Section 2.03           Earn-Out.

(a)           As promptly as practicable after the first and second anniversaries of the last day of the calendar month that includes the Closing Date (each 12-month period immediately prior to each such date being herein referred to as an "Earn-Out Period," the Earn-Out Period ending on such first anniversary being herein referred to as the "2009 Earn-Out Period" and the Earn-Out Period ending on such second anniversary being

herein referred to as the "2010 Earn-Out Period"), but in no event later than thirty (30) Business Days thereafter, the Purchaser shall deliver to the Sellers' Representative a certificate signed by the Chief Financial Officer or similar officer of the Purchaser setting forth the Gross Profit with respect to the Diagna Customers for the relevant Earn-Out Period (the "Earn-Out Statement").  Each respective Earn-Out Statement shall be prepared based upon amounts used in preparation of the unaudited income statement of the Purchaser as of the last day of the appropriate Earn-Out Period, which such unaudited income statement shall be prepared in accordance with GAAP (as in effect on the Closing Date) applied consistently with the unaudited income statement of the Company for the period ending March 31, 2008.

(b)           Within thirty (30) days after receipt of each Earn-Out Statement (the "Earn-Out Objection Period"), the Sellers' Representative by written notice to the Purchaser may object to any items shown thereon, setting forth in such notice (the "Earn-Out Objection Notice") the Sellers' Representative's objection in reasonable detail and the Sellers' Representative's proposal or proposals with respect to the calculation of any items shown thereon.  Within twenty (20) days following timely delivery of the Earn-Out Objection Notice, the Purchaser and the Sellers' Representative shall attempt, in good faith, to resolve all disputes between them concerning the Earn-Out Objection Notice.  If the Purchaser and the Sellers' Representative cannot resolve such disputes within such twenty (20) day period, then all disagreements will be submitted for resolution to the Independent Accountant.  Promptly, but not later than twenty (20) days after the dispute has been submitted to the Independent Accountant, the Independent Accountant shall determine (based solely on presentations by the Sellers' Representative and the Purchaser to the Independent Accountant, and not by independent review) only those items in dispute and will render its report as to its resolution of such terms and resulting calculations of the items set forth in such Earn-Out Statement.  In determining each disputed item, the Independent Accountant may not assign a value to such item greater than the greatest value for such item claimed by either party or less than the lowest value for such term claimed by either party.  For the purposes of the Independent Accountant's calculation of the Gross Profit, the amounts to be included shall be the appropriate amounts from such Earn Out Statement as to items that are not in dispute, and the amounts determined by the Independent Accountant as to items from the Earn-Out Objection Notice that are submitted for resolution by the Independent Accountant.  The Sellers' Representative and the Purchaser shall cooperate with the Independent Accountant in making its determination and such determination shall be conclusive and binding upon the parties hereto.  The costs and fees related to such determination by the Independent Accountant, including the costs relating to any negotiations with the Independent Accountant with respect to the terms and conditions of such Independent Accountant's engagement, will be paid by the Purchaser and the Sellers on an inversely proportional basis, based upon the relative portions of the amounts in dispute that have been submitted to the Independent Accountant for resolution that ultimately are awarded to each of the Purchaser and the Sellers (e.g., if $100,000 is in dispute, and of that amount the Independent Accountant awards $75,000 to the Purchaser and $25,000 to the Sellers,

10

then the Purchaser will be responsible for 25%, and the Sellers 75%, of the costs and fees of the Independent Accountant).

(c)           If the Sellers' Representative does not deliver an Earn-Out Objection Notice during the Earn-Out Objection Period, then the Sellers shall be deemed to have accepted the Earn-Out Statement for the relevant Earn-Out Period.  The Earn-Out Statement, either (i) as accepted by the Sellers' Representative pursuant to the preceding sentence, (ii) as agreed to by the Purchaser and the Sellers' Representative, or (iii) as adjusted by the Independent Accountant pursuant to the Section 2.03(b), will be final and binding and will be referred to as the "Final Earn-Out Statement" for the relevant Earn-Out Period (the Final Earn-Out Statement for the 2009 Earn-Out Period being herein referred to as the "2009 Final Earn-Out Statement" and the Final Earn-Out Statement for the 2010 Earn-Out Period being herein referred to as the "2010 Final Earn-Out Statement").

(d)           For the 2009 Earn-Out Period, within fifteen (15) days following the delivery of the 2009 Final Earn-Out Statement, the Purchaser will pay to the Sellers, as an adjustment to the Purchase Price, the amount, if any, payable based on the 2009 Gross Profit as set forth in the 2009 Final Earn-Out Statement determined in accordance with Annex III attached hereto (the "2009 Earn-Out Payment").

(e)           For the 2010 Earn-Out Period, within fifteen (15) days following the delivery of the 2010 Final Earn-Out Statement, the Purchaser will pay to the Sellers, as an adjustment to the Purchase Price, the amount, if any, payable based on the 2010 Gross Profit as set forth in the 2010 Final Earn-Out Statement determined in accordance with Annex IV attached hereto (the "2010 Earn-Out Payment").

(f)            All payments made to the Sellers by the Purchaser pursuant to Section 2.03(d) and Section 2.03(e) (collectively, the "Earn Out Payments") shall be made by wire transfer of immediately available funds to the Purchase Price Bank Account (to be distributed by the Sellers' Representative among the Sellers in accordance with each such Seller's Applicable Percentage of such amount).

(g)           Notwithstanding anything else herein to the contrary, in no event shall the aggregate payments by the Purchaser pursuant to this Section 2.03 exceed a maximum of $1,100,000.00 for any Earn-Out Period or $2,200,000.00 in the aggregate for both Earn-Out Periods.

(h)           During the Earn-Out Objection Period and while any dispute that is the subject of an Earn-Out Objection Notice is pending, the Purchaser shall (i) provide to the Sellers' Representative and his authorized representatives reasonable access during normal business hours to the books, records and employees of the Company, the Purchaser, and each Affiliated Medical Practice and (ii) cooperate with reasonable requests of the Sellers' Representative and/or his authorized representatives with respect to information requested by them in connection with their review of the amounts set forth

in the Earn-Out Statements (including, without limitation, by providing on a timely basis copies of the Purchaser's work papers used in the calculation of the amounts set forth on the Earn-Out Statement).

(i)            Within fifteen (15) days after the end of each calendar month during the 2009 Earn-Out Period and the 2010 Earn-Out Period, Purchaser shall provide Sellers'  Representative with a statement showing a good faith estimate of (i) the amount of Gross Profit earned during the prior month and (ii) the cumulative Gross Profit earned during the applicable Earn-Out Period.  Such statement shall be provided for informational purposes only, and shall not be deemed an acknowledgment or admission of the accuracy of the calculations set forth thereon or otherwise be construed as a waiver of the Purchaser's right to deliver an Earn-Out Statement that differs from such statement or the Sellers' Representative's right to object to the calculation of the amounts set forth in any Earn-Out Statement or any other rights of the Purchaser or the Sellers' Representative.

Section 2.04           Adjustment to Purchase Price Based on Adjusted Working Capital.

(a)           An Indemnified Party shall give the Indemnifying Party notice of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within sixty (60) days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VIII except to the extent that the Indemnifying Party is materially prejudiced by such failure.

(b)           If an Indemnified Party shall receive notice of any Action, audit, claim, demand or assessment (each, a "Third Party Claim") against it which may give rise to a claim for Loss under this Article VIII, within thirty (30) days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party and the Company notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article

44

VIII except to the extent that the Indemnifying Party is materially prejudiced by such failure.  The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if (i) it gives notice of its intention to do so to the Indemnified Party within fifteen (15) days of the receipt of such notice from the Indemnified Party and agrees in advance that it will indemnify the Indemnified Party from and against all Losses the Indemnified Party may suffer arising out of or resulting from the Third Party Claim, and (ii) the Third Party Claim involves only monetary damages.  If the Indemnifying Party elects to undertake any such defense against a Third Party Claim, the Indemnified Party may participate in such defense at its own expense; provided, that, if in the reasonable opinion of counsel to the Indemnified Party, a conflict exists between the Indemnified Party and the Indemnifying Party that would make separate representation advisable, the Indemnified Party may retain separate counsel at the expense of the Indemnifying Party.  The Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party's expense, all witnesses, pertinent records, materials and information in the Indemnified Party's possession or under the Indemnified Party's control relating thereto as is reasonably required by the Indemnifying Party.  The Indemnified Party shall not pay, or permit to be paid, any part of such Third Party Claim unless the Indemnifying Party consents in writing to such payment or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Party is entered against the Indemnified Party for such Third Party Claim.  If the Indemnified Party assumes the defense of any such claims or proceeding pursuant to this Section 8.05(b) and proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the Indemnified Party shall give the Indemnifying Party prompt written notice thereof and the Indemnifying Party shall have the right to participate in the settlement or assume or reassume the defense of such claims or proceeding.

Section 8.06           Remedies.  The Purchaser and the Sellers acknowledge and agree that following the Closing, the indemnification provisions of Article VIII and Article IX and the provisions of any Ancillary Document shall be the sole and exclusive remedies of the Purchaser and the Sellers for any breach by the other party of the representations and warranties in this Agreement or in any Ancillary Agreement and for any failure by the other party to perform and comply with any covenants and agreements in this Agreement or in any Ancillary Agreement, except that if any of the provisions of this Agreement are not performed in accordance with their terms or are otherwise breached, the parties hereto shall be entitled to specific performance of the terms thereof in addition to any other remedy at law or equity.

Section 8.07           Right to Set-Off.  Any indemnification amount payable under this Article VIII by the Sellers shall be, to the extent permitted by Law, an adjustment to the Purchase Price.  The indemnification obligations of the Sellers set forth in this Article VIII and the payment obligations of Seller set forth in Section 2.04(f) arising at any time shall be satisfied, in whole or in part, first, from the Escrow Cash, in accordance with the terms of the Escrow Agreement and, second, at the option of the Purchaser, by offset against any portion of the Earn-Out Payments

45

not yet paid to the Sellers at the time such indemnification obligation or payment obligation becomes due and payable.

(b)           The Company will not file an amended Tax Return or make an election with respect to periods or portions thereof ending on or before the Closing without the written consent of the Purchaser if the amendment or election adversely affects the Purchaser, the Assets, or the business conducted by the Company.

Section 9.02           Allocation for Straddle Period.  For purposes of this Agreement, the amount of Taxes of the Company attributable to the pre-Closing portion of any taxable period beginning before and ending after the Closing Date (the "Straddle Period") shall be determined based upon a hypothetical closing of the taxable year on such Closing Date with the Closing Date being included in the pre-Closing portion of such Straddle Period; provided, however, real and personal property Taxes (which are not based on income) shall be determined by reference to the relative number of days in the pre-Closing and post-Closing portions of such Straddle Period.

Section 9.03           Indemnification.  Zarlingo, jointly and severally, and the other Sellers, severally, agree to indemnify, defend and hold harmless the Purchaser, its Affiliates (including the Company) and the successors to the foregoing (and their respective shareholders, officers, directors, employees and agents) against (i) all Taxes imposed on the Company or asserted against the properties, income or operations of the Company for any taxable period of the Company or portion thereof ending on or prior to the Closing Date including the pre-Closing portion of any Straddle Period; (ii) Taxes of any member of a consolidated group of which the Company (or any predecessor of any of the foregoing) is or was a member on or prior to the

Section 9.04           Survival.  This Article IX shall survive until three (3) months after the expiration of the statute of limitations with respect to the applicable Tax.

Section 9.05           Transfer Taxes.  The Sellers shall be responsible for the preparation of Tax Returns (including any documentation) with respect to all transfer, documentation, sales, use, stamp, registration, and similar Taxes incurred in connection with this Agreement or any transaction contemplated thereby and shall be responsible for the payment of such Taxes.  The Sellers shall file with the Purchaser's cooperation all necessary documentation and Tax Returns with respect to such Taxes.

Section 9.06           Character of Payments.  To the extent permitted by applicable law, the parties agree that any indemnification payments (and/or payments or adjustments) made with respect to this Agreement shall be treated for all Tax purposes as an adjustment to the Purchase Price.

Section 9.07           Termination of Existing Tax-Sharing Agreements.  All Tax-sharing agreements or similar arrangements with respect to or involving the Company shall be terminated with respect to the Company diaries prior to the Closing Date, and, after the Closing Date, neither the Sellers and their Affiliates, on the one hand, nor the Company, on the other, shall be bound thereby or have any liability thereunder to the other party for amounts due in respect of such agreements and arrangements.

Section 9.08           Tax Treatment; Allocation.  Except as otherwise provided by Law, the parties intend to treat the transactions contemplated by this Agreement as a transaction described by Situation Two of IRS Revenue Ruling 99-6, 1999-1 C.B. 432.  The parties acknowledge that the Purchase Price shall be allocated among the assets of the Company (the "Purchase Price Allocation") as agreed by the Purchaser and the Sellers' Representative in writing after Closing, provided that such allocation shall be consistent with the principles set forth in Section 9.08 of the Disclosure Schedule.  Each of the parties hereto will not take a position on any Tax Return, before any governmental agency charged with the collection of any Tax, or in any judicial proceeding, that is in any way inconsistent with the Purchase Price Allocation.  Notwithstanding the tax treatment of the transactions contemplated by this Agreement under such IRS Revenue Ruling, the Parties each agree that the transaction contemplated by this Agreement constitutes a sale of membership interests by the Sellers to the Purchaser.

47

Section 9.09           Sole Tax Provision.  This Article IX shall be the sole provision governing indemnities for Taxes under this Agreement.

Section 10.02         Effect of Termination.  If either the Purchaser or the Sellers decide to terminate this Agreement pursuant to Section 10.01, such party shall promptly give written notice to the other party of such decision.  In the event of a proper termination pursuant to Section 10.01, the parties hereto shall be released from all liabilities and obligations arising under this Agreement with respect to the matters contemplated by this Agreement, except that nothing in this Section 10.02 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement.

ARTICLE XI

GENERAL PROVISIONS

Section 11.01         Dispute Resolution.Anything else in this Agreement, or any other document or instrument to the contrary notwithstanding and with the exception of any dispute(s) which may arise under Sections 2.03 and 2.04 (which disputes, if any, shall be resolved in the manner set forth therein), any controversy, claim, dispute, question or disagreement arising out of or relating to this Agreement or the breach thereof, or any Ancillary Agreement or other agreements or instruments relating hereto or delivered in connection herewith, including but not limited to a claim based on or arising from an alleged tort (any of the foregoing, a "Dispute Subject to Resolution"), shall be settled by use of the dispute resolution process set forth in this Section 11.01.  In the event of a Dispute Subject to Resolution, the parties shall use their best efforts to settle the same.  To this effect, they shall consult and negotiate with each other in good faith and, recognizing their mutual interests, attempt to reach a solution satisfactory to all parties.

(a)           Mediation.  The complaining party shall have the option of pursuing non-binding mediation or arbitration.  In the event the complaining party chooses the option of non-binding mediation, the complaining party shall send a written notice in accordance with Section 11.03 to the other party requesting mediation of the matter to be administered by JAMS in a proceeding held in Chicago, Illinois ("Request for Mediation").  In such Request, the complaining party may propose a timeframe for the mediation.  Within seven (7) business days after the date of the Request for Mediation, the responding party shall advise the complaining party in writing whether or not the responding party would agree to submit the dispute for non-binding mediation.  The parties agree that the sending of the Request for Mediation as set forth above shall constitute submission of the claims for mediation, and that such submission of claims to a mediator appointed mutually by the parties; provided that such mediator shall have significant experience as professional in the Business or similar field.  In the event the parties decide not to engage in mediation or are unable to resolve their disputes through such non-binding mediation, either party shall have the right to initiate arbitration of the matter.

(b)           Arbitration (which may include mediation during the arbitration).  If the parties are unable to reach agreement through voluntary non-binding mediation or if the parties have not agreed to submit the matter to mediation before arbitration, upon notice by either party to the other, all Disputes Subject to Resolution shall be finally settled by arbitration administered by JAMS in accordance with its Comprehensive Arbitration Rules and Procedures.  The arbitration proceeding shall be held in Chicago, Illinois before a single arbitrator knowledgeable in health care matters mutually agreeable to the Sellers' Representative and the Purchaser, or if the Sellers' Representative and the Purchaser are unable to agree on a single arbitrator, by a panel of three arbitrators, one selected by each party and the other chosen by agreement of the other two arbitrators or failing such selection appointment by JAMS.  Any party may seek a preliminary injunction or other preliminary judicial relief or any interim or provisional relief in any

49

federal court sitting in the city of Chicago, Illinois (or if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any Illinois state court sitting in the city of Chicago, Illinois) that such party believes is necessary to protect the rights or property of such party, pending the arbitral tribunal's determination of the merits of the controversy, and the Parties each hereby irrevocably submit to the jurisdiction of such courts for the purpose of any such action.  The institution and maintenance of an Action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff/claimant, to submit the controversy or claim to arbitration if the other party contests such action for judicial relief.  The Federal Rules of Civil Procedure and not JAMs' Comprehensive Arbitration Rules and Procedures, shall govern the discovery process.  All discovery shall be completed no later than fifteen (15) days prior to the final arbitration hearing.  Unless otherwise agreed by the parties, the final arbitration hearing shall be held within sixty (60) days following the appointment of the arbitrators.  The arbitrators may grant any remedy or relief that the arbitrator deems just and equitable.  The award shall be in writing, accompanied by written conclusions and findings, and shall be signed by a majority of the arbitrators.  The arbitrators may, in the award, allocate all or part of the costs of the arbitration, including the fees of the arbitrator and the reasonable attorneys' fees of the prevailing party.  Judgment on the award may be entered in any court having jurisdiction.  The non-prevailing party shall be entitled to appeal such award in any federal district court sitting in the city of Chicago, Illinois (or if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any Illinois state court sitting in the city of Chicago, Illinois).

B-5

                                                (ii)           At any time after the Effective Date, including following the delivery of a Change Fee Dispute and Indemnity Notice (as defined below) pursuant to Section 1.03(c)(iii), upon delivery by the Sellers' Representative to the Purchaser of an agreement executed by Dr. Davae releasing the Company and the Purchaser of all obligations under the Services Agreement relating to the Change Fee Amount, such agreement to be in form and substance satisfactory to the Purchaser, then the Sellers' Representative and the Purchaser agree to give joint written instructions for the distribution of the Change Fee Amount to the Sellers' Representative.

                                                                (B)           If the Escrow Agent receives a Change Fee Disbursement Request from the Purchaser and the Sellers' Representative provides Escrow Agent with a timely Change Fee Dispute and Indemnity Notice, then the Escrow Agent shall retain the Change Fee Escrow Payment Amount in escrow until it may be disbursed in accordance with the provisions set forth below in this Section 1.03(c)(iii)(B).  The Parties agree that following receipt of any timely Change Fee Dispute and Indemnity Notice, the Escrow Agent shall release all or a portion of the Change Fee Payment Escrow Amount (1) in accordance with the joint written instructions of the Sellers' Representative and Purchaser, as they may deliver from time to time; (2) in accordance with the terms of a final non-appealable written order from a court of competent jurisdiction directing the Escrow Agent to disburse all or a portion of the Change Fee Escrow Payment Amount, accompanied by a legal opinion, reasonably satisfactory to the Escrow Agent and the Purchaser, to the effect that the order is final and non-appealable or that the time for appeal has lapsed, or (2) in accordance with the terms of any settlement agreement executed by Dr. Davae settling the dispute that may be delivered by the Sellers' Representative.  For purposes of clarity, the settlement referenced in clause (2) of the preceding sentence shall mean a settlement agreement with respect to the dispute that includes a full release of the Company and the Purchaser with respect to the dispute.  Upon settlement of all outstanding matters relating to the dispute, any portion of Change Fee Payment Escrow Amount not used to satisfy Change Fee

B-6

Dispute Losses shall be distributed to the Sellers' Representative, and the Sellers' Representative and the Purchaser agree to promptly deliver joint written instructions to the Escrow Agent to cause the distribution to the Sellers' Representative of such excess amount.

                                                (v)           The Parties agree that the indemnification obligation of the Sellers pursuant to Section 8.02(d) of the Purchase Agreement shall remain in full force and effect notwithstanding any release of the Change Fee Amount in accordance with the provisions of this Agreement.

                                                (vi)          Simultaneously with the disbursement of any portion of the Change Fee Payment Escrow Amount to the Purchaser or the Sellers' Representative pursuant to this Section 1.03(c), the Escrow Agent shall disburse to the Sellers' Representative all accrued Income and Investment Proceeds attributable to the Change Fee Payment Escrow Amount pursuant to Section 1.03(d) below.

                                                (vi)          Notwithstanding the foregoing, the Change Fee Payment Escrow Amount may otherwise be distributed:  (i) in accordance with any joint written instructions of the Sellers' Representative and the Purchaser with respect to the Change Fee Payment Escrow Amount; or (ii) in accordance with either a final certified copy of an order from JAMS or a final non-appealable order of a court of competent jurisdiction.

                (c)           Tax Liability of the Escrow Agent.  To the extent that the Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of the Escrow Property, the Escrow Agent shall satisfy such liability to the extent possible from the Escrow Property.  The Parties agree, jointly and severally, to indemnify, defend and hold the Escrow Agent harmless from and against any tax, late payment, interest, penalty or other cost or expense that may be assessed against the Escrow Agent on or with respect to the Escrow Property and the investment thereof unless any such tax, late payment, interest, penalty or other expense was caused by the gross negligence or willful misconduct of the Escrow Agent.  The indemnification provided by this Section 1.04(c) is in addition to the indemnification provided in Section 3.01 and shall survive the resignation or removal of the Escrow Agent and the termination of this Escrow Agreement.

                Section 3.03 Resignation or Removal of the Escrow Agent.  The Escrow Agent may resign at any time by furnishing written notice of its resignation to the Purchaser and Sellers' Representative.  The Purchaser and Sellers' Representative may remove the Escrow Agent at any time by furnishing to the Escrow Agent a joint written notice of its removal along with payment of all fees and expenses to which it is entitled through the date of termination.  Such resignation or removal, as the case may be, shall be effective on the date specified in such notice and the Escrow Agent's sole responsibility thereafter shall be to safely keep the Escrow Property and to deliver the same to a successor escrow agent as shall be appointed by the Purchaser and/or Sellers' Representative as evidenced by a joint written notice filed with the Escrow Agent or in accordance with a court order.  If the Purchaser and Sellers' Representative have failed to appoint a successor prior to the expiration of thirty (30) days following receipt of the notice of resignation or removal, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor Escrow Agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the Parties.

                (a)           shall be under no obligation to act, except under process or order of court or JAMS, or until it has been adequately indemnified and held harmless to its full satisfaction, and shall sustain no liability for its failure to act pending such process, order or indemnification; and

                (b)           may, in its sole and absolute discretion, interplead any portion of Escrow Property it then holds with any court of competent jurisdiction, and name the Purchaser and Sellers' Representative as parties in such interpleader action.  Upon filing the interpleader action, the Escrow Agent shall be relieved of all liability as to the Escrow Property and shall be entitled to recover from the Purchaser and Sellers' Representative its reasonable attorneys' fees and other costs incurred in commencing and maintaining such action.  In no event shall the institution of such interpleader action impair the rights of the Escrow Agent described elsewhere in this Escrow Agreement.

The Parties other than the Escrow Agent further agree to pursue any redress or recourse in connection with such a dispute, without making the Escrow Agent a party to same.

                Section 3.06         Authority of Parties.  The Escrow Agent shall be under no duty or obligation to ascertain the identity, authority, and/or rights of the Purchaser or Sellers' Representative, or their agents.  Should it be necessary for the Escrow Agent to act upon any instructions, directions, documents or instruments issued or signed by or on behalf of any corporation, partnership, fiduciary or individual acting on behalf of another party hereto, it shall not be necessary for the Escrow Agent to inquire into such corporation’s, partnership’s, fiduciary's or individual's authority.  The Escrow Agent is also relieved from the necessity of satisfying itself as to the authority of the persons executing this Escrow Agreement in a representative capacity on behalf of any of the Parties.

                Section 3.07         Other Agreements.  The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of the terms and conditions of any other agreement, instrument or document other than this Escrow Agreement, including specifically but not limited to the Purchase Agreement whether or not a copy and/or original of such agreement is held as Escrow Property, and the Escrow Agent shall have no duty to know or inquire as to the performance or nonperformance of any provision of any such agreement, instrument or document.  This Escrow Agreement sets forth all matters pertinent to the escrow contemplated hereunder, and no additional obligations of the Escrow Agent shall be inferred from the terms of this Escrow Agreement or any other agreement, instrument or document.  All references in this Escrow Agreement to any other agreement are for the convenience of the Parties other than the Escrow Agent, and the Escrow Agent has no duties or obligations with respect thereto

                Section 3.09  Attachment of Escrow Property; Compliance with Legal Orders.  In the event that any Escrow Property shall be attached, garnished or levied upon by any order issued by JAMS or a court, or the delivery thereof shall be stayed or enjoined by an order of a court, or any order, judgment or decree shall be made or entered by any order by JAMS or a court affecting the property deposited under this Escrow Agreement, the Escrow Agent is hereby expressly authorized, in its sole discretion, to obey and comply with all writs, orders or decrees so entered or issued, which it is advised by legal counsel of its own choosing is binding upon it, whether with or without jurisdiction, and in the event that the Escrow Agent obeys or complies with any such writ, order or decree it shall not be liable to any of the Parties or to any other person, firm or corporation, by reason of such compliance notwithstanding such writ, order or decree be subsequently reversed, modified, annulled, set aside or vacated.
