or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any agreement, credit facility, debt or other
instrument (evidencing a Company or Subsidiary debt or otherwise) or other understanding to which the Company or any Subsidiary is a party or by which any property or asset of the Company or any Subsidiary is bound or affected, or (iii) result
in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or Governmental Authority to which the Company or a Subsidiary is subject (including federal and state securities laws and
regulations), or by which any property or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate, have or reasonably be expected to
result in a Material Adverse Effect. Payments of cash on account of principal of or interest under the Note, upon any Event of Default under the Note, or as a result of liquidated damages under any Transaction Document will not require the consent
of, any payment to, or the springing of any Lien in favor of any lender to or creditor of the Company or any Subsidiary (under a credit facility, loan agreement or otherwise) and will not result in a default under any such credit facilities, loans
or other agreements. 
 (e) Filings, Consents and Approvals. Except as disclosed in Schedule 3.1(e), the Company and WHI are
not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection with the
execution, delivery and performance by the Company and WHI of the Transaction Documents, other than (i) the filing with the Commission of one or more Registration Statements in accordance with the requirements of the Registration Rights
Agreement, (ii) filings required by state securities laws, (iii) the filing of a Notice of Sale of Securities on Form D with the Commission under Regulation D of the Securities Act (iv) the filings required in accordance with

Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens. The Company has reserved from its duly authorized capital stock a number of shares of Common Stock issuable upon conversion of the Note and upon
exercise of the Warrant which number of reserved shares is not less than the Required Minimum calculated as of the date hereof. 
 (g)
Capitalization. The number of shares and type of all authorized, issued and outstanding capital stock of the Company, and all shares of Common Stock reserved for issuance under the Company’s various option and incentive plans, is
specified in Schedule 3.1(g). Except as specified in Schedule 3.1(g), no securities of the Company are entitled to preemptive or similar rights, and no Person has any right of first refusal, preemptive right, right of participation, or
any similar right to participate in the transactions contemplated by the Transaction Documents. Except as specified in Schedule 3.1(g), there are no outstanding options, warrants, scrip rights to subscribe to, calls or commitments of any
character whatsoever relating to, or securities, rights or obligations convertible into or exchangeable for, or giving any

Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or
any Subsidiary is or may become bound to issue additional shares of Common Stock, or securities or rights convertible or exchangeable into shares of Common Stock. The issue and sale of the Securities will not, immediately or with the passage of
time, obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Investor) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price
under such securities. Schedule 3.1(g) sets forth the name, address, and number of shares of Common Stock held by each shareholder of the Company holding ten percent or more of the outstanding shares of Common Stock.

were an unfavorable decision, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect. To the knowledge of the Company, neither the Company nor any Subsidiary, nor any director or officer thereof (in
his or her capacity as such), is or has been the subject of any Action involving a claim of violation of or liability under federal or state securities laws, Canadian Securities Laws, or a claim of breach of fiduciary duty, except as specifically
disclosed in the Company Reports. There has not been, and to the knowledge of the Company, there is not pending any investigation by the Commission involving the Company or any current or former director or officer of the Company (in his or her
capacity as such). The Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act or the Securities Act. 
 (k) Labor Relations. No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the
Company or any Subsidiary. 
 (l) Compliance. Neither the Company nor any Subsidiary (i) is in default under or in violation of

(ii) is in violation of any order of any court, arbitrator or governmental body, or (iii) is or has been in violation of any statute, rule or regulation of any governmental authority, including without limitation all foreign, federal,
state and local laws relating to taxes, environmental protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as could not, individually or in the aggregate, have or reasonably be
expected to result in a Material Adverse Effect. The Company is in compliance with all effective requirements of the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations thereunder, that are applicable to it, except where such
noncompliance could not have or reasonably be expected to result in a Material Adverse Effect. 
 (m) Regulatory Permits. The Company
and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, provincial, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the Company
Reports, except where the failure to possess such permits could not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect, and neither the Company nor any Subsidiary has received any notice of
proceedings relating to the revocation or modification of any such permits. 
  

 - 13 - 

 (n) Title to Assets. The Company and the Subsidiaries have good and marketable title in fee simple
to all real property owned by them that is material to their respective businesses and good and valid title in all personal property owned by them that is material to their respective businesses, in each case free and clear of all Liens, except for
Permitted Liens. Any real property and facilities held under lease by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases of which the Company and the Subsidiaries are in compliance, except as could not,
individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect. 
 (o) Matters Relating to the
Assets. 
 (i) In the Security Agreements the Company and WHI have disclosed to the Investor all locations at which the inventory and
equipment in excess of $25,000 (other than inventory and equipment in-transit) of the Company and Subsidiaries are located, and the Company’s inventory and equipment that is kept at other locations (other than inventory or equipment in transit
or in the possession of a third party for repair or service in the ordinary course of business) does not have a value in the aggregate in excess of $150,000; and 
 (ii) Other than WHI, no other Subsidiaries of the Company own any material assets. 
 (p) Intellectual
Property Rights. 
 (i) The Company and the Subsidiaries own, or have rights to use, all patents, patent applications, trademarks,
trademark applications, service marks, trade names, copyrights and other similar rights that are necessary or material for use in connection with their respective businesses as described in the Company Reports and which the failure to so have could,
individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect (collectively, the “Intellectual Property Rights”). Schedule 3.1(p) sets forth, for the Company’s owned and licensed
Intellectual Property Rights, a complete and accurate list of all United States, international and foreign patent, copyright, trademark, service mark, trade dress, and domain name registrations and current applications, indicating, where applicable,
for each applicable jurisdiction, the registration number (or application number) and date issued or filed. 
 (ii) Neither the Company or
any Subsidiary, nor to the knowledge of the Company, any employee, officer, director or consultant to the Company or its Subsidiaries, has intentionally misappropriated any patent, invention, process, method, compound, design, formula or other
proprietary or intellectual property rights of any third Person. To the knowledge of the Company, the practice of the Intellectual Property Rights, as practiced by the Company and the Subsidiaries prior to the Initial Closing, does not infringe or
otherwise violate any proprietary rights of any third Person and except as set forth in Schedule 3.1(p), the Company and the Subsidiaries have not received any written notice alleging any such infringement prior to the Initial Closing Date.
The consummation of the transactions contemplated by this Agreement and the Transaction Documents and, to the Company’s knowledge, the use by the Company and the Subsidiaries immediately after the Initial Closing of the Intellectual Property
Rights will not infringe or otherwise violate any proprietary rights of 

  

 - 14 - 

 
any third Person. To the knowledge of the Company, there are no rights owned by any third party which would prevent the development, manufacture, operation,
sale or use by the Company or any Affiliate of the Company of any Product or that would materially impede the ongoing operation of the business. The Company and the Subsidiaries have received no written notice from a third Person that threatens
legal proceedings against the Company or a Subsidiary if the Company or Subsidiary does not execute a license with such third Person, to use such third Person’s intellectual property rights that such third Person claims apply to any Product.

 (iii) The Company and the Subsidiaries have taken all reasonable steps to protect the confidentiality of all Intellectual Property
Rights, including entering into appropriate forms of confidentiality and assignment agreements with all employees and consultants having access to confidential information requiring them not to disclose such information or to use the same for their
own benefit or for the benefit of any other Person. To the knowledge of the Company, no Person is in breach of any such Confidentiality and Assignment Agreement in any respect that could adversely affect the Intellectual Property Rights or the
Company’s rights therein. 
 (q) Accounts Receivable. The Company and WHI have provided to Investor a true, correct and complete
list, including aging information, of all of the Company’s and WHI’s accounts receivable as of September 30, 2007.

not solely relating to the Company or its business). 
 (ii) No Notices. Except as set forth in Schedule 3.1(r), since
January 1, 2005, the Company has not received written notice of and, to the knowledge of the Company, is not subject to, any adverse inspection, finding of deficiency, finding of non-compliance, compelled or voluntary recall, investigation,

registrations and authorizations from, has made or will make all necessary and appropriate applications and other submissions to, and has prepared and

or material omission from, the applications, approvals, reports, or other submissions to the FDA or other Governmental Authorities or in or from any other records and documentation prepared or maintained to comply with the requirements of the FDA or
other Governmental Authorities relating to any Product, including any CE Marking certifications, 510(k)s, PMAs, IDEs, Consents from Ethics Committees, vigilance reports, line extension letters, documentation of safety and efficacy, studies or
documentation of equivalency, Product labeling, device history records, certificates of export, or MDRs.

Except as set forth in Schedule 3.1(r), since January 1, 2005, to the knowledge of the Company, no third Person, contractor, investigator, or researcher, employed or retained by the Company or otherwise acting on behalf of the Company,
has made any material false statement in, or material omission from, any report, study or other documentation prepared in conjunction with the applications, approvals, reports, or records submitted to or prepared for the FDA or other Governmental
Authorities relating to any Product, nor to the knowledge of the Company, has any such third Person, contractor, investigator or researcher failed to substantially comply with any testing requirements, study protocols or requirements to obtain any
Consent from Ethics Committees in connection with work performed on behalf of the Company or work otherwise relied upon by the Company in its submissions and documentation for the FDA or other Governmental Authorities.

payment, gratuity, or other thing of value that is prohibited by any law or regulation to personnel of any Governmental Authorities. 
 (vii) No Notification. Except as set forth in Schedule 3.1(r), since January 1, 2005, the Company has not received any written notification, which remains unresolved, from any Governmental Authorities indicating that any

 (viii) General. The Company, and the conduct and operations of its business, are in compliance in all material respects with each applicable law
(including rules and regulations thereunder) of any Governmental Authority, and the Company has not received written notice of any material violations of any of the above. 
  

 - 16 - 

 (s) Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged. Assuming the Closing occurs, the Company has no reason to believe that it will not
be able to renew its and the Subsidiaries’ existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business on terms consistent with market for the
Company’s and such Subsidiaries’ respective lines of business. 
 (t) Transactions With Affiliates and Employees. Except as
set forth in the Company Reports or disclosed in Schedule 3.1(t), none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the
Company or any Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to
or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director,
trustee or partner. 
 (u) Internal Accounting Controls. The Company and the Subsidiaries maintain a system of internal accounting
controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act rules 13a-14 and 15d-14) for the
Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the
period in which the Company’s Form 10-KSB or 10-QSB, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures in accordance with Item 307
of Regulation S-K under the Exchange Act for the Company’s most recently ended fiscal quarter or fiscal year-end (such date, the “Evaluation Date”). The Company presented in its most recently filed Form 10-KSB or Form 10-QSB
the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the Company’s internal
controls that would be required to be disclosed pursuant to Item 308(c) of Regulation S-K under the Exchange Act or, to the Company’s knowledge, in other factors that could reasonably be expected to have a Material Adverse Effect on the
Company’s internal controls.

 (v) Certain Fees. Except as specified in Schedule 3.1(v), no brokerage or finder’s
fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement. The Investor
shall have no obligation with respect to any fees or with respect to any claims (other than such fees or commissions owed by the Investor pursuant to written agreements executed by the Investor which fees or commissions shall be the sole
responsibility of the Investor) made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by this Agreement. 
 (w) Certain Registration Matters. Assuming the accuracy of the Investor’s representations and warranties set forth in
Section 3.2(b)-(e), no registration under the Securities Act is required for the offer and sale of the Note by the Company to the Investor under the Transaction Documents. The Company is eligible to register its Common Stock for resale by the
Investor under Form SB-2 promulgated under the Securities Act. Except as disclosed in Schedule 3.1(w), the Company has not granted or agreed to grant to any Person any rights (including “piggy-back” registration rights) to have any
securities of the Company registered with the Commission or any other governmental authority that have not been satisfied.

and Maintenance Requirements. Except as set forth in Schedule 3.1(x), the Company has not received written notice from any Trading Market to the effect that the Company is not in compliance with the listing or maintenance requirements
thereof that has not been resolved to the satisfaction of such Trading Market as of the date hereof. Except as set forth in Schedule 3.1(x), the Company is, and has no reason to believe that it will not in the foreseeable future continue to
be, in compliance with the listing and maintenance requirements for continued listing of the Common Stock on the Trading Markets on which the Common Stock is currently listed or quoted. The issuance and sale of the Securities under the Transaction
Documents does not contravene the rules and regulations of the Trading Markets on which the Common Stock is currently listed or quoted, and, except as set forth on Schedule 3.1(x), no approval of the shareholders of the Company thereunder is
required for the Company to issue and deliver to the Investor the Securities contemplated by the Transaction Documents.

acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s articles of incorporation (or similar charter documents) or the laws of its
jurisdiction of incorporation that is or could become applicable to the Investor as a result of the Investor and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation the
Company’s issuance of the Securities and the Investor’s ownership of the Securities. 
 (aa) No Additional Agreements.
Except as disclosed in Schedule 3.1(aa), the Company does not have any agreement or understanding with any Investor with respect to the transactions contemplated by the Transaction Documents other than as specified in the Transaction
Documents.

representations and covenants in effecting transactions in securities of the Company. All disclosure provided to the Investor regarding the Company, its business and the transactions contemplated hereby, furnished by or on behalf of the Company

necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

Compliance with ERISA. 
 (i) Each member of the ERISA Group has fulfilled its obligations under the minimum funding standards of
ERISA and the Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Code with respect to each Plan. No member of the ERISA Group has (i) sought a waiver of the
minimum funding standard under Section 412 of the Code in respect of any Plan, (ii) failed to make any required contribution or payment to any Plan or “multiemployer plan” (as such term is defined in Section 3(37) of ERISA)
or in respect of any Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement, which has resulted or could result in the imposition of a Lien or the posting of a bond or other security under ERISA or the Code or

Plans”) relating to the employees of the Company are duly registered where required by, and are in good standing in all material respects under, all applicable laws. All required employer and employee contributions and premiums under the
Benefit Plans to the date hereof have been made, the respective fund or funds established under the Benefit Plans are funded in accordance with applicable laws, and no past service funding liabilities exist thereunder. 
 (iii) No Benefit Plans have any unfunded liabilities, either on a “going concern” or “winding up” basis and determined in accordance
with all applicable laws and actuarial practices and using actuarial assumptions and methods that are reasonable in the circumstances. No event has occurred and no condition exists with respect to any Benefit Plans that has resulted or could
reasonably be expected to result in any pension plan having its registration revoked or wound up (in whole or in part) or refused for the purposes of any applicable laws or being placed under the administration of any relevant pension benefits
regulatory authority or being required to pay any taxes or penalties (in any material amounts) under any applicable laws. 
 (dd)
Taxes. All Canadian and United States federal, state, provisional, county, municipality local or foreign income tax returns and all other material tax returns (including

such returns or pursuant to any assessment received by the Company and each Subsidiary have been paid except those being disputed in good faith and for which adequate reserves have been established. The charges, accruals and reserves on the books of
the Company and each Subsidiary in respect of taxes or other governmental charges have been established in accordance with GAAP. 
 (ee)
Absence of Any Undisclosed Liabilities. Except for litigation described in the Company Reports, there are no liabilities of the Company or any Subsidiary of any kind whatsoever, whether accrued, contingent, absolute, determined, determinable
or otherwise, and there is no existing condition, situation or set of circumstances which could reasonably be expected to result in such a liability, other than (i) those liabilities provided for in the Company’s financial statements and
(ii) other undisclosed liabilities which, individually or in the aggregate, could not have, or reasonably be expected to result in, a Material Adverse Effect. 
 (ff) Secured Indebtedness. As of the Initial Closing Date the Company has no material Debt that is secured by any Lien. 
 3.2 Representations and Warranties of the Investor. The Investor represents and warrants to the Company as follows: 
 (a) Organization; Authority. The Investor is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership
power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance by the Investor of the
transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate or similar action on the part of the Investor. Each Transaction Document to which it is a party has been duly executed by the Investor, and
when delivered by the Investor in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Investor, enforceable against it in accordance with its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.

 (b) Investment Intent. The Investor is acquiring the Securities as principal for its own account for investment purposes only and
not with a view to or for distributing or reselling such Securities or any part thereof, without prejudice, however, to the Investor’s right at all times to sell or otherwise dispose of all or any part of such Securities in compliance with
applicable federal and state securities laws. Subject to the immediately preceding sentence, nothing contained herein shall be deemed a representation or warranty by the Investor to hold the Securities for any period of time. The Investor is
acquiring the Securities hereunder in the ordinary course of its business. The Investor does not have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities. 
 (c) Investor Status. At the time the Investor was offered the Securities, it was, and at the date hereof it is, and on each date on which it
exercises the Warrant or converts the Note it will be, an “accredited investor” as defined in Rule 501(a) under the Securities Act. The Investor is not a registered broker-dealer under Section 15 of the Exchange Act. 
  

 - 20 -

advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general

thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such
transferred Securities under the Securities Act. The Company agrees to use its reasonable best efforts to cooperate with the Investor to facilitate the timely preparation and delivery of certificates representing the Securities to be delivered to
the transferee. 
 (b) Certificates evidencing the Securities shall bear the following legends, until such time as they are not required
under Section 4.1(c):

ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE BORROWERS.

 The Company acknowledges and agrees that the Investor may from time to time pledge, and/or grant a security interest in some or all of the Securities pursuant to a bona fide margin agreement in connection with a bona
fide margin account and, if required under the terms of such agreement or account, the Investor may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval or consent of
the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer following default by the
Investor transferee of the pledge. No notice shall be required of such pledge. At the Investor’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in
connection with a pledge or transfer of the Securities including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend
the list of selling shareholders thereunder.

sale under Rule 144(k). The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. The Company agrees that it shall, within
three Trading Days following such time as restrictive legends would not then be required under this Section 4.1(c), issue and deliver to the Investor certificates that are free of restrictive legends representing Underlying Shares or Warrant
Shares in replacement of Underlying Shares or Warrant Shares previously issued with restrictive legends. 
 4.2 Furnishing of
Information. As long as the Investor owns the Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all documents, reports and information required to be filed by
the Company after the date hereof pursuant to the Exchange Act and Canadian Securities Laws. As long as the Investor owns Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the
Investor and make publicly available in accordance with Rule 144(c) such information as is required for the Investor to sell the Underlying Shares and Warrant Shares under Rule 144. The Company further covenants that it will take such further action
as any holder of Securities may reasonably request, all to the extent 

  

 - 24 - 

 
required from time to time to enable such Person to sell the Underlying Shares and Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144. 
 4.3 Board/Observer Rights. 
 (a) From and after the Initial Closing until such time as the Note is repaid in full or the Investor no longer owns any Securities and subject to
Section 7.5, the Investor shall have the right, but not the obligation, to designate one (1) member to the Company’s Board of Directors (the “Investor Director”). The Company shall use its reasonable best efforts to cause
the Investor Director to be elected to the Company’s Board of Directors, subject to compliance with applicable laws and the rules of the Company’s Trading Market. The Investor shall have the right to remove or replace the Investor Director
by giving notice to such Investor Director and the Company, and the Company shall use its reasonable best efforts to effect the removal or replacement of any such Investor Director. Subject to any limitations imposed by applicable law, the Investor
Director shall be entitled to the same perquisites, including stock options, reimbursement of expenses and other similar rights in connection with such person’s membership on the Board of Directors of the Company, as every other non-employee
member of the Board of Directors of the Company. 
 (b) Subject to Section 7.5, at any time that there is not an Investor Director on
the Board of Directors of the Company, the Investor shall have the right to designate one (1) observer (the “Investor Observer”) to attend all meetings of the Company’s Board of Directors and committees thereof (other than
the portion of meetings from which the Investor or the Investor Observer is excluded by virtue of being “interested” or otherwise involved in matters subject to the Board of Directors’ or the committee’s deliberations, as
determined in good faith by the Board of Directors), and to receive all information made available to all members of the Board or committees thereof (other than such information relating to the portion of meetings from which the Investor or the
Investor Observer is excluded by virtue of being “interested” or otherwise involved in matters subject to the Board of Directors’ or the committee’s deliberations, as determined in good faith by the Board of Directors or such
committee, as applicable). The Investor Observer shall have the same rights as those who customarily attend such position. 
 4.4
Distribution Rights. Subject to Section 7.5, the Company hereby grants to the Investor a right of first refusal to act as the exclusive distributor in any or all territories in which the Company proposes to sell, for all of the
Company’s current and future products, including, without limitation, the Levacor Rotary VAD (each a “New Product”), other than those products currently being sold by the Company on the date of this Agreement to the extent the Company
continues to sell them on a continuous basis following the date of this Agreement. The procedure for exercising this right of first refusal shall be as follows: 
 (a) Sufficiently in advance of the Company’s anticipated launch of a New Product (such advance timing to be determined by the Company in its sole discretion, but by way of example, promptly following the
FDA’s acceptance of a PMA submission for filing in the US in connection with a New Product), the Company shall submit a written offer (an “Offer”) to the Investor (i) stating that the Company desires to distribute a New Product
in a territory or territories, (ii) setting forth a complete technical description of the New Product to be distributed and (iii) stating the distribution terms and conditions that the Company proposes for the New Product (the
“Offered Terms”). 
  

 - 25 - 

 (b) From and after the date of any Offer, the Company shall provide to the Investor such additional data
and information about the New Product as the Investor shall reasonably request. The Investor shall have 20 Business Days from the date of the Offer, to assess the Company’s proposed distribution terms, following which the Investor shall inform
the Company whether it wishes to act as the exclusive distributor in the relevant territory or territories, of the New Product by delivery of a notice (a “Distribution Election”) to the Company. Upon receipt by the Company of a
Distribution Election, the parties agree to negotiate in good faith, the terms (including without limitation, the exclusive distribution territory or territories and the final distribution terms and conditions, which may be different than the
Offered Terms) of a definitive and binding distribution agreement, in form and substance satisfactory to both parties and their counsel. If after a period of 90 calendar days from the date of the Distribution Election, the parties are unable to
agree upon the terms of a distribution arrangement, then the Company shall have the right to: (i) distribute the New Products itself in any or all territories covered by the Offer; and/or (ii) engage another distributor or distributors, to
distribute the New Products in any or all territories covered by the Offer, in each case under clause (ii), on terms and conditions substantially similar to (and in no event more favorable than) the Offered Terms. In the event that the Company
wishes to engage another distributor or distributors on terms more favorable than the Offered Terms, the Investor shall have 20 Business Days after the date on which such more favorable terms are provided by the Company to the Investor, to exercise
its right to match such more favorable distribution terms and become the exclusive distributor for such New Product in the relevant territory or territories; provided however, that if after 30 calendar days following the date on which such more
favorable terms are provided by the Company to Investor, the parties are unable to agree upon the terms of a definitive and binding distribution agreement, then the Company shall have the right to: (i) distribute the New Products itself in any
or all of the relevant territory or territories; and/or (ii) engage another distributor or distributors, to distribute the New Products in any or all of the relevant territory or territories on such more favorable terms. 
 (c) All information provided by one of the parties to the other pursuant to this Section 4.4 (other than the terms of a definitive distribution
agreement executed by the Company and the Investor which shall be subject to the confidentiality provisions contained in such agreement), shall constitute the confidential information of such disclosing party and shall not be disclosed by the other
party to any third Person without the disclosing party’s prior written consent, which consent may be granted or withheld by the disclosing party in its sole discretion. 
 4.5 Special Shareholder Meeting. 
 (a)
Promptly after the date hereof, the Company will take all action necessary in accordance with applicable law and its articles of incorporation and bylaws to convene a special shareholder meeting to be held as promptly as practicable, and in any
event (to the extent permissible under applicable law), for the purpose of voting to authorize the issuance of the Securities to the Investor as required by Nasdaq Marketplace Rule 4350(i) and any other applicable Nasdaq Marketplace Rule
(collectively, the “Nasdaq Rules”) and the rules of the TSX (the “Shareholder Meeting”); provided, however, that if the definitive documents are 

  

 - 26 - 

 
executed in connection with the PIPE prior to February 29, 2008, the Company will only be required to hold one such Shareholder Meeting and will solicit
the approval of the issuance and sale of the Securities and the PIPE simultaneously. In such case, the Company will hold such combined Shareholder Meeting promptly but in no event later than two months after February 29, 2008. Notwithstanding
the foregoing, the Investor may, in its sole discretion, insist that the Company immediately set the record date and hold the Shareholder Meeting for the purposes of approval of the issuance of the Securities in advance of any PIPE transaction
approval in the event that the Investor has received notice pursuant to the Voting Agreements that one of the shareholders on Exhibit 2.2(a)(viii) has sold any of the Common Stock held by such shareholder. The Company will use its reasonable
best efforts to secure the vote or consent of its shareholders required by the Nasdaq Rules and the rules of the TSX. The Company may adjourn or postpone the Shareholder Meeting to the extent necessary to ensure that any necessary supplement or
amendment to the proxy statement/prospectus is provided to the Company’s shareholders in advance of a vote on the issuance of the Securities or, if as of the time for which the Shareholder Meeting is originally scheduled (as set forth in the
proxy statement/prospectus) there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Shareholder Meeting. The Company shall ensure that the
Shareholder Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by the Company in connection with the Shareholder Meeting are solicited, in compliance with applicable law, its articles of incorporation and
bylaws, the applicable rules of the Nasdaq Stock Market and the TSX and all other applicable legal requirements. 
 (b) (i) The Board of
Directors of the Company shall recommend that the Company’s shareholders vote in favor of and adopt and approve the issuance of the Securities to the Investor as required by the Nasdaq Rules and the rules of the TSX; (ii) the proxy
statement/prospectus shall include a statement to the effect that the Board of Directors of the Company has recommended that the Company’s shareholders vote in favor of and adopt and approve the issuance of the Securities to the Investor; and
(iii) neither the Board of Directors of Company nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify the recommendation of the Board of Directors of the Company that the Company’s
shareholders vote in favor of and adopt and approve the issuance of the Securities to the Investor. 
 4.6 Acknowledgment of Dilution.
The Company acknowledges that the issuance of Underlying Shares upon conversion of the Note and Warrant Shares upon exercise of the Warrant will result in dilution of the outstanding shares of Common Stock, which dilution may be substantial. The
Company further acknowledges that its obligation to honor conversions under the Note is unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim
that the Company may have against any Investor. 
 4.7 Integration. The Company and WHI shall not, and shall use their reasonable best
efforts to ensure that no Affiliate of the Company or WHI shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Note in a manner that would require the registration under the Securities Act or Canadian Securities Laws of the sale of the Note to the Investor. 
  

 - 27 - 

 4.8 Reservation of Shares. The Company shall allot, reserve and keep available out of its duly
authorized shares of Common Stock solely for the purpose of issuing upon the conversion of the Note and the exercise of the Warrant, such number of shares of Common Stock equal to or greater than the Required Minimum. Upon the conversion of the Note
or the exercise of the Warrant, the Underlying Shares or the Warrant Shares, as the case may be, shall be issued as fully paid and non-assessable shares of Common Stock. 
 4.9 Conversion and Exercise Procedures. The form of Conversion Notice included in and as defined in the Note and the form of Exercise Notice included in and as defined in the Warrant set forth the totality of
the procedures required by the Investor in order to convert the Note or exercise the Warrant, as the case may be. The Company shall honor conversions of the Note and exercises of the Warrant and shall deliver the Underlying Shares and Warrant
Shares, as the case may be, in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

describing the terms of the Transaction Documents (and including as exhibits to such Current Report on Form 8-K the material Transaction Documents (including, without limitation, this Agreement and the Registration Rights Agreement)). In addition,
the Company will make such other filings and notices in the manner and time required by the Commission, Canadian Securities Laws and each Trading Market on which the Common Stock is listed. 
 4.11 Indemnification of Investor. In addition to the indemnity provided in the Registration Rights Agreement, the Company and WHI shall, jointly
and severally, indemnify and hold the Investor and their directors, officers, shareholders, partners, employees and agents (each, an “Investor Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies,
damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation (collectively, “Losses”) that any such Investor Party may suffer or incur as a
result of or relating to any misrepresentation, breach or inaccuracy of any representation, warranty, covenant or agreement made by the Company in any Transaction Document other than any Loss resulting from Investor’s gross negligence or
willful misconduct. In addition to the indemnity contained herein, the Company and WHI shall reimburse each Investor Party for its reasonable legal and other expenses (including the cost of any investigation, preparation and travel in connection
therewith) incurred in connection therewith, as such expenses are incurred. 
 4.12 Listing of Securities. The Company agrees,
(i) if the Company applies to have the Common Stock traded on any Trading Market other than those on which it is currently listed, it will include in such application the Underlying Shares and Warrant Shares, and will take such 

  

 - 28 - 

 
other action as is necessary to cause the Underlying Shares and Warrant Shares to be listed on such other Trading Market as promptly as possible,
(ii) it will take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all material respects with the Company’s reporting, filing and other obligations under the
bylaws or rules of the Trading Market and (iii) and will take all steps necessary to ensure that the Underlying Shares (including, without limitation, shares of Common Stock issuable upon the conversion of interest under the Note) and the
Warrant Shares will be listed and posted for trading in each Trading Market. Notwithstanding the foregoing, nothing in this Agreement will require the Company to continue to list its shares of Common Stock on the TSX. 
 4.13 Issuances of New Securities. The Company agrees that, unless otherwise waived in writing by the Investor, in the event that the Company
issues any class or series of its capital stock (such as preferred stock) other than its currently outstanding Common Stock (the “New Securities”), it shall amend the Investor’s Note and/or Warrant such that the Note and/or Warrant
(i) are convertible and/or exercisable into that number of shares of the New Securities equal to the Investor’s pro rata percentage ownership of the Company (assuming the conversion or exercise in full of all the securities) such that the
Investor’s pro rata percentage ownership of the Company remains the same following such issuance and (ii) have the same rights and privileges upon conversion or exercise, as applicable. 
 4.14 Use of Proceeds. The Company and WHI will use the net proceeds from the sale of the Note hereunder for working capital purposes and not to
redeem any Common Stock or Common Stock Equivalents. 
 4.15 Payment of Cash Dividend. The Company agrees, so long as the Note is
outstanding, not to declare, pay or make any provision for any cash dividend or cash distribution with respect to the Common Stock, without first obtaining the approval of the Investor. 
 4.16 Existence; Conduct of Business. For so long as the Note or the Warrant are outstanding, the Company will, and will cause each of the
Subsidiaries to, do or cause to be done all things reasonably necessary to preserve, renew and keep in full force and effect its legal existence and the rights, licenses, permits, privileges and franchises material to the conduct of its business,
provided, that the foregoing shall not prohibit (a) any sale, lease, transfer or other disposition permitted by this Agreement, (b) any merger of (i) any domestic Subsidiary with any other domestic Subsidiary, (ii) any domestic
Subsidiary with and into the Company, or (iii) any foreign Subsidiary with any other foreign Subsidiary (provided that for each of clauses (i), (ii) and (iii), each Subsidiary is wholly owned by the Company at the time of the applicable
merger) or (c) the Reincorporation Plan. 
 4.17 Price Modification. The Company shall not reset, amend or modify any purchase
price, conversion price or exercise price in connection with any equity or equity-linked securities without the consent of the Investor, whether the issuance of such securities occurred prior to or after the date hereof: (a) prior to the record

included as part of a reincorporation of the Company into the United States, pursuant to which the Company would try to monetize certain Canadian tax losses for the benefit of the Company and its shareholders (a “Monetization Plan”). The
Company agrees not to engage in a Monetization Plan without the express written consent of the Investor, which consent shall not be unreasonably withheld so long as the Investor is satisfied, in its reasonable discretion, that such Monetization Plan

signed by the Company, WHI and the Investor. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver

 7.5 Termination. 
 (a) This Agreement
may be terminated prior to the Initial Closing: 
 (i) by written agreement of the Investor and the Company; and 
 (ii) by the Company or the Investor upon written notice to the other, if the Initial Closing shall not have taken place by 6:30 p.m. Eastern time on the

the failure of the Initial Closing to occur on or before such time. 
 (b) Failure to Fund Second Closing. If the Investor fails to
fund the remaining $4,000,000 of the Investment Amount on the Second Closing Date (or within 5 Business Days thereafter in the event of any force majeure), assuming all conditions have been met under Section 5.3, then (a) the Warrant shall

Note (including, without limitation, Section 11 of the Note), Company and WHI may elect to prepay in whole or in part the principal balance of the Note plus any accrued interest upon 5 Business Days written notice to the Investor and without
premium or penalty. Notwithstanding anything to the contrary in this Agreement or the other Transaction 

  

 - 36 - 

 
Documents, the provisions of this Section 7.5(b) shall be the exclusive remedy of WHC and WHI with respect to any failure of the Investor to fund the
remaining $4,000,000 of the Investment Amount on the Second Closing Date. 
 7.6 Construction. The headings herein are for convenience
only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and
no rules of strict construction will be applied against any party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement or any of the Transaction Documents. 
 7.7 Successors and Assigns. This Agreement
shall be binding upon, and inure to the benefit of, the parties and their legal representatives, successors and permitted assigns. Each of the Company and WHI may not assign this Agreement or any rights or obligations hereunder without the prior
written consent of the Investor; provided, however, that no consent is required in the event of an acquisition of the Company by any other Person whether by merger or through a sale of substantially all of the Company’s assets. The Investor may
assign any or all of its rights under this Agreement whether to any Person to whom the Investor assigns or transfers the Note or otherwise. 
 7.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any
other Person, except as otherwise set forth in Section 4.11. 
 7.9 Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. EACH OF THE
PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 7.10 Survival. The representations, warranties, agreements and covenants contained herein shall survive the Initial Closing and the delivery of
the Note. 
 7.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be
considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile or PDF transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or PDF
signature page were an original thereof. 
 7.12 Severability. If any provision of this Agreement is held to be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and 

  

 - 37 - 

 
provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable
provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 
 7.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation
thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The
applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities
is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 7.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Investor
will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and
hereby agree to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. 
 7.15 Payment Set Aside. To the extent that the Company makes a payment or payments to the Investor pursuant to any Transaction Document or the Investor enforces or exercises its rights thereunder, and such payment or payments or the
proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the
Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part
thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 
 7.16 Limitation of Liability. Notwithstanding anything herein to the contrary, the Company acknowledges and agrees that the liability of the
Investor arising directly or indirectly, under any Transaction Document of any and every nature whatsoever shall be satisfied solely out of the assets of the Investor, and that no trustee, officer, director, other investment vehicle or any other
Affiliate of the Investor or any investor, shareholder or holder of shares of beneficial interest of the Investor shall be personally liable for any liabilities of the Investor. 
 7.17 Reincorporation Plan. Notwithstanding anything to the contrary herein or in any of the Transaction Documents, Investor’s consent shall
not be required in connection with the Reincorporation Plan, nor shall the Transaction Documents otherwise prohibit the Reincorporation Plan.

 2. Interest. (a) The Borrowers shall
pay interest to the Investor on the aggregate unconverted and then outstanding principal amount of this Note at the rate of 8% per annum. Such interest shall accrue from the Original Issue Date of this Note, but shall not become payable until
the earlier of the Required Payment Date or the date that this Note has been paid or converted in full, at which time all interest then having accrued (including interest accrued on principal previously converted) shall become payable. Interest
payments hereunder 

  

 5 

 
may be made in cash or, subject to the conditions of Section 2(b), in shares of Common Stock. Interest shall be calculated on the basis of a 360-day
year for the actual number of days elapsed and shall accrue daily commencing on the Original Issue Date. 
 (b) Subject to the conditions
and limitations set forth below, in lieu of paying interest in cash the Company shall, at the Investor’s option, convert accrued interest on this Note by delivering on the applicable payment date, a number of shares of Common Stock equal to the
quotient obtained by dividing the amount of such interest by the average Closing Price for the ten Trading Days immediately preceding (but not including) the date Investor provides written notice of its election to convert accrued interest. The
Investor must deliver written notice to the Company indicating the manner in which it intends to receive interest at least five (5) Trading Days prior to the applicable payment date. Failure to timely provide such written notice shall be deemed
an irrevocable election by the Investor to receive such interest in cash. All interest payable in respect of this Note on the payment date must be paid in the same manner. 
 (c) Solely for purposes of the Interest Act (Canada), (i) as interest is to be computed or expressed at a rate (the “Specified
Rate”) on the basis of a year of 360 days hereunder, the annual rate of interest to which the Specified Rate is equal is the Specified Rate multiplied by a fraction, the numerator of which is the actual number of days in the relevant year
and the denominator of which is 360; (ii) the principle of deemed reinvestment of interest shall not apply to any interest calculation hereunder; and (iii) the rates of interest stipulated herein are intended to be nominal rates and not
effective rates or yields. 
 3. Registration of Transfers and Exchanges. Subject to compliance with applicable federal, state,
provincial and foreign securities laws, the Investor may transfer all or any portion of this Note and the Borrowers shall register the transfer of any portion of this Note upon surrender of this Note to the Borrowers at the address for notice set
forth herein. Upon any such registration or transfer, a new Note, in substantially the form of this Note (any such new debenture, a “New Note”), evidencing the portion of this Note so transferred shall be issued to the transferee
and a New Note evidencing the remaining portion of this Note not so transferred, if any, shall be issued to the transferring Investor. The acceptance of the New Note by the transferee thereof shall be deemed the acceptance by such transferee of all
of the rights and obligations of a holder of a Note. The Borrowers agree that their prior consent is not required for the transfer of any portion of this Note; provided, however, that the Borrowers shall be entitled to reasonable assurance
that such transfer complies with applicable federal, state and foreign securities laws. No service charge or other fee will be imposed in connection with any such registration of transfer or exchange. 
 4. Conversion. 
 (a) At the
Option of the Investor. All or any portion of the principal amount of this Note then outstanding together with any accrued and unpaid interest hereunder shall be convertible into shares of Common Stock at the Conversion Price (subject to
limitations set forth in Section 4(b)), at the option of the Investor, at any time and from time to time from and after the Original Issue Date. The Investor may effect conversions under this Section 4(a), by delivering to the Company a
Conversion Notice together with a schedule in the form of Schedule  

  

 6 

 
1 attached hereto (the “Conversion Schedule”). If the Investor is converting less than all of the principal amount and accrued and
unpaid interest represented by this Note, or if a conversion hereunder may not be effected in full due to the application of Section 4(b), the Company shall honor such conversion to the extent permissible hereunder and shall promptly deliver to
the Investor a Conversion Schedule indicating the principal amount and accrued and unpaid interest which has not been converted. 
 (b)
Certain Conversion Restrictions. Notwithstanding anything to the contrary contained herein, to the extent applicable, until such time as the issuance of shares of Common Stock under this Note and the Warrant have been approved by the
Company’s stockholders in accordance with Nasdaq Marketplace Rule 4350(i) and any applicable Nasdaq Marketplace Rule, the number of shares of Common Stock that may be acquired by the Investor upon conversion of this Note (or otherwise in
respect hereof) and upon exercise of the Warrant, together, shall be limited to no greater than 19.9% of the total number of shares of Common Stock outstanding on the Original Issue Date (the “Initial Cap”). For the avoidance of doubt, in
implementing the foregoing restriction, the Investor shall be free to exercise the Warrant for the full amount of the Initial Cap to the extent that the Investor has not converted the Note into shares of Common Stock and any cash payments made to
the Investor under this Note shall not be counted in any way towards the Initial Cap. Notwithstanding the foregoing, to the extent that the limitation set forth in this Section 4(b) prevents the issuance of shares on conversion, the Investor is
nonetheless entitled to payment of any and all principal and interest provided for hereunder in accordance with the terms of this Note. 
 5.
Mechanics of Conversion. 
 (a) The number of Underlying Shares issuable upon any conversion hereunder shall equal the outstanding
principal amount of this Note to be converted, divided by the Conversion Price on the Conversion Date, plus (if indicated in the applicable Conversion Notice) the amount of any accrued but unpaid interest on this Note through the Conversion Date,
divided by the Conversion Price on the Conversion Date. 
 (b) The Company shall, by the third Trading Day following each Conversion Date,
issue or cause to be issued and cause to be delivered to or upon the written order of the Investor and in such name or names as the Investor may designate a certificate for the Underlying Shares issuable upon such conversion. The Investor, or any
Person so designated by the Investor to receive Underlying Shares, shall be deemed to have become holder of record of such Underlying Shares as of such Conversion Date. 
 (c) The Investor shall not be required to deliver the original Note to the Company in order to effect a conversion hereunder except in connection with a conversion that brings the outstanding principal amount plus all
accrued and unpaid interest balance to zero. Execution and delivery of the Conversion Notice shall have the same effect as cancellation of this Note and issuance of a New Note representing the remaining outstanding principal amount. 
 (d) The Company’s obligations to issue and deliver Underlying Shares upon conversion of this Note in accordance with the terms hereof are absolute
and unconditional, irrespective of any action or inaction by the Investor to enforce the same, any waiver or consent 

  

 7 

 
with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim,
recoupment, limitation or termination, or any breach or alleged breach by the Investor or any other Person of any obligation to the Borrowers or any violation or alleged violation of law by the Investor or any other Person, and irrespective of any
other circumstance which might otherwise limit such obligation of the Borrowers to the Investor in connection with the issuance of such Underlying Shares. 
 (e) If by the third Trading Day after a Conversion Date the Company fails to deliver to the Investor such Underlying Shares in such amounts and in the manner required pursuant to Section 4, then the Investor will
have the right to rescind the Conversion Notice pertaining thereto by giving written notice to the Company prior to the Investor’s receipt of such Underlying Shares. 
 6. Consequences of Events of Default. 
 (a)
At any time or times following the occurrence and during the continuance of an Event of Default, the Investor may elect, by written notice to the Borrowers (an “Event Notice”), to require the Borrowers to purchase all or any portion
of the outstanding principal amount of this Note, as indicated in such Event Notice, for a purchase price in dollars in cash equal to 100% of such outstanding principal amount plus all accrued but unpaid interest thereon and other amounts then owing
to the Investor under the Loan Documents, through the date of purchase. The aggregate amount payable pursuant to the preceding sentence is referred to as the “Event Price.” The Borrowers shall jointly and severally pay the Event
Price to the Investor (free of any claim of subordination) no later than the 5th Trading Day following the date of delivery of the Event Notice, and upon receipt thereof the Investor shall deliver the original Note so repurchased to the
Borrowers. 
 (b) Upon the occurrence of any Bankruptcy Event with respect to the Company or WHI, all outstanding principal and accrued but
unpaid interest on this Note and other amounts then owing under the Loan Documents shall immediately become due and payable in full in dollars in cash (free of any claim of subordination), without any action by the Investor. 
 (c) In connection with any Event of Default, the Investor need not provide and the Borrowers hereby waive any presentment, demand, protest or other
notice of any kind (other than the Event Notice), and the Investor may immediately enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Any such declaration may be rescinded and
annulled by the Investor at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereto. 
 7. Charges, Taxes and Expenses. 
 (a) Issuance of certificates for Underlying Shares upon conversion of (or otherwise in respect of) this Note shall be made without charge to the Investor for any issue or transfer tax, withholding tax, transfer agent fee or other incidental
tax or expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Borrowers; 

  

 8 

 
provided, however, that the Borrowers shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of
any certificates for Underlying Shares or Notes in a name other than that of the Investor. 
 (b) Except as provided in Section 7(c),
any and all payments by either Borrower to or for the account of the Investor under any Transaction Document shall be made free and clear of and without deduction for any and all present or future taxes, duties, levies, imposts, deductions,
assessments, fees, withholdings or similar charges, and all liabilities (including additions to tax, penalties and interest) with respect thereto, excluding taxes imposed on or measured by the Investor’s net income, and franchise (and similar)
taxes imposed on it in lieu of net income taxes, by the jurisdiction (or any political subdivision thereof) under the laws of which the Investor is organized, and all liabilities (including additions to tax, penalties and interest) with respect
thereto (all such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and liabilities being hereinafter collectively referred to as “Taxes”). 
 (c) If either Borrower shall be required by any laws to deduct any Taxes from or in respect of any sum payable under any Transaction Document to the
Investor, (i) the sum payable shall be increased as necessary so that, after making all required deductions, the Investor receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall
make such deductions, (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable laws, and (iv) within thirty (30) days after the date of such payment
(or, if receipts or evidence are not available within thirty (30) days, as soon as possible thereafter), such Borrower shall furnish to the Investor the original or a facsimile copy of a receipt evidencing payment thereof to the extent such a
receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Investor. If either Borrower fails to pay any Taxes when due to the appropriate taxing authority or fail to remit to the Investor the
required receipts or other required documentary evidence, the Borrowers shall jointly and severally indemnify the Investor for any incremental taxes, interest or penalties that may become payable by the Investor arising out of such failure.

 8. Reservation of Underlying Shares. The Company covenants that it will at all times reserve and keep available out of the
aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Underlying Shares as required hereunder, the number of Underlying Shares which are then issuable and deliverable upon the
conversion of (and otherwise in respect of) this entire Note (taking into account the adjustments of Section 9 and interest thereon), free from preemptive rights or any other contingent purchase rights of persons other than the Investor. The
Company covenants that all Underlying Shares so issuable and deliverable shall, upon issuance in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and non-assessable. 
 9. Certain Adjustments. The Conversion Price is subject to adjustment from time to time as set forth in this Section 9. 
 (a) Stock Dividends and Splits. If the Company, at any time while this Note is outstanding: (i) pays a stock dividend on its Common Stock or
otherwise makes a 

  

 9 

 
distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger
number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Initial Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares
of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall
become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective
immediately after the effective date of such subdivision or combination. 
 (b) Pro Rata Distributions. If the Company, at any time
while this Note is outstanding, distributes to all holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants
to subscribe for or purchase any security, or (iv) any other asset (in each case, “Distributed Property”), then, at the request of the Investor delivered before the 90th day after the later of the record date fixed for
determination of shareholders entitled to receive such distribution and the date the Company gives the Investor notice of such record date, the Company will deliver to the Investor, within five Trading Days after such request (or, if later, on the
effective date of such distribution), the Distributed Property that the Investor would have been entitled to receive in respect of the Underlying Shares for which this Note could have been converted immediately prior to such record date. If such
Distributed Property is not delivered to the Investor pursuant to the preceding sentence, then upon any conversion of this Note that occurs after such record date, the Investor shall be entitled to receive, in addition to the Underlying Shares
otherwise issuable upon such conversion, the Distributed Property that the Investor would have been entitled to receive in respect of such number of Underlying Shares had the Investor been the record holder of such Underlying Shares immediately
prior to such record date. Notwithstanding the foregoing, this Section 9(b) shall not apply to any distribution of rights or securities in respect of adoption by the Company of a shareholder rights plan, which events shall be covered by
Section 9(a). 
 (c) Fundamental Transactions. If, at any time while this Note is outstanding, (i) the Company effects any
amalgamation, merger or consolidation of the Company with or into another Person in which the Company is not the surviving entity or the Company’s shareholders own less than fifty percent (50%) of the outstanding voting share of the
resulting person in which the Company is not the surviving entity , (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any take-over bid, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock tender or exchange their shares for other securities, cash or property, or (iv) the Company effects any reclassification of the Common Stock
or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by
Section 9(a) above) (in any such case, a “Fundamental Transaction”), then upon any subsequent conversion of this Note, the Investor shall have the right to (x) receive, for each Underlying Share that would have been
issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such 

  

 10 

 
Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the “Alternate
Consideration”) or (y) require the surviving entity to issue to the Investor an instrument identical to this Note (with appropriate adjustments to the conversion price and equity terms so that the Investor has the same economic
rights). Notwithstanding anything to the contrary in any of the Transaction Documents, neither the Reincorporation Plan, nor a Monetization Plan approved by the Investor pursuant to the Purchase Agreement, shall be a “Fundamental
Transaction”. For purposes of any such conversion, the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate
Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Investor shall be given the same choice as to the Alternate Consideration it receives upon
any conversion of this Note following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction (or, if different, the ultimate
parent of such successor or entity or the entity issuing the Alternate Consideration) shall issue to the Investor a new note consistent with the foregoing provisions and evidencing the Investor’s right to convert such note into Alternate
Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that this
Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. 
 (d) Subsequent Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Note is outstanding, shall issue shares of Common Stock or Common Stock Equivalents entitling any Person to acquire shares
of Common Stock (an “Adjustment Event”), at a price per share less than the Initial Conversion Price as in effect immediately prior to the Adjustment Event (if the holder of the Common Stock or Common Stock Equivalent so issued may,
whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, become entitled to receive shares of Common Stock at a price less than the Initial Conversion Price, but such price
is not fixed at the time of issuance, such issuance shall be deemed to occur (i) in the case of purchase price adjustments and reset provisions, at the time, if any, that such adjustment or reset occurs, or (ii) in the case of conversion,
exercise or exchange prices, the date of such conversion, exercise or exchange) (the “Adjustment Shares”), then, the “Adjusted Conversion Price” shall be determined as follows: 
  

											
	A	  	=	  	I*	  	 CS
	  	 	  	 
		  		  		  	CS + (0.2485*AS)(P/5,000,000)	  		  	

  

							
				
	Where:	  		  		  	
			
	A	  	=	  	Adjusted Conversion Price.
			
	AS	  	=	  	Number of Adjustment Shares issued at any time after the Original Issue Date up to and including the Adjustment Shares issued in the Adjustment Event.
			
	I	  	=	  	Initial Conversion Price, as in effect immediately prior to the Adjustment Event.
			
	P	  	=	  	The principal amount of this Note outstanding immediately prior to the Adjustment Event.
			
	CS	  	=	  	Shares issuable upon conversion of the principal amount of this Note outstanding immediately prior to the Adjustment Event based on the Initial Conversion Price in effect
immediately prior to the Adjustment Event.

  

 11 

 Notwithstanding anything to the contrary set forth herein, the Adjusted Conversion Price shall never be increased as a
result of the issuance of Adjustment Shares. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued; provided, however, that no adjustment shall be made pursuant to this Section 9(d) as a result
of (i) the exercise of the Warrant or the conversion, in whole or in part, of this Note, (ii) the grant of equity incentive awards issued to employees, officers, directors or consultants, representing no more than an aggregate of 1,000,000
shares of Common Stock and issued at no less than $0.80 and no more than the Initial Conversion Price, pursuant to any benefits plan approved by the Board of Directors of the Company (for the avoidance of doubt, no such equity grants issued above
the Initial Conversion Price shall result in any adjustment pursuant to the terms hereof) and (iii) the exercise of any such equity incentive awards outstanding under the Company’s benefit plans on the date hereof. The Company shall notify
the Investor in writing, no later than the Trading Day following the issuance of any Common Stock or Common Stock Equivalent subject to this Section 9, indicating therein the applicable issuance price, or applicable reset price, exchange price,
conversion price and other pricing terms. At any time that the Initial Conversion Price is adjusted under this Note, whether pursuant to Section 9(a) or otherwise, the Adjusted Conversion Price shall be recalculated using the Initial Conversion
Price as so adjusted that is then in effect. This Section 9(d) is used solely to calculate the Adjusted Conversion Price as of any given time and does not modify the Initial Conversion Price. 
 (e) Reclassifications; Share Exchanges. In case of any reclassification of the Common Stock, or any compulsory share exchange pursuant to which
the Common Stock is converted into other securities, cash or property (other than compulsory share exchanges which constitute Change of Control transactions), the Investor shall have the right thereafter to convert such shares only into the shares
of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Stock following such reclassification or share exchange, and the Investor shall be entitled upon such event to receive such amount of
securities, cash or property as a holder of the number of shares of Common Stock of the Company into which this Note could have been converted immediately prior to such reclassification or share exchange would have been entitled. This provision
shall similarly apply to successive reclassifications or share exchanges. 
 (f) Calculations. All calculations under this
Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and
the disposition of any such shares shall be considered an issue or sale of Common Stock. 
 (g) Notice of Adjustments. Upon the
occurrence of each adjustment pursuant to this Section 9, the Company at its expense will promptly compute such adjustment in accordance with the terms hereof and prepare a certificate describing in reasonable detail such adjustment and the
transactions giving rise thereto, including all facts upon which such adjustment is based, and promptly deliver a copy of each such certificate to the Investor. 
  

 12 

 (h) Notice of Corporate Events. If the Company (i) declares a dividend or any other
distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any Subsidiary, (ii) authorizes
and publicly approves, or enters into any agreement contemplating or solicits shareholder approval for any Change of Control or (iii) publicly authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then
the Company shall deliver to the Investor a notice describing the material terms and conditions of such transaction, at least 20 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in
order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to insure that the Investor is given the practical opportunity to convert this Note prior to such time so as to
participate in or vote with respect to such transaction. 
 10. Fractional Shares. The Company shall not be required to issue or cause
to be issued fractional Underlying Shares on conversion of this Note. If any fraction of an Underlying Share would, except for the provisions of this Section, be issuable upon conversion of this Note or payment of interest hereon, the number of
Underlying Shares to be issued will be rounded down to the nearest whole share and Investor shall receive a cash payment in-lieu of such fractional share based on the average Closing Price for the ten Trading Days immediately preceding any
applicable Conversion Notice. 
 11. Payment at Option of Borrowers. Subject to
the provisions of this Section and upon at least thirty (30) days’ notice prior to any planned Payment Date, the Borrowers may deliver a written notice (such notice, a “Payment Notice”) to the Investor stating their
irrevocable undertaking to prepay, at any time on or after the Maturity Date, all or part of the outstanding principal amount of this Note, together with accrued and unpaid interest on such outstanding principal amount and other amounts then owing
(other than interest and principal) under the Transaction Documents, provided however, that the Equity Conditions Are Satisfied as to all Underlying Shares, and provided further, that if an Event of Default exists at such time, the
Borrowers shall pay the Investor an additional amount equal to 5% of the outstanding principal amount being paid. If the conditions for delivery of a Payment Notice set forth above are satisfied during the period from the date of the Payment Notice
through and including the Payment Date, then the Borrowers shall deliver to the Investor the full applicable payment amount in cash on the 31st day following the date of the Payment Notice (such date, the “Payment Date”),
subject to (i) reduction for principal and interest of this Note that shall have been converted between the date of the Payment Notice and the Payment Date and (ii) the right of the Investor to nullify such Payment Notice if any of such
conditions shall not have been met from the date of the Payment Notice through the Payment Date or if the Borrowers shall during such period fail to honor any Conversion Notice as contemplated in the immediately following sentence. The Company
covenants and agrees that it will honor all Conversion Notices tendered from the time of delivery of the Payment Notice through 6:00 p.m. (Boston time) on the Trading Day prior to the Payment Date. In addition, if any portion of the amount to be
paid pursuant to the Payment Notice remains unpaid after the Payment Date, the Investor may elect by written 

  

 13 

 
notice to the Borrowers to invalidate ab initio the Payment Notice with respect to the unpaid amount, notwithstanding anything herein contained to the
contrary. If the Investor makes such an election, Investor shall return such payment to Borrowers, this Note shall be reinstated with respect to such unpaid amount and the Borrowers shall no longer have any payment rights under this Section.
Notwithstanding anything to the contrary herein, Company and WHI may elect to prepay the Note as set forth in Section 7.5(b) of the Purchase Agreement. This Section 11 shall not apply to Company’s and WHI’s obligations to pay on
the Required Payment Date (for the avoidance of doubt, other than on the Payment Date). 
 12. Notices. Any and all notices or other
communications or deliveries hereunder (including without limitation any Conversion Notice) to or upon Abiomed, WHC or WHI hereunder shall be effected in the manner provided for in Section 7.3 of the Purchase Agreement. 
 13. Miscellaneous. 
 (a) This Note
shall be binding on and inure to the benefit of the parties hereto and their successors and assigns. 
 (b) Subject to Section 13(a),
above, nothing in this Note shall be construed to give to any person or corporation other than the Borrowers and the Investor any legal or equitable right, remedy or cause under this Note. This Note shall inure to the sole and exclusive benefit of
the Borrowers and the Investor. 
 (c) All questions concerning the construction, validity, enforcement and interpretation of this Note
shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. THE PARTIES HERETO WAIVE ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY
LITIGATION WITH RESPECT TO THIS NOTE AND EACH REPRESENT THAT ITS COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 (d) The
headings herein are for convenience only, do not constitute a part of this Note and shall not be deemed to limit or affect any of the provisions hereof. 
 (e) In case any one or more of the provisions of this Note shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Note shall not in any way be
affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision which shall be a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision
in this Note. 
 (f) No provision of this Note may be waived or amended except (i) in accordance with the requirements set forth in the
Purchase Agreement, and (ii) in a written instrument signed, in the case of an amendment, by the Company, WHI and the Investor or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any
default with respect to any provision, condition or requirement of this Note shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a 

  

 14 

 
waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner
impair the exercise of any such right. 
 (g) To the extent it may lawfully do so, the Borrowers hereby agree not to insist upon or plead or
in any manner whatsoever claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at any time hereafter in force, in connection with any claim, action or Proceeding that may
be brought by the Investor in order to enforce any right or remedy under this Note. Notwithstanding any provision to the contrary contained in this Note, it is expressly agreed and provided that the total liability of the Borrowers under this Note
for payments in the nature of interest shall not exceed the Maximum Rate, and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest
that the Borrowers may be obligated to pay under this Note exceed such Maximum Rate. It is agreed that if the maximum contract rate of interest allowed by law and applicable to this Note is increased or decreased by statute or any official
governmental action subsequent to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate of interest applicable to this Note from the effective date forward, unless such application is precluded by
applicable law. Except as provided in Section 13(h) below, if under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Borrowers to the Investor with respect to indebtedness evidenced by this Note, such excess
shall be applied by the Investor to the unpaid principal balance of any such indebtedness or be refunded to the Borrowers, the manner of handling such excess to be at the Investor’s election. 
 (h) Without limiting Section 13(g), in no event shall the aggregate “interest” (as defined in Section 347 (the “Criminal
Code Section”) of the Criminal Code (Canada)), payable to the Investor by the Company under this Note or any other Transaction Document exceed the effective annual rate of interest lawfully permitted under the Criminal Code Section on the
“credit advanced” (as defined in such section) under this Note or any other Transaction Document. Further, if any payment, collection or demand pursuant to this Note or any other Transaction Document in respect of such “interest”
is determined to be contrary to the provisions of the Criminal Code Section, such payment, collection, or demand shall be deemed to have been made by mutual mistake of the Investor and the Company and such “interest” shall be deemed to
have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by the Criminal Code Section so as to result in a receipt by the Investor of interest at a rate not in
contravention of the Criminal Code Section, such adjustment to be effected, to the extent necessary, as follows: 
  

	 	(1)	first, by reducing the amounts or rates of interest required to be paid to the Investor; and 

  

	 	(2)	then, by reducing any fees, charges, expenses and other amounts required to be paid to the Investor that would constitute “interest”. 

 Notwithstanding the above, and after giving effect to all such adjustments, if the Investor shall have received an amount in excess of the maximum
permitted by the Criminal Code Section, then the Company shall be entitled, by notice in writing to the Investor, to obtain reimbursement from the Investor in an amount equal to such excess. 
 (i) The obligations under this Note are secured pursuant to the Security Agreements. 
  

 15 

 IN WITNESS WHEREOF, the Company and WHI have caused this Note to be duly executed by their duly
authorized officers as of the date first above indicated.
