 Exhibit 10.6 

FORWARD PURCHASE AGREEMENT 

This Forward Purchase Agreement (this “Agreement”) is entered into as of October 1, 2020, by and
between Avanti Acquisition Corp., a Cayman Islands exempted company (the “Company”), and the party listed as the purchaser on the signature page hereof (the “Purchaser”). 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization
or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the Company has
filed with the U.S. Securities and Exchange Commission (the “SEC”) registration statements on Form S-1 (the “Registration Statements”) for its
initial public offering (“IPO”) of units (the “Public Units”) at a price of $10.00 per Public Unit, each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the
“Class A Share(s)” and the Class A Shares included in the Public Units, the “Public Units”), and one-half of one redeemable
warrant, where each whole redeemable warrant is exercisable to purchase one Class A Share at an exercise price of $11.50 per share (the “Warrant(s)”); 

WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to identify and consummate a
Business Combination; 
 WHEREAS, the parties wish to enter into this Agreement, pursuant to which immediately prior to the closing of the
Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Purchaser shall purchase, on a private placement basis, up to $100,000,000 of units, at a price of
$10.00 per unit, each unit comprised of one Class A ordinary share, par value of $0.0001 per share (the “Forward Purchase Shares”); and one-half of one warrant to purchase one
Class A ordinary share at an exercise price of $11.50, subject to adjustment (the “Forward Purchase Warrants” and together with the Forward Purchase Shares, the “Forward Purchase Securities”) on
the terms and conditions set forth herein; 
 WHEREAS, proceeds from the IPO and the sale of the Private Placement Warrants in an aggregate
amount equal to the gross proceeds from the IPO will be deposited into a trust account for the benefit of the holders of the Public Shares (the “Trust Account”), as described in the Registration Statements; and 

WHEREAS, the amounts available to the Company from the Trust Account (after giving effect to any redemptions of Public Shares) and any other
equity or debt financing obtained by the Company in connection with the Business Combination (the “Available Cash”), together with the proceeds from the sale of the Forward Purchase Units, will be used to satisfy the cash
requirements of the Business Combination, including funding the purchase price and paying expenses and retaining amounts specified in the definitive agreement for the Business Combination (the “Definitive Agreement”) to be
retained for use by the post-Business Combination company for working capital or other purposes (the “Cash Requirements”); 

NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for
other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

1.    Sale and Purchase. 

(a)    Forward Purchase Securities. 

(i)    Subject to Section 1(a)(iii), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase
from the Company, (1) up to a maximum number of Forward Purchase Shares which is the quotient of (x) $100,000,000, and (y) $10.00 (the “Number of Forward Purchase Shares”), plus (2) the number of Forward
Purchase Warrants which is the product of 

 
(x) the number of Forward Purchase Shares as determined by clause (1) and (y) 1/2, the “Number of Forward Purchase Warrants”, for an aggregate purchase
price of $10.00 multiplied by the number of Forward Purchase Shares issued and sold hereunder (the “FPS Purchase Price”). No fractional Forward Purchase Warrants will be issued and, upon issuance, the Number of Forward
Purchase Warrants shall be rounded down to the nearest whole number of Warrants. 
 (ii)    Each Forward Purchase
Warrant will have the same terms as the Company’s private placement warrants purchased by the Purchaser in a private placement occurring simultaneously with the closing of the IPO so long as these are held by the Purchaser or its permitted
assignees and transferees, and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection with the IPO (the
“Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement and only whole
Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable on the later of 30 days after the Business Combination Closing and 12 months from the IPO Closing, and will expire five years after the
Business Combination Closing or earlier upon redemption or the liquidation of the Company, as described in the Warrant Agreement. 
 (iii)
The Company shall deliver written notice (the “Company Notice”) to the Purchaser as early as practicable, and in any case five (5) Business Days prior to the Company entering into a definitive agreement with respect to the
applicable Business Combination and at least eleven (11) Business Days before the funding of the FPS Purchase Price, specifying the anticipated date of the Business Combination Closing, the aggregate FPS Purchase Price and instructions for wiring
the FPS Purchase Price to the account of the Company. The FPS Purchase Price shall be equal to the Company’s good faith estimate of that number which, after payment of the aggregate FPS Purchase rice by the Purchaser, will result in gross
proceeds to the Company equal to the amount of funds necessary for the Company to satisfy the Cash Requirements less the Available Cash; provided, however, that such number shall in no event exceed
$100,000,000; and provided, further, that, notwithstanding the foregoing, the Purchaser shall in any event have the option to purchase up to $100,000,000 of Forward Purchase Securities. 

(iv) Within five (5) Business Days after receipt of the Company Notice, the Purchaser shall provide the Company with notice (the
“Purchaser Notice”) of the decision of its investment committee or board of directors as to the number of Forward Purchase Units it wishes to purchase pursuant to this Agreement, if any, which shall not exceed $100,000,000 of
Forward Purchase Securities, which notice shall constitute the binding obligation of the Purchaser to purchase such number of Forward Purchase Securities, subject to the terms and conditions of this Agreement. 

(v) Two (2) Business Days before the anticipated date of the Business Combination Closing specified by the Company, the Purchaser shall
deliver the FPS Purchase Price in cash via wire transfer to the account specified in such written notice. If the Business Combination Closing does not occur within thirty (30) days after the Purchaser delivers the FPS Purchase Price to the Company,
the Company shall automatically return to the Purchaser the FPS Purchase Price; provided that the return of the FPS Purchase Price shall not terminate the Agreement or otherwise relieve either party of any of its obligations hereunder. The Purchaser
agrees that it shall cooperate in good faith and use reasonable best efforts to effect the funding of the FPS Purchase Price on such notice as necessary to facilitate the consummation of the proposed Business Combination. For the purposes of this
Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City of New York,
New York. 
 (vi)    The closing of the sale of the Forward Purchase Securities (the “FPS
Closing”) shall be held on the same date as, and immediately prior to, the Business Combination Closing (such date being referred to as the “Closing Date”). At the FPS Closing, the Company will issue to the
Purchaser the Forward Purchase Securities. 
 (b)    Delivery of Forward Purchase Securities. 

(i)    The Company shall register the Purchaser as the owner of the Forward Purchase Securities purchased by the
Purchaser hereunder in the register of members of the Company, if applicable, and with the Company’s transfer agent by book entry on or promptly after (but in no event more than two (2) Business Days after) the date of the FPS Closing.

  
 2 

 (ii)    Each register and book entry for the Forward Purchase
Securities purchased by the Purchaser hereunder shall contain a notation, and each certificate (if any) evidencing the Forward Purchase Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF
ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.” 

(c)    Legend Removal. If the Forward Purchase Securities are eligible to be sold without restriction under, and
without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), then at the Purchaser’s request, the Company
will, at its sole expense, cause the Company’s transfer agent to remove the legend set forth in Section 1(b)(ii) hereof. In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an
opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent, that authorize and direct the transfer agent to transfer such Forward
Purchase Securities without any such legend; provided, however, that the Company will not be required to deliver any such opinion, authorization or certificate or direction if it reasonably believes that removal of the legend could
reasonably be expected to result in or facilitate transfers of Forward Purchase Securities in violation of applicable law. 

(d)    Registration Rights. The Purchaser shall have registration rights in accordance with the Registration and
Shareholder Rights Agreement dated on or about the date hereof and between, among others, the Company and the Purchaser (the “Registration Rights”). 

2.    Representations and Warranties of the Purchaser. The Purchaser represents and warrants to the Company
as follows, as of the date hereof: 
 (a)    Organization and Power. The Purchaser is duly organized, validly
existing, and in good standing under the laws of the jurisdiction of its formation (if the concept of “good standing” is a recognized concept in such jurisdiction) and has all requisite power and authority to carry on its business as
presently conducted and as proposed to be conducted. 
 (b)    Authorization. The Purchaser has full power and
authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of
specific performance, injunctive relief or other equitable remedies, or (iii) to the extent the indemnification provisions contained in the Registration Rights may be limited by applicable federal or state securities laws. 

  
 3 

 (c)    Governmental Consents and Filings. No consent, approval,
order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions
contemplated by this Agreement. 
 (d)    Compliance with Other Instruments. The execution, delivery and
performance by the Purchaser of this Agreement and the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, if
applicable, (ii) of any instrument, judgment, order, writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease,
agreement, contract or purchase order to which it is a party or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would
have a material adverse effect on the Purchaser or its ability to consummate the transactions contemplated by this Agreement. 

(e)    Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the
Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Forward Purchase Securities to be acquired by the Purchaser will be acquired for investment for the
Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the
same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such
Person or to any third Person, with respect to any of the Forward Purchase Securities. If the Purchaser was formed for the specific purpose of acquiring the Forward Purchase Securities, each of its equity owners is an accredited investor as defined
in Rule 501(a) of Regulation D promulgated under the Securities Act. For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust,
an unincorporated organization, any other entity or any government or any department or agency thereof. 

(f)    Disclosure of Information. The Purchaser has had an opportunity to discuss the Company’s business,
management, financial affairs and the terms and conditions of the offering and sale of the Forward Purchase Securities, as well as the terms of the IPO, with the Company’s management. 

(g)    Restricted Securities. The Purchaser understands that the offer and sale of the Forward Purchase Securities
to the Purchaser has not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the
investment intent and the accuracy of the Purchaser’s representations as expressed herein. The Purchaser understands that the Forward Purchase Securities are “restricted securities” under applicable U.S.

  
 4 

 
federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Securities indefinitely unless they are registered with the SEC and qualified by
state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Forward Purchase Securities, or any Class A Shares
which the Forward Purchase Securities may be converted into or exercised for, for resale, except pursuant to the Registration Rights. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be
conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Forward Purchase Securities, and requirements relating to the Company which are outside of the Purchaser’s control, and
which the Company is under no obligation and may not be able to satisfy. The Purchaser acknowledges that the Company filed the Registration Statements for the IPO with the SEC. The Purchaser understands that the offering of the Forward Purchase
Securities hereunder is not, and is not intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act with respect to such offering of the Forward Purchase Securities.

 (h)    No Public Market. The Purchaser understands that no public market now exists for the Forward Purchase
Securities, and that the Company has made no assurances that a public market will ever exist for the Forward Purchase Securities. 

(i)    High Degree of Risk. The Purchaser understands that its agreement to purchase the Forward Purchase
Securities involves a high degree of risk which could cause the Purchaser to lose all or part of its investment. 

(j)    Accredited Investor. The Purchaser is an “accredited investor” as defined in
Rule 501(a) of Regulation D promulgated under the Securities Act. 
 (k)    Foreign Investors. If the
Purchaser is not a United States person (as defined by Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended), the Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its
jurisdiction in connection with any invitation to subscribe for the Forward Purchase Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Forward Purchase Securities,
(ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the
purchase, holding, redemption, sale, or transfer of the Forward Purchase Securities. The Purchaser’s subscription and payment for and continued beneficial ownership of the Forward Purchase Securities will not violate any applicable securities
or other laws of the Purchaser’s jurisdiction. 
 (l)    No General Solicitation. Neither the Purchaser, nor
any of its officers, directors, employees, agents, stockholders or partners has either directly or indirectly, including through a broker or finder, (i) to its knowledge, engaged in any general solicitation, or (ii) published any
advertisement in connection with the offer and sale of the Forward Purchase Securities. 
 (m)    Residence. The
principal place of business of the Purchaser is the office located at the address of the Purchaser set forth on the signature page hereof. 

  
 5 

 (n)    Non-Public
Information. The Purchaser acknowledges its obligations under applicable securities laws with respect to the treatment of material non-public information relating to the Company. 

(o)    Adequacy of Financing. The Purchaser has, or will have, from and after receipt of capital commitments not
subject to opt-out rights (or for which the party with such opt-out rights has agreed to fund in respect of this Agreement) in an aggregate amount not less than the FPS
Purchase Price, available to it sufficient funds to satisfy its obligations under this Agreement. 

(p)    Affiliation of Certain FINRA Members. The Purchaser is neither a person associated nor affiliated with any
underwriter of the IPO or, to its actual knowledge, any other member of the Financial Industry Regulatory Authority (“FINRA”) that is participating in the IPO. 

(q)    No Other Representations and Warranties; Non-Reliance. Except for
the specific representations and warranties contained in this Section 2 and in any certificate or agreement delivered pursuant hereto, none of the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s
affiliates (the “Purchaser Parties”) has made, makes or shall be deemed to make any other express or implied representation or warranty with respect to the Purchaser and the offering, sale and purchase of the Forward Purchase
Securities, and the Purchaser Parties disclaim any such representation or warranty. Except for the specific representations and warranties expressly made by the Company in Section 3 of this Agreement and in any certificate or agreement
delivered pursuant hereto, the Purchaser Parties specifically disclaim that they are relying upon any other representations or warranties that may have been made by the Company, any person on behalf of the Company or any of the Company’s
affiliates (collectively, the “Company Parties”).

Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and
all types of direct and indirect stock pledges 

  
 9 

 
(other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total
return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. 

5.    Additional Agreements of the Company.

of the Class A Shares on the NYSE (or another national securities exchange). 
 (c)    No Amendments to the

Closing without the Purchaser’s prior written consent.

warranty that is made by its terms as of a specified date, which shall be true and correct as of such specified date), except where the failure to be so true and correct would not have a material adverse effect on the Company or its ability to
consummate the transactions contemplated by this Agreement;

material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Company at or prior to the FPS Closing;

not have a material adverse effect on the Purchaser or its ability to consummate the transactions contemplated by this Agreement;

time prior to the FPS Closing:

employees, partners, managers, members, or shareholders and all rights and obligations of each party shall cease; provided, however, that nothing contained in this Section 7 shall relieve either party from liabilities or damages
arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants or agreements contained in this Agreement. Section 4(a) shall survive termination of this Agreement.

or financial advisor who assists the Company in sourcing targets for a Business Combination, which fees shall be the responsibility of the Company, each party represents that it neither is nor will be obligated for any finder’s fee or
commission in connection with this transaction. The Purchaser agrees to indemnify and to hold harmless the Company from 

  
 12 

 
any liability for any commission or compensation in the nature of a finder’s or broker’s fee arising out of this transaction (and the costs and expenses of defending against such
liability or asserted liability) for which the Purchaser or any of its officers, employees or representatives is responsible. The Company agrees to indemnify and hold harmless the Purchaser from any liability for any commission or compensation in
the nature of a finder’s or broker’s fee arising out of this transaction (and the costs and expenses of defending against such liability or asserted liability) for which the Company or any of its officers, employees or representatives is
responsible. 
 (c)    Survival of Representations and Warranties. All of the representations and warranties
contained herein shall survive the FPS Closing. 
 (d)    Entire Agreement. This Agreement, together with any
documents, instruments and writings that are delivered pursuant hereto or referenced herein, constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings,
agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. 

(e)    Successors. All of the terms, agreements, covenants, representations, warranties, and conditions of this
Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties hereto and their respective successors. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

(f)    Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this
Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other party. Notwithstanding the foregoing, the Purchaser may assign and delegate all or a portion of its rights and obligations to purchase
the Forward Purchase Securities to one or more other persons upon the consent of the Company (which consent shall not be unreasonably conditioned, withheld or delayed); provided, however, that no consent of the Company shall be
required if such assignment or delegation is to an affiliate of Purchaser; provided, further, that no such assignment or delegation shall relieve the Purchaser of its obligations hereunder (including its obligation to purchase the
Number of Forward Purchase Shares and the Number of Forward Purchase Warrants hereunder) and the Company shall be entitled to pursue all rights and remedies against the Purchaser subject to the terms and conditions hereof. 

(g)    Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an
original but all of which together will constitute one and the same instrument. 
 (h)    Headings. The section
headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement. 

  
 13 

 (i)    Governing Law. This Agreement, the entire relationship of
the parties hereto, and any dispute between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of New York, without giving
effect to its choice of laws principles. 
 (j)    Jurisdiction. The parties (i) hereby irrevocably and
unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding arising out of or
based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of New York,
and (iii) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property
is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be
enforced in or by such court. 
 (k)    Waiver of Jury Trial. The parties hereto hereby waive any right to a jury
trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby. 

(l)    Amendments. This Agreement may not be amended, modified or waived as to any particular provision, except
with the prior written consent of the Company and the Purchaser. 
 (m)    Severability. The provisions of this
Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party
hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such
determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will
be enforced. 
 (n)    Expenses. Each of the Company and the Purchaser will be responsible for payment of its own
costs and expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors,
legal counsel and accountants. The Company shall be responsible for the fees of its transfer agent; stamp taxes and all of The Depository Trust Company’s fees associated with the issuance and resale of the Forward Purchase Securities and the
securities issuable upon conversion or exercise of the Forward Purchase Securities. 
 (o)    Construction. The
parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation 

  
 14 

 
arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the
authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires
otherwise. 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 Agreement,” “herein,”
“hereof,” “hereby,” “hereunder,” and words of similar import refer to this 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. 
 (p)    Waiver. No waiver by any party hereto of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights
arising because of any prior or subsequent occurrence. 
 (q)    Confidentiality. Except as may be required by
law, regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep
confidential and shall not publicly disclose the existence or terms of this Agreement. 
 (r)    Specific
Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of this Agreement was not performed by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific
performance of the terms hereof, in addition to any other remedy at law or equity.
