with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting
discount held in trust and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement
in connection with its initial Business Combination. The terms of the Merger Agreement satisfy this requirement. However, the Company
will only complete an initial Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting

of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve
the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of
a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will
be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be
$10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company
to pay its tax obligations). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be
reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). In such case, the
Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation
of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is
not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will,
pursuant to the amended and restated Certificate of Incorporation which was adopted by the Company in connection with the Initial Public
Offering (the &ldquo;Amended and Restated Certificate&rdquo;), conduct the redemptions pursuant to the tender offer rules of the U.S.
Securities and Exchange Commission (the &ldquo;SEC&rdquo;), and file tender offer documents with the SEC prior to completing a Business
Combination. If, however, a stockholder approval of the transactions is required by law, or the Company decides to obtain stockholder
approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to
the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares
irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with
a Business Combination, the holders of the Founder Shares prior to the Initial Public Offering (the &ldquo;Initial Stockholders&rdquo;)
have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering
in favor of a Business Combination. In addition, the Initial Stockholders have agreed to waive their redemption rights with respect to
their Founder Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company has agreed
not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.</FONT></P>

Company is an &ldquo;emerging growth company,&rdquo; as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our
Business Startups Act of 2012 (the &ldquo;JOBS Act&rdquo;), and it may take advantage of certain exemptions from various reporting requirements
that are applicable to other public&nbsp;companies that are not emerging growth companies including, but not limited to, not being required
to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced
disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements
of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting
standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do
not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting
standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with
the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application
dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time
private companies adopt the new or revised standard. This may make comparison of the Company&rsquo;s financial statement with another
public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition
period difficult or impossible because of the potential differences in accounting standards used.</FONT></P>

accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement
conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings
per share calculation in certain areas. The ASU is effective for fiscal years beginning after December&nbsp;15, 2023, including interim
periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&nbsp;15, 2021
and adoption must be as of the beginning of the Company&rsquo;s annual fiscal year. The Company is currently evaluating the impact of
this standard on its financial statements and related disclosures.</FONT></P>

Delaware corporation and a wholly-owned subsidiary of BCTG (&ldquo;Merger Sub&rdquo;), and Tango Therapeutics, Inc. (&ldquo;Tango&rdquo;).
Pursuant to the Merger Agreement, at the closing of the transactions contemplated thereby, Merger Sub will merge with and into Tango
(the &ldquo;Merger&rdquo;) with Tango surviving the merger as a wholly-owned subsidiary of BCTG (the &ldquo;Proposed Business Combination&rdquo;).
In addition, in connection with the consummation of the Proposed Business Combination, BCTG will be renamed &ldquo;Tango Therapeutics,
Inc.&rdquo;</FONT></P>

the Merger Agreement, BCTG has agreed to acquire all of the outstanding shares of Tango common stock (including any options or warrants
exercisable therefor) for $550,000,000 in aggregate consideration, comprising 55,000,000 shares of BCTG common stock, based on a price
of $10.00 per share (such shares being referred to herein as the &ldquo;Merger Consideration&rdquo;).</FONT></P>

Business Combination and without any further action on the part of BCTG, Merger Sub or Tango (after Tango causes each share of Tango
preferred stock that is issued and outstanding immediately prior to the consummation of the Proposed Business Combination to be automatically
converted immediately prior to the consummation of the Proposed Business Combination into a number of shares of Tango common stock at
the then-effective conversation rate as calculated in accordance with Tango&rsquo;s organizational documents), each share of Tango common
stock issued and outstanding immediately prior to the Effective Time shall be canceled and automatically converted into the right to
receive a number of shares of BCTG common stock equal in value to the quotient of the Merger Consideration divided by the fully diluted
capitalization of Tango (the &ldquo;Exchange Ratio&rdquo;) without interest. Each outstanding Tango option shall be assumed by BCTG and
automatically converted into an option to purchase such number of shares of BCTG&rsquo;s common stock, as adjusted based on the Exchange
Ratio. If any shares of Tango common stock issued and outstanding immediately prior to the Effective Time are shares of Tango restricted
stock, then the shares of BCTG common stock issued in exchange for such shares of Tango restricted stock shall to the same extent be
unvested and subject to the same repurchase option or risk of forfeiture as in effect immediately prior to the Effective Time, and the
certificates and/or book entries representing such shares of BCTG common stock shall accordingly be marked with appropriate legends.
No certificates or scrip representing fractional shares of BCTG&rsquo;s common stock will be issued pursuant to the consummation of the
Proposed Business Combination. Stock certificates evidencing the Merger Consideration shall bear restrictive legends as required by any
securities laws at the time of the closing of the Proposed Business Combination.</FONT></P>

<I>Debt&mdash;Debt with Conversion and Other Options (Subtopic&nbsp;470-20) and Derivatives and Hedging&mdash;Contracts in Entity&rsquo;s
Own Equity (Subtopic&nbsp;815-40): Accounting for Convertible Instruments and Contracts in an Entity&rsquo;s Own Equity</I>, which simplifies
accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement
conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings
per share calculation in certain areas. The ASU is effective for fiscal years beginning after December&nbsp;15, 2023, including interim
periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&nbsp;15, 2021
and adoption must be as of the beginning of our annual fiscal year. We are currently evaluating the impact of this standard on our financial
statements and related disclosures.</FONT></P>

We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised

the financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company
effective dates.</FONT></P>

we may not be required to, among other things, (i) provide an auditor&rsquo;s attestation report on our system of internal controls over
financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth
public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted

the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items
such as the correlation between executive compensation and performance and comparisons of the CEO&rsquo;s compensation to median employee
compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until
we are no longer an &ldquo;emerging growth company,&rdquo; whichever is earlier.</FONT></P>

Acquisition Corp. (&amp;#x201c;BCTG&amp;#x201d; or the &amp;#x201c;Company&amp;#x201d;) was incorporated as a Delaware corporation on May 21, 2020. The Company
was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other
similar business combination (a &amp;#x201c;Business Combination&amp;#x201d;) with one or more operating businesses or entities that it has not
yet selected (a &amp;#x201c;target business&amp;#x201d;). Although the Company is not limited to a particular industry or sector for purposes of
consummating a Business Combination, the Company intends to focus on businesses that have their primary operations located in North America
and Europe in the biotechnology industry. The Company has neither engaged in any operations nor generated revenue to date, other than

The Company is an &amp;#x201c;emerging growth company,&amp;#x201d; as defined in Section 2(a) of the Securities Act of 1933, as amended (the &amp;#x201c;Securities

April 13, 2021, BCTG entered into an agreement and plan of merger (as it may be amended and/or restated from time to time, the &amp;#x201c;Merger
Agreement&amp;#x201d;), by and among BCTG, BCTG Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of BCTG (&amp;#x201c;Merger
Sub&amp;#x201d;), and Tango Therapeutics, Inc. (&amp;#x201c;Tango&amp;#x201d;). The Merger Agreement provides for the merger of Merger Sub with and
into Tango, with Tango continuing as the surviving entity. Tango is a biotechnology company committed to discovering and delivering the
next generation of precision cancer medicines. See &amp;#x201c;The Proposed Business Combination&amp;#x201d; described below.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;All
Company activity for the period from May 21, 2020 (inception) through March 31, 2021 has been related to the Company&amp;#x2019;s formation
and initial public offering (&amp;#x201c;Initial Public Offering&amp;#x201d;) described below, and since the Initial Public Offering, the search
for a prospective initial Business Combination and the negotiation of the transactions related to the Proposed Business Combination.
The Company will not generate any operating revenue until after the completion of its initial Business Combination, at the earliest.
The Company generates non-operating income in the form of income earned on investments on cash and cash equivalents in the Trust Account
(as defined below). The Company has selected December 31 as its fiscal year end.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Company&amp;#x2019;s sponsor is BCTG Holdings, LLC, a Delaware limited liability company (the &amp;#x201c;Sponsor&amp;#x201d;). The registration statement
for the Company&amp;#x2019;s Initial Public Offering was declared effective on September 2, 2020. On September 8, 2020, the Company consummated
its Initial Public Offering of 16,675,000 shares of common stock (the &amp;#x201c;Public Shares&amp;#x201d;), including the 2,175,000 Public Shares
as a result of the underwriters&amp;#x2019; full exercise of their over-allotment option, at an offering price of $10.00 per Public Share,
generating gross proceeds of approximately $166.8 million, and incurring offering costs of approximately $9.6 million, inclusive of approximately
$5.8 million in deferred underwriting commissions (Note 5).&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Simultaneously
with the closing of the Initial Public Offering, the Company consummated the private placement (&amp;#x201c;Private Placement&amp;#x201d;) of 533,500
shares of common stock (the &amp;#x201c;Private Placement Shares&amp;#x201d;), at a price of $10.00 per Private Placement Share to the Sponsor,
generating gross proceeds of approximately $5.3 million (Note 4).&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; &quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Upon
the closing of the Initial Public Offering and the Private Placement, approximately $166.8 million ($10.00 per share), representing the
net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (&amp;#x201c;Trust
Account&amp;#x201d;) in the United States maintained by Continental Stock Transfer &amp;amp; Trust Company, as trustee, and will remain invested
only in U.S. government treasury bills, notes and bonds with a maturity of 185 days or less or in money market funds meeting certain
conditions under Rule 2a-7 under the Investment Company Act and which invest solely in U.S. Treasuries, until the earlier of: (i)&amp;#xa0;the
completion of a Business Combination and (ii)&amp;#xa0;the distribution of the Trust Account as described below.&amp;#xa0;&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Pursuant
to stock exchange listing rules, the Company&amp;#x2019;s initial Business Combination must be with one or more operating businesses or assets
with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting
discount held in trust and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement
in connection with its initial Business Combination. The terms of the Merger Agreement satisfy this requirement. However, the Company
will only complete an initial Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting
securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register
as an investment company under the Investment Company Act.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Company&amp;#x2019;s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering
and the sale of Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward
consummating a Business Combination. Furthermore, there is no assurance that the Company will be able to successfully complete a Business
Combination.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Company will provide the holders of Public Shares (the &amp;#x201c;Public Stockholders&amp;#x201d;) with the opportunity to redeem all or a portion
of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve
the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of
a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will
be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be
$10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company
to pay its tax obligations). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be
reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). In such case, the
Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation
of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is
not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will,
pursuant to the amended and restated Certificate of Incorporation which was adopted by the Company in connection with the Initial Public
Offering (the &amp;#x201c;Amended and Restated Certificate&amp;#x201d;), conduct the redemptions pursuant to the tender offer rules of the U.S.
Securities and Exchange Commission (the &amp;#x201c;SEC&amp;#x201d;), and file tender offer documents with the SEC prior to completing a Business
Combination. If, however, a stockholder approval of the transactions is required by law, or the Company decides to obtain stockholder
approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to
the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares
irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with
a Business Combination, the holders of the Founder Shares prior to the Initial Public Offering (the &amp;#x201c;Initial Stockholders&amp;#x201d;)
have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering
in favor of a Business Combination. In addition, the Initial Stockholders have agreed to waive their redemption rights with respect to
their Founder Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company has agreed
not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;If
the Company holds a stockholder vote or there is a tender offer for shares in connection with an initial Business Combination, a stockholder
will have the right to redeem such holder&amp;#x2019;s Public Shares for an amount in cash equal to such holder&amp;#x2019;s pro rata share of
the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination,
including interest not previously released to the Company to pay its franchise and income taxes. As a result, such common stock has been
recorded at redemption amount and classified as temporary equity, in accordance with the Financial Accounting Standard Board (&amp;#x201c;FASB&amp;#x201d;),
Accounting Standard Codification (&amp;#x201c;ASC&amp;#x201d;) 480, &amp;#x201c;Distinguishing Liabilities from Equity.&amp;#x201d; The amount in the Trust
Account is initially anticipated to be $10.00 per Public Share.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Notwithstanding
the foregoing, the Company&amp;#x2019;s Amended and Restated Certificate provides that a Public Stockholder, together with any affiliate of
such stockholder or any other person with whom such stockholder is acting in concert or as a &amp;#x201c;group&amp;#x201d; (as defined under Section
13 of the Securities Exchange Act of 1934, as amended (the &amp;#x201c;Exchange Act&amp;#x201d;)), will be restricted from redeeming its shares
with respect to more than an aggregate of 20% or more of the shares of common stock sold in the Initial Public Offering, without the
prior consent of the Company.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Company&amp;#x2019;s Sponsor, executive officers, and directors have agreed not to propose an amendment to the Company&amp;#x2019;s Amended and
Restated Certificate that would affect the substance or timing of the Company&amp;#x2019;s obligation to provide for the redemption of its
Public Shares in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business
Combination, unless the Company provides the Public Stockholders with the opportunity to redeem their shares of common stock in conjunction
with any such amendment.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;If
a Business Combination has not been consummated within 24 months from the closing of the Initial Public Offering, or September 8, 2022
(the &amp;#x201c;Combination Period&amp;#x201d;) and stockholders do not approve an amendment to the amended and restated certificate of incorporation
to extend this date), the Company 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 and (iii) as promptly as reasonably
possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate,
subject (in the case of (ii) and (iii) above) to the Company&amp;#x2019;s obligations under Delaware law to provide for claims of creditors
and the requirements of other applicable law.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Initial Stockholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete
a Business Combination within the Combination Period. However, if the Initial Stockholders should acquire Public Shares in or after the
Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares
if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights
to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business
Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account
that will be available to fund the redemption of the Company&amp;#x2019;s Public Shares. In the event of such distribution, it is possible
that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00
per share initially held in the Trust Account.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;The
Company will seek to have all third parties (other than the Company&amp;#x2019;s independent registered public accounting firm) and any prospective
target businesses enter into valid and enforceable agreements with the Company waiving any right, title, interest or claim of any kind
they may have in or to any monies held in the Trust Account. Nevertheless, there is no guarantee that vendors, service providers and
prospective target businesses will execute such agreements. The Company&amp;#x2019;s insiders have agreed that they will be jointly and severally
liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective
target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account
to below $10.00 per Public Share, except as to any claims by a third party who executed a valid and enforceable agreement with the Company
waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to
any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities
under the Securities Act. However, the Company&amp;#x2019;s insiders may not be able to satisfy their indemnification obligations. Moreover,
the Company&amp;#x2019;s insiders will not be liable to the Public Stockholders and instead will only have liability to the Company.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;&lt;b&gt;&lt;i&gt;Proposed

April 13, 2021, BCTG Acquisition Corp., a Delaware corporation (&amp;#x201c;BCTG&amp;#x201d;), entered into an agreement and plan of merger (as

Delaware corporation and a wholly-owned subsidiary of BCTG (&amp;#x201c;Merger Sub&amp;#x201d;), and Tango Therapeutics, Inc. (&amp;#x201c;Tango&amp;#x201d;).
Pursuant to the Merger Agreement, at the closing of the transactions contemplated thereby, Merger Sub will merge with and into Tango
(the &amp;#x201c;Merger&amp;#x201d;) with Tango surviving the merger as a wholly-owned subsidiary of BCTG (the &amp;#x201c;Proposed Business Combination&amp;#x201d;).
In addition, in connection with the consummation of the Proposed Business Combination, BCTG will be renamed &amp;#x201c;Tango Therapeutics,

preferred stock that is issued and outstanding immediately prior to the consummation of the Proposed Business Combination to be automatically
converted immediately prior to the consummation of the Proposed Business Combination into a number of shares of Tango common stock at
the then-effective conversation rate as calculated in accordance with Tango&amp;#x2019;s organizational documents), each share of Tango common
stock issued and outstanding immediately prior to the Effective Time shall be canceled and automatically converted into the right to
receive a number of shares of BCTG common stock equal in value to the quotient of the Merger Consideration divided by the fully diluted
capitalization of Tango (the &amp;#x201c;Exchange Ratio&amp;#x201d;) without interest. Each outstanding Tango option shall be assumed by BCTG and
automatically converted into an option to purchase such number of shares of BCTG&amp;#x2019;s common stock, as adjusted based on the Exchange
Ratio. If any shares of Tango common stock issued and outstanding immediately prior to the Effective Time are shares of Tango restricted
stock, then the shares of BCTG common stock issued in exchange for such shares of Tango restricted stock shall to the same extent be
unvested and subject to the same repurchase option or risk of forfeiture as in effect immediately prior to the Effective Time, and the
certificates and/or book entries representing such shares of BCTG common stock shall accordingly be marked with appropriate legends.
No certificates or scrip representing fractional shares of BCTG&amp;#x2019;s common stock will be issued pursuant to the consummation of the

for the issuance of the Founder Shares (as defined in Note 4), the loan under the certain promissory notes from the Company to the Sponsor
of approximately $127,000 (see Note 4) to the Company to cover for offering costs in connection with the Initial Public Offering, and
net proceeds from the consummation of the Private Placement not held in the Trust Account. The Company fully repaid the promissory notes
on September 10, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Company&amp;#x2019;s
officers, directors and initial stockholders may, but are not obligated to, provide the Company Working Capital Loans (see Note 4). However,
in the Merger Agreement, we have covenanted not to enter into any such arrangements . accordingly, as of March 31, 2021, there were no
amounts outstanding under any Working Capital Loans.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Based
on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs
through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will
be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates,
performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with
or acquire, and structuring, negotiating and consummating the Business Combination.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureAndSignificantAccountingPoliciesTextBlock>

Company is an &amp;#x201c;emerging growth company,&amp;#x201d; as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our
Business Startups Act of 2012 (the &amp;#x201c;JOBS Act&amp;#x201d;), and it may take advantage of certain exemptions from various reporting requirements
that are applicable to other public&amp;#xa0;companies that are not emerging growth companies including, but not limited to, not being required
to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced
disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements
of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously
approved.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; &quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Further,
Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting
standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do
not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting
standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with
the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application
dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time
private companies adopt the new or revised standard. This may make comparison of the Company&amp;#x2019;s financial statement with another
public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition
period difficult or impossible because of the potential differences in accounting standards used.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;&lt;b&gt;&lt;i&gt;Concentration

instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution,
which, at times, may exceed the Federal Depository Insurance Coverage limit of $250,000. As of March 31, 2021, the Company has not experienced

invest in U.S. government securities, or a combination thereof. The Company&amp;#x2019;s investments held in the Trust Account are classified
as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains
and losses resulting from the change in fair value of these securities are included in interest earned on investments held in the Trust

value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction
between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs
used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets
or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Company accounts for its common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 &amp;#x201c;Distinguishing
Liabilities from Equity.&amp;#x201d; Shares of common stock subject to mandatory redemption (if any) are classified as liability instruments
and are measured at fair value. Shares of conditionally redeemable common stock (including common stock that feature redemption rights
that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the
Company&amp;#x2019;s control) are classified as temporary equity. At all other times, shares of common stock are classified as stockholders&amp;#x2019;
equity. The Company&amp;#x2019;s common stock features certain redemption rights that are considered to be outside of the Company&amp;#x2019;s
control and subject to the occurrence of uncertain future events. Accordingly, at March 31, 2021 and December 31, 2020, 15,712,245 and
15,736,221 shares of common stock subject to possible redemption are presented as temporary equity, outside of the stockholders&amp;#x2019;

Company complies with the accounting and reporting requirements of Financial Accounting Standards Board Accounting Standard Codification,
or FASB ASC, 740, &amp;#x201c;Income Taxes,&amp;#x201d; which requires an asset and liability approach to financial accounting and reporting for
income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets
and liabilities are measured using enacted tax rates expected to apply to taxable income in the&amp;#xa0;years in which those temporary differences

positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not
to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized

loss per share, basic and diluted for Founder Shares for the three months ended March 31, 2021 is calculated by dividing the net loss

$242,000, by the weighted average number of non-redeemable common shares outstanding for the periods.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; &quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;&lt;b&gt;&lt;i&gt;Recent

August 2020, the Financial Accounting Standards Board (&amp;#x201c;FASB&amp;#x201d;) issued Accounting standards update (&amp;#x201c;ASU&amp;#x201d;) 2020-06,
&lt;i&gt;Debt&amp;#x2014;Debt with Conversion and Other Options (Subtopic&amp;#xa0;470-20) and Derivatives and Hedging&amp;#x2014;Contracts in Entity&amp;#x2019;s
Own Equity (Subtopic&amp;#xa0;815-40): Accounting for Convertible Instruments and Contracts in an Entity&amp;#x2019;s Own Equity&lt;/i&gt;, which simplifies
accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement
conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings
per share calculation in certain areas. The ASU is effective for fiscal years beginning after December&amp;#xa0;15, 2023, including interim
periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&amp;#xa0;15, 2021
and adoption must be as of the beginning of the Company&amp;#x2019;s annual fiscal year. The Company is currently evaluating the impact of
this standard on its financial statements and related disclosures.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; &quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Management

to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting
standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do
not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting
standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with
the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application
dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time
private companies adopt the new or revised standard. This may make comparison of the Company&amp;#x2019;s financial statement with another
public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition
period difficult or impossible because of the potential differences in accounting standards used.&lt;/font&gt;&lt;/p&gt;</us-gaap:OrganizationConsolidationBasisOfPresentationBusinessDescriptionAndAccountingPoliciesTextBlock>

income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets
to the amount expected to be realized.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;FASB
ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax
positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not
to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized
tax benefits as income tax expense.&lt;/font&gt;&lt;/p&gt;</us-gaap:IncomeTaxPolicyTextBlock>

August 2020, the Financial Accounting Standards Board (&amp;#x201c;FASB&amp;#x201d;) issued Accounting standards update (&amp;#x201c;ASU&amp;#x201d;) 2020-06,
&lt;i&gt;Debt&amp;#x2014;Debt with Conversion and Other Options (Subtopic&amp;#xa0;470-20) and Derivatives and Hedging&amp;#x2014;Contracts in Entity&amp;#x2019;s
Own Equity (Subtopic&amp;#xa0;815-40): Accounting for Convertible Instruments and Contracts in an Entity&amp;#x2019;s Own Equity&lt;/i&gt;, which simplifies
accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement
conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings
per share calculation in certain areas. The ASU is effective for fiscal years beginning after December&amp;#xa0;15, 2023, including interim
periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December&amp;#xa0;15, 2021
and adoption must be as of the beginning of the Company&amp;#x2019;s annual fiscal year. The Company is currently evaluating the impact of
this standard on its financial statements and related disclosures.&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; &quot;&gt;&lt;font style=&quot;font-family: Times New Roman, Times, Serif; font-size: 10pt&quot;&gt;Management

of the Business Combination into additional private placement shares at a conversion price of $10.00 per share. If the Company does not
complete a Business Combination, the loans would not be repaid. Such private placement shares would be identical to the Private Placement
Shares. However, in the Merger Agreement, we have covenanted not to enter into any such arrangements . Accordingly, to date, the Company

Acquisition Corp. (&#x201c;BCTG&#x201d; or the &#x201c;Company&#x201d;) was incorporated as a Delaware corporation on May 21, 2020. The Company
was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other
similar business combination (a &#x201c;Business Combination&#x201d;) with one or more operating businesses or entities that it has not
yet selected (a &#x201c;target business&#x201d;). Although the Company is not limited to a particular industry or sector for purposes of
consummating a Business Combination, the Company intends to focus on businesses that have their primary operations located in North America
and Europe in the biotechnology industry. The Company has neither engaged in any operations nor generated revenue to date, other than
searching for a target business and the negotiation of the transactions related to the Proposed Business Combination (as defined below).
The Company is an &#x201c;emerging growth company,&#x201d; as defined in Section 2(a) of the Securities Act of 1933, as amended (the &#x201c;Securities
Act&#x201d;), as modified by the Jumpstart our Business Startups Act of 2012 (the &#x201c;JOBS Act&#x201d;).</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">On
April 13, 2021, BCTG entered into an agreement and plan of merger (as it may be amended and/or restated from time to time, the &#x201c;Merger
Agreement&#x201d;), by and among BCTG, BCTG Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of BCTG (&#x201c;Merger
Sub&#x201d;), and Tango Therapeutics, Inc. (&#x201c;Tango&#x201d;). The Merger Agreement provides for the merger of Merger Sub with and
into Tango, with Tango continuing as the surviving entity. Tango is a biotechnology company committed to discovering and delivering the
next generation of precision cancer medicines. See &#x201c;The Proposed Business Combination&#x201d; described below.</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">All

and initial public offering (&#x201c;Initial Public Offering&#x201d;) described below, and since the Initial Public Offering, the search
for a prospective initial Business Combination and the negotiation of the transactions related to the Proposed Business Combination.
The Company will not generate any operating revenue until after the completion of its initial Business Combination, at the earliest.
The Company generates non-operating income in the form of income earned on investments on cash and cash equivalents in the Trust Account
(as defined below). The Company has selected December 31 as its fiscal year end.</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The

for the Company&#x2019;s Initial Public Offering was declared effective on September 2, 2020. On September 8, 2020, the Company consummated
its Initial Public Offering of 16,675,000 shares of common stock (the &#x201c;Public Shares&#x201d;), including the 2,175,000 Public Shares
as a result of the underwriters&#x2019; full exercise of their over-allotment option, at an offering price of $10.00 per Public Share,
generating gross proceeds of approximately $166.8 million, and incurring offering costs of approximately $9.6 million, inclusive of approximately
$5.8 million in deferred underwriting commissions (Note 5).</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Simultaneously

shares of common stock (the &#x201c;Private Placement Shares&#x201d;), at a price of $10.00 per Private Placement Share to the Sponsor,

the closing of the Initial Public Offering and the Private Placement, approximately $166.8 million ($10.00 per share), representing the
net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (&#x201c;Trust

only in U.S. government treasury bills, notes and bonds with a maturity of 185 days or less or in money market funds meeting certain
conditions under Rule 2a-7 under the Investment Company Act and which invest solely in U.S. Treasuries, until the earlier of: (i)&#xa0;the

to stock exchange listing rules, the Company&#x2019;s initial Business Combination must be with one or more operating businesses or assets
with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting
discount held in trust and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement
in connection with its initial Business Combination. The terms of the Merger Agreement satisfy this requirement. However, the Company
will only complete an initial Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting
securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register
as an investment company under the Investment Company Act.</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
Company&#x2019;s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering
and the sale of Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward
consummating a Business Combination. Furthermore, there is no assurance that the Company will be able to successfully complete a Business
Combination.</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The

of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve
the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of
a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will
be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be
$10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company
to pay its tax obligations). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be
reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). In such case, the
Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation
of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is
not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will,
pursuant to the amended and restated Certificate of Incorporation which was adopted by the Company in connection with the Initial Public
Offering (the &#x201c;Amended and Restated Certificate&#x201d;), conduct the redemptions pursuant to the tender offer rules of the U.S.
Securities and Exchange Commission (the &#x201c;SEC&#x201d;), and file tender offer documents with the SEC prior to completing a Business
Combination. If, however, a stockholder approval of the transactions is required by law, or the Company decides to obtain stockholder
approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to
the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares
irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with
a Business Combination, the holders of the Founder Shares prior to the Initial Public Offering (the &#x201c;Initial Stockholders&#x201d;)
have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering
in favor of a Business Combination. In addition, the Initial Stockholders have agreed to waive their redemption rights with respect to
their Founder Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company has agreed
not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.</font></p><br/><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><font style="font-family: Times New Roman, Times, Serif; font-size: 10pt">If

the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination,
including interest not previously released to the Company to pay its franchise and income taxes. As a result, such common stock has been

Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares
if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights
to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business
Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account
that will be available to fund the redemption of the Company&#x2019;s Public Shares. In the event of such distribution, it is possible
that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00

they may have in or to any monies held in the Trust Account. Nevertheless, there is no guarantee that vendors, service providers and
prospective target businesses will execute such agreements. The Company&#x2019;s insiders have agreed that they will be jointly and severally
liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective

any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities

Delaware corporation and a wholly-owned subsidiary of BCTG (&#x201c;Merger Sub&#x201d;), and Tango Therapeutics, Inc. (&#x201c;Tango&#x201d;).
Pursuant to the Merger Agreement, at the closing of the transactions contemplated thereby, Merger Sub will merge with and into Tango

be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates,
performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with

standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with
the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application
dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time
private companies adopt the new or revised standard. This may make comparison of the Company&#x2019;s financial statement with another

standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with
the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected
not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application
dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time
private companies adopt the new or revised standard. This may make comparison of the Company&#x2019;s financial statement with another
public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition
period difficult or impossible because of the potential differences in accounting standards used.</font></p><span></span>
