000 Xxxxxxxxx Xxxxxx

Boston, MA 02116

Ladies and Gentlemen:

This letter agreement (this “Agreement”) sets forth the commitment of each of Xxxx Capital Fund XIII, L.P., a Delaware limited partnership, and Xxxx Capital Fund (Lux) XIII, SCSp, a special limited partnership organized and established under the laws of Grand Duchy of Luxembourg (each individually, a “Fund” and collectively, the “Funds”), to purchase, directly or indirectly, on the terms and subject to the conditions contained herein, certain equity interests of BCPE Polymath Buyer, Inc., a newly formed Delaware corporation (“Parent”), formed to acquire, hold and dispose of, directly or indirectly, equity interests of PowerSchool Holdings, Inc., a Delaware corporation (the “Company”), pursuant to the transactions contemplated by that certain Agreement and Plan of Merger (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), dated as of the date hereof, by and among Parent, the Company and BCPE Polymath Merger Sub, Inc., a Delaware corporation (“Merger Sub”). Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

1. Commitments. Each Fund hereby commits, severally and not jointly or jointly and severally, on the terms and subject to conditions set forth herein, at or prior to the Closing, to purchase, or shall cause the purchase of, directly or indirectly through one or more intermediate entities, equity securities of Parent for an aggregate purchase price not to exceed such Fund’s Pro Rata Percentage (as defined below) of $1,748,566,902 (as to each Fund, the “Individual Commitment Cap,” and in the aggregate, the “Commitment Amount”) (such commitment, the “Commitment”), the proceeds of which, together with the net proceeds of the Debt Financing, will be used, as needed, solely to (i) fund amounts required to be paid by Parent pursuant to the last sentence of Section 2.7(d), Section 2.8(e) and Section 2.9(b) of the Merger Agreement and (ii) without duplication, pay related fees, costs and expenses required to be paid by Parent or Merger Sub in connection with the Merger at the Closing pursuant to the Merger Agreement (collectively, clauses (i) and (ii), “Closing Payments”). Notwithstanding anything to the contrary in this Agreement, (a) this Agreement may not be enforced against any Fund without giving effect to its Individual Commitment Cap, and no Fund shall be liable for any amounts hereunder in excess of its Individual Commitment Cap, and (b) each Fund may allocate all or a portion of its Commitment to one or more affiliated investment funds, affiliated separately managed accounts or affiliated investment vehicles and such Fund’s portion of the Commitment Amount will be reduced by its Pro Rata Percentage of any amounts actually contributed to Parent by such other Persons (and not returned) at or prior to the Closing, so long as such assignment would not reasonably be expected to (i) prevent, impair or delay the consummation of the transactions contemplated by the Merger Agreement or (ii) require any additional regulatory filings, of which the failure to obtain would prevent, impair or delay the consummation of the transactions contemplated by the Merger

1

Agreement; provided, however, that any such assignment shall not relieve such Fund of any of its obligations under this letter (including its obligation to fund its Individual Commitment Cap of the Commitment hereunder), except to the extent performed at Closing by such affiliated investment funds, affiliated separately managed accounts or affiliated investment vehicles. All payments hereunder shall be made in lawful money of the United States, in immediately available funds.

2. Conditions. Each Fund’s obligation to fund its Pro Rata Percentage of the Commitment Amount shall be subject to (i) the execution and delivery of the Merger Agreement by the Parties to the Merger Agreement, (ii) satisfaction or valid waiver of each of the conditions to Parent and Merger Sub’s obligations to effect the Closing set forth in Section 7.1 and Section 7.2 of the Merger Agreement (in each case, other than any conditions that by their nature are to be satisfied at the Closing, but subject to the prior or substantially concurrent satisfaction or valid waiver of such conditions), (iii) the substantially simultaneous consummation of the Closing in accordance with the terms of the Merger Agreement, (iv) the substantially contemporaneous funding of the full amount of the Debt Financing in accordance with the terms of the Debt Commitment Letter and (v) the consummation of the Rollover immediately prior to or substantially concurrent with the consummation of the Closing pursuant to the terms of the Merger Agreement and the Support and Rollover Agreement.

3. Limited Guarantee. Concurrently with the execution and delivery of this Agreement, the Funds have executed and delivered to the Company a limited guarantee pursuant to which the Funds have agreed, on the terms and subject to the conditions therein, to guarantee certain of Parent’s payment obligations under the Merger Agreement (the “Limited Guarantee”). Each Fund acknowledges and agrees that if the conditions described in Section 2 hereof are satisfied, the Company may seek an order of specific performance to enforce each Fund’s obligation to fund its Pro Rata Percentage of the Commitment Amount hereunder, pursuant to (and on the terms and subject to the conditions of) Section 9.9(b)(ii) of the Merger Agreement (the “Specific Performance Rights”). Other than the Specific Performance Rights and the other Retained Claims (as defined in the Limited Guarantee), the Company’s right to receive payment from Parent of the Guaranteed Obligations (as defined in the Limited Guarantee), subject to the Cap (as defined in the Limited Guarantee) and otherwise on the terms and subject to the conditions of the Limited Guarantee, is and shall be the sole and exclusive direct or indirect remedy (whether at law or in equity) available to the Company, its Subsidiaries, any of their respective directors, officers, employees, and Affiliates, and each of the Rollover Stockholders and any other security holder of the Company who has executed and delivered a Support and Rollover Agreement and any of their respective Affiliates (each such Person, a “Company Related Party”) (or available to any Person claiming by, through, or on behalf or for the benefit of any of the Company Related Parties) against the Funds or any other Non-Recourse Party (as defined in the Limited Guarantee) with respect to any claim (whether sounding in contract or tort, under statute or otherwise) arising under or related to the Merger Agreement, the Limited Guarantee, this Agreement or the transactions contemplated hereby or thereby or related negotiations, including without limitation in connection with any breach or alleged breach by Parent or Merger Sub of any obligation under or related to the Merger Agreement, whether or not any such breach or alleged breach is caused by the Funds’ breach of their obligations under this Agreement and any breach or alleged breach by the Funds of any obligation under or related to the Limited Guarantee or this Agreement. Each Fund agrees, solely in the context of Section 9.9(b) of the Merger Agreement, not to oppose the granting of an injunction or specific performance on the basis that (i) the Company has an adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or in equity.

4. Confidentiality. This Agreement shall be treated as confidential and is being provided to Parent solely in connection with the transactions contemplated by the Merger Agreement. This Agreement may not be used, circulated, quoted or otherwise referred to in any document (other than the Limited Guarantee and the Merger Agreement) by Parent, the Company or their respective Affiliates except with the prior written consent of Parent and the Funds in each instance; provided, that no such written consent is required for any disclosure of the existence of this Agreement (i) to the extent required by applicable Law (provided, that to the extent permissible by applicable Law, the disclosing party shall use its commercially reasonable efforts to give the non-disclosing parties prior notice of such disclosure and, upon any such other party’s request, shall use commercially reasonable efforts to obtain confidential treatment for the existence and terms of this letter) or in connection with any litigation related to the Merger Agreement or the transactions contemplated hereby or thereby, (ii) in connection with seeking the approval, consent, or waiver from, or in connection with the filing of any notices or similar responses, in each case with any Governmental Authority as required by the Merger Agreement, or (iii) to representatives of Parent or the Company who reasonably need to know of the existence of this Agreement in connection with the transactions contemplated hereby. Notwithstanding the foregoing, this Agreement may be provided to certain investment funds managed or controlled by Affiliates of Xxxx Capital Private Equity, LP, and the existence of this Agreement may be disclosed by them to (x) their respective Affiliates and representatives who are subject to confidentiality obligations and (y) to the extent required by Law.
