THE OFFER IS BEING MADE SOLELY UNDER THIS OFFER LETTER AND THE

RELATED LETTER OF TRANSMITTAL AND CONSENT TO ALL HOLDERS OF WARRANTS.

Organogenesis Holdings Inc., a Delaware corporation (the “Company”), is making an offer, upon the terms and conditions in this Amended and Restated Offer to Exchange Letter (“Offer Letter”) and the related Amended and Restated Letter of Transmittal and Consent (the “Letter of Transmittal” and together with the Offer Letter, the “Offer”), to all holders of the Company’s issued and outstanding warrants that were issued in connection with our initial public offering pursuant to a prospectus dated October 10, 2016 (the “IPO Prospectus”), exercisable for shares of the Company’s Class A common stock, par value $0.0001 per share (the “Shares”), at an exercise price of $5.75 per half Share (the “Public Warrants”), to exchange during the Offer Period 0.095 Shares for each Public Warrant tendered. The “Offer Period” is the period commencing on July 22, 2019 and ending at 12:00 midnight, Eastern Time, on August 16, 2019, or such later date to which the Company may extend the Offer (the “Expiration Date”).

Concurrently with the Offer, we are also soliciting consents (the “Consent Solicitation”) from holders of the Public Warrants to amend (the “Warrant Amendment”) the warrant agreement (the “Warrant Agreement”) that governs all of the Public Warrants to permit the Company to require that each Public Warrant that is outstanding upon the closing of the Offer be converted into 0.0855 Shares, which is a ratio 10% less than the exchange ratio applicable to the Offer, thus eliminating all of the Public Warrants, as described in this Offer Letter.We are not seeking consents, and will not accept letters of transmittal to participate in the Offer and consent to the Warrant Amendment, until we have filed a definitive proxy statement with respect to the Consent Solicitation.If the Warrant Amendment is approved, we will not enter into the Warrant Amendment until at least 20 business days after the definitive proxy statement is sent to holders of Warrants.

One of the conditions to consummation of the Offer (which condition may be waived by the Company, in its sole discretion) is that holders of at least 65% of the outstanding Public Warrants are tendered in the Offer and Consent Solicitation. The execution and delivery of the Letter of Transmittal and Consent will constitute your consent to the Warrant Amendment and will also authorize and direct the Depository (as defined below) to execute and deliver a written consent to the Warrant Amendment on your behalf with respect to all Public Warrants that you tender. You must deliver your consent to the proposed Warrant Amendment in order to participate in the Offer and Consent Solicitation.

Our Shares are listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol ORGO and our Public Warrants are traded on the over-the-counter market (“OTC”) under the symbol ORGOW. On July 17, 2019, the

i

last reported sale prices for the Shares on Nasdaq was $6.40 and the Public Warrants on OTC was $0.51.Public Warrant holders should obtain current market quotations for the Shares and Public Warrants before deciding whether to tender their Public Warrants pursuant to the Offer.

The Offer relates to the Public Warrants issued pursuant to the IPO Prospectus, which trade through The Depository Trust Company (“DTC”). The Offer does not relate to the warrants issued by us in private placements that occurred contemporaneously with our initial public offering (the “Private Placement Warrants”), none of which are currently outstanding. Any and all outstanding Public Warrants issued pursuant to the IPO Prospectus are eligible to be tendered pursuant to the Offer. As of July 17, 2019, there were 30,890,748 Public Warrants outstanding.

The Offer is to permit holders of Public Warrants issued pursuant to the IPO Prospectus to tender any and all outstanding Public Warrants at an exchange ratio of 0.095 Shares for each Public Warrant tendered (approximately one Share for every 11 Public Warrants tendered). A holder may tender as few or as many Public Warrants as the holder elects. No fractional Shares will be issued. Public Warrants may only be exchanged for whole Shares. In lieu of issuing fractional Shares to which any holder of Public Warrants would otherwise have been entitled, the Company will round the number of Shares to which such holder is entitled, after aggregating all fractions, up to the next whole number of Shares. Holders are also entitled to exercise their Public Warrants during the Offer Period in accordance with the terms of the Public Warrant.

You may tender some or all of your Public Warrants on these terms.

If you elect to tender Public Warrants in response to the Offer and Consent Solicitation, please follow the instructions in this Offer Letter and the related documents, including the Letter of Transmittal. If you wish to exercise your Public Warrants in accordance with their terms, please follow the instructions for exercise included in the Public Warrants.

If you tender Public Warrants, you may withdraw your tendered Public Warrants at any time before the Expiration Date and retain them on their current terms or amended terms if the Warrant Amendment is approved, by following the instructions in this Offer Letter. If you withdraw the tender of your public warrants, your consent to the Warrant Amendment will be withdrawn as a result.

Investing in the Shares involves a high degree of risk. See “The Offer, Section 13. Forward-Looking Statements; Risk Factors” for a discussion of information that you should consider before tendering Public Warrants in the Offer.

The Offer and Consent Solicitation will commence on July 22, 2019 (the date the materials relating to the Offer and Consent Solicitation are first sent to the Public Warrant holders) and end on the Expiration Date.

A detailed discussion of the Offer and Consent Solicitation is contained in this Offer Letter. We may amend or terminate the Offer and Consent Solicitation at any time with requisite notice, as further described in this Offer Letter.

You should rely only on the information contained in this Offer Letter and in the Letter of Transmittal or to which we have referred you. We have not authorized anyone to provide you with information or to make any representation in connection with the Offer other than those contained in this Offer Letter or in the Letter of Transmittal.

SUMMARY

Unless otherwise stated in this Offer Letter, references to “we,” “our,” “us,” or the “Company” refer to Organogenesis Holdings Inc. An investment in our Shares involves risks. You should carefully consider the information provided under the heading “Forward-Looking Statements; Risk Factors” beginning on page 24.

Risks of Participating In the Offer

Participation in the Offer involves a number of risks, including, but not limited to, the risks identified in Section 13 below. Holders should carefully consider these risks and are urged to speak with their personal financial, investment and/or tax advisors as necessary before deciding whether to participate in the Offer. In addition, we strongly encourage you to read this Offer Letter in its entirety and review the documents referred to in Sections 8, 10, 13 and 15.

The Offer is to permit holders of Public Warrants issued pursuant to the IPO Prospectus to tender any and all outstanding Public Warrants at an exchange ratio of 0.095 Shares for each Public Warrant tendered (approximately one Share for every 11 Public Warrants tendered). A holder may tender as few or as many Public Warrants as the holder elects. No fractional Shares will be issued. Public Warrants may only be exchanged for whole Shares. In lieu of issuing fractional Shares to which any holder of Public Warrants would otherwise have been entitled, the Company will round the number of Shares to which such holder is entitled, after aggregating all fractions, up to the next whole number of Shares. Holders may also exercise their Public Warrants during the Offer Period in accordance with the terms of the Public Warrant.

You may tender some or all of your Public Warrants on these terms.The Offer relates to the Public Warrants issued pursuant to the IPO Prospectus, which trade through DTC. The Offer does not relate to the Private Placement Warrants, none of which are outstanding. Any and all outstanding Public Warrants are eligible to be tendered pursuant to the Offer. As of July 17, 2019, there were 30,890,748 Public Warrants outstanding.

If you elect to tender Public Warrants in response to the Offer, please follow the instructions in this Offer Letter and the related documents, including the Letter of Transmittal.

If you tender Public Warrants, you may withdraw your tendered Public Warrants before the Expiration Date and retain them on their terms by following the instructions herein.

The Shares to be exchanged for the Public Warrants have not been registered with the SEC. As described elsewhere in this Offer Letter, the issuance of the Shares upon exchange of the Public Warrants is exempt from the registration requirements of the Securities Act pursuant to Section 3(a)(9) thereof. Under current interpretations of the staff of the Division of Corporation Finance of the SEC, securities that are obtained in a Section 3(a)(9) exchange generally assume the same character (i.e., restricted or unrestricted) as the securities that have been surrendered. We are also relying on Section 18(b)(4)(E) of the Securities Act to exempt the Shares from the registration and qualification requirements of state securities laws.The Shares that you receive in the Offer will be freely-tradable, except by persons who are considered to be our affiliates, as that term is defined in the Securities Act.

As part of the Offer, we are also soliciting from the holders of the Public Warrants their consent to the amendment of the Warrant Agreement. If approved, the Warrant Amendment would permit the Company to require that each Public Warrant that is outstanding upon the closing of the Offer be converted into 0.0855 Shares, which is a ratio 10% less than the exchange ratio applicable to the Offer, thus eliminating all of the Public Warrants. A copy of the Warrant Amendment is attached hereto asAnnex A. We urge that you carefully read the Warrant Amendment in its entirety. Pursuant to the terms of the Warrant Agreement, the consent of holders of at least 65% of the outstanding Public Warrants is required to approve the Warrant Amendment.

Holders who tender Public Warrants in the Offer will automatically be deemed, without any further action, to have given their consent to approval of the Warrant Amendment (effective upon our acceptance of the Public Warrants tendered). The consent to the Warrant Amendment is a part of the letter of transmittal relating to the Public Warrants.

You cannot tender any Public Warrants in the Offer without giving your consent to the Warrant Amendment. Thus, before deciding whether to tender any Public Warrants, you should be aware that a tender of Public Warrants may result in the approval of the Warrant Amendment.

We are not seeking consents, and will not accept letters of transmittal to participate in the Offer and consent to the Warrant Amendment, until we have filed a definitive proxy statement with respect to the Consent Solicitation.If the Warrant Amendment is approved, we will not enter into the Warrant Amendment until at least 20 business days after the definitive proxy statement is sent to holders of Public Warrants.

A. Period of Offer

The Offer and Consent Solicitation will only be open for a period beginning on July 22, 2019 and ending on the Expiration Date. We expressly reserve the right, in our sole discretion, at any time or from time to time, prior to the Expiration Date, to extend the period of time during which the Offer and Consent Solicitation is open. There can be no assurance, however, that we will exercise our right to extend the Offer and Consent Solicitation.

B. Partial Tender Permitted

If you choose to participate in the Offer, you may tender less than all of your Public Warrants pursuant to the terms of the Offer.

HOWEVER, NONE OF THE COMPANY, ITS DIRECTORS, OFFICERS OR EMPLOYEES, NOR THE DEPOSITARY, THE INFORMATION AGENT OR THE FINANCIAL ADVISOR, MAKES ANY RECOMMENDATION AS TO WHETHER TO TENDER PUBLIC WARRANTS AND CONSENT TO THE WARRANT AMENDMENT. EACH HOLDER OF A PUBLIC WARRANT MUST MAKE HIS, HER OR ITS OWN DECISION AS TO WHETHER TO TENDER SOME OR ALL OF HIS, HER OR ITS PUBLIC WARRANTS AND CONSENT TO THE WARRANT AMENDMENT.

We expressly reserve the right, in our sole discretion, and at any time or from time to time, prior to the Expiration Date, to extend the period of time during which the Offer and Consent Solicitation is open. There can be no assurance, however, that we will exercise our right to extend the Offer and Consent Solicitation. If we extend the Offer and Consent Solicitation, we will give notice of such extension by press release or other public announcement no later than 9:00 a.m., Eastern Time, on the next business day after the previously scheduled Expiration Date of the Offer and Consent Solicitation.

A. Proper Tender of Public Warrants

To validly tender Public Warrants pursuant to the Offer, a properly completed and duly executed Letter of Transmittal or photocopy thereof, together with any required signature guarantees, must be received by the Depositary at its address set forth on the last page of this document prior to the Expiration Date. The method of delivery of all required documents is at the option and risk of the tendering Public Warrant holders. If delivery is by mail, the Company recommends registered mail with return receipt requested (properly insured). In all cases, sufficient time should be allowed to assure timely delivery.

In the Letter of Transmittal, the tendering Public Warrant holder must: (i) set forth his, her or its name and address; (ii) set forth the number of Public Warrants tendered; and (iii) set forth the number of the Public Warrant certificate(s) representing such Public Warrants.

Where Public Warrants are tendered by a registered holder of the Public Warrants who has completed either the box entitled “Special Issuance Instructions” or the box entitled “Special Delivery Instructions” on the Letter of Transmittal, all signatures on the Letters of Transmittal must be guaranteed by an “Eligible Institution.”

An “Eligible Institution” is a bank, broker, dealer, credit union, savings association or other entity that is a member in good standing of the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity which is an “eligible guarantor institution,” as that term is defined in Rule 17Ad-15 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

If the Public Warrants are registered in the name of a person other than the signer of the Letter of Transmittal, the Public Warrants must be endorsed or accompanied by appropriate instruments of assignment, in either case signed exactly as the name(s) of the registered owner(s) appear on the Public Warrants, with the signature(s) on the Public Warrants or instruments of assignment guaranteed.

A tender of Public Warrants pursuant to the procedures described below in this Section 2 will constitute a binding agreement between the tendering holder and the Company upon the terms and subject to the conditions of the Offer.

ALL DELIVERIES IN CONNECTION WITH THE OFFER, INCLUDING A LETTER OF TRANSMITTAL AND PUBLIC WARRANTS, MUST BE MADE TO THE DEPOSITARY OR THE BOOK-ENTRY TRANSFER FACILITY.

NO DELIVERIES SHOULD BE MADE TO THE COMPANY, AND ANY DOCUMENTS DELIVERED TO THE COMPANY WILL NOT BE FORWARDED TO THE DEPOSITARY OR THE BOOK-ENTRY TRANSFER FACILITY AND THEREFORE WILL NOT BE DEEMED TO BE PROPERLY TENDERED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

BOOK-ENTRY DELIVERY. The Depositary will establish an account for the Public Warrants at DTC for purposes of the Offer, within two business days after the date of this Offer Letter. Any financial institution that is a participant in DTC’s system may make book-entry delivery of Public Warrants by causing DTC to transfer such Public Warrants into the Depositary’s account in accordance with DTC’s procedure for such transfer. Even though delivery of Public Warrants may be effected through book-entry transfer into the Depositary’s account at DTC, a properly completed and duly executed Letter of Transmittal (or copy thereof), with any required signature guarantee, or an Agent’s Message (as defined below), and any other required documentation, must in any case be transmitted to and received by the Depositary at its address set forth on the last page of this Offer Letter prior to the Expiration Date, or the guaranteed delivery procedures set forth herein must be followed. Delivery of the Letter of Transmittal (or other required documentation) to DTC does not constitute delivery to the Depositary. The term “Agent’s Message” means a message, transmitted by DTC to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the participant in DTC exchanging the Public Warrants that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that the Company may enforce such agreement against the participant. The term “Book-Entry Confirmation” means a timely confirmation of a book-entry transfer of Public Warrants into the Depositary’s account at DTC.

PUBLIC WARRANTS HELD IN STREET NAME. If Public Warrants are held through a direct or indirect DTC participant, such as a broker, dealer, commercial bank, trust company or other financial intermediary, you must instruct that holder to tender your Public Warrants on your behalf. A letter of instructions is included in these

materials, and as an exhibit to the Schedule TO. The letter may be used by you to instruct a custodian to tender and deliver Public Warrants on your behalf.

Unless the Public Warrants being tendered are delivered to the Depositary by 12:00 midnight, Eastern Time, on August 16, 2019 (the Expiration Date) accompanied by a properly completed and duly executed Letter of Transmittal or a properly transmitted Agent’s Message, the Company may, at its option, treat such tender as invalid. Issuance of Shares upon tender of Public Warrants will be made only against the valid tender of Public Warrants.

GUARANTEED DELIVERY. If you want to tender your Public Warrants pursuant to the Offer, but (i) your Public Warrants are not immediately available, (ii) the procedure for book-entry transfer cannot be completed on a timely basis, or (iii) time will not permit all required documents to reach the Depositary prior to the Expiration Date, you can still tender your Public Warrants, if all of the following conditions are met:

(a) the tender is made by or through an Eligible Institution;

(b) the Depositary receives by hand, mail, overnight courier or fax, prior to the Expiration Date, a properly completed and duly executed Notice of Guaranteed Delivery in the form the Company has provided with this Offer Letter (with signatures guaranteed by an Eligible Institution); and

(c) the Depositary receives, within two Nasdaq trading days after the date of its receipt of the Notice of Guaranteed Delivery:

(1) the certificates for all tendered Public Warrants, or confirmation of receipt of the Public Warrants pursuant to the procedure for book-entry transfer as described above; and

(2) a properly completed and Proxy Statementduly executed Letter of Transmittal (or copy thereof), or any Agent’s Message in the case of a book-entry transfer, and any other documents required by the Letter of Transmittal.

In any event, the issuance of Shares for Public Warrants tendered pursuant to the Offer and accepted pursuant to the Offer will be made only after timely receipt by the Depositary of Public Warrants, properly completed and duly executed Letter(s) of Transmittal and any other required documents.

In that regard, a tender of Public Warrants authorizes us to withhold all applicable Tax Items potentially payable by a tendering Public Warrant holder. Our acceptance for payment of Public Warrants tendered pursuant to the Offer will constitute a binding agreement between the tendering Public Warrant holder and us upon the terms and subject to certain conditions of the Offer.

E. Signature Guarantees

Except as otherwise provided below, all signatures on a Letter of Transmittal by a person residing in or tendering Public Warrants in the United States must be guaranteed by an Eligible Institution.

See Instructions 1 and 5 of the Letter of Transmittal.

Tenders of Public Warrants made pursuant to the Offer may be rescinded at any time prior to the Expiration Date. Thereafter, such tenders are irrevocable. If the Company extends the period of time during which the Offer is open for any reason, then, without prejudice to the Company’s rights under the Offer and in a manner compliant with Rule 14e-1(c) of the Exchange Act, the Company may retain all Public Warrants tendered and tenders of such Public Warrants may not be rescinded, except as otherwise provided in this Section 3. Notwithstanding the foregoing, tendered Public Warrants may also be withdrawn if the Company has not accepted the Public Warrants for exchange by the 40th business day after the initial commencement of the Offer.

To be effective, a written notice of withdrawal must be timely received by the Depositary at its address identified in this Offer Letter. Any notice of withdrawal must specify the name of the holder who tendered the Public Warrants for which tenders are to be withdrawn and the number of Public Warrants to be withdrawn. If the Public Warrants to be withdrawn have been delivered to the Depositary, a signed notice of withdrawal must be submitted to the Depositary prior to release of such Public Warrants. In addition, such notice must specify the name of the registered holder (if different from that of the tendering Public Warrant holder). Withdrawal may not be cancelled, and Public Warrants for which tenders are withdrawn will thereafter be deemed not validly tendered for purposes of the Offer. However, Public Warrants for which tenders are withdrawn may be tendered again by following one of the procedures described in Section 2 at any time prior to the Expiration Date.

A holder of Public Warrants desiring to withdraw tendered Public Warrants previously delivered through DTC should contact the DTC participant through which such holder holds his, her or its Public Warrants. In order to withdraw previously tendered Public Warrants, a DTC participant may, prior to the Expiration Date, withdraw its instruction previously transmitted through DTC’s ATOP procedures by (i) withdrawing its acceptance, or (ii) delivering to the Depositary by mail, hand delivery or fax, a notice of withdrawal of such instruction. The notices of withdrawal must contain the name and number of the DTC participant. A withdrawal of an instruction must be executed by a DTC participant as such DTC participant’s name appears on its transmission to which such withdrawal relates. A DTC participant may withdraw a tendered Public Warrant only if such withdrawal complies with the provisions described in this paragraph.

For purposes of the Offer, the Company will be deemed to have accepted for exchange Public Warrants that are validly tendered and for which tenders are not withdrawn, unless the Company gives written notice to the Public Warrant holder of its non-acceptance prior to the Expiration Date.

If you tender Public Warrants pursuant to the Offer, and you are not an affiliate of the Company, you will receive unlegended Shares, which will be freely tradable.

Proxy Card or Voting Instruction Form

Record Date; Shares Outstanding and Entitled to Vote

        The Board has fixed the close of business on May 18, 2018 as the record date for the determination of the holders of our Class A ordinary shares, par value $0.0001 per share (the "Class A ordinary shares") and the Class B ordinary shares, par value $0.0001 per share (the "Class B ordinary shares," together with the Class A ordinary shares, the "ordinary shares") entitled to notice of and to vote at the meeting. Each shareholder will be entitled to one vote for each ordinary share held on all matters for which such shareholder is eligible to vote and that come before the meeting. Shareholders may vote in person or by proxy by completing the enclosed proxy card and returning it in the enclosed postage prepaid envelope or, as indicated on the proxy card, by voting on the Internet or by voting by

telephone. At the close of business on May 18, 2018 there were 31,000,000 Class A ordinary shares and 7,750,000 Class B ordinary shares entitled to vote.

Mailing Date

        This proxy statement and the accompanying form of proxy are first being sent to holders of the ordinary shares on or about May 31, 2018.

Broker Non-Votes

        A "broker non-vote" occurs when a brokerage firm or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have authority to vote on that particular proposal without receiving voting instructions from the beneficial owner. Under applicable stock exchange rules, brokers may not vote on "non-routine" proposals unless they have received voting instructions from the beneficial owner, and to the extent that they have not received voting instructions, brokers report such number of shares as "non-votes." The election of directors is considered a "non-routine" item, which means that brokerage firms may not vote in their discretion regarding these items on behalf of beneficial owners who have not furnished voting instructions. The proposal to ratify the selection of independent auditors, however, is considered a "routine" item, which means that brokerage firms may vote in their discretion regarding the selection of independent auditors on behalf of beneficial owners who have not furnished voting instructions. Because at least one routine item is to be voted upon at the meeting, broker non-votes will be counted for purposes of determining the presence or absence of a quorum for the transaction of business at the 2018 Annual General Meeting.

Required Votes for Each Proposal and Recommendation of the Board of Directors

        Abstentions or withhold votes, as applicable, and broker non-votes will have no effect on the election of directors. Abstentions will have no effect on the ratification of independent auditors.

Voting and Revocation of Proxies

        Shareholders are requested to vote by proxy in one of three ways:

•

Use the toll-free telephone number shown on your proxy card;



•

Visit the Internet website at www.voteproxy.com and follow the on-screen instructions; or



•

Mail, date, sign and promptly return your proxy card in the enclosed postage prepaid envelope.

        Ordinary shares represented by properly executed proxies received by us or proxies submitted by telephone or via the Internet, which are not revoked, will be voted at the meeting in accordance with the instructions contained therein. Subject to the broker non-vote rules discussed above under "Required Votes for Each Proposal," if instructions are not given, proxies will be votedfor the election of each nominee for director named andfor ratification of the selection of our independent auditors.

        Voting instructions (including instructions for both telephonic and Internet voting) are provided on the proxy card. The Internet and telephone voting procedures are designed to authenticate shareholder

identities, to allow shareholders to give voting instructions and to confirm that shareholders' instructions have been recorded properly. A control number, located on the proxy card, will identify shareholders and allow them to vote or submit their proxies and confirm that their voting instructions have been properly recorded. Costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, must be borne by the shareholder. If you vote or submit your proxy by Internet or telephone, it will not be necessary to return your proxy card.

        If your shares are held in the name of a bank or broker, follow the voting instructions on the form you receive from your record holder. The availability of Internet and telephone voting will depend on their voting procedures.

        If a shareholder does not return a signed proxy card or submit a proxy by the Internet or by telephone, and does not attend the meeting and vote in person, his or her shares will not be voted.

        Any proxy signed and returned by a shareholder or submitted by telephone or via the Internet may be revoked at any time before it is exercised by giving written notice of revocation to the General Counsel and Secretary of the Company, at our address set forth herein, by executing and delivering a later-dated proxy (either in writing, by telephone or via the Internet) or by voting in person at the meeting. Attendance at the meeting will not in and of itself constitute revocation of a proxy. If your shares are held in a brokerage, bank, or other institutional account, you must obtain a proxy from that entity showing that you were the record holder as of the close of business on May 18, 2018, in order to vote your shares at the meeting.

Electronic Delivery of Annual Report and Proxy Materials

        This proxy statement and the accompanying Annual Report are available at: www.proxyvote.com.

"Householding" of Annual Report and Proxy Materials

        We have adopted a procedure approved by the Securities and Exchange Commission (the "SEC") called "householding." Under this procedure, shareholders of record who have the same address and last name will receive only one copy of our Annual Report and proxy statement unless one or more of these shareholders notifies us that they wish to continue receiving individual copies. This procedure will reduce our printing costs and postage fees. Shareholders who participate in householding will continue to receive separate proxy cards. Also, householding will not in any way affect dividend check mailings, if any.

        If you are eligible for householding, but you and other shareholders of record with whom you share an address currently receive multiple copies of the Annual Report and/or the proxy statement, or if you hold shares in more than one account, and in either case you wish to receive only a single copy of each of these documents for your household, please contact Broadridge Financial Solutions, Inc. at (866) 540-7095 or write to: Householding Department, 51 Mercedes Way, Edgewood, New York 11717. If you do not wish to participate in householding and prefer to receive separate copies of these documents in the future, please contact Continental Stock Transfer and Trust Company as indicated above and we will deliver promptly a separate copy of the Annual Report and proxy statement to you.

        Beneficial shareholders can request information about householding from their banks, brokers or other holders of record.

Proxy Solicitation

        We will bear the costs of solicitation of proxies for the Annual General Meeting. In addition to solicitation by mail, directors and officers may solicit proxies from shareholders by telephone, in person or otherwise. These directors and officers will not receive additional compensation, but may be reimbursed for out-of-pocket expenses in connection with this solicitation. Solicitation will be conducted

by our directors and officers and we will bear all costs associated with such solicitation. Brokers, nominees, fiduciaries and other custodians have been requested to forward soliciting material to the beneficial owners of our ordinary shares held of record by them, and such custodians will be reimbursed for their reasonable expenses.

Independent Auditors

        We have been advised that representatives of Marcum LLP, our independent auditors for 2017, will not attend the 2018 Annual General Meeting, and therefore will not have an opportunity to make a statement or respond to questions.

All of the following nominees are currently serving as directors. The persons named in the enclosed form of proxy have advised that, unless contrary instructions are received, they intend to vote for the six nominees named by the Board and listed on the following table. The Board expects that each of the nominees will be available for election as a director. However, if by reason of an unexpected occurrence one or more of the nominees is not available for election, the persons named in the form of proxy have advised that they will vote for such substitute nominees as the Board may propose. The following information is as of May 18, 2018.

On October 14, 2016, we completed anAHPAC consummated its initial public offering, following which its shares began trading on the Nasdaq Capital Market. On December 10, 2018, in a transaction referred to as the “Business Combination,” AHPAC re-domesticated as a Delaware corporation and consummated a business combination with Organogenesis Inc. (“Organogenesis”).

B. Establishment of Offer Terms; Approval of the Offer

Our board of directors approved this Offer and Consent Solicitation and the exchange ratio and other terms of this Offer and Consent Solicitation. The board of directors set the exchange ratio in order to provide the holders of the Public Warrants with an incentive to exchange the Public Warrants, without resulting in the issuance of a number of Shares that the board considered to be overly dilutive. The board believed that the exchange ratio provides holders of the Public Warrants with an incentive to exchange the Public Warrants for Shares because, based on recent trading prices of the Shares and Public Warrants, the market value of one Share is greater than that of 12 Public Warrants, and holders who exchange Public Warrants, which are currently out of the money, will receive a more liquid security.

C. Purpose of the Offer

The Offer and Consent Solicitation is being made to all holders of Public Warrants. The purpose of the Offer is to reduce the number of Shares that would become outstanding upon the exercise of Public Warrants. The Company’s board of directors believes that by allowing holders of Public Warrants to exchange one Public Warrant for 0.095 Shares, the Company can potentially reduce, or eliminate, the substantial number of Shares that would be issuable upon exercise of the Public Warrants, thus providing investors and potential investors with greater certainty as to the Company’s capital structure. For example, if all of the outstanding Public Warrants were validly tendered in the Offer, the Company would issue approximately 2,934,622 Shares in exchange for such tendered Public Warrants. However, if all of the outstanding Public Warrants were exercised for Shares pursuant to the terms of the Public Warrants, the Company would issue 15,445,374 Shares in such exercise. The Public Warrants acquired pursuant to the exchange will be retired and cancelled. The Offer is not made pursuant to a plan to periodically increase any securityholder’s proportionate interest in the assets or earnings and profits of the Company.

D. Interests of Directors and Executive Officers

The names of the executive officers and directors of the Company are set forth below. The business address for each such person is: c/o Organogenesis Holdings Inc., 85 Dan Road, Canton, Massachusetts 02021 and the telephone number for each such person is (781) 575-0775.

As of July 17, 2019, the Company had 91,343,389 outstanding shares of Class A Common Stock, no outstanding shares of Class B Common Stock and 30,890,748 outstanding Public Warrants. The Shares issuable upon

exchange of the outstanding Public Warrants pursuant to the Offer represent approximately 3.21% of our units, whichoutstanding Shares as of July 17, 2019.

To our knowledge, none of our directors or executive officers beneficially own Public Warrants.

The Company does not beneficially own any Public Warrants.

On July 17, 2019, the last reported sale prices for the Shares on Nasdaq was $6.40 and the Public Warrants on OTC was $0.51.

The Company recommends that holders consider current market quotations for the Shares and the Public Warrants, among other factors, before deciding whether or not to tender their Public Warrants.

The table below indicates the implied Public Warrant value at various hypothetical stock prices based on the exchange ratio of 0.095 Shares per Public Warrant. The implied Public Warrant value is calculated by multiplying the prices per Share in the table below by the exchange ratio. The stock prices below are included for illustrative purposes only and there can be no assurance that the Shares will trade at such prices prior to, at or after the expiration of the Offer.

7. SOURCE AND AMOUNT OF FUNDS

The Board believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. In accordance with Rule 5605(e)(1)(A) of the NASDAQ rules, all such directors are independent. As there is no standing nominating committee, the Company does not have a nominating committee charter in place.

The Controlling Entities also agreed to vote their shares of our common stock in support of such nominees, and to appoint each of Alan A. Ades, Albert Erani and Glenn H.

Based solely upon a review of such Forms, we believe that during the year ended December 31, 2017 there were no delinquent filers.

EXECUTIVE COMPENSATION
Compensation Discussion and Analysis

        We do not have any employees. Additionally, none of our officers or directors have received any cash compensation for services rendered to us. Commencing on October 11, 2016, and until the earlier of the consummation of a business combination or our liquidation, we will pay an affiliate of our Sponsor a total of $10,000 per month for office space, administrative and support services. Our Sponsor, officers and directors, or any of their respective affiliates, will be reimbursed for any out of

pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our Audit Committee will review on a quarterly basis all payments that were made to our Sponsor, officers, directors or our or their affiliates.

 We do not intend to take any action to ensure that members of our management team maintain their positions with us after the consummation of a business combination, although it is possible that some or all of our officers and directors may negotiate employment or consulting arrangements to remain with us after the business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management's motivation in identifying or selecting a target business but we do not believe that the ability of our management team to remain with us after the consummation of a business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for benefits upon termination of employment.

11. CONDITIONS; TERMINATION; WAIVERS; EXTENSIONS; AMENDMENTS

The conditions of the Offer are:

i. there shall not have been instituted, threatened in writing or be pending any action or proceeding before or by any court or governmental, regulatory or administrative agency or instrumentality, or by any other person, in connection with the Offer, that is, or is reasonably likely to be, in our reasonable judgment, materially adverse to our business, operations, properties, condition, assets, liabilities or prospects, or which would or might, in our reasonable judgment, prohibit, prevent, restrict or delay consummation of the Offer or materially impair the contemplated benefits to us of the Offer;

ii. no order, statute, rule, regulation, executive order, stay, decree, judgment or injunction shall have been proposed, enacted, entered, issued, promulgated, enforced or deemed applicable by any court or governmental, regulatory or administrative agency or instrumentality that, in our reasonable judgment, would or would be reasonably likely to prohibit, prevent, restrict or delay consummation of the Offer or materially impair the contemplated benefits to us of the Offer, or that is, or is reasonably likely to be, materially adverse to our business, operations, properties, condition, assets, liabilities or prospects;

iii. in our reasonable judgment, there shall not have occurred or be reasonably likely to occur, any material adverse change to our business, operations, properties, condition, assets, liabilities, prospects or financial affairs; and

iv. there shall not have occurred:

a. any general suspension of, or limitation on prices for, trading in securities in U.S. securities or financial markets;

b. any material adverse change in the price of the Shares in U.S. securities or financial markets;

c. a declaration of a banking moratorium or any suspension of payments in respect to banks in the United States;

d. any limitation (whether or not mandatory) by any government or governmental, regulatory or administrative authority, agency or instrumentality, domestic or foreign, or other event that, in our reasonable judgment, would or would be reasonably likely to affect the extension of credit by banks or other lending institutions; or

e. a commencement or significant worsening of a war or armed hostilities or other national or international calamity, including but not limited to, catastrophic terrorist attacks against the United States or its citizens.

v. at least 65% of the Public Warrants (which is the minimum number required to amend the Warrant Agreement) are tendered in the Offer and Consent Solicitation.

The foregoing conditions are solely for our benefit, and we may assert one or more of the conditions regardless of the circumstances giving rise to any such conditions. We may also, in our sole and absolute discretion, waive these conditions in whole or in part, subject to the potential requirement to disseminate additional information and extend the Offer and Consent Solicitation, as described below. The determination by us as to whether any condition has been satisfied shall be conclusive and binding on all parties. The failure by us at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed a continuing right which may be asserted at any time and from time to time prior to the Expiration Date.

We may terminate the Offer and Consent Solicitation if any of the conditions of the Offer are not satisfied prior to the Expiration Date. In the event that we terminate the Offer and Consent Solicitation, all Public Warrants tendered by a Public Warrant holder in connection with the Offer will be returned to such Public Warrant holder and the Public Warrants will expire in accordance with their terms on December 10, 2023 and will otherwise remain subject to their original terms, including the redemption provisions.

Subject to applicable securities laws and the terms and conditions set forth in this Offer Letter, we expressly reserve the right (but will not be obligated), at any time or from time to time, prior to the Expiration Date, regardless of whether or not any of the events set forth above shall have occurred or shall have been determined by us to have occurred, to (a) waive any and all conditions of the Offer and Consent Solicitation, (b) extend the Offer and Consent Solicitation, or (c) otherwise amend the Offer and Consent Solicitation in any respect. The rights reserved by us in this paragraph are in addition to our rights to terminate the Offer and Consent Solicitation described above. Irrespective of any amendment to the Offer and Consent Solicitation, all Public Warrants previously tendered pursuant to the Offer and Consent Solicitation and not accepted for exchange or withdrawn will remain subject to the Offer and Consent Solicitation and may be accepted thereafter for exchange by us.

If we materially change the terms of the Offer and Consent Solicitation or the information concerning the Offer and Consent Solicitation, or if we waive a material condition to the Offer and Consent Solicitation, we will disseminate additional information and extend the Offer and Consent Solicitation to the extent required by Exchange Act Rules 13e-4(d)(2) and 13e-4(e)(3). In addition, we may, if we deem appropriate, extend the Offer and Consent Solicitation for any other reason. In addition, if the exchange ratio for Shares to Public Warrants is adjusted, the Offer and Consent Solicitation will remain open at least ten (10) business days from the date we first give notice of such change to Public Warrant holders, by press release or otherwise.

Any extension, amendment or termination of the Offer and Consent Solicitation by us will be followed promptly by a public announcement thereof. Without limiting the manner in which we may choose to make such announcement, we will not, unless otherwise required by law, have any obligation to advertise or otherwise communicate any such announcement other than by making a release to the Dow Jones News Service, Globe Newswire or such other means of public announcement as we deem appropriate.

If for any reason the acceptance for exchange (whether before or after any Public Warrants have been accepted for exchange pursuant to the Offer and Consent Solicitation), or the exchange for, Public Warrants subject to the Offer and Consent Solicitation is delayed or if we are unable to accept for exchange, or exchange for, Public Warrants pursuant to the Offer and Consent Solicitation, then, without prejudice to our rights under the Offer and Consent Solicitation, tendered Public Warrants may be retained by the Depositary on our behalf and may not be withdrawn (subject to Exchange Act Rule 14e-1(c), which requires that an offeror deliver the consideration offered or return the securities deposited by or on behalf of the investor promptly after the termination or withdrawal of a tender offer). In addition to being limited by Exchange Act Rule 14e-1(c), our reservation of the right to delay delivery of the Shares for Public Warrants which we have accepted for exchange pursuant to the Offer and Consent Solicitation is limited by Exchange Act Rule 13e-4(f)(5), which requires that an offeror deliver the consideration offered or return the securities tendered pursuant to a tender offer promptly after

termination or withdrawal of that tender offer. Notwithstanding the foregoing, tendered Public Warrants may also be withdrawn if the Company has not accepted the Public Warrants for exchange by the 40th business day after the initial commencement of the Offer and Consent Solicitation.

Pursuant to Exchange Act Rule 13e-4, we have filed the Schedule TO with the SEC which contains additional information with respect to the Offer and Consent Solicitation. The Schedule TO, including the exhibits and any amendments thereto, may be examined, and copies may be obtained, at the same places and in the same manner as set forth under “Additional Information; Miscellaneous” in this Offer Letter.

12. MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material U.S. federal income tax consequences to holders that own and hold Public Warrants as capital assets, within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), and that exchange Public Warrants for Shares pursuant to the Offer. This discussion does not address all of the tax consequences that may be relevant to a holder based on his, her or its individual circumstances and does not address tax consequences applicable to holders that may be subject to special tax rules, such as: financial institutions; insurance companies; regulated investment companies; tax-exempt organizations; dealers or traders in securities or currencies; holders that actually or constructively own 5% or more of our Shares; holders that hold Public Warrants as part of a position in a straddle or a hedging, conversion or integrated transaction for U.S. federal income tax purposes; holders that have a functional currency other than the U.S. dollar; holders that received their Public Warrants as compensation for the performance of services; or holders that are not U.S. persons (as defined for U.S. federal income tax purposes). Moreover, this summary does not address any state, local or foreign tax consequences or any U.S. federal non-income tax consequences of the exchange of Public Warrants for Shares pursuant to the Offer or, except as discussed herein, any tax reporting obligations of a holder. Holders should consult their tax advisors as to the specific tax consequences to them of the Offer in light of their particular circumstances.

If an entity treated as a partnership for U.S. federal income tax purposes holds Public Warrants, the tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Holders owning their Public Warrants through a partnership should consult their tax advisors regarding the U.S. federal income tax consequence of exchanging Public Warrants for Shares pursuant to the Offer.

This summary is based on the Code, applicable Treasury regulations, administrative pronouncements and judicial decisions, each as in effect on the date hereof. All of the foregoing are subject to change, possibly with retroactive effect, or differing interpretations by the Internal Revenue Service (“IRS”) or a court, which could affect the tax consequences described herein.

The Company believes that the exchange of Public Warrants for Shares pursuant to the Offer constitutes a value-for-value exchange. Assuming the exchange of Public Warrants for Shares pursuant to the Offer constitutes a value-for-value exchange, the exchange should be treated as a “recapitalization” within the meaning of Section 368(a)(1)(E) of the Code pursuant to which (i) no gain or loss should be recognized on the exchange of Public Warrants for Shares, (ii) a holder’s aggregate tax basis in the Shares received in the exchange should equal the holder’s aggregate tax basis in its Public Warrants surrendered in exchange therefor, and (iii) a holder’s holding period for the Shares received in the exchange should include its holding period for the surrendered Public Warrants. Special tax basis and holding period rules apply to holders that acquired different blocks of Public Warrants at different prices or at different times. Holders should consult their tax advisors as to the applicability of these special rules to their particular circumstances.

Although the Company believes the exchange pursuant to the Offer is a value-for-value transaction, because of the uncertainty inherent in any valuation, there can be no assurance that the IRS or a court would agree. If the IRS or a court were to view the exchange pursuant to the Offer as the issuance of Shares to an exchanging holder having a value in excess of the Public Warrants surrendered by such holder, such excess value could be viewed as a constructive dividend under Section 305 of the Code. Although not free from doubt, it is expected that such

constructive dividend, if any, should be considered a dividend of common stock on common stock, which generally should be nontaxable for most holders.

Holders are urged to consult their personal tax advisors concerning the tax consequences of an exchange pursuant to Offer based on their particular circumstances.

13. FORWARD-LOOKING STATEMENTS; RISK FACTORS

This Offer Letter contains forward-looking statements as defined in Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward looking statements usually relate to future events, conditions and anticipated revenues, earnings, cash flows or other aspects of our operations or operating results. Forward-looking statements are often identified by the words “believes,” “expects,” “intends,” “estimates,” “projects,” “anticipates,” “will,” “plans,” “may,” “should,” or the negative thereof or similar terms. The absence of these words, however, does not mean that these statements are not forward-looking. These are based on our current expectation, belief and assumptions concerning future developments and business conditions and their potential effect on us. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future development affecting us will be those that we anticipate.

All of our forward-looking statements involve risks and uncertainties (some of which are significant or beyond our control) and assumptions that could cause actual results to differ materially from our historical experience and our present expectations or projections. Known material factors that could cause actual results to differ materially from those contemplated in the forward-looking statements include those set forth in this “Item 12. Forward-Looking Statements; Risk Factors.” We caution you not to place undue reliance on any forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any of our forward-looking statements after the date they are made, whether as a result of new information, future events, or otherwise, except to the extent required by law.

An investment in our Shares involves a high degree of risk. In addition to the risks identified below relating to the Offer, please refer to our filings with the SEC, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, filed on March 18, 2019, as amended, and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2019, filed on May 9, 2019, for a discussion of risks relating to our business and an investment in our Shares. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. If any of the matters identified as potential risks materialize, our business could be harmed. In that event, the trading price of our Shares and Public Warrants could decline.

The Warrant Amendment, if approved, will allow us to require that all outstanding Public Warrants be exchanged for Shares.

If we complete the Offer and Consent Solicitation and obtain the requisite approval of the Warrant Amendment by holders of the Public Warrants, the Company will have the right to require holders of all outstanding Public Warrants, including holders who do not wish to participate and did not participate in the Offer, to exchange their Warrants for Shares, at a ratio 10% less than the exchange ratio applicable to the Offer, thus eliminating all of the outstanding Public Warrants.

There is no guarantee that your decision whether to tender your Public Warrants in the Offer will put you in a better future economic position.

We can give no assurance as to the price at which a stockholder may be able to sell his, her or its Shares in the future following the completion of the Offer. If you choose to tender some or all of your Public Warrants in the Offer, certain future events (including, without limitation, those described in “The Offer, Section 5.E, Plans, Proposals or Negotiations”), which may be significant and may happen quickly at any time in the future, may result in you realizing a lower value than you might have realized in the future had you not agreed to exchange

your Public Warrants. Similarly, if you do not tender your Public Warrants in the Offer, you will continue to bear the risk of ownership of your Public Warrants after the closing of the Offer, and there can be no assurance that you can sell your Public Warrants (or exercise them for Shares) in the future at a higher price than would have been obtained by participating in the Offer or at all. You should carefully review the terms of the Public Warrants, including the Public Warrant Agreement governing the Public Warrants, and consult your own individual tax and/or financial advisor for assistance on how the tender of your Public Warrants may affect your individual situation.

If the Offer is successful, the liquidity of the market for the Public Warrants will be substantially reduced.

If the Offer is successful, the holders of Public Warrants who tender their Public Warrants will receive Shares that are listed on Nasdaq, and the liquidity of the market for any remaining Public Warrants, which are listed on OTC, will be substantially reduced.

There is no assurance that a significant number of Public Warrants will be tendered in the Offer.

There is no assurance that any significant number of Public Warrants will be tendered in the Offer. Moreover, even if a significant number of Public Warrants are tendered in the Offer, there is no assurance that the market price of our Shares will increase. The price of our Shares and the decision of any investors to make an equity investment in the Company are based on numerous material factors, of which the dilutive impact of our outstanding Public Warrants, or overhang, is only one. Eliminating or significantly reducing our Public Warrant overhang will not generate any capital for the Company.

The market price of our Shares will fluctuate, which may adversely affect Public Warrant holders who tender their Public Warrants for Shares.

The market price of our Shares will fluctuate between the date the Offer is commenced, the Expiration Date of the Offer and the date on which Shares are issued to tendering Public Warrant holders. Accordingly, the market price of Shares upon settlement of the Offer could be less than the price at which the Public Warrants could be sold. The Company does not intend to adjust the exchange ratio of Shares for Public Warrants based on any fluctuation in our Share price.

Resales of the additional Shares issued pursuant to the Offer may adversely affect the Share price.

Shares issued in the Offer will be freely tradable, unless held by affiliates. In light of the current trading volume of our Shares, if the holders of the Public Warrants were to sell a significant portion of the Shares obtained from the Offer, such sales could have a negative impact on the trading price of our Shares.

No rulings or opinions have been received as to the tax consequences of the Offer to holders of Public Warrants.

The tax consequences that will result to Public Warrant holders that participate in the Offer are not well defined by the existing authorities. No ruling of any governmental authority and no opinion of counsel has been issued or rendered on these matters. Public Warrant holders must therefore rely on the advice of their own tax advisors in assessing these matters. For a general discussion of certain tax considerations, see “The Offer, Section 12. Material U.S. Federal Income Tax Consequences.”

14. THE DEPOSITARY, INFORMATION AGENT AND FINANCIAL ADVISOR

We have retained Continental Stock Transfer & Trust Company, to act as the Depositary, and Morrow Sodali LLC, to act as the Information Agent, in connection with the Offer. All deliveries, correspondence and questions sent or presented to the Depositary or the Information Agent relating to the Offer should be directed to the

addresses or telephone numbers set forth on the back cover of this Offer Letter. The Information Agent and the Depositary will receive reasonable and customary compensation for their respective services, will be reimbursed by us for reasonable out-of-pocket expenses and will be indemnified against certain liabilities in connection with the Offer, including certain liabilities under the federal securities laws.

We also retained Credit Suisse Securities (USA) LLC to act as a financial advisor in connection with a financial restructuring of the Company’s outstanding warrants. Credit Suisse will only provide customary and permissible services for a financial advisor within the scope of transactions conducted under Section 3(a)(9) of the Securities Act of 1933, as amended, and will not engage, directly or indirectly, in soliciting tenders of Public Warrants pursuant to the Offer.

We will not pay any fees or commissions to brokers, dealers or other persons (other than fees to the Information Agent as described above) for soliciting tenders of Public Warrants pursuant to the Offer. Public Warrant holders holding Public Warrants through a broker, dealer, commercial bank, trust company or other nominee are urged to consult such nominees to determine whether transaction costs may apply if Public Warrant holders tender Public Warrants through such nominees and not directly to the Depositary. We will, however, upon request, reimburse brokers, dealers, commercial banks, trust companies and other nominees for customary mailing and handling expenses incurred by them in forwarding the Offer and related materials to the beneficial owners of Public Warrants held by them as a nominee or in a fiduciary capacity. No broker, dealer, commercial bank, trust company or other nominee has been authorized to act as our agent or the agent of the Information Agent or the Depositary for purposes of the Offer.

PROPOSAL NO. 2: RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS
Warrant Agreement Amendment]

        The ratification of the selection of Marcum LLP as independent auditors is being submitted to shareholders because we believe that this action follows sound corporate practice and is in the best interests of the shareholders. If the shareholders do not ratify the selection by the affirmative vote of the holders of a majority of the ordinary shares voted at the meeting, the Audit Committee of the Board may reconsider the selection of independent auditors, but such a vote will not be binding on the Audit Committee. If the shareholders ratify the selection, the Audit Committee, in its discretion, may still direct the appointment of new independent auditors at any time during the year if they believe that this change would be in our and our shareholders' best interests.

        The Board recommends that the shareholders ratify the selection of Marcum LLP, an independent registered public accounting firm, as the independent auditors to audit our accounts and those of our subsidiaries for 2018. The Audit Committee approved the selection of Marcum LLP as our independent auditors for 2018. Marcum LLP are currently our independent auditors.

        Accordingly, we ask our shareholders to vote on the following resolution:

        "Resolved, that the selection of Marcum LLP as independent auditors for the year ended December 31, 2018 be ratified, approved and confirmed in all respects."

        The Board of Directors recommends a vote FOR this proposal.
