Item 3.02. Unregistered Sales of Equity Securities

The information disclosed under Item 8.01 of this Current Report on

Form 8-K is incorporated by reference into this Item 3.02 to the extent required herein. The shares of Pubco Common Stock (as defined

below) issuable in connection with the PIPE Financing (as defined below) will not be registered under the Securities Act of 1933, as amended

(the “Securities Act”), in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities

Act.

Item 8.01. Other Events.

As previously disclosed by Archimedes Tech SPAC

Partners II Co., a Cayman Islands exempted company (“ATII”), in its Current Report on Form 8-K filed on April 20, 2026

with the U.S. Securities and Exchange Commission (the “SEC”), on April 20, 2026, ATII, ATII Holdings Inc., a Delaware

corporation and a wholly-owned subsidiary of ATII (“Pubco”), ATII Merger Sub Inc., a Delaware corporation and a wholly-owned

subsidiary of ATII (“Merger Sub I”), ATII Merger Sub II, LLC, a Delaware limited liability company and a wholly-owned

subsidiary of ATII (“Merger Sub II”) and Forge Nano, Inc., a Delaware corporation (“Forge Nano”),

entered into an Agreement and Plan of Merger (the “Merger Agreement”) relating to the proposed business combination

by and among the parties thereto (the transactions contemplated under the Merger Agreement, collectively, the “proposed business

combination”).

On July 14, 2026, Forge Nano issued a press release

announcing that Pubco, Forge Nano and ATII (solely with respect to limited provisions therein) have entered into subscription agreements

(each, a “Subscription Agreement,” and the transactions contemplated under the Subscription Agreements, collectively,

the “PIPE Financing”) with certain investors (the “PIPE Investors”), pursuant to which Pubco will,

substantially concurrently with, and contingent upon, the consummation of the proposed business combination, sell to the PIPE Investors

an aggregate of 2,300,000 shares of the common stock, par value $0.0001 per share, of Pubco (each, a share of “Pubco Common Stock,”

and the Pubco Common Stock issuable pursuant to the PIPE Financing, the “PIPE Shares”), in a private placement for

a purchase price of $10.00 per PIPE Share. The PIPE Financing is expected to close in conjunction with the closing of the proposed business

combination and generate gross proceeds of approximately $23,000,000. A copy of the press release is attached as Exhibit 99.1 and is incorporated

herein by reference.

The closing of the PIPE Financing (the “PIPE

Closing”) is conditioned upon, among other things, (i) the substantially concurrent closing of the proposed business combination

and (ii) the accuracy of all representations and warranties of Pubco and Forge Nano in the Subscription Agreements (subject to certain

bring-down standards). The Subscription Agreements contain customary representations, warranties and agreements by Pubco, Forge Nano and

the PIPE Investors, additional customary conditions to closing, indemnification obligations of Pubco, including for liabilities arising

under the Securities Act, other obligations of the parties, and termination provisions.

Pubco has agreed that within thirty (30) days

of the date of the closing of the proposed business combination (the “Closing Date”), Pubco will file (at its sole

cost and expense) with the SEC a registration statement on Form S-3 or Form S-1 or any similar or successor long form registration statement

(the “PIPE Registration Statement”) registering the resale of the Registrable Securities (as defined in the Subscription

Agreements), and will use its commercially reasonable efforts to have such PIPE Registration Statement declared effective as soon as practicable

after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days following the Closing Date (or ninety (90) calendar

days following the Closing Date if the SEC notifies Pubco that it will “review” such PIPE Registration Statement) and (ii)

five (5) business days after Pubco is notified by the SEC that such PIPE Registration Statement will not be “reviewed” or

will not be subject to further review, subject to customary exceptions. Pursuant to the Subscription Agreements, Pubco will cause such

PIPE Registration Statement to remain effective until the earliest of: (i) such time as when all of each PIPE Investor’s securities

included therein cease to be Registrable Securities, (ii) such time as when all of such PIPE Investor’s Registrable Securities included

in such PIPE Registration Statement have actually been sold and (iii) three (3) years from the Closing Date.

The Subscription Agreements also provide that

if, during the twelve (12)-month period following the Closing Date, Pubco issues shares of Pubco Common Stock (other than certain Exempt

Issuances (as defined in the Subscription Agreements) which include, among other exemptions, issuances to certain specified investors

in an aggregate amount up to $60,000,000), on terms that, in each PIPE Investor’s good faith determination, are more favorable in

any material respect than those provided to such PIPE Investor in the PIPE Financing (such terms, the “PIPE Financing Terms”),

then Pubco shall be obligated to adjust the PIPE Financing Terms so that the PIPE Financing Terms are no less favorable than the terms

of such subsequent issuance(s).

The foregoing description of the Subscription

Agreements is qualified in its entirety by reference to the full text of the Subscription Agreements, a copy of the form of which is filed

as Exhibit 99.2 to this Current Report on Form 8-K and incorporated herein by reference.

Important Information and Where to Find It

Additional information about the proposed business combination, including

a copy of the Merger Agreement, has been filed by ATII in a Current Report on Form 8-K with the SEC. In connection with the proposed business

combination, Pubco and Forge Nano have filed documents with the SEC, including a registration statement on Form S-4 (as may be amended

from time to time, the “Registration Statement”), which includes a proxy statement of ATII and a prospectus of Pubco,

relating to the proposed business combination. After the SEC declares the Registration Statement effective, the Registration Statement

will be mailed to ATII’s shareholders in connection with the proposed business combination. This Current Report on Form 8-K is not

a substitute for the proxy statement/prospectus contained in the Registration Statement or any other document that may be filed by Pubco

with the SEC. BEFORE MAKING ANY VOTING DECISION, INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE REGISTRATION STATEMENT AND ANY OTHER

DOCUMENTS FILED OR TO BE FILED WITH THE SEC IN CONNECTION WITH THE PROPOSED BUSINESS COMBINATION OR INCORPORATED BY REFERENCE IN THE REGISTRATION

STATEMENT BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED BUSINESS COMBINATION. Any vote in respect of resolutions to be

proposed at ATII’s extraordinary general meeting to approve the proposed business combination or other responses in relation to

the related proposed transactions should be made only on the basis of the information contained in the Registration Statement. Investors

and security holders may obtain free copies of these documents (as they become available) and other related documents filed with the SEC

at the SEC’s website at www.sec.gov or by directing a request to: Archimedes Tech SPAC Partners II Co., 2093 Philadelphia Pike #1968,

Claymont, DE 19703.

officers and other members of management and employees, under SEC rules, may be deemed to be “participants” in the solicitation

of proxies from shareholders of ATII in favor of the proposed business combination. Information about ATII’s directors and officers

is set forth in ATII’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “Annual Report on Form

10-K”), which was filed with the SEC on March 4, 2026, and ATII’s other filings with the SEC. Additional information concerning

the interests of ATII’s participants in the solicitation, which may, in some cases, be different than those of ATII’s shareholders

generally, are set forth in the Registration Statement relating to the proposed business combination. These documents are available free

of charge at the SEC’s web site at www.sec.gov.

is not intended to and does not constitute, or form part of, an offer, invitation or the solicitation of an offer or invitation to purchase,

otherwise acquire, subscribe for, sell or otherwise dispose of any securities, or the solicitation of any vote or approval in any jurisdiction,

pursuant to the proposed business combination or otherwise, nor shall there be any sale, issuance or transfer of securities in any jurisdiction

in contravention of applicable law. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section

10 of the Securities Act.

Forward-Looking Statements

This Current Report on Form 8-K includes forward-looking information

about, among other topics, the proposed business combination. All statements, other than statements of present or historical fact, included

in this Current Report on Form 8-K regarding the proposed business combination, ATII’s, Pubco’s and Forge Nano’s ability

to consummate the proposed business combination, the benefits of the proposed business combination and the combined company’s future

financial performance, as well as the combined company’s strategy, future operations, estimated financial position, estimated revenues

and losses, projected costs, prospects, plans and objectives of management, are forward-looking statements. When used in this Current

Report on Form 8-K, the words “could,” “should,” “will,” “may,” “believe,”

“anticipate,” “intend,” “estimate,” “expect,” “project,” the negative of such

terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain

such identifying words. These forward-looking statements are based on the current expectations and assumptions of ATII’s, Pubco’s

and Forge Nano’s management about future events and are based on currently available information as to the outcome and timing of

future events. Except as otherwise required by applicable law, ATII, Pubco and Forge Nano disclaim any duty to update any forward-looking

statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date

of this Current Report on Form 8-K.

ATII, Pubco and Forge Nano caution you that these forward-looking statements

are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of ATII,

Pubco or Forge Nano. Risks and uncertainties include, among other things: (i) risks related to the occurrence of any event, change or

other circumstances that could delay the proposed business combination or give rise to the termination of the agreements related thereto;

(ii) risks related to the outcome of any legal proceedings that may be instituted against ATII, Pubco or Forge Nano following announcement

of the transactions; (iii) risks related to the inability to complete the proposed business combination due to the failure to obtain approval

of the shareholders of ATII, Pubco and Forge Nano, or other conditions to closing in the Merger Agreement; (iv) the risk that the proposed

business combination disrupts ATII’s, Pubco’s or Forge Nano’s current plans and operations as a result of the announcement

of the transactions; (v) risks related to Forge Nano’s ability to realize the anticipated benefits of the proposed business combination,

which may be affected by, among other things, competition and the ability of Forge Nano to grow and manage growth profitably following

the proposed business combination; (vi) risks related to costs related to the proposed business combination; (vii) risks related to changes

in applicable laws or regulations; (viii) risks related to Forge Nano’s ability to successfully develop and deploy new technologies

to address the needs of its customers; (ix) risks related to the effects of competition on Forge Nano’s business, financial condition

and results of operations; (x) risks related to the availability and cost of the raw materials necessary for the production of Forge Nano’s

products; (xi) risks related to Forge Nano’s ability to meet the specifications and requirements of its customers or adequately

provide them with effective support and services; (xii) risks related to delays in the construction and operation of production facilities;

(xiii) risks related to intellectual property infringement, data protection, and other losses; (xiv) risks related to the amount of redemption

requests made by ATII’s public shareholders; (xv) risks related to the combined company’s ability to operate effectively as

a public company, including its ability to implement controls and procedures required for public companies following the business combination;

(xvi) risks related to changes in domestic and foreign business, market, financial, political and legal conditions; (xvii) risks related

to the possibility that ATII, Pubco or Forge Nano may be adversely affected by other economic, business, and/or competitive factors; and

(xviii) other risks discussed in ATII’s Annual Report on Form 10-K and that are presented in the Registration Statement. There may

be additional risks that ATII, Pubco or Forge Nano presently do not know or that ATII, Pubco or Forge Nano currently believe are immaterial

that could also cause actual results to differ from those contained in the forward-looking statements. Should one or more of the risks

or uncertainties described in this Current Report on Form 8-K, or should underlying assumptions prove incorrect, actual results and plans

could differ materially from those expressed or implied in any forward-looking statements. Additional information concerning these and

other factors that may impact the operations and projections discussed herein can be found in ATII’s periodic filings with the SEC,

including ATII’s Annual Report on Form 10-K and the Registration Statement. These SEC filings are available free of charge on the

SEC’s website at www.sec.gov.

You should carefully consider the foregoing factors and the other risks

and uncertainties that affect the businesses of ATII, Pubco and Forge Nano described in the “Risk Factors” and “Forward-Looking

Statements” sections of the Registration Statement and other documents filed or to be filed by any of them from time to time with

the SEC, all of which are available at www.sec.gov. These filings identify and address other important risks and uncertainties that could

cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements

speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and ATII, Pubco

and Forge Nano assume no obligation to, and do not intend to, update or revise these forward-looking statements, whether as a result of

new information, future events, or otherwise, unless required by law. None of ATII, Pubco or Forge Nano gives any assurance that it will

achieve its expectations.

Exhibit 99.1

Forge Nano Secures Additional $23 Million in

PIPE Financing at $10.00 Per Share, Closes Series D with Samsung Investment Ahead of Public Listing

· New commitment brings total PIPE financing to $123 million as Forge Nano continues its path towards its NASDAQ listing

· All $23 million of new PIPE commitments priced at $10.00 per share

· Samsung SDI commits $20 million to Forge Nano, including $10 million in Forge Nano's PIPE financing

· Forge Nano successfully closes its Series D at $97 million, rounding out its pre-IPO capital formation

· Forge Nano's public listing would deliver over $367 million in pro forma cash, assuming no redemptions - combining approximately $244

million in trust with $123 million in PIPE commitments

DENVER

– July 14 – Forge Nano, Inc., a leading U.S.-based semiconductor equipment and advanced

materials company pioneering Atomic Layer Deposition (“ALD”) technology for artificial intelligence (“AI”)-era

chip manufacturing and defense battery applications, which has signed an agreement to merge with Archimedes Tech SPAC Partners II Co.

(“Archimedes II”) (NASDAQ: ATII), today announced an additional $23 million of committed PIPE financing ahead of its expected

public listing on NASDAQ. All $23 million of the incremental PIPE financing was priced at $10.00 per share, increasing total PIPE commitments

to $123 million.

The additional financing includes a $20 million strategic investment

from Samsung SDI, comprised of $10 million in the Company's PIPE financing and $10 million in Forge Nano's Series D financing. Horizons

Ventures has also participated in the Company’s PIPE financing. Forge Nano has also successfully closed its Series D at $97

million, rounding out its pre-IPO capital formation.

Assuming no shareholder redemptions, Forge Nano’s public listing

would deliver over $367 million in pro forma cash comprised of the $123 million PIPE and $244 million in Archimedes II cash in trust.

Upon closing of the business combination, Forge Nano expects that its substantial capital will accelerate commercialization of the Company’s

ALD semiconductor equipment platform and expand domestic manufacturing of advanced lithium-ion battery materials.

"These additional commitments represent a strong vote of confidence

from both strategic and financial investors as we prepare to become a public company," said Paul Lichty, CEO of Forge Nano. "Samsung

SDI's investment reinforces our shared vision for strengthening the domestic battery supply chain, while the new PIPE commitments at $10.00

per share demonstrate continued investor conviction in Forge Nano's long-term growth strategy. We believe we are exceptionally well positioned

to scale manufacturing, execute on our commercial pipeline and meet growing demand across the semiconductor and defense battery markets."

The business combination with Archimedes II is expected to close in

the second half of 2026, subject to approval by Archimedes II shareholders and the satisfaction of customary closing conditions.

(10) business days following such issuance, provide the Subscriber with written notice thereof (the “MFN Notice”),

good faith that the terms, rights, or privileges provided to such New Securities in connection with the issuance of such New Securities

(collectively, the “New Security Terms”) are more favorable in any material respect than those provided to the Securities

or to the Subscriber in connection with the Closing (collectively, the “Subscription Terms”), the Subscriber shall

or exchangeable for or convertible into shares of Common Stock issued and outstanding on the date of the Transaction Closing (the “Closing

Date”), provided that such securities have not been amended since the Closing Date to increase the number of such securities

or to decrease the exercise price, exchange price or conversion price of such securities (other than in connection with share consolidations,

not more favorable to the holder thereof than the anti-dilution and similar provisions set forth herein) or to extend the term of such

securities, (c) any securities of the Company at or prior to the Closing Date to the investors listed on Schedule B hereto, in each

case including any “affiliate” (as defined in Rule 144 under the Securities Act) thereof, for aggregate proceeds not

exceeding $60 million, (d) the underlying shares, and (e) securities issued pursuant to any merger, acquisition or strategic

transaction or partnership, provided that (i) such securities are issued as “restricted securities” (as defined in Rule 144)

or are issued pursuant to an effective registration statement pursuant to the Securities Act and (ii) any such issuance shall only

be to a person (or to direct or indirect the equityholders and/or debtholders of a person) which is, itself or through its subsidiaries,

an operating company or an owner of an asset that the Company determines in good faith is similar, reasonably related, incidental or

ancillary to the then business or operations of the Company and its subsidiaries or their assets or is otherwise to be used or useful

in such business or operations, but any such Exempt Issuance shall not include a transaction in which the Company is issuing securities

results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit

adjustments. As of the date hereof, there are no outstanding or unresolved comments in comment letters from the Staff of the Commission

with respect to any of the SEC Documents.

2.2.12      Other

than the Other Subscription Agreements, the Transaction Agreement and any other agreement expressly contemplated by the Transaction Agreement,

neither the Company nor the SPAC has entered into any side letter or similar agreement with any Other Subscriber or any other investor

in connection with such Other Subscriber’s or investor’s investment in the Company. No Other Subscription Agreement includes

a price per Security different from this Subscription Agreement or other terms, rights or conditions that are more advantageous (economically

or otherwise) in any material respect to any such Other Subscriber than Subscriber hereunder, and such Other Subscription Agreements

have not been amended or modified in any material respect following the date of this Subscription Agreement in any manner that materially

benefits the Other Subscriber thereunder unless Subscriber has been granted the same benefits.

2.2.13      The

Company is not, and immediately after receipt of payment for the Securities will not be, an “investment company” within the

meaning of the Investment Company Act of 1940, as amended.

2.2.14      As

of the date of this Agreement the Company has not received any written communication from any Authority that alleges that the Company

is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation

would not, individually or in the aggregate, be reasonably expected to have a Company Material Adverse Effect.

2.2.15      Except

for such matters as have not had and would not be reasonably expected to have, individually or in the aggregate, a Company Material Adverse

Effect, there is no (i) action, claim, inquiry, arbitration, investigation, litigation or other proceeding pending, or, to the knowledge

of the Company, threatened against the Company or (ii) judgment, decree, injunction, ruling or order of any Authority outstanding

against the Company.

2.2.16      Except

for discussions specifically regarding the offer and sale of the Securities and the Investor Presentation, the Company confirms that

neither it nor any other person acting on its behalf has provided Subscriber or its agents or counsel with any information that constitutes

or could reasonably be expected to constitute material, nonpublic information concerning the Company, the SPAC or any of their subsidiaries,

other than with respect to the Transaction and the transactions contemplated by this Subscription Agreement or the Other Subscription

Agreements. Except with respect to the Transaction and the transactions contemplated by this Subscription Agreement and the Other Subscription

Agreements, no event or circumstance has occurred which, under applicable law, rule or regulation, requires public disclosure or

announcement by the Company but which has not been so publicly disclosed.

2.2.17      [Reserved].

2.2.18      With

respect to the distribution of information to Subscriber (if a Foreign Purchaser) or any Other Subscriber that are Foreign Purchasers,

the Company has and will comply with the regulations associated with the CFIUS. Without limiting the foregoing, the Company represents,

warrants and agrees that it has not provided and does not intend to provide and will take measure to prevent the provision to any Foreign

Purchasers any (i) access to any material non-public technical information (as defined in 31 C.F.R. §801.208) in the possession

of the Company, or (ii) involvement, other than through the voting of shares, in substantive decision-making of the Company regarding

the use, development, acquisition or release of critical technology (as defined in 31 C.F.R §801.204).

2.3            Forge

Nano’s Representations, Warranties and Agreements. To induce Subscriber to purchase the Securities, Forge Nano hereby represents

and warrants to Subscriber and agrees with Subscriber as follows:

2.3.1        Forge

Nano is a corporation duly incorporated, validly existing and in good standing under the Laws of the State of Delaware, with the requisite

corporate power and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into,

deliver and perform its obligations under this Subscription Agreement, except where the failure to have such power or authority would

not, individually or in the aggregate, reasonably be expected to have a Forge Nano Material Adverse Effect (as defined below).

2.3.2        This

Subscription Agreement has been duly authorized, executed and delivered by Forge Nano and is a valid and binding obligation of Forge

Nano, enforceable against it in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency,

fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, and (ii) principles

of equity, whether considered at law or equity.

2.3.3        The

execution, delivery and performance of this Subscription Agreement (including compliance by Forge Nano with all of the provisions hereof),

the issuance and sale of the Securities and the consummation of the certain other transactions contemplated herein will not (i) conflict

with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation

or imposition of any lien, charge or encumbrance upon any of the property or assets of Forge Nano or any of its subsidiaries pursuant

to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Forge

Nano or any of its subsidiaries is a party or by which Forge Nano or any of its subsidiaries is bound or to which any of the property

or assets of Forge Nano or any of its subsidiaries is subject, which would, individually or in the aggregate, reasonably be expected

to have a material adverse effect on the business, properties, assets, liabilities, operations, financial condition, prospects, stockholders’

equity or results of operations of Forge Nano or any of its subsidiaries or materially and adversely affect the validity of the Securities

or the legal authority or ability of Forge Nano to comply in all material respects with the terms of this Subscription Agreement (an

“Forge Nano Material Adverse Effect”); (ii) result in any violation of the provisions of the organizational documents

of Forge Nano or any of its subsidiaries which would, individually or in the aggregate, reasonably be expected to have a Forge Nano Material

Adverse Effect; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any Authority

having jurisdiction over Forge Nano or any of its subsidiaries or any of its properties that would reasonably be expected to have, individually

or in the aggregate, a Forge Nano Material Adverse Effect.

2.3.4        Neither

Forge Nano, nor any person acting on its behalf has, directly or indirectly, made any offers or sales of any Company security or solicited

any offers to buy any security, under circumstances that would adversely affect reliance by the Company on Section 4(a)(2) of

the Securities Act for the exemption from registration for the transactions contemplated hereby or would require registration of the

issuance or sale of the Securities under the Securities Act.

2.3.5        Neither

Forge Nano nor any person acting on its behalf has conducted any general solicitation or general advertising (as those terms are used

in Regulation D under the Securities Act) in connection with the offer or sale of any of the Securities and neither Forge Nano, nor any

person acting on its behalf has offered any of the Securities in a manner involving any public offering under, or in a distribution in

violation of, the Securities Act or any state securities laws.

2.3.6        Forge

Nano has not taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership,

liquidation, administration or winding up or failed to pay its debts when due, nor does Forge Nano have any knowledge or reason to believe

that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or seek to commence an administration.

2.3.7        Assuming

the accuracy of Subscriber’s representations and warranties set forth in this Subscription Agreement, no registration under the

Securities Act is required for the offer and sale of the Securities and the Securities are not being offered in a manner involving a

public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

2.3.8        Other

than the Initial Subscription Agreement and the Other Subscription Agreements, the Transaction Agreement and any other agreement expressly

contemplated by the Transaction Agreement, Forge Nano has not entered into any side letter or similar agreement with any Other Subscriber

or any other investor in connection with such Other Subscriber’s or investor’s investment in Forge Nano (in each case for

investments that will occur on or about the time of the Subscriber’s investment). Other than the Initial Subscription Agreement,

no Other Subscription Agreement includes a price per Security different from this Subscription Agreement or other terms, rights or conditions

that are more advantageous (economically or otherwise) in any material respect to any such Other Subscriber than Subscriber hereunder,

and such Other Subscription Agreements have not been amended or modified in any material respect following the date of this Subscription

Agreement in any manner that materially benefits the Other Subscriber thereunder unless Subscriber has been granted the same benefits.

2.3.9        Forge

Nano is not, and immediately after receipt of payment for the Securities will not be, an “investment company” within the

meaning of the Investment Company Act of 1940, as amended.

2.3.10      As

of the date of this Agreement, Forge Nano has not received any written communication from any Authority that alleges that Forge Nano

is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation

would not, individually or in the aggregate, be reasonably expected to have an Forge Nano Material Adverse Effect.

2.3.11       Except

for such matters as have not had and would not be reasonably expected to have, individually or in the aggregate, a Forge Nano Material

Adverse Effect as of the date of this Subscription Agreement, there is no (i) action, claim, inquiry, arbitration, investigation,

litigation or other proceeding pending, or, to the knowledge of Forge Nano, threatened against Forge Nano or (ii) judgment, decree,

injunction, ruling or order of any Authority outstanding against Forge Nano.

2.3.12      Except

for discussions specifically regarding the offer and sale of the Securities and the Investor Presentation, Forge Nano confirms that neither

it nor any other person acting on its behalf has provided Subscriber or its agents or counsel with any information that constitutes or

could reasonably be expected to constitute material, nonpublic information concerning Forge Nano or any of its subsidiaries, other than

with respect to the Transaction and the transactions contemplated by this Subscription Agreement or the Other Subscription Agreements.

Except with respect to the Transaction and the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements,

no event or circumstance has occurred which, under applicable law, rule or regulation, requires public disclosure at or before the

date hereof or announcement by Forge Nano but which has not been so publicly disclosed.

2.3.13      With

respect to the distribution of information to Subscriber (if a Foreign Purchaser) or any Other Subscriber that are Foreign Purchasers,

Forge Nano has and will comply with the regulations associated with the CFIUS. Without limiting the foregoing, Forge Nano represents,

warrants and agrees that it has not provided and does not intend to provide and will take measure to prevent the provision to any Foreign

Purchasers any (i) access to any material non-public technical information (as defined in 31 C.F.R. §801.208) in the possession

of Forge Nano, or (ii) involvement, other than through the voting of shares, in substantive decision-making of Forge Nano regarding

the use, development, acquisition or release of critical technology (as defined in 31 C.F.R §801.204).

Settlement Date and Delivery.

3.1            Closing.

The closing of the Subscription contemplated hereby (the “Closing”) is contingent upon the substantially concurrent

consummation of the Transaction, as provided for by the Transaction Agreement. The Closing shall occur on the closing date of, and immediately

prior to, or simultaneously with, the consummation of the Transaction. Upon written notice from (or on behalf of) the Company to Subscriber

(the “Notice”) that the Company reasonably expects the closing of the Transaction to take place on a date that is

not less than five (5) business days from the date of the Notice, Subscriber shall deliver to the Company, not less than two (2) business

days prior to the scheduled closing date specified in the Notice (the “Scheduled Closing Date”), to be held in escrow

until the Closing, the Purchase Price for the Securities by wire transfer of United States dollars in immediately available funds to

the account specified by the Company in the Notice, which at the Closing will be released to the Company against delivery by the Company

promptly after the Closing to Subscriber of the Securities in book-entry form (or in certificated form if indicated by Subscriber on

Subscriber’s signature page hereto), free and clear of any liens or other restrictions (other than those arising under this

Subscription Agreement or applicable securities laws). Not later than one (1) business day after the Closing, the Company shall

deliver to Subscriber the Securities in book entry form, in the name of Subscriber (or its nominee in accordance with its delivery instructions)

or to a custodian designated by Subscriber, as applicable. In the event the Closing does not occur within five (5) business days

of the Scheduled Closing Date, the Company shall promptly (but not later than two (2) business days thereafter) return the Purchase

Price to Subscriber by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber, and any book-entries

for the Securities shall be deemed repurchased and cancelled. Unless this Subscription Agreement is terminated pursuant to Section 5

below, the failure of the Closing to occur on or after the Scheduled Closing Date shall not terminate this Subscription Agreement or

otherwise relieve any party of any of its obligations hereunder. For purposes of this Subscription Agreement, “business day”

means any day that, in New York, New York, is neither a legal holiday nor a day on which commercial banking institutions are generally

authorized or required by law or regulation to close (excluding as a result of “stay at home”, “shelter-in-place”,

“non-essential employee” or any other similar orders or restrictions or the closure of any physical branch locations at the

direction of any governmental authority so long as the electronic funds transfer systems, including for wire transfers, of commercial

banking institutions in New York, New York are generally open for use by customers on such day).

3.2            Conditions

to Closing.

3.2.1        The

Closing shall be subject to the satisfaction or valid waiver by the Company and Forge Nano, on the one hand, or Subscriber, on the other,

of the conditions that, on the Closing Date:

(i)             No

Authority shall have enacted, issued, promulgated, enforced or entered any law, rule, regulation, judgment, decree, executive order or

award (whether temporary preliminary or permanent) which is then in effect and has the effect of making the transactions contemplated

hereby illegal or otherwise prohibiting or enjoining the consummation of the transactions contemplated hereby.

(ii)            Transaction

Closing shall be substantially concurrent with the Closing.

3.2.2        The

Closing shall also be subject to the satisfaction or valid waiver by the Subscriber of the conditions that, on the Closing Date:

(i)            The

Company and Forge Nano shall have performed, satisfied and complied in all material respects with all agreements, conditions and covenants

required by this Subscription Agreement to be performed by the Company or Forge Nano at or prior to the Closing.

(ii)            All

representations and warranties of Company and Forge Nano contained in this Subscription Agreement shall be true and correct in all material

respects (other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect or Forge

Nano Material Adverse Effect, as applicable, which representations and warranties shall be true in all respects) at and as of the Closing

Date (except for representations and warranties made as of a specific date, which shall be true and correct in all material respects

(other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect or Forge Nano Material

Adverse Effect, as applicable, which representations and warranties shall be true in all respects) as of such date), and consummation

of the Closing shall constitute a reaffirmation by the Company and Forge Nano of each of the representations, warranties and agreements

of the Company and Forge Nano contained in this Subscription Agreement as of the Closing Date.

(iii)          The

Company shall have filed with Nasdaq an application or for the listing of the Securities and Nasdaq shall have raised no objection with

respect thereto, subject to official notice of issuance.

(iv)          Other

than with respect to the Initial Subscription Agreement, there shall have been no amendment, waiver or modification to the Other Subscription

Agreements that materially benefits (economically or otherwise) the Other Subscribers thereunder unless this Subscription Agreement shall

have been amended to reflect the same terms.

(v)           No

suspension of the qualification of the Securities for offering or sale or trading of the Common Stock on the Nasdaq shall have occurred

and be continuing.

(vi)          No

amendments, modifications or waivers to the terms of the Transaction Agreement (as it exists on the date hereof as provided to Subscriber)

shall have occurred, in each case, in a manner that would reasonably be expected to materially and adversely affect the economic benefits

that Subscriber would reasonably expect to receive under this Subscription Agreement (unless Subscriber has provided its written consent

thereto).

3.2.3        The

Closing shall also be subject to the satisfaction or valid waiver by each of the Company and Forge Nano of the conditions that, on the

Closing Date:

(i)             Subscriber

shall have performed, satisfied and complied in all material respects with all agreements, conditions and covenants required by this

Subscription Agreement to be performed by Subscriber at or prior to the Closing.

(ii)            All

representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects

(other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which representations

and warranties shall be true in all respects) at and as of the Closing Date (except for representations and warranties made as of a specific

date, which shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality

or Subscriber Material Adverse Effect, which representations and warranties shall be true in all respects) as of such date), and consummation

of the Closing shall constitute a reaffirmation by the Subscriber of each of the representations, warranties and agreements of the Subscriber

contained in this Subscription Agreement as of the Closing Date.

4.             Transfer

Restrictions.

4.1           After

the Closing, the Securities may only be resold, transferred, pledged or otherwise disposed of in compliance with state and federal securities

laws and pursuant to an effective registration statement, Rule 144 under the Securities Act (“Rule 144”)

or pursuant to another applicable exemption from the registration requirements of the Securities Act, to the Company or to an affiliate

of Subscriber. As a condition of transfer (other than pursuant to an effective registration statement pursuant to Rule 144 or pursuant

to another applicable exemption from the registration requirements of the Securities Act), any such transferee shall agree in writing

to be bound by the terms of this Subscription Agreement and shall have the rights and obligations of Subscriber under this Agreement.

4.2           Notwithstanding

anything to the contrary, the Company and Forge Nano acknowledge that the Securities may be pledged by Subscriber in connection with

a bona fide margin agreement, which shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and Subscriber

effecting a pledge of the Securities shall not be required to provide the Company or Forge Nano with any notice thereof; provided, however,

that neither the Company nor its counsel shall be required to take any action (or refrain from taking any action) in connection with

any such pledge, other than providing any such lender of such margin agreement with an acknowledgment that the Securities are not subject

to any contractual lock up or prohibition on pledging, the form of such acknowledgment to be reasonably acceptable to the Company in

all respects; provided further that the Subscriber and its pledgee shall be required to comply with other provisions of this Section 4

in order to effect a sale, transfer or assignment of Securities to a pledgee.

4.3           Subject

to applicable requirements of the Securities Act and the interpretations of the Commission thereunder and any requirements of the Company’s

transfer agent, the Company shall use commercially reasonable efforts to ensure that instruments, whether certificated or uncertificated,

evidencing the Securities shall not contain any legend (including the legend set forth in Section 4.4 below) (i) following

any sale of such Securities pursuant to Rule 144, (ii) if such Securities are eligible for sale under Rule 144 without

the requirement for the Company to be in compliance with the current public information required under Rule 144 (including under

Rule 144(i)) and without volume or manner-of-sale restrictions, and in each case, Subscriber provides the Company with an undertaking

to effect any sales or other transfers in accordance with the Securities Act, or (iii) if such legend is not required under applicable

requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

4.4           Subscriber

agrees to the imprinting, so long as is required by this Section 4, of a legend on any of the Securities in the following

form:

THIS SECURITY HAS NOT BEEN

REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION

UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR

SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN

A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES

LAWS.

4.5           [Reserved].

4.6           The

Company will use its commercially reasonable efforts to make all Securities eligible on the Direct Registration System of the Depository

Trust Company so that Subscriber can, subject to Section 4.3, move shares to respective prime broker accounts and sell without restriction.

5.              Termination.

Except for the provisions of Sections 5, 7, 8 and 9 and the provisions of this Agreement providing for the return of funds previously

delivered in the event the Closing does not occur, all of which shall survive any termination hereunder, this Subscription Agreement

shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate

without any further liability on the part of any party in respect thereof, upon the earliest to occur of (i) such date and time

as the Transaction Agreement is terminated in accordance with its terms, (ii) upon the mutual written agreement of each of the parties

hereto to terminate this Subscription Agreement, (iii) at the election of Subscriber, if the Closing shall not have occurred on

or before the Outside Date (as defined in the Transaction Agreement), or (iv) if any of the conditions to Closing set forth in Section 3.2

are not satisfied on or prior to the Closing Date and, as a result thereof, the transactions contemplated by this Subscription Agreement

are not consummated at the Closing; provided, that, subject to the limitations set forth in Section 8, nothing herein will relieve

any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies

at law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination

of the Transaction Agreement promptly after the termination of such agreement. Upon the termination hereof in accordance with this Section 5,

any monies paid by Subscriber to the Company in connection herewith shall promptly (and in any event within two (2) business days)

be returned in full to Subscriber by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber,

without any deduction for or on account of any tax withholding except as required by law, charges or set-off, whether or not the Transactions

shall have been consummated.

6.             Registration

Rights.

6.1           The

Company agrees that within thirty (30) days after the Closing Date, the Company will file with the Commission (at the Company’s

sole cost and expense) a registration statement to register under and in accordance with the provisions of the Securities Act, the resale

of all of the Registrable Securities (as defined below) on Form S-3 or Form S-1 (which in either case shall be filed pursuant

to Rule 415 under the Securities Act as a secondary-only registration statement), which shall be on Form S-3 if the Company

is then eligible for such short form, or any similar or successor short form registration or, if the Company is not then eligible for

such short form registration or would not be able to register for resale all of the Registrable Securities on Form S-3, on Form S-1

or any similar or successor long form registration (the “Registration Statement”). The Company will provide a draft

of the Registration Statement to Subscriber for review at least two (2) business days in advance of the filing the Registration

Statement, and shall advise Subscriber promptly upon the Registration Statement being declared effective by the Commission. The Company

shall use its commercially reasonable efforts to have the Registration Statement declared effective by the Commission as soon as practicable

after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days (or ninety (90) calendar days if the Commission

notifies the Company that it will “review” the Registration Statement) following the Closing Date and (ii) the fifth

(5th) business day after the date the Company is notified in writing by the Commission that the Registration Statement will

not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”);

provided, however, that the Company’s obligations to include the Registrable Securities of Subscriber in the Registration Statement

are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company

held by Subscriber and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company

to effect the registration of the Registrable Securities, and Subscriber shall execute such documents in connection with such registration

as the Company may reasonably request that are customary of a selling shareholder in similar situations. Notwithstanding the foregoing,

if the Commission prevents the Company from including any or all of the Common Stock proposed to be registered under the Registration

Statement due to limitations on the use of Rule 415 under the Securities Act for the resale of the Registrable Securities by the

Subscribers or otherwise, the Company shall use its best efforts to ensure that the Commission determines that the offering contemplated

by the Registration Statement is a bona fide secondary offering and not an offering “by or on behalf of the issuer” as defined

in Rule 415 of the Securities Act. If the Company is unsuccessful in the efforts described in the preceding sentence then the Company

shall cause such Registration Statement to register for resale such number of Registrable Securities which is equal to the maximum number

of Common Stock as is permitted by the Commission. In such event, the number of Registrable Securities to be registered for each selling

shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable

after being permitted to register additional Securities under Rule 415 under the Securities Act, the Company shall amend the Registration

Statement or file a new Registration Statement to register such additional Registrable Securities that were not included in the initial

Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. In no event

shall the Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided,

that if the Commission requests that the Subscriber be identified as a statutory underwriter in the Registration Statement, the Subscriber

will have the option, in its sole and absolute discretion, to either (i) have an opportunity to withdraw from the Registration Statement,

in which case the Company’s obligation to register the Subscriber’s Registrable Securities will be deemed satisfied, or (ii) be

included as such in the Registration Statement. The Company will use its commercially reasonable efforts to maintain the continuous effectiveness

of the Registration Statement until the earliest of (x) such time as when all of Subscriber’s securities included therein

cease to be Registrable Securities, (y) such time as when all of Subscriber’s Registrable Securities (as defined below) included

in such Registration Statement have actually been sold and (z) three years from the Closing Date. The Company will use its commercially

reasonable efforts to cause the removal of all restrictive legends from any Registrable Securities being sold under the Registration

Statement at the time of sale of such Registrable Securities upon the receipt from the Subscriber of such supporting documentation, if

any, as requested by the Company. The Company will use commercially reasonable efforts to file all reports, and provide all customary

and reasonable cooperation, reasonably necessary to enable Subscriber to resell Registrable Securities pursuant to the Registration Statement

and Rule 144, qualify the Registrable Securities for listing on the applicable stock exchange and update or amend the Registration

Statement as necessary to include Registrable Securities. “Registrable Securities” shall mean, as of any date of determination,

the Securities and any other equity security issued or issuable with respect to the Securities by way of share split, dividend, distribution,

recapitalization, merger, exchange, replacement or similar event, provided, however, that such securities shall cease to be Registrable

Securities at the earliest of (A) three (3) years after the Closing Date, (B) the date all Securities held by Subscriber

may be sold by Subscriber without volume or manner of sale limitations pursuant to Rule 144 and without the requirement for the

Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable),

(C) the date on which such securities have actually been sold by Subscriber, or (D) when such securities shall have ceased

to be outstanding. Notwithstanding the foregoing, Subscriber shall not be required to sign any form of lock-up agreement in connection

with the Registration Statement. Subscriber may deliver written notice (an “Opt-Out Notice”) to the Company requesting

that Subscriber not receive notices from the Company otherwise required by this Section 6.1; provided, however, that Subscriber

may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked),

(i) the Company shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated

with any such notice and (ii) Subscriber will notify the Company in writing at least three (3) business days in advance of

each intended use of an effective Registration Statement, and if a notice of a Suspension Event (as defined below) was previously delivered

(or would have been delivered but for the provisions of this Section 6.1) and the related suspension period remains in effect, the

Company will so notify Subscriber, within two (2) business days after Subscriber’s notification to the Company, by delivering

to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the

conclusion of such Suspension Event promptly following its availability.

6.2           At

its expense the Company shall:

6.2.1        except

for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use

its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities

laws that the Company determines to obtain in connection with such registration, continuously effective with respect to Subscriber, and

to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions,

until all Securities acquired by Subscriber hereunder cease to be Registrable Securities or such shorter period upon which Subscriber

has notified the Company that such Registrable Securities have actually been sold, or otherwise when such Registration Statement is no

longer required to be effective under this Section 6;

6.2.2        subject

to an Opt-Out Notice, advise Subscriber within three (3) business days: (A) of the issuance by the Commission of any stop order

suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (B) of the receipt

by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein

for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (C) subject to the provisions

in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement

or prospectus included therein so that, as of such date, the statements therein are not misleading and do not omit to state a material

fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances

under which they were made) not misleading. Notwithstanding anything to the contrary set forth herein, the Company shall not, when so

advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Company other than to the

extent that providing notice to Subscriber of the occurrence of the events listed in (A) through (C) above constitutes material,

nonpublic information regarding the Company;

6.2.3        use

its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement

as promptly as reasonably practicable;

6.2.4        upon

the occurrence of any event contemplated in Section 6.2.2, except for such times as the Company is permitted hereunder to suspend,

and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable

efforts to as promptly as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to

the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities

included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary

to make the statements therein, in the light of the circumstances under which they were made, not misleading;

6.2.5        use

its commercially reasonable efforts to cause all Securities to be listed on each securities exchange or market, if any, on which the

Common Stock issued by the Company have been listed; and

6.2.6        use

its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated

hereby.

6.3           Notwithstanding

anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness of the

Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness

thereof, (i) if any information (e.g., compensation data) is not readily available and the non-disclosure of which in the Registration

Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of external legal

counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, (ii) at any time the Company

is required to file a post-effective amendment to the Registration Statement and the Commission has not declared such amendment effective

or (iii) if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred,

which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of external legal

counsel, would require additional disclosure by the Company in the Registration Statement of material non-public information that the

Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would

be expected, in the reasonable determination of the Company’s board of directors, upon the advice of external legal counsel, to

cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension

Event”); provided, however, the Company shall not so delay filing or so suspend the use of the Registration Statement on more

than two (2) occasions or for a period of more than sixty (60) consecutive days or more than a total of ninety (90) calendar days,

in each case in any three hundred sixty (360) day period. Upon receipt of any written notice from the Company of the happening of any

Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration

Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated

therein or necessary to make the statements therein, in the light of the circumstances under which they were made (in the case of the

prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Registrable Securities

under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Subscriber

receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare after the completion of the Suspension

Event) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment

has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain

the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena.

If so directed by the Company, Subscriber will deliver to the Company or, in such Subscriber’s sole discretion destroy, all copies

of the prospectus covering the Registrable Securities in such Subscriber’s possession; provided, however, that this obligation

to deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (i) to the extent such Subscriber

is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional

requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically

on archival servers as a result of automatic data back-up.

6.4           The

Company shall indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), and any of its

officers, directors, agents, partners, members, stockholders, affiliates, managers, investment advisers and employees, and each person

who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the

officers, directors, members, managers, partners, agents and employees of each such controlling person, to the fullest extent permitted

by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including reasonable out-of-pocket external

attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) and expenses (collectively,

“Losses”), as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact

contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment

or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a

material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus

or supplement thereto, in the light of the circumstances under which they were made) not misleading, except insofar as and to the extent,

but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information

regarding Subscriber furnished in writing to the Company by such Subscriber expressly for use therein in connection with the registration

of the Common Stock; provided, however, that the indemnification contained in this Section 6 shall not apply to amounts paid in

settlement of any Losses if such settlement is effected without the consent of the Company, nor shall the Company be liable for any Losses

to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information

furnished by such Subscriber, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus

made available by the Company in a timely manner, (C) as a result of offers or sales effected by or on behalf of any person by means

of a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that was not authorized in writing

by the Company, or (D) in connection with any offers or sales effected by or on behalf of such Subscriber in violation of Section 6.3

hereof. Subscriber shall notify the Company promptly of the institution of any proceeding arising from or in connection with the transactions

contemplated by this Section 6 of which Subscriber becomes aware, provided that a failure by Subscriber to provide such notice shall

not impact Subscriber’s right to be indemnified hereunder unless the Company is actually prejudiced thereby. Such indemnity shall

remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer

of the Securities by Subscriber.

6.5           Subscriber

shall (severally and not jointly with any Other Subscriber) indemnify and hold harmless the Company, its directors, officers, agents

and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20

of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or

are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included

in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus,

or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make

the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances

under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based

solely upon information regarding Subscriber furnished in writing to the Company by Subscriber expressly for use therein; provided, however,

that the indemnification contained in this Section 6 shall not apply to amounts paid in settlement of any Losses if such settlement

is effected without the consent of Subscriber. In no event shall the liability of Subscriber be greater in amount than the dollar amount

of the net proceeds received by Subscriber upon the sale of the Registrable Securities giving rise to such indemnification obligation.

The Company shall notify Subscriber promptly of the institution of any proceeding arising from or in connection with the transactions

contemplated by this Section 6 of which the Company becomes aware, provided that a failure by the Company to provide such notice

shall not impact the Company’s right to be indemnified hereunder unless Subscriber is actually prejudiced thereby. Such indemnity

shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive

the transfer of the Securities by Subscriber.

6.6           If

the indemnification provided under this Section 6 from the indemnifying party is unavailable or insufficient to hold harmless an

indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party,

in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of

such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying

party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party

and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or

alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information

supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative

intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as

a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in this

Section 6, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or

proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall

be entitled to contribution pursuant to this Section 6 from any person who was not guilty of such fraudulent misrepresentation.

Each indemnifying party’s obligation to make a contribution pursuant to this Section 6.6 shall be individual, not joint and

several, and in no event shall the liability of Subscriber hereunder be greater in amount than the dollar amount of the net proceeds

received by Subscriber upon the sale of the Registrable Securities giving rise to such indemnification obligation.

7.             Miscellaneous.

7.1           Further

Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions

as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription

Agreement.

7.1.3        The

Company may request from Subscriber such additional information as the Company may deem reasonably necessary to evaluate the eligibility

of Subscriber to acquire the Securities, and Subscriber shall use reasonable best efforts to promptly provide such information as may

that the Company agrees to keep confidential any such information provided by Subscriber.

7.3           Entire

Agreement. This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings,

representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof (other than any confidentiality

agreement entered into by the Company and Subscriber in connection with the Offering).

7.4           Modifications

and Amendments. This Subscription Agreement may not be modified, waived or terminated except by an instrument in writing, signed

by the parties hereto.

7.5           Waivers

and Consents. The terms and provisions of this Subscription Agreement may be waived, or consent for the departure therefrom granted,

only by a written document executed by the party against whom enforcement of such waiver or consent is sought. No such waiver or consent

shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this Subscription Agreement,

whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it

was given, and shall not constitute a continuing waiver or consent. No failure or delay by a party hereto in exercising any right, power

or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such

right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by

a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party

from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy

by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand

on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other

or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or

demand to any other or further action in any circumstances without such notice or demand.

7.6           Assignment.

Neither this Subscription Agreement nor any rights, interests or obligations that may accrue to the Subscriber hereunder (other than

the Securities acquired hereunder by Subscriber, if any, after the Closing) may be transferred or assigned without the prior written

consent of the Company, and any purported transfer or assignment without such consent shall be null and void ab initio; provided,

however, Subscriber may transfer or assign its rights, interests and obligations hereunder to a controlled affiliate of Subscriber

or another investment fund or account managed or advised by the same manager as Subscriber (or a related party or affiliate) that can

satisfy the requirements of Section 2.1.4 and the other representations and warranties in Section 2.1; provided, further,

that no such transfer or assignment without the prior express written consent of the Company shall release Subscriber of its obligations

hereunder and such transferee(s) or assignee(s), as applicable, agrees in writing to be bound by the terms hereof as if it were

the original Subscriber party hereto.

7.7           Benefit.

Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto

and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations,

warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors,

administrators, successors, legal representatives and permitted assigns. Except as expressly provided for herein, this Subscription Agreement

shall not confer rights or remedies upon any person other than the parties hereto and their respective successors and permitted assigns.

7.8           Governing

Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription

Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement

of this Subscription Agreement, shall be governed by and construed in accordance with the laws of the State of New York, without giving

effect to the principles of conflicts of law thereof.

7.9           Consent

to Jurisdiction; Waiver of Jury Trial. The parties hereto agree to submit any matter or dispute resulting from or arising out of

the execution, performance, interpretation, breach or termination of this Agreement to the exclusive jurisdiction of federal or state

courts within the County of New York, State of New York (and any appellate courts thereof) (the “Specified Courts”).

Each of the parties agrees that service of any process, summons, notice or document in the manner set forth in Section 7.2 hereof

or in such other manner as may be permitted by applicable law, shall be effective service of process for any proceeding with respect

to any matters to which it has submitted to jurisdiction in this Section 7.9. Each of the parties hereto irrevocably and unconditionally

agrees that it is subject to, and hereby submits to, the personal jurisdiction of the Specified Courts for any action, suit or proceeding

arising out of this Subscription Agreement or the transactions contemplated hereunder and waives any objection to the laying of venue

in the Specified Courts (the United States District Court for the Southern District of New York, or the applicable New York state courts

if the federal jurisdictional standards are not satisfied), and hereby further irrevocably and unconditionally waives and agrees not

to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient

forum. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ITS RIGHTS TO A TRIAL BY JURY.

7.10         Non-Reliance

and Exculpation. Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty

made by any person other than the statements, representations and warranties of the Company expressly contained in Section 2.2 of

this Subscription Agreement, in making its investment or decision to invest in the Company. Subscriber further acknowledges and agrees

that no Other Subscriber pursuant to Other Subscription Agreements (including the controlling persons, members, officers, directors,

partners, agents, employees or other representatives of any such Other Subscriber) shall be liable to Subscriber pursuant to this Subscription

Agreement for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Securities.

7.11         Severability.

If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability

of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in

full force and effect. Upon such determination that any provision is invalid, illegal or unenforceable, the parties will substitute for

any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out so far as may be valid, legal and

enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

7.12         Survival

of Representations and Warranties. All representations and warranties made by the parties hereto in this Subscription Agreement or

in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the Closing until the expiration

of any statute of limitations under applicable law.

7.13         Expenses.

Each of the parties hereto shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated

herein.

7.14         Headings

and Captions. The headings and captions of the various subdivisions of this Subscription Agreement are for convenience of reference

only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.

7.15         Counterparts.

This Subscription Agreement may be executed in one or more counterparts (including by facsimile or electronic mail or in .pdf), all of

which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed

by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event

that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid

and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such

signature page were an original thereof.

7.16         Construction.

The words “include,” “includes,” and “including” will be deemed to be followed

by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other

gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires.

The words “this Subscription Agreement,” “herein,” “hereof,” “hereby,”

“hereunder,” and words of similar import refer to this Subscription Agreement as a whole and not to any particular

subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein

will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any

respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the

relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto

is in breach of the first representation, warranty, or covenant. All references in this Subscription Agreement to numbers of shares,

per share amounts and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock combination,

recapitalization or the like occurring after the date hereof. As used in this Subscription Agreement, the term: (x) “person”

shall refer to any individual or corporation, partnership, trust, incorporated or unincorporated association, joint venture, limited

liability company, joint stock company, government (or an agency or subdivision thereof) or other entity of any kind; and (y) “affiliate”

shall mean, with respect to any specified person, any other person or group of persons acting together that, directly or indirectly,

through one or more intermediaries controls, is controlled by or is under common control with such specified person (where the term “control”

(and any correlative terms) means the possession, direct or indirect, of the power to direct or cause the direction of the management

and policies of such person, whether through the ownership of voting securities, by contract or otherwise).

7.17         Mutual

Drafting. This Subscription Agreement is the joint product of Subscriber, the Company and Forge Nano and each provision hereof has

been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party

hereto.

7.18         Remedies.

7.18.1      The

parties agree that irreparable damage would occur if this Subscription Agreement was not performed in accordance with its specific terms

or was otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly

agreed that the parties hereto shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent

breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription

Agreement in an appropriate court of competent jurisdiction as set forth in Section 7.9, this being in addition to any other remedy

to which any party is entitled at law or in equity, including money damages. The right to specific enforcement shall include the right

of the parties hereto to cause to cause the other parties hereto to cause the transactions contemplated hereby to be consummated on the

terms and subject to the conditions and limitations set forth in this Subscription Agreement. The parties hereto further agree (i) to

waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that

a remedy of specific enforcement pursuant to this Section 7.18 is unenforceable, invalid, contrary to applicable law or inequitable

for any reason and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law

would be adequate.

7.18.2      The

parties acknowledge and agree that this Section 7.18 is an integral part of the transactions contemplated hereby and without that

right, the parties hereto would not have entered into this Subscription Agreement.

8.             Disclosure.

8.1           The

SPAC shall, by 5:30 p.m., New York City time, on the first (1st ) business day immediately following the date of this Subscription

Agreement file a Current Report on Form 8-K with the Commission (the time of such filing, “Disclosure Time”)

disclosing and describing all material terms of the transactions contemplated hereby and the Transaction Agreement, and a form of this

Subscription Agreement will be filed with the Commission as an exhibit thereto. From and after the Disclosure Time, the Company represents

to Subscriber that it shall have publicly disclosed all material, non-public information delivered to Subscriber by the Company, Forge

Nano or any of their officers, directors, employees or agents in connection with the transactions contemplated by the Subscription Agreement

and the Transaction Agreement, and Subscriber shall no longer be subject to any confidentiality or similar obligations under any current

agreement, whether written or oral with Company or any of their affiliates, relating to the transactions contemplated by this Subscription

Agreement and the Transaction Agreement.

8.2           Notwithstanding

anything in this Subscription Agreement to the contrary, none of the SPAC, the Company or Forge Nano shall publicly disclose the name

of Subscriber or any of its affiliates, or include the name of Subscriber or any of its affiliates in any press release or in any filing

with the Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except (i) as required

by the federal securities law in connection with the Registration Statement, and (ii) to the extent such disclosure is required

by law, at the request of the Staff of the Commission or regulatory agency or under the regulations of Nasdaq, in which case under clause

(i) or (ii) above, the Company shall provide Subscriber with prior written notice of such disclosure, and shall reasonably

consult with the Subscriber regarding such disclosure.

9.             Trust

Account Waiver. Subscriber acknowledges that the SPAC is a blank check company with the powers and privileges to effect a merger,

asset acquisition, reorganization or similar business combination involving the SPAC and one or more businesses or assets. Subscriber

further acknowledges that, as described in the Prospectus available at www.sec.gov, substantially all of the SPAC’s assets consist

of the cash proceeds of SPAC’s initial public offering (including overallotment securities sold by the SPAC’s underwriter

thereafter) and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account

(the “Trust Account”) for the benefit of SPAC, its public shareholders and the underwriters of SPAC’s initial

public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to SPAC to pay its

tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in

consideration of the SPAC entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber,

on behalf of itself and its representatives, hereby irrevocably waives any and all right, title and interest, or any claim of any kind

they now have or may have in the future, in or to any monies held in the Trust Account or distributions therefrom to the SPAC’s

public stockholders, and agrees not to seek recourse against the Trust Account for any claims in connection with, as a result of, or

arising out of, this Subscription Agreement or the transactions contemplated hereby; provided, however, that nothing in

this Section 9 (x) shall serve to limit or prohibit Subscriber’s right to pursue a claim against SPAC for legal

relief against assets held outside the Trust Account (other than distributions to the SPAC’s public stockholders), for specific

performance or other equitable relief, (y) shall serve to limit or prohibit any claims that Subscriber may have in the future against

SPAC’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account

(other than distributions to the SPAC’s public stockholders) and any assets that have been purchased or acquired with any such

funds) or (z) shall be deemed to limit any Subscriber’s right, title, interest or claim to the Trust Account by virtue of

such Subscriber’s record or beneficial ownership of securities of the SPAC acquired by any means other than pursuant to this Subscription

Agreement, including but not limited to any redemption right with respect to any such securities of the SPAC.

10.           Reliance.

10.1         Subscriber

acknowledges that the Company and BTIG, LLC (the “Placement Agent”) will rely on the acknowledgements, understandings,

agreements, representations and warranties of Subscriber contained in this Subscription Agreement. Subscriber agrees to promptly notify

the Company and BTIG, LLC if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties

of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that the purchase

by Subscriber of Securities from the Company will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations

and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase. The Company acknowledges that Subscriber

and BTIG, LLC will rely on the acknowledgments, understandings, agreements, representations and warranties of the Company contained in

this Subscription Agreement.

10.2         Each

of the Company and BTIG, LLC and Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any

interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby to the extent

required by law or regulatory bodies.

Subscriber agrees that BTIG,

LLC shall not be liable to it (including in contract, tort, under federal or state securities laws or otherwise) for any action heretofore

or hereafter taken or omitted to be taken by any of them in good faith in connection with the transactions contemplated herein and the

purchase and sale of the Securities hereunder. On behalf of Subscriber and its affiliates, Subscriber releases BTIG, LLC in respect of

any Losses related to the transactions contemplated herein and the purchase and sale of Securities hereunder. Subscriber agrees not to

commence any litigation or bring any claim against BTIG, LLC in any court or other forum which relates to, may arise out of, or is in

connection with, the transactions contemplated herein and the purchase and sale of the Securities hereunder absent BTIG’s gross

negligence and willful misconduct. The undertaking is given freely and after obtaining independent legal advice. Subscriber acknowledges

that BTIG, LLC will receive a fee from SPAC with respect to the sale of Securities and a deferred underwriting commission in connection
