event that as of the end of any Calendar Quarter during the Term commencing on or after January 1, 2010 (a “Covered Quarter”), Salix’s purchases of Compound pursuant to this
Agreement during such Calendar Quarter are less than the Salix Purchase Commitment in such Calendar Quarter, then Salix shall, within thirty (30) days following the end of such Calendar Quarter, pay to Lupin an amount equal to the product
obtained by multiplying (i) the difference between the Salix Purchase Commitment and Salix’s purchases of Compound pursuant to this Agreement during such Calendar Quarter by (ii) the Purchase Price. With respect to the Calendar
Quarter ending December 31, 2009, Salix shall, within thirty (30) days following the end of such Calendar Quarter, pay to Lupin an amount equal to (a)(i) Salix’s requirements for Compound in 2009 for the manufacture of Products for
sale in the Territory divided by (ii) eight (8) multiplied by (b) the Purchase Price; provided, that Salix may, at its election, make such payment prior to December 31, 2009 based on its reasonable estimate of its
requirements for 2009, so long as within thirty (30) days following the end of such Calendar Quarter it makes Lupin whole for any difference between such estimated requirements and Salix’s actual requirements for 2009. 
 (c) Lupin shall have the right, pursuant to and in accordance with Section 8.8, to audit Salix’s records to confirm
that Salix has made all payments required to be made by it by the provisions of clause (b).

 2.2 Forecasting, Order and Delivery of Compound. 
 (a) At least [*] ([*]) days prior to the first day of each Calendar Year during the Term, commencing with the
Calendar Year in which the Launch Date is anticipated to occur, Salix shall deliver to Lupin a written good faith forecast estimating, on a quarterly basis, the quantities of Compound that Salix expects to purchase from Lupin during such Calendar
Year (each, an “Informational Forecast”); provided that in the event that the Launch Date is anticipated to occur in Calendar Year 2009, Salix shall deliver to Lupin the Informational Forecast in respect of Calendar Year 2009
on a date reasonably agreed by the Parties. Each Informational Forecast shall be non-binding and shall be used by Lupin for planning purposes only. 
 (b) Commencing with a month that is at least [*] ([*]) months prior to the month in which
the Launch Date is anticipated to occur, on the fifteenth (15th) day of each month (or, at Salix’s discretion, at any time from the eighth (8th) day of such month up to and including the twenty-second (22nd
) day of such month), Salix shall deliver to Lupin a written good faith forecast estimating the quantities of Compound that Salix 
  
 * Confidential treatment requested; certain information omitted and filed

 7 








 
expects to purchase from Lupin for each month during the following [*] ([*]) months (each, a “Forecast”). The first [*] ([*]) months of each Forecast
shall be a “Firm Forecast”. Except as provided in clause (c) below, each Forecast shall be non-binding and shall be used by Lupin for planning purposes only. 
 (c) Without duplication of any previously delivered Purchase Order, each Firm Forecast shall be accompanied by a Purchase
Order for Compound to be delivered to Salix during each of the first [*] ([*]) months, respectively, set forth in such Firm Forecast. The quantity of Compound specified in any Purchase Order for delivery in any month (i) shall be
in multiples of the full production lots of Compound, such full production lot sizes to be mutually agreed following determination of the Specifications, (ii) shall not be more than [*] percent ([*]%) of the quantities specified
in the most recent Firm Forecast applicable to such month, and (iii) shall, unless otherwise agreed by Lupin in writing, be consistent with Lupin’s Current Capacity (or any increased capacity available to Lupin as of the Launch Date or as
subsequently agreed pursuant to a Scale-Up Plan). 
 (d) With respect to each Purchase Order, Salix shall be
obligated to purchase, and Lupin shall be obligated to deliver, by the required delivery date set forth therein such quantities of Compound as are set forth therein. In the event that the terms of any Purchase Order are not consistent with or are in
addition to the teens of this Agreement, the terms of this Agreement shall prevail. 
 (e) Lupin shall deliver
the quantities of Compound set forth in each Purchase Order by the required delivery date set forth in such Purchase Order [*] (as defined in Incoterms 2000) the port of entry designated by Salix; provided, however, that (i) Lupin

Compound from the Facility and (B) clearance of Compound through customs in the destination country and (iii) in the event any claim arises against any such carriage, insurance or other provider, Lupin, as promptly as possible, shall
assign such claim to Salix. All Compound shall be labeled in accordance with Applicable Law and packed for shipping in accordance with packing instructions provided by Salix. Title to and risk of loss of Compound shall pass to Salix at [*].

 (f) Each delivery of Compound shall be accompanied by (i) a Certificate of Analysis, (ii) a
Certificate of Compliance, (iii) such other documents as may be required pursuant to the Quality Agreement, and (iv) documentation necessary for the sale or export of the Compound. 
 2.3 Materials. 
 (a) Lupin shall maintain an inventory of Materials in sufficient quantities, and shall use commercially reasonable efforts to supply Salix with quantities

of Compound that are up to [*] percent ([*]%) of the quantities specified in each Firm Forecast. 
 (b) Lupin shall be responsible for auditing and qualifying its supplier(s) of Materials and obtaining supplies of Materials
in accordance with the Specifications. All Materials shall conform to the applicable specifications or Drug Master File, as further referenced in Regulatory Documentation owned or filed by or on behalf of Salix in respect of any Product. 

2.4 Invoice and Payment. Lupin promptly shall invoice Salix for all quantities of Compound delivered in accordance herewith.
Payment with respect to Compound delivered shall be due [*] ([*]) days after delivery to Salix of the invoice with respect thereto (which shall be deemed to be delivered as of the date of shipment, if delivered prior to shipment, and
shall be sent in electronic form contemporaneously with such delivery); provided that if Salix rejects such Compound pursuant to Section 2.7, then payment shall be due within [*] ([*]) days after receipt by Salix of notice
from the Testing Laboratory that the invoiced Compound is conforming or, subject to Section 2.7, receipt by Salix of replacement Compound, as the case may be; provided further that if Salix disputes any portion of an invoice, it shall
pay the undisputed portion and shall provide Lupin with written notice of the disputed portion and its reasons therefor, and Salix shall not be obligated to pay such disputed portion. The Parties shall use good faith efforts to resolve any such
disputes promptly. In the event of any inconsistency between an invoice and this Agreement, the terms of this Agreement shall control. Payment of invoices shall be made by wire transfer to an account designated in writing by Lupin in United States
Dollars. If any currency conversion shall be required in connection with any payment hereunder, such conversion shall be made each calendar quarter using an exchange rate that is the arithmetic average of the daily exchange rates (obtained as
described below) during such calendar quarter. Each daily exchange rate shall be obtained from The Wall Street Journal, Eastern United States Edition, or, if not so available, as otherwise agreed by the Parties. 
 2.5 Price. 
 (a) The purchase price (the “Purchase Price”) for all Compound to be delivered hereunder shall be determined as set forth in this Section 2.5. 
 (b) Beginning with Salix’s delivery of its first Forecast pursuant to Section 2.2(b) and continuing thereafter, the
Purchase Price shall equal [*] United States Dollars ($[*]) per kilogram of Compound. 
 2.6 Warranty. In
connection with each delivery of Compound to Salix hereunder, Lupin hereby represents and warrants to Salix as of the date of the delivery of such Compound to Salix as follows: (a) such Compound is in conformity with the Specifications and the

with the full quantity of Compound forecasted to be ordered or actually ordered by Salix in a timely manner and in conformity with the warranty set forth in Section 2.6 (whether by reason of force majeure or otherwise), Lupin shall, as promptly
as possible, notify Salix thereof (and, in any event, shall use commercially reasonable efforts to provide at least [*] ([*]) days’ advance notice thereof to Salix). Promptly thereafter, the Parties shall meet to discuss how Salix
shall obtain such full quantity of conforming Compound. Compliance by Lupin with this Section 2.7(a) shall not relieve Lupin of any other obligation or liability under this Agreement, including any obligation or liability under
Section 2.7(b), (c), or (d). 
 (b) If Lupin fails to deliver the full quantity of Compound specified in a
Purchase Order by [*] ([*]) days after the required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, (i) cancel all or any portion of such Purchase
Order, in which event Salix shall have no liability with respect to the portion of such Purchase Order so cancelled, or (ii) accept late delivery of all or any portion of the Compound specified in such Purchase Order. 
 (c) If Lupin fails to deliver the full quantity of Compound specified in a Purchase Order by [*] ([*]) days
after the required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, (i) cancel all or any portion of such Purchase Order, in which event Salix shall have no
liability with respect to the portion of such Purchase Order so cancelled, or (ii) accept late delivery of all or any portion of the Compound specified in such Purchase Order, in which event the Purchase Price otherwise payable by Salix with
respect to all Compound accepted by Salix under such Purchase Order shall be reduced by [*] percent ([*]%).

 (d) If Lupin fails to deliver the full quantity of Compound specified in a
Purchase Order by [*] ([*]) days after the required delivery date specified therein and in conformity with the warranty set forth in Section 2.6, then Salix may, at its option, (i) accept late delivery of all or any portion
of the Compound specified in such Purchase Order, in which event the Purchase Price otherwise payable by Salix with respect to all Compound accepted by Salix under such Purchase Order shall be reduced by [*] percent ([*]%) or
(ii) provide written notice to Lupin of its intention to qualify a third party manufacturer for the Compound, in which event Lupin shall use its commercially reasonable efforts promptly to assist Salix to qualify such third party manufacturer
designated by Salix to Manufacture the Compound, and shall promptly grant to such third party manufacturer, on a royalty-free, non-exclusive basis, such licenses, and provide to such third party manufacturer, free of charge, such technical
assistance, as such third party manufacturer may require in order to Manufacture the Compound to the then-current Specifications in accordance with the then-current Manufacturing process for the Compound, including full technology transfer of the
then-current Manufacturing process for the Compound, in all cases solely for the purposes of Salix’s production of Products. 
 (e) In the event that Salix determines, within [*] ([*]) days after delivery thereof by Lupin (or within [*] ([*]) days after discovery of any nonconformity that could not
reasonably have been detected by a customary inspection on delivery), that any Compound supplied by Lupin does not conform to the warranty set forth in Section 2.6, Salix shall give Lupin notice thereof (including a sample of such Compound, if
applicable). Lupin shall undertake appropriate evaluation of such sample and shall notify Salix whether it has confirmed such nonconformity within [*] ([*]) days after receipt of such notice from Salix. If Lupin notifies Salix that it
has not confirmed such nonconformity, the Parties shall submit the dispute to an independent testing laboratory or other appropriate expert mutually acceptable to the Parties (the “Testing Laboratory”) for evaluation. Both Parties
shall cooperate with the Testing Laboratory’s reasonable requests for assistance in connection with its evaluation hereunder. The findings of the Testing Laboratory shall be binding on the Parties, absent manifest error. The expenses of the
Testing Laboratory shall be borne by Lupin if the testing confirms the nonconformity and otherwise by Salix. If the Testing Laboratory or Lupin confirms that a lot of Compound does not conform to the warranty set forth in Section 2.6, Lupin, at
Salix’s option, promptly shall (i) supply Salix with a conforming quantity of Compound at Lupin’s expense or (ii) reimburse Salix for the Purchase Price paid by Salix with respect to such nonconforming Compound if already paid.
In addition, Lupin promptly shall reimburse Salix for all costs incurred by Salix with respect to such nonconforming Compound. Salix shall have the right to offset any such costs against any payments owed by Salix to Lupin under this Agreement.
Lupin immediately shall notify Salix if at any time it discovers that any Compound delivered hereunder does not conform to the warranty set forth in Section 2.6.

allow its Capacity to be less than the Current Capacity (or any increased capacity, to the extent Lupin has determined in its sole discretion to make it available as of the Launch Date, or as subsequently agreed pursuant to any Scale-Up Plans).
Without limiting the foregoing sentence, Lupin agrees that it will not at any time during the Term enter into any commitment to sell or otherwise supply Compound (or product containing Compound) to any third party that would cause its Capacity to be
less than the Current Capacity (or any increased capacity, to the extent Lupin has determined in its sole discretion to make it available as of the Launch Date, or as subsequently agreed pursuant to any Scale-Up Plans). 
 (c) In the event that at any time during the Term Salix contemplates that its annual requirements of the Compound are likely
to exceed the Current Capacity (or any increased Capacity as of such date), Salix shall promptly notify Lupin of that fact and the Parties shall thereafter discuss in good faith plans to increase Lupin’s Capacity in respect of the Compound so
as to meet Salix’s anticipated needs (as mutually agreed upon in writing, the “Scale-Up Plans”). Lupin agrees to implement any mutually agreed upon Scale-Up Plan as promptly as possible. 
 (d) As of [*] ([*])[*] prior to the Launch Date, Lupin shall provide Salix with a certificate that, to
the best of its knowledge, it will have sufficient Capacity as of the Launch Date to fulfill its supply obligations hereunder.

 24 








 
Losses each Party shall indemnify the other Party to the extent of its respective liability for such Losses. 
 7.2 Salix Indemnification. Salix shall indemnify Lupin, its Affiliates and its and their respective directors, officers, employees and agents (the “Lupin Indemnified Parties”), and
defend and hold each of them harmless, from and against any and all Losses incurred by any of them in connection with, arising from or occurring as a result of (a) the breach by Salix of any of its representations or warranties set forth in
this Agreement, (b) Salix’s material breach of this Agreement, (c) any Third Party Claim made by any Person that the Manufacture and supply of the Compound in accordance with the terms hereof infringes, misappropriates or otherwise
violates the patent, trademark or other intellectual property rights of such Person, (d) any Third Party Claim made by any Person relating to or arising out of death, personal injury, or other product liability, related to the marketing, sale,
distribution or use of the Compound or Product and caused by the negligence of Salix or its subcontractors or agents and (e) the enforcement by Lupin of its rights under this Section 7.2, except, in each case, for those Losses for which
Lupin has an obligation to indemnify the Salix Indemnified Parties pursuant to Section 7.1, as to which Losses each Party shall indemnify the other Party to the extent of its respective liability for such Losses. 
 7.3 Indemnification Procedure. 
 (a) Notice of Claim. The indemnified party (the “Indemnified Party”) shall give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an
“Indemnification Claim Notice”) of any Losses or discovery of facts upon which such Indemnified Party intends to base a request for indemnification under Section 7.1 or 7.2, but in no event shall the Indemnifying Party be
liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are
known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses. 
 (b) Third Party Claims. The obligations of an Indemnifying Party under this Article VII with respect to Losses arising
from claims of any third Person that are subject to indemnification as provided for in Section 7.1 or 7.2 (a “Third Party Claim”) shall be governed by and be contingent upon the following additional terms and conditions:

 (i) Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim by giving
written notice to the Indemnified Party within thirty (30) days after the Indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be
construed as an acknowledgment that the Indemnifying Party is liable to indemnify any Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any
Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected

  

 25 








 
by the Indemnifying Party, which shall be reasonably acceptable to the Indemnified Party. In the event the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party
shall immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Indemnified Party in connection with the Third Party Claim. Subject to clause (ii) below, if the Indemnifying Party
assumes the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the
Third Party Claim. In the event that it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend or hold harmless a Salix Indemnified Party or Lupin Indemnified Party, as applicable, from and against the Third Party
Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including reasonable attorneys’ fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defense of the Third Party
Claim with respect to such Salix Indemnified Party or Lupin Indemnified Party, as applicable. 
 (ii) Right to Participate in
Defense. Without limiting Section 7.3(b)(i), any Indemnified Party shall be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that
such employment shall be at the Indemnified Party’s own expense unless (A) the employment thereof has been specifically authorized by the Indemnifying Party in writing, (B) the Indemnifying Party has failed to assume the defense and
employ counsel in accordance with Section 7.3(b)(i) (in which case the Indemnified Party shall control the defense), or (C) the interests of the Indemnified Party and the Indemnifying Party with respect to such Third Party Claim are
sufficiently adverse to prohibit the representation by the same counsel of both parties under applicable law, ethical rules or equitable principles. 
 (iii) Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnified Party’s becoming
subject to injunctive or other relief or otherwise adversely affect the business of the Indemnified Party in any manner, and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party
hereunder, the Indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its sole discretion, shall deem
appropriate. With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 7.3(b)(i), the Indemnifying Party shall have authority
to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss; provided that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned
or delayed). The Indemnifying Party shall not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party
chooses to defend or prosecute any Third Party Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise or dispose of, any Third Party Claim without the prior written consent of the Indemnifying Party (which
consent shall not be unreasonably withheld, conditioned or delayed). 
  

 26 








 (iv) Cooperation. If the Indemnifying Party chooses to defend or prosecute any Third Party
Claim, the Indemnified Party shall cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as
may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are
reasonably relevant to such Third Party Claim, and making employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party shall reimburse
the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith. 
 (v) Expenses. Except as provided
above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim shall be reimbursed on a calendar quarter basis in arrears by the
Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to
indemnify the Indemnified Party. 
 7.4 Insurance. 
 (a) Each Party shall maintain (i) comprehensive general liability insurance with a combined single limit for bodily
injury and property damage of not less than [*] United States Dollars ($[*]) and (ii) product liability/completed operations coverage with a per claim limit of not less than [*] United States Dollars ($[*])
(collectively, the “Policies”). If any Policy is written on a claims-made basis, the retroactive date, if any, shall not be later than the Effective Date of this Agreement. In addition, such coverage shall be continued in full force
throughout the Term of this Agreement and for a period of [*] ([*]) years thereafter and neither Party’s Policies shall be canceled or subject to a reduction of coverage or any other modification without written notice to the
other Party. 
 (b) Each Party shall furnish certificates of insurance for its Policies to the other Party within
ten (10) days after the Effective Date. 
 7.5 Limitation on Damages. EXCEPT WITH RESPECT TO THE [*] OR
INTENTIONAL MISCONDUCT OF A PARTY, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS, WHETHER IN CONTRACT, WARRANTY,
NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE; PROVIDED, HOWEVER, THAT THIS EXCLUSION IS NOT INTENDED TO, NOR SHALL IT, EXCLUDE DAMAGES OWED TO THIRD PARTIES.

statement submitted under this Agreement. Such examinations may not (i) be conducted more than once in any [*] ([*]) month period (unless a previous audit during such [*] ([*]) month period revealed an underpayment

audited Party or any correction to statements submitted by the audited Party under this Agreement, as the case may be. Except as provided below, the cost of this examination shall be borne by the
auditing Party, unless the audit reveals a variance of more than five percent (5%) from the reported amounts, in which case the audited Party shall bear the cost of the audit. Unless disputed pursuant to Section 8.8(b), if such audit
concludes that additional payments were owed or that excess payments were made during such period, the audited Party shall pay the additional amounts, with interest from the date originally due as provided in Section 8.8(c), or the auditing

agency or other governmental entity in accordance with Applicable Law. 
 8.11 Assignment. Except as expressly provided
herein, neither Party may, without the prior written consent of the other Party, sell, transfer, assign, delegate, pledge, subcontract or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or

in and to the Compound or any

Product, (b) Lupin may, without such consent, assign this Agreement and its rights and obligations hereunder to one or more Affiliates, and (c) either Party may, without such consent,
assign this Agreement and its rights and obligations hereunder to the purchaser of all or substantially all of its assets or to any successor entity or acquirer in the event of a merger, consolidation or change in control of such Party. Any attempt
to assign, transfer, subcontract or delegate any portion of this Agreement in violation of this Section shall be null and void. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the
benefit of and be enforceable by and against the successors and permitted assigns of Salix or Lupin, as the case may be. In the event either Party assigns or delegates its rights or obligations to another Person in accordance with the terms hereof,
the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement and the assignor or transferor shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this
Agreement from and after the effective date of such assignment. No such assignment or delegation shall relieve the assignor or transferor of any of its obligations hereunder. Notwithstanding the foregoing, Lupin shall have the right, from time to
time and without the necessity of providing notice to or obtaining the consent of Salix, to delegate, assign, or subcontract to any Affiliate, certain of Lupin’s rights or responsibilities under this Agreement. In all cases, Lupin shall remain
the contract Party under this Agreement and shall remain responsible to Salix for the performance of all such obligations under this Agreement. 
 8.12 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a
written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by either Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the
same or any other term or condition of this Agreement on any future occasion. 
 8.13 Severability. If any provision of
this Agreement is held to be illegal, invalid or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision
shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full
force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of
this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties herein. 
 8.14 Independent Contractors. The status of the Parties under this Agreement shall be that of independent contractors. Nothing in
this Agreement is intended or shall be deemed to constitute a partnership, agency, employer, employee, or joint venture relationship between the Parties. Neither Party shall have the right to enter into any agreements on behalf of the other Party,
nor shall it represent to any Person that it has any such right or authority.
