  <P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Momentus is a U.S. commercial space company that
  plans to offer in-space infrastructure services, including in-space transportation, hosted payloads and in-orbit services. Momentus believes
  it can make new ways of operating in space possible with its planned in-space transfer and service vehicles that will be powered by an
  innovative water plasma-based propulsion system that is under development. The Company anticipates flying its first two Vigoride vehicles
  to Low Earth Orbit on a third-party launch provider no earlier than June 2022, subject to receipt of appropriate government licenses,
  approvals and availability of slots on its launch provider's manifest, for which there is no assurance such licenses, approvals and availability
  will be received, if at all.</P>
  
  <P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>
  
  <P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The technology underlying our anticipated service
  offerings is still in the process of being developed, and has not been fully tested or validated in space. Our ability to execute on our
  business plan is dependent on the successful development and commercialization of the technologies described in this prospectus and any
  accompanying prospectus supplement. Although we believe our water plasma propulsion technology will be a key differentiator of our product
  offerings, we have to date only conducted one test of this technology in space. Although we believe our test unit generated plasma in
  space and validated the theoretical basis of our technology, we have yet to experimentally confirm the unit&rsquo;s ability to generate
  thrust in space, which is crucial to our ability to conduct actual spacecraft maneuvers on orbit. Until we can accomplish this, the technology
  will remain in the experimental stages. Moreover, even if the unit generates thrust, there can be no assurance that it can be operated
  in a manner that is sufficiently reliable and efficient to permit full commercialization of the technology. Our statements and beliefs
  about the viability of our technology are primarily based on theoretical analyses and experimentally observed results during ground testing
  and our single test of this technology in space. Development of space technologies is extremely complex, time consuming, and expensive,
  and there can be no assurance that our predicted theoretical and ground-based results will translate into operational space vehicles that
  operate within the parameters we expect, or at all. This prospectus and any accompanying prospectus supplement describe Momentus&rsquo;
  current business plans for continuing to develop its technology and marketing and commercializing its products, however there can be no
  assurance that Momentus will be able to successfully develop its technologies and implement them in commercially viable vehicles.</P>

  Securityholder in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale

  The forward-looking statements contained in this
  prospectus are based on our current expectations and beliefs concerning future developments and their potential effects on our business.
  There can be no assurance that future developments affecting our business will be those that we have anticipated. These forward-looking

  results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and
  uncertainties include, but are not limited to, those factors described in the section entitled "
  Risk Factors
  ." Moreover,
  we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not
  possible for us to predict all such risk factors, nor can we assess the effect of all such risk factors on our business or the extent
  to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking
  statements. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results
  may vary in material respects from those projected in these forward-looking statements.
  The forward-looking statements made by us in this
  prospectus and any accompanying prospectus supplement speak only as of the date of this prospectus and the accompanying prospectus supplement.

  of unanticipated events. In light of these risks and uncertainties, there is no assurance that the events or results suggested by the
  forward-looking statements will in fact occur, and you are cautioned not to place undue reliance on these forward-looking statements.

  PROSPECTUS SUMMARY
  This summary highlights selected information from this prospectus
  and does not contain all of the information that is important to you in making an investment decision. This summary is qualified in its
  entirety by the more detailed information included in this prospectus, including the documents incorporated by reference herein. Potential
  investors should read the entire prospectus carefully, including the risks of purchasing our common stock discussed in "Risk Factors."
  The Company
  Momentus is a U.S. commercial space company that
  plans to offer in-space infrastructure services, including in-space transportation, hosted payloads and in-orbit services. Momentus believes
  it can make new ways of operating in space possible with its planned in-space transfer and service vehicles that will be powered by an
  innovative water plasma-based propulsion system that is under development. The Company anticipates flying its first two Vigoride vehicles
  to Low Earth Orbit on a third-party launch provider no earlier than June 2022, subject to receipt of appropriate government licenses,
  approvals and availability of slots on its launch provider's manifest, for which there is no assurance such licenses, approvals and availability
  will be received, if at all.
  The technology underlying our anticipated service
  offerings is still in the process of being developed, and has not been fully tested or validated in space. Our ability to execute on our
  business plan is dependent on the successful development and commercialization of the technologies described in this prospectus and any
  accompanying prospectus supplement. Although we believe our water plasma propulsion technology will be a key differentiator of our product
  offerings, we have to date only conducted one test of this technology in space. Although we believe our test unit generated plasma in
  space and validated the theoretical basis of our technology, we have yet to experimentally confirm the unit's ability to generate
  thrust in space, which is crucial to our ability to conduct actual spacecraft maneuvers on orbit. Until we can accomplish this, the technology
  will remain in the experimental stages. Moreover, even if the unit generates thrust, there can be no assurance that it can be operated
  in a manner that is sufficiently reliable and efficient to permit full commercialization of the technology. Our statements and beliefs
  about the viability of our technology are primarily based on theoretical analyses and experimentally observed results during ground testing
  and our single test of this technology in space. Development of space technologies is extremely complex, time consuming, and expensive,
  and there can be no assurance that our predicted theoretical and ground-based results will translate into operational space vehicles that
  operate within the parameters we expect, or at all. This prospectus and any accompanying prospectus supplement describe Momentus'
  current business plans for continuing to develop its technology and marketing and commercializing its products, however there can be no
  assurance that Momentus will be able to successfully develop its technologies and implement them in commercially viable vehicles.
  Background
  We were incorporated in the State of Delaware
  in May 2019 as a special purpose acquisition company under the name Stable Road Acquisition Corp. On November 13, 2019, we completed our
  initial public offering. On August 12, 2021, we consummated the Business Combination with Legacy Momentus pursuant to the Merger
  Agreement. In connection with the Business Combination, we changed our name from Stable Road Acquisition Corp. to Momentus Inc.
  Emerging Growth Company
  As a company with less than $1.07 billion
  in revenues during our last completed fiscal year, we qualify as an "emerging growth company" as defined in the Jumpstart
  Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting requirements
  that are otherwise applicable generally to public companies. These reduced reporting requirements include:
  ●
  an exemption from compliance with the auditor attestation
  requirement on the effectiveness of our internal control over financial reporting;
  ●
  an exemption from compliance with any requirement that the
  Public Company Accounting Oversight Board may adopt regarding a supplement to the auditor's report providing additional information
  about the audit and the financial statements;
  3
  ●
  reduced disclosure about our executive compensation arrangements;
  and
  ●
  an exemption from the requirements to obtain a non-binding advisory
  vote on executive compensation or a stockholder approval of any golden parachute arrangements.
  We may choose to take advantage of some, but not
  all, of the available benefits under the JOBS Act. Accordingly, the information contained herein may be different from the information
  you receive from other public companies in which you hold stock. Further, pursuant to Section 107 of the JOBS Act, as an emerging
  growth company, we have elected to use the extended transition period for complying with new or revised accounting standards until those
  standards would otherwise apply to private companies. As a result, our consolidated financial statements may not be comparable to the
  financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable
  to public companies, which may make our Class A common stock less attractive to investors.
  We will remain an emerging growth company until
  the earlier of (1) the last day of the fiscal year (a) following November 13, 2024, (b) in which we have total annual gross revenue of
  at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Class A common
  stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than
  $1.0 billion in non-convertible debt securities during the prior three-year period.
  About This Offering
  This reoffer prospectus relates to the public offering, which is not
  being underwritten, by the Selling Securityholders listed in this prospectus, of up to 250,712 shares of our Class A common stock, that
  will be issued to each Selling Securityholder under an option agreement between the Company and the Selling Securityholder.
  The Selling Securityholders may from time to time sell, transfer or
  otherwise dispose of any or all of the shares of Class A common stock covered by this prospectus through underwriters or dealers, directly
  to purchasers (or a single purchaser) or through broker-dealers or agents. We will receive none of the proceeds from the sale of the shares
  by the Selling Securityholders. We will bear all expenses of registration incurred in connection with this offering, but all selling and
  other expenses incurred by the Selling Securityholders will be borne by them.
  Risk Factors
  Our business is subject to numerous risks and uncertainties, including
  those highlighted in the section titled "
  Risk Factors
  ", that represent challenges that we face in connection with the
  successful implementation of our strategy and growth of our business.

  RISK FACTORS
  An investment in our securities involves a high degree of risk. You
  should carefully consider the risks described under "Risk Factors" in our Form S-1, filed with the Commission on September
  3, 2021 (which is incorporated by reference herein), as well as the other information contained or incorporated by reference in this
  prospectus or in any prospectus supplement hereto before making a decision to invest in our Class A common stock. Our business, prospects,
  financial condition, or operating results could be harmed by any of these risks, as well as other risks not currently known to us or that
  we currently consider immaterial. The trading price of our securities could decline due to any of these risks, and, as a result, you may
  lose all or part of your investment.
  DETERMINATION OF OFFERING PRICE
  The Selling Securityholders will determine at what price they may sell
  the offered shares, and such sales may be made at prevailing market prices or at privately negotiated prices. See "
  Plan of Distribution
  "
  below for more information.
  USE OF PROCEEDS
  The shares of Class A common stock offered hereby are being registered
  for the account of the Selling Securityholders named in this prospectus. All proceeds from the sales of the Class A common stock will
  go to the Selling Securityholders and we will not receive any proceeds from the resale of the Class A common stock by the Selling Securityholders.
  SELLING SECURITYHOLDERS
  The following table sets forth information
  with respect to the Selling Securityholders and the shares of our Class A common stock beneficially owned by the Selling
  Securityholders as of October 1, 2021 and the percentage of beneficial ownership is calculated based on 73,854,681 shares of Class A
  common stock outstanding as of such date. The Selling Securityholders may offer all, some or none of the shares of Class A common
  stock covered by this prospectus. The Selling Securityholders identified below may have sold, transferred or otherwise disposed of
  some or all of their shares since the date on which the information in the following table is presented in transactions exempt from
  or not subject to the registration requirements of the Securities Act. Further, we cannot give an estimate as to the number of
  shares of Class A common stock that will actually be held by the Selling Securityholders upon termination of this offering because
  the Selling Securityholders may offer some or all of their Class A common stock under the offering contemplated by this prospectus
  or acquire additional shares of Class A common stock, and we cannot advise you as to whether the Selling Securityholders will, in
  fact, sell any or all of such shares of Class A common stock. Any prospectus supplement may add, update, substitute, or change the information contained in this prospectus, including the identity
  of each selling securityholder and the number of shares of Class A common stock registered on their behalf. Selling securityholder information
  for each additional selling securityholder, if any, will be set forth by prospectus supplement to the extent required prior to the time
  of any offer or sale of such selling securityholder's securities pursuant to this prospectus.
  We have determined beneficial ownership in accordance with the rules
  of the SEC and the information is not necessarily indicative of beneficial ownership for any other purpose. Unless otherwise indicated
  below, the address of each Selling Securityholder listed in the table below is c/o Momentus Inc., 3901 N. First Street, San Jose, CA 95134
  and to our knowledge, the persons and entities named in the tables have sole voting and sole investment power with respect to all securities
  that they beneficially own, subject to community property laws where applicable.

  Listing of Common Stock
  Our Class A common stock is currently listed on Nasdaq under the symbol
  "MNTS."
  Other Material Relationships with the Selling Securityholders
  Employment Relationships
  The information set forth in the section titled "Executive Compensation"
  of the Form S-1 filed with the Commission on September 3, 2021 pertaining to Dawn Harms amended and restated offer letter and the Company's
  director compensation policies is incorporated herein by reference.
  Indemnification Agreement and Directors' and Officers'
  Liability Insurance
  The Company has entered into separate indemnification
  agreements with the Company's directors and officers. These agreements, among other things, will require the Company to indemnify
  our directors and officers for certain expenses, including attorneys' fees, judgments, fines and settlement amounts incurred by
  a director or officer in any action or proceeding arising out of their services as one of our directors or officers or any other company
  or enterprise to which the person provides services at our request. Insofar as indemnification for liabilities arising under the Securities
  Act may be permitted to directors, officers, or control persons, in the opinion of the SEC, such indemnification is against public policy
  as expressed in the Securities Act and is therefore unenforceable.
  We also maintain a directors' and officers'
  insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors
  and officers. We believe that the provisions in our second amended and restated charter, our amended and restated bylaws, the directors'
  and officers' liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers
  and directors.
  Lock-Up Agreements
  Certain Selling Securityholders of Legacy Momentus have entered into
  agreements (the "Lock-Up Agreements") pursuant to which they have agreed, subject to certain customary exceptions, not to
  (a) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree
  to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position
  within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder, any Lock-Up Shares,
  (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
  of any of such Lock-Up Shares, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise or (c)
  publicly announce any intention to effect any transaction specified in clause (a) or (b) for 180 days after the Closing (or, if earlier,
  the date that the Class A Common Stock trades at or above $12.00 per share for any 20 trading days in a 30 trading day period after the
  Closing).
  6
  PLAN OF DISTRIBUTION
  The Selling Securityholders may offer and sell,
  from time to time, their respective shares of Class A Stock covered by this prospectus. The Selling Securityholders will act independently
  of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or
  in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market
  price or in negotiated transactions. The Selling Securityholders may sell their securities by one or more of, or a combination of, the
  following methods:
  ●
  purchases by a broker-dealer as principal and resale by such broker-dealer
  for its own account pursuant to this prospectus;
  ●
  ordinary brokerage transactions and transactions in which the
  broker solicits purchasers;
  ●
  block trades in which the broker-dealer so engaged will attempt
  to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
  ●
  an over-the-counter distribution in accordance with the rules
  of Nasdaq;
  ●
  through trading plans entered into by a Selling Securityholder
  pursuant to Rule 10b5-1 under the Exchange Act that are in place at the time of an offering pursuant to this prospectus and any applicable
  prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading
  plans;
  ●
  short sales;
  ●
  distribution to employees, members, limited partners or stockholders
  of the Selling Securityholders;
  ●
  through the writing or settlement of options or other hedging
  transaction, whether through an options exchange or otherwise;
  ●
  by pledge to secured debts and other obligations;
  ●
  delayed delivery arrangements;
  ●
  to or through underwriters or agents;
  ●
  in "at the market" offerings, as defined in Rule 415
  under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market
  prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange
  or other similar offerings through sales agents;
  ●
  in privately negotiated transactions;
  ●
  in options transactions; and
  ●
  through a combination of any of the above methods of sale, as
  described below, or any other method permitted pursuant to applicable law.
  The Selling Securityholders, which as
  used herein includes donees, pledgees, transferees, distributees or other successors-in-interest selling shares of our Class A common
  stock or interests in our Class A common stock received after the date of this prospectus from the Selling Securityholders as a gift,
  pledge, partnership distribution or other transfer, may, from time to time, sell, transfer, distribute or otherwise dispose of certain
  of their shares of Class A common stock or interests in our Class A common stock on any stock exchange, market or trading facility on
  which shares of our Class A common stock, as applicable, are traded or in private transactions. These dispositions may be at fixed prices,
  at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the
  time of sale, or at negotiated prices.
  In addition, any securities that qualify
  for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.
  7
  To the extent required, this prospectus may be
  amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the securities
  or otherwise, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions. In
  connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the securities in the course
  of hedging the positions they assume with Selling Securityholders. The Selling Securityholders may also sell the securities short and
  redeliver the securities to close out such short positions. The Selling Securityholders may also enter into option or other transactions
  with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of
  securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this
  prospectus (as supplemented or amended to reflect such transaction).
  A Selling Securityholder that is an entity
  may elect to make an in-kind distribution of Class A common stock to its members, partners or shareholders pursuant to the registration
  statement of which this prospectus is a part by delivering a prospectus. To the extent that such members, partners or shareholders are
  not affiliates of ours, such members, partners or shareholders would thereby receive freely tradable shares of Class A common stock pursuant
  to the distribution through a registration statement.
  The Selling Securityholders may also
  pledge securities to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution,
  may effect sales of the pledged securities pursuant to this prospectus (as supplemented or amended to reflect such transaction).
  A Selling Securityholder may enter into
  derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately
  negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties
  may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If
  so, the third party may use securities pledged by any Selling Securityholder or borrowed from any Selling Securityholder or others
  to settle those sales or to close out any related open borrowings of stock, and may use securities received from any Selling
  Securityholder in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale
  transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment).
  In addition, any Selling Securityholder may otherwise loan or pledge securities to a financial institution or other third party that
  in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its
  economic short position to investors in our securities or in connection with a concurrent offering of other securities.
  In effecting sales, broker-dealers or
  agents engaged by the Selling Securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive
  commissions, discounts or concessions from the Selling Securityholders in amounts to be negotiated immediately prior to the sale.
  In offering the securities covered by
  this prospectus, the Selling Securityholders and any broker-dealers who execute sales for the Selling Securityholders may be deemed to
  be "underwriters" within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling
  Securityholders and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions.
  In order to comply with the securities
  laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or
  dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable
  state or an exemption from the registration or qualification requirement is available and is complied with.
  We have advised the Selling Securityholders
  that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of securities in the market and to the activities
  of the Selling Securityholders and their affiliates. In addition, we will make copies of this prospectus available to the Selling Securityholders
  for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholders may indemnify any
  broker-dealer that participates in transactions involving the sale of the securities against certain liabilities, including liabilities
  arising under the Securities Act.
  8
  At the time a particular offer of securities
  is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms
  of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission
  and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed
  selling price to the public.
  Certain agents, underwriters and dealers,
  and their associates and affiliates, may be customers of, have borrowing relationships with, engage in other transactions with, or perform
  services, including investment banking services, for us or one or more of our respective affiliates and/or the Selling Securityholders
  or one or more of its respective affiliates in the ordinary course of business for which they receive compensation.

  Not applicable.
  Item 5. Interests of Named Experts and Counsel.
  The validity of the issuance of the shares of Class A common stock
  is being passed upon for the Registrant by Orrick, Herrington & Sutcliffe LLP. A copy of this opinion is attached as Exhibit 5.1 to
  this Registration Statement.
  Item 6. Indemnification of Directors and Officers.
  Section 145 of the Delaware General Corporation Law (the "DGCL")
  provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including
  attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection
  with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person
  being or having been 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. The DGCL provides
  that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaws, agreement,
  vote of stockholders or disinterested directors or otherwise. The Registrant's Second Amended and Restated Certificate of Incorporation
  and Amended and Restated Bylaws provide for indemnification by the Registrant of its directors and officers to the fullest extent permitted
  by the DGCL.
  II-
  1
  Section 102(b)(7) of the DGCL permits a corporation to provide in its
  certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders
  for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director's duty
  of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct
  or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions
  or (4) for any transaction from which the director derived an improper personal benefit. The Registrant's Second Amended and Restated
  Certificate of Incorporation provides for such limitation of liability to the fullest extent permitted by the DGCL.
  The registrant has entered into, and expects to continue to enter into,
  indemnification agreements with each of its directors and executive officers. These agreements provide that the registrant will indemnify
  each of its directors and such officers to the fullest extent permitted by law.
  Any underwriting agreement or distribution agreement
  that the Registrant enters into with any underwriters or agents involved in the offering or sale of any securities registered hereby may
  require such underwriters or dealers to indemnify the Registrant, some or all of its directors and officers and its controlling persons,
  if any, for specified liabilities, which may include liabilities under the Securities Act.
  The Registrant also maintains standard policies of insurance under
  which coverage is provided to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful
  act, while acting in their capacity as directors and officers of the Registrant.
  See also the undertakings set out in response to Item 9 hereof.
  Item 7. Exemption from Registration Claimed.
  The shares being reoffered and resold pursuant to the Reoffer Prospectus
  were deemed to be exempt from registration under the Securities Act in reliance on Section 4(a)(2) of the Securities Act and/or Rule 701
  promulgated thereunder, as transactions by an issuer not involving a public offering or pursuant to a written compensatory benefit plan.

  Item 9. Undertakings.
  a.
  The undersigned Registrant hereby undertakes:
  (1)
  To file, during any period in which offers or sales are being made,
      a post-effective amendment to this Registration Statement:
  (i)
  To include any prospectus required by Section 10(a)(3) of the Securities Act;
  (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 the 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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;
  (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 paragraphs (a)(1)(i) and (a)(1)(ii)
  above do not apply if the information required to be included in a post-effective amendment by such paragraphs is contained in reports
  filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated
  by reference in the Registration Statement.
  (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.
  II-
  3
  (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.
  b.
  The undersigned Registrant hereby undertakes that, for purposes 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 the 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 Commission 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 hereby, 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.
  II-
