The Borrower has advised us that, pursuant to that certain Agreement and Plan of Merger, among the Borrower, Aytu Bioscience, Inc., a Delaware corporation (“Aytu”; and together with its Subsidiaries (prior to giving effect to the Merger), the “Aytu Group”), and Neutron Acquisition Sub., Inc.. a Delaware corporation, dated as of the date hereof (together with all exhibits, schedules and disclose letters thereto, the “Merger Agreement”), Aytu intends to acquire the Borrower (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Transactions”) and, in connection therewith, (a) the Borrower has requested that the Lenders consent to the issuance of the Convertible Note (as defined below) on the date hereof, (b) the Borrower and Aytu have requested that, on the Closing Date (as defined below), the Lenders (i) consent to the consummation of the Merger, (ii) waive the Event of Default due to the Change of Control that would arise without such consent, and (iii) agree to certain other amendments to, and waivers of, provisions of the Facility Agreement and the other Loan Documents, in each case as set forth in the term sheet attached hereto as Annex A (the “Term Sheet”), (c) the Borrower has requested that, on the Closing Date, the Lenders irrevocably waive (i) (A) the Going Concern Condition (as defined in that certain letter agreement by and among the Borrower and the Lenders dated as of November 6, 2020) for each of the fiscal quarters ended June 30, 2020 and September 30, 2020 and each other fiscal quarter ending thereafter and prior to the Closing Date and (B) any Event of Default that would arise without such waiver due to the failure to satisfy the Going Concern Condition (as defined in that certain letter agreement by and among the Borrower and the Lenders dated as of November 6, 2020) for each of the fiscal quarters ended June 30, 2020 and September 30, 2020 and each other fiscal quarter ending thereafter and prior to the Closing Date as required pursuant to Section 5.1(v) of the Facility Agreement and (ii) the right to impose the default rate of interest under Section 2.8 of the Facility Agreement, or to collect interest accruing at such default rate of interest, that Lenders had a lawful right to collect or apply with respect to any such Event of Default for failure to satisfy such Going Concern Condition, and (d) the Borrower has requested that, on the Closing Date, the Lenders consent to certain amendments to, and waivers of, provisions of the ABL Agreement or other ABL Documents (such amendments, collectively, the “ABL Modification”) on the terms of the commitment letter attached hereto as Annex B (the “ABL Commitment Letter”). The consent, waiver and other amendments and modifications described in the foregoing clauses (b) through (d) are sometimes hereinafter referred to collectively as the “Closing Date Modifications”. This letter agreement, including the Term Sheet and the Conditions Annex attached hereto and thereto are herein referred to collectively as the “Letter Agreement.” The date on which the Merger is consummated is referred to as the “Closing Date,” which shall be the date on which all conditions under this Letter Agreement are satisfied (or waived in writing by the Lenders).

1. Consent. The Borrower has advised us that, on the date hereof, the Borrower intends to issue to Aytu that certain Unsecured Convertible Promissory Note in the form attached hereto as Annex B (the “Convertible Note”), the proceeds of which, if any, will be used by the Borrower to pay certain of its general corporate expenses during the period from the date hereof until the Closing Date. In connection therewith, the Borrower has requested that the Lenders consent to the issuance of the Convertible Note and the incurrence of the Indebtedness contemplated thereby. Provided that the Borrower and Aytu shall have executed and delivered to the Lenders a subordination agreement, in the form attached hereto as Annex C (the “Convertible Note Subordination Agreement”), and notwithstanding anything to the contrary set forth in the Facility Agreement or any other Loan Document, the Lenders hereby consent to the Borrower’s issuance of the Convertible Note and incurrence of the Indebtedness thereunder.

2. Closing Date Modifications. Upon the terms of this Letter Agreement, and subject only to the conditions set forth in Section 3 below and in the Conditions Annex, the Lenders agree that they shall be obligated to consummate the Closing Date Modifications on the Closing Date.

3. Conditions to Closing Date Modifications.

For purposes hereof, “Specified Representations” means the representations and warranties set forth in Sections 3.1(c), 3.1(g), 3.1(i), 3.1(q) (solely as it relates to the execution, delivery and performance of the Amendment Documentation (as defined in the Conditions Annex)), 3.1(aa), 3.1(hh), 3.1(pp), and 3.1(qq) of the Facility Agreement, in each case after giving effect to the Merger and in each case with respect to both the Borrower and its Subsidiaries and Aytu and its other Subsidiaries.

Each of the Borrower and Aytu hereby acknowledges and agrees that no Applicable Person shall have any duty of trust or confidence with respect to any material non-public information provided to any Applicable Person in breach of, or otherwise possessed by any Applicable Person as a result of a breach of, any of the foregoing covenants. Notwithstanding anything to the contrary contained herein, in the event of a breach of any of the foregoing covenants, in addition to any other remedies available at law or in equity, the Lenders and their Affiliates shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of the applicable material non-public information without the prior approval by the Borrower, Aytu or any other Person. For the avoidance of doubt, the parties hereto acknowledge and agree that nothing contained in this Section 4 shall limit the obligations of the Borrower under, or the rights of the Lenders under, Section 5.1(xiii) of the Facility Agreement.

5. Acceptance/Expiration of Letter Agreement.

2. Subordination.

2.1. Subordination of Subordinated Loans to Senior Loans. Borrower covenants and agrees, and Subordinated Lender likewise covenants and agrees that, notwithstanding anything to the contrary contained in any of the Subordinated Loan Documents, the payment of any and all of the Subordinated Loans shall be subordinate and subject in right and time of payment, to the extent and in the manner hereinafter set forth, to the Payment in Full of all Senior Loans. Each holder of the Senior Loans, whether now outstanding or hereafter created, incurred, assumed or guaranteed, shall be deemed to have consented to the Subordinated Loans in reliance upon the provisions contained in this Agreement. Until the Senior Loans have been Paid in Full, Borrower shall not make, and Subordinated Lenders shall not accept, any Distribution on account of any Subordinated Loan, other than (i) regularly scheduled payments of capitalized payments-in-kind of accrued interest (but not, for the sake of clarity, any payments in cash) on the Subordinated Loan due and payable on a non-accelerated basis, (ii) payments effected through conversion of indebtedness under the Subordinated Loan to common stock of Borrower (or other qualified capital stock (on terms and conditions reasonably satisfactory to Senior Lenders) of Borrower) and (iii) payments effected through conversion of the indebtedness under the Subordinated Loan to other indebtedness so long as, to the extent Borrower is an obligor thereunder, such convertible indebtedness is subject to a subordination agreement on the same terms and conditions of this Agreement and otherwise satisfactory to Senior Lenders. Subordinated Lender expressly acknowledges and agrees that if Borrower’s failure to make any payments due and payable to the Subordinated Lender under the Subordinated Loan Documents is due solely to this Agreement prohibiting any such payments, such failure shall not constitute a default or event of default under the Subordinated Loan Documents.

2.2. Subordinated Loan Standstill. Until the Senior Loans are Paid in Full, Subordinated Lender shall not, without the prior written consent of Senior Lenders, take any Enforcement Action with respect to the Subordinated Loans.

2.3. Incorrect Payments. If any Distribution on account of the Subordinated Loan not permitted to be made by Borrower or accepted by Subordinated Lender under this Agreement is made to and received by Subordinated Lender, such Distribution shall not be commingled with any of the assets of Subordinated Lender, shall be held in trust by Subordinated Lender for the benefit of Senior Lenders and shall be promptly paid over to the Senior Lenders for application in accordance with the Senior Loan Documents to the payment of the Senior Loans then remaining unpaid, until all of the Senior Loans are Paid in Full.

2.4. Subordination of Liens and Security Interests; Agreement Not to Contest; Agreement to Release any Liens. Subordinated Lender hereby acknowledges, agrees, represents and warrants that none of the Subordinated Loans nor any portion thereof is as of the date hereof, or at any time in the future shall be, secured by any lien or security interest in any of the Collateral, the equity interests in Borrower or any other asset of Borrower, or guaranteed by any Person. Without limiting the foregoing, until the Senior Loans have been Paid in Full, all liens and security interests of Subordinated Lender in the Collateral, if any, shall be and hereby are subordinated for all purposes and in all respects to the liens and security interests of Senior Lenders in the Collateral, regardless of the time, manner or order of perfection of any such liens and security interests and regardless of any failure, whether intervening or continuing, of Senior Lenders’ liens and security interests to be perfected; provided, however, that each of the parties hereto acknowledges and agrees that the existence of any lien or security interest of Subordinated Lender would constitute an automatic and immediate Event of Default under the Facility Agreement and a breach of this Agreement. Subordinated Lender agrees that it will not at any time contest the validity, perfection, priority or enforceability of the Senior Loans, the Senior Loan Documents, or the liens and security interests of Senior Lenders in the Collateral securing the Senior Loans. In the event that any lien or security interest arises in favor of Subordinated Lender, immediately upon Senior Lenders’ request, Subordinated Lender shall or shall cause its agent to promptly execute and deliver to Senior Lenders such termination statements and releases as Senior Lenders shall reasonably request to effect the release of the liens and security interests of Subordinated Lender in any such Collateral.

2.5. Sale, Transfer or other Disposition of Subordinated Loan. The Subordinated Lender shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Subordinated Loans or any Subordinated Loan Document without the prior written consent of the Senior Lenders. Without limiting the foregoing, if any such sale, assignment, pledge, disposition or other transfer is made in contravention of this Agreement, the subordination effected hereby shall survive such sale, assignment, pledge, disposition or other transfer of all or any portion of the Subordinated Loans, and the terms of this Agreement shall be binding upon the successors and assigns of the Subordinated Lender.

2.6. Legends. Until the termination of this Agreement in accordance with Section 8 hereof, Subordinated Lender will cause to be clearly, conspicuously and prominently inserted on the face of each Subordinated Loan Document, the following legend:

“This instrument or other agreement and the indebtedness, rights and obligations evidenced hereby are subordinate in the manner and to the extent set forth in that certain Subordination Agreement, dated as of [●], 202[●] (as amended, restated, supplemented or modified from time to time, the “Subordination Agreement”), by and among (I) neos therapeutics, inc. (the “Company”), (II) the Subordinated Lender identified therein, and (III) Deerfield Private Design Fund III, L.P. and DEERFIELD PARTNERS, L.P., AND THEIR RESPECTIVE successors and assigns (the “Senior LenderS”), to certain indebtedness, rights and obligations of Obligors to the Senior LenderS, and all liens and security interests of Senior Lender securing the same, all as described in the Subordination Agreement, and each holder and transferee of this instrument or agreement, by its acceptance hereof, irrevocably agrees to be bound by the provisions of the Subordination Agreement.”

2.7. Liquidation, Dissolution, Bankruptcy. In the event of any Proceeding involving Borrower:

(a) Any Distribution, whether in cash, securities or other property, that would otherwise, but for the terms hereof, be payable or deliverable in respect of the Subordinated Loan, shall be paid or delivered directly to the Senior Lenders (to be held and/or applied by Senior Lenders in accordance with the terms of the Senior Loan Documents) until all of the Senior Loans are Paid in Full. Subordinated Lender irrevocably authorizes, empowers and directs any debtor, debtor in possession, receiver, trustee, liquidator, custodian, conservator or other Person having authority, to pay or otherwise deliver all such Distributions to Senior Lenders. Subordinated Lender also irrevocably authorizes and empowers Senior Lenders, in the name of Subordinated Lender, to demand, xxx for, collect and receive any and all such Distributions.

(b) Subordinated Lender agrees that Senior Lenders may consent to the use of cash collateral or provide financing to the Borrower on such terms and conditions and in such amounts as Senior Lenders, in their sole discretion, may decide and, in connection therewith, the Borrower may grant to Senior Lenders liens and security interests upon all of the property of Borrower, which liens and security interests (i) shall secure payment of the Senior Loans (whether such Senior Loans arose prior to the commencement of any Proceeding or at any time thereafter) and all other financing provided by Senior Lenders during the Proceeding, and (ii) shall be superior in priority to the liens and security interests, if any, in favor of Subordinated Lender on the property of Borrower. Subordinated Lender agrees that it will not object to or oppose a sale or other disposition of any property securing all of any part of the Senior Loans free and clear of security interests, liens or other claims of Subordinated Lender under Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code if Senior Lenders have consented to such sale or disposition. Subordinated Lender agrees not to assert any right it may have to “adequate protection” of Subordinated Lender’s interest in any Collateral in any Proceeding. Subordinated Lender waives any claim it may now or hereafter have arising out of Senior Lenders’ election, in any Proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b)(2) of the Bankruptcy Code, and/or any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code by the Borrower, as debtor in possession. Subordinated Lender further agrees that it will not seek to participate or participate on any creditors’ committee of the Borrower without Senior Lenders’ prior written consent.

(c) Subordinated Lender agrees to execute, verify, deliver and file any proofs of claim in respect of the Subordinated Loans requested by Senior Lenders in connection with any such Proceeding and hereby irrevocably authorizes, empowers and appoints Senior Lenders as its agent and attorney-in- fact to (i) execute, verify, deliver and file such proofs of claim upon the failure of Subordinated Lender promptly to do so prior to thirty (30) days before the expiration of the time to file any such proof of claim, and (ii) vote such claim in any such Proceeding upon the failure of Subordinated Lender to do so prior to fifteen (15) days before the expiration of the time to vote any such claim; provided, however, that Senior Lenders shall have no obligation to execute, verify, deliver, file and/or vote any such proof of claim. In the event that Senior Lenders vote any claim in accordance with the authority granted hereby, Subordinated Lender shall not be entitled to change or withdraw such vote. Subordinated Lender hereby assigns to Senior Lenders or their nominee (and will, upon request of Senior Lenders, reconfirm in writing the assignment to Senior Lenders or its nominee of) all of its rights under such claims.

(d) The Senior Loans shall continue to be treated as the Senior Loans and the provisions of this Agreement shall continue to govern the relative rights and priorities of Senior Lenders and Subordinated Lender even if all or part of the Senior Loans or the security interests securing the Senior Loans are subordinated, set aside, avoided, invalidated or disallowed in connection with any such Proceeding, and this Agreement shall be reinstated if at any time any payment of any of the Senior Loans is rescinded or must otherwise be returned by any holder of the Senior Loans or any representative of such holder.

3. Modifications.

3.1. Modifications to Senior Loan Documents. Senior Lenders may at any time and from time to time without the consent of Subordinated Lenders, without providing any notice to the Senior Lenders, without incurring liability to Subordinated Lenders and without impairing or releasing the obligations of Subordinated Lender under this Agreement, change the manner or place of payment or alter any of the terms of the Senior Loans, or amend in any manner any agreement, note, guaranty or other instrument evidencing or securing or otherwise relating to the Senior Loans.

3.2. Modifications to Subordinated Loan Documents; Maximum Principal Amount of Subordinated Loan. Until the Senior Loans have been Paid in Full, and notwithstanding anything to the contrary contained in the Subordinated Loan Documents, Subordinated Lender shall not, without the prior written consent of the Senior Lenders, agree to any amendment, modification or supplement to the Subordinated Loan Documents other than, so long as a copy is provided to Senior Lenders, an amendment for the sole purpose of extending the maturity date of the Subordinated Loans. Nothing herein, including the provisions of this Agreement pertaining to subordination of liens on the Collateral, shall be construed to imply Senior Lenders’ consent to any Subordinated Loan Document which grants a lien upon any of the Collateral or the making of any other loans or other advances by Subordinated Lender.

4. Waiver of Certain Rights by Subordinated Lender.

4.1. Marshaling. Subordinated Lender hereby waives any rights it may have under applicable law to assert the doctrine of marshaling or to otherwise require Senior Lenders to marshal any property of Borrower or any other guarantor of the Senior Loans for the benefit of Subordinated Lender.

4.2. Rights Relating to Senior Lenders’ Actions with respect to the Collateral. Subordinated Lender hereby waives, to the extent permitted by applicable law, any rights which it may have to enjoin or otherwise obtain a judicial or administrative order preventing any Senior Lender from taking, or refraining from taking, any action with respect to all or any part of the Collateral. Without limitation of the foregoing, Subordinated Lender hereby agrees (a) that it has no right to direct or object to the manner in which Senior Lender enforces its rights and remedies with respect to, or applies the proceeds of the Collateral resulting from the exercise by any Senior Lender of rights and remedies under the Senior Loan Documents to the Senior Loans, and (b) that no Senior Lender has assumed any obligation to act as the agent for Subordinated Lender with respect to the Collateral.

4.3. Rights Relating to Disclosures. Subordinated Lender hereby agrees that Senior Lenders have not assumed any obligation or duty to disclose information regarding Borrower or the Senior Loans to Subordinated Lender, and Senior Lenders shall not have a special or fiduciary relationship to Subordinated Lender. Subordinated Lender hereby fully waives and releases Senior Lenders from any affirmative disclosures which may be required of Senior Lenders under applicable law.

5. Construction. The terms of this Agreement were negotiated among business persons sophisticated in the area of business finance, and accordingly, in construing the terms of this Agreement, no rule or law which would require that this instrument be construed against the party who drafted this instrument shall be given any force or effect.

6. Modification of this Agreement. No modification or waiver of any provision of this Agreement, or consent to any departure by any party from the terms hereof, shall be effective in any event unless the same is in writing and signed by Senior Lenders or such other holder of the Senior Loans and Subordinated Lender or such other holder of the Subordinated Loans, and then such modification, waiver or consent shall be effective only in the specific instance and for the specific purpose given. Any notice to or demand on any party hereto in any event not specifically required hereunder shall not entitle the party receiving such notice or demand to any other or further notice or demand in the same, similar or other circumstances unless specifically required hereunder.

7. Further Assurances. Each party to this Agreement promptly will execute and deliver such further instruments and agreements and do such further acts and things as may be reasonably requested in writing by any other party hereto that may be necessary or desirable in order to effect fully the purposes of this Agreement.

8. Continuing Agreement. This is a continuing agreement and will remain in full force and effect until all of the obligations under the Senior Loan Documents have been Paid in Full after which this Agreement shall terminate without further action on the part of the parties hereto; provided, that if any payment is, subsequent to such termination, recovered from any holder of Senior Loans, this Agreement shall be reinstated. This Agreement will continue to be effective or will be reinstated, as the case may be, if at any time payment of all or any part of the Senior Loan Documents or the obligations thereunder is rescinded or must otherwise be returned by Senior Lenders upon insolvency, bankruptcy, or reorganization of any Obligor or otherwise, all as though such payment had not been made.
