To the extent that any Purchased Assets are not delivered at the Closing, Seller agrees to use commercially reasonable efforts to preserve and maintain the tangible Purchased Assets in good working condition and to protect such Purchased Assets against spoilage, deterioration and other wasting.

7.2 Transition Services and Expenses.

Prior to the Effective Date, Seller and its employees have been engaged in activities, including the purchase of materials that will aid in the orderly transfer of the Purchased Assets and will enhance Buyer’s ability to effectively utilize the Purchased Assets that Buyer has acquired from Seller. To this effect Buyer has agreed to reimburse Seller $ 5,750.00 for the time expended by Seller’s employees, expenses incurred for the acquisition of materials and out-of-pocket costs incurred by Seller in these efforts with said amount being due and payable at Closing (the “Pre-Closing Services and Expenses”). Following the Closing, to assist Buyer in the orderly transfer of the Purchased Assets and the accomplishment of the diligence requirements set forth in Section 7.3 below, Buyer and Seller shall use commercially reasonable efforts to allow and cause Buyer to enter into agreements with former or current Seller personnel, including but not limited to ▇▇▇▇ ▇▇▇▇▇▇▇, an employee and senior chemist for Seller, to assist in the transfer of the Technical Information and the installation of the equipment included within the Purchased Assets and the validation of the SPUS manufacturing process at Buyer.

For a period of not more than four (4) months from the Effective Date, Seller shall accommodate such reasonable requests as necessary and permit such personnel to take un-paid leaves of absence or personal time to perform services requested by Buyer.

7.3 Buyer Diligence Obligations.

Upon execution of this Agreement, Buyer shall proceed with Commercially Reasonable Diligent Efforts to complete each of the events triggering the additional payments to Seller set forth in Sections 3.1(b), (c) and (d) above. To that effect, Buyer shall accomplish the following obligations as part of its diligence obligations hereunder:

(a) Buyer shall complete the installation of the Reactor at Buyer’s premises within forty-five (45) days of the Effective Date.

(b) Buyer shall produce the first batch of non-clinical grade SPUS within seventy-five (75) days of the Effective Date.

(c) Buyer shall produce the first batch of clinical grade SPUS within one hundred and five (105) days of the Effective Date.

If Buyer fails to meet any of the foregoing diligence obligations, then, except to the extent such failure is not caused by Seller’s delay, action or inaction, upon the payment of the applicable extension fee set forth below Seller will grant to Buyer, upon Buyer’s request, a one-time thirty (30) day extension of time to meet Buyer’s missed diligence commitment. The first request for a thirty (30) day extension of time to meet Buyer’s diligence commitments shall require the payment of Twenty-Five Thousand Dollars ($25,000.00) by Buyer to Seller. The second request for a thirty (30) day extension of time to meet Buyer’s diligence commitments shall require the payment of Fifty Thousand Dollars ($50,000.00) by Buyer to Seller. The third request for a thirty (30) day extension of time to meet Buyer’s diligence commitment shall require the payment of Seventy-Five Thousand Dollars ($75,000.00) by Buyer to Seller.

For clarification, if Buyer makes payment to extend the time to meet a diligence commitment described in Section 7.3(a) or (b) for thirty (30) days as described above, thereafter the time in which Buyer is required to meet all subsequent diligence commitments shall automatically be extended by thirty (30) days without additional payment. For example, if Buyer is unable to install the Reactor within forty-five (45) days of the Effective Date and makes the first Twenty-Five Thousand Dollar ($25,000) payment to extend the time to complete the installation of the Reactor to seventy-five (75) days from the Effective Date, automatically and without additional payment, the time in which Buyer must produce the first batch of non-clinical grade SPUS shall thereafter be one hundred five (105) days from the Effective Date and the time in which Buyer must produce the first batch of clinical grade SPUS shall be one hundred thirty five (135) days from the Effective Date. If, after the grant of the first thirty (30) day extension Buyer is not able to meet any of the revised diligence achievement dates and desires to extend such date by another thirty (30) days, the second extension fee shall be Fifty Thousand Dollars ($50,000.00), and the third extension fee shall be Seventy-five Thousand Dollars ($75,000.00).

(a) The Escrow Agent shall have only those duties as are specifically and expressly provided herein, which shall be deemed purely ministerial in nature, and no other duties shall be implied. The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of, nor have any requirements to comply with, the terms and conditions of any other agreement, instrument or document between the Parties, in connection herewith, if any, including without limitation the APA (each an “Underlying Agreement”), nor shall the Escrow Agent be required to determine if any person or entity has complied with any Underlying Agreement, nor shall any additional obligations of the Escrow Agent be inferred from the terms of any Underlying Agreements, even though reference thereto may be made in this Agreement. In the event of any conflict between the terms and provisions of this Agreement, those of any Underlying Agreement, any schedule or exhibit attached to the Agreement, or any other agreement among the Parties, the terms and conditions of this Agreement shall control. The Escrow Agent may rely upon and shall not be liable for acting or refraining from acting upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper Party or Parties without inquiry and without requiring substantiating evidence of any kind. The Escrow Agent shall not be liable to any Party, any beneficiary or other person for refraining from acting upon any instruction setting forth, claiming, containing, objecting to, or related to the transfer or distribution of the Fund, or any portion thereof, unless such instruction shall have been delivered to the Escrow Agent in accordance with Section 11 below and the Escrow Agent has been able to satisfy any applicable security procedures as may be required thereunder.

The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through affiliates or agents. The Escrow Agent may consult with counsel, accountants and other skilled persons to be selected and retained by it. The Escrow Agent shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with, or in reliance upon, the advice or opinion of any such counsel, accountants or other skilled persons. In the event that the Escrow Agent shall be uncertain or believe there is some ambiguity as to its duties or rights hereunder or shall receive instructions, claims or demands from any Party hereto which, in its opinion, conflict with any of the provisions of this Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held in escrow until it shall be given a direction in writing by the Parties which eliminates such ambiguity or uncertainty to the satisfaction of Escrow Agent or by a final and non-appealable order or judgment of a court of competent jurisdiction. The Parties agree to pursue any redress or recourse in connection with any dispute without making the Escrow Agent a party to the same. Anything in this Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

Escrow Agent’s sole responsibility after such thirty (30) day notice period expires shall be to hold the Fund (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery Escrow Agent’s obligations hereunder shall cease and terminate, subject to the provisions of Section 8(b).

The indemnity obligations set forth in this Section 8(a) shall survive the resignation, replacement or removal of the Escrow Agent or the termination of this Agreement.

(b) The Parties hereby grant the Escrow Agent a lien on, right of set-off against and security interest in, the Fund for the payment of any claim for indemnification, fees, expenses and amounts due to the Escrow Agent or an Indemnitee. In furtherance of the foregoing, the Escrow Agent is expressly authorized and directed, but shall not be obligated, to charge against and withdraw from the Fund for its own account or for the account of an Indemnitee any amounts due to the Escrow Agent or to an Indemnitee under either Sections 6(a), 7 or 8(a) of this Agreement.

(a) Patriot Act Disclosure. Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the Escrow Agent to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Parties acknowledge that Section 326 of the USA PATRIOT Act and the Escrow Agent’s identity verification procedures require the Escrow Agent to obtain information which may be used to confirm the Parties identity including without limitation name, address and organizational documents (“identifying

information”). The Parties agree to provide the Escrow Agent with and consent to the Escrow Agent obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Escrow Agent.

Escrow Agent shall withhold any taxes it deems appropriate in the absence of proper tax documentation or as required by law, and shall remit such taxes to the appropriate authorities. The Parties hereby represent to the Escrow Agent that (i) there is no sale or transfer of an United States Real Property Interest as defined under IRC Section 897(c) in the underlying transaction giving rise to this Agreement; and (ii) such underlying transaction does not constitute an installment sale requiring tax reporting or withholding of imputed interest or original issue discount to the IRS or other taxing authority.

(b) The Parties acknowledge that the security procedures set forth in this Section 11are commercially reasonable.

12. Compliance with Court Orders.

13. Miscellaneous. Except for changes to funds transfer instructions as provided in Section 11, the provisions of this Agreement may be waived, altered, amended or supplemented, in whole or in part, only by a writing signed by the Escrow Agent and the Parties. Neither this Agreement nor any right or interest hereunder may be assigned in whole or in part by the Escrow Agent or any Party, except as provided in Section 6, without the prior consent of the Escrow Agent and the other Parties. This Agreement shall be governed by and construed under the laws of the State of New York. Each Party and the Escrow Agent irrevocably waives any objection on the grounds of venue, forum non-conveniens or any similar grounds and irrevocably consents to service of process by mail or in any other manner permitted by applicable law and consents to the jurisdiction of the courts located in the State of California.

The Escrow Agent and the Parties further hereby waive any right to a trial by jury with respect to any lawsuit or judicial proceeding arising or relating to this Agreement. No party to this Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, or other causes reasonably beyond its control. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. All signatures of the parties to this Agreement may be transmitted by facsimile, and such facsimile will, for all purposes, be deemed to be the original signature of such party whose signature it reproduces, and will be binding upon such party. If any provision of this Agreement is determined to be prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction. A person who is not a party to this Agreement shall have no right to enforce any term of this Agreement. The Parties represent, warrant and covenant that each

document, notice, instruction or request provided by such Party to Escrow Agent shall comply with applicable laws and regulations. Where, however, the conflicting provisions of any such applicable law may be waived, they are hereby irrevocably waived by the parties hereto to the fullest extent permitted by law, to the end that this Agreement shall be enforced as written. Except as expressly provided in Section 8 above, nothing in this Agreement, whether express or implied, shall be construed to give to any person or entity other than the Escrow Agent and the Parties any legal or equitable right, remedy, interest or claim under or in respect of this Agreement or any funds escrowed hereunder.

Payable upon closing and annually in advance thereafter, without pro-ration for partial years.

Extraordinary Services and Out-of Pocket Expenses

Any additional services beyond our standard services as specified above, and all reasonable out-of-pocket expenses including attorney’s or accountant’s fees and expenses will be considered extraordinary services for which related costs, transaction charges, and additional fees will be billed at the Bank’s then standard rate. Disbursements, receipts, investments or tax reporting exceeding 25 items per year may be treated as extraordinary services thereby incurring additional charges. The Escrow Agent may impose, charge, pass-through and modify fees and/or charges for any account established and services provided by the Escrow Agent, including but not limited to, transaction, maintenance, balance-deficiency, and service fees and other charges, including those levied by any governmental authority.

Disclosure & Assumptions

—

Please note that the fees quoted are based on a review of the transaction documents provided and an internal due diligence review. JPMorgan reserves the right to revise, modify, change and supplement the fees quoted herein if the assumptions underlying the activity in the account, level of balances, market volatility or conditions or other factors change from those used to set our fees.

—

The escrow deposit shall be continuously invested in a JPMorgan Chase Bank money market deposit account (“MMDA”) or a JPMorgan Chase Bank Cash Compensation account. MMDA and Cash Compensation Accounts have rates of compensation that may vary from time to time based upon market conditions. The Annual Administration Fee would include a supplemental charge up to 25 basis points on the escrow deposit amount if another investment option were to be chosen.

—

The Parties acknowledge and agree that they are permitted by U.S. law to make up to six (6) pre-authorized withdrawals or telephonic transfers from an MMDA per calendar month or statement cycle or similar period. If the MMDA can be accessed by checks, drafts, bills of exchange, notes and other financial instruments (“Items”), then no more than three (3) of these six (6) transfers may be made by an Item. The Escrow Agent is required by U.S. law to reserve the right to require at least seven (7) days notice prior to a withdrawal from a money market deposit account.

—	Payment of the invoice is due upon receipt.

Compliance

To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account. We may ask for information that will enable us to meet the requirements of the Act.

AMENDMENT NO. 1

ASSET PURCHASE AGREEMENT

THIS AMENDMENT NO. 1 TO ASSET PURCHASE AGREEMENT, dated as of September 23, 2011 (the “Effective Date”) is entered into by and between WORLD HEART CORPORATION, a Delaware corporation (“Seller”), and SYNCARDIA SYSTEMS, INC., a Delaware corporation (“Buyer”).

WHEREAS, Seller and Buyer previously entered into an Asset Purchase Agreement dated July 11, 2011 (the “Purchase Agreement”); and

WHEREAS, the Parties desire to amend the Purchase Agreement as set forth below.

NOW, THEREFORE, in consideration of the premises and mutual covenants, agreements and provisions herein contained, the parties hereto agree as follows:

1. Section 7.3 of the Purchase Agreement is hereby amended in its entirety as follows:

“7.3 Buyer Diligence Obligations.

(a) Buyer shall complete the installation of the Reactor at Buyer’s premises within forty-five (45) days of the Effective Date.

(b) Buyer shall produce the first batch of non-clinical grade SPUS within one hundred five (105) days of the Effective Date.

(c) Buyer shall produce the first batch of clinical grade SPUS within one hundred and thirty-five (135) days of the Effective Date.

such diligence event, then Seller may exercise its rights to terminate this Agreement, require the return of Purchased Assets and retain monies paid to Buyer by Seller through the date of termination in accordance with Article 9 below. For clarification, if Buyer makes payment to extend the time to meet a diligence commitment described in Section 7.3(a) or (b) for thirty (30) days as described above, thereafter the time in which Buyer is required to meet all subsequent diligence commitments shall automatically be extended by thirty (30) days without additional payment. For example, if Buyer is unable to produce the first batch of non-clinical grade SPUS within one hundred five (105) days of the Effective Date and makes the payment of sixty-two thousand five hundred dollars ($62,500.00) to extend the time to complete the installation of the Reactor to one hundred thirty five (135) days from the Effective Date, the time in which Buyer must produce the first batch of non-clinical grade SPUS shall thereafter be one hundred thirty-five (135) days from the Effective Date and the time in which Buyer must produce the first batch of clinical grade SPUS shall be one hundred sixty-five (165) days from the Effective Date. If, after the grant of the first thirty (30) day extension Buyer is not able to meet any of the revised diligence achievement dates and desires to extend such date by another thirty (30) days, the extension fee for the second request shall be Seventy-five Thousand Dollars ($75,000.00) and the fee for any additional extensions shall be One Hundred Thousand Dollars ($100,000.00). Seller has no obligation to grant Buyer more than one (1) extension per diligence obligation set forth above.”

2. All other terms of the Purchase Agreement remain in full force and effect.

3. Capitalized terms used herein, unless otherwise provided for, shall have the definition set forth in the Purchase Agreement for such terms.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment No. 1 to be executed by their respective duly authorized officers as of the date first above written.
