Share Exchange:

As detailed in Note 1, as part of the Recapitalization Transaction on October 28, 2019, the Company issued 15,069,058 shares of Common Stock in exchange for approximately 65% of the issued and outstanding ordinary shares and all the preferred shares of BiomX Israel. The number of shares prior to the Recapitalization Transaction has been retroactively adjusted based on the equivalent number of shares received by the accounting acquirer in the Recapitalization Transaction.

In addition, the Company also agreed to issue the following number of additional shares of Common Stock, in the aggregate, to Chardan Healthcare Acquisition Corp. shareholders on a pro rata basis, subject to the Company's achievement of the conditions specified below following the Recapitalization Transaction (all with respect to the Company's shares of Common Stock traded on NYSE American):

Preferred Stock:

The Company is authorized to issue 1,000,000 shares of preferred stock with a par value of $0.0001 per share with such designation, rights and preferences as may be determined from time to time by the Company's Board of Directors.

In 2015, the Board of Directors of BiomX Israel approved a plan for the allocation of options to employees, service providers and officers (the "2015 Plan"). The options represented a right to purchase one ordinary share of BiomX Israel in consideration of the payment of an exercise price. The options were granted in accordance with the "capital gains route" under section 102 and section 3(i) of the Israeli Income Tax Ordinance and section 409A of the Israeli Internal Revenue Code.

The original 2015 Plan was adjusted following the Recapitalization Transaction on October 28, 2019 such that each outstanding option entitles its holder to purchase one share of Common Stock of the Company. As a result, the number of options and exercise price per share were adjusted in a technical manner such that there was no change in the fair value of the awards under the adjusted 2015 Plan. The number of outstanding options and exercise prices in this Note have been restated to reflect the adjusted 2015 Plan. As of September 30, 2020, there are no shares remaining for issuance under the 2015 Plan.

During 2019, the Board approved the grant of 704,669 options to 22 employees and 79,630 options to two consultants, without consideration. 527,716 of the options granted are to the executive officers of the Company. These options were granted under the 2015 Plan.

During 2019, 74,581 options were exercised to purchase shares of Common Stock at an average exercise price of $1.34 per share.

Certain senior employees and directors are entitled to full acceleration of their unvested options upon the occurrence of both a change in control of the Company and the end of their engagement with the Company.

In 2019, the Company adopted a new incentive plan (the "2019 Plan") to grant 1,000 options, exercisable for Common Stock.

The aggregate number of shares of Common Stock that may be delivered pursuant to the 2019 Plan will automatically increase on January 1 of each year, commencing on January 1, 2020 and ending on (and including) January 1, 2029, in an amount equal to four percent (4%) of the total number of shares of Common Stock outstanding on December 31 of the preceding calendar year. Notwithstanding the foregoing, the Board of Directors may act prior to January 1 of a given year to provide that there will be no January 1 increase for such year or that the increase for such year will be a lesser number of Common Stock than provided herein. On January 1, 2020, the number of shares of Common Stock available to grant under the 2019 Plan was increased by 914,741.

On March 25, 2020, the Board of Directors approved the grant of 814,700 options without consideration to 65 employees, one consultant, four senior officers (one of whom is a consultant), and six directors under the 2019 Plan. These options were granted at an exercise price of $6.21 per share with vesting periods ranging from three to four years. Directors and senior officers are entitled to full acceleration of their unvested options upon the occurrence of both a change in control of the Company and the end of their engagement with the Company.

On May 5, 2020, the Board of Directors approved the grant of 79,000 options without consideration to four employees, under the 2019 Plan. These options were granted at an exercise price of $5.59 per share with a vesting period of four years.

As of September 30, 2020, there were 48,041 shares available for issuance under the 2019 Plan. Refer to Note 11A for options granted on October 2, 2020.

The fair value of each option was estimated as of the date of grant or reporting period using the Black-Scholes option-pricing model, using the following assumptions:

The cost of the benefit embodied in the options granted during the nine months ended September 30, 2020, based on their fair value at the grant date, is estimated to be $3.8 thousand. These amounts will be recognized in the condensed consolidated statements of operations over the vesting period.

Warrants:

As of September 30, 2020 and December 31, 2019, the Company had the following outstanding warrants to purchase Common Stock as follows:

236,552 warrants were fully vested and exercisable on the date of their issuance. The remainder of the warrants will vest and become exercisable subject to achievement of certain milestones specified in the agreement as follows:

The Company may redeem the Public Warrants:

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a "cashless basis," as described in the warrant agreement. The exercise price and number of shares of Common Stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of Common Stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants.
