                          PRODUCTION SERVICES AGREEMENT

THIS AGREEMENT ("Agreement") is made and entered into as of the 17th day of
August, 2006, ("Effective Date") by and between HeartWare, Inc., a Delaware
corporation with its principal place of business at 3351 Executive Way, Miramar,
Florida 33025 ("Buyer"), and Minnetronix, Inc., a Minnesota corporation with its
principal place of business at 1635 Energy Park Drive, St. Paul, Minnesota 55108
("Seller").

WHEREAS, Seller is in the business of contract design and manufacturing of
electronic, software, and mechanical assemblies and has the capability to
manufacture Buyer's products described in Exhibit A ("Exhibit A") attached
hereto and made a part hereof (each a "Product" and collectively, "Products") as
well as to provide design, engineering, sustaining, manufacturing, test, and
support services related to such Products ("Services"); and

WHEREAS, Buyer is in the business of manufacturing, distributing and selling
medical devices and wishes to enter into a relationship during which Seller will
provide Products and Services to Buyer; and

WHEREAS, Buyer and Seller desire to establish the terms of sale for all Products
and Services now or hereafter purchased by Buyer from Seller during the term of
this Agreement;

NOW, THEREFORE, Buyer and Seller hereby agree as follows:

1.0 AGREEMENT SCOPE.

1.1 Application of Agreement. Buyer and Seller agree that all sales of Products
and Services from Seller to Buyer made during the term of this Agreement shall
be subject to the terms of this Agreement.

1.2 Products and Services. Each Product and additional required terms specific
to such Product is defined in Exhibit A, which sets forth a description thereof,
additional terms of sale and purchase, and unit pricing that shall apply thereto
("Price"). The parties may, from time to time, add new products by executing
addenda and/or amendments to Exhibit A. Services included in a Price, if any,
are described in the section entitled "Pricing" on Exhibit A.

1.3 Specifications. Complete specifications required to inspect, manufacture,
test, and ship the Products and the Components (as referenced in Section 4) in a
manner acceptable to Buyer, including part numbers, revisions, bills of material
and any other specifications applicable to Products ordered pursuant to this
Agreement ("Specifications") will be supplied by Buyer or Buyer's agent and
agreed upon in writing by Seller, or will be otherwise established and accepted
by Buyer and Seller via Seller's Engineering Change Order ("ECO") process and
documented in the Device Master Record ("DMR") and by part number. Seller and
Buyer have

                                                          CONFIDENTIAL TREATMENT

CONFIDENTIAL TREATMENT UNDER RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934.

EXCHANGE COMMISSION.

agreed upon the current Specifications for the Products, which are too complex
to attach as an exhibit hereto. Neither Seller nor the Product shall be expected
or required to perform outside of the Specifications, unless it is discovered
that such Specifications do not comply with the requirements of a regulatory
agency or board (including without limitation the U.S. Food and Drug
Administration), in which event Seller shall cooperate with Buyer at Buyer's
expense to change the Specifications in order to so comply.

1.4 Engineering Change Orders. Prior to Seller's making any "major revision"
(i.e., a change that may affect the form, fit or function of a Product) to a
Product assembly or sub-assembly (including, to the extent practicable, changes
incorporated by Seller's vendors, manufacturers and subcontractors
("Suppliers")), Seller will request Buyer's consent to such major revision by
issuing an ECO to Buyer. At a minimum, Buyer's approval of an ECO issued by
Seller with respect to the top level assembly of a Product will be required
prior to release of the Product to production. Notwithstanding any failure by
Buyer to specifically approve ECOs previously presented to Buyer by Seller,
Buyer's execution of an ECO shall be deemed to constitute Buyer's approval of
the revision subject to such ECO, together with all Components and
Specifications that are incorporated into the assembly or sub-assembly that is
the subject of such ECO. In no event will Seller ship any Products to Buyer that
incorporate Specifications that have not been approved by Buyer in accordance
with this Section 1.4, or that have been rendered obsolete by an ECO approved by
the parties in accordance with this Section 1.4. Seller will provide all
documentation reasonably requested by Buyer in connection with its review of any
ECO presented by Seller.

1.5 Inconsistencies in Documents. In the event of any inconsistency or conflict
between any of the documents described above and/or Purchase Orders (as defined
below in Section 3.1) issued pursuant to this Agreement, the following order of
priority, listed here from the highest priority (a) to the lowest priority (e),
in interpretation shall apply:

     (a)  Amendments or other modifications made to this Agreement.

     (b)  Exhibits of this Agreement.

     (c)  Product Specifications agreed to via Seller's ECO process.

     (d)  Purchase Order (exclusive of any terms and conditions attempting to
          amend this Agreement).

     (e)  This Agreement.

                                                REQUESTED PURSUANT TO RULE 24B-2

CERTAIN PORTIONS OF THIS EXHIBIT HAVE BEEN OMITTED PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT UNDER RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934.
THE OMITTED MATERIALS HAVE BEEN FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION.

2.1 Term. This Agreement shall commence upon its execution and shall continue
for an initial period of one year, and shall automatically renew for additional
periods of one year unless either party gives at least ninety (90) days of prior
written notice of its intention not to renew this Agreement or unless it is
terminated as provided herein.

2.2 Termination for Cause. In the event of a breach of a material term of this
Agreement by either party, the other party may, upon not less than sixty (60)
days' prior written notice to the party in breach, terminate this Agreement
unless the breach is cured prior to the end of the notice period, to the extent
susceptible of cure. Notwithstanding the foregoing, in the event that a party
has more than two (2) material breaches within a one hundred eighty (180) day
period, the other party may terminate this Agreement upon written notice to the
party in breach, with no right to a cure period for the party in breach. A
breach of a material term shall include, without limitation, the following:

     a)   Components and/or Products delivered to Buyer by Seller do not conform
          to the applicable Specification at the time of such delivery, and
          Seller does not operate in good faith to reasonably cure such
          non-conformance in a timely manner;

     b)   Buyer fails to make payment to Seller for Products on a timely basis;

     c)   Buyer fails to receive Products according to the agreed upon delivery
          schedule; or

     d)   Seller fails to make deliveries of Products on a timely basis in
          accordance with Section 3.4 other than as a result of a Force Majeure
          Event, as defined in Section 11.9 hereof.

Notwithstanding the foregoing, if Seller or Buyer ceases to conduct its
operations in the normal course of business (including an inability to meet its
obligations as they mature), or if any proceeding under the bankruptcy or
insolvency laws are brought by or against Seller or Buyer (and not dismissed
within 60 days) or if a receiver is appointed to or applied for by Seller or
Buyer, the other party may terminate this Agreement and/or any Purchase Orders
upon such event without liability, except for deliveries previously made or for
Products ordered and covered by this Agreement that are completed or in process
at the time of termination and subsequently delivered in accordance with the
terms of this Agreement.

2.3 Buyer's Termination for Convenience. During any renewal term of this
Agreement, Buyer may, upon at least one hundred eighty (180) days' prior written
notice to Seller, terminate this Agreement for Buyer's convenience; provided
that such termination shall not affect any outstanding Purchase Orders.

2.4 Seller's Termination for Convenience. Seller may discontinue supply of any
Product under this Agreement by giving Buyer prior written notice one hundred
eighty (180) days in

advance of said discontinuation, provided that Buyer shall have the option to
purchase up to a "Lifetime" supply of the Product at the then-current Product
revision level for delivery within such one hundred eighty (180) day period.

2.5 Effects of Termination. Upon termination of this Agreement, Sections 2, 5.3,
5.6, 5.7, 5.8, 8 (as it relates to payments due but not yet paid as of the date
of termination), 9, 10, and 11 shall survive in accordance with their provision.
A party's right to terminate this Agreement shall be without prejudice to any
other remedies available to such party at law or in equity. In the event of
notification of termination of the Agreement, Buyer's and Seller's obligations
under this Agreement shall continue without interruption through the date of
termination.

3.0 ORDERS, DELIVERY, AND ACCEPTANCE.

3.1 Purchase Orders. Buyer's purchase orders issued to Seller will be properly
authorized, written, emailed, or facsimile documents specifying, and/or
attaching items including: Products, Components, description, applicable part
numbers, quantity, revision, delivery schedule, destination, shipping method,
Specifications, special acceptance criteria (if any), unit price, and total
authorized cost of the order ("Purchase Order"). The parties shall agree in
writing on each Purchase Order, and the Specifications referenced thereon (using
Seller's part numbers), prior to the commencement of any work related to such
Purchase Order, after which Seller shall manufacture for Buyer the Products
identified in such Purchase Order.

Commencement of work related to this Agreement or related to Purchase Orders is
done so under the terms of this Agreement. Any additional or different terms
from Buyer sent together with Purchase Orders or otherwise sent to Seller or
from Seller to Buyer shall be excluded unless signed by both parties as an
Amendment or an Exhibit to this Agreement.

3.2 Packaging. Seller shall prepare and pack Products in accordance with the
Specifications. Costs for preparation and Product packaging are included in the
Price unless not specified as part of the Product part number ordered by Buyer.
Costs for crating, palletizing, and/or bulk packaging are not included in the
Price.

3.3 Shipping. Shipping terms are FOB Seller's facility. Seller shall select
freight carrier of its choosing unless otherwise specified by Buyer in a
Purchase Order.

3.4 Delivery. The Purchase Order shall specify requested delivery dates. Seller
shall ship products with appropriate lead-time such that Products arrive at
Buyer's dock on or reasonably around the requested arrival dates (absent a Force
Majeure Event); provided, that Seller shall notify Buyer if it has reason to
believe that any particular shipment of Products may not arrive at Buyer's dock
within ten (10) days after the requested arrival dates, it being agreed and
understood by the parties that the failure by Seller, on more than three (3)
occasions with respect to any five (5) consecutive required delivery dates as
set forth in Purchase Orders previously

delivered by Buyer and agreed upon by Seller, to deliver all units required to
be delivered pursuant to such Purchase Orders upon any particular delivery date
to Buyer's dock within the ten-day period following the respective delivery date
(provided the cause of such delivery failure is not attributable to a request by
Buyer that Seller make modifications to one or more Products prior to delivery
that would not otherwise have had to been made by Seller in order to deliver
Products in accordance with a then-effective Purchase Order) may result in Buyer
terminating this Agreement under Section 2.2.

3.5 Acceptance. The acceptance criteria for each Product shall be "conformance
to the Specifications at the time of delivery." In the event that there are
additional acceptance criteria by Buyer, they must be specified on the Purchase
Order at the time of the initial order in accordance with Section 3.1.

     3.5.1 Within ten (10) business days of Buyer's receipt of Product, Buyer
     shall notify Seller in writing of any rejected Product and listing therein
     any and all Specifications which remained unmet at the time of delivery.
     Buyer bears the risk of loss and expense due to unnecessary return of
     Product that was in fact conforming to the Specifications at the time of
     delivery as verified by Seller through the testing and inspection
     procedures defined in the Device Master Record for such Product or
     otherwise established and agreed to by Buyer via Seller's ECO system. See
     additionally Section 6.0 below. In the event Product is returned to Seller
     that was conforming at the time of delivery, additional expense of Buyer
     includes the reasonable expense incurred by Seller in investigating the
     purported defect or damage.

     3.5.2 Upon return of non-conforming Product, Seller will as soon as
     reasonably practical (at its own option) either repair, replace or credit
     Buyer for non-conforming Product. The cost associated with any such repair,
     replacement or credit will be the responsibility of Seller. In the case of
     replacement or credit, title to the non-conforming Products shall pass to
     Seller on return delivery to Seller's dock and Seller's receipt of returned
     Product.

     3.5.3 In the absence of earlier notification of rejection, Buyer will be
     deemed to have accepted Products ten (10) business days after Buyer's
     receipt of the Product. Buyer payments for Product after approval or
     acceptance of any Products shall not (a) relieve Seller from responsibility
     to deliver Products in conformance with the Specifications, or (b) waive
     any warranty rights of Buyer hereunder.

4.0 COMPONENTS AND CONFIGURATION MANAGEMENT.

4.1 Configuration Control. Seller will maintain source control on all parts,
materials, subassemblies, and components used in connection with the manufacture
of Products in accordance with the provisions of Section 5.1 hereof
("Components"), unless otherwise

EXCHANGE COMMISSION.

specified. Buyer will have access to bill of material ("BOM") data, including
without limitation the cost associated with the subcomponents and subassemblies,
inventory status, and production status as reasonably requested.

4.2 Product Revisions. Seller uses a product revision format that indicates
different levels of product release. All revisions have a format of [major
revision]-[minor revision]. Major revisions (i.e., changes that may affect the
form, fit or function of any Product) are less than "1" (e.g., .01, .02, .5,
etc.) prior to production release and are "001" or greater (e.g., 001, 002,
etc.) after production release. Minor revisions start with alpha characters
beginning at "a" after each major revision change and are incremented for each
minor revision change (e.g., a, b, c, etc.). All Products provided at a revision
less than 001-a (e.g., .01-a, .01-b, .5-a, etc.) shall be considered prototypes
or pre-production units ("Engineering Units"). All Products provided at a
revision level of 001-a or higher (e.g., 001-a, 001-b, 002-a, etc.) shall be
considered production units ("Production Units").

4.3 Component Scheduling. Seller shall maintain scheduling control over
Components ordering and their delivery scheduling according to Seller's
production scheduling processes. Seller will issue purchase orders, or otherwise
place orders, for all Components to support Buyer's Purchase Orders throughout
the term of the Agreement. Any scheduling outside of Seller's standard processes
shall require Buyer's prior written approval. Seller will commit to longer-term
buys on an exception basis as reasonably requested by Buyer provided that all
such requests are issued in writing to Seller by Buyer.

4.4 Components and other Parts Purchases. Seller agrees to sell sub-assemblies,
Components, and other parts, from its inventory to Buyer on a "cost plus" basis,
upon Buyer's reasonable request. Seller will quote a price, including any
minimum quantity, to Buyer for such Components upon request by Buyer. All such
sales are subject to the terms of this Agreement. For purposes of this section
only (Section 4.4), the term "cost plus" shall mean Seller's actual cost in
manufacturing or purchasing such sub-assemblies, Components and other parts,
plus 25% of such actual cost. See Section 8.7 below which defines Seller's
"actual cost."

4.5 Product Orders. Forecasts and Schedule Changes. Buyer will provide Purchase
Order(s) representing a firm commitment for Products to be delivered as
specified on the Purchase Order. In addition, Buyer shall provide non-binding
forecasts to Seller ("Forecasts"), which Forecasts reflect Buyer's expected
Product(s) volume requirements over a 12 month period. Seller will make
reasonable efforts to accommodate schedule change requests, subject to Component
availability and capacity, at Seller's sole reasonable discretion. Aggressive
schedule increases will be accommodated to the best of Seller's ability
according to the terms of this Agreement. Seller may use the Forecasts to
purchase long lead-time items and to achieve price breaks due to order size.
Forecasts and Purchase Orders may be combined to make best effort purchasing
decisions. Excess or scrap Components that occur as a result of Seller's best
effort purchasing

decisions, pursuant to Purchase Orders only, are Buyer's responsibility in the
event of an order cancellation, Product change, or production delay.

4.6 Disaster Recovery Plan. Seller represents and warrants to Buyer that it has
in place a disaster recovery plan consistent with industry standards that
describes the resources, actions, tasks and data required to manage Seller's
business recovery process in the event of a business interruption (the "Plan"),
including without limitation a significant or catastrophic event adversely
affecting in any material respect Seller's ability to supply Products. At all
times during the term of this Agreement, Seller shall maintain such Plan, or a
similar plan that has at least the protections contained in the Plan, in full
force and effect.

5.0 QUALITY SYSTEMS, REGULATORY, AND AGENCIES.

5.1 Quality Systems Requirements. Seller will establish and maintain formal
quality systems and processes that are compliant with the FDA's Quality System
Regulation ("QSR") and ISO 13485, and shall use its commercially reasonable
efforts to ensure that all of Seller's Suppliers are compliant therewith to the
extent that compliance by such Suppliers is required thereunder. Such systems
and processes will be provided and maintained at all times during the term of
this Agreement by Seller and, to the extent reasonably practicable, all
Suppliers to the extent required under the QSR and/or ISO 13485. Any and all
special quality system requirements for the Products shall be provided by or
agreed to by Buyer via the Specifications for the Product or as subsequently
changed via Seller's ECO processes, in writing, at the time of Purchase Order.
Seller will inform Buyer and obtain prior approval in accordance with Seller's
ECO process, as described under Section 1.4, for any changes to be made,
including changes with respect to Seller's Suppliers, that can affect the form,
fit or function of the Products.

5.2 Buyer Audit Rights. Seller agrees that Buyer or any of its duly authorized
representatives shall have access to and the right to reasonably perform routine
audits on any pertinent design, manufacturing, or quality systems, and
associated documentation, provided that Buyer shall provide Seller with five (5)
business days' prior written notification and require two (2) business days or
less to complete. Such audits shall occur at most once every six (6) month
period, provided that, in the event Buyer discovers a major non-conformance,
there shall not be any continuing limitation on the number of audits that Buyer
may undertake, provided that such additional audits are requested by Buyer in
good faith and Buyer clearly identifies in writing to Seller its reasons for
conducting such additional audit and the proposed scope of such audit. In the
event Buyer discovers a major non-conformance that is attributable to one of
Seller's Suppliers, Seller shall use its commercially reasonable efforts to
obtain such Supplier's consent to affording Buyer access to such Supplier's
facility so that Buyer may review such major non-conformance. Buyer and Seller
shall each incur all of its own costs in connection with routine audits.

     If, as a result of any of the aforesaid audits, Buyer becomes aware that
the production, packaging and/or quality systems and processes of Seller would
result in a major non-conformance, Buyer shall promptly notify Seller about such
non-conformance and Seller herewith undertakes to rectify all major
non-conformances in production, packaging or quality systems and processes.
Without limiting the generality of the foregoing, in the event that the major
non-conformance relates to the quality systems or processes of Seller, Buyer
shall be entitled to conduct a source inspection in order to determine the
specific issues relating to the major non-conformance.

          that may be copyrightable, patentable or trade secret material. Buyer
          hereby grants to Seller a non-exclusive, perpetual, fully-paid up,
          royalty free, worldwide, irrevocable right and license, with the right
          to grant sublicenses, to all Developed Materials that are not Buyer
          Materials, to make, have made, use, reproduce, modify, make derivative
          works, make improvements, publicly display, distribute, sell (either
          directly or indirectly), and offer to sell (either directly or
          indirectly), lease, import, practice and otherwise transfer or dispose
          of such item as part of or in connection with such Developed Materials
          that are not Buyer Materials. Each party shall use commercially
          reasonable efforts to notify the other party in writing within 90 days
          of receipt or notice thereof of any Developed Materials that it
          considers to be patentable or for which a copyright registration
          should be sought or that it considers to be a trade secret and, if
          applicable or appropriate in Buyer's reasonable commercial judgment,
          to cooperate in the preparation of a patent review plan at Buyer's
          expense. Notwithstanding the foregoing, any failure to deliver such a
          notice within such 90-day period shall not affect in any way Buyer's
          ownership of and property rights in any Developed Materials; provided
          that, in the event that Seller or a third party makes use of any such
          Developed Materials after the 90-day period, but prior to receipt of a
          notice from Buyer provided for above, any such Developed Materials
          that would have been Buyer Materials if proper notice had been given
          shall be deemed to be Developed Materials (and not Buyer Materials)
          and shall be subject to the rights granted to Seller pursuant to the
          terms of this Section 9.3. Whenever requested to do so by Buyer,
          Seller shall execute any and all applications, assignments, oaths or
          other instruments and give testimony which Buyer shall deem necessary
          to apply for and obtain letters of patent of the United States or of
          any foreign country or to protect otherwise Buyer's interest therein.
          Seller further agrees that Seller's obligation to execute or cause to
          be executed, when it is in Seller's power to do so, any such
          instrument or papers shall continue after the termination of this
          Agreement.

     (b)  Seller agrees that if Buyer is unable because of Seller's
          unavailability or unwillingness after 10 business days prior written
          notice, or dissolution, to secure Seller's signature, which will not
          be unreasonably withheld, to apply for or to pursue any application
          for any United States or foreign patents or mask work or copyright
          registrations covering the Developed Materials assigned to Buyer
          above, then Seller hereby irrevocably designates and appoints Buyer
          and its duly authorized officers and agents as Seller's agent and
          attorney in fact, to act for and in Seller's behalf and stead to
          execute and file any such applications and to do all other lawfully
          permitted acts to further the prosecution and issuance of patents,
          copyright and mask work registrations thereon with the same legal

          that Seller shall obtain the right, and shall grant to Buyer, or shall
          obtain on Buyer's behalf, a non-exclusive, perpetual, worldwide,
          royalty-free license to all such Supplier Materials that may be

          Products, and all related design information and documentation.

9.4 Seller's Inability to Deliver. In the event that Seller can no longer

otherwise ceasing to conduct its operations, Seller shall provide Buyer with
exclusive, perpetual, irrevocable, worldwide, royalty-free license rights in the
Field to any intellectual property owned by Seller necessary for the production
of the Products. Seller shall provide to Buyer all information, designs, and

transferred in whole or in part by operation of law or otherwise without the
other party's prior express written consent, which shall not be unreasonably
withheld, conditioned, or delayed, provided that Buyer may assign its rights

11.19 Dispute Resolution.

          (a) Senior Executives. Controversies between Buyer and Seller shall be
     resolved, to the extent possible, by informal meetings and discussions in
     good faith between the parties. If a controversy cannot be resolved by
     informal meetings and discussions within five days after commencement
     thereof, the dispute shall be referred to senior executives of the parties
     ("Senior Executives"), who shall work together in good faith to resolve the
     dispute. The initial Senior Executives shall be Dozier Rowe on behalf of
     Buyer and Jonathan D. Pierce on behalf of Seller.

          (b) Arbitration. If the parties are unable to resolve a controversy
     pursuant to Section 11.19(a) within fifteen (15) days after commencement
     thereof, the dispute shall be settled binding arbitration in accordance
     with the Commercial Arbitration Rules of the American Arbitration
     Association ("AAA"), and the procedures set forth below. In the event of
     any inconsistency between the Rules of AAA and the procedures set forth
     below, the procedures set forth below shall control. Judgment upon the
     award rendered by the arbitrators may be enforced in any court having
     jurisdiction thereof.

          (d) Location. The location of the arbitration shall be in Chicago,
     Illinois.

          (e) Selection of Arbitrators. The arbitration shall be conducted by a
     panel of three neutral arbitrators who are independent and disinterested
     with respect to the parties, this Agreement, and the outcome of the
     arbitration. Each party shall appoint one neutral arbitrator, and these two
     arbitrators so selected by the parties shall then select the third
     arbitrator. If one party has given written notice to the other party as to
     the identity of the arbitrator appointed by the party, and the party
     thereafter makes a written demand on the other party to appoint its
     designated arbitrator within the next ten days, and the other party fails
     to appoint its designated arbitrator within ten days after receiving said
     written demand, then the arbitrator who has already been designated shall
     appoint the other two arbitrators.

          (e) Discovery. Unless the parties mutually agree in writing to some
     additional and specific pre-hearing discovery, the only pre-hearing
     discovery shall be (a) reasonably limited production of relevant documents,
     and (b) the identification of witnesses to be called at the hearing, which
     identification shall give the witness's name, general qualifications and
     position, and a brief statement as to the general scope of the testimony to
     be given by the witness. The arbitrators shall decide any disputes and
     shall control the process concerning these pre-hearing discovery matters.
     Pursuant to the Rules of AAA, the parties may subpoena witnesses and
     documents for presentation at the hearing. Notwithstanding anything to the
     contrary contained in the foregoing, in no event shall discovery extend
     past thirty (30) days.

          (f) Case Management. Prompt resolution of any dispute is important to
     both parties; and the parties agree that the arbitration of any dispute
     shall be conducted expeditiously. The arbitrators are instructed and
     directed to assume case management initiative and control over the
     arbitration process (including scheduling of events, pre-hearing discovery
     and activities, and the conduct of the hearing), in order to complete the
     arbitration as expeditiously as is reasonably practical for obtaining a
     just resolution of the dispute, provided that in no event may the entire
     arbitration process extend past sixty (60) days.

          (g) Remedies. The arbitrators may grant any legal or equitable remedy
     or relief that the arbitrators deem just and equitable, to the same extent
     that remedies or relief could be granted by a state or federal court,
     provided however, that no punitive damages may be awarded. No action may be
     maintained seeking punitive damages. The decision of any two of the three
     arbitrators appointed shall be binding upon the parties.

          (h) Expenses. The expenses of the arbitration, including the
     arbitrators' fees, expert witness fees, and attorney's fees, may be awarded
     to the prevailing party, in the discretion of the arbitrators, or may be
     apportioned between the parties in any manner deemed appropriate by the
     arbitrators. Unless and until the arbitrators decide that one party is to
     pay for all (or a share) of such expenses, both parties shall share equally
     in the payment of the arbitrators' fees as and when billed by the
     arbitrators.

11.20 Binding Agreement. Execution of this document shall create a binding
Agreement and constitutes a commitment on the part of Buyer to pay for all
Products delivered hereunder according to the purchase price or rate structure
stated in the Agreement, Product or Service Addenda (Exhibits), or Amendments.

                                    EXHIBIT A

                            HEARTWARE LVAD COMPONENTS
                                PRODUCT ADDENDUM

This Product Addendum on Exhibit A shall be effective as of August 17, 2006
("Effective Date") and shall be attached to and considered a part of the
Minnetronix Production Services Agreement ("Agreement") dated as of August 17,
2006 by and between HeartWare, Inc. ("Buyer") and Minnetronix, Inc. ("Seller").
Capitalized terms used but not otherwise defined in this Exhibit A shall have
the meanings ascribed to such terms in the Agreement.

     A.1. Product Description. Buyer intends to purchase from Seller various
     components to be used in clinical testing of its Left Ventricular Assist
     Device (LVAD) System (each such component being referred to herein as a
     "Product" and collectively, "Products"). All Products initially will be in
     "interim release," as defined in Seller's Engineering Changes SOP, document
     # DQ-0000-13-0, revision 007-a, and described in the Pioneer System
     Development Plan, Seller's document # DP-0001-46-9, revision .02-a. A list
     of Products is included under A.2 below.

     A.2. Pricing. The applicable price for each Product in effect from time to
     time ("Price") shall be determined in accordance with the terms and
     conditions set forth in the Agreement and this Exhibit A. The initial
     Product Price schedule shall be as shown in the table below. The initial
     Product Price schedule is based on the minimum number of units of each
     Product expected to be ordered by Buyer and delivered by Seller between
     the Effective Date and June 30, 2007 ("Initial Pricing Period"), which
     minimum order volumes are set forth in the table below. Any Products
     ordered by Buyer on or before September 1, 2006 for delivery by Seller
     during the Initial Pricing Period, provided the minimum order volume
     requirements set forth below are met, will be sold at the initial Prices
     set forth below; provided, however, that, notwithstanding the foregoing,
     the initial Price for each Product is subject to change during the Initial
     Pricing Period if the Agreement, Specifications, Components, Products,
     Services, Exhibit, order quantity or delivery period with respect to such
     Product is changed in a manner that impacts the initial Product Price,
     either as to increase or decrease; provided, however, that any such change
     arising from the actions or inactions of Seller in material breach of its
     obligations under the Agreement shall not trigger any price increase
     hereunder. Each Purchase Order for any Product must specify Seller's part
     and revision numbers for such Product.

*     Note: The Price for this Product does not reflect any amounts for
      hazardous material shipping requirements, as this Product currently does
      not have a regulatory exemption. Therefore, an additional amount will be
      charged by Seller to cover its actual costs incurred in compliance with
      all applicable hazardous material shipping requirements to the extent an
      exemption from such requirements is not obtained; provided that Seller
      notifies Buyer in advance of any such charge. Seller shall cooperate with
      Buyer, at Buyer's expense, to obtain any necessary regulatory exemption to
      the extent requested by Buyer.

Buyer and Seller have worked in good faith to support device needs prior to
execution of the Agreement and this Exhibit A. This has resulted in some units
to be built in quantities different than the quantities shown in the table
above. The Products and quantities set forth in the attachment to the email
dated July 19, 2006 from Jonathan Pierce to Dozier Rowe summarizing Product
status as of July 18, 2006 (as set forth in Column G in such e-mail attachment),
shall be converted into a Purchase Order (the "Initial Purchase Order") to be
placed by Buyer, at the Prices set forth in the above table, separate from, and
prior to placing, a Purchase Order under the Agreement and this Exhibit A for
the minimum order quantities shown above. All terms and conditions set forth in
the Agreement and this Exhibit A shall apply to the Initial Purchase Order,
except that the minimum order volumes set forth in the above table will not
apply, and the Initial Purchase Order will also include an additional charge
payable to Seller in the amount of $20,250.

For Products to be ordered by Buyer for delivery following expiration of the
Initial Pricing Period, the Price shall be determined via a Seller's Price
quotation and corresponding placement of a Purchase Order by Buyer accepting
such Price. The Price shall be quoted and agreed to from time to time based on a
quantity and delivery schedule as requested by Buyer and stated on Purchase
Order(s) placed by Buyer. Subsequent to placement of such Purchase Order(s), it
is subject to change if the Agreement, Specifications, Components, Products,
Services, Exhibit, order quantity or delivery period are changed in a manner
that impacts such Price, either as to increase or decrease; provided, however,
that any such change arising from the actions or inactions of Seller in material
breach of its obligations under the Agreement shall not trigger any Price
increase hereunder. In addition, Prices may change as a result of increases or
decreases in the prices charged by Seller's suppliers or as manufacturing
efficiencies are developed (see Section 8.8 of the Agreement regarding cost
reduction efforts). The Price for any Product provided by Seller shall be valid
for ninety (90) days after the date the quote is made.

     A.3. Downpayment. A downpayment equal to 20% of the value (i.e., Price
     times number of units) of each order of Products shall be paid by Buyer at
     the time of placement of a Purchase Order. The downpayment is intended to
     share the materials and schedule risk that is taken on by both parties once
     a Purchase Order is placed for Products. As invoices are issued by Seller
     to Buyer with respect to shipped Products, a pro rata credit per shipped
     unit will be reflected on such invoices to account for the downpayment.

     A.4. Delivery Schedule. The delivery schedule for Product orders will be as
     stated on Purchase Orders placed by Buyer, based on quantity and delivery
     terms included in Seller's Price quote, and agreed upon by Seller.

     A.5. Testing. The Product functional and quality control testing to be
     performed to verify the Products' conformance to the Specifications at the
     time of delivery will be as per the testing and inspection procedures
     defined in the Device Master Record ("DMR") or otherwise established and
     agreed to by Buyer via Seller's Engineering Change Order ("ECO") process.

     A.6. Packaging. The Product packaging will be as currently specified in the
     DMR or otherwise established and agreed to by Buyer via Seller's ECO
     process.

     in a manner consistent with FDA Class III/MDD Class III requirements, as
     currently specified in the DMR or otherwise established and agreed to by
     Buyer via Seller's ECO process.

     A.13. Certificate of Conformance. Each shipment of Products at "interim
     release" or above will be accompanied by a certificate of conformance
     signed by a duly authorized representative of Seller certifying that, for
     those Products covered by the warranty provisions set forth in Section 10.4
     of the Agreement, the shipped Production Units and/or Engineering Units
     meet the warranty requirements set forth in Section 10.4 of the Agreement.
     In addition, the certificate of conformance shall expressly identify by
     serial number those Engineering Units and/or Production Units, if any, that
     are not intended for human use and Seller shall affix a "not for human use"
     label to such units prior to shipment.

     A.14. Units Suitable for Human Use. Each Engineering Unit that (a) has been
     manufactured by Seller for Buyer pursuant to a Purchase Order delivered
     hereunder for Products, (b) represents an "interim release" Product as
     described in A.1 above (i.e., is at
