INTRODUCTION
This Transaction Statement on Schedule 13E-3 (the “Transaction Statement”) is being filed with the U.S. Securities and Exchange Commission (the “SEC”) pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), jointly by the following persons (each, a “Filing Person,” and collectively, the “Filing Persons”): (1) Diversey Holdings, Ltd., a Cayman Islands exempted company (“Diversey” or the “Company”) and the issuer of the Ordinary Shares, $0.0001 par value (the “Ordinary Shares”) that is the subject of the Rule 13e-3 transaction; (2) Olympus Water Holdings IV, L.P., a Cayman Islands exempted limited partnership (“Parent”); (3) Diamond Merger Limited, a Cayman Islands exempted company and a wholly owned subsidiary of the Parent (“Merger Sub”); (4) Platinum Equity Capital Partners IV, L.P., a Delaware limited partnership (“Platinum IV”); (5) Platinum Equity Capital Partners V, L.P., a Delaware limited partnership (“Platinum V”); (6) BCPE Diamond Investor, LP, a Delaware limited partnership (the “Bain Shareholder”), the Company’s controlling shareholder and an entity advised by Bain Capital Private Equity, LP; (7) BCPE Diamond GP, LLC, a Delaware limited liability company; (8) Bain Capital Fund XI, LP, a Cayman Islands exempted limited partnership; (9) Bain Capital Partners XI, L.P., a Cayman Islands exempted limited partnership; and (10) Bain Capital Investors, LLC, a Delaware limited liability company.
This Transaction Statement relates to the Agreement and Plan of Merger, dated March 8, 2023 (including all exhibits and documents attached thereto, and as it may be amended from time to time, the (“Merger Agreement”), by and among Parent, acting by its general partner, Olympus Water Holdings Limited, a Cayman Islands exempted company incorporated with limited liability, Merger Sub, and the Company. The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger and becoming a wholly owned subsidiary of Parent (the transaction contemplated by the Merger Agreement, including the Merger, collectively, the “Transactions”).
At the effective time of the Merger (the “Effective Time”), each Ordinary Share issued and outstanding at the Effective Time (other than (1) the Ordinary Shares held by the Company, Parent, Merger Sub or any direct or indirect wholly owned subsidiary of Parent or Merger Sub (each, an “Owned Company Share”), (2) the Ordinary Shares as to which the holder has validly exercised and perfected and not effectively withdrawn or lost their rights to dissent under the applicable provisions of the Companies Act (2023 Revision) of the Cayman Islands (the “CICA”), (3) the Rollover Shares (as defined below) and (4) the Ordinary Shares held by the Bain Shareholder that are not Rollover Shares (as defined below) (the “Bain Shares”)) will automatically be canceled and converted into the right to receive cash in an amount equal to $8.40, without interest thereon and subject to any applicable withholding taxes. At the Effective time, each Owned Company Share will automatically be cancelled and extinguished without any conversion thereof or consideration paid therefor, and the Bain Shares will automatically be cancelled and converted into the right to receive cash in an amount equal to $7.84, without interest thereon and subject to any applicable withholding taxes (the “Bain Consideration”). Upon completion of the Merger, the Ordinary Shares will no longer be publicly traded, and the Company’s shareholders (other than holders of the Rollover Shares, indirectly) will cease to have any ownership interest in the Company. Certain Ordinary Shares (the “Rollover Shares”) will be exchanged by the Bain Shareholder immediately prior to the Effective Time for common and preferred units of Olympus Water Holdings I, L.P. (“Topco”), a Cayman Islands exempted limited partnership and affiliate of Platinum Equity, LLC (“Platinum”) (and, in certain circumstances, preferred interests of a subsidiary of Topco) in accordance with the terms of the Rollover Contribution Agreement (the “Rollover Agreement”), dated as of March 8, 2023 (as may be amended, restated or otherwise modified from time to time), by and among the Bain Shareholder and Topco (such Rollover Shares being valued at an amount equal to the Bain Consideration). The Rollover Shares represent approximately 56.1% of the Ordinary Shares held by the Bain Shareholder immediately prior to the Effective Time (which amount is subject to increase up to approximately 61.5% if Topco elects, prior to the closing of the Merger, to cause the Bain Shareholder to contribute additional Ordinary Shares in exchange for additional preferred units of Topco (or a subsidiary thereof)).
On March 8, 2023, concurrently with the execution of the Merger Agreement, the Bain Shareholder (in its capacity as a shareholder of the Company), entered into the Voting Agreement with the Company and Parent (the “Voting Agreement”), pursuant to which the Bain Shareholder agreed, among other things, to vote the Bain Shares in favor of the adoption of the Merger Agreement.

In connection with entering into the Merger Agreement, on March 8, 2023, the Company, Parent, Merger Sub, Diversey Holdings I (UK) Limited, a private limited company organized in England and Wales (“Holdings UK”), Topco, the Bain Shareholder and BCPE Diamond Cayman Holding Limited, a Cayman Islands exempted company (“BCPE Cayman”) as representative to the shareholders, entered into the Tax Indemnity Agreement (the “Tax Indemnity Agreement”). Pursuant to the Tax Indemnity Agreement, and in connection with the transactions contemplated by the Merger Agreement, Rollover Agreement and TRA Termination Agreement (as defined below), the Bain Shareholder has agreed to indemnify, defend and hold harmless Topco and its subsidiaries and affiliates (including Parent and the surviving Company), and each of their respective officers, directors, partners, members, employees, agents, representatives, successors and permitted assigns against certain taxes and related losses (including interest and penalties) of the Company and its subsidiaries, subject to the terms and conditions contained in the Tax Indemnity Agreement. Additionally, on March 8, 2023, the Company, Holdings UK and BCPE Cayman, entered into the Tax Receivable Termination Agreement (the “TRA Termination Agreement”), pursuant to which, among other things, the parties agreed to terminate the Company’s existing Tax Receivable Agreement, dated as of March 24, 2021, by and among the Company, Holdings UK, BCPE Cayman, as representative to the shareholders, and the other parties thereto (the “Tax Receivable Agreement”), with such termination effective upon the consummation of the Merger. From and after the effective date of the TRA Termination Agreement, no payments will be made to any person in respect of, or pursuant to, the Tax Receivable Agreement.
The board of directors of the Company (the “Board”) formed a special committee of the Board comprised solely of directors of the Company who are not directly or indirectly affiliated with, and who are otherwise independent from, the Bain Shareholder and Platinum and who are not members of the Company’s management (the “Special Committee”) to consider if the Transactions were fair to, and in the best interest of, the Company and the Unaffiliated Shareholders (as defined below), and to review, evaluate and negotiate the terms and conditions thereof and take other actions that the Special Committee deemed appropriate. The Special Committee, as more fully described in the preliminary Proxy Statement, evaluated the Merger in consultation with the Company’s management and its own independent legal and financial advisors and considered various material factors. After careful consideration, and after several months of diligence and additional negotiations, the Special Committee, pursuant to resolutions adopted at a meeting of the Special Committee held on March 7, 2023, unanimously (1) determined that the transactions contemplated by the Merger Agreement and the Plan of Merger required to be filed with the Cayman Islands Registrar of Companies, attached as Exhibit A to the Merger Agreement (as it may be amended from time to time, the “Plan of Merger”), including the Merger Agreement, the TRA Termination Agreement, the Voting Agreement and the Limited Guarantee, dated as of March 8, 2023 (as amended, modified or supplemented (including by waiver or consent) from time to time), executed by Platinum IV and Platinum V (and the Company) and delivered to the Company (the “Limited Guarantee”), are fair to, and in the best interests of, the Unaffiliated Shareholders (as defined below); (2) recommended that the Board approve, adopt and declare advisable the Merger Agreement and cause the Company to consummate the Merger upon the terms and subject to the conditions set forth therein; (3) recommended that the Board approve the execution, delivery and performance by the Company of its covenants and other obligations under the Merger Agreement, the TRA Termination Agreement, the Voting Agreement and the Limited Guarantee, and the consummation by the Company of the contemplated transactions thereby, upon the terms and conditions set forth therein, (4) recommended that the Board direct that the Merger Agreement and the Plan of Merger be submitted to the Company’s shareholders for approval and (5) recommended that the Board resolve to recommend that the Company’s shareholders authorize the Plan of Merger in accordance with the Company’s organizational documents and the CICA. “Unaffiliated Shareholders” means the Company’s unaffiliated security holders as defined under Rule 13e-3 of the Exchange Act.
The Board, based in part on the unanimous recommendation of the Special Committee, unanimously (1) determined that it is in the best interests of the Company, and declared it advisable, to enter into the Merger Agreement and consummate the Merger upon the terms and subject to the conditions set forth therein; (2) approved the execution and delivery of the Merger Agreement by the Company, the performance by the Company of its covenants and other obligations thereunder, and the consummation of the Merger upon the terms and conditions set forth therein; (3) directed that the Merger Agreement and the Plan of
 
3

 
Merger be submitted to the Company’s shareholders for approval; and (4) resolved to recommend that the Company’s shareholders authorize the Plan of Merger in accordance with the Company’s organizational documents and the CICA.
At an extraordinary general meeting of the shareholders of the Company (the “Special Meeting”), the Company’s shareholders will be asked to consider and vote upon (1) a proposal by special resolution to authorize the Merger Agreement, the Plan of Merger and the Transactions (the “Merger Proposal”); and (2) an advisory and non-binding proposal by ordinary resolution on specified compensation that may become payable to the Company’s named executive officers in connection with the Merger (the “Named Executive Officer Merger-Related Compensation Proposal”).
The Merger cannot be completed unless shareholders holding at least two-thirds of the votes cast by the holders of the Ordinary Shares present and voting in person or by proxy and entitled to vote affirmatively vote in favor of the Merger Proposal. The approval of the advisory and non-binding Named Executive Officer Merger-Related Compensation Proposal requires the affirmative vote of at least a simple majority of the votes cast by the holders of Ordinary Shares present and voting in person or by proxy and entitled to vote at the Special Meeting. The approval of the Named Executive Officer Merger-Related Compensation Proposal is not a condition to completion of the Merger.
Concurrently with the filing of this Transaction Statement, the Company is filing a proxy statement (the “Proxy Statement”) under Regulation 14A of the Exchange Act with the SEC, pursuant to which the Company is soliciting proxies from the Company’s shareholders in connection with the Merger. The Proxy Statement is attached hereto as Exhibit (a)(1). A copy of the Merger Agreement is attached to the Proxy Statement as Annex A. As of the date hereof, the Proxy Statement is in preliminary form, and is subject to completion or amendment.

Preliminary Draft Subject to Review and Significant Revision Company Management Forecast: Background 30 Background Information Management prepared the Company Management Forecast in a context where the Company’s post COVID financial performance has been negatively impacted by pockets of volumetric demand deterioration, broad cost inflation, dramatic raw material cost escalations, on-going logistics supply chain inefficiencies/constraints and some Diamond-specific operational challenges associated with some footprint rationalization. Translational FX also was a major impact for the business in this time period 2022 Gross Profit declined by 16% from $1.3bn in 2022 Budget as approved in December 2021 to $1.0bn as per the Company Management Forecast 2022 EBITDA declined by 26% from $450mm in 2022 Budget as approved in December 2021 to $332mm as per the Company Management Forecast Due to the Company’s focus on passing through rapidly escalating costs via price increases and on managing supply chain transformations, certain originally intended growth initiatives have not been executed (albeit the key growth drivers have seen growth, but not to the same extend as expected) Considerations for 2023 and beyond include: COVID remains a factor for China in H1 2023 Inflation and raw material issues expected by Company management to progressively recede Potential negative customer churn impacts may develop as customers have more time to assess accepted 2022 pricing increases / may be under contract Company Management Forecast includes the potential impact of a recession, which is assumed to impact globally Weakening of USD (kept constant from 2024 onward) Company management indicates that a certain number of key actions will be taken to support Diamond’s mid-term and long-term strategy: Completion of the North-American Supply Chain initiative (“Megalodon Project”) Optimising tools developed recently around commercial excellence, CRM, archetypes and operational efficiency / sustainability for customers Pursuing new attractive capex investments From an EBITDA development perspective, the Company Management Forecast contemplates that the Company EBITDA will return to the level as forecasted in its 2022 budget only by 2025E We have also been provided with a previous business plan prepared in Q3 2022 (“3YP (as of 22-Sep)”) F Source: Company Management Forecast, Company Management A B C D E

This was mainly driven by flat performance in Europe which is the most significant part of the Institutional business On a revenue basis, pricing effect was the major contributor to increased revenue from 2019A to 2022LE (+$315mm) vs Volume impact which was (+$104mm) Forecast Performance & Drivers (2023E – 2027E) Revenue On a group level, revenue is forecasted to grow to $3,794mm by 2027E (+6.5% CAGR 22-27E), incl. contribution of $217mm from acquisitions In 2023, the vast majority of this growth is forecast to be derived from price increases, some of which will flow through from 2022 price increases, and some via new 2023 increases (+12.9% increase in 2023E forecast representing ~$382mm). Post 2023, price increases are set to normalise at a level inline with inflation (~3%) Volume drivers assumptions on a long-term basis are derived from Real GDP growth (+2.6%), Growth Initiatives (predominantly Institutional related) (+2.5%) and Customer Churn (-1.1%) By 2027 the key contributors to growth and therefore the key assumptions from a revenue perspective are price (which represents $110mm), Real GDP volume growth (which represents +$100m) and Growth Initiatives (+$95mm) Post 2023, the Institutional business is forecast to benefit long-term from ~4.5% in volume growth annually vs 2.5% with price vs the F&B business which is forecast to grow ~2-3% on a volume basis annually and ~3% from pricing annually Source: Company Management Forecast, Company Management (1) LE = Latest Estimate A B C D E F

M&A) by $90m (+12%) to $818mm, mainly driven by personnel / compensation costs From 2024E onwards, SG&A are forecasted to grow at 3.8% annually until 2027E EBITDA On a group level and incl.

Preliminary Draft Subject to Review and Significant Revision Key Upsides Key Risks Summary of Key Upsides / Risks to the Business Plan 53 In a deflationary environment, lower raw material costs could translate into higher margins Benefits of recent lower inflation (not recognized until 2H 2023) Foreign exchange prices trending favorably imply better margins Potential to capture Ecolab market share for Tier II customers outside of Ecolab focus in specific geographic areas (North America) Growth initiatives could be more realistic in a lower inflation environment Resolution of war in Ukraine would improve supply chain issues and thus improve margins Higher margins could translate into lower leverage, providing available capital for growth initiatives Large cost projects (Megalodon Project) are mostly complete Challenges to Diamond’s ability to grow volumes (prior focus more on price improvements) Lower ability to pass future price increases to customers due to risk of customer/volume loss Continued inflationary environment could increase raw material (caustic soda) prices Benefits of recent lower inflation will not be recognized until 2H 2023, implying 1H low margins Seasonality heading into 1H 2023 will limit cash flows Potential for further cost overruns (Megalodon Project, most but not 100% complete) Limited ability to deleverage near term due to seasonality and working capital Continuation of war in Ukraine on supply chain issues could negatively affect margins Availability and actionability of M&A targets given high leverage and poor stock price performance Management and employee retention Source: Company Management Forecast, Company Filings

(Diversey) has underperformed our prior expectations, with significant inflation in direct material costs weighing on EBITDA margins over the past few quarters The company has instituted pricing actions and energy surcharges to offset these pressures, however, we now anticipate credit metrics will be modestly weaker in 2022 versus our previous forecast Demand in the company's base institutional segment has also rebounded marginally slower than expected following pandemic-related declines, particularly in European and emerging markets (about 70% of revenue), where re-opening proceeded slower than in North America As a result, we affirmed our 'B' issuer-credit rating on Diversey, and revised our outlook to stable from positive

They are rejecting an equity component to the public Seller Note: Unwilling to offer as a form of consideration; perhaps possible but creates unwanted complexity. They are rejecting a seller note component to the public Transaction attractiveness was / is predicated on Diamond’s status as a Cayman Islands incorporated company, where Baryte’s support can ensure transaction certainty Countered at $7.75 / share Pearl will not take responsibility for splitting value differentially, as they feel that is something for the Special Committee to address $7.75 / share should not be considered a “best and final” as the Pearl team is still conducting diligence Pearl noted that as part of their negotiation with Baryte, Baryte had communicated that it would waive the TRA and that the TRA value would then accrue to current shareholders via Pearl’s bid. Just this week, Pearl received a memo on Feb. 7 that details some issues pertaining to challenges and limitations to the Dutch tax assets, which could reduce Pearl’s valuation of Diamond; Pearl did not have a specific number to cite as to how much TRA value (Pearl mentioned an off-the-cuff range of $30-150mm but is subject to further diligence) they had embedded in the original $7.50 / share bid, nor could they comment on how much it might adjust their new $7.75 / share bid Feb 2nd Messages to Pearl Feb 6th Pearl Response

Preliminary Draft Subject to Review and Significant Revision 15/11/2021 ▪ “We believe CSPR's lower multiple is due to the co. remaining unprofitable (while all others generate profits). Plus, CSPR's performance has been less consistent than the others in the sector over the past year. As such, the purchase price of 0.4x '22E revs appears fair, in our view.” 03/11/2022 ▪ “We think that TIG’s financial profile has come less differentiated in the current hard market, with most commercial peers enjoying comparable or better growth and margins. Also, we believe that TIG is exposed to the risk of downward EPS revisions” 11/01/2023 ▪ “$19/share is higher than where DCT has traded since late 2021, and ~6x FY24E EV/Sales makes sense with a turn premium to close competitor/valuation comp GWRE. The go-shop period has been a focus for several investors, and we think likelihood of a competing bid is low” 23/01/2023 ▪ “We believe SUMO is an inferior asset to others in the observability/security space and should reflect a discounted multiple (in the 3-5x range). we point to the significant difference in scale versus Splunk, its closest competitor” 08/11/2021 ▪ “MCFEs fundamentals are set to soften as comps get tougher and competitive pressures increase. NortonLifeLock's proposed merger with Avast is set to close in mid CY22. This will create a challenger that can outmuscle MCFE in competitive situations with OEM partners, removing a funnel for customer acquisition. Furthermore, McAfee might have to ramp marketing spend to match this larger competitor, limiting margin accretion” 12/10/2022 ▪ “While KnowBe4 has been executing quite well and the firm had yet to note any signs macro slowdown, we likewise know this remains a competitive space, and the reality is that bets on things like SecurityCoach and PasswordIQ have yet to be proven out – that’s to say, we can’t fault the team for selling here” 02/09/2022 ▪ “We believe F45 Training's differentiated technology-enabled platform, strong global presence, and rapidly growing studio footprint are likely to further solidify the company’s competitive positioning in the global fitness industry. Additionally, we believe there is meaningful opportunity for the company to gain market share, as it continues to grow its global studio footprint.” 14/12/2022 ▪ “This price target represents ~50x our CY23 adj. EBITDA and ~2.6x our CY23 sales estimates. Clearly, this is well above peers', entirely reflecting the take private transaction offer. That's why we're Equal Weight.” 11/10/2022 ▪ “This is also slightly above security peer average currently trading at 7.2 EV/CY23 sales and 0.34X growth adjusted. Given recent macro headwinds and negative near-term profitability, we think this is a favorable outcome for the company.” 11/10/2022 ▪ “At the acquisition price of $7.50, UserTesting shares are valued at 4.9 times our 2023 revenue estimate, in line with the SaaS peer group median of 4.8 times. In our view, a materially higher bid is unlikely given recent volatility in software markets and the hefty premium that Thoma Bravo paid. Thus, we are downgrading our rating on UserTesting to Market Perform. Primary risks include competition from larger software vendors in adjacent categories, contributor network churn as the economy normalizes, and a return to traditional lab testing as COVID-19 abates.” Recent IPO Take-Privates (4/6) 5 Source: Broker Reports

Preliminary Draft Subject to Review and Significant Revision Transaction Background (1/3) 4 Context The Target Company: Diamond (“Diamond” or the “Company”) has been listed on Nasdaq since its IPO on March 25, 2021 Shareholders in the Company consist of affiliated shareholders (“Baryte”), representing ~73% of the Company’s issued and outstanding shares, and unaffiliated shareholders / public float, representing ~27% Evercore Role: In the context of the proposed acquisition by Pearl and its affiliated company Sapphire (together “Pearl”), of all the issued and outstanding shares of the Company (the “Proposed Transaction”), a Special Committee of the Board of Directors of Diamond (the “Special Committee”) was formed on January 17, 2023, with the authority to, among other things, negotiate with respect to the Pearl proposal and determine whether a transaction would be in the best interests of the Company and its unaffiliated shareholders (including the authority to reject a transaction); Evercore L.L.C. (“Evercore”) has been engaged as financial advisor to the Special Committee This presentation should be read in conjunction with Evercore’s Discussion Materials Prepared for the Special Committee, dated February 1, 2023 (with market data as per January 27, 2023 “EVR 1-Feb Materials”) Background to Offers 1 st Offer: On August 3, 2022, Pearl submitted a letter of intent for a take private acquisition of Diamond, whereby each outstanding share of Diamond would be acquired for $11.00 in cash This offer represented a 47% premium to Diamond’s closing share price on August 2, 2022, and a 54% premium to the Company’s VWAP for the 30-day trading period ended August 2, 2022 and an implied TEV / NTM EBITDA multiple of 14.4x The 1st Offer assumed that Baryte would roll-over a portion of its equity position in the combined entity Initial Diligence Work Autumn 2022: Pearl conducted certain due diligence activities on Diamond from September 2022, which included, among others things, a management presentation, Q&A sessions, access to a virtual dataroom, access to Diamond’s 3-year business plan, certain site visits and preparation by a third party of a report on potential synergies resulting from the combination of Diamond and Sapphire 2 nd Offer: On January 11, 2023, Pearl submitted a subsequent letter of intent for a take private acquisition of Diamond, whereby each outstanding share of Diamond would be acquired for $7.50 in cash (please refer to Pearl’s Source and Uses in Section III of this presentation for a breakdown of the consideration mix between Diamond shareholders) This offer represented a 53% premium to Diamond’s closing share price as of January 10, 2023, and a 60% premium to the Company’s VWAP for the 30-day trading period ended January 11, 2023 and an implied TEV / 2023E EBITDA of 11.6x. The 2nd Offer was 32% lower than the 1st Offer Source: Letter of Intent, dated as of August 3, 2022, delivered by Pearl to Diamond; Letter of Intent, dated as of January 11, 2023, delivered by Pearl to Diamond

Preliminary Draft Subject to Review and Significant Revision Transaction Background (2/3) 5 Background to Offers (Cont’d) On February 2, 2023, at the direction of the Special Committee, Evercore delivered the message to Pearl that the Special Committee was of the view that: Diamond’s unaffiliated shareholders should receive at least $10.20 per share in cash This transaction should be subject to an affirmative Majority of the Minority Condition The form of consideration mix being offered to Baryte should also be offered as an option to the unaffiliated shareholders 3 rd Offer: On February 7, 2023, Pearl verbally made an improved offer at $7.75 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 28% premium to Diamond’s closing share price on February 6, 2023, and a 48% premium to the Company’s VWAP for the 30-day trading period ended February 6, 2023 and an implied TEV / 2023E EBITDA multiple of 11.8x The offer followed a two day Commercial diligence and Synergies diligence session between both the Pearl and Diamond respective leadership teams, held in New York, that was characterized as “constructive” The $7.75 per share price offered by Pearl reflected that there would be no Tax Related Assets (“TRA”) payout made to Baryte in connection with the transaction, with an expectation offered by Baryte that the TRA was worth ~$30-150mm; – Pearl affirmed that they did not know how much of the TRA was Dutch or how much was being reflected in the 3rd Offer bid price but commented that the bid value was not reflecting a $150mm valuation of the TRA Pearl rejected the requests to (a) offer to the public an option to take the same forms of consideration that Baryte would be receiving as part of the contraction given Pearl had no interest in having Sapphire be a publicly listed entity going forward, nor for the complexity involved in such a transaction and (b) have the transaction be subject to an affirmative Majority of the Minority Condition as that was not a requirement for a Cayman domiciled company and it reduced transaction certainty for Pearl, to which Pearl ascribes meaningful importance Pearl was more comfortable with some form of Go-Shop provision Pearl also stated that they were not prepared to involve themselves in splitting the equity value of the offer between Baryte and the unaffiliated shareholders to the extent that differential considerations between Diamond shareholders became a topic On February 12, 2023, Baryte presented its perspectives on its investment thesis in Diamond to ‘inflect growth’ and Baryte’s views on the operational and macro challenges that could limit Diamond’s ability to deliver value to shareholders 4 th Offer: On February 14, 2023, Pearl verbally made an improved offer at $7.90 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 36% premium to Diamond’s closing share price on February 13, 2023, and a 42% premium to the Company’s VWAP for the 30-day trading period ended February 13, 2023 and an implied TEV / 2023E EBITDA multiple of 12.0x

Preliminary Draft Subject to Review and Significant Revision Background to Offers (Cont’d) On February 16, 2023, at the direction of the Special Committee, Evercore delivered the message to Pearl that the Special Committee was of the view that Diamond’s unaffiliated shareholders should receive at least $9.00 per share in cash, or, were Pearl to agree to make the transaction subject to the approval of a majority of the unaffiliated shareholders (“Majority of the Minority Condition”), a price to Diamond’s unaffiliated shareholders of at least $8.00 per share in cash 5 th Offer: On February 28, 2023, Pearl made verbally an improved offer at $7.95 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 35% premium to Diamond’s closing share price on February 28, 2023, and a 37% premium to the Company’s VWAP for the 30-day trading period ended February 28, 2023 and an implied TEV / 2023E EBITDA multiple of 12.0x Pearl stated that they were constrained from going higher due to (a) their sceptical perspective on some of the adjustments embedded in 2022’s ~$330mm Adjusted EBITDA (vs. the ~$100mm of Reported EBITDA), (b) lower valuation of the public’s share of the Dutch Tax Assets, for which there will not be an indemnification that mirrors that provided to Pearl by Baryte for Baryte’s share of the tax asset value and (c) Medline litigation which Pearl expects to bring material legal defence costs at a minimum Pearl continued to be unwilling to be a party to any differential cash equity value allocation amongst Baryte and Diamond’s unaffiliated shareholders that would be necessary to achieve the Special Committee’s $9.00 per share value for unaffiliated shareholders Pearl will not support a transaction that is predicated on a Majority of the Minority Condition Pearl requires that the Special Committee’s Fiduciary Out be limited to 30 days post-signing Pearl shared their draft debt commitment letter, base fee letter and agency fee letter with Wachtell and with Evercore Pearl refreshed the Sources & Uses to reflect the $.05/share increase in equity price As informed by Pearl, the LP fundraising process is constructively advancing, but likely not reaching its conclusion prior to the envisaged signing date. As a result, it is understood that Pearl would plan to backstop the LP fundraising between signing and close via contingent commitments from Pearl’s Fund IV and Fund V; Pearl did not mention that Baryte would need to participate in the backstop Pearl noted that signing and announcing a transaction in advance of Diamond’s earnings would avoid a situation where Diamond’s share price drops post its earnings release and shareholders who sell in response then miss the sale announcement associated share price uplift {it was not discussed as to whether, in the event that a transaction was in negotiations but not yet agreed, there might be some form of announcement to alert shareholders to the possibility of a transaction} Transaction Background (3/3) 6

Preliminary Draft Subject to Review and Significant Revision Transaction Background (2/4) 3 Background to Offers (Cont’d) On February 2, 2023, at the direction of the Special Committee, Evercore delivered the message to Pearl that the Special Committee was of the view that: Diamond’s unaffiliated shareholders should receive at least $10.20 per share in cash This transaction should be subject to an affirmative Majority of the Minority Condition The form of consideration mix being offered to Baryte should also be offered as an option to the unaffiliated shareholders Pearl’s 3rd Offer: On February 7, 2023, Pearl verbally made an improved offer at $7.75 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 28% premium to Diamond’s closing share price on February 6, 2023, and a 48% premium to the Company’s VWAP for the 30-day trading period ended February 6, 2023 and an implied TEV / 2023E EBITDA multiple of 11.8x The offer followed a two day Commercial diligence and Synergies diligence session between both the Pearl and Diamond respective leadership teams, held in New York, that was characterized as “constructive” The $7.75 per share price offered by Pearl reflected that there would be no Tax Related Assets (“TRA”) payout made to Baryte in connection with the transaction, with an expectation offered by Baryte that the TRA was worth ~$30-150mm; – Pearl affirmed that they did not know how much of the TRA was Dutch or how much was being reflected in the 3rd Offer bid price but commented that the bid value was not reflecting a $150mm valuation of the TRA Pearl rejected the requests to (a) offer to the public an option to take the same forms of consideration that Baryte would be receiving as part of the contraction given Pearl had no interest in having Sapphire be a publicly listed entity going forward, nor for the complexity involved in such a transaction and (b) have the transaction be subject to an affirmative Majority of the Minority Condition as that was not a requirement for a Cayman domiciled company and it reduced transaction certainty for Pearl, to which Pearl ascribes meaningful importance Pearl was more comfortable with some form of Go-Shop provision Pearl also stated that they were not prepared to involve themselves in splitting the equity value of the offer between Baryte and the unaffiliated shareholders to the extent that differential considerations between Diamond shareholders became a topic On February 12, 2023, Baryte presented its perspectives on its investment thesis in Diamond to ‘inflect growth’ and Baryte’s views on the operational and macro challenges that could limit Diamond’s ability to deliver value to shareholders Pearl’s 4th Offer: On February 14, 2023, Pearl verbally made an improved offer at $7.90 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 36% premium to Diamond’s closing share price on February 13, 2023, and a 42% premium to the Company’s VWAP for the 30-day trading period ended February 13, 2023 and an implied TEV / 2023E EBITDA multiple of 12.0x

Preliminary Draft Subject to Review and Significant Revision Background to Offers (Cont’d) On February 16, 2023, at the direction of the Special Committee, Evercore delivered the message to Pearl that the Special Committee was of the view that Diamond’s unaffiliated shareholders should receive at least $9.00 per share in cash, or, were Pearl to agree to make the transaction subject to the approval of a majority of the unaffiliated shareholders (“Majority of the Minority Condition”), a price to Diamond’s unaffiliated shareholders of at least $8.00 per share in cash Pearl’s 5th Offer: On February 28, 2023, Pearl made verbally an improved offer at $7.95 per share in cash for all shareholders (and also shared corresponding Sources & Uses) This offer represented a 35% premium to Diamond’s closing share price on February 28, 2023, and a 37% premium to the Company’s VWAP for the 30-day trading period ended February 28, 2023 and an implied TEV / 2023E EBITDA multiple of 12.0x Pearl stated that they were constrained from going higher due to (a) their sceptical perspective on some of the adjustments embedded in 2022’s ~$330mm Adjusted EBITDA (vs. the ~$100mm of Reported EBITDA), (b) lower valuation of the public’s share of the Dutch Tax Assets, for which there will not be an indemnification that mirrors that provided to Pearl by Baryte for Baryte’s share of the tax asset value and (c) Medline litigation which Pearl expects to bring material legal defence costs at a minimum Pearl continued to be unwilling to be a party to any differential cash equity value allocation amongst Baryte and Diamond’s unaffiliated shareholders that would be necessary to achieve the Special Committee’s $9.00 per share value for unaffiliated shareholders Pearl will not support a transaction that is predicated on a Majority of the Minority Condition Pearl requires that the Special Committee’s Fiduciary Out be limited to 30 days post-signing Pearl shared their draft debt commitment letter, base fee letter and agency fee letter with Wachtell and with Evercore Pearl refreshed the Sources & Uses to reflect the $.05/share increase in equity price As informed by Pearl, the LP fundraising process is constructively advancing, but likely not reaching its conclusion prior to the envisaged signing date. As a result, it is understood that Pearl would plan to backstop the LP fundraising between signing and close via contingent commitments from Pearl’s Fund IV and Fund V; Pearl did not mention that Baryte would need to participate in the backstop Pearl noted that signing and announcing a transaction in advance of Diamond’s earnings would avoid a situation where Diamond’s share price drops post its earnings release and shareholders who sell in response then miss the sale announcement associated share price uplift {it was not discussed as to whether, in the event that a transaction was in negotiations but not yet agreed, there might be some form of announcement to alert shareholders to the possibility of a transaction} On March 2, 2023, at the direction of the Special Committee, Evercore delivered the message to Pearl that the Special Committee was of the view that Diamond’s unaffiliated shareholders should receive at least $8.90 per share in cash and to achieve this outcome, Pearl should engage with Baryte to look to find ways to modify the deal between those two future partners to accommodate the delivery of the $8.90 per share to Diamond’s unaffiliated shareholders Transaction Background (3/4) 4

Key Upsides Key Risks Summary of Key Upsides / Risks to the Business Plan In a deflationary environment, lower raw material costs could translate into higher margins Benefits of recent lower inflation (not recognized until 2H 2023) Foreign exchange prices trending favorably imply better margins Potential to capture greater market share for customers in specific geographic areas such as North America Growth initiatives could be more realistic in a lower inflation environment Resolution of war in Ukraine would improve supply chain issues and thus improve margins Higher margins could translate into lower leverage, providing available capital for growth initiatives Large cost projects (Megalodon Project) are mostly complete Challenges to Diamond’s ability to grow volumes (prior focus more on price improvements) Lower ability to pass future price increases to customers due to risk of customer/volume loss Continued inflationary environment could increase raw material (caustic soda) prices Benefits of recent lower inflation will not be recognized until 2H 2023, implying 1H low margins Seasonality heading into 1H 2023 will limit cash flows Potential for further cost overruns (Megalodon Project, most but not 100% complete) Limited ability to deleverage near term due to seasonality and working capital Continuation of war in Ukraine on supply chain issues could negatively affect margins Availability and actionability of M&A targets given high leverage and poor stock price performance Management and employee retention Source: Company Management Forecast, Company Filings 45

Ladies and Gentlemen:

 

Reference is made to the Agreement and Plan of Merger, dated as of the date hereof, by and among OLYMPUS WATER HOLDINGS IV, L.P., a Cayman Islands exempted limited partnership, acting by its general partner, General Partner (“Parent”), DIAMOND MERGER LIMITED, a Cayman Islands exempted company and a wholly-owned Subsidiary of Parent (“Merger Sub”), and DIVERSEY HOLDINGS, LTD., a Cayman Islands exempted company (the “Company”) (as the same may be amended from time to time, the “Merger Agreement”), pursuant to which, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Company, with the Company as the surviving entity and a wholly-owned Subsidiary of Parent. Capitalized terms used but not defined herein have the meanings ascribed to them in the Merger Agreement.

 

1.            Commitment. Each of Platinum Equity Capital Partners IV, L.P., a Delaware limited partnership, and Platinum Equity Capital Partners V, L.P., a Delaware limited partnership (each a “Sponsor” and, together, the “Sponsors”), severally and not jointly, hereby commits to contribute to Parent or its Affiliates, directly or indirectly through one or more intermediaries, at the Closing and on the terms and subject to the conditions contained herein and in the Merger Agreement, in cash in immediately available funds, their Pro Rata Portion (as defined below) of an aggregate amount in U.S. dollars that is equal to $950,000,000 (the amount of such Sponsor’s Pro Rata Portion being such Sponsor’s “Commitment”), in exchange, directly or indirectly, for equity securities of Parent or its Affiliates, solely for the purpose of funding, and to the extent necessary to fund, together with the net proceeds of the Debt Financing, all of the amounts required to be paid by Parent in connection with the consummation of the Closing pursuant to Sections 2.8(n) (Payment Procedures), 2.9(b) (Payment Fund) and 6.16 (Company Payoff Indebtedness) of the Merger Agreement, together with related fees, costs and expenses required to be paid by Parent, Merger Sub or the Surviving Company in connection with the transactions contemplated by the Merger Agreement (together, the “Closing Payments”). Furthermore (a) in the event a Sponsor assigns a portion of its Commitment to one or more Permitted Assignees in accordance with Section 7 (No Assignment) hereof, the amount required to be funded by the Sponsor will be reduced on a dollar-for-dollar basis by the portion of such Sponsor’s Commitment pursuant to this letter actually funded by such Permitted Assignee in cash to Parent at the Closing; and (b) the Commitment may be reduced by Parent in an amount specified by Parent solely to the extent that, after giving effect to such reduction, and by reason of Parent having obtained funds from other sources, Parent is able to fund all of the Closing Payments required by it pursuant to, and consummate the transactions contemplated by, the Merger Agreement in accordance with the terms thereof. The term “Pro Rata Portion” means (A) with respect to Platinum Equity Capital Partners IV, L.P., 31.58% and (B) with respect to Platinum Equity Capital Partners V, L.P., 68.42%.

 

 

 

 

2.            Representations and Warranties. Each Sponsor represents and warrants as to itself, and not as to the other Sponsor, that (a) this letter has been duly and validly executed and delivered by such Sponsor and upon execution and delivery of the Merger Agreement, this letter will constitute a legal, valid and binding obligation of such Sponsor enforceable against such Sponsor in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting creditors’ rights generally, and (ii) general equitable principles (whether considered in a proceeding in equity or at law); (b) such Sponsor is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has the requisite power and authority to enter into this letter and to perform its obligations hereunder; (c) the execution, delivery and performance of this letter has been duly and validly authorized by all necessary action and does not contravene, conflict with or result in any violation of any provision of such Sponsor’s certificate of formation, limited partnership agreement or other organizational or governing documents or any Law binding on such Person or its assets; (d) such Sponsor has sufficient cash or unfunded capital commitments to cause its Commitment to be funded to Parent pursuant to and in accordance with this letter; and (e) all funds necessary for such Sponsor to perform all of its obligations under this letter shall be available (in the form of cash or unfunded capital commitments) to it for so long as this letter shall remain in effect, and no additional internal approval is needed to fulfill such Sponsor’s obligations hereunder.

 

3.            Conditions. The obligation of each Sponsor to fund its Commitment (a) is subject to (i) the satisfaction or waiver by Parent and Merger Sub of all conditions precedent set forth in Sections 7.1 (Conditions to Each Party’s Obligations to Effect the Merger) and 7.2 (Conditions to the Obligations of Parent and Merger Sub) of the Merger Agreement to Parent’s and Merger Sub’s obligations to consummate the Closing (other than those conditions that are by their terms to be satisfied at the Closing, but subject to such conditions being capable of being satisfied); and (ii) the prior or substantially simultaneous closing and funding of the Debt Financing, or the Debt Financing Sources having confirmed in writing that the Debt Financing (including for the avoidance of doubt, any Alternative Financing) is capable of being funded in full at the Closing if the Commitment is funded at the Closing; and (b) is subject to, and will occur contemporaneous with, the Closing.

 

4.            Term; Termination. Each Sponsor’s Commitment shall become effective on the date and time at which the Merger Agreement has been duly executed by all parties thereto. Each Sponsor’s obligation to fund its Commitment will terminate automatically and immediately upon the earliest to occur of (a) the funding of such Commitment and consummation of the Closing in accordance with the terms of the Merger Agreement, (b) the termination of the Merger Agreement in accordance with its terms, (c) the Company or any of its controlled Affiliates or agents duly authorized to act on the Company’s or its controlled Affiliates’ behalf or Bain or any of its controlled Affiliates or agents duly authorized to act on Bain’s or its controlled Affiliates’ behalf asserting, filing or otherwise commencing, directly or indirectly, any lawsuit or other legal proceeding asserting a claim under, or action against, any Sponsor Related Party (as defined below) in connection with this letter, the Guarantee, the Merger Agreement, the Debt Commitment Letters or any transaction contemplated hereby or thereby or otherwise relating hereto or thereto, other than any Permitted Claim (as defined in, and to the extent permitted under, Section 2 (Changes in Obligations; Certain Waivers) of the Guarantee), in each case, subject to all of the terms, conditions and limitations herein and therein, or (d) the occurrence of any event which, by the terms of the Guarantee, is an event which terminates the Obligations, as defined in the Guarantee. Upon termination of this letter, the Sponsors shall have no further obligations or liabilities hereunder.

5.             No Third Party Beneficiaries. This letter shall be binding solely on, and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns, and nothing set forth in this letter shall be construed to confer upon or give to any Person other than the parties hereto and their respective successors and permitted assigns any benefits, rights or remedies under or by reason of, or any rights to enforce or cause Parent or Merger Sub to enforce, the Commitment or any provisions of this letter; provided that, subject to the terms and conditions of the Merger Agreement, including Section 9.8 (Remedies) thereof, to the extent the Company is entitled to specific performance of the obligations of Parent under the Merger Agreement in the limited circumstances set forth in Section 9.8 (Remedies) thereof, the Company shall be a third party beneficiary of the enforcement rights granted to Parent under this letter solely for the purpose of seeking specific performance of Parent’s right to cause the Commitment to be funded hereunder in accordance with Section 1 (Commitment) hereof (solely to the extent that Parent can enforce the Commitment pursuant to the terms hereof) and for no other purpose (including any claim for monetary damages); provided, further that the Sponsor Related Parties shall be express third party beneficiaries of the provisions set forth herein that are for the benefit of the Sponsor Related Parties, each of which shall survive an expiration or termination of this letter. For the avoidance of doubt, the Company’s remedies in this letter shall be solely with respect to specific performance and the Company shall not have any right to seek or obtain monetary damages pursuant to this letter.

 

6.              Limited Recourse; Enforcement.

 

(a) Notwithstanding anything that may be expressed or implied in this letter, or any document or instrument delivered in connection herewith, Parent, by its acceptance of the benefits of the Commitment, agrees and acknowledges that no Person other than the Sponsors (and any Permitted Assignees) shall have any obligations hereunder and that, notwithstanding that any Sponsor or its Permitted Assignee may be a partnership or limited liability company, no recourse hereunder or under any documents or instruments delivered in connection herewith or in respect of any oral representations made or alleged to have been made in connection herewith or therewith shall be had against any former, current or future director, officer, employee, direct or indirect equityholder, controlling person, general or limited partner, manager, member, stockholder, Affiliate, successor or assign of any Sponsor or any former, current or future director, officer, employee, direct or indirect equityholder, controlling person, general or limited partner, manager, member, stockholder, Affiliate, successor or assign of any of the foregoing (in each case other than the Sponsors, Parent, Merger Sub or any assignee permitted in accordance with the Merger Agreement, each, a “Sponsor Related Party” and collectively, the “Sponsor Related Parties”), whether by or through attempted piercing of the corporate (or limited liability company or limited partnership) veil, by or through a claim by or on behalf of a Sponsor against any Sponsor Related Party, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or Law, or otherwise. It is expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any Sponsor Related Party for any obligations of a Sponsor or any of its respective successors or permitted assigns under this letter or any documents or instruments delivered in connection herewith or in respect of any oral representations made or alleged to have been made in connection herewith or therewith or for any claim (whether at law or equity or in tort, contract or otherwise) based on, in respect of, or by reason of such obligations or their creation.

(b) Subject to the Company’s rights pursuant to Section 5 (No Third Party Beneficiaries) hereof, this letter may only be enforced by Parent against a Sponsor at the direction of such Sponsor in its sole discretion, and Parent shall have no right to enforce this letter against a Sponsor unless directed to do so by such Sponsor in its sole discretion. Parent’s creditors shall have no right to enforce this letter or to cause Parent to enforce this letter.

 

(c) Concurrently with the execution and delivery of this letter and the Merger Agreement, the Sponsors are executing and delivering in favor of the Company a Guarantee related to certain of Parent’s and Merger Sub’s obligations under the Merger Agreement. The Company’s remedies against the Sponsors under the Guarantee shall, and are intended to, be the sole and exclusive direct or indirect remedies available to the Company and the Company Related Parties against the Sponsors and Sponsor Related Parties in respect of any liabilities or obligations (including consequential, indirect or punitive damages, and whether at law, in equity, in contract, in tort or otherwise) arising under, or in connection with, the Merger Agreement or the failure of the Closing to be consummated or otherwise in connection with the transactions contemplated hereby and thereby or in respect of any oral representations made or alleged to have been made in connection herewith or therewith, including in the event Parent or Merger Sub breaches its obligations under the Merger Agreement, whether or not Parent or Merger Sub’s breach is caused by the breach of a Sponsor of its obligations under this letter, except for (i) the Company’s right to seek specific performance of the obligations of Parent in the limited circumstances under Section 9.8 (Remedies) of the Merger Agreement and (ii) the rights of the Company set forth in (A) Section 5 (No Third Party Beneficiaries), (B) Section 7 (No Assignment), (C) the second sentence of Section 12 (Confidentiality) and (D) Section 13 (Amendments and Waivers) hereof (which rights, in each case of the foregoing clauses (A), (B), (C) and (D), shall be with respect to specific performance only and for no other purpose, including any claim for monetary damages). Each Sponsor hereby agrees not to oppose the granting of an injunction, specific performance or other equitable relief on the basis that Parent or the Company, as applicable, has an adequate remedy at law.

 

7.            No Assignment. This letter and the Commitments of the Sponsors described herein shall not be assignable by Parent without the prior written consent of the Sponsors and the Company (with the prior approval of the Special Committee), and the granting of such consent in a given instance shall be solely in the discretion of the Sponsors and the Company and, if granted, shall not constitute a waiver of this requirement as to any subsequent assignment. No assignment (in whole or in part) by a Sponsor of its rights or obligations hereunder shall be permitted without the prior written consent of Parent and the Company (with the prior approval of the Special Committee). Notwithstanding the foregoing, each Sponsor may, without consent, assign all or a portion of its Commitment hereunder to one or more of its Affiliates, including the other Sponsor (any such Affiliate, a “Permitted Assignee”); provided, that no such assignment or transfer to a Permitted Assignee shall (i) relieve a Sponsor of any part of its obligations hereunder, except on a dollar-for-dollar basis in respect of any portion of its Commitment actually funded by such Permitted Assignee pursuant to the assigning Sponsor’s Commitment under this letter or (ii) prevent, materially impair or delay the Closing. Any purported assignment or transfer in violation of this Section 7 (No Assignment) shall be null and void.

8.            Entire Agreement. This letter, together with the Merger Agreement and the Guarantee, constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof or thereof.

 

9.            Severability. In the event that any provision of this letter, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, or incapable of being enforced under any applicable Law, the remainder of this letter will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties. The parties further agree to replace such void or unenforceable provision of this letter with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

 

10.          Governing Law; Jurisdiction and Forum. This letter and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this letter or the actions of Parent and Sponsors in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with the Laws of the State of Delaware, including its statute of limitations, without giving effect to any choice or conflict of Laws (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. Each of the parties (a) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding relating to this letter, for and on behalf of itself or any of its properties or assets, in any manner as may be permitted by applicable Law; (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) (the “Chosen Courts”) in the event that any dispute or controversy arises out of this letter or the transactions contemplated hereby; (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (d) agrees that any Legal Proceeding arising in connection with this letter or the transactions contemplated hereby or thereby shall be brought, tried and determined only in the Chosen Courts; (e) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (f)   agrees that it shall not bring any Legal Proceeding relating to this letter or the transactions contemplated hereby in any court other than the Chosen Courts. Each of Parent and the Sponsors agrees that a final judgment in any Legal Proceeding in the Chosen Courts will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

Exhibit (d)(vii)

 

Limited Guarantee

 

This Limited Guarantee, dated as of March 8, 2023 (this “Guarantee”), is made by Platinum Equity Capital Partners IV, L.P., a Delaware limited partnership and Platinum Equity Capital Partners V, L.P., a Delaware limited partnership (each, a “Guarantor” and, together, the “Guarantors”) in favor of Diversey Holdings, Ltd., a Cayman Islands exempted company (the “Guaranteed Party”). Capitalized terms used but not defined herein have the meanings ascribed to them in the Merger Agreement (as defined below).

 

1.Limited Guarantee.

 

(a)           In connection with the execution and delivery, as of the date hereof, of the Agreement and Plan of Merger, by and among OLYMPUS WATER HOLDINGS IV, L.P., a Cayman Islands exempted limited company, acting by its general partner, General Partner (“Parent”), DIAMOND MERGER LIMITED, a Cayman Islands exempted company and a wholly-owned Subsidiary of Parent (“Merger Sub”), and the Guaranteed Party (as the same may be amended from time to time, the “Merger Agreement”), each Guarantor hereby unconditionally and irrevocably guarantees, as a primary obligor and not merely as a surety, to the Guaranteed Party, the due and punctual observance, performance, and discharge of the payment obligations of Parent and Merger Sub with respect to such Guarantor’s Pro Rata Portion (as defined below) of (i) the Parent Termination Fee, (ii) the Reimbursement Obligations in an amount not to exceed $7,500,000 in the aggregate, and (iii) any interest on the Parent Termination Fee and any out-of-pocket costs and expenses (including attorneys’ fees), in each case, required to be paid by Parent to the Company pursuant to Section 8.3(e) (Payments; Default) of the Merger Agreement (clauses (i) through (iii) collectively, the “Obligations”). The guaranties and obligations of the Guarantors shall be several and not joint, which shall mean that a Guarantor shall be liable to the Guaranteed Party only to the extent of such Guarantor’s Pro Rata Portion of the Obligations. The Guaranteed Party hereby agrees that in no event shall a Guarantor be required to pay any amount to the Guaranteed Party or any other Person under, in respect of, or in connection with this Guarantee, the Merger Agreement or the Equity Commitment Letter other than as expressly set forth herein or therein.

(b)          The maximum aggregate amount of liability of the Guarantors shall not exceed the amount of the Obligations, which shall be reduced on a dollar-for-dollar basis by any payments of cash actually made to the Guaranteed Party by such Guarantor or its permitted assignee pursuant to Section 5 in respect of the Obligations (such maximum amount as it may be reduced from time to time as described in this sentence, the “Maximum Amount”). This Guarantee may not be enforced against a Guarantor with respect to any amounts in excess of such Guarantor’s Pro Rata Portion of the Maximum Amount. The term “Pro Rata Portion” means (A) with respect to Platinum Equity Capital Partners IV, L.P., 31.58% and (B) with respect to Platinum Equity Capital Partners V, L.P., 68.42%, provided, that each Guarantor’s Pro Rata Portion shall be automatically adjusted to reflect any valid assignment by a Guarantor of any portion of such Guarantor’s commitment under the Equity Commitment Letter to the other Guarantor pursuant to, and in accordance with, Section 7 (No Assignment) thereof.

 

 

 

(c)           Promptly upon receipt of any written notice from the Guaranteed Party that Parent and Merger Sub have failed to pay the Obligations due in accordance with the terms of the Merger Agreement, each Guarantor shall promptly (and in any event within such time as required under the Merger Agreement after receipt of the Guaranteed Party’s written notice) pay in full its Pro Rata Portion of the amount of the required payment.

(d)           This Guarantee is an unconditional guaranty of payment and not of collection.

(e)           All payments hereunder shall be made in lawful money of the United States, in immediately available funds.

2.Changes in Obligations; Certain Waivers.

(a)           Each Guarantor agrees that the Guaranteed Party (with the prior written notice of the Special Committee) may at any time and from time to time, without notice to or further consent of the Guarantor, extend the time of payment of the Obligations, and may also enter into any agreement with Parent, Merger Sub or with any other Person interested in the transactions contemplated by the Merger Agreement, for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms of the Merger Agreement or of any agreement between the Guaranteed Party and Parent or any such other Person without in any way impairing or affecting such Guarantor’s Obligations under this Guarantee. Each Guarantor agrees that the Obligations hereunder shall to the fullest extent permitted by applicable Law, be absolute, unconditional and irrevocable irrespective of, and shall not be released or discharged, in whole or in part, or otherwise affected by:

(i)            the failure or delay of the Guaranteed Party to assert any claim or demand or to enforce any right or remedy against Parent, Merger Sub, any Guarantor or any other Person;

(ii)           the addition, substitution or release of any Person now or hereafter liable with respect to the Obligations to or from this Guarantee, the Merger Agreement, the Equity Commitment Letter or any related agreement or document or otherwise interested in the transactions contemplated by the Merger Agreement;

(iii)          any change in the corporate existence, structure or ownership of Parent, Merger Sub, the Guarantors or any other Person;

(iv)         any voluntary or involuntary liquidation, dissolution, marshalling of assets and liabilities, receivership, insolvency, bankruptcy, reorganization, moratorium, assignment for the benefit of creditors or other similar proceeding affecting Parent, Merger Sub, the Guarantors or any other Person or any of their respective assets;

 2 

 

 

(v)            the existence of any claim, set-off or other right which a Guarantor may have at any time against Parent or Merger Sub or any of their respective Affiliates, whether in connection with the Obligations or otherwise;

(vi)           any change in the time, place or manner of payment of the Obligations or any rescission, waiver, compromise, consolidation or other amendment or modification of any of the terms or provisions of the Merger Agreement or any other agreement evidencing, securing or otherwise executed in connection with the Obligations made accordance with the terms thereof;

(vii)          the adequacy or potential adequacy of any other means the Guaranteed Party may have of obtaining payment of the Obligations;

(viii)        without limiting the rights of each Guarantor set forth in Section 2(d), the genuineness, validity, illegality or enforceability of the Merger Agreement, the Commitment Letters, the definitive documents for the Debt Financing or any other agreement or instrument related thereto or referred to herein or in the Merger Agreement; or

(ix)           any other act or omission that may or might in any manner or to any extent vary or reduce the obligation of the Guarantor or otherwise operate as a discharge of a Guarantor as a matter of applicable Law or equity.

(b)            To the fullest extent permitted by applicable Laws, each Guarantor hereby expressly waives any and all rights or defenses arising by reason of any applicable Laws that would otherwise require any election of remedies by the Guaranteed Party. Each Guarantor waives promptness, diligence, notice of the acceptance of this Guarantee and of the Obligations, presentment, demand for payment, notice of non-performance, default, dishonor and protest, notice of the incurrence of any of the Obligations and all other notices of any kind (other than notices expressly required to be provided to Parent in accordance with the Merger Agreement), all defenses which may be available by virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any right to require the marshalling of the assets of Parent or any other Person interested in the transactions contemplated by the Merger Agreement, and all suretyship defenses generally (other than defenses to the payment of the Obligations that are available to Parent under the Merger Agreement or a breach by the Guaranteed Party of this Guarantee). Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the transactions contemplated by the Merger Agreement and that the waivers set forth in this Guarantee are knowingly made in contemplation of such benefits. All obligations to which this Guarantee applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. The Guaranteed Party shall not be obligated to file any claim relating to the Obligations in the event that Merger Sub becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Guaranteed Party to so file shall not affect a Guarantor’s obligations hereunder.

(c)           The Guaranteed Party hereby covenants and agrees that it shall not institute, and shall cause its controlled Affiliates not to institute, any proceeding or bring any other claim arising under, or in connection with, the Equity Commitment Letter or the Merger Agreement or the transactions contemplated thereby, against any Guarantor or any Guarantor Affiliate (as defined below), except for (i) claims against a Guarantor (or its Permitted Assignees (as defined in the Equity Commitment Letter)) or Parent under the Equity Commitment Letter, solely to the extent expressly provided therein (subject to the terms set forth therein and in the Merger Agreement), (ii) claims against a Guarantor (or its permitted assignees) under this Guarantee (subject to the terms herein), (iii) any claim by the Guaranteed Party against Parent or Merger Sub, to the extent permitted, under the Merger Agreement and (iv) claims by the Guaranteed Party against the parties to the Confidentiality Agreement, subject to the terms of the Confidentiality Agreement (clauses (i) to (iv), collectively, the “Permitted Claims”), and each Guarantor hereby covenants and agrees that it shall not institute, and shall cause its controlled Affiliates not to institute, any proceeding asserting that this Guarantee is illegal, invalid or unenforceable in accordance with its terms.

(d)           Notwithstanding any other provision of this Guarantee, the Guaranteed Party hereby agrees that (i) the Guarantors may assert, as a defense to, or release or discharge of, any payment or performance by the Guarantors under this Guarantee, any claim, set-off, deduction, defense or release that Parent could assert against the Company under the terms of, or with respect to, the Merger Agreement. (including, without limitation, any such claim or defense that any Obligations are not then required to be due and payable by Parent pursuant to the terms and conditions of Article VIII (Termination) of the Merger Agreement and subject to the limitations on liability set forth therein and in Section 9.8(b) (Specific Performance) of the Merger Agreement) and (ii) to the extent Parent is relieved of all or any portion of the Obligations under the Merger Agreement, the Guarantors shall likewise automatically and without any further action on the part of any person be relieved of all or such portion, as applicable, of its obligations under this Guarantee (excluding, in the case of clauses (i) and (ii), any defense arising in connection with the insolvency, bankruptcy, reorganization, liquidation or other similar proceeding (or any consequence or effects thereof) with respect to Parent or Merger Sub or their respective assets).

3.             No Waiver; Cumulative Rights. No failure on the part of the Guaranteed Party to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Guaranteed Party of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power hereunder. Each and every right, remedy and power hereby granted to the Guaranteed Party or allowed it by applicable Laws or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Guaranteed Party at any time and from time to time.

4.Representations and Warranties.

(a)            Each Guarantor hereby represents and warrants to the Guaranteed Party as to itself, and not as to the other Guarantor, that:

(i)            such Guarantor is a duly organized and validly existing limited partnership in good standing under the laws of the State of Delaware;

 4 

 

 

(ii)          the execution, delivery and performance of this Guarantee have been duly authorized by all necessary action and do not contravene, conflict with or result in any violation of any provision of such Guarantor’s organizational documents or any applicable Law or contractual restriction binding on such Guarantor or its assets,

(iii)         it has all power and authority necessary to execute, deliver and perform this Guarantee, no internal corporate (or similar) approval of such Guarantor is required and this Guarantee has been duly executed and delivered by such Guarantor;

(iv)         this Guarantee constitutes a legal, valid and binding obligation of such Guarantor enforceable against the Guarantor in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting creditors’ rights generally, and (ii) general equitable principles (whether considered in a proceeding in equity or at law);

(v)          all consents, approvals, authorizations, permits of, filings with and notifications to, any Governmental Authority necessary for the due execution, delivery and performance of this Guarantee by such Guarantor have been obtained or made and all conditions thereof have been duly complied with, and no other action by, and no notice to or filing with, any Governmental Authority is required in connection with the execution, delivery or performance of this Guarantee by such Guarantor; and

(vi)         such Guarantor has the financial capacity to pay and perform its obligations under this Guarantee, and all funds necessary for the Guarantor to fulfill its Pro Rata Portion of the Obligations shall be available to such Guarantor for so long as this Guarantee shall remain in effect in accordance with Section 7 (Continuing Guarantee) hereof.

5.            Assignment. Neither the Guarantors, on the one hand, nor the Guaranteed Party, on the other hand, may assign, transfer or delegate their respective rights, interests or obligations hereunder to any other Person (except by operation of law) without the prior written consent of all the other parties hereto. Notwithstanding the foregoing, each Guarantor may assign its rights, interests or its Obligations hereunder to its Affiliates; provided, however, that no such assignment shall relieve such Guarantor of its Obligations hereunder except that such Guarantor’s Obligations hereunder shall be reduced on a dollar-for-dollar basis by any amounts actually paid in cash to the Guaranteed Party in respect of its Obligations hereunder by such permitted assignee. This Guarantee shall not be assigned by the Guaranteed Party (whether by operation of Law or otherwise), without the prior written consent of the Guarantors, or by any Guarantor (whether by operation of Law or otherwise), without the prior written consent of the Guaranteed Party (which consent shall have been approved in writing by the Special Committee); provided that any adjustment between Guarantors’ respective Pro Rata Portions pursuant to Section 1(b) shall not require the consent of the Guaranteed Party, provided that such assignment will not prevent, materially impair or delay the Closing. Any attempted assignment in violation of this section shall be null and void.

7.              Continuing Guarantee. Unless terminated pursuant to this Section 7 (Continuing Guarantee), this Guarantee is a continuing one and may not be revoked or terminated and shall remain in full force and effect and shall be binding on the Guarantors, their successors and permitted assigns, and shall inure to the benefit of, and be enforceable by, the Guaranteed Party and its respective successors and permitted transferees and assigns, until the Obligations have been paid, observed, performed or satisfied in full, at which time this Guarantee shall immediately and automatically terminate and the Guarantors shall have no further obligations under this Guarantee. Notwithstanding the foregoing, this Guarantee shall terminate automatically and the Guarantors shall have no further obligations under this Guarantee immediately as of the earliest to occur of (i) the consummation of the Closing and the payment of Closing Payments (as defined in the Equity Commitment Letter) in connection therewith, (ii) payment in full of the Obligations pursuant to this Guarantee, (iii) valid termination of the Merger Agreement in accordance with its terms in any circumstances other than pursuant to which Parent would be obligated to make a payment of any portion of the Obligations and (iv) the date that is 90 days after the valid termination of the Merger Agreement in accordance with its terms in any circumstances pursuant to which Parent would be obligated to make a payment in respect of any portion of the Obligations (any such termination, a “Qualifying Termination”)), unless prior to the end of the 90th day after a Qualifying Termination, the Guaranteed Party shall have commenced a suit, action or other proceeding against Parent alleging payment of any Obligations due and owing or against a Guarantor that amounts are due and owing from the Guarantors pursuant to Section 1 (Limited Guarantee) hereof (a “Qualifying Suit”); provided that if a Qualifying Termination has occurred and a Qualifying Suit is filed prior to the end of the 90th day after a Qualifying Termination, the Guarantors shall not have any further liability or obligation under this Guarantee from and after the earliest of (w) the consummation of the Closing in accordance with the terms of the Merger Agreement, including payment of the Closing Payments (as defined in the Equity Commitment Letter) in accordance with the Merger Agreement, (x) a final, non-appealable resolution of such Qualifying Suit determining that the Guarantors do not owe any amount pursuant to this Guarantee, (y) a written agreement among the Guarantors and the Guaranteed Party expressly terminating this Guarantee, and (z) satisfaction in full of the Guarantors’ Obligations by the Guarantors or Parent. Notwithstanding the foregoing, in the event that the Guaranteed Party or its Subsidiaries, or any of their respective directors or officers acting on their behalf or controlled Affiliates or Bain or its Subsidiaries, or any of their respective directors or officers acting on their behalf or controlled Affiliates (A) file or otherwise commence (or encourage, facilitate or support any other person to file or commence) any lawsuit or other legal proceeding asserting a claim that the provisions of this Guarantee limiting a Guarantor’s liability to its Pro Rata Portion of the Obligations or its Pro Rata Portion of the Maximum Amount, or any provisions of this Guarantee are illegal, invalid or unenforceable in whole or in part, or assert any theory of liability against any Guarantor or any Guarantor Affiliate with respect to the transactions contemplated by the Merger Agreement other than any Permitted Claim or (B) assert, file or otherwise commence, directly or indirectly, any lawsuit or other legal proceeding asserting a claim under, or action against, any Guarantor Affiliate in connection with this Guarantee, the Equity Commitment Letter, the Merger Agreement, the Debt Commitment Letters or any transaction contemplated hereby or thereby or otherwise relating hereto or thereto, in each case other than any Permitted Claim, then (W) the obligations of the Guarantors under this Guarantee shall terminate ab initio and be null and void, (X) if a Guarantor has previously made any payments under this Guarantee, such Guarantor shall be entitled to recover such payments, (Y) the Guarantors shall be entitled to recover from the Guaranteed Party the costs and expenses incurred by the Guarantors or any Guarantor Affiliate in connection with the defense of any such claims or the enforcement of their respective rights under this Guarantee, the Equity Commitment Letter, the Merger Agreement, the Debt Commitment Letters or any transaction contemplated hereby or thereby or otherwise relating hereto or thereto and (Z) neither the Guarantors nor any of its Affiliates shall have any liability to the Guaranteed Party or any of its Affiliates with respect to the transactions contemplated by the Merger Agreement, under this Guarantee or otherwise.

8.             No Recourse. The Guaranteed Party acknowledges the separate corporate existence of Parent and that, as of the date hereof, Parent’s sole assets (if any) are a de minimis amount of cash and the rights of Parent pursuant to the Equity Commitment Letter, the Debt Commitment Letter and the Merger Agreement, and that no additional funds are expected to be contributed to Parent unless and until the Closing occurs. Notwithstanding anything that may be expressed or implied in this Guarantee or any document or instrument delivered contemporaneously herewith, by its acceptance of the benefits of this Guarantee, but without limiting any Permitted Claims, the Guaranteed Party acknowledges and agrees that it will not seek, has no rights of recovery against, and no personal liability shall attach to, any former, current or future director, officer, employee, direct or indirect equityholder, controlling person, general or limited partner, manager, member, stockholder, Affiliate (other than Parent and Merger Sub), agent, successor or assign (other than any successor or assignee under Section 5 hereof) of any Guarantor or any former, current or future director, officer, employee, direct or indirect equityholder, controlling person, general or limited partner, manager, member, stockholder, Affiliate, agent, successor or assign (other than any successor or assignee under Section 5 hereof) of any of the foregoing (not including Parent or Merger Sub, each a “Guarantor Affiliate” and collectively, the “Guarantor Affiliates”; it being understood that the term Guarantor Affiliate shall not include the Guarantors, Parent or Merger Sub or any Person to which (x) Parent or Merger Sub have assigned their respective rights or obligations under the Merger Agreement in accordance with the Merger Agreement or (y) any Guarantor has validly assigned all or any portion of its Commitment (as defined in the Equity Commitment Letter) or its Obligations), through Parent, any Guarantor or otherwise, whether by or through attempted piercing of the corporate veil, by or through a claim by or on behalf of Parent against any Guarantor Affiliate, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any applicable Laws, or otherwise, except for any Permitted Claims. Notwithstanding anything to the contrary herein, with the exception of the rights set forth in clauses (i), (ii), (iii) and (iv) immediately above, recourse against the Guarantors under this Guarantee shall be the sole and exclusive remedy of the Guaranteed Party and its controlled Affiliates and equityholders against the Guarantors and Parent in respect of any liabilities or obligations arising under, or in connection with, the Merger Agreement, this Guarantee or the transactions contemplated thereby or hereby. Nothing set forth in this Guarantee shall affect or be construed to affect any liability of Parent to the Guaranteed Party or shall confer or give or shall be construed to confer or give to any Person other than the Guaranteed Party (including any Person acting in a representative capacity) any rights or remedies against any Person other than the Guarantors as expressly set forth herein. This Section 8 (No Recourse) shall survive the termination of this Guarantee.

9.              Governing Law; Jurisdiction and Forum. This Guarantee and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Guarantee or the actions of the Guaranteed Party or Guarantors in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with the Laws of the State of Delaware, including its statute of limitations, without giving effect to any choice or conflict of Laws (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. Each of the parties (a) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding relating to this Guarantee, for and on behalf of itself or any of its properties or assets, in accordance with Section 6 or in such other manner as may be permitted by applicable Law, and nothing in this Section 9 will affect the right of any party to serve legal process in any other manner permitted by applicable Law; (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive general jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) (the “Chosen Courts”) in the event that any dispute or controversy arises out of this Guarantee or the transactions contemplated hereby; (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (d) agrees that any Legal Proceeding arising in connection with this Guarantee or the transactions contemplated hereby shall be brought, tried and determined only in the Chosen Courts; (e) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (f) agrees that it shall not bring any Legal Proceeding relating to this Guarantee or the transactions contemplated hereby in any court other than the Chosen Courts. Each of Guaranteed Party and the Guarantors agrees that a final judgment in any Legal Proceeding in the Chosen Courts will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

10.           Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS GUARANTEE IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTEE. EACH PARTY ACKNOWLEDGES AND AGREES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (ii) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (iii)   IT MAKES THIS WAIVER VOLUNTARILY; AND (iv) IT HAS BEEN INDUCED TO ENTER INTO THIS GUARANTEE BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10 (WAIVER OF JURY TRIAL).

11.            Severability. In the event that any provision of this Guarantee, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, or incapable of being enforced under any applicable Law, the remainder of this Guarantee will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties. The parties further agree to replace such void or unenforceable provision of this Guarantee with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision. Notwithstanding anything to the contrary in this Guarantee, this Guarantee may not be enforced without giving effect to the limitation of the amount payable hereunder with respect to the Obligations provided in Section 1 (Limited Guarantee) hereof and to the provisions of Section 7 (Continuing Guarantee), Section 8 (No Recourse) and Section 2(d) (Changes in Obligations; Certain Waivers) hereof. No party hereto shall assert, and each party shall cause its respective controlled affiliates not to assert, that this Guarantee or any part hereof is invalid, illegal or unenforceable.

12.           Confidentiality. This Guarantee shall be treated as confidential and is being provided to the Guaranteed Party solely in connection with the execution and delivery of the Merger Agreement. This Guarantee may not be used, circulated, quoted or otherwise referred to in any document, except with the written consent of the Guarantors and the Guaranteed Party; provided, that no such written consent shall be required (and the Guarantors, the Guaranteed Party and their respective Affiliates shall be free to release such information) for disclosures to such person’s respective members, limited partners, securityholders, advisors and representatives on a need-to-know basis, so long as such persons agree to keep such information confidential on terms substantially identical to the terms contained in this Section 12 (Confidentiality); provided,further, that the Guarantors and the Guaranteed Party may disclose this Guarantee to the extent required by Law, the applicable rules of any national securities exchange or required or requested by the United States Securities and Exchange Commission.

13.           Counterparts; Electronic Execution. This Guarantee may be executed in one or more counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each party forever waives any such defense, except to the extent such defense relates to lack of authenticity.

14.           Entire Agreement. This Guarantee, the Equity Commitment Letter and the Merger Agreement constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof.

15.           Amendments and Waivers. No amendment, supplement, modification or waiver of any provision of this Guarantee will be valid and binding unless it is in writing and signed by the Guarantors and the Guaranteed Party (which amendment, supplement, modification or waiver must be approved in writing by the Special Committee). No waiver by any party hereto shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver.

16.           Headings. Section headings in this Guarantee are for convenience of reference only and shall not govern the interpretation of any provision of this Guarantee.

 10 

 

 

17.            No Presumption Against Drafting Party. Each party acknowledges that it and its counsel have been given an equal opportunity to negotiate the terms and conditions of this Guarantee and that any rule of construction to the effect that ambiguities are to be resolved against the drafting party or any similar rule operating against the drafter of an agreement are not applicable to the construction or interpretation of this Guarantee.

(1) Aggregate number of securities to which transaction applies: As of March 31, 2023, the maximum number of the Registrant’s ordinary shares to which this transaction applies is estimated to be 329,650,466, which consists of (1) 236,983,211 ordinary shares held by BCPE Diamond Investor, LP, (“BCPE”) entitled to receive $7.84 per ordinary share in connection with the transaction; (2) 87,580,048 ordinary shares entitled to receive $8.40 per ordinary share in connection with the transaction; and (3) 5,087,207 ordinary shares underlying outstanding restricted share units and performance share units, which are entitled to receive $8.40 per ordinary share in connection with the transaction (subject, in some cases, to time-based vesting).

 

(2) Per unit price or other underlying value of transaction computed pursuant to Exchange Act Rule 0-11 (set forth the amount on which the filing fee is calculated and state how it was determined): Estimated solely for the purposes of calculating the filing fee, as of March 31, 2023, the underlying value of the transaction was calculated based on the sum of (1) the product of 236,983,211 ordinary shares held by BCPE and the per share merger consideration of $7.84 applicable to such shares; (2) the product of 87,580,048 ordinary shares not held by BCPE and the per share merger consideration of $8.40 applicable to such shares; and (3) the product of 5,087,207 ordinary shares underlying outstanding restricted share units and performance share units and the per share merger consideration of $8.40 applicable to such units (subject, in some cases, to time-based vesting). In accordance with Section 14(g) of the Securities Exchange Act of 1934, as amended, the filing fee was determined by multiplying the sum calculated in the preceding sentence by .0001102.

 

(3) Diversey Holdings, Ltd. previously paid $290,526.14 upon the filing of its Schedule 14A on April 11, 2023 in connection with the transaction reported hereby.
