STOCK OPTION AWARD AGREEMENT

UNDER THE

KEYSTONE DENTAL HOLDINGS, INC.

2023 EQUITY INCENTIVE PLAN

According to the Capital Gains Tax Route of Section 102

THIS STOCK OPTION AWARD AGREEMENT (this “Agreement”) is made between KEYSTONE DENTAL HOLDINGS, INC., a Delaware corporation (the “Company”), and [__________] (the “Grantee”).

WHEREAS, the Company maintains the KEYSTONE DENTAL HOLDINGS, INC. 2023 Equity Incentive Plan (the “Master Plan”) and the Israeli Sub-Plan (the “Sub-Plan, and together with the Master Plan, the “Plan”) for the benefit of Employees, Directors and Consultants of the Company and its subsidiaries; and

WHEREAS, the Plan permits the award of Stock Options to purchase shares of the Company’s Common Stock, subject to the terms of the Plan and the Sub-Plan for Israeli Participants; and

WHEREAS, to compensate the Grantee for his/her service to the Company and its subsidiaries and to further align the Grantee’s personal financial interests with those of the Company’s stockholders, the Company wishes to award the Grantee (which award may be granted to the Trustee (as defined below) for the benefit of the Grantee, as discussed below) an option to purchase [_____] shares of the Company’s Common Stock, subject to the restrictions and on the terms and conditions contained in the Plan and this Agreement;

NOW, THEREFORE, in consideration of these premises and the agreements set forth herein and intending to be legally bound hereby, the parties agree as follows:

1. Award of Option. This Agreement evidences the grant to the Grantee (or the Trustee (as defined below) for the benefit of the Grantee) of an option (the “Option”) to purchase [_____] shares of the Company’s Common Stock (the “Option Shares”). The Option is subject to the terms set forth herein, and in all respects is subject to the terms and provisions of the Plan, which terms and provisions are incorporated herein by this reference. Except as otherwise specified herein or unless the context herein requires otherwise, the terms defined in the Plan will have the same meanings herein.

The Option Shares will be deposited with a trustee approved by the Israeli Tax Authority for this purpose (the “Trustee”), which will hold the Option Shares in trust on behalf of the Grantee, all as set forth in Section 3 below (all references to a grant of Option or issuance of Shares to the Grantee, shall mean an issuance to the Trustee for the benefit of the Grantee.

2. Nature of the Option. This Agreement is subject to the provisions of Section 102 of the Income Tax Ordinance [New version], 1961 (the “Ordinance” and “Section 102”, respectively), as well as the Income Tax Rules (Tax Relief in Issuance of Shares to Employees), 2003 (the “102 Rules”), promulgated thereunder.

Accordingly, the Company elected the Capital Gains Route in Section 102(b)(2) of the Ordinance (the “Capital Gains Route”) for the purpose of the taxation of Participant’s income from the Option. In general, taxable income that should be attributed to the Grantee as a result of the grant of the option will be tax-free on the date of grant, but will be taxed on the sale of Shares issued upon exercise of the option or any portion of it (i.e., the Shares) or transfer of the Shares from the Trustee (a “Transfer”). In accordance with the Capital Gains Route, if the Option or the Shares are held in trust by the Trustee for the applicable period of time (see Section (4) below), currently two years from the date of grant of the Option (subject to its timely deposited with a Trustee) (the “Minimum Trust Period”), gains derived from the sale of Shares shall be classified as capital gains and taxed at a rate of only 25%.

At the time of sale of the Shares or a Transfer, the Grantee shall be subject to tax, which will be calculated, in general, according to difference between (a) the market price (or the actual sale price) of the Shares at such time, and (b) the Exercise Price¹. Such tax shall be withheld at source by the Israeli subsidiary of the Company, in accordance with the provisions of the 102 Rules, and the transfer of Shares to the Grantee is conditioned upon the payment of such tax.

The Grantee shall not be entitled to sell the Shares or to execute a Transfer prior to the lapse of the Minimum Trust Period. Furthermore, any and all rights issued in respect of the Shares, including bonus shares but excluding cash dividends (“Rights”), shall be deposited with the Trustee and held thereby until the lapse of the Minimum Trust Period, and such Rights shall be subject to the Capital Gains Route. Notwithstanding the aforesaid, the Grantee may sell the Shares or Rights or execute a Transfer prior to the lapse of the Minimum Trust Period, provided, however, that tax is withheld at source by the Company (or the Grantee’s employer) in accordance with the 102 Rules. In such case, the Grantee’s gains shall be classified as ordinary income and he or she shall be subject to tax on such income at marginal tax rates (including “High Income Tax”/Surtax, if applicable) plus social security and national health insurance payment.

3. Trust. To secure performance of tax law requirements, the Option awarded to the Grantee according to this Agreement will be held in trust by the Trustee (which Trustee was approved for this purpose by the Israeli Tax Authority), which shall release it to the Grantee only upon full compliance with the legal requirements and the terms of the Plan. For this purpose, a Trust Deed was signed between the Israeli subsidiary of the Company and the Trustee, a copy of which is attached hereto as Exhibit A. The conditions of the Trust Deed apply to the Option awarded to the Grantee, and we recommend that you carefully read the provisions of the Trust Deed.

4. Date of Grant; Term of Option. The Option was granted on ___________, __, 202_ (the “Effective Date”) and may not be exercised later than the tenth anniversary of that date.

¹  The above tax description is a general summary only and does not refer to expenses involved with the exercise of option and sale of Shares or changes in the Israeli Consumer Price Index or the currency exchange ratio, which may impact the final tax calculation.

Such written notice shall be signed by the Grantee, delivered in person or by certified mail to the Secretary of the Company or the Trustee or such other person as may be designated by the Company and accompanied by payment of the Exercise Price and an amount equal to any required tax withholding, and shall be effective upon receipt by the Company. Payment may be made in any manner set forth in Section 6(c) of the Master Plan, subject to compliance with the provisions of Section 102 and the approval of the ITA (if applicable), provided that the Administrator has the power to remove or limit any such forms of consideration for exercising an Option except for the payment of cash at any time in its sole discretion.

(c) Partial Exercise. The Option may be exercised in whole or in part; provided, however, that any exercise may apply only with respect to a whole number of Option Shares.

(d) Restrictions on Exercise.

The Board may from time to time modify the terms of this Option or impose additional conditions on the exercise of this Option as it deems necessary or appropriate to facilitate compliance with any law, regulation or exchange listing requirement. As a further condition to the exercise of the Option, the Company may require the Grantee to make any representation or warranty as may be required by or advisable under any applicable law or regulation.

7. Investment Representations. The Grantee represents and warrants to the Company that he or she is acquiring the Option (and upon exercise of the Option, will be acquiring the Option Shares) for investment for his or her own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof.

8. Non-Transferability of Option. The Option may not be sold, pledged, assigned, hypothecated, gifted, transferred or disposed of in any manner either voluntarily or involuntarily by operation of law, other than by will or by the laws of descent or distribution.

The Grantee understands that he or she (and not the Company) will be responsible for his or her own tax liabilities arising in connection with this Option.
