  which there are made not misleading. 

 - 5 - 

                (f)          
  Absence of Certain Changes or Events.

                               (i)          
  Except to the extent disclosed in the SEC Reports, since December 31, 2003,
  there has not occurred a material adverse change in respect of Parent. 

                               (ii)          Neither
  Parent nor Purchaser is in default under any material agreement to which it
  is a party or to which its assets are subject, and no event has occurred or
  circumstances exists which, with the giving of notice or the passage of time
  or both, would constitute such a default. 

                (g)          
  Absence of Litigation. Except as set forth in the SEC Reports, there
  is no litigation pending, or to the knowledge of Parent’s Chief Executive
  Officer, after reasonable investigation, threatened against Parent that could
  result in a material adverse change with respect to Parent. Parent is not subject
  to any outstanding claim or order other than as set forth in the SEC Reports,
  which, individually or in the aggregate could result in a material adverse change
  in respect of Parent. Parent has made available to Seller all written correspondence
  from the Securities and Exchange Commission received during the twelve months
  immediately preceding the date of this Agreement and all written correspondence
  from Nasdaq or any exchange or trading system on which Parent common stock is
  listed, traded or quoted closing conditions. 

                (h)          
  Investment Representation; Accredited Investor. Purchaser is acquiring
  the Membership Interest for its own account for purposes of investment and not
  with a view to the distribution thereof or dividing all or any part of its interest
  therein with any other person or entity. Purchaser acknowledges that the sale
  of the Membership Interest has not been registered under applicable laws (including
  the Securities Act, any state, local or foreign securities laws) and that such
  shares may not be transferred without registration under, pursuant to an exemption
  from or in a transaction not subject to, all applicable law. Purchaser acknowledges
  that the Membership Interest, if certificated, will bear a restrictive legend
  and that such certificated interest may only be transferred following the removal
  of such legend by Purchaser. Purchaser is an “accredited investor”
  as that term is defined in Rule 501(a) of Regulation D promulgated under the
  Securities Act. Purchaser had the opportunity to discuss Seller’s business,
  management and financial affairs with Seller and its management team. Purchaser
  has such knowledge and experience in financial and business matters, or has
  been adequately advised by financial representatives, that Purchaser is capable
  of evaluating the merits and risks of the Membership Interest.

  to the limitations set forth in Section 6.3, from and after the Closing Date,
  Seller shall indemnify and hold Purchaser harmless from and against, and agree
  to promptly defend Purchaser from and reimburse Purchaser for, any and all losses,
  damages, costs, expenses, liabilities, obligations and claims of any kind (including,
  without limitation, reasonable attorneys’ fees and other reasonable legal
  costs and expenses, including without limitation, those incurred in connection
  with any suit, action or other proceeding) (“Losses”) which
  Purchaser may at any time, subject to the terms of Section 6.3 hereof, suffer
  or incur, or become subject to, as a result of or in connection with: 

                (a)          
  Any inaccuracy in or breach of any representation and warranty made by Seller
  in this Agreement or in any closing document delivered to Purchaser in connection
  with this Agreement; and 

                (b)          
  Any breach by Seller of, or failure by Seller to comply with, any of its covenants
  or obligations under this Agreement (including, without limitation, its obligations

 6.2           Indemnity
  by Purchaser. From and after the Closing Date, Purchaser shall indemnify
  and hold Seller harmless from and against, and agrees to promptly defend Seller

                (a)

  be liable under Sections 6.1 and 6.2 of this Agreement shall be net of any insurance
  proceeds actually received by the indemnified party in connection with the facts
  giving rise to the right of indemnification. 

 - 9 - 

                (b)          
  Termination of Rights to Indemnity. The right of the Purchasers to receive
  indemnity as provided in Section 6.1 shall expire on the date that is 12 months
  after the Closing Date, except as to any claim for indemnity that has been described

  prior to such time. The right of the Seller to receive Indemnity as provided
  in Section 6.2 shall expire on the date of the last payment made in full satisfaction

                (c)          
  Rights on Termination. The termination under Section 6.3(b) of the rights
  of an indemnified party to receive indemnity shall not affect that person’s

                (d)          
  Limitations on Liability of Seller. The liability of Seller under Section
  6.1 of this Agreement shall be without deduction or limitation, except that
  such liability shall be only to a maximum amount of $1.5 million and may
  be payable in the form of the Promissory Note. Seller may, at Seller’s
  discretion, offset any amount that Seller may owe to Purchaser, if any, as indemnity
  pursuant to this Article 6, against amounts owed by Purchaser to Seller under
  the Note. 

 6.4           Indemnification
  Procedure. 

                (a)          
  Notice. If an indemnified party shall claim to have suffered a Loss for
  which indemnification is available under Section 6.1 or 6.2, as the case may
  be, the indemnified party shall notify the indemnifying party in writing of
  such claim, which notice shall describe the nature of such claim, the facts
  and circumstances that give rise to such claim and the amount of such claim
  if reasonably ascertainable at the time such claim is made. In the event that
  within 45 days after the receipt by the indemnifying party of such a written
  notice from the indemnified party, the indemnified party shall not have received
  from the indemnifying party a written objection to such claim, such claim shall
  be conclusively presumed and considered to have been assented to and approved
  by the indemnifying party following receipt by the indemnifying party (and,
  in the case of a claim by Purchaser, the escrow agent) of a written notice from
  the indemnified party to such effect. 

                (b)          
  Resolution. If within the 45 day period described in paragraph (a) above
  the indemnified party shall have received from the indemnifying party a notice
  setting forth the indemnifying party’s objections to such claim and the
  indemnifying party’s reasons for such objection, then the parties shall
  follow the procedures set forth in Section 6.5 below with respect to the resolution
  of such matter. 

                (c)          
  Third-Party Claims.

                               (i)          
  Any indemnified party seeking indemnification pursuant to this Article 6 in
  respect of any third-party claim shall give the indemnifying party from whom
  indemnification with respect to such claim is sought (A) prompt (but in any
  event no later than 45 days after such indemnified party has received notice
  of such third party claim) written notice of such third-party claim and (B)
  copies of all documents and information provided by the third party to the indemnified
  party in connection with such claim. The failure of the indemnified party to
  so 

 - 10 - 

notify or provide copies to the indemnifying party shall not relieve the indemnifying party from any liability to the indemnified party for any liability hereunder except to the extent that such failure shall have prejudiced the defense of such
third-party claim. 

                               (ii)         
  The indemnifying party shall have the right to participate in the defense of
  such claim and at its option to assume the defense thereof using counsel reasonably
  acceptable to the indemnified party. After notice from the indemnifying party
  to the indemnified party of its election to assume the defense of such claim,
  the indemnified party may continue to participate in the defense of such claim,
  but, except as set forth in subsection (iii) below, the indemnifying party shall
  not be liable to the indemnified party under this Article 6 for any legal or
  other expenses subsequently incurred by the indemnified party in connection
  with the defense of such claim, other than reasonable costs of investigation.
  If, following its assumption of the defense of a claim pursuant to this Section
  6.4(c), the indemnifying party believes that the claim is not indemnifiable
  pursuant to Section 6.1 or Section 6.2, the indemnifying party shall promptly
  tender back to the indemnified party the defense of such claim. If the indemnifying
  party fails to assume or, if assumed, tenders back the defense of a claim pursuant
  to this Section 6.4(c) and thereafter concludes that it wishes to defend the
  claim, it shall be entitled to do so upon notice to the indemnified party of
  its decision; provided, however, that any such subsequent assumption of defense
  pursuant to this sentence shall constitute an admission by the indemnifying
  party that the claim is indemnifiable pursuant to Section 6.1 or Section 6.2.

                               (iii)         Notwithstanding
  the foregoing, if: (A) the employment thereof is authorized by the indemnifying
  party in writing; (B) the indemnified party shall have been advised by such
  counsel that there may be one or more legal defenses available to it which are
  different from or in addition to those available to the indemnifying party and
  in the reasonable judgment of such counsel it is advisable for the indemnified
  party to employ such counsel; or (C) the indemnifying party has failed to assume
  defense of such claim within 45 days after it receives written notice of such
  claim or to employ counsel reasonably satisfactory to the indemnified party;
  the indemnified party may notify the indemnifying party in writing that it elects
  to employ separate counsel (which counsel shall be reasonably acceptable to
  the indemnifying party) at the expense of the indemnifying party and the indemnifying
  party shall not have the right to assume the defense of such claim, except as
  provided for by the last sentence of Section 6.4(c)(ii) . The indemnifying party
  shall not, in connection with one claim or substantially similar claims in the
  same jurisdiction arising out of the same or substantially similar facts, be
  liable for the reasonable fees and expenses of more than one firm of attorneys,
  which firm shall be designated in writing by the indemnified party. Nothing
  contained in this Section 6.4(c) shall in any way restrict the indemnified party’s
  ability to defend a claim and, if such claim is otherwise indemnifiable pursuant
  to the provisions of this Article 6, to recover all costs associated with such
  defense while the indemnifying party is considering whether to assume the defense
  of a claim tendered to it. 

                               (iv)          
  Each indemnifying party and indemnified party shall use commercially reasonable
  efforts to cooperate with the other in the defense of such claim. The indemnifying
  party shall not be liable for the settlement of any claim affected without its
  written consent, which consent shall not be unreasonably withheld. No such claim
  shall be settled by the indemnifying party without the prior written consent
  of the indemnified party. If a firm, written, 

 - 11 - 

bona fide offer is made by the third party to settle or resolve any third party claim and the indemnifying party proposes to accept such settlement and the indemnified party refuses to consent to such settlement, then: (A) the indemnifying party
shall be excused from, and the indemnified party shall be solely responsible for all further defense of, such claim; (B) the maximum liability of the indemnifying party relating to such claim shall be the amount of the proposed settlement if the
amount thereafter recovered from the indemnified party is greater than the amount of the proposed settlement; and (C) the indemnified party shall pay all attorneys’ fees and legal costs and expenses incurred after the rejection of such
settlement, but if the amount thereafter recovered by the third party from the indemnified party is less than the amount of the proposed settlement, the indemnified party shall also be entitled to reimbursement for such fees and costs up to a
maximum equal to the difference between the amount recovered by such third party and the amount of the proposed settlement. 

 6.5           Dispute
  Resolution Process. If a dispute concerning the interpretation of this Agreement
  or an alleged breach of this Agreement arises, the parties shall follow the
  procedures specified below to resolve the dispute. 

                (a)          
  Negotiations. The parties shall promptly attempt to resolve any dispute
  by negotiations between Purchaser and Seller, as appropriate. 

                (b)          
  Submission to Adjudication. If a dispute is not resolved by negotiation
  pursuant to Section 6.5(a) of this Agreement within 30 calendar days after initiation
  of the negotiation process pursuant to Section 6.5(a) of this Agreement, such
  dispute and any other claims arising out of or relating to this Agreement may
  be heard, adjudicated and determined in an action or proceeding filed in any
  state court in Maricopa County, Arizona or any federal court in the District
  of Arizona. 

                (c)          
  General Provisions Regarding Dispute Resolution.

                               (i)          
  Provisional Remedies. At any time during the procedures specified in
  Sections 6.5(a) of this Agreement, a party may seek a preliminary injunction
  or other provisional judicial relief if in its judgment such action is necessary
  to avoid irreparable damage or to preserve the status quo. Despite such action,
  the parties will continue to participate in good faith in the procedures specified
  in this Section 6.5. 

                               (ii)         
  Tolling Statutes of Limitations. All applicable statutes of limitation
  and defenses based upon the passage of time shall be tolled while the procedures
  specified in this Section 6.5 are pending. The parties will take such action,
  if any, as is required to effectuate such tolling. 

                               (iii)        
  Performance to Continue. Each party is required to continue to perform
  its obligations under this Agreement pending final resolution of any dispute.

                               (iv)         
  Except in the case of fraud, or where a party may be entitled to injunctive
  relief or other equitable remedies, after the Closing, the indemnification provided
  in this Article 6 will constitute the exclusive remedy of the parties and each
  of their respective directors, officers, employees, agents and assigns from
  and against any and all Losses asserted against, resulting to, imposed upon
  or incurred or suffered by, any of them, directly or indirectly, as a 

 - 12 - 

result of, or based upon or arising from the breach of any representation or warranty or the nonfulfillment of any agreement or covenant in or pursuant to this Agreement or any other agreement, document, or instrument required hereunder.

 EXHIBIT A 

 PROMISSORY NOTE 

	  $1,500,000  	 Phoenix, Arizona  
	 	 

                FOR
  VALUE RECEIVED, the undersigned, Diagnostic USA, Inc., a Colorado corporation
  (the “Maker”), promises to pay to Nationwide Diagnostic Solutions,
  Inc., an Arizona corporation (together with its permitted successors and assigns,
  (the “Payee”), in the manner and at the place hereinafter
  provided, the principal amount of $1,500,000. Such sum will be payable in
  accordance with Section 1 of this Promissory Note (this “Note”).

                The
  Maker also promises to pay interest on the unpaid principal amount of this Note
  from the date as first above written and from such other dates as set forth
  in this Note until paid in full at the interest rate of 6.0% per year, except
  as otherwise provided in this Note. Interest on this Note will accrue and will
  be paid pursuant to the payment provisions as herein contained.

                This
  Note is issued pursuant to and subject to the terms and conditions of that certain
  Limited Liability Company Membership Purchase Agreement dated as of January
  7th, 2005 to which Maker and Payee are parties (the “Agreement”).
  Terms not otherwise defined in this Note shall have the same meaning as in the
  Agreement. 

 ARTICLE 1

  TERMS OF REPAYMENT

                1.1         Payment.
  Installments of principal and interest payments in this Note shall be paid pursuant
  to the dividending provisions contained in Article 7.1 of the Agreement. For
  clarity sake, the maker shall pay to the Holder of this Note 50% of all dividends
  received from NEWCO. The parties to the Agreement have also, concurrently therewith
  and herewith, entered into an Amended and Restated Operating Agreement (the
  “Operating Agreement”) for NEWCO in which the parties agree to distribute,
  as dividends, a minimum of 75% of the net profit of NEWCO, on a monthly basis,
  unless otherwise agreed. The first Payment Date will be at such time as the
  first dividends are received from NEWCO. Any payment under this Note will first
  be credited against costs, fees and expenses provided for hereunder, second
  to the payment of accrued and unpaid interest, and the remainder will be credited
  against principal. All amounts due hereunder shall be payable in legal tender
  of the United States of America, by check delivered to the Payee on or before
  each of the Payment Dates; provided that any payment postmarked at least three
  business days prior to its due date shall be deemed to be timely made. If a
  payment hereunder otherwise would become due and payable on a Saturday, Sunday
  or legal holiday, the due date thereof will be extended to the next succeeding
  business day, and interest will be payable thereon during such extension. 

                1.2         Term.
  The term of this note shall be for a period of ten (10) years from the date
  first above written. Any principal and interest remaining outstanding at the
  end of the Term shall be paid in a balloon payment on or before the last day
  of the Term. 

                1.3         
  Prepayments. The Maker may prepay this Note in whole or
  in part at any time without penalty with interest to the date of payment. If
  this Note is prepaid, there is to be no discount from the obligation to pay
  the full principal balance due at the time of prepayment unless mutually agreed
  to by all parties hereto. 

                1.4         Maximum
  Rate of Interest. In no event will the interest rate payable on this
  Note exceed the maximum rate of interest permitted to be charged under applicable
  law. If any holder of this Note collects monies which are deemed to constitute
  interest which would increase the effective interest rate on this Note to a
  rate in excess of the maximum rate permitted to be charged by the laws of any
  applicable jurisdiction, all such sums deemed to constitute interest in excess
  of such maximum rate shall be credited to the payment of the principal amount
  due hereunder or, to the extent such sums exceed the principal balance then
  outstanding, returned to the Maker. 

                1.5         Offset.
  Offset may not be made against this Note for the breach of any provision
  of the Agreement or any other document, or for any damages that may be incurred
  by Maker or any other party.

  any provision of law which renders any such provision prohibited or unenforceable
  in any respect. 

                3.4

  Consent to Jurisdiction, Etc. Maker hereby irrevocably
  consents and agrees that any action, suit or proceeding arising in connection
  with any disagreement, dispute, controversy or claim arising out of or relating
  to this Note (for purposes of this Section, a “Legal Dispute”)
  shall be brought only to the exclusive jurisdiction of the courts of the State
  of Arizona or the federal courts located in the State of Arizona. The Maker
  agrees that, after a Legal Dispute is before a court as specified in this Section
  and during the pendency of such Legal Dispute before such court, all actions,
  suits or proceedings with respect to such Legal Dispute or any other Legal Dispute,
  including, any counterclaim, cross-claim or interpleader, shall be subject to
  the exclusive jurisdiction of such court. The Maker hereby waives and agrees
  not to assert, as a defense in any legal dispute, that it is not subject thereto
  or that such action, suit or proceeding may not be brought or is not maintainable
  in such court or that its property is exempt or immune from execution, that
  the action, suit or proceeding is brought in an inconvenient forum or that the
  venue of the action, suit or proceeding is improper. Maker hereto agrees that
  a final judgment in any action, suit or proceeding described in this Section
  after the expiration of any period permitted for appeal and subject to any stay
  during appeal shall be conclusive and may be enforced in other jurisdictions
  by suit on the judgment or in any other manner provided by applicable laws.

  OPTION AGREEMENT (“Agreement”) is entered into as of the
  ____ day of __________ , 2005, by and between DIAGNOSTIC USA, INC., a Colorado
  corporation (“Optionee”), and NATIONWIDE DIAGNOSTIC SOLUTIONS,
  INC., an Arizona corporation (“Optionor”). Terms not otherwise
  defined in this Agreement shall have the same meaning as in the Limited Liability
  Company Membership Purchase Agreement (“Purchase Agreement”)
  dated January 7th, 2005 by and between Optionor, Optionee, Diagnostic
  Solutions of America, Inc., an Arizona limited liability company (“DSA”)
  and Banyan Corporation, an Oregon corporation and parent of Optionee (“Parent”).

 RECITALS 

                   WHEREAS,
  Optionee, Optionor, Parent and DSA have entered into the Purchase Agreement
  whereby Optionor, in consideration for the Purchase Price, has sold to Optionee,
  in addition to the Membership Interest, an option to purchase from Optionor
  an additional 20% of the membership interests in DSA outstanding as of the date
  of the Purchase Agreement (the “Option Interest”) upon the
  terms and conditions set forth in this Agreement; and 

                    WHEREAS,
  after giving effect to the sale of the Membership Interest as contemplated by
  the Purchase Agreement, Optionor owns 80% of the issued and outstanding membership
  interests of DSA; and 

                   WHEREAS,
  it is the intent of the parties to this Agreement that upon acquisition of the
  Membership Interest and upon exercise of the option by Optionee to acquire the
  Option Interest in accordance with the terms of this Agreement, Optionee will
  own an amount of DSA equal to, but not to exceed, 40% of the issued and outstanding
  membership interests in DSA as of the date of the Purchase Agreement.

                   NOW
  THEREFORE for good and valuable consideration, the receipt and sufficiency
  of which are hereby acknowledged, and in consideration of the mutual covenants
  and agreements herein contained, the parties do hereby mutually covenant and
  agree as follows: 

 AGREEMENT 

                   1.               
  Grant of Option; Nature of the Option Interest. Optionor hereby grants
  to Optionee the option to purchase the Option Interest on the terms and conditions
  hereinafter described. Optionor represents and warrants that (i) it owns the
  Option Interest, (ii) the Option Interest is free and clear of all liens and
  encumbrances, and (iii) it has full power and authority to convey the Option
  Interest in the manner required herein. 

                    2.               
  Purchase Price for Option. In payment for the option granted herein,
  Optionee shall pay to Optionor the Purchase Price in accordance with the Purchase
  Agreement. 

 1 

                   3.               
  Purchase Price and Payment Terms for Purchase of Option Interest. Optionee
  shall have the right to purchase the Option Interest at any time prior to the
  termination or expiration of this option as provided in Section 7 of this Agreement
  and provided that all of the conditions to Optionor’s obligation to close
  set forth in Section 4 of this Agreement have been satisfied. The purchase price
  for the Option Interest is $1,500,000 (the “Option Interest Purchase
  Price”), which amount is payable in cash, or any other mutually agreeable
  form of payment, upon closing. The Optionee shall be permitted to purchase any
  or all of the Option Interest, as it may determine, in its sole discretion.
  The purchase price of the exercise of a portion of the Option Interest shall
  be allocated on a pro rata basis of the purchase price 

                   4.               
  Conditions Precedent to Optionor’s Obligation to Close. The obligation
  of Purchaser to consummate the transaction contemplated by this Agreement is
  subject to the following conditions precedent:

                                     (a)               
  Optionee has provided written notice to the Optionor that it is exercising its
  option to purchase the Option Interest; 

                                     (b)
                 Optionee
  has paid the Option Interest Purchase Price or that portion thereof as required
  for a partial exercise of the Option Interest; 

                                     (c)
                 Optionee
  has paid the Purchase Price in the manner provided in the Purchase Agreement,
  including, but not limited to, all amounts due under the Promissory Note; 

                                     (d)               There
  is no default by Optionee or Parent under the Purchase Agreement or the Promissory
  Note;

                                     (e)               
  Optionee shall assume and indemnify Optionor against all obligations relating
  to the Option Interest that relate to matters arising after the date of said
  closing. 

                   5.               
  Condition Precedent of Optionee’s Obligation to Close. Optionor
  shall convey title to the Option Interest, or that portion thereof that is exercised
  by the Optionee, by endorsing the applicable certificates representing the Option
  Interest to Optionee and causing DSA to recognize Optionee as the owner of such

                   6.               
  Costs. Each party hereto shall be responsible for their own respective
  closing expenses.

                   7.               
  Term and Termination. This Agreement and all option rights granted hereunder
  will terminate upon the failure of the Optionee to pay any part of the Purchase
  Price for the Membership Interest, including but not limited to any amount due
  and owing under the Promissory Note, which amount goes uncured for the periods
  provided in the Promissory Note. Notwithstanding anything herein to the contrary,
  all option rights granted herein shall expire on the ten year anniversary from
  the date of this Agreement, unless they have lapsed earlier due to a failure
  by Optionee to pay the Purchase Price for the Membership Interest. Optionor
  shall have no obligation to close the sale of the Option Interest to Optionee
  after the option rights granted herein have expired.

 PLEDGE, SECURITY AGREEMENT 

  AND COLLATERAL ASSIGNMENT 

  (LLC INTERESTS) 

                THIS
  PLEDGE, SECURITY AGREEMENT AND COLLATERAL ASSIGNMENT (this “Agreement”)
  is made and entered into as of 

  ___________ __, ____, by and among DIAGNOSTIC USA, INC., a Colorado corporation,
  whose address is _______________________ (“Assignor”), DIAGNOSTIC
  SOLUTIONS OF AMERICA, INC., LLC, an Arizona limited liability company, whose
  address is ___________ (the “Company”), and NATIONWIDE DIAGNOSTIC
  SOLUTIONS, INC., an Arizona corporation, whose address is __________________
  (“Assignee”). 

 1.          PLEDGE,
  ASSIGNMENT AND SECURITY INTEREST 

                Assignor
  hereby pledges and collaterally assigns to Assignee, and grants to Assignee
  a security interest (the “Security Interest”) limited to
  10% of the interest the Assignor has acquired in the Company, such right, title
  and interest, secured by that Promissory Note dated concurrently herewith in
  the amount of $1,500,000(the “Collateral”).

 2.          OBLIGATION
  SECURED 

                This
  Agreement shall secure payment and performance of all of the following items:
  (i) that Limited Liability Company Membership Purchase Agreement (the “Purchase
  Agreement”) of on or about even date herewith by and among the Company,
  Assignee, Assignor, and Banyan Corporation, an Oregon corporation; (ii) that
  Promissory Note of on or about even date herewith, in the principal amount of
  $750,000, executed by the Assignor, as maker, for the benefit of Assignee,
  as payee (the “Promissory Note”), plus all interest, fees,
  charges and attorneys’ fees incurred with respect thereto; and (iii) performance
  of this Agreement. All of the indebtedness and obligations secured by this Agreement
  are hereinafter collectively called the “Obligation.” 

 3.          POWER
  OF ATTORNEY 

                Assignor
  irrevocably appoints Assignee its true and lawful attorney-in-fact, in its name
  or otherwise, to do any and all acts, pay any sum and/or to execute any and
  all documents that may in the opinion of the Assignee be necessary or desirable
  to preserve any right of Assignor under the Collateral or enable Assignor to
  assign, transfer or convey the Collateral. If Assignee acting under its authority
  herein granted should pay, suffer or incur any expense, costs, charge, fee,
  obligation, damage or liability of any nature, or be a party to any action or
  proceeding for protecting the Collateral or any rights in the Collateral, all
  of the same and all sums paid by Assignee for prosecution or defense of such
  actions or proceedings, including in any case reasonable attorneys’ fees,
  shall be payable by Assignor to Assignee within 10 days of Assignor’s
  receipt of written demand therefor from Assignee, together with interest thereon
  at the rate set forth in the Promissory Note. Without limiting the foregoing,
  at any time after the occurrence of an Event of Default (as defined below),
  Assignor irrevocably constitutes and 

 appoints Assignee, whether or not the Collateral has been
  transferred into the name of Assignee, as Assignor’s proxy with full power,
  in the same manner, to the same extent and with the same effect as if Assignor
  were to do the same, in the sole discretion of Assignee: (i) to vote the Collateral
  at any meeting of the members or other meeting in which the Collateral is entitled
  to be voted; (ii) to consent to any and all actions by or with respect to the
  Company for which consent of the members of the Company is or may be necessary
  or appropriate; and (iii) without limitation, to do all things that Assignor
  can do or could do as a member of the Company, giving Assignee full power of
  substitution and revocation; provided, however, that this irrevocable proxy
  shall terminate at such time as this Agreement is no longer in full force and
  effect. The foregoing proxy is coupled with an interest sufficient in law to
  support an irrevocable power and shall be irrevocable and shall survive the
  liquidation, termination or dissolution of Assignor. Assignor hereby revokes
  any proxy or proxies heretofore given to any person or persons and agrees not
  to give any other proxies in derogation hereof until such time as this Agreement
  is no longer in full force and effect. 

 4.          REPRESENTATIONS,
  WARRANTIES, COVENANTS AND AGREEMENTS OF ASSIGNOR 

                Assignor
  hereby represents, warrants, covenants and agrees that: 

                4.1
           To the knowledge of Assignor,
  no act or event has occurred which would permit any party to assert a claim
  against the Collateral or which could materially adversely affect the Collateral.

                4.2
           Assignor will not take
  any action, which adversely affects the Collateral or Assignee’s interests
  in the Collateral.

                4.3
           Assignor will observe
  and comply with all terms of the Company’s Operating Agreement and pay

                4.4
           Assignor will promptly
  provide Assignee with copies of all material notices, correspondence, and information
  provided to the Company or its members. Without limiting the generality of the
  foregoing, this shall include offers and other documents pertaining to the sale
  of any of the assets of the Company and notices pertaining to any indebtedness
  of the Company. 

                4.5
           Assignor, at its cost
  and expense, shall protect and defend this Agreement, all of the rights of Assignee
  hereunder, and the Collateral against all claims and demands of other parties.
  Assignor shall pay all claims and charges that in the opinion of Assignee might
  prejudice, imperil or otherwise affect the Collateral or the Security Interest.
  Assignor shall promptly notify Assignee of any levy, distraint or other seizure
  by legal process or otherwise of any part of the Collateral and of any threatened
  or filed claims or proceedings that might in any way affect or impair the terms
  of this Agreement. 

                4.6
           The Security Interest,
  at all times, shall be perfected and shall be prior to any other interests in
  the Collateral. Assignor shall act and perform as necessary and shall execute
  and file all security agreements, financing statements, continuation statements
  and other documents requested by Assignee, and shall deliver to Assignee all
  documents and certificates

 requested by Assignee, to establish, maintain and continue
  the perfected Security Interest. Assignor, on demand, shall promptly pay all
  costs and expenses of filing and recording, including the costs of any searches,
  deemed necessary by Assignee from time to time to establish and determine the
  validity and the continuing priority of the Security Interest. 

                4.7
           If Assignor shall fail
  to pay any taxes, assessments, expenses or charges, Assignor agrees to keep
  all of the Collateral free from other security interests encumbrances or claims,
  or to perform otherwise as required herein, Assignee may advance the monies
  necessary to pay the same or to so perform. 

                4.8
           Assignor acknowledges
  that all rights, powers and remedies granted Assignee herein, or otherwise available
  to Assignee, are for the sole benefit and protection of Assignee, and Assignee
  may exercise any such right, power or remedy at its option and in its sole and

           Upon the occurrence of
  any Event of Default and at any time while such Event of Default is continuing,
  Assignee shall have the following rights and remedies and may do one or more
  of the following without further notice or demand: 

                               (a)
           Declare all or any part

  instructs the Company, upon receipt of notice from Assignee, to pay all distributions
  or profits of any nature on or related to the Collateral directly to Assignee
  at the address set forth in this Agreement, and the Company agrees to do the
  same. All such distributions and profits actually received by Assignee shall
  be credited to reduce the Obligation. Prior to the occurrence 

 -4- 

 of an Event of Default and after the cure of an Event of Default
  as permitted herein, subject to this Agreement, Assignor shall have the right
  to collect all profits and distributions associated with the Collateral. The
  receipt by Assignee of any profits or distributions shall not impose upon Assignee
  any of the obligations of Assignor with respect to the Collateral. 

                               (c)
            Pursue any right and/or
  any legal or equitable remedy available to Assignee, including, but not limited
  to, any right or remedy to collect the Obligation and/or to enforce its title
  in and right to possession of the Collateral. 

                               (d)
           After notice to Assignor
  as provided in Section 5.4 herein, sell such Collateral at public or private
  sale. The proceeds of such sale, after deducting therefrom all expenses of Assignee
  (including reasonable attorneys’ fees), shall be applied to the payment
  of the Obligation, and any surplus thereafter remaining shall be paid to Assignor
  or any other person that may be legally entitled thereto. In the event of a
  deficiency between such net proceeds from the sale of the Collateral and the
  total amount of the Obligation, Assignor, upon demand, shall promptly pay the
  amount of such deficiency to Assignee. 

                5.3
           Assignee, so far as may
  be lawful, may purchase all or any part of the Collateral offered at any public
  or private sale made in the enforcement of Assignee’s rights and remedies
  hereunder. 

                5.4
           Any demand or notice of
  sale, disposition or other intended action hereunder or in connection herewith,
  whether required by the Uniform Commercial Code or otherwise, shall be deemed
  to be commercially reasonable and effective if such demand or notice is given
  to Assignor at least 10 days prior to such sale, disposition or other intended
  action, in the manner provided herein for the giving of notices. 

                5.5
           All costs and expenses,
  including without limitation costs of Uniform Commercial Code searches, court
  costs and reasonable attorneys’ fees, incurred by Assignee in the preparation
  of this Agreement, the Purchase Agreement, the Promissory Note and the other
  documents executed in conjunction herewith, in enforcing payment and performance
  of the Obligation, and in exercising the rights and remedies of Assignee hereunder
  shall be the obligation of Assignor, and all such costs and expenses shall be
  secured by this Agreement and by all other lien and security documents securing
  the Obligation. In the event of any court proceedings, court costs and attorneys’
  fees shall be set by the court and not by jury and shall be included in any
  judgment obtained by Assignee. 

                5.6
           In addition to any remedies
  provided herein for an Event of Default, Assignee shall have all the rights
  and remedies afforded a secured party under the Uniform Commercial Code, all
  other legal and equitable remedies allowed under applicable law, and all other
  remedies provided for in any other documents securing or relating to the Obligation.
  No failure on the part of Assignee to exercise any of its rights hereunder arising
  upon any Event of Default shall be construed to prejudice its rights upon the
  occurrence of any other or subsequent Event of Default. No delay on the part
  of Assignee in exercising any such rights shall be construed to preclude it
  from the exercise thereof at any time while that Event of Default is continuing.
  Assignee may enforce any one or more rights or remedies hereunder successively
  or concurrently. By accepting payment or performance of any of the Obligation
  after its due date, Assignee shall not 

 -5- 

 thereby waive the agreement contained herein that time is
  of the essence, nor shall Assignee waive either its right to require prompt
  payment or performance when due of the remainder of the Obligation or its right
  to consider the failure to so pay or perform an Event of Default. 

                5.7
           If Assignor shall fail
  to pay any amount or to perform any obligation hereunder, Assignee may advance
  the monies necessary to pay or perform the same, and such advances shall bear
  interest at the rate set forth in the Promissory Note and shall become part
  of the Obligation secured hereby. 

 6.          MISCELLANEOUS
  PROVISIONS 

                6.1
           The acceptance of this
  Agreement by Assignee shall not be considered a waiver of or in any way to affect
  or impair any other security that Assignee may have, acquire simultaneously
  herewith, or hereafter acquire for the payment or performance of the Obligation,
  nor shall the taking by Assignee at any time of any such additional security
  be construed as a waiver of or in any way to affect or impair the Security Interest;
  Assignee may resort, for the payment or performance of the Obligation, to its
  several securities therefor in such order and manner as it may determine. 

                6.2
           Without notice or demand,
  without affecting the obligations of Assignor hereunder or the personal liability
  of any person for payment or performance of the Obligation, and without affecting
  the Security Interest or the priority thereof, Assignee, from time to time,
  may: (i) extend the time for payment of all or any part of the Obligation, accept
  a renewal note therefor, reduce the payments thereon, release any person liable
  for all or any part thereof, or otherwise change the terms of all or any part
  of the Obligation; (ii) take and hold other security for the payment or performance
  of the Obligation and enforce, exchange, substitute, subordinate, waive or release
  any such security; (iii) join in any extension or subordination agreement; or
  (iv) release any part of the Collateral from the Security Interest. 

                6.3
           Assignor waives and agrees
  not to assert: (i) any right to require Assignee to proceed against any guarantor,
  to proceed against or exhaust any other security for the Obligation, to pursue
  any other remedy available to Assignee, or to pursue any remedy in any particular
  order or manner; (ii) the benefits of any legal or equitable doctrine or principle
  of marshaling; (iii) the benefits of any statute of limitations affecting the
  enforcement hereof; (iv) demand, diligence, presentment for payment, protest
  and demand, and notice of extension, dishonor, protest, demand and nonpayment,
  relating to the Obligation; and (v) any benefit of, and any right to participate
  in, any other security now or hereafter held by Assignee. 

                6.4
           The terms herein shall
  have the meanings in and be construed under the Uniform Commercial Code. This
  Agreement shall be governed by and construed according to the substantive laws
  of the State of Arizona, without giving regard to conflict of law principles.
  Each provision of this Agreement shall be interpreted in such manner as to be
  effective and valid under applicable law, but if any provision of this Agreement
  is held to be void or invalid, the same shall not affect the remainder hereof
  which shall be effective as though the void or invalid provision had not been
  contained herein. 

 -6- 

                6.5
           No modification, rescission,
  waiver, release or amendment of any provision of this Agreement shall be made
  except by a written agreement executed by Assignor and a duly authorized officer
  of Assignee. 

                6.6
           This Agreement shall remain
  in full force and effect until all of the Obligation incurred before the receipt
  of such notice, and all of the Obligation incurred thereafter under commitments
  extended by Assignee before the receipt of such notice, shall have been paid
  and performed in full. 

                6.7
           No setoff or claim that
  Assignor now has or may in the future have against Assignee shall relieve Assignor
  from paying or performing the Obligation. 

                6.8
           Time is of the essence
  hereof. This Agreement shall be binding upon, and shall inure to the benefit
  of, the parties hereto and their heirs, personal representatives, successors
  and assigns. The term “Assignee” shall include not only the original
  Assignee hereunder but also any future owner and holder, including pledgees,
  of note or notes evidencing the Obligation. The provisions hereof shall apply
  to the parties according to the context thereof and without regard to the number
  or gender of words or expressions used. 

                6.9
           All notices required or
  permitted to be given hereunder shall be in writing and may be given in person

  a portion of Seller’s membership interest in the Company (collectively,
  the “Obligations”); and 

                WHEREAS,
  Guarantor will benefit from the transactions contemplated in the Purchase Documents
  and the Purchaser’s performance of the Obligations and is therefore willing
  to guarantee the full and complete payment and performance of each of the Obligations.

                NOW,
  THEREFORE, in consideration of the Obligations, and for other good and valuable
  consideration, the sufficiency of which is hereby acknowledged, Guarantor agrees
  as follows: 

                1.
                 Guarantor
  unconditionally and absolutely guarantees the full and prompt payment and performance
  of each of the Obligations when due, whether according to the present terms
  of the Obligations or any change or changes in the terms, covenants and conditions
  of any of the Obligations, now or at any time hereafter made or granted, or
  any earlier or accelerated date or dates for payment or performance of the agreements
  set forth in the Obligations; and agrees that Seller may at any time and without
  notice to Guarantor subordinate the indebtedness represented by the Obligations,
  or any part thereof, to any other obligation now or hereafter owed by the Purchaser
  to any other person without in any manner affecting the liability of Guarantor.
  It is understood that this Guaranty is a continuing guarantee of the payment
  and full performance of the Obligations, is not limited to a guarantee of collection
  of any amounts owing pursuant to the Obligations and shall remain in full force
  and effect until the termination of the Obligations. 

                2.
                 To
  the extent not prohibited by law, Guarantor expressly waives notice of the acceptance
  of this Guaranty, the creation of any present or future Obligations, nonpayment
  of any Obligations, proceedings to collect from the Purchaser or anyone else,

  Guarantor expressly consents to and waives notice of all of the above. 

                3.
                 Guarantor
  agrees that any rights Guarantor may have to payment and claims for reimbursement,
  subrogation, contribution or indemnification as a guarantor of the Obligations
  against either the Purchaser or any other guarantor of the Obligations shall
  not be enforced and no payment accepted until the Obligations have been paid
  in full and are not subject to any right of recovery, whether as preference
  in bankruptcy or otherwise. 

                4.
                 Guarantor
  agrees that Guarantor’s obligation to make payment in accordance with
  the terms of this Guaranty shall not be impaired, modified, changed, released
  or limited in any manner whatsoever in the event any portion of the Obligations
  are invalid or unenforceable against the Purchaser for any reason other than
  actual payment in full, or by any impairment, modification, change, release
  or limitations of the liability of the Purchaser or its estate in bankruptcy
  resulting from the operation of any present or future provision of the Federal
  Bankruptcy Code or other similar federal or state statute, or from the decision
  of any court. 

                5.
                 Guarantor
  agrees to pay all costs and expenses, including reasonable attorneys’
  fees incurred by Seller, its successors or assigns, in enforcing this Guaranty.

                6.               
  Guarantor agrees that this Guaranty shall inure to the benefit of Seller and
  may be enforced by Seller and any subsequent assignee or transferee of the Obligations,
  and shall be binding and enforceable upon Guarantor and Guarantor’s successors,
  assigns, executors and administrators. 

                7.
                 Guarantor
  agrees that all references in this Guaranty to Obligations of the Purchaser
  shall include any successor or assignee of the Purchaser so long as this Guaranty
  remains in effect. 

                8.
                 Guarantor
  agrees that this Guaranty shall be governed by the laws of the State of Arizona,
  other than its laws governing choice of law. 

                9.               If
  any term or provision of this Guaranty shall to any extent be invalid or unenforceable,
  the remainder of this Guaranty, or the application of any such term or provision
  other than those which are invalid or unenforceable, shall not be affected thereby,
  and each term and provision shall be valid and enforceable to the fullest extent
  permitted by law. 

                10.               Guarantor
  represents, warrants and covenants to Seller that, as of the date of this Guaranty:
  the fair salable value of Guarantor’s assets exceeds Guarantor’s
  liabilities including all contingent liabilities and Guarantor is meeting Guarantor’s
  current liabilities as they mature. Guarantor is fully aware of the financial
  condition of the Purchaser. Guarantor is delivering this Guaranty based solely
  upon Guarantor’s own independent investigation of the Purchaser and the

 2 

 Obligations secured by this Guaranty and in no part upon any
  representation or statement of Seller with respect thereto. Guarantor is in
  a position to and hereby assumes full responsibility for obtaining any additional
  information concerning the Purchaser’s financial condition as Guarantor
  may deem material to Guarantor’s obligations hereunder and Guarantor is
  neither relying upon nor expecting Seller to furnish Guarantor any information
  in Seller’s possession concerning the Purchaser’s financial condition.

                11.               Guarantor
  is a corporation, validly existing and in good standing under the laws of the
  State of Oregon, and Guarantor has full power and authority to execute and deliver
  this Guaranty and to perform its obligations hereunder. This Guaranty is a binding
  obligation of Guarantor enforceable against Guarantor in accordance with its
  terms. 

                12.               This
  Guaranty constitutes the entire agreement of Guarantor with Seller with respect
  to the subject matter hereof and may not be amended, modified or changed in
  any manner without the prior written consent of Seller. 

                13.               Guarantor
  has carefully read each Purchase Document and the representations, warranties,
  covenants and agreements attributable to Guarantor therein, each such representation,
  warranty, covenant and agreement is hereby incorporated herein and is, as to
  such representations and warranties, true and correct as of the date hereof,
  and as to such agreements and covenants, binding upon Guarantor. 

                14.               Guarantor
  agrees that, if at any time all or any part of any payment theretofore applied
  by Seller to any of the Obligations is or must be rescinded or returned by Seller
  for any reason whatsoever (including, without limitation, the insolvency, bankruptcy
  or reorganization of the Purchaser), such Obligations shall, for the purposes
  of this Guaranty, to the extent that such payment is or must be rescinded or
  returned, be deemed to have continued in existence, notwithstanding such application
  by Seller, and this Guaranty shall continue to be effective or be reinstated,
  as the case may be, as to such Obligations, all as though such application by
  Seller had not been made. 

                15.               Guarantor
  represents and warrants that the obligations hereunder are undertaken for a
  corporate purpose and are in the interest of Guarantor.

  to those Members shall be specially allocated among the other Members in the
  ratio that each shares in Losses. If any Losses are allocated to an Member under

  Special Allocations. The following special allocations shall be made
  in the following order: 

                               (a)               
  Minimum Gain Chargeback. Except as otherwise provided in Regulation Section
  1.704 -2(f), notwithstanding any other provision of this Article 3, if there
  is a net decrease 

 11

 in Company Minimum Gain during any Fiscal Year, each Member
  shall be specially allocated items of Company income and gain for such Fiscal
  Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such
  Person's share of the net decrease in Company Minimum Gain, determined in accordance
  with Regulations Section 1.704 -2(g). Allocations pursuant to the previous sentence
  shall be made in proportion to the respective amounts required to be allocated
  to each Member pursuant thereto. The items to be so allocated shall be determined
  in accordance with Regulation Sections 1.704 -2(f)(6) and 1.704 -2(j)(2). This
  Section 3.5(a) is intended to comply with the minimum gain chargeback requirement
  in Regulation Section 1.704 -2(f) and shall be interpreted consistently therewith.

  Section 1.704 -2(i)(4), notwithstanding any other provision of this Article

  of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse
  Debt, determined in accordance with Regulation Section 1.704 -2(i)(5), shall
  be specially allocated items of Company income and gain for such Fiscal Year
  (and, if necessary, subsequent Fiscal Years) in an amount equal to such Person's
  share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable
  to such Member Nonrecourse Debt, determined in accordance with Regulations Section
  1.704 -2(i)(4). Allocations pursuant to the previous sentence shall be made
  in proportion to the respective amounts required to be allocated to each Member
  pursuant thereto. The items to be so allocated shall be determined in accordance
  with Regulation Sections 1.704 -2(i)(4) and 1.704 -2(j)(2). This Section 3.5(b)
  is intended to comply with the minimum gain chargeback requirement in Regulation
  Section 1.704 -2(i)(4) and shall be interpreted consistently therewith. 

                               (c)               
  Qualified Income Offset. In the event any Member unexpectedly receives
  any adjustments, allocations, or distributions described in Regulation Section
  1.704 -1(b)(2)(ii)(d)(4), Section 1.704 -1(b)(2)(ii)(d)(5) or Section 1.704
  -1(b)(2)(ii)(d)(6), items of Company income and gain shall be specially allocated
  to each such Member in an amount and manner sufficient to eliminate, to the
  extent required by the Regulations, the Adjusted Capital Account Deficit of
  such Member as quickly as possible, provided that an allocation pursuant to
  this Section 3.6(c) shall be made only if and to the extent that such Member
  would have an Adjusted Capital Account Deficit after all other allocations provided
  for in this Article 3 have been tentatively made as if this Section 3.5(c) were
  not in the Agreement. 

                               (d)               
  Gross Income Allocation. In the event any Member has a deficit Capital
  Account at the end of any Fiscal Year which is in excess of the sum of (i) the
  amount such Member is obligated to restore pursuant to any provision of this
  Agreement, and (ii) the amount such Member is deemed to be obligated to restore
  pursuant to the penultimate sentences of Regulations Sections 1.704 -2(g)(1)
  and 1.704 -2(i)(5), each such Member shall be specially allocated items of Company
  income and gain in the amount of such excess as quickly as possible, provided
  that an allocation pursuant to this Section 3.6(d) shall be made only if and
  to the extent that such Member would have a deficit Capital Account in excess
  of such sum after all other allocations provided for in this Article 3 have
  been made as if Section 3.5(c) and this Section 3.5(d) were not in the Agreement.

                               (e)               
  Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall
  be specially allocated to the Members in proportion to their respective Percentage
  Membership Interests. 

                               (f)               
  Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for
  any Fiscal Year shall be specially allocated to the Member who bears the economic
  risk of loss with respect to the Member Nonrecourse Debt to which such Member
  Nonrecourse Deductions are attributable in accordance with Regulations Section
  1.7042(i)(1) . 

                               (g)               
  Section 754 Adjustments. Any voluntary elections under Code Section 754
  shall be made by the Managers. To the extent an adjustment to the adjusted tax
  basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b)
  is required, pursuant to Regulations Section 1.7041(b)(2)(iv)(m)(2) or Regulations
  Section 1.704 -1(b)(2)(iv)(m)(4), to be taken into account in determining Capital
  Accounts as the result of a distribution to a Member in complete liquidation
  of his Membership Interest, the amount of such adjustment to Capital Accounts
  shall be treated as an item of gain (if the adjustment increases the basis of
  the asset) or loss (if the adjustment decreases such basis) and such gain or
  loss shall be specially allocated to the Members in accordance with their interests
  in the Company in the event that Regulations Section 1.704 -1(b)(2)(iv)(m)(2)
  applies, or to the Member to whom such distribution was made in the event that
  Regulations Section 1.704 -1(b)(2)(iv)(m)(4) applies. 

                               (h)               
  Allocations Relating to Taxable Issuance of Membership Interests. Any
  income, gain, loss or deduction realized as a direct or indirect result of the
  issuance of an interest by the Company to a Member (the "Issuance Items")
  shall be allocated among the Members so that, to the extent possible, the net
  amount of such Issuance Items, together with all other allocations under this
  Agreement to each Member, shall be equal to the net amount that would have been
  allocated to each such Member if the Issuance Items had not been realized. 

                3.6          
  Curative Allocations. The allocations set forth in Section 3.4(a) and
  Sections 3.5(a), 3.5(b), 3.5(c), 3.5(d), 3.5(e), 3.5(f), and 3.5(g) (the "Regulatory
  Allocations") are intended to comply with certain requirements of the Regulations.
  It is the intent of the Members that, to the extent possible, all Regulatory
  Allocations shall be offset either with other Regulatory Allocations or with
  special allocations of other items of Company income, gain, loss or deduction
  pursuant to this Section 3.6. Therefore, notwithstanding any other provision
  of this Article 3 (other than the Regulatory Allocations), the Manager shall
  make such offsetting special allocations of Company income, gain, loss or deduction
  in whatever manner it determines appropriate so that, after such offsetting
  allocations are made, each Member's Capital Account balance is, to the extent
  possible, equal to the Capital Account balance such Member would have had if
  the Regulatory Allocations were not part of the Agreement and all Company items
  were allocated pursuant to Sections 3.2, 3.3 and 3.5(h) . 

                3.7          
  Other Allocation Rules.

  any period, Profits, Losses, and any such other items shall be determined on
  a daily, monthly, or other basis, as determined by the Manager using any permissible
  method under Code Section 706 and the Regulations thereunder. 

 13

                               (b)
                 The
  Members are aware of the income tax consequences of the allocations made by
  this Article 3 and hereby agree to be bound by the provisions of this Article
  3 in reporting their shares of Company income and loss for income tax purposes,
  except to the extent otherwise required by law. 

                               (c)

  for purposes of determining a Member's or Member's proportionate share of the
  "excess nonrecourse liabilities" of the Company within the meaning of Regulations
  Section 1.752 -3(a)(3), the Members' interests in Company profits are in proportion
  to their Percentage Membership Interests. 

                3.8          
  Tax Allocations: Contributed Property. In accordance with Code Section
  704(c) and the Regulations thereunder, income, gain, loss, and deduction with
  respect to any property contributed to the capital of the Company shall, solely
  for tax purposes, be allocated among the Members so as to take account of any
  variation between the adjusted basis of such property to the Company for federal
  income tax purposes and its initial Gross Asset Value (computed in accordance
  with subparagraph (i) of the definition of "Gross Asset Value." In the event
  the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph
  (ii) of the definition of "Gross Asset Value," subsequent allocations of income,
  gain, loss, and deduction with respect to such asset shall take account of any
  variation between the adjusted basis of such asset for federal income tax purposes
  and its Gross Asset Value in the same manner as under Code Section 704(c) and
  the Regulations thereunder. Any elections or other decisions relating to such
  allocations shall be made by the Manager in any manner that reasonably reflects
  the purpose and intention of this Agreement, provided that the Company shall
  elect to apply the allocation method permitted by the Regulations under Code
  Section 704(c) that is reasonably selected by the Managers. Allocations pursuant
  to this Section 3.8 are solely for purposes of federal, state, and local taxes
  and shall not affect, or in any way be taken into account in computing, any
  Person's Capital Account or share of Profits, Losses, other items, or distributions
  pursuant to any provision of this Agreement. Except as otherwise provided in
  this Agreement, all items of Company income, gain, loss, deduction, and any
  other allocations not otherwise provided for shall be divided among the Members
  in the same proportions as they share Profits or Losses, as the case may be,
  for the Fiscal Year. 

                3.9          
  Managers' Discretion Regarding Elections. Any elections or other decisions
  relating to the allocations under this Agreement, the maintenance of the Members'
  Capital Accounts or any other elections provided for in the Code or other applicable
  law shall be made by the Manager in any manner that reasonably reflects the
  purpose and intention of this Agreement. The Members acknowledge, by signing
  this Agreement that they are aware of the income tax consequences of the allocations
  made herein and the economic impact of the allocations on the amounts receivable
  by them under the Agreement. The Members hereby agree to report their respective
  shares of the Company's income and loss for income tax purposes, consistent
  with the terms and provisions of this Agreement.

                 For
  purposes of this Agreement, the "Time Period" shall be such time period during
  which a Person is a Member or Manager and THEREAFTER for a period of 12 months,
  provided that if, but only if, a court or other tribunal of final authority

  or other tribunal of final authority concludes that the 

 22

 period of 9 months is unenforceable because it is unreasonably
  long, then for a period of 6 months, provided that if, but only if, a court
  or other tribunal of final authority concludes that the period of 6 months is

  its Business, provided that if, but only if, a court or other tribunal of final
  authority concludes that the area including each state of the United States
  of America in which the Company has conducted its Business is unenforceable
  because it is unreasonably large, then the Geographic Scope shall be each county
  of the United States of American in which the Company has conducted its Business.

                               (c)               
  Remedies. Each Member and Manager agrees that his failure to strictly
  adhere to this Section 6.14 is likely to result in substantial injury to the
  Company, that damages would be difficult to measure, and the injury to the Company
  would be irreparable, for which money damages would be an inadequate remedy.
  Therefore, in addition to all other remedies the Company may be entitled to,
  the Company shall be entitled to specific performance and other equitable relief,
  including temporary and permanent injunctive relief, to enforce this Section
  6.4 and such other remedies set forth in this Agreement. 

                               (d)               
  Severability. If, but only if, a court or other tribunal of final authority
  concludes that any term or provision of this Section 6.14 is invalid or unenforceable,
  the parties hereto agree that the court or other tribunal of final authority
  making the determination of invalidity or unenforceability shall have the power
  to reduce the scope, duration, or area of the term or provision, to delete specific
  words or phrases, or to replace any invalid or unenforceable term or provision
  with a term or provision that is valid and enforceable and that comes closest
  to expressing the intention of the invalid or unenforceable term or provision,
  and this Agreement shall be enforceable as so modified after the expiration
  of the time within which the judgment may be appealed.

                7.6          
  Tax Controversies. The Members shall notify each other of all administrative
  and judicial federal and state tax proceedings relating to the Company. The
  Tax Matters Member shall have the right to obtain professional assistance with
  respect to any audit of the Company. Expenses of any proceedings undertaken
  by the Tax Matters Member shall be paid by the Company. The cost of any adjustment
  to a Member, and the cost of any resulting audits or adjustments to a Member's
  tax return, shall be borne solely by the affected Member. The Tax Matters Member
  shall act as such for the Company and the Members, with all the rights and responsibilities
  of that position described in the Code, while keeping the other Members fully
  informed. No other Member shall have the right to act for the Company, or for
  itself or for any other Member with respect to any Company tax issues. Without
  the consent of a Super Majority in Interest of the Members, the Tax Matters
  Member shall not settle, defend or refuse to settle any material tax issues
  raised by any authority with respect to items of income, gain, loss, deduction
  and credit relating to the Company, its property or business.

  Purchase Agreement), or the Option Agreement where such failure continues for
  thirty (30) days after Notice of such default is given by the Non-Defaulting
  Member, except that if the default is a non-monetary default and cannot reasonably
  and with due diligence and in good faith be cured within the thirty (30) day
  period, and if the Defaulting Member immediately commences and proceeds to complete
  the cure of such default with due diligence and in good faith, the thirty (30)
  day period with respect to such default shall be extended to include such additional
  period of time as may be reasonably necessary to cure such default. 

                8.2

  then the following shall be true: 

                               (a)

                 Except

 ARTICLE 9 

  TRANSFERS, WITHDRAWALS 

 25

                9.1          
  Restriction on Transfers. Except as otherwise expressly provided in this
  Agreement or the Option Agreement or the Security Agreement (as defined in the
  Purchase Agreement), no Membership Interest may be Transferred without the written
  consent of a Super Majority in Interest of the Members, which consent may be
  withheld or conditioned in the sole and absolute discretion of each Member.
  A Member's request for consent to Transfer its Membership Interest must identify
  the proposed transferee, describe in detail the terms and conditions of the
  proposed Transfer, and describe any additional information the non-Transferring
  Member reasonably requests regarding the proposed Transfer or the proposed transferee.
  The non-Transferring Member shall notify the Transferring Member of its election
  to consent or withhold consent within fifteen (15) days of its receipt of the
  Transferring Member's written request for such consent. If the non-Transferring
  Member consents to the Transfer, the non-Transferring Member may impose on the
  Transferring Member or the transferee such conditions as the non-Transferring
  Member, in its reasonable discretion, deems appropriate. Any attempted Transfer
  without such written consent, other than a Transfer permitted by this Agreement,
  shall be null and void and of no force and effect. A Transferee may only be
  admitted as a Substitute Member pursuant to Section 9.6 below.

                9.2          
  Withdrawal of a Member. Except as otherwise provided in this Agreement,
  no Member shall have the right or power to withdraw from the Company. In the
  event a Member withdraws from the Company in violation of this Agreement and
  the business of the Company is continued, such withdrawing Member shall not
  be entitled to a return of its Capital Contributions nor receive any payment
  for its Membership Interest until the Company is dissolved pursuant to Section
  10.1. Instead, such Member shall have the status of an Assignee. Furthermore,
  any such withdrawal shall constitute a material breach of this Agreement and
  the Company shall have the right to recover damages from the withdrawn Member
  and to offset the damages against any amounts otherwise distributable to such
  Member under this Agreement. 

                9.3          
  Option on Certain Events.

                               (a)
                 The
  events set forth in Section 9.3(b) shall constitute a deemed offer (a "Deemed
  Offer") by a Member or the Member's legal representative (in either case,
  the "Deemed Offeror") to sell of its Membership Interest (the
  "Deemed Offered Interest"), and upon the occurrence of any of the following
  events, the Company and the other Member (the "Remaining Member")
  (each a "Deemed Offeree") shall have the right to purchase the Deemed
  Offered Interest, or any portion thereof, pursuant to the ordering and timing
  provisions set forth below.

                               (b)
                 For
  purposes of this Section 9.3, events resulting in a Deemed Offer by a Member
  shall include each of the following: 

                                                 (i)
                 The
  occurrence of such Member's dissolution or similar event described in Section
  29-733(b) through (11) of the Act (whether voluntary or involuntary); 

                                                 (ii)
                 Such
  Member's withdrawal or attempted withdrawal from the Company;

                                                 (iii)
                With
  respect to Diagnostic only, if the Company does not timely satisfy the Benchmarks;

 26

                                                 (iv)
                 Such
  Member's Event of Default; and 

                                                 (v)
                 Any
  voluntary or involuntary Transfer of Membership Interest by such Member not
  otherwise covered by this Agreement.

                               (c)
                Upon
  the occurrence of an event giving rise to a Deemed Offer, then the Deemed Offeror
  shall offer, or shall automatically be deemed to have offered, to sell the Deemed
  Offered Interest to the Company and the Remaining Member. The Company shall
  have the right and option, within one hundred twenty (120) days (or, in the
  case of the circumstances described in Section 9.3(b)(iii), at any time), (the
  "Company Offer Period") after its actual knowledge of the event giving
  rise to the Deemed Offer event to accept the Deemed Offer and acquire the Deemed
  Offered Interest for the purchase price and on the terms set forth in Exhibit
  C. If the Deemed Offered Interest is not purchased by the Company within
  the Company Offer Period (or, in the case of the circumstances described in
  Section 9.3(b)(iii), if the Company waives its right), then the Remaining Member
  shall have the right and option, within sixty (60) days after the expiration
  of such Company Offer Period (or waiver, as the case may be), to elect to acquire
  the Deemed Offered Interest for the purchase price and on the terms set forth
  in Exhibit C. In the event a Deemed Offeree accepts such offer to purchase,
  it shall so notify the Deemed Offeror in writing and shall designate the date,
  not more than ninety (90) days following the date of such notice, and the time
  and place where such sale shall be completed.

                               (d)
                 If
  the Deemed Offered Interest is not purchased by the Deemed Offerees pursuant
  to Section 9.3(c), the Deemed Offered Interest may be retained by the Deemed
  Offeror or shall be Transferred to the Deemed Offeror's successor-in-interest,
  as the case may be, but in either case, the holder of such Deemed Offered Interest
  shall remain fully subject to and bound by the terms of this Agreement. Unless
  and until admitted as a substitute Member pursuant to Section 9.6, a transferee
  of a Member's Membership Interest in whole or in part who is not already a Member
  shall be an Assignee with respect to such Membership Interest. 

                9.4          
  Right of First Refusal. 

                               (a)
                 In
  the event any Member (a "Selling Member") receives a bona fide written
  offer (the "Sale Offer") from any Person (other than a Member or an Affiliate
  of a Member) to purchase all or any portion of such Selling Member's Membership
  Interest (the "Sale Interest") for a purchase price denominated
  and payable in United States dollars, then the Selling Member shall first, prior
  to accepting such Sale Offer, provide to the other Member (the "non-Selling
  Member") Notice (an "Offering Notice") specifying in detail the price,
  terms and conditions of the Sale Offer along with the name of the proposed purchaser
  (such proposed purchaser being a fully disclosed principal) together with a
  complete copy of such Sale Offer. The non-Selling Member shall have an obligation
  to keep such Sale Offer confidential and shall not have the right to contact
  the Person making the Sale Offer until such Sale Offer is either accepted or
  deemed rejected pursuant to this Section 9.4. 

                               (b)
                 The
  non-Selling Member shall have the right, irrevocable for a period of ninety
  (90) days after receipt of the Offering Notice (the "Member Offer Period")
  to purchase the Sale Interest at the price and upon the terms set forth in the
  Sale Offer; subject, however, to the modifications set forth in this Section
  9.4. The non-Selling Member may not elect to purchase 

 27

 less than all of the Sale Interest. If the non-Selling Member
  does not timely accept the Sale Offer and elect to purchase such Sale Interest
  within the ninety (90) day period described above and consummate the purchase
  as set forth below, the Sale Offer set forth in the Offering Notice shall be
  deemed rejected as to all of the Sale Interest and for a period of thirty (30)
  days after the Sale Offer is so rejected, the Selling Member shall be free to
  dispose of the Sale Interest at (but only at) the price and on (but only on)
  the terms and conditions of the Sale Offer set forth in the Offering Notice.
  Such disposal shall be subject, however, to the provisions set forth in Section
  9.4 below. 

                               (c)
                 Subject
  to the provisions of Section 9.4(d) below, the non-Selling Member may purchase
  all and not less than all of the Sale Interest upon the terms and conditions
  set forth in the Offering Notice; provided, however, that the Transfer from
  the Selling Member to the non-Selling Member shall be consummated on a date
  not more than one hundred twenty (120) days after the non-Selling Member notifies
  the Selling Member of its desire to purchase the Sale Interest.

                               (d)
                 In
  the event the non-Selling Member elects to purchase the Sale Interest and does
  not timely consummate the purchase of the Sale Interest pursuant to this Section
  9.4, the Selling Member shall thereafter have the right to Transfer such Sale
  Interest to any Person making a bona fide offer for such Sale Interest
  without first having to offer such to the non-Selling Member pursuant to this
  Section 9.4 subject, however, to the provisions set forth in Section 9.5. 

                               (e)
                 Except
  as provided in Section 9.4(d), if the Selling Member does not timely Transfer
  the Sale Interest within the thirty (30) day period following the non-Selling
  Member's rejection of the Sale Offer, the rights of the non-Selling Member as
  set forth in this Section 9.4 shall again apply to any subsequent Transfer of
  all or any portion of the Selling Member's Membership Interest. 

                9.5          
  Conditions Precedent. As a condition to recognizing one or more of the
  effectiveness and binding nature of any Transfer of Membership Interest and
  after satisfying the other restrictions contained in Article 9, a Transfer of
  all or any portion of or any interest or rights in a Membership Interest shall
  only be effective if the following conditions are satisfied: 

                               (a)
                 A
  duly executed and acknowledged written instrument of assignment is filed with
  the Company; 

                               (b)
                 The
  transferee agrees to be bound by the terms and conditions of this Agreement,
  including without limitation the provisions of this Article 9 (regardless of
  whether such Person is to be admitted as a new Member);

                               (c)
                 The
  Transfer will not cause a termination of the Company under Code Section 708;
  provided, however, that the requirement of this Section 9.5(c) shall be waived
  if the Managers reasonably determine that such termination will not have a material
  adverse effect on the Company or the Members; 

                               (d)
                 Each
  Member consents (which consent may be unreasonably or arbitrarily withheld)
  in writing to such Transfer; and

 28

                               (e)
                 The
  Managers are reasonably satisfied that after the completion of such Transfer:
  the Company will remain qualified to do business in each jurisdiction in which
  the Company is qualified, organized or does business; the Company will maintain
  its status as a partnership for federal and applicable state tax purposes; and
  such Transfer will comply with any applicable state and federal laws including,
  without limitation, all securities and healthcare laws and regulations. 

                9.6         
  Requirements To Become a Substituted Member. No transferee of a Membership
  Interest shall become a Member in the Company unless and until the following
  conditions are satisfied: 

                               (a)
                 Each
  Members in its sole and absolute discretion, consents to such transferee being
  admitted as a Member; 

                               (b)
                 All
  expenses of the Company incurred in connection with the Transfer shall have
  been paid by or for the account of such transferee; and 

                               (c)
                 All
  agreements, articles, minutes, written consents, and other necessary documents
  and instruments shall have been executed and filed and all other acts shall
  have been performed which are necessary to make the transferee a Member of the
  Company. 

                9.7          
  Assignees. An Assignee shall be entitled to receive allocations of Profits
  and Losses and distributions of Net Cash Flow from the Company attributable
  to the Membership Interest held by such Assignee; provided, however, that such
  Assignee shall have no right to inspect the Company books or records, to vote
  on Company matters, or to exercise any other right or privilege as a member
  of the Company. Further, any Member Transferring its Membership Interest may
  not, as a condition of such Transfer, agree or obligate itself to act on behalf
  of or under the direction of such Assignee with regard to any right or privilege
  which a Member would have with respect to such Transferred Membership Interest
  and any attempts to act in such capacity shall be void and of no effect and
  shall not be recognized by the Company. An Assignee shall only become a Member
  of the Company pursuant to Section 9.6. 

 ARTICLE 10

                               (a)
                 The
  written consent of all of the Members;

                               (b)

                10.2         
  Filing Upon Dissolution. As soon as possible following the dissolution
  of the Company, the Managers shall execute and file a Notice of Winding Up with
  the Arizona

  by a court of competent jurisdiction. 

                10.3

  as required by applicable law; 

                               (b)
                 Second,
  to creditors who are Members; 

                               (c)
                 Third,

  discretion; and 

                               (d)

  liable for a deficit Capital Account balance of that Member, it being expressly
  understood that the distribution of liquidation proceeds shall be made solely
  from existing Company assets in the order of priority described in Section 10.3.
  Except as otherwise provided in this Agreement, if the Company assets remaining
  after the payment or discharge of the debts and liabilities of the Company is

                10.5         
  Rights of Members' Distributions of Property. Except as otherwise provided
  in this Agreement, each Member shall look solely to the assets of the Company
  for the return of its Capital Contributions and shall have no right or power
  to demand or receive property other than cash from the Company. 

                10.6         
  Reasonable Time for Winding Up. A reasonable time shall be allowed for
  the orderly winding up of the business and affairs of the Company and the liquidation
  of its assets in order to minimize any losses otherwise related to that winding
  up.

                               (c)               THE
  PARTIES AGREE THAT IN ORDER TO PROMOTE TO THE  FULLEST  EXTENT 
  REASONABLY  POSSIBLE  A  MUTUALLY  AMICABLE  RESOLUTION
  OF THE DISPUTE IN A TIMELY, EFFICIENT AND COST-EFFECTIVE  MANNER, THEY
  WILL WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY  AND SETTLE THEIR
  DISPUTE BY SUBMITTING THE CONTROVERSY TO  ARBITRATION IN ACCORDANCE WITH
  THE COMMERCIAL RULES OF THE  AMERICAN ARBITRATION ASSOCIATION (A.A.A.)
  EXCEPT THAT ALL PARTIES  SHALL BE ENTITLED TO ALL DISCOVERY RIGHTS ALLOWED
  UNDER THE ARIZONA RULES OF CIVIL PROCEDURE. 

                               (d)               The
  Parties shall attempt to select a mutually agreeable arbitrator. If no 
  agreement is reached within ten (10) days of the Notice of Arbitration, then
  either Party may  apply to the current Director of Professional Services
  for A.A.A. in Arizona requesting that he  appoint an arbitrator from the
  A.A.A.'s Panel of Arbitrators who has substantial experience in the  matters
  at issue. In either case, it shall be a condition of such appointment that the
  arbitrator can  conduct all proceedings and render a decision within sixty
  (60) days after such appointment. 

                               (e)               The
  Arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. 
  §1 et seq., and the judgment upon the award rendered by the arbitrator
  may be entered by any  court having jurisdiction thereof. Either Party
  may elect to participate in the arbitration  telephonically. Any substantive
  or procedural rights other than the enforceability of the  

31

 arbitration agreement shall be governed by Arizona law, without
  regards to Arizona's conflict of laws principles. 

                               (f)
                 The
  Parties further expressly agree that (i) the arbitrator shall only reach his
  or her decision by applying strict rules of law to the facts, (ii) the arbitration
  shall be conducted in the English language, in Maricopa County, Arizona, (iii)
  the Party in whose favor the arbitration award is rendered shall be entitled
  to recover costs and expenses of the arbitration including, but not limited
  to, attorneys' fees and the cost and expense of administration of the arbitration
  proceedings, and any costs and attorney's fees incurred in executing on or enforcing
  the arbitration award or, if the decision is not clearly in favor of one Party
  or other, such costs and expenses shall be borne as determined by the arbitrator,
  and (iv) the arbitral award shall be issued in Maricopa County, Arizona, U.S.A.

                               (g)
                 Except
  as provided in the following sentences, no Party shall be entitled to commence
  or maintain any action in a court of law upon any matter in dispute until such
  matter shall have been submitted and determined as provided herein and then
  only for the enforcement of such arbitration award. Provided that, notwithstanding
  this dispute resolution policy, either Party may apply to a court of competent
  jurisdiction in Maricopa County, Arizona, to seek injunctive relief before or
  after the pendency of any arbitration proceeding. The institution of any action
  for injunctive relief shall not constitute a waiver of the right or obligation
  of any party to submit any claim seeking relief other than injunctive relief
  to arbitration. Judgment upon the award may be entered by the United States
  Federal District Court or Maricopa County Superior Court located in the State
  of Arizona, or application may be made to such court for the judicial acceptance
  of the award and order of enforcement, as the case may be, if the Arbitrator's
  award or decision is not complied with within seven (7) days of the Arbitrator's
  decision. 

                               (h)
                 Arbitration
  shall be the sole and exclusive procedure for resolution of disputes between
  the parties, including any disputes that might arise after termination of this
  Agreement. 

                11.3         
  Attorney's Fees. If any party institutes suit or arbitration against
  any other party to enforce or interpret the terms of this Agreement, the prevailing
  party shall be entitled to taxable and non-taxable costs, consultant and expert
  witness fees, pre-judgment and post-judgment interest, and reasonable attorneys'
  fees and disbursements of counsel incurred as a result of such action.

 EXHIBIT C 

 PURCHASE PROCEDURES 

                When
  required pursuant to Section 9.3 of this Agreement, the purchase of a Membership
  Interest shall be made as follows: 

                1.            
  Purchase Price. In the event the Company or a Member exercises an option
  to purchase a Membership Interest (the "Sale Interest") pursuant to Section
  9.3 of this Agreement, the purchase price (the "Purchase Price") for
  the Sale Interest shall be the Fair Market Value of the Sale Interest as determined
  below.

                               (a)
                 Except
  as otherwise provided above, the Fair Market Value of the Sale Interest shall
  be such amount that is agreed upon by the buyer (the "Buyer") and the
  seller (the "Seller") of such Sale Interest. If such parties are not
  able to reasonably agree on such amount, then one or more Qualified Appraisers
  selected under the procedures set forth in this Paragraph 1 shall determine
  such amount. For purposes of this Paragraph 1, a "Qualified Appraiser" shall
  mean a professional appraiser or other qualified valuation expert who is qualified
  by experience and ability to appraise the fair market value of the Sale Interest.
  The appointment of a Qualified Appraiser shall be made by a written instrument
  delivered to the Buyer and the Seller. 

                               (b)
                 The
  Seller shall have the opportunity to appoint one Qualified Appraiser at its
  expense within twenty (20) days following its receipt of written notice from
  the Buyer of Buyer's intent to purchase the Sale Interest. The Buyer shall have
  the opportunity to appoint one Qualified Appraiser at its own expense within
  twenty (20) days of the Seller's receipt of such written notice. If either the
  Seller or the Buyer fails to appoint a Qualified Appraiser within such twenty
  (20) day period, the selected Qualified Appraiser shall unilaterally establish
  the Fair Market Value of the Sale Interest by a written option. 

                               (c)
                 If
  two Qualified Appraisers shall have been timely appointed, these two Qualified
  Appraisers shall establish the Fair Market Value of the Sale Interest in a single
  written opinion agreed to by both of them. If such two Qualified Appraisers
  cannot agree on the Fair Market Value of the Sale Interest within sixty (60)
  days of the appointment of the later of them, they shall each prepare an independent
  appraisal within such sixty (60) day period, and the average of the Fair Market
  Value determined under these two appraisals shall be the Fair Market Value of
  the Sale Interest. 

                2.            
  Payment of Purchase Price. Unless otherwise agreed upon by the parties
  involved in the Transfer of such Sale Interest, the Buyer of such Sale Interest
  shall pay the Purchase Price as follows: 

                               (a)
                 The
  Purchase Price shall be paid to the Seller as follows: ten percent (10%) of
  such Purchase Price (the "Down Payment"), shall be paid to the Seller
  in full on the date such Transfer of the Sale Interest (the "Closing Date")
  by bank cashier’s or certified check; and (ii) the balance of such Purchase
  Price shall be evidenced by a promissory note, dated as of the Closing Date,
  from the Buyer to the Seller providing for principal to be paid in twenty (20)
  consecutive equal quarterly installments, commencing three months from the Closing
  Date, and 

 40

 for accrued interest to be payable on each principal installment
  date. The interest rate payable on the unpaid balance of the promissory note
  shall be an annual rate equal to the Prime Rate in effect on the Closing Date
  (or the first banking day immediately after such Closing Date if such Closing
  Date occurs on a date that is not a banking day in the state of Arizona) plus
  1%. The Buyer shall have the right to prepay the promissory note, in whole or
  in part, from time to time, without penalty. 

                               (b)               
  In the event the Company is the Buyer hereunder, then at the election of the
  Company made in its sole discretion, the Purchase Price due by the Company hereunder
  to the Seller in return for the Sale Interest may be reduced in whole or in
  part at such time or time as the Company may elect in the amount of (or any
  portion of the amount of) any indebtedness of the Seller to the Company. 

                3.            
  Place of Closing. The closing shall take place at the principal office
  of the Company or at such other place as the parties thereto shall otherwise
  agree.

                4.            
  Delivery of Documents. On or before the Closing Date, the Seller, or
  its legal representative, shall deliver to the Buyer in exchange for the portion
  of the Purchase Price due as of the Closing Date, the certificate(s), if any,
  representing the Sale Interest, duly endorsed for transfer and a representative
  that such Sale Interest is being Transferred free and clear of all liens, claims,
  or encumbrances.

                 The
  following opinions shall be reflected in the opinion of Purchaser’s /
  Parent’s counsel in substantially the form provided below and subject
  to reasonable qualifications, assumptions, and limitations set forth therein.
  Capitalized terms used but not otherwise defined in the opinion will have the
  meanings ascribed to such terms in the Limited Liability Company Membership
  Purchase Agreement (the “Purchase Agreement”).

                1.
              Purchaser
  and Parent are corporations validly existing and in good standing under the
  laws of the jurisdiction of their respective organizations. 

                2.
              Purchaser
  is duly qualified as a foreign corporation in each of [jurisdictions to be
  inserted]. 

                3.
              Parent
  is duly qualified as a foreign corporation in each of [jurisdictions to be
  inserted]. 

                4.
              Purchaser
  and Parent have the requisite corporate power and corporate authority to own
  their respective assets and properties and to conduct their respective businesses
  as presently conducted.

                5.
              The
  entire authorized capital stock of Purchaser consists of: (i) ___________ shares
  of Common Stock, par value of $___ per share, of which _____ shares are
  issued and outstanding; (ii) ___________ shares of _______________ , par value
  of $ _____ per share, of which _________ shares are issued and outstanding;
  and (iii) ___________ shares of ________________ Preferred Stock, par value

  of which _________ shares are issued and outstanding; and (iii) ___________
  shares of ________________ Preferred Stock, par value $____ per share, of
  which no shares are issued and outstanding. 

                7.
              The
  Delivered Parent Shares have been duly authorized, validly issued and
  are fully paid and nonassessable. 

                8.
              Purchaser
  and Parent have the corporate power to execute, deliver and perform the Transaction
  Agreements and have taken all necessary corporate action to authorize the execution,
  delivery and performance of the Transaction Agreements. 

                9.
              Purchaser
  and Parent have duly executed and delivered the Transaction Agreements and each
  Transaction Agreement is a valid and binding obligation of Purchaser and Parent
  enforceable against Purchaser and Parent in accordance with its terms. 

                10.
              The
  execution and delivery by Purchaser and Parent of the Transaction Agreements
  do not, and the performance by Purchaser and Parent of their respective obligations
  thereunder will not: (a) violate any law of the State of Arizona or the United
  States of America or any rule or regulation issued thereunder; (b) violate any
  judgment, injunction, order or decree; (c) violate any provision of the charter
  or bylaws of either Purchaser or Parent; or (d) breach or result in a default
  under any agreement or instrument listed on Schedule ___ hereto. 

                11.
             The execution
  and delivery by Purchaser and Parent of the Transaction Agreements do not, and
  the performance by Purchaser and Parent of their respective obligations thereunder
  will not, require approval from or any filings with any governmental authority
  under any law of the United States of America or the State of Arizona, or any
  rule or regulation thereunder. 

                12.
              Upon filing
  in the office of the Arizona Secretary of State and the payment of all required
  filing fees, any UCC financing statement filed in connection with Seller’s
  perfection of the security interest in the Collateral (as defined in the Pledge,
  Security Agreement and Collateral Assignment between Purchaser, Seller and the
  Company, dated __________ , ___, ____), will perfect Seller’s security
  interest in the Collateral. No other filings, registrations or recordations
  are necessary under the Uniform Commercial Code as in effect in the State of
  Arizona to perfect such security interest in the Collateral. 

                13.
             To our knowledge,
  neither Purchaser nor Parent is a party to any pending action or proceeding,
  and no action or proceeding has been overtly threatened in writing, that may
  adversely affect the transactions contemplated by the Transaction Agreements
  or that may have a material adverse effect on either Purchaser or Parent.
