(d) Each payment by the Borrower and the other Loan Party Obligors to the Secured Parties in respect of the Obligations shall be applied (i) first, ratably to all fees, costs and expenses (including any attorneys’ fees) owed to any Secured Party under the Loan Documents, but only to the extent such fees, costs and expenses have been invoiced and are due and payable, (ii) second, ratably to accrued and unpaid interest owed to the Lenders and any other Secured Parties, (iii) third, ratably to the outstanding principal amount of the Loans owed to the Lenders (including any Prepayment Fees and Make Whole Interest with respect thereto and any applicable Exit Payment with respect thereto), and, (iv) fourth, to all other Obligations owing to any Secured Party; provided that voluntary prepayments of principal shall be applied against, and reduce, principal payments in the order specified in Section 2.3(e); and, provided, further, that during the continuance of a Default or an Event of Default, payments shall be applied as determined by the Required Lenders in their sole discretion.

No course of dealing and no delay in exercising, or omission to exercise, any right, power or remedy accruing to the Lenders upon any default under this Agreement, or any other agreement shall impair any such right, power or remedy or be construed to be a waiver thereof or an acquiescence therein; nor shall the action of the Lenders in respect of any such default, or any acquiescence by it therein, affect or impair any right, power or remedy of the Lenders in respect of any other default. All rights and remedies herein provided are cumulative and not exclusive of any rights or remedies otherwise provided by law. Section 6.11Indemnity. (a) The Borrower, each Loan Party and Other Obligor shall, at all times, indemnify and hold each Secured Party harmless (the “Indemnity”) and each of their respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified Person”) in connection with any losses, claims (including the reasonable documented out-of-pocket attorneys’ fees incurred in defending against such claims), damages, liabilities, penalties, or other expenses arising out of, or relating to, the Loan Documents, the extension of credit hereunder or the Loan or the use of the Loan, which an Indemnified Person may incur or to which an Indemnified Person may become subject, but excluding all Taxes (each, a “Loss”). The Indemnity shall not apply to the extent that a court or arbitral tribunal of competent jurisdiction issues a final judgment that such Loss resulted from the gross negligence or willful misconduct of any Indemnified Person. The Indemnity is independent of and in addition to any other agreement of Borrower under any Loan Document to pay any amount to the Secured Parties, and any exclusion of any obligation to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under any other agreement. (b) Promptly after receipt by an Indemnified Person under this Section 6.11 of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Loss in respect thereof is to be made against the indemnifying person under this Section 6.11, deliver to Borrower a written notice of the commencement thereof, and Borrower shall have the right to participate in, and, to the extent Borrower so desires, to assume control of the defense thereof. (c) An Indemnified Person shall have the right to retain its own counsel with the documented reasonable fees and out-of-pocket expenses to be paid by the indemnifying person, if, in the reasonable opinion of counsel for the Indemnified Person, the representation by such counsel of the Indemnified Person and Borrower would be inappropriate due to actual or potential differing interests between such Indemnified 79 141540134

Person and any other party represented by such counsel in such proceeding. The Borrower shall pay for only one separate such legal counsel for all of the Indemnified Persons. The failure of an Indemnified Person to deliver written notice to the Borrower within a reasonable time of the commencement of any such action shall not relieve the Borrower of any liability to the Indemnified Person under this Section 6.11, except to the extent that Borrower is actually prejudiced in its ability to defend such action. The indemnification required by this Section 6.11 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable. (d)In no circumstance will any of the Indemnified Persons be liable for lost profits or other special, punitive, or consequential damages. Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, this Section 6.11 shall remain operative even after the payment in full of the Obligations. Section 6.12No Usury. The Loan Documents are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or agreed to be paid to the Lenders for the Loan exceed the maximum amount permissible under applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstance the Lenders shall ever receive anything which might be deemed interest under applicable law that would exceed the highest lawful rate, such amount that would be deemed excessive interest shall be applied to the reduction of the principal amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid balance of principal of the Loan, such deemed excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Lenders for the Loan shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full term of the Loan until payment in full so that the deemed rate of interest on account of the Loan is uniform throughout the term thereof. The terms and provisions of this Section shall control and supersede every other provision of this Agreement and the Notes. Section 6.13Further Assurances.From time to time, the Borrower and the other Loan Party Obligors shall perform (and shall cause their Subsidiaries to perform) any and all acts and execute and deliver to the Secured Parties such additional agreements, instruments and documents as may be reasonably requested by any Secured Party to carry out the purposes of any Loan Document or to preserve and protect the Secured Parties’ rights and remedies as contemplated herein and therein. Section 6.14Confidentiality. Subject to Section 5.1(xiii), Lenders agree that they will hold any confidential information they may receive from Borrower in connection with the Loan Documents in confidence, unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 6.14 by Lenders), (b) is or has been independently developed or conceived by Lenders without use of Borrower’s confidential information, or (c) is or has been made known or disclosed to Lender by a third party without a breach of any obligation of confidentiality such third party may have to 80 141540134

Section 6.15Intercreditor Agreement. (a)Notwithstanding anything to the contrary in this Agreement or in any other Loan Document: (i) the Liens granted to the Collateral Agent in favor of the Secured Parties pursuant to the Loan Documents and the exercise of any right related to any collateral hereunder or thereunder shall be subject, in each case, to the terms of the Intercreditor Agreement, (ii) in the event of any conflict between the express terms and provisions of this Agreement or any other Loan Document, on the one hand, and of the Intercreditor Agreement, on the other hand, the terms and provisions of the Intercreditor Agreement shall control, (iii) any collateral (including the Collateral) under the Loan Documents held by (or in the possession or control of) the ABL Agent (as defined in the Intercreditor Agreement) (or its agents or bailees) shall be held as agent and bailee for security, Lien perfection and control purposes in favor of the Collateral Agent (for the benefit of the Secured Parties) in accordance with the terms of the Intercreditor Agreement and the Loan Documents, and (iv) each Lender hereunder authorizes and instructs the Collateral Agent to execute the Intercreditor Agreement on behalf of such Lender, and such Lender agrees to be bound by the terms thereof. (b) Each Lender hereunder authorizes and instructs the Collateral Agent, as the Collateral Agent and on behalf of such Lender, to enter into one or more intercreditor agreements (including the Intercreditor Agreement) from time to time pursuant to, or as contemplated by, the terms of this Agreement and agrees that it will be bound by the terms and provisions thereof and will take no actions contrary to the terms and provisions thereof. (c) Notwithstanding anything herein to the contrary, each of (i) the Obligations of the Loan Parties under this Agreement, (ii) the Lien and security interest granted to the Collateral Agent for the benefit of the Secured Parties pursuant to this Agreement and the other Loan Documents (including priority thereof), (iii) the release of Collateral from the Lien granted and created by the Loan Documents and (iv) the exercise of any right or remedy by the Collateral Agent under the Loan Documents are, in each case, subject to the provisions of the Intercreditor Agreement. In the event of any conflict or inconsistency between the provisions of the Intercreditor Agreement and this Agreement, the provisions of the Intercreditor Agreement shall control. 81 141540134

Share Issuance. (a) On each Interest Payment Date in respect of which a Share Issuance Notice has been delivered hereunder to provide for the satisfaction of interest through the issuance of Freely Tradeable Shares, by no later than 9:00 a.m., New York City time, the Borrower shall deliver to each Lender its Pro Rata Share of the applicable by causing the transfer Ex.2.3-4 141540134

agent for the Common Stock to electronically transmit such Interest Payment Shares to such Lender by crediting to the account of such Lender’s prime broker (as specified by such Lender no later than one Trading Day prior to the Interest Payment Date) with DTC through its Deposit/Withdrawal at Custodian (DWAC) system its Pro Rata Share of such Interest Payment Shares determined pursuant to Section 6 of this Exhibit. Concurrently with the valid delivery of the related Interest Payment Shares on the applicable Interest Payment Date, an amount (the “Interest Credit Amount”) of interest payable on such Interest Payment Date equal to the product of (x) the number of Interest Payment Shares issued and delivered to a Lender on such date multiplied by (y) the applicable Interest Payment Share Price, shall be deemed to have been satisfied. (b) To the extent that the Borrower elects to satisfy principal in Freely Tradeable Shares pursuant to a Share Issuance Notice, for each Trading Day during the applicable Issuance Period (each, a “Reference Date”), the Borrower shall issue to each Lender such Lender’s Pro Rata Share of an aggregate number of shares of Common Stock (rounded to the nearest whole share, with 0.5 being rounded up) equal to the product of (x) the number of shares of Common Stock traded at or above the Floor Price (on all exchanges and quotation systems on which shares of Common Stock are cited as having been traded, per the Bloomberg AQR function) on such Reference Date between 9:35 a.m., New York City time, and 3:55 p.m., New York City time (the “Applicable Trading Period”), multiplied by (y) 0.19 (the “Daily Issuance Shares”); provided, that, at such time on any Reference Date as the value (as determined in accordance with this Section 4(b)) of all shares issuable in respect of such Reference Date (up to such time of such Reference Date) (the “Partial Reference Date Shares”) together with the value of all shares issued or issuable hereunder in respect of prior Reference Dates during such Issuance Period are sufficient to satisfy the entire principal portion of the Share Issuance Amount then the Daily Issuance Shares shall be equal to the Partial Reference Date Shares and such Issuance Period and the Applicable Trading Period shall thereafter be deemed terminated for all purposes hereunder. Within two hours following the close of regular trading hours on each Reference Date for which Daily Issuance Shares are issuable hereunder, the Lenders shall deliver a notice (a “Daily Share Notice”) to the Borrower setting forth the number of Daily Issuance Shares and the portion of the Share Issuance Amount to be satisfied on the Principal Share Issuance Closing Date (as defined below) related to such Reference Date, together with appropriate calculations of such amount. By no later than 5:30 p.m., New York City time, on the second Trading Day following each Reference Date (each, a “Principal Share Issuance Closing Date”), the Company shall deliver to each Lender its Pro Rata Share of the applicable Daily Issuance Shares by causing the Company’s transfer agent to electronically transmit such Daily Issuance Shares to each Lender by crediting to the account of each Lender’s prime broker (as specified by such Lender no later than one Trading Day prior to the applicable Principal Share Issuance Closing Date) with DTC through its Deposit/Withdrawal at Custodian (DWAC) system its Pro Rata Share of such Daily Issuance Shares. Concurrently with the valid delivery of the related Daily Issuance Shares on each Principal Share Issuance Closing Date, an amount (the “Principal Credit Amount”) equal to the product of (x) the number of shares of Common Stock issued and delivered to a Lender on such date multiplied by (y) 93% of the Volume Weighted Average Price for shares of Common Stock that trade at or above the Floor Price during the Applicable Trading Period (on all exchanges and quotation systems on which shares of Common Stock are cited as having been traded, per the Bloomberg AQR function) on Ex.2.3-5 141540134

the applicable Reference Date shall be applied to, and reduce, the principal amount being satisfied through the issuance of Common Stock, in each case, in accordance with Sections 2.3(e) of the Agreement. (c) All shares of Common Stock issued and delivered pursuant to this Section 4 shall be Freely Tradeable Shares (and for the avoidance of doubt, only Freely Tradeable Shares shall be deemed to constitute Interest Payment Shares or Daily Issuance Shares and be applied to any Credit Amount). In connection with the issuance and delivery of any shares of Common Stock to the Lenders pursuant to this Section 4, the Borrower shall deliver to the transfer agent for its Common Stock, by no later than (i) the last Business Day prior to the Interest Payment Date for which a Share Issuance Notice has been delivered to provide for the satisfaction of interest or (ii) the first Principal Share Issuance Closing Date for each Issuance Period in respect of a Share Issuance Notice delivered to provide for the satisfaction of principal, as applicable, an opinion of counsel reasonably satisfactory to the Lenders, substantially in the form attached as Annex 1 to this Exhibit, relating to all shares of Common Stock to be issued and delivered to the Lenders as Freely Tradeable Shares, and such other instructions, documents and instruments as may be reasonably required by such transfer agent in connection with the issuance to the Lenders of Freely Tradeable Shares on the Interest Payment Date or during such Issuance Period, as applicable. Copies of such instructions, documents and instruments shall be provided to the Lenders promptly upon a request therefor. 5. Limitations on Share Issuances. Notwithstanding anything herein to the contrary: (a)The Borrower shall not issue to any Lender, and no Lender may acquire, a number of shares of Common Stock hereunder to the extent that, upon such issuance, the number of shares of Common Stock then beneficially owned by such Lender and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with such Lender’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which the Lender is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities (including the Notes) that have limitations on the right to convert, exercise or acquire similar to the limitation set forth herein), would exceed 4.985% of the total number of shares of Common Stock then issued and outstanding (the “4.985% Cap”). For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the SEC, and the percentage held by each Lender shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. All Share Issuance Notices shall set forth the number of shares of Common Stock then outstanding. Upon written request of any Lender at any time, the Borrower shall, within one (1) Business Day, confirm orally and in writing to such Lender the number of shares of Common Stock then outstanding. At any time following delivery of a Share Issuance Notice and ending on the last Trading Day prior to the applicable Interest Payment Date or any applicable Principal Share Issuance Closing Date, each Lender shall have the right to deliver notice to the Borrower (a “Cap Notice”) (and, if applicable, shall be entitled to include such Cap Notice in a Daily Share Notice) stating the maximum number of shares of Common Stock that may be issued to such Lender without exceeding the maximum number of shares that such Lender may receive under the 4.985% Cap (the “Maximum Share Amount”), which shall be Ex.2.3-6 141540134

conclusive and binding upon the Borrower and such Lender. Notwithstanding anything herein to the contrary, in no event shall (i) the number of shares issued to a Lender pursuant to any Share Issuance Notice relating to interest or to a Lender on any Principal Share Issuance Closing Date exceed such Lender’s applicable Maximum Share Amount specified in such Lender’s Cap Notice; (ii) the aggregate number of shares issued to a Lender pursuant to any Share Issuance Notice, together with the shares previously issued to such Lender pursuant to Share Issuance Notices, exceed such Lender’s Share Issuance Limit; or (iii) any shares be issued to any Lender pursuant to a Share Issuance Notice relating to interest to the extent that all of the interest payment due on the applicable Interest Payment Dates have been otherwise satisfied or all Interest Payment Dates have occurred. For the avoidance of doubt, the Borrower shall not be entitled, or permitted, to issue an aggregate number of shares of Common Stock pursuant to this Exhibit 2.3 in excess of the Share Issuance Limit. (b) The Borrower shall not deliver more than one Share Issuance Notice on any day. Following the delivery of any Share Issuance Notice, from and after the delivery thereof, the Borrower shall not deliver a subsequent Share Issuance Notice until three (3) Trading Days following: (i) if the first such Share Issuance Notice provides for the satisfaction of interest through the issuance of Freely Tradeable Shares, the date all of the interest payable on the applicable Interest Payment Date shall have been satisfied in full and (ii) if the first such Share Issuance Notice provides for the satisfaction of principal through the issuance of Freely Tradeable Shares, the date that the Borrower shall have delivered a number of Freely Tradeable Shares equal to the Daily Issuance Shares for each Trading Day during the applicable Issuance Period and satisfied its obligation to pay (in cash) the Prepayment Fees and Make Whole Interest applicable to the principal repaid pursuant to such Share Issuance Notice. (c) Following the delivery of any Conversion Notice (as defined in the Notes) the Borrower shall not deliver a Share Issuance Notice that provides for the satisfaction of principal through the issuance of Freely Tradeable Shares until ten (10) Trading Days following the issuance of Conversion Shares pursuant to such Conversion Notice. (d) The Borrower shall not deliver a Share Issuance Notice that would result in any Issuance Period ending fewer than three (3) Trading Days prior to a date on which principal is due under Section 2.3(a) of the Purchase Agreement, except in connection with the 2019 Principal Payment so long as the Share Issuance Notice is delivered prior to the date the 2019 Principal Payment is due (the “2019 Principal Payment Date”). If the Borrower delivers a Share Issuance Notice prior to the 2019 Principal Payment Date and the Issuance Period with respect thereto shall not have ended prior to the 2019 Principal Payment Date, then for the 2019 Principal Payment Date and each calendar day thereafter, the difference between the Share Issuance Amount and the sum of the Principal Credit Amounts as of the end of each such day shall bear interest at the annual rate of 20%, compounded daily, and the Share Issuance Amount shall increase daily by the amount of such interest until the earlier of (i) such time as the sum of the Principal Credit Amounts equals the Share Issuance Amount as so increased and (ii) such time as the excess of the Share Issuance Amount, as so increased, over the sum of the Principal Credit Amounts has been paid by the Borrower to the Purchasers in cash. Notwithstanding anything to the contrary contained herein, if the Borrower delivers a Share Ex.2.3-7 141540134

Issuance Notice prior to the 2019 Principal Payment Date, then the Borrower shall not be obligated to pay an amount equal to the Share Issuance Amount on the 2019 Principal Payment Date, but (for the avoidance of doubt) the Borrower shall remain obligated to pay the portion of the 2019 Principal Payment in excess of the applicable Share Issuance Amount on the 2019 Principal Payment Date in accordance with the terms of the Facility Agreement. If, as of the end of the Issuance Period in respect of any such Share Issuance Notice, the Share Issuance Amount, as increased in accordance with this paragraph, exceeds the sum of the applicable Principal Credit Amounts for such Issuance Period, the Company shall pay such excess amount to the Lenders (ratably, based on their Pro Rata Shares), in cash by wire transfer of immediately available funds, on the first Business Day following the end of such Issuance Period. 6. Allocation Among Lenders. All shares of Common Stock issuable to the Lenders pursuant to this Exhibit, all Credit Amounts and all Failure Amounts shall be allocated pro rata among the Lenders based on each Lender’s Pro Rata Share. 7. Termination of Right to Issue Shares.

(“PharmaFab”), one of PhamaFab’s subsidiaries and two of Pharmafab’s officials (collectively, the “Defendants”).
