ARTICLE II VALUATION

2.1    Ending Valuation; Determination of Value Creation.

(a)    The Ending Valuation shall be:

(i)    as mutually agreed by Theta and GRA promptly following the Value Creation Date; or

(ii)    if mutual agreement between Theta and GRA on the Ending Valuation is not reached with sixty (60) days following the Value Creation Date, each of Theta and GRA shall determine its own calculation of Value Creation Payment and

if, between such two Value Creation Payment calculations, (a) the lower calculation is 10% or less below the higher calculation, the average of the two calculations is the final Value Creation Payment, or (b) the lower calculation is more than 10% below the higher calculation, the Valuation Firm (as selected in accordance with the next sentence) will determine its calculation of the Value Creation Payment, which calculation shall (x) not be higher than the higher calculation presented by the two parties and not be lower than the lower calculation presented by the two parties and (y) be averaged with the calculation that is closer to the calculation of the Valuation Firm and the final Value Creation Payment shall equal such average. If the foregoing clause (b) is implicated, a Valuation Firm shall be mutually agreed to by Theta and GRA promptly following the Value Creation Date (in any event, the Valuation Firm shall be chosen and charged with the Value Creation determination within 90 days following the Value Creation Date; provided, that if GRA and Theta cannot agree upon such a Valuation Firm, each such party shall select, within ten (10) days following the expiration of the sixty (60) day period referred to above, a nationally recognized, independent valuation firm and those valuation firms shall, within an additional ten (10) day period, jointly select another nationally recognized, independent valuation firm, which firm shall be the Valuation Firm for purposes of the determining the final Value Creation Payment), in accordance with this Section 2.1(a)(ii) and the standard valuation metrics and methodologies for independent alternative investment asset management businesses as set forth in Section 2.1(b).

(b)    The Ending Valuation shall be calculated using standard valuation metrics and methodologies for independent alternative investment asset management businesses, including, but not limited to:

(i)    public trading multiples analysis including alternative asset management firms with material similarities to OHA in one or more of their business characteristics, operational characteristics and/or financial metrics. The multiples shall be based on relevant closing stock prices for appropriate periods as close to the Value Creation Date as practicable, and financial data for the selected companies shall be based on the selected companies’ public filings, analyst research estimates and other publicly available information;

(ii)    selected comparable M&A transactions analysis including transactions that occurred within a period deemed relevant and whereby the businesses involved in such transactions operated in materially similar industries and/or had materially similar financial profiles to OHA; and

(iii)    discounted cash flow analysis based upon an OHA forecast of unlevered free cash flows. An appropriate discount rate shall be determined

based on a weighted average cost of capital for firms that are materially comparable to the OHA Business as of the Value Creation Date.

For illustrative purposes, Appendix A hereto sets forth sample valuation calculations.

2.2    Affiliate Transactions.    The parties agree that, during the Value Creation Period, GRA and Theta shall agree on the pricing of any Significant Affiliate

Transaction at or prior to the entry into such Significant Affiliate Transaction; provided, that if GRA and Theta are unable to agree on the pricing of any such Significant Affiliate Transaction, the parties agree that the pricing of such Significant Affiliate Transaction for purposes of determining the Ending Valuation, the Value Creation and the Value Creation Payment shall be determined in accordance with Section 2.1, with the Valuation Firm being entitled to make adjustments to such pricing as they determine appropriate under the circumstances in the context of determining the Ending Valuation, which adjustments could include considering what the pricing for such Significant Affiliate Transaction would have been on an arm’s-length basis with an unaffiliated third party. The Ending Valuation shall be adjusted to the extent necessary to reflect the difference between the pricing so determined in accordance with Section 2.1 and the pricing actually used between OHA and Theta.

ARTICLE III

VALUE CREATION PAYMENT

3.1    Value Creation Payment. The total amount payable to the Participants (the “Value Creation Payment”) shall be 10% of the Value Creation. The amount of the Value Creation Payment shall be calculated and agreed upon pursuant to the process and methodology set forth in Section 2.1 herein.

(b)    Within thirty (30) days following the determination of the Value Creation Payment pursuant to Section 3.1, an Acceleration Event or an Adjusted Value Creation Payment for which there was not previously a Value Creation Payment, GRA shall provide Theta with a schedule (an “Allocation Schedule”) setting forth the allocation of the Value Creation Payment or Accelerated Payment, as applicable, among the Participants as determined in his sole discretion.

(c)    If, following the Value Creation Date, OHA or its direct and/or indirect securityholders actually receives any Contingent Consideration, then Theta shall recalculate the Value Creation as of the Value Creation Date to include such Contingent Consideration in the computation of Ending Valuation as if such Contingent Consideration had been received prior to the Value Creation Date (the “Adjusted ValueCreation”) and furnish such calculation to the Senior Partners, which Adjusted Value Creation shall be finally determined in accordance with Section 2.1. Theta shall pay to the Participants an amount equal to 10% of the Value Creation Adjustment (the “AdjustedValue Creation Payment”) within five (5) Business Days of the final determination of the Adjusted Value Creation in accordance with the previously delivered Allocation Schedule in respect of the Value Creation Payment (if any) and Section 3.4.

3.3    Timing of Payment. Upon the satisfaction of the Value Creation Condition and within five (5) Business Days following receipt of an Allocation Schedule, Theta shall pay or cause to be paid the Value Creation Payment or Acceleration Payment, as applicable, to the Participants in accordance with such Allocation Schedule.

3.4    Form of Payment. Payment of the Value Creation Payment, Acceleration Payment or Adjusted Value Creation Payment, as applicable, to each Participant shall be made:

(a)    75% of the portion of the Value Creation Payment, Acceleration Payment or Adjusted Value Creation Payment, as applicable, allocated to such Participant in the Allocation Schedule in cash via payroll (subject to applicable withholding); and

(b)    by the issuance to such Participant of a number of shares (which shares shall be duly authorized, duly and validly issued, fully paid and non- assessable and not subject to, or issued in violation of, any purchase option, call option, right of first refusal, preemptive right, subscription right or any similar right under Theta’s Organizational Documents or any Contract to which Theta or any of its Subsidiaries is a party or otherwise bound) of T. Rowe Price Group, Inc. stock (“Theta Stock”) having an aggregate value (as determined pursuant to the next sentence) equal to 25% of the Value Creation Payment, Acceleration Payment or Adjusted Value Creation Payment, as applicable, allocated to such Participant in the Allocation Schedule and subject to vesting on terms to be determined by GRA upon delivery of the Allocation Schedule. The value of such Theta Stock shall be calculated as the arithmetic average of the VWAP for the Theta Stock for the five (5) consecutive Trading Days ending on the date immediately prior to the date the Value Creation Payment is made (subject to adjustment for any splits, combinations or reclassifications).
