Each whole warrant initially entitles the holder to purchase one Class A share at an exercise price of $11.50 per share, subject to adjustment as provided in the Warrant Agreement. The warrants may be exercised only during the exercise period described in the Warrant Agreement and only if the applicable conditions to exercise are satisfied.

If your warrants are held through a broker, bank, or other nominee, please contact that institution for instructions on how to submit an exercise instruction through its procedures. Public warrants were initially represented in book-entry form through The Depository Trust Company (DTC), and beneficial ownership and transfers of book-entry public warrants are reflected through DTC, its nominee, and DTC participants.

If you are a registered holder, the Warrant Agreement provides that exercise requires delivery to the warrant agent of the warrant or book-entry warrant, a properly completed and executed election to purchase, and payment in full of the Warrant Price and any applicable taxes. Payment may be made in lawful money of the United States, by good bank draft, certified check payable to the order of the warrant agent, or by wire transfer of immediately available funds, except where cashless exercise is permitted or required under the Warrant Agreement.

Boost Run cannot provide individualized brokerage, investment, legal, or tax advice. Please consult your broker, legal advisor, or tax advisor regarding your specific circumstances.

The Warrant Agreement provides that the warrants may be exercised beginning 30 days after completion of the Company's initial business combination and ending at the earliest of (i) 5:00 p.m. New York City time on the date that is five years after completion of the initial business combination, (ii) the liquidation of the Company, or (iii) if the warrants are redeemed, 5:00 p.m. New York City time on the redemption date.

Because the business combination closed on May 8, 2026, the first day on which warrants may be exercised under the 30-day timing provision is June 7, 2026, subject to the terms and conditions of the Warrant Agreement. The Company is not obligated to deliver shares upon exercise unless a registration statement covering the shares issuable upon exercise is effective and a related prospectus is current, unless a valid exemption from registration is available.

The Warrant Agreement provides that the warrants expire at the earliest of (i) 5:00 p.m. New York City time on the date that is five years after completion of the initial business combination, (ii) the liquidation of the Company, or (iii) if the warrants are redeemed, 5:00 p.m. New York City time on the redemption date. Any outstanding warrant not exercised on or before the expiration date becomes void.

Because the business combination closed on May 8, 2026, the five-year outside expiration date is May 8, 2031, subject to earlier expiration upon redemption or liquidation. The Company may extend the warrant duration by delaying the expiration date with at least 20 days' prior written notice to registered holders; any extension must be identical in duration among all warrants.

Transferability depends on the type of warrant and how it is held. Public warrants were initially represented in book-entry form through DTC, and beneficial ownership and transfers of book-entry public warrants are reflected through DTC, its nominee, and DTC participants. If you hold warrants through a broker, bank, or other nominee, please contact that institution regarding transfer procedures.

Private placement warrants and working capital warrants are subject to separate transfer restrictions. The Warrant Agreement provides that those warrants may not be transferred, assigned, or sold until 30 days after completion of the initial business combination, except to specified permitted transferees and subject to the transferee agreeing to be bound by applicable transfer restrictions.

Boost Run cannot confirm whether any particular holder's warrants are transferable in a specific transaction. Holders should consult their broker, legal advisor, or other professional advisor regarding their own holdings and any applicable restrictions.

The Warrant Agreement permits or requires cashless exercise only in specified circumstances. In a cashless exercise, the holder does not pay the exercise price in cash; instead, the holder surrenders warrants and receives a number of shares determined by the formula specified in the Warrant Agreement.

For a cashless exercise in connection with a redemption where the Company's board has elected to require all holders to exercise on a cashless basis, the number of shares issuable is determined by dividing the product of the number of shares underlying the warrants multiplied by the excess of fair market value over the Warrant Price, by the fair market value. For this purpose, fair market value means the average reported closing price of the Class A shares for the 10 trading days ending on the third trading day before the notice of redemption is sent to warrant holders.

The Warrant Agreement also provides for cashless exercise if a required registration statement covering the shares issuable upon exercise has not become effective by the 60th business day after closing of the initial business combination, or during any period when the Company has failed to maintain an effective registration statement covering the shares issuable upon exercise.

The Warrant Agreement permits the Company to redeem all, but not less than all, of the outstanding warrants during the exercise period at a redemption price of $0.01 per warrant if specified conditions are satisfied. Those conditions include that the reference value equals or exceeds $18.00 per share, subject to adjustment under the Warrant Agreement, and that an effective registration statement covering the shares issuable upon exercise and a current prospectus relating to those shares are available throughout the measurement period and the 30-day redemption period.

The Warrant Agreement defines reference value as the last reported sales price of the Class A shares for any 20 trading days within the 30-trading-day period commencing at least 30 days after completion of the initial business combination and ending on the third trading day before notice of redemption is given. If the Company elects to redeem, it must fix a redemption date and mail notice of redemption to registered holders not less than 30 days before that redemption date.

Boost Run does not comment on whether or when it may redeem the warrants. Any redemption or other material action relating to the warrants would be made in accordance with the Warrant Agreement and communicated through appropriate public disclosure if and when required.

Boost Run cannot provide tax advice regarding the ownership, transfer, exercise, cashless exercise, sale, redemption, or expiration of warrants. The tax consequences of holding or exercising warrants may vary depending on the holder's particular facts and circumstances, including the holder's tax residence, holding period, status, and manner of disposition.

The Warrant Agreement provides that a holder exercising warrants must pay the Warrant Price and any applicable taxes due in connection with the exercise, exchange, and issuance of shares. The Company will pay taxes and charges imposed on the Company or the warrant agent in respect of the issuance or delivery of shares upon exercise, but the Company is not obligated to pay transfer taxes in respect of the warrants or the shares.

Please consult your own tax advisor regarding the tax consequences of holding, transferring, exercising, selling, redeeming, or allowing the warrants to expire.

Continental Stock Transfer & Trust Company is the warrant agent under the Warrant Agreement, dated November 7, 2024, by and between Willow Lane Acquisition Corp. and Continental Stock Transfer & Trust Company, as warrant agent, as assumed by Boost Run, Inc. in connection with the closing of the business combination.
