At or prior to the Effective Time, AIR shall deposit, or shall cause to be deposited, with Broadridge Corporate Issuer Solutions (the “Transfer Agent”), in trust for the benefit of the Tenax Members, a number of shares of AIR Common Stock, in book-entry or certificated form, equal to the portion of the Merger Consideration issuable to the Tenax Members in accordance with the Tenax Closing Capitalization Schedule for the purpose of exchanging Tenax Units for the Merger Consideration.

(b) Exchange Procedures. Prior to the Effective Time, Tenax will provide to each Person who is or will be, as of immediately prior to the Effective Time, a Tenax Member a letter of transmittal, which shall contain customary representations and warranties of the type commensurate with a private placement of securities exempt from registration under the Securities Act and such other provisions as Tenax may reasonably specify (including a provision confirming that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of such letter of transmittal). Upon delivery to the Transfer Agent of such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Transfer Agent or Tenax, the Tenax Member will be entitled to receive (following the Effective Time) in exchange such Tenax Member’s Tenax Units, the portion of the Merger Consideration allocated to such Tenax Member in accordance with the Tenax Closing Capitalization Schedule (together with cash in lieu of fractional shares), and such Tenax Member’s Tenax Units will forthwith be canceled. Until exchanged as contemplated by this Section 3.06, any Tenax Units will be deemed at any time after the Effective Time to represent only the right to receive upon such exchange Merger Consideration as contemplated by this Section 3.06. No interest will be paid or accrue on any cash payable upon exchange of any Tenax Units.

Section 3.07 No Fractional Shares.

(a) No certificates or scrip representing fractional shares of AIR Common Stock will be issued upon the conversion of Tenax Units pursuant to Section 3.06, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a holder of AIR Common Stock. For purposes of this Section 3.07, all fractional shares to which a single record holder would be entitled will be aggregated, and calculations will be rounded up to three decimal places.

(b) Fractional shares of AIR Common Stock that would otherwise be allocable to any former Tenax Members in the Merger will be aggregated, and no Tenax Members will receive cash in exchange therefor equal to or greater than the value of one full share of AIR Common Stock. The Transfer Agent will cause the whole shares obtained thereby to be sold, in the open market or otherwise as reasonably directed by AIR, and in no case later than 20 Business Days after the Effective Time (assuming all Tenax Units have been surrendered pursuant to Section 3.06 by such date). The Transfer Agent will make available the net proceeds thereof, after deducting any required withholding Taxes and brokerage charges, commissions and transfer Taxes, on a pro rata basis, without interest, as soon as practicable to the Tenax Members entitled to receive such cash. Payment of cash in lieu of fractional shares of AIR Common Stock will be made solely for the purpose of avoiding the expense and inconvenience to AIR of issuing fractional shares of AIR Common Stock and will not represent separately bargained-for consideration.

Section 3.08 No Liability. None of the parties hereto, the Surviving Company or the Transfer Agent will be liable to any Person in respect of any shares of AIR Common Stock properly delivered to any public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 3.09 Further Action. If, at any time after the Effective Time, any further action is determined by AIR or Tenax to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Company with full right, title and possession, and to all rights and property, of Merger Sub and Tenax, the officers and directors of the Surviving Company and AIR shall be fully authorized (in the name of Merger Sub, in the name of Tenax, and otherwise) to take such action.

Section 3.10 AIR Equity Awards. Each AIR Equity Award that is then outstanding as of immediately prior to the Effective Time shall continue on the same terms and conditions as were applicable to such AIR Equity Award as of immediately prior to the Effective Time. At or prior to the Effective Time, AIR, the AIR Board and the Compensation Committee of the AIR Board, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of this Section 3.10.

Subject to the terms of this Agreement, the AIR Board shall recommend that the stockholders of AIR vote in favor of the approval of the AIR Charter Amendment and the AIR Stock Issuance. AIR shall comply with the NRS, AIR’s articles of incorporation and bylaws, the Exchange Act and the rules and regulations of NYSE American in connection with the AIR Stockholders Meeting, including preparing and delivering the Proxy Statement to AIR’s stockholders, as required pursuant to the Exchange Act and Section 7.01(b) below. Subject to the terms of this Agreement, unless there has been a Change in the AIR Recommendation, AIR shall use its reasonable best efforts to solicit (or cause to be solicited) from its stockholders proxies constituting the AIR Stockholder Approvals. AIR shall not change the date of, postpone or adjourn the AIR Stockholders Meeting without the consent of Tenax (which may not be unreasonably withheld, conditioned or delayed); provided that, without Tenax’s consent, AIR may adjourn or postpone the AIR Stockholders Meeting as may be required by applicable Law and no more than two times (i) to ensure that any required supplement or amendment to the Proxy Statement is provided to AIR’s stockholders within a reasonable amount of time in advance of the AIR Stockholders Meeting, (ii) to allow reasonable additional time to solicit from its stockholders proxies in favor of approval of the AIR Charter Amendment and the AIR Stock Issuance, (iii) if, as of the time for which the AIR Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement) or the time scheduled for reconvening the AIR Stockholders Meeting, there are insufficient shares of AIR Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the AIR Stockholders Meeting or at such time AIR has not received proxies sufficient to allow the receipt of the AIR Stockholder Approvals at the AIR Stockholders Meeting or (iv) as required by applicable Law; provided further that the AIR Stockholders Meeting shall not be postponed, recessed or adjourned pursuant to this proviso to a date that is more than 30 days after the date on which the AIR Stockholders Meeting was originally scheduled without the prior written consent of Tenax. Tenax may cause AIR to postpone or adjourn the AIR Stockholders Meeting by prior written notice to AIR once for a period of no longer than ten Business Days if at such time AIR has not received proxies sufficient to allow the receipt of the AIR Stockholder Approvals at the AIR Stockholders Meeting and Tenax informs AIR that Tenax believes in good faith that additional time is required to solicit stockholder proxies in favor of approval of the AIR Charter Amendment and the AIR Stock Issuance.

(b) Promptly following the date of this Agreement, and in any event no later than ten Business Days following the delivery by Tenax of all financial statements that are required by the applicable accounting requirements and other rules and regulations of the SEC to be included in the Proxy Statement together with information relating to it required to be included in the Proxy Statement by Regulation 14A under the Exchange Act or other applicable Law, AIR, with the assistance of Tenax, shall prepare, and AIR shall file with the SEC, the preliminary Proxy Statement and any amendments or supplements thereto in form and substance reasonably satisfactory to each of AIR and Tenax relating to the Merger and the Transactions. Subject to the terms of this Agreement, the Proxy Statement shall reflect the AIR Recommendation. Tenax shall, and shall use its reasonable best efforts to cause its Representatives and Affiliates to, cooperate with AIR in the preparation of the preliminary Proxy Statement and the definitive Proxy Statement and shall furnish to AIR all information relating to it required by the Exchange Act for inclusion in, or to assist AIR in preparing, the Proxy Statement (and responding to any comments from the SEC or its staff with respect thereto), including, without limitation, such financial statements and other information relating to it and its Affiliates required to be included in the Proxy Statement by Regulation 14A under the Exchange Act or other applicable Law. In addition, Tenax shall use its reasonable best efforts to cause its independent accountants to provide assistance and cooperation to AIR in connection with the preparation of the Proxy Statement, including, without limitation, to the extent required by applicable Law, providing consent to AIR to include their audit reports in the Proxy Statement and providing reasonable assistance in the preparation of pro forma financial statements to be included in the Proxy Statement. AIR shall promptly provide Tenax and its counsel with copies of any written comments, and shall inform them of any oral comments, that AIR or its counsel may receive from the SEC or its staff with respect to any preliminary Proxy Statement, and AIR shall use its reasonable best efforts, after consultation with and with the assistance of Tenax, to respond as promptly as practicable to any such comments of the SEC or its staff and to cause the Proxy Statement in definitive form to be mailed to AIR’s stockholders at the earliest practicable time. Each of AIR and Tenax shall promptly advise the other if it determines that any information provided by it for use in the Proxy Statement was or shall have become false or misleading in any material respect and shall promptly notify the other if it becomes aware of any material fact not contained in the Proxy Statement and required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. AIR shall take all steps necessary to cause the Proxy Statement as so corrected to be filed with the SEC and to be disseminated to holders of shares of AIR Stock, in each case as, and to the extent, required by applicable Law. AIR shall promptly provide Tenax and its counsel with copies of any written comments, and shall inform them of any oral comments, that AIR or its counsel may receive from the SEC or its staff requesting any amendments or supplements to the preliminary Proxy Statement or the definitive Proxy Statement, and AIR and Tenax shall cooperate in filing with the SEC or its staff, and if required by applicable Law, AIR shall mail to its stockholders, as promptly as reasonably practicable, such amendment or supplement. AIR shall provide Tenax and its counsel a reasonable opportunity to review any written responses to all SEC comments with respect to a preliminary or definitive Proxy Statement, and AIR shall give due consideration to the reasonable additions, deletions or changes suggested thereto by Tenax and its counsel.

Section 7.02 No Solicitation of Transactions.

(a) AIR agrees that none of it or any of its Subsidiaries or any of their respective Representatives will, and that it will cause each of its Subsidiaries and each of its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could be reasonably be expected to lead to, any Competing AIR Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any Person or entity in furtherance of, or furnish to any Person any information or otherwise cooperate in any way with respect to, any Competing AIR Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing AIR Proposal; (iv) enter into, or propose to enter into, any Competing AIR Transaction Agreement; or (v) resolve, propose or agree, or authorize or permit any Representative, to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of AIR or any of its Subsidiaries shall be deemed to be a breach of this Section 7.02(a) by AIR. AIR shall, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons conducted prior to the execution of this Agreement by AIR, any of its Subsidiaries or its or any of their respective Representatives with respect to any Competing AIR Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing AIR Proposal previously granted to such Person.

(b) AIR shall promptly, and in any event within 24 hours of AIR obtaining knowledge of the receipt thereof, advise Tenax orally and in writing of any Competing AIR Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing AIR Proposal, the financial and other material terms and conditions of any such Competing AIR Proposal or inquiry (including any changes thereto) and the identity of the Person making any such Competing AIR Proposal or inquiry. AIR shall (i) keep Tenax fully informed of the status and material details (including any change to the terms thereof) of any such Competing AIR Proposal or inquiry and (ii) provide to Tenax, as soon as practicable after receipt or delivery thereof (and in any event, within 24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing AIR Proposal or inquiry exchanged between AIR or any of its Subsidiaries (or their Representatives), on the one hand, and the Person making such Competing AIR Proposal or inquiry (or its Representatives), on the other hand.

(c) Notwithstanding anything to the contrary in this Agreement, at any time prior to the receipt of the AIR Stockholder Approvals, AIR may, subject to compliance with Section 7.02(b), furnish information to, and enter into discussions with, a Person who has made, after the date hereof, an unsolicited, written, bona fide Competing AIR Proposal so long as such Competing AIR Proposal did not result from a breach of this Section 7.02 and, prior to furnishing such information and entering into such discussions, the AIR Board has (i) reasonably determined, in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate Law) that (A) such Competing AIR Proposal constitutes, or is reasonably likely to lead to, a Superior Proposal and (B) the failure to furnish such information to, or enter into such discussions with, the Person who made such Competing AIR Proposal would violate the AIR Board’s fiduciary duties under the NRS, (ii) previously provided all such information to Tenax (or provides such information to Tenax substantially concurrent with the time it is provided to such Person) and (iii) obtained from such Person an Acceptable AIR Confidentiality Agreement.

(d) Except as set forth in this Section 7.02(d), neither the AIR Board nor any committee thereof shall (i) (A) fail to make, withdraw, qualify, modify or amend, or propose publicly to fail to make, withdraw, qualify, modify or amend, the AIR Recommendation or fail to include the AIR Recommendation in the Proxy Statement, (B) adopt or recommend, or propose publicly to adopt or recommend, any Competing AIR Proposal or (C) enter into any agreement relating to a Competing AIR Proposal (other than an Acceptable AIR Confidentiality Agreement); or (ii) make any public statement inconsistent with the AIR Recommendation (any of the actions described in the foregoing clauses (i) and (ii), a “Change in the AIR Recommendation”). Notwithstanding the foregoing, if at any time prior to the receipt of the AIR Stockholder Approvals and subject to compliance with Section 7.02(b), in response to the receipt of an unsolicited, written, bona fide Competing AIR Proposal received after the date hereof or the occurrence of an Intervening Event, the AIR Board determines in its good-faith judgment (after having received the advice of a financial advisor of nationally recognized reputation and outside legal counsel qualified to practice in the State of Nevada and experienced in matters of Nevada corporate Law) that the failure of the AIR Board to make a Change in the AIR Recommendation would violate the fiduciary duties of the AIR Board under the NRS, then the AIR Board may make a Change in the AIR Recommendation; provided, however, that no Change in the AIR Recommendation may be made that relates to a Competing AIR Proposal unless such Competing AIR Proposal constitutes a Superior Proposal; provided further that AIR shall not be entitled to exercise its right to make a Change in the AIR Recommendation until after the fifth Business Day following Tenax’s receipt of written notice from AIR advising Tenax that the AIR Board intends to make a Change in the AIR Recommendation (a “Notice of Adverse Recommendation”) and specifying the reasons therefor, including a description of any Intervening Event in reasonable detail or the terms and conditions of any Superior Proposal and including an unredacted copy of any proposed agreement (including schedules and exhibits thereto) relating to such Superior Proposal (it being understood and agreed that any material change regarding such Intervening Event, or any amendment to the financial terms or any other material term of such Superior Proposal, shall require a new Notice of Adverse Recommendation and a new three-Business-Day notice period). AIR agrees that, during the applicable five-Business-Day notice period prior to the AIR Board making a Change in the AIR Recommendation, AIR and its Representatives shall negotiate in good faith with Tenax and its Representatives regarding any revisions to the terms of this Agreement proposed by Tenax. In determining whether to make a Change in the AIR Recommendation, the AIR Board shall take into account any changes to the financial or other terms of this Agreement proposed by Tenax in response to a Notice of Adverse Recommendation or otherwise. At the end of the five-Business-Day notice period (or three-Business-Day notice period with respect to any material change regarding such Intervening Event, or any amendment to the financial terms or any other material term of such Superior Proposal) the AIR Board may effect a Change in the AIR Recommendation if the AIR Board shall again make a determination in good faith after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of this Agreement proposed by Tenax), that the Change in the AIR Recommendation is required to comply with the fiduciary duties of the AIR Board under the NRS and, if applicable, the Competing AIR Proposal continues to constitute a Superior Proposal.

(e) Notwithstanding anything in this Agreement to the contrary, in no event shall any Change in the AIR Recommendation (A) affect the validity and enforceability of this Agreement or the other Transaction Documents, including the obligations of AIR and AIR’s stockholders that are party to the Transaction Documents to consummate the Merger or the other Transactions or (B) cause any state corporate takeover statute or other similar statute to be applicable to the Merger or the other Transactions.

(f) Tenax agrees that neither it nor any of its Subsidiaries nor any of their respective Representatives will, and that it will cause each of its Subsidiaries and each of its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) solicit, initiate, seek or take any other action to facilitate or encourage the making, submission or announcement of any proposal that constitutes, or could reasonably be expected to lead to, any Competing Tenax Proposal; (ii) enter into, maintain, continue or participate in any discussions or negotiations with any Person or entity in furtherance of, or furnish to any Person any information or otherwise cooperate in any way with respect to, any Competing Tenax Proposal; (iii) agree to, approve, endorse, recommend or consummate any Competing Tenax Proposal; (iv) enter into, or propose to enter into, any Competing Tenax Transaction Agreement; or (v) resolve, propose or agree, or authorize or permit any Representative, to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in the preceding sentence by any Representative of Tenax or any of its Subsidiaries shall be deemed to be a breach of this Section 7.02(f) by Tenax. Tenax shall, and shall cause its Subsidiaries and its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Persons conducted prior to the execution of this Agreement by Tenax, any of its Subsidiaries or its or any of their respective Representatives with respect to any Competing Tenax Proposal, request the prompt return or destruction of all confidential information previously furnished and terminate access to any physical or electronic data rooms related to a potential Competing Tenax Proposal previously granted to such Person.

(g) Tenax shall promptly, and in any event within 24 hours of Tenax obtaining knowledge of the receipt thereof, advise AIR orally and in writing of any Competing Tenax Proposal or any inquiry relating to or that could reasonably be expected to lead to any Competing Tenax Proposal, the financial and other material terms and conditions of any such Competing Tenax Proposal or inquiry (including any changes thereto) and the identity of the Person making any such Competing Tenax Proposal or inquiry. Tenax shall (i) keep AIR fully informed of the status and material details (including any change to the terms thereof) of any such Competing Tenax Proposal or inquiry and (ii) provide to AIR, as soon as practicable after receipt or delivery thereof (and in any event, within 24 hours of such receipt or delivery), unredacted copies of all correspondence (other than non-substantive written correspondence) and other written material (including all draft and final versions (and any amendments thereto) of agreements (including schedules and exhibits thereto) and any comments thereon) relating to any such Competing Tenax Proposal or inquiry exchanged between Tenax or any of its Subsidiaries (or their Representatives), on the one hand, and the Person making such Competing Tenax Proposal or inquiry (or its Representatives), on the other hand.

(h) Notwithstanding anything to the contrary in this Agreement, at any time prior to the receipt of the AIR Stockholder Approvals, Tenax may, subject to compliance with Section 7.02(g), furnish information to, and enter into discussions with, a Person who has made, after the date hereof, an unsolicited, written, bona fide Competing Tenax Proposal so long as such Competing Tenax Proposal did not result from a breach of this Section 7.02 and, prior to furnishing such information and entering into such discussions, the Tenax Board has obtained from such Person an Acceptable Tenax Confidentiality Agreement.

Section 7.03 Access to Information; Confidentiality.

(a) Except as otherwise prohibited by applicable Law, from the date of this Agreement until the Effective Time, AIR shall, and shall cause its Subsidiaries to, (i) provide to Tenax and Tenax’s Representatives reasonable access during normal business hours upon reasonable prior notice to the officers, employees and other personnel, agents, properties, offices and other facilities of AIR and its Subsidiaries and to the books and records thereof and (ii) furnish promptly to Tenax such information concerning the business, properties, Contracts, assets, liabilities, personnel and other aspects of AIR and its Subsidiaries as Tenax or its Representatives may reasonably request (including for purposes of conducting regulatory compliance reviews and audits to allow Tenax to be in compliance with its policies and procedures and any applicable Law at the Effective Time); provided, however, that AIR shall not be required to provide access to or disclose any such information to the extent such access or disclosure would result in the loss of attorney-client privilege of AIR or any of its Subsidiaries (provided that AIR and its Subsidiaries shall use their reasonable best efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege).

(b) Except as otherwise prohibited by applicable Law, from the date of this Agreement until the Effective Time, Tenax shall, and shall cause its Subsidiaries to, provide to AIR and AIR’s Representatives reasonable access during normal business hours upon reasonable prior notice to Tenax’s personnel and records on a basis consistent with AIR’s access to such personnel and records prior to the date hereof in connection with AIR’s due diligence review of Tenax and its Subsidiaries in connection with the Transactions and as the parties shall determine is reasonably necessary to enable the AIR Board to fulfill its fiduciary duties under the NRS.

(c) All information obtained by the parties hereto pursuant to this Section 7.03 shall be kept confidential in accordance with the Confidentiality Agreement.

(d) No investigation pursuant to this Section 7.03 shall affect any representation, warranty, covenant or agreement in this Agreement of any party hereto or any condition to the obligations of the parties hereto.

Section 7.04 Employee Benefits Matters.

(a) For the period beginning on the Closing Date and continuing through the first anniversary of the Closing Date (or, if shorter, during the period of employment), AIR shall, or shall cause its Subsidiaries to, provide each employee of AIR or its Subsidiaries, as of immediately prior to the Effective Time, who continues to be employed by AIR or the Surviving Company after the Closing Date (collectively, the “Continuing Employees”) with (i) a base salary or wage rate, as applicable, and annual cash target bonus opportunity that is not less than the base salary or wage rate, as applicable, and annual target cash bonus opportunity provided to such Continuing Employee immediately prior to the Effective Time and (ii) other employee benefits (including severance benefits) that are no less favorable in the aggregate than either, as determined by AIR in its sole discretion, (A) the other employee benefits provided to such Continuing Employee by AIR and its Subsidiaries immediately prior to the Effective Time or (B) the other employee benefits provided to similarly situated employees of Tenax and its Subsidiaries immediately prior to the Effective Time. Notwithstanding anything herein to the contrary, effective from and after the Closing Date, the terms and conditions of employment for any Continuing Employee covered by an AIR Collective Bargaining Agreement shall continue to be governed by the applicable AIR Collective Bargaining Agreement until the expiration, modification or termination of such AIR Collective Bargaining Agreement in accordance with its terms or applicable Laws.

(b) Without limiting the generality of Section 10.05, the provisions of this Section 7.04 are for the sole benefit of the parties to this Agreement and nothing herein, express or implied, is intended or shall be construed to confer upon or give any Person (including, for the avoidance of doubt, any Continuing Employee or other current or former AIR Service Provider or Tenax Service Provider), other than the parties hereto and their respective permitted successors and assigns, any legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 7.04) under or by reason of any provision of this Agreement. Nothing contained in this Agreement, express or implied, shall (i) be treated as an amendment to any AIR Benefit Plan, Tenax Benefit Plan or other compensation or benefit plan, program, policy, agreement, arrangement or understanding for any purpose; (ii) obligate AIR or the Surviving Company or any of their respective Subsidiaries to (A) maintain any particular benefit plan or arrangement or (B) retain the employment of any particular employee; or (iii) prevent AIR or the Surviving Company or any of their respective Subsidiaries from amending or terminating any benefit plan or arrangement.

Section 7.05 Directors’ and Officers’ Indemnification and Insurance.

(a) AIR’s obligations with respect to all rights to indemnification and exculpation from liabilities, including advancement of expenses, for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors or officers of AIR as provided in the articles of incorporation and bylaws of AIR or any indemnification Contract between such directors or officers and AIR (in each case, as in effect on the date hereof) shall survive the Closing and shall continue in full force and effect in accordance with their terms. For the avoidance of doubt, the applicable rights of indemnification and exculpation contemplated by this Section 7.05 and pursuant to the terms of the articles of incorporation or bylaws of AIR as in effect at or prior to the Effective Time shall not be impaired by any modification of such terms in any amendment or restatement of such articles of incorporation or bylaws following the Effective Time.

(b) For the three-year period commencing immediately after the Effective Time, AIR shall maintain in effect a directors’ and officers’ liability insurance with an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of the date hereof covering acts or omissions occurring at or prior to the Effective Time with respect to those individuals who are currently (and any additional individuals who prior to the Effective Time become) covered by AIR’s directors’ and officers’ liability insurance policies on terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies in effect on the date of this Agreement. AIR shall be permitted, prior to the Effective Time, to obtain and fully pay the premium, subject to the maximum annual premium referred to in the first proviso to this Section 7.05(b), for the extension of (i) the directors’ and officers’ liability coverage of AIR’s existing directors’ and officers’ insurance policies and (ii) AIR’s existing fiduciary liability insurance policies, in each case, for a claims reporting or discovery period of three years from and after the Effective Time that shall be from an insurance carrier with the same or better credit rating as AIR’s insurance carrier as of the date hereof with respect to directors’ and officers’ liability insurance and fiduciary liability insurance (collectively, “D&O Insurance”) with terms, conditions, retentions and limits of liability that are at least as favorable as AIR’s existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement, the Merger or the other Transactions). Notwithstanding anything to the contrary contained herein, in no event shall Tenax or AIR after the Effective Time be required to expend for any policies contemplated by this clause (b) an annual premium amount in excess of 300% of the annual premiums currently paid by AIR for such insurance; provided further that if the annual premiums of such insurance coverage exceed such amount, after the Effective Time, AIR shall obtain a policy with the greatest coverage available for a cost not exceeding such amount. If such prepaid D&O Insurance has been obtained by AIR prior to the Effective Time, it shall be deemed to satisfy all obligations to obtain insurance pursuant to this Section 7.05(b), and AIR shall use its reasonable best efforts to cause such D&O Insurance to be maintained in full force and effect, for its full term, and to honor all of its obligations thereunder.

(c) In the event AIR or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of AIR shall assume the obligations set forth in this Section 7.05.

Section 7.06 Notification of Certain Matters.

(a) AIR shall give prompt notice to Tenax, and Tenax shall give prompt notice to AIR, of (i) the occurrence, or non-occurrence, of any change, event, fact or development which would reasonably be expected to cause any of their respective representations or warranties contained in this Agreement to become untrue or inaccurate such that the conditions set forth in Section 8.02(a) or Section 8.03(a) would not be satisfied and (ii) any failure of AIR, Tenax or Merger Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement such that the conditions set forth in Section 8.02(b) or Section 8.03(b) would not be satisfied; provided, however, that the delivery of any notice pursuant to this Section 7.06 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

(b) AIR shall give prompt notice to Tenax, and Tenax shall give prompt notice to AIR, of (i) any notice or other communication from any Governmental Authority in connection with the Transactions or from any Person alleging that the consent of such Person is or may be required in connection with the Transactions and (ii) any Action commenced or, to its knowledge, threatened in writing relating to or involving or otherwise affecting it or any of its Subsidiaries which, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Article IV or Article V, as applicable, or which relates to the consummation of the Transactions.

Section 7.07 Reasonable Best Efforts; Further Action.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the Transactions, including using its reasonable best efforts to accomplish the following: (i) the satisfaction of the conditions precedent set forth in Article VIII; (ii) the obtaining of all necessary actions or nonactions and consents from, and the giving of any necessary notices to, Governmental Authorities and the making of all necessary registrations, declarations and filings (including filings that are required or advisable under the HSR Act, and other registrations, declarations and filings with, or notices to, Governmental Authorities, that may be required under the HSR Act or are required or advisable under other applicable antitrust, competition or pre-merger notification Laws of any jurisdiction (collectively, “Antitrust Laws”), if any); (iii) the taking of all reasonable steps to provide any supplemental information requested by any Governmental Authority, including participating in meetings with officials of such entity in the course of its review of this Agreement or the Transactions, including the Merger; (iv) the taking of all reasonable steps as may be necessary to avoid any Action by any Governmental Authority or third party that would otherwise have the effect of materially delaying or preventing the consummation of the Merger; and (v) the defending or contesting of any Actions challenging this Agreement or the consummation of the Merger, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed. In connection with and without limiting the generality of the foregoing, each of AIR and the AIR Board shall, if any state takeover statute or similar statute or regulation is or becomes applicable to this Agreement or any of the Transactions, take all actions necessary to ensure that the Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on this Agreement and the Transactions, including the Merger, contemplated by this Agreement. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Tenax or its Affiliates (including, after the Effective Time, AIR and its Subsidiaries) be required to agree to or accept (A) any prohibition of or limitation on its or their ownership, or any limitation that would affect its or their operation, of any portion of their respective businesses or assets, including after giving effect to the Transactions; (B) any commitment, undertaking or Order to divest, hold separate or otherwise dispose of any portion of its or their respective businesses or assets, including after giving effect to the Transactions; (C) any limitation on the ability of the Tenax Members to acquire or hold or exercise full rights of ownership of any capital stock of AIR or its Subsidiaries, including after giving effect to the Transactions; or (D) any other limitation on its or their ability to, or the manner in which they, operate, conduct or control their respective businesses or operations, including after giving effect to the Transactions (any such action or limitation described in clauses (A) through (D), a “Restriction”). Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Tenax or any of its Affiliates be obligated to (x) litigate or participate in the litigation of any administrative Action before the United States Federal Trade Commission in connection with obtaining the expiration of the waiting period under the HSR Act or any consent from a Governmental Authority under Antitrust Laws in the United States in connection with the transactions contemplated by this Agreement or (y) challenge the decision of any Governmental Authority under Antitrust Laws in any jurisdiction other than the United States.

(b) Notwithstanding anything to the contrary herein, Tenax shall determine the strategy to be pursued for obtaining and lead the effort to obtain all necessary actions or nonactions and consents from Governmental Authorities in connection with the Transactions contemplated by this Agreement, and AIR shall take all reasonable actions to support Tenax in connection therewith. Each of Tenax and AIR shall (i) reasonably cooperate with each other in connection with any filing or submission with any Governmental Authorities in connection with the Transactions and any consents from any Governmental Authority in connection therewith and any investigation or other inquiry related thereto and in connection with resolving any such investigation or inquiry with respect to any such filing or the Merger; (ii) not extend any waiting or suspension period under any applicable Antitrust Laws or enter into any agreement with any Governmental Authority not to consummate the Merger, except with the prior written consent of the other party (such consent not to be unreasonably withheld, conditioned or delayed); (iii) respond as promptly as practicable to any applicable inquiries or requests received from any Governmental Authority for additional information or documentation; (iv) promptly make any applicable further filings or information submissions pursuant thereto that may be necessary or advisable; and (v) promptly make any requisite filings or submissions required or advisable under any applicable Antitrust Laws. Each of Tenax and AIR shall (A) promptly notify the other party of any written or oral communication to that party or its Subsidiaries or Representatives from any Governmental Authority regarding the parties’ collaborative efforts to obtain consents to the Merger under Antitrust Laws; (B) subject to applicable Law and to the extent reasonably practicable, permit the other party to review and comment on any substantive written communication regarding such efforts prior to providing such communication to any Governmental Authority; and (C) to the extent reasonably practicable, not agree to participate, or permit its Subsidiaries or Representatives to participate, in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning consents to the Merger under Antitrust Laws unless it consults with the other party in advance and, to the extent permitted by such Governmental Authority and reasonably practicable, gives the other party the opportunity to attend and participate. Without limiting the foregoing, neither party shall make any filings, submissions or substantive written communications to any Governmental Authority to obtain consents to the Merger under Antitrust Laws without first providing a written copy of such filing, submission or communication to the other party (or as appropriate to such party’s outside counsel) and allowing the other party a reasonable opportunity to provide comments on such filing, submission or communication prior to submission. Tenax and AIR covenant and agree to incorporate all reasonable comments of the other party (or as appropriate such party’s outside counsel) with respect to such filings, submissions and communications prior to delivery of the same to any Governmental Authority.

(e) The Tender Offer shall expire at midnight, New York City time (i.e., one minute after 11:59 p.m., New York City time), on the date that is 20 Business Days (calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) following the commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Tender Offer (such expiration date and time of the Tender Offer, the “Expiration Time”). The Tender Offer may not be terminated prior to its scheduled Expiration Time, unless this Agreement is terminated in accordance with Article IX.

Section 9.03 Fees and Expenses.

(a) In the event that:

(i) AIR terminates this Agreement pursuant to Section 9.01(d)(iii) to accept a Superior Proposal;

(ii) Tenax terminates this Agreement pursuant to Section 9.01(c)(ii) following a Change in the AIR Recommendation; or

(iii) (A) (I) either AIR or Tenax terminates this Agreement pursuant to Section 9.01(b)(i) (but only if the AIR Stockholders Meeting has been held prior to such termination) or Section 9.01(b)(iii) or (II) Tenax terminates this Agreement pursuant to Section 9.01(c)(i), (B) prior to the termination of this Agreement, a Competing AIR Proposal shall have been publicly announced or shall have become publicly known and (C) on or prior to the date that is 12 months after the date of such termination, AIR enters into a Competing AIR Transaction Agreement in respect of such Competing AIR Proposal and the transaction contemplated thereby is consummated,

then AIR shall pay to Tenax a fee equal to $1,250,000 (the “AIR Termination Fee”) by wire transfer of immediately available funds to an account designated by Tenax (x) in the event of clause (i), upon such termination; (y) in the event of clause (ii), within five Business Days of such termination; and (z) in the event of clause (iii), within five Business Days of the closing of the Competing AIR Proposal transaction. In no event shall AIR be required to pay the AIR Termination Fee on more than one occasion.

(b) In the event that AIR shall terminate this Agreement pursuant to Section 9.01(d)(i) or Section 9.01(d)(ii), or Tenax shall terminate this Agreement pursuant to Section 9.01(b)(iii) and at such time AIR could have terminated this Agreement pursuant to Section 9.01(d)(i) or Section 9.01(d)(ii), then Tenax shall pay to AIR a fee equal to $1,250,000 (the “Tenax Termination Fee”) by wire transfer of immediately available funds to an account designated by AIR within five Business Days following such termination. In no event shall Tenax be required to pay the Tenax Termination Fee on more than one occasion.

(c) In the event that either AIR or Tenax terminates this Agreement pursuant to Section 9.01(b)(i) (but only if the AIR Stockholders Meeting has been held prior to such termination), then, in addition to any other payments that may be required to be made pursuant to this Section 9.03, AIR shall reimburse Tenax for Tenax’s reasonable and documented out-of-pocket costs and expenses incurred in connection with the execution of this Agreement and the consummation of the Transactions, up to $500,000, by wire transfer of immediately available funds to an account designated by Tenax or by transfer of AIR Common Stock of equal value within five Business Days following such termination.

(d) In the event that AIR shall terminate this Agreement pursuant to Section 9.01(d)(iv), then, in addition to any other payments that may be required to be made pursuant to this Section 9.03, Tenax shall reimburse AIR for AIR’s reasonable and documented out-of-pocket costs and expenses incurred in connection with the execution of this Agreement and the consummation of the Transactions, up to $500,000, by wire transfer of immediately available funds to an account designated by AIR within five Business Days following such termination.

(e) All Expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such Expenses, whether or not the Merger or any other Transaction is consummated, except Expenses constituting the out-of-pocket cost of (i) filing fees, printing and mailing of the Proxy Statement (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel) and (ii) the filing fees for the premerger notification and report forms under the HSR Act (excluding, for the avoidance of doubt, the fees and expenses of AIR’s legal counsel), which, in each case, shall be paid by Tenax.

(f) The parties hereto acknowledge and agree that the agreements contained in Section 9.03(a) are an integral part of the Transactions, and that, without these agreements, the parties hereto would not enter into this Agreement; accordingly, if AIR fails promptly to pay the AIR Termination Fee, and, in order to obtain such payment, Tenax commences a suit that results in a judgment against AIR for the AIR Termination Fee, AIR shall pay to Tenax its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, up to $500,000, together with interest on the amount of the AIR Termination Fee from the date such payment was required to be made until the date of payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made. Each party further acknowledges that the AIR Termination Fee is not a penalty, but rather is a reasonable amount that will compensate the receiving party in the circumstances in which such payment is payable for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions contemplated hereby, which amounts would otherwise be impossible to calculate with precision.

(g) The parties hereto acknowledge and agree that the agreements contained in Section 9.03(b) are an integral part of the Transactions, and that, without these agreements, the parties hereto would not enter into this Agreement; accordingly, if Tenax fails promptly to pay the Tenax Termination Fee, and, in order to obtain such payment, AIR commences a suit that results in a judgment against Tenax for the Tenax Termination Fee, Tenax shall pay to AIR its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, up to $500,000, together with interest on the amount of the Tenax Termination Fee from the date such payment was required to be made until the date of payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made. Each party further acknowledges that the Tenax Termination Fee is not a penalty, but rather is a reasonable amount that will compensate the receiving party in the circumstances in which such payment is payable for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions contemplated hereby, which amounts would otherwise be impossible to calculate with precision.

(h) In the event the AIR Termination Fee is required to be paid and is paid to Tenax pursuant to Section 9.03(a), such payment of the AIR Termination Fee shall constitute liquidated damages and be the sole and exclusive monetary remedy of Tenax and its Subsidiaries and Tenax’s and its Subsidiaries’ respective current, former or future equityholders, employees, directors, officers, Affiliates or Representatives (collectively, the “Tenax Related Parties”) against AIR and Merger Sub and their respective current, former or future equityholders, employees, directors, officers, Affiliates or Representatives (collectively, the “AIR Related Parties”) for all losses, damages, costs or expenses in respect of this Agreement (or the termination thereof) or the Transactions (or the failure of such transactions to occur for any reason or for no reason) or any breach (whether willful, intentional, unilateral or otherwise) of any covenant or agreement or otherwise in respect of this Agreement or any oral representation made or alleged to be made in connection herewith, and upon payment of the AIR Termination Fee, none of the AIR Related Parties shall have any further monetary liability or obligation relating to or arising out of this Agreement or the Transactions, and none of Tenax, its Subsidiaries or any other Tenax Related Party shall seek to recover any other monetary damages.

(i) In the event the Tenax Termination Fee is required to be paid and is paid to AIR pursuant to Section 9.03(b), such payment of the Tenax Termination Fee shall constitute liquidated damages and be the sole and exclusive monetary remedy of the AIR Related Parties against the Tenax Related Parties for all losses, damages, costs or expenses in respect of this Agreement (or the termination thereof) or the Transactions (or the failure of such transactions to occur for any reason or for no reason) or any breach (whether willful, intentional, unilateral or otherwise) of any covenant or agreement or otherwise in respect of this Agreement or any oral representation made or alleged to be made in connection herewith, and upon payment of the Tenax Termination Fee, none of the Tenax Related Parties shall have any further monetary liability or obligation relating to or arising out of this Agreement or the Transactions, and none of AIR, its Subsidiaries or any other AIR Related Party shall seek to recover any other monetary damages.

Section 9.04 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of the Tenax Board, the AIR Board and the Board of Directors of Merger Sub at any time prior to the Effective Time; provided, however, that, after the AIR Stockholder Approvals have been obtained, no amendment may be made that under applicable Law or in accordance with the rules of any relevant stock exchange requires further approval by the stockholders of AIR without such approval having been obtained. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

Section 9.05 Waiver. At any time prior to the Effective Time, any party hereto may (a) extend the time for the performance of any obligation or other act of any other party hereto, (b) to the extent permitted by applicable Law, waive any breach of or inaccuracy in the representations and warranties of any other party contained in this Agreement or in any document delivered pursuant hereto and (c) to the extent permitted by applicable Law, waive compliance with any agreement of any other party or any condition to its own obligations contained in this Agreement. No extension or waiver by AIR shall require the approval of the stockholders of AIR, unless required by applicable Law. Notwithstanding the foregoing, no failure or delay by Tenax or AIR or Merger Sub in exercising any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or future exercise of any other right hereunder. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby.

Section 9.06 Procedure for Termination or Amendment. A termination of this Agreement pursuant to Section 9.01 or an amendment of this Agreement pursuant to Section 9.04 shall, in order to be effective, require, in the case of Tenax or AIR, action by the Tenax Board or the AIR Board or, with respect to any amendment of this Agreement pursuant to Section 9.04, the duly authorized committee of the Tenax Board or the AIR Board to the extent permitted by applicable Law.

Section 10.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by virtue of any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

Section 10.07 Specific Performance. The parties hereto agree that the parties hereto would be irreparably damaged if any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. Accordingly, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of the terms of this Agreement, in addition to any other remedy at law or in equity. The parties further agree that no party to this Agreement shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any such legal or equitable relief, and each party waives any objection to the imposition of such relief or any right it might have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Section 10.08 Governing Law.
