Exhibit 4.5



DESCRIPTION OF REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934



As of December 31, 2021, the end of the
period covered by this Annual Report on Form 10-K, Digital Health Acquisition Corp. (the “Company,” “we,”
 “us,” or “our”) had three classes of securities registered under Section 12 of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”): the Company’s units, common stock, and warrants.



The following description of the Company’s
capital stock and provisions of the Company’s amended and restated certificate of incorporation, bylaws and the Delaware General
Corporation Law are summaries and are qualified in their entirety by reference to the Company’s amended and restated certificate
of incorporation and bylaws and the text of the Delaware General Corporation Law. Copies of these documents have been filed with the SEC
as exhibits to the Annual Report on Form 10-K to which this description has been filed as an exhibit.



General



Our amended and restated certificate of incorporation
authorizes the issuance of 51,000,000 shares consisting of (a) 50,000,000 shares of common stock (the “Common Stock”),
and (b) 1,000,000 shares of preferred stock (the “Preferred Stock”). As of the date of this Annual Report on Form 10-K,
14,932,000 shares of common stock are issued and outstanding and no preferred shares are issued and outstanding. The following description
summarizes all of the material terms of our securities. Because it is only a summary, it may not contain all the information that is important
to you. For a complete description you should refer to our amended and restated certificate of incorporation and bylaws, which are filed
as exhibits to this Annual Report on Form 10-K.



Units



Each unit consists of one share of common stock
and one warrant. Each warrant entitles the holder thereof to purchase one (1) share of common stock at a price of $11.50 per whole
share, subject to adjustment. Each warrant will become exercisable on the later of one year after the closing of the IPO, or November 8,
2022, or 30 days after the completion of an initial business combination, and will expire five years after the completion of an initial
business combination, or earlier upon redemption. Pursuant to the warrant agreement, a warrantholder may exercise its warrants only for
a whole number of shares.



The shares of common stock and warrants comprising
the units became separately traded on or about December 30, 2021.



Common Stock



Our holders of record of our common stock are
entitled to one vote for each share held on all matters to be voted on by stockholders. In connection with any vote held to approve our
initial business combination, our insiders, officers and directors, have agreed to vote their respective shares of common stock owned
by them immediately prior to the IPO, including both the insider shares and any shares acquired in the IPO or following the IPO in the
open market, in favor of the proposed business combination.



We will consummate our initial business combination
only if we have net tangible assets of at least $5,000,001 and a majority of the outstanding shares of common stock voted are voted in
favor of the business combination.



Pursuant to our amended and restated certificate
of incorporation, if we do not consummate our initial business combination within 12 months from the closing of the IPO, we will (i) cease
all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days
thereafter, redeem 100% of the outstanding public shares, which redemption will completely extinguish public stockholders’ rights
as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as
promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors,
dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims
of creditors and the requirements of other applicable law. Our insiders have agreed to waive their rights to share in any distribution
with respect to their insider shares.













Our stockholders have no conversion, preemptive
or other subscription rights and there are no sinking fund or redemption provisions applicable to the shares of common stock, except that
public stockholders have the right to sell their shares to us in any tender offer or have their shares of common stock converted to cash
equal to their pro rata share of the trust account if they vote on the proposed business combination and the business combination is completed.



If we hold a stockholder vote to amend any provisions
of our certificate of incorporation relating to stockholder’s rights or pre-business combination activity (including the substance
or timing within which we have to complete a business combination), we will provide our public stockholders with the opportunity to redeem
their shares of common stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount
then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to
us to pay our franchise and income taxes, divided by the number of then outstanding public shares, in connection with any such vote. In
either of such events, converting stockholders would be paid their pro rata portion of the trust account promptly following consummation
of the business combination or the approval of the amendment to the certificate of incorporation. If the business combination is not consummated
or the amendment is not approved, stockholders will not be paid such amounts.



Warrants



There are 12,057,000 warrants issued and outstanding
as of December 31, 2021. Each warrant entitles the registered holder to purchase one (1) share of common stock at a price of
$11.50 per whole share, subject to adjustment as discussed below, at any time commencing on the later of 30 days after the completion
of an initial business combination or 12 months from the closing of the IPO.



However, no warrants will be exercisable for cash
unless we have an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants
and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering
the shares of common stock issuable upon exercise of the public warrants is not effective within a specified period following the consummation
of the initial business combination, warrant holders may, until such time as there is an effective registration statement and during any
period when we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the
exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or
another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In the event of such cashless
exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the
quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the
difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market
value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock
for the 5 trading days ending on the trading day prior to the date of exercise. The warrants will expire on the fifth anniversary of the
completion of an initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.



The Private Placement Warrants are identical to
the warrants underlying the units in the IPO. The Company may call the warrants for redemption, in whole and not in part, at a price
of $0.01 per warrant,



| | ● | at any time after the warrants become exercisable,
| | - | --------------------------------------------------



| | ● | upon not less than 30 days’ prior written notice of redemption to each warrant holder,
| | - | --------------------------------------------------------------------------------------



| | ● | if, and only if, the reported last sale price of the shares of common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing at any time after the warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders; and
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------













| | ● | if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------



The right to exercise will be forfeited unless
the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder
of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such
warrant.



The redemption criteria for our warrants have
been established at a price which is intended to provide warrant holders a reasonable premium to the initial exercise price and provide
a sufficient differential between the then-prevailing share price and the warrant exercise price so that if the share price declines as
a result of our redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants.



If we call the warrants for redemption as described
above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.”
In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to
the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by
the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair
market value. The “fair market value” for this purpose shall mean the average reported last sale price of the shares of common
stock for the 5 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders
of warrants.



The warrants were issued in registered form under
a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides
that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision
or to make any other change that does not adversely affect the interests of the registered holders. For any other change, the warrant
agreement requires the approval by the holders of at least a majority of the then outstanding public warrants if such amendment is undertaken
prior to or in connection with the consummation of a business combination or at least a majority of the then outstanding warrants if the
amendment is undertaken after the consummation of a business combination.



The exercise price and number of shares of common
stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary
dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted
for issuances of shares of common stock at a price below their respective exercise prices.



If (x) we issue additional shares of common
stock or equity-linked securities for capital raising purposes in connection with the closing of the initial business combination at an
issue price or effective issue price of less than $9.20 per share of common stock (with such issue price or effective issue price to be
determined in good faith by our board of directors, and in the case of any such issuance to our Sponsor, initial stockholders or their
affiliates, without taking into account any founders’ shares held by them prior to such issuance), (y) the aggregate gross
proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of
the initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the
Market Value is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of
the greater of (i) the Market Value or (ii) the price at which we issue the additional shares of common stock or equity-linked
securities and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180%
of the Market Value. The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the
offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated,
accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being
exercised. The warrant holders do not have the rights or privileges of holders of shares of common stock and any voting rights until they
exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants,
each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.



Warrant holders may elect to be subject to a restriction
on the exercise of their warrants such that an electing warrant holder would not be able to exercise their warrants to the extent that,
after giving effect to such exercise, such holder would beneficially own in excess of 9.8% of the shares of common stock outstanding.













No fractional shares will be issued upon exercise
of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon
exercise, round up to the nearest whole number the number of shares of common stock to be issued to the warrant holder.



We have agreed that, subject to applicable law,
any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement will be brought and enforced
in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit
to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. This provision applies
to claims under the Securities Act but does not apply to claims under the Exchange Act or any claim for which the federal district courts
of the United States of America are the sole and exclusive forum. We note that there is uncertainty as to whether a court would enforce
this provision and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.
Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any
duty or liability created by the Securities Act or the rules and regulations thereunder.



Dividends



We have not paid any cash dividends on our common
stock to date and do not intend to pay cash dividends prior to the completion of an initial business combination. The payment of cash
dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition
subsequent to completion of a business combination. The payment of any dividends subsequent to a business combination will be within the
discretion of our board of directors at such time. It is the present intention of our board of directors to retain all earnings, if any,
for use in our business operations and, accordingly, our board of directors does not anticipate declaring any dividends in the foreseeable
future. In addition, our board of directors is not currently contemplating and does not anticipate declaring any share dividends in the
foreseeable future. Further, if we incur any indebtedness, our ability to declare dividends may be limited by restrictive covenants we
may agree to in connection therewith.



Our Transfer Agent and Warrant Agent



The transfer agent for our shares of common stock
and warrant agent for our warrants is Continental Stock Transfer & Trust Company, 1 State Street 30th Floor, New York, NY 10004.



Certain Anti-Takeover Provisions of Delaware Law and our Amended
and Restated Certificate of Incorporation and Bylaws



We are subject to the provisions of Section 203
of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging
in a “business combination” with:



| | ● | a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an “interested stockholder”);
| | - | --------------------------------------------------------------------------------------------------------------------



| | ● | an affiliate of an interested stockholder; or
| | - | ---------------------------------------------



| | ● | an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.
| | - | ------------------------------------------------------------------------------------------------------------------------------------



A
 “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203
do not apply if:



| | ● | our board of directors approves the transaction that made the stockholder an“interested stockholder,” prior to the date of the transaction;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------



| | ● | after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------













| | ● | on or subsequent to the date of the transaction, the initial business combination is approved by our board of directors and authorized at a meeting of our stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Our authorized but unissued common stock and preferred
stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including
future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved
common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest,
tender offer, merger or otherwise.



Special meeting of stockholders



Our bylaws provide that special meetings of our
stockholders may be called by resolution of the Board of Directors, or by the Chief Executive Officer, or by the holders of not less than
one-quarter of all of the shares entitled to vote at the meeting.



Advance notice requirements for stockholder
proposals and director nominations



Our bylaws provide that stockholders seeking to
bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of
stockholders must provide timely notice of their intent in writing. To be timely, a stockholder’s notice will need to be delivered
to our principal executive offices not later than the close of business on the 90th day nor earlier than the opening of business on the
120th day prior to the scheduled date of the annual meeting of stockholders. Our bylaws also specify certain requirements as to the form
and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting
of stockholders or from making nominations for directors at our annual meeting of stockholders.



Authorized but unissued shares



Our authorized but unissued common stock and preferred
stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including
future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved
common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest,
tender offer, merger or otherwise.



Exclusive forum for certain lawsuits



Our amended and restated certificate of incorporation provides that,
unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest
extent permitted by law, be the sole and exclusive forum for any (1) derivative action or proceeding brought on behalf of our company,
(2) action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of our company to our
company or our stockholders, or any claim for aiding and abetting any such alleged breach, (3) action asserting a claim against our
company or any director or officer of our company arising pursuant to any provision of the DGCL or our amended and restated certificate
of incorporation or our bylaws, or (4) action asserting a claim against us or any director or officer of our company governed by
the internal affairs doctrine except for, as to each of (1) through (4) above, any claim (A) as to which the Court of Chancery
determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party
does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is
vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or (C) arising under the federal securities
laws, including the Securities Act as to which the Court of Chancery and the federal district court for the District of Delaware shall
concurrently be the sole and exclusive forums. Notwithstanding the foregoing, the inclusion of such provision in our amended and restated
certificate of incorporation will not be deemed to be a waiver by our stockholders of our obligation to comply with federal securities
laws, rules and regulations, and the provisions of this paragraph will not apply to suits brought to enforce any liability or duty
created by the Exchange Act or any other claim for which the federal district courts of the United States of America shall be the sole
and exclusive forum. Although we believe this provision benefits us by providing increased consistency in the application of Delaware
law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and
officers. Furthermore, the enforceability of choice of forum provisions in other companies’ certificates of incorporation has been
challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.
