Article
2

EXCHANGE

 

Section
2.01         Exchanges. (a) Permissible Exchanges.
(i) The Company shall establish one or more dates in each fiscal year as a date on which the Members (other than the Highbridge
Members) shall be permitted to elect to Exchange, provided that the Company may postpone any such date one or more times and (ii)
on the date that is six months after the date of the final prospectus filed with the Securities and Exchange Commission relating
to the IPO, the Company shall automatically Exchange all Common Units held by the Highbridge Members (each such date an “Exchange
Date”). Except as to the Highbridge Members, the Company shall give notice to each Member of the establishment of an
Exchange Date at least 75 and no more than 90 Business Days prior to the Exchange Date. Except as to the Highbridge Members, the
Company may permit, in writing or orally, one or more Members to submit an Exchange Request on such other dates, such permission
to be granted, withheld or granted on such terms and conditions as determined by the Company in its sole discretion. Except
as to the automatic Exchange by the Highbridge Members where no Exchange Request shall be required, upon the terms and subject
to the conditions of this Article 2, each Member may, on an Exchange Date, elect to Exchange up to 100% of the Member’s Common
Units (together with the corresponding number of Class B Shares, to the extent that such Member holds such Class B Shares) by delivering
an Exchange Request to the Company with a copy to OTG EXP at least 60 days prior to the Exchange Date. If the Company does not
elect on or before the close of business on the fifth Business Day after the Company’s receipt of an Exchange Request to
exchange all of the Common Units set forth in such Exchange Request from such Member (other than Highbridge Members) for the Cash
Amount, then the portion of the Common Units set forth in the Exchange Request not being exchanged for the Cash Amount shall be
exchanged for Class A Shares based on the Exchange Rate. Upon the automatic Exchange of all of the Common Units held by the Highbridge
Members, such Common Units shall be exchanged for Class A Shares based on the Exchange Rate.

 

    	6

    	 

    

 

(i)      Each
Exchange Request shall set forth the number of Common Units (together with the corresponding number of Class B Shares, to
the extent that such Member holds such Class B Shares) such Member wishes to Exchange at the applicable Closing.

 

(ii)     Each
Member shall represent in the Exchange Request that such Member owns or will own the Common Units and Class B Shares (to the
extent that such Member holds such Class B Shares) to be delivered at the applicable Closing pursuant to Section 2.01(d)(i)
and Section 2.01(d)(ii), free and clear of all Liens, except as set forth therein and other than transfer restrictions imposed
by or under applicable securities laws and this Agreement and the Operating Agreement, and, if there are any Liens identified in
the Exchange Request, such Member shall covenant that such Member will deliver at the applicable Closing evidence reasonably satisfactory
to the Company that all such Liens (other than transfer restrictions imposed by or under applicable securities laws and this Agreement
and the Operating Agreement) have been released.

 

(iii)    Upon
delivery to the Company, no Exchange Request may be revoked prior to the scheduled Closing of the applicable Exchange unless the
Member that has delivered such Exchange Request reimburses all out-of-pocket costs incurred by OTG EXP or the Company with respect
to such requested Exchange.

 

(iv)    No
Exchange pursuant to an Exchange Request shall be permitted (and, if attempted, shall be void ab initio) if, in the good faith
determination of the Company, such Exchange would pose a material risk that the Company would be a “publicly traded partnership”
as defined in Section 7704 of the Code; provided that an Exchange will not be prohibited on this basis so long as the Company
reasonably determines (in its sole discretion) that it continues to satisfy the “private placements” safe harbor pursuant
to Section 1.7704-1 of the Treasury Regulations promulgated under Section 7704 of the Code.

 

    	7

    	 

    

 

(v)     Each
Exchange pursuant to this Section 2.01(a) shall be at the Exchange Rate in effect at the applicable Closing.

 

(vi)    Notwithstanding
anything herein to the contrary, with respect to any Exchange pursuant to an Exchange Request:

 

(A)    Without
the consent of the Company, no Member may Exchange less than 50,000 Common Units (as adjusted for any unit split, unit distribution,
reverse unit split, reclassification or similar event, in each case with such adjustment being determined by the Company) or, if
such Member holds less than 50,000 Common Units (as adjusted for any unit split, unit distribution, reverse unit split, reclassification
or similar event, in each case with such adjustment being determined by the Company), all of the Common Units held by such Member.

 

(B)    The
consummation of such Exchange shall be subject to the expiration or termination of the applicable waiting period, if any, under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

 

(b)          Closing.
(i) If an Exchange Request has been delivered pursuant to Section 2.01(a)(i), then (subject to Section 2.01(c))
the Closing of such Exchange shall occur on the applicable Exchange Date. The Closing of the automatic Exchange of all of the Common
Units held by the Highbridge Members pursuant to Section 2.01(a)(ii) shall (subject to Section 2.01(c)) occur on the
applicable Exchange Date.

 

(ii)      If
OTG EXP enters into an agreement to consummate a Business Combination Transaction, OTG EXP shall give each Member at least five Business
Days’ notice of the closing thereof and, upon the written request of a Member, OTG EXP shall cause such agreement to (and
shall not enter into any such agreement unless it does) provide that such Member shall be entitled to Exchange its Common Units
(together with the corresponding number of Class B Shares, to the extent that such Member holds such Class B Shares) immediately
prior to the closing of the Business Combination Transaction in order for such Member to be able to receive the amount and type
of consideration payable pursuant to such Business Combination Transaction to holders of Class A Shares. If any Person commences
a tender offer or exchange offer for any of the outstanding shares of OTG EXP’s stock, upon the written request of a Member,
OTG EXP shall entitle such Member, at the request of such Member, to Exchange its Common Units (together with the corresponding
number of Class B Shares, to the extent that such Member holds such Class B Shares) immediately prior to and contingent upon
the consummation of such tender offer or exchange offer in order for such Member to participate in such tender offer or exchange
offer. Notwithstanding anything to the contrary in the foregoing, in the event that board of directors of OTG EXP approves a Business
Combination Transaction and determines in good faith that such Business Combination Transaction involves a bona fide third party
and is not for the primary purpose of causing an Exchange hereunder, then upon at least five Business Days’ notice, the mandatory
Exchange of all outstanding Common Units (together with the corresponding number of Class B Shares, to the extent that such
Member holds such Class B Shares) shall occur in accordance with the following sentence. The Closing for any Exchange in which
Class A Shares are delivered occurring pursuant to this Section 2.01(b)(ii) shall occur immediately prior to, but remain
subject to the consummation immediately after of, the Business Combination Transaction, tender offer or exchange offer, as applicable,
and such Exchange shall be null and void if such Business Combination Transaction, tender offer or exchange offer, as applicable,
shall fail to be consummated.

 

    	8

    	 

    

 

(iii)     Upon
receiving notice of an Exchange Request under Section 2.01(a)(i), the Company may elect to cause OTG EXP to effect the Exchange
under Section 2.01(d) and deliver to the Exchanging Member, at OTG EXP’s option, the number of Class A Shares and/or
the Cash Amount that such Member is entitled to receive in the Exchange. In all other cases, the Company shall effect the Exchange
and, at the time of the Closing of any such Exchange,(i) OTG EXP shall contribute to the Company (A) the number of Class A
Shares that such Member is entitled to receive in the Exchange, or (B) the Cash Amount, as applicable, and (ii) the Company shall
issue to OTG EXP a number of Common Units equal to the number of Common Units being exchanged by the Exchanging Member.
Notwithstanding any other provision of this Agreement to the contrary, in the event that OTG EXP elects to deliver to the Exchanging
Member the Cash Amount in the case of a Member other than a Highbridge Member, OTG EXP shall only be obligated to contribute to
the Company an amount in respect of such Cash Amount equal to the net proceeds (after deduction of any underwriters’ discounts
or commissions and brokers’ fees or commissions) from the sale by OTG EXP of a number of shares of Class A Common Stock equal
to the number of Common Units to be redeemed provided that the Company’s Capital Account, as defined under the Operating
Agreement, shall be increased by an amount equal to any account underwriters’ discounts or commissions and brokers’
fees or commissions relating to such sale of shares.

 

(iv)  Upon
the occurrence of a Closing, (A) all rights of the Exchanging Member as holder of the Common Units (and corresponding number
of Class B Shares, to the extent that such Member holds such Class B Shares) being Exchanged shall terminate, (B) any
Class B Shares delivered at the Closing shall be automatically cancelled on the books and records of OTG EXP and shall no
longer be deemed to be issued and outstanding capital stock of OTG EXP, (C) the Common Units delivered at the Closing to the
Company shall automatically be cancelled on the books and records of the Company and shall no longer be deemed to be issued and
outstanding membership interests of the Company, and (D) such Exchanging Member, or such other Person in whose name such Exchanging
Member has requested the shares be registered, shall be treated for all purposes as the holder of any Class A Shares delivered
at the Closing.

 

(v)   The
Class A Shares to be received in the Exchange shall be registered in such names and in such denominations as the Exchanging
Member shall request in writing not later than one Business Day prior to Closing.

 

    	9

    	 

    

 

(c)          Closing
Conditions. (i) The obligation of any of the parties to consummate an Exchange pursuant to this Section 2.01 shall
be subject to the condition that there shall be no injunction, restraining order or decree of any nature of any Governmental Entity
that is then in effect that restrains or prohibits the Exchange.

 

(ii)       The
obligation of the Company and OTG EXP to consummate an Exchange pursuant to this Section 2.01 shall be subject to (A) the
delivery by the Exchanging Member (other than a Highbridge Member) of the items specified in clauses (i), (ii), (iii), (iv) and
(vi) of Section 2.01(d) and (B) the good faith determination by OTG EXP that such Exchange would not be prohibited
by applicable law or regulation and would not violate any contract, commitment, agreement, instrument, arrangement, understanding,
obligation or undertaking to which the Company or OTG EXP is subject.

 

(iii)      Upon
the automatic Exchange by the Highbridge Members, such Highbridge Members shall be deemed to represent and warrant that no Liens
exist on the Common Units held by such Highbridge Members (other than transfer restrictions imposed by or under applicable securities
laws, the Operating Agreement and this Agreement), or that any such Liens have been released.

 

(d)          Closing
Deliveries. At or prior to each Closing, with respect to each Member for which an Exchange is contemplated for such Closing:

 

(i)      except
as to the automatic Exchange by the Highbridge Members, to the extent that such Member’s Common Units are certificated, such
Member shall deliver to the Company or OTG EXP, as applicable, one or more certificates representing the number of Common Units
specified in the applicable Exchange Request (or an affidavit of loss in lieu thereof in customary form, without any requirement
to post a bond or furnish any other security), accompanied by security transfer powers, in form reasonably satisfactory to the
Company or OTG EXP, as applicable, duly executed in blank by such Member or such Member’s duly authorized attorney, to be
Exchanged based on the Exchange Rate in effect at the applicable Closing;

 

(ii)     except
as to the automatic Exchange by the Highbridge Members, to the extent such Member holds Class B Shares and the Member’s Class B
Shares are certificated, such Member shall deliver to the Company or OTG EXP, as applicable, one or more certificates representing
the number of Class B Shares specified in the applicable Exchange Request (or an affidavit of loss in lieu thereof in customary
form, without any requirement to post a bond or furnish any other security), accompanied by security transfer powers, in form reasonably
satisfactory to the Company or OTG EXP, as applicable, duly executed in blank by such Member or such Member’s duly authorized
attorney;

 

(iii)    except
as to the automatic Exchange by the Highbridge Members, such Member shall represent in writing, and at the Company or OTG EXP’s
request deliver confirmatory evidence reasonably satisfactory to the Company or OTG EXP, as applicable, that no Liens exist on
the Common Units and Class B Shares delivered pursuant to Sections 2.01(d)(i) and 2.01(d)(ii) (other than transfer restrictions
imposed by or under applicable securities laws, the Operating Agreement and this Agreement), or that any such Liens have been released;

 

    	10

    	 

    

 

(iv)    if
such Member delivers to the Company or OTG EXP, pursuant to Section 2.01(d)(i) or 2.01(d)(ii), a certificate representing
a number of Common Units or Class B Shares that is greater than the number of Common Units or Class B Shares specified
in the applicable Exchange Request, the Company or OTG EXP will deliver to such Member certificates representing the excess Common
Units or Class B Shares, as applicable, within a reasonable period after Closing;

 

(v)     unless
the Company has elected to exchange such Member’s Common Units for the Cash Amount, the Company or OTG EXP, as applicable,
shall deliver or cause to be delivered to such Member the number of Class A Shares that such Member is entitled to receive
in the Exchange, registered in such names and such denominations as such Member requested pursuant to Section 2.01(b)(iv);
and

 

(vi)    except
as to the automatic Exchange by the Highbridge Members, if requested by the Company or OTG EXP, such Member shall deliver an opinion
of counsel for the Member reasonably satisfactory to the Company or OTG EXP, as applicable, to the effect that the proposed Exchange
will not cause the Company or OTG EXP to violate any federal or state securities laws or regulations applicable to the Exchange
or the issuance and sale of Class A Shares to the Member pursuant to this Agreement.

 

Section
2.02         Adjustment. On the date hereof, the Exchange Rate
shall be 1 for 1. The Exchange Rate shall be adjusted accordingly if there is: (i) any subdivision (by any unit or stock split,
unit or stock distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit or
stock split, reclassification, reorganization, recapitalization or otherwise) of the Common Units or Class B Shares or any similar
event, in each case that is not accompanied by an identical subdivision or combination of the Class A Shares; or (ii) any
subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise)
or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Shares
or any similar event, in each case that is not accompanied by an identical subdivision or combination of the Common Units and Class
B Shares. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A
Shares are converted or changed into another security, securities or other property, then upon any subsequent Exchange, an Exchanging
Member shall be entitled to receive the amount of such security, securities or other property that such Exchanging Member would
have received if such Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization
or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or
dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification,
recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification,
reorganization, recapitalization or other similar transaction. For the avoidance of doubt, if there is any reclassification, reorganization,
recapitalization or other similar transaction in which the Class A Shares are converted or changed into another security,
securities or other property, this Section 2.02 shall continue to be applicable, mutatis mutandis, with respect to
such security or other property.

 

    	11

    	 

    

 

Section
2.03         Expiration. In the event that the Company is dissolved,
liquidated or wound up pursuant to the Operating Agreement or otherwise, any Exchange Right shall expire upon final distribution
of the assets of the Company pursuant to the terms and conditions of the Operating Agreement.

 

Section
2.04         Reservation of Class A Shares; Listing. OTG EXP
shall at all times reserve and keep available out of its authorized but unissued Class A Shares, solely for the purpose of
issuance upon an Exchange, the maximum number of Class A Shares as shall be issuable upon Exchange of all outstanding Common
Units and Class B Shares; provided that nothing contained herein shall be construed to preclude OTG EXP from satisfying its obligations
in respect of any such Exchange by delivery of purchased Class A Shares (which may or may not be held in the treasury of OTG
EXP). If any Class A Shares require registration with or approval of any Governmental Entity under any federal or state law
before such Class A Shares may be issued upon an Exchange, OTG EXP shall use reasonable efforts to cause the exchange of such
Class A Shares to be duly registered or approved, as the case may be. OTG EXP shall list and use its reasonable efforts to
maintain the listing of the Class A Shares required to be delivered upon any such Exchange prior to such delivery upon the
national securities exchange upon which the outstanding Class A Shares are listed at the time of such Exchange (it being understood
that any such shares may be subject to transfer restrictions under applicable securities laws). OTG EXP covenants that all Class A
Shares issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable.

 

Section
2.05         Recapitalization. This Agreement shall apply to the
Common Units held by the Members and their Permitted Transferees as of the date hereof, as well as any Common Units hereafter acquired
by a Member and its Permitted Transferees. This Agreement shall apply to, mutatis mutandis, and all references to “Common
Units” shall be deemed to include, any security, securities or other property of the Company that may be issued in respect
of, in exchange for or in substitution of Common Units, by reason of any distribution or dividend, split, reverse split, combination,
reclassification, reorganization, recapitalization, merger, exchange (other than an Exchange) or other transaction.

 

Section
2.06         Removal of Impediments to Exchange. The Company
and OTG EXP shall use reasonable best efforts to remove any impediment that in the good faith judgment of the Company and OTG EXP
would cause any Exchange to be prohibited by applicable law or regulation or that would cause any Exchange to violate any contract,
commitment, agreement, instrument, arrangement, understanding, obligation or undertaking to which the Company or OTG EXP is subject
and if the automatic Exchange by any Highbridge Member is so prohibited, such Exchange by the Highbridge Members shall automatically
occur within 3 Business Days after such removal.

each Member understands and agrees that, unless exchanged pursuant to an effective registration statement under the Securities
Act, the Restricted Class A Shares are restricted securities under the Securities Act and the rules and regulations promulgated
thereunder. Each Member agrees that it shall not Transfer any Restricted Class A Shares (or solicit any offers in respect
of any Transfer of any Restricted Class A Shares), except in compliance with the Securities Act, any other applicable securities

of counsel to the transfer agent.

THIS SECURITY HAS NOT BEEN REGISTERED UNDER
THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR ANY NON-U.S. OR STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD, PLEDGED OR
OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE THEREWITH.

 

(a)         If
any Restricted Class A Share is eligible to be sold pursuant to Rule 144(b)(1) under the Securities Act (or any successor
provision), upon the written request of the holder thereof, accompanied (if OTG EXP shall so request) by an opinion of counsel
reasonably acceptable to OTG EXP, it shall issue to such holder a new certificate evidencing such Restricted Class A Share
without the legend required by Section 3.02(a) endorsed thereon.

 

Section

ARTICLE II.

DETERMINATION OF CUMULATIVE REALIZED TAX BENEFIT

 

2.1.           
Basis Adjustments. The Parties acknowledge and agree that (A) each Exchange shall be treated as a direct purchase
of Units by the Corporation from the applicable Beneficiary pursuant to Section 707(a)(2)(B) of the Code and (B) each
Exchange will give rise to an increase in the Corporation’s share of the Non-Adjusted Tax Basis in each Reference Asset and
an adjustment to the basis of such Reference Asset determined in accordance with Treasury Regulations Section 1.743-1, collectively,
in an amount equal to the sum of (x) the Market Value of Class A Common Stock and/or the cash transferred to a Beneficiary
pursuant to the Exchange, (y) the amount of payments made pursuant to this Agreement with respect to such Exchange and (z) the
amount of liabilities allocated to the Units acquired pursuant to such Exchange (a “Basis Adjustment”). The
Basis Adjustment with respect to a Reference Asset (or applicable portions thereof, where the Basis Adjustment exceeds the basis
adjustment under Section 732 or 743(b) of the Code) shall be deemed to be recovered over the period under which it would customarily
be recovered under applicable Law. Basis Adjustments reflecting the Corporation’s increased share of the Non-Adjusted Tax
Basis in a Reference Asset shall be determined as of the Exchange Date and shall not be adjusted as a result of future changes
to the Corporation’s ownership percentage in OTG Management. For the avoidance of doubt, payments made under this Agreement
shall not be treated as resulting in a Basis Adjustment to the extent such payments are treated as Imputed Interest or are Actual
Interest Amounts.

 

2.2.           
OTG Section 754 Election.  In its capacity as the sole managing member of OTG Management, the Corporation
will ensure that, on and after the date hereof and continuing throughout the term of this Agreement, OTG Management and each of
its direct and indirect Subsidiaries (including any successors to OTG Management and its direct and indirect Subsidiaries arising
as a result of terminations occurring pursuant to Section 708(b)(1)(B) of the Code) that is treated as a partnership
for U.S. federal income tax purposes will have in effect an election under Section 754 of the Code (and under any similar
provisions of applicable U.S. state or local law) for each Taxable Year.

 

2.3.           
Pre-IPO NOLs. The Corporation and OTG Management, on the one hand, and each former shareholder of AOTG, on the other
hand, acknowledge that the Corporation may be entitled to utilize the Pre-IPO NOLs to reduce the amount of Taxes that the Corporation
would otherwise be required to pay in the future.

 

2.4.           
Exchange Basis Schedule. Within ninety (90) calendar days after the filing of the U.S. federal income Tax Return
of the Corporation for each relevant Taxable Year, the Corporation shall deliver to each Beneficiary a schedule (the “Basis
Schedule”) that shows, in reasonable detail as necessary in order to understand the calculations performed under this
Agreement: (a) the Non-Adjusted Tax Basis of the Reference Assets as of each applicable Exchange Date; (b) the Basis
Adjustments with respect to the Reference Assets as a result of the relevant Exchanges effected in such Taxable Year, calculated solely
with respect to Exchanges by the applicable Beneficiary; (c) the period (or periods) over which the Reference Assets are amortizable
and/or depreciable; and (d) the period (or periods) over which each Basis Adjustment described in clause (b) is amortizable
and/or depreciable.  The Basis Schedule will become final and binding on the Parties pursuant to the procedures set forth
in Section 2.6(a) and may be amended by the Parties pursuant to the procedures set forth in Section 2.6(b).

 

2.5.           
Tax Benefit Schedule.

 

(a)               
Tax Benefit Schedule. Within ninety (90) calendar days after the filing of the U.S. federal income Tax Return of
the Corporation for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporation shall
provide to each Beneficiary a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit or Realized Tax
Detriment for such Taxable Year (a “Tax Benefit Schedule”) with respect to such Beneficiary.  The Tax Benefit
Schedules will become final and binding on the Parties pursuant to the procedures set forth in Section 2.6(a), and
may be amended by the Parties pursuant to the procedures set forth in Section 2.6(b).

 

(b)              
Applicable Principles.  Subject to the provisions of this Agreement, the Realized Tax Benefit or Realized Tax
Detriment for each Taxable Year is intended to measure the decrease or increase in the Actual Tax Liability of the Corporation
for such Taxable Year attributable to the Basis Adjustments, Imputed Interest and the Pre-IPO NOLs, as determined using a “with
and without” methodology described in Section 2.6(a).  Carryovers or carrybacks of the Pre-IPO NOLs and
any tax item attributable to any Basis Adjustment or Imputed Interest shall be considered to be subject to the rules of the
Code and the Treasury Regulations or the appropriate provisions of U.S. state and local tax law, as applicable, governing the use,
limitation and expiration of carryovers or carrybacks of the relevant type.  If a carryover or carryback of any tax item includes
a portion that is attributable to a Basis Adjustment or Imputed Interest (a “TRA Portion”) and another portion
that is not (a “Non-TRA Portion”), such portions shall be considered to be used in accordance with the “with
and without” methodology so that: (i) the amount of any Non-TRA Portion is deemed utilized first, followed by the amount
of any TRA Portion (with the TRA Portion being applied on a proportionate basis consistent with the provisions of Section 3.3(a));
and (ii) in the case of a carryback of a Non-TRA Portion, such carryback shall not affect the original “with and without”
calculation made in the prior Taxable Year.  The Parties agree that all Tax Benefit Payments attributable to an Exchange (other
than the Merger will be treated as subsequent upward purchase price adjustments that give rise to further Basis Adjustments for
the Corporation beginning in the Taxable Year of payment, and as a result, such additional Basis Adjustments will be incorporated
into such Taxable Year continuing for future Taxable Years until any incremental Basis Adjustment benefits with respect to a Tax
Benefit Payment equals an immaterial amount. The Parties agree that all Tax Benefit Payments Attributable to the Merger will be
treated as additional merger consideration and, accordingly, will not result in further Basis Adjustments.

2.6.           
Procedures; Amendments.

 

(a)               
Procedures.  Each time the Corporation delivers an applicable Schedule to the Beneficiaries under this Agreement,
including any Amended Schedule delivered pursuant to Section 2.6(b), but excluding any Early Termination Schedule or
amended Early Termination Schedule delivered pursuant to the procedures set forth in Section 4.2, the Corporation shall
also: (x) deliver supporting schedules and work papers, as determined by the Corporation or as reasonably requested by any
Beneficiary, that provide a reasonable level of detail regarding the data and calculations that were relevant for purposes of preparing
the Schedule; (y) deliver a Corporation Letter supporting such Schedule; and (z) allow the Beneficiaries and their advisors
to have reasonable access to the appropriate representatives, as determined by the Corporation or as reasonably requested by the
Beneficiaries, at the Corporation and the Advisory Firm in connection with a review of such Schedule.  Without limiting the
generality of the preceding sentence, the Corporation shall ensure that any Tax Benefit Schedule that is delivered to the Beneficiaries,
along with any supporting schedules and work papers, provides a reasonably detailed presentation of the calculation of the Actual
Tax Liability of the Corporation for the relevant Taxable Year (the “with” calculation) and the Hypothetical Tax Liability
of the Corporation for such Taxable Year (the “without” calculation), and identifies any material assumptions or operating
procedures or principles that were used for purposes of such calculations.  An applicable Schedule or amendment thereto shall
become final and binding on the Parties thirty (30) calendar days from the date on which the Beneficiaries first received the applicable
Schedule or amendment thereto unless: 

 

(i)                
a Beneficiary within thirty (30) calendar days after receiving the applicable Schedule or amendment thereto, provides the
Corporation with (A) written notice of a material objection to such Schedule that is made in good faith and that sets forth
in reasonable detail such Beneficiary’s material objection (an “Objection Notice”) and (B) a letter
from a Beneficiary Advisory Firm in support of such Objection Notice; or

 

(ii)              
each Beneficiary provides a written waiver of its right to deliver an Objection Notice within the time period described
in clause (i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver from all Beneficiaries
is received by the Corporation.

 

In the event that a Beneficiary timely
delivers an Objection Notice pursuant to clause (i) above, and if the Parties, for any reason, are unable to successfully
resolve the issues raised in the Objection Notice within thirty (30) calendar days after receipt by the Corporation of the Objection
Notice, the Corporation and the Beneficiary shall employ the reconciliation procedures as described in Section 7.9 of this
Agreement (the “Reconciliation Procedures”).  For the avoidance of doubt, and notwithstanding anything
to the contrary herein, the expense of preparing and obtaining the letter from a Beneficiary Advisory Firm referenced in clause
(i) above shall be borne solely by the relevant Beneficiary and the Corporation shall have no liability with respect to such
letter or any of the expenses associated with its preparation and delivery.

 

(b)              
Amended Schedule.  The applicable Schedule for any Taxable Year may be amended from time to time by the Corporation:
(i) in connection with a Determination affecting such Schedule; (ii) to correct inaccuracies in the Schedule identified
as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was originally
provided to the Beneficiary; (iii) to comply with an Expert’s determination under the Reconciliation Procedures applicable
to this Agreement; (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable
to a carryback or carryforward of a loss or other Tax item to such Taxable Year; (v) to reflect a change in the Realized Tax
Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year; or (vi) to
adjust a Basis Schedule to take into account any Tax Benefit Payments made pursuant to this Agreement (any such Schedule, an “Amended
Schedule”).

ARTICLE III.

TAX BENEFIT PAYMENTS

 

3.1.           
Payments.

 

(a)               
Timing of Payments.  Subject to Sections 3.2 and 3.3, within three (3) Business Days following
the date on which each Tax Benefit Schedule that is required to be delivered by the Corporation to the Beneficiaries pursuant to
Section 2.5(a) of this Agreement becomes final in accordance with Section 2.6(a) of this Agreement
(such date, the “Final Payment Date” in respect of any Tax Benefit Payment), the Corporation shall pay to each
relevant Beneficiary the Tax Benefit Payment as determined pursuant to Section 3.1(b).  Each such Tax Benefit
Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such Beneficiaries
or as otherwise agreed by the Corporation and such Beneficiaries.  For the avoidance of doubt, the Beneficiaries shall not
be required under any circumstances to return any portion of any Tax Benefit Payment previously paid by the Corporation to the
Beneficiaries (including any portion of any Early Termination Payment).

 

(b)              
Amount of Payments.  For purposes of this Agreement, a “Tax Benefit Payment” with respect
to any Beneficiary means an amount, not less than zero, equal to the sum of: (A) the Net Tax Benefit that is Attributable
to such Beneficiary and (B) the Actual Interest Amount. 

 

(i)                
Attributable.  A Net Tax Benefit is “Attributable” to a Beneficiary to the extent that it
is derived from any Basis Adjustment or Imputed Interest that is attributable to an Exchange undertaken by or with respect to such
Beneficiary or from any Pre-IPO NOL that is deemed attributable to such Beneficiary; provided, that, in the case of any
Net Tax Benefit Attributable to the Merger, such Net Tax Benefit shall be Attributable to each former shareholder of AOTG on a
pro rata basis in accordance with their ownership interests, as provided on Exhibit A hereto.

 

(ii)              
Net Tax Benefit.  The “Net Tax Benefit” for a Taxable Year equals the amount of the excess,
if any, of (x) 85% of the Cumulative Net Realized Tax Benefit Attributable to such Beneficiary as of the end of such Taxable
Year over (y) the aggregate amount of all Tax Benefit Payments previously made to such Beneficiary under this Section 3.1. 
For the avoidance of doubt, if the Cumulative Net Realized Tax Benefit as of the end of any Taxable Year is less than the aggregate
amount of all Tax Benefit Payments previously made to a Beneficiary, such Beneficiary shall not be required to return any portion
of any Tax Benefit Payment previously made by the Corporation to such Beneficiary.

 

(iii)            
Imputed Interest.  The principles of Sections 1272, 1274, or 483 of the Code, as applicable, and the principles
of any similar provision of U.S. state and local law, will apply to cause a portion of any Net Tax Benefit payable by the Corporation
to a Beneficiary under this Agreement to be treated as imputed interest (“Imputed Interest”).  For the
avoidance of doubt, the deduction for the amount of Imputed Interest as determined with respect to any Net Tax Benefit payable
by the Corporation to a Beneficiary shall be excluded in determining the Hypothetical Tax Liability of the Corporation for purposes
of calculating Realized Tax Benefits and Realized Tax Detriments pursuant to this Agreement.

 

(iv)            
Default Rate Interest.  In the event that the Corporation does not make timely payment of all or any portion
of a Tax Benefit Payment to a Beneficiary on or before the Final Payment Date as determined pursuant to Section 3.1(a),
the amount of “Default Rate Interest” calculated in respect of the Net Tax Benefit (including previously accrued
Imputed Interest and Extension Rate Interest) for a Taxable Year will equal interest calculated at the Default Rate from the Final
Payment Date for a Tax Benefit Payment as determined pursuant to Section 3.1(a) until the date on which the Corporation
makes such Tax Benefit Payment to such Beneficiary.  For the avoidance of doubt, the amount of any Default Rate Interest as
determined with respect to any Net Tax Benefit payable by the Corporation to a Beneficiary shall be included in the Hypothetical
Tax Liability of the Corporation for purposes of calculating Realized Tax Benefits and Realized Tax Detriments pursuant to this
Agreement.

 

    	13

    	 

    

(v)              
The Corporation and the Beneficiaries hereby acknowledge and agree that, as of the date of this Agreement and as of the
date of any future Exchange that may be subject to this Agreement, the aggregate value of the Tax Benefit Payments cannot be reasonably
ascertained for U.S. federal income or other applicable tax purposes. 

 

(c)               
Interest.  The provisions of Section 3.1(b) are intended to operate so that interest will effectively
accrue in respect of the Net Tax Benefit for any Taxable Year as follows: 

 

(i)                
first, at the applicable rate used to determine the amount of Imputed Interest under the Code (from the relevant Exchange
Date until the due date (without extensions) for filing the U.S. federal income Tax Return of the Corporation for such Taxable
Year);

 

(ii)              
second, at the Agreed Rate in respect of any Extension Rate Interest (from the due date (without extensions) for filing
the U.S. federal income Tax Return of the Corporation for such Taxable Year until the Final Payment Date for a Tax Benefit Payment
as determined pursuant to Section 3.1(a)); provided, however, that if the applicable rate used to determine
the amount of Imputed Interest under the Code is higher than the Agreed Rate, then Imputed Interest in an amount equal to such
excess shall also be deemed to accrue during such period; and

 

(iii)            
third, at the Default Rate in respect of any Default Rate Interest (from the Final Payment Date for a Tax Benefit Payment
as determined pursuant to Section 3.1(a) until the date on which the Corporation makes the relevant Tax Benefit
Payment to a Beneficiary); provided, however, that if the applicable rate used to determine the amount of Imputed
Interest under the Code is higher than the Default Rate, then Imputed Interest in an amount equal to such excess shall also be
deemed to accrue during such period.

 

3.2.           
No Duplicative Payments.  It is intended that the provisions of this Agreement will not result in the duplicative
payment of any amount (including interest) that may be required under this Agreement, and the provisions of this Agreement shall
be consistently interpreted and applied in accordance with that intent.  For purposes of this Agreement, and also for the
avoidance of doubt, no Tax Benefit Payment shall be calculated or made in respect of any estimated tax payments, including, without
limitation, any estimated U.S. federal income tax payments.

 

3.3.           
Pro-Ration of Payments as Between the Beneficiaries.

 

(a)               
Insufficient Taxable Income. Notwithstanding anything in Section 3.1(b) to the contrary, if the
aggregate potential Covered Tax benefit of the Corporation as calculated with respect to the Basis Adjustments, Imputed Interest
and Pre-IPO NOLs (in each case, without regard to the Taxable Year of origination) permitted to be utilized in a particular Taxable
Year is limited in such Taxable Year because the Corporation does not have sufficient actual taxable income, then the available
Covered Tax benefit for the Corporation shall be allocated among the Beneficiaries in proportion to the respective Tax Benefit
Payment that would have been payable if the Corporation had in fact had sufficient taxable income so that there had been no such
limitation; provided, that a Pre-IPO NOL shall be treated as expiring solely to the extent that such Pre-IPO NOL actually
expires under applicable law and such Pre-IPO NOL shall not be deemed to have expired as a result of the application of this Section
3.3(a).  As an illustration of the intended operation of this Section 3.3(a), if the Corporation had $200
of aggregate potential Covered Tax benefits with respect to the Basis Adjustments, Imputed Interest and Pre-IPO NOLs in a particular
Taxable Year (with $50 of such Covered Tax benefits being attributable to Beneficiary 1 and $150 of such Covered Tax benefits being
attributable to Beneficiary 2), such that Beneficiary 1 would have potentially been entitled to a Tax Benefit Payment of $42.50
and Beneficiary 2 would have been entitled to a Tax Benefit Payment of $127.50 if the Corporation had $200 of taxable income, and
if at the same time the Corporation only had $100 of actual taxable income in such Taxable Year, then $25 of the aggregate $100
actual Covered Tax benefit for the Corporation for such Taxable Year would be allocated to Beneficiary 1 and $75 of the aggregate
$100 actual Covered Tax benefit for the Corporation would be allocated to Beneficiary 2, such that Beneficiary 1 would receive
a Tax Benefit Payment of $21.25 and Beneficiary 2 would receive a Tax Benefit Payment of $63.75.

 

(b)              
Late Payments.  If for any reason the Corporation is not able to timely and fully satisfy its payment obligations
under this Agreement in respect of a particular Taxable Year, then Default Rate Interest will begin to accrue pursuant to Section 5.2
and the Corporation and other Parties agree that (i) the Corporation shall pay the Tax Benefit Payments due in respect of
such Taxable Year to each Beneficiary pro rata in accordance with the principles of Section 3.3(a) and
(ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments due and owing to all
Beneficiaries in respect of all prior Taxable Years have been made in full.

ARTICLE IV.

TERMINATION

 

4.1.           
Early Termination.

 

(a)               
Corporation’s Early Termination Right(b).  With the written approval of a majority of the Independent
Directors, the Corporation may completely terminate this Agreement, as and to the extent provided herein, with respect to all amounts
payable to the Beneficiaries pursuant to this Agreement by paying to the Beneficiaries the Early Termination Payment; provided
that Early Termination Payments may be made pursuant to this Section 4.1(a) only if made to all Beneficiaries
that are entitled to such a payment simultaneously; provided further, that the Corporation may withdraw any notice to execute
its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has
been paid.  Upon the Corporation’s payment of the Early Termination Payment, the Corporation shall not have any further
payment obligations under this Agreement, other than with respect to any: (i) prior Tax Benefit Payments that are due and
payable under this Agreement but that still remain unpaid as of the date of the Early Termination Notice; and (ii) current
Tax Benefit Payment due for the Taxable Year ending on or including the date of the Early Termination Notice (except to the extent
that the amount described in clause (ii) is included in the calculation of the Early Termination Payment).  If an Exchange
subsequently occurs with respect to Units for which the Corporation has exercised its termination rights under this Section 4.1(a),
the Corporation shall have no obligations under this Agreement with respect to such Exchange.

 

(b)              
Acceleration Upon Change of Control.  In the event of a Change of Control, all obligations hereunder shall be
accelerated and such obligations shall be calculated pursuant to this Article IV as if an Early Termination Notice
had been delivered on the closing date of the Change of Control and utilizing the Valuation Assumptions by substituting the phrase
“the closing date of a Change of Control” in each place where the phrase “Early Termination Effective Date”
appears.  Such obligations shall include, but not be limited to, (1) the Early Termination Payment calculated as if an
Early Termination Notice had been delivered on the closing date of the Change of Control, (2) any Tax Benefit Payments agreed
to by the Corporation and the Beneficiaries as due and payable but unpaid as of the Early Termination Notice and (3) any Tax
Benefit Payments due for any Taxable Year ending prior to, with or including the closing date of a Change of Control (except to
the extent that any amounts described in clauses (2) or (3) are included in the Early Termination Payment).  For
the avoidance of doubt, Sections 4.2 and 4.3 shall apply to a Change of Control, mutadis mutandi.

 

(c)               
Acceleration Upon Breach of Agreement.  In the event that the Corporation materially breaches any of its material
obligations under this Agreement, whether as a result of failure to make any payment when due, failure to honor any other material
obligation required hereunder, or by operation of law as a result of the rejection of this Agreement in a case commenced under
the Bankruptcy Code or otherwise, then all obligations hereunder shall be accelerated and become immediately due and payable upon
notice of acceleration from a 10% Beneficiary or as a result of a Two-Thirds Beneficiary Approval (provided that in the case of
any proceeding under the Bankruptcy Code or other insolvency statute, such acceleration shall be automatic without any such notice),
and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such notice of acceleration
(or, in the case of any proceeding under the Bankruptcy Code or other insolvency statute, on the date of such breach) and shall
include, but not be limited to: (i) the Early Termination Payment calculated as if an Early Termination Notice had been delivered
on the date of such acceleration; (ii) any prior Tax Benefit Payments that are due and payable under this Agreement but that
still remain unpaid as of the date of such acceleration; and (iii) any current Tax Benefit Payment due for the Taxable Year
ending with or including the date of such acceleration.  For purposes of this Section 4.1(c), and subject to the
following sentence, the Parties agree that the failure to make any payment due pursuant to this Agreement within thirty (30) days
of the relevant Final Payment Date shall be deemed to be a material breach of a material obligation under this Agreement for all
purposes of this Agreement, and that it will not be considered to be a material breach of a material obligation under this Agreement
to make a payment due pursuant to this Agreement within thirty (30) days of the relevant Final Payment Date.  Notwithstanding
anything in this Agreement to the contrary, it shall not be a material breach of a material obligation of this Agreement if the
Corporation fails to make any Tax Benefit Payment within thirty (30) days of the relevant Final Payment Date to the extent that
the Corporation has insufficient funds, or cannot take commercially reasonable actions to obtain sufficient funds, to make such
payment; provided that the interest provisions of Section 5.2 shall apply to such late payment (unless the Corporation
does not have sufficient funds to make such payment as a result of limitations imposed by any Senior Obligations, in which case
Section 5.2 shall apply, but the Default Rate shall be replaced by the Agreed Rate).

 

    	15

    	 

    

4.2.           
Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1
above, the Corporation shall deliver to the Beneficiaries a notice of the Corporation’s decision to exercise such right (an
“Early Termination Notice”) and a schedule (the “Early Termination Schedule”) showing in
reasonable detail the calculation of the Early Termination Payment.  The Corporation shall also (x) deliver supporting
schedules and work papers, as determined by the Corporation or as reasonably requested by a Beneficiary, that provide a reasonable
level of detail regarding the data and calculations that were relevant for purposes of preparing the Early Termination Schedule;
(y) deliver a Corporation Letter supporting such Early Termination Schedule; and (z) allow the Beneficiaries and their
advisors to have reasonable access to the appropriate representatives, as determined by the Corporation or as reasonably requested
by the Beneficiaries, at the Corporation and the Advisory Firm in connection with a review of such Early Termination Schedule. 
The Early Termination Schedule shall become final and binding on each Party thirty (30) calendar days from the first date on which
the Beneficiaries received such Early Termination Schedule unless:

 

(i) a
Beneficiary, within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Corporation with (A) notice
of a material objection to such Early Termination Schedule made in good faith and setting forth in reasonable detail such Beneficiary’s
material objection (a “Termination Objection Notice”) and (B) a letter from a Beneficiary Advisory Firm
in support of such Termination Objection Notice; or

 

(ii)each
Beneficiary provides a written waiver of such right of a Termination Objection Notice within the period described in clause (i) above,
in which case such Early Termination Schedule becomes binding on the date the waiver from all Beneficiaries is received by the
Corporation.

 

In the event that a Beneficiary
timely delivers a Termination Objection Notice pursuant to clause (i) above, and if the Parties, for any reason, are unable
to successfully resolve the issues raised in the Termination Objection Notice within thirty (30) calendar days after receipt by
the Corporation of the Termination Objection Notice, the Corporation and such Beneficiary shall employ the Reconciliation Procedures. 
For the avoidance of doubt, and notwithstanding anything to the contrary herein, the expense of preparing and obtaining the letter
from a Beneficiary Advisory Firm referenced in clause (i) above shall be borne solely by such Beneficiary and the Corporation
shall have no liability with respect to such letter or any of the expenses associated with its preparation and delivery. 
The date on which the Early Termination Schedule becomes final in accordance with this Section 4.2 shall be the “Early
Termination Reference Date.”

 

4.3.           
Payment upon Early Termination.

 

(a)               
Timing of Payment.  Within three (3) Business Days after the Early Termination Reference Date, the Corporation
shall pay to each Beneficiary an amount equal to the Early Termination Payment for such Beneficiary.  Such Early Termination
Payment shall be made by the Corporation by wire transfer of immediately available funds to a bank account or accounts designated
by the Beneficiaries or as otherwise agreed by the Corporation and the Beneficiaries.

 

(b)              
Amount of Payment.  The “Early Termination Payment” payable to a Beneficiary pursuant to
Section 4.3(a) shall equal the present value, discounted at the Early Termination Rate as determined as of the
Early Termination Reference Date, of all Tax Benefit Payments that would be required to be paid by the Corporation to such Beneficiary,
whether payable with respect to Units that were Exchanged prior to the Early Termination Effective Date or on or after the Early
Termination Effective Date, beginning from the Early Termination Effective Date and using the Valuation Assumptions.  For
the avoidance of doubt, an Early Termination Payment shall be made to each Beneficiary, regardless of whether such Beneficiary
has Exchanged all of its Units as of the Early Termination Effective Date.

 

    	16

    	 

    

ARTICLE V.

SUBORDINATION AND BREACH OF PAYMENT OBLIGATIONS

 

5.1.           
Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment or
Early Termination Payment required to be made by the Corporation to the Beneficiaries under this Agreement shall rank subordinate
and junior in right of payment to any principal, interest, or other amounts due and payable in respect of any obligations owed
in respect of secured indebtedness for borrowed money of the Corporation (“Senior Obligations”) and shall rank
pari passu in right of payment with all current or future unsecured obligations of the Corporation that are not Senior Obligations. 
To the extent that any payment under this Agreement is not permitted to be made at the time payment is due as a result of this
Section 5.1 and the terms of the agreements governing Senior Obligations, such payment obligation nevertheless shall
accrue for the benefit of the Beneficiaries and the Corporation shall make such payments at the first opportunity that such payments
are permitted to be made in accordance with the terms of the Senior Obligations.

 

5.2.           
Late Payments by the Corporation.  The amount of all or any portion of any Tax Benefit Payment or Early Termination
Payment not made to the Beneficiaries when due under the terms of this Agreement, whether as a result of Section 5.1
and the terms of the Senior Obligations or otherwise, shall be payable together with Default Rate Interest, which shall accrue
beginning on the Final Payment Date and be computed as provided in Section 3.1(b)(ix).

 

ARTICLE VI.

TAX MATTERS; CONSISTENCY; COOPERATION

 

6.1.            The
Corporation’s and OTG Management’s Tax Matters. The Corporation shall have full responsibility for, and sole
discretion over, all Tax matters concerning the Corporation and the OTG Management Group, including, without limitation, the
preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes.
Notwithstanding the foregoing, the Corporation shall notify the Beneficiaries of, and keep them reasonably informed with
respect to, the portion of any tax audit of the Corporation or OTG Management, or any of OTG Management’s Subsidiaries,
the outcome of which is reasonably expected to materially affect the Tax Benefit Payments payable to such Beneficiaries under
this Agreement, and any Beneficiary holding directly and/or indirectly at least ten percent (10%) of the outstanding Units (a
“10% Beneficiary”), shall have the right to participate in and to monitor at their own expense (but, for
the avoidance of doubt, not to control) any such portion of any such Tax audit; provided that the Corporation shall
not settle or fail to contest any issue pertaining to Covered Taxes that is reasonably expected to materially adversely
affect the Beneficiaries’ rights and obligations under this Agreement without the consent (which shall not to be
unreasonably withheld, delayed or conditioned) of each Beneficiary
that will be materially adversely affected by the settlement of or failure to contest such issue.

 

6.2.           
Consistency. All calculations and determinations made hereunder, including, without limitation, any Basis Adjustments,
the Schedules, and the determination of any Realized Tax Benefits or Realized Tax Detriments, shall be made in accordance with
the elections, methodologies or positions taken by the Corporation and OTG Management on their respective Tax Returns.  Each
Beneficiary shall prepare its Tax Returns in a manner that is consistent with the terms of this Agreement, and any related calculations
or determinations that are made hereunder, including, without limitation, the terms of Section 2.1 of this Agreement
and the Schedules provided to the Beneficiaries under this Agreement unless otherwise required by applicable Law.  In the
event that an Advisory Firm is replaced with another Advisory Firm acceptable to the Audit Committee, such replacement Advisory
Firm shall perform its services under this Agreement using procedures and methodologies consistent with the previous Advisory Firm,
unless otherwise required by law or unless the Corporation and all of the Beneficiaries agree to the use of other procedures and
methodologies.

 

6.3.           
Cooperation. Each Beneficiary shall (a) furnish to the Corporation in a timely manner such information, documents
and other materials as the Corporation may reasonably request for purposes of making any determination or computation necessary
or appropriate under this Agreement, preparing any Tax Return or contesting or defending any audit, examination or controversy
with any Taxing Authority, (b) make itself available to the Corporation and its representatives to provide explanations of documents
and materials and such other information as the Corporation or its representatives may reasonably request in connection with any
of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and the Corporation
shall reimburse any Beneficiary for any reasonable third-party costs and expenses incurred by such Beneficiary pursuant to this
Section 6.3.

 

6.4.           
Pre-IPO Tax Records. The Corporation and its advisors may rely on all Tax Returns of OTG Management that were prepared
and filed prior to the IPO and may assume that all such Tax Returns are correct, complete and accurate unless otherwise established
by a Determination.

7.2.           
Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and
the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered
to the other Parties, it being understood that all Parties need not sign the same counterpart. Delivery of an executed signature
page to this Agreement by facsimile transmission or electronic mail shall be as effective as delivery of a manually signed counterpart
of this Agreement.

 

7.3.           
Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement and supersedes all
prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. This Agreement
shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns,
and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy
of any nature whatsoever under or by reason of this Agreement.

 

7.4.           
Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Delaware,
without regard to the conflicts of laws principles thereof that would mandate the application of the laws of another jurisdiction.

 

7.5.           
Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced
by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect
so long as the economic or legal substance of the transactions contemplated hereby 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 an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated
to the greatest extent possible.

 

7.6.           
Successors; Assignment; Amendments; Waivers.

 

(a)               
Assignment.  No Beneficiary may assign, sell, pledge, or otherwise alienate or transfer any interest in this
Agreement, including the right to receive any Tax Benefit Payments under this Agreement, to any Person without the prior written
consent of the Corporation, which consent shall not be unreasonably withheld, conditioned, or delayed, and without such Person
executing and delivering a Joinder agreeing to succeed to the applicable portion of such Beneficiary’s interest in this Agreement
and to become a Party for all purposes of this Agreement (the “Joinder Requirement”); provided, however,
that to the extent any Beneficiary sells, exchanges, distributes, or otherwise transfers Units to any Person (other than the Corporation
or OTG Management) in accordance with the terms of the Exchange Agreement and/or LLC Agreement, the Beneficiaries shall have the
option to assign to the transferee of such Units its rights under this Agreement with respect to such transferred Units; provided,
further, that such transferee has satisfied the Joinder Requirement.  For the avoidance of doubt, if a Beneficiary transfers
Units in accordance with the terms of the Exchange Agreement and/or LLC Agreement but does not assign to the transferee of such
Units its rights under this Agreement with respect to such transferred Units, such Beneficiary shall continue to be entitled to
receive the Tax Benefit Payments arising in respect of a subsequent Exchange of such Units. 

 

(b)              
Amendments.  No provision of this Agreement may be amended unless such amendment is approved in writing by the
Corporation and made with Two-Thirds Beneficiary Approval; provided that amendment of the definition of Change of Control
will also require the written approval of a majority of the Independent Directors; provided, further, that any change that is reasonably expected to materially adversely affect the Beneficiaries' rights
and obligations under this Agreement shall require the consent (which shall not to be unreasonably withheld, delayed or conditioned)
of each Beneficiary that will be materially adversely affected by such change.  No provision of this Agreement may be
waived unless such waiver is in writing and signed by the Party against whom the waiver is to be effective.

 

(c)               
Successors.  All of the terms and provisions of this Agreement shall be binding upon, and shall inure to the
benefit of and be enforceable by, the Parties hereto and their respective successors, assigns, heirs, executors, administrators
and legal representatives.  The Corporation shall require and cause any direct or indirect successor (whether by purchase,
merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, by written agreement,
expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be
required to perform if no such succession had taken place.

 

(d)              
Waiver.  No failure by any Party to insist upon the strict performance of any covenant, duty, agreement, or
condition of this Agreement, or to exercise any right or remedy consequent upon a breach thereof, shall constitute a waiver of
any such breach or any other covenant, duty, agreement, or condition.

7.7.           
Titles and Subtitles. The headings and titles of the sections and subsections of this Agreement are for convenience
of reference only and are not to be considered in construing this Agreement.

 

7.8.           
Resolution of Disputes.

 

(a)               
Except for Reconciliation Disputes subject to Section 7.9, any and all disputes which cannot be settled after
substantial good-faith negotiation, including any ancillary claims of any Party, arising out of, relating to or in connection with
the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity,
scope and enforceability of this arbitration provision) (each a “Dispute”) shall be finally resolved by arbitration
in accordance with the International Institute for Conflict Prevention and Resolution Rules for Non-Administered Arbitration
by a panel of three arbitrators, of which the Corporation shall designate one arbitrator and the Beneficiaries party to such Dispute
shall designate one arbitrator in accordance with the “screened” appointment procedure provided in Resolution Rule 5.4. 
The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1 et seq., and judgment upon
the award rendered by the arbitrators may be entered by any court having jurisdiction thereof.  The place of the arbitration
shall be New York, New York.

 

(b)              
Notwithstanding the provisions of paragraph (a), any Party may bring an action or special proceeding in any court of competent
jurisdiction for the purpose of compelling another Party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration
hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), each Party (i) expressly consents
to the application of paragraph (c) of this Section 7.8 to any such action or proceeding, and (ii) agrees that
proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate
and that remedies at law would be inadequate.  For the avoidance of doubt, this Section 7.8 shall not apply to Reconciliation
Disputes to be settled in accordance with the procedures set forth in Section 7.9.

 

(c)               
Each Party hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of
the Chancery Court of the State of Delaware or, if such Court declines jurisdiction, the courts of the State of Delaware sitting
in Wilmington, Delaware, and of the U.S. District Court for the District of Delaware sitting in Wilmington, Delaware, and any appellate
court from any thereof, in any action or proceeding arising out of or relating to this Agreement or for recognition or enforcement
of any judgment, and each of the Parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action
or proceeding may be heard and determined in such Delaware State court or, to the fullest extent permitted by applicable law, in
such U.S. District Court.  Each Party agrees that a final judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

 

(d)              
Each Party irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that it may now
or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any
court referred to in Section 7.8(c).  Each Party irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of any such suit, action or proceeding in any such court.

 

(e)               
Each Party irrevocably consents to service of process by means of notice in the manner provided for in Section 7.1. 
Nothing in this Agreement shall affect the right of any Party to serve process in any other manner permitted by law.

 

(f)               
WAIVER OF RIGHT TO TRIAL BY JURY.  EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

 

(g)              
Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of Section 7.9, or a Dispute within
the meaning of this Section 7.8, shall be decided and resolved as a Dispute subject to the procedures set forth in this
Section 7.8.

    	20

    	 

    

 

7.9.           
Reconciliation.  In the event that the Corporation and any Beneficiary are unable to resolve a disagreement
with respect to a Schedule (other than an Early Termination Schedule) prepared in accordance with the procedures set forth in Section 2.6,
or with respect to an Early Termination Schedule prepared in accordance with the procedures set forth in Section 4.2,
within the relevant time period designated in this Agreement (a “Reconciliation Dispute”), the Reconciliation
Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular
area of disagreement mutually acceptable to both Parties.  The Expert shall be a partner or principal in a nationally recognized
accounting firm, and unless the Corporation and such Beneficiary agree otherwise, the Expert shall not, and the firm that employs
the Expert shall not, have any material relationship with the Corporation or such Beneficiary or other actual or potential conflict
of interest.  If the Parties are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of
written notice of a Reconciliation Dispute, the selection of an Expert shall be treated as a Dispute subject to Section 7.8
and an arbitration panel shall pick an Expert from a nationally recognized accounting firm that does not have any material relationship
with the Corporation or such Beneficiary or other actual or potential conflict of interest.  The Expert shall resolve any
matter relating to the Basis Schedule or an amendment thereto, or the Early Termination Schedule or an amendment thereto within
thirty (30) calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen
(15) calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the
Expert for resolution.  Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the
subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement
is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared
by the Corporation, subject to adjustment or amendment upon resolution.  The costs and expenses relating to the engagement
of such Expert or amending any Tax Return shall be borne by the Corporation except as provided in the next sentence.  The
Corporation and the Beneficiaries shall bear their own costs and expenses of such proceeding, unless (i) the Expert adopts
the Beneficiary’s position, in which case the Corporation shall reimburse the Beneficiary for any reasonable and documented
out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporation’s position, in which
case the Beneficiary shall reimburse the Corporation for any reasonable and documented out-of-pocket costs and expenses in such
proceeding.  The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to
this Section 7.9 shall be binding on the Corporation and the Beneficiaries and may be entered and enforced in any court
having competent jurisdiction.

 

7.10.       
Withholding. The Corporation shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement
such amounts as the Corporation is required to deduct and withhold with respect to the making of such payment any provision of
U.S. federal, state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate Taxing
Authority by the Corporation, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to
the applicable Beneficiary. Each Beneficiary shall promptly provide the Corporation with any applicable tax forms and certifications
reasonably requested by the Corporation in connection with determining whether any such deductions and withholdings are required
under any provision of U.S. federal state, local or foreign tax law.

 

7.11.       
Admission of the Corporation into a Consolidated Group; Transfers of Corporate Assets.

 

(a)               
If the Corporation becomes a member of an affiliated or consolidated group of corporations that files a consolidated income
tax return pursuant to Sections 1501, et seq. or other applicable Sections of the Code or any corresponding provisions of
state, local or foreign law, then: (i) the provisions of this Agreement shall be applied with respect to the group as a whole;
and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference
to the consolidated taxable income of the group as a whole.

 

(b)              
If the Corporation (or any other entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder)
or any member of the OTG Management Group transfers (or is deemed to transfer) one or more assets to a corporation with which the
Corporation or any other entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder does not
file a consolidated tax return pursuant to Section 1501 of the Code (or will not file such a return following a series of transactions
undertaken in connection with such transfer(s)), such entity, for purposes of calculating the amount of any Tax Benefit Payment
or Early Termination Payment due hereunder, shall be treated as having disposed of such asset in a fully taxable transaction on
the date of such contribution.  The consideration deemed to be received by such entity shall be equal to the fair market value
of the contributed asset, plus (i) the amount of debt to which such asset is subject, in the case of a contribution of an encumbered
asset, or (ii) the amount of debt allocated to such asset, in the case of a contribution of a partnership interest.

    	21

    	 

    

 

7.12.       
Confidentiality. Each Beneficiary and its assignees acknowledges and agrees that the information of the Corporation
is confidential and, except in the course of performing any duties as necessary for the Corporation and its Affiliates, as required
by law or legal process or to enforce the terms of this Agreement, such Person shall keep and retain in the strictest confidence
and not disclose to any Person any confidential matters, acquired pursuant to this Agreement, of the Corporation and its Affiliates
and successors, learned by any Beneficiary heretofore or hereafter.  This Section 7.12 shall not apply to (i) any
information that has been made publicly available by the Corporation or any of its Affiliates, becomes public knowledge (except
as a result of an act of any Beneficiary in violation of this Agreement) or is generally known to the business community, (ii) the
disclosure of information to the extent necessary for a Beneficiary to prosecute or defend claims arising under or relating to
this Agreement, and (iii) the disclosure of information to the extent necessary for a Beneficiary to prepare and file its
Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding
or audit by any Taxing Authority with respect to such Tax Returns.  Notwithstanding anything to the contrary herein, the Beneficiaries
and each of their assignees (and each employee, representative or other agent of the Beneficiaries or their assignees, as applicable)
may disclose at their discretion to any and all Persons, without limitation of any kind, the tax treatment and tax structure of
the Corporation, the Beneficiaries and any of their transactions, and all materials of any kind (including tax opinions or other
tax analyses) that are provided to the Beneficiaries relating to such tax treatment and tax structure.  If a Beneficiary or
an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.12, the Corporation
shall have the right and remedy to have the provisions of this Section 7.12 specifically enforced by injunctive relief
or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged
and agreed that any such breach or threatened breach shall cause irreparable injury to the Corporation or any of its Subsidiaries
and that money damages alone shall not provide an adequate remedy to such Persons.  Such rights and remedies shall be in addition
to, and not in lieu of, any other rights and remedies available at law or in equity.

 

7.13.       
Independent Nature of Beneficiaries’ Rights and Obligations. The rights and obligations of each Beneficiary
hereunder are several and not joint with the rights and obligations of any other Person.  A Beneficiary shall not be responsible
in any way for the performance of the obligations of any other Person hereunder, nor shall a Beneficiary have the right to enforce
the rights or obligations of any other Person hereunder (other than the Corporation).  The obligations of a Beneficiary hereunder
are solely for the benefit of, and shall be enforceable solely by, the Corporation.  Nothing contained herein or in any other
agreement or document delivered at any closing, and no action taken by any Beneficiary pursuant hereto or thereto, shall be deemed
to constitute the Beneficiaries acting as a partnership, an association, a joint venture or any other kind of entity, or create
a presumption that the Beneficiaries are in any way acting in concert or as a group with respect to such rights or obligations
or the transactions contemplated hereby, and the Corporation acknowledges that the Beneficiaries are not acting in concert or as
a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated hereby.

 

7.14.       
Change in Law.  Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed
change in law, a Beneficiary reasonably believes that the existence of this Agreement could cause income (other than income arising
from receipt of a payment under this Agreement) recognized by such Beneficiary (or direct or indirect equity holders in such Beneficiary)
in connection with any Exchange to be treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income
rates) for U.S. federal income tax purposes or would have other material adverse tax consequences to such Beneficiary or any direct
or indirect owner of such Beneficiary, then at the written election of such Beneficiary in its sole discretion (in an instrument
signed by such Beneficiary and delivered to the Corporation) and to the extent specified therein by such Beneficiary, this Agreement
shall cease to have further effect and shall not apply to an Exchange occurring after a date specified by such Beneficiary, or
may be amended by in a manner reasonably determined by such Beneficiary; provided that such amendment shall not result in
an increase in any payments owed by the Corporation under this Agreement at any time as compared to the amounts and times of payments
that would have been due in the absence of such amendment.

 

7.15.       
Interest Rate Limitation.  Notwithstanding anything to the contrary contained herein, the interest paid or agreed
to be paid hereunder with respect to amounts due to any Beneficiary hereunder shall not exceed the maximum rate of non-usurious
interest permitted by applicable Law (the “Maximum Rate”).  If any Beneficiary shall receive interest in
an amount that exceeds the Maximum Rate, the excess interest shall be applied to the Tax Benefit Payment or Early Termination Payment,
as applicable (but in each case exclusive of any component thereof comprising interest) or, if it exceeds such unpaid non-interest
amount, refunded to the Corporation.  In determining whether the interest contracted for, charged, or received by any Beneficiary
exceeds the Maximum Rate, such Beneficiary may, to the extent permitted by applicable Law, (a) characterize any payment that
is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof,
and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated
term of the payment obligations owed by the Corporation to such Beneficiary hereunder.  Notwithstanding the foregoing, it
is the intention of the Parties to conform strictly to any applicable usury laws.
