Redemption Offset Agreement

As previously disclosed, on July 18, 2021, Investindustrial Acquisition Corp, a Cayman Islands exempted company (“IIAC”), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), by and among IIAC, Ermenegildo Zegna Holditalia SpA, a joint stock company incorporated under Italian law (“Zegna”) and EZ Cayman, a Cayman Islands exempted company.

On December 3, 2021, IIAC, Zegna and certain subscribers (the “Subscribers”) entered into Redemption Offset Agreements (the “Redemption Offset Agreements”), pursuant to which the Subscribers agreed to subscribe for ordinary shares of Zegna at the Closing to offset redemptions of IIAC’s Class A ordinary shares by IIAC public shareholders up to a certain level if the redemptions exceed the Redemption Threshold Amount (as defined in each Redemption Offset Agreement). The Redemption Offset Agreements provide, among other things, that (i) in the event the amount required to be released from IIAC’s Trust Account (as defined in the Business Combination Agreement) as a result of redemptions by the public shareholders of IIAC exceeds the Redemption Threshold Amount, then the Subscribers shall subscribe for and purchase, and Zegna shall issue to the Subscribers (each pro rata to their maximum committed amount) an aggregate number of Company Ordinary Shares (as defined in the Business Combination Agreement) equal to the lesser of (x) the number of Redeemed IIAC Shares (as defined in the Redemption Offset Agreement) and (y) 12,500,000; (ii) any Company Ordinary Shares to be issued by Zegna to the Subscribers will be issued at Closing (as defined in the Business Combination Agreement) at the price of $10.00 per share; and (iii) for purposes of determining the Aggregate PIPE Proceeds under the Business Combination Agreement, any subscription agreements entered into pursuant to the Redemption Offset Agreements by the Subscribers shall constitute a part of the PIPE Financing (as defined in the Business Combination Agreement).

A copy of the form of Redemption Offset Agreement is filed with this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference, and the foregoing description of the Redemption Offset Agreements is qualified in its entirety by reference thereto.

On December 6, 2021, IIAC and Zegna issued a joint press release announcing, amongst other things, the time and date of the extraordinary general meeting of IIAC to approve the Business Combination and their entry into the Redemption Offset Agreements. The press release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

The foregoing (including Exhibit 99.1) is being furnished pursuant to Item 7.01 and will not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor will it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended or the Exchange Act regardless of any general incorporation language in such filings. This Current Report will not be deemed an admission of materiality of any of the information in this Item 7.01, including Exhibit 99.1.

Additional Information

In connection with the Business Combination, Zegna has filed a registration statement on Form F-4 (File No. 333-259139) with the Securities and Exchange Commission (the “SEC”) (the “Registration Statement”) that includes a prospectus with respect to Zegna’s securities to be issued in connection with the transactions contemplated by the Business Combination Agreement and a proxy statement with respect to the shareholder meeting of IIAC to vote on the Business Combination. The Registration Statement has been declared effective by the SEC and mailed to IIAC’s shareholders. Shareholders of IIAC and other interested persons are urged to read the definitive proxy statement/prospectus as well as other documents to be filed with the SEC because these documents contain important information about IIAC, Zegna and the Business Combination. Shareholders of IIAC may also obtain a copy of the F-4, including the definitive proxy statement/prospectus, and other documents to be filed with the SEC without charge, by directing a request to: Investindustrial Acquisition Corp., Suite 1, 3rd Floor, 11-12 St. James’s Square, London, United Kingdom SW1Y 4LB. The definitive proxy statement/prospectus included in the registration statement can also be obtained, without charge, at the SEC’s website (www.sec.gov).

Participants in the Solicitation

IIAC and Zegna and their respective directors and executive officers may be considered participants in the solicitation of proxies with respect to the Business Combination described in this communication under the rules of the SEC. Information about the directors and executive officers of IIAC and their ownership is set forth in IIAC’s filings with the SEC, including its Form 10-K for the year ended December 31, 2020 and subsequent filings on Form 10-Q and Form 4. Additional information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of the IIAC shareholders in connection with the Business Combination is set forth in the Registration Statement and definitive proxy statement/prospectus filed with the SEC. These documents can be obtained free of charge from the sources indicated above.

Forward Looking Statements

This communication contains forward-looking statements within the meaning of section 27A of the Securities Act and Section 21E of the Exchange Act that are based on beliefs and assumptions and on information currently available to Zegna and IIAC. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including strategies or plans as they relate to the Business Combination, are also forward-looking statements. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although each of Zegna and IIAC believes that it has a reasonable basis for each forward-looking statement contained in this communication, each of Zegna and IIAC caution you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, risks and uncertainties are described in the Registration Statement and definitive proxy statement/prospectus relating to the Business Combination filed by Zegna with the SEC and other documents filed by Zegna and IIAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Most of these factors are outside Zegna’s and IIAC’s control and are difficult to predict. Forward-looking statements in this communication include, but are not limited to, statements regarding the Business Combination, including the timing and structure of the transaction, the proceeds of the transaction and the benefits of the Business Combination. Neither Zegna nor IIAC can assure you that the forward-looking statements in this communication will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the risk that the Business Combination may not be completed in a timely manner or at all, the ability to complete the Business Combination due to the failure to obtain approval from IIAC’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to the termination of the Business Combination Agreement or the termination of any PIPE investor’s subscription agreement, the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination, the ability to recognize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the Business Combination, the amount of redemption requests made by IIAC’s public shareholders, costs related to the Business Combination, the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination, general economic, political and business conditions, applicable taxes, inflation, interest rates and the regulatory environment, the risk that Zegna may not be able to maintain the recognition, integrity or reputation of its brands or is unable to anticipate trends and identify and respond to new and changing consumer preferences, Zegna’s failure to implement its strategy, any disruption in Zegna’s manufacturing and logistics facilities, fluctuations in the price or quality of, or disruptions in the availability of, raw materials used in Zegna’s products, Zegna’s inability to negotiate, maintain or renew its license agreements and strategic alliances, the outcome of any potential litigation, government or regulatory proceedings, changes in macro-economic conditions and tourist traffic and demand, Zegna’s ability to retain certain key personnel and craftsmen, any disruption in Zegna’s information technology, including as a result of cybercrimes, Zegna’s competitive position, risks related to Zegna’s management team’s limited experience in managing a public company, Zegna’s intellectual property position, including its ability to protect and maintain its intellectual property rights, fluctuations in foreign currency exchange rates that could result in currency transaction losses that negatively impact Zegna’s financial results and the anticipated transaction proceed uses and sources, the ability of the combined company to grow and manage growth profitably and retain its key employees, the inability to obtain or maintain the listing of the combined company’s securities on the New York Stock Exchange following the business combination, the impact of the global COVID-19 pandemic on any of the foregoing, and other risks and uncertainties, including those included

under the heading “Risk Factors” in the Registration Statement on Form F-4 filed by Zegna with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2020 of IIAC and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by Zegna, IIAC, their respective directors, officers or employees or any other person that Zegna and IIAC will achieve their objectives and plans in any specified time frame, or at all. The forward-looking statements in this communication represent the views of Zegna and IIAC as of the date of this communication. Subsequent events and developments may cause that view to change. However, while Zegna and IIAC may elect to update these forward-looking statements at some point in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of Zegna or IIAC as of any date subsequent to the date of this communication.

No Offer or Solicitation

This communication is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination and does not constitute an offer to sell or a solicitation of an offer to buy any securities of IIAC or Zegna, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended.

A. Subscription. If the Actual Redemption Amount exceeds the Redemption Threshold Amount, then Subscriber shall subscribe for and purchase in cash at the Share Purchase Price and the Company shall issue to Subscriber at the Closing, the number of Company Ordinary Shares equal to the lesser of (x) the product obtained by multiplying (i) the number of Redeemed IIAC Shares by (ii) a fraction, the numerator of which is the Maximum Subscriber Shares, and the denominator of which is the Maximum Redemption Offset Subscribers Shares (rounded down to the nearest whole Company Ordinary Share) and (y) the Maximum Subscriber Shares (such number of shares, the “Acquired Shares”).

B. Closing Procedures. No later than the day of the IIAC Shareholders Meeting, the Company shall provide written notice (which may be via email) to Subscriber (the “Closing Notice”), which Closing Notice shall contain the number of Acquired Shares to be purchased by Subscriber (based on the calculation in Section 2.A above) and the Company’s wire instructions for an account established by the Company for the purpose of collecting funds in advance of the closing of this subscription.

(ii) Subscriber acknowledges and agrees that the Acquired Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Acquired Shares have not been registered under the Securities Act. The Subscriber acknowledges and agrees that the Acquired Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act except (i) to Company or a subsidiary thereof, (ii) in an “offshore transaction” within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and in each of clauses (ii) and (iii) in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates representing the Acquired Shares shall contain the restrictive legend set forth in the Subscription Agreement.

(iii) Subscriber understands and agrees that Subscriber is purchasing the Acquired Shares directly from the Company. Subscriber further acknowledges that there have been no representations, warranties, covenants and agreements made to Subscriber by or on behalf of the Company, IIAC or any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements included in this Agreement and those representations, warranties, covenants and agreements that may be made in the Subscription Agreement.

(iv) Subscriber’s acquisition and holding of the Acquired Shares will not constitute or result in a non-exempt prohibited transaction under section 406 of the Employee Retirement Income Security Act of 1974, as amended, section 4975 of the Internal Revenue Code of 1986, as amended, or any applicable similar law.

(v) In making its decision to subscribe for and purchase the Acquired Shares, Subscriber represents that it has relied solely upon its own independent analysis and investigation. Without limiting the generality of the foregoing, Subscriber has not relied on any statements, representations, warranty or other information provided by IIAC (other than the representations, warranties, covenants and agreements of IIAC in this Agreement and those representations, warranties, covenants and agreements of IIAC that may be made in the Subscription Agreement), or Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities PLC and/or UBS Securities LLC (collectively, the “Placement Agents”) or any of their affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing concerning the Company or the Acquired Shares or the offer and sale of the Acquired Shares.

Subscriber acknowledges and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Acquired Shares, including but not limited to access to marketing materials. Subscriber acknowledges that certain information provided by the Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections.

(vi) Subscriber became aware of this offering of the Acquired Shares solely by means of direct contact between Subscriber and the Company, IIAC, the Placement Agents or a representative of the Company, IIAC or the Placement Agents, and the Acquired Shares were offered to Subscriber solely by direct contact between Subscriber and the Company or the Placement Agents.

Subscriber acknowledges that the Company represents and warrants that the Acquired Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

(vii) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Acquired Shares, including but not limited to those set forth in the Company’s and IIAC’s filings with the SEC. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Acquired Shares, and Subscriber has sought such accounting, legal and tax advice as Subscriber has considered necessary to make an informed investment decision. Subscriber has made its own assessment and has satisfied itself concerning relevant tax and other economic considerations relative to its purchase of the Acquired Shares. Subscriber will not look to the Placement Agents or any of their affiliates or representatives for all or part of any such loss or losses Subscriber may suffer.

(viii) Subscriber acknowledges and agrees that neither the Placement Agents nor any affiliate or representative of the Placement Agents has provided Subscriber with any information or advice with respect to the Acquired Shares nor is such information or advice necessary or desired. Subscriber acknowledges that the Placement Agents and their affiliates and representatives (i) have not made any representation as to the Company or the quality of the Acquired Shares, (ii) may have acquired non-public information with respect to the Company which Subscriber agrees need not be provided to it, (iii) have made no independent investigation with respect to the Company or the Acquired Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Company, (iv) have not acted as Subscriber’s financial advisor or fiduciary in connection with the issue and purchase of the Acquired Shares and (v) have not prepared a disclosure or offering document in connection with the offer and sale of the Acquired Shares. Subscriber further acknowledges that the Placement Agents may have existing or future business relationships with IIAC and the Company, including, but not limited to, acting as financial advisors for the Transaction.

(ix) Subscriber represents and acknowledges that Subscriber, alone, or together with any professional advisor(s), has adequately analyzed and fully considered the risks of an investment in the Acquired Shares and determined that the Acquired Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

(x) Subscriber understands and acknowledges that no federal or state agency has passed upon or endorsed the merits of the offering of the Acquired Shares or made any findings or determination as to the fairness of an investment in the Acquired Shares.

(xi) Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification List, each of which is administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) (collectively “OFAC Lists”), (ii) owned or controlled by, or acting on behalf of, a person, that is named on an OFAC List, (iii) organized, incorporated, established, located, resident or born in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, the Crimea region of Ukraine, or any other country or territory embargoed or subject to substantial trade restrictions by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R.

d. Further Assurances. Subject to the terms and conditions of this Agreement, the Parties agree to use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the transactions contemplated hereby. Subject to the terms and conditions of this Agreement, at a Party’s reasonable request and without further consideration, the other Parties shall execute and deliver to such requesting party such other instruments of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions as required in order to consummate the transactions contemplated hereby.

e. Captions. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement.

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

g. Amendment. This Agreement may be amended or modified only by a written agreement executed and delivered by the Parties. This Agreement may not be modified or amended except as provided in the immediately preceding sentence and any purported amendment or modification by any Party or Parties effected in a manner which does not comply with this Section 4(g) shall be void, ab initio.

h. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. In the event that any signature is delivered by facsimile transmission, email or any other form of electronic delivery, such signature shall create a valid and binding obligation of the Party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

i. Expenses. Except as otherwise set forth in this Agreement, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby, including the fees and disbursements of counsel, financial advisors and accountants, shall be paid by the Party incurring such fees or expenses.

j. Termination. This Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with the terms therein, (b) upon the mutual written agreement of each of the Parties to terminate this Agreement, (c) April 18, 2022 if the Closing has not occurred by such date, other than as a result of a breach of Subscriber’s obligations hereunder, or (d) the Actual Redemption Amount not exceeding the Redemption Threshold Amount (the termination events described in clauses (a) – (d) above, collectively, the “Termination Events”); provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. The Company shall notify Subscriber in writing of the termination of the Business Combination Agreement promptly after the termination of such agreement. Upon the occurrence of any Termination Event, any monies paid by Subscriber to the Company in connection herewith shall promptly (and in any event within one (1) Business Day) following the Termination Event be returned to Subscriber by wire transfer of immediately available funds to the account specified by Subscriber without any deduction for or on account of any tax, withholding, charges, or set-off.

-10-

k. No Hedging. The Subscriber agrees that, from the date of this Agreement until the Closing Date or the earlier termination of this Agreement, none of the Subscriber or any person or entity acting on behalf of the Subscriber or pursuant to any understanding with the Subscriber will engage in any hedging or other transactions or arrangements (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or similar instrument, including without limitation equity repurchase agreements and securities lending arrangements, however described or defined) designed or intended, or which could reasonably be expected to lead to or result in, a sale, loan, pledge or other disposition or transfer (whether by the Subscriber or any other person), in each case, solely to the extent it has the same economic effect as a “short sale” (as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act), of any economic consequences of ownership (excluding, for the avoidance of doubt, any consequences resulting solely from foreign exchange fluctuations), in whole or in part, directly or indirectly, physically or synthetically, of any Acquired Shares, any equity securities of IIAC or any instrument exchangeable for or convertible into any equity securities of the Company prior to the Closing, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of equity securities of the Company, in cash or otherwise, or to publicly disclose the intention to undertake any of the foregoing; provided, however, that the provisions of this Section 4(k) shall not apply to long sales (including sales of securities held by the Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates prior to the date of this Agreement and securities purchased by the Subscriber in the open market after the date of this Agreement). Notwithstanding the foregoing, nothing in this Section 4(k) shall prohibit any entities under common management with the Subscriber from entering into any of the transactions set forth in the first sentence of this Section 4(k) and in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, the restriction set forth in the first sentence of this Section 4(k) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Acquired Shares covered by this Agreement.

l. Disclosure. IIAC shall, within two (2) business days following the date of this Agreement (the “Disclosure Time”), issue one or more press releases or file with the SEC a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the agreements with the Other Subscribers and any other material, nonpublic information that IIAC or the Company has provided to Subscriber at any time prior to the filing of the Disclosure Document. From and after the issuance of the Disclosure Document, to the reasonable knowledge of IIAC and the Company, Subscriber shall not be in possession of any material, nonpublic information received from IIAC or the Company, or any of their respective officers, directors, employees, or agents, including, without limitation the Placement Agents. In addition, effective upon the earlier of the Disclosure Time and the filing or issuance of the Disclosure Document, each of IIAC and the Company acknowledges and agrees that any and all confidentiality or similar obligations under any current agreement, whether written or oral, with IIAC or the Company, or any of their respective subsidiaries or any of their respective officers, directors, affiliates, employees or agents, including, without limitation, any Placement Agents, on the one hand, and the Subscriber or any of its affiliates or investment advisers, on the other hand, shall terminate and be of no further force or effect. Each of IIAC and the Company understands and confirms that the Subscriber and its affiliates will rely on the foregoing representations in effecting transactions in securities of IIAC and the Company. Notwithstanding anything in this Agreement to the contrary, neither IIAC nor the Company shall publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers (i) in any press release marketing materials, without the prior written consent of Subscriber or (ii) in any filing with the SEC or any

-11-

regulatory agency or trading market, without the prior written consent of Subscriber, except (A) as required by the federal securities law or pursuant to other routine proceedings of regulatory authorities, or (B) to the extent such disclosure is required by law, at the request of the staff of the SEC or regulatory agency or under the regulations of any national securities exchange on which IIAC’s securities are listed for trading; provided, however, that in the case of clause (ii), the Company or IIAC, as applicable, shall provide the Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with the Subscriber regarding such disclosure.

m. Separate Obligations. For ease of administration, this single Redemption Offset Agreement is being executed so as to enable each Subscriber identified on the signature page to enter into a Redemption Offset Agreement, severally, but not jointly. The parties agree that (i) each Redemption Offset Agreement shall be treated as if it were a separate agreement with respect to each Subscriber listed on the signature page, as if each Subscriber entity had executed a separate Redemption Offset Agreement naming only itself as Subscriber, and (ii) no Subscriber listed on the signature page shall have any liability under the Redemption Offset Agreement for the obligations of any other Subscriber so listed. For the avoidance of doubt, all obligations of the Subscriber hereunder are separate and several from the obligations of any Other Subscriber. The decision of the Subscriber to enter into the transactions contemplated by this Redemption Offset Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as to the business, financial condition or results of operations of the Company, IIAC, or any of their respective subsidiaries which may have been made or given by any Other Subscriber or by any agent or employee of any Other Subscriber, and neither the Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any other Redemption Offset Agreement, and no action taken by the Subscriber or Other Subscribers pursuant hereto or thereto, shall be deemed to constitute the Subscriber and any Other Subscriber as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Subscriber and the Other Subscribers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Redemption Offset Agreement. The Subscriber acknowledges that no Other Subscriber has acted as agent for the Subscriber in connection with the transactions contemplated hereunder and no Other Subscriber will be acting as agent of the Subscriber in connection with monitoring its investment in the Acquired Shares or enforcing its rights hereunder. The Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Redemption Offset Agreement, and it shall not be necessary for any Other Subscriber to be joined as an additional party in any proceeding for such purpose.

Capitalized terms used and not otherwise defined in this Schedule have the meanings given to them in the Agreement.

1.                 ☐    We are a “non-U.S. person” (as defined in Regulation S under the Securities Act), and, if resident in a member state of the European Economic Area or the United Kingdom, not a retail investor. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”)); or (ii) a customer within the meaning of Directive 2016/97/EU, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the EEA or the United Kingdom has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the EEA or the United Kingdom may be unlawful under the PRIIPs Regulation. We did not receive in the United States any document related to the offer or sale of the Acquired Shares, and did not send any such document into the United States; we have not used, directly or indirectly, the mails, or a means of communication or other means or instrumentality of commerce or the facilities of a United States securities exchange in relation to the offer or sale of the Acquired Shares.

WHEREAS, in connection with the Transaction, on [•], 2021, Subscriber, IIAC and the Company entered into a Redemption Offset Agreement (the “Redemption Offset Agreement”), pursuant to which the Subscriber agreed to purchase from the Company, simultaneous with the closing of the Transaction, up to the number of ordinary shares of the Company (the “Common Shares”) set forth on the signature page thereto;

1

WHEREAS, in connection with the Transaction, certain other “qualified institutional buyers” (as such term is defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”)), “accredited investors” (as such term is defined in Rule 501 under the Securities Act) or “non-U.S. persons” (as defined in Regulation S under the Securities Act) (collectively, the “Other Subscribers” and together with the Subscriber, the “Subscribers”) that may include institutional investors, post-Closing directors of the Company, existing directors of Thom Browne, Inc. and/or their respective affiliates, have entered into, severally and not jointly, subscription agreements with the Company and IIAC substantially similar to this Subscription Agreement, pursuant to which such Other Subscribers, severally and not jointly, have agreed to subscribe for and purchase, and the Company has agreed to issue and sell to such Other Subscribers, severally and not jointly, on the Closing Date, Common Shares at the Share Purchase Price (the “Other Subscription Agreements”); and

WHEREAS, the Subscribers, severally and not jointly, have agreed to subscribe for and purchase, and the Company has agreed to issue and sell to such Subscribers, severally and not jointly, on the Closing Date, an aggregate amount of [•] Common Shares at the Share Purchase Price.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1.    Subscription. Subject to the terms and conditions hereof, the Subscriber hereby subscribes for and agrees to purchase from the Company, and the Company agrees to issue and sell to Subscriber, such number of Common Shares as is set forth on the signature page of this Subscription Agreement at the Share Purchase Price on the terms and subject to the conditions provided for herein. Notwithstanding the foregoing or anything to the contrary in Section 7 below, in the event that the Closing Date shall not have occurred by April 18, 2022, this Subscription Agreement shall be terminated and deemed void and of no further effect, and any monies paid by the Subscriber to the Company in connection herewith shall immediately be returned to the Subscriber. The Subscriber understands that the subscribed Common Shares that will be issued pursuant to this Subscription Agreement will be ordinary shares of the Company, as a Dutch public limited liability company (naamloze vennootschap) following the Company Conversion.

2.    Closing.

(a)    Subject to the satisfaction or waiver (in writing) of the conditions set forth in Section 2(d), (e) and (f), the closing of the subscription contemplated hereby (the “Closing”) shall occur after the Company Conversion and is contingent upon the substantially concurrent consummation of the Transaction and shall occur on the date of, and substantially concurrently with and conditioned upon the effectiveness of, the Transaction (such date, the “Closing Date”). Pursuant to the Redemption Offset Agreement, the Company shall provide the Closing Notice (as defined in the Redemption Offset Agreement) (which may be via email) to Subscriber, which Closing Notice shall also include the date on which the Company reasonably expects the Closing to occur (the “Scheduled Closing Date”).

(b)    As of the date of this Subscription Agreement, Subscriber shall deliver to the escrow account specified in the Closing Notice the Purchase Price by wire transfer of United States dollars in immediately available funds. Upon the Closing, the Company shall provide instructions to the escrow agent for the escrow account to release the Purchase Price in the escrow account to the Company against delivery to Subscriber of the Acquired Shares pursuant to Section 2(c) below, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), in book-entry form. If this Subscription Agreement is terminated prior to the Closing or the Closing does not occur within five (5) business days following the Scheduled Closing Date and the Purchase Price has

2

already been sent by Subscriber to the escrow account, then immediately upon such termination or failure of closing, the Company will instruct the escrow agent to promptly (but in no event longer than one (1) business day thereafter) return such Purchase Price, without any deduction for or on account of any tax, withholding, charges, or set-off, to Subscriber by wire transfer in immediately available funds to the account specified by Subscriber. For purposes of this Subscription Agreement, “business day” shall mean a day other than a Saturday, Sunday or other day on which commercial banks in New York, New York are authorized or required by law to close.

Additionally, for avoidance of doubt, any amendment or modification of any IIAC SEC Document (or any agreement filed as an exhibit to any IIAC SEC Document) from its initial filing date in a subsequent filing as required in connection with any guidance of the SEC following the date of this Agreement shall not be deemed to constitute a breach of this Section 4(k).

Morgan Securities PLC and/or UBS Securities LLC (collectively, the “Placement Agents”) or any of their affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing concerning the Company or the Acquired Shares or the offer and sale of the Acquired Shares.

(h)    Subscriber became aware of this offering of the Acquired Shares solely by means of direct contact between Subscriber and the Company, IIAC, the Placement Agents or a representative of the Company, IIAC or the Placement Agents, and the Acquired Shares were offered to Subscriber solely by direct contact between Subscriber and the Company or the Placement Agents. Subscriber did not become aware of this offering of the Acquired Shares, nor were the Acquired Shares offered to Subscriber, by any other means and none of the Company, the Placement Agents, IIAC or their respective representatives or any person acting on behalf of any of them acted as investment advisor, broker or dealer to Subscriber. Subscriber acknowledges that the Company represents and warrants that the Acquired Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

(i)    Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Acquired Shares, including but not limited to those set forth in the Company’s and IIAC’s filings with the SEC. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Acquired Shares, and Subscriber has sought such accounting, legal and tax advice as Subscriber has considered necessary to make an informed investment decision. Subscriber has made its own assessment and has satisfied itself concerning relevant tax and other economic considerations relative to its purchase of the Acquired Shares. Subscriber will not look to the Placement Agents or any of their affiliates or representatives for all or part of any such loss or losses Subscriber may suffer.

(j)    Subscriber acknowledges and agrees that neither the Placement Agents nor any affiliate or representative of the Placement Agents has provided Subscriber with any information or advice with respect to the Acquired Shares nor is such information or advice necessary or desired. Subscriber acknowledges that the Placement Agents and their affiliates and representatives (i) have not made any representation as to the Company or the quality of the Acquired Shares, (ii) may have acquired non-public information with respect to the Company which Subscriber agrees need not be provided to it, (iii) have made no independent investigation with respect to the Company or the Acquired Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Company, (iv) have not acted as Subscriber’s financial advisor or fiduciary in connection with the issue and purchase of the Acquired Shares and (v) have not prepared a disclosure or offering document in connection with the offer and sale of the Acquired Shares. Subscriber further acknowledges that the Placement Agents may have existing or future business relationships with IIAC and the Company, including, but not limited to, acting as financial advisors for the Transaction.

(k)    Subscriber represents and acknowledges that Subscriber, alone, or together with any professional advisor(s), has adequately analyzed and fully considered the risks of an investment in the Acquired Shares and determined that the Acquired Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

(l)    Subscriber understands and acknowledges that no federal or state agency has passed upon or endorsed the merits of the offering of the Acquired Shares or made any findings or determination as to the fairness of an investment in the Acquired Shares.

(m)    Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification List, each of which is administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) (collectively “OFAC Lists”), (ii) owned or

13

controlled by, or acting on behalf of, a person, that is named on an OFAC List, (iii) organized, incorporated, established, located, resident or born in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, the Crimea region of Ukraine, or any other country or territory embargoed or subject to substantial trade restrictions by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515 or (v) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (each, a “Prohibited Subscriber”). Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. section 5311 et seq.) (the “BSA”), as amended by the USA PATRIOT Act of 2001 (the “PATRIOT Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that, to the extent required, Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it (or its investment manager) maintains policies and procedures reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors against the OFAC Lists. Subscriber further represents and warrants that, to the extent required, it (or its investment manager) maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Acquired Shares were legally derived and were not obtained, directly or indirectly, from a Prohibited Subscriber.

(n)    Subscriber, when required to deliver payment to the Company pursuant to Section 2 above, will have sufficient funds to pay the Purchase Price and consummate the purchase of the Acquired Shares pursuant to this Subscription Agreement.

(o)    Subscriber understands that Deutsche Bank Securities Inc. and Goldman Sachs & Co. LLC will receive deferred underwriting commissions as disclosed in IIAC’s prospectus, dated November 18, 2020, upon consummation of the Transaction.

(p)    As of the date hereof, Subscriber does not have, and during the thirty (30) day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or short sale positions with respect to the securities of the Company. Notwithstanding the foregoing, nothing in this Section 5(p) (i) shall apply to any entities under common management with Subscriber (including Subscriber’s controlled affiliates and/or affiliates) from entering into any such transactions; and (ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, the representations set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Acquired Shares covered by this Agreement.

(q)    Subscriber is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) acting for the purpose of acquiring, holding, voting or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act), other than a group consisting solely of Subscriber and its affiliates.

6.    Registration Rights.

(a)    In the event that the Acquired Shares are not registered in connection with the consummation of the Transaction, the Company agrees that, as soon as practicable (but in any case no later than forty-five (45) calendar days after the Closing Date) (the “Filing Deadline”), it will file with the SEC (at its sole cost and expense) a registration statement registering the resale of the Acquired Shares (the “Registration Statement”) naming the Subscriber as a selling shareholder thereunder, and it shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as

14

practicable after the filing thereof, but no later than the earlier of (i) thirty (30) calendar days after the filing thereof (or ninety (90) calendar days after the filing thereof if the SEC notifies the Company that it will “review” the Registration Statement) and (ii) ten (10) business days after the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review (the “Effectiveness Deadline”). The Company’s obligations to include the Acquired Shares issued pursuant to this Subscription Agreement (or shares issued in exchange therefor) for resale in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of such Acquired Shares, which shall be limited to non-underwritten public offerings, as shall be reasonably requested by the Company to effect the registration of such Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling shareholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable, during any customary blackout or similar period or as permitted hereunder; provided, however, that in connection with the foregoing, Subscriber shall not be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Acquired Shares. Notwithstanding the foregoing, if the SEC prevents the Company from including any or all of the Acquired Shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the shares by the selling shareholders named therein or otherwise, such Registration Statement shall register for resale such number of Acquired Shares which is equal to the maximum number of Acquired Shares as is permitted by the SEC. In such event, the number of Acquired Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable after being permitted to register additional Acquired Shares under Rule 415 under the Securities Act, the Company shall amend the Registration Statement or file a new Registration Statement to register such Acquired Shares not included in the initial Registration Statement and shall use commercially reasonable efforts to have such amendment or Registration Statement declared effective as soon as practicable after the filing thereof. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the SEC; provided, that if the SEC requests that the Subscriber be identified as a statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw its Acquired Shares from the Registration Statement. With respect to the information to be provided by Subscriber pursuant to this Section 6(a), the Company shall request such information from Subscriber at least five (5) business days prior to the anticipated filing date of the Registration Statement and the Subscriber shall provide such requested information to the Company at least two (2) business days prior to the anticipated filing date of the Registration Statement with the SEC. For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or effect the Registration Statement as set forth above in this Section 6.

(b)    In the case of the registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. Except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the Company shall (at its own expense) use commercially reasonable efforts to cause such Registration Statement, or another shelf registration statement that includes the Acquired Shares to be sold pursuant to this Subscription Agreement, to remain effective until the earliest of (i) the third anniversary of the Closing, (ii) the date on which Subscriber ceases to hold any Acquired Shares issued pursuant to this Subscription Agreement, or (iii) on the first date on which Subscriber is able to sell all of its Acquired Shares issued pursuant to this Subscription Agreement (or shares received in exchange therefor) under Rule 144 within 90 days without the public information, volume or manner of sale limitations of such rule and without the requirement for the

15

Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). The period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”. Subscriber agrees to disclose its ownership to the Company upon reasonable request to assist it in making the determination with respect to Rule 144 described in clause (iii) above. The Company may amend the Registration Statement so as to convert the Registration Statement to a Registration Statement on Form F-3 at such time after the Company becomes eligible to use such Form F-3. During the Registration Period (or, with respect to clause (v)(2) below, for so long as the Subscriber holds the Acquired Shares), the Company shall, at its expense:

(i)    advise Subscriber as promptly as practicable and in any case within three (3) business days:

(1)    when a Registration Statement or any amendment thereto has been filed with the SEC and when such Registration Statement or any post-effective amendment thereto has become effective;

(2)    after it shall have received notice or obtained knowledge thereof, of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3)    of the receipt by the Company of any notification with respect to the suspension of the qualification of the Acquired Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4)    subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires making changes in any Registration Statement or prospectus included therein so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading;

provided that, notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events described in clauses (1) through (4) above, provide Subscriber with any material, nonpublic information regarding the Company other than to the extent that providing notice to Subscriber of the occurrence of such events may constitute material, nonpublic information regarding the Company;

(ii)    use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iii)    upon the occurrence of any event contemplated above, except for such times the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to, as soon as reasonably practicable, prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Acquired Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

16

(iv)    use its commercially reasonable efforts to cause all Acquired Shares to be listed on each securities exchange or market, if any, on which the Common Shares issued by the Company have been listed;

(v)    use its commercially reasonable efforts (1) to take all other steps necessary to effect the registration of the Acquired Shares contemplated hereby and (2) with a view to making available to Subscriber the benefits of Rule 144 or any similar rule or regulation of the SEC that may permit Subscriber to sell the Acquired Shares to the public without registration, for so long as the Subscriber holds the Acquired Shares, to (A) make and keep public information available, as those terms are understood and defined in Rule 144, (B) file all reports and other materials required to be filed by the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144, and (C) furnish to Subscriber, promptly upon request, (I) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act and (II) such other information as may reasonably be requested to enable Subscriber to sell the Subscribed Shares under Rule 144 without registration; and

(vi)    otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Subscriber, consistent with the terms of this Subscription Agreement, in connection with the registration of the Acquired Shares.

(c)    Notwithstanding anything to the contrary in this Subscription Agreement, Subscriber acknowledges and agrees that (i) the Company may suspend the use of any such Registration Statement if it determines that in order for such Registration Statement not to contain a material misstatement or omission, an amendment thereto would be needed to include information that would at that time not otherwise be required in a current or annual report under the Exchange Act; and (ii) the Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, (A) if any information (e.g., compensation data) is not readily available and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, (B) at any time the Company is required to file a post-effective amendment to the Registration Statement and the SEC has not declared such amendment effective or (C) if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”) provided, that (I) the Company shall not so delay filing or so suspend the use of the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than one hundred-twenty (120) total calendar days, in each case during any three hundred sixty (360)-day period, (II) in case of clause (i) above, the Company shall have a bona fide business purpose for not making such information public and (III) the Company shall use commercially reasonable efforts to make such Registration Statement available for the sale by Subscriber of such securities as soon as practicable thereafter. Upon receipt of any written notice from the Company of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances

17

under which they were made, in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Acquired Shares under the Registration Statement (which, for the avoidance of doubt, shall not include sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Acquired Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

(d)    Subscriber may deliver written notice (an “Opt-Out Notice”) to the Company requesting that Subscriber not receive notices from the Company otherwise required by this Section 6; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Company shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify the Company in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 6(d)) and the related suspension period remains in effect, the Company will so notify Subscriber, within two (2) business day of Subscriber’s notification to the Company, by delivering to Subscriber a copy of such previous notice of such Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability, and Subscriber shall comply with any restrictions on using such Registration Statement during such Suspension Event.

(e)    The Company shall, notwithstanding the termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), its directors, officers, partners, managers, members, investment advisers, and each person, if any, who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all out-of-pocket losses, claims, damages, liabilities, costs (including reasonable and documented external attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein or Subscriber has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder in connection with any sale pursuant to the Registration Statement; provided, however, that the indemnification contained in this Section 6(e) shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the

18

Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by Subscriber expressly for use in the Registration Statement, (B) in connection with any failure of such person, to the extent required, to deliver or cause to be delivered a prospectus made available by the Company in a timely manner or (C) in connection with any offers or sales effected by or on behalf of Subscriber in violation of Section 6(c) hereof; provided, further, however, that a Subscriber that delivers an Opt-Out Notice will not be indemnified under this Section 6(e), unless such Subscriber notifies the Company of an intended use of the Registration Statement under Section 6(d).

(f)    Subscriber shall, severally and not jointly with any Other Subscriber, indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation.

(g)    Any person or entity entitled to indemnification herein shall (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (B) unless in the reasonable judgment of legal counsel to such indemnified party a conflict of interest exists between such indemnified and indemnifying parties with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (which consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. The indemnification provided for under this Section 6 shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities.

(h)    If the indemnification provided under this Section 6 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses, then the

19

indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the Subscriber shall be limited to the net proceeds received by such Subscriber from the sale of Acquired Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses shall be deemed to include, subject to the limitations set forth in Section 6 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 6(h) from any person or entity who was not guilty of such fraudulent misrepresentation.

(i)    For purposes of this Section 6, (i) “Subscriber” shall include any person to whom the rights under this Section 6 shall have been duly assigned and (ii) “Acquired Shares” shall mean, as of any date of determination, the Acquired Shares purchased by the Subscriber pursuant to this Subscription Agreement and any other equity security issued or issuable with respect to the Acquired Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event.

(j)    The Company shall use commercially reasonable efforts, if requested by Subscriber to, within five (5) business days of such request, (i) cause the removal of restrictive legends from any Acquired Shares being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of such Acquired Shares and (ii) cause its legal counsel to deliver an opinion, if necessary, to the transfer agent in connection with the removal of such restrictive legends, in each case, upon the receipt of customary representations and other documentation from the Subscriber that is necessary to establish that restrictive legends are no longer required as reasonably requested by the Company, its counsel or the transfer agent. The Company shall be responsible for the fees of its transfer agent, its legal counsel and all DTC fees associated with such legend removal.

7.    Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with the terms therein, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) April 18, 2022 if the Closing has not occurred by such date, other than as a result of a breach of Subscriber’s obligations hereunder, or (d) if any of the conditions to Closing set forth in Section 2 of this Subscription Agreement are (i) not satisfied or waived prior to the Closing or (ii) not capable of being satisfied on the Closing and, in each case of (i) and (ii), as a result thereof, the transactions contemplated by this Subscription Agreement will not be and are not consummated at the Closing (the termination events described in clauses (a) – (d) above, collectively, the “Termination Events”); provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. The Company shall notify Subscriber in writing of the termination of the Business Combination Agreement promptly after the termination of such agreement. Upon the occurrence of any Termination Event, any monies paid by Subscriber to the Company in connection herewith shall promptly (and in any event within one (1) business day) following the Termination Event be returned to Subscriber by wire transfer of immediately available funds to the account specified by Subscriber without any deduction for or on account of any tax, withholding, charges, or set-off.

8.    Trust Account Waiver. Subscriber acknowledges that IIAC is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving the Company and one or more businesses or assets. Subscriber further acknowledges that, as described in IIAC’s prospectus relating to its initial public offering dated November 18, 2020 (the “Prospectus”), available at www.sec.gov, substantially all of IIAC’s assets consist of the cash proceeds of IIAC’s initial public offering and a private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of IIAC, its public shareholders and the underwriters of IIAC’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to IIAC to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus.

(b)    Subscriber acknowledges that the Company, IIAC, the Placement Agents (solely with respect to and as express third-party beneficiaries of, with a right to enforce as to themselves, Section 3, Section 4, Section 5, Section 9 and Section 10) and others will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement, including Schedule A hereto.

(f)    This Subscription Agreement may not be amended, modified or terminated (other than pursuant to the terms of Section 7 above) except by an instrument in writing, signed by each of the parties hereto. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties and third-party beneficiaries hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

(g)    This Subscription Agreement (including the schedule hereto) and the Redemption Offset Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.

Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation (including, without limitation, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), other than the statements, representations and warranties of the Company and IIAC expressly contained in this Subscription Agreement, in making its investment or decision to invest in the Company. Subscriber acknowledges and agrees that none of (i) any Other Subscriber pursuant to any Other Subscription Agreement (including such Other Subscriber’s respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing) or (ii) the Placement Agents, their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing, shall have any liability to Subscriber, pursuant to, arising out of or relating to this Subscription Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby, including, without limitation, with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Acquired Shares or with respect to any claim (whether in tort, contract or otherwise) for breach of this Subscription Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or

25

omissions with respect to any information or materials of any kind furnished by the Company, IIAC, the Placement Agents or any Non-Party Affiliate concerning the Company, IIAC, the Placement Agents, any of their controlled affiliates, this Subscription Agreement or the transactions contemplated hereby.

12.    Separate Obligations. For ease of administration, this single Subscription Agreement is being executed so as to enable each Subscriber identified on the signature page to enter into a Subscription Agreement, severally, but not jointly. The parties agree that (i) each Subscription Agreement shall be treated as if it were a separate agreement with respect to each Subscriber listed on the signature page, as if each Subscriber entity had executed a separate Subscription Agreement naming only itself as Subscriber, and (ii) no Subscriber listed on the signature page shall have any liability under the Subscription Agreement for the obligations of any other Subscriber so listed. For the avoidance of doubt, all obligations of the Subscriber hereunder are separate and several from the obligations of any Other Subscriber. The decision of the Subscriber to purchase the Acquired Shares pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as to the business, financial condition or results of operations of the Company, IIAC, or any of their respective subsidiaries which may have been made or given by any Other Subscriber or by any agent or employee of any Other Subscriber, and neither the Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber

26

(or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by the Subscriber or Other Subscribers pursuant hereto or thereto, shall be deemed to constitute the Subscriber and any Other Subscriber as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Subscriber and the Other Subscribers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. The Subscriber acknowledges that no Other Subscriber has acted as agent for the Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of the Subscriber in connection with monitoring its investment in the Acquired Shares or enforcing its rights under this Subscription Agreement. The Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber to be joined as an additional party in any proceeding for such purpose.

For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”)); or (ii) a customer within the meaning of Directive 2016/97/EU, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the securities or otherwise making them available to retail investors in the EEA or the United Kingdom has been prepared and therefore offering or selling the securities or otherwise making them available to any retail investor in the EEA or the United Kingdom may be unlawful under the PRIIPs Regulation. We did not receive in the United States any document related to the offer or sale of the Acquired Shares, and did not send any such document into the United States; we have not used, directly or indirectly, the mails, or a means of communication or other means or instrumentality of commerce or the facilities of a United States securities exchange in relation to the offer or sale of the Acquired Shares.

(“IIAC”), a special purpose acquisition corporation sponsored by investment subsidiaries of Investindustrial VII L.P., announced today that, following private inquiries from several investors interested in the business combination between IIAC and Zegna (the “Business Combination”), they have entered into agreements with certain large institutional and other investors for an additional PIPE facility of up to $125 million, seeking to accommodate most of the demand. Investments in the new PIPE facility would be limited to the amount of redemptions by public IIAC shareholders to limit dilution to existing investors. If redemptions exceed a specified threshold, subscribers under the new PIPE facility will acquire shares of Zegna at closing, in varying amounts pro rated to each investor’s maximum commitment depending on the level of redemptions. IIAC had raised total gross proceeds of $402.5 million in its initial public offering, as announced by IIAC on November 27, 2020. The new PIPE facility is in addition to the $250 million PIPE facility and the €184.5 million (subject to adjustment) forward purchase arrangement with an affiliate of IIAC announced on July 19, 2021.

The EGM of IIAC has been called for December 15, 2021 at 9:00 a.m. Eastern Time, to approve the Business Combination. Holders of IIAC’s Class A ordinary shares and Class B ordinary shares at the close of business on the record date of November 5, 2021 are entitled to notice of and to vote at the EGM. Holders of IIAC Class A ordinary shares can validly submit their shares for redemption until 5:00 p.m. Eastern Time on December 13, 2021.

More details on the Business Combination and the resolutions to be voted upon at the EGM can be found in the definitive proxy statement filed by IIAC, available at the following link: https://www.sec.gov/Archives/edgar/data/1825042/000119312521342341/d198909ddef14a.htm.

The closing of the Business Combination, the listing of Zegna and the first day of trading on NYSE under the ticker symbol “ZGN” are expected before year end, subject to customary approvals and conditions, including the IIAC’s shareholders’ approval of the Business Combination at the EGM.

This communication contains forward-looking statements within the meaning of section 27A of the Securities Act and Section 21E of the Exchange Act that are based on beliefs and assumptions and on information currently available to Zegna and IIAC. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including strategies or plans as they relate to the Business Combination, are also forward-looking statements. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although each of Zegna and IIAC believes that it has a reasonable basis for each forward-looking statement contained in this communication, each of Zegna and IIAC caution you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, risks and uncertainties are described in the Registration Statemnt and definitive proxy statement/prospectus relating to the Business Combination filed by Zegna with the SEC and other documents filed by Zegna and IIAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Most of these factors are outside Zegna’s and IIAC’s control and are difficult to predict. Forward-looking statements in this communication include, but are not limited to, statements regarding the Business Combination, including the timing and structure of the transaction, the proceeds of the transaction and the benefits of the Business Combination. Neither Zegna nor IIAC can assure you that the forward-looking statements in this communication will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the risk that the Business Combination may not be completed in a timely manner or at all, the ability to complete the Business Combination due to the failure to obtain approval from IIAC’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to the termination of the Business Combination Agreement or the termination of any PIPE investor’s subscription agreement, the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination, the ability to

recognize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the Business Combination, the amount of redemption requests made by IIAC’s public shareholders, costs related to the Business Combination, the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination, general economic, political and business conditions, applicable taxes, inflation, interest rates and the regulatory environment, the risk that Zegna may not be able to maintain the recognition, integrity or reputation of its brands or is unable to anticipate trends and identify and respond to new and changing consumer preferences, Zegna’s failure to implement its strategy, any disruption in Zegna’s manufacturing and logistics facilities, fluctuations in the price or quality of, or disruptions in the availability of, raw materials used in Zegna’s products, Zegna’s inability to negotiate, maintain or renew its license agreements and strategic alliances, the outcome of any potential litigation, government or regulatory proceedings, changes in macro-economic conditions and tourist traffic and demand, Zegna’s ability to retain certain key personnel and craftsmen, any disruption in Zegna’s information technology, including as a result of cybercrimes, Zegna’s competitive position, risks related to Zegna’s management team’s limited experience in managing a public company, Zegna’s intellectual property position, including its ability to protect and maintain its intellectual property rights, fluctuations in foreign currency exchange rates that could result in currency transaction losses that negatively impact Zegna’s financial results and the anticipated transaction proceed uses and sources, the ability of the combined company to grow and manage growth profitably and retain its key employees, the inability to obtain or maintain the listing of the combined company’s securities on the New York Stock Exchange following the business combination, the impact of the global COVID-19 pandemic on any of the foregoing, and other risks and uncertainties, including those included under the heading “Risk Factors” in the Registration Statement on Form F-4 filed by Zegna with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2020 of IIAC and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by Zegna, IIAC, their respective directors, officers or employees or any other person that Zegna and IIAC will achieve their objectives and plans in any specified time frame, or at all. The forward-looking statements in this communication represent the views of Zegna and IIAC as of the date of this communication. Subsequent events and developments may cause that view to change. However, while Zegna and IIAC may elect to update these forward-looking statements at some point in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of Zegna or IIAC as of any date subsequent to the date of this communication.

No Offer or Solicitation

This communication is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination and does not constitute an offer to sell or a solicitation of an offer to buy any securities of IIAC or Zegna, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction.
