4.1. Client Payments. When Payor has finally adjudicated the repriced Network Provider claims for Participants, it will remit all Benefit Plan payments to ACS for each such Network Provider.

Payments to ACS shall be accompanied by accurate benefit explanations and calculation of Participant Expenses that will allow ACS to make payment and provide appropriate claims reconciliation information to Network Providers. The parties may agree to electronic transfers of payments and payment information.

4.2. Compensation to Client.

(a) TTC Fee. During the Term of this Agreement, ACS shall pay to the Client the following:

(i) Administrative Fee Payment. ACS shall pay the Client a monthly management fee equal to the percentage of the ACS Revenue of the Client Business set forth on Attachment C that is collected as Revenue as reflected in the financial records of ACS.. All payments to the Client of the Administrative Fee shall be based on cash received and cash paid out by ACS. Monthly payments to the Client representing the Administrative Fee shall be paid on the 15th of each month for the month immediately preceding.

(ii) Implementation Payments. ACS shall make up to four payments to the Client as a fixed implementation fee for the Client’s achievement of certain implementation targets as specified in Attachment C attached hereto, not to exceed [***] in the aggregate. These targets will be measured as (i) the Client presenting for processing by ACS a percentage of its payors set forth in Attachment C actually and actively submitting claims to ACS and (ii) the attainment of monthly Revenue for Covered Services set forth in Attachment C.

Notwithstanding the above, it is the intention of the parties that the Client is to receive an aggregate fee (meaning the total of the Administrative Fee Payment and Implementation Payment) of [***] of the total Revenue attributable to all Covered Services (the “Client Business”) provided to Client Participants during the Term of this Agreement (the “TTC Fee”). Commencing upon the 33rd month of the Term of the Agreement, ACS and the Client shall calculate the total aggregate amount of the Administrative Fee Payments and Implementation Payments paid to the Client and reconcile such payments to equal [***] of the total Revenue attributable to the Client Business. Upon such reconciliation, any differences in the reconciled TTC Fee shall be paid to the Client by ACS or reimbursed to

ACS by the Client, as the case may be, over a period of 18 months in equal installments as an adjustment to future Administrative Fee Payments.

(b) Warrants. ACS shall grant Corporate Health Plans of America, Inc., an affiliate of the Client, warrants to purchase a total of 225,000 shares of ACS common stock at an exercise price equal to the closing price of the Common Stock of ACS reported on the American Stock Exchange as of the Effective Date. The warrants shall vest 25% on the Effective Date and 25% on the subsequent anniversaries of the Effective Date and shall otherwise be in the form attached hereto as Attachment D.

5.	RECORDS, CONFIDENTIALITY AND HIPAA

5.1. Maintenance and Accuracy of Records.

5.2. Audit. During the term of this Agreement and for at least three (3) years after any particular transaction or payment obligation, Client shall keep and maintain detailed and accurate books and records with regard to all claims for services provided by ACS Network Providers.

Underpayments by Client shown by any such audit shall be immediately paid by Client to ACS along with reimbursement of reasonable expenses incurred by ACS in conducting the audit. The audit rights granted pursuant to this Section 5.2 shall also inure to Client with respect to ACS books and records as such relate to the transactions contemplated by this Agreement, and ACS shall keep and maintain detailed and accurate books and records with regard to such transactions during the existence of this Agreement and for at least three (3) years after any particular transaction or payment obligation.

5.3. Confidential Business Information.

5.4. Confidentiality of Records; HIPAA. ACS and Client shall safeguard the privacy of any health information that identifies a particular Participant.

This is to Certify that, FOR VALUE RECEIVED, CORPORATE HEALTH PLANS OF AMERICA, INC. or assigns (“Holder”), is entitled to purchase, subject to the provisions of this Warrant, from AMERICAN CARESOURCE HOLDINGS, INC., a Delaware corporation (the “Company”), up to Two Hundred Twenty-Five Thousand (225,000) fully paid, validly issued and nonassessable shares of Common Stock, par value $.01 per share, of the Company (“Common Stock”) at a price of $1.84 per share during the period from May 21, 2007 to May 21, 2012 in accordance with the schedule set forth in Paragraph (a)(2) below, but not later than 5:00 p.m. New York City Time, on May 21, 2012. The number of shares of Common Stock to be received upon the exercise of this Warrant and the price to be paid for each share of Common Stock may be adjusted from time-to-time as hereinafter set forth. In addition, the number of shares that may be purchased upon the exercise of this Warrant is subject to reduction as set forth in Paragraph (a)(1) below. The shares of Common Stock deliverable upon such exercise, and as adjusted from time-to-time, are hereinafter sometimes referred to as “Warrant Shares” and the exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the “Exercise Price.”

(a) SPECIAL TERMS, VESTING AND EXERCISE OF WARRANT

(1) SPECIAL TERMS. The Holder has entered into an Ancillary Care Services Network Access Agreement with the Company, dated May 21, 2007 (the “Network Access Agreement”), having a term of four (4) years. The Network Access Agreement may be terminated under certain circumstances by either party prior to the end of the four (4) year term (“Early Termination”). Should an Early Termination of the Network Access Agreement occur, this Warrant shall promptly terminate and be of no force or effect with respect to all unvested shares as described below immediately upon the delivery by either party of a Notice of Early Termination in accordance with the terms of the Network Access Agreement.

(2) VESTING SCHEDULE. This Warrant may be exercised through 5:00 p.m. on May 21, 2012 to the extent of the number of vested shares of Common Stock set forth below if upon each such anniversary date, an Early termination has not occurred, as follows:

Date	Number of Shares Vesting
May 21, 2007	56,250
May 21, 2008	56,250
May 21, 2009	56,250
May 21, 2010	56,250

Upon an Early Termination, no additional shares shall vest and all such shares listed above opposite the column for any date following an Early Termination, shall be unvested shares.

(3) EXERCISE OF WARRANT. The vested portion of this Warrant may be exercised in whole or in part at any time or from time-to-time on or after the date indicated above to May 21, 2012 (the “Exercise Period”); provided, however, that (i) if either such day is a day on which banking institutions in the State of New York are authorized by law to close, then on the next succeeding day that shall not be such a day, and (ii) in the event of any merger, consolidation or sale of substantially all the assets of the Company as an entirety (“Change of Control”), the Warrant shall be deemed, on and after the date of such Change of Control to be fully vested and the Holder shall have the right to exercise this Warrant commencing at such time through May 21, 2012 into the kind and amount of shares of stock and other securities (including cash) receivable by a holder of the number of shares of Common Stock into which this warrant might have been exercisable as fully vested. This Warrant may be exercised by presentation and surrender hereof to the Company at its principal office, or at the office of its stock transfer agent, if any, with the Purchase Form annexed hereto duly executed and accompanied by payment of the Exercise Price for the number of Warrant Shares specified in such form. As soon as practicable after each such exercise of the warrants, but not later than seven (7) days from the date of such exercise, the Company shall issue and deliver to the Holder a certificate or certificate for the Warrant Shares issuable upon such exercise, registered in the name of the Holder or its designee. If this Warrant should be exercised in part only, the Company shall, upon surrender of this Warrant for cancellation, execute and deliver a new Warrant evidencing the rights of the Holder thereof to purchase the balance of the Warrant Shares purchasable thereunder. Upon receipt by the Company of this Warrant at its office, or by the stock transfer agent of the Company at its office, in proper form for exercise, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of the Company shall then be closed or that certificates representing such shares of Common Stock shall not then be physically delivered to the Holder.

(4) TERMINATION FOR CAUSE. Notwithstanding the provisions set forth herein, if the Agreement is terminated by the Company for cause under Section 6.3 of the Network Access Agreement, the Warrant terminates and vested options may not be exercised.

(b) RESERVATION OF SHARES. The Company shall at all times reserve for issuance and/or delivery upon exercise of this Warrant such number of shares of its Common Stock as shall be required for issuance and delivery upon exercise of the Warrants.

(c) FRACTIONAL SHARES. No fractional shares or script representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the current market value of a share, determined as follows:

(1) If the Common Stock is listed on a national securities exchange or admitted to unlisted trading privileges on such exchange or listed for trading on the NASDAQ Stock Market, the current market value shall be the last reported sale price of the Common Stock on such exchange or market on the last business day prior to the date of exercise of this Warrant or if no such sale is made on such day, the average closing price and asked prices for such day on such exchange or market; or

(2) If the Common Stock is not so listed or admitted to unlisted trading privileges, but is traded on the NASDAQ Capital Market or the NASDAQ OTC Bulletin Board, the current market value shall be the average of the closing price and asked prices for such day on such market and if the Common Stock is not so traded, the current market value shall be the mean of the last reported price and asked prices reported by NASDAQ on the last business day prior to the date of the exercise of this Warrant; or

(3) If the Common Stock is not so listed or admitted to unlisted trading privileges and bid and asked prices are not so reported, the current market value shall be an amount not less than book value thereof as at the end of the most recent fiscal year of the Company ending prior to the date of the exercise of the Warrant, determined in such reasonable manner as may be prescribed by the Board of Directors of the Company.

(d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is exchangeable, without expense, at the option of the Holder, upon presentation and surrender hereof to the Company or at the office of its stock transfer agent, if any, for other warrants of different denominations entitling the holder thereof to purchase in the aggregate the same number of shares of Common Stock purchasable hereunder. Upon surrender of this Warrant to the Company at its principal office or at the office of its stock transfer agent, if any, with the Assignment Form annexed hereto duly executed and funds sufficient to pay any transfer tax, the Company shall, without charge, execute and deliver a new Warrant in the name of the assignee or assignees named in such instrument of assignment and this Warrant shall promptly be canceled. This Warrant may be divided or combined with other warrants that carry the same rights upon presentation hereof at the principal office of the Company or at the office of it stock transfer agent, if any, together with a written notice specifying the names and denominations in which new Warrants are to be issued and signed by the Holder hereof. The term “Warrant” as

used herein includes any Warrants into which this Warrant may be divided or exchanged. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Warrant, if mutilated, the Company will execute and deliver a new Warrant of like tenor and date. Any such new Warrant executed and delivered shall constitute an additional contractual obligation on the part of the Company, whether or not this Warrant so lost, stolen, destroyed or mutilated shall be at any time enforceable by anyone.

(e) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or equity, and the rights of the Holder are limited to those expressed in the Warrant and are not enforceable against the Company except to the extent set forth herein.

(f) ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any time and the number and kind of securities purchasable upon the exercise of the Warrants shall be subject to adjustment from time-to-time in case the Company shall: (i) declare a dividend or make a distribution on its outstanding shares of Common Stock in shares of Common Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect at the time of the record date for such dividend or distribution or of the effective date of such subdivision, combination or reclassification shall be adjusted so that it shall equal the price determined by multiplying the Exercise Price by a fraction, the denominator of which shall be the number of shares of Common Stock outstanding after giving effect to such action, and the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such action. Such adjustment shall be made successively whenever any event listed above shall occur.

Whenever the Exercise Price payable upon exercise of each Warrant is adjusted as set forth in this Section (f), the number of Shares purchasable upon exercise of this Warrant shall simultaneously be adjusted by multiplying the number of Shares initially issuable upon exercise of this Warrant by the Exercise Price in effect on the date hereof and dividing the product so obtained by the Exercise Price, as adjusted.

(g) RECLASSIFICATION AND REORGANIZATION. Except for a Change of Control as described in Section 3 hereof, in case of any reclassification, capital reorganization or other change of the characteristics of outstanding shares of Common Stock of the Company, the Company shall, as a condition precedent to such transaction, cause effective provisions to be made so that the Holder shall have the right thereafter by exercising this Warrant at any time prior to the expiration of the Warrant, to purchase the kind and amount of shares of stock and other securities and property receivable upon such reclassification, capital reorganization and other change by a holder of the number of shares of Common Stock that might have been purchased upon exercise of this Warrant immediately prior to such reclassification, reorganization or change of the characteristics of outstanding shares of Common Stock of the

Company. Any such provision shall include provision for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Warrant. The foregoing provisions of this Section (g) shall similarly apply to successive reclassifications, capital reorganizations and changes of shares of Common Stock. In the event that in connection with any such capital reorganization or reclassification, additional shares of Common Stock shall be issued in exchange, conversion, substitution or payment, in whole or in part, for security of the Company other than Common Stock, any such issue shall be treated as an issue of Common Stock covered by the provisions of Section (f) hereof.

(h) COMPLIANCE WITH SECURITIES ACT.

(1) Unregistered Securities. The Holder acknowledges that neither this Warrant, nor the Warrant Shares, have been registered under the Securities Act and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this Warrant or any Warrant Shares in the absence of (i) an effective registration statement under the Securities Act covering this Warrant or such Warrant Shares and registration or qualification of this Warrant or such Warrant Shares under any applicable “blue sky” or state securities law then in effect, or (ii) the availability of an exemption from any such registration and qualification.

(2) Legend. Any certificates delivered to the Holder representing Warrant Shares shall bear the following legend or a legend in substantially similar form:

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN TAKEN FOR INVESTMENT AND THEY MAY NOT BE SOLD OR OTHERWISE TRANSFERRED BY ANY PERSON, INCLUDING A PLEDGEE, IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR IF AN EXEMPTION FROM REGISTRATION IS THEN AVAILABLE.”

(i) GOVERNING LAW. This Warrant will be governed by and construed in accordance with and governed by the laws of Delaware, without giving effect to the conflict of law principles thereof.

(j) NOTICES. All notices, requests and other communications hereunder shall be in writing, shall be either (i) delivered by hand, (ii) made by facsimile transmission, (iii) sent by overnight courier, or (iv) sent by registered mail, postage prepaid, return receipt requested. In the case of notices from the Company to the Holder, they shall be sent to the address furnished to the Company in writing by the last Holder who shall have furnished an address to the Company in writing. All notices from the Holder to the Company shall be delivered to the Company at its offices at 0000 Xxxxxx X. Xxxxxxx Xxxxxxx, Xxxxx 000, Xxxxxx, XX 00000 facsimile (972) 308-6830 or such other address or facsimile number as the Company shall so notify the Holder. All notices, requests and other communications hereunder shall be deemed to have been given (i) by hand, at the time of the delivery thereof to the receiving party at the address of such party

described above, (ii) if made by facsimile transmission, at the time that receipt thereof has been acknowledged by electronic confirmation or otherwise, (iii) if sent by overnight courier, on the next business day following the day such notices is delivered to the courier service, or (iv) if sent by registered mail, on the fifth (5th) business day following the day such mailing is made.
