(a) Subject to Section 3.4, the Purchase Price of the Plasma purchased by Buyer from the Seller pursuant to Section 4 of this
Agreement shall be *** per liter of Plasma. Beginning ***, the Purchase Price shall be increased automatically at the beginning of each calendar year by CPI. In addition, Seller or Buyer may propose an increase or decrease in the Purchase Price of
no more than *** based on current market conditions for the following calendar year. Such latter increase or decrease shall take effect only if approved by the other Party (such approval shall not be unreasonably withheld). Notwithstanding the
above, at no time shall the Purchase Price be less than ***. If one Party notifies the other Party of its intent to renew the Agreement beyond the Initial Term pursuant to Section 9.1 then the Parties shall meet within *** days of the receipt
of the notice to discuss in good faith the adaption of the Purchase Price to current market conditions.

(b) Seller shall
invoice Buyer for all Plasma at the time of delivery of such Plasma to Buyer. Buyer shall pay undisputed invoices within *** days from date of Sellers invoice. Such invoice shall not be dated or submitted prior to delivery of the underlying

(c) In the event of a change to the Specifications, new governmental regulations or FDA or EU required testing, which cause an increase
or decrease in Sellers Costs, the Parties shall work in good faith to re-negotiate the Purchase Price.

3.4 Refund of
Pre-Payments. Buyer shall be entitled to a credit of (i) *** per liter of Plasma delivered to Buyer from January *** and (ii) *** per liter of Plasma delivered to Buyer on or after *** until such time as the aggregate amount of such
credits equals the original Total Pre-Payments made by Buyer to Seller. In the event that this Agreement is terminated for any reason (except a termination of this Agreement by Seller pursuant to Section 9.2) at any time prior to Buyers
full utilization of the credits for the Total Pre-Payments and Buyer does not elect to exercise its Purchase Option, Seller shall within *** business days pay to Buyer an amount equal to any remaining amount of such Total Pre-Payments which has not

- 7 -



---

4.2 Plasma Volume after 2011. Beginning in 2012 and continuing
through the Term, Seller shall sell and Buyer shall purchase the Plasma quantities in a range of *** liters of Plasma on a calendar year basis. Not later than *** months prior to
January 1stof a calendar year, Buyer will provide
notification of the Plasma Volume required for that calendar year. The Parties will negotiate in good faith a mutually agreeable and reasonable delivery schedule. Seller shall provide the Plasma Volume regardless of the Plasma output at the New
Centers. Buyer shall have the right to request the Plasma Volume for any calendar year within a range of (i) *** liters if no Additional New Centers are open, (ii) *** liters if one (1) Additional New Center is open and (iii) ***
liters if two (2) Additional New Centers are open. In the event that Buyer requests the construction of an Additional New Center (but excluding, for clarity, any Initial New Center), then the Plasma Volume shall be increased by *** liters per
each Additional New Center and become effective for that calendar year following the new centers opening on a pro rata base (e.g. if the opening date is in May 2012, than range for 2013 will be increase by *** of *** liters). In the event that Buyer
and Seller consummate the purchase of all of the New Centers, then Buyer shall not be required to purchase any Plasma pursuant to this Agreement, once the Buyer owns all of the New Centers.

4.3 Plasma Source. Seller will supply and Buyer shall purchase Plasma collected at the Qualified Centers and/or Buyer Approved
Collection Centers only, subject to the terms and conditions of this Agreement. During the period of time that any New Center has not received all Regulatory Approvals and is therefore a Non-Qualified Center, Seller shall be solely responsible for
any plasma produced at such Non-Qualified Center. Under no circumstance is Buyer required to purchase plasma from any Non-Qualified Center(s) or Buyer Approved Collection Center that has not received all Regulatory Approvals. However, for avoidance
for doubt, and for clarification purposes once a New Center has received all Regulatory Approvals, any Plasma collected during the time the New Center was a Non-Qualified Center may be sold to Buyer pursuant to the terms and conditions of this
Agreement if and only if such Plasma has been licensed by the FDA and approved by the EU. For the purpose of this Agreement, a center is a Buyer Approved Collection Center if it is listed on Exhibit A. Buyer may add a collection center
to the list if: (i) the center has received and maintains as current all necessary regulatory approvals, registrations and permits including, but not limited to, FDA licensure, EU approval, iQPP, CLIA, and required state licensing;
(ii) the center has completed and Buyer has approved an affirmation of compliance, or the center has been audited by Buyer or its agents pursuant to Section 4.16 with no significant observations; (iii) the center satisfies the
requirements described in the Origin of Plasma section of the attached Specifications; and (iv) the center has been added to the list of Buyer Approved Collection Centers by Buyer, as set forth in Exhibit A. If any Buyer Approved
Collection Center (i) receives a significant enforcement correspondence from a governmental authority (ii) is identified by Buyer or its agents to have significant compliance or quality concerns during an audit under Section 4.16,
(iii) or Buyer determines that the plasma collection center is materially deficient in its compliance with applicable laws, regulations or quality requirement, Seller will have *** business days to provide, in writing, a corrective action plan
acceptable to Buyer. If the action plan is found unacceptable or if the Buyer Approved Collection Center cannot provide Plasma within *** days of any such event, then Buyer may modify Exhibit A to eliminate such Buyer Approved Collection Center
from the list Buyer and



- 8 -



---

Seller shall list Primary Buyer Approved Collection Centers and Secondary Buyer Approved Collection Centers on Exhibit A. Seller will supply Plasma to Buyer from the Qualified Centers and Primary
Buyer Approved Collection Centers only. To the extent that Seller is required to supply Plasma from Secondary Buyer Approved Collection Centers, Seller shall notify Buyer and request approval from Buyer, which shall not be unreasonably withheld.

4.4 Right of First Refusal of Seller. If Buyer requires, for a certain calendar year, any Plasma in addition to
(i) the then-current Plasma Volume supplied under this Agreement plus (ii) *** liters Buyer is currently contractually bound to purchase, on a notice period shorter than *** months, then Buyer, must first request an increase in the Plasma
Volume up to the maximum Plasma Volume set forth in Section 4.2 under the terms and conditions of this Agreement. If Seller agrees to provide the additional Plasma Volume in the requested time frame, then the Plasma Volume will increase by the
proposed amount and Buyer will purchase the additional Plasma from Seller in the requested time frame subject to the terms and conditions of this Agreement. If Seller does not agreed to provide the additional Plasma Volume within the requested time
frame, then, notwithstanding anything to the contrary in this Agreement, Buyer is permitted to purchase such additional Plasma from an Alternative Supplier. If the requirement exceeds the maximum Plasma Volume set forth in Section 4.2, then
Buyer shall provide Seller with a right of first refusal to supply such additional Plasma. Buyer will notify Seller in writing of any terms proposed by an Alternative Supplier and Seller will have *** business days to exercise its right of first
refusal. If Seller elects not to exercise its right of first refusal or fails to respond to buyers request or refuses to supply the requested additional plasma within such *** business day period to increase the Plasma supply, then Buyer may
purchase Plasma from the Alternative Supplier. Sellers failure to exercise its option at any time does not waive Buyers requirement to provide Seller with a right of first refusal for all future plasma needs during the Term of the
Agreement.

4.5 Hyperimmune Plasma Supply. So long as Seller is able to satisfy all requirements for Plasma pursuant to
this Agreement, Seller shall have the right to produce hyperimmune plasma in a New Center for Sellers own use; provided that (i) the volume of hyperimmune plasma does not exceed *** of the total volume, including Plasma and hyperimmune
plasma, produced at such New Center at any time and (ii) the production thereof in such New Centers is in compliance with all applicable Regulatory Approvals and Applicable Laws. Buyer shall not be required to purchase any hyperimmune plasma
nor continue any hyperimmune plasma program if Buyer purchases the New Centers.

4.6 Delivery. Except as otherwise
agreed in writing by the Parties, all deliveries of Plasma shall be ***. Buyer will arrange for a shipping agent or carrier to pick-up the Plasma at Sellers facility. The shipping agent or carrier shall be selected and contracted by Buyer.

4.7 Governing Documents. All sales of Plasma hereunder shall be subject solely to the terms and provisions of this
Agreement (including all exhibits and schedules) and shall not be subject to other terms, conditions or provisions contained in any other purchase order, writings, or documents except to the extent a purchase order, writing or document sets forth or
confirms quantity or schedule or place for delivery. Furthermore, in the event of any inconsistency or discrepancy between the terms and conditions of this Agreement and the schedules hereto, or any other record, the terms of this Agreement shall
prevail.

4.8 Records and Compliance Matters. Seller shall, at its expense, keep and maintain
detailed records pertaining to the amount and type of Plasma sold hereunder during the Term and for a period equal to the longer of: (a) *** following the date of termination or expiration of this Agreement; and (b) the period of time
required by the Applicable Laws. Such records shall be made available for inspection by Buyer during normal business hours, upon reasonable advance written notice, which shall not be less *** days (or such shorter period of time as may be mutually
agreed upon by the Parties). Seller shall transfer such records related to the New Centers to Buyer in connection with the consummation of the acquisition of the New Centers by Buyer as contemplated by this Agreement.

4.9 Licenses and Approvals. Seller use commercially reasonable efforts to obtain and maintain in full force and effect all
necessary licenses, permits, certifications, consents, licenses, registrations, listings, certificates of origin, and any other requisite documents and authorization, including approvals and registrations, and pay all applicable fees, charges,
customs duties and taxes incurred in the performance of its obligations under this Agreement, including with respect to all New Centers and Buyer Approved Collection Centers. Without limiting the generality of the foregoing, Seller use commercially
reasonable efforts to comply with all Applicable Laws, Regulatory Approvals, regulations, rules, and guidelines pertaining to its performances under this Agreement, including but not limited to those set forth in the U.S. Code of Federal
Regulations, 21 C.F.R. parts 600-640 and any other applicable local, state or federal law, regulation or ordinance.

4.10
Storage, Shipping and Handling of Plasma. Plasma shall be stored, handled, packed and shipped by Seller in such a manner as to prevent damage to the Plasma and containers during shipping, consistent with Sellers current practice and
otherwise in compliance with all Applicable Laws and Regulatory Approvals, and shall be stored, handled, packed and shipped (including to any holding facility designated by Buyer) subject to such other conditions set forth in the Specifications. No
Plasma shall be released by Seller to Buyer pursuant to this Agreement unless and until such Plasma fully complies with the Specifications, Applicable Laws and Regulatory Approvals, and Seller shall be responsible for ensuring compliance therewith.

4.11 Quality. Seller shall source, collect, process, store, distribute, test, transport, and otherwise handle Plasma,
to be sold to Buyer in accordance with this Agreement, at all times in compliance with all Applicable Laws, Regulatory Approvals and the Specifications. Any and all reasonable changes sought by Buyer to the Specifications shall be sent to Seller for
review and approval. Buyer shall advise Seller of any and all anticipated reasonable changes to Specifications as soon as practicable so as to provide Seller with as much advance notice as possible. Seller shall have *** business days to agree to
implement the changes or to respond to Buyer with its reasons for refusing to implement such changes. If Seller agrees to implement such changes, Seller shall implement such changes as promptly as reasonably possible, but in all cases within ***
days after receipt of written notice of such changes. For purposes of clarity, Seller shall not make changes to the process parameters or the Specifications without prior written approval of Buyer (in its reasonable discretion). Seller shall notify
Buyer immediately and in any event not later than *** business days after: (a) any

Existing Center (including without limitation, any Buyer Approved Collection Center) or New Center is closed as a result of regulatory sanctions placed on Seller by the FDA (or any foreign
equivalent) or any other governmental authority; (b) Seller or any New Center or Buyer Approved Collection Center becomes subject to a significant enforcement action from the FDA (or any foreign equivalent) or any other governmental authority;
(c) Seller or any New Center or Buyer Approved Collection Center fails an audit or inspection conducted by or on behalf of any governmental authority or any accrediting body; or (d) Seller otherwise learns of significant quality concerns
that may impact the safety or quality of the Plasma provided to Buyer. In the event that Seller notifies Buyer of any of the foregoing, or Buyer otherwise determines that any New Center or Buyer Approved Collection Center is deficient in its
compliance with Applicable Laws, Regulatory Approvals or Specifications, the Parties shall work in good faith to minimize overall shortfalls in quantities of Plasma delivered to Buyer, but any such shortfall shall remain the responsibility of
Seller.

4.12 Testing and Approval. Seller shall be responsible, at its sole cost and expense, for testing Plasma in
accordance with FDA and EMEA requirements and the Specifications. Seller shall be responsible for qualifying appropriate testing centers. Seller shall send all Plasma to be provided to Buyer pursuant to this Agreement only to Approved Testing
Centers. However, Seller may send Plasma to an alternative laboratory upon the approval of Buyer, which shall not be unreasonably withheld. With respect to each shipment of Plasma to be shipped to Buyer, Seller shall test such Plasma to ensure
compliance with the Specifications, Applicable Laws and Regulatory Approvals, and warranties as set forth in Section 8.2. Seller shall include a certificate of analysis and certificate of compliance, as well as all other documentation described
in the Specifications, with each shipment of Plasma disclosing the results of such testing and certifying conformance with the Specifications and other requirements. Buyer may reject any Plasma after review of the accompanying documentation or upon
inspection after receipt by Buyer or Buyers designee if such Plasma is not in compliance with the Specifications or any warranty hereunder. Buyer shall *** each shipment of Plasma received from Seller and the associated documentation and shall
notify Seller in writing in the event of Buyer intends to rejects such shipment within *** business days after receipt. In the case of Plasma with defects not readily discoverable during inspection upon receipt by Buyer, Buyer shall notify the
Seller of such defects *** following Buyers discovery thereof and shall be entitled to reject such Plasma. Rejected Plasma will be destroyed in compliance with Buyers internal procedures and local environmental requirements. Seller
reserves the right to *** the *** concerning the *** of ***.

4.13 Remedies For Non-Conformity. In the event that

9.4 Effect of Termination. In the event of any termination or expiration of this Agreement, all further obligations by the Parties
with respect to the purchase and sale of Plasma (including, for clarity, any Plasma Volume obligations imposed on Buyer), as well as the construction, operation and sale of the New Centers shall immediately expire, and the Parties shall have no
further obligation to proceed with any transactions with respect to such matters (except pursuant to any management agreement executed in connection with the purchase of a New Center or any New Center Purchase Agreement which has not been
consummated to the extent Buyer and Seller elect to continue such transaction. The rights and remedies available to Buyer or the Seller are as set forth in this Agreement and shall not preclude or dismiss Buyers or the Sellers right to
pursue any other or additional right or remedy, including, without limitation, any claim for damages against any third party in connection with this Agreement. The failure to exercise any right or remedy in the event of any breach or default shall
not constitute a waiver or adversely affect Buyers or the Sellers right to exercise any right or remedy under this Agreement.

9.5 Provisions Surviving Termination. Termination or expiration of this Agreement shall not relieve the Parties hereto of any obligation accruing prior to such termination or expiration. The
provisions of this Agreement which by their nature would continue beyond any termination or expiration of this Agreement, including Section 8, Section 9, Section 10, Section 11, Section 12, Section 13, Section 14

of this Agreement all prior agreements for the purchase and sale of Plasma between Buyer and Seller are hereby terminated in all respects, other than any provisions of any such agreement whose terms specifically survive termination; provided,
however that this Section 9.6 shall not apply to (i) ***, and (ii) ***. This Agreement does not affect any agreements between Biotest AG and Buyer or Buyers Affiliate(s).

Section 10. Indemnity.

10.1 Indemnification. The Seller and Buyer
hereby indemnify and agree to hold harmless each other and its respective affiliates, agents, employees, officers and directors, from and against any and all claims, losses, liabilities, damages, attorneys fees, costs and expenses which may be
sustained by and/or claimed against the other Party by virtue of the gross negligent performance of services rendered by the other Party, the willful misconduct by the other Party or its officers, employees or agents, or any representation or
warranty contained in this Agreement being breached, untrue or materially misleading by omission or otherwise. It being understood, however, that the financial liability under this section shall be limited to the extent of each Partys
insurance coverage, if such coverage is in effect and in accordance with any requirements under this Agreement at the time a claim is asserted under this section.

10.2 Defense and Settlement. The obligations to indemnify, defend and hold harmless set forth in this section shall not apply to the Party to be indemnified (the Indemnified Party)

knowledge; (ii) gives the Indemnifying Party, at the Indemnifying Partys option, the full opportunity to control the response thereto and the defense thereof, including any agreement relating to the settlement thereof, provided that the
Indemnifying Party shall not settle any such claim or action without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed) or such settlement include as an unconditional term thereof the
giving by the claimant of an unconditional release from all liability in favor of the Indemnified Party; and (iii) cooperates with the Indemnifying Party, at the Indemnifying Partys cost and expense, in the defense or settlement thereof.

Indemnified Party may, at its own expense, participate in its defense if any claim.

Section 12. Confidentiality.

12.1 During the Term and for a period of *** years thereafter, each Party shall (i) hold the other
Partys Confidential Information in strict trust and confidence and avoid the disclosure or release thereof to any other person or entity by using at least the same degree of care as it uses to avoid unauthorized use, disclosure, or
dissemination of its own Confidential Information of a similar nature, but not less than reasonable care, (ii) not use the other Partys Confidential Information for any purpose whatsoever except as expressly contemplated under this
Agreement, and (iii) not directly or indirectly, copy, reproduce, use, publish, misappropriate, assign, or otherwise transfer or disclose to any person the other Partys Confidential Information, other than as permitted pursuant to the
terms of this Agreement, regardless of whether such information was actually delivered to the receiving Party prior to the effective date of this Agreement. Confidential Information, as used herein, shall mean all information, trade
secrets, inventions, data, processes, or other records relating to a Partys business, financial affairs or operations, including but not limited to information related to business plans, technology, source code, product or service
requirements, customers, pricing, techniques and methods, which is either marked or identified as confidential or which the receiving Party knew or reasonably should have known, under the circumstances, was confidential, whether disclosed in any
tangible, electronic, visual or other medium. Confidential Information shall also include all information, know-how, trade secrets, data (technical or non-technical) or other confidential information concerning the operations, projects,
organization, business or finances of a Party or any third party to which a Party owes a duty of confidentiality, in whatever form, that a receiving Party learns, generates or acquires in conjunction with the performance of the services pursuant to
this Agreement. All files, records, documents, notes, or other items relating to or embodying



- 24 -



---

Confidential Information that may be delivered to a receiving Party or to which a receiving Party may be granted access, shall remain the exclusive property of the Party disclosing such
Confidential Information. Neither Party shall disclose to any third parties, including a customer of the other Party, the existence or terms of this Agreement. For purposes of clarity, all information relating to any New Center shall be deemed to be
the Confidential Information of Buyer from and after the consummation of the acquisition of such New Center by Buyer. On either Partys request upon the termination or expiration of this Agreement, the other Party shall immediately:
(i) stop using the Confidential Information of the requesting Party; (ii) return all materials provided by the requesting Party that contain Confidential Information of the requesting Party, except for one copy that may be retained by the
other Partys legal counsel to confirm compliance with the obligations under this Agreement; (iii) destroy all copies of Confidential Information of the requesting Party in any form, including materials prepared by or for the other Party
and Confidential Information contained in computer memory or data storage apparatus or materials prepared by or for Seller; and (iv) provide a written confirmation to the requesting Party that such other Party has taken all the foregoing
actions.

12.2 A receiving Party shall not disclose any Confidential Information except to its officers, directors,
employees and authorized representatives, and its Affiliates and their respective officers, directors, employees and authorized representatives (collectively Representatives) who need to know such information for the purpose of
performing the services contemplated by this Agreement and which persons shall be similarly bound in writing (it being understood that each such Representatives shall be informed by the receiving Party of the confidential nature of such material and
shall be directed to treat such material confidentially in accordance with the terms of this Agreement). A receiving Party agrees to be responsible for any breach of this Agreement by any of its Representatives. Notwithstanding the foregoing, a
receiving Party shall not be required to maintain confidentiality with respect to information (i) which is or becomes part of the public domain not due to any act or omission by the receiving Party; (ii) of which it had independent
knowledge without confidentiality restriction prior to disclosure by the disclosing Party, as shown by written evidence; (iii) which comes into the possession of the receiving Party (without confidentiality restriction) in the normal and
routine course of its own business from and through independent, non-confidential sources, as shown by written evidence;; or (iv) which is required to be disclosed by receiving Party governmental requirements. If receiving Party is requested or
required (by oral questions, interrogatories, requests for information or document subpoenas, civil investigative demands, or similar process) to disclose any Confidential Information supplied to it by the disclosing Party, the receiving Party
shall, if possible, immediately notify the disclosing Party of such request(s) prior to any disclosure so that the disclosing Party may seek an appropriate protective order. Seller acknowledges that Buyer may be required to (and shall be permitted
to) disclose the terms of this Agreement pursuant to its reporting obligations under the Securities Exchange Act of 1934, as amended (or other securities exchange requirements), and to file a copy of this Agreement as an exhibit to a periodic,
quarterly or annual report required to be filed by Buyer thereunder.

12.3 Failure on the part of the receiving Party
to abide by this Section 12 may cause the disclosing Party irreparable harm for which damages will not be an adequate remedy at law. Accordingly, the non-breaching Party has the right to seek injunctive relief to prevent any threatened or
actual violations of this section in addition to whatever remedies it may have at law, In such a proceeding, the Party allegedly breaching this Agreement expressly waives the defense that a remedy in damages will be adequate and any requirement in
an action for specific performance or injunction for the posting of a bond by the non-breaching Party.

Section 13. Force Majeure. Neither Party will be liable for any default or delay in the performance
of its obligations under this Agreement if and to the extent such default or delay is caused, directly or indirectly, by fire, flood, elements of nature or other acts of God, epidemics, any outbreak or escalation of hostilities, war, terrorism,
riots or civil disorders, strikes or work stoppage, utility or telecommunications failures or fluctuations, proclamation, regulation, or ordinance or other act to order of any court, government or governmental agency or any other similar cause
beyond the reasonable control of such party, except that each Party shall be responsible for the timely payment of all of its financial obligations to the other Party. In any such event, the non-performing Party will be excused from any further
performance and observance of the obligations so affected only for as long as such circumstances prevail and as long as such Party continues to use commercially reasonable efforts to recommence performance or observance as soon as practicable.

Section 14. Additional Agreements between the Parties.

14.1 Notifications. The Buyer, on the one hand, and the Seller, on the other hand, shall promptly notify the other of any action, suit or proceeding that shall be instituted or threatened against
such Party to restrain, prohibit or otherwise challenge the legality of any transaction contemplated by this Agreement. Each Party will give prompt written notice to the other Party of any material adverse development causing a breach of any of its
own representations and warranties in this Agreement. No disclosure by any Party pursuant to this Section, however, shall be deemed to prevent or cure any misrepresentation, breach of warranty, or breach of covenant.

14.2 Non-Competition. During the Term of this Agreement and for a period of *** years after any termination or expiration of this
Agreement or the Management Agreement, whichever is longer, except for a termination based on the breach of this Agreement by Buyer, Seller agrees that it will not directly enter into or become associated with or otherwise operate any plasma
collection centers within a radius of *** miles from the location of any New Center.

14.3 Non-Solicitation. During the
Term, and the term of the Management Agreement, and for *** years thereafter, the Parties shall not, directly or indirectly hire or attempt to hire any employee of the other Party who performed substantial work on any project covered by this
Agreement or the Management Agreement (including any employees at the New Centers which are acquired by Buyer hereunder) without the other Partys prior written consent; provided that the foregoing shall not prohibit Buyer from hiring the
employees employed exclusively at the New Centers pursuant to its Purchase Option.

14.4 Obtaining Permits and
Licenses. The Seller shall be responsible for obtaining all Regulatory Approvals required by any governmental agency with respect to the construction and operation of the New Centers and the Buyer Approved Collection Centers, prior to the
purchase of any New Center. The Seller will use its reasonable efforts and act diligently to secure any consents and approvals, including the Regulatory Approvals, required to effect the transactions contemplated by this Agreement. The Buyer agrees
to cooperate and participate to affect the transfer of permits as necessary or to obtain permits that cannot be transferred.

14.6 FCPA. Seller affirms that it, and each of its owners, directors, employees and every other person working on its behalf, has not and will not, in connection with the transactions contemplated
by this Agreement or in connection with any other business transactions involving Buyer, make, offer or promise to make any payment or transfer anything of value, directly or indirectly, (i) to any governmental official or employee (including
employees of government-owned and government-controlled corporations and public international organization), (ii) to any healthcare professional or organization, (iii) to any political party, official of a political party or candidate,
(iv) to an intermediary for payment to any of the foregoing, or (v) to any other person or entity if such payment or transfer would violate the laws of the country in which made or the laws of the United States. It is the intent of the
parties that no payments or transfers of value shall be made which have the purpose or effect of public or commercial bribery, acceptance of or acquiescence in extortion, kickbacks or other unlawful or improper means of obtaining business. This
section shall not, however, prohibit normal and customary business entertainment or the giving of business mementos of nominal value.

Section 15. General.

(a) Press Releases and Public Announcements. Neither the Buyer, on the one hand, nor the Seller, on the other hand, shall, without
the approval of the other, make any press release or other public announcement concerning the transactions contemplated by this Agreement, except as and to the extent that any such Party shall be so obligated by law, in which case the other Party
shall be advised and the Parties shall use their commercially reasonable efforts to cause a mutually agreeable release or announcement to be issued; provided, however, that the foregoing shall not preclude communications or disclosures necessary to
implement the provisions of this Agreement or to comply with the accounting and disclosure obligations of the Securities and Exchange Commission or the rules of any stock exchange or Nasdaq or to enable the Buyer or Seller to obtain debt or equity
financing.

or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. The failure of any Party hereto to enforce at any time any provision
of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereto or the right of any Party thereafter to enforce each and every such provision.
