GENERAL PRINCIPLES

Section 2.01Allocation of Liabilities.

(a)Aptevo Liabilities. Effective as of the Distribution Date, and except as expressly provided in this Agreement, Aptevo hereby assumes (or retains) and agrees to pay, perform, fulfill, and discharge all Liabilities to the extent relating to, arising out of, or resulting from:

(i)the employment (or termination of employment) of each Transferred Employee on or after the Distribution Date (including, in each case, all Liabilities relating to, arising out of, or resulting from Employment Taxes, any Emergent Benefit Plan or any Aptevo Benefit Plan);

(ii)the employment of each Aptevo Employee prior to the Distribution Date (including all Liabilities relating to, arising out of, or resulting from Employment Taxes, any Emergent Benefit Plan or any Aptevo Benefit Plan) to the extent such Liabilities have not been paid, performed, fulfilled or discharged by Emergent prior to the Distribution Date; and

(iii)obligations, Liabilities, and responsibilities expressly assumed or retained by Aptevo pursuant to this Agreement.

(b)Emergent Liabilities.  Effective as of the Distribution Date, and except as expressly provided in this Agreement, Emergent hereby retains (or assumes) and agrees to pay,

5

perform, fulfill, and discharge all Liabilities to the extent relating to, arising out of, or resulting from: 

(i)the employment (or termination of employment) of each Emergent Employee prior to, on, or after the Distribution Date (including all Liabilities to the extent relating to, arising out of, or resulting from Employment Taxes or any Emergent Benefit Plan); and

(ii)obligations, Liabilities, and responsibilities expressly retained or assumed by Emergent pursuant to this Agreement.

(c)Other Liabilities.  To the extent that this Agreement does not cover particular obligations, Liabilities or responsibilities that relate to, arise out of, or result from employment (or termination of employment), Employment Taxes or any Benefit Plan and the Parties later determine that they should be allocated in connection with the Separation, such obligations, Liabilities or responsibilities shall be handled in a manner similar to the manner in which this Agreement handles comparable obligations, Liabilities or responsibilities, subject to the mutual agreement of the Parties.

Section 2.02Employment with Aptevo.

(a)Employment Transfers.  The Parties intend for Aptevo Employees to transfer to the Aptevo Group and shall use commercially reasonable efforts and cooperate with each other to effectuate this intent.  Except as otherwise mutually agreed upon by the Parties, as of the Distribution Date, the Aptevo Group shall continue to employ (on a basis consistent with Section 2.02(b)) each Aptevo Employee.  Each Aptevo Employee who continues employment with the Aptevo Group following the Distribution Date will be referred to in this Agreement as a “Transferred Employee.”

(b)Compensation and Benefits.

(i)Emergent shall use commercially reasonable efforts to provide that, except as otherwise mutually agreed upon by the Parties, no transfer of employment of an Aptevo Employee prior to the Distribution Date to an entity that will be a part of the Aptevo Group will cause such Aptevo Employee to lose coverage under any Emergent Benefit Plan prior to the Distribution Date.  Except as expressly provided in this Agreement or as required by Law, no Transferred Employee shall participate in any Emergent Benefit Plan following the Distribution Date.

(ii)Except as expressly provided in this Agreement, the Aptevo Group shall provide to each Transferred Employee as of the Distribution Date (A) base salary at at least the same rate as provided to that Transferred Employee immediately prior to the Distribution Date and (B) cash incentive compensation opportunities that are comparable in the aggregate to those cash incentive compensation opportunities offered under the corresponding Emergent Benefit Plan(s) immediately prior to the Distribution Date.

(iii)Except as expressly provided in this Agreement, the Aptevo Group shall take commercially reasonable efforts to provide the Transferred Employees with total cash

6

and non-cash compensation that is substantially comparable in the aggregate to cash and non-cash compensation provided by the Emergent Group immediately prior to the Distribution Date.   

Nothing in (ii) or (iii) of this section 2.02(b) shall prevent the Aptevo Group from modifying the compensation and benefits of a Transferred Employee after the Distribution Date.

(c)Service Credit.  Except as expressly provided in this Agreement or to the extent it would result in a duplication of benefits, Aptevo and each Aptevo Benefit Plan shall give each Transferred Employee credit for all service with the Emergent Group and shall calculate such service as it would be calculated by Emergent or under the corresponding Emergent Benefit Plan as of the Distribution Date.

Section 2.03Establishment of Aptevo Plans.

(a)Generally.  Prior to the Distribution Date, except to the extent they would result in the imposition of a commercially unreasonable cost or administrative burden on Aptevo, Aptevo shall take commercially reasonable efforts to adopt Benefit Plans (and related trusts, if applicable, as determined by the Parties), and Aptevo shall take commercially reasonable efforts to provide that such Aptevo Benefit Plans have terms that are substantially similar to those of the corresponding Emergent Benefit Plans.  For the avoidance of doubt, Aptevo may limit participation in any Aptevo Benefit Plan to Transferred Employees who participated in the corresponding Emergent Benefit Plan immediately prior to the Distribution Date.

(b)Plan Information and Operation.  Aptevo shall require Transferred Employees to submit new elections with respect to the Aptevo Benefit Plans.  Except as provided in this Agreement, the Distribution and the transfer of any Employee’s employment to the Aptevo Group shall not cause a distribution from or payment of benefits under any Emergent Benefit Plan.  

ARTICLE III
U.S.  QUALIFIED RETIREMENT PLAN

Section 3.01401(k) Plan.

(a)Establishment of Aptevo 401(k) Plan.  Prior to the Distribution Date, Aptevo shall take any and all steps necessary or appropriate to establish a defined contribution plan and trust to be effective as of the Distribution Date for the benefit of Transferred Employees (the “Aptevo 401(k) Plan”).  The Aptevo Group shall be responsible for taking or causing to be taken all necessary, reasonable and appropriate action to establish, maintain, and administer the Aptevo 401(k) Plan so that it qualifies under Section 401(a) of the Code and the related trust thereunder is exempted from federal income taxation under Section 501(a)(1) of the Code.  For the avoidance of doubt, nothing in this Section 3.01 shall be construed to require Aptevo to maintain any investment option which the fiduciaries (as such term is defined in Section 3(21) of ERISA) of the Aptevo 401(k) Plan deem to be imprudent or inappropriate for the Aptevo 401(k) Plan or which cannot be maintained without commercially unreasonable cost or administrative burden for the Aptevo 401(k) Plan and its administrator.  

7

(b)Assumption of Liabilities and Transfer of Assets.  

(i)Effective as of the Distribution Date or at such other time as is mutually agreed to by the Parties, but subject to the asset transfer specified in Section 3.01(b)(ii) below, the Aptevo 401(k) Plan shall assume and be solely responsible for all Liabilities for or relating to Transferred Employees under the Emergent 401(k) Plan. The Aptevo Group shall be responsible for all ongoing rights of or relating to Aptevo Employees for future participation (including the right to make contributions through payroll deductions) in the Aptevo 401(k) Plan.

(ii)Effective as of the Distribution Date or at such other time as is mutually agreed to by the Parties, Emergent shall cause the account balances (including any outstanding loan balances) in the Emergent 401(k) Plan attributable to Transferred Employees to be transferred in cash and in-kind (including, but not limited to, participant loans), to the Aptevo 401(k) Plan, and Aptevo shall cause the Aptevo 401(k) Plan to accept such transfer or accounts and underlying assets and, effective as of the date of such transfer, to assume and to fully perform pay or discharge, all obligations of the Emergent 401(k) Plans relating to the accounts of Transferred Employees (to the extent those assets related to those accounts are actually transferred from the Emergent 401(k) Plan). The transfer shall be conducted in accordance with Section 414(l) of the Code, Treasury Regulation Section 1.414(l)-1, and Section 208 of ERISA. Subject to the generally applicable requirements of this Section 3.01(b)(ii), the named fiduciaries (as such term is defined in ERISA) of the Aptevo 401(k) Plan and the Emergent 401(k) Plan shall cooperate in good faith to effect the transfers contemplated by this Section 3.01(b)(ii) in an efficient and effective manner and in the best interests of participants and beneficiaries, including, but not limited to, determining whether and to what extent any investments held under the Emergent 401(k) Plan (other than participant loans) shall be liquidated prior to the transfer date to enable the value of such investments to be transferred to the Aptevo 401(k) Plan in cash or cash equivalents.

(A)with respect to aggregate annual, lifetime, or similar maximum benefits available under the Aptevo Health and Welfare Plans, a Transferred Employee’s prior claim experience under the Emergent Health and Welfare Plans and any Benefit Plan that provides leave benefits; or

(B)any eligible expenses incurred by a Transferred Employee and his or her covered dependents during the portion of the plan year of the applicable Emergent Health and Welfare Plan ending on the Distribution Date to be taken into account under such Aptevo Health and Welfare Plan for purposes of satisfying all deductible, coinsurance, and maximum out-of-pocket requirements applicable to such Transferred Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such Aptevo Health and Welfare Plan.

(c)Allocation of Health and Welfare Assets and Liabilities.

(i)General Principles.  Except as otherwise specifically provided in this Agreement, Emergent shall retain all Liabilities relating to Incurred Claims under the Emergent Health and Welfare Plans, and shall also retain Assets (including, without limitation, Medicare reimbursements, pharmaceutical rebates, and similar items) associated with such Incurred Claims.  Aptevo shall be responsible for all Liabilities relating to Incurred Claims under any Aptevo Health and Welfare Plan and shall also retain Assets (including, without limitation, Medicare reimbursements, pharmaceutical rebates, and similar items) associated with such Incurred Claims.

For the avoidance of doubt, Emergent shall be responsible for the Incurred Claims of any Aptevo Employee for long-term disability benefits to the extent the claim was incurred prior to the Distribution Date and any Aptevo Employee with such an Incurred Claim for long-term disability benefits shall be eligible to receive benefits under the applicable Emergent long term disability plan notwithstanding his or her having become a Transferred Employee.

(i)Except as set forth on Schedule 5.01, outstanding Emergent Options and Emergent RSUs shall be treated as set forth in this Section 5.01. The Parties shall use commercially reasonable efforts to take all actions necessary or appropriate so that each outstanding Emergent Option and Emergent RSU award granted under an Emergent Stock Program (other than the awards described on Schedule 5.01) shall be adjusted as set forth in this Section 5.01.

(iii)No award described in this Article V, whether outstanding or to be issued, adjusted, substituted or cancelled by reason of or in connection with the Distribution, shall be adjusted, settled, cancelled, or exercisable, until in the judgment of the administrator of the applicable plan or program such action is consistent with all applicable Laws, including U.S.  securities Laws.  Neither the period of exercisability nor the term of any award will be extended on account of a period during which such an award is not exercisable pursuant to the preceding sentence.  

11

(iv)The adjustment or conversion of Emergent Options and Emergent RSUs shall be effectuated in a manner that is intended to avoid the imposition of any penalty or other taxes on the holders thereof pursuant to Section 409A of the Internal Revenue Code.

(i)Each Emergent Option that is outstanding as of the Effective Time that is held by an Emergent Employee or other Emergent Business service provider shall remain an option to purchase Emergent Common Shares and shall be adjusted as described below to reflect the Distribution.  Each such Adjusted Emergent Option shall be subject to the same terms and conditions after the Effective Time as the terms and conditions applicable to the corresponding Emergent Option immediately prior to the Effective Time; provided, however, that from and after the Effective Time: (x) the per-share exercise price of each such Adjusted Emergent Option shall be equal to the product of (I) the per-share exercise price of the corresponding Emergent Option immediately prior to the Distribution Date multiplied by (II) the Emergent Price Ratio, rounded up to the nearest whole cent; and (y) the number of Emergent Common Shares subject to each such Adjusted Emergent Option shall be equal to the product of (I) the number of Emergent Common Shares subject to each such Adjusted Emergent Option immediately prior to the Effective Time multiplied by (II) the Emergent Share Ratio, with any fractional shares rounded down to the nearest whole share.  

(ii)Each Emergent Option that is outstanding as of the Effective Time that is held by an Aptevo Employee or other Aptevo Business service provider shall be converted into an option to purchase Aptevo Common Shares and shall be adjusted as described below to reflect the Distribution.  Each such Aptevo Option shall be subject to the same terms and conditions after the Effective Time as the terms and conditions applicable to the corresponding Emergent Option immediately prior to the Effective Time; provided, however, that from and after the Effective Time: (x) the per-share exercise price of each such Aptevo Option shall be equal to the product of (I) the per-share exercise price of the corresponding Emergent Option immediately prior to the Effective Time multiplied by (II) the Aptevo Price Ratio, rounded up to the nearest whole cent; and (y) the number of Aptevo Common Shares subject to each such Aptevo Option shall be equal to the product of (A) the number of Emergent Common Shares subject to the corresponding Emergent Option immediately prior to the Effective Time multiplied by (B) the Aptevo Share Ratio, with any fractional share rounded down to the nearest whole share.  

(c)RSUs.  

(i)Each award of Emergent RSUs held by an Emergent Employee or other Emergent Business service provider immediately prior to the Effective Time shall be adjusted, effective as of the Effective Time, by multiplying the number of Emergent Common Shares subject to each such award of Emergent RSUs by the Emergent Share Ratio, which product shall be rounded up to the nearest whole number of units.  Each Adjusted Emergent RSU shall be subject to the same terms and conditions after the Effective Time as the terms and conditions applicable to the corresponding Emergent RSU immediately prior to the Effective Time.

12

(ii)Each award of Emergent RSUs held by an Aptevo Employee or other Aptevo Business service provider immediately prior to the Effective Time shall be converted to a restricted unit award relating to a number of Aptevo Common Shares determined by multiplying the number of Emergent Common Shares subject to each such award of Emergent RSUs by the Aptevo Share Ratio, which product shall be rounded up to the nearest whole number of Aptevo RSUs.  Except as otherwise provided herein, each Aptevo RSU shall be subject to the same terms and conditions after the Distribution as the terms and conditions applicable to the corresponding Emergent RSUs immediately prior to the Distribution. 

(d)Liabilities for Settlement of Awards.
