WHEREAS, to support the ongoing operational integration of business practices and to enhance client and staff experiences at StepStone and SPD, the Parties desire to enter into this Transaction Agreement to facilitate the medium to long-term economic integration of the Parties;

WHEREAS, in furtherance of the purposes in the foregoing recital, the Parties intend for the Seller to exchange, in a series of transactions, the Seller’s equity interests in SPD for equity interests in STEP (or cash in lieu of a portion thereof) (collectively, the “Transactions”, and each such exchange, an “Exchange”);

WHEREAS, subject to the terms and conditions in this Agreement, including with respect to any Acceleration Exchange, Termination Acceleration Exchange and Change of Control Exchange (each as defined below), the Parties intend to consummate ten (10) annual Exchanges, with the first Exchange to be conducted with a reference date of April 1, 2024 (the “Initial Reference Date”) and to be consummated promptly following the Initial Reference Date upon the satisfaction or waiver of the conditions set forth in this Agreement applicable to such Exchange, and the nine (9) subsequent Exchanges to be conducted with a reference date of each of the nine (9) following anniversaries of the Initial Reference Date (such dates, together with the Initial Reference Date, each, a “Reference Date”) and to be consummated promptly following each applicable Reference Date upon the satisfaction or waiver of the conditions set forth in this Agreement applicable to such Exchanges;

WHEREAS, the Parties intend that, at the consummation of the tenth (10^th) Exchange or the Acceleration Exchange (as defined below), SSG (or its nominee) will own all of the outstanding equity interests of SPD; and

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Parties hereby agree as follows:

ARTICLE I

THE EXCHANGE

1.1 The Exchange.

(a) Upon the terms and subject to the conditions of this Agreement, at each Closing (as defined below), the Seller shall sell, convey, assign, transfer and deliver to SSG (or to its nominee), and SSG (or its nominee) shall purchase, acquire and accept from the Seller, all of the Seller’s right, title and interest in and to such amount of Equity Securities of SPD set forth in Schedule A attached hereto (the “Annual Exchange Schedule”) for the Reference Date of the relevant Exchange. For purposes of this Agreement, any Equity Securities of SPD exchanged pursuant to this Agreement may be referred to as the “Exchanged Securities”. The Exchanged Securities that are the subject of any Exchange shall correspond to the SCP Participations allocated among the SCP Partners in accordance with Section 1.9.

(b) In exchange therefor, at each Closing (except with respect to an Acceleration Exchange, which shall be governed by Section 1.6), SSG shall convey to the Seller the Adjusted Exchange Value by (i) pursuant to Section 1.3, delivering to the Seller an amount in cash equal to (x) the Reduced Exchange Value multiplied by the Cash Percentage for such Exchange, plus (y) the Fractional Equity Payment, and (ii) causing STEP to issue to the Seller the number of whole shares of STEP Class A Common Stock (rounded down to the nearest whole share of STEP Class A Common Stock) (the “Consideration Securities”) equal to (x) (A) the Adjusted Exchange Value less (B) the cash amount delivered pursuant to the foregoing clause (i)(x), divided by (y) the STEP 30-Day VWAP. Additionally, at the Closing of the Fifth Exchange (or, if applicable, an Acceleration Exchange), SSG shall make payment in cash to the Seller of the liquidation preference compensation amount in respect of the Exchanged Securities in such Exchange which are Preferred Shares CHF 100 (as set forth in Schedule A attached hereto), which shall be in an aggregate amount equal to CHF 4,860,863.50.

(c) In lieu of the issuance of any fractional share of STEP Class A Common Stock, if the Seller would otherwise have been entitled to a fractional share of STEP Class A Common Stock pursuant to the terms of this Agreement, then the Seller shall be paid cash, without interest (the “Fractional Equity Payment”), in an amount equal to (i) the fractional share of STEP Class A Common Stock to which the Seller would otherwise be entitled under Article I of this Agreement multiplied by (ii) the STEP 30-Day VWAP, and rounded to the nearest cent.

(d) Upon the terms and subject to the conditions of this Agreement, immediately prior to the Closing of the First Exchange, the Seller shall sell, convey, assign, transfer and deliver to SSG (or its nominee), and SSG (or its nominee) shall purchase, acquire and accept from the Seller, all of the Seller’s right, title and interest in and to such amount of Equity Securities of SPD as is set forth in the first column of Schedule B attached hereto (the

- 2 -

“SPD Swap Schedule”) in consideration for (i) the sale, conveyance, assignment, transfer and delivery by SSG (or an Affiliate of SSG) to the Seller of all of SSG’s (or SSG’s Affiliate, as applicable) right, title and interest in and to such amount of Equity Securities of SPD set forth in the second column of the SPD Swap Schedule and (ii) the payment in cash by SSG to the Seller of the liquidation preference compensation amount set out in the third column of the SPD Swap Schedule.

1.2 Closing.

(a) The closing of any Exchange (each a “Closing”) shall take place remotely via electronic exchange of documents and signatures, as promptly as practicable following, but in no event later than, the third (3^rd) Business Day after the satisfaction or waiver of each of the conditions set forth in Article II of this Agreement applicable to such Closing (other than, but subject to satisfaction of, the conditions to be satisfied on the applicable Closing Date); provided, however, in no event shall a Closing take place prior to the first (1^st) Business Day after the latest of (i) the last day of the determination period for the STEP 30-Day VWAP for such Exchange, (ii) the date on which STEP issues its audited financial statements for its latest fiscal year ending prior to the Closing (the “STEP Audited Financials”), and (iii) the date on which the Adjustment Statement is delivered in respect of the preceding Exchange. For purposes of this Agreement, the date of the Closing with respect to an Exchange may be referred to as the “Closing Date” of such Exchange, and the effective time of the Closing with respect to an Exchange may be referred as the “Effective Time” of such Exchange.

(b) The failure to consummate an Exchange on the date and time determined pursuant to Section 1.2(a) shall not result in the termination of this Agreement or relieve any Party of any of its obligations under this Agreement.

1.3 Cash Percentage. The Cash Percentage for each Exchange shall be twenty percent (20%). Subject to restrictions under applicable Law, any governance documents of STEP and SSG, and any credit agreement, loan agreement, note, indenture or other financing agreements under which STEP or SSG is bound, and subject to the receipt of any applicable stockholder or regulatory approval, SSG, at its sole discretion, shall use commercially reasonable efforts to deliver, or cause to be delivered, at Closing the cash portion of the Exchange Value (or, for each Exchange other than the first Exchange, the Reduced Exchange Value) that corresponds to the Cash Percentage; provided, that, to the extent SSG does not deliver, or cause to be delivered, all or a portion of such cash consideration, the cash portion of the Exchange Value for the relevant Exchange to be delivered pursuant to Section 1.1(b)(i)(x) shall be ratably reduced and, consequently, the number of Consideration Securities to be delivered pursuant to Section 1.1(b)(ii) shall be ratably increased.

1.4 Distribution Adjustments. It is intended that (a) any distributions made by SPD in respect of the Exchanged Securities with respect to any period (i) ending prior to the Reference Date for an Exchange will inure to the benefit of the Seller and (ii) commencing on or after the applicable Reference Date for an Exchange will inure to the benefit of SSG (or its nominee); and that (b) the Consideration Securities issued in such Exchange shall entitle the Seller to receive a cash payment in an amount equal in value to any distributions made by STEP in respect of such Consideration Securities with respect to any period commencing on or after the applicable Reference Date. Consistent with the foregoing, it is intended that any

- 3 -

distributions made in respect of the other Equity Securities that are transferred by (A) the Seller to SSG (or its nominee) pursuant to Section 1.1(d) with respect to any period (i) ending prior to the Reference Date for the First Exchange will inure to the benefit of the Seller and (ii) commencing on or after the applicable Reference Date for the First Exchange will inure to the benefit of SSG (or its nominee, as applicable) and (B) SSG (or its nominee) to the Seller pursuant to Section 1.1(d) with respect to any period (i) ending prior to the Reference Date for the First Exchange will inure to the benefit of SSG (or its nominee, as applicable) and (ii) commencing on or after the applicable Reference Date for the First Exchange will inure to the benefit of the Seller. In the event any such distributions are paid or made to a Person in a manner inconsistent with such intent, then the Parties shall make appropriate adjustments to the consideration delivered in such Exchange or in the subsequent Exchanges.

1.5 True-Up.

(a) Adjustment Statement. As soon as practicable, but in no event later than ten (10) days after each issuance of the STEP Audited Financials, SSG shall deliver to the Asset Class Head a statement (an “Adjustment Statement”) setting forth SSG’s re-calculation of the Exchange Value of the last Exchange by applying the Applicable SPD Multiple as of the preceding Reference Date to the actual Adjusted Net Income of SPD (rather than the SPD Budget ANI) used to prepare the STEP Audited Financials (such recalculated amount, the “Final Exchange Value”). An “Upward Adjustment Amount” shall exist to the extent (if any) of the positive difference between (w) the Final Exchange Value and (x) the Exchange Value originally calculated and used for such Exchange (the “Original Exchange Value”); and a “Downward Adjustment Amount” shall exist to the extent (if any) of the positive difference between (y) the Original Exchange Value and (z) the Final Exchange Value.

(b) Upward Adjustment. If an Upward Adjustment Amount exists, then STEP shall, at the Closing of the current year’s Exchange, (x) issue an additional amount of Consideration Securities (rounded down to the nearest whole Consideration Security) to the Seller equal to (A) the Upward Adjustment Amount divided by (B) the STEP 30-Day VWAP and (y) pay or cause to be paid to the Seller an amount of cash equal to the applicable Fractional Equity Payment. For the avoidance of doubt, any reference to Upward Adjustment Amount in this paragraph shall be a reference to the Upward Adjustment Amount with respect to the preceding Exchange.

(c) Downward Adjustment. If a Downward Adjustment Amount exists, then in the current year Exchange (x) the Reduced Exchange Value shall be decreased by the Downward Adjustment Amount and (y) the Adjusted Exchange Value shall equal the Reduced Exchange Value as adjusted pursuant to clause (x). To the extent the Reduced Exchange Value would fall below zero as a result of an adjustment pursuant to this Section 1.5(c), then, at SSG’s option, (i) the Seller shall promptly (and in any event within thirty (30) days) pay SSG an amount in cash equal to the remaining Downward Adjustment Amount or (ii) the remaining Downward Adjustment Amount shall be carried forward to the next succeeding future Exchange(s). To the extent any remaining balance of the applicable portion of any Downward Adjustment Amount exists immediately after the Closing of the final Exchange, the Seller shall promptly (and in any event within thirty (30) days) pay SSG or its designee an amount in cash equal to such remaining

- 4 -

balance. The Seller acknowledges and agrees that, in the event that the Seller does not timely pay SSG any cash amount payable by the Seller to SSG pursuant to this Section 1.5(c), SSG shall have the right to set off such cash amount against any dividends, distributions or other income allocations from SSG or its Affiliates to the Seller or its Affiliates and against any other amounts (including, to the extent permitted by applicable Law, employment compensation and expense reimbursements) otherwise payable by SSG or its Affiliates to the Seller or its Affiliates. For the avoidance of doubt, any reference to Downward Adjustment Amount in this paragraph shall be a reference to the Downward Adjustment Amount with respect to the preceding Exchange.

1.6 Acceleration Exchange.

(a) Acceleration Exchange. At any point following the Exchange with respect to the April 1, 2028 Reference Date, SSG and the Seller, acting with an SCP Partner Majority, may, by mutual agreement, elect to accelerate the remaining annual Exchanges in one final Exchange as of the Reference Date immediately following such election. If such election is so made, then the Seller shall sell and surrender all Equity Securities of SPD held by the Seller in such final Exchange. For purposes of this Agreement, such final Exchange may be referred to as the “Acceleration Exchange”.

(b) Holdback. At the Closing of the Acceleration Exchange, Consideration Securities representing fifty percent (50%) of the Reduced Exchange Value (the “Holdback”) shall not be issued by STEP but shall instead be held back to facilitate a true-up following the issuance of the STEP Audited Financials for the Final Projection Year. For the avoidance of doubt, the Holdback shall not include any cash consideration included in the Reduced Exchange Value. SSG shall pay to the Seller an amount equal to all dividends, distributions and other income with respect to fifty percent (50%) of the unissued Consideration Securities included in the Holdback (net of any withholding due under applicable law with respect to dividends, distributions and other income with respect to such Consideration Securities pursuant to Section 2.4) which payment shall be made at the same time as such dividends, distributions and other income are distributed or paid to the equityholders of STEP generally in accordance with the terms of STEP’s organizational documents; SSG shall pay to the Seller an amount equal to all dividends, distributions and other income with respect to the other fifty percent (50%) of the unissued Consideration Securities included in the Holdback (net of any withholding due under applicable law with respect to dividends, distributions and other income with respect to such Consideration Securities pursuant to Section 2.4), which payment shall be made at such time as, and to the extent, the Seller becomes entitled to such Consideration Securities.

(c) Acceleration Exchange Adjustment Statement. As soon as practicable, but in no event later than ten (10) days after the issuance of the STEP Audited Financials for the Final Projection Year, SSG shall deliver to the Asset Class Head a statement (the “Acceleration Exchange Adjustment Statement”) setting forth SSG’s re-calculation of the Exchange Value of the Acceleration Exchange by applying the Applicable SPD Multiple as of the Reference Date of the Acceleration Exchange to the Actual Acceleration SPD ANI (rather than Acceleration SPD Budget ANI) (such recalculated amount, the “Final Acceleration Exchange Value”). An “Upward Acceleration Exchange Adjustment Amount” shall exist to the extent (if any) of the positive difference between the Final Acceleration Exchange Value and the Exchange Value originally calculated and used for the Acceleration Exchange (the “Original Acceleration Exchange Value”); and a “Downward Acceleration Exchange Adjustment Amount” shall exist to the extent (if any) of the positive difference between the Original Acceleration Exchange Value and the Final Acceleration Exchange Value.

- 5 -

(d) No Adjustment. If the Final Acceleration Exchange Value equals the Original Acceleration Exchange Value, SSG shall promptly (and in any event within thirty (30) days of the date of determination of the Final Acceleration Exchange Value) release the Holdback to the Seller.

(e) Upward Acceleration Exchange Adjustment. If an Upward Acceleration Exchange Adjustment Amount exists, SSG shall promptly deliver or cause STEP to deliver to the Seller (i) the Holdback, (ii) cash equal to the Fractional Equity Payment, and (iii) a number of issued Consideration Securities (rounded down to the nearest whole Consideration Security) equal to (x) the Upward Acceleration Exchange Adjustment Amount (net of any Downward Adjustment carried forward pursuant to Section 1.5(c)), divided by (y) the STEP 30-Day VWAP.

(f) Downward Acceleration Exchange Adjustment. If a Downward Acceleration Exchange Adjustment Amount exists, SSG shall (i) retain for the account of STEP or SSG from the Holdback an amount equal to the Downward Acceleration Exchange Adjustment Amount (together with all dividends, distributions and other income with respect to the relevant unissued Consideration Securities) (the Holdback after such deduction, the “Adjusted Holdback”), and (ii) following the completion of step (i), promptly release the Adjusted Holdback, if any, to the Seller net of any Downward Adjustment carried forward pursuant to Section 1.5(c).

(g) Further Adjustment. In the event the Downward Acceleration Exchange Adjustment Amount exceeds the Exchange Value of the Holdback, the Seller shall promptly (and in any event within thirty (30) days) pay SSG an amount in cash equal to (i) the Downward Acceleration Exchange Adjustment Amount less (y) the Exchange Value of the Holdback. The Seller acknowledges and agrees that, in the event that the Seller does not timely pay SSG any cash amount payable by the Seller to SSG pursuant to this Section 1.6(g), SSG shall have the right to set off such cash amount against any dividends, distributions or other income allocations from SSG, STEP or their Affiliates to the Seller, the SCP Partners or their Affiliates and against any other amounts (including, to the extent permitted by applicable Law, employment compensation and expense reimbursements) otherwise payable by SSG or its Affiliates to the Seller, the SCP Partners or their Affiliates.

(h) Termination Acceleration Exchange. With respect to any SCP Partner who is terminated (with or without cause), resigns or retires (an “Acceleration Party”), the remaining Equity Securities in SPD held by the Seller that correspond to such SCP Partner’s equity interests in the Seller (on a look through basis) shall be treated as set forth in Annex C attached hereto.

(i) Change of Control Exchange. If a Change of Control of STEP or SSG shall occur, then the Exchanges provided for herein shall continue as scheduled; provided, that:

- 6 -

(i) the STEP Multiple for all Exchanges occurring on or after the date of the Change of Control shall be the lower of (x) 40 and (y) the STEP Multiple implied by the fair value (as determined in good faith by the Board of Directors of STEP (the “STEP Board”)) of the consideration paid in such Change of Control for each share of STEP Class A Common Stock or unit of SSG, as applicable; provided, however, that this Section 1.6(i)(i) shall be subject to Section 1.8, and the provisions relating to Skipped Exchanges shall apply, if the applicable STEP Multiple as determined in accordance with the foregoing is below 16; and

(ii) for the purposes of subsequent calculations of the Exchange Value, the Exchange Value shall be calculated based on the fair value (as determined in good faith by the STEP Board) of the consideration paid in such Change of Control for each share of STEP Class A Common Stock or unit of SSG, as applicable; and

(iii) the Exchange Value to be delivered to the Seller for Exchanges occurring on or after the effective date of the Change of Control shall be payable in the kind of securities, cash or other property paid in such Change of Control to other equityholders of STEP or SSG (such securities, cash or other property, the “Reference Property” and the amount and kind of Reference Property that a holder of one Consideration Security would be entitled to receive, a “Reference Property Security”); provided, that, (x) if the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of equityholder election, then the composition of the Reference Property Security shall be deemed to be the weighted average of the types and amounts actually received by the other equityholders of STEP or SSG in the Change of Control transaction, and (y) if the Reference Property consists of equity securities that are not Publicly Traded Securities, STEP and SSG shall use commercially reasonable efforts, acting in good faith, to structure the Change of Control transaction to avoid a disproportionate and materially adverse effect on the Seller relative to the other equityholders of STEP or SSG party to such Change of Control transaction.

1.7 Adjustment for Reclassification. If the number of outstanding Equity Securities of STEP or SPD has been changed into a different number of units or shares (as applicable) or a different class, including by reason of any reclassification, unit split (including a reverse unit split) or stock split (as applicable), recapitalization, split-up, combination, exchange of units or shares, readjustment or other similar transaction, or if a dividend or distribution thereon is declared, the relevant provisions of this Agreement shall be equitably adjusted to reflect such change so as to provide STEP, SSG and the Seller the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing in this Section 1.7 shall be deemed to permit or authorize SPD to effect any such change that it is not authorized or permitted to undertake.

1.8 Limitations on Exchanges.

(a) Notwithstanding the other provisions of this Article I, the Seller shall not be obligated to effect any Exchange if the STEP Multiple with respect to such Exchange is below 16 (such Exchange, a “Skipped Exchange”).

(b) Notwithstanding the provisions of this Article I, neither STEP nor SSG shall be obligated to effect any Exchange if, after giving effect to such Exchange, STEP and/or SSG would have issued, pursuant to the terms of this Agreement and/or the Other Transaction Agreements, more than an aggregate of 75 million Consideration Securities and/or Consideration Units (as such term is defined in each Other Transaction Agreement) (the “Aggregate Equity Limit”). To the extent an Exchange would otherwise result in the issuance of Consideration Securities in excess of the Aggregate

- 7 -

Equity Limit, STEP or SSG may, at its option and in its sole discretion, (i) increase the Cash Percentage for such Exchange so as to complete such Exchange without exceeding the Aggregate Equity Limit, or (ii) increase the Aggregate Equity Limit; provided that, upon the request of the Asset Class Head, STEP and/or SSG shall consider in good faith using its commercially reasonable efforts to effectuate the foregoing clause (ii) (and failing that, the foregoing clause (i)).

(c) For the avoidance of doubt, no Closing shall occur with respect to a Skipped Exchange, and the Seller shall not be required to sell, convey or deliver Equity Securities of SPD in connection with such Skipped Exchange.

(d) In the event of a Skipped Exchange, the Exchanged Securities that would otherwise have been subject to such Exchange (i) shall be subject to the next annual Exchange for which the STEP Multiple is equal to or greater than 16 or the Aggregate Equity Limit has not been exceeded, as applicable, (ii) the Exchange Value for such Exchanged Securities shall be calculated using the actual Adjusted Net Income of SPD (rather than SPD Budget ANI) for the fiscal year that was the subject of the Skipped Exchange and (iii) no true-up pursuant to Section 1.5 shall be made with respect to such Exchanged Securities.

1.9 Allocation Procedures. With respect to each Exchange, the Asset Class Head shall deliver to SSG an allocation notice (“Allocation Notice”), which shall set forth the proposed allocation of the Exchanged Securities set forth on the Annual Exchange Schedule opposite the applicable Reference Date of such Exchange among the SCP Participations of each SCP Partner, including the pro forma ownership of SCP Participations (and indirectly of Consideration Securities) by the SCP Partners as a result of such Exchange. The Allocation Notice will be delivered (i) with respect to the first Closing, within ten (10) days of the date of this Agreement, and (ii) with respect to any other Closing, no later than February 1^st of the corresponding year for the applicable Reference Date. SSG’s approval of the allocation proposed in any Allocation Notice shall be required only if such allocation does not conform to the programme set out in Schedule C attached hereto, and such approval by SSG shall not be unreasonably withheld; provided that, if SSG does not agree to such proposed allocation, then the SCP Participations subject to the relevant Exchange shall be reallocated to conform to such programme. The Asset Class Head shall promptly and in any event (x) with respect to the first Closing, within twenty (20) days of the date of this Agreement, and (y) with respect to any other Closing, prior to the applicable Reference Date, deliver an exchange notice (an “Exchange Notice”) to each SCP Partner, which shall set forth the amount of Exchanged Securities attributable to the SCP Participations of such SCP Partner in such Exchange. With respect to each Exchange, the Seller shall, reasonably promptly following the applicable Closing, distribute the applicable Consideration Securities and cash amounts to the applicable SCP Partners in accordance with the applicable allocation in redemption of the SCP Participations to which such Exchange is attributable (each such distribution, an “SCP Distribution”), and the Seller shall cause such changes in the SCP Participations as are appropriate to reflect the result of the Exchange and resulting SCP Distribution.
