Section 5.5 Fees and Expenses. All fees and expenses incurred in connection with this Agreement and the Exchanges (whether consummated or not), including the fees and disbursements of counsel, financial advisors and accounts, shall be paid by the Party incurring such fees or expenses.

Section 5.6 Construction. The headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement. The Parties hereto have voluntarily agreed to define their rights, liabilities and obligations respecting the Exchanges exclusively in contract pursuant to the express terms and provisions of this Agreement. The Parties each hereby acknowledge that this Agreement is among sophisticated parties derived from arm’s length negotiations and each party to this Agreement specifically acknowledges that no Party has a special relationship with another Party that would justify any expectation beyond that of an ordinary buyer and an ordinary seller in an arms-length transaction. No Party, nor its respective counsel, shall be deemed the drafter of this Agreement for purposes of construing the provisions hereof, and all provisions of this Agreement shall be construed according to their fair meaning and not strictly for or against any Party and no presumption or burden of proof will arise favoring or disfavoring any Person by virtue of its authorship of any provision of this Agreement. The words “dollar” or “$” shall mean United States dollars.

Section 5.7 Parties in Interest. This Agreement shall be binding upon and inure to the benefit of each Party and its successors and permitted assigns and, nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement.

Section 5.8 Extension; Waiver. Any agreement on the part of any Party to an extension of the time for the performance of any of the obligations or other acts under this Agreement or waiver of compliance with any of the agreements under this Agreement shall be valid only if set forth in a written instrument signed on behalf of such Party. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 5.9 Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the Exchange is not affected in any manner materially adverse to any Party hereto. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the Parties shall negotiate in good faith to modify this Agreement to replace any such provision with a valid and enforceable provision giving effect to the original intent of the Parties as closely as possible in an acceptable manner in order that the Exchanges are consummated as originally contemplated to the greatest extent possible.

12

Section 5.10 Counterparts; Electronic Signatures. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by e-mail (scanned pages) shall be effective as delivery of a manually executed original counterpart to this Agreement and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.

Section 5.11 Governing Law. This Agreement (but not, for the avoidance of doubt, the Sportradar Contribution Agreement and any Sportradar Subscription Form) shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware.

Section 5.12 Jurisdiction and Venue. Each of the Parties (a) submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) in any Proceeding arising out of or relating to this Agreement, its performance or subject matter, (b) agrees that all claims in respect of such Proceeding may be heard and determined in any such court and (c) agrees not to bring any Proceeding arising out of or relating to this Agreement in any other courts. Each of the Parties waives any defense of inconvenient forum to the maintenance of any Proceeding so brought and waives any bond, surety or other security that might be required of any other Party with respect thereto. Each Party agrees that service of summons and complaint or any other process that might be served in any Proceeding may be made on such Party by sending or delivering a copy of the process to the Party to be served at the address of the Party and in the manner provided for the giving of notices in Section 5.4. Nothing in this Section 5.12, however, shall affect the right of any Party to serve legal process in any other manner permitted by Law. Each Party agrees that a final, non-appealable judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law.

Section 5.13 WAIVER OF JURY TRIAL. EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY HEREBY FURTHER AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 5.14 Remedies. The Parties acknowledge and agree that irreparable harm for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that it does not fully and timely perform its obligations under or in connection with this Agreement in accordance with its terms. Each Party acknowledges and agrees that (a) the other Party shall be entitled to an injunction, specific performance or other equitable relief, to prevent breaches of this Agreement and to enforce

13

specifically the terms and provisions hereof, without proof of damages and without posting a bond, this being in addition to any other remedy to which such Party is entitled under this Agreement and (b) the right to obtain an injunction, specific performance, or other equitable relief is an integral part of the Exchanges and without that right, none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at law.

Section 5.15 Termination. For the avoidance of doubt, if the Merger Agreement is terminated in accordance with its terms, this Agreement shall be of no force or effect and the transactions contemplated hereby will not occur.

EXHIBIT D

RESTRICTIONS ON AGGREGATOR UNITS AND/OR

SHARES OF SPORTRADAR STOCK HELD BY EMPLOYEES

Management Equity Terms

These Management Equity Terms (these “Terms”) constitute the terms under which the members of management and other key employees (collectively, “Holders”) of Atrium Sports, Inc. and its subsidiaries (collectively, the “Company”) will, in connection with the acquisition (the “Acquisition”) of the Company by Sportradar Holding AG (“Sportradar”) pursuant to (and subject to the terms and conditions of) that certain Agreement and Plan of Merger by and among the Company, Sportradar and certain other parties (the “Merger Agreement”), the Contribution and Exchange Agreement and the other applicable Ancillary Agreements (each as defined therein), reinvest and/or contribute a portion of their Company shares and/or Acquisition-related proceeds in Sportradar participation certificates (“Sportradar Shares”). Capitalized terms not defined herein shall have the meanings set forth in the Merger Agreement. Certain Holders will hold their Sportradar Shares through Andretti Management Aggregator, LLC (“Management Aggregator”) and other Holders will hold their shares through Atrium Founders Pty Ltd. (“Founder Aggregator” and, together with Management Aggregator, the “Aggregators”).

Sportradar Public Company Event	Upon the occurrence of a Sportradar Public Company Event (as defined below), the Aggregators will receive shares in the applicable publicly listed entity (“Public Issuer Shares”). Such Public Issuer Shares will be subject to the vesting and repurchase provisions set forth below. Vested Public Issuer Shares will be distributed to the Holders immediately upon Vesting. Unvested Public Issuer Shares will be retained by the Aggregators until vesting.
Vesting	Each Holder’s interests in the Aggregators (“Aggregator Units”) (and the corresponding Sportradar Shares held by the Aggregators) will, upon the closing of the Acquisition, be unvested and will vest only as set forth below, in each case subject to the Holder’s continued service with Sportradar or one of its subsidiaries through the applicable date of vesting. Each time a portion of the Aggregator Units becomes vested, a corresponding portion of the Sportradar Shares held by the Aggregators shall become vested.
	100% of the Aggregator Units will remain unvested until an Exit or a Sportradar Public Company Event (each as defined below) occurs. Upon the occurrence of an Exit, all Aggregator Units shall become vested, provided, however, that 25% of the Aggregator Units will vest only if the performance conditions set forth in Exhibit A hereto are attained prior to the Exit; provided, further, that, to the extent the Exit occurs prior to when such performance conditions are to be measured, unvested Aggregator Units attributable to such performance conditions shall become vested upon the occurrence of such Exit. Aggregator Units that fail to vest in accordance with the preceding sentence in connection with an Exit will be forfeited, and the corresponding portion of the Sportradar Shares held by the Aggregators will be transferred and assigned to Sportradar (or an assignee thereof), in each case, immediately following the date on which the non-attainment of the relevant performance conditions has been determined in accordance with Exhibit A hereto, for no consideration.
	Upon the occurrence of a Sportradar Public Company Event, an initial percentage of the Public Issuer Shares (and each Holder’s corresponding Aggregator Units) shall vest as of the date of such Sportradar Public Company Event (the “Public Vesting Shares”), as provided in the table below:

	Amount of SR Pub Event
Year of SR Pub Event	Date Vesting
2021		35	%
2022		53	%
2023		71	%
2024		88	%

Following the Sportradar Public Company Event, the Public Issuer Shares (and corresponding Aggregator Units) that are not Public Vesting Shares shall vest in equal installments on each December 31 (beginning with December 31 of the year following the year of the Sportradar Public Company Event unless the Sportradar Public Company Event occurs in 2024) until December 31, 2024, such that all Public Issuer Shares (and corresponding Aggregator Units) will be vested as of December 31, 2024.

Notwithstanding the foregoing, 25% the Public Issuer Shares that are eligible to vest after the Sportradar Public Company Event date (i.e., on December 31 of subsequent years) shall be subject to the attainment of the performance conditions set forth in Exhibit A hereto. The Public Issuer Shares subject to such performance conditions under different Sportradar Public Company Event timing assumptions is as set forth below:

Time of Vesting	Total % Vesting			Of which performance based			Of which non- performance based
Vesting Scheme if Sportradar Public Company Event in 2021
at SR Pub Event		35.00	%		0.00	%		35.00	%
12/31/2022		22.00	%		5.50	%		16.50	%
12/31/2023		22.00	%		5.50	%		16.50	%
12/31/2024		21.00	%		5.25	%		15.75	%
Vesting Scheme if Sportradar Public Company Event in 2022
at SR Pub Event		53.00	%		4.50	%		48.50	%
12/31/2023		24.00	%		6.00	%		18.00	%
12/31/2024		23.00	%		5.75	%		17.25	%
Vesting Scheme if Sportradar Public Company Event in 2023
at SR Pub Event		71.00	%		9.00	%		62.00	%
12/31/2024		29.00	%		7.25	%		21.75	%
Vesting Scheme if Sportradar Public Company Event in 2024
at SR Pub Event		88.00	%		13.25	%		74.75	%
12/31/2024		12.00	%		3.00	%		9.00	%

	Any Public Issuer Shares that fail to vest as a result of the failure to attain the relevant performance conditions will be forfeited and are to be transferred and assigned to Sportradar (or an assignee thereof) immediately following the date on which the non-attainment of the relevant performance conditions has been determined in accordance with Exhibit A hereto for no consideration.
Leaver Events	Unvested Aggregator Units held by any Holder (and the corresponding Sportradar Shares or Public Issuer Shares, as applicable, held by the Aggregators) shall be further

subject to the following provisions (the “Leaver Provisions”) upon such Holder’s termination of service with Sportradar or any of its affiliates:

Prior to an Exit or Sportradar Public Company Event, (i) a Good Leaver (as defined below) shall have his or her Aggregator Units repurchased, at the election of Sportradar, for Fair Market Value as of the date of his or her Good Leaver Event and (ii) a Bad Leaver (as defined below) shall have his or her Aggregator Units repurchased, at the election of Sportradar, for the lesser of (i) Fair Market Value of such Aggregator Units at such time, or (ii) 50% of the Sportradar Share Deal Value multiplied by the number of such Aggregator Units. Any such repurchase shall occur in a process whereby Sportradar (or an assignee thereof) will repurchase Aggregator’s applicable Sportradar Shares for cash, and Aggregator will redeem the applicable Aggregator Units with a payment of such cash to such Holder or in a similar process.

Following an Exit, the Leaver Provisions shall no longer apply.

Following a Sportradar Public Company Event, Leaver Provisions shall only apply to unvested Public Issuer Shares (and corresponding Aggregator Units). A Good Leaver shall fully vest in his or her Aggregator Units and the corresponding Public Issuer Shares, and a Bad Leaver shall, at the election of Sportradar, have his or her unvested Public Issuer Shares (and corresponding Aggregator Units) repurchased for the lesser (i) Fair Market Value of such Public Issuer Shares at such time, or (ii) 50% of the Sportradar Share Deal Value multiplied by the number of such Aggregator Units. Any such repurchase shall occur in a process whereby Sportradar (or an assignee thereof) will repurchase Aggregator’s applicable Public Issuer Shares for cash, and Aggregator will redeem the applicable Aggregator Units with a payment of such cash to such Holder or in a similar process.

Notwithstanding the foregoing, the remuneration committee may, in its direction, determine a higher repurchase price for Public Issuer Shares (and corresponding Aggregator Units) held by a Bad Leaver or may determine not to repurchase such shares.

“Bad Leaver” shall mean a Holder who experiences a Bad Leaver Event.

“Bad Leaver Event” shall mean when a Holder (i) terminates his or her employment with Sportradar or any of its affiliates or (ii) is terminated by Sportradar or any of its affiliates for Cause. For purposes of this definition, the term “Sportradar” shall include the Company.

“Good Leaver Event” shall mean when a Holder (i) is terminated by Sportradar or any of its affiliates without Cause, (ii) retires from Sportradar or any of its affiliates upon reaching ordinary statutory retirement age, where applicable (iii) terminates employment with Sportradar or any of its affiliates as a result of death or Disability, or (iv) becomes subject to divorce proceedings (unless such proceedings are shown to not affect such Holder’s Sportradar Shares or Public Issuer Shares, as applicable). For purposes of this definition, the term “Sportradar” shall include the Company.

Definitions	“Blackbird” shall mean Blackbird Holdco Ltd or any other entity through which CPPIB may invest or hold equity interests directly or indirectly in Sportradar.
	“Cause” shall mean a Holder’s:
	i.   willful refusal (other than due to physical or mental incapacity) to substantially perform his or her duties or to carry out the reasonable and lawful instructions concerning duties or actions consistent with such Holder’s position that is not cured within 30 days after such Holder receives written notice thereof from Sportradar or any of its affiliates;
	ii.  material violation of a Sportradar policy that is not cured within 30 days after such Holder receives written notice thereof from Sportradar or any of its affiliates;
	iii.   material breach of any material agreement with Sportradar or any of its affiliates that is not cured within 30 days after such Holder receives written notice thereof from Sportradar or any of its affiliates;
	iv.   conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or crime involving moral turpitude; or
	v.  commission of any act of fraud, embezzlement, willful misappropriation, or willful misconduct against Sportradar.
	For purposes of this definition of “Cause”, the term “Sportradar” shall include the Company.
	“Change of Control” shall mean either of (i) a direct or indirect sale—in one or more related transactions—of more than 50% of the share capital of Sportradar or any intermediate Sportradar holding company or (ii) a merger or any other event (including a Trade Sale) following or as a result of which any person (or group of persons acting in concert) other than Blackbird or Carsten Koerl, is or becomes the direct or indirect beneficial owner of more than 50% of the share capital of Sportradar or any intermediate Sportradar holding company.
	“CPPIB” shall mean CPP Investment Board Europe S.a.r.l. and any of its applicable affiliates or successors.
	“Exit” shall mean the completion of a Trade Sale resulting in a Change of Control or a Trade Sale by way of asset deal.
	“Fair Market Value” shall mean, absent manifest error, (i) prior to January 1, 2025, the value most recently determined by Sportradar’s remuneration committee and derived from the valuation prepared for the fund reporting purposes of CPPIB, provided that no discount shall be made for reason of illiquidity and minority holding and that the valuation is made in Euro, and (ii) on or after January 1, 2025, fair market value as of the applicable time of determination assuming a sale of all of the equity interests of Sportradar (and not applying any minority discount or the like), as most

EXHIBIT A

PERFORMANCE CONDITIONS

Twenty-five percent (25%) the Public Issuer Shares that are eligible to vest after the Sportradar Public Company Event date shall be subject to the attainment of the performance conditions as set out in the following.

1. General framework

Performance will be measured along four (4) key performance indicators (“KPI”s). Target levels for each of the KPIs have been or will be defined for each of Sportradar’s financial years up to 2024. In order to assess if performance conditions are met, each KPI will be assigned a contribution factor based on its achievement level within a given financial year and subsequently weighted in order to derive its overall contribution to the total KPI achievement score. The sum of the individual KPI achievement scores will then determine the total KPI achievement score and thus the percentage of Public Issuer Shares eligible to vest as a result of the attainment of the performance conditions.

2. Key performance indicators

Based on the Holders’ and Sportradar’s current understanding of the Company’s business objectives and strategy, the parties have defined the below mentioned KPIs and associated targeted levels. It is, however, the understanding of both parties that different KPIs and associated target levels will need to be defined and agreed by the Vesting SteerCo (and confirmed in writing) should the Company’s future business objectives and strategy change. This will, in particular, apply to the 2024 KPIs and target levels which have not yet been defined.

Moreover the parties agree that if KPI #1 and KPI #2 are creating a significant conflict to be achieved together, the parties will discuss in good faith of how to amend KPI #2 with the clear understanding that the revenue targets from KPI #1 stay in place

2.1. KPI #1 – US college revenue KPIs

The US college revenue KPI target levels for each financial year are defined as follows:

	KPI #1 -US College Revenue

DII-Juco College max churn KPI target		105			114			122			tbd
Implied DII-Juco churn rate target		<5	%		<5	%		<5	%		<5	%

3. Achievement levels, contribution factors and KPI weightings

Each KPI will be assigned a contribution factor based on its achievement level within a given financial year and subsequently weighted in order to derive its overall contribution to the total KPI achievement score as provided in the table below:

KPI	Weighting			Min achievement level	Contribution factor
KPI #1 – US college revenue		70	%	0-89% 90-119.9% 120%+	0% 90-119.9% 120%
KPI #2 – US college camera installation		15	%	0-89% 90-119.9% 120%+	0% 90-119.9% 120%
KPI #3 – D1 US college max churn		10	%	0 - Not-achieved 1 - Achieved	0% 100%
KPI #4 – DII-Juco US college max churn		5	%	0 - Not-achieved 1 - Achieved	0% 100%

4. Achievement scores

All individual KPI achievement scores will then, in sum, determine the total KPI achievement score which subsequently determines the percentage of Public Issuer Shares eligible to vest as provided in the table below:

KPI Achievement score	% Vested
0-79%		0
80-90%		50	%
90-100%		75	%
100%+		100	%

5. Applicability of achieved KPI scores in different vesting schemes

The percentage of Public Issuer Shares eligible to vest will be derived based on achieved KPI scores in each financial year and as provided in the table below:

Time of Vesting	Total % Vesting			Of which performance based			Of which non- performance based			Triggers of performance based vesting

6. Other

Sportradar, the Board of Managers of Andretti Management Aggregator, LLC and the Board of Directors of Atrium Founders Pty Ltd. agree to form a Vesting Steering Committee (“Vesting SteerCo”) to regularly review the definition of the KPIs and their respective target levels to assess if they are still aligned with the Company’s business purpose, objectives, and strategy. If no mutual agreement is reached on changing KPI metrics and targets, previously agreed KPIs and targets shall be retained and applied.

Sportradar reserves the right to waive KPI and/or performance requirements (i.e. although KPIs may not be met, Sportradar, in its sole discretion, can cause Public Issuer Shares to vest).

The parties acknowledge and agree that KPIs and associated target levels for financial year 2024 shall be defined by the Vesting SteerCo and confirmed in writing no later than 31 December 2023.

Exemplary calculation

Exemplary calculation under the assumption of different achievement levels

KPI	Weighting			Achieved*			Contribution%
KPI #1		70	%		106	%		74.2	%
KPI #2		15	%		125	%		18.0	%
KPI #3		10	%		1			10.0	%
KPI #4		5	%		0			0.0	%
TOTAL (KPI Achievement Score):								102	%

KPI #1: The Company generates USD 18m US college revenue in the financial year 2021 which implies an achievement level of 106% versus the target KPI. This achievement level will be weighted by the overall US college revenue KPI weight of 70% to derive the contribution of this KPI to the overall achievement score. In this case, the US college revenue KPI will contribute 74.2% (i.e. 106% multiplied by 70%) to the total KPI achievement score.

KPI #2: The Company installs 132 US college cameras in the financial year 2021 which implies an achievement level of 125% versus the target KPI. This achievement level will be weighted by the overall US college revenue KPI weight of 15% to derive the contribution of this KPI to the overall achievement score. In this case, the US camera installation KPI will contribute 18.0% (i.e. 120% multiplied by 15%) to the total KPI achievement score.

KPI #3: The Company reports a churn of 20 D1 US college teams (on account of reasons other than school closures or team dissolution) in the financial year 2021 and has thereby satisfied the D1 US college max churn target (i.e. less than 28 D1 US college teams have churned). In this case, the D1 College minimum retention KPI will contribute 10.0% to the total KPI achievement score.

KPI #4: The Company reports a churn of 107 DII-Juco US college teams (on account of reasons other than school closures or team dissolution) in the financial year 2021 and has thereby not satisfied the DII-Juco US college max churn target (i.e. less than 105 DII-Juco team have churned). In this case, the DII-Juco College maximum churn KPI will not contribute to the total KPI achievement score.

The total resulting KPI achievement score amounts to 102% which triggers vesting of 100% of the Public Issuer Shares subject to the 2021 performance condition. For example, in case of a Sportradar Public Company Event in the financial year 2021; as at 31 December 2022, 2.75% (i.e., 50% of the 5.50% of performance based vesting at 31 December 2022) of the Public Issuer Shares would vest based on the achieved 2021 KPI score.
