San Diego, California





        FOR VALUE RECEIVED, CARDIONET, INC., a California corporation (the
"Company"), hereby promises to pay to the order of                        
(the "Purchaser"), the principal sum
of $                        , together with accrued and unpaid interest thereon, each due and payable on the date and in the
manner set forth below. 


        This
note is one of a series of similar notes being issued of even date herewith in the aggregate principal amount of
$                        . The Company has also issued a series of notes
pursuant to the Note and Warrant Purchase Agreement dated May 1, 2006 among the Company and the Purchasers listed on the Schedule of Purchasers attached thereto (the  "Purchase Agreement").
Collectively, the notes issued of even date herewith and the notes issued pursuant to the Purchase Agreement are referred to
herein as "Notes" and each individually as a "Note". All Notes rank in parity with each other Note. This
Note is one of the Notes referred to in and is executed and delivered in connection with that certain Amended and Restated Security Agreement dated as of even date herewith and executed by Company in
favor of the Secured Parties set forth therein (as the same may from time to time be amended, modified or supplemented or restated, the "Security
Agreement"). Additional rights of the Purchaser are set forth in the Security Agreement. 


1.    Maturity Date.    On the first to occur of (i) a sale, lease or other
disposition of all or substantially all of the assets of the Company (an "Asset Transfer"), (ii) (A) any consolidation or merger of the
Company with or into any other corporation or other entity or person in which the shareholders of the Company immediately prior to such consolidation or merger, own less than 50% of the voting power
of the surviving entity immediately after such consolidation or merger or (B) any transaction or series of transactions to which the Company is a party in which in excess of 50% of the
Company's voting power is transferred (an "Acquisition" and, together with an Asset Transfer, a "Disposition
Transaction"), provided that an Acquisition shall not include (x) any consolidation or merger effected exclusively to change the domicile of the Company or
(y) any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the Company or any successor or indebtedness of the Company is
cancelled or converted or a combination thereof, or (iii) February 15, 2007 or such later date as may be determined by the written consent of the holders of at least 67% of the aggregate
principal amount of all Notes (the "Majority Lenders") (the first to occur, the "Maturity Date"), the
entire outstanding principal balance and all unpaid accrued interest hereof shall become fully due and payable to the Purchaser. 


2.    Interest.    Interest shall accrue on the outstanding principal amount hereof
from the date of this Note
until payment or conversion in full, which interest shall be payable at the rate of 8% per annum or the maximum rate permissible by law (which under the laws of the State of California shall be deemed
to be the laws relating to permissible rates of interest on commercial loans), whichever is less. Interest shall be due and payable on the Maturity Date, and shall be calculated on the basis of a
365-day year for the actual number of days elapsed. 







 



3.    Payment.    Unless the indebtedness outstanding under this Note is converted
in accordance with Section 5 hereof, payment shall be made in lawful money of the United States to the Purchaser at the Company's principal offices or, at the option of the Purchaser, at such
other place in the United States as Purchaser shall have designated by written notice to the Company. All payments shall be applied first to accrued interest and thereafter to principal and shall be
made pro rata to all holders of Notes. 


4.    Prepayment.    Subject to Section 3 above, the Company may prepay all
or any part of the principal or accrued interest outstanding under this Note at any time other than at such time as the Company is negotiating or otherwise expecting to enter into a Disposition
Transaction with a specific third party. 


5.    Conversion    


        5.1    Optional Conversion at Next Equity Financing.    Upon the
closing of the Next Equity Financing (as defined below) on or prior to the Maturity Date, the Majority Lenders may, upon prior written notice to the Company, elect to convert all unpaid principal and
accrued interest outstanding under this Note (the "Conversion Amount") as of the date thereof into that number of shares of the Preferred Stock sold by
the Company in the Next Equity Financing as is equal to the Conversion Amount divided by the per share purchase price of the Preferred Stock sold in the Next Equity Financing and on the other terms
and conditions provided to purchasers in the Next Equity Financing. "Next Equity Financing" shall mean the first equity financing following the date
hereof involving the sale by the Company of its Preferred Stock in which the Company receives an aggregate of at least $8,000,000 in cumulative gross proceeds, including conversion of the Notes and
interest hereon and thereon and the conversion of all other indebtedness of the Company. 



        5.2    Optional Conversion at Disposition Transaction.    Immediately
prior to the closing of a Disposition Transaction, the Purchaser may, upon 10 days' prior written notice to the Company, elect to convert the Conversion Amount as of the date thereof into that
number of shares of Series D-1 Preferred (as defined in the warrant issued to the holder of even date herewith (the "Warrant")) as is
equal to the Conversion Amount divided by $3.50 (as adjusted for stock dividends, combinations, splits and other recapitalizations after the date hereof). 



6.    Termination of Rights.    All rights with respect to this Note shall terminate
upon a payment or conversion of the Conversion Amount in full, whether or not this Note has been surrendered. 


7.    Secured Note.    The full amount of this Note is secured by the Collateral
identified and described as security therefor in the Security Agreement. 



8.    Default.    Each of the following events shall be an
"Event of Default" hereunder: 



        (a)   The Company commits a material breach of the representations, warranties or covenants in the Purchase Agreement; 


        (b)   The Company files a petition or action for relief under any bankruptcy, insolvency or moratorium law or any other law for
the relief of, or relating to, debtors, now or hereafter in effect, or makes any assignment for the benefit of creditors or takes any action in furtherance of any of the foregoing; 



        (c)   An involuntary petition is filed against the Company (unless such petition is dismissed or discharged within
60 days) under any bankruptcy statute now or hereafter in effect, or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is appointed to take
possession, custody or control of any property of the Company; 


        (d)   An "Event of Default" under the Security Agreement; or 


        (e)   The Company defaults in the payment of principal when due at stated maturity of other indebtedness for borrowed money or
acceleration of such other indebtedness for borrowed money where the aggregate principal amount with respect to which the default or acceleration has

        Upon
the occurrence of an Event of Default, all unpaid principal, accrued interest and other amounts owing hereunder shall, at the option of the Majority Lenders, and, in the case of an
Event of Default pursuant to (b) or (c) above, automatically, be immediately due, payable and
collectible by the Purchaser pursuant to applicable law. Subject to the provisions hereof, the Purchaser shall have all rights and may exercise any remedies available to it under law, successively or
concurrently. 


9.    Subordination.    The indebtedness evidenced by this Note is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of the Senior Indebtedness.

of, unpaid interest on and amounts reimbursable, fees, expenses, costs of enforcement and other amounts due in connection with (a) indebtedness of the Company secured by (A) the Security

additional secured indebtedness of the Company to Guidant or Guidant's affiliates, Varian, Montgomery County or Silicon Valley Bank. 


        9.1    Insolvency Proceedings.    If there shall occur any
receivership, insolvency, assignment for the benefit of creditors, bankruptcy, reorganization, or arrangements with creditors (whether or not pursuant to bankruptcy or other insolvency laws), sale of
all or substantially all of the assets, dissolution, liquidation, or any other marshaling of the assets and liabilities of the Company, (a) no amount shall be paid by the Company in respect of
the principal of, interest on or other amounts due with respect to this Note at the time outstanding, unless and until the principal of and interest on the Senior Indebtedness then outstanding shall
be paid in full, and (b) no claim or proof of claim shall be filed by or on behalf of the Purchaser which shall assert any right to receive any payments in respect of the principal of and
interest on this Note except subject to the payment in full of the principal of and interest on all of the Senior Indebtedness then outstanding. 



        9.2    Default on Senior Indebtedness.    If there shall occur an
event of default which has been declared in writing with respect to any Senior Indebtedness, as defined therein, or in the instrument under which it is outstanding, permitting the holder to accelerate
the maturity thereof and the Purchaser shall have received written notice thereof from the holder of such Senior Indebtedness, then, unless and until such event of default shall have been cured or
waived or shall have ceased to exist, or all Senior Indebtedness shall have been paid in full, no payment shall be made in respect of the principal of or interest on this Note unless within
180 days after the happening of such event of default the maturity of such Senior Indebtedness shall not have been accelerated. Not more than one notice may be given to the Purchaser pursuant
to the terms of this Section 9.2 during any 360 day period. 


        9.3    Further Assurances.    By acceptance of this Note the Purchaser
agrees to execute and deliver customary forms of subordination agreement requested from time to time by the holders of Senior Indebtedness and, as a condition to the Purchaser's rights hereunder, the
Company may require that the Purchaser execute such forms of subordination agreement, provided that such forms shall not impose on the Purchaser terms less favorable than those provided herein.

        9.4    Subrogation.    Subject to the payment in full of all Senior
Indebtedness, the Purchaser shall be subrogated to the rights of the holder(s) of such Senior Indebtedness (to the extent of the payments or distributions made to the holder(s) of such Senior
Indebtedness pursuant to the provisions of this Section 9) to receive payments and distributions of assets of the Company applicable to the Senior Indebtedness. No such payments or
distributions applicable to the Senior Indebtedness shall, as between the Company and its creditors, other than the holders of Senior Indebtedness and the Purchaser, be deemed to be a payment by the
Company to or on account of this Note; and for purposes of such subrogation, no payments or distributions to the holders of Senior Indebtedness to which the Purchaser would be entitled except for the
provisions of this Section 9 shall, as between the Company and its creditors, other than the holders of Senior Indebtedness and the Purchaser, be deemed to be a payment by the Company to or on
account of the Senior Indebtedness. 


        9.5    No Impairment.    Subject to the rights, if any, of the holders
of Senior Indebtedness under this Section 9 to receive cash, securities or other properties otherwise payable or deliverable to the Purchaser, nothing contained in this Section 9 shall
impair, as between the Company and the Purchaser, the obligation of the Company, subject to the terms and conditions hereof, to pay to the Purchaser the principal hereof and interest hereon as and
when the same become due and payable, or shall prevent the Purchaser, upon default hereunder, from exercising all rights, powers and remedies otherwise provided herein or by applicable law; and
notwithstanding such rights, if any, of the holders of Senior Indebtedness under this Section 9, nothing contained in this Section 9 shall impair the Purchasers' right to convert the
principal and interest of this Note into equity securities of the Company in accordance with Section 5 hereof. 


        9.6    Lien Subordination.    Any lien or security interest of the
Purchaser, whether now or hereafter existing in connection with the amounts due under this Note, on any assets or property of the Company or any proceeds or revenues therefrom which the Purchaser may
have at any time as security for any amounts due and obligations under this Note, including, without limitation, any Lien on or in the Collateral pursuant to the Security Agreement, shall be
subordinate to all liens or security interests now or hereafter granted to a holder of Senior Indebtedness by the Company or by law notwithstanding the date, order or method of attachment or
perfection of any such lien or security interest or the provisions of any applicable law. 


        9.7    Applicability of Priorities.    The priority of the holder of
the Senior Indebtedness provided for herein with respect to security interests and liens are applicable only to the extent that such security interests and liens are enforceable and have not been
avoided; if a security interest or lien is judicially
determined to be unenforceable or is judicially avoided with respect to any claim of the holder of the Senior Indebtedness or any part thereof, the priority provided for herein shall not be available
to such security interest or lien to the extent that it is avoided or determined to be unenforceable. The foregoing notwithstanding, the Purchaser covenants and agrees that it shall not challenge,
attack or seek to avoid any security interest or lien to the extent that it secures any holder of the Senior Indebtedness. Nothing in this Section 9.7 affects the operation of any subordination
of indebtedness or turnover of payment provisions hereof, or of any other agreements among any of the parties hereto. 



        9.8    Reliance of Holders of Senior Indebtedness.    The Purchaser,
by its acceptance hereof, shall be deemed to acknowledge and agree that the foregoing subordination provisions are, and are intended to be, an inducement to and a consideration of each holder of
Senior Indebtedness, whether such Senior Indebtedness was created or acquired before or after the creation of the indebtedness evidenced by this Note, and each such holder of Senior Indebtedness shall
be deemed conclusively to have relied on such subordination provisions in acquiring and holding, or in continuing to hold, such Senior Indebtedness. 



10.    Fractional Shares.    No fractional shares shall be issued upon conversion of
this Note. In lieu of any fractional shares to which the Purchaser would otherwise be entitled, after combining any fractional 


4







 



interests
of the Purchaser into as many whole shares as is possible, the Purchaser shall be paid in cash an amount equal to the product resulting from multiplying such fraction by the then current
Fair Market Value of one share of Preferred Stock (as defined in, and calculated in accordance with, the Warrant). 


11.    No Impairment.    Except and to the extent as waived or consented to by the
Majority Lenders in accordance with Section 15 below, the Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of any debt or equity securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Note in order to protect the rights of Purchaser hereunder against impairment. 



12.    Highest Lawful Rate.    Anything herein to the contrary notwithstanding, if
during any period for which interest is computed hereunder, the amount of interest computed on the basis provided for in this Note, together with all fees, charges, and other payments or rights which
are treated as interest under applicable law, as provided for herein or in any other document executed in connection herewith, would exceed the amount of such interest computed on the basis of the
Highest Lawful Rate (as defined below), the Company shall not be obligated to pay, and the Purchaser shall not be entitled to charge, collect, receive, reserve, or take, interest in excess of the
Highest Lawful Rate, and during any such period the interest payable hereunder shall be computed on the basis of the Highest Lawful Rate. "Highest Lawful
Rate" means the maximum non-usurious rate of interest, as in effect from time to time, which may be charged, contracted for, reserved, received, or collected by the
Purchaser in connection with this Note under applicable law. In accordance with this section, any amounts received in excess of the Highest Lawful Rate shall be applied towards the prepayment of
principal then outstanding. 


13.    Waiver.    Subject to any other provision herein or in the other Loan
Documents, the Company hereby waives demand, notice, presentment, protest and notice of dishonor. 


14.    Governing Law.    This Note shall be governed by and construed under the laws
of the State of California as applied to agreements among California residents, made and to be performed entirely within the State of California, without giving effect to conflicts of laws principles. 


15.    Modification; Waiver.    Any provision of this Note may be amended or waived
by the written consent of the Company and the Majority Lenders. 


16.    Counterparts.    This Note may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
