ARTICLE 2

SEPARATION OF ASSETS; DISTRIBUTION OF HIPPORX

Section 2.01. Timing of HippoRx Distribution. On the Closing Date, Hippo and HippoRx shall consummate the HippoRx Distribution at the Distribution Time. As used herein, “Closing Date” means the date on which the Distributions and the Mergers become effective, which date shall be mutually agreed by Hippo and Rhino and shall be a date occurring as soon as practicable (and in any event, within five Business Days (assuming that each of the HippoRx Working Capital and the RhinoRx Working Capital have been finally determined in accordance with Annex A, or if not so determined, within five Business Days after such final determination)) after satisfaction or, to the extent permitted hereunder, waiver of all conditions set forth in Article 13 (other than conditions that by their nature are to be satisfied on the Closing Date and will in fact be satisfied on the Closing Date).

Section 2.02. Transfer of Assets; Assumption of Liabilities.

(a) Subject to Section 2.03, as of the Distribution Time, (i) the right, title and interest in all HippoRx Assets will be owned by the HippoRx Entities and (ii) all HippoRx Liabilities will be the obligation of the HippoRx Entities. Prior to the Distribution Time, subject to Section 2.03, Hippo and the HippoRx Entities shall take all such actions as are necessary or appropriate (including executing and delivering such bills of sale, assignments, deeds, stock powers, certificates of title and instruments of assumption) to cause (i) the HippoRx Entities to own all of the HippoRx Assets and (ii) the HippoRx Entities to assume and be subject to all of the HippoRx Liabilities.

(b) Subject to Section 2.03, as of the Distribution Time, (i) the right, title and interest in all Non-HippoRx Assets will be owned and retained by Hippo or its Subsidiaries (other than the HippoRx Entities) and (ii) all Non-HippoRx Liabilities will be the obligation of Hippo or its Subsidiaries (other than the HippoRx Entities). Prior to the Distribution Time, subject to Section 2.03, Hippo and the HippoRx Entities shall take all such actions as are necessary or appropriate (including executing and delivering such bills of sale, stock powers, certificates of title and instruments of assumption) to cause (i) Hippo or its Subsidiaries (other than the HippoRx Entities) to own all of the Non-HippoRx Assets and (ii) Hippo or its Subsidiaries (other than the HippoRx Entities) to assume and be subject to all of the Non-HippoRx Liabilities.

(c) In the event that at any time or from time to time (whether prior to or after the Closing Date) Hippo or HippoRx (or any of their respective Subsidiaries) shall receive or otherwise possess any Asset that is allocated to any other Person pursuant to this Agreement, subject to Section 2.03, such party shall promptly transfer, or cause to be transferred, such Asset to the Person so entitled thereto. Prior to any such transfer, the Person receiving or possessing such Asset shall hold such Asset in trust for any such other Person.

Section 2.03. Governmental Approvals; Consents.

(a) If and to the extent that the valid, complete and perfected transfer or assignment to HippoRx of any HippoRx Assets or to Hippo of any Non-HippoRx Assets as contemplated by Section 2.02 would be a violation of Applicable Law or require any Consent or Governmental Approval, then the applicable transfer or assignment shall be automatically deemed deferred and any such purported transfer or assignment shall be null and void until such time as all legal impediments are removed and/or such Consents or Governmental Approvals have been obtained. Notwithstanding the foregoing, any such Asset shall be deemed an Asset of the transferee for purposes of determining whether any Liability is a Liability of the transferee.

(b) If the transfer or assignment of any Asset intended to be transferred or assigned hereunder is not consummated prior to or at the Closing Date, whether as a result of the provisions of Section 2.03(a) or for any other reason, then the Person retaining such Asset shall thereafter hold such Asset for the use and benefit, insofar as reasonably possible, of the Person entitled thereto (at the expense of the Person entitled thereto). In addition, the Person retaining such Asset shall take such other actions as may be reasonably requested by the Person to whom such Asset is to be transferred in order to place such Person, insofar as reasonably possible, in the same position as if such Asset had been transferred as contemplated hereby and so that all the benefits and burdens relating to such Asset, including possession, use, risk of loss, potential for gain, and dominion, control and command over such Asset, inure from and after the Closing Date to the Person to whom such Asset is to be transferred. To the extent permitted by Applicable Law and to the extent otherwise permissible in light of any required Consent and/or Governmental Approval, the Person to whom such Asset is to be transferred shall be entitled to, and shall be responsible for, the management of any Asset not yet transferred to it as a result of this Section and the parties agree to use commercially reasonable efforts to cooperate and coordinate with respect thereto.

(c) If and when the Consents and/or Governmental Approvals, the absence of which caused the deferral of transfer of any Asset pursuant to Section 2.03(a), are obtained, the transfer of the applicable Asset shall be effected in accordance with the terms of this Agreement.

(d) The Person retaining an Asset due to the deferral of the transfer of such Asset shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced by the Person entitled to the Asset, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by the Person entitled to such Asset.

Section 2.04. Termination of Agreements.

(a) Except as set forth in Section 2.04(b), effective as of the Closing Date, Hippo, for itself and each of its Subsidiaries (other than the HippoRx Entities), on the one hand, and HippoRx, for itself and each other HippoRx Entity, on the other hand, hereby terminate any and all agreements, arrangements, commitments or understandings, whether or not in writing, between or among Hippo and/or any of its Subsidiaries (other than the HippoRx Entities), on the one hand, and HippoRx and/or any other HippoRx Entity, on the other hand. No such terminated agreement, arrangement, commitment or understanding (including any provision thereof that purports to survive termination) shall be of any further force or effect after the Closing Date. Each of Hippo and HippoRx shall, at the reasonable request of any other party, take, or cause to be taken, such other actions as may be necessary to effect the foregoing, including having its Subsidiaries execute such additional instruments, if any, as shall be necessary to effect the foregoing.

(b) The provisions of Section 2.04(a) shall not apply to any of the following agreements, arrangements, commitments or understandings (or to any of the provisions thereof):

(i) the Transaction Agreements and each other agreement or instrument expressly contemplated by any of the Transaction Agreements to be entered into by the parties thereto or any of their Affiliates;

(ii) any agreement, arrangement, commitment or understanding listed on Section 2.04(b)(ii) of the Hippo Disclosure Schedule;

(iii) any intercompany accounts settled in accordance with Section 9.03; and

(iv) any other agreements, arrangements, commitments or understandings that any of the agreements listed in clause (i) or (ii) expressly contemplates will survive the Closing Date.

Section 2.05. HippoRx Distribution.

(a) At the Distribution Time, Hippo will deliver to the Exchange Agent for the benefit of holders of record of Hippo Common Stock (other than Hippo Common Stock held by Hippo in its treasury or Hippo Common Stock held by any Subsidiary of Hippo) on the Record Date, a single stock certificate, endorsed by Hippo in blank, representing the shares of HippoRx Common Stock issuable in the HippoRx Distribution (which shall constitute all of the shares of HippoRx Common Stock outstanding as of the Closing Date), and shall cause the transfer agent for the shares of HippoRx Common Stock to instruct the Exchange Agent to hold in trust (pending conversion of such shares of HippoRx Common Stock into shares of Newco Common Stock pursuant to the HippoRx Merger) the appropriate number of such shares of HippoRx Common Stock (as set forth in

Section 2.05(b)) for each such holder or designated transferee or transferees of such holder.

(b) Each holder of Hippo Common Stock (including Hippo Restricted Stock) on the Record Date will be entitled to receive in the HippoRx Distribution a number of shares of HippoRx Common Stock equal to (i) 100 divided by the number of shares of Hippo Common Stock outstanding on the Record Date multiplied by (ii) the number of shares of Hippo Common Stock held by such holder on the Record Date.

(c) Hippo and HippoRx, as the case may be, will provide to the Exchange Agent all share certificates and any information reasonably required in order to complete the HippoRx Distribution on the basis specified above.

(d)(i) Prior to the cash distribution described below and the transactions described in Section 2.05(a), Section 2.05(b) and Section 2.05(c), HippoRx shall cause Hippo Operating Sub to transfer all of the outstanding shares of the Hippo Retained Subsidiaries to Hippo or a Subsidiary of Hippo (other than a HippoRx Entity) and (ii) following the transfer described in clause (i) and immediately prior to the transactions described in Section 2.05(a), Section 2.05(b) and Section 2.05(c), HippoRx shall make a cash distribution to Hippo in the amount of the HippoRx Final Financing Amount that is not used to pay intercompany account balances pursuant to Section 9.03.

All fractional shares of Newco Common Stock that a holder of shares of HippoRx Common Stock or RhinoRx Common Stock would otherwise be entitled to receive pursuant to the Mergers shall be aggregated, and if a fractional share results from such aggregation, in lieu of receiving such fractional share, a shareholder will be entitled to receive, from the Exchange Agent and in accordance with the provisions of this Section 6.03, a cash payment representing such shareholder’s proportionate interest, if any, in the net proceeds from the sale by the Exchange Agent in one or more transactions (which sale transactions shall be made at such times, in such manner and on such terms as the Exchange Agent shall determine in its reasonable discretion) on behalf of all such shareholders of the aggregate of the fractional shares of Newco Common Stock which otherwise would have been distributed to such shareholders (the “Excess Shares”). The sale of the Excess Shares by the Exchange Agent shall be executed on the New York Stock Exchange through one or more member firms of the New York Stock Exchange and shall be executed in round lots to the extent practicable. Until the net proceeds of such sale or sales have been distributed to such shareholders, the Exchange Agent will hold such proceeds in trust for such shareholders. Newco shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including, without limitation, the expenses and compensation of the Exchange Agent, incurred in connection with such sale of the Excess Shares. As soon as practicable after the determination of the amount of cash, if any, to be paid to such shareholders in lieu of any fractional shares of Newco Common Stock, the Exchange Agent shall make available such amounts to such shareholders without interest.

Section 6.04. Adjustments Related to IRS Ruling. Notwithstanding anything to the contrary herein, the parties hereto (i) will reasonably cooperate, including by making any necessary and reasonable modifications to the provisions of this Agreement and (ii) to the extent necessary and permitted under Applicable Law, will amend or modify the terms of any applicable equity incentive plan, program, arrangement or agreement, in each case in order to obtain the private letter rulings from the Internal Revenue Service described in Section 13.02(c) and Section 13.03(c); provided, however, that neither Hippo nor Rhino shall be required to make any amendments which would require the approval of its stockholders; provided, further, that to the extent any such amendment requires the consent of participants in any applicable plan, Hippo or Rhino, as the case may be, will use, and shall not be required by anything herein to use more than, its reasonable best efforts to obtain such consent. If necessary, modifications to Section 6.03 could include only pooling and selling the Excess Shares of record holders of HippoRx Common Stock and RhinoRx Common Stock in the sale made pursuant to Section 6.03. In addition, in the event that any party hereto has any reasonable basis, based on either formal or informal discussions with the Internal Revenue Service, to believe that the Internal Revenue Service will not

issue any of the private letter rulings described herein, such party shall use reasonable best efforts to notify the other parties hereto.

Section 6.05. Withholding Rights. Newco shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 6 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If Newco so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of HippoRx Common Stock or RhinoRx Common Stock, as the case may be, in respect of which Newco made such deduction and withholding.

Section 6.06. Transferring Hippo Employee Stock Options.

(a) With respect to outstanding Hippo Stock Options held by Active Transferring Hippo Employees, for purposes of each applicable employee stock option plan, compensation plan, individual award agreement or other arrangement of Hippo, the employment of each Active Transferring Hippo Employee shall be deemed to have terminated without cause immediately following the HippoRx Distribution. Each outstanding Hippo Stock Option held by an Active Transferring Hippo Employee (each, a “Transferring Hippo Option”) that is vested as of the Distribution Time shall remain exercisable for Hippo Common Stock for the period of time following the Closing Date as permitted by, and in accordance with, its terms and conditions. Each Transferring Hippo Option that is unvested as of the Distribution Time shall cease to represent a right with respect to a share of Hippo Common Stock and shall be deemed to be converted in the HippoRx Distribution into an option to purchase shares of HippoRx Common Stock (each, a “HippoRx Stock Option”), on the same terms and conditions as applied to such Transferring Hippo Option immediately before the Distribution Time. At the Effective Time, each deemed HippoRx Stock Option shall cease to exist and shall be automatically converted into an option to purchase Newco Common Stock (each, a “Newco Stock Option”) on the same terms and conditions as applied to the original Transferring Hippo Option immediately before the Distribution Time and Newco shall assume each such Newco Stock Option. The exercise price and number of shares of Newco Common Stock subject to such Newco Stock Option shall be determined in accordance with Section 424 of the Code as follows: (i) the number of shares of Newco Common Stock subject to each such Newco Stock Option shall be equal to the product of (x) the number of shares of Hippo Common Stock subject to the original unvested Transferring Hippo Option and (y) the Newco Share Ratio, with fractional shares rounded down to the nearest whole share and (ii) the per-share exercise price of such Newco Stock Option shall be equal to the product of (x) the per-share exercise price of the original unvested Transferring Hippo Option immediately prior to the Distribution Time and (y) the Newco Price Ratio, rounded up to the nearest whole cent.

(b) Prior to the Closing Date, Hippo shall use its reasonable best efforts (i) to obtain any consents from Active Transferring Hippo Employees and (ii) to make any amendments to the terms of such stock option or compensation plans or arrangements that, in either case, are necessary to give effect to the transactions contemplated by this Section 6.06; provided, however, Hippo shall not be required to make any amendments which would require the approval of its stockholders; provided, further, that to the extent any such amendment requires the consent of participants in any applicable plan, Hippo shall use its reasonable best efforts to obtain such consent.

Section 6.07. Transferring Rhino Employee Stock Options.

(a) With respect to outstanding Rhino Stock Options held by Active Transferring Rhino Employees, for purposes of each applicable employee stock option plan, compensation plan, individual award agreement or other arrangement of Rhino, the employment of each Active Transferring Rhino Employee shall be deemed to have terminated without cause immediately following the RhinoRx Distribution. Each outstanding Rhino Stock Option held by an Active Transferring Rhino Employee (each, a “Transferring Rhino Option”) that is vested as of the Distribution Time shall remain exercisable for Rhino Common Stock for the period of time following the Closing Date as permitted by, and in accordance with, its terms and conditions. Each Transferring Rhino Option that is unvested as of the Distribution Time shall cease to represent a right with respect to a share of Rhino Common Stock and shall be deemed to be converted in the RhinoRx Distribution into an option to purchase shares of RhinoRx Common Stock (each, a “RhinoRx Stock Option”), on the same terms and conditions as applied to such Transferring Rhino Option immediately before the Distribution Time. At the Effective Time, each deemed RhinoRx Stock Option shall cease to exist and shall be automatically converted into a Newco Stock Option on the same terms and conditions as applied to the original Transferring Rhino Option immediately before the Distribution Time and Newco shall assume each such Newco Stock Option. The exercise price and number of shares of Newco Common Stock subject to such Newco Stock Option shall be determined in accordance with Section 424 of the Code as follows: (i) the number of shares of Newco Common Stock subject to each such Newco Stock Option shall be equal to the product of (x) the number of shares of Rhino Common Stock subject to the original unvested Transferring Rhino Option and (y) the Newco Share Ratio, with fractional shares rounded down to the nearest whole share and (ii) the per-share exercise price of such Newco Stock Option shall be equal to the product of (x) the per-share exercise price of the original unvested Transferring Rhino Option immediately prior to the Distribution Time and (y) the Newco Price Ratio, rounded up to the nearest whole cent.

(b) Prior to the Closing Date, Rhino shall use its reasonable best efforts (i) to obtain any consents from Active Transferring Rhino Employees and (ii) to make any amendments to the terms of such stock option or compensation plans or arrangements that, in either case, are necessary to give effect to the transactions

contemplated by this Section 6.07; provided, however, Rhino shall not be required to make any amendments which would require the approval of its stockholders; provided, further, that to the extent any such amendment requires the consent of participants in any applicable plan, Rhino shall use its reasonable best efforts to obtain such consent.

Section 6.08. Restricted Stock.

(a) Each holder of Hippo Restricted Stock outstanding on the Record Date shall receive the same number of shares of Newco Common Stock by virtue of the HippoRx Distribution and the Merger as a holder of Hippo Common Stock on the terms and conditions set forth in the applicable sections of Article 2 and this Article 6. Any shares of Newco Common Stock received by the holder of Hippo Restricted Stock shall be subject to the same terms regarding vesting and lapse of restrictions as were applicable to the Hippo Restricted Stock. Each holder of Rhino Restricted Stock outstanding on the Record Date shall receive the same number of shares of Newco Common Stock by virtue of the RhinoRx Distribution and the Merger as a holder of Rhino Common Stock on the terms and conditions set forth in the applicable sections of Article 2 and this Article 6. Any shares of Newco Common Stock received by a holder of Rhino Restricted Stock shall be fully vested. For purposes of each equity incentive plan or arrangement of Hippo or Rhino under which Hippo Restricted Stock or Rhino Restricted Stock, as applicable, was granted, the employment of each Active Transferring Rhino Employee and each Active Transferring Hippo Employee shall be deemed to have terminated without cause immediately following the RhinoRx Distribution or the HippoRx Distribution, as applicable. Each share of Hippo Restricted Stock held by an Active Transferring Hippo Employee and each share of Rhino Restricted Stock held by an Active Transferring Rhino Employee that is outstanding on the Closing Date shall be automatically cancelled at the Effective Time for no consideration, as provided for in the applicable equity incentive plan or arrangement of Hippo or Rhino, as applicable, and substituted with Newco Restricted Stock as set forth below. Newco shall grant to each Active Transferring Hippo Employee and each Active Transferring Rhino Employee who held Hippo Restricted Stock or Rhino Restricted Stock, as applicable, that was cancelled at the Effective Time as provided herein, a substitution grant of Newco Restricted Stock issued under the Newco Incentive Plan or such other equity incentive plan sponsored and maintained by Newco, on the same terms and conditions as applied to such award of Hippo Restricted Stock or Rhino Restricted Stock, as applicable, immediately prior to the Effective Time. Each such grant of Newco Restricted Stock shall have an equivalent value to the value of the cancelled Hippo Restricted Stock or Rhino Restricted Stock, as applicable, based on the value of a share of Hippo Common Stock or Rhino Common Stock, as applicable, immediately prior to the Effective Time and a share of Newco Common Stock immediately following the Effective Time and in each case without regard to any restrictions or periods of restriction to which such Restricted Stock is subject.

(b) Prior to the Closing Date, each of Hippo and Rhino shall make any amendments to the terms of the applicable equity incentive plans or restricted stock grants that, in either case, are necessary to give effect to the transactions contemplated by this Section 6.08; provided, however, that neither Hippo nor Rhino shall be required to make any amendments which would require the approval of its stockholders; provided, further, that to the extent any such amendment requires the consent of participants in any applicable plan, Hippo or Rhino, as the case may be, shall use, and shall not be required by anything herein to use more than, its reasonable best efforts to obtain such consent.

Section 6.09. Newco Actions. Newco shall take such actions as are necessary to effect the transactions contemplated by Section 6.06, Section 6.07 and Section 6.08 hereof, including, without limitation, adoption of an equity incentive plan (the “Newco Incentive Plan”), the receipt of shareholder approval with respect to such plan prior to the Distributions to the extent necessary to comply with NYSE (or NASDAQ, if applicable) shareholder approval rules, and the reservation, issuance and listing of Newco Common Stock. Newco shall prepare and file with the SEC a registration statement on an appropriate form with respect to the shares of Newco Common Stock subject to such equity awards and shall use its reasonable best efforts to have such registration statement declared effective as soon as practicable following the Effective Time and to maintain the effectiveness of such registration statement covering such equity awards (and to maintain the current status of the prospectus contained therein) for so long as such equity awards remain outstanding. With respect to those individuals, if any, who, subsequent to the Effective Time, will be subject to the reporting requirements under Section 16(a) of the 1934 Act, where applicable, Newco shall use all reasonable efforts to administer the Newco Incentive Plan in a manner that complies with Rule 16b-3 promulgated under the 1934 Act.

(f) The obligations of Newco, the HippoRx Surviving Corporation and the RhinoRx Surviving Corporation shall not be terminated or modified in such a manner as to adversely affect the rights of any D&O Indemnified Person to whom this Section 11.12 applies unless (x) such termination or modification is required by Applicable Law or (y) the affected D&O Indemnified Person shall have consented in writing to such termination or modification (it being expressly agreed that the D&O Indemnified Persons to whom this Section 11.12 applies shall be third party beneficiaries of this Section 11.12).

Section 11.13. Stock Exchange Listing. Newco, Hippo and Rhino shall use their respective reasonable best efforts to cause the shares of Newco Common Stock to be issued in connection with the Mergers to be listed on the NYSE (or, if listing on the NYSE is not approved or appears impracticable, the NASDAQ Stock Market), subject to official notice of issuance.

Section 15.02(a) shall not apply to any breach of the representation contained in Section 7.08(b).

(b) Subject to Section 15.02(c), effective at and after the Effective Time, Rhino hereby indemnifies the Newco Indemnified Parties against, and agrees to hold each of them harmless from, any and all Damages actually incurred or suffered by such Newco Indemnified Party arising out of, relating to or resulting from (i) subject to the next sentence, any Warranty Breach by Rhino; (ii) any Covenant Breach by Rhino; or (iii) the Non-RhinoRx Group, the Non-RhinoRx Assets or the Non-RhinoRx Liabilities.

For the avoidance of doubt, to the extent Damages are recoverable because of a breach of the representation in Section 7.08(b), Damages shall not be recoverable pursuant to a claim of indemnification for a breach of any other representation or warranty of Hippo in this Agreement. For the avoidance of doubt, Damages recoverable for breach of the representation in Section 7.08(b) include diminution in value, if any, of the Hippo Institutional Pharmacy Business as a result of such breach.

(e) Effective at and after the Effective Time, Rhino hereby indemnifies the Newco Indemnified Parties against, and agrees to hold each of them harmless from, any and all Damages actually incurred or suffered by such Newco Indemnified Party arising out of, relating to or resulting from, any misrepresentation or breach of warranty by Rhino of the representation in Section 8.08(b).

(i) None of Hippo, Rhino or Newco shall be liable to any Newco Indemnified Party, Hippo Indemnified Party or Rhino Indemnified Party, as the case may be, for any punitive, incidental, consequential, special or indirect damages, including business interruption or loss of future revenue, relating to the breach or alleged breach of this Agreement, except if such damages were paid by the applicable Indemnified Party to a Third Party and arose from circumstances that constituted a breach of a representation or warranty contained herein.

(j) The indemnification provisions contained in this Section 15.02 shall not apply to any misrepresentation or breach of warranty contained in Section 7.10(a)(xv), 7.15, 7.24, 8.10(a)(xv), 8.15 or 8.24, to any breach of the covenants contained in Section 9.01(n), 10.01(n), or 11.11, or to any Damages with respect to any Tax liability or Tax asset allocated to any Person pursuant to the Tax Matters Agreement.

Section 15.03. Indemnification Procedures.

(a) The party seeking indemnification under Section 15.02 (the “Indemnified Party”) agrees to give prompt notice to the party against whom indemnity is sought (the “Indemnifying Party”) of the assertion of any claim, or

120

the commencement of any suit, Action or proceeding (each, a “Claim”) in respect of which indemnity may be sought under such Section and will provide the Indemnifying Party such information with respect thereto that the Indemnifying Party may reasonably request. The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually materially prejudiced the Indemnifying Party.

(b) The Indemnifying Party shall have the right, at its option, exercisable within 30 days after receipt of such notice to assume the defense of, at its own expense and by its own counsel (which counsel shall be reasonably satisfactory to the Indemnified Party), any matter involving the asserted liability of the Indemnified Party (“Asserted Liabilities”), subject to the limitations set forth herein. If the Indemnifying Party shall undertake to compromise, settle or defend any such Asserted Liability, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party agrees to cooperate fully with the Indemnifying Party and its counsel in the compromise or settlement of, or defense against, any such Asserted Liability; provided, however, that the Indemnifying Party shall not settle any such Asserted Liability without the written consent of the Indemnified Party unless such settlement releases the Indemnified Party from all liabilities and obligations with respect to the Asserted Liability and the settlement does not impose injunctive or other equitable relief against the Indemnified Party. Notwithstanding an election by the Indemnifying Party to assume the defense of such action or proceeding, the Indemnified Party shall have the right to employ separate counsel and to participate in the defense of such action or proceeding at its own expense. Notwithstanding anything herein to the contrary, the Indemnifying Party shall not be entitled to assume control of such defense but shall pay for the reasonable fees, costs and expenses of the Indemnified Party’s legal counsel, which counsel shall be reasonably satisfactory to the Indemnifying Party, if (i) the claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (ii) the Indemnified Party has been advised by counsel that a reasonable likelihood exists of a conflict of interest between the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, or (iii) the Indemnifying Party failed or is failing to prosecute or defend such claim. If the Indemnified Party shall undertake to compromise, settle or defend any Asserted Liability in accordance with the immediately preceding sentence or after the Indemnifying Party has declined to exercise its option to assume the defense of an Asserted Liability, the Indemnified Party shall promptly notify the Indemnifying Party of its intention to do so, and the Indemnifying Party agrees to cooperate fully with the Indemnified Party and its counsel in the compromise or settlement of, or defense against, any such Asserted Liability; provided, however, that the Indemnified Party shall not settle any such Asserted Liability without the written consent of the Indemnifying Party, which such consent shall not be unreasonably withheld.

121

(c) Each party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Claim by a Third Party and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

Section 15.04. Calculation of Damages. Any Damages payable by an Indemnifying Party pursuant to Section 15.02 shall be (i) reduced by any proceeds recovered under applicable insurance policies, net of any costs incurred by the Indemnified Party in obtaining such proceeds, (ii) reduced by any indemnity, contribution or other similar payment paid to the Indemnified Party by any Third Party with respect to such Damages, net of any costs incurred by the Indemnified Party in obtaining such payment and (iii) reduced by an amount equal to any net tax benefit actually realized as a consequence of such Damages. If an Indemnified Party receives a payment required by this Agreement from an Indemnifying Party in respect of any Liability and subsequently receives insurance proceeds, then the Indemnified Party will pay to the Indemnifying Party an amount equal to the excess of the payment received over the amount of the payment that would have been due if the insurance proceeds had been received, realized or recovered before the payment was made by the Indemnifying Party.

Section 15.05. Release of Pre-Closing Claims.

(a) Except as provided in Section 15.05(c), effective as of the Effective Time, Newco, for itself, its Subsidiaries and each HippoRx Entity and RhinoRx Entity and their respective successors and assigns, and all shareholders, directors, officers, members, agents or employees of a HippoRx Entity or RhinoRx Entity (in each case, in their respective capacities as such), hereby remises, releases and forever discharges each of Hippo and Rhino and their respective Subsidiaries (other than the HippoRx Entities and the RhinoRx Entities, respectively), their respective successors and assigns, and all shareholders, directors, officers, members, agents or employees of any wholly owned member of Hippo or Rhino (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns, from any and all Liabilities whatsoever, whether at law or in equity (including any right of contribution), whether arising under any contract or agreement, by operation of law or otherwise, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed at or before the Effective Time, whether or not known as of the Effective Time, including in connection with the Transactions.

(b) Except as provided in Section 15.05(c), effective as of the Effective Time, each of Hippo and Rhino, for itself and each of its Subsidiaries (other than any HippoRx Entity or RhinoRx Entity) and their respective successors and assigns, and all shareholders, directors, officers, members, agents or employees of Hippo or Rhino or such Subsidiaries (in each case, in their respective capacities as such), hereby remises, releases and forever discharges each of Newco and its

122

Subsidiaries (including the HippoRx Entities and RhinoRx Entities), their respective successors and assigns, and all shareholders, directors, officers, members, agents or employees of Newco and such Subsidiaries (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns, from any and all Liabilities whatsoever, whether at law or in equity (including any right of contribution), whether arising under any contract or agreement, by operation of law or otherwise, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed at or before the Effective Time, whether or not known as of the Effective Time, including in connection with the Transactions.

(c) Nothing contained in Section 15.05(a) or Section 15.05(b) shall impair any right of any Person to enforce the Transaction Agreements or any agreements, arrangements, commitments or understandings that are specified in Section 2.04(b) or Section 3.04(b) as surviving the Closing Date, in each case in accordance with its terms. Nothing contained in Section 15.05(a) or Section 15.05(b) shall release any Person from:

(i) any Liability provided in or resulting from any agreement among Hippo or its Subsidiaries or Rhino or its Subsidiaries, on the one hand, and Newco, any HippoRx Entity or any RhinoRx Entity, on the other hand, that is specified in Section 2.04(b) or Section 3.04(b) as surviving the Closing Date, or any other Liability specified in such Sections as surviving the Closing Date; or

(ii) any Liability, contingent or otherwise, assumed, transferred, assigned or allocated to Hippo, Rhino, Newco, the HippoRx Entities, the RhinoRx Entities or any of their respective Subsidiaries in accordance with, or any other Liability of any such Person under, the Transaction Agreements.

(d) If an Indemnified Party receives any payment from an Indemnifying Party in respect of Damages and the Indemnified Party could have recovered all or a part of such Damages from a Third Party based on the underlying claim or demand asserted against such Indemnifying Party, then such Indemnified Party shall transfer such of its rights to proceed against such Third Party as are necessary to permit such Indemnifying Party to recover from such Third Party the amount of such payment.

Section 15.06. Exclusivity. After the Effective Time, Article 15 will provide the exclusive remedy for any claims by or against Newco or its Subsidiaries, on the one hand, or by or against Hippo, Rhino or any of their respective Subsidiaries or Affiliates, on the other hand, arising as a result of or in connection with this Agreement and the transactions contemplated hereby (other than any remedy provided in any of the other Transaction Agreements) except

123

that the indemnity provisions contained herein shall not limit any party’s liability for fraud or intentional misrepresentation.

Annex A – Adjustments

Section 1. Adjustment Procedures.

(a) Not later than 10 Business Days prior to the Closing Date, (i) Hippo shall submit to Rhino a certificate (the “HippoRx Estimate Certificate”) of an authorized officer of Hippo setting forth its good faith estimate of the HippoRx Working Capital (the “Estimated HippoRx Working Capital”) and (ii) Rhino shall submit to Hippo a certificate (the “RhinoRx Estimate Certificate”) of an authorized officer of Rhino setting forth its good faith estimate of the RhinoRx Working Capital (the “Estimated RhinoRx Working Capital”). The amounts set forth on the HippoRx Estimate Certificate and the RhinoRx Estimate Certificate, as the case may be, shall be calculated in accordance with GAAP on a basis consistent with the applicable audited financial statements in the Registration Statement and shall be accompanied by appropriate information and documentation in reasonable detail supporting the calculations of the Estimated HippoRx Working Capital and the Estimated RhinoRx Working Capital, as the case may be.

(b) Following receipt of the HippoRx Estimate Certificate by Rhino and the RhinoRx Estimate Certificate by Hippo, Hippo and Rhino shall work in good faith to mutually agree on the amounts of the HippoRx Working Capital and the RhinoRx Working Capital. If Hippo and Rhino are unable to agree on the amounts of the HippoRx Working Capital or the RhinoRx Working Capital, as the case may be, within 3 Business Days following delivery of both certificates, each of Hippo and Rhino shall submit a notice (each such notice, a “Disagreement Notice”) to a mutually satisfactory nationally recognized accounting firm (the “Accounting Referee”) specifying those items or amounts as to which they each disagree. The Disagreement Notices shall set forth the nature and basis for each disagreement with respect to the HippoRx Working Capital or the RhinoRx Working Capital, as the case may be. Rhino shall be deemed to have agreed with all items and amounts on the HippoRx Estimate Certificate (as such items and amounts may have been modified by mutual agreement of Hippo and Rhino) that Rhino does not contest in its Disagreement Notice. Hippo shall be deemed to have agreed with all items and amounts on the RhinoRx Estimate Certificate (as such items and amounts may have been modified by mutual agreement of Hippo and Rhino) that Hippo does not contest in its Disagreement Notice.

(c) Hippo and Rhino shall use their reasonable best efforts to cause the Accounting Referee to promptly review this Agreement and the disputed items or amounts for the purpose of determining the HippoRx Working Capital and the RhinoRx Working Capital. The Accounting Referee shall deliver to Hippo and Rhino, as promptly as practicable (but in no event more than 5 Business Days after its receipt of the Disagreement Notices), a report setting forth its determination of the HippoRx Working Capital and the RhinoRx Working

A-1

Capital. In making such determination, the Accounting Referee shall consider only those items or amounts as to which Hippo and Rhino disagree, as set forth on their respective Disagreement Notices, and the Accounting Referee’s determination as to each disputed item or amount shall be neither more nor less than the amounts set forth by Hippo and Rhino on their respective Disagreement Notices. The report of the Accounting Referee and the determinations of the Accounting Referee as to the HippoRx Working Capital and the RhinoRx Working Capital shall be final and binding upon Hippo and Rhino. All fees and expenses of the Accounting Referee shall be borne equally by Hippo and Rhino.
