VectoIQ Acquisition Corp. II, a corporation organized and existing under the laws of the State of Delaware (the “Corporation”), DOES HEREBY CERTIFY AS FOLLOWS:

1.             The name of the Corporation is “VectoIQ Acquisition Corp. II”. The original certificate of incorporation of the Corporation was filed with the Secretary of State of the State of Delaware on August 10, 2020 (as subsequently amended prior to January 6, 2021, the “Original Certificate”). The Amended and Restated Certificate of Incorporation of the Corporation (the “Amended and Restated Certificate”) was filed with the Secretary of State of the State of Delaware on January 6, 2021.

2.             This Amendment to the Amended and Restated Certificate of Incorporation (“Amendment”) amends the Amended and Restated Certificate.

3.             This Amendment was duly adopted by the Board of Directors of the Corporation and the stockholders of the Corporation in accordance with Sections 228 and 242 of the General Corporation Law of the State of Delaware.

4.             The text of Section 9.1(b) is hereby amended and restated to read in full as follows:

(b) Immediately after the Offering, a certain amount of the net offering proceeds received by the Corporation in the Offering (including the proceeds of any exercise of the underwriters’ over-allotment option) and certain other amounts specified in the Corporation’s registration statement on Form S-1, as initially filed with the Securities and Exchange Commission (the “SEC”) on December 18, 2020, as amended (the “Registration Statement”), were deposited in a trust account (the “Trust Account”), established for the benefit of the Public Stockholders (as defined below) pursuant to a trust agreement described in the Registration Statement. Except for the withdrawal of interest income (if any) to pay the Corporation’s taxes, if any, and up to $250,000 per year for working capital purposes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earlier to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation does not complete its initial Business Combination by December 9, 2022, subject to applicable law, and (iii) the redemption of Offering Shares in connection with a stockholder vote to approve an amendment to this Amended and Restated Certificate that (A) would affect the substance or timing of the Corporation’s obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Offering Shares if the Corporation has not completed an initial Business Combination by December 9, 2022, or (B) with respect to stockholders’ rights or pre-initial Business Combination activity (as described in Section 9.7). Holders of shares of the Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are the Sponsor or officers or directors of the Corporation, or any affiliates of any of the foregoing) are referred to herein as “Public Stockholders.”

5.             The text of Sections 9.2(a), 9.2(d), 9.2(e) and 9.2(f) are hereby amended and restated to read in full as follows:

(a) Prior to the consummation of the initial Business Combination, the Corporation shall provide all holders of Offering Shares with the opportunity to have their Offering Shares redeemed upon the consummation of the initial Business Combination pursuant to, and subject to the limitations of, Sections 9.2(b) and 9.2(c) (such rights of such holders to have their Offering Shares redeemed pursuant to such Sections, the “Redemption Rights”) hereof for cash equal to the applicable redemption price per share determined in accordance with Section 9.2(b) hereof (the “Redemption Price”). Notwithstanding anything to the contrary contained in this Amended and Restated Certificate, there shall be no Redemption Rights or liquidating distributions with respect to any warrant issued pursuant to the Offering.

(d) In the event that the Corporation has not completed an initial Business Combination by December 9, 2022, the Corporation shall (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the Offering Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest, divided by the number of the then outstanding Offering Shares, which redemption will completely extinguish rights of the Public Stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board in accordance with applicable law if such approval has not previously been obtained, liquidate and dissolve, subject in each case to the Corporation’s obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law.

(e) If the Corporation offers to redeem the Offering Shares in conjunction with a stockholder vote on an initial Business Combination, the Corporation shall consummate the proposed initial Business Combination only if such initial Business Combination is approved by the affirmative vote of the holders of a majority of the shares of the Common Stock that are voted at a stockholder meeting held to consider such initial Business Combination.

(f) [RESERVED].

6.           The text of Section 9.7 is hereby deleted in its entirety and replaced as follows:

If, in accordance with Section 9.1(a), any amendment is made to Section 9.2(d) that would affect the substance or timing of the Corporation’s obligation to allow redemption in connection with the Corporation’s initial Business Combination or to redeem 100% of the Offering Shares if the Corporation does not complete an initial Business Combination by December 9, 2022, or with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity, the Public Stockholders shall be provided with the opportunity to redeem their Offering Shares upon approval of any such amendment, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Corporation to fund its working capital requirements (subject to a limit of $250,000 per year) and/or to pay its taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of the then outstanding Offering Shares.
