Section 3.3 Net Sales Reporting and Payment.

(a) Within [* * *] ([* * *]) days after the end of each Calendar Quarter in which a sale of GSK Supplied Product has been made by PAR (or its Affiliates) in the Territory, PAR shall submit to GSK and Spectrum a written report (the “Net Sales Split Report”) containing the following information regarding such preceding Calendar Quarter: an itemized accounting and calculation of the total Net Sales of GSK Supplied Product sold by PAR (or its Affiliates) during such preceding Calendar Quarter in the Territory and the amount of any Net Sales Split due GSK on such Net Sales, and such report shall include information in sufficient detail reasonably necessary for GSK to confirm the accuracy of the amount of the Net Sales Split due GSK, if any, during such preceding Calendar Quarter.

guidance which clarifies the Parties’ obligations under the U.S. Deficit Reduction Act of 2005, which may be applicable to this Agreement, then the Parties shall meet to consider whether modifications to this Agreement or the procedures are appropriate.

(c) PAR agrees, represents and covenants it (and its Affiliates) shall transport, store distribute, sell and promote GSK Supplied Product in the Territory in compliance with all Applicable Laws regarding the promotion and marketing of GSK Supplied Product, including, but not limited to, with respect to the U.S. Federal Food, Drug and Cosmetics Act of 1938, as amended, and the Prescription Drug Marketing Act of 1987.

(a) Exclusive Supply.

(i) PAR hereby agrees and acknowledges that, subject to the terms and conditions of this Agreement, PAR and its Affiliates shall receive one hundred percent (100%) of its (and its Affiliates’) requirements of Generic Injection Product and Generic [* * *] Product in the Territory from GSK (or GSK’s Affiliates) during the Supply Term. PAR hereby agrees and acknowledges that, during the Supply Term, PAR (and its Affiliates) shall not, directly or indirectly, purchase, receive, make, have made, use, sell, offer for sale or import any Product, as applicable, in the Territory with the sole exception of its rights to market and sell GSK Supplied Product in the Territory as explicitly set forth in this Agreement and as permitted in the Settlement Agreement.

(ii) GSK agrees and acknowledges that from the Execution Date until the Supply Termination Date (subject to Section 4.1(d), if applicable) GSK (and its Affiliates) shall not, directly or indirectly, through a Third Party sell or supply for import/export any Generic Injection Product or any Generic [* * *] Product ([* * *]). Notwithstanding the foregoing, PAR agrees and acknowledges that nothing in this Agreement shall prohibit GSK and its Affiliates from making, having made, using, selling to any Person, having sold to any Person, and importing Products approved by the FDA as of the Execution Date or other components of Generic Injection Products or the Generic [* * *] Products (including the Product) in the Territory in each case under an applicable GSK brand name, label or trademark (including the Imitrex^{^®} trademark) with the exception of a Generic Equivalent of the Imitrex^® [* * *]. Subject to the first sentence of this Section 4.2(a)(ii), nothing in this Agreement shall prohibit GSK and its Affiliates from making, or having made, or using, or selling or having sold or importing (individually, or as a blend), the components of the Generic Injection Product or the Generic [* * *] Product for sale (individually, or as a blend) by GSK or its Affiliates or any Third Party in the Territory during and after the Supply Term. GSK hereby represents [* * *].

[* * *] shall be as determined on a [***] shall use [***] in the event of such a [***].

(b) Specifications and Supply. GSK hereby represents, warrants and covenants that all GSK Supplied Product shall, with the exception of information provided to GSK by PAR: (i) not be misbranded or adulterated under Applicable Law, (ii) be in fully finished form, labeled and packaged for supply to the ultimate consumer in accordance with Applicable Law, (iii) meet the applicable specifications and requirements set forth in Schedule 4.2(b)(iii), (iv) be manufactured, labeled, packaged and stored in accordance with specifications in the applicable NDA, cGMP, and Applicable Law and (v) be capable of maintaining conformity to said specifications and requirements when handled and stored in accordance with the Labeling until the applicable expiry date of such GSK Supplied Product. GSK (or its Affiliate) may have manufactured, and supplied to PAR, GSK Supplied Product from any of GSK’s (or its Affiliates or its or their supplier’s or subcontractor’s) FDA approved and registered manufacturing facilities. All GSK Supplied Product shall be supplied to PAR and its Affiliates in compliance with Applicable Law, including cGMP and the Quality Agreement (“Quality Agreement”), which shall be entered into by the Parties within thirty (30) days after the Execution Date (but in any event prior to the release of the Initial Quantity to PAR) and shall be substantially in the form set forth in Schedule 4.2(b). GSK shall use commercially reasonable efforts to promptly respond to any reasonable inquiries from PAR regarding the supply of GSK Supplied Product.

(i) Except as is set forth below with regard to the Initial Quantity during the Supply Term, at least [* * *] ([* * *]) days prior to the start of each calendar month, PAR shall provide GSK (or its Affiliate) with a written firm order for such upcoming calendar month. By the first of each calendar month, PAR shall also provide GSK (or its Affiliate) with a written estimate of the quantities of GSK Supplied Product in the Territory PAR and its Affiliates require for the next succeeding [* * *] ([* * *]) months on a monthly basis (in the forecast format set forth on Schedule 4.2(c)) (the “Forecast”). Each of such Forecast shall contain the applicable [* * *] ([* * *]) calendar months firm orders and the remaining [* * *] ([* * *]) non-binding monthly estimates for that applicable period. When PAR shall place a firm order with GSK (or its Affiliate) for its GSK Supplied Product requirements at least [* * *] ([* * *]) days in advance of the start of each calendar month, GSK (or its Affiliate) shall respond to PAR within [* * *] ([* * *]) Business Days after receipt of such firm order, and in the event GSK (or its Affiliate) responds other than by accepting the firm order, the Parties shall cooperate and use good faith efforts to meet as closely as reasonably possible the Reasonable Quantity Requirements and schedule for delivery specified in the firm order, subject to the provisions of subsections (ii) below. Once a firm order is agreed upon by the Parties, PAR shall amend the firm order to reflect the quantity and delivery schedule agreed by the Parties and send to GSK (or its Affiliates) such revised firm order and a purchase order covering such quantities and delivery date, and GSK (or its Affiliate) shall have the obligation to supply such quantity to PAR pursuant to the terms hereof. PAR shall promptly reimburse GSK for any

and all documented, reasonable costs and expenses incurred by GSK (or its Affiliate) that arise from any canceled or materially modified firm order (without GSK’s prior written consent) after acceptance thereof by GSK (or its Affiliate), including all obsolete material that can not be reasonably utilized by GSK or its Affiliate. The previous sentence shall not limit GSK’s remedies or damages in the event PAR cancels or materially modifies any firm order, and PAR shall not modify or cancel the last firm order in the Supply Term. In the event the Parties reasonably agree that a Third Party Generic Sumatriptan Product is likely to in the immediate future, or has, become available for commercial sale in the Territory, the Parties shall in good faith review and adjust the then-existing Forecast in light of the presence of such Third Party Generic Sumatriptan Product in the Territory, provided the Parties shall use their commercially reasonable efforts to mitigate all losses and expenses related to such revisions to the Forecast.

The last firm order and Forecast shall be received and agreed by GSK not less than [* * *] ([* * *]) days prior to the Supply Termination Date. The firm orders for the last [* * *] ([* * *]) months of the Supply Term shall each not exceed [* * *] percent ([* * *]%) of the average monthly demand for GSK Supplied Product over the prior twelve (12) month period (determined on a sku-by-sku basis), unless PAR can provide reasonable evidence to GSK that there is adequate demand over the remainder of the Supply Term for GSK Supplied Product in excess of such limits. Upon termination or expiration of this Agreement, all firm orders and Forecasts are to be automatically terminated, except to the extent that backordered firm orders remain unfilled. PAR acknowledges and agrees that GSK relies on the [* * *] ([* * *]) month firm zone orders provided by PAR for the purpose of manufacturing planning and ordering necessary materials and components for the production of GSK Supplied Product. In the event PAR does not issue purchase orders in a timely manner (as described in this Section 4.2(c)) covering any [* * *] ([* * *]) month firm zone, PAR agrees that in the event GSK decides in its sole discretion to waive the firm zone requirements set forth herein: (A) GSK is entitled to reasonably rely upon the applicable [* * *] month firm zone last provided by PAR in the Forecast for the purpose of manufacturing planning and ordering necessary materials and components for the production of GSK Supplied Product and (B) in the event GSK is unable to reasonably utilize any such materials and components in the event PAR’s purchase orders are less than as set forth in the firm orders for such [* * *] ([* * *]) month firm zone, PAR shall reimburse GSK for all reasonable out-of-pocket costs incurred by GSK for any such obsolete materials and components, provided GSK uses its reasonable efforts to mitigate the costs associated with such obsolete materials and components. For the avoidance of doubt, GSK shall, in its sole discretion, decide whether or not it (or its Affiliates) will supply PAR with GSK Supplied Product absent purchase orders issued in a timely manner (as described in this Section 4.2(c)) for any [* * *] ([* * *]) month firm zone, however GSK shall reasonably consider supplying PAR in such instance, consistent with GSK’s reasonable ability to do so.

(ii) Each purchase order shall specify a delivery date which shall be at least [* * *] ([* * *]) days after the date of the purchase order. Should a purchase order call for shipment of quantities of GSK Supplied Product in excess of [* * *] percent ([* * *]%) of the immediately preceding estimated requirements previously provided to GSK (or its Affiliate) in the Forecast, GSK (or its Affiliate) will use its Commercially Reasonable Efforts, but shall not be obligated, to supply that portion of excess by the dates instructed by PAR; provided, however, in no event shall GSK (or its Affiliates) have any obligation to forego manufacture of any GSK (or its Affiliates’) products on common equipment that would have a material adverse consequence to GSK business in order to deliver GSK Supplied Product to PAR or its Affiliates in excess of the preceding Forecast. Notwithstanding anything to the contrary, PAR’s first firm orders for the [* * *] ([* * *]) month firm zone for GSK Supplied Product from GSK shall be in the quantities specified in Schedule 4.2(d). GSK (and its Affiliates) shall not be obligated to supply to PAR (or its Affiliates) quantities of GSK Supplied Product in excess of GSK’s (or

its Affiliate’s) branded Imitrex^® [* * *] product ([* * *]presentations) manufacturing capacity (with such capacity being defined herein as GSK’s [* * *] product ([* * *] presentations) capacity without regard to individual presentation capacity – all subject to PAR’s compliance with the forecasting and firm order requirements in this Agreement). In no event shall such capacity be less than such capacity existing as of the Execution Date.

(iii) Delivery of GSK Supplied Product ordered hereunder from GSK (or its Affiliate) to PAR and its Affiliates shall be [***] (Incoterms 2000), whereby [***] and [***] shall bear all risk of loss or damage, and costs of insurance and shipping associated with the GSK Supplied Product [***].

(iv) Attached hereto as Schedule 4.2(d), is PAR’s current good faith non-binding estimate of its (and its Affiliates’) requirements of GSK Supplied Product for the Territory for the [* * *] ([* * *]) months (including the Initial Quantity) following the Launch Date and the remainder of the Forecast. Following the Execution Date, PAR shall provide GSK an updated version of the Forecast on a [* * *] basis. [* * *] ([* * *]) days after the later of (A) [***] and (B) the date GSK notifies PAR of its ability (or inability) to supply PAR with the Generic [* * *] Product in the [* * *], PAR shall provide GSK with a definitive Forecast (in the form applicable to such Launch Date) and binding purchase orders for the [* * *] ([* * *]) months following the Launch Date (such total to include the Initial Quantity) and such Forecast and binding purchase orders shall not vary by more than [* * *] percent ([* * *]%) from the last non-binding Forecast provided to GSK (as determined on a monthly basis) subject to the last sentence of the first paragraph of Section 4.2(c)(i).

(v) In ordering and delivering GSK Supplied Product, as the case may be, GSK (or its Affiliates) and PAR may use their respective standard forms and documents in ordering and delivering the GSK Supplied Product, provided that nothing in those forms or documents shall be construed to modify or amend the terms and conditions of this Agreement, and, in the case of any conflict herewith, the terms and conditions of this Agreement shall control.

(d) Initial Quantity.

(i) PAR’s good faith estimate of the initial quantity of GSK Supplied Product that GSK (or its Affiliate) shall supply PAR and its Affiliates is set forth on Schedule 4.2(d) hereto (the “Initial Quantity”). So as to allow GSK an appropriate opportunity to manufacture such Initial Quantity, the Initial Quantity [* * *]. GSK (or its Affiliate) shall deliver the Initial Quantity to PAR (pursuant to Section 4.2(c)(iv)) at least [* * *] days prior to the anticipated Launch Date.

(ii) Title to the Initial Quantity will remain with GSK until the Launch Date, and upon the Launch Date title to the Initial Quantity shall automatically transfer to PAR; [***]. [***] will store the Initial Quantity in one of its facilities until the Launch Date and shall not, directly or indirectly, make available, consign, transfer, sell or make available for sale (or any other conveyance whatsoever) the Initial Quantity until the Launch Date occurs. On the Launch Date, [***].

(iii) The Parties shall use their Commercially Reasonable Efforts to make all reasonable manufacturing preparations to enable GSK to be able to meet the obligations set forth in Section 4.2(d)(i) above, and as of the Execution Date, the Parties shall exercise their reasonable efforts, and shall co-operate with each other, to obtain all necessary certifications, permits and other registrations required pursuant to Applicable Law to enable GSK (or its Affiliate) to manufacture and supply, and PAR and its Affiliates to import/export, sell and distribute, the GSK Supplied Product pursuant to the provisions of this Agreement.

(e) Labeling. All GSK Supplied Products shall bear a generic label specifying PAR as the distributor and displaying the logo PAR artwork supplied by PAR to GSK, and as agreed by GSK pursuant to the remainder of this Section 4.2(e). The label shall also include any references to Spectrum as conveyed by PAR and Spectrum to GSK in accordance with the Applicable Law, [***]. All GSK Supplied Product Labels, packaging or trade dress [***] shall comply with Applicable Law (including the terms of the applicable NDA), and, subject to the first sentence of this Section 4.2(f), [***]. Should PAR or GSK desire or be required pursuant to Applicable Law to make any change in any such Labels or Labeling, GSK shall be responsible for procuring the updating of all artwork and text associated with such change and providing such changes to PAR. Upon approval by GSK, GSK shall make all necessary arrangements for such changed Labels or Labeling to be printed and shall provide to PAR agreed artwork documents for PAR’s review. PAR shall, within one (1) week of receipt of agreed artwork documents, either provide GSK any necessary corrections thereto or notify GSK of its approval of such agreed artwork documents. [***] If a change of Labels or Labeling that was requested by PAR, required pursuant to Applicable Law, or due to an assignment of this Agreement by Spectrum pursuant to Section 9.1 results in obsolete inventory of former Labels or Labeling that GSK cannot otherwise use, [***]. PAR shall supply GSK with all of PAR’s necessary artwork, text, SKU numbers and other necessary items by the dates reasonably requested by GSK, so that GSK can prepare the Labels and packaging for the Initial Quantity. GSK’s obligations to supply PAR and its Affiliates with GSK Supplied Product, including the Initial Quantity by the specified delivery date, shall be contingent upon GSK’s timely receipt of the foregoing artwork, text, SKU and NDC numbers and other necessary items from PAR.

(f) Manufacturing. PAR and GSK hereby agree to follow and conduct their respective activities in accordance with the terms of Applicable Law, the Quality Agreement and this Agreement. GSK (or its Affiliate) expressly reserves the right to select, and subsequently change, the manufacturing sites for the GSK Supplied Product at its sole discretion, and will provide not less than one hundred eighty (180) days prior notice to PAR if the manufacturing of the GSK Supplied Product is to be moved to a site other than those identified in the applicable NDA provided, however, that GSK shall only use manufacturing sites registered with FDA and in compliance with Applicable Law, and shall ensure that its selection or change of manufacturing sites will not: (i) adversely affect its ability to fulfill its then current supply obligations to PAR and its Affiliates pursuant to this Agreement; or (ii) cause PAR or its Affiliates to incur additional material expenses or costs. In the event that GSK (or its Affiliate) desires to make a change of manufacturing sites that will adversely affect the supply obligations described in the immediately preceding sentence, then GSK shall at its own risk of loss, use its Commercially Reasonable Efforts to stockpile such quantities of GSK Supplied Product as may be required to deliver up to the volume of GSK Supplied Product ordered by PAR and its Affiliates pursuant to this Agreement. Subject to this Section 4.2(f), GSK (or its Affiliate) may dual-source the GSK Supplied Product from any FDA-registered facilities without prior notice to PAR; provided GSK provides PAR with the ability to identify the manufacturing facility for each lot.

(g) Delivery. GSK (or its Affiliate) shall use its Commercially Reasonable Efforts to deliver, pursuant to Section 4.2(c)(iii), to PAR and its Affiliates all such GSK Supplied Product as may be ordered by PAR and its Affiliates under a purchase order issued to GSK (or its Affiliate) pursuant to this Agreement no earlier than [* * *] ([* * *]) days prior to the delivery date specified in PAR’s purchase order, and shall deliver such GSK Supplied Product no later than [* * *] ([* * *]) days after the date specified in PAR’s purchase order unless otherwise agreed. PAR shall pick-up the GSK Supplied Product on the applicable delivery date and pursuant to Section 4.2(c)(iii) and Section 4.2(d)(i) as applicable. Nothing herein shall be construed as limiting the Parties’ ability to mutually agree in writing to any adjustment to a delivery date without any modification to a then outstanding purchase order or Forecast. GSK (or its Affiliate) shall provide an invoice and a certificate of conformance (except that with respect to the Initial Quantity such certificate shall be supplied as set forth in Section 4.2(d)(i)) to PAR for each lot of GSK Supplied Product shipped to PAR and its Affiliates which certifies that such GSK Supplied Product meets cGMP and meets the applicable specifications set forth in Schedule 4.2(b)(iii).

(h) Rejection and No Returns to GSK. Within [* * *] ([* * *]) days of receipt of any GSK Supplied Product, PAR and its Affiliates may perform appropriate inspections to determine whether the GSK Supplied Product meets the applicable specifications set forth in Schedule 4.2(b)(iii) and in accordance with the Quality Agreement and the requirements of this Agreement. Any GSK Supplied Product not refused by PAR within [* * *] ([* * *]) days of receipt of shipment shall be deemed accepted by PAR. If PAR wishes to refuse acceptance, PAR shall within such [* * *] ([* * *]) days time, inform GSK in writing of its refusal to accept the batch(s), and the reasons therefor. If the Parties do not agree on the refusal or rejection of GSK Supplied Product, then either Party may refer the matter for final review to an independent Third Party of national reputation reasonably acceptable to both Parties for the purpose of determining the results. Any determination by such Third Party shall be binding upon both Parties. The cost of any such review and evaluation by an independent Third Party shall be borne by PAR if it is determined that the GSK Supplied Product conforms to the requirements of this Agreement, and by GSK if determined that it does not. GSK shall, as promptly as is reasonably possible, either (i) make replacement delivery of conforming GSK Supplied Product, with GSK bearing the reasonable expenses associated therewith, or (ii) issue the appropriate credits to PAR, as requested by PAR. PAR shall, in

GSK’s reasonable discretion, either return to GSK or destroy any non-conforming GSK Supplied Product and provide to GSK written certification of destruction, with GSK bearing the reasonable expenses associated therewith, including reasonable destruction, transportation and reasonable handling costs, as applicable. Except as set forth in this Section 4.2(h) with respect to initial inspection of GSK Supplied Product, all sales of product from GSK to PAR shall be deemed final and non-returnable to GSK (except as provided for in Section 5.8(b)), and PAR shall be responsible for and shall process any and all aspects of its customer returns of GSK Supplied Product to PAR (except as provided for in Section 5.8(b).

(i) PAR shall have the right, not more than once annually and upon providing GSK with thirty (30) Business Days advance written notice, to inspect GSK’s factory (or factories, as applicable) that produce GSK Supplied Product for PAR, on a confidential basis and during normal business hours, for the sole purposes of ensuring such factory(ies) compliance with applicable cGMP and Applicable Law solely related to the manufacturing and storage of GSK Supplied Product. PAR’s inspection rights under this Section shall be limited to two (2) people for three (3) days, and shall not extend to any portions of such factory(ies), documents, records or other information which do not directly relate to the GSK Supplied Product. Inspection by PAR or documentation provided to PAR related to any of GSK’s suppliers or subcontractors related to the manufacturing and storage of GSK Supplied Product is subject to consent of such GSK supplier or subcontractor.

PAR shall immediately take appropriate actions to remedy such breach, including halting such sales, implementing procedures to ensure such breach does not re-occur, and recalling all such exported GSK Supplied Product, within thirty (30) days after receipt of notice thereof by GSK. Nothing in this paragraph shall in any way limit GSK’s remedies that may be available to it pursuant to this Agreement, including the right to terminate this Agreement for such breach pursuant to Section 7.2(a).

(c) PAR shall use its Commercially Reasonable Efforts to market and sell GSK Supplied Product to its distributors and other customers in the Territory, pursuant to the terms of this Agreement, for the duration of the Supply Term. PAR shall be solely responsible, at its expense, for all activities related to the sale, marketing, warehousing, shipping and distribution of the GSK Supplied Products in the Territory, including but not limited to advertising, pricing, customer contracting, maintenance of toll-free consumer telephone lines, processing of consumer mailers, maintenance of required websites and databases.

PAR shall be solely responsible for designing, preparing and distributing, at its sole expense and control, all advertising, marketing and promotional materials (including all written, printed, electronic, audio or video matter) used in its (or PAR’s Affiliates’) promotion, detailing, advertising and marketing of the GSK Supplied Product within the Territory (collectively “Promotional Materials”). For the avoidance of doubt, Promotional Materials shall not constitute Labels or Labeling hereunder. PAR will ensure that all of its Promotional Materials comply with, and all of its other advertising, marketing and promotional activities comply with, and PAR will be solely responsible and liable for any failure of such materials and activities to comply with, the applicable labeling and the applicable NDA and with Applicable Law, notwithstanding that such materials may have been previously reviewed or used by GSK (or its Affiliate). PAR shall be solely responsible for fulfilling regulatory requirements pertaining to its promotional activities, including without limitation sole responsibility for submitting all Promotional Materials prepared by or for it to the FDA at the time of initial dissemination by way of a Form FDA-2253, consistent with 21 CFR Section 314.81. To this effect, GSK will promptly place a letter on file with DDMAC with respect to the GSK Supplied Product, advising DDMAC that PAR (or its Affiliate) will be marketing and promoting the GSK Supplied Product and filing with DDMAC Form FDA-2253 for all promotional labeling and materials. Each Party agrees promptly to provide the other Party with a copy of any correspondence from a government agency relating to the GSK Supplied Product, including but not limited to the FDA, reflecting regulatory action being considered or taken by such government agency,

including without limitation copies of FDA Untitled Letters and Warning Letters. For avoidance of doubt, to the extent any of these correspondence or other materials provided to the other Party contain pricing information, such materials shall be redacted prior to providing the other Party with a copy thereof. PAR will absorb and be solely responsible for any damages, losses, expenses and costs incurred by PAR or GSK, its/their Affiliates, and its/their representatives and agents, arising from the failure of any Promotional Materials developed by PAR (or its Affiliate) and any promotional, advertising or marketing activities by PAR (or its Affiliate) to comply with the applicable labeling, the applicable NDA and with Applicable Law. Notwithstanding the foregoing, GSK will absorb and be solely responsible for any damages, losses, expenses and costs incurred by PAR or GSK, its/their Affiliates, and its/their representatives and agents, arising from the failure of any Labels or Labeling that were developed by GSK (or its Affiliate) for its branded Imitrex^® product and used in GSK Supplied Product to comply with the applicable NDA and with Applicable Law. If PAR (or GSK) receives an Untitled Letter or a Warning Letter on Promotional Materials relating to the Supplied Product: (i) PAR will fully cooperate with GSK, pursuant to Applicable Law, in responding to the FDA (or other applicable governmental agency), and (ii) PAR shall immediately cease its use of such Promotional Material; and (iii) PAR shall, for a period of twelve (12) months thereafter, prior to the use or dissemination of any Promotional Materials submit such Promotional Materials for prior review and approval by DDMAC and shall not use any such Promotional Materials until approved by DDMAC. For the avoidance of doubt, except for such responsibilities and liabilities attributable to GSK under Applicable Law, GSK (and its Affiliates) shall have no responsibilities or liabilities whatsoever with respect to the Promotional Materials and promotional, advertising or marketing activities relating to PAR’s Generic Injection Product or Generic [* * *] Product.

During the Term of this Agreement, GSK (or its Affiliate) will be responsible for any required reporting of matters regarding the manufacture, integrity, and conformance to specifications of GSK Supplied Product for PAR to the FDA in accordance with Applicable Law; except for such reports that PAR is required to make under this Agreement or Applicable Law.

The Parties (or their respective Affiliates) shall collaborate in developing procedures for providing information on GSK Supplied Product complaints and inquiries and such

procedures will be outlined in the Quality Agreement. Nothing in this Section 5.8(a) shall affect the Parties’ (and their respective Affiliates’) obligations with respect to pharmacovigilance reporting, as detailed in Section 4.4.

ARTICLE VI - INTELLECTUAL PROPERTY AND CONFIDENTIAL INFORMATION

Section 6.1 Ownership of Pre-Existing Intellectual Property Rights. Any intellectual property rights (including patents, patent applications, know-how, trade secrets, copyrights, trade dress, housemarks and trademarks) owned by either Party and their respective Affiliates prior to the Execution Date shall remain solely owned by such Party (or their respective Affiliates, as applicable). Each of the Parties shall not during the Term, or at any time thereafter, represent or assert that it is the owner of any such intellectual property rights of the other Party (or their respective Affiliates), whether or not such rights are registered. For the avoidance of doubt, the Parties agree that each of the Parties shall have no rights to use any trademark, housemark, copyright, or trade dress, of the other, and PAR specifically has no right, directly or indirectly, to use the Imitrex^{^®} trademark for any purpose, except as Applicable Law may permit a Third Party to use the trademark of another Person without a license, such as fair use references to the mark. Except as otherwise explicitly provided herein, no right, express or implied, is granted by the Agreement to use in any manner the name “GSK,” “PAR,” “Glaxo Group Limited,” “Wellcome Manufacturing PTE Limited,” “Penn Labs”, “Penn Labs Inc.” or “GlaxoSmithKline” or the name of any Affiliate of any Party. Without limiting the foregoing and as an example of use permitted by Applicable Law without a license, this Agreement does not prohibit PAR from stating in its Promotional Materials, in compliance with Applicable Law, that the GSK Supplied Product is the generic equivalent of the applicable Imitrex^{^®} injection branded product or that the GSK Supplied Product is manufactured by Penn Labs (a GlaxoSmithKline company) under the applicable NDA (and if PAR or its Affiliates use such a statement, PAR agrees to include the following trademark ownership legend on such materials: “Imitrex^{^®} is a registered trademark of the GlaxoSmithKline group of companies”).

Section 6.2 Confidential Information, Publicity and Publication. PAR and GSK each hereby recognize and acknowledge that the other Party’s Confidential Information constitutes valuable and confidential information. Subject to other express provisions of this Agreement, the Parties each agree that as of the Execution Date and during the Term, and for a period of [* * *] after the effective date of termination for any reason of this Agreement or the date of the expiration hereof:

(a) Except as may be explicitly permitted in this Agreement, the Parties shall not disclose, directly or indirectly, in any manner whatsoever to any Third Parties any Confidential Information received from the other Party (or its Affiliates, as applicable) (the “Disclosing Party”) without first obtaining the written consent of the Disclosing Party, and the other Party (“Recipient”) shall keep confidential, all of the Disclosing Party’s Confidential Information that is disclosed to Recipient. Recipient agrees to use the same level of care in safeguarding the Disclosing Party’s Confidential Information that Recipient uses with its own confidential information of a similar nature, but in no event less than reasonable care. Recipient shall restrict disclosure of the Disclosing Party’s Confidential Information solely to those of its (or its Affiliate’s) employees or representatives having a need to know such Confidential Information in order to accomplish the purposes of this Agreement. Each Party represents that its respective employees and representatives who receive the Confidential Information of the Disclosing Party are advised by such party of the confidentiality obligations of this Agreement and shall maintain such Confidential Information in accordance with the confidentiality obligations set forth in this Article VI.

(b) Recipient shall not use the Disclosing Party’s Confidential Information in any manner whatsoever other than solely in connection with the exercise of its rights and the performance of its obligations under this Agreement.

(c) In the event Recipient is requested pursuant to, or required by, Applicable Law to disclose any of the Disclosing Party’s Confidential Information, it will notify the Disclosing Party promptly so that the Disclosing Party may seek a protective order or other appropriate remedy or, in the Disclosing Party’s sole discretion, waive compliance with the confidentiality provisions of this Agreement. At the Disclosing Party’s expense, Recipient will co-operate in all reasonable respects, in connection with any reasonable actions to be taken for the foregoing purpose. In any event, Recipient may furnish such Confidential Information as requested or required pursuant to Applicable Law (subject to any such protective order or other appropriate remedy) without liability hereunder, provided that the Recipient furnishes only that portion of the Confidential Information which Recipient is advised by its counsel is legally required, and Recipient exercises reasonable efforts to obtain reliable assurances that confidential treatment will be accorded the Disclosing Party’s Confidential Information.

(d) Upon the date of the expiration or termination of this Agreement for any reason, either Party may request in writing, and the other Party shall either: (i) promptly destroy all copies of the requesting Party’s Confidential Information in the possession of the other Party and confirm such destruction in writing to the requesting Party; or (ii) promptly deliver to the requesting Party, at the requesting Party’s expense, all copies of such Confidential Information in the possession of the other Party, provided, however, the other Party shall be permitted to retain one (1) copy of the requesting Party’s Confidential Information for the sole purpose of regulatory compliance. Additionally, both Parties shall immediately cease all use of the other Party’s Confidential Information including, without limitation, removing all references to such Confidential Information from its analyses, compilations, studies or other documents. All Confidential Information shall continue to be subject to the terms of this Agreement for the period set forth in this Section 6.2.

(e) Each Party represents and warrants to the other Party that it (or its respective Affiliates, as applicable) has, and shall have, all right, title, and ownership interest in and to its Confidential Information or it has, and shall have, the right to disclose its Confidential Information to the other Party. Each Party may seek to enforce all rights and legal remedies available under this Article VI or by law, including, without limitation, injunctive relief, specific performance and other equitable remedies in the event of a breach of the provisions of this Article VI by the other Party.

(f) Recipient shall cause its Affiliates to observe the terms of this Article VI hereof, and shall be responsible for any breach of its provisions by any of its Affiliates.

(g) Notwithstanding the provisions of this Article VI, the Parties agree that nothing contained in this Article VI shall prevent Recipient in any way whatsoever from disclosing any of the Disclosing Party’s Confidential Information, without obtaining Disclosing Party’s prior consent, to any Affiliate of Recipient or to any Third Party for the purposes of conducting their respective rights and obligations under this Agreement, provided such Third Party has undertaken an obligation of confidentiality similar to such obligations contained in Article VI herein with respect to the Disclosing Party’s Confidential Information.

Section 6.3 Publicity. The Parties shall keep this Agreement and its provisions confidential using at least the level of care they use for their own proprietary information. As of the Execution Date

and during the Term, no public announcement concerning the existence of, terms, or subject matter of this Agreement shall be made, either directly or indirectly, by any Party, without first obtaining the approval of the other Party and agreement upon the nature and text of such public announcement which such agreement and approval shall not be unreasonably withheld, except, in the opinion of legal counsel for the Party desiring to make such public announcement, as may be legally required by (i) the Applicable Law, including the United States Securities Act of 1933, as amended, the United States Securities Exchange Act of 1934, as amended, (ii) the listing standards or agreements of any national or international securities exchange or The NASDAQ Stock Market or other similar laws of a governmental authority or agency, (iii) to respond to an inquiry of a governmental authority or agency, or (iv) as may be required in a judicial, administrative or arbitration proceeding, in all instances seeking appropriate confidential treatment of this Agreement and the subject matter thereof and the Parties shall agree on any redacted forms of the Agreement that are filed publicly, such agreement not to be unreasonably withheld or delayed. The Party desiring to make any such public announcement (including those which are legally required) shall inform the other Party of the proposed announcement or disclosure in reasonably sufficient time prior to public release, which shall be not less than five (5) days (or such shorter period as the Parties may agree upon in writing, or such shorter period applicable to those public announcements which are legally required)) prior to release of such proposed public announcement, and shall provide the other Party with a written copy thereof in order to allow such other Party to comment upon such public announcement. Each Party agrees that it shall co-operate fully with the other with respect to all disclosures regarding this Agreement to any governmental or regulatory agencies, including requests for confidential treatment of proprietary information of either Party included in any such disclosure.

Any PAR contributions shall be acknowledged in any GSK publication.

Section 6.5 Filing Requirements. As of the Execution Date:

(a) PAR and GSK each hereby represent, warrant and covenant, after consultation with its legal counsel, that the act of executing this Agreement does not trigger or otherwise instigate any reporting, filing or other disclosure obligation on such Party’s (or any of its Affiliate’s) behalf pursuant to Applicable Law (excluding any U.S. Securities and Exchange Commission or Nasdaq Stock Market reporting or disclosure obligations or requirements and filings under the Medicare Prescription Drug Improvement and Modernization Act of 2003); provided, however, notwithstanding Section 6.2(c), if the execution of this Agreement were to trigger or otherwise instigate a reporting, filing or other disclosure obligation on such Party’s (or any of its Affiliate’s) behalf pursuant to Applicable Law, such Party shall immediately notify the other Party of such obligation, and such Party further agrees not to make, file, or issue such report, filing or disclosure, directly or indirectly (except in connection with any U.S. Securities and Exchange Commission or Nasdaq Stock Market reporting or disclosure obligations or requirements and filings under the Medicare Prescription Drug Improvement and Modernization Act of 2003), until the Parties, in good faith, agree upon the content, media and timing of such report, filing or disclosure.

(b) Notwithstanding anything to the contrary in this Article VI, as set forth in Title XI of the Medicare Prescription Drug Improvement and Modernization Act (Subtitle B – Federal Trade

Commission Review) signed into law on December 8, 2003, each of the Parties shall submit this Agreement, the Settlement Agreement and the Stipulation of Dismissal to the U.S. Federal Trade Commission (“Commission”) Bureau of Competition (“Bureau”) and the Assistant Attorney General within ten (10) business days of execution, and each Party shall present and (if necessary) discuss or respond to questions regarding this Agreement with the Bureau or the Assistant Attorney General, provided such Party requests the Bureau and the Assistant Attorney General treat this Agreement, as confidential to the extent legally permitted.

Section 6.6 Nothing in this Agreement shall be construed as preventing or in any way inhibiting either Party from complying with Applicable Law governing activities and obligations undertaken pursuant to this Agreement, in any manner which it reasonably deems appropriate, including, for example, by disclosing to regulatory authorities confidential or other information received from the other Party, subject to Section 6.2(c).

ARTICLE VII - TERM AND TERMINATION

Section 7.1 Term. This Agreement shall become effective as of the Effective Date and, unless sooner terminated pursuant to Section 7.2 below, shall automatically expire as of the Supply Termination Date, with the period between the Effective Date and such expiration or termination date being referred to as the “Term”.

Section 7.2 Termination.

(a) Termination for Breach. Each Party shall be entitled to terminate this Agreement by written notice to the other Party in the event that the other Party shall be in material default or material breach of any of its obligations hereunder in any material respect, and shall fail to remedy any such default or breach within sixty (60) days after written notice thereof by the non-defaulting/non-breaching Party. If such default or breach is not corrected within the foregoing sixty (60) day period, the non-breaching Party shall have the right to terminate this Agreement by giving written notice to the Party in default, provided the notice of termination is given within six (6) months of the default and prior to correction of the default.

(b) Termination upon Bankruptcy. Either Party may terminate this Agreement if, at any time, the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of its assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed with sixty (60) days after the filing thereof, or if the other Party shall propose or be a Party to any dissolution or liquidation, or if the other Party shall make an assignment for the benefit of creditors.

(c) Notwithstanding anything to the contrary in this Section 7.2, concurrent with providing written notice to PAR of a default or breach or GSK’s intent to terminate this Agreement, GSK shall provide the same written notice to Spectrum. Upon receipt of such notice, Spectrum or its designee shall, after the passage of thirty (30) days, have the right, but not the obligation, to assume all of PAR’s rights and obligations hereunder, including the correction of any default or breach by PAR of its obligations hereunder, within the applicable cure period.

(d) (i) If in the event after the first twelve (12) month period of the Supply Term the amount of the applicable Supply Price paid by PAR to GSK on the GSK Supplied Product reaches a level that is at or below GSK’s Cost of Goods, GSK shall notify PAR of such situation in writing and provide PAR with a revised Supply Price that covers GSK’s Cost of Goods (but is not in excess of [* * *] percent ([* * *]%) over GSK’s Cost of Goods. PAR shall then have the right, upon giving GSK two (2) months prior written notice (with such notice referencing this Section 7.2(d) as the reason for termination), to either terminate this Agreement or agree to remit to GSK such revised Supply Price.

(ii) Upon receipt of the written notice reference in subsection (i) above, PAR shall have the right, within thirty (30) days after receipt of such notice, to have an independent certified public accountant, satisfactory to GSK in GSK’s reasonable discretion, (the “COGS Auditor”) inspect GSK’s records relating to its Cost of Goods for the GSK Supplied Product for the four (4) months preceding such notice, for the sole purpose of determining the accuracy of GSK’s assertion that the Supply Price paid by PAR to GSK on such GSK Supplied Product has reached a level that is at or below GSK’s Cost of Goods for such GSK Supplied Product and that the increase in the new Supply Price reflects only the increase in GSK’s Cost of Goods (and is within the foregoing [* * *] percent ([* * *]%) limit). GSK shall permit the COGS Auditor to have confidential reasonable access during normal business hours to such records of GSK as may be reasonably necessary to verify such GSK statement. The COGS Auditor shall reach its conclusion as quickly as possible, but in no event more than a period of thirty (30) days, and notify the Parties of its conclusion in writing. In the event the COGS Auditor concludes that GSK’s statement was accurate, PAR shall either terminate this Agreement or agree to remit to GSK such revised Supply Price pursuant to Subsection (i) above. In the event the COGS Auditor determines GSK’s statement was inaccurate, GSK shall not be entitled to such increased Supply Price and the previous Supply Price shall remain applicable. The reasonable fees and expenses charged by the COGS Auditor shall be paid by PAR unless the COGS Auditor determines GSK’s statement was inaccurate, in which event such reasonable fees and expenses shall be paid by GSK. In no event shall GSK be obligated to reveal its Cost of Goods figures to PAR and such figures shall remain GSK Confidential Information, and the COGS Auditor shall report, in confidence, to PAR only its conclusions as to whether such GSK statement and revised Supply Price was accurate or inaccurate. GSK shall use its commercially reasonable efforts to keep the Cost of Goods below the Supply Price.

(e) This Agreement may be terminated at any time pursuant to the mutual written consent of GSK, PAR and Spectrum.

(f) This Agreement may be terminated and become null and void as of the Execution Date pursuant to the provisions of the Settlement Agreement.

(b) Notwithstanding anything to the contrary in this Section 7.3 or any other Section of this Agreement, termination or expiration of this Agreement in accordance with the provisions hereof and, the operation of any provisions of this Section 7.3, shall not in any way limit the Parties’ remedies that may be otherwise available to them in law or equity.

(i) Section 3.1, 3.2(b);

as well as those under any other provisions which by their nature are intended to survive any such termination or expiration, shall survive and continue to be enforceable.

damages), fees (but only reasonable attorneys fees and expenses and costs of litigation pertaining to such PAR Claim), and expenses paid or payable by PAR or a PAR Party to a Third Party (collectively, “PAR Losses”) to the extent that such PAR Losses result from or arise in connection with a claim, suit or other proceeding made or brought by a Third Party against PAR or a PAR Party (a “PAR Claim”) based on, resulting from, or arising in connection with:

(i) the breach of any obligation (including the failure by GSK to supply the GSK Supplied Product pursuant to the terms of this Agreement), covenant, agreement, representation or warranty of GSK or a GSK Party contained in this Agreement;

(ii) any violation of Applicable Law by GSK, or a GSK Party, in connection with the performance of GSK’s or its Affiliates’ obligations under this Agreement; or

(iii) [***]

provided, however, that GSK shall not be obligated to indemnify, defend or hold harmless PAR or a PAR Party under this Section from any PAR Claim or for any PAR Losses incurred by PAR or a PAR Party to the extent arising out of or attributable to (A) a breach by PAR, or any PAR Party of any obligation, covenant, agreement, representation or warranty of PAR, or any PAR Party contained in this Agreement, or (B) any act or omission by PAR or a PAR Party, which constitutes negligence, recklessness, gross negligence, or willful misconduct on the party of PAR or a PAR Party or (C) [***] to the extent PAR is responsible for indemnifying, defending and holding GSK and GSK Parties harmless for such [***] as set forth in Section 8.1(b).

(b) PAR Indemnification Obligations. PAR shall indemnify, defend and hold GSK and their respective Affiliates, and its and their employees, agents, officers, and directors (individually and/or collectively referred to hereinafter as a “GSK Party”) harmless from and against any and all losses, liabilities, damages (inclusive of indirect or incidental (but excluding special, consequential or punitive) losses or damages), fees (but only reasonable attorneys fees and expenses and costs of litigation pertaining to such GSK Claim), and expenses paid or payable by GSK or a GSK Party to a Third Party (collectively, “GSK Losses”) to the extent that such GSK Losses result from or arise in connection with a claim, suit or other proceeding made or brought by a Third Party against GSK or a GSK Party (a “GSK Claim”) based on, resulting from, or arising in connection with:

(i) the breach of any obligation, covenant, agreement, representation or warranty of PAR, or a PAR Party contained in this Agreement;

(ii) any act or omission by PAR, or a PAR Party which renders a GSK Supplied Product defective or unreasonably dangerous, creates or contributes to a [***], or constitutes recklessness, gross negligence, or willful misconduct on the part of PAR or a PAR Party, or results from any PAR or PAR Party’s failure to meet GSK’s applicable product handling, shipping, or storage specifications that have been provided by GSK to PAR in writing reasonably in advance of the effectiveness thereof;

(iii) any violation of Applicable Law by PAR or a PAR Party in connection with the performance of PAR’s or its Affiliates’ obligations under this Agreement (including any distribution, marketing, promotion, detailing, and sale of GSK Supplied Product by PAR in violation of Applicable Law);

(iv) [***]

provided, however, that PAR shall not be obligated to indemnify, defend or hold harmless GSK or a GSK Party from any GSK Claim or for any GSK Loss incurred by GSK or a GSK Party to the extent arising out of, or attributable to, (A) a breach by GSK or any GSK Party of any obligation, covenant, agreement, representation or warranty of GSK or a GSK Party contained in this Agreement; or (B) any act or omission by GSK, or a GSK Party, which constitutes negligence, recklessness, gross negligence, or willful misconduct on the part of GSK, or a GSK Party, or (C) [***] to the extent GSK is responsible for indemnifying, defending and holding PAR and PAR Parties harmless for such [***] as set forth in Section 8.1(a).

(i) Each indemnified Party shall notify the indemnifying Party in writing (and in reasonable detail) of the Claim within ten (10) business days after receipt by such indemnified Party of notice of the GSK Claim or PAR Claim, as the case may be, or otherwise becoming aware of the existence or threatened existence thereof (such GSK Claim or PAR Claim being referred to as a “Claim”). Failure to give such notice shall not constitute a defense, in whole or in part, to any claim by an indemnified Party hereunder except to the extent the rights of the indemnifying Party are materially prejudiced by such failure to give notice. The Indemnifying Party shall notify the indemnified Party of its intentions as to defense of the Claim or potential Claim in writing within ten (10) Business Days after receipt of notice of the Claim. If the indemnifying Party assumes the defense of a Claim against an indemnified Party, an indemnifying Party shall have no obligation or liability under this Article VIII as to any Claim for which settlement or compromise of such Claim or an offer of settlement or compromise of such Claim is made by an indemnified Party without the prior written consent of the indemnifying Party, which consent shall not be unreasonably withheld.

(ii) The indemnifying Party shall assume exclusive control of the defense and settlement (including all decisions relating to litigation, defense and appeal) of any such Claim (so long as it has confirmed its indemnification obligation responsibility to such indemnified Party under this Section 8.1(c) with respect to a given Claim); provided, however, that the indemnifying Party may not settle such Claim in any manner that would require payment by the indemnified Party, or would materially adversely affect the rights granted to the indemnified Party hereunder, or would materially conflict with the terms of this Agreement, or adversely affect the Products in or outside the Territory, without first obtaining the indemnified Party’s prior written consent, which consent shall not be unreasonably withheld.

(iii) The indemnified Party shall reasonably cooperate with the indemnifying Party in its defense of the Claim (including, without limitation, making documents and records available for review and copying and making persons within its control available for pertinent testimony in accordance with the confidentiality provisions of Article VI, and neither Party shall be required to divulge privileged material to the other) at the indemnifying Party’s expense. If the indemnifying Party assumes defense of the Claim, an indemnified Party may participate in, but not control, the defense of such Claim

using attorneys of its choice and at its sole cost and expense, with such cost and expense not being covered by the indemnifying Party. If an indemnifying Party does not agree to assume the defense of the Claim asserted against the indemnified Party (or does not give notice that it is assuming such defense), or if the indemnifying Party assumes the defense of the Claim in accordance with Section 8.1(c) yet fails to defend or take other reasonable, timely action, in response to such Claim asserted against the indemnified Party, the indemnified Party shall have the right to defend or take other reasonable action to defend its interests in such proceedings, and shall have the right to litigate, settle or otherwise dispose of any such Claim; provided, however, that no Party shall have the right to settle a Claim in a manner that would adversely affect the rights granted to the other Party hereunder, or would materially conflict with this Agreement, or would require a payment by the Party, or adversely affect the Products in or outside the Territory, without the prior written consent of the Party entitled to control the defense of such Claim.

(a) Negotiation. Except as set forth in Section 4.2(h) with respect to a disagreement regarding the rejection of GSK Supplied Product or as to a dispute arising out of the provisions of Section 4.2(a)(iii), if a dispute or controversy regarding any right or obligation under this Agreement arises between the Parties, the Parties will seek to resolve such dispute or controversy or failure to agree by good faith negotiation between senior management representatives of the Parties, to be commenced promptly after such dispute or controversy or failure to agree arises. If such dispute or controversy or failure to agree is not resolved by such negotiation within thirty (30) days after written notice by one Party to the other, each Party shall be free to pursue any other course of action available to such Party.

(b) With the exception of disputes arising out of the provisions of Section 4.2(a)(iii), the provisions of this Section 8.2 shall not restrict either Party’s rights to seek preliminary injunctive or other equitable relief from any court having jurisdiction, or to take action as such Party deems necessary to preserve its rights and to protect its interests.

(c) With respect solely to disputes arising out of the provisions of Section 4.2(a)(iii), such disputes will be settled through binding arbitration, if initiated by one of the Parties. The place of the arbitration shall be New York, NY, U.S.A. (unless the Parties agree otherwise) and the arbitration shall be in the English language and conducted in accordance with the American Arbitration Association (“AAA Rules”) on a expedited basis. The arbitration will be heard and determined by one (1) arbitrator, who will be jointly selected by GSK and PAR. If, within thirty (30) days following the date upon which a claim is received by the respondent, the Parties cannot agree on a single arbitrator, the arbitration will be heard and determined by three (3) arbitrators, with one arbitrator being appointed by each Party and the third arbitrator being selected by the two Party-appointed arbitrators. If either Party fails to select an arbitrator, or if the Party-appointed arbitrators cannot agree on a third arbitrator within sixty (60) days of the respondent receiving the claim, such arbitrator will be appointed by the AAA according to the AAA Rules. The arbitration award so given will be binding upon the Parties, accompanied by a reasoned opinion in writing (in English), and the judgment on the award may be entered in any court having jurisdiction thereof. Each Party will bear its own costs and expenses (including its attorney’s fees) associated with any arbitration initiated under this section, and each Party will bear an equal share of the arbitrators’ and administrative fees associated with any arbitration initiated under this section.

PHARMACOVIGILANCE AGREEMENT

Between

Glaxo Wellcome Manufacturing PTE Limited]

and

[PAR Pharmaceutical, Inc.]

for Generic Injection Product and Generic [* * *] Product

Effective date of this agreement: [INSERT DATE]

1.	Background

Glaxo Wellcome Manufacturing PTE Limited (collectively hereinafter “GSK”) and PAR Pharmaceutical, Inc. (hereinafter “PAR”) entered into a Supply and Distribution Agreement, regarding Generic Injection Product and the Generic [* * *] Product (hereinafter “Product”) dated as of [insert date] (hereinafter the “Main Agreement”). Hereinafter GSK and PAR may be referred to as the “Party” in the singular and “Parties” in the plural.

This Pharmacovigilance Agreement (the “Agreement”) has been prepared in accordance with Section 4.4 of the Main Agreement.

This Agreement describes the procedures, time frames and responsibilities that the Pharmacovigilance Departments of all Parties will employ to assure compliance with the applicable laws and regulations pertaining to safety reporting and its related activities.

Title 21 of the Code of Federal Regulations will be adhered to in relation to any applicable U.S. reporting requirements.

•

21 CFR § 314.80 (Post-marketing Reporting of Adverse Drug Experiences)

2.	Definitions

Adverse Event (AE)

Any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse.

Pregnancy

Pregnancy is not regarded as an AE per se. Reports of pregnancy involving an AE will be handled as AE reports. Reports of pregnancy that involve no AE will be handled as pregnancy reports and exchanged as specified in this agreement.

“Product(s)”

Product shall mean the Generic Injection Product and the Generic [* * *] Product for human use supplied to PAR (and its Affiliates) by GSK (and its Affiliates) pursuant to the provisions of this Agreement as further detailed in the specifications set forth in Schedule 4.2(b)(iii) to the Main Agreement for use in humans

"Territory"

Territory shall mean the United States of America (including the Commonwealth of Puerto Rico) its possessions and territories and U.S. military and/or government installations that are under the purview of the FDA.

3.	Responsibilities

PAR will notify GSK (with such notice made to the appropriate contact listed in Attachment 1) of all information (initial or follow-up) coming into its possession concerning AE or pregnancy reports associated with commercial or clinical uses, studies, investigations or tests with Product, in the Territory, whether or not determined to be attributable to Product. PAR will transmit such AE and pregnancy reports to GSK so that they are received by GSK within one (1) business day after receipt by PAR.

PAR will inform those who report AEs or pregnancies that the information provided to PAR will be forwarded to the manufacturer for appropriate follow-up.

GSK will be responsible for submitting AE and pregnancy reports regarding Product to the applicable authorities or agencies.

PAR will train their staff who will be managing reports regarding Product to ensure they have basic knowledge of AE and pregnancy reports and AE-related procedures.

4.	Means of Notification

The preferable method of notification to GSK is via encrypted e-mail (with pdf attachments if necessary) using receipt acknowledgement. Alternatively, notification to GSK may be via fax transmission.

Date of first receipt by PAR of any AE or pregnancy report must be recorded on each report sent. This includes initial and all follow-up receipt dates.

5.	Termination of the Pharmacovigilance Agreement

If the Product subject to this Agreement is subsequently divested or discontinued, or the overall Main Agreement between GSK and PAR is terminated, this Agreement will be terminated promptly. Assignability of this Agreement is to the same extent as the Main Agreement.
