable third party administrators, the Shared Services Agreement, and any other documents governing the administration and operation of the CURB 401(k) Plan (the “401(k) Plan Governing Documents”).

(b) Obligations and Liabilities.

(i) Through the Effective Time. Except as otherwise provided in this Section 3.1 or the 401(k) Plan Governing Documents, (A) SITC and the SITC ERISA Group shall retain all Liabilities that relate to, arise out of or result from any employer contributions, including matching contributions (including any true-up contributions, if applicable), profit-sharing contributions, and employer non-elective contributions, accrued under the SITC 401(k) Plan or the CURB 401(k) Plan (as applicable) for all participants through the Effective Time, determined in accordance with the terms and provisions of the applicable plan, ERISA and the Code, and based on all service performed and compensation accrued through the Effective Time, and (B) SITC and the SITC ERISA Group will be solely and exclusively responsible for all other obligations and Liabilities arising prior to the Effective Time that relate to, arise out of or result from the SITC 401(k) Plan and CURB 401(k) Plan, as applicable.

(ii) Following the Effective Time. All Liabilities that relate to, arise out of or result from employer contributions, including matching contributions (including any true-up contributions, if applicable), profit-sharing contributions, and employer non-elective contributions, accrued under the CURB 401(k) Plan following the Effective Time, determined in accordance with the terms and provisions of the CURB 401(k) Plan, ERISA and the Code, and based on all service performed and compensation accrued from and after the Effective Time shall be the responsibility of the CURB ERISA Group member or the SITC ERISA Group member that employs the Employee receiving the contribution, as applicable, during the time period to which the contribution relates. All other obligations and Liabilities arising on and after the Effective Time, that relate to, arise out of or result from the CURB 401(k) Plan shall be the responsibility of CURB and the CURB ERISA Group, except that SITC and the SITC ERISA Group will be responsible for all other obligations and Liabilities arising on and after the Effective Time, that relate to, arise out of or result from the SITC ERISA Group’s participation in the CURB 401(k) Plan except as provided in any 401(k) Plan Governing Documents.

ARTICLE IV

HEALTH AND WELFARE PLANS

4.1 CURB Health and Welfare Plans. Members of the CURB ERISA Group will continue to participate in the group health plan and other welfare benefit plans sponsored by the SITC ERISA Group and listed on Schedule 4.1 (the “SITC Welfare Plans”) from the Distribution Date through the termination date of the Shared Services Agreement, or such earlier date as the Parties may reasonably agree (the earlier of such dates, the “Welfare Plan Transfer Date”). At CURB’s election, and to the extent the insurers of the SITC Welfare Plans consent, the Parties will take all actions necessary to cause the plan sponsor of the SITC Welfare Plans to change from SITC to a member of the CURB ERISA Group (the transferred plans, the “CURB Welfare Plans”) effective as of the Welfare Plan Transfer Date. The terms of the CURB ERISA Group’s participation in the SITC Welfare Plans as participating employers and the transfer of the sponsorship of such plans to a member of the CURB ERISA Group will be governed by the applicable plan documents, agreements with applicable third party administrators, the Shared Services Agreement, and any other documents governing the administration and operation of the SITC Welfare Plans and CURB Welfare Plans, as applicable, (the “Welfare Plan Governing Documents”). Except as otherwise provided in this Article IV or the Welfare Plan Governing Documents, SITC and the SITC ERISA Group will be solely and exclusively responsible for (a) all obligations and Liabilities arising prior to the Effective Time that relate to, arise out of or result from the SITC Welfare Plans, including for all welfare benefit claims incurred prior to the Distribution Date and (b) all obligations and liabilities arising on and after the Effective Time that relate to, arise out of or result from the SITC ERISA Group’s participation in the SITC Welfare Plans and CURB Welfare Plans, as applicable, including for all welfare benefit claims

of an Employee or their dependents incurred while an Employee is employed by a SITC ERISA Group member. Except as otherwise provided in this Article IV or the Welfare Plan Governing Documents, CURB and the CURB ERISA Group will be solely and exclusively responsible for all obligations and Liabilities arising on and after the Effective Time, that relate to, arise out of or result from the CURB ERISA Group’s participation in the SITC Welfare Plans and the CURB Welfare Plans, as applicable, including for all welfare benefit claims of an Employee or their dependents incurred while an Employee is employed by a CURB ERISA Group member. For purposes of this Article IV, a claim or Liability is deemed to be incurred: (i) with respect to medical, dental, vision and/or prescription drug benefits, upon the rendering of health services giving rise to such claim or Liability; (ii) with respect to life insurance, accidental death and dismemberment and business travel accident insurance, upon the occurrence of the event giving rise to such claim or Liability; (iii) with respect to disability benefits, upon the date of an Employee’s disability, as determined by the disability benefit insurance carrier or claim administrator, giving rise to such claim or Liability; and (iv) with respect to a period of continuous hospitalization, upon the date of admission to the hospital.

4.2 Separation of Welfare Plans. Notwithstanding the provisions of Section 4.1, if the continued participation of members of the CURB ERISA Group in the SITC Welfare Plans or, following the Welfare Plan Transfer Date, participation by members of the SITC ERISA Group in the CURB Welfare Plans is no longer permitted under applicable law or by the insurers of the SITC Welfare Plans or CURB Welfare Plans, then such continued participation shall cease and CURB and SITC will reasonably cooperate to ensure the employees of the CURB ERISA Group and SITC ERISA Group have continuous coverage under group health and welfare benefit plans.

4.3 COBRA and HIPAA Compliance. The plan sponsor of the SITC Welfare Plans and the CURB Welfare Plans, as applicable, will be responsible for compliance with the requirements of COBRA and the certificate of creditable coverage requirements of HIPAA with respect to any Employees or any of their covered dependents who participate in the applicable plan at the time they incur a qualifying event or loss of coverage.

4.4 Workers Compensation. The ownership and administration of workers compensation insurance shall be governed by Section 5.1 of the Separation Agreement regarding insurance matters. For the avoidance of doubt, nothing in this Agreement shall be interpreted to allocate between the Parties the claims and Liabilities under any workers compensation insurance policies.

ARTICLE V

EQUITY PLANS AND AWARDS

5.1 Adjustment of Outstanding Awards. Each SITC Compensation Award that is outstanding as of the Distribution will be adjusted as described in this Section 5.1; provided, however, that, effective immediately prior to the Distribution, the SITC Compensation Committee may provide for different adjustments with respect to some or all of a holder’s SITC Compensation Awards. For greater certainty, any adjustments made by the SITC Compensation Committee will be deemed incorporated by reference herein as if fully set forth below and will be binding on the Parties hereto and their respective Subsidiaries.

(a) Options. Each SITC Option generally will be adjusted in the manner described in this Section 5.1(a), effective as of the Distribution Date and immediately prior to the Distribution, so that immediately following the Distribution each SITC Option holder will hold an Adjusted SITC Option in lieu of the SITC Options previously held. The following procedure will generally be applied to each SITC Option with the same grant date and exercise price held by each SITC Option holder as of the Distribution Date:

(i) Each Adjusted SITC Option will have an exercise price equal to the product (rounded up to the nearest cent) of (A) the applicable Option Exercise Price multiplied by (B) a fraction, (1) the numerator of which is the Post-Distribution SITC Share Price and (2) the denominator of which is the Pre-Distribution SITC Share Price (such product, the “SITC Exercise Price”).

(ii) The number of SITC Shares subject to the Adjusted SITC Options will be equal to the product (which will be rounded down to the nearest whole share) of (X) the number of shares subject to the SITC Option held by such SITC Option holder immediately prior to the Distribution Date and (Y) a fraction, the numerator which is the Pre-Distribution SITC Share Price and the denominator of which is the Post-Distribution SITC Share Price.

(iii) Such Adjusted SITC Options will be subject to the same vesting requirements and dates and other terms and conditions as the SITC Options to which they relate.

(b) RSUs. With respect to SITC RSUs:

(i) Held by SITC Participants. SITC RSUs held by each SITC Participant will generally be adjusted, effective as of the Distribution Date and immediately prior to the Distribution, pursuant to the adjustments provisions of the SITC Equity Plan, and will be subject to substantially the same terms, vesting conditions and other restrictions, if any, that were applicable to such SITC RSUs immediately prior to the Distribution Date. The number of such Adjusted SITC RSUs for each such SITC Participant will be equal to the product (which will be rounded down to the nearest whole share) of (A) the number of SITC RSUs outstanding immediately prior to the Distribution Date and (B) a fraction, (1) the numerator of which is the Pre-Distribution SITC Share Price and (2) the denominator of which is the Post-Distribution SITC Share Price.

(ii) Held by CURB Participants. SITC RSUs held by each CURB Participant will, effective as of the Distribution Date and immediately prior to the Distribution, generally be adjusted by converting them into an award of Adjusted CURB RSUs. Pursuant to the adjustments provisions of the SITC Equity Plan, the award of Adjusted CURB RSUs will be subject to substantially the same terms, vesting conditions and other restrictions, if any, that were applicable to such SITC RSUs immediately prior to the Distribution Date. The number of such Adjusted CURB RSUs for each such CURB Participant will be equal the product (which will be rounded down to the nearest whole share) of (1) the number of SITC RSUs held by such CURB Participant immediately prior to the Distribution Date and (2) a fraction, (a) the numerator of which is the Pre-Distribution SITC Share Price and (b) the denominator of which is the CURB Per-Share Value.

(i) Determination of Earned Award. SITC PRSU awards outstanding immediately prior to the Distribution that are held by a SITC Participant or by a CURB Participant will be determined to have been earned as of the Distribution Date in an amount equal to the greater of (A) the number of SITC PRSUs that are earned based upon the achievement of the management objectives applicable to such SITC PRSUs measured as of the close of trading on the trading day immediately prior to the Distribution Date, and (B) 150% of the number of SITC PRSUs that would have been earned at target achievement for the performance period applicable to such SITC PRSUs. Such determination will be made by the SITC Compensation Committee in accordance with the applicable SITC Equity Plan. Any portion of a SITC PRSU award that is not earned as of the Distribution Date will be cancelled and forfeited. Such earned portion of the SITC PRSU awards will be adjusted for SITC Participants and CURB Participants as set forth in Sections 5.1(c)(ii) and (iii).

(ii) Earned Awards Held by SITC Participants. The earned portion of any SITC PRSU award held by each SITC Participant will generally be converted, effective as of the Distribution Date and immediately prior to the Distribution, pursuant to the adjustments provisions of the SITC Equity Plan, into a Replacement SITC RSU award, which will be subject to substantially the same terms as the related SITC PRSUs (including vesting based on continued employment with SITC) except that the Replacement SITC RSU award will not be subject to any additional performance objectives and related dividend equivalents credited with respect to such Replacement SITC RSUs after the Distribution Date will be paid in cash on a current basis. The number of such Replacement SITC RSUs for each such SITC Participant will be equal to the product (which will be rounded down to the nearest whole share) of (A) the number of SITC PRSUs earned by such SITC Participant as determined under Section 5.1(c)(i) and (B) a fraction, (1) the numerator of which is the Pre-Distribution SITC Share Price and (2) the denominator of which is the Post-Distribution SITC Share Price.

(iii) Earned Awards Held by CURB Participants. The earned portion of any SITC PRSU award held by each CURB Participant will generally be converted, effective as of the Distribution Date and immediately prior to the Distribution, pursuant to the adjustments provisions of the SITC Equity Plan, into a Replacement CURB RSU award, which will be subject to substantially the same terms as the related SITC PRSUs (including vesting based on continued employment with SITC), except that the Replacement CURB RSU award will not be subject to any additional performance objectives and related dividend equivalents credited with respect to such Replacement CURB RSUs after the Distribution Date will be paid in cash on a current basis. The number of such Replacement CURB RSUs for each such CURB Participant will be equal the product (which will be rounded down to the nearest whole share) of (A) the number of SITC PRSUs earned by such CURB Participant as determined under Section 5.1(c)(i) and (B) a fraction, (1) the numerator of which is the Pre-Distribution SITC Share Price and (2) the denominator of which is the CURB Per-Share Value.

(d) Subsequent Transferees. Nothing in this Agreement will require further adjustment or modification of the Adjusted SITC Options, Adjusted SITC RSUs or Replacement SITC RSUs held by SITC Participants who later become Subsequent Transferees in connection with such Subsequent Transferee’s Subsequent Transfer Date, provided that a Subsequent Transferee’s employment with the CURB Group will count as continued employment with the SITC Group for purposes of the service based vesting requirements of the Adjusted SITC RSUs and Replacement RSUs and for purposes of the exercise period for the Adjusted SITC Options.

5.2 Change in Control. If an Adjusted SITC Compensation Award or CURB Compensation Award is subject to accelerated vesting in connection with a change in control, a change in control will be deemed to have occurred (i) with respect to an Adjusted SITC Compensation Award, only upon a change in control of SITC (as defined in the applicable equity incentive plan or award agreement) or (ii) with respect to a CURB Compensation Award, only upon a change in control of CURB (as defined in the applicable equity incentive plan or award agreement). For purposes of Code Section 409A, with respect to the CURB Compensation Awards, if a change in control of SITC occurs prior to a change in control of CURB, the CURB Compensation Awards will not vest by reason of such SITC change in control because the continuation of the CURB Compensation Awards following such SITC change in control will be considered a “replacement award” under the terms of the CURB Compensation Awards. This Section 5.2 will apply to the extent that it does not cause adverse tax consequences under Code Section 409A.

5.3 Establishment of CURB Equity Plan. Prior to the Distribution Date, CURB will, or will cause another member of the CURB Group to, establish equity compensation plans, so that upon the Distribution, CURB or another member of the CURB Group will have in effect an equity compensation plan that allows grants of equity compensation awards subject to substantially the same terms as those that apply to the corresponding SITC Compensation Awards. From and after the Distribution Date, each CURB Compensation Award will be subject to the terms of the applicable CURB equity compensation plan, the award agreement governing such CURB Compensation Award and any employment agreement to which the applicable holder is a party. From and after the Distribution Date, CURB will retain, pay, perform, fulfill and discharge all Liabilities relating to, arising out of or resulting from the CURB Compensation Awards. SITC will retain, pay, perform, fulfill and discharge all Liabilities relating to, arising out of or resulting from the Adjusted SITC Compensation Awards.

5.4 Section 409A. In all events, the adjustments provided for in this Section 5 will be made in a manner that, as determined by SITC, avoids adverse tax consequences to holders under Code Section 409A.

ARTICLE VI

NONQUALIFIED PLANS

6.1 Establishment of CURB NQDC Plan. Prior to the Effective Time, CURB OP will, or will cause another member of the CURB Group to, establish a nonqualified elective deferred compensation plan and a related rabbi trust (such plan and trust, the “CURB NQDC Plan”). The CURB NQDC Plan will have terms and features that are substantially similar to the SITE Centers Corp. Elective Deferred Compensation Plan (the “SITC Elective Cash Plan”), such that (for the avoidance of doubt), the SITC Elective Cash Plan is substantially replicated by the CURB NQDC Plan. CURB or a member of the CURB Group will be solely responsible for taking all necessary, reasonable, and appropriate actions to establish, maintain, and administer

the CURB NQDC Plan so that it does not result in adverse tax consequences under Code Section 409A. Effective on a date designated by SITC which is prior to the Effective Time (the “NQDC Transfer Date”), the CURB NQDC Plan will assume all Liabilities relating to, arising out of or resulting from benefits earned or accrued (whether or not vested) by CURB Group Employees under the SITC Elective Cash Plan as of the NQDC Transfer Date (the “Assumed NQDC Plan Liabilities”). Within 30 days following the NQDC Transfer Date, SITC will cause the rabbi trust established for the SITE Elective Cash Plan to transfer a cash amount to the rabbi trust established for the CURB NQDC Plan equal to the product of (a) total amount held by the rabbi trust for the SITC Elective Cash Plan as of the NQDC Transfer Date, multiplied by (b) a fraction, the numerator of which is the amount of the Assumed NQDC Plan Liabilities, and the denominator of which is the total amount of the Liabilities for all benefits earned or accrued (whether or not vested) under the SITC Elective Cash Plan as of immediately prior to the NQDC Transfer Date. On or prior to the NQDC Transfer Date, on a date designated by SITC, the CURB Group Employees who are participants in the SITC Elective Cash Plan will cease to be participants in the SITC Elective Cash Plan and will become participants in the CURB NQDC Plan. From and after the NQDC Transfer Date, CURB and the CURB Group will be solely and exclusively responsible for all Liabilities with respect to, or in any way related to, the CURB NQDC Plan, whether accrued before, on or after the Effective Date.

6.2 SITC Nonqualified Plans. From and after the Effective Time, SITC and the SITC Group will be solely and exclusively responsible for all Liabilities relating to, arising out of or resulting from the nonqualified deferred compensation plans sponsored or maintained by a member of the SITC Group (including, but not limited to, the SITC Elective Cash Plan and the SITE Centers Corp. 2005 Directors’ Deferred Compensation Plan) to the extent such Liabilities are not specifically assumed by a CURB Group member or the CURB NQDC Plan pursuant to Section 6.1.

6.3 No Distributions on Separation. The Parties acknowledge that neither the Distribution nor any of the other transactions contemplated by this Agreement, the Separation Agreement or the other Ancillary Agreements will trigger a payment or distribution of compensation under the SITC Elective Cash Plan or any other nonqualified deferred compensation plans sponsored by SITC or members of the SITC Group or the CURB NQDC Plan for any Employee of the SITC Group or CURB Group or Former Employee and, consequently, that the payment or distribution of any compensation to which any Employee of the SITC Group or CURB Group or Former Employee is entitled under any such plan will occur upon such individual’s separation from service (within the meaning of Section 409A of the Code) from the SITC Group or the CURB Group, as applicable, or at such other time as specified in the applicable plan.

6.4 Section 409A. The Parties will cooperate in good faith so that the Distribution will not result in adverse tax consequences under Code Section 409A with respect to any Employee or Former Employee or their respective plan payees, in respect of his or her benefits under the applicable plan.

ARTICLE VII

ADDITIONAL COMPENSATION MATTERS; SEVERANCE

7.1 Annual Bonuses.

(a) 2024 Bonuses for CURB Group Employees. Eligible CURB Group Employees will continue to participate in SITC’s annual bonus plans and policies (the “SITC Annual Incentive Program”), subject to its terms and conditions, up to the date immediately prior to the Distribution Date. On the Distribution Date, such CURB Group Employees shall cease participating in the SITC Annual Incentive Program. For each such CURB Group Employee, SITC will, prior to the Distribution Date, calculate the bonus earned under the SITC Annual Incentive Program for the 2024 performance year based on the achievement of the applicable performance objectives measured as of a date prior to the Distribution Date and prorated based on the number of months in the performance year that occurred prior to the Distribution Date. SITC will remain responsible for and will pay any awards earned by the CURB Group Employees under the SITC Annual Incentive Program up to the Distribution Date on a date prior to the Distribution Date. CURB OP will be responsible for establishing an annual bonus program for the CURB Group Employees for the period beginning on the Distribution Date and ending on December 31, 2024.

(b) Bonuses for SITC Group Employees. Subject to Section 7.1(c), eligible Employees of the SITC Group will continue to participate in the SITC Annual Incentive Program through and after the Distribution Date in accordance with the terms and conditions of the SITC Annual Incentive Program. SITC will be responsible for and will pay any awards earned by eligible Employees of the SITC Group according to the terms of the SITC Annual Incentive Program.

(c) Bonuses for Subsequent Transferees. All Subsequent Transferees will continue to participate in the SITC Annual Incentive Program, subject to its terms and conditions, up to the applicable Subsequent Transfer Date. On such Subsequent Transfer Date, such Subsequent Transferee shall cease participating in the SITC Annual Incentive Program. For each Subsequent Transferee who was eligible to participate in the SITC Annual Incentive Program immediately prior to the Subsequent Transfer Date, the bonus earned under the SITC Annual Incentive Program for the performance year in which the Subsequent Transfer Date occurs will be equal to the bonus earned for the immediately preceding completed performance year, prorated based on the number of days of service with SITC in the performance year in which the Subsequent Transfer Date occurs. SITC will remain responsible for and will pay any awards earned by such Subsequent Transferees under the SITC Annual Incentive Program through the Subsequent Transfer Date prior to the Subsequent Transfer Date.

7.2 Commissions. SITC will remain solely responsible for all Liabilities relating to, arising out of or resulting from the SITE Centers Leasing Commission Program for regional Vice Presidents and leasing staff members (the “SITC Commission Program”) for Employee commissions on all leases signed prior to the Effective Time and, in the case of a Subsequent Transferee, leases signed by members of the SITC Group between the Effective Time and the Subsequent Transfer Date. SITC will continue to be responsible for and will pay such commissions to eligible Employees in accordance with the terms of the SITC Commission

Program, except that: (a) in the case of a CURB Group Employee, continued employment with the SITC Group on and after the Distribution Date will not be required and such commissions will be fully paid by SITC to such CURB Group Employee prior to the Distribution Date, and (b) in the case of a Subsequent Transferee, continued employment with the SITC Group on and after the Subsequent Transfer Date will not be required and such commissions will be fully paid by SITC to such Subsequent Transferee prior to such Subsequent Transferee’s Subsequent Transfer Date. CURB Group Employees will cease participating in the SITC Commission Program effective as of the Distribution Date, and Subsequent Transferees will cease participating in the SITC Commission Program effective as of their Subsequent Transfer Date. For purposes of clarity, SITC shall have no obligation to provide CURB Group Employees with commissions on any leases signed by the CURB Group after the Effective Time.

7.3 Employment Agreements. At and after the Effective Time, a member of the CURB Group will be solely responsible and liable for all Employment Agreements listed on Schedule 7.3 hereto (each, a “CURB Employment Agreement”), and the SITC Group will have no obligations or Liabilities with respect to any CURB Employment Agreement. The SITC Group will retain and be solely responsible for all obligations and Liabilities with respect to, or in any way related to, any Employment Agreement that is not a CURB Employment Agreement.

ARTICLE VIII

GENERAL AND ADMINISTRATIVE

8.1 Non-Termination of Employment; No Third-Party Beneficiaries. Except as expressly provided for in this Agreement or the Separation Agreement, no provision of this Agreement, the Separation Agreement, or any of the other Ancillary Agreements shall be construed to create any right, or accelerate entitlement, to any compensation or benefit whatsoever on the part of any SITC Group Employee, CURB Group Employee or any Former Employee, or future Employee of SITC or any of its Affiliates or of CURB or any of its Affiliates under any SITC Benefit Plan or CURB Benefit Plan or otherwise, nor shall any such provision be construed as an amendment to any employee benefit plan or other employee compensatory or benefit arrangement. Furthermore, nothing in this Agreement is intended to confer upon any Employee or Former Employee any right to continued employment, any recall or similar rights to an Employee on layoff or any type of approved leave, or to change the employment status of any Employee from “at will.”

8.2 Beneficiary Designation/Release of Information/Right to Reimbursement. To the extent permitted by applicable Law and except as otherwise provided for in this Agreement, all beneficiary designations, authorizations for the release of Information and rights to reimbursement made by or relating to CURB Group Employees under SITC Benefit Plans shall be transferred to and be in full force and effect under the corresponding CURB Benefit Plans until such beneficiary designations, authorizations or rights are replaced or revoked by, or no longer apply, to the relevant CURB Group Employee or a beneficiary, dependent or alternate payee of such person.

8.3 Not a Change in Control. The Parties acknowledge and agree that the transactions contemplated by the Separation Agreement, this Agreement or any other Ancillary Agreement do not constitute a “change in control” for purposes of any SITC Benefit Plan or CURB Benefit Plan.

8.4 Code Section 409A. Notwithstanding anything to the contrary herein, if any of the provisions of this Agreement would result in imposition of taxes and/or penalties under Section 409A of the Code, SITC, CURB and CURB OP shall cooperate in good faith to modify the applicable provision so that such taxes and/or penalties do not apply in order to comply with the provisions of Section 409A of the Code.

9.6 No Waiver. Neither the failure nor any delay on the part of a Party to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No waiver shall be effective unless it is in writing and is signed by the Party asserted to have granted such waiver.
