of Rights. Except with respect to the Existing Event of Default, Lender is not committed to and has not agreed to forbear from exercising
any rights or remedies. The parties hereto have not established any course of conduct by past action or inaction or by the execution
of this Agreement, the other Loan Documents or otherwise. Nothing in this Agreement or the other Loan Documents, nor any past action
or inaction of Lender shall constitute, or has constituted, a waiver of the Existing Event of Default, any other Default or Event of
Default or of any of Lender’s rights and remedies under the Loan Documents or at law or in equity. To the contrary, Lender expressly
reserves, and Loan Parties acknowledge and agree that at all times Lender has expressly reserved, all of its rights and remedies in respect
of the Existing Event of Default and any other Default or Event of Default. Notwithstanding any previous practice to the contrary and
for the avoidance of doubt, each Loan Party acknowledges and agrees that all Obligations shall be due and payable upon the expiration
(due to the passage of time) or termination (due to the occurrence of a Forbearance Default) of the Forbearance Period (the date whichever
occurs first being referred to in this Agreement as the “Forbearance Termination Date”) and that Lender shall be entitled
to exercise its rights and remedies immediately upon the failure of Borrower to pay any amounts as and when due hereunder. If and to
the extent that Lender forbears from taking action after the Forbearance Termination Date, Lender will be doing so on a voluntary day-to-day
basis in its sole and absolute discretion.

13. General
Release. As further inducement to Lender to enter into this Agreement, Loan Parties hereby release Lender as follows:

 

(a) Loan
Parties and their heirs, successors and assigns and its heirs, successors and assigns (collectively, the “Releasing Parties”)
do hereby release, acquit and forever discharge Lender and any other present or future holder of a legal or equitable interest in the
Loan, and their respective parents, affiliates, subsidiaries, successors in interest, transferees, assigns, officers, directors, employees,
managers, attorneys, accountants, agents, and servants, and each of them, in all capacities, including individually (collectively “Lender
Parties”) of and from any and all claims, demands, obligations, liabilities, indebtedness, breaches of contract, breaches of
duty or any relationship, acts, omissions, misfeasance, malfeasance, cause or causes of action, debts, sums of money, accounts, compensation,
contracts, controversies, promises, damages, costs, losses and expenses of every type, kind, nature, description, or character, whether
known or unknown, suspected or unsuspected, liquidated or unliquidated, each as though fully set forth herein at length, which in any
way, have, prior to the Effective Date whether or not they are connected with or related to the Loan Documents, the Combination LOI or
otherwise (collectively, the “Released Claims”).

 

(b) The
agreement of the Releasing Parties, as set forth in the preceding subparagraph (a) shall inure to the benefit of the successors,
assigns, insurers, administrators, agents, employees, and representatives of Lender.

 

(c) Each
Releasing Party acknowledges and agrees that the Released Claims include, among other things, any claims for fraud, promissory fraud,
or any other claim arising from any oral or written promises, representations, assurances, agreements, statements or advice (including
without limitation any such promises or other statements that are inconsistent with any of the provisions of this Agreement or any of
the other Loan Documents) made or given or allegedly made or given by any officer, employee, agent, attorney or other representative
of any Released Party that are or were false or allegedly false or that were made or allegedly made without intent to perform the same.

 

(d) The
Releasing Parties have read the foregoing release, fully understand the legal consequences thereof and have had the opportunity to obtain
the advice of counsel with respect thereto. The Releasing Parties further warrant and represent that they are authorized to make the
foregoing release.

 

(e) Each
Releasing Party acknowledges that the foregoing release shall extend to Released Claims which the Releasing Party does not know or suspect
to exist in Releasing Party’s favor at the time of executing this Agreement, regardless of whether such Released Claims, if known by
such Releasing Party, would have materially affected such Releasing Party’s decision to enter into this Agreement.

 

(f) Each
Releasing Party warrants and represents that he or it is the sole and lawful owner of all right, title and interest in and to all of
the respective Released Claims released hereby and that he or it has not heretofore voluntarily, by operation of law or otherwise, assigned
or transferred or purported to assign or transfer to any person or entity any such claim or any portion thereof. If any Releasing Party
shall have assigned or transferred, or purported to assign or transfer, any Released Claim released by this release, then such Releasing
Party shall indemnify the Lender Parties and hold the Lender Parties harmless from and against any loss, cost, claim or expense including
but not limited to all costs related to the defense of any action, including reasonable attorneys’ fees, based upon, arising out of,
or incurred as a result of any such assigned or transferred Released Claim.

 

(g) This
release is not to be construed and does not constitute an admission of liability on the part of Lender. This release shall constitute
an absolute bar to any Released Claim of any kind, whether such claim is based on contract, tort, warranty, mistake or any other theory,
whether legal, statutory or equitable. The Releasing Parties specifically agree that any attempt to assert a claim barred hereby shall
subject each of them to the provisions of applicable law setting forth the remedies for the bringing of groundless, frivolous or baseless
claims or causes of action.

 

14. Remedies.
Upon the occurrence of a Forbearance Default or the expiration of the Forbearance Period, Lender shall be entitled to exercise all rights
and remedies, including, without limitation, all rights of a secured creditor available to it under applicable law and equity. Without
limiting the foregoing, Lender shall be entitled to seek the immediate, ex parte, appointment of a receiver for Borrower or any other
Collateral to which any Loan Party has granted any interest and each Loan Party hereby stipulates and agrees to stipulate. All such rights
and remedies shall be cumulative. No failure or delay on the part of Lender in exercising any power, right or remedy under any of the
Loan Documents shall operate as a waiver thereof, and no single or partial exercise of any such power, right or remedy shall preclude
any further exercise thereof or the exercise of any other power, right or remedy.

 

    8

Defaults. Upon the occurrence of any of the following (each a “Forbearance Default”), at Lender’s
option, the Forbearance Period shall immediately terminate without demand, presentment or notice, all of which requirements Loan Parties
hereby waive, at which time the Forbearance Termination Date shall have occurred:

 

		a)	Violation
                                            of any of any of its respective covenants, agreements or other obligations set forth in this

                                            with Section 6); or

 

		b)	The
                                            occurrence of any Default or Event of Default other than the Existing Event of Default.

18. Miscellaneous
Provisions.

 

		a)	Effect
                                            of Agreement. Except as specifically set forth in this Agreement, all of the representations,
                                            warranties, terms and conditions of the Loan Documents remain unaltered and in full force
                                            and effect in accordance with their respective terms. In the event of any inconsistency between
                                            the terms of this Agreement and any other Loan Document, this Agreement shall govern. Each
                                            Loan Party acknowledges that it has consulted with counsel and such other experts and advisors
                                            as it deems necessary in connection with the negotiation, execution and delivery of this
                                            Agreement, or has had an opportunity to so consult and has knowingly chosen not to do so.
                                            This Agreement shall be binding upon and inure to the benefit of and be enforceable by the
                                            parties hereto, their respective successors and assigns. No other person shall be entitled
                                            to claim any right or benefit hereunder, except the Released Parties. Nothing herein shall
                                            constitute a novation of any Loan Document.

 

		b)	Fees
                                            and Expenses. Loan Parties shall reimburse Lender for all reasonable attorneys’ fees
                                            and disbursements, receiver’s fees and expenses, expended or incurred by Lender in connection
                                            with: (a) the enforcement of the Loan Documents including, without limitation, during
                                            any workout, attempted workout, and/or in connection with the rendering of legal advice as
                                            to Lenders’ rights, remedies and obligations under the Loan Documents; (b) any arbitration,
                                            mediation, judicial reference proceeding, or other legal action related to any Loan Documents,
                                            (c) collecting any sum which becomes due to Lender under any Loan Document; (d) any
                                            proceeding for declaratory relief, any counterclaim to any proceeding, or any appeal; or
                                            (e) the protection, preservation or enforcement of any rights of Lender. This includes,
                                            subject to any limits under applicable law, Lenders’ attorneys’ fees and legal expenses,
                                            whether or not there is a lawsuit, including attorneys’ fees for bankruptcy or other insolvency
                                            proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals,
                                            and any anticipated post-judgment collection services.

 

		c)	Further
                                            Assurances. Each Loan Party shall execute such additional documents and take such additional
                                            actions as Lender may reasonably request to carry out the purpose and intent of this Agreement
                                            and the Loan Documents.

 

		d)	Time
                                            is of the Essence. Time is of the essence in the performance of this Agreement.

 

		e)	Credit
                                            Agreement Provisions. Article VIII of the Credit Agreement is hereby incorporated herein
                                            by this reference mutatis mutandis. Without limiting the foregoing, Grantor agrees
                                            that this Agreement shall be interpreted in accordance with Delaware law and that any dispute
                                            will be determined by and arbitral tribunal in accordance with Section 8.09(c) of the Credit
                                            Agreement on the “side” of the Borrower.
