Item 1.01

Entry into a Material Definitive Agreement

As previously disclosed, Atlantic Coastal Acquisition Corp. II, a Delaware corporation (“we,” “ACAB” the “Company” or “PubCo” upon and following the Business Combination (as defined herein)) entered into an agreement in connection with a proposed business combination (the “Business Combination”) with Abpro Corporation, a Delaware Corporation (“Abpro”).

As previously disclosed, on October 18, 2024, the Company’s Registration Statement on Form S-4 (the “Registration Statement”) relating to the Business Combination went effective, and the Company filed the proxy statement/prospectus relating to the Business Combination.

Forward Purchase Agreement

On November 7, 2024, the Company and Abpro entered into a Confirmation of an OTC Equity Prepaid Forward Transaction (the “Forward Purchase Agreement”) with YA II PN, LTD. (the “Seller”) to which a maximum of up to 500,000 Shares (as defined below) (the “Maximum Number of Shares”) will be subject. For purposes of the Forward Purchase Agreement, (i) the Company 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 and (ii) “Shares” means shares of the Series A common stock, par value $0.0001 per share, of the Company prior to the closing of the Business Combination (“ACAB Shares”), and, after the closing of the Business Combination, shares of common stock, par value $0.0001 per share, of PubCo (“PubCo Shares”). Capitalized terms used herein but not otherwise defined have the meanings ascribed to such terms in the Forward Purchase Agreement.

Pursuant to the terms of the Forward Purchase Agreement, the Seller intends, but is not obligated, to purchase up to 500,000 Shares from third parties (other than Counterparty) through a broker in the open market (other than through Counterparty) (“Recycled Shares”). The Seller will not be required to purchase an amount of Shares such that following such purchase, the Seller’s ownership would exceed 9.9% of the total Shares outstanding immediately after giving effect to such purchase, unless the Seller, at its sole discretion, waives such 9.9% ownership limitation. The number of Recycled Shares subject to the Forward Purchase Agreement (being in no event more than the Maximum Number of Shares, the “Number of Shares”) is subject to reduction following a termination of the Forward Purchase Agreement with respect to such shares as described under “Optional Early Termination” in the Forward Purchase Agreement.

The Forward Purchase Agreement provides that the 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 a Pricing Date Notice and (ii) the redemption price per share as defined in Section 9.2(a) of the Amended and Restated Certificate of Incorporation of ACAB, effective as of January 18, 2022, as amended from time to time (the “Initial Price”).

The Counterparty will pay to the Seller the Prepayment Amount required under the Forward Purchase Agreement directly from the Counterparty’s trust account maintained by Continental Stock Transfer & 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 New York business day after the date of the closing of the Business Combination pursuant to the Business Combination Agreement (the “Closing Date”) and (b) the date any assets from the Trust Account are disbursed in connection with the Business Combination.

The reset price (the “Reset Price”) will initially be $10.00. The Reset Price will be subject to reset on a weekly basis commencing with the first full week following the Closing Date, to be the lowest of (a) the then current Reset Price, (b) $10.00 and (c) the VWAP Price of the Shares of the last 3 trading days in such week; provided, that in the event of a Dilutive Offering by the Counterparty, the Reset Price will also be reduced to equal the effective price per share in such Dilutive Offering immediately upon the occurrence of such Dilutive Offering. Furthermore, in the event that the Counterparty engages in a stock split, a reverse stock split or pays dividends in the form of Shares, the Reset Price shall be adjusted to reflect the effect thereof.

From time to time and on any date following the Trade Date (any such date, an “OET Date”) and subject to the terms and conditions in the Forward Purchase Agreement, the Seller may, in its absolute discretion, terminate the Transaction in whole or in part by providing written notice to the Counterparty (the “OET Notice”), by no later than the next Payment Date following the OET Date, (which will specify the quantity by which the Number of Shares will be reduced (such quantity, the “Terminated Shares”)). The effect of an OET Notice will 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 will be entitled to an amount from the Seller, and the Seller will 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 month at the mutual agreement of the parties.

The “Valuation Date” is the earliest to occur of (a) the date that is 3 months after the Closing Date and (b) the date specified by the Seller in a written notice to be delivered to the Counterparty at the Seller’s discretion (which Valuation Date will not be earlier than the day such notice is effective) after the occurrence of any of (x) a VWAP Trigger Event, (y) a Delisting Event or (z) unless otherwise specified therein, upon any Additional Termination Event. The Valuation Date notice will become effective immediately upon its delivery from the Seller to the Counterparty in accordance with the Forward Purchase Agreement.

On the Cash Settlement Payment Date, which is the tenth local business day immediately following the last day of the Valuation Period, the Seller will remit to the Counterparty a cash amount (the “Settlement Amount”) equal to (i) the Number of Shares as of the Valuation Date, multiplied by (ii) the difference of (a) the volume weighted daily VWAP Price over the Valuation Period, less (b) $0.50, and the Seller will not otherwise be required to return to the Counterparty any of the Prepayment Amount. In the event that the difference of (a) the volume weighted daily VWAP Price over the Valuation Period, less (b) $0.50, is equal to or less than $0, then the Settlement Amount shall be $0.

The Seller has agreed to waive any redemption rights with respect to any Recycled Shares in connection with the Business Combination only during the term of the Forward Purchase Agreement. Such waiver may reduce the number of Shares redeemed in connection with the Business Combination, and such reduction could alter the perception of the potential strength of the Business Combination. The 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, as amended.

The foregoing description of the Forward Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Forward Purchase Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 8.01

Other Events

Trust Disclosure Redemptions

As described in the proxy statement/prospectus included in the Registration Statement, ACAB provided holders of ACAB public shares sold in its initial public offering including shares issued upon the partial exercise of the underwriters’ over-allotment option (the “ACAB Public Shares”) with the opportunity to have all or a portion of their ACAB Public Shares redeemed for cash upon the closing of the Business Combination. As of November 8, 2024, holders of an aggregate of 80.55% or 436,019 ACAB Public Shares elected to exercise their right to redeem their ACAB Public Shares for a pro rata portion of the funds in the Trust Account. Based upon the current amount in the Trust Account, ACAB estimates that the per share redemption price, assuming estimated withdrawals from the Trust Account to pay franchise and income taxes owed by ACAB, as of November 8, 2024, will be approximately $11.28.

Important Information and Where to Find It

In connection with the Business Combination and the transactions contemplated thereby (the “Proposed Transactions”), ACAB has filed a Registration Statement on Form S-4, as amended, with the Securities and Exchange Commission (the “SEC”), which includes the Proxy Statement distributed to holders of ACAB’s common stock in connection with ACAB’s solicitation of proxies for the vote by ACAB’s stockholders with respect to the Proposed Transactions and other matters as described in the Registration Statement, a prospectus relating to the offer of the securities to be issued to stockholders in connection with the Proposed Transactions. ACAB has mailed a definitive proxy statement/prospectus to its stockholders. Investors and security holders and other interested parties are urged to read the proxy statement/prospectus, any amendments thereto and any other documents filed with the SEC carefully and in their entirety when they become available because they will contain important information about ACAB, Abpro and the Proposed Transactions. When available, investors and security holders may obtain free copies of the definitive proxy statement/prospectus and other documents filed with the SEC by ACAB through the website maintained by the SEC at http://www.sec.gov, or by directing a request to: Atlantic Coastal Acquisition Corp. II, 6 St Johns Lane, Floor 5 New York, NY 10013.

Participants in the Solicitation

ACAB and Abpro and their respective directors and certain of their respective executive officers and other members of management and employees may be considered participants in the solicitation of proxies with respect to the Proposed Transactions. Information about the directors and executive officers of ACAB is set forth in its Annual Report on Form 10-K for the fiscal year ended December 30, 2023 and the Registration Statement. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, is included in the Registration Statement and other relevant materials filed, or to be filed, with the SEC regarding the Proposed Transactions.

When available, these documents can be obtained free of charge from the sources indicated above.

No Offer or Solicitation

No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act.

These forward-looking statements should not be relied upon as representing ACAB’s or Abpro’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements.

Date:		November 7, 2024

To:		Atlantic Coastal Acquisition Corp. II, a Delaware corporation (“ACAB”), and Abpro Corporation, a Delaware Corporation (“Target”).

Address:		6 St Johns Lane, Floor 5 New York, NY 10013

From:		YA II PN, LTD., a Cayman Islands exempt limited company (“Seller”)

Re:		OTC Equity Prepaid Forward Transaction

The purpose of this agreement (this “Confirmation”) is to confirm the terms and conditions of the transaction (the “Transaction”) entered into between Seller, ACAB and Target on the Trade Date specified below. The term “Counterparty” refers to ACAB until the Business Combination (as defined below), then to Pubco (as defined below) following the Business Combination. In connection with the transactions contemplated by the BCA (as defined below), at the closing of the Business Combination, Abpro Merger Sub Corp., a Delaware corporation and a wholly-owned subsidiary of ACAB (“Merger Sub”), shall merge with and into Target, with Target surviving the merger as a wholly-owned subsidiary of ACAB (the “Merger”). In connection with the consummation of the Business Combination, ACAB will change its corporate name to “Abpro Holdings, Inc.” (“Pubco”) (the Merger and the other transactions contemplated by the BCA, collectively, the “Business Combination”). Certain terms of the Transaction shall be as set forth in this Confirmation, with additional terms as set forth in a pricing date notice (each, a “Pricing Date Notice”) in the form of Schedule A hereto. This Confirmation, together with the Pricing Date Notice(s), constitutes a “Confirmation” and the Transaction constitutes a separate “Transaction” as referred to in the ISDA Form (as defined below).

This Confirmation, together with the Pricing Date Notice(s), evidences a complete binding agreement between Seller, ACAB and Target as to the subject matter and terms of the Transaction to which this Confirmation relates and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

The 2006 ISDA Definitions (the “Swap Definitions”) and the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and with the Swap Definitions, the “Definitions”), each as published by the International Swaps and Derivatives Association, Inc., are incorporated into this Confirmation. If there is any inconsistency between the Definitions and this Confirmation, this Confirmation governs. If, in relation to the Transaction to which this Confirmation relates, there is any inconsistency between the ISDA Form, this Confirmation (including the Pricing Date Notice), the Swap Definitions and the Equity Definitions, the following will prevail for purposes of such Transaction in the order of precedence indicated: (i) this Confirmation (including the Pricing Date Notice(s)); (ii) the Equity Definitions; (iii) the Swap Definitions, and (iv) the ISDA Form.

This Confirmation, together with the Pricing Date Notice(s), shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002 Master Agreement (the “ISDA Form”) as if Seller, Target and Counterparty had executed an agreement in such form (but without any Schedule except as set forth herein under “Schedule Provisions”) on the Trade Date of the Transaction.

The terms of the particular Transaction to which this Confirmation relates are as follows:

General Terms


Type of Transaction:		Share Forward Transaction

Trade Date:		November 7, 2024

Pricing Date:		As specified in a Pricing Date Notice.

Effective Date:		One (T+2) Settlement Cycle following the Pricing Date.


Valuation Date:		The earliest to occur of (a) the date that is three months after the date of the closing of the Business Combination (the date of the closing of the Business Combination, the “Closing Date”) pursuant to the Business Combination Agreement, dated as of December 11, 2023 (as may be amended, supplemented or otherwise modified from time to time, the “BCA”), by and among ACAB, Merger Sub and Target, and (b) the date specified by Seller in a written notice to be delivered to Counterparty at Seller’s discretion (which Valuation Date shall not be earlier than the day such notice is effective) after the occurrence of any of (x) a VWAP Trigger Event, (y) a Delisting Event, or (z) unless otherwise specified therein, upon any Additional Termination Event.

VWAP Trigger Event:		An event that occurs if the VWAP Price, for any 20 trading days during a 30 consecutive trading day-period, is below $2.00 per Share.

VWAP Price:		For any scheduled trading day, the volume weighted average price per Share for such day as reported on the relevant Bloomberg Screen “ACAB <Equity> AQR SEC” (or any successor thereto), or if such price is not so reported on such trading day for any reason or is erroneous, the VWAP Price shall be as reasonably determined by the Calculation Agent.

Reset Price:		Initially $10.00, subject to reset immediately following the closing of trading on the last scheduled trading day of a week (the “Reset Week”) commencing with the first full week after the closing of the Business Combination to be the lowest of (a) the then current Reset Price, (b) $10.00 and (c) the VWAP Price of the Shares of the last 3 trading days of such Reset Week; provided that the Reset Price will also be reduced to the Dilutive Offering Price immediately upon the occurrence of a Dilutive Offering. In the event that the Counterparty in respect of the Shares engages in a stock split, a reverse stock split or pays dividends in the form of Shares (each, a “Dilutive Issuance”), the Reset Price shall be adjusted to reflect the effect of the Dilutive Issuance.

Dilutive Offering:		The Counterparty after the date hereof, sells, enters any agreement to sell or grants any right to reprice, or otherwise disposes of or issues (or announces any offer, sale, grant or any option to purchase or other disposition of) any Shares or any securities of the Counterparty or any of its respective subsidiaries (but for the avoidance of doubt, excluding any secondary transfers), which would entitle the holder thereof to acquire or sell on behalf of the Counterparty at any time Shares or other securities, including, without limitation, any debt, preferred stock, preference shares, right, option, warrant or other instrument that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive, Shares or other securities, at an effective price per share less than the then existing Reset Price (a “Dilutive Offering Price”); provided that, without limiting the foregoing, a Dilutive Offering (for the avoidance of doubt) shall, except with respect to the SEPA (as defined below), include any equity line of credit, at the market offering or other similar financing, and a Dilutive Offering shall not arise (i) as a result of the Standby Equity Purchase Agreement by and among Seller, ACAB and Target dated October 30, 2024 (the “SEPA”), (ii) from any grants, issuances or exercises of employee stock options or other equity awards under the Counterparty or Pubco’s equity compensation plans or Shares underlying warrants now outstanding or issued in connection with the Business Combination, (iii) as a result of any Shares or other securities issued in connection with (a) the Business Combination pursuant to the BCA and other transactions disclosed in the Definitive Proxy Statement/Prospectus related to the Business Combination or (b) costs and expenses incurred in connection with the Business Combination and the transactions related thereto, or (iv) from the issuance of any Shares or other securities convertible


		or exercisable for Shares issued pursuant to any other acquisition, merger or similar transaction by the Counterparty if the Shares or other securities issued in the transaction are restricted from transfer pursuant to a market standard lock-up agreement for a period of one year from the date of issuance. In the event that the Counterparty engages in a Variable Rate Transaction (other than with respect to the SEPA), a Dilutive Offering will have been deemed to have occurred if the lowest price contemplated under the transaction documentation of the Variable Rate Transaction is lower then the then-in-effect Reset Price and the price of such Dilutive Offering will be deemed to be the lowest price contemplated under the transaction documentation of the Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Counterparty or its subsidiaries issues or sells any convertible securities either (A) at a conversion, exercise or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the Shares at any time after the initial issuance of such convertible securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such convertible securities or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Counterparty, or the market for the Shares, other than pursuant to a customary “weighted average” anti-dilution provision.

Seller:		Seller.

Buyer:		Counterparty.

Counterparty shall provide notice to (i) Counterparty’s trustee of the entrance into this Confirmation no later than one Local Business Day following the date hereof, with copy to Seller and Seller’s outside legal counsel, and (ii) Seller and Seller’s outside legal counsel a final draft of the flow of funds from the Trust Account one Local Business Day prior to the closing of the Business Combination itemizing the Prepayment Amount due to Seller; provided that Seller shall be invited and permitted to attend any closing call in connection with the Business Combination.

Optional Early Termination:		From time to time and on any date following the Business Combination (any such date, an “OET Date”) and subject to the terms and conditions below, Seller may, in its absolute discretion, terminate the Transaction in whole or in part by providing written notice to 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”)); provided that “Terminated Shares” includes only such quantity of Shares by which the Number of Shares is to be reduced and included in an OET Notice and does not include any other Shares, whether or not sold, which Shares will not be included in any OET Notice or included in the definition, or when calculating the number, of Terminated Shares.

The remainder of the Transaction, if any, shall continue in accordance with its terms.

If, after following the procedures and within the specified time frames set forth above, a binding determination is not achieved, the original determination of the Calculation Agent or Determining Party, as applicable, shall apply. Following any adjustment, determination or calculation by the Calculation Agent hereunder, upon a written request by Counterparty (which may be by email), the Calculation Agent will promptly (but in any event within five Exchange Business Days) provide to Counterparty by email to the email address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such adjustment, determination


		or calculation (including any quotations, market data or information from internal or external sources, and any assumptions used in making such adjustment, determination or calculation), it being understood that in no event will the Calculation Agent be obligated to share with Counterparty any proprietary or confidential data or information or any proprietary or confidential models used by it in making such adjustment, determination or calculation or any information that is subject to an obligation not to disclose such information.

Other Provisions.

(a) Rule 10b-5.

(i)

Counterparty represents and warrants to Seller that Counterparty is not entering into the Transaction to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) for the purpose of inducing the purchase or sale of such securities or otherwise in violation of the Exchange Act, and Counterparty represents and warrants to Seller that Counterparty has not entered into or altered, and agrees that Counterparty will not enter into or alter, any corresponding or hedging transaction or position with respect to the Shares.

(ii)

Counterparty agrees that it will not seek to control or influence Seller’s decision to make any “purchases or sales” under the Transaction, including, without limitation, Seller’s decision to enter into any hedging transactions. Counterparty represents and warrants that it has consulted with its own advisors as to the legal aspects of its adoption and implementation of this Confirmation and the Transaction under the federal securities laws, including without limitation, the prohibitions on manipulative and deceptive devices under the Exchange Act.

(iii)

Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this Confirmation must be effected in accordance with the requirements for the amendment or termination of a written trading plan for trading securities. Without limiting the generality of the foregoing, Counterparty acknowledges and agrees that any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws, including without limitation the prohibition on manipulative and deceptive devises under the Exchange Act and no such amendment, modification or waiver shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares.

(b)

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares (other than in connection with a Counterparty equity compensation program (e.g., to fund taxes in connection with vested RSUs)), promptly give Seller a written notice of such repurchase (a “Repurchase Notice”), if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than the number of Shares outstanding that would result in the percentage of total Shares outstanding represented by the number of Shares underlying the Transaction increasing by 0.10% (in the case of the first such notice) or (ii) thereafter more than the number of Shares that would need to be repurchased to result in the percentage of total Shares outstanding represented by the number of Shares underlying the Transaction increasing by a further 0.10% less than the number of Shares included in the immediately preceding Repurchase Notice; provided that Counterparty agrees that this information does not constitute material non-public information; provided further if this information shall be material non-public information, it shall publicly disclosed immediately. Counterparty agrees to indemnify and hold harmless Seller and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Seller’s hedging activities as a consequence of remaining or becoming a Section 16 “insider” following the closing of the Business Combination, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable and documented out-of-pocket expenses (including reasonable and documented attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Seller with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within thirty days, upon written request, each of such Indemnified Persons for any reasonable and documented legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing; provided, however, for the avoidance of doubt, Counterparty has no indemnification or other obligations with respect to Seller becoming a Section 16 “insider” prior to the closing of the Business Combination. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Seller with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall

contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

(c)

Transfer or Assignment. The rights and duties under this Confirmation may not be transferred or assigned by any party hereto without the prior written consent of the other party, such consent not to be unreasonably withheld, subject to the immediately following sentence. If at any time following the closing of the Business Combination at which (A) the Section 16 Percentage exceeds 9.9%, or (B) the Share Amount exceeds the Applicable Share Limit, if any applies (any such condition described in clause (A) or (B), an “Excess Ownership Position”), Seller is unable to effect a transfer or assignment of a portion of the Transaction to a third party on pricing terms reasonably acceptable to Seller and within a time period reasonably acceptable to Seller such that no Excess Ownership Position exists, then Seller may designate any Local Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Seller so designates an Early Termination Date with respect to a portion of the Transaction, a portion of the Shares with respect to the Transaction shall be delivered to Counterparty as if the Early Termination Date was the Valuation Date in respect of a Transaction having terms identical to the Transaction and a Number of Shares equal to the number of Shares underlying the Terminated Portion. The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, as determined by Seller, (A) the numerator of which is the number of Shares that Seller and each person subject to aggregation of Shares with Seller under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) of the Exchange Act) with Seller directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) (the “Seller Group” ) and (B) the denominator of which is the number of Shares outstanding.

The “Share Amount” as of any day is the number of Shares that Seller and any person whose ownership position would be aggregated with that of Seller and any group (however designated) of which Seller is a member (Seller or any such person or group, a “Seller Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Seller in its sole discretion.

The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting (other than on Schedule 13D or 13G) or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Seller Person, or could result in an adverse effect on a Seller Person, under any Applicable Restriction, as determined by Seller in its sole discretion, minus (B) 0.1% of the number of Shares outstanding.

(d)

Indemnification. Counterparty agrees to indemnify and hold harmless each Indemnified Person from and against any and all losses (but not including financial losses to an Indemnified Person relating to the economic terms of the Transaction provided that the Counterparty performs its obligations under this Confirmation in accordance with its terms), claims, damages and liabilities (or actions in respect thereof) expenses (including reasonable attorney’s fees), joint or several, incurred by or asserted against such Indemnified Person arising out of, in connection with, or relating to, and to reimburse, within thirty days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, whether arising out of any action between any of the Indemnified Parties and the Counterparty or between any of the Indemnified Parties and any third party, or otherwise) to which they or any of them may become subject under the Securities Act, the Exchange Act or any other statute or at common law or otherwise or under the laws of foreign countries, arising out of or based upon the Transaction, including the execution or delivery of this Confirmation, the performance by Counterparty of its obligations under the Transaction, any material breach of any covenant, representation or warranty made by Counterparty or Target in this Confirmation or the ISDA Form, regulatory filings and submissions made by or on behalf of the Counterparty related to the Transaction (other than as relates

to any information provided in writing by or on behalf of Seller or its affiliates), or the consummation of the transactions contemplated hereby, including any untrue statement or alleged untrue statement of a material fact contained in any registration statement, press release, filings or other document, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Counterparty will not be liable under the foregoing indemnification provision to the extent that any loss, claim, damage, liability or expense is related to the manner in which Seller sells, or arising out of any sales by Seller of, any Shares, including the Recycled Shares or found in a nonappealable judgment by a court of competent jurisdiction to have resulted from Seller’s material breach of any covenant, representation or other obligation in this Confirmation or the ISDA Form or from Seller’s willful misconduct, bad faith or gross negligence in performing the services that are subject of the Transaction. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or insufficient to hold harmless any Indemnified Person, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Person as a result of such loss, claim, damage or liability. In addition (and in addition to any other Reimbursement of Legal Fees and other Expenses contemplated by this Confirmation), Counterparty will reimburse any Indemnified Person for all reasonable, out-of-pocket, expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Person is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. Counterparty also agrees that no Indemnified Person shall have any liability to Counterparty or any person asserting claims on behalf of or in right of Counterparty in connection with or as a result of any matter referred to in this Confirmation except to the extent that any losses, claims, damages, liabilities or expenses incurred by Counterparty result from such Indemnified Person’s breach of any covenant, representation or other obligation in this Confirmation or the ISDA Form or from the gross negligence, willful misconduct or bad faith of the Indemnified Person or breach of any U.S. federal or state securities laws or the rules, regulations or applicable interpretations of the Commission. The provisions of this paragraph shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and/or delegation of the Transaction made pursuant to the ISDA Form or this Confirmation shall inure to the benefit of any permitted assignee of Seller.

(f)

Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual waivers and certifications provided herein.

(g)

Attorney and Other Fees. Subject to clause (d) Indemnification (above), in the event of any legal action initiated by any party arising under or out of, in connection with or in respect of, this Confirmation or the Transaction, the prevailing party shall be entitled to reasonable and documented attorneys’ fees, costs and expenses incurred in such action, as determined and fixed by the court.

(i)

Securities Contract; Swap Agreement. The parties hereto intend for (i) the Transaction to be (a) a “securities contract” as defined in the Bankruptcy Code, in which case each payment and delivery made pursuant to the Transaction is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment,” within the meaning of Section 546 of the Bankruptcy Code, and (b) a “swap agreement” as defined in the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code and a “payment or other transfer of property” within the meaning of Sections 362 and 546 of the Bankruptcy Code, and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s right to liquidate, terminate and accelerate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the ISDA Form with respect to the other party to constitute a “contractual right” as described in the Bankruptcy Code, and (iii) each payment and delivery of cash, securities or other property hereunder to otherwise constitute a “margin payment” or “settlement payment” and a “transfer” as defined in the Bankruptcy Code.

Most Favored Nation. In the event the Counterparty enters into one or more other forward share purchase agreements before or after the execution of this Confirmation, the Counterparty represents that the terms of such other agreements, considered in the aggregate, will not be materially more favorable to such other investors thereunder than the terms of this Confirmation are in respect of Seller. In the event that another investor is afforded any such more favorable terms than Seller, the Counterparty shall promptly inform Seller of such more favorable terms in writing, and Seller shall have the right to elect to amend this Confirmation and to the extent required to ensure that the terms of this Confirmation are as favorable to Seller as the terms of such other agreements are to such other investors, in which case the parties hereto shall promptly amend this Confirmation to effect the same.
