<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Using our proprietary technology and design and
engineering expertise, we modify&nbsp;code-engineered&nbsp;cargo shipping containers and purpose-built modules for use for safe and sustainable
commercial, industrial and residential building construction. Rather than consuming new steel and lumber, our proprietary technology
and design and engineering expertise allows for the redesign, repurpose and conversion of heavy-gauge steel cargo shipping containers
into SGBlocks&trade;, which are safe green building blocks for commercial, industrial, and residential building construction.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Our business model originally was a&nbsp;project-based
construction&nbsp;model&nbsp;pursuant to which we were responsible for the design, construction and sale of finished products&nbsp;that
incorporated our technology to customers throughout the United States primarily in the multi-family housing, restaurant, military and
education industries. From October 2019 to June 2021, our business model for residential building construction became a royalty-fee model
established under a five-year exclusive license with CPF MF 2019-1 LLC (&ldquo;CPF&rdquo;) pursuant to which CPF received an exclusive
license for our proprietary technology for residential use, including, without limitation, single-family residences and multi-family
residences, but specifically excluding military housing. Our Ridge Avenue Project, a residential housing project in Atlanta, was also
excluded from the license to CPF.&nbsp;&nbsp;In June 2021, we terminated the license to CPF and recommenced our original project-based
business model&nbsp;pursuant to which we design, construct and sell finished products&nbsp;to customers throughout the United States.</P>

and began focusing on the medical projects when we entered into the COVID-19 diagnostic market through the distribution of COVID-19 diagnostic
tests.&nbsp;&nbsp;We have subsequently entered into additional collaborations for the distribution of diagnostic tests as well as collaborations
for the use of our modular technology for the building&nbsp;of medical test centers that include COVID-19 testing.&nbsp;During 2020,&nbsp;we&nbsp;entered
into a joint venture, and have begun, to provide clinical lab testing, as well as test kit sales related to a separate distributer agreement.&nbsp;</P>

all the assets of Echo, a Texas limited liability company. Echo is a container/modular manufacturer based in Durant, Oklahoma specializing
in the design and construction of permanent modular and temporary modular buildings and was one of our key supply chain partners. Echo
catered to the military, education, administration facilities, healthcare, government, commercial and residential customers. This acquisition
has allowed us to expand our reach for our Modules and offers us an opportunity to vertically integrate a large portion of our cost of
goods sold, as well as increase margins, productivity and efficiency in the areas of design, estimating, manufacturing and delivery.</P>

the exercise of profits interest units, warrants or other rights that are either immediately exercisable or exercisable on or before January
8 2022, which is approximately 60 days after the date of this prospectus. These shares are deemed to be outstanding and beneficially owned
by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not
treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Registrant is incorporated under the laws
of the State of Delaware. Subsection (a) of Section 145 of the General Corporation Law of the State of Delaware (the &ldquo;DGCL&rdquo;)
empowers a corporation to indemnify any person who was or is a party or who is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right
of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or
was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, against expenses (including attorneys&rsquo; fees), judgments, fines and amounts paid in settlement actually
and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner
the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe the person&rsquo;s conduct was unlawful.</P>

to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit

set forth above, against expenses (including attorneys&rsquo; fees) actually and reasonably incurred by the person in connection with
the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be
in or not opposed to the best interests of the corporation, except that no indemnification shall be made in respect of any claim, issue
or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court
of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the
Court of Chancery or such other court shall deem proper.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Section 145 further provides that to the extent
a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding
referred to in subsections (a) and (b) of Section 145, or in defense of any claim, issue or matter therein, such person shall be indemnified
against expenses (including attorneys&rsquo; fees) actually and reasonably incurred by such person in connection therewith; that indemnification
provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the
indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who
has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person&rsquo;s heirs, executors and administrators.
Section 145 also empowers the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred
by such person in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify
such person against such liabilities under Section 145.</P>

we entered into a Securities Purchase Agreement (the &ldquo;Purchase Agreement&rdquo;) with an investor, pursuant to which we issued to
the investor a senior secured convertible debenture in the principal amount of $480,770 (the &ldquo;Debenture&rdquo;) for proceeds of

to existing security interests and exceptions. We had the right to redeem all or a portion of the outstanding principal of the Debenture
(i) prior to the maturity date without interest and with no conversion by the investor and (ii) after the maturity date at a premium of
120%, and with interest accruing at 24% from the maturity date. The Debenture was convertible into shares of our common stock only upon
(i) the occurrence of an Event of Default (as defined in the Debenture) or (ii) at maturity in the event any principal remains outstanding,
at a conversion price equal to the lower of (x) 67.5% of the lowest daily VWAPs of the common stock during the five consecutive trading
days immediately preceding the Event of Default or date of maturity or (y) if the Debenture was not fully paid as of the Maturity, the
lowest daily VWAP during the ten (10) consecutive trading days immediately preceding the date of the applicable Conversion, and based
on a conversion amount determined by the product of (x) the portion of the principal and accrued interest to be converted and (y) 120%

daily VWAP during the ten (10) consecutive Trading Days immediately preceding the date of the applicable Conversion; subject to certain
