**OUR COMPANY**

We are a development stage biotech company specializing in the development of innovative medical device hydrogels delivered in the form of nasal sprays, which form a thin hydrogel-based shield containment barrier in the nasal cavity that can provide a barrier against viruses and allergens from contacting the nasal epithelial tissue. Our proprietary Capture and Contain™, or C&C, hydrogel technology, comprised of a mixture of naturally occurring building blocks, is delivered in the form of nasal sprays, and potentially functions as a "biological mask" with a thin shield containment barrier in the nasal cavity. We are further developing certain aspects of our proprietary C&C hydrogel technology such as the bioadhesion and prolonged retention at the nasal deposition site for intranasal delivery of drugs. We refer to our separate platform technology that is focused on nasal delivery of active pharmaceutical ingredients, or APIs, as Trap and Target™, or T&T.

***Our Product Candidates***

Our nasal hydrogels have been designed to serve as a non-invasive and fast-acting system. The hydrogels are formulated as an innovative mixture of mucoadhesive polymers <u>(</u>e.g., sodium alginate<u>)</u> which are Generally Recognized as Safe, or GRAS, by the Federal Drug Administration, or the FDA. Our mucoadhesive polymers derived from seaweed polysaccharides possess promising features as they are renewable, biodegradable, biocompatible, and environment friendly. The formulated hydrogel is sprayed into the nose to create a physical barrier with long-lasting adhesion to the mucosal membranes. Our polymers have an atomic mass much higher than the upper cell penetration limit, the polymers will simply lay on top of the cells and act as a physical barrier to viruses and allergens from contacting the nasal epithelial tissue, as opposed to penetrating the cells and causing a chemical reaction. Therefore, the C&C product candidates are not expected to be considered as drugs by the FDA but as medical devices.

Our leading technologies are C&C and T&T. The C&C provides a barrier against a wide range of allergen particulates and viruses.

***PL-14 – Nasal Allergies Blocker***

 ****

**●** We expect our PL-14 product candidate to be regulated as a Class II medical device by the FDA under its 510(k) pathway.

**●** Our PL-14 product candidate is scheduled to initiate preclinical safety trials in the fourth quarter of 2025. In addition, we have structured our clinical strategy for the PL-14 product candidate, our proprietary intranasal allergy blocker designed to treat seasonal allergic rhinitis, which includes a clinical study to evaluate the efficacy and safety of PL-14 under natural allergen exposure conditions during peak allergy seasons, a human factors study to assess usability and patient acceptance, a dedicated study evaluating nasal residence time and preparation for a pre-submission meeting with the FDA. We expect the clinical trials on our PL-14 product candidate to commence between the second quarter of 2026 and third quarter of 2026, following which we plan to submit a 510(k) application for FDA clearance.

**●** For our PL-14 product candidate, we will pursue the 510(k) pathway which requires a manufacturer to demonstrate substantial equivalence to an FDA-cleared device (i.e., predicate device) to a subject device (i.e., our product candidate). This process for clearing our device with the FDA entails performing a medical device analysis of the product candidates (e.g., PL-14 product candidate) description, operational principle, potential accessories and proposed intended use, for the purpose of identifying a predicate device that has already been cleared by the FDA. Through this review, we found three possible predicate devices for establishing substantial equivalence, Alzair, Nasalease and Bentrio. There is no guarantee that PL-14 product candidate will advance in the FDA 510(k) process at the same rate as the aforementioned predicate devices or will reach commercialization.

**●** The estimated timeline for obtaining 510(k) clearance for our PL-14 product candidate is based on the estimated time needed for the following activities: (i) GMP manufacturing of our clinical trial materials, which usually requires 9-12 months; (ii) Biocompatibility preclinical studies, which usually requires 3-6 months (although these studies may be performed concurrently with the GMP manufacturing mentioned above); (iii) Clinical trials, which usually requires 6-12 months; and (iv) FDA submission and clearance, which usually requires 3-12 months. Regarding FDA submission and clearance, generally 510(k) applicants can expect submission acceptance review decisions within 15 calendar days, substantive review decisions within 60 days, and final decisions within 90 days. In the case of our predicate devices for our PL-14 product candidate, Alzair, Nasalese and Bentrio, the FDA submission and clearance process took 86 and 140 days, respectively.

***PL-15 – COVID-19 and PL-1*6 *– Influenza Blockers***

 ****

**●** We expect our PL-15 and PL-16 product candidates, which provide a barrier against COVID-19 and influenza from contacting the nasal epithelial tissue, respectively, to be regulated as a Class II medical device under a De Novo Classification request. For the clinical studies planned for PL-15 and PL-16 which will include human subjects; the Investigational Device Exemptions regulation describes three types of device studies: significant risk, nonsignificant risk, and exempt studies. During the second half of 2025, the company intends to schedule a pre-submission meeting with the FDA to determine the IDE regulation type of device studies for PL-15 and PL-16. Our proposed 12-month interval from the scheduled FDA pre-sub meeting to the planned IDE clinical trial initiation should provide ample time to fulfill the necessary tasks for the IDE filing, such as 1) reporting previous studies to support the IDE, 2) preparing IDE required design and manufacturing control documentation, 3) conducting bench and biocompatibility tests to support safety of the device prior to starting the a human study, and 4) obtaining clinical protocol and ethics committee approvals as well as FDA IDE approval to start the clinical trial. Once IDE has been initiated, Polyrizon will comply with FDA Guidance "Changes or Modifications During the Conduct of a Clinical Investigation", 2001.

**●** Our PL-15 product candidate is scheduled to initiate preclinical safety trials in the fourth quarter of 2025, and we intend to initiate feasibility clinical trials in the third quarter of 2027 and pivotal clinical trials in the second quarter of 2028. Following these trials, we plan to submit De Novo Classification requests for each product candidate. Our PL-16 product candidate is scheduled to initiate preclinical safety trials in the fourth quarter of 2025, and we intend to initiate feasibility clinical trials in the first quarter of 2027 and pivotal clinical trials in the third quarter of 2027. Following these trials, we plan to submit De Novo Classification requests for each product candidate.

**●** Upon a review similar to the one performed for our PL-14 product candidate, we found that there were no potential predicate devices in the FDA's database matching the proposed intended uses of our PL-15 and PL-16 product candidates. Because of this, we will pursue a De Novo Classification request for each product candidate. This pathway involves demonstrating that the product candidates provide a reasonable assurance of safety and effectiveness. We have submitted a Pre-submission package for Pl-14 and during and first half of 2026 we intend to submit a Q-submission (Pre-submission) for PL-16 product candidate and request a pre-submission meeting with FDA's CDRH to confirm the potential for this regulatory path.

**●** The estimated timeline for marketing authorization via De Novo Classification grant for our PL-15 and PL-16 product candidates is based on taking similar steps as the steps described above for obtaining 510(k) clearance for our PL-14 product candidate. We estimate a longer period of time for the entire grant process for each of these product candidates due to possibly extended clinical trials requested by the FDA and also due to a longer review timeframe.

In the event the FDA does not agree with our regulatory assessments regarding the C&C product candidates 510(k) for our PL-14 product candidate, and Class II De Novo pathway for our PL-15 and PL-16 product candidates), the FDA may require us to go through a lengthier, more rigorous examination than we had expected (such as PMA, which is the FDA process of scientific and regulatory review to evaluate the safety and effectiveness of Class III medical devices. If we are required to pursue a PMA, the introduction of our product candidates into the market could be delayed.

***Trap and Target™ Product Candidates***

 ****

In contrast to our C&C product candidates, the hydrogel in the T&T product candidates is formulated differently in order to provide for sustained release of the API. The content of the hydrogel (quantity and quality) in the T&T product candidates is formulated differently than the content of C&C product candidates, and therefore enable different functions: physical barrier for the C&C product candidates and API sustained release for the T&T product candidates. It is through these differences that we rationalize the different regulatory treatment of our C&C and T&T product candidates.

The T&T platform technology is designed to allow a long residence time and an intimate contact with the mucosal tissue for a targeted delivery of medicines. We expect that our T&T platform product candidates will be regulated as a combination-product consisting of a nasal sprayer and formulation consisting of a hydrogel and a generic API, which we intend to pursue under the FDA's 505(b)(2) pathway. In addition, we have initiated preclinical studies for intranasal administration of Naloxone and intranasal administration of benzodiazepines using our T&T platform. These studies are designed to evaluate drug loading capacity, release kinetics, nasal deposition and stability, with the aim of enhancing the bioavailability and optimizing the rapid reversal effect of Naloxone in opioid overdose and benzodiazepines effect in epileptic seizures. We initiated feasibility studies for our T&T platform product candidates, which will continue through the first quarter of 2027. Pre-clinical studies for selected indications will follow and are expected to begin in the fourth quarter of 2026. Phase I clinical trials for the leading T&T technology product candidate are planned for the second quarter of 2028. In addition, we plan to start an initial testing to explore the potential of our SCI-160 platform when combined with the T&T technology, in the second quarter of 2026.

***People***

Our leadership team has a vast industry experience. Our management team has over 15 years (on average) of experience in life science companies. Our board of directors have vast experience in the life sciences industry as well as strong financial background. We believe that the holistic knowhow of our group will strongly contribute to a successful path from clinical development, regulatory approvals and commercialization of our product candidates. In addition, our management is supported by our Scientific Advisory Board which is an advisory panel of world-renowned academics and thought leaders with expertise in drug delivery systems, chemistry and pharmaceuticals.

***Market Opportunities***

We believe that our technologies have the potential to provide solutions to a broad range of unmet needs in the healthcare market. With our C&C technology, we aim to introduce solutions to address common medical and public health challenges, such as allergic rhinitis and nasal viral infections, including COVID-19. Looking towards the future, the COVID-19 pandemic highlighted the need for action at the global level to invest in technologies, tools and solutions that will help overcome the next world health crisis. We believe our technology can play an important role in aiding nations and global organizations to combat viral outbreaks. While people across the world have become accustomed to preventative measures such as vaccination, wearing masks, keeping social distance and maintaining proper hygiene, we believe that there is an obvious need for a broader arsenal of more technologically advanced tools to help protect people as they return to normal routine.

With our T&T technology, we aim to address challenges in the markets of: allergic and non-allergic rhinitis by local intranasal delivery of corticosteroids; for systemic delivery of central nervous system, or CNS, related drugs for the growing markets of combatting opioid overdose using intranasal naloxone, and benzodiazepines for seizure clusters.

We recently signed a non-binding letter of intent with Clearmind Medicine Inc., a biotech company specializing in psychedelic-derived therapeutics. Under this collaboration, we will leverage our proprietary T&T platform to develop an innovative intranasal formulation aimed at optimizing absorption and therapeutic efficacy of psychedelic-based treatments. The partnering company will finance the related research and development, including initial feasibility studies.

The ownership or voting of our Ordinary Shares by non-residents of Israel is not restricted in any way by our Articles or the laws of the State of Israel, except for ownership by nationals of certain countries that are, or have been, in a state of war with Israel.

***Liability to further capital calls***

Our Board of Directors may make, from time to time, such calls as it may deem fit upon shareholders with respect to any sum unpaid with respect to shares held by such shareholders which is not payable at a fixed time. Such shareholder has to pay the amount of every call so made upon him or her.

***The Powers of the Directors***

Our Board of Directors shall direct our policy and shall supervise the performance of our Chief Executive Officer and his actions. Our Board of Directors may exercise all powers that are not required under the Companies Law or under our Articles to be exercised or taken by our shareholders.

***Rights Attached to Shares***

Our Ordinary Shares shall confer upon the holders thereof:

**●** equal right to attend and to vote at all of our general meetings, whether regular or special, with each Ordinary Share entitling the holder thereof, which attend the meeting and participate at the voting, either in person or by a proxy or by a written ballot, to one vote;

**●** equal right to participate in distribution of dividends, if any, whether payable in cash or in bonus shares, in distribution of assets or in any other distribution, on a per share pro rata basis; and

**●** equal right to participate, upon our dissolution, in the distribution of our assets legally available for distribution, on a per share pro rata basis.

***Election of Directors***

Pursuant to our Articles, our directors are divided into three classes with staggered three-year terms. Each class of directors consists, as nearly as possible, of one-third of the total number of directors constituting the entire Board of Directors (other than the external directors, to the extent applicable). At each annual general meeting of our shareholders, the election or re-election of directors following the expiration of the term of office of the directors of that class of directors is for a term of office that expires on the third annual general meeting following such election or re-election, such that at each annual general meeting the term of office of only one class of directors expires. Each director will hold office until the annual general meeting of our shareholders in which his or her term expires, unless they are removed by a vote of 70%% of the total voting power of our shareholders at a general meeting of our shareholders (and provided such majority constitutes more than 50% of the Company's then issued and outstanding share capital) or upon the occurrence of certain events, in accordance with the Companies Law and our articles. External directors, if applicable, are elected for an initial term of three years, may be elected for additional terms of three years each under certain circumstances, and may be removed from office pursuant to the terms of the Companies Law.

***Annual and Special Meetings***

Under the Israeli law, we are required to hold an annual general meeting of our shareholders once every calendar year, at such time and place which shall be determined by our Board of Directors, that must be no later than 15 months after the date of the previous annual general meeting. All meetings other than the annual general meeting of shareholders are referred to as special general meetings. Our Board of Directors may call special meetings whenever it sees fit at such time and place, within or outside of Israel, as it may determine. In addition, the Companies Law provides that our Board of Directors is required to convene a special meeting upon written request of (i) any two of our directors or such number of directions equal to ¼ of the directors then at office (ii) as a company listed on an exchange in the U.S., one or more shareholders holding in the aggregate, either (a) 10% or more of our outstanding issued shares and 1% or more of our outstanding voting power or (b) 10% or more of our outstanding voting power.

Subject to the provisions of the Companies Law and the regulations promulgated thereunder, shareholders entitled to participate and vote at general meetings are the shareholders of record on a date to be decided by the Board of Directors, which may be between four and sixty days prior to the date of the meeting. Resolutions regarding the following matters must be passed at a general meeting of our shareholders:

**●** amendments to our Articles;

**●** the exercise of our Board of Director's powers by a general meeting if our Board of Directors is unable to exercise its powers and the exercise of any of its powers is required for our proper management;

**●** appointment or termination of our auditors;

**●** appointment of directors, including external directors;

**●** approval of acts and transactions requiring general meeting approval pursuant to the provisions of the Companies Law (mainly certain related party transactions) and any other applicable law;

**●** increases or reductions of our authorized share capital;

**●** a merger (as such term is defined in the Companies Law); and

**●** a dissolution of the company by its shareholders (as such term is defined in the Company's Law).

***Notices***

 ****

The Companies Law and our Articles require that a notice of any annual or special shareholders meeting be published in at least two widely circulated newspapers, in addition to the company's internet website, at least 21 days prior to the meeting, and if the agenda of the meeting includes the appointment or removal of directors, the approval of transactions with office holders or interested or related parties, approval of the company's general manager to serve as the chairman of the board of directors or an approval of a merger, notice must be provided at least 35 days prior to the meeting.

***Quorum***

As permitted under the Companies Law, the quorum required for our general meetings consists of at least two shareholders present in person, by proxy, written ballot or voting by means of electronic voting system, who hold or represent between them at least 25% of the total outstanding voting rights. If within half an hour of the time set forth for the general meeting a quorum is not present, the general meeting shall stand adjourned the same day of the following week, at the same hour and in the same place, or to such other date, time and place as prescribed in the notice to the shareholders and in such adjourned meeting, if no quorum is present within half an hour of the time arranged, any number of shareholders participating in the meeting, shall constitute a quorum.

***Vote Requirements***

Our Articles provide that all resolutions of our shareholders require a simple majority vote, unless otherwise required under the Companies Law or our Articles. A shareholder may vote in a general meeting in person, by proxy, by a written ballot. Under the Companies Law, each of (i) the approval of an extraordinary transaction with a controlling shareholder and (ii) the terms of employment or other engagement of the controlling shareholder of the company or such controlling shareholder's relative (even if not extraordinary) requires a special majority approval in accordance with the Companies Law. Another exception to the simple majority vote requirement is a resolution for the voluntary winding up, or an approval of a scheme of arrangement or reorganization, of the company pursuant to Section 350 of the Companies Law, which requires the approval of the majority of the shareholders voting their shares, other than abstainees, holding at least 75% of the voting rights represented at the meeting, in person, by proxy or by voting deed and voting on the resolution.

***Modification of class rights***

Unless otherwise provided by the Articles or the Companies Law, the rights attached to any class of shares, may be modified or cancelled by the Company by a resolution of the general meeting of the holders of all shares as one class, without any required separate resolution of any class of shares.

The enlargement of an existing class of shares or the issuance of additional shares thereof, shall not be deemed to modify the rights attached to the previously issued shares of such class or of any other class, unless otherwise provided by the terms of the shares.

***Dividend and liquidation rights***

We may declare a dividend to be paid to the holders of our Ordinary Shares in proportion to their respective shareholdings. Under the Companies Law, dividend distributions are determined by the Board of Directors and do not require the approval of the shareholders of a company unless the company's Articles provide otherwise. Our Articles do not require shareholder approval of a dividend distribution and provide that dividend distributions may be determined by our Board of Directors.

Pursuant to the Companies Law, the distribution amount is limited to the greater of retained earnings or earnings generated over the previous two years, according to our then last reviewed or audited consolidated financial statements, provided that the date of the financial statements is not more than six months prior to the date of the distribution, or we may distribute dividends that do not meet such criteria only with court approval; as a company listed on an exchange outside of Israel, however, court approval is not required if the proposed distribution is in the form of an equity repurchase, provided that we notify our creditors of the proposed equity repurchase and allow such creditors an opportunity to initiate a court proceeding to review the repurchase. If within 30 days such creditors do not file an objection, then we may proceed with the repurchase without obtaining court approval. In each case, we are only permitted to distribute a dividend if our Board of Directors and the court, if applicable, determines that there is no reasonable concern that payment of the dividend will prevent us from satisfying our existing and foreseeable obligations as they become due.

In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of our Ordinary Shares in proportion to their shareholdings. This right, as well as the right to receive dividends, may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.

**Access to corporate records**

Under the Companies Law, shareholders are provided access to minutes of our general meetings, our shareholders register and principal shareholders register, our Articles, our financial statements and any document that we are required by law to file publicly with the Israeli Companies Registrar or the Israel Securities Authority. In addition, shareholders may request to be provided with any document related to an action or transaction requiring shareholder approval under the related party transaction provisions of the Companies Law. We may deny this request if we believe it has not been made in good faith or if such denial is necessary to protect our interest or protect a trade secret or patent.

**Exchange controls**

There are currently no Israeli currency control restrictions on remittances of dividends on our Ordinary Shares, proceeds from the sale of the shares or interest or other payments to non-residents of Israel, except for shareholders who are subjects of certain countries that are, or have been, in a state of war with Israel.

**Limitations on the Right to Own Securities in Our Company**

There are no limitations on the right to own our securities. In certain circumstances the Warrants being offered hereby have restrictions upon the exercise of such warrants if such exercise would result in the holders thereof owning more than 4.99% or 9.99% of our Ordinary Shares upon such exercise, as further described below.

**Acquisitions under Israeli law**

***Full tender offer***

A person wishing to acquire shares of an Israeli public company and who would as a result hold over 90% of the target company's issued and outstanding share capital is required by the Companies Law to make a tender offer to all of the company's shareholders for the purchase of all of the issued and outstanding shares of the company. A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90% of the issued and outstanding share capital of a certain class of shares is required to make a tender offer to all of the shareholders who hold shares of the relevant class for the purchase of all of the issued and outstanding shares of that class. If the shareholders who do not accept the offer hold less than 5% of the issued and outstanding share capital of the company or of the applicable class, and more than half of the shareholders who do not have a personal interest in the offer accept the offer, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a tender offer will also be accepted if the shareholders who do not accept the offer hold less than 2% of the issued and outstanding share capital of the company or of the applicable class of shares.

Upon a successful completion of such a full tender offer, any shareholder that was an offeree in such tender offer, whether such shareholder accepted the tender offer or not, may, within six months from the date of acceptance of the tender offer, petition an Israeli court to determine whether the tender offer was for less than fair value and that the fair value should be paid as determined by the court. However, under certain conditions, the offeror may include in the terms of the tender offer that an offeree who accepted the offer will not be entitled to petition the Israeli court as described above.

If a tender offer is not accepted in accordance with the requirements set forth above, the acquirer may not acquire shares of the company that will increase its holdings to more than 90% of the company's issued and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

***Special tender offer***

The Companies Law provides that an acquisition of shares of an Israeli public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of 25% or more of the voting rights in the company. This requirement does not apply if there is already another holder of at least 25% of the voting rights in the company. Alternatively, such an acquisition may be approved pursuant to a private placement approved by the company's shareholders with the purpose of approving the acquisition of 25% or more, or 45% or more of the company's voting rights. Similarly, the Companies Law provides that an acquisition of shares in a public company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of more than 45% of the voting rights in the company, if there is no other shareholder of the company who holds more than 45% of the voting rights in the company, subject to certain exceptions.

In the event that a special tender offer is made, a company's board of directors is required to express its opinion on the advisability of the offer, or shall abstain from expressing any opinion if it is unable to do so, provided that it gives the reasons for its abstention. In addition, the board of directors must disclose any personal interest each member of the board of directors has in the offer or stems therefrom.

A special tender offer must be extended to all shareholders of a company but the offeror is not required to purchase shares representing more than 5% of the voting power attached to the company's outstanding shares, regardless of how many shares are tendered by shareholders. A special tender offer may be consummated only if (i) at least 5% of the voting power attached to the company's outstanding shares will be acquired by the offeror and (ii) the number of shares tendered in the offer exceeds the number of shares whose holders objected to the offer (excluding the purchaser and its controlling shareholder, holders of 25% or more of the voting rights in the company or any person having a personal interest in the acceptance of the tender offer or any other person acting on their behalf, including relatives and entities under such person's control). If a special tender offer is accepted, then the purchaser or any person or entity controlling it or under common control with the purchaser or such controlling person or entity may not make a subsequent tender offer for the purchase of shares of the target company and may not enter into a merger with the target company for a period of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender offer.

***Merger***

The Companies Law permits merger transactions if approved by each party's board of directors and, unless certain requirements described under the Companies Law are met, by a majority vote of each party's shares, and, in the case of the target company, a majority vote of each class of its shares voted on the proposed merger at a shareholders meeting. The board of directors of a merging company is required pursuant to the Companies Law to discuss and determine whether in its opinion there exists a reasonable concern that as a result of a proposed merger, the surviving company will not be able to satisfy its obligations towards its creditors, such determination taking into account the financial status of the merging companies. If the board of directors has determined that such a concern exists, it may not approve a proposed merger.

For purposes of the shareholder vote, unless a court rules otherwise, the merger will not be deemed approved if a majority of the votes of the shares represented at the shareholders meeting that are held by parties other than the other party to the merger, or by any person (or group of persons acting in concert) who holds (or hold, as the case may be) 25% or more of the voting rights or the right to appoint 25% or more of the directors of the other party, vote against the merger. If, however, the merger involves a merger with a company's own controlling shareholder or if the controlling shareholder has a personal interest in the merger, then the merger is instead subject to the same special majority approval that governs all extraordinary transactions with controlling shareholders.

If the transaction would have been approved by the shareholders of a merging company but for the separate approval of each class or the exclusion of the votes of certain shareholders as provided above, a court may still approve the merger upon the request of holders of at least 25% of the voting rights of a company, if the court holds that the merger is fair and reasonable, taking into account the value to the parties to the merger and the consideration offered to the shareholders of the company.

Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable concern that, as a result of the merger, the surviving company will be unable to satisfy the obligations of the merging entities, and may further give instructions to secure the rights of creditors.

In addition, a merger may not be consummated unless at least 50 days have passed from the date on which a proposal for approval of the merger was filed by each party with the Israeli Registrar of Companies and at least 30 days have passed from the date on which the merger was approved by the shareholders of each party.

**Exclusive Forum**

 ****

Our Articles provide that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Our Articles also provide that unless we consent in writing to the selection of an alternative forum, the competent courts in Tel Aviv, Israel shall be the exclusive forum for any derivative action or proceeding brought on behalf of the Company, any action asserting a breach of a fiduciary duty owed by any of our directors, officers or other employees to the Company or our shareholders or any action asserting a claim arising pursuant to any provision of the Companies Law or the Israeli Securities Law, 5728-1968.

**Borrowing powers**

Pursuant to the Companies Law and our Articles, our Board of Directors may exercise all powers and take all actions that are not required under law or under our Articles to be exercised or taken by a certain organ of the Company, including the power to borrow money for company purposes.

**Changes in Capital**

Our Articles enable us to increase or reduce our share capital. Any such changes are subject to the provisions of the Companies Law and must be approved by a resolution duly adopted by our shareholders at a general meeting. In addition, transactions that have the effect of reducing capital, such as the declaration and payment of dividends in the absence of sufficient retained earnings or profits, require the approval of both our Board of Directors and an Israeli court.

**Transfer agent and registrar**

Our transfer agent and registrar is Vstock Transfer LLC, or Vstock. Vstock's address is 18 Lafayette Place, Woodmere, New York 11598 and its telephone number is (212) 828-8436.

**DESCRIPTION OF WARRANTS**

We may issue and offer warrants under the material terms and conditions described in this prospectus and any accompanying prospectus supplement. The accompanying prospectus supplement may add, update or change the terms and conditions of the warrants as described in this prospectus.

We may issue warrants to purchase our Ordinary Shares. Warrants may be issued independently or together with any securities and may be attached to or separate from those securities. The warrants may be issued under warrant or subscription agreements to be entered into between us and a bank or trust company, as warrant agent, all of which will be described in the prospectus supplement relating to the warrants we are offering. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The particular terms of the warrants, the warrant or subscription agreements relating to the warrants and the warrant certificates representing the warrants will be described in the applicable prospectus supplement, including some or all of the following:

● the title of such warrants;

● the aggregate number of such warrants;

● the price or prices at which such warrants will be issued and exercised;

● the currency or currencies in which the price of such warrants will be payable;

● the securities purchasable upon exercise of such warrants;

● the date on which the right to exercise such warrants shall commence and the date on which such right shall expire;

● if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;

Holders of warrants will not be entitled, solely by virtue of being holders, to vote, to consent, to receive dividends, to receive notice as shareholders with respect to any meeting of shareholders for the election of directors or any other matters, or to exercise any rights whatsoever as a holder of the equity securities purchasable upon exercise of the warrants.

The description in the applicable prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement and warrant certificate, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of the applicable warrant agreement if we offer warrants, see "Where You Can Find Additional Information" beginning on page 21 and "Incorporation of Certain Information by Reference" beginning on page 20. We urge you to read any applicable prospectus supplement and the applicable warrant agreement and form of warrant certificate in their entirety.

**DESCRIPTION OF UNITS**

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement will describe:

● the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

● the material terms of a unit agreement under which the units will be issued;

● any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

● whether the units will be issued in fully registered or global form.

The applicable prospectus supplement will describe the terms of any units. The preceding description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. For more information on how you can obtain copies of the applicable unit agreement if we offer units, see "Where You Can Find Additional Information" beginning on page 21 and "Incorporation of Certain Information by Reference" beginning on page 20. We urge you to read the applicable unit agreement and any applicable prospectus supplement in their entirety.

**PLAN OF DISTRIBUTION**

The securities being offered by this prospectus may be sold:

● through agents;

● to or through one or more underwriters on a firm commitment or agency basis;

● through put or call option transactions relating to the securities;

● to or through dealers, who may act as agents or principals, including a block trade (which may involve crosses) in which a broker or dealer so engaged will attempt to sell as agent but may position and resell a portion of the block as principal to facilitate the transaction;

● through privately negotiated transactions;

● purchases by a broker or dealer as principal and resale by such broker or dealer for its own account pursuant to this prospectus;

● directly to purchasers, including our affiliates, through a specific bidding or auction process, on a negotiated basis or otherwise; to or through one or more underwriters on a firm commitment or best efforts basis;

● exchange distributions and/or secondary distributions;

● ordinary brokerage transactions and transactions in which the broker solicits purchasers;

● in an "at the market offering", within the meaning of Rule 415(a)(4) of the Securities Act into an existing trading market, on an exchange or otherwise;

● transactions not involving market makers or established trading markets, including direct sales or privately negotiated transactions;

● transactions in options, swaps or other derivatives that may or may not be listed on an exchange;

● through any other method permitted pursuant to applicable law; or

● through a combination of any such methods of sale.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents, any discounts, commissions, concessions and other items constituting compensation from us and any discounts, commissions or concessions allowed or re-allowed or paid to dealers. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with.

The distribution of securities may be effected from time to time in one or more transactions, including block transactions and transactions on the Nasdaq Capital Market or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. Any dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If any such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

Agents may from time to time solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities.

To the extent that we make sales to or through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will sell any of our listed securities to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell any of our listed securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement will provide that any of our listed securities which are sold will be sold at prices related to the then prevailing market prices for our listed securities. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our listed securities. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus.

If underwriters are used in a sale, securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. The prospectus and prospectus supplement will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, we or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement the name of the dealer and the terms of the transactions.

We may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Agents, underwriters and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement will describe the terms and conditions of the indemnification or contribution. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries.

Any person participating in the distribution of securities registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our securities by that person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our securities to engage in market-making activities with respect to our securities. These restrictions may affect the marketability of our securities and the ability of any person or entity to engage in market-making activities with respect to our securities.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions, penalty bids and other transactions that stabilize, maintain or otherwise affect the price of the offered securities. These activities may maintain the price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below:

● A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security.

● A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering.

● A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions.

These transactions may be effected on an exchange or automated quotation system, if the securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise.

If so indicated in the applicable prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

In addition, ordinary shares or warrants may be issued upon conversion of or in exchange for other securities.

Any underwriters to whom offered securities are sold for public offering and sale may make a market in such offered securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The offered securities may or may not be listed on a national securities exchange. No assurance can be given that there will be a market for the offered securities.

Any securities that qualify for sale pursuant to Rule 144 or Regulation S under the Securities Act may be sold under Rule 144 or Regulation S rather than pursuant to this prospectus.

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and will be identified in the applicable prospectus supplement (or a post-effective amendment).

We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus.

**WHERE YOU CAN FIND ADDITIONAL INFORMATION**

This prospectus is part of a registration statement on Form F-3 that we filed with the SEC relating to the securities offered by this prospectus, which includes additional information. You should refer to the registration statement and its exhibits for additional information. Whenever we make reference in this prospectus to any of our contracts, agreements or other documents, the references are not necessarily complete and you should refer to the exhibits attached to the registration statement for copies of the actual contract, agreements or other document.

We are subject to the informational requirements of the Exchange Act applicable to foreign private issuers. We, as a "foreign private issuer," are exempt from the rules under the Exchange Act prescribing certain disclosure and procedural requirements for proxy solicitations, and our officers, directors and principal shareholders are exempt from the reporting and "short-swing" profit recovery provisions contained in Section 16 of the Exchange Act, with respect to their purchases and sales of shares. In addition, we are not required to file annual, quarterly and current reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act.

You can review our SEC filings and the registration statement by accessing the SEC's internet site at http://www.sec.gov. We maintain a corporate website at *www.polyrizon-biotech.com*. Information contained on, or that can be accessed through, our website does not constitute a part of this prospectus. We have included our website address in this prospectus solely as an inactive textual reference.

**ENFORCEMENT OF CIVIL LIABILITIES**

We are incorporated under the laws of the State of Israel. Service of process upon us and upon our directors and officers and the Israeli experts named in this registration statement, most of whom reside outside of the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and substantially all of our directors and officers are located outside of the United States, any judgment obtained in the United States against us or any of our directors and officers may not be collectible within the United States.

We have been informed by our legal counsel in Israel, Meitar \| Law Offices, that it may be difficult to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on an alleged violation of U.S. securities laws reasoning that Israel is not the most appropriate forum to bring such a claim. In Israeli courts, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process and certain matters of procedure will also be governed by Israeli law.

We have irrevocably appointed Puglisi & Associates as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering.

Subject to specified time limitations and legal procedures, Israeli courts may enforce a U.S. judgment in a civil matter which, subject to certain exceptions, is non-appealable, including a judgment based upon the civil liability provisions of the Securities Act and the Exchange Act and including a monetary or compensatory judgment in a non-civil matter, provided that among other things:

● the judgment was rendered by a court which was, according to the laws of the state of the court, competent to render the judgment;

● the obligation imposed by the judgment is enforceable according to the rules relating to the enforceability of judgments in Israel and the substance of the judgment is not contrary to public policy; and

● the judgment is executory in the state in which it was given.

Even if these conditions are met, an Israeli court may not declare a foreign civil judgment enforceable if:

● the judgment was given in a state whose laws do not provide for the enforcement of judgments of Israeli courts (subject to exceptional cases);

● the enforcement of the judgment is likely to prejudice the sovereignty or security of the State of Israel;

● the judgment was obtained by fraud;

● the opportunity given to the defendant to bring its arguments and evidence before the court was not reasonable in the opinion of the Israeli court;

● the judgment was rendered by a court not competent to render it according to the laws of private international law as they apply in Israel;

● the judgment is contradictory to another judgment that was given in the same matter between the same parties and that is still valid; or

● at the time the action was brought in the foreign court, a lawsuit in the same matter and between the same parties was pending before a court or tribunal in Israel.

If a foreign judgment is enforced by an Israeli court, it generally will be payable in Israeli currency, which can then be converted into non- Israeli currency and transferred out of Israel. The usual practice in an action before an Israeli court to recover an amount in a non-Israeli currency is for the Israeli court to issue a judgment for the equivalent amount in Israeli currency at the rate of exchange in force on the date of the judgment, but the judgment debtor may make payment in foreign currency. Pending collection, the amount of the judgment of an Israeli court stated in Israeli currency ordinarily will be linked to the Israeli Consumer Price Index plus interest at the annual statutory rate set by Israeli regulations prevailing at the time. Judgment creditors must bear the risk of unfavorable exchange rates.

**PART II**

**INFORMATION NOT REQUIRED IN PROSPECTUS**

**Item 8. Indemnification of Directors and Officers**

The Israeli Companies Law, 5759-1999, or the Companies Law, and the Israeli Securities Law, 5728-1968, or the Securities Law, provide that a company may indemnify an office holder against the following liabilities and expenses incurred for acts performed by him or her as an office holder, either pursuant to an undertaking made in advance of an event or following an event, provided its articles of association include a provision authorizing such indemnification:

● a financial liability imposed on him or her in favor of another person by any judgment concerning an act performed in his or her capacity as an office holder, including a settlement or arbitrator's award approved by a court. However, if an undertaking to indemnify an office holder with respect to such liability is provided in advance, then such an undertaking must be limited to events which, in the opinion of the board of directors, can be foreseen based on the company's activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking shall detail the abovementioned events and amount or criteria;

● reasonable litigation expenses, including legal fees, incurred by the office holder (a) as a result of an investigation or proceeding instituted against him or her by an authority authorized to conduct such investigation or proceeding, provided that (i) no indictment was filed against such office holder as a result of such investigation or proceeding; and (ii) no financial liability, such as a criminal penalty, was imposed upon him or her as a substitute for the criminal proceeding as a result of such investigation or proceeding or, if such financial liability was imposed, it was imposed with respect to an offense that does not require proof of criminal intent; and (b) in connection with a monetary sanction;

● reasonable litigation expenses, including legal fees, incurred by the office holder or imposed by a court (i) in proceedings instituted against him or her by the company, on its behalf or by a third party, or (ii) in connection with criminal proceedings in which the office holder was acquitted, or (iii) as a result of a conviction for a crime that does not require proof of criminal intent; and

● expenses, including reasonable litigation expenses and legal fees, incurred by an office holder in relation to an administrative proceeding instituted against such office holder, or certain compensation payments made to an injured party imposed on an office holder by an administrative proceeding, pursuant to certain provisions of the Israeli Securities Law.

An Israeli company may insure an office holder against the following liabilities incurred for acts performed as an office holder if and to the extent provided in the company's articles of association:

● a breach of the duty of loyalty to the company, to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

● a breach of the duty of care to the company or to a third party, including a breach arising out of the negligent conduct of the office holder;

● a financial liability imposed on the office holder in favor of a third party;

● a financial liability imposed on the office holder in favor of a third party harmed by a breach in an administrative proceeding; and

● expenses, including reasonable litigation expenses and legal fees, incurred by the office holder as a result of an administrative proceeding instituted against him or her, pursuant to certain provisions of the Israeli Securities Law.

An Israeli company may not indemnify or insure an office holder against any of the following:

● a breach of the duty of loyalty, except to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

● a breach of duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;

● an act or omission committed with intent to derive illegal personal benefit; or

● a fine, monetary sanction or forfeit levied against the office holder.

Under the Israeli Companies Law, exculpation, indemnification and insurance of office holders must be approved by the compensation committee, the board of directors (and, with respect to directors and the chief executive officer, by the shareholders). However, under regulations promulgated under the Companies Law, the insurance of office holders shall not require shareholder approval and may be approved by only the compensation committee, if the engagement terms are determined in accordance with the company's compensation policy and that policy was approved by the shareholders by the same special majority required to approve a compensation policy, provided that the insurance policy is on market terms and the insurance policy is not likely to materially impact the company's profitability, assets or obligations.

Our Articles allow us to exculpate, indemnify and insure our office holders for any liability imposed on them as a consequence of an act (including any omission) which was performed by virtue of being an office holder. Our office holders are currently covered by a directors and officers' liability insurance policy.

We have entered into agreements with each of our directors and executive officers exculpating them in advance from liability to us for damages caused to us as a result of a breach of duty of care, and undertaking to indemnify them. This exculpation and indemnification is limited both in terms of amount and coverage and it covers certain amounts regarding administrative proceedings insurable or indemnifiable under the Companies Law and our Articles.

In the opinion of the SEC, however, indemnification of directors and office holders for liabilities arising under the Securities Act, is against public policy and therefore unenforceable.

There is no pending litigation or proceeding against any of our office holders as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification by any office holder.

\* To be filed by amendment or as an exhibit to a document incorporated by reference herein in connection with an offering of the offered securities. <br>\*\* Filed herewith.

**Item 10. Undertakings**

(a) The undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission, or Commission, pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; *provided, however*, that paragraphs (a)(1)(i), (a)(1)(ii) and a(l)(iii) do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, *provided*, that the Registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 or Rule 3-19 of this chapter if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If the Registrant is relying
 on Rule 430B:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Each prospectus filed by
 the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus
 was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Each prospectus required
 to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to
 an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a)
 of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date
 such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering
 described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an
 underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the
 registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the
 initial bona fide offering thereof. *Provided, however,* that no statement made in a registration statement or prospectus
 that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration
 statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior
 to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part
 of the registration statement or made in any such document immediately prior to such effective date; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) If the Registrant is subject
 to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than
 registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part
 of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement
 made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed
 incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a
 purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration
 statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of
 first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any preliminary prospectus
 or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any free writing prospectus
 relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The portion of any other
 free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities
 provided by or on behalf of the undersigned Registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any other communication
 that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned Registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.

(e) The undersigned Registrant hereby undertakes that for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

(f) The undersigned Registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

**SIGNATURES**

Pursuant to the requirement of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form F-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Raanana, Israel on November 7, 2025.

Re: <u>Registration Statement on Form F-3</u>

Ladies and Gentlemen:

We have acted as Israeli counsel to Polyrizon Ltd., a company organized under the laws of the State of Israel (the "**Company**"), in connection with its registration statement on Form F-3 (the "**Registration Statement**") filed with the Securities and Exchange Commission (the "**SEC**") on the date hereof under the Securities Act of 1933, as amended (the "**Securities Act**") which registers the offer, issuance and sale by the Company, from time to time, of any one or more of the following types of securities, individually or in units:

(a) ordinary shares, no par value per share ()"**Ordinary Shares**") of the Company (the "**Shares** "); and

(b) warrants to purchase Ordinary Shares (the "**Warrants**).

The Shares, Warrants and units comprising a combination of Shares and Warrants are referred herein as the "**Securities**".

This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, in connection with the filing of the Registration Statement.

In connection herewith, we have examined the originals, or photocopies or copies, certified or otherwise identified to our satisfaction, of: (i) the form of the Registration Statement, to which this opinion letter is attached as an exhibit; (ii) the amended and restated articles of association of the Company, as currently in effect (the "**Articles**"); (iii) resolutions of the board of directors of the Company (the "**Board**") by which the filing of the Registration Statement and the actions to be taken in connection therewith were approved; and (iv) such other corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company as we have deemed relevant and necessary as a basis for the opinions hereafter set forth. We have also made inquiries of such officers and representatives as we have deemed relevant and necessary as a basis for the opinions hereafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, confirmed as photostatic copies and the authenticity of the originals of such latter documents. We have also assumed the truth of all facts communicated to us by the Company and that all minutes of meetings of the Board and the shareholders of the Company that have been provided to us are true and accurate and have been properly prepared in accordance with the Articles and all applicable laws. We have assumed, in addition, that at the time of the execution and delivery of any definitive purchase, underwriting or similar agreement between the Company and any third party pursuant to which any of the Securities may be issued (a "**Securities Agreement**"), the Securities Agreement will be the valid and legally binding obligation of such third party, enforceable against such third party in accordance with its terms. We have further assumed that at the time of the issuance and sale of any of the Securities, the terms of the Securities, and their issuance and sale, will have been established so as not to violate any applicable law or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company.

Based upon and subject to the foregoing, we are of the opinion that with respect to the Shares, assuming (a) the taking of all necessary corporate action to authorize and approve the issuance of any Shares, the terms of the offering thereof and related matters (for purposes of this paragraph, the "**Authorizing Resolutions**"), (b) the effectiveness of the Registration Statement (including any post-effective amendments) shall not have been terminated or rescinded, (c) the delivery and filing of an appropriate prospectus supplement with respect to the offering of the Shares in compliance with the Securities Act and the applicable rules and regulations thereunder, (d) approval by the Board of, and entry by the Company into, and performance by the Company under, any applicable Securities Agreement, in the form filed as an exhibit to the Registration Statement, any post-effective amendment thereto or a Report of Foreign Private Issuer on Form 6-K, pursuant to which the Shares may be issued and sold, and (e) receipt by the Company of the consideration for the Shares as provided for in the Authorizing Resolutions and in accordance with the provisions of any such Securities Agreement and the applicable convertible Securities, if any, pursuant to which the Shares may be issued, such Shares, including any Ordinary Shares issued upon exercise or conversion of any Securities, will be validly issued, fully paid and non-assessable.

You have informed us that you intend to issue the Securities from time to time on a delayed or continuous basis, and this opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof. We understand that prior to issuing any Securities you will afford us an opportunity to review the corporate approval documents and operative documents pursuant to which such Securities are to be issued (including an appropriate prospectus supplement), and we will file such supplement or amendment to this opinion (if any) as we may reasonably consider necessary or appropriate by reason of the terms of such Securities.

We have further assumed that, at the time of issuance and sale of Ordinary Shares and to the extent any such issuance would exceed the maximum share capital of the Company currently authorized, the number of Ordinary Shares that the Company is authorized to issue shall have been increased in accordance with the Company's Articles such that a sufficient number of Ordinary Shares are authorized and available for issuance under the Articles.

Members of our firm are admitted to the Bar in the State of Israel, and we do not express any opinion as to the laws of any other jurisdiction. This opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm appearing under the caption "Legal Matters" and, if applicable, "Enforcement of Civil Liabilities" in the prospectus forming part of the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act, the rules and regulations of the SEC promulgated thereunder or Item 509 of the SEC's Regulation S-K under the Securities Act.

This opinion letter is rendered as of the date hereof and we disclaim any obligation to advise you of facts, circumstances, events or developments that may be brought to our attention after the effective date of the Registration Statement that may alter, affect or modify the opinions expressed herein.

Re: Polyrizon Ltd. Shelf Registration Statement on Form F-3

Ladies and Gentlemen:

We have acted as legal counsel for Polyrizon Ltd., a company organized under the Laws of the State of Israel (the "<u>Company</u>"), in connection with the preparation of a Shelf Registration Statement on Form F-3, including the prospectus constituting a part thereof (the "<u>Registration Statement</u>"), being filed by the Company with the Securities and Exchange Commission (the "<u>Commission</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), relating to the Company's offering of up to an aggregate of up to $50,000,000 of any combination of: (i) ordinary shares, with no par value, of the Company ("<u>Ordinary Shares</u>"); (ii) warrants to purchase Ordinary Shares ("<u>Warrants</u>"); (iii) purchase units consisting of Ordinary Shares and Warrants ("<u>Units</u>"); and (iv) the Ordinary Shares that may be issued upon the exercise of the Warrants or in connection with the Units, as applicable. The Ordinary Shares, Warrants and Units are referred to herein collectively as the "<u>Securities</u>." The Securities may be issued and sold or delivered from time to time as set forth in the Registration Statement, any amendment thereto, the prospectus contained therein (the "<u>Prospectus</u>") and supplements to the prospectus (the "<u>Prospectus Supplements</u>") and pursuant to Rule 415 under the Securities Act.

We are opining herein only as to the internal laws of the State of New York, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, or as to any matters of municipal law or the laws of any local agency within any jurisdiction. With respect to Israeli law, we understand that you are relying upon the opinion, dated the date hereof, of Meitar \| Law Offices, Israeli counsel to the Company, and our opinion is subject to the same assumptions, qualifications and limitations with respect to such law as contained in such opinion of Meitar \| Law Offices. We express no opinion herein regarding the validity or issuance of the Ordinary Shares, Warrants or Units, which matters are being addressed in such opinion of Meitar \| Law Offices.

The Warrants will be issued under one or more Warrant Agreements (each, a "<u>Warrant Agreement</u>"), each to be between the Company and a counterparty or counterparties identified therein (each, a "<u>Counterparty</u>"). The Units will be issued under a unit agreement (each, a "<u>Unit Agreement</u>"), each to be between the Company and a Counterparty.

In connection with our representation of the Company, and as a basis for the opinions hereinafter set forth, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. the Company's Articles of Association, as amended to the date hereof (the " <u>Charter</u> ");
and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. such other documents and records and other certificates and instruments and matters of law as we have
deemed necessary or appropriate to express the opinions set forth below, in each case subject to the assumptions, limitations and qualifications
stated herein.

In rendering the opinions set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that (i) at the time of execution, countersignature, issuance and delivery of any Warrants, each Warrant Agreement will be the valid and legally binding obligation of each Counterparty thereto and (ii) at the time of execution, countersignature, and issuance and delivery of any Units, each Unit Agreement will be the valid and legally binding obligation of each Counterparty thereto.

As to matters of fact material to this opinion, we have relied to the extent we deemed reasonably appropriate upon representations or certificates of officers or directors of the Company, without independently verifying the accuracy of such documents, records and instruments.

In connection with the issuance of Warrants, we have assumed further that (i) at the time of execution, countersignature, issuance and delivery of any Warrant Agreement, such Warrant Agreement will have been duly authorized, executed and delivered by the Company, and (ii) the execution, delivery and performance by the Company of such Warrant Agreement will not violate the laws of any jurisdiction (provided that as to the federal laws of the United States we make no such assumption).

In connection with the issuance of Units, we have assumed further that (i) at the time of execution, countersignature, issuance and delivery of any Unit Agreement, such Unit Agreement will have been duly authorized, executed and delivered by the Company, and (ii) the execution, delivery and performance by the Company of such Unit Agreement will not violate the laws of any jurisdiction (provided that as to the federal laws of the United States we make no such assumption).

We have further assumed that: (i) the Registration Statement and any amendments thereto will be effective under the Securities Act, that no stop orders will have been issued by the Commission with respect to the Registration Statement and that the Registration Statement will comply with all applicable laws at the time the Securities are offered or issued as contemplated by the Registration Statement; (ii) an appropriate Prospectus Supplement, free writing prospectus or term sheet relating to the Securities offered thereby will have been prepared and filed with the Commission in compliance with the Securities Act and will comply with all applicable laws at the time the Securities are offered or issued as contemplated by the Registration Statement; (iii) all Securities will be issued and sold in compliance with the applicable provisions of the Securities Act and the securities or blue sky laws of various states and in the manner stated in the Registration Statement and the applicable Prospectus Supplement; (iv) any purchase, underwriting or similar agreement relating to Securities being offered will have been duly authorized, executed and delivered by the Company and the other parties thereto; and (v) in connection with the issuance of any Securities, an adequate number of authorized and unissued Ordinary Shares will be available for issuance under the Charter, as then in effect.

Based upon and subject to the foregoing, and subject to the assumptions, limitations and qualifications stated herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. With respect to the Warrants, assuming (i) the taking of all necessary corporate action by the Company's
board of directors (the " <u>Board</u> ") to approve the execution and delivery of each Warrant Agreement and (ii) the due execution,
countersignature, issuance and delivery of such Warrant Agreement upon payment of the consideration therefor provided for in the applicable
definitive purchase, underwriting or similar agreement, or the Prospectus or a Prospectus Supplement approved by the Board and otherwise
in accordance with the provisions of the applicable Warrant Agreement and such agreement, such Warrants will constitute valid and legally
binding obligations of the Company enforceable against the Company in accordance with their terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. With respect to the Units, assuming (i) the taking of all necessary corporate action by the Board to approve
(x) the execution and delivery of the applicable Unit Agreements and (y) any Securities to be issued separately or as part of any such
Units, (ii) the due execution, countersignature, issuance and delivery of such Unit Agreements upon payment of the consideration therefor
provided for in the applicable definitive purchase, underwriting or similar agreement, or the Prospectus or a Prospectus Supplement approved
by the Board and otherwise in accordance with the provisions of the applicable Unit Agreements and such agreement, such Units will constitute
valid and legally binding obligations of the Company enforceable against the Company in accordance with their respective terms.

The opinions set forth above are subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws now or hereafter in effect relating to or affecting creditors' rights generally, (ii) the effects of general equitable principles, whether enforcement is considered in a proceeding in equity or law, (iii) an implied covenant of good faith and fair dealing, (iv) the discretion of the court before which any proceeding for enforcement may be brought, and (v) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to the public policy.

This opinion letter is limited to the matters stated herein, and no opinions may be implied or inferred beyond the matters expressly stated herein. We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.

We do not express any opinion herein concerning any law other than the laws of the State of New York and the federal laws of the United States.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of the name of our firm therein. In giving this consent, we do not admit that we are within the category of persons whose consent is required by Section 7 of the Securities Act.
