**Item 1.01. Entry into a Material Definitive Agreement.**

As previously disclosed by Aimfinity Investment Corp. I ("AIMUF" or the "Company") in its Current Report on Form 8-K filed on October 16, 2023, on October 13, 2023, the Company entered into that certain Agreement and Plan of Merger (as may be amended, supplemented or otherwise modified from time to time, the "Merger Agreement"), with Docter Inc., a Delaware corporation ("Docter"), Aimfinity Investment Merger Sub I, a Cayman Islands exempted company and wholly-owned subsidiary of AIMUF (the "Purchaser"), and Aimfinity Investment Merger Sub II, Inc., a Delaware corporation and wholly-owned subsidiary of Purchaser ("Merger Sub"), pursuant to which AIMUF will complete a business combination (the "Business Combination") with Docter that involves a reincorporation merger and an acquisition merger. The Purchaser shall survive the Business Combination and be referred to as "PubCo" after the Business Combination.

Under Section 9.6 of the Merger Agreement, the parties agreed to use reasonable commercial effort to obtain transaction financing to support the Business Combination.

 

On July 25, 2025, Horn Enterprise Co., Ltd., a Taiwanese company and the wholly-owned subsidiary of Docter ("Horn"), issued a non-interest bearing promissory note (each, a "Horn Note," collectively, the "Horn Notes") to each of Ji-Jung Chou, a Taiwanese national, and Shi-Jyun Lan, a Taiwanese national (each, an "Investor," collectively, the "Investors"), respectively. Each Horn Note has a principal amount of $45,000,000 New Taiwanese Dollar (or approximately $1,536,413) Horn borrowed from each Investor. In connection with the issuance of the Horn Notes, on the same day, the Purchaser, Horn and each of the Investors entered into a stock purchase agreement (each, a "SPA", collectively, the "SPAs"), pursuant to each of which, each Investor agreed to purchase from Purchaser and Purchaser agreed to sell to each Investor such number of ordinary shares of the Purchaser, par value $0.0001 per share (the "Purchaser Shares"), equal to (i) the aggregated outstanding principal amount of the Horn Notes divided by (ii) $10.00, immediately prior to or upon the Closing (as defined in the Merger Agreement) of the Business Combination. The Investors shall accept the Purchaser Shares as satisfaction of the payment of the Horn Notes in lieu of repayment of the Horn Notes to Horn in cash. The Purchaser has also granted customary demand and piggy-back registration rights to each of the Investors. The Purchaser Shares will be issued pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act.

The foregoing description of the SPAs and the Horn Notes does not purport to be complete and is qualified in its entirety by reference to the full text of each of the SPAs and the Horn Notes, which are filed as Exhibits 10.1 through 10.4 hereto and are incorporated herein by reference.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant** 

***SPAs and Horn Notes***

 

The disclosures set forth above in Item 1.01 of this Current Report on Form 8-K are incorporated by reference herein.

***July Monthly Extension***

On January 9, 2025, the Company held an extraordinary general meeting, where the shareholders of the Company approved to amend the Company's amended and restated memorandum and articles of associations (the "Charter") to allow the Company until January 28, 2025 to consummate an initial business combination and may elect to extend the period to consummate an initial business combination up to nine times, each by an additional one-month period (each, a "Monthly Extension"), for a total of up to nine months to October 28, 2025, by depositing into the Company's trust account (the "Trust Account") an amount equal to $0.05 for each public share for each one-month extension.

On July 28, 2025, the Company issued an unsecured promissory note of $55,824 (the "Extension Note") to I-Fa Chang, a member and manager of Aimfinity Investment LLC, the sponsor of the Company (the "Sponsor"), as the Sponsor's designee, to evidence the payments made for $55,824 (the "New Monthly Extension Payment") to be deposited into the Trust Account for the public shareholders, which enables the Company to extend the period of time it has to consummate the Business Combination by one month from July 28, 2025 to August 28, 2025 (the "New Extension"). The New Extension is the seventh of nine possible Monthly Extensions permitted under the Charter.

Pursuant to the Extension Note, and a certain exchange agreement, dated April 8, 2025, by and among the Company, Mr. Chang and certain other parties to the Merger Agreement, upon the closing of the Business Combination by and between the Company and Docter, the balance of the Extension Note, unless repaid in part or in full, will automatically be exchanged for such number of PubCo ordinary shares at a conversion price of $10.00 per share. The Extension Note was issued pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act").

A copy of the Extension Note is filed as Exhibit 10.5 to this Current Report on Form 8-K and is incorporated herein by reference. The disclosures set forth in this Item 2.03 are intended to be summaries only and are qualified in their entirety by reference to the Note.

**Item 3.02. Unregistered Sales of Equity Securities.**

The disclosures set forth above in Items 1.01 and 2.03 of this Current Report on Form 8-K are incorporated by reference herein.

**Item 7.01 Regulation FD Disclosure.**

On July 28, 2025, the Company issued a press release (the "Press Release") announcing the New Extension. A copy of the Press Release is furnished as Exhibit 99.1 hereto. The information in this Item 7.01 and Exhibit 99.1 furnished hereto shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such filing.

**Item 8.01. Other Events**

The registration statement/proxy statement in Form F-4 in connection with the Business Combination (File Number 333-284658, the "Registration Statement") contains the unaudited pro forma condensed combined balance sheet as of June 30, 2024 which gives pro forma effect to the Business Combination as if it had been consummated as of that date. The basis of such pro forma presentation assumes different scenarios of the redemption requests by the Company's public shareholders.

On March 27, 2025, the Company held an extraordinary general meeting of the shareholders (the "EGM") in connection with the Business Combination at which the shareholders of the Company approved the business Combination.

In connection with the EGM, holders of 1,072,957 shares of Class A ordinary shares of the Company exercised redemption rights. Thus, the updated unaudited pro forma condensed combined financial information included in this report is presented based on the actual redemption requests by the Company's public shareholders and gives consideration of:

● The Purchase Agreement as previously disclosed in the Current Report on Form 8-K filed on May 30, 2025;

● The conversion of the outstanding extension loan and working capital loan of the Company as previously disclosed in the Current Report on Form 8-K filed on April 9, 2025;

● The conversion of the outstanding promissory notes of Docter as previously disclosed in the Current Report on Form 8-K filed on April 9, 2025;

● The Discharge Agreements as previously disclosed in the Current Report on Form 8-K filed on June 18, 2025;

● The SPA and Notes as disclosed in Item 1.01 of this Current Report on Form 8-K; and

● The estimated monthly burn rate of Docter for the 12-month period from July 1, 2024 to June 30, 2025.

**UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION**

**Introduction**

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X, as amended by the final rule, Release No. 33-10786, *Amendments to Financial Disclosures about Acquired and Disposed Businesses*. Release No. 33-10786 replaced the previous pro forma adjustment criteria with simplified requirements to depict the accounting for the Transactions ("Transaction Accounting Adjustments") and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur ("Management's Adjustments"). Management has elected not to present Management's Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company reflecting the Transactions.

The unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are not necessarily indicative of what the actual results of operations and financial position would have been had the Transactions taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the combined company.

The unaudited pro forma condensed combined balance sheet as of June 30, 2024 has been prepared using, and should be read in conjunction with, the following:

● AIMUF's unaudited consolidated balance sheet as of June 30, 2024 and the related notes included elsewhere in the Company's Quarterly Report on Form 10-Q filed on August 13, 2024, through which we derived AIMUF's unaudited consolidated balance sheet as of June 30, 2024; and

● Docter's unaudited condensed consolidated balance sheet as of June 30, 2024 and the related notes included elsewhere in the Company's proxy statements on Form DEFM14A filed on March 6, 2025.

The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2024, and for the year ended December 31, 2023 has been prepared using, and should be read in conjunction with, the following:

● AIMUF's unaudited consolidated statement of operations for the six months ended June 30, 2024 and the related notes included elsewhere in the Company's Quarterly Report on Form 10-Q filed on August 13, 2024, through which we derived AIMUF's unaudited consolidated statement of operations for the six months ended June 30, 2024; and

● Docter's unaudited condensed consolidated statement of operations for the six months ended June 30, 2024 and the related notes included elsewhere in the Company's proxy statements on Form DEFM14A filed on March 6, 2025.

● AIMUF's consolidated statement of operations for the year ended December 31, 2023 and the related notes included elsewhere in the Company's Annual Report on Form 10-K filed on April 12, 2024; and

● Docter's consolidated statement of operations for the year ended December 31, 2023 and the related notes included elsewhere in the Company's proxy statements on Form DEFM14A filed on March 6, 2025.

**Description of the Business Combination**

On October 13, 2023, AIMUF, PubCo, Merger Sub, and Docter entered into the Merger Agreement, pursuant to which among other things, AIMUF will merge with and into PubCo, with PubCo as the surviving entity (the "Reincorporation Merger"); one business day after the Reincorporation Merger, Merger Sub will be merged with and into Docter, resulting in Docter being a wholly owned subsidiary of PubCo. Upon consummation of the Business Combination, PubCo shall be renamed as "Inkwater Holding Inc."

**Accounting for the Business Combination**

The Business Combination will be accounted for as a "reverse recapitalization" in accordance with ASC 805-10-55-12 through 55-15. Under this method of accounting, AIMUF will be treated as the "acquired" company for financial reporting purposes. This determination is primarily based on the fact that subsequent to the Business Combination, Docter's stockholders are expected to have a majority of the voting power of the Combined Company, Docter will comprise all of the ongoing operations of the Combined Company. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Docter issuing shares for the net assets of AIMUF, accompanied by a recapitalization. The net assets of AIMUF will be stated at historical costs. No goodwill or other intangible assets will be recorded. Operations prior to the Business Combination will be those of Docter.

**Basis of Pro Forma Presentation**

The unaudited pro forma combined financial information included in this Form 8-K has been prepared using actual redemption of AIMUF's public shares, assumes that: (i) no PubCo Warrants are exercised and (ii) no Earnout Shares are issued and outstanding.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination.

The following table illustrates estimated ownership levels in the Combined Company, immediately following the consummation of the Business Combination, based on actual redemption requests by the Public Shareholders and the following assumptions:

**NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS**

**Note 1 — Basis of Presentation**

The Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, AIMUF will be treated as the "acquired" company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination will be treated as the equivalent of Docter issuing shares for the net assets of AIMUF, accompanied by a recapitalization. The net assets of AIMUF will be stated at historical cost, with no goodwill or other intangible assets recorded.

The unaudited pro forma condensed combined balance sheet as of June 30, 2024 gives pro forma effect to the Business Combination as if it had been consummated on June 30, 2024. The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2024 and for year ended December 31, 2023 give pro forma effect to the Business Combination as if it had been consummated on January 1, 2023, the beginning of the earliest period presented in the unaudited pro forma condensed combined statements of operations.

The unaudited pro forma condensed combined balance sheet as of June 30, 2024 has been prepared using, and should be read in conjunction with, the following:

● AIMUF's unaudited consolidated balance sheet as of June 30, 2024 and the related notes included elsewhere in the Company's Quarterly Report on Form 10-Q filed on August 13, 2024, through which we derived AIMUF's unaudited consolidated balance sheet as of June 30, 2024; and

● Docter's unaudited condensed consolidated balance sheet as of June 30, 2024 and the related notes included elsewhere in the Company's proxy statements on Form DEFM14A filed on March 6, 2025.

● Docter's unaudited condensed consolidated statement of operations for the six months ended June 30, 2024 and the related notes included elsewhere in the Company's proxy statements on Form DEFM14A filed on March 6, 2025.

● AIMUF's consolidated statement of operations for the year ended December 31, 2023 and the related notes included elsewhere in the Company's Annual Report on Form 10-K filed on April 12, 2024; and

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The pro forma adjustments reflecting the consummation of the Business Combination are based on information available as of the date of this proxy statement/prospectus and certain assumptions and methodologies that management believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, the actual adjustments may materially differ from the pro forma adjustments. Management considers this basis of presentation to be reasonable under the circumstances.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the Business Combination taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the post-combination company. They should be read in conjunction with the historical financial statements and notes thereto of AIMUF and Docter.

The unaudited pro forma combined financial information included in this Form 8-K has been prepared using actual redemption of AIMUF's public shares, assumes that: (i) no PubCo Warrants are exercised and (ii) no Earnout Shares are issued and outstanding.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination.

The pro forma adjustments reflecting the consummation of the Business Combination are based on certain currently available information and certain assumptions and methodologies that Docter believes are reasonable under the circumstances. The unaudited condensed pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible the difference may be material. Management believe that their assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information also reflects certain risks and uncertainties related to the potential redemption into cash of AIMUF Public Shares.

**Note 2 — Accounting Policies**

Upon consummation of the Business Combination, management will perform a comprehensive review of the two entities' accounting policies. As a result of the review, management may identify differences between the accounting policies of the two entities which, when conformed, could have a material impact on the financial statements of the Post-Combination Company. Based on its initial analysis, management did not identify any differences that would have a material impact on the unaudited pro forma condensed combined financial information. As a result, the unaudited pro forma condensed combined financial information does not assume any differences in accounting policies.

**Note 3 — Adjustments to Unaudited Pro Forma Condensed Combined Financial Information**

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Business Combination and has been prepared for informational purposes only.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 "Amendments to Financial Disclosures about Acquired and Disposed Businesses." Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction ("*Transaction Accounting Adjustments"*) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (*"Management's Adjustments"*).

Represents the loss per share calculated using the historical weighted average shares outstanding, and the change in number of shares in connection with the Business Combination, assuming the shares were outstanding since the beginning of the earliest period presented in the unaudited pro forma condensed combined statement of operations. As the Business Combination and related transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted loss per share assumes that the shares issuable relating to the Business Combination have been outstanding for the entire period presented. Potential securities that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS for the six months ended June 30, 2024 and for the year ended December 31, 2023, a total of 12,221,238 shares, which include 9,346,238 PubCo Warrant shares, 225,000 shares underlying warrant (excluding working capital warrant), 150,000 shares underlying Private Placement Units issuable upon conversion of Working Capital Notes, and 2,500,000 Earnout Shares, are excluded in the diluted EPS calculation due to its anti-diluted effect.

Basic and diluted loss per share is computed by dividing pro forma net loss by the weighted average number of the AIMUF Ordinary Shares outstanding during the periods (including both Class A and Class B).

The unaudited pro forma condensed combined loss per share has been prepared assuming no redemptions and assuming maximum redemptions for the six months ended June 30, 2024, and for the year ended December 31, 2023:

Registration Rights

Section 4.01 *Demand Registration Rights*. The Company hereby agrees with the Buyer or its permitted transferees (collectively, the "Holders") that at any time after the Effective Time, upon the written notice of the Holders holding a majority of the Shares sold pursuant to this Agreement (the "Requesting Holders"), the Company shall, within forty-five (45) days of receipt of such written notice (the "Demand Notice"), file a registration statement under the Securities Act providing for the proposed resale of such Shares (the "Requested Shares"), all to the extent requisite to permit the sale or other disposition by the prospective seller or sellers of the Requested Shares; provided that the Company shall not be obligated to effect any such registration under any one of the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) After the Company has effected two (2) such registrations pursuant to this Section 4.01 and each such registration has been declared or ordered effective; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If any such Requesting Holders may dispose of shares of Registrable Securities pursuant to an effective registration statement under the Securities Act as in effect on the date hereof or any successor form under the Securities Act.

The Company shall not undertake, or be required to undertake, any action to qualify, register or list any securities on any exchange other than the exchange on which its securities are traded at the time.

In the event that updated financial statements are required to be included in such registration statement, the Company can, at its sole discretion, defer the filing date of the registration statement beyond the forty-five (45) days of receipt of the Demand Notice until ten days after the Company has filed an annual report on Form 20-F containing audited financial statements or furnished a report containing interim financial statements, as the case may be, and as may be required by SEC rules.

Under no circumstances shall the Company be obligated to effect more than one (1) registration statement pursuant to a Demand Notice in any six (6) month period under this Section 4.01 with respect to any or all Registrable Shares

The Company shall not be required to register any shares pursuant to this Section 4.01 or Section 4.02 which are not Registrable Shares. Registrable Shares shall mean and include the Shares issued as part of the transaction contemplated under this Agreement, provided, however, that the Shares will cease to be Registrable Shares when (A) they have been (i) effectively registered under the Securities Act and disposed of in accordance with the registration statement covering them or (ii) disposed of pursuant to Rule 144 under the Securities Act ("Rule 144"), (B) they are or may be freely traded without registration pursuant to Rule 144, or (C) they have been otherwise transferred and new certificates for them not bearing a restrictive legend have been issued by the Company and the Company shall not have "stop transfer" instructions against them.

Section 4.02 *"Piggyback" Registration Rights*. The Company hereby agrees with the Holders that at any time after the Effective Time, if the Company shall determine to proceed with the preparation and filing of a new registration statement under the Securities Act in connection with a proposed offer and sale of any of its securities by it or any of its security holders, (other than (a) a registration statement on Form F-4, S-8 or other limited purpose form) the Company will give written notice of its determination to all Holders. Upon the written request from any Holders (the "Requesting Piggyback Holders"), within 10 days after their receipt of any such notice from the Company, the Company will, except as herein provided, cause all of the Shares covered by such request (the "Requested Piggyback Shares") held by the Requesting Piggyback Holders to be included in such registration statement, all to the extent requisite to permit the sale or other disposition by the prospective seller or sellers of the Requested Piggyback Shares. If any registration pursuant to this Section 4.02 shall be underwritten in whole or in part in connection with an underwritten offering by the Company or its securities, the Company may require that the Requested Piggyback Shares be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. In such event, the Requesting Piggyback Holders shall, if requested by the underwriters, execute an underwriting agreement containing customary representations and warranties by selling shareholders; provided, that the representations by the Requesting Piggyback Holders shall be limited to matters relating to its ownership or the Shares being registered and related matters. If the managing underwriter of such public offering advises the Company that the inclusion of any or all of the Requested Piggyback Shares would reduce the number of shares to be offered by the Company or interfere with the successful marketing of the securities offered by the Company, the number of Requested Piggyback Shares otherwise to be included in the underwritten public offering may be reduced pro rata (by number of shares) among the Requesting Piggyback Holders and all other holders of piggyback registration rights with respect to the Company's ordinary shares who have requested inclusion of their securities or excluded in their entirety if so required by the underwriter.

For the purposes of calculating joint net worth, joint net worth can be the aggregate net worth of the investor and spouse or spousal equivalent; assets need not be held jointly to be included in the calculation. Reliance on the joint net worth standard of this paragraph does not require that the securities be purchased jointly. (PLEASE NOTE: In calculating net worth, you include all of your assets (other than your primary residence), whether liquid or illiquid, such as cash, stock, securities, personal property and real estate based on the fair market value of such property MINUS all debts and liabilities (other than indebtedness secured by your primary residence, up to the estimated fair market value of the primary residence, unless the borrowing occurs in the 60 days preceding the purchase of the Units and is not in connection with the acquisition of the primary residence. In such cases, the debt secured by the primary residence must be treated as a liability in the net worth calculation.). In the event any incremental mortgage or other indebtedness secured by your primary residence occurs in the 60 days preceding the date of the purchase of the Units, the incremental borrowing must be treated as a liability and deducted from your net worth even though the value of your primary residence will not be included as an asset. Further, the amount of any mortgage or other indebtedness secured by your primary residence that exceeds the fair market value of the residence should also be deducted from your net worth);

The Buyer understands that the Shares will be issued in book-entry form.

Section 3.07 *Risks of Investment.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Buyer acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in the Parent's and the Company's filings with the SEC. The Buyer is able to fend for itself in the transactions contemplated herein and 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 Shares, and the Buyer has sought such accounting, legal and tax advice as the Buyer has considered necessary to make an informed investment decision. Alone, or together with any professional advisor(s), the Buyer has considered the risks of an investment in the Shares and determined that the Shares are a suitable investment for the Buyer and that the Buyer is able at this time and in the foreseeable future to bear the economic risk of a total loss of the Buyer's investment in the Company, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Buyer acknowledges specifically that a possibility of total loss exists. In making its decision to purchase the Shares, the Buyer has relied solely upon independent investigation made by the Buyer and the representations and warranties of the Company and Horn set forth herein. Without limiting the generality of the foregoing, the Buyer has not relied on any projections or forecasts of future results of operations of the Company or Horn. Buyer acknowledges and agrees that Buyer had access to, and an adequate opportunity to review, financial and other information of the Company or Horn as Buyer deems necessary in order to make an investment decision with respect to the Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) The Buyer understands and agrees that no federal or state agency has passed upon or endorsed the merits of this offering of the Shares or made any findings or determination as to the fairness of this investment or the accuracy or adequacy of the information provided to the Buyer.

Section 3.08. *Anti-Money Laundering*. The operations of the Buyer, including the obligations of the Buyer pursuant to this Agreement, are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements and all other applicable U.S. and non-U.S. anti-money laundering laws and regulations, including, but not limited to, those of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the USA Patriot Act of 2001 and the applicable money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency in the United States and, if the Buyer is a resident of any country other than the United States the anti-money laundering laws of the country in which the Buyer is a resident (collectively, the "Anti-Money Laundering Laws"), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving Buyer with respect to the Anti-Money Laundering Laws is pending or, to the Buyer's knowledge, threatened and there is no basis for any such action, suit or proceeding.

Section 3.09. *Absence of Certain Relationships*. To the best of the Buyer's knowledge, none of: (i) the Buyer; (ii) any person controlling or controlled by the Buyer; (iii) any person having a beneficial interest in the Buyer; or (iv) any person for whom the Buyer is acting as agent or nominee in connection with the purchase of the Shares:

Registration Rights

Section 4.01 *Demand Registration Rights*. The Company hereby agrees with the Buyer or its permitted transferees (collectively, the "Holders") that at any time after the Effective Time, upon the written notice of the Holders holding a majority of the Shares sold pursuant to this Agreement (the "Requesting Holders"), the Company shall, within forty-five (45) days of receipt of such written notice (the "Demand Notice"), file a registration statement under the Securities Act providing for the proposed resale of such Shares (the "Requested Shares"), all to the extent requisite to permit the sale or other disposition by the prospective seller or sellers of the Requested Shares; provided that the Company shall not be obligated to effect any such registration under any one of the following conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) After the Company has effected two (2) such registrations pursuant to this Section 4.01 and each such registration has been declared or ordered effective; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If any such Requesting Holders may dispose of shares of Registrable Securities pursuant to an effective registration statement under the Securities Act as in effect on the date hereof or any successor form under the Securities Act.

The Company shall not undertake, or be required to undertake, any action to qualify, register or list any securities on any exchange other than the exchange on which its securities are traded at the time.

In the event that updated financial statements are required to be included in such registration statement, the Company can, at its sole discretion, defer the filing date of the registration statement beyond the forty-five (45) days of receipt of the Demand Notice until ten days after the Company has filed an annual report on Form 20-F containing audited financial statements or furnished a report containing interim financial statements, as the case may be, and as may be required by SEC rules.

Under no circumstances shall the Company be obligated to effect more than one (1) registration statement pursuant to a Demand Notice in any six (6) month period under this Section 4.01 with respect to any or all Registrable Shares

The Company shall not be required to register any shares pursuant to this Section 4.01 or Section 4.02 which are not Registrable Shares. Registrable Shares shall mean and include the Shares issued as part of the transaction contemplated under this Agreement, provided, however, that the Shares will cease to be Registrable Shares when (A) they have been (i) effectively registered under the Securities Act and disposed of in accordance with the registration statement covering them or (ii) disposed of pursuant to Rule 144 under the Securities Act ("Rule 144"), (B) they are or may be freely traded without registration pursuant to Rule 144, or (C) they have been otherwise transferred and new certificates for them not bearing a restrictive legend have been issued by the Company and the Company shall not have "stop transfer" instructions against them.

Section 4.02 *"Piggyback" Registration Rights*. The Company hereby agrees with the Holders that at any time after the Effective Time, if the Company shall determine to proceed with the preparation and filing of a new registration statement under the Securities Act in connection with a proposed offer and sale of any of its securities by it or any of its security holders, (other than (a) a registration statement on Form F-4, S-8 or other limited purpose form) the Company will give written notice of its determination to all Holders. Upon the written request from any Holders (the "Requesting Piggyback Holders"), within 10 days after their receipt of any such notice from the Company, the Company will, except as herein provided, cause all of the Shares covered by such request (the "Requested Piggyback Shares") held by the Requesting Piggyback Holders to be included in such registration statement, all to the extent requisite to permit the sale or other disposition by the prospective seller or sellers of the Requested Piggyback Shares. If any registration pursuant to this Section 4.02 shall be underwritten in whole or in part in connection with an underwritten offering by the Company or its securities, the Company may require that the Requested Piggyback Shares be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. In such event, the Requesting Piggyback Holders shall, if requested by the underwriters, execute an underwriting agreement containing customary representations and warranties by selling shareholders; provided, that the representations by the Requesting Piggyback Holders shall be limited to matters relating to its ownership or the Shares being registered and related matters. If the managing underwriter of such public offering advises the Company that the inclusion of any or all of the Requested Piggyback Shares would reduce the number of shares to be offered by the Company or interfere with the successful marketing of the securities offered by the Company, the number of Requested Piggyback Shares otherwise to be included in the underwritten public offering may be reduced pro rata (by number of shares) among the Requesting Piggyback Holders and all other holders of piggyback registration rights with respect to the Company's ordinary shares who have requested inclusion of their securities or excluded in their entirety if so required by the underwriter. Registration pursuant to this Section 4.02 shall not be deemed to be a demand registration as described in Section 4.01 above. The Company's obligations under this Section 4.02 shall not apply to the Shares held by a Holder after the earlier of (a) three (3) years from the date of this Agreement, (b) the date that such shares held by a Holder have been sold pursuant to an effective registration statement, and (c) such time as such shares held by a Holder are eligible for immediate resale pursuant to Rule 144.

Section 4.03 *Registration Procedures*. To the extent required by Sections 4.01 and 4.02, the Company will:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) prepare and file with the Securities and Exchange Commission (the "SEC") a registration statement with respect to such securities, and use its commercially reasonable efforts to cause such registration statement to become effective as promptly as practicable after the filing thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) prepare and file with the SEC such amendments to such registration statement and supplements to the prospectus contained therein as may be necessary to keep such registration statement effective;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) use its commercially reasonable efforts to register or qualify the securities covered by such registration statement under such state securities or blue sky laws of such jurisdictions as the Requesting Holders may reasonably request, except that the Company shall not for any purpose be required to execute a general consent to service of process or to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) notify the Requesting Holders, promptly after it shall receive notice thereof, of the time when such registration statement has become effective or a supplement to any prospectus forming a part of such registration statement has been filed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) prepare and file with the SEC, promptly upon the request of any Requesting Holders, any amendments or supplements to such registration statement or prospectus which, in the opinion of counsel for such Holders (and concurred in by counsel for the Company), is required under the Securities Act or the rules and regulations thereunder in connection with the sale or other disposition of Registrable Shares held by such Requesting Holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) prepare and promptly file with the SEC and promptly notify such Requesting Holders of the filing of such amendment or supplement to such registration statement or prospectus as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the Securities Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an 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 in which they were made, not misleading; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) advise the Requesting Holders, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the SEC suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose.

It is a condition precedent to the obligations of the Company to take any action pursuant to this Article IV that the Requesting Holders shall cooperate with the Company in providing the information necessary to effect the registration of their Registrable Shares, including completion of customary questionnaires and furnishing of information regarding the Requesting Holders, the securities of the Company held by the Requesting Holders and intended method of sale or other disposition as shall be reasonably requested in writing by the Company. Failure to do so will at minimum result in exclusion of such Holders' Registrable Shares from the registration statement.

Section 4.04 *Expenses*. To the extent required by Sections 4.01 and 4.02:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Subject to Section 4.04(b), with respect to any registration required pursuant to Sections 4.01 and 4.02 hereof, all reasonable fees, costs and expenses of and incidental to such registration, inclusion and public offering (as specified in paragraph (b) below) in connection therewith shall be borne by the Company. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration process begun pursuant to this Section 4.04 if the registration request is subsequently withdrawn at the request of the Holders or any subset thereof, unless the Holders agree that such registration constitutes the use by the Holders of one (1) demand registration pursuant to Section 4.01.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The fees, costs and expenses of registration to be borne by the Company as provided in paragraph (a) above shall include, without limitation, all registration, filing, and FINRA fees, printing expenses, fees and disbursements of counsel and accountants for the Company, and all legal fees and disbursements and other expenses of complying with state securities or blue sky laws of any jurisdictions in which the securities to be offered are to be registered and qualified (except as provided in 4.04(a) above). Fees and disbursements of counsel and accountants for the Holders and any other expenses incurred by the Holders not expressly included above, including any underwriting discounts and selling commissions or other amounts payable to underwriter(s) or broker(s) in connection with the sale or other disposition of the Holders' Shares, shall be borne by the Holders or the applicable Holders (as the case may be) on a pro rata basis.

For the purposes of calculating joint net worth, joint net worth can be the aggregate net worth of the investor and spouse or spousal equivalent; assets need not be held jointly to be included in the calculation. Reliance on the joint net worth standard of this paragraph does not require that the securities be purchased jointly. (PLEASE NOTE: In calculating net worth, you include all of your assets (other than your primary residence), whether liquid or illiquid, such as cash, stock, securities, personal property and real estate based on the fair market value of such property MINUS all debts and liabilities (other than indebtedness secured by your primary residence, up to the estimated fair market value of the primary residence, unless the borrowing occurs in the 60 days preceding the purchase of the Units and is not in connection with the acquisition of the primary residence. In such cases, the debt secured by the primary residence must be treated as a liability in the net worth calculation.). In the event any incremental mortgage or other indebtedness secured by your primary residence occurs in the 60 days preceding the date of the purchase of the Units, the incremental borrowing must be treated as a liability and deducted from your net worth even though the value of your primary residence will not be included as an asset. Further, the amount of any mortgage or other indebtedness secured by your primary residence that exceeds the fair market value of the residence should also be deducted from your net worth);

All payments on this Note shall be made by wire transfer of immediately available funds to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this note (the "**Note**").

&nbsp;&nbsp;&nbsp;&nbsp;1. **Principal.** The principal balance of this Note shall be payable by the Maker to the Payee upon the date on which the Maker consummates the business combination (a "**Business Combination**") as provided in the Agreement and Plan of Merger, dated October 13, 2023, by and among the Maker, Aimfinity Investment Merger Sub I, a Cayman Islands subsidiary of the Maker (the "**PubCo** "), Aimifnity Investment Merger Sub II, Inc., a Cayman Islands subsidiary of the PubCo (the "**Merger Sub** "), and Docter, Inc., a Delaware corporation ()"**Docter** "), or the date of expiry of the term of the Maker, whichever is earlier (such date, the "**Maturity Date** "). The principal balance may be prepaid at any time prior to the Maturity Date without penalty. Under no circumstances shall any individual, including but not limited to any officer, director, employee or stockholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;2. **Conversion Rights**. In the case that the Note remains outstanding when and if the Business Combination is consummated, the Payee shall convert this Note, in whole or in part, into ordinary shares, par value $0.0001 per share, of the PubCo (the "**PubCo Shares** "). The number of PubCo Shares to be received by the Payee in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to such Payee by (y) $10.00.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Fractional Shares**. No fractional PubCo Shares will be issued upon conversion of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Effect of Conversion**. If the Maker receives notice of the Payee's intention to convert this Note at least two business days prior to the closing of a Business Combination, this Note shall be deemed to be converted on such closing date. At its expense, the Maker will cause PubCo, upon receipt of such conversion notice, as soon as practicable after consummation of a Business Combination, issue and deliver to Payee, at Payee's address as requested by Payee in its conversion notice, a certificate or certificates for the number of PubCo Shares to which Payee is entitled upon such conversion (bearing such legends as are customary pursuant to applicable state and federal securities laws), including a check payable to Payee for any cash amounts payable as a result of any fractional PubCo Shares as described herein.

&nbsp;&nbsp;&nbsp;&nbsp;3. **Interest.** This Note does not carry any interest on the unpaid principal balance of this Note, provided, that, any overdue amounts shall accrue default interest at a rate per annum equal to the interest rate which is the prevailing short term United States Treasury Bill rate, from the date on which such payment is due until the day on which all sums due are received by the Payee.

&nbsp;&nbsp;&nbsp;&nbsp;4. **Application of Payments.** All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including but not limited to reasonable attorney's and auditor's fees and expenses, then to the payment in full of any late charges, and finally to the reduction of the unpaid principal balance of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;5. **Events of Default.** The following shall constitute an event of default (each, an "**Event of Default** "):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Failure to Make Required Payments.** Failure by the Maker to pay the principal amount due pursuant to this Note more than 5 business days of the Maturity Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Voluntary Bankruptcy, etc.** The commencement by the Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of the Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of the Maker generally to pay its debts as such debts become due, or the taking of corporate action by the Maker in furtherance of any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Involuntary Bankruptcy, etc.** The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of the Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) **Breach of Other Obligations.** The Maker fails to perform or comply with any one or more of its obligations under this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) **Cross Default.** Any present or future indebtedness of the Maker in respect of moneys borrowed or raised becomes (or becomes capable of being declared) due and payable prior to its stated maturity by reason of any event of default, or any such indebtedness is not paid when due or, as the case may be, within any applicable grace period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) **Enforcement Proceedings.** A distress, attachment, execution or other legal process is levied or enforced on or against any assets of the Maker which is not discharged or stayed within 30 days.
