**ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION**

**ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS**

Nevada law provides that a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation (i.e., a "non-derivative proceeding"), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he or she:

● Is not liable under Section 78.138 of the Nevada Revised Statutes for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

In addition, a Nevada corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor (i.e., a "derivative proceeding"), by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys' fees actually and reasonably incurred by him or her in connection with the defense or settlement of the action or suit if he:

● Is not liable under Section 78.138 of the Nevada Revised Statute for breach of his or her fiduciary duties to the corporation; or

● Acted in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation.

Under Nevada law, indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any non-derivative proceeding or any derivative proceeding, or in defense of any claim, issue or matter therein, the corporation is obligated to indemnify him or her against expenses, including attorneys' fees, actually and reasonably incurred in connection with the defense.

Further, Nevada law permits a Nevada corporation to purchase and maintain insurance or to make other financial arrangements on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise for any liability asserted against him or her and liability and expenses incurred by him or her in his or her capacity as a director, officer, employee or agent, or arising out of his or her status as such, whether or not the corporation has the authority to indemnify him or her against such liability and expenses.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

**ITEM 16. EXHIBITS**

A list of exhibits included as part of this registration statement is set forth in the Exhibit Index and is incorporated herein by reference.

**ITEM 17. UNDERTAKINGS**

(a) The
 undersigned Registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To
 file, during any period in which offers or sales are being made; a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) to
 include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) to
 reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent
 post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set
 forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if
 the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end
 of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if,
 in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set
 forth in the "Calculation of Filing Fee Tables" table in the effective registration statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) to
 include any material information with respect to the plan of distribution not previously disclosed in the registration statement
 or any material change to such information in the registration statement;

*provided, however,* that subparagraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That,
 for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a
 new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be
 deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To
 remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the
 termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) That,
 for the purpose of determining liability under the Securities Act to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Each
 prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the
 date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Each
 prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on
 Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information
 required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the
 earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities
 in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is
 at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities
 in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed
 to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus
 that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration
 statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior
 to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part
 of the registration statement or made in any such document immediately prior to such effective date; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) That,
 for the purpose of determining liability of the Registrant under the Securities Act to any purchaser in the initial distribution
 of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant
 to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities
 are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller
 to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Any
 preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule
 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Any
 free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by
 the undersigned Registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The
 portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant
 or its securities provided by or on behalf of the undersigned Registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any
 other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b) The
 undersigned Registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act, each filing
 of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
 filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
 in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and
 the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar
 as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons
 of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
 SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event
 that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid
 by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted
 by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in
 the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
 question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the
 final adjudication of such issue.

**SIGNATURES**

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on FormS-3 and has duly caused this Pre-Effective Amendment No. 1 to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Hauppauge, State of New York, on July 31, 2025.

Re: AmpliTech Group, Inc. <br> Registration Statement on Form S-3 (File No. 333-288863)

Ladies and Gentlemen:

We act as counsel to AmpliTech Group, Inc., a Nevada corporation (the "<u>Company</u>"), in connection with the filing of a Registration Statement on Form S-3 (File No. 333-288863) filed with the Securities and Exchange Commission (the "<u>Commission</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), on July 22, 2025, and as amended by Pre-Effective Amendment No. 1 to Form S-3 being filed with the Commission on the date hereof (as amended, the "<u>Registration Statement</u>"), relating to the proposed public offerings by the Company from time to time of up to a maximum of $200,000,000 aggregate initial offering price of a presently indeterminate amount of the following securities of the Company (each a <u>"Security</u>" and collectively, or in any combination, the "<u>Securities</u>"):

● shares of common stock, par value $0.001 per share (" <u>Common Stock</u> ");

● one or more classes or series of shares of preferred stock, par value $0.001 per share (" <u>Preferred Stock</u> ");

You have requested our opinion as to the matters set forth below in connection with the Registration Statement. For purposes of rendering the opinion set forth below, we have examined such documents and reviewed such questions of law as we have considered necessary and appropriate for the purposes of our opinion, including (i) the Registration Statement, including the exhibits filed therewith, (ii) the Prospectus, (iii) the Company's amended and restated articles of incorporation as currently in effect (the "<u>Articles of Incorporation</u>"), (iv) the Company's amended and restated bylaws as currently in effect (the "<u>Bylaws</u>"), (v) the corporate minutes and other actions of the Company, and (vi) the originals or copies certified to our satisfaction of such other documents, records, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below.

In addition, in rendering this opinion, we have assumed: (A) the genuineness and authenticity of all signatures on original documents; (B) the genuineness and authenticity of all documents submitted to us as originals; (C) the conformity to originals of all documents submitted to us as copies; (D) the accuracy, completeness and authenticity of certificates of public officials; and (E) the due authorization, execution and delivery of all documents where due authorization, execution and delivery are prerequisites to the effectiveness of such documents (other than with respect to the Company). We have not sought independently to verify such matters.

We express no opinions other than as specifically set forth herein. We are opining solely on all applicable statutory provisions of the Nevada Revised Statutes (the "<u>NRS</u>") and express no opinion as to whether the laws of any other jurisdiction are applicable to the subject matter hereof. We are not rendering any opinion as to compliance with any federal or state law, rule or regulation relating to securities, or to the sale or issuance thereof. This opinion letter deals only with the specified legal issues expressly addressed herein, and you should not infer any opinion that is not explicitly stated herein from any matter addressed in this opinion letter.

Based on the foregoing and in reliance thereon, and subject to the assumptions, qualifications, limitations and exceptions set forth below, we are of the opinion that:
