<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in; color: #231F20">In the event that any federal,
state, or local income taxes, employment taxes, Federal Insurance Contributions Act withholdings or other amounts are required by applicable
law or governmental regulation to be withheld from the Participant&rsquo;s salary, wages or other remuneration in connection with the
issuance of a Stock Right or Shares under the Plan or for any other reason required by law, the Company may withhold from the Participant&rsquo;s
compensation, if any, or may require that the Participant advance in cash to the Company, or to any Affiliate of the Company which employs
or employed the Participant, up to the statutory maximum amount of such withholdings unless a different withholding arrangement, including
the use of shares of the Company&rsquo;s Common Stock or a promissory note, is authorized by the Administrator (and permitted by law).
For purposes hereof, the fair market value of the shares withheld for purposes of payroll withholding shall be determined in the manner
set forth under the definition of Fair Market Value provided in Paragraph 1 above, as of the most recent practicable date prior to the
date of exercise. If the Fair Market Value of the shares withheld is less than the amount of payroll withholdings required, the Participant
may be required to advance the difference in cash to the Company or the Affiliate employer.</P>

must agree to notify the Company in writing immediately after the Employee makes a Disqualifying Disposition of any Shares acquired pursuant
to the exercise of an ISO. A Disqualifying Disposition is defined in Section 424(c) of the Code and includes any disposition (including
any sale or gift) of such Shares before the later of (a) two years after the date the Employee was granted the ISO, or (b) one year after
the date the Employee acquired Shares by exercising the ISO, except as otherwise provided in Section 424(c) of the Code. If the Employee
has died before such Shares are sold, these holding period requirements do not apply and no Disqualifying Disposition can occur thereafter.</P>

shareholders of the Company. The Plan may also be amended by the Administrator; provided that any amendment approved by the Administrator
which the Administrator determines is of a scope that requires shareholder approval shall be subject to obtaining such shareholder approval
including, without limitation, to the extent necessary to qualify any or all outstanding Stock Rights granted under the Plan or Stock
Rights to be granted under the Plan for favorable federal income tax treatment as may be afforded ISOs under Section 422 of the Code and
to the extent necessary to qualify the Shares issuable under the Plan for listing on any national securities exchange or quotation in
any national automated quotation system of securities dealers. Other than as set forth in Paragraph 25 of the Plan, the Administrator
may not, without shareholder approval, reduce the exercise price of an Option or take any other action that is considered a direct or
indirect &ldquo;repricing&rdquo; for purposes of the shareholder approval rules of the applicable securities exchange or inter-dealer
quotation system on which the Shares are listed, including any other action that is treated as a repricing under generally accepted accounting
principles. Any modification or amendment of the Plan shall not, without the consent of a Participant, adversely affect his or her rights
under a Stock Right previously granted to him or her, unless such amendment is required by applicable law or necessary to preserve the
economic value of such Stock Right. With the consent of the Participant affected, the Administrator may amend outstanding Agreements in
a manner which may be adverse to the Participant but which is not inconsistent with the Plan. In the discretion of the Administrator,
outstanding Agreements may be amended by the Administrator in a manner which is not adverse to the Participant. Nothing in this Paragraph
31 shall limit the Administrator&rsquo;s authority to take any action permitted pursuant to Paragraph 25.</P>

(the "Registrant") stated above consists of additional shares of common stock available for issuance under the 2026 Second Amended and Restated Equity Incentive Plan (the "Plan"), as approved by the Registrant's stockholders at the Registrant's annual meeting of stockholders on June 16, 2026. The maximum number of shares which may be sold upon the exercise of options or issuance of stock-based awards granted under the Plan is subject to adjustment in accordance with certain anti-dilution and other provisions of the Plan. Accordingly, pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), this registration statement covers, in addition to the number of shares stated above, an indeterminate number of shares which may be subject to grant or otherwise issuable after the operation of any such anti-dilution and other provisions.

Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and Rule 457(h) promulgated under the Securities Act. The offering price per share and the aggregate offering price for shares reserved for future grant or issuance under the Plan are based on the average of the high and the low price of Registrant's common stock as reported on The Nasdaq Capital Market as of a date (June 11, 2026) within five business days prior to filing this Registration Statement.</ix:nonNumeric>

<td class="text">The number of shares of common stock, par value $0.0001 per share ("Common Stock"), of SELLAS Life Sciences Group, Inc. (the "Registrant") stated above consists of additional shares of common stock available for issuance under the 2026 Second Amended and Restated Equity Incentive Plan (the "Plan"), as approved by the Registrant's stockholders at the Registrant's annual meeting of stockholders on June 16, 2026. The maximum number of shares which may be sold upon the exercise of options or issuance of stock-based awards granted under the Plan is subject to adjustment in accordance with certain anti-dilution and other provisions of the Plan. Accordingly, pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), this registration statement covers, in addition to the number of shares stated above, an indeterminate number of shares which may be subject to grant or otherwise issuable after the operation of any such anti-dilution and other provisions.

Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and Rule 457(h) promulgated under the Securities Act. The offering price per share and the aggregate offering price for shares reserved for future grant or issuance under the Plan are based on the average of the high and the low price of Registrant's common stock as reported on The Nasdaq Capital Market as of a date (June 11, 2026) within five business days prior to filing this Registration Statement.<span></span>

(the "Registrant") stated above consists of additional shares of common stock available for issuance under the 2026 Second Amended and Restated Equity Incentive Plan (the "Plan"), as approved by the Registrant's stockholders at the Registrant's annual meeting of stockholders on June 16, 2026. The maximum number of shares which may be sold upon the exercise of options or issuance of stock-based awards granted under the Plan is subject to adjustment in accordance with certain anti-dilution and other provisions of the Plan. Accordingly, pursuant to Rule 416 under the Securities Act of 1933, as amended (the "Securities Act"), this registration statement covers, in addition to the number of shares stated above, an indeterminate number of shares which may be subject to grant or otherwise issuable after the operation of any such anti-dilution and other provisions.

Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and Rule 457(h) promulgated under the Securities Act. The offering price per share and the aggregate offering price for shares reserved for future grant or issuance under the Plan are based on the average of the high and the low price of Registrant's common stock as reported on The Nasdaq Capital Market as of a date (June 11, 2026) within five business days prior to filing this Registration Statement.</ffd:OfferingNote>
