the portion of the API shipment which does not conform to the Active Pharmaceutical Ingredient Specifications and bear all reasonable, documented expenses of shipping and testing the shipment samples. Notwithstanding the foregoing, the independent
expert may also determine that additional sample testing by an independent laboratory is necessary, in which case the parties shall work in good faith to agree on such independent laboratory. The costs for any such independent laboratory API testing
shall be borne in the same manner as specified for API testing conducted by the independent expert. Hospira shall dispose of any nonconforming portion of any API shipment as directed by Cempra in writing, in accordance with the waste disposal
provisions of Section 5.8 and Cempra’s material safety data sheet (“MSDS”) for the Drug and at Cempra’s reasonable expense.

 (b) Title. Notwithstanding the DDP shipping terms of Section 5.4(a)(i),
Cempra shall retain title to the API while it is in the Hospira facility. Subject to the limitation in Section 5.4(c), Hospira shall assume responsibility and risk for, and exercise Commercially Reasonable Efforts in, the safekeeping,
storage and handling for all shipments of API delivered hereunder and accepted by Hospira. 
 (c) Loss and Replacement of API.
In the event of loss, waste, or damage of any API delivered hereunder or the failure of Product to meet Product Specifications, Cempra shall supply to Hospira replacement API according to the terms set forth in Section 5.4(a), except as
otherwise provided herein. If the replacement of such API results from a breach of this Agreement, failure to comply with GMP, Applicable Law, or the Product Specifications, or any negligent act or willful omission by Hospira or any Affiliate
thereof (or any employee, agent, or other representative of either of the foregoing) in the manufacture, handling or storage of Product or API, Cempra shall supply to Hospira replacement API and Hospira shall be responsible for the cost of the
replacement API equal to Cempra’s purchase cost/kg (as evidenced by Cempra’s invoices). Hospira shall issue Cempra with a credit note (applicable against any amounts due Hospira hereunder) equivalent to the cost of the replacement API no
later than [*] days of the determination of Hospira’s liability for such replacement cost; provided, however, that, in the event of the termination or expiry of this Agreement prior to the application of the full amounts of all such
credit notes against amounts due Hospira hereunder, Hospira shall pay Cempra the balance remaining of any such credit notes within [*] days of such termination or expiry. 

(d) Maximum Liability. Notwithstanding any of the foregoing, in no event shall Hospira’s liability for such replacement
costs of API exceed (i) [*] Dollars ($[*]) [*], or (ii) [*] Dollars ($[*]) [*]. This Section 5.4(d) states Cempra’s sole remedy, and Hospira’s sole liability, with respect to any claim arising hereunder for any such
loss, damage, or waste of API by Hospira. 
 5.5 Facility; Dedicated Equipment. 

(a) Maintenance of Facility. Hospira shall secure and maintain in good order, at its sole cost and expense, such current
governmental registrations, licenses and permits as are required by Regulatory Authorities in order for Hospira to perform all of its obligations under this Agreement and to manufacture the Product in accordance with Cempra’s purchase orders
therefor. 
 (b) Dedicated Equipment. At present, the parties anticipate that no specialized or dedicated equipment
(“Dedicated Equipment”) will be required of Hospira to manufacture Product for Cempra. In the event that the parties agree to make changes, either to the Product Specifications or to the scope of work as currently described
in the Project statement of work, and such changes would require Hospira to use Dedicated Equipment in the manufacture of the Product, Hospira and Cempra shall meet and discuss the methods, means and costs for acquiring, installing and validating
any such Dedicated Equipment and the responsibilities of the parties therefor. 
 [*] Confidential treatment requested; certain information omitted and

Applicable Law and (ii) any changes or supplements to such content, including the expense of securing any approvals required any applicable Regulatory Authority for any such changes or supplements. Hospira shall be responsible for obtaining
such labels (and any changes or supplements thereto) and packaging in accordance with content specified by Cempra. 
 (b) Should Cempra
request or be required to make any modifications to Product labeling and/or packaging, it shall submit a written change order to Hospira containing the requested or required modifications, together with any documentation specifying the content of
the new labeling and/or packaging, including all necessary photo-ready art (or its substantial equivalent). Hospira shall promptly provide Cempra with a statement of charges for the work to be performed based on its customary per/hour, per/person
rates then in effect and its estimated timeline for implementing the changes. Upon written approval by Cempra, which approval shall not be unreasonably withheld, delayed, or conditioned, Hospira will perform all requested or required labeling and
packaging work. Cempra shall pay Hospira for the work performed pursuant to the approved charges, in addition to reimbursing Hospira for the cost of any existing labeling and packaging that has become obsolete as a result of such changes. 

5.8 Off-Site Waste. If necessary, Hospira shall hire, direct and pay all costs for a waste contractor to remove all Waste from
Hospira’s manufacturing facility for Product consistent with the Product’s MSDS. Hospira shall only dispose of Specially Regulated Waste at sites and through waste management vendors that have been approved in writing by Cempra, whose
approval shall not be withheld unreasonably. Hospira shall document the destruction of any Specially Regulated Waste in writing and provide copies of such written documentation to an authorized representative of Cempra. Cempra maintains the right,
but not the obligation, to witness the actual disposal of Specially Regulated Waste. Cempra shall, upon request by Hospira, provide the MSDS for the API and the MSDS for the Product to Hospira.

Cempra in the preparation of any required export documentation. 
 5.10 Price and Payment. 

(a) Product Pricing. Hospira shall invoice Cempra for Product it delivers to Cempra at the [*] price(s) as set forth in the
pricing tables on Exhibit 5.10. Each invoice shall reference the price of the Product in effect on the date of Hospira’s invoice. All pricing is firm through December 31, 2013. Beginning January 1, 2014 and on each succeeding
January 1st thereafter during the Term, Hospira shall have the right to increase the price(s) of the Product once annually. Price increases shall be effective for deliveries beginning
January 1st of each calendar year. Such increases shall not exceed the lesser of (i) the amount of any actual increases in Hospira’s manufacture of Product or (ii) an amount
equal to the annual percentage increase for the most recent twelve (12) month period for which figures are [*]. Hospira shall use all Commercially Reasonable Efforts to provide written notice to Cempra of any anticipated price increase no later
than October 31st of any calendar year. 
 (b) Pricing
Reconciliation. Within [*] days after the close of any Commercial Year in which Cempra has ordered Product for delivery in such Commercial Year [*] the parties will jointly conduct a reconciliation process under which adjustments to the
price previously applied to Hospira’s commercial Product invoicing will be made to determine the credit amount that may be due to Cempra (and which can be applied by Cempra to any then-current or future amounts due Hospira), such that the
amount of such credit will equal the difference between the total amount paid (or owed) by Cempra based on the prices invoiced at the time of delivery and the amount that would have been paid or owed Hospira had the price charged for all units
delivered in such Commercial Year equaled [*] for each Product and batch size based on the unit volumes thereof ordered for delivery in such Commercial Year. For illustrative purposes, [*] 

[*]

 (d) Taxes; Fees. Cempra shall pay all federal, state, county or municipal sales or
use tax, excise, customs charges, duties or similar charge, or any other tax assessment (other than that assessed against income or any similar tax assessed or imposed on Hospira), lawfully assessed or charged on the manufacture or sale of the
Product that Hospira manufactures, sell and delivers pursuant to this Agreement. In particular, Cempra shall be responsible for and pay all Prescription Drug User (PDUFA) annual establishment fees imposed on Cempra with respect to the Product.
Cempra shall provide Hospira with copies of any tax exemption form(s) or similar documentation if it intends to claim exemption for taxes or similar charges in any state(s) (in the U.S.) or other jurisdictions where the Product is to be shipped.

 5.11 Inspection; Nonconforming Product. 

(a) Documentation; Inspection. Upon completion of the manufacture of each batch of Product, Hospira will provide Cempra with a
Certificate of Analysis confirming that the batch was manufactured in conformity with the Product Specifications, cGMP, and all Applicable Laws. In addition, Hospira will provide Cempra with a copy of the Master Batch Record and all other documents
and records as required by the Quality & Technical Agreement for Cempra’s (or its Affiliates’, or Cempra’s or its Affiliates’ licensees’, or sublicensees’) release of the batch and such samples of the batch
that Cempra may reasonably request. Cempra shall have a period of thirty (30) days from the date of its receipt of all such documentation (and if, applicable, batch samples) to inspect, and accept or reject, the corresponding batch as
conforming or non-conforming with the Product Specifications. If Cempra rejects the batch, it shall promptly so notify Hospira. If, as a result of further review and testing, Hospira determines that the Batch does conform to the Product
Specifications, Hospira shall so notify Cempra and the parties shall then submit samples of such batch to a mutually acceptable independent, neutral expert for testing. 

(b) Testing. If such independent, neutral expert determines that the batch conforms to the Product Specifications, Cempra shall
bear all reasonable, documented expenses of shipping and testing such batch samples and Cempra shall be responsible for Hospira’s invoice price of the batch. If such independent expert confirms that the batch does not meet the Product
Specifications, Hospira shall bear all reasonable, documented expenses of shipping and testing the batch samples. Notwithstanding the foregoing, the independent expert may also determine that additional sample testing by an independent laboratory is
necessary, in which case the parties shall use good faith efforts to agree on such independent laboratory and the allocation of the costs thereof. Absent error, negligence, and misconduct, the test results of the independent expert (or those of the
independent laboratory, if so referred by the expert) shall be binding on the parties. 
 (c) Replacement; Disposition of Rejected
Product. If a batch is rejected due to Hospira’s actual failure to manufacture, store, or handle the Product in conformity with the Product Specifications, cGMP, and all Applicable Laws, then Hospira shall (i) reimburse Cempra for
its actual cost/kg of the API used in the manufacture of such Product, subject to the limitations set forth in Section 5.4(d), and (ii) Hospira will use all Commercially Reasonable Efforts to replace the portion of any batch which
does not conform to the Product Specifications, cGMP, and Applicable Law with Products manufactured in accordance with the Specifications, cGMP and Applicable Laws as soon as reasonably practicable, given manufacturing capacities and


  
 Page 16 








 
scheduling at the Facility; provided, however, that (A) to the extent necessary to manufacture any such replacement Product, Cempra provides sufficient replacement API to Hospira in
accordance with the provisions of Section 5.4(c), and (B) in the event of any termination or expiry of this Agreement prior to start of manufacturing of any lot or batch of such replacement Product, Cempra shall be entitled, upon
Cempra’s election and written request, to receive from Hospira, in lieu of such replacement, a prompt refund of any amount paid with respect to the nonconforming Product. Hospira shall, as directed by Cempra, dispose of any rejected Products at
Hospira’s own cost and expense in accordance with the waste disposal provisions of Section 5.8 and Cempra’s MSDS for the Drug and the Product. 

(d) Deemed Acceptance; Latent Defects. Any Product that Cempra does not reject pursuant to this Section 5.11 shall be
deemed accepted, and all claims with respect to Product not conforming with Product Specifications are waived by Cempra, except as to latent defects which are not reasonably discoverable by the exercise of ordinary diligence by reasonable visible
inspection and other testing, if any, as agreed by the parties in the Quality & Technical Agreement to be part of Cempra’s inspection and acceptance process for Product after delivery by Hospira, render the Product not conforming to
Product Specifications, cGMP, and Applicable Law, and are primarily caused by negligence, fault, failure to comply with Applicable Law or cGMP, or failure to manufacture Product in accordance with the Product Specifications and Manufacturing Process
on the part of Hospira (or any Affiliate thereof or Third Party contractor supplier of Hospira or any Affiliate thereof). The parties shall consult in good faith to attempt to confirm the cause of the latent defect. If the parties do not agree as to
whether the Product is non-conforming, they shall submit samples of such Product for independent testing in accordance the provisions of Section 5.11(b). If it is confirmed that the cause of the latent defect is primarily attributable to
Hospira (or any Affiliate thereof or Third Party supplier or contractor of Hospira or any Affiliate thereof) consistent with the foregoing, then Hospira will promptly replace at no cost to Cempra all such non-conforming Products with Products that
meet the Product Specifications and are manufactured in accordance with cGMP and Applicable Law, subject to the provisions of Sections 5.4(c) and (d); provided, however, that in the event of any termination or expiry of
this Agreement prior to start of manufacturing of any lot or batch of such replacement Product, Cempra shall be entitled, upon Cempra’s election and written request, to receive from Hospira, in lieu of such replacement, a prompt refund of any
amount paid with respect to the nonconforming Product. All other relevant provisions of this Section 5.11 shall apply to the testing and release of such replacement Products. 

5.12 Miscellaneous. 

(a) Rework. Rework that becomes necessary as a result of changes proposed or required by Cempra shall be billed separately at a
commercially reasonable fee to be mutually agreed between the parties in writing. 
 (b) Sub-Lots. Should Cempra desire Hospira
to split a manufacturing lot of Product into up to two (2) sub-lots during packaging, Hospira will charge a split fee of [*] Dollars ($[*]) for each sub-lot packaged. Should Cempra request more than two (2) sub-lots per batch, the parties
will discuss and agree to more reasonably cost-effective alternatives. 
 [*] Confidential treatment requested; certain information omitted and filed

 (c) Storage Fee. Cempra will use Commercially Reasonable Efforts to take delivery
of the Products from the Facility no later than [*] days after full release and clearance of the Products. A storage fee of [*] Dollars ($[*]) [*] shall be due and payable to Hospira if Cempra stores Product at the Facility for more than [*] days
after the date of Hospira’s notice to Cempra that such Product is available for delivery; [*]. 
 ARTICLE 6.
ORDERS AND FORECASTS 
 6.1 Three Year Product Supply Forecast. For capacity
planning purposes, no later than [*] months in advance of Cempra’s anticipated date of initial Regulatory Approval or Cempra’s desired commercial Product availability date, Cempra shall provide Hospira with a non-binding, written forecast
of its estimated annual requirements of Product for the first three (3) Commercial Years. Thereafter, by [*] of each Commercial Year, Cempra shall update this three (3) year forecast for the three (3) year period commencing on
January 1st of the next Commercial Year. Within [*] days after receipt of each such forecast, Hospira shall provide Cempra with (a) a written acceptance of each Commercial Year’s estimate contained within such forecast and accordingly
plan to allocate its Facility capacity to manufacture Product for Cempra for each such Commercial Year, or (b) a written rejection of one (1), two (2), or three (3) of the Commercial Year estimates set forth in such forecast and written
acceptance of the Commercial Year estimates in such forecast that it did not reject; [*] Any written acceptance of the estimated amount for a particular Commercial Year shall constitute Hospira’s Product supply commitment (“Product
Supply Commitment”) for such Commercial Year and Hospira shall, notwithstanding anything to the contrary, be obligated to supply Product up to such amount to Cempra, but only to the extent of Cempra’s compliance with the
forecasting and ordering provisions set forth in this Agreement. If Cempra delivers, and Hospira accepts, as part of a subsequent three (3) Commercial Years forecast an updated forecast for any Commercial Year covered in a previously-provided
forecast hereunder, such subsequent forecast shall constitute Hospira’s Product Supply Commitment for such previously covered Commercial Year and be subject to Hospira’s supply obligations above. If Hospira rejects any Commercial Year
forecast as set forth above, (y) Hospira and Cempra shall meet as soon as possible to discuss in good faith the quantities of Product that Hospira could provide during such Commercial Year and the reasons for such rejection, and (z) use
Commercially Reasonable, good faith efforts to agree in writing on the amount that shall be Hospira’s Product Supply Commitment for such Commercial Year and be subject to Hospira’s obligation above. To the extent that Cempra’s Product
requirements in any Commercial Year exceed Hospira’s Product Supply Commitment therefor, Cempra shall have the right to have such excess requirements manufactured by Cempra, any Affiliate thereof, or any Third Party, without breach of
Section 5.1. 
 6.2 First Purchase Order. The parties shall cooperate in estimating and scheduling production for
Cempra’s first commercial order of Product, which in any case Cempra shall use Commercially Reasonable Efforts to place no later than [*] months in advance of the anticipated date of Regulatory Approval or Cempra’s desired commercial
Product availability date. 
 [*] Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 Page 18 








 6.3 Rolling Forecast. Concurrent with the placing of its first commercial order of
Product, and during each calendar quarter thereafter, Cempra shall provide to Hospira a good faith, estimated rolling forecast of the quantity of Products that Cempra expects to order for the coming [*] [*] period of time (each, a
“Rolling Forecast”). The first [*] [*] of each Rolling Forecast shall be considered a binding commitment upon Cempra to purchase quantities described therein and a binding commitment upon Hospira to produce and deliver such
quantities on the delivery dates described therein (“Firm Order Period”). The last [*] [*] of each Rolling Forecast shall be non-binding upon the parties. The Project Managers, or their designees, shall review each Rolling
Forecast to ensure that each Rolling Forecast delivered by Cempra is consistent with the requirements of this Agreement and, if necessary, to use good faith efforts to adjust such Rolling Forecasts in order to meet Cempra’s ongoing requirements
for the Product and to take into account Hospira’s manufacturing schedule at the Facility. 
 6.4 Purchase Orders. Cempra
shall submit to Hospira firm purchase orders for the purchase of Product (each, a “Purchase Order”) for the quantities of Product Cempra intends to purchase and the required delivery date(s); provided, however, that no
delivery date in any Purchase Order is either (a) less than [*] days from [*], or (b) [*] days prior to the requested delivery date. Hospira shall use Commercially Reasonable Efforts to meet the delivery dates set forth in each Purchase
Orders. All Purchase Orders shall reference this Agreement and shall be governed exclusively by the terms contained herein. Cempra shall set forth in each Purchase Order (w) the quantity of Product ordered, (x) the amount of API estimated
to be required to fill the Purchase Order (based on yield information provided by Hospira), (y) the specified delivery date(s) and delivery instructions, and (z) the price to be paid for the Product. 

6.5 Purchase Order Acceptance. Hospira will confirm each Purchase order issued in accordance with Section 6.4 within
[*] Days after receipt and shall confirm to Cempra its acceptance of the Purchase Order, delivery date(s), the quantity of Products ordered and the purchase price to be paid by Cempra. 

6.6 Excess Quantities. Hospira shall accept all Purchase Orders specifying quantities of Product up to [*] percent ([*]%) in
excess of the quantities listed in the corresponding Firm Order Period. Hospira shall not be obligated to supply quantities of Product over and above such [*] percent ([*]%) excess amount (“Non-Binding Excess”) but shall use
Commercially Reasonable Efforts to manufacture and deliver to Cempra all or part of the Non-Binding Excess within [*] days of issuance of the relevant Purchase Order. In no event, however, shall Hospira be required to supply any Product in excess of
its applicable annual Product Supply Commitment except to the extent any relevant Purchase Orders therefor are confirmed by Hospira. 
 6.7
Format of Forecasts and Purchase Orders. Cempra shall submit each Rolling Forecast and all Purchase Orders electronically in spreadsheet form and will specify the quantities of Products in units and the Hospira product number (list
number/inventory number). 
 6.8 Minimum Purchase Requirement. Cempra agrees to purchase from Hospira in each Commercial Year
not less than a stipulated percentage of its annual forecast of the Product in accordance with the provisions of this Section 6.8 (“Minimum Purchase Requirement”). The percentage shall be calculated on the number
of units of Product estimated to be required for delivery in a particular Commercial Year in the most recent annual forecast that Cempra provides 
 [*]

 Page 19 








 
to Hospira pursuant to Section 6.1. Cempra’s Minimum Purchase requirements are as follows: [*]. In lieu of Cempra taking delivery of all of the Minimum Purchase Requirement,
Cempra shall have the option to pay the shortfall of the Minimum Purchase Requirement at the prices set forth in Exhibit 5.10 and waive Hospira’s manufacture and delivery obligations for the Product. In the latter event, Hospira shall
invoice Cempra for the amount payable, and Cempra shall pay Hospira such amount within [*] days after receipt of Hospira’s invoice. Notwithstanding anything of the foregoing, all Product paid for by Cempra shall count towards the Minimum
Purchase Requirement and, in the event Cempra pays for all Product delivered by Hospira in a particular Commercial Year and the amount set forth above with respect to any waiver of Hospira’s manufacture and delivery obligations with respect to
such Commercial Year, Cempra shall be deemed to have satisfied its Minimum Purchase Requirement with respect to such Commercial Year. 
 6.9
Purchase Order Changes; Cancellations. 
 (a) Changes. If Cempra requests that changes be made to any of its
Purchase Orders within the Firm Order period, Hospira shall use Commercially Reasonable Efforts to accommodate such changes within reasonable manufacturing capabilities and efficiencies. If Hospira can accommodate such changes, but would incur
additional expenses in making such changes, Hospira shall advise Cempra of any costs associated therewith. If Cempra agrees in writing to accept these costs, Hospira will make the changes to the Purchase Orders and add the extra costs to the
relevant invoice. If Hospira cannot accommodate such change, Cempra shall nonetheless be bound to its original Purchase Orders. 
 (b)
Cancellations. If Cempra cancels any Purchase Order within the Firm Order Period, Hospira shall be relieved of its manufacturing obligations relating to such order; provided, however, that [*]. The foregoing provisions of this
Section 6.9(b) shall apply, mutatis mutandis, with respect to any Purchase Order to the extent that Cempra has not supplied sufficient API to allow Hospira to fulfill such Purchase Order or Cempra acts in any other manner that
effectively materially interferes with Hospira’s ability to fulfill such Purchase Order. 
 6.10 Shortage of Supply; Supply
Failure. In the event that Hospira is unable to manufacture and supply the Product in accordance with Cempra’s Purchase Orders, Hospira shall notify Cempra promptly in writing. 

(a) If such inability is not (i) caused by an event of force majeure, (ii) primarily attributable to Cempra’s acts or
omissions or breach of its obligations under this Agreement, or (iii) attributable in whole or in part to Component suppliers’ acts or omissions despite Hospira’s commercially reasonable efforts to obtain the relevant Components from
all approved suppliers for such Components, then Hospira shall be solely responsible for undertaking all commercially reasonable measures to minimize any possible shortage of Product to Cempra as a result of its manufacturing issues. If Hospira
cannot undertake such measures promptly, then either party may request that the Project Managers convene a meeting to discuss possible remedial action. 

[*] Confidential treatment requested; certain information omitted and filed separately with the SEC. 

  
 Page 20 








 (b) If such inability is due to Cempra not supplying sufficient Drug to allow Hospira to fulfill
any Purchase Order, then with respect to any Product is unable to manufacture and supply to Cempra as a result of such failure by Cempra, Cempra shall remain liable for the full amount of the Purchase Order, regardless of whether Hospira
manufactures the Product or whether Cempra takes delivery of the Product. 
 (c) If due to an inability to supply Product as described in
Section 6.10(a), Hospira delivers less than [*] percent ([*]%) of the number of units of Product ordered by Cempra within [*] days of the delivery date(s) specified in the most recent Rolling Forecast therefor in any [*] [*] periods
(“Supply Failure”), then [*]; and 
 (d) Cempra shall have the right to purchase all or a portion of its or its
Affiliates requirements of the Product from an alternative supplier, in each case until [*]. 
 (i) If, [*]. 

(ii) If [*].

promptly Cempra in writing (and in any event within [*] Days of discovery of any such failure), investigate such failure, and cooperate fully with Cempra in attempting to determine the cause of the failure. Hospira shall (a) keep Cempra
promptly informed in writing of the status of any such investigation, (b) [*], (c) promptly provide Cempra with copies of all batch records associated with such batch failure, to the extent reasonably requested by Cempra in writing, and
(d) upon completion of the investigation, shall provide Cempra with a final written report describing the cause of the failure and summarizing the results of the investigation. 

7.8 Product Recalls. 

(a) In the event (i) any Regulatory Authority or other national government authority issues a request, directive or order that the Product
be recalled, withdrawn, or the subject of a field correction (a “Recall”); (ii) a court of competent jurisdiction orders a Recall of Product; or (iii) Cempra or Hospira reasonably determines that Product should be

warranties under Sections 8.2(a) and 8.2(b), Hospira shall be responsible for, as elected by Cempra in writing (i) promptly replacing the quantity of Products that were Recalled at no cost to Cempra, or (ii) issuing a credit
to Cempra in the amount paid by Cempra with respect to such Product (which credit shall, to the extent not applied against amounts due Hospira hereunder, be promptly refunded to Cempra following termination or expiry of this Agreement). If Cempra

respect to any Recall, [*], but shall not be responsible for any lost profits, nor the cost to replace API to the extent such cost would be in excess of the limitations stated in
Section 5.4(d). In the event that the Recall does not result from the breach of Hospira’s express warranties or other obligations under this Agreement, Cempra shall be responsible for its reasonable, documented costs and expenses of
the Recall.

from the performance of the Project or manufacture of Product hereunder by Hospira, but only to the extent such Claims are not based on (i) the composition of matter of the Drug or, to the extent reflecting the portion of the Product
Specifications provided by Cempra (and not provided or proposed by Hospira), Product, (ii) the Manufacturing Process, or (iii) any process specifically proposed, or described in the portion of the Product Specifications provided by Cempra;

of or attributable to (a) any infringement of any Third Party Intellectual Property arising from the performance of the Project or manufacture of the Product hereunder by or on behalf of Hospira to the extent such Claims are based on
(i) the composition of matter of the Drug or, to the extent reflecting the portion of the Product Specifications provided by Cempra (and not provided or proposed by Hospira), any formulations thereof or Product, (ii) the Manufacturing
Process (or intermediates arising as a result thereof), or (iii) any process specifically proposed, or described in the portion of the Product Specifications provided, by Cempra; (b) personal injury, including death, caused by (i) the

representation made by Hospira in this Agreement. 
 8.6 Conditions of Indemnification. Each party’s agreement to
indemnify, defend, and hold harmless under Section 8.4 or 8.5, as applicable, is conditioned upon the indemnified party (a) providing written notice to the indemnifying party of any claim, demand or action arising out of the

non-indemnified liability on the part of the indemnified party without the prior written consent of the indemnified party. In the event the indemnifying party assumes control over the investigation of, preparation and defense against, and settlement
or voluntary disposition of any Claim, the indemnified party shall have the right, but not the obligation, to be represented by counsel of its own selection and at its own expense with respect thereto.

the Drug (or any analog(s) or derivative(s) thereof) (or the manufacture or use of any of the foregoing) or the Product (or the use thereof), or 

(ii) relates to the utility of the Drug or Drug Product: 

(all of the foregoing, “Cempra Improvements”) shall be the sole property of Cempra. Hospira shall, and does hereby, assign to Cempra,

all right, title, and interest therein (and in all intellectual property rights related thereto) to Cempra, free and clear of all liens, claims, and encumbrances. Hospira agrees to execute such assignments and other documents and to take such other
actions as may be reasonably requested by Cempra from time to time in order to effect to the ownership provisions of this Section 9.5. Upon Cempra’s request, Hospira will promptly provide Cempra with complete and accurate copies of
such Product Data. Hospira will not transfer, deliver or otherwise provide any such Product Data to any party other than Cempra, without the prior written approval of Cempra, unless required by Applicable Law in accordance with Article 11.
While in the possession or control of Hospira, the Product Data will be made available for inspection, examination and copying by or on behalf of Cempra, at Cempra’s sole cost and expense, during normal business hours and only upon reasonable
prior written request to Hospira. All original forms of Product Data relating to the manufacture of the Product hereunder, and any other records that are required to be maintained in compliance with cGMP or Applicable Law, will be retained and

laws, is dissolved or has a receiver appointed for substantially all of its property; or 
 (b) by giving to the other party [*] days’
prior written notice upon the breach of any warranty or any other material provision of this Agreement by the other party if the breach is not cured within [*] days after written notice thereof to the party in default; or 

(c) Upon [*] days’ written notice to the other party should the other party continue to be unable to perform its obligations under this

 10.5 Cempra’s Failure to Purchase Minimums. If, in any [*] consecutive
Commercial Years after the first Commercial Year, Cempra waives Hospira’s manufacturing and delivery obligations pursuant to Section 6.8, Hospira may terminate this Agreement upon [*] days prior written notice to Cempra given [*],
in which Cempra waived Hospira’s manufacturing and delivery obligations pursuant to Section 6.8. 
 10.6 Cempra
Termination Rights. In the event Cempra or any of its Affiliates licenses or grants a Third Party exclusive rights to sell, offer for sale, or otherwise commercialize one or more Products in one or more countries, then Cempra shall be
entitled to terminate this Agreement with respect to such Product(s) and country(ies) subject to such license or grant upon [*] written notice to Hospira; provided, however, that Cempra may not provide such written notice prior to the end of
the first (1st) Commercial Year. 
 10.7 Accrued Payment Obligations.
Upon termination pursuant to this Article 10, Cempra shall reimburse Hospira for Hospira’s reasonable, documented, direct cost of all Components purchased and on hand or on order, if such Components were ordered by Hospira based on Firm
Purchase Orders, and such supplies of Components cannot be reasonably used by Hospira for other purposes. Hospira shall invoice Cempra for all amounts due hereunder. Payment shall be made pursuant to Section 5.10(c). 

10.8 Return of Inventory and Dedicated Equipment. In the event of expiry or earlier termination of this Agreement, Hospira shall
return to Cempra, at Cempra’s option and request, all items of Dedicated Equipment (should it exist), and remaining inventory of API and Product at Cempra’s expense (which shall be reasonable and documented), unless termination shall have
been as a result of a breach of this Agreement by Hospira, in which case such Dedicated Equipment and inventory of API and Product shall be returned at Hospira’s expense. 

10.9 Return of Confidential Information. Upon expiry or termination of this Agreement for any reason, each party shall
immediately return to the other all of the other party’s Confidential Information, in any form or medium disclosed by the disclosing party (or upon a party’s instructions in writing, destroy the same and certify its destruction);
provided, however, that each party shall be allowed to retain one (1) copy of the other’s Confidential Information to ensure continuing compliance with Article 11. 

10.10 Survival. The expiry or earlier termination of this Agreement shall not relieve either party of any obligations that it may
have incurred prior to such expiry or earlier termination (including, with respect to any Purchase Orders placed by Cempra and confirmed or accepted by Hospira before such expiry or termination, satisfaction of such Purchase Orders in accordance
with, and subject to, the terms of this Agreement), and all covenants and agreements contained in this Agreement, which by their terms or context are reasonably intended to survive, including Article 1 and Sections 3.2, 4.2,

(b) Public Announcements. Neither party shall make any public announcement concerning the transactions contemplated herein, nor
make any public statement which includes the name of the other party or any of its Affiliates, or otherwise use the name of the other party or any of its Affiliates in any public statement or document, except as may be required by law, rule,
regulation, or judicial order, without the written consent of the other party, which consent shall not be unreasonably withheld. Notwithstanding the foregoing, Cempra may identify the other party to the this Agreement and disclose the terms of this
Agreement as reasonably necessary or useful in connection with the development, commercialization and/or divestiture or other disposition of the Product, subject to reasonable conditions of confidentiality, and either party may disclose the terms of
this Agreement subject to the following conditions: 

  
 Page 34 








 (i) to the extent such disclosure is required to comply with applicable laws, rules, or
regulations, including the rules and regulations promulgated by the United States Securities and Exchange Commission; provided, further, that prior to making any such disclosure, the party intending to so disclose the terms of this Agreement
shall, to the extent reasonably practicable, provide the non-disclosing party with reasonable prior written notice of the proposed disclosure and an opportunity to review and comment on the intended disclosure which is reasonable under the
circumstances; or 
 (ii) to the extent such disclosure is reasonably necessary in the following instances: to its Affiliates, and to
prospective and actual acquirers, merger or acquisition targets, licensees, sub-licensees, licensors, other strategic partners, employees, consultants, agents, accountants, lawyers, advisors, investors, lenders, and investment bankers, on a need to
know basis, each of whom prior to disclosure must be bound by written or professional ethical obligations of confidentiality and non-use substantially as restrictive in scope as those set forth in this Article 11 and that are of materially
similar or greater duration in view of the circumstances of the disclosure. 
 (c) Subject to any legal or judicial disclosure obligation,
any such public announcement proposed by a party that names the other party shall, to the extent reasonably practicable, first be provided in draft to the other party. 

11.3 Injunctive Relief. The parties acknowledge that either party’s breach of this Article 11 may cause the other
party irreparable injury for which it would not have an adequate remedy at law. In the event of a breach, the non-breaching party may be entitled to injunctive relief in addition to any other remedies it may have at law or in equity. 

ARTICLE 12. MISCELLANEOUS 

12.1 Force Majeure; Failure of Suppliers; Responsibility for Affiliates. 

(a) Excusable Delay. Neither party shall be considered to be in breach of this Agreement if a delay in the performance of any of
its duties or obligations hereunder (except the payment of money) has been caused by or is the result of an act of God, acts of a public enemy, insurrections, riots, embargoes, labor disputes, including strikes, lockouts, job actions, boycotts,
fires, explosions, floods, shortages of material or energy, or other unforeseeable causes beyond the reasonable control and without the fault or negligence of the party so affected (each, an event of “force majeure”). The
performance of the affected party shall be extended for a period equal to the period of such delay; provided, however, that the affected party shall give prompt written notice to the other party of such cause, and shall use Commercially
Reasonable Efforts to relieve the effect of such force majeure and resume compliance with this Agreement as soon as reasonably possible. Should the event of force majeure continue for a period longer than [*] days, the party not affected
thereby may terminate this Agreement in accordance with Section 10.4(c). 
 [*] Confidential treatment requested; certain information omitted
and filed separately with the SEC.

 (b) Transfer of Production. If Hospira becomes subject to an event of force
majeure which interferes with production of Product at the Facility, the parties shall use good faith efforts to mutually agree in writing on implementation of an agreed-upon action plan to transfer production of Product to another Hospira
plant. The parties shall, after the execution of this Agreement and at the written request of either party, meet to discuss and define such an action plan. 

(c) Responsibility for Affiliates. The acts and omissions of Cempra’s and Hospira’s respective Affiliates undertaking
any obligations or responsibilities under this Agreement shall be deemed the acts and omissions of Cempra and Hospira, respectively, and Cempra and Hospira, respectively, shall be liable and responsible therefor (including with respect to any breach
of this Agreement) as if such acts or omissions were those of Cempra and Hospira, respectively, hereunder.

writing and signed by authorized representatives of both parties. Failure by either party to enforce any such rights under this Agreement shall not be construed as a waiver of such rights, nor shall a waiver by either party in one or more instances
be construed as constituting a continuing waiver or as a waiver in other instances.
