Sachem Capital Corp.

(i) An Option or SAR shall be exercisable at such times and under such conditions as determined by the Committee under the terms of the Plan and specified in the Award Agreement.

(ii) An Option or SAR shall be deemed exercised when written notice of such exercise has been given to the Company (or a broker pursuant to Section 7(b)(vi)) in accordance with the

​

terms of the Award by the Participant and, if applicable, full payment for the Shares with respect to which the Option or SAR is exercised has been made (together with applicable tax withholding).

(b)Exercise Following Termination of Continuous Service. If a Participant’s Continuous Service terminates, all or any portion of the Participant’s Options or SARs that were vested at the Termination Date (including any portion thereof that vested as a result of such termination) may be exercised during the applicable Post-Termination Exercise Period. Except as otherwise determined by the Committee or as set forth in the Participant’s Award Agreement, if the Participant’s Options or SARs are unvested on the Termination Date (and do not vest as a result of such termination), or if the vested portion of the Participant’s Options or SARs is not exercised within the applicable Post-Termination Exercise Period, the Options and SARs shall terminate.

(i)Termination for Cause. Except as otherwise determined by the Committee or set forth in the Participant’s Award Agreement, upon the termination of the Participant’s Continuous Service for Cause, the Participant’s right to exercise an Option or SAR (whether vested or unvested) shall terminate concurrently with the termination of the Participant’s Continuous Service.

(ii)Change in Status. If a Participant’s status changes from Employee to Consultant or non-Employee Director, the Employee’s Incentive Stock Option shall automatically become a Non-Qualified Stock Option on the day that is three months and one day following such change of status.

(iii)Termination Due to Disability. If a Participant’s Continuous Service terminates as a result of Disability, if such Disability is not a “permanent and total disability” as such term is defined in Section 22(e)(3) of the Code, in the case of an Incentive Stock Option, such Incentive Stock Option shall automatically become a Non-Qualified Stock Option on the day that is three months and one day following such termination.

9. Conditions upon Issuance of Shares. If the Committee determines that the delivery of Shares with respect to an Award is or may be unlawful under Applicable Laws, the vesting or right to exercise an Award or to otherwise receive Shares with respect to an Award shall be suspended until the Committee determines that such delivery is lawful. An Incentive Stock Option may not be exercised until the Plan has been approved by the shareholders of the Company. The Company shall have no obligation to effect any registration or qualification of the Shares under Applicable Laws. A Participant’s right to exercise an Award may be suspended for a limited period of time if the Committee determines that such suspension is administratively necessary or desirable.

10. Adjustments upon Changes in Capitalization. Subject to any required action by the shareholders of the Company, Applicable Laws and Section 11, (i) the number and kind of Shares or other securities or property covered by each outstanding Award, (ii) the number and kind of Shares that have been authorized for issuance under the Plan, (iii) the exercise price, base amount or purchase price of each outstanding Award, and (iv) any other terms that the Committee determines require adjustment, shall be proportionately adjusted for: (A) any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, recapitalization, combination or reclassification of the Shares, or similar transaction affecting the Shares; (B) any other increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; (C) any other transaction with respect to the Shares, including any distribution of cash, securities or other property to shareholders (other than a normal cash dividend), a corporate merger, consolidation, acquisition of property or stock, separation (including a spin-off or other distribution of stock or property), reorganization, liquidation (whether partial or complete), a “corporate transaction” as defined in Section 424 of the Code or any similar transaction; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration;” or (D) any change in the capital structure or business of the Company or other corporate transaction or event that would be considered an “equity restructuring” within the meaning of ASC 718 and, in each case, that would result in an additional compensation expense to the Company pursuant to the provisions of ASC Topic 718, if adjustments to Awards with respect to such event were discretionary or otherwise not required. Any such adjustments to outstanding Awards shall be effected in a manner that is intended to preclude the enlargement or diminution of rights and benefits under such Awards. Except as the Committee determines, no issuance by the Company of shares of any class, or securities

​

convertible into shares of any class, shall affect, and no adjustment by reason hereof shall be made with respect to, the number or price of Shares subject to an Award.

11. Change in Control. Subject to Section 10 and except as otherwise provided in an Award Agreement, employment or similar agreement or in the definitive Change in Control transaction agreement, in the event of a Change in Control, the Awards shall be treated as follows:

(a) If the Company is the surviving entity (in which case the Awards will continue) or if the Company is not the surviving entity, but the surviving entity (or a parent entity thereof) assumes an Award or substitutes for an Award another award relating to the stock of such surviving entity (or parent thereof), such awards (the “Continued, Assumed or Substituted Awards”) shall remain governed by their respective terms; provided, that (A) if, as of the Change in Control, the Awards are subject to vesting conditions relating to items or events other than Continuous Service (e.g., performance-based vesting conditions), such vesting conditions shall be deemed to have been satisfied at the “target” ​(or term of similar import) performance level (or, if the applicable performance period has been completed as of the date of the Change in Control, at the performance level achieved based on actual performance) and the Continued, Assumed or Substituted Awards shall remain subject to any vesting conditions based on Continuous Service, without proration, and (B) if on, or within 24 months following, the date of the Change in Control, the Participant’s Continuous Service is terminated by the Company or a Related Entity without Cause, the Continued, Assumed or Substituted Awards held by the Participant that were not then vested (and, with respect to Options and SARs, exercisable) shall immediately become fully vested and, if applicable, exercisable.

(b) If the Company is not the surviving entity and the surviving entity (or a parent entity thereof) does not assume or substitute Awards, the holders of such Awards shall be entitled to the benefits set forth in Section 11(a) as of the date of the Change in Control, to the same extent as if the holder’s Continuous Service had been terminated by the Company without Cause as of the date of the Change in Control; provided, that, to the extent any Award constitutes deferred compensation for purposes of Section 409A, if the settlement or other payment event resulting from the vesting of such Award pursuant to this Section 11(b) would not be permitted by Section 409A, such Award shall vest pursuant to this Section 11(b), but the settlement or other payment event with respect to such Award shall not be accelerated and shall instead occur when it would have occurred had the Award been Continued, Assumed or Substituted pursuant to Section 11(a) (or on such earlier date as is permitted under Section 409A). The Committee may provide that each Award that is vested (or vests) as of the Change in Control shall be canceled in exchange for a payment in an amount equal to (A) the Fair Market Value per Share subject to the Award immediately prior to the Change in Control over the exercise or base price (if any) per Share subject to the Award multiplied by (B) the number of Shares granted under the Award. For avoidance of doubt, if the Fair Market Value per Share subject to an Option or SAR immediately prior to the Change in Control is less than the exercise or base price per Share of such Award, such Awards shall be cancelled for no consideration.

(c) For the purposes of this Section 11, an Award shall be considered assumed or substituted for if immediately following the Change in Control the award is of substantially equal value, with the determination of such substantial equality of value being made by the Committee before the Change in Control.

12. Effective Date and Term of Plan. The Plan shall become effective upon its approval by the shareholders of the Company (the “Effective Date”). Unless terminated earlier by the Board pursuant to Section 13(a), the Plan shall terminate on the tenth anniversary of the earlier of the date that the Plan is adopted or the date of shareholder approval. No grants of Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is approved by the Board.

13. Amendment, Suspension or Termination of the Plan or Awards.

(a) The Board may at any time amend, suspend or terminate the Plan. To the extent necessary to comply with Applicable Laws, the Company shall obtain shareholder approval of any Plan amendment required to be subject to shareholder approval.

​

(b) No Award may be granted during any suspension of the Plan or after termination of the Plan.

(c) No amendment, suspension or termination of the Plan or any Award shall materially adversely affect the Participant’s rights under an Award without the Participant’s written consent; provided, however, that an amendment or modification that (i) may cause an Incentive Stock Option to become a Non-Qualified Stock Option or (ii) the Committee considers, in its sole discretion, necessary or advisable to comply with, take into account or otherwise respond to Applicable Laws, shall not be treated as materially adversely affecting the Participant’s right under an outstanding Award.

14. Clawback. The Plan and all Awards granted hereunder are subject to any written clawback policies that the Company, with the approval of the Board or an authorized committee thereof, may adopt or amend either prior to or following the Effective Date, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the United States Securities and Exchange Commission and that the Company determines should apply to Awards. Any such policy may subject a Participant’s Awards and amounts paid or realized with respect to Awards to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Company’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy.

15. Limitation of Liability. The Company is under no duty to ensure that Shares may legally be delivered under the Plan, and shall have no liability in the event such delivery of Shares may not be made.

16. No Effect on Terms of Employment/Consulting Relationship. The Plan shall not confer upon any Participant any right with respect to the Participant’s Continuous Service, nor shall it interfere in any way with the Participant’s right or the right of the Company or any Related Entity to terminate the Participant’s Continuous Service at any time, with or without Cause, and with or without notice.

17. No Effect on Retirement and Other Benefit Plans. Except as specifically provided in a compensation or benefit plan, program or arrangement of the Company or a Related Entity, Awards shall not be deemed compensation for purposes of such plans, programs or arrangements. The Plan is not a “pension plan” or “welfare plan” under the Employee Retirement Income Security Act of 1974.

18. Unfunded Obligation. A Participant shall have the status of general unsecured creditors of the Company. Any amounts payable to Participants pursuant to the Plan or an Award shall be unfunded and unsecured obligations for all purposes, including Title I of the Employee Retirement Income Security Act of 1974. Neither the Company nor any Related Entity shall be required to segregate any monies from its general funds, to create any trusts, or to establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, that the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not create or constitute a trust or fiduciary relationship between the Committee, the Company or any Related Entity and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors in any assets of the Company or a Related Entity. A Participant shall have no claim against the Company or any Related Entity for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan.

19. Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and procedures, as in effect from time to time.

20. Construction. The following rules of construction shall apply to the Plan and Award Agreements. Captions and titles are for convenience only and shall not affect the meaning or interpretation of any provision of the Plan or Award Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the word “or” is not intended to be exclusive, unless the context clearly requires otherwise. The words “include,” “includes” or “including” shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. The words “writing” and “written” and comparable words refer to printing, typing and other means of reproducing words (including electronic media) in a visible form. Any reference to any federal, state or other statute or law shall be deemed also to refer to such statute or law as

​

amended, and to all rules and regulations promulgated thereunder. References to “stockholders” shall be deemed to refer to “shareholders” to the extent required by Applicable Laws. References to the Company or any Related Entity shall include such entity’s successors.

21. Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board, the submission of the Plan to the shareholders of the Company for approval nor any provision of the Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable. Nothing contained in the Plan shall be construed to prevent the Company or a Related Entity from taking any corporate action which is deemed by the Company or such Related Entity to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan. No Employee, beneficiary or other person shall have any claim against the Company or any Related Entity as a result of any such action.

22. Governing Law. Except as otherwise provided in an Award Agreement, the Plan, the Award Agreements and any other agreements or arrangements relating to Awards shall be interpreted and construed in accordance with the laws of the State of New York, without regard to the conflicts of laws rules of such state, to the extent not preempted by federal law. If any provision of the Plan, the Award Agreements or any other agreements or arrangements relating to Awards is determined to be illegal or unenforceable, such provision shall be enforced to the fullest extent allowed by Applicable Laws and the other provisions shall nevertheless remain effective and shall remain enforceable.

23. Jurisdiction; Choice of Forum. Any suit, action or proceeding relating to or arising out of this Plan or any Award Agreement, or any judgment entered by any court of competent jurisdiction in respect thereof (a “Proceeding”), shall be brought only in the federal or state courts located in the State of Connecticut. The Company and each Participant shall irrevocably and unconditionally (a) consent and submit to the exclusive jurisdiction of the courts of the State of Connecticut, the United States District Court for the District of Connecticut, and appellate courts having jurisdiction of appeals from any of the foregoing, and agree that all claims in respect of any such Proceeding shall be heard and determined in such Connecticut court or, to the extent permitted by law, in such federal court, (b) waive any objection that the Company and each Participant may now or thereafter have to the venue or jurisdiction for any such Proceeding in any such court or that such Proceeding was brought in an inconvenient forum and agree not to plead or claim the same, and (c) agree that service of process in any such Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party, in the case of a Participant, at the Participant’s address shown in the books and records of the Company or, in the case of the Company, at the Company’s principal offices, attention Chief Executive Officer.
