providers (comprising a subset of Egalet’s target health care provider list existing as of such date as described in Section 5.3.13 (such target list to include a number of health care providers per sales representative consistent with pharmaceutical industry practice)). For clarity, such sales representatives shall be permitted to detail any other products (other than a product that would violate the provisions of Section 9.1) during a Product Detail.

Egalet will be responsible for the activities of its sales representatives, including compliance by its sales representatives with training and Detailing requirements. For the avoidance of doubt, failure to achieve the required number of sales representatives as required by this Section 5.2.1 shall be deemed to be a material breach of a material obligation by Egalet, and Acura shall have its rights under Section 14.2 with respect to such breach;

5.2.2 Without limiting Sections 5.4.1 and 5.4.2, use Commercially Reasonable Efforts to Launch the Product in the United States, and in each Other Country in the Territory as soon as commercially practical after Regulatory Approval in such country, and to perform such obligations by using personnel with sufficient skills and experience, together with sufficient equipment and facilities. Notwithstanding the foregoing, Egalet shall not be deemed to have failed to perform the foregoing obligations, if it is using Commercially Reasonably Efforts, in the event one or more of the following events or circumstances (the “Commercialization Conditions”) occurs and such event or circumstance, or the material effect thereof, is continuing: [*****];

5.2.3 Egalet shall exercise Commercially Reasonable Efforts to commercialize the Product following Launch in the U.S. and such Other Countries;

5.2.4 not later than [*****] prior to the anticipated Launch of the Product in the United States, prepare an overview-marketing plan for the Product, which shall include plans related to the prelaunch, Launch, promotion and sale of the Product in the United States and which shall include forecasts for the number of sales representatives, and a reasonably descriptive overview of the marketing and advertising campaigns, including related budgets, proposed to be conducted (each, a “Marketing Plan”). Thereafter, each Marketing Plan shall be updated by Egalet, in accordance with Egalet’s usual marketing operations planning cycles, but in no case less than once each Commercial Year during the Term. Egalet shall provide copies of the Marketing Plan to the JSC for review and comment as soon as practicable following preparation. If Acura exercises its Co-Promotion Right pursuant to Section 5.3, Egalet promptly shall update, through the JSC, the Marketing Plan to reflect Acura’s Co-Promotion Right in a manner that is consistent with Section 5.3 and which does not materially disadvantage Acura in relation to the exercise of its Co-Promotion Right. If Acura should dispute whether the Marketing Plan complies with the requirements of the immediately preceding sentence, such dispute shall be settled in accordance with the Special Arbitration Provisions of Section 16.3; and

5.2.5 maintain records in accordance with Egalet’s usual business practices of the work done and results achieved in connection with the Commercialization Program and as may be required under all Applicable Laws.

5.3 Acura’s Co-Promotion Rights.

5.3.1 Subject to the terms of this Section 5.3, Acura shall have the non-sublicensable, non-transferable (except in connection with an assignment of this Agreement pursuant to Section 17.2) right to co-promote the Product (including Product Line Extensions) in the United States (the “Co-Promotion Right”).

From and after the sixtieth (60th) day after the Co-Promote Notice, Acura shall commence co-promotion of the Product in accordance with this Section 5.3.

5.3.4 Acura may cease the co-promotion of the Product at any time on sixty (60) days’ written notice to Egalet, and the Co-Promotion Right shall terminate on the sixtieth (60th) day after such notice; provided, however, that if (i) Egalet exercises its right under Section 5.3.13 to add Acura target health care providers to Egalet’s list of target health care providers, and (ii) Acura’s notice of cessation of its Co-Promotion Right specifies Egalet’s exercise of its right under Section 5.3.13 as the cause of Acura’s cessation, which notice of cessation must be provided within thirty (30) days after the later of (i) Egalet’s exercise of such right under Section 5.3.13, and (ii) the resolution of any dispute relating to Egalet’s exercise of such right under Section 5.3.13 as provided for in such section and Section 16.3, then Acura may, at any time upon sixty (60) days’ prior written notice to Egalet resume the co-promotion of the Product, including establishing its list of target health care providers in accordance with Section 5.3.13. Except as provided in this Section 5.3.4, after termination of the Co-Promotion Right, Acura shall not have

any further rights to co-promote the Product nor to subsequently exercise the Co-Promotion Right.

5.3.5 Following Acura’s exercise of the Co-Promotion Right, Acura will be entitled to receive, and Egalet shall remit to Acura within forty five (45) days (or if later, within thirty (30) days following Acura’s provision to Egalet of Acura’s Detail report described in Section 5.3.9) after each Calendar Quarter commencing with the Calendar Quarter following the Co-Promote Notice, [*****]. “Incremental Net Sales” shall mean [*****]. “Gross Margin” shall mean [*****]. Acura’s receipt of the Gross Margin payment described above (“Co-Promotion Payment”) will be in lieu of the royalty payments otherwise payable to Acura under the Agreement calculated based on Incremental Net Sales resulting from prescriptions written by the health care providers contained in Acura’s list provided to Egalet pursuant to Section 5.3.13. Co-Promotion Payments in respect of a Calendar Quarter shall be paid within forty-five (45) days; (or if later, within thirty (30) days following Acura’s provision to Egalet of Acura’s Detail report described in Section 5.3.9) after the end of such Calendar Quarter. For clarity, Acura will not be entitled to a Co-Promotion Payment in respect of any prescriptions written by health care providers that are not Acura’s list provided to Egalet pursuant to Section 5.3.13, even if Acura has Detailed such providers. Notwithstanding the foregoing, Egalet shall be responsible for all distribution activities relating to the Product.

5.3.6 Acura may perform some or all of its co-promotion through a CSO reasonably acceptable to Egalet, at Acura’s sole cost and expense. Acura will be solely responsible for recruiting, hiring and maintaining its sales force of sales representatives for promotion of the Product in accordance with its standard procedures and the requirements of this Agreement. Acura agrees that any of its sales representatives involved in the promotion of the Product will not have any legal or regulatory disqualifications, bars or sanctions. Acura will be responsible for the activities of its sales representatives, including compliance by its sales representatives with training and Detailing requirements. In particular, Acura will provide its sales representatives assigned to promote the Product with the level of oversight, management, direction and sales support with respect to the promotion of Product reasonably necessary to effectively and efficiently promote the Product in accordance with the terms of this Agreement and Applicable Law. If Egalet raises any concern with Acura regarding the performance or fitness of any Acura sales representative, Acura will consider Egalet’s comments and recommendations in good faith. For clarity, Acura’s implementation or non-implementation of Egalet’s comments and recommendations shall not relieve Acura of any responsibility for breach of any of its obligations hereunder with respect to the performance or fitness of any Acura sales representative.

5.3.7 Acura will train its sales force consistent with Egalet training requirements and Egalet sales force policies. In connection therewith, within thirty (30) days after receipt of the Co-Promote Notice, Egalet, upon Acura’s request shall provide training materials to, and hold in-person meetings or webcasts for, each member of Acura’s sales force prior to his or her commencement of promotion of the Product to ensure that he or she is appropriately trained in proper detailing and sales techniques. On an ongoing basis [*****], at Acura’s request and upon reasonable prior notice, Egalet shall provide training materials to, and hold in-person meetings or webcasts for, each member of Acura’s sales force as necessary to provide training (in the case of

new hires), refresher training and training updates. The Parties shall use good faith efforts to coordinate the timing of, and attendance at, any such trainings so that such training is provided to reasonably sized groups consistent with industry standards. Acura shall bear (i) the costs of training materials, (ii) Egalet’s out-of-pocket costs relating to such training, and (iii) Egalet’s internal costs for salaries and benefits for its personnel who provide training, refresher training and training updates to Acura; provided that Acura shall not be responsible for Egalet’s costs pursuant to this subsection (iii) where such training also includes Egalet’s sales representatives.

5.3.8 Acura will adhere to the Marketing Plan, provided such Marketing Plan conforms to the requirements of this Agreement.

5.3.9 Acura will, at its cost and expense, maintain records and otherwise establish procedures to ensure compliance with all Applicable Laws and professional requirements that apply to its promotion and marketing of the Product, including compliance with the PhRMA Code on Interactions with Healthcare Professionals. Acura will provide Egalet with copies of any such records promptly upon Egalet’s request. Further, Acura will prepare and provide to Egalet, at no cost or expense to Egalet, such reports regarding its activities under this Section 5.3 as Egalet may reasonably require, including in order to comply with reporting requirement under the Sunshine Act (5 U.S.C. § 552b). In addition, Acura will provide Egalet with a report, as soon as practicable and with a target delivery date of [*****] following the end of each Calendar Quarter, setting forth in reasonable detail the Details made by its sales representatives of the Product during such Calendar Quarter.

5.3.10 Acura will only use promotional materials and detailing scripts provided and approved by Egalet, and Egalet shall provide copies requested by Acura of all such sales material and detailing scripts to Acura for promotion of the Product at Acura’s expense for such copies, provided that all other production costs (such as developing such marketing materials and detailing scripts) shall be borne by Egalet. For clarity, Egalet shall not be required to develop any promotional materials or detailing scripts specifically for Acura. Acura will instruct its sales representatives to make only those statements and claims regarding the Product, including as to efficacy and safety, that are consistent with the Product labeling and accompanying inserts and the approved promotional materials and detailing scripts.

5.3.11 Acura’s sales force must be at least [*****] or full-time equivalents thereof within [*****], provided that such sales representatives may also market any other products (other than a product that would violate the provisions of Section 9.2). Such sales force will provide [*****] co-promotion of the Product as agreed to by the Parties, provided that in the absence of such agreement the Acura sales force will co-promote the Product [*****].

5.3.12 Egalet will be solely responsible for the execution of Medical Affairs, after the transfer of such responsibility as set forth in Section 11.5.

5.3.13 At the time provided in Section 5.3.2, and within [*****] following each Calendar Quarter during the period Acura is co-promoting the Product pursuant to Section 5.3, Egalet will provide Acura a list of target health care providers to which Egalet (and its Affiliates and sublicensees) is then Detailing the Product or to which it then intends to Detail the Product.

In its Co-Promote Notice, Acura shall provide to Egalet a list of health care providers to which it intends to Detail the Product, which shall not (i) overlap with those health care providers on Egalet’s then-current list (including any health care providers within the same group or department practice at the same location as a health care provider on Egalet’s then-current list) and (ii) include any managed care organizations or pharmacies.

5.3.13.1 Thereafter, Acura may, from time-to-time, change its list of target health care providers, provided any such target health care provider is not (i) on Egalet’s then-current list (including any health care providers within the same group or department practice at the same location as a health care provider on Egalet’s then-current list) and (ii) a managed care organization or pharmacy. Acura shall provide Egalet with [*****] prior written notice of any addition of health care providers to its then-current list, and in any event will provide within [*****] days following each Calendar Quarter during the period Acura is co-promoting the Product pursuant to Section 5.3, a then-current list of target health care providers to which Acura is then Detailing the Product or to which it then intends to Detail the Product, provided any such target health care provider is not (x) on Egalet’s then-current list (including any health care providers within the same group or department practice at the same location as a health care provider on Egalet’s then-current list) and (y) a managed care organization or pharmacy. Acura shall not Detail the Product to a health care provider not on its then-current list, without the consent of Egalet.

5.3.13.2 Egalet (and its Affiliates and sublicensees) may Detail any health care providers that are not on Acura’s then-current list (other than health care providers within the same group practice at the same location as a health care provider on Acura’s then-current list), even if such health care providers are not on Egalet’s then-current list.

5.3.13.3 Neither Party shall Detail the Product to a health care provider on the other Party’s list, without the consent of the other Party. Notwithstanding the foregoing, Egalet may, [*****], request the JSC to approve territory realignment by submitting to the JSC a new list of Egalet target health care providers, which list may contain overlapping target health care providers on Acura’s then-current list, not to exceed an amount equal to [*****] of those health care providers contained on Acura’s then-current list of targeted health care providers, provided that if at such time Acura’s sales force Detailing the Product exceeds [*****] sales representatives, then Egalet’s new list of target health care providers may contain overlapping target health care providers on Acura’s then-current list in an amount up to and including [*****] of those health care providers contained on Acura’s then-current list of targeted health care providers. For such overlapping target health care providers, the JSC will determine in good faith whether it reasonably believes the Egalet field sales representatives can materially improve Product prescribing from an overlapping target health care provider and, if so, Egalet shall be entitled to have such target health care provider on its list; provided however, that if Acura files a notice of dispute with the JSC within ten (10) days of its determination, Acura will be entitled to receive the Co-Promotion Payment (as calculated pursuant to Section 5.3.5) derived from such overlapping health care provider that are contested in Acura’s dispute notice for [*****] following the date of Acura’s notice of dispute, provided that with respect to those health care providers that Acura has not detailed within the [*****], Acura will be entitled to receive the Co-Promotion Payment (as calculated pursuant to Section 5.3.5) derived from such

overlapping health care provider for only the [*****] following the date of Acura’s notice of dispute, and provided further that in the case where Acura’s sales force Detailing the Product exceeds [*****] sales representatives, no such determination from the JSC will be required in order for Egalet to include such overlapping health care providers (capped at [*****]) on its list but Acura will automatically be entitled to receive the Co-Promotion Payment for the [*****] as provided in the immediately preceding proviso. No Party shall include a health care provider on its respective list unless it has Detailed the Product to such health care provider [*****] or in good faith intends to Detail the Product to such heath care provider [*****] following the provision of the list.

5.3.14 Acura’s Co-Promotion Right shall terminate thirty (30) days after the first commercial sale of a Generic Equivalent in the United States.

5.3.15 Egalet may terminate Acura’s Co-Promotion Right, without prejudice to any other remedies available to it at law or in equity, in the event Acura shall have materially breached or defaulted in the performance of any of its material obligations under this Section 5.3 and such breach or default shall have continued for sixty (60) days after written notice thereof was provided to Acura by Egalet. Any such termination under this Section 5.3.15 shall become effective at the end of such sixty (60) day period unless Acura has cured any such noticed breach(es) or default(s) prior to the expiration of such sixty (60) day period.

5.3.16 Acura’s Co-Promotion Rights under this Section 5 shall remain in full force and effect regardless of a Change of Control of Acura or any assignment or transfer of this Agreement to a Third Party, provided, however, they shall be suspended [*****] following a Change of Control transaction or any assignment or transfer of this Agreement to a Third Party, if the acquiror in such Change of Control transaction, or the assignee or transferee of this Agreement, as applicable, is marketing a pharmaceutical product in, or is conducting or has conducted [*****], the United States which is or would be in direct competition with a pharmaceutical product being marketed by Egalet in the United States at the time of such Change of Control transaction or assignment or transfer of this Agreement, as applicable, until such acquiror or assignee or transferee, as applicable, divests such competing product. If such acquiror, assignee or transferee does not divest such competing product within [*****] of the closing of such Change of Control transaction or assignment or transfer of this Agreement, as applicable, Acura’s Co-Promotion Right shall terminate. For purposes of this Section 5.3.16, a pharmaceutical product shall be deemed in direct competition with a pharmaceutical product being marketed by Egalet or its Affiliates in the United States if it is [*****].

5.4 Product Launch Diligence.

5.4.1 Egalet shall use Commercially Reasonable Efforts to Launch the Product in the United States as soon as commercially practical following the Effective Date and with respect to Other Countries, as provided in Section 5.4.2. Notwithstanding the foregoing, Egalet shall not be deemed to have failed to perform the foregoing obligations, if it is using its Commercially Reasonably Efforts, in the event one or more Commercialization Conditions have occurred and is continuing or the material effect of such Commercialization Condition is continuing. In any event, Egalet must Launch the Product in the United States by [*****],

provided that if one or more Commercialization Conditions has occurred and the material effect of such Commercialization Condition(s) is continuing and has an adverse effect on Egalet’s ability to Launch by such date, Egalet may delay the Launch beyond such date; and if the Launch does not occur by [*****] due to any Commercialization Condition, then Egalet shall Launch the Product not later than [*****] following the date such Commercialization Condition or material effect shall have been substantially remedied or abated (the “Required Launch Date”). Egalet shall order Launch Quantities from the Contract Manufacturer with sufficient lead time (giving effect to any intervening Commercialization Condition and Egalet’s reasonable assessment of the timing of remedy or abatement of such Commercialization Condition) so that such quantities are received in advance of the Required Launch Date.

5.4.2 Egalet shall use Commercially Reasonable Efforts to Launch the Product in any Other Country in the Territory as soon as commercially practical after receipt of Regulatory Approval for the Product in such country, provided that no Commercialization Condition has occurred and is continuing or the material effect of such Commercialization Condition is continuing; and if a Commercialization Condition or the material effect thereof delays such Launch, then Egalet shall Launch the Product as soon as reasonably practical following the date such Commercialization Condition or material effect shall have been remedied or abated.

5.4.3 For the avoidance of doubt, failure to satisfy its obligations pursuant to Sections 5.4.1 shall be deemed to be a material breach of a material obligation by Egalet, and Acura shall have its rights under Section 14.2 to terminate this Agreement with respect to such country with respect to such breach.

5.5 Parties’ Responsibilities in Support of Commercialization.

5.5.1 Regulatory Filings. Each Party shall provide or otherwise make available to the other Party upon reasonable request complete copies of any material regulatory filings relating to the Product (including any Product Line Extensions) in the Territory, including Regulatory Approval Applications, material filings with the FDA, including, without limitation, material supplements or amendments thereto, all written material correspondence with the FDA regarding such regulatory filings, and all existing written minutes of material meetings and memoranda of material conversations between it (including, to the extent practicable, its investigators) and the FDA in its possession (or in the possession of any of its agents and subcontractors, such as contract research organizations used by it). The requesting Party shall reimburse the providing Party for its out-of-pocket expenses in connection with the provision of materials pursuant to this Section 5.5.1.

5.6 Non-Solicitation.

5.6.1 During the Term and for [*****] period thereafter, Acura and its Affiliates shall not hire, solicit for hire, or otherwise engage for employment (or the provisions of services under contract) any sales representative employed (whether as an employee or third party contractor) by Egalet or any of its Affiliates or any sales force representative that was employed

by Egalet or any of its Affiliates at any time during the [*****] period preceding such hiring, solicitation, or recruitment.

5.6.2 During the Term and for [*****] period thereafter, Egalet and its Affiliates shall not hire, solicit for hire, or otherwise engage for employment (or the provisions of services under contract) any sales representative employed by Acura or any of its Affiliates or any sales force representative that was employed (whether as an employee or third party contractor) by Acura or any of its Affiliates at any time during the [*****] period preceding such hiring, solicitation, or recruitment.

6. MILESTONE AND ROYALTY PAYMENTS

As partial consideration for the rights granted to Egalet hereunder, Egalet shall make the following payments to Acura:

6.1 Upfront Payment. Within ten (10) days after the Effective Date, Egalet shall make a non-refundable, non-creditable payment to Acura of Five Million Dollars ($5,000,000), in immediately available funds by wire transfer (the “Upfront Payment”), with [*****].

6.2 Additional Payment. Within ten (10) days after the later of (a) the First Commercial Sale of the Product by Egalet and (b) June 30, 2015, but in the case of each of subsections (a) and (b), in any event not later than January 1, 2016, Egalet shall make a non-refundable, non-creditable payment to Acura of Two and One-Half Million Dollars ($2,500,000), in immediately available funds by wire transfer, with [*****].

6.3 Sales Milestone Payment. Within thirty (30) days after the end of the first calendar year in which worldwide Net Sales of the Product (including any Product Line Extensions and including any Incremental Net Sales generated by Acura’s Co-Promotion activities (but excluding Net Sales generated in a country where the Royalty Term has expired or been terminated, after the later of (i) such expiration or termination and (ii) any inventory sell-off by Egalet under Section 14.9)) reach $150 million during such calendar year, Egalet shall make a non-refundable, non-creditable payment to Acura of twelve and one-half million dollars ($12,500,000), in immediately available funds by wire transfer (the “Sales Milestone Payment”), with [*****].

6.4 Royalties.

6.4.1 As partial consideration to Acura for the license rights, and other rights granted to Egalet under this Agreement, during the Term, Egalet shall pay to Acura a royalty based on calendar year Net Sales of the Product in the Territory by Egalet, its Affiliates and permitted sublicensees during each calendar year according to the following table:

Royalty Rate:	Portion of Worldwide Calendar Year Net Sales of the Product Greater Than:	Portion of Worldwide Calendar Year Net Sales of the Product Up to But Not Exceeding:
[*]	[*]	[*]
[*]	[*]	[*]
[*]	[*]	[*****]
[*]	[*]	[*]

In calculating worldwide calendar year Net Sales, the Net Sales in a country whose Royalty Term has expired or terminated shall be excluded, but only for the period following the later of (i) such expiration or termination and (ii) any inventory sell-off by Egalet under Section 14.9. Royalties for Net Sales of the Product in a country in the Territory shall be payable only during the Royalty Term in such country.

Notwithstanding the foregoing, in a calendar year in which aggregate Net Sales of the Product in the Territory achieves or exceeds [*****], the royalty rate will be [*****] on all Net Sales in that calendar year. Egalet shall undertake a royalty true-up during the Calendar Quarter in which calendar year Net Sales first exceed [*****]. Royalties shall be recalculated for all Net Sales for all prior Calendar Quarters during such calendar year, as if the [*****] royalty rate had been applicable from the first dollar of Net Sales for such calendar year. The difference between such recalculated royalties and those actually paid to Acura for prior Calendar Quarters is referred to as the “Royalty True-Up.”

For purposes of this Section 6.4, Net Sales shall exclude the Incremental Net Sales used in the calculation of Acura’s Co-Promotion Payments under Section 5.3.5.

6.4.2 If, with respect to the Product being sold in a country in the Territory in a particular Calendar Quarter, there are sales of a single Generic Equivalent of the Product (considering all strengths of such Generic Equivalent as one Generic Equivalent) in such country during such Calendar Quarter, then the Net Sales of the Product for such country in such Calendar Quarter, used for calculating the royalties owed to Acura for such Net Sales, shall be reduced by [*****].

6.4.3 If, with respect to the Product being sold in a country in the Territory in a particular Calendar Quarter, there are sales of two or more Generic Equivalents of the Product (counting all strengths of a particular Generic Equivalent as one Generic Equivalent) in such country during such Calendar Quarter, then the Net Sales of the Product for such country in such Calendar Quarter, used for calculating the royalties owed to Acura for such Net Sales, shall be reduced by [*****].

6.5 Co-Promotion Payments. Egalet shall remit to Acura the Co-Promotion Payments provided in Section 5.3.5 at the times specified in such section.

6.6 Reduction of Payments for Royalty Stacking. Royalties and Co-Promotion Payments payable to Acura shall be subject to reduction as set forth in Section 10.7.

6.7 Royalty Payments. Within forty five (45) days following the end of each Calendar Quarter (or if later, with respect to Co-Promotion Payments, within thirty (30) days following Acura’s provision to Egalet of Acura’s Detail report described in Section 5.3.9),

beginning with the Calendar Quarter in which the First Commercial Sale of the Product is made in the Territory, and for each Calendar Quarter thereafter, Egalet will pay to Acura the royalty payments calculated pursuant to Sections 6.4, 6.5 and 6.6 and the applicable Royalty True-Up, if any. Each royalty payment and Co-Promotion Payment shall be accompanied by a report, substantially in the form as attached hereto in Exhibit 6.7, summarizing (a) (i) the total gross sales of the Product(s), on a dosage-by-dosage, country-by-country basis, (ii) total Net Sales for each Product (including an itemization of the deductions applied to such gross sales to derive such Net Sales) during the relevant Calendar Quarter, (iii) the calculation of royalties due thereon, and (iv) the Royalty True-up, if any, and (b) if the Co-Promotion Right has been exercised by Acura, (i) the calculation of the Co-Promotion Payment (including the AMP and an itemization of all items used to calculate the Co-Promotion Payment), (ii) the total number of prescriptions for the Product filled in such Calendar Quarter, (iii) the average number of tablets per Rx, and (iv) the average Cost of Goods Sold for each dosage strength of the Product. In the event that no royalty payments or Co-Promotion Payments are payable in respect of a given Calendar Quarter, Egalet shall submit a report so indicating.

6.8 Mode of Payment; Currency Conversion. All payments required under this Agreement shall be made in U.S. dollars, regardless of the country(ies) in which sales are made or expenses are incurred, via wire transfer of immediately available funds as directed by the Party entitled to such payment from time to time. Whenever, for the purpose of calculating any sums due under this Agreement, conversion from any foreign currency shall be required, such conversion shall be made as follows: the amounts shall be converted into United States dollars using the average rate of exchange for such currencies for the relevant period, such exchange rate shall be the mid-price exchange rate taken from The Wall Street Journal as published on the last day of the relevant period for which payments are due, or such other publication as may be agreed between the Parties from time to time. All amounts payable under this Agreement and not paid when due in accordance with the provisions hereof shall bear interest from the due date until paid at the rate equal to the lesser of [*****], and (ii) the maximum interest rate permitted by Applicable Law.

6.9 Inventory Purchase. Acura shall test the items listed on Exhibit 6.9 at Acura’s cost in accordance with Egalet’s standard operating procedures for its viability for use in manufacturing the Product and shall provide Egalet with the results of such testing in writing. If such testing confirms that such items meet the specifications for such materials, Egalet shall purchase such API and packaging inventory, as listed on Exhibit 6.9, from Acura at Acura’s cost (as specified in such Exhibit). [*****] Prior to use of the API comprising a portion of the purchased inventory, Egalet shall conduct such testing as it shall determine reasonably necessary to confirm such API meets applicable specifications. If the API fails to meet applicable specifications, Egalet shall return such non-conforming API to Acura and Acura shall refund to Egalet all amounts paid therefor, including shipping costs. To the extent Egalet, its Affiliates or its Contract Manufacturer, have been unable to use the purchased inventory in the Manufacture of the Product within [*****] following the Launch of the Product, Egalet may return such remaining purchased inventory to Acura for a refund (determined based on the unit costs provided in Exhibit 6.9).

6.10 Records Retention. Commencing with the Launch of the Product, (i) Egalet shall keep complete and accurate records pertaining to the sale of Product for a period of [*****] after the year in which such sales occurred, and in sufficient detail to permit Acura to confirm the accuracy of the royalties, Co-Promotion Payments and other amounts paid by Egalet hereunder, and any amounts for which Egalet has invoiced Acura and (ii) Acura shall keep complete and accurate records relating to its co-promotion of the Product (including Details performed) in sufficient detail to permit Egalet to confirm the Co-Promotion Payments paid or payable to Acura, and relating to any amounts for which it has invoiced Egalet.

6.11 Audits. At the request and expense of either Party (“Auditing Party”), the other Party (“Audited Party”) shall permit an independent, certified public accountant appointed by the Auditing Party and reasonably acceptable to the Audited Party, at reasonable times and upon reasonable written notice, but not more than once per calendar year, to examine such records as may be necessary for the sole purpose of verifying the calculation and reporting of Net Sales and Co-Promotion Payments and the correctness of any royalty or other payment made under this Agreement (including, without limitation, with respect to Infringement Actions, the Required Post-Marketing Study, and any expense sharing) or compliance with its commercialization requirements or co-promotion requirements for any period within the preceding [*****]. All results of any such examination shall be made available to the Audited Party. In the event that any audit reveals an under-payment in the amount of royalties, Co-Promotion Payments or other payment obligation that should have been paid by the Audited Party to the other, then the underpayment amount shall be paid within thirty (30) days after Auditing Party makes a demand therefore, plus interest thereon if such amount is in excess of [*****] of the amount that actually should have been paid. Such interest shall be calculated from the date such amount was due until the date such amount is actually paid, at the rate of [*****] for the date such amount was due. In addition, if the underpayment is in excess of [*****] of the amount that actually should have been paid [*****], then the Audited Party shall reimburse the Auditing Party for the reasonable cost of such audit.

6.12 Taxes. In the event that a Party is mandated under the laws of a country to withhold any tax to the tax or revenue authorities in such country in connection with any payment to the other Party, such amount shall be deducted from the payment to be made by such withholding Party, provided, however, that the withholding Party shall take reasonable and lawful actions, at the other Party’s sole cost, to avoid and minimize such withholding and promptly notify the other Party so that the other Party may take lawful actions to avoid and minimize such withholding. The withholding Party shall promptly furnish the other Party with copies of any tax certificate or other documentation evidencing such withholding as necessary to satisfy the requirements of the United States Internal Revenue Service related to any application by such other Party for foreign tax credit for such payment. Each Party agrees to cooperate with the other Party in claiming exemptions from such deductions or withholdings under any agreement or treaty from time to time in effect. Notwithstanding the foregoing, if Egalet is required to withhold or deduct any taxes by any government outside the United States, any subdivision thereof, or any other governmental unit within the territory of such government (such taxes collectively referred to as “Charges”), or Acura is required to pay any Charge imposed by any government outside the United States solely as a result of being a party to this Agreement, with respect to any amount payable to Acura under this Agreement, (in each case other than

amounts with respect to Net Sales outside the United States) Egalet shall pay such additional amounts so that payments received by Acura net of all Charges, shall equal the amount to which Acura would have been entitled had there been no such Charges, provided, however that Egalet shall have no obligation to pay any additional amount to the extent that the Charges are imposed by reason of Acura (A) not being a resident of the United States for tax purposes or (B) failing to provide a form or similar other evidence reasonably requested by Egalet that would allow for a reduction or exemption of such Charges that Acura is legally able to provide (including, for the avoidance of doubt, Acura’s qualification for the benefit of an applicable income tax convention). In addition, if Acura or its Affiliates is required to, or deems it advisable to file tax returns or make other filings with respect to Charges in any jurisdiction outside the United States by virtue of Egalet UK or another non-US Affiliate of Egalet making payments to Acura hereunder (other than with respect to royalties for Net Sales arising outside the United States), Egalet will reimburse Acura for the reasonable out-of-pocket cost of preparation and filing such tax returns or other filings. Egalet represents and warrants that no withholdings for taxes are required to be made on payments to Acura for milestones or royalties (for sales in the United States) described in this Agreement, Co-Promotion Payments or payments under Section 6.1 and 6.2 under currently applicable law so long as Acura is a resident of the United States for tax purposes.

6.13 Bundling Prohibited. The Product may not be sold in any bundled transaction with any other products or any service by Egalet or its Affiliates or permitted sublicensees (or by Acura or its Affiliates and sublicensees in exercising its Co-Promotion Rights) unless a reasonable pro-rated allocation of the payments received in such bundled transaction is attributable to the Products contained in the bundle.

6.14 Invoicing and Payment of Shared Expenses.

(a) For all expenses that are to be shared by Parties pursuant to the express terms of this Agreement, the Party incurring such expense shall invoice the other Party for its Expense Split Percentage of such expense, and shall provide such other supporting details as the other Party shall reasonably request. All such invoices shall be payable within thirty (30) days from the date of receipt of such invoice and supporting materials. For the avoidance of doubt, expenses not explicitly designated as subject to the Expense Split Percentage in this Agreement shall be borne in their entirety by the responsible Party.

(b) In the event that the proposed budget for Product Line Extension Studies (determined as a group) or the proposed budget for Required Post-Marketing Studies (determined as a group) exceeds [*****] and Acura withholds its consent under Section 3.2.11, or does not provide its agreement within the ten (10) business day period specified in Section 3.2.11, Egalet may elect in its sole discretion to approve such budget, provided that (i) Acura shall be responsible for paying its Expense Split Percentage of such expenses only up to such [*****], (ii) Egalet shall be responsible for one hundred percent (100%) of such expenses exceeding [*****], and (iii) Egalet shall be entitled to apply as a credit against any royalty payments, Co-Promotion Payments and milestone

payments owed to Acura an amount equal to [*****] percent [*****] of Acura’s Expense Split Percentage of such expenses exceeding [*****].

Subject to compliance with the Litigation Condition, the Indemnifying Party shall retain counsel reasonably acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld or delayed) to represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party.

The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), effect any settlement of any pending or threatened proceeding in which the Indemnified Party is, or based on the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on claims that are the subject matter of such proceeding and will not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnified Party in any manner. Notwithstanding the foregoing, Acura’s consent (which shall not be unreasonably withheld, delayed or conditioned) shall be required for any settlement that entails any license, covenant not to ▇▇▇ relating to, admission of invalidity or unenforceability or abandonment of any of Acura’s intellectual property, including the Aversion Technology, and Egalet’s consent (which shall not be unreasonably withheld, delayed or conditioned) shall be required for any settlement that entails any license or covenant not to ▇▇▇ with respect to any Third Party Infringement related to a Paragraph IV Certification with respect to the Product or that would otherwise grant any rights to manufacture, use, sell or otherwise commercialize [*****] or admission of invalidity or unenforceability or abandonment of any Product-specific Intellectual Property. If the Litigation Condition is not met, then the Indemnified Party shall have the right to control the defense of such Third Party Claim, for which the Indemnifying Party shall pay the reasonable fees and costs incurred by the Indemnified Party, and the Parties shall cooperate in and be consulted on the material aspects of such defense at the Indemnifying Party’s expense; provided that if the Indemnifying Party does

not satisfy the Litigation Condition, the Indemnifying Party may at any subsequent time during the pendency of the relevant Third Party Claim irrevocably elect, if permitted by local procedural rules or laws, to defend and/or to control the defense of the relevant Third Party Claim at its sole cost and expense and so long as the Indemnifying Party also agrees to pay the reasonable fees and costs incurred by the Indemnified Party in relation to the defense of such Third Party Claim from the inception of the Third Party Claim until the date the Indemnifying Party assumes the defense or control thereof.

13.6 Assumption of Defense. Notwithstanding anything to the contrary contained herein, an Indemnified Party shall be entitled to assume the defense of any Third Party Claim with respect to the Indemnified Party, upon written notice to the Indemnifying Party pursuant to this Section 13.7, in which case the Indemnifying Party shall be relieved of liability under Section 13.1 or Section 13.2, as applicable, solely for such Third Party Claim and related Losses.

13.7 Insurance. During the Term and for [*****] thereafter, each Party shall maintain insurance with reputable and credit worthy insurance companies, in such amounts and against such risks as are usually maintained by comparable U.S. publicly registered companies engaged in the pharmaceutical business.

In the event a Party desire to self insure, in whole or in part, it shall obtain the prior written consent of the other Party, not unreasonably withheld or delayed.

13.8 No Set-off. Except as expressly set forth in this Agreement, neither Party may set-off or recoup against a payment owed to the other Party, without the consent of the other Party, other than any amounts payable to the first Party by such other Party as determined in a final judgment.

The Party giving such notice shall be excused from the performance, or the punctual performance, of such obligations, as the case may be, from the date of such notice, up to a maximum of one hundred eighty (180) days, after which time the Party not affected, may terminate this Agreement upon written notice to the affected Party if the failure in performance constitutes a material breach of this Agreement. To the extent possible, each Party shall use reasonable diligent efforts to avoid or minimize the duration of any Force Majeure.

16. DISPUTE RESOLUTION

16.1 Referral to Executive Officers. The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to a Party’s rights and/or obligations hereunder. If the Parties cannot resolve any such dispute within fifteen (15) calendar days after notice of a dispute from one Party to another, any Party may, by notice to the other Party, have such dispute referred to the Executive Officers. The Executive Officers shall meet promptly to negotiate in good faith the matter referred and to determine a resolution. During such period of negotiations, any applicable time periods under this Agreement shall be tolled. If the Executive Officers are unable to determine a resolution in a timely manner, which shall in no case be more than thirty (30) days after the matter was referred to them (or ten (10) days after referral if regarding a dispute arising out of or relating to Sections 3.2.6, 3.2.11, 5.2.4 or 5.3.13), the matter may be resolved through arbitration in accordance with the arbitration provisions set forth in Section 16.2 or Section 16.3, as applicable, upon notice by a Party on the other Party specifically requesting such arbitration.

16.2 Arbitration. Where a Party has served a written notice upon another requesting arbitration of a dispute pursuant to this Section 16.2, any such arbitration shall be submitted to final and binding arbitration under the then current commercial arbitration rules of the American Arbitration Association (the “AAA”) in accordance with this Section 16.2. The place of arbitration of any dispute shall be New York, New York. Such arbitration shall be conducted by one (1) arbitrator mutually agreed by the Parties but if such agreement cannot be reached within ten (10) days of the commencement of the arbitration, then an arbitrator appointed by the AAA.

The arbitrator shall be a person with relevant experience in the pharmaceutical industry. The arbitration proceeding shall be held as soon as practicable but in any event within ninety (90) days of appointment of the arbitrator. Any award rendered by the arbitrators shall be final and binding upon the Parties. Judgment upon any award rendered may be entered in any court having jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement, as the case may be. The arbitrator shall render a formal, binding, non-appealable resolution and award as expeditiously as possible, but not more than thirty (30) days after the hearing. Each Party shall pay its own expenses of arbitration, and the expenses of the arbitrator shall be equally shared between the Parties unless the arbitrators assess as part of their award all or any part of the arbitration expenses of a Party (including reasonable attorneys’ fees) against the other Party. A Party may make application to the Arbitrator for the award and recovery of its fees and expenses (including reasonable attorneys’ fees). This Section 16.2, shall not prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event of a breach or prospective breach of this Agreement by any other Party which would cause irreparable harm to the first Party.

16.3 Special Arbitration Provisions. In the event of a dispute arising out of or relating to Sections 3.2.6, 3.2.11, 5.2.4, or 5.3.13, which dispute remains unresolved after referral to the Executive Officers, then such dispute shall be finally settled by arbitration under the then current expedited procedures applicable to the then current commercial arbitration rules of the AAA in accordance with the following terms:

16.3.1 Upon written request by either Party to the other Party, the Parties shall promptly negotiate in good faith to appoint a mutually acceptable independent person, with scientific, technical and regulatory experience with respect to the development or commercialization of the Product necessary to resolve such dispute (an “Expert”). If the Parties are not able to agree within five (5) business days after the receipt by a Party of the written request in the immediately preceding sentence, the AAA shall be responsible for selecting an Expert within ten (10) business days of being approached by a Party. The fees and costs of the Expert and the American Arbitration Association, if applicable, shall be shared equally by the Parties. The place of arbitration of any dispute shall be New York, New York, unless the Parties agree otherwise or the selection of the Expert requires otherwise.

16.3.2 Within five (5) business days after the designation of the Expert, the Parties shall each simultaneously submit to the Expert and the other Party a written statement of their respective positions on such disagreement. Each Party shall have fifteen (15) business days from receipt of the other Party’s submission to submit to the Expert and the other Party a written response thereto, which shall include any scientific, technical or commercialization information in support thereof (the “Second Submission Date”). The Expert shall have the right to meet with the Parties, either alone or together, as necessary to make a determination.

16.3.3 No later than ten (10) business days after the Second Submission Date, the Expert shall make a determination by selecting the resolution proposed by one (1) of the Parties that the Expert deems as a whole to be the most fair and reasonable to the Parties in light of the totality of the circumstances. The Expert shall provide the Parties with a written statement setting

forth the basis of his/her determination in connection therewith. The decision of the Expert shall be final and conclusive.

16.3.4 This Section 16.3 shall not prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event of a breach or prospective breach of this Agreement by the other Party which would cause irreparable harm to the first Party.

Acura Pharmaceuticals Partners with Egalet Corporation to Commercialize Immediate Release Oxycodone Product Utilizing Acura’s Aversion® (Abuse-Deterrent) Technology

Palatine, IL (January , 2015) - Acura Pharmaceuticals, Inc. (NASDAQ: ACUR), today announced that the Company has entered into a Collaboration and License Agreement (the “Agreement”) with Egalet US, Inc. and Egalet Ltd. (together “Egalet”, subsidiaries of Egalet Corporation (NASDAQ: EGLT), which is also a party to the Agreement with obligations thereunder) granting Egalet exclusive worldwide rights to commercialize Acura’s immediate release oxycodone hydrochloride tablets product which incorporates Acura’s patented Aversion® (abuse-deterrent) Technology platform. The licensed product, formerly known as Oxecta, will be marketed by Egalet under the name OXAYDO™. OXAYDO is FDA approved in 5mg and 7.5mg strengths for the treatment of acute and chronic moderate to severe pain.

Acura and Egalet will form a joint steering committee to coordinate commercialization strategies and the development of product line extensions. Egalet will be responsible for all commercial, regulatory and manufacturing activities. The parties are working to transition the product to Egalet for commercial launch in the U.S. as soon as commercially practical.

The Agreement provides for an upfront cash payment of $5.0 million to Acura upon execution, with an additional $2.5 million due upon the later of (i) June 30, 2015 and (ii) the first commercial sale of the Product in the U.S.; but in no event later than January 1, 2016. Acura is to receive an additional one-time payment of $12.5 million when annual world-wide net sales of OXAYDO first reach $150 million in a calendar year. Acura is also to receive a stepped royalty at percentage rates from mid-single digits to double digits based on the level of OXAYDO world-wide net sales in a calendar year (including any product line extensions). Royalties will be payable on the first commercial sale of OXAYDO and expire, on a country-by-country basis, upon the expiration of Acura’s patent in such country.

▇▇▇ ▇▇▇▇▇, President and CEO said, “We are excited to partner with Egalet who, like us, is committed to address the problem of prescription opioid abuse. We believe Egalet shares our objective of aggressively bringing OXAYDO to the market and introducing the product to the healthcare community. Egalet is developing complementary extended-release abuse-deterrent technologies that could create, long term, an exciting portfolio of products to treat pain”.

The Company will host a conference to discuss the Agreement with Egalet on [*****] January , 2015 at 8:30 a.m. ET. To participate in the live conference call, please dial xxx-xxx-xxxx (U.S. and Canada) five to ten minutes prior to the start of the call. The participant passcode is yyyyy.

About Acura Pharmaceuticals

Acura Pharmaceuticals is a specialty pharmaceutical company engaged in the research, development and commercialization of product candidates intended to address medication abuse and misuse, utilizing its proprietary LIMITX™, AVERSION® and IMPEDE® Technologies. LIMITX contains ingredients that are intended to reduce or limit the rate or extent of opioid release when multiple tablets are ingested. AVERSION contains polymers that cause the drug to gel when dissolved; it also contains compounds that irritate the nasal passages if the product is snorted. IMPEDE is designed to disrupt the processing of pseudoephedrine from tablets into methamphetamine.

In June 2011, the U.S. Food and Drug Administration approved our oxycodone HCl immediate-release tablets which incorporate the AVERSION Technology. The Company has a development pipeline of additional AVERSION Technology products containing other opioids.

In December 2012, the Company commenced commercialization of NEXAFED® (pseudoephedrine HCl), a 30 mg immediate-release abuse-deterrent decongestant. This next generation pseudoephedrine tablet combines effective nasal congestion relief with IMPEDE Technology, a unique polymer matrix that disrupts the conversion of pseudoephedrine into the dangerous drug, methamphetamine.

Forward-Looking Statements

This release contains forwarding-looking statements which reflect management’s current view of future events and operations, including, but not limitation to; statements pertaining to the potential of OXAYDO™ to reduce prescription opioid abuse; statements pertaining to the expected timetable for launch of OXAYDO™; and statements pertaining to the potential success of the Company’s collaboration with Egalet, including the payments to be received under the Agreement. These forward-looking statements involve certain significant risks and uncertainties and constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Some important factors that may cause actual results to differ materially from the forward-looking statements include dependence on the successful launch and commercialization of OXAYDO™; dependence on Egalet’s ability to successfully manufacture or have manufactured OXAYDO™ for commercial sale; dependence on Acura’s and Egalet’s compliance with FDA and other government regulations that relate to their respective businesses; dependence on the successful development and commercialization of product line extensions to OXAYDO™; and dependence on unexpected changes in technologies and technological advances. Other important factors that may cause actual results to differ materially from the forward-looking statements are discussed in the “Risk Factors” section and other sections of Acura’s Form 10-K for the year end December 31, 2013 and Acura’s Form 10-Q for the quarter ended September 30, 2014, each of which are on file with the U.S. Securities and Exchange Commission. Acura does not undertake to publicly update or revise any of its forward-looking statements even if experience or future changes show that the indicated results or events will not be realized.

EGALET PRESS RELEASE

Egalet Announces Agreement to License Marketed Pain Treatment

Wayne, PA (January , 2015) - Egalet Corporation (Nasdaq: EGLT) (“Egalet”) today announced that it has agreed to license from Acura Pharmaceuticals, Inc. (Nasdaq: ACUR) worldwide rights to OXAYDO™ (oxycodone HCI, USP) tablets for oral use only -CII, the first and only approved immediate-release oxycodone product formulated to deter abuse via snorting. OXAYDO is indicated in the United States for the management of acute and chronic moderate to severe pain where the use of an opioid analgesic is appropriate.

“With OXAYDO, physicians now have an immediate-release opioid product designed to discourage abuse via snorting,” said ▇▇▇▇▇▇▇ ▇▇▇▇▇, MD, chief medical officer of Egalet. “This is an important addition to extended-release opioids with abuse-deterrent properties to help address the broader public health challenge of opioid misuse and abuse. In addition, marketing of OXAYDO will help us build relationships with future prescribers of our Guardian™ Technology products.”

Under the terms of the agreement with Acura Pharmaceuticals, Egalet has licensed worldwide rights to OXAYDO for an upfront payment of $5 million, a milestone payment of $2.5 million upon first commercial sale, a payment of $12.5 million when the product has achieved $150 million in net sales in a calendar year and a tiered royalty of single-digit to double-digit percent based on sales thresholds.

OXAYDO™ (previously known as OXECTA™) is the first immediate-release opioid analgesic formulated with Aversion Technology® intended to discourage abuse associated with snorting. This single-agent product has no acetaminophen and therefore does not carry the liver toxicity associated with APAP products. The most common adverse reactions with OXAYDO are nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia and somnolence.

Egalet plans to launch OXAYDO in the third quarter of 2015. Egalet will provide updates on commercial activities in the first quarter of 2015.

About Acute Pain

Acute pain is pain that comes on quickly, can be severe, but lasts a relatively short time.(i) Acute pain has many different causes including surgery, broken bones and dental work, among others. Acute pain can be mild and last for just seconds or it might be severe and come and go over weeks or months. In most cases, acute pain does not last longer than six months, and it resolves

when the underlying cause of pain has been treated or has healed. Unrelieved acute pain, however, might lead to chronic pain.(ii)

There are approximately 100 million Americans—more than those affected by heart disease, cancer, and diabetes combined—who suffer from chronic pain that is often undertreated according to the Institute of Medicine. It is also the most common reason patients seek medical care, resulting in $635 billion annually in both medical costs and decreased work productivity. Chronic pain is typically defined as pain that lasts beyond the healing of an injury or that persists beyond three months. Common types of chronic pain include low back pain, arthritis, headache and face and jaw pain. Severe pain typically stops an individual from participating in activities and causes patients to change their behavior to avoid such activities. According to an article in the New England Journal of Medicine, chronic pain is associated with functional loss and disability, reduced quality of life, high health care costs, and premature death. Chronic pain also can result in isolation, depression, sleep disorders and other issues that have a negative impact not only on patients but family members as well.

It is important that these patients whose chronic pain often interrupts their daily lives gain and maintain access to adequate pain relief. Opioids analgesics play an important role in the management of moderate to severe pain and are the most widely prescribed products for pain, with prescriptions exceeding 200 million in 2013.

Important Safety Information for OXAYDOTM (oxycodone HCl, USP) Tablets for oral use only - CII

OXAYDO is an immediate-release oral formulation of oxycodone HCl indicated for the management of acute and chronic moderate to severe pain where the use of an opioid analgesic is appropriate.

OXAYDO is contraindicated in patients with respiratory depression, paralytic ileus, acute or severe bronchial asthma or hypercarbia, or known hypersensitivity to oxycodone or any components of the product.

Respiratory depression is the primary risk of OXAYDO and it must be used with extreme caution in patients with chronic obstructive pulmonary disease or cor pulmonale, in patients with decreased respiratory reserve, hypoxia, hypercapnia or pre-existing respiratory depression.

OXAYDO contains oxycodone HCl, an opioid agonist and a Schedule II controlled substance. Such drugs are sought by drug abusers and people with addiction disorders. OXAYDO can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing in situations where there is concern about an increased risk of misuse or abuse. OXAYDO may be abused by crushing, chewing, snorting or injecting the

product and these practices pose a significant risk to the abuser that could result in overdose and death.

Patients receiving central nervous system depressants concomitantly with OXAYDO may exhibit an additive central nervous system depression. When such combined therapy is contemplated, the dose of one or both agents should be reduced. Patients should not consume alcoholic beverages, or any medications containing alcohol while taking OXAYDO.

OXAYDO may cause severe hypotension in patients whose ability to maintain blood pressure has been compromised. OXAYDO may produce orthostatic hypotension in ambulatory patients. OXAYDO must be administered with caution in patients in circulatory shock.

Serious adverse reactions that may be associated with OXAYDO include: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension and/or shock. The most common adverse reactions are nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia and somnolence.

In opioid naïve patients, start dosing OXAYDO with five to 15 mg every four to six hours as needed for pain. OXAYDO should not be given to anyone other than the individual for whom it was prescribed. Keep OXAYDO in a locked cabinet, drawer or medicine safe so that it will not be stolen.
