This letter agreement (the “Agreement”) is being made as of June 29, 2023, by and between Polar Asset Management Partners (“Polar”) and Priveterra Sponsor, LLC (“Sponsor”). Capitalized terms used, but not otherwise defined herein, shall have the meaning given to them in the Subscription Agreement (as defined below).

In this regard, Sponsor and Subscriber shall enter into a customary assignment agreement pursuant to Section 5.2.2 of that certain Registration Rights Agreement to be dated as of the Measurement Date (the “RRA”) to make Subscriber a “Permitted Transferee” (within the meaning of the RRA) such that Subscriber has the benefit of the RRA including any then effective registration statement covering the resale of such Additional Shares to the extent that such Additional Shares are not otherwise freely transferrable under the Securities Act of 1933, as amended. For the avoidance of doubt, in the event the Transfer VWAP for the Transferred PIPE Shares is equal to or more than $7.00 per share, then the Subscriber shall not be entitled to any Additional Shares. Notwithstanding anything to the contrary herein, no fraction of a Common Share will be delivered pursuant to this Agreement, and if the Subscriber would otherwise be entitled to a fraction of a Common Share, the Subscriber shall instead have the number of Additional Shares issued to the Subscriber rounded down to the nearest whole Common Share. All references in this Agreement to numbers of shares, per share amounts and share prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock combination, recapitalization or similar adjustment occurring after the date hereof.

For the purposes of this Agreement:

(i) “Additional Shares” means the lesser of (A) a number of Common Shares equal to the Make-Whole Amount divided by the VWAP (measured as of the date the Additional Shares are Transferred to Subscriber) and (B) 200,000 Common Shares;

(iii) “Measurement Period” means the period commencing on the Closing Date and ending on the earlier of (A) the date that is twenty-four (24) months after the date hereof, (B) the date on which the Forward Purchase Agreement terminates and (C) the date on which all PIPE Shares are sold;

(iv) “Measurement Date” means the last day of the Measurement Period,

(v) “Trading Day” means any day on which trading in the Common Shares generally occurs on the stock exchange on which the Common Shares are then listed or if the Common Shares are not so listed or traded, then “Trading Day” means a business day, and

(vi) “Transfer” means the (1) sale or assignment of, offer to sell, contract or agreement to sell, gift, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act of 1934 (as amended) with respect to any security, (2) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (3) public announcement of any intention to effect any transaction specified in clause (1) or (2).

(vii) “Transfer VWAP” means the average price per share at which Transferred PIPE Shares are Transferred during the Measurement Period (for the avoidance of doubt, without netting out broker commissions or other selling expenses);

(viii) “VWAP” means the per share volume weighted average price of the Common Shares as displayed under the heading “Bloomberg VWAP” on the applicable Bloomberg page (or, if such page is not available, its equivalent successor page) in respect of the five consecutive Trading Days ending on the Trading Day immediately prior to the measurement date (or, if such volume weighted average price is unavailable, the market value of one Common Share for such period, determined, using a volume weighted average price method, by a nationally recognized independent investment banking firm selected by the Sponsor). The VWAP will be determined without regard to after-hours trading or any other trading outside of the regular trading session.

a. Sponsor has full power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby.

c. The execution and delivery of this Agreement, the consummation of the transactions contemplated hereby and the performance by Sponsor of its obligations hereunder will not conflict with, or result in any violation of or default under, any agreement or other instrument to which Sponsor is a party or by which Sponsor is bound, or any decree, order, statute, rule or regulation applicable to Sponsor.

d. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Sponsor in connection with the consummation of the transactions contemplated by this Agreement.

e. There are no actions, suits, investigations or proceedings pending or threatened against Sponsor which: (i) seek to restrain, enjoin, prevent the consummation of the transactions contemplated by this Agreement or (ii) question the validity or legality of any such transactions or seek to recover damages or to obtain other relief in connection with any such transactions.

Within five (5) days following the end of each calendar month during the Measurement Period, Subscriber shall provide to Sponsor a reasonably detailed written report evidencing any Transfer of Shares made during such calendar month and the price at which such Transfer was made, in such form as reasonably acceptable to Sponsor.

SUPPLEMENT TO PROXY STATEMENT

OF

PRIVETERRA ACQUISITION CORP.

Dated June 29, 2023

The following disclosures in this proxy supplement (the “Supplement”) supplement, and should be read in conjunction with, the disclosures contained in the Company’s definitive proxy statement (the “Definitive Proxy Statement”), filed with the Securities and Exchange Commission (the “SEC”) on May 12, 2023, which in turn should be read in its entirety. To the extent the information set forth herein differs from or updates information contained in the Definitive Proxy Statement, the information set forth herein shall supersede or supplement the information in the Definitive Proxy Statement. All other information in the Definitive Proxy Statement remains unchanged.

As provided in the Definitive Proxy Statement, the Company is seeking shareholder approval of, among other things, a business combination with AEON Biopharma, Inc. (the “Business Combination Proposal”) and the issuance of common stock of the Company in connection with the business combination (the “Stock Issuance Proposal”). The purpose of the following supplemental disclosures is to provide information about certain additional equity financing arrangements (the “New Financing Agreements”) that have been entered into in connection with the business combination transaction and that will increase the number of shares of common stock of the Company that will be issued in connection with the business combination.

Terms used herein, unless otherwise defined, have the meanings set forth in the Definitive Proxy Statement.

DESCRIPTION OF NEW FINANCING AGREEMENTS

Forward Purchase Agreements

On June 29, 2023, Priveterra and AEON entered into separate agreements (each a “Forward Purchase Agreement”, and together, the “Forward Purchase Agreements”) with each of (i) ACM ARRT J LLC and (ii) Polar Multi-Strategy Master Fund (“Polar”, and each of ACM ARRT J LLC and Polar, individually, a “Seller”, and together, the “Sellers”) for OTC Equity Prepaid Forward Transactions. For purposes of each Forward Purchase Agreements, Priveterra is referred to as the “Counterparty” prior to the consummation of the Business Combination, while Pubco is referred to as the “Counterparty” after the consummation of the Business Combination. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Forward Purchase Agreements. Any reference herein to the `Forward Purchase Agreement' are to be treated as a reference to each Seller's separate agreement and should be construed accordingly and any action taken by a Seller should be construed as an action under its own respective agreement.

Pursuant to the terms of the Forward Purchase Agreements, the Sellers intend, but are not obligated, to purchase up to 7,500,000 shares of Class A common stock, par value $0.0001 per share, of Priveterra (“Priveterra Common Stock”) in the aggregate concurrently with the Closing pursuant to each Seller’s respective FPA Funding Amount PIPE Subscription Agreement (as defined below), less the number of shares of Priveterra Common Stock purchased by each Seller separately from third parties through a broker in the open market (“Recycled Shares”). No Seller shall be required to purchase an amount of shares of Priveterra Common Stock such that following such purchase, that Seller’s ownership would exceed 9.9% of the total shares of Priveterra Common Stock outstanding immediately after giving effect to such purchase, unless such Seller, at its sole discretion, waives such 9.9% ownership limitation. The Number of Shares subject to a Forward Purchase Agreement is subject to reduction following a termination of the Forward Purchase Agreements with respect to such shares as described under “Optional Early Termination” in the respective Forward Purchase Agreements.

Each Forward Purchase Agreement provides that a Seller will be paid directly an aggregate cash amount (the “Prepayment Amount”) equal to the product of (i) the Number of Shares as set forth in each Pricing Date Notice and (ii) the redemption price per share as defined in Section 9.2(a) of Priveterra’s Second Amended and Restated Certificate of Incorporation (the “Initial Price”).

The Counterparty will pay to each Seller separately the Prepayment Amount required under the respective Forward Purchase Agreement directly from the Counterparty’s Trust Account maintained by Continental Stock Transfer and Trust Company holding the net proceeds of the sale of the units in the Counterparty’s initial public offering and the sale of private placement warrants (the “Trust Account”) no later than the earlier of (a) one business day after the Closing Date and (b) the date any assets from the Trust Account are disbursed in connection with the Business Combination, except that to the extent the Prepayment Amount payable to a Seller is to be paid from the purchase of Additional Shares by such Seller pursuant to the terms of its FPA Funding Amount PIPE Subscription Agreement, such amount will be netted against such proceeds, with such Seller being able to reduce the purchase price for the Additional Shares by the Prepayment Amount. For the avoidance of doubt, any Additional Shares purchased by a Seller will be included in the Number of Shares for its respective Forward Purchase Agreement for all purposes, including for determining the Prepayment Amount.

2

Following the Closing, the reset price (the “Reset Price”) will initially be the Initial Price and subject to a $7.00 floor (the “Reset Price Floor”). The Reset Price will be subject to reset on a monthly basis (each a “Reset Date”) with the first such Reset Date occurring 90 days after the Closing Date to be the lowest of (a) the then-current Reset Price, (b) the Initial Price and (c) the 30-day VWAP Price of the Shares immediately preceding such Reset Date;

provided, however, that the Reset Price may be reduced immediately to any lower price at which the Counterparty sells, issues or grants any shares or securities convertible or exchangeable into shares (other than, among other things, grants or issuances under the Counterparty’s equity compensation plans, any securities issued in connection with the Business Combination or any securities issued in connection with the PIPE Subscription Agreements (as defined below)), subject to certain exceptions, in which case the Reset Price Floor would be eliminated.

From time to time and on any date following the Business Combination (any such date, an “OET Date”), any Seller may, in its absolute discretion, terminate its Forward Purchase Agreement in whole or in part by providing written notice to the Counterparty (the “OET Notice”), no later than the next Payment Date following the OET Date (which shall specify the quantity by which the Number of Shares shall be reduced (such quantity, the “Terminated Shares”)). The effect of an OET Notice shall be to reduce the Number of Shares by the number of Terminated Shares specified in such OET Notice with effect as of the related OET Date. As of each OET Date, the Counterparty shall be entitled to an amount from the Seller, and the Seller shall pay to the Counterparty an amount, equal to the product of (x) the number of Terminated Shares and (y) the Reset Price in respect of such OET Date. The payment date may be changed within a quarter at the mutual agreement of the parties.

The valuation date will be the earliest to occur of (a) the second anniversary of the Closing Date, (b) the date specified by a Seller in a written notice to be delivered to the Counterparty at a Seller’s discretion (which Valuation Date shall not be earlier than the day such notice is effective) after the occurrence of any of (w) a VWAP Trigger Event (x) a Delisting Event, (y) a Registration Failure or (z) unless otherwise specified therein, upon any Additional Termination Event and (c) 90 days after delivery by the Counterparty of a written notice in the event that for any 20 trading days during a 30 consecutive trading day-period that occurs at least six months after the Closing Date, the VWAP Price is less than the then applicable Reset Price, provided that a Registration Statement was effective and available for the entire measurement period and remains continuously effective and available during the entire 90 day notice period (the “Valuation Date”).

On the Cash Settlement Payment Date, which is the tenth local business day following the last day of the valuation period commencing on the Valuation Date, a Seller shall pay the Counterparty a cash amount equal to (1) (A) the Number of Shares as of the Valuation Date less the number of Unregistered Shares, multiplied by (B) the volume-weighted daily VWAP Price over the Valuation Period less (2) if the Settlement Amount Adjustment is less than the cash amount to be paid, the Settlement Amount Adjustment. The Settlement Amount Adjustment is equal to (1) the Number of Shares as of the Valuation Date multiplied by (2) $2.00 per share, and the Settlement Amount Adjustment will be automatically netted from the Settlement Amount. If the Settlement Amount Adjustment exceeds the Settlement Amount, the Counterparty will pay the Seller in shares of Priveterra Common Stock or, at the Counterparty’s election, in cash.

Each Seller has agreed to waive any redemption rights with respect to any Recycled Shares in connection with the Business Combination, as well as any redemption rights under Priveterra’s Second Amended and Restated Certificate of Incorporation that would require redemption by Priveterra of the Shares. Such waiver may reduce the number of shares of Priveterra Common Stock redeemed in connection with the Business Combination, and such reduction could alter the perception of the potential strength of the Business Combination. Each Forward Purchase Agreement has been structured, and all activity in connection with such agreement has been undertaken, to comply with the requirements of all tender offer regulations applicable to the Business Combination, including Rule 14e-5 under the Securities Exchange Act of 1934.
