 ARTICLE 3 
 PAYMENT OF TAXES 
 Section 3.01. Responsibility of
Rhino. Rhino shall be liable for and shall timely pay, or cause to be paid, to the applicable Taxing Authority all Taxes required to be paid with respect to all Rhino Income Tax Returns and RhinoRx Non-Income Tax Returns. No Tax sharing payments
shall be made by members of the Newco Group to members of the Rhino Group, or by members of the Rhino Group to members of the Newco Group, with respect to the Rhino Income Tax Returns. 
 Section 3.02. Responsibility of Hippo. Hippo shall be liable for and shall timely pay, or cause to be paid, to the applicable Taxing
Authority all Taxes required to be paid with respect to all Hippo Income Tax Returns and HippoRx Non-Income Tax Returns. No Tax sharing payments shall be made by members of the Newco Group to members of the Hippo Group, or by members of the Hippo
Group to members of the Newco Group, with respect to the Hippo Income Tax Returns. 
 Section 3.03. Responsibility of Newco.
Newco shall timely pay, or cause to be paid, to the applicable Taxing Authority all Taxes required to be paid with respect to all Newco Tax Returns. The tax liability with respect to any Newco Straddle Period Tax Return shall be apportioned
among Newco, Rhino and Hippo in a manner that reasonably reflects the portion of such tax liability attributable to Newco for the Post-Closing Tax Period, the RhinoRx Entities for the Pre-Closing Tax Period and the HippoRx Entities for the
Pre-Closing Tax Period. In the case of any Tax that is imposed on a periodic basis and is payable with respect to a Newco Straddle Period Tax Return, the portion of such Tax related to the Pre-Closing Tax Period shall (x) in the case of any Tax
other than gross receipts, sales or use Taxes and Taxes based upon or related to income, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the Tax period ending
on and including the Closing Date and the denominator of which is the number of days in the entire Tax period; provided, however, that the portion of any such Tax attributable to the Pre-Closing Tax Period shall be computed as if the Transactions
did not occur and, therefore, any increase to the valuation of property that arises due to the Transactions shall not cause an increase in the Tax attributable to the Pre-Closing Tax Period and (y) in the case of any Tax based upon or related
to income and any gross receipts, sales or use Tax, be deemed equal to the amount which would be payable if the relevant Tax period ended on and included the Closing Date. All determinations necessary to give effect to the foregoing allocations
shall be made in a manner consistent with prior practice of the Person that has incurred such Tax. Rhino and Hippo, as the case may be, shall reimburse Newco for any Taxes that Newco pays with respect to any Newco Straddle Period Tax Return which is
allocable to RhinoRx or Hippo Rx, respectively, under this Section. 
  

 12 

 ARTICLE 4

Newco shall promptly pay or cause to be paid to Rhino all such refunds received by any member of the Newco Group. If (i) in lieu of receiving any such refund any member of the Newco Group reduces a Tax liability with respect to a Post-Closing
Tax Period or increases a Tax Asset that can be carried forward to a Post-Closing Tax Period or (ii) as a result of an increase in Tax liability with respect to a Rhino Income Tax Return or a RhinoRx Non-Income Tax Return, any member of the
Newco Group reduces a Tax liability with respect to a Post-Closing Tax Period or increases a Tax Asset with respect to a Post-Closing Tax Period, Newco shall promptly pay or cause to be paid to Rhino the amount of such reduction in Tax liability or

for Hippo. Hippo shall be entitled to all refunds and credits of Taxes, including any interest thereon, paid with respect to Hippo Income Tax Returns and HippoRx Non-Income Tax Returns. Newco shall promptly pay or cause to be paid to Hippo all
such refunds received by any member of the Newco Group. If (i) in lieu of receiving any such refund any member of the Newco Group reduces a Tax liability with respect to a Post-Closing Tax Period or increases a Tax Asset that can be carried
forward to a Post-Closing Tax Period or (ii) as a result of an increase in Tax liability with respect to a Hippo Income Tax Return or a HippoRx Non-Income Tax Return, any member of the Newco Group reduces a Tax liability with respect to a
Post-Closing Tax Period or increases a Tax Asset with respect to a Post-Closing Tax Period, Newco shall promptly pay or cause to be paid to Hippo the amount of such reduction in Tax liability or the amount of any benefit resulting from such increase
in Tax Assets, as the case may be. 
 Section 4.03. Refunds with Respect to Newco Straddle Period Tax Returns. All refunds and
credits of Taxes, including any interest thereon, paid with respect to Newco Straddle Period Tax Returns shall be apportioned among Newco, Rhino and Hippo in a manner that fairly reflects the apportionment principle in Section 3.03. Rhino,
Hippo, or Newco, as the case may be, shall promptly pay or cause to be paid to each of the other Parties its apportioned share of each such refund or credit. 
  

 13 

 Section 4.04. Carryforwards and Carrybacks. To the extent permitted by Applicable Law, Newco
shall (or shall cause or permit the members of the Newco Group to) elect to relinquish any carryback of a Tax Asset to any Pre-Closing Tax Period. No Party shall be obligated to compensate any other Party for the carryforward of Tax Assets from a
Pre-Closing Tax Period to a Post-Closing Tax Period or for the carryback of Tax Assets from a Post-Closing Tax Period to a Pre-Closing Tax Period.
