Exhibit 10.2

SUPPORT AGREEMENT

     This SUPPORT AGREEMENT (the “Agreement”), dated as of February 12, 2009, is entered
into by and between the undersigned stockholder (“Stockholder”) of HeartWare International,
Inc., a Delaware corporation (the “Company”), and Thoratec Corporation, a California
corporation (“Parent”).

     WHEREAS, concurrently with the execution of this Agreement, the Company, Parent, Thomas Merger
Sub I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger
Subsidiary”) and Thomas Merger Sub II, Inc., a Delaware corporation and a wholly-owned
subsidiary of Parent (“Merger Subsidiary Two”), are entering into an Agreement and Plan of
Merger (as the same may be amended from time to time, the “Merger Agreement”), providing
for the merger of Merger Subsidiary with and into the Company (the “Merger”), with the
Company continuing as the surviving corporation (the “Intermediate Surviving Corporation”)
and the merger of the Intermediate Surviving Corporation with and into Merger Subsidiary Two, with
Merger Subsidiary Two as the surviving corporation (the “Second Merger” and together with
the Merger, the “Mergers”) pursuant to the terms and subject to the conditions set forth in
the Merger Agreement;

     WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Parent has
requested that Stockholder make certain representations, warranties, covenants and agreements with
respect to the shares of common stock, par value $0.001 per share, of the Company (the “Common
Stock”) and/or CHESS Depositary Interests representing shares of Common Stock (collectively,
with the Common Stock, the “Shares”) beneficially owned by Stockholder and set forth
opposite Stockholder’s name on Schedule A attached hereto (the “Stockholder
Shares”); and

     WHEREAS, in order to induce Parent to enter into the Merger Agreement, Stockholder is willing
to make certain representations, warranties, covenants and agreements with respect to the
Stockholder Shares as set forth herein;

     NOW, THEREFORE, in consideration of the promises contained herein and for other good and
valuable consideration, the receipt, sufficiency and adequacy of which is hereby acknowledged, the
parties hereto agree as follows:

          1. Representations of Stockholder. Stockholder represents and warrants to Parent that
(a) Stockholder beneficially owns all of the Stockholder Shares free and clear of any lien,
encumbrance or restriction and, except pursuant to this Agreement, there are no rights, agreements
or commitments to which Stockholder is a party relating to the pledge, disposition or voting of any
Shares, and there are no voting trusts or voting agreements with respect to the Stockholder Shares,
(b) Stockholder does not beneficially own any Shares other than the Stockholder Shares and (c)
Stockholder has full power and authority to enter into, execute and deliver this Agreement and to
perform fully Stockholder’s obligations hereunder, and no permit, authorization, consent or
approval from any Person is necessary therefor. Stockholder further represents and warrants to
Parent that this Agreement has been duly executed and delivered by

 

 

Stockholder and constitutes the legal, valid and binding obligation of Stockholder enforceable
against Stockholder in accordance with its terms.

          2. Representations of Parent. Parent represents and warrants to Stockholder that (a)
Parent has full power and authority to enter into, execute and deliver this Agreement and to
perform fully Parent’s obligations hereunder and no permit, authorization, consent or approval from
any Person is necessary therefore and (b) this Agreement has been duly executed and delivered by
Parent and constitutes the legal, valid and binding obligation of Parent enforceable against Parent
in accordance with its terms.

          3. Agreement to Vote Shares. From the date of this Agreement to the earliest to occur
of (a) the date upon which the Merger Agreement is validly terminated, (b) the Effective Time of
the Merger, (c) the date following receipt of the Company Stockholder Approval, (d) the date that
any material amendment shall be made to the Merger Agreement (a “material amendment” shall mean any
valid written amendment to the Merger Agreement reducing the consideration payable to Stockholder
pursuant to the Merger Agreement and any other valid written amendment to the Merger Agreement that
would materially delay the consummation of the Merger) without the written consent of Stockholder
and (e)(i) any amendment to the Articles of Incorporation or Bylaws (whether by merger,
consolidation or otherwise) of Parent in any manner that would have a disparate effect on holders
of Shares, as holders of Parent Stock at and following the Effective Time, relative to other
holders of Parent Stock, and (ii) any amendment to the Articles of Incorporation of Parent to
provide for any class of capital stock with rights to distributions or upon a liquidation
(including upon a merger, consolidation, asset sale or similar transaction) that are superior to
those of the Parent Stock, other than an amendment in connection with a shareholder rights plan,
“poison pill” anti-takeover plan or other similar device (the earliest of such to occur being the
“Voting Covenant Expiration Date”), Stockholder shall, and shall cause any holder of record
of the Stockholder Shares or any New Shares (as defined in Section 9 hereof) to vote, or
cause to be voted, the Stockholder Shares and any New Shares (i) in favor of (A) adoption of the
Merger Agreement, (B) any other action in furtherance thereof; provided, that such action does not
require a material amendment to the Merger Agreement to which Stockholder has not consented, and
(C) any adjournment or postponement recommended by the Company with respect to any stockholder
meeting concerning the Merger Agreement and the Mergers and (ii) against any Acquisition Proposal
and any action or agreement that would result in a breach of any representation, warranty, covenant
or obligation of the Company in the Merger Agreement or impair the ability of the Company to
consummate the Merger. In addition, Stockholder agrees not to take, or commit or agree to take,
any action inconsistent with the foregoing.

          4. No Voting Trusts or Other Arrangements. Except as otherwise set forth herein,
Stockholder agrees that Stockholder will not, and will not permit any entity under Stockholder’s
control to, deposit any of the Stockholder Shares or any New Shares in a voting trust, grant any
proxies or power of attorney with respect to the Stockholder Shares or any New Shares or subject
any of the Stockholder Shares or any New Shares to any arrangement with respect to the voting of
the Stockholder Shares or any New Shares other than agreements entered into with Parent.

2

 

          5. No Solicitations. Stockholder agrees that Stockholder will not, and will not
permit any entity under Stockholder’s control or any of its or their respective officers,
directors, employees, agents or other representatives to, (a) solicit proxies or become a
“participant” in a “solicitation”, as such terms are defined in Regulation 14A under the Securities
and Exchange Act of 1934, as amended (the “Exchange Act”), in opposition to or competition
with the consummation of the Mergers or otherwise encourage or assist any party in taking or
planning any action which would reasonably be expected to compete with, impede, interfere with or
attempt to discourage the consummation of the Mergers or inhibit the timely consummation of the
Mergers in accordance with the terms of the Merger Agreement, (b) directly or indirectly encourage,
initiate or cooperate in a stockholders’ vote or action by consent of the Company’s stockholders in
opposition to or in competition with the consummation of the Mergers, (c) become a member of a
“group” (as such term is used in Rule 13d-5 under the Exchange Act) with respect to any voting
securities of the Company for the purpose of opposing or competing with the consummation of the
Mergers or (d) unless required by applicable law, make any press release, public announcement or
other non-confidential communication with respect to the business or affairs of the Company or
Parent, including this Agreement and the Merger Agreement and the transactions contemplated hereby
and thereby, without the prior written consent of Parent.

          6. Waiver of Appraisal and Dissenters’ Rights and Actions. Stockholder hereby (a)
waives and agrees not to exercise any rights of appraisal or rights to dissent from the Mergers
that Stockholder may have and (b) agrees not to commence or participate in, and to take all actions
necessary to opt out of any class in any class action with respect to, any claim, derivative or
otherwise, against Parent, Merger Subsidiary, Merger Subsidiary Two, the Company or any of their
respective successors relating to the negotiation, execution or delivery of this Agreement or the
Merger Agreement or the consummation of the Mergers, including any claim (i) challenging the
validity of or seeking to enjoin the operation of any provision of this Agreement or (ii) alleging
a breach of any fiduciary duty of the Board of Directors of the Company in connection with the
Merger Agreement or the transactions contemplated thereby.

          7. Stockholder Capacity. Notwithstanding anything to the contrary set forth herein,
Stockholder is entering into this Agreement solely in Stockholder’s capacity as the beneficial
owner of the Stockholder Shares and New Shares, as applicable, and nothing in this Agreement shall
prevent Stockholder from taking any action or omitting to take any action in Stockholder’s capacity
as a member of the Board of Directors of the Company or any of its subsidiaries (or any committee
thereof) or as an officer or employee of the Company or any of its subsidiaries, in either case as
applicable or as may become applicable to Stockholder. If Stockholder is an officer of director of
the Company, any action taken by Stockholder in Stockholder’s capacity as an officer or director of
the Company (but, for the avoidance of doubt, excluding any action taken by Stockholder in
Stockholder’s capacity as a holder or beneficial owner of any Shares) will not be deemed to
constitute a breach of this Agreement, regardless of the circumstances related thereto.

          8. Transfer and Encumbrance. During the period from the date hereof through the
Voting Covenant Expiration Date, except as otherwise expressly contemplated by this Section
8, Stockholder agrees not to transfer, sell, offer, exchange, pledge or otherwise dispose of or
encumber any of the Stockholder Shares or New Shares and not to enter into any

3

 

contract, agreement or arrangement with respect to any of the foregoing, and any such transfer
shall be null and void and of no effect. This Section 8 shall not prohibit a transfer of
any Stockholder Shares or New Shares by Stockholder to any transferee; provided,
however, that a transfer referred to in this sentence shall be permitted only if, as a
precondition to such transfer, the proposed transferee agrees in writing, reasonably satisfactory
in form and substance to Parent, to be bound by the terms of this Agreement with respect to all of
the Stockholder Shares or New Shares so transferred; provided, further,
however, that such transfer shall not be permitted unless (a) following such transfer of
the Stockholder Shares or New Shares the proposed transferee would beneficially own, in the
aggregate, less than five percent (5%) of the outstanding Shares and (b) the transferee agrees to
limit its beneficial ownership to no more than five percent (5%) of the outstanding Shares through
the Voting Covenant Expiration Date.

          9. Additional Purchases. Stockholder agrees that (a) all Shares that Stockholder
purchases, acquires the right to vote or share in the voting of, or otherwise acquires beneficial
ownership of, including upon the exercise of options to purchase Shares, after the execution of
this Agreement and (b) all Shares which Stockholder owns beneficially or of record but has not
included as Stockholder Shares as of the date hereof for any reason (all such Shares collectively,
“New Shares”), shall be subject to the terms of this Agreement to the same extent as if
they constituted Stockholder Shares as of the date hereof.

          10. No Other Support Agreements. Except as provided in Section 8 hereof or in a
similar agreement with a director or executive officer of the Company, Parent agrees that it shall
not enter into any agreement or arrangement with any Company Stockholder pursuant to which such
Company Stockholder would agree to vote shares of Company Stock held by it in favor of the merger
other than this Agreement and similar agreements with directors and executive officers of the
Company.

          11. Specific Performance. Each party hereto acknowledges that it will be impossible
to measure in money the damage to the other party if a party hereto fails to comply with any of the
obligations imposed by this Agreement, that every such obligation is material and that, in the
event of any such failure, the other party will not have an adequate remedy at law or damages.
Accordingly, each party hereto agrees that injunctive relief or other equitable remedy, in addition
to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose
the granting of such relief on the basis that the other party has an adequate remedy at law. Each
party hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or
posting of a bond in connection with any other party’s seeking or obtaining such equitable relief.

          12. Remedies. All rights, powers and remedies provided under this Agreement or
otherwise available in respect hereof at law or in equity shall be cumulative and not alternative,
and the exercise of any such right, power or remedy by any party hereto shall not preclude the
simultaneous or later exercise of any other such right, power or remedy by such party.

          13. Entire Agreement. This Agreement and the Letter Agreement, dated February 12,
2009, between Stockholder and Parent supersede all prior agreements, written or

4

 

oral, among the parties hereto with respect to the subject matter hereof and contains the
entire agreement among the parties with respect to the subject matter hereof.

          14. Notices. All notices hereunder shall be in writing and shall be deemed given when
delivered personally, upon receipt of a transmission confirmation if sent by telecopy, electronic
mail or like transmission or on the next business day when sent by Federal Express, Express Mail or

          (a) THIS AGREEMENT, AND ALL CLAIMS AND CAUSES OF ACTION ARISING OUT OF, BASED UPON, OR RELATED
TO THIS AGREEMENT OR THE NEGOTIATION, EXECUTION OR PERFORMANCE HEREOF, SHALL BE DEEMED TO BE MADE
IN AND IN ALL RESPECTS SHALL BE GOVERNED BY, AND CONSTRUED, INTERPRETED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO CHOICE OR CONFLICT OF LAW PRINCIPLES
THAT WOULD RESULT IN THE APPLICATION OF ANY LAWS OTHER THAN THE LAWS OF THE STATE OF DELAWARE. Any

transactions contemplated hereby shall be brought solely in the Chancery Court of the State of
Delaware and any state appellate court therefrom within the State of Delaware (or, if the Chancery
Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state
or federal court within the State of Delaware and any direct appellate court therefrom). Each
party hereby irrevocably submits to the exclusive jurisdiction of such courts in respect of

5

 

any legal action, suit or proceeding arising out of, based upon or relating to this Agreement
and the rights and obligations arising hereunder and agrees that it will not bring any action
arising out of, based upon or related to this Agreement in any other court. Each party hereby
irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any legal
action, suit or proceeding arising out of, based upon or relating to this Agreement, (i) any claim
that it is not personally subject to the jurisdiction of the above named courts for any reason
other than the failure to serve process in accordance with Section 14, (ii) any claim that
it or its property is exempt or immune from jurisdiction of any such court or from any legal
process commenced in such courts (whether through service of notice, attachment prior to judgment,
attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the
fullest extent permitted by Applicable Law, any claim that (A) the suit, action or proceeding in
such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is
improper, or (C) this Agreement, or the subject mater hereof, may not be enforced in or by such
courts. Each party agrees that notice or the service of process in any action, suit or proceeding
arising out of, based upon or relating to this Agreement or the rights and obligations arising
hereunder shall be properly served or delivered if delivered in the manner contemplated by
Section 14.

          (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS
AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY
HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN
RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR
THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii)
EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES
THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN SECTION 15(a) AND THIS SECTION
15(b).

          16. Severability. If any provision of this Agreement or the application of such
provision to any person or circumstances shall be held invalid or unenforceable by a court of
competent jurisdiction, such provision or application shall be unenforceable only to the extent of
such invalidity or unenforceability, and the remainder of the provision held invalid or
unenforceable and the application of such provision to persons or circumstances, other than the
party as to which it is held invalid, and the remainder of this Agreement shall not be affected.

          17. Counterparts. This Agreement may be executed in one or more counterparts
(including by facsimile), each of which shall be deemed to be an original but all of which together
shall constitute one and the same instrument.

          18. Termination. This Agreement shall terminate automatically on the Voting Covenant
Expiration Date.

6

 

          19. Further Actions. Each party hereto shall execute and deliver such additional
documents, and use its commercially reasonable efforts to take or cause to be taken such additional
lawful actions, as may be necessary or desirable to effect the transactions contemplated by this
Agreement.

          20. “Beneficial Ownership”. For purposes of this Agreement, “beneficial
ownership” (and related terms such as “beneficially own” or “beneficial owner”) has the meaning
set forth in Rule 13d-3 under the Exchange Act.

          21. Waivers and Amendments. This Agreement may be amended, modified, altered or
supplemented only by a written instrument executed by all of the parties to this Agreement. Any
failure of the parties to this Agreement to comply with any obligation, covenant, agreement or
condition in this Agreement may be waived by the party entitled to the benefits thereof only by a
written instrument signed by the party granting such waiver. No delay on the part of any party to
this Agreement in exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party to this Agreement of any right, power or
privilege hereunder operate as a waiver of any other right, power or privilege hereunder, nor shall
any single or partial exercise of any right, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege hereunder.

          22. Merger Agreement Provisions. Capitalized terms used but not defined herein have
the respective meanings ascribed to them in the Merger Agreement. The provisions of Section 1.02
of the Merger Agreement are incorporated herein and are deemed applicable to the interpretation of
this Agreement. Stockholder acknowledges receipt of a copy of the Merger Agreement prior to the
execution of this Agreement.

          23. Effectiveness. The obligations of the parties set forth in this Agreement shall
not be effective or binding upon either party hereto until such time as the Merger Agreement is
executed and delivered by the Company, Parent, Merger Subsidiary and Merger Subsidiary Two.

          24. Certain Disclosures. Stockholder hereby authorizes Parent and the Company to
publish and disclose Stockholder’s identity and ownership of Stockholder Shares and New Shares and
the nature of Stockholder’s commitments, arrangements and understandings pursuant to this Agreement
and any other information that Parent reasonably determines to be necessary or desirable in any
press release or any other disclosure document in connection with the Mergers or any other
transactions contemplated by the Merger Agreement (including in any proxy statement or prospectus
relating to the Merger Agreement and the Mergers and in the registration statement relating to the
shares of common stock of Parent to be received by holders of Shares in the Merger and documents
and schedules filed with the Securities and Exchange Commission or the Australian Securities and
Investments Commission relating thereto or in connection therewith); provided, however, that
neither Parent nor the Company shall publish or disclose the identity of any of the partners of
Stockholder unless such disclosure is necessary to comply with a comment or request made by the
Securities and Exchange Commission, the Australian Securities and Investments Commission or a
similar regulatory body or stock exchange, and provided that, prior to making any such disclosure,
Parent or the Company has

7

 

provided the Stockholder with at least three business days prior notice thereof and has
consulted with the Stockholder concerning such disclosure. 

          25. Assignment. No party to this Agreement may assign any of its rights or
obligations under this Agreement without the prior written consent of the other party hereto,
except that Parent may assign its rights and obligations hereunder to any of its direct or indirect
wholly-owned subsidiaries (including Merger Subsidiary and Merger Subsidiary Two). Any assignment
contrary to the provisions of this Section 25 shall be null and void.

          26. Attachment to Shares. Without limiting any other rights Parent may have
hereunder, pursuant to Section 8 or otherwise, Stockholder agrees that this Agreement and
the obligations hereunder shall attach to the Stockholder Shares and any New Shares beneficially
owned by Stockholder and shall be binding upon any person to which legal or beneficial ownership of
such Stockholder Shares or New Shares shall pass, whether by operation of law or otherwise,
including, without limitation, Stockholder’s heirs, guardians, administrators, successors or
assigns.

          27. Ownership of Shares. Nothing contained in this Agreement shall be deemed, upon
execution, to vest in Parent any direct or indirect ownership or incidence of ownership of or with
respect to any Stockholder Shares or any New Shares. All rights, ownership and economic benefits
of and relating to the Stockholder Shares and any New Shares shall remain vested in and belong to
Stockholder, and Parent shall have no authority to manage, direct, superintend, restrict, regulate,
govern or administer any of the policies or operations of the Company or exercise any power or
authority to direct Stockholder in the voting of any of the Stockholder Shares or any New Shares,
except as otherwise provided herein.

          28. Expenses. All costs and expenses incurred in connection with this Agreement and
the transactions contemplated by this Agreement will be paid by the party incurring such expense.

          29. Headings. The section headings set forth in this Agreement are for convenience of
reference only and shall not affect the construction or interpretation of this Agreement in any
manner.

each Loan made to the Borrower by the Lender as provided in Section 2.06.

     (b) The Lender may maintain an accounting evidencing the indebtedness of the Borrower to the
Lender resulting from the Loans made by the Lender to the Borrower under this

13

 

Agreement from time to time, including the amounts of principal and interest payable and paid
to the Lender from time to time under this Agreement.

     (c) The entries made in the accounting maintained pursuant to paragraph (b) of this Section
shall be prima facie evidence of the existence and amounts of the obligations therein recorded;
provided, however, that the failure of the Lender to maintain such accounts or any error therein
shall not in any manner affect the obligations of the Borrower to repay the Loans made to the

but excluding the date of payment. All repayments pursuant to this Section 2.06 shall be
without premium or penalty.

     SECTION 2.07. Voluntary Prepayments. Subject to the last sentence of this Section
2.07, the Borrower may, at any time and from time to time, prepay the Loans in whole or in part
upon at least five (5) Business Days’ prior written notice to the Lender; provided,
however, that any partial prepayment shall be in the minimum amount of $500,000 and
integral multiples of $250,000 in excess thereof. Any notice of prepayment given to the Lender
under this Section 2.07 shall specify (i) the date (which shall be a Business Day) of
prepayment and (ii) the aggregate principal amount of the prepayment. When notice of prepayment is

Notwithstanding anything in this Section 2.07 to the contrary, the Borrower may not
voluntarily prepay the Loans (i) prior to the Definitive Agreement Termination Date or (ii) at any
time prior to the consummation of a Change of Control, if a Superior Proposal Termination shall

of or interest on the Loans or other amounts) hereunder and under any other Loan Document not later
than 12:00 p.m. New York time, on the date when due in immediately available funds, without setoff,
defense or counterclaim. For purposes of computing interest, funds received by the Lender after
that time on such due date shall be deemed to have been paid by the Borrower on the next succeeding
Business Day, in the Lender’s sole discretion. Each such payment shall be made to the Lender at
its address specified in Section 9.01. All payments hereunder and under each other Loan
Document shall be made in Dollars.

     (b) Except as otherwise expressly provided herein, whenever any payment (including principal
of or interest on any Loan or other amounts) hereunder or under any other Loan Document shall
become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made
on the next succeeding Business Day, and such extension of time shall in such case be included in
the computation of interest, if applicable.

     SECTION 2.10. Conversion of Loans. (a) From and after the Definitive Agreement Termination
Date, the Lender may convert the Convertible Portion of its Loans in whole or in part into Common
Stock at any time prior to 5:00 p.m. New York time on the Business Day immediately preceding the
Maturity Date into a number of whole shares of Common Stock equal to the Convertible Portion of the
Loans divided by the applicable Conversion Rate in effect on the date the Conversion Notice is
delivered; provided that with respect to any conversion of the Convertible Portion of the Loans
into Common Stock that would be subject to a waiting period provided by the HSR Act, no such
conversion shall be considered effective until the expiration or termination of such waiting
period; provided further that the Borrower agrees to use its commercially reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and
cooperate with the other parties hereto in doing, all things necessary to consummate and make
effective the conversion contemplated by this Section 2.10.

     (b) The Convertible Portion of the Loans delivered for conversion will be deemed to have been
converted immediately prior to 5:00 p.m. New York time on the Loan Conversion Date. The Lender
shall be entitled to rights with regard to the Common Stock only to the extent such Convertible
Portion of Loans has been converted (or deemed to have converted) into Common Stock pursuant
hereto.

15

 

     (c) The right of conversion attaching to the Convertible Portion of any Loan may be exercised
(i) if such Loan is not represented by a promissory note, by book-entry transfer by the Lender, or
(ii) if such Loan is represented by a promissory note, by delivery of such promissory note to the
Borrower, accompanied, in either case, by: (1) a duly signed and completed Conversion Notice, in
the form as set forth as Exhibit B (a “Conversion Notice”), which Conversion Notice
shall specify the Convertible Portion of such Loan to be converted; (2) if any promissory note has
been lost, stolen, destroyed or mutilated, a notice to the Borrower regarding the loss, theft,
destruction or mutilation of the promissory note together with reasonable indemnity for the
Borrower; (3) appropriate endorsements and transfer documents if reasonably required by the
Borrower; and (4) payment of any transfer tax due that is payable solely as a result of the issue,
delivery or registration of the Common Stock in the name of a Person other than the Lender. The
date on which the Lender satisfies all of the requirements in the immediately preceding sentence is
the “Loan Conversion Date.” Notwithstanding any other provision of this Agreement, the
Borrower may not, and shall not, redeem or prepay any Loans (or any portion thereof) with respect
to which a Conversion Notice has been delivered to the Borrower. The Borrower shall deliver to the
Lender the number of whole shares of Common Stock issuable upon the conversion of the Convertible
Portion of the Loans in accordance with Section 2.10(a) (and cash in lieu of any fractional
shares) no later than five (5) Business Days following the relevant Loan Conversion Date. All such
shares shall be fully paid, duly authorized and issued and nonassesable.

     (d) Upon conversion of a Loan and receipt of Common Stock issued upon conversion of the
Convertible Portion of the Loans, the recipient of such Common Stock shall no longer be the Lender
to the extent of such converted Loan. No adjustment will be made to the Conversion Rate for
accrued and unpaid interest on a converted Loan except as provided herein.

     (e) Upon surrender of a Loan evidenced by a promissory note that is converted in part, the
Borrower shall execute and deliver to the Lender a new note evidencing the Loan equal in principal
amount to the unconverted portion of the Loan promissory note surrendered.

     SECTION 2.11. Conversion of Escrow Funds . (a) From and after the Definitive Agreement
Termination Date, the Lender may convert any Escrow Funds in whole or in part into Common Stock at
any time prior to 5:00 p.m. New York time on the Business Day immediately preceding the Maturity
Date into a number of whole shares of Common Stock equal to the Escrow Funds delivered for
conversion divided by the applicable Conversion Rate; provided that with respect to any conversion
of any Escrow Funds into Common Stock that would be subject to a waiting period provided by the HSR
Act, no such conversion shall be considered effective until the expiration or termination of such
waiting period; provided further that the Borrower agrees to use its commercially reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties hereto in doing, all things necessary to consummate and make
effective the conversion contemplated by this Section 2.11.

     (b) Any Escrow Funds delivered for conversion will be deemed to have been converted
immediately prior to 5:00 p.m. New York time on Escrow Amount Conversion Date. The Lender shall be
entitled to rights with regard to the Common Stock only to the extent such

16

 

Escrow Funds have been converted (or deemed to have converted) into Common Stock pursuant hereto.

     (c) The right of conversion attaching to any Escrow Funds may be exercised if the Lender shall
have delivered (i) a Conversion Notice, which Conversion Notice shall specify the Escrow Funds to
be converted and (ii) payment of any transfer tax due that is payable solely as a result of the
issue, delivery or registration of the Common Stock in the name of a Person other than the Lender.
The date on which the Lender satisfies all of the requirements in the immediately preceding
sentence is the “Escrow Amount Conversion Date.” Upon receipt by the Borrower of the
Escrow Funds delivered for conversion in accordance with Section 2.11(a), the Borrower
shall deliver to the Lender the number of whole shares of Common Stock issuable upon the conversion
thereof (and cash in lieu of any fractional shares) no later than five (5) Business Days following
the relevant Escrow Amount Conversion Date. All such shares shall be fully paid, duly authorized
and issued and nonassesable.

     (d) Upon delivery of the Escrow Funds to Borrower and receipt of Common Stock by the Lender,
(i) the Commitment of the Lender shall be reduced by the amounts so converted and (ii) such amounts
shall no longer be available to the Borrower for Borrowings hereunder.

     SECTION 2.12. Maximum Amount of Converted Common Stock . Notwithstanding anything in
Section 2.10, Section 2.11 or in any other Loan Document, for so long as the
Borrower’s CHESS Depositary Receipts are listed on the ASX, no more than 14.99% in the aggregate of
the then authorized and outstanding shares of Common Stock as of the date of any conversion in
accordance with Section 2.10 or Section 2.11 (without giving effect to such
conversion) shall be issued to the Lender hereunder.

     SECTION 2.13. Adjustment of Conversion Rate . If at any time between (i) the execution of
this Agreement and (ii) the date on which all amounts outstanding under this Agreement are paid by
Borrower and/or all of the Loans and any Escrow Funds have been converted into Common Stock as
provided herein, the number of outstanding shares of Common Stock shall (A) increase by virtue of
or in connection with any dividend or distribution on the Common Stock or any stock split or other
subdivision of the outstanding shares of Common Stock or a reclassification, then the Conversion
Rate in effect immediately prior to such dividend, distribution, stock split or other subdivision
shall, concurrently with the effectiveness of such increase, be adjusted to a Conversion Rate that
would entitle the holder of any Loans and any Escrow Funds delivered for conversion to receive,
from time to time upon conversion thereof, the same percentage of the outstanding shares of Common
Stock that such holder would have received on conversion thereof had such Loan or Escrow Funds been
outstanding and converted immediately prior to such increase and (B) decrease by virtue of or in
connection with any combination or consolidation, by reclassification or otherwise, into a lesser
number of shares of Common Stock (including, without limitation, pursuant to a reverse stock
split), then the Conversion Rate in effect immediately prior to such combination, consolidation,
reclassification, stock split or other process shall, concurrently with the effectiveness of such
decrease, be adjusted to a Conversion Rate that would entitle the holder of any Loans and any
Escrow Funds delivered for conversion to receive, from time to time upon conversion, the same
percentage of the outstanding shares of Common Stock that such holder would have received on
conversion

17

 

thereof had such Loan or Escrow Funds been outstanding and converted immediately prior to such
decrease.

Definitive Agreement in accordance with its terms, the Borrower shall use the proceeds of the Loans
only (i) in the ordinary course of its business consistent with past practice, and to pay NASDAQ
related expenses and any expenses incurred in connection with the transactions contemplated by the
Definitive Agreement and (ii) to lend money directly to any Subsidiary for use by such Subsidiary
only in the ordinary course of business in accordance with the Capital Expenditure and Loan
Proceeds Budget (as such term is defined in the Definitive Agreement) and shall not authorize any
expenditures of the proceeds of the Loans that, in the aggregate, exceed any specific line item set
forth in the Capital Expenditure and Loan Proceeds Budget (as such term is defined in the
Definitive Agreement).

     SECTION 6.03. Further Assurances. Each Loan Party shall, from time to time, duly
authorize, execute and deliver, or cause to be duly authorized, executed and delivered, such
additional instruments, certificates, agreements or documents, and take all such actions, as the
Lender may reasonably request or as may be necessary, for the purposes of implementing or
effectuating the provisions of this Agreement and the other Loan Documents. Upon the exercise by
the Lender of any power, right, privilege or remedy pursuant to this Agreement or the other Loan
Documents which requires any consent, approval, recording, qualification or authorization of any
Governmental Authority, each Loan Party will execute and deliver, or will cause the execution and
delivery of, all applications, certifications, instruments and other documents and

22

 

papers that the Lender may be required to obtain from it for such governmental consent,
approval, recording, qualification or authorization.

     SECTION 6.04. Taxes. (a) All sums payable by or on behalf of any Loan Party hereunder and
under the other Loan Documents shall (except to the extent required by law) be paid free and clear
of, and without any deduction or withholding on account of, any Tax (excluding any income or
franchise Tax imposed on the net income of the Lender by the United States of America or any
political subdivision thereof). So long as Thoratec Corporation is the Lender and the Lender has
complied with Section 6.04(b), if the Borrower shall be required to deduct any such
non-excluded Taxes from such payments, then (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to additional sums
payable under this Section) the Lender receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

     (b) On or prior to the Closing Date, the Lender shall deliver to the Borrower a properly
completed and duly executed Internal Revenue Service Form W-9 (or any subsequent versions thereof
or successors thereto). Any permitted assignee pursuant to Section 9.04(b) shall, on or
prior to such assignment, deliver to the Borrower a properly completed and duly executed Internal
Revenue Service Form W-9 (or any subsequent versions thereof or successors thereto) or applicable
Internal Revenue Service Form W-8 (or any subsequent versions thereof or successors thereto).

     (c) The Borrower shall pay any Other Taxes.

     SECTION 6.05. Compliance with Laws. Each Loan Party will comply in all material respects
with the requirements of all applicable laws, rules, regulations and orders of any Governmental
Authority in performing its obligations under this Agreement and the other Loan Documents.

     SECTION 6.06. Common Stock. (a) The Borrower shall, at all times prior to the Maturity
Date, and from time to time thereafter as may be necessary, reserve at all times and keep
available, free from preemptive rights, out of its authorized but unissued Common Stock, a
sufficient number of shares of Common Stock such that the Borrower shall be able to deliver at any
time and from time to time following the date hereof all of the shares of Common Stock that would
be deliverable upon conversion of all of the Convertible Portion of the Loans and Escrow Funds
pursuant to Section 2.10 and Section 2.11.

     (b) The Borrower shall take all actions necessary to ensure that all shares of Common Stock
that may be issued upon conversion of any Loans and/or Escrow Funds shall be (i) newly issued
shares or shares held in the treasury of the Borrower, (ii) duly authorized, validly issued, fully
paid and nonassessable and (iii) free of any preemptive rights, lien or adverse claim.

ARTICLE VII.

Guaranty

     SECTION 7.01. Guaranty of the Obligations. (a) Guarantors jointly and severally hereby
irrevocably and unconditionally guaranty to the Lender the due and punctual payment in full of all
Obligations when the same shall become due, whether at stated maturity, by required prepayment,
declaration, acceleration, demand or otherwise (including amounts that would become due but for the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code) (collectively, the
“Guaranteed Obligations”).

     (b) Each Guarantor and the Lender hereby confirms that it is the intention of all such Persons
that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent
transfer or conveyance for purposes of any law related to fraudulent transfer or conveyance to the
extent applicable to this Guaranty and the Obligations of the Guarantor hereunder. To effectuate
the foregoing intention, the Lender and the Guarantors hereby irrevocably agree that the
Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum
amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a
fraudulent transfer or conveyance.

     SECTION 7.02. Payment by Guarantors. Guarantors hereby jointly and severally agree, in
furtherance of the foregoing and not in limitation of any other right which the Lender may have at
law or in equity against any Guarantor by virtue hereof, that upon the failure of Borrower to pay
any of the Guaranteed Obligations when and as the same shall become due, whether at stated
maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts
that would become due but for the operation of the automatic stay under Section 362(a) of the
Bankruptcy Code), Guarantors will upon demand pay, or cause to be paid, in cash, to the Lender, an
amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as
aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which,
but for Borrower’s becoming the subject of a case under the Bankruptcy Code, would have accrued on
such Guaranteed Obligations, whether or not a claim is allowed against Borrower for such interest
in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Lenders as
aforesaid.

     SECTION 7.03. Liability of Guarantors Absolute. Each Guarantor agrees that its obligations
hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any
circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than
payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without
limiting the generality thereof, each Guarantor agrees as follows:

          (a) this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty
is a primary obligation of each Guarantor and not merely a contract of surety;

          (b) the Lender may enforce this Guaranty upon the occurrence of an Event of Default
notwithstanding the existence of any dispute between Borrower and the Lender with respect to the
existence of such Event of Default;

24

 

          (c) the obligations of each Guarantor hereunder are independent of the obligations of
Borrower and the obligations of any other guarantor (including any other Guarantor) of the
obligations of Borrower, and a separate action or actions may be brought and prosecuted against
such Guarantor whether or not any action is brought against Borrower or any of such other
guarantors and whether or not Borrower is joined in any such action or actions;

          (d) payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall
in no way limit, affect, modify or abridge any Guarantor’s liability for any portion of the
Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing,
if the Lender is awarded a judgment in any suit brought to enforce any Guarantor’s covenant to pay
a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such
Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the
subject of such suit, and such judgment shall not, except to the extent satisfied by such
Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of
the Guaranteed Obligations;

          (e) the Lender, upon such terms as it deems appropriate, without notice or demand and without
affecting the validity or enforceability hereof or giving rise to any reduction, limitation,
impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may
(i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time,
place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release
or discharge, or accept or refuse any offer of performance with respect to, or substitutions for,
the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the
same to the payment of any other obligations; (iii) request and accept other guaranties of the
Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed
Obligations; and (iv) exercise any other rights available to it under the Loan Documents; and

          (f) this Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable
and shall not be subject to any reduction, limitation, impairment, discharge or termination for any
reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any
of the following, whether or not any Guarantor shall have had notice or knowledge of any of them:
(i) any failure or omission to assert or enforce or agreement or election not to assert or enforce,
or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or
enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan
Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any
agreement relating thereto, or with respect to any other guaranty of the payment of the Guaranteed
Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure
from, any of the terms or provisions (including provisions relating to Events of Default) hereof,
any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any
other guaranty for the Guaranteed Obligations, in each case whether or not in accordance with the
terms hereof or such Loan Document or any agreement relating to such other guaranty; (iii) the
Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal,
invalid or unenforceable in any respect; (iv) the application of payments received from any source
(other than payments received pursuant to the other Loan Documents) to the payment of indebtedness
other than the Guaranteed Obligations, even though the Lender might have elected to apply such
payment to

25

 

any part or all of the Guaranteed Obligations; (v) the Lender’s consent to the change,
reorganization or termination of the corporate structure or existence of Borrower or any of its
Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any
defenses, set offs or counterclaims which Borrower may allege or assert against the Lender in
respect of the Guaranteed Obligations, including failure of consideration, breach of warranty,
payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (vii)
any other act or thing or omission, or delay to do any other act or thing, which may or might in
any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the
Guaranteed Obligations.

     SECTION 7.04. Waivers by Guarantors. Each Guarantor hereby waives, for the benefit of the
Lender: (a) any right to require the Lender, as a condition of payment or performance by such
Guarantor, to (i) proceed against Borrower, any other guarantor (including any other Guarantor) of
the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held
from Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort
to any balance of any deposit account or credit on the books of the Lender in favor of Borrower or
any other Person, or (iv) pursue any other remedy in the power of the Lender whatsoever; (b) any
defense arising by reason of the incapacity, lack of authority or any disability or other defense
of Borrower or any other Guarantor including any defense based on or arising out of the lack of
validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument
relating thereto or by reason of the cessation of the liability of Borrower or any other Guarantor
from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon
any statute or rule of law which provides that the obligation of a surety must be neither larger in
amount nor in other respects more burdensome than that of the principal; (d) any defense based upon
the Lender’s errors or omissions in the administration of the Guaranteed Obligations, except
behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or
otherwise, which are or might be in conflict with the terms hereof and any legal or equitable
discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations
affecting such Guarantor’s liability hereunder or the enforcement hereof, and (iii) any rights to
set offs, recoupments and counterclaims; (f) notices, demands, presentments, protests, notices of
protest, notices of dishonor and notices of any action or inaction, including acceptance hereof,
notices of default hereunder, notices of any renewal, extension or modification of the Guaranteed
Obligations or any agreement related thereto, notices of any extension of credit to Borrower and
notices of any of the matters referred to in Section 7.03 and any right to consent to any
thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit
the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

     SECTION 7.05. Guarantors’ Rights of Subrogation, Contribution, Etc. Until the Guaranteed
Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated,
each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such Guarantor
now has or may hereafter have against Borrower or any other Guarantor or any of its assets in
connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in
each case whether such claim, right or remedy arises in equity, under contract, by statute, under
common law or otherwise and including (a) any right of subrogation, reimbursement or
indemnification that such Guarantor now has or may hereafter have against Borrower with respect to
the Guaranteed Obligations, and (b) any right to enforce, or to

26

 

participate in, any claim, right or remedy that the Lender now has or may hereafter have against
Borrower. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full
and the Commitments shall have terminated, each Guarantor shall withhold exercise of any right of
contribution such Guarantor may have against any other guarantor (including any other Guarantor) of
the Guaranteed Obligations. Each Guarantor further agrees that, to the extent the waiver or
agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and
contribution as set forth herein is found by a court of competent jurisdiction to be void or
voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor
may have against Borrower, and any rights of contribution such Guarantor may have against any such
other guarantor, shall be junior and subordinate to any rights the Lender may have against Borrower
to any right the Lender may have against such other guarantor. If any amount shall be paid to any
Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights
at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in
full, such amount shall be held in trust for the Lender and shall forthwith be paid over to the
Lender to be credited and applied against the Guaranteed Obligations, whether matured or unmatured,
in accordance with the terms hereof.

     SECTION 7.06. Subordination of Other Obligations. Any Indebtedness of Borrower or any
Guarantor now or hereafter held by any Guarantor (the “Obligee Guarantor”) is hereby
subordinated in right of payment to the Guaranteed Obligations, and any such Indebtedness collected
or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall
be held in trust for the Lender and shall forthwith be paid over to the Lender to be credited and
applied against the Guaranteed Obligations but without affecting, impairing or limiting in any
manner the liability of the Obligee Guarantor under any other provision hereof.

     SECTION 7.07. Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain
in effect until all of the Guaranteed Obligations shall have been paid in full and the Commitments
shall have terminated. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty
as to future transactions giving rise to any Guaranteed Obligations.

     SECTION 7.08. Authority of Guarantors or Borrower. It is not necessary for the Lender to
inquire into the capacity or powers of any Guarantor or Borrower or the officers, directors or any
agents acting or purporting to act on behalf of any of them.

     SECTION 7.09. Financial Condition of Borrower. Any Loan may be made to Borrower or
continued from time to time without notice to or authorization from any Guarantor regardless of the
financial or other condition of Borrower at the time of any such grant or continuation. The Lender
shall have no obligation to disclose or discuss with any Guarantor its assessment, or any
Guarantor’s assessment, of the financial condition of Borrower. Each Guarantor has adequate means
to obtain information from Borrower on a continuing basis concerning the financial condition of
Borrower and its ability to perform its obligations under the Loan Documents and each Guarantor
assumes the responsibility for being and keeping informed of the financial condition of Borrower
and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Each
Guarantor hereby waives and relinquishes any duty on the part of the Lender to disclose any matter,
fact or thing relating to the business, operations or conditions of Borrower now known or hereafter
known by the Lender.

27

 

     SECTION 7.10. Bankruptcy, Etc. (a) So long as any Guaranteed Obligations remain
outstanding, no Guarantor shall, without the prior written consent of the Lender, commence or join
with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding
of or against Borrower or any other Guarantor. The obligations of Guarantors hereunder shall not
be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or
proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership,
reorganization, liquidation or arrangement of Borrower or any other Guarantor or by any defense
which Borrower or any other Guarantor may have by reason of the order, decree or decision of any
court or administrative body resulting from any such proceeding.

          (b) Each Guarantor acknowledges and agrees that any interest on any portion of the
Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to
in clause (a) above (or, if interest on any portion of the Guaranteed Obligations ceases to accrue
by operation of law by reason of the commencement of such case or proceeding, such interest as
would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not
been commenced) shall be included in the Guaranteed Obligations because it is the intention of
Guarantors and the Lender that the Guaranteed Obligations which are guaranteed by Guarantors
pursuant hereto should be determined without regard to any rule of law or order which may relieve
Borrower of any portion of such Guaranteed Obligations. Guarantors will permit any trustee in
bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar Person
to pay the Lender, or allow the claim of the Lender in respect of, any such interest accruing after
the date on which such case or proceeding is commenced.

          (c) In the event that all or any portion of the Guaranteed Obligations are paid by Borrower,
the obligations of Guarantors hereunder shall continue and remain in full force and effect or be
reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded
or recovered directly or indirectly from the Lender as a preference, fraudulent transfer or
otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed
Obligations for all purposes hereunder.

ARTICLE VIII.

Events of Default

     (a) any representation or warranty made in any Loan Document, shall prove to have been false
or misleading in any material respect when so made, deemed made or furnished;

shall become due and payable, whether at the due date thereof or at a date fixed for prepayment

period of three (3) Business Days;

covenant, condition or agreement contained in Section 2.10 or Section 2.11, and

     (e) the Borrower shall fail to comply in all material respects with any covenant, condition or
agreement contained in any Loan Document (other than those specified in clauses (b), (c) or (d)

     (f) the Borrower shall default in the observance or performance of any agreement or condition
relating to any Indebtedness (including any Guarantee of Indebtedness) exceeding $5,000,000 in
aggregate principal and accrued interest, or contained in any instrument or agreement evidencing,
securing or relating thereto, or any other event shall occur or condition exist (other than (x) any
disposition of assets giving rise to a repayment or prepayment obligation on Indebtedness secured
by such assets and (y) the issuance of Equity Interests or Indebtedness giving rise to a repayment
obligation with respect to the proceeds of such issuance, provided in each case such payment is
timely made), the effect of which default or other event or condition is to cause such Indebtedness
to become due prior to its stated maturity or (in the case of any Guarantee of Indebtedness) to
become due or payable in respect of any such accelerated Indebtedness;

     (g) an involuntary proceeding shall be commenced or an involuntary petition shall be filed in
a court of competent jurisdiction seeking (i) relief in respect of the Borrower , or of a
substantial part of the property or assets of the Borrower under the Bankruptcy Code, as now
constituted or hereafter amended, or any other Federal, state or foreign bankruptcy, insolvency,
receivership or similar law, (ii) the appointment of a receiver, trustee, custodian, sequestrator,
conservator or similar official for the Borrower or for a substantial part of the property or
assets of the Borrower or (iii) the winding-up or liquidation of the Borrower; and such proceeding
or petition shall continue undismissed for 60 days or an order or decree approving or ordering any
of the foregoing shall be entered;

     (h) the Borrower shall (i) voluntarily commence any proceeding or file any petition seeking
relief under the Bankruptcy Code, as now constituted or hereafter amended, or any other Federal,
state or foreign bankruptcy, insolvency, receivership or similar law, (ii) consent to the
institution of, or fail to contest in a timely and appropriate manner, any proceeding or the filing
of any petition described in (g) above, (iii) apply for or consent to the appointment of a
receiver, trustee, custodian, sequestrator, conservator or similar official for the Borrower or for
a substantial part of the property or assets of the Borrower, (iv) file an answer admitting the
material allegations of a petition filed against it in any such proceeding, (v) make a general
assignment for the benefit of creditors, (vi) admit in writing its inability or fail generally to
pay its debts as they become due or (vii) take any action for the purpose of effecting any of the
foregoing;

     (i) one or more judgments for the payment of money that, individually or in the aggregate,
would reasonably be expected to result in a Company Material Adverse Effect shall

29

 

be rendered against the Borrower or any combination thereof and the same shall remain
undischarged for a period of thirty (30) consecutive days during which execution shall not be
effectively stayed, or any action shall be legally taken by a judgment creditor to levy upon assets
or properties of the Borrower to enforce any such judgment; or

     (j) the Borrower shall fail to repay on the date required pursuant to Section 2.06 the
entire principal amount of and accrued interest on the Loans,

then, and in every such event (other than an event with respect to the Borrower described in
paragraph (g) or (h) above), and at any time thereafter during the continuance of such event either
or both of the following actions may be taken: the Lender by notice to the Borrower may declare
the Loans then outstanding to be forthwith due and payable in whole or in part, whereupon the
principal of the Loans so declared to be due and payable, together with accrued interest thereon
and all other liabilities of the Borrower accrued hereunder and under any other Loan Document,
shall become forthwith due and payable, without presentment, demand, protest or further notice of
any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in
any other Loan Document to the contrary notwithstanding, and the Lender shall have the right to
take all or any actions and exercise any remedies available to them under this Agreement,
applicable law or in equity; and in any event with respect to the Borrower described in
paragraph (g) or (h) above, the principal of the Loans then outstanding, together with accrued
interest thereon and all other liabilities of the Borrower accrued hereunder and under any other
Loan Document, shall automatically become due and payable, without presentment, demand, protest or
any other notice of any kind, all of which are hereby expressly waived by the Borrower, anything
contained herein or in any other Loan Document to the contrary notwithstanding, and the Lender
shall have the right to take all or any actions and exercise any remedies available to them under
this Agreement, applicable law or in equity.

32

 

Treasury Regulations (and any successor provisions) at all times during which the Loans remain
in effect. Neither the Borrower nor the Lender shall take any action or otherwise permit such
obligation to become an obligation that is not in “registered form.” The Borrower shall maintain a
register for the recordation of the name and address of the Lender (and any permitted assignees
pursuant to Section 9.04(b)) and principal and interest shall only be paid to such persons
recorded in the register. The register is intended to function as a “book entry” system within the
meaning of sections 5f.103-1(c)(1)(ii) and 5f.103–1(c)(2) of the Treasury Regulations (and any
successor provisions).

     SECTION 9.05. Right of Setoff. If an Event of Default shall have occurred and be
continuing, the Lender is hereby authorized at any time and from time to time, except to the extent
prohibited by law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing by the Lender to or
for the credit or the account of the Borrower against any of and all the obligations of the
Borrower now or hereafter existing under this Agreement and other Loan Documents held by the
Lender, irrespective of whether or not the Lender shall have made any demand under this Agreement
or such other Loan Document and although such obligations may be unmatured. The rights of the
Lender under this Section 9.05 are in addition to other rights and remedies (including
other rights of setoff) which the Lender may have.

     SECTION 9.06. Applicable Law. THIS AGREEMENT AND THE NOTES SHALL BE CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES THEREOF.

     SECTION 9.07. Waivers; Amendment. (a) No failure or delay of the Lender in exercising
any power or right hereunder or under any other Loan Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of the Lender
hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or
remedies that it would otherwise have. No waiver of any provision of this Agreement or any other
Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective
unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No notice or demand
on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances.

     (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower and the Lender.

     SECTION 9.08. Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges
and other amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such Loan or

33

 

participation in accordance with applicable law, the rate of interest payable in respect of
such Loan or participation hereunder, together with all Charges payable in respect thereof, shall
be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan or participation but were not payable as a result of the
operation of this Section 9.08 shall be cumulated and the interest and Charges payable to
the Lender in respect of other Loans or participations or periods shall be increased (but not above
the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the
Federal Funds Effective Rate to the date of repayment, shall have been received by the Lender.

     SECTION 9.09. Entire Agreement. This Agreement, the other Loan Documents, the
Definitive Agreement and the other documents contemplated hereby and thereby constitute the entire
contract between the parties relative to the subject matter hereof. Any other previous agreement
among the parties with respect to the subject matter hereof is superseded by this Agreement, the
other Loan Documents, the Definitive Agreement and the other documents contemplated hereby and
thereby. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is
intended to confer upon any person (other than the parties hereto and thereto, their respective
successors and assigns permitted hereunder and, to the extent expressly contemplated hereby, the
Related Parties of the Lender) any rights, remedies, obligations or liabilities under or by reason
of this Agreement or the other Loan Documents.

     SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY
OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 9.10.

     SECTION 9.11. Severability. In the event any one or more of the provisions contained
in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein and therein shall not in
any way be affected or impaired thereby (it being understood that the invalidity of a particular
provision in a particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect
of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

     SECTION 9.12. Counterparts. This Agreement may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall constitute an original but
all of which when taken together shall constitute a single contract, and shall become effective as
provided in Section 9.03. Delivery of an executed signature page to this Agreement by
facsimile

34

 

or other electronic transmission shall be as effective as delivery of a manually signed
counterpart of this Agreement.

     SECTION 9.13. Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and are not to affect
the construction of, or to be taken into consideration in interpreting, this Agreement.

     SECTION 9.14. Jurisdiction; Consent to Service of Process. (a) The Borrower and the
Lender each irrevocably and unconditionally submits, for itself and its property, to the exclusive
jurisdiction of any New York State court or Federal court of the United States of America sitting
in the Borough of Manhattan, New York, New York and any appellate court from any thereof, in any
action or proceeding arising out of or relating to this Agreement, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard and determined in
such New York State or, to the extent permitted by law, in such Federal court sitting in the
Borough of Manhattan, New York, New York. Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

     (a) Each party hereto hereby irrevocably and unconditionally waives, to the fullest extent it
may legally and effectively do so, any objection which it may now or hereafter have to the laying
of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New
York State or Federal court sitting in the Borough of Manhattan, New York, New York. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such court.

     (b) Each party to this Agreement irrevocably consents to service of process in the manner
provided for notices in Section 9.01. Nothing in this Agreement will affect the right of
any party to this Agreement to serve process in any other manner permitted by law.

     SECTION 9.15. No Fiduciary Duty. The Lender and its Affiliates (collectively, solely
for purposes of this paragraph, the “Lender”), may have economic interests that conflict
with those of the Borrower. The Borrower agrees that nothing in the Loan Documents or otherwise
will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other
implied duty between the Lender and the Borrower, its stockholders or its affiliates. The Borrower
acknowledge and agree that (i) the transactions contemplated by the Loan Documents are arm’s-length
commercial transactions between the Lender, on the one hand, and the Borrower, on the other, (ii)
in connection therewith and with the process leading to such transaction the Lender is acting
solely as a principal and not the agent or fiduciary of the Borrower, its management, stockholders,
creditors or any other Person, (iii) the Lender has not assumed an advisory or fiduciary
responsibility in favor of the Borrower with respect to the transactions contemplated hereby or the
process leading thereto (irrespective of whether the Lender or any of its affiliates has advised or
is currently advising the Borrower on other matters) or any other obligation to the Borrower except
the obligations expressly set forth in the Loan Documents and (iv) the Borrower has consulted its
own legal and financial advisors to the extent they deemed appropriate. The Borrower further
acknowledges and agrees that it is responsible for making its own independent

35

 

judgment with respect to such transactions and the process leading thereto. The Borrower
agrees that it will not claim that the Lender has rendered advisory services of any nature or
respect, or owes a fiduciary or similar duty to the Borrower, in connection with such transaction
or the process leading thereto.

     SECTION 9.16. Payments Set Aside. To the extent that any payment by or on behalf of
the Borrower is made to the Lender, or the Lender exercises its right of setoff, and such payment
or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any settlement entered
into by the Lender in its discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any bankruptcy or insolvency law or otherwise, then to the
extent of such recovery, 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
setoff had not occurred.
