Exhibit 99.1

Datavault AI Inc. (NASDAQ: DVLT) Announces a Distribution Date of December 24, 2025 for the Dream Bowl Meme Coin tokens to All Eligible Record Equityholders of Datavault AI and Holders of Common Stock of Scilex Holding Company

PHILADELPHIA, PA – Datavault AI Inc. (NASDAQ: DVLT) (“Datavault AI” or the “Company”), a leader in data monetization, credentialing, and digital engagement technologies, today announced that its board of directors (the “Datavault Board”) has set December 24, 2025 as the distribution date for the Dream Bowl 2026 Meme Coin token (the “Meme Coin”) to all eligible record equityholders of Datavault AI. December 24, 2025 will also be the distribution date for Datavault AI’s voluntary distribution of Meme Coins to record holders of common stock of Scilex Holding Company (NASDAQ: SCLX), which is being made as a token of Datavault AI’s appreciation for Scilex’s relationship with Datavault AI as a significant stockholder of Datavault AI, licensing partner and co-sponsor of the Dream Bowl XIV event to be held on January 11, 2026. The previously announced record date for the distribution of the Meme Coins was November 25, 2025.

Datavault AI expects to begin mailing detailed instructions, on or about December 12, 2025, regarding wallet setup, token access, and distribution procedures to stockholders of record of both Datavault AI and Scilex on the books and records of the transfer agents of Datavault AI and Scilex. Datavault AI also expects to file a Current Report on Form 8-K with the Securities and Exchange Commission on or about the same date outlining such instructions. Any stockholders of Datavault AI and/or Scilex that hold their shares of common stock of Datavault AI and/or Scilex in “street name” through a brokerage firm, bank, dealer or other similar organization should receive such instructions and other information from their broker, bank, dealer or other similar organization once such organizations receive the instructions from Datavault AI.

In order to receive the Meme Coins, all eligible recipients will be required to open a digital wallet with Datavault AI and execute an Opt-In Agreement, pursuant to which such holders will agree, among other things, to the payment conditions set forth therein, and acknowledge that such holders understand the process for receiving the Meme Coins, that the Datavault Board can change the record date or payment date or revoke the distribution prior to the payment date, and that the Meme Coins may not have or maintain any value.

Datavault AI remains firmly committed to stockholder value creation and continuous innovation. Datavault AI will commemorate the upcoming Dream Bowl XIV through this one-time distribution of the Meme Coins to eligible record equity holders of Datavault AI and record holders of common stock of Scilex. Each holder will receive an exclusive commemorative digital collectible designed with utility features, including immutable proof of ownership, embedded ticketing details, and exclusive content related to invited athletes, game highlights, and event access. The Meme Coins will be airdropped to DataVault® wallets beginning on December 24, 2025, subject to recipients opening a digital wallet with Datavault AI and executing an Opt-In Agreement (including to provide any additional documentation requested by Datavault AI to verify any shares of common stock of Datavault AI and/or Scilex that are held in “street name” with a brokerage firm, bank, dealer or other similar organization).

The record date for the distribution may be changed by the Datavault Board for any reason at any time prior to the actual distribution date, and payment of the distribution is conditioned upon the Datavault Board not having revoked the distribution prior to the distribution date, including for a material change to the solvency or surplus analysis presented to the Datavault Board. 

The Meme Coin is a digital collectible intended solely for personal, non-commercial use in connection with the Dream Bowl XIV event to be held on January 11, 2026. The Meme Coin does not: (i) represent or confer any equity, voting, dividend, profit-sharing, or ownership rights in Datavault AI or any other entity; (ii) provide any right to receive monetary payments, distributions, or appreciation; or (iii) create any expectation of profit or reliance on the managerial or entrepreneurial efforts of Datavault AI or others. The Meme Coin is not designed or intended to function as an investment, currency, or financial product, and it is not being offered, sold, or distributed for fundraising or capital-raising purposes. Use of the Meme Coin is limited to entertainment, event-access, and digital-collectible functions. Any transferability features are provided solely to support personal digital item portability and not to facilitate or imply investment or speculative use.

The Meme Coins will be tradeable on Datavault AI’s proprietary Information Data Exchange, which acts as a digital marketplace where registered buyers and sellers can securely exchange payment for data assets, including the Meme Coins. Datavault AI will notify holders of Meme Coins via email when they can commence trading the Meme Coins on the Information Data Exchange. Datavault AI currently anticipates that trading of the Meme Coins on such exchange will commence on or about January 11, 2026. Holders of Meme Coins may also be able to export the Meme Coins to other digital wallets. While there will be no fees associated with an eligible holder of Datavault AI securities or Scilex common stock opening a digital wallet with Datavault AI for purposes of accepting the Meme Coins in the Distribution, trades of Meme Coins made on the Information Data Exchange will incur ordinary course trading fees that are based on transaction value and embedded within the terms of the applicable smart contract. Meme Coins that are exported to and traded on other trading platforms or digital exchanges may be subject to additional fees not imposed by Datavault AI.

Exhibit 99.3

Form of Datavault AI Inc. Opt-In Agreement

The undersigned (“me” or “I”) understands that Datavault AI Inc., a Delaware corporation (“Datavault”), declared a dividend (the “Distribution”) of Dream Bowl 2026 Meme Coin tokens (such tokens, the “Meme Coins”) to the holders of the following Datavault securities, in each case as of the close of business on November 25, 2025 (such date, subject to the right of Datavault’s board of directors (the “Datavault Board”) to change to a later date, the “Record Date”): (i) Datavault’s common stock, par value $0.0001 per share (such stock, the “Datavault Common Stock” and such record holders, the “Record Datavault Common Holders”), (ii) certain warrants to purchase Datavault Common Stock that have not been exercised and settled prior to the Record Date (and which have the right to participate in the Distribution pursuant to the terms of their respective warrants) (such record holders, the “Record Datavault Warrant Holders” and such warrants, the “Record Datavault Warrants”), (iii) certain convertible promissory notes of Datavault that have not been converted and settled prior to the Record Date (and which have the right to participate in the Distribution pursuant to the terms of their respective notes) (such record holders, the “Record Datavault Note Holders” and such notes, the “Record Datavault Notes”) and (iv) certain equity awards and/or grants that are issued and outstanding as of the Record Date and which were granted under Datavault’s stock option, stock incentive or other equity incentive plans that have not been exercised or converted and settled (or, in the case of restricted stock awards, that have not yet vested) prior to the Record Date and which are entitled to participate in the Distribution pursuant to the terms of their respective awards and/or grants (such awards and/or grants, the “Record Datavault Awards” and such record holders, “Record Datavault Award Holders” and together with the Record Datavault Common Holders, the Record Datavault Warrant Holders, and the Record Datavault Note Holders, the “Record Holders”). The preceding Datavault securities held by the Record Holders as of the Record Date are collectively referred to herein as the “Datavault Securities”.

The Distribution will be (i) made on the basis of one Meme Coin for each share of Datavault Common Stock held (or underlying the applicable Datavault Securities held) by such Record Holders on the Record Date and (ii) paid beginning on December 24, 2025 (or such other date as determined by the Datavault Board, the “Payment Date”), subject to the satisfaction of the Payment Conditions (as defined below) by the applicable Record Holder.

The fair market value per Meme Coin is $0.0000014, as of November 19, 2025 (the “Valuation Date”), based on an independent valuation conducted by a third-party valuation firm at the request of Datavault, and such value assumes that the Meme Coins are illiquid through January 9, 2026.

By signing below, I hereby acknowledge and agree that:

This Agreement documents my irrevocable election (“Election”) to satisfy the Payment Conditions, comply with the terms and conditions as set forth in this Agreement, including with respect to my tax reporting obligations, and receive payment of the Distribution. I acknowledge and agree that by submitting my signature on this Agreement in a “.pdf” format data file or other digital format, such signature shall create a valid and binding obligation on me (or, if signing for an entity, the entity on whose behalf such signature is executed) with the same force and effect as if such “.pdf” or other digital signature page were an original thereof.

I hereby represent that:

¹ Stockholder of Record: Shares Registered in Your Name. If at the close of business on the Record Date, your shares of Datavault Common Stock were registered directly in your name with VStock LLC, Datavault’s transfer agent (the “Transfer Agent”), then you are the stockholder of record for such shares and a Record Datavault Common Holder and you will be eligible to receive the Distribution, subject to the terms of this Agreement, including the satisfaction of the Payment Conditions. If there is any conflict between the amount of shares of Datavault Common Stock stated herein and the records of the Transfer Agent, then the Transfer Agent’s records shall prevail in accordance with the terms and conditions of this Agreement.

Beneficial Owner: Shares Registered in the Name of a Nominee. If at the close of business on the Record Date, your shares of Datavault Common Stock were held, not in your name, but rather at a brokerage firm, bank, dealer or other similar organization (i.e., with a Nominee), then you are a beneficial owner of shares held in “street name”, and such Nominee is considered the stockholder of record, or the Record Datavault Common Holder, and such Nominee should have distributed to you a letter from Datavault informing you that you will be eligible to receive the Distribution, subject to the terms of this Agreement, including the satisfaction of the Payment Conditions and delivery of any additional information necessary to confirm your holdings of Datavault Common Stock as described elsewhere in this Agreement. As noted elsewhere in this Agreement, if Datavault is unable to verify the number of shares of Datavault Common Stock that you hold with such Nominee as set forth in the column to the right, no Meme Coins will be distributed to you until such time as your share information can be verified by the Information Agent.

² If you are a Record Datavault Warrant Holder, Record Datavault Note Holder and/or Record Datavault Award Holder, all shares of Datavault Common Stock subject to the applicable Datavault Securities held in your record name (on the books and records of Datavault) on the Record Date will be eligible to receive the Distribution, subject to the terms of this Agreement, including the satisfaction of the Payment Conditions. If there is any conflict between the amount of shares of Datavault Common Stock subject to your Datavault Securities as stated herein and the records of Datavault, then Datavault’s records shall prevail.

RISK FACTORS

Prior to making any decision regarding your execution of this Agreement and acceptance of Dream Bowl 2026 Meme Coin tokens (such tokens, the “Meme Coins”), you should carefully consider the following Risk Factors. If any of the events discussed in the Risk Factors occur, the value of the Meme Coins you receive could be adversely affected.

The value of the Meme Coins may increase or decrease between the Record Date and the Payment Date and/or at any time following the Payment Date. The value of such coins may also be highly volatile.

The Distribution will be in the form of a digital asset, the Meme Coin. If the value of the Meme Coins decreases between the Record Date and the Payment Date, participating holders may receive less value than initially expected by those who elected to receive the Distribution. Additionally, the value of the Meme Coin may decrease after the Payment Date. Once you have made the Election, it is irrevocable. Datavault will not be responsible for any decrease in the value of the Meme Coins.

In addition, digital assets, such as the Meme Coin, generally are highly volatile assets and do not pay interest or other returns, and so the ability to generate a return on the Meme Coins will depend on whether there is appreciation in the value of digital assets.  

The irreversibility of digital asset transactions exposes you to risks of theft, loss and human error, which could negatively impact your rights to the Distribution. 

Once a transaction has been verified and recorded in a block that is added to the blockchain, an incorrect transfer of digital assets or a theft of digital assets generally will not be reversible, and you may not be capable of seeking compensation for any such transfer or theft. If you provide Datavault with the wrong wallet address (which is a valid address), the owner of such wallet address will receive the benefit of your Meme Coin Distribution, and you will receive nothing. Datavault will be unable to revert or otherwise recover the impacted digital assets and will not be responsible for any loss. If you provide Datavault with an invalid wallet address and the transfer is rejected by the Datavault network, Datavault may, at its option, refuse or reasonably delay payment of the Distribution. You are encouraged to confirm your wallet address prior to submitting your Election.

Meme Coins and other digital assets are novel assets and are subject to significant legal, commercial, regulatory and technical uncertainty.

The Meme Coins and other digital assets are relatively novel and are subject to significant legal, commercial, regulatory and technical uncertainty, which could adversely impact their price. The application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of the Meme Coin. Regulators in the United States or foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of the Meme Coins or the ability of individuals or institutions to own or transfer Meme Coins.

The growth of the digital assets industry in general, and the use and acceptance of the Meme Coin in particular, may also impact the price of the Meme Coins and is subject to a high degree of uncertainty. The pace of worldwide growth in the adoption and use of the Meme Coin may depend, for instance, on public familiarity with digital assets, ease of buying, accessing or gaining exposure to the Meme Coin, institutional demand for the Meme Coin as an investment asset, the participation of traditional financial institutions in the digital assets industry, consumer demand for the Meme Coin as a means of payment, and the availability and popularity of alternatives to the Meme Coin. Even if growth in Meme Coin adoption occurs in the near or medium term, there is no assurance that Meme Coin usage will continue to grow over the long term.

Because the Meme Coin has no physical existence beyond the record of transactions on the Meme Coin blockchain, a variety of technical factors related to the Meme Coin blockchain could also impact the price of Meme Coins. The liquidity of the Meme Coins may also be reduced, and damage to the public perception of the Meme Coin may occur, if financial institutions were to deny or limit banking services to businesses that hold the Meme Coins, provide Meme Coin-related services or accept the Meme Coin as payment, which could also decrease the price of the Meme Coins.

The liquidity of the Meme Coin may also be impacted to the extent that changes in applicable laws and regulatory requirements negatively impact the ability of exchanges and trading venues to provide services for the Meme Coin.

The lack of legal recourse and insurance for digital assets increases the risk of total loss in the event of theft or destruction.

Digital assets, including the Meme Coins, will generally not be insured against theft, loss or destruction. If an event occurs where you lose your Meme Coins, whether due to cyberattacks, fraud or other malicious activities, you may not have any viable legal recourse or ability to recover the lost assets. Unlike funds held in insured banking institutions, digital assets are not protected by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. If your digital assets, including Meme Coins, are lost under circumstances that render another party liable, there is no guarantee that the responsible party will have the financial resources to compensate you. As a result, you could face financial losses.

Cryptocurrency holdings are less liquid than cash and cash equivalents and may not be able to serve as a source of liquidity for you to the same extent as cash and cash equivalents.

Historically, the crypto markets have been characterized by significant volatility in price, limited liquidity and trading volumes compared to sovereign currencies markets, relative anonymity, a developing regulatory landscape, potential susceptibility to market abuse and manipulation, compliance and internal control failures at exchanges, and various other risks inherent in its entirely electronic, virtual form and decentralized network. During times of market instability, you may not be able to sell your cryptocurrency at favorable prices or at all.

Further, cryptocurrency, such as the Meme Coin, does not enjoy the same protections as are available to cash or securities deposited with or transacted by institutions subject to regulation by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. You could be unable to sell Meme Coins or have to sell Meme Coins at a significant loss.

Meme Coins do not pay interest or dividends. 

Meme Coins do not pay interest or other returns, and you may only be able to generate cash from Meme Coins if you sell your Meme Coins or implement strategies to create income streams or otherwise generate cash by using your Meme Coin holdings. Even if you pursue any such strategies, you may be unable to create income streams or otherwise generate cash from Meme Coins, and any such strategies may subject you to additional risks.

If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to your Meme Coins, or if your private keys are lost or destroyed or other similar circumstances or events occur, you may lose some or all of your Meme Coins.

Security breaches and cyberattacks are of particular concern with respect to cryptocurrency, including Meme Coins. Blockchain-based cryptocurrencies and the entities that provide services to participants in the cryptocurrency ecosystem have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities. A successful security breach or cyberattack could result in a partial or total loss of your cryptocurrency in a manner that may not be covered by insurance or the liability provisions of the custody agreements with the custodians who hold your cryptocurrency. 

I understand that there may be legal and tax consequences from the Election, execution of the Opt-In Agreement and receipt of the Distribution. Datavault encourages all Record Holders to seek legal and tax advice from qualified legal counsel and a tax professional before deciding to make the Election, execute this Agreement and receive the Distribution.

We encourage any Record Holder that has questions concerning the Election process to contact Alliance Advisors, our Information Agent, at 1-855-206-1373 (or 1-732-848-0858 for international holders) or [email protected]. This Agreement may be executed and submitted to the Information Agent only via www.dreambowlcoin.com. Any Agreement that is mailed, faxed, or emailed to any representative of Datavault or to the Information Agent will not be accepted.

I hereby make my irrevocable Election to accept the Distribution, subject to the foregoing terms and conditions.

This Agreement documents my irrevocable election (“Election”) to satisfy the Payment Conditions, comply with the terms and conditions as set forth in this Agreement, including with respect to my tax reporting obligations, and receive payment of the Distribution. I acknowledge and agree that by submitting my signature on this Agreement in a “.pdf” format data file or other digital format, such signature shall create a valid and binding obligation on me (or, if signing for an entity, the entity on whose behalf such signature is executed) with the same force and effect as if such “.pdf” or other digital signature page were an original thereof.

I hereby represent that:

¹ Stockholder of Record: Shares Registered in Your Name. If at the close of business on the Record Date, your shares of Scilex Common Stock were registered directly in your name with Continental Stock Transfer and Trust Company, Scilex’s transfer agent (the “Transfer Agent”), then you are the stockholder of record for such shares and a Record Holder and you will be eligible to receive the Distribution, subject to the terms of this Agreement, including the satisfaction of the Payment Conditions. If there is any conflict between the amount of shares of Scilex Common Stock stated herein and the records of the Transfer Agent, then the Transfer Agent’s records shall prevail in accordance with the terms and conditions of this Agreement.

Beneficial Owner: Shares Registered in the Name of a Nominee. If at the close of business on the Record Date, your shares of Scilex Common Stock were held, not in your name, but rather at a brokerage firm, bank, dealer or other similar organization (i.e., with a Nominee), then you are a beneficial owner of shares held in “street name”, and such Nominee is considered the stockholder of record, or the Record Holder, such Nominee should have distributed to you a letter from Datavault informing you that you will be eligible to receive the Distribution, subject to the terms of this Agreement, including the satisfaction of the Payment Conditions and delivery of any additional information necessary to confirm your holdings of Scilex Common Stock as described elsewhere in this Agreement. As noted elsewhere in this Agreement, if Datavault is unable to verify the number of shares of Scilex Common Stock that you hold with such Nominee as set forth in the column to the right, no Meme Coins will be distributed to you until such time as your share information can be verified by the Information Agent.

(Meme Coin transactions are irreversible; it is advised that you cut and paste your digital wallet address into this field)

RISK FACTORS

Prior to making any decision regarding your execution of this Agreement and acceptance of Dream Bowl 2026 Meme Coin tokens (such tokens, the “Meme Coins”), you should carefully consider the following Risk Factors. If any of the events discussed in the Risk Factors occur, the value of the Meme Coins you receive could be adversely affected.

The value of the Meme Coins may increase or decrease between the Record Date and the Payment Date and/or at any time following the Payment Date. The value of such coins may also be highly volatile.

The Distribution will be in the form of a digital asset, the Meme Coin. If the value of the Meme Coins decreases between the Record Date and the Payment Date, participating holders may receive less value than initially expected by those who elected to receive the Distribution. Additionally, the value of the Meme Coin may decrease after the Payment Date. Once you have made the Election, it is irrevocable. Datavault will not be responsible for any decrease in the value of the Meme Coins.

In addition, digital assets, such as the Meme Coin, generally are highly volatile assets and do not pay interest or other returns, and so the ability to generate a return on the Meme Coins will depend on whether there is appreciation in the value of digital assets.  

The irreversibility of digital asset transactions exposes you to risks of theft, loss and human error, which could negatively impact your rights to the Distribution. 

Once a transaction has been verified and recorded in a block that is added to the blockchain, an incorrect transfer of digital assets or a theft of digital assets generally will not be reversible, and you may not be capable of seeking compensation for any such transfer or theft. If you provide Datavault with the wrong wallet address (which is a valid address), the owner of such wallet address will receive the benefit of your Meme Coin Distribution, and you will receive nothing. Datavault will be unable to revert or otherwise recover the impacted digital assets and will not be responsible for any loss. If you provide Datavault with an invalid wallet address and the transfer is rejected by the Datavault network, Datavault may, at its option, refuse or reasonably delay payment of the Distribution. You are encouraged to confirm your wallet address prior to submitting your Election.

Meme Coins and other digital assets are novel assets and are subject to significant legal, commercial, regulatory and technical uncertainty.

The Meme Coins and other digital assets are relatively novel and are subject to significant legal, commercial, regulatory and technical uncertainty, which could adversely impact their price. The application of state and federal securities laws and other laws and regulations to digital assets is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may interpret or apply existing laws and regulations in a manner that adversely affects the price of the Meme Coin. Regulators in the United States or foreign countries may also enact new laws and regulations, or pursue regulatory, legislative, enforcement or judicial actions, that could materially impact the price of the Meme Coins or the ability of individuals or institutions to own or transfer Meme Coins.

The growth of the digital assets industry in general, and the use and acceptance of the Meme Coin in particular, may also impact the price of the Meme Coins and is subject to a high degree of uncertainty. The pace of worldwide growth in the adoption and use of the Meme Coin may depend, for instance, on public familiarity with digital assets, ease of buying, accessing or gaining exposure to the Meme Coin, institutional demand for the Meme Coin as an investment asset, the participation of traditional financial institutions in the digital assets industry, consumer demand for the Meme Coin as a means of payment, and the availability and popularity of alternatives to the Meme Coin. Even if growth in Meme Coin adoption occurs in the near or medium term, there is no assurance that Meme Coin usage will continue to grow over the long term.

Because the Meme Coin has no physical existence beyond the record of transactions on the Meme Coin blockchain, a variety of technical factors related to the Meme Coin blockchain could also impact the price of Meme Coins. The liquidity of the Meme Coins may also be reduced, and damage to the public perception of the Meme Coin may occur, if financial institutions were to deny or limit banking services to businesses that hold the Meme Coins, provide Meme Coin-related services or accept the Meme Coin as payment, which could also decrease the price of the Meme Coins.

The liquidity of the Meme Coin may also be impacted to the extent that changes in applicable laws and regulatory requirements negatively impact the ability of exchanges and trading venues to provide services for the Meme Coin.

The lack of legal recourse and insurance for digital assets increases the risk of total loss in the event of theft or destruction.

Digital assets, including the Meme Coins, will generally not be insured against theft, loss or destruction. If an event occurs where you lose your Meme Coins, whether due to cyberattacks, fraud or other malicious activities, you may not have any viable legal recourse or ability to recover the lost assets. Unlike funds held in insured banking institutions, digital assets are not protected by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. If your digital assets, including Meme Coins, are lost under circumstances that render another party liable, there is no guarantee that the responsible party will have the financial resources to compensate you. As a result, you could face financial losses.

Cryptocurrency holdings are less liquid than cash and cash equivalents and may not be able to serve as a source of liquidity for you to the same extent as cash and cash equivalents.

Historically, the crypto markets have been characterized by significant volatility in price, limited liquidity and trading volumes compared to sovereign currencies markets, relative anonymity, a developing regulatory landscape, potential susceptibility to market abuse and manipulation, compliance and internal control failures at exchanges, and various other risks inherent in its entirely electronic, virtual form and decentralized network. During times of market instability, you may not be able to sell your cryptocurrency at favorable prices or at all.

Further, cryptocurrency, such as the Meme Coin, does not enjoy the same protections as are available to cash or securities deposited with or transacted by institutions subject to regulation by the Federal Deposit Insurance Corporation or the Securities Investor Protection Corporation. You could be unable to sell Meme Coins or have to sell Meme Coins at a significant loss.

Meme Coins do not pay interest or dividends. 

Meme Coins do not pay interest or other returns, and you may only be able to generate cash from Meme Coins if you sell your Meme Coins or implement strategies to create income streams or otherwise generate cash by using your Meme Coin holdings. Even if you pursue any such strategies, you may be unable to create income streams or otherwise generate cash from Meme Coins, and any such strategies may subject you to additional risks.

If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to your Meme Coins, or if your private keys are lost or destroyed or other similar circumstances or events occur, you may lose some or all of your Meme Coins.

Security breaches and cyberattacks are of particular concern with respect to cryptocurrency, including Meme Coins. Blockchain-based cryptocurrencies and the entities that provide services to participants in the cryptocurrency ecosystem have been, and may in the future be, subject to security breaches, cyberattacks, or other malicious activities. A successful security breach or cyberattack could result in a partial or total loss of your cryptocurrency in a manner that may not be covered by insurance or the liability provisions of the custody agreements with the custodians who hold your cryptocurrency. 

I understand that there may be legal and tax consequences from the Election, execution of the Opt-In Agreement and receipt of the Distribution. Datavault encourages all Record Holders to seek legal and tax advice from qualified legal counsel and a tax professional before deciding to make the Election, execute this Agreement and receive the Distribution.

We encourage any Record Holder that has questions concerning the Election process to contact Alliance Advisors, our Information Agent, at 1-855-206-1373 (or 1-732-848-0858 for international holders) or [email protected]. This Agreement may be executed and submitted to the Information Agent only via www.dreambowlcoin.com. Any Agreement that is mailed, faxed, or emailed to any representative of Datavault or to the Information Agent will not be accepted.

I hereby make my irrevocable Election to accept the Distribution, subject to the foregoing terms and conditions.
