2.4. Consents.

(a) Efforts and Cooperation.

For purposes of the Assigned Leases, a PDHC Consent shall only be necessary to the extent a consent or approval is required under the terms and conditions of each respective lease or sublease, and ADPI Parties shall not delay or withhold obtaining or accepting any PDHC Consent where the party from whom such consent or approval is being sought is willing to grant such consent or approval but is not willing to grant any ADPI Party a release or other term beyond the consent or approval required under the particular lease or sublease.

(b) Alternatives Where Consent Not Obtained by Closing. Notwithstanding any other provision of this Agreement to the contrary, PDHC’s obligation to assign or transfer any PDG Assigned Asset for which a PDHC Consent is required shall be contingent upon PDHC obtaining such PDHC Consent; provided that with respect to any Assigned Lease for which PDHC Consent is required and is not obtained by the Closing Date:

(i) At the Closing, PDHC and the applicable PDG Party(ies) shall enter into a non-contingent assignment and assumption agreement or such other agreements as may be reasonably necessary for the applicable PDG Party(ies) to have the benefits, and assume the financial and other obligations, of PDHC as tenant and/or subtenant, as applicable, under such Assigned Lease, which agreements shall contain a provision under which:

(A) PDG, and Dental Specialists as applicable, provide PDHC and ADPI, to the extent ADPI is a guarantor under the applicable Assigned Lease, with indemnification against all obligations and liabilities of the tenant under such Assigned Lease arising after the Closing Date, and against all liabilities, damages, claims, losses, costs, and expenses, including without limitation attorneys’ fees, arising out of any failure by PDG, and/or Dental Specialists as applicable, to perform and observe all obligations to be performed or observed by PDG, and/or Dental Specialists as applicable, under such Assigned Lease, but excluding liabilities, damages, claims, losses, costs, and expenses arising out of PDHC’s failure to obtain any PDHC Consent from the applicable landlord; and

(B) For a period not to exceed ten (10) years from the Closing Date, PDHC provides the applicable PDG Party(ies) with indemnification (i) against all obligations and liabilities of the tenant under such Assigned Lease arising on or before the Closing Date (other than resulting from failure to obtain a PDHC Consent) and (ii) against harm proximately resulting from failure to obtain a PDHC Consent to the extent such PDG Party(ies) are actually harmed by the failure of PDHC to obtain such consent, and against the cost and expenses incurred by such PDG Party(ies) proximately resulting from PDHC’s failure to obtain any PDHC Consent, including, but not limited to any rent or accelerated gross rent at the existing location, and if the applicable PDG Party is evicted from the space, reasonable moving and relocation expenses, lost leasehold improvements, reasonable costs of installing relocated leasehold improvements or new leasehold improvements of similar quality in a new clinic location, the gross rent differential between the gross rent payable under the applicable Assigned Lease and the gross rent (not to exceed then current market rates for space of similar size, quality, and location as the space identified in the applicable Assigned Lease) payable under the new space lease, and up to three (3) months’ lost profits from the lost location. PDG, and/or Dental Specialists as applicable, shall use commercially reasonable efforts to mitigate its damages resulting from PDHC’s failure to obtain a PDHC Consent. Notwithstanding the foregoing, PDHC shall have no indemnification or other obligation to PDG Parties related to the failure to obtain a PDHC Consent for the assignment of the applicable Assigned Lease if the PDHC Consent is withheld because (i) of PDG’s failure to reasonably cooperate in PDHC’s efforts to obtain such consent, or (ii) the landlord rejects PDG as a viable tenant;

(ii) Provided that (A) PDG Parties have not defaulted hereunder or under the applicable Assigned Lease, (B) the applicable PDG Party(ies) have notified PDHC in writing of their desire to extend the term of such Assigned Lease at least ten (10) business days

prior to the date notice of an extension is required from the tenant/subtenant, as applicable, under such Assigned Lease, and (C) the exercise of any particular extension option available under the Assigned Lease will not extend the term of such Assigned Lease beyond the tenth (10th) anniversary of the Closing Date, then PDHC shall be obligated to timely exercise, or consent to such PDG Party’s(ies’) exercise of, any right of renewal or extension of the term of such Assigned Lease;

(iii) PDHC, ADPI and PDG Parties shall continue after the Closing their efforts as provided in the first sentence of Section 2.4(a) to obtain the required PDHC Consent and complete the assignment of such Assigned Lease to PDG; and

(iv) If, after the Closing Date, a PDG Party defaults as to any obligations under or with respect to an Assigned Lease and does not cure such default within any applicable cure period, of which PDHC is the named tenant, obligor or guarantor, PDHC shall have the right, after five (5) business days prior written notice to such PDG Party, to cure such PDG Party’s default under the applicable Assigned Lease. To the extent PDHC cures a PDG Party’s default under an Assigned Lease, PDHC shall be entitled to reimbursement from such PDG Party for all reasonable costs and expenses incurred by PDHC proximately resulting from such default and cure, or take any action at law or equity to take occupancy of the premises under the Assigned Lease that such PDG Party has defaulted upon.

(c) Renewals and Extensions. PDHC hereby consents to each and every exercise of any tenant renewal or extension option which a PDG Party may from time to time exercise under each Assigned Lease, provided that such extension will not extend the term of such Assigned Lease beyond the tenth (10th) anniversary of the Closing Date. If PDHC fails to execute and deliver a separate consent (or expressly and in detail explain in writing its objection) to a PDG Party’s exercise of an applicable extension or renewal option, the applicable PDG Party(ies) and the other party(ies) to the applicable Assigned Lease shall have the right to rely upon the foregoing sentence as conclusive evidence of PDHC’s consent to the PDG Party’s(ies’) exercise of such option. PDG Parties shall use commercially reasonable efforts in attempting to obtain a release of PDHC in connection with PDG Party’s(ies’) exercise of any existing extension options contained within an Assigned Lease.

(d) Costs of Separation. Except as otherwise provided in Section 2.5, all costs and expenses related to the assignment (excluding legal fees and expenses of ADPI Parties), transfer, or conveyance of the Assigned Leases, all related consents or approvals, and all related transfer taxes or other similar taxes, assessments, or charges, including without limitation build-out costs to separate the existing spaces into two completely separate and distinct spaces (unless the Parties agree that completely separate and distinct spaces is not required for any particular location) shall be paid by PDG Parties.

2.5. Additional Site Specific Transfer Requirements. In addition to the procedures and concepts set forth in Article II herein above for transferring the Assigned Leases, three (3) of the Assigned Leases will require some additional documents and steps to complete such transfer. Those special sites and additional requirements are as follows:

(a) Park Dental High Pointe (General), Lake Elmo, MN (#20 in Schedule 2.1(a)).

(i) Separation of Space. This site currently contains three (3) practice groups (Park Dental General Dentistry; Apple Park/Orthodontic Care Specialists (“OCS”); and East Group) within the leased premises. ADPI Parties and PDG Parties anticipate (with the landlord’s cooperation) dividing this space into two (2) completely separate and distinct leased areas with their own independent lease based upon the existing lease. This plan requires the following documents and issues to be addressed in order to transfer this Assigned Lease: (i) PDHC or its designee and landlord will enter into a new lease for the space currently occupied by OCS; (ii) PDG or Dental Specialists and landlord will enter into a new lease for the remainder of the space covered by the existing lease; (iii) PDHC and landlord shall execute a termination of the existing Lease; (iv) subject to landlord approval, PDHC will retain the existing “Orthodontic Care Specialists, Ltd” building signage which is located over the OCS space, PDG will retain the existing “Park Dental High Pointe” building signage which is located over the PDG space, and the current monument sign must be replaced with one or two separate sign cover(s), as necessary, showing PDG’s name on top and OCS’s name underneath PDG’s name; and (v) this separation of space will require certain tenant improvements to be installed/modified including but not limited to lockable doors and walls to separate the spaces, one or both new spaces will need to be re-keyed, separate metering/submetering, and separate controls, of water, sewer, gas and electric services to each leased premises (to the extent such metering and/or controlling is feasible in a cost effective manner considering the length of the remainder of the term of the Assigned Lease and possible extensions thereof), and separate trash receptacles will need to be provided. The Parties acknowledge that the mechanical room, front vestibule and part of the existing staff hallway shall be common areas and pro rated accordingly. Each of the ADPI Parties and PDG Parties will use reasonable, commercial efforts to accomplish the foregoing separation of the space on or before May 30, 2008. Notwithstanding Section 2.4 above, PDG and PDHC shall share the total cost of such separation on a pro rata basis based upon the rented square footage under the separate leases, but each party shall be responsible for their respective signage at the site.

Pointe Shared Item and how such shared item(s) shall be operated, maintained and replaced by the Parties during the term of the Assigned Lease and extensions thereof, including without limitation turning on and off such items; controlling such items during and after business hours, safe/efficient/non-wasteful operation of such items, and the concepts/issues identified in Section 2.5(e)(2) and (3) below. Until such time as the further separation is completed and/or the shared operation agreement is executed, any costs associated with maintaining, cleaning, replacing or repairing the High Pointe Shared Item, including without limitation, repair costs or monthly fees, to be paid by the tenants under the separate leases, shall be allocated pro rata to the Parties based on rented square footage.

(iii) Mold Remediation. In addition, each Party shall be responsible for any existing mold that needs to be remediated, if any, within their respective space. PDG shall be responsible for completing any mold remediation within the shared areas, but the cost of such remediation shall be shared between the Parties based upon the rented square footage under the separate leases.

(iv) Cooperation. The Parties agree to reasonably cooperate with each other in providing the landlord with any documentation or information necessary to facilitate the separation of the two (2) spaces.

(b) Ridges Burnsville Dental Building, Burnsville, MN (#21 & 22 in Schedule 2.1(a)).

(i) Separation of Space. This site currently contains three (3) practice groups (PDHC General Dentistry; PDG Specialty/Pediatric Specialty; and South Group) within the leased premises. ADPI Parties and PDG Parties anticipate (with the landlord’s cooperation) dividing this space into two (2) completely separate and distinct leased areas with their own independent lease. This plan requires the following documents and issues to be addressed in order to transfer this Assigned Lease: (i) PDHC or its designee and landlord will enter into a new lease for the space currently occupied by PDHC General Dentistry and the South Group small conference room (Conference Room #1); (ii) PDHC and landlord will execute an amendment to the existing lease removing the space currently occupied by PDHC General Dentistry and the South Group small conference room (Conference Room #1) from the existing lease (iii) PDHC will assign all of PDHC’s interests under the existing lease to PDG and Dental Specialists, and PDG and Dental Specialists shall assume such interests and obligations after such assignment; (iv) subject to landlord approval, PDHC will retain the “Park Dental Ridges” building sign square footage and sign locations, except for the “Park Dental Ridges” sign located above the mechanical room, which is deemed over the PDG space, which sign shall be transferred to PDG (under no circumstances shall PDHC use the actual “Park Dental Ridges” signage), PDG will retain the “The Dental Specialists” building signage which is located over the PDG space, PDHC shall retain the “Park Dental Ridges” monument signage square footage (but shall not use the actual sign face), and PDG shall retain the “The Dental Specialists” monument signage and square footage, but PDHC’s monument signage that is located at the entrance of the parking lot shall be relocated to the bottom of such monument sign, PDHC shall have the top position of the other identifying monument sign located at the corner of Nicollet Boulevard and Nicollet Avenue; and (v) this separation of space will require certain tenant improvements to be installed/modified including but not limited to lockable doors and walls to separate the spaces,

(including a demising wall within the back hallway to replace the existing doorway and reconfiguring Conference Room #1 as shown in Schedule 2.5(b)(i) attached hereto and relocating certain “Exit” signs and/or fire sprinkler heads and lines in order to fully comply with applicable city and building codes, provided that no such work or demolition shall be performed until building permits are issued) one or both new spaces will need to be re-keyed, separate metering/submetering, and separate controls, of water, sewer, gas and electric services to each leased premises (to the extent such metering and/or controlling is feasible in a cost effective manner considering the length of the remainder of the term of the Assigned Lease and possible extensions thereof), the existing security system and intercom system needs to be separated or an additional system installed, an additional/separate telephone system will need to be installed in the PDHC Space, and separate trash receptacles will need to be provided. The Parties acknowledge that the mechanical room, medical gas closets, and a portion of the back hallway to access the mechanical room shall be common areas and pro rated accordingly. Additionally, pursuant to the Transition Services Agreement, PDHC is required to provide certain “continuing care services” (as defined in the Transition Services Agreement) to PDG at this site (the “Ridges Continuing Care Services”) until the Doctor Transition Date. The Parties agree that the PDHC personnel that conduct the Ridges Continuing Care Services will be located within the PDG Space. Each of the ADPI Parties and PDG Parties will use reasonable, commercial efforts to accomplish the foregoing separation of the space on or before May 30, 2008. Notwithstanding Section 2.4 above, PDG and PDHC shall share the total cost of such separation on a pro rata basis based upon the rented square footage under the separate leases, but each party shall be responsible for their respective signage at the site.

(ii) Mechanical Systems/Space. The Parties acknowledge that it is not economically practical to split the building’s mechanical systems into two separate spaces, or to separate the shared dental equipment prior to the Closing Date and it may or may not be cost effective to do so after the Closing Date. Therefore, with the landlord’s approval and agreement to manage the shared space, the existing mechanical room, medical gas closets, mop sink and HVAC unit, as well as the existing shared dental equipment (i.e. compressors and medical gas systems), shall be used and shared (collectively, the “Ridges Shared Item”) by both Parties until such time as PDG, with PDHC’s reasonable cooperation, determines whether it is cost effective to further separate (i.e. separate metering or submetering and providing separate controls for) some or all of the Ridges Shared Items. If PDG, with PDHC’s reasonable cooperation, determines in good faith that: (A) it is feasible to further separate some or all of such items in a cost effective manner, then PDG, with PDHC’s reasonable cooperation, shall use commercially reasonable efforts to complete such further separation—subject to landlord approval to the extent required under the Assigned Lease—no later than May 30, 2008; and/or (B) it is not feasible to further separate one or more of such items, then no later than May 30, 2008, the Parties shall have negotiated (in good faith) and executed a shared operation agreement which provides in detail the terms and conditions of the Parties shared use of the remaining Ridges Shared Item and how such shared item(s) shall be operated, maintained and replaced by the Parties during the term of the Assigned Lease and extensions thereof, including without limitation turning on and off such items; controlling such items during and after business hours, safe/efficient/non-wasteful operation of such items, and the concepts/issues identified in Section 2.5(e)(2) and (3) below. Until such time as the further separation is completed and/or the shared operation agreement is executed, any costs associated with maintaining, cleaning, replacing or repairing a Ridges Shared Item, including without limitation, any property management fees, repair costs or monthly fees, to be paid by the tenants under the separate leases, shall be allocated pro rata to the Parties based on rented square footage.

(iii) Cooperation. The Parties agree to reasonably cooperate with each other in providing the landlord with any documentation or information necessary to facilitate the separation of the two (2) spaces.

(i) Separation of Space. This site currently contains two (2) practice groups (PDG General Dentistry and OCS) within the leased premises. ADPI Parties and PDG Parties anticipate (with the landlord’s cooperation) dividing this space into two (2) completely separate and distinct leased areas with their own independent lease. This plan requires the following documents and issues to be addressed in order to transfer this Assigned Lease: (i) PDHC and landlord will enter into a new lease for the space currently occupied by OCS; (ii) PDHC and landlord will execute an amendment to the existing lease removing the space currently occupied by OCS from the existing lease; (iii) PDHC will assign all of PDHC’s interests under the existing lease to PDG and PDG shall assume such interests and obligations arising after such assignment; (iv) PDHC and PDG Parties agree that the existing building signage shall be divided between the parties on the basis of the rented square footage of the separate leases and each Parties’ respective building sign(s) shall only be located over their respective space within the building, provided, however, that PDG shall remove and resize one or both of the existing “Brookpark Dental Center” signs as necessary, to permit PDHC to place the “Orthodontic Care Specialists, Ltd.” identifying sign on the building (which sign shall not exceed PDHC’s pro rata share of the existing building sign square footage) which sign shall be in compliance with the landlord’s and/or any city or municipal requirements, and with respect to the monument signage PDG shall retain the “Brookpark Dental Center” signage and location and PDHC will retain the “Orthodontic Care Specialists, Ltd.” signage and location; and (v) this separation of space will require certain tenant improvements to be installed/modified including but not limited to lockable doors and walls to separate the spaces, one or both new spaces will need to be re-keyed, separate metering/submetering, and separate controls, of water, sewer, gas and electric services to each leased premises (to the extent such metering and/or controlling is feasible in a cost effective manner considering the length of the remainder of the term of the Assigned Lease and possible extensions thereof), re-keying the existing staff bathrooms so that one can be used by PDHC’s patients and one can be used by PDHC and PDG staff, and separate trash receptacles will need to be provided. The Parties acknowledge that the mechanical room, the patient and staff bathrooms, and part of the existing staff and bathroom hallway shall be common areas and pro rated accordingly. Each of the ADPI Parties and PDG Parties will use reasonable, commercial efforts to accomplish the foregoing separation of the space on or before May 30, 2008. Notwithstanding Section 2.4 above, PDG and PDHC shall share the total cost of such separation on a pro rata basis based upon the rented square footage under the separate leases, but each party shall be responsible for their respective signage at the site.

and HVAC unit, as well as the existing shared dental equipment (i.e. compressors), shall be used and shared (collectively, the “Brookpark Shared Item”) by both Parties until such time as PDG, with PDHC’s reasonable cooperation, determines whether it is cost effective to further separate (i.e. separate metering or submetering and providing separate controls for) some or all of the Brookpark Shared Items. If PDG, with PDHC’s reasonable cooperation, determines in good faith that: (A) it is feasible to further separate some or all of such items in a cost effective manner, then PDG, with PDHC’s reasonable cooperation, shall use commercially reasonable efforts to complete such further separation—subject to landlord approval to the extent required under the Assigned Lease—no later than May 30, 2008; and/or (B) it is not feasible to further separate one or more of such items, then no later than May 30, 2008, the Parties shall have negotiated (in good faith) and executed a shared operation agreement which provides in detail the terms and conditions of the Parties shared use of the remaining Brookpark Shared Item and how such shared item(s) shall be operated, maintained and replaced by the Parties during the term of the Assigned Lease and extensions thereof, including without limitation turning on and off such items; controlling such items during and after business hours, safe/efficient/non-wasteful operation of such items, and the concepts/issues identified in Section 2.5(e)(2) and (3) below. Until such time as the further separation is completed and/or the shared operation agreement is executed, any costs associated with maintaining, cleaning, replacing or repairing a Brookpark Shared Item, including without limitation, repair costs or monthly fees, to be paid by the tenants under the separate leases, shall be allocated pro rata to the Parties based on rented square footage.

(iii) Cooperation. The Parties agree to reasonably cooperate with each other in providing the landlord any documentation or information necessary to facilitate the separation of the two (2) spaces.

(d) If Any Landlord Refuses to Give Consent to Separation of Spaces. If any landlord at the Park Dental High Pointe, Ridges or Brookpark sites should refuse to grant its consent to the proposed separation of the applicable space, then with respect to such site the Parties shall: (i) cause the applicable Assigned Lease to be fully assigned (i.e. covering all of the leased space without separation) to PDG, since PDG is the larger of the two tenants at these spaces; and (ii) the Parties shall enter into a sublease of the smaller space on terms and conditions that equate to a pass through of all liability and obligations of tenant under such Assigned Lease to the applicable subtenant for the remainder of the term under the Assigned Lease, less one day, and such sublease shall include any options to extend or renew that may be included in the Assigned Lease.

(e) Post Closing Events That May Affect Shared Items. In addition:

(1) If the sharing relationship between the Parties, relative to any one or more of the Park Dental High Pointe, Ridges or Brookpark sites is unworkable in the reasonable opinion of either Party, then either Party shall have the right to resort to the dispute resolution provisions under Section 8.5 of this Agreement for redress.

(2) If either Party desires to vacate, sublet or assign its rights under, or terminate prior to the expiration of the term of, its lease for such Party’s separated space at the Park Dental High Pointe, Ridges or Brookpark sites, then such party shall, subject to landlord

approval (to the extent required under the applicable lease), offer such space to the other Party, and the Parties shall negotiate in good faith for a period of thirty (30) days to come to terms reasonably acceptable to both Parties, to consummate the proposed transfer of space and/or rights to the other Party as a way of terminating the shared relationship with respect to the applicable Shared Items. If the other Party elects not to so obtain the applicable rights and/or space, the Party desiring to vacate, sublet, assign or terminate shall be free to pursue such opportunities with third parties.

(3) At any point in time during which a shared relationship continues, if either Party desires to terminate the shared relationship with respect to the shared dental equipment, such Party (the “Terminating Party”) shall have the right to terminate that relationship by installing its own separate dental equipment within its own space or the shared mechanical room (to the extent space is then available therein), at its own expense. Upon completion of such installation, the shared relationship (with respect to only the then-separated dental equipment) shall terminate; provided, however the voluntary separation contemplated by this provision shall not result in the loss of access or use of the shared equipment by the non-Terminating Party, unless agreed to by the non-Terminating Party, and further provided that the non-Terminating Party shall thereafter be solely responsible for the repair and replacement of the formerly shared dental equipment. Moreover, following such termination the Terminating Party shall no longer be required to pay any portion of the rent or additional rent in connection with the shared space in which the formerly shared dental equipment was located, unless the Terminating Party is otherwise using such shared space following the termination.

EMPLOYMENT AND RESTRICTIONS; INTERIM OPERATIONS; PRE-CLOSING COVENANTS

5.1 Employment of Doctors. With respect to each Non-PDG Doctor, each PDG Party hereby represents, warrants, covenants and agrees that concurrent with the Closing, but effective December 31, 2007 each Non-PDG Doctor has been released from any and all (a) geographic non-competition covenants or restrictions set forth in any employment or other agreement between that Non-PDG Doctor and PDG Parties, and (b) the non-solicitation or

similar provisions in any such agreement to the extent they relate to the Northland Patient (collectively, the “Restrictive Covenants”). Further, without limiting the preceding sentence, each PDG Party hereby waives and releases any right, claim, or cause of action arising from or related to any claimed breach of any Restrictive Covenant to the extent released under the preceding sentence.

5.2 Prohibition on Solicitation of Doctors.

(a) Solicitation of PDG Doctors. Each ADPI Party hereby represents, warrants, covenants and agrees that, during the period commencing January 1, 2008 and ending on September 30, 2009, both dates inclusive (the “Recruitment Restriction Period”), no ADPI Party and no affiliate of ADPI Parties has, and no ADPI Party or any affiliate thereof shall, solicit or recruit, or attempt to solicit or recruit, for employment by any ADPI Party or any affiliate thereof (for purposes of this section, “affiliate” shall include, without limitation, any subsidiaries and affiliated dental groups), any PDG Doctor.

(b) Solicitation of Non-PDG Doctors. Each PDG Party hereby represents, warrants, covenants and agrees that, during the Recruitment Restriction Period, no PDG Party and no affiliate of PDG Parties has, and no PDG Party or any affiliate thereof shall, solicit or recruit, or attempt to solicit or recruit, for employment by any PDG Party or any affiliate thereof (for purposes of this section, “affiliate” shall include, without limitation, any subsidiaries and affiliated dental groups), any Non-PDG Doctor.

(c) Remedy. Each Party hereby acknowledges and agrees that: (i) the provisions of this Section 5.2 are fundamental for the protection of each Dental Practice’s legitimate business interests; (ii) such provisions are reasonable and appropriate in all respects; and (iii) in the event a Party or any of its affiliates violates any such provisions, the Dental Practice(s) for whose benefit such provision is intended (PDG Parties, in the case of Section 5.2(a), and Northland, in the case of 5.2(b)) would suffer irreparable harm and its remedies at law are inadequate. Accordingly, in the event any Party or its affiliates violates such provisions, then notwithstanding the dispute resolutions provisions set forth in Section 8.5, the Dental Practice(s) for whose benefit such provision is intended shall be entitled to a temporary restraining order, temporary and permanent injunctions, specific performance, and other equitable relief without any showing of irreparable harm or damage, or the posting of any bond, in addition to any other rights or remedies which may then be available to the Dental Practice at law or in equity.

5.3 Employment of Team Members. As used in this Agreement the term “Team Member” shall mean any individual other than a licensed dentist who is or was employed by PDG Parties or ADPI Parties. Any Party to this Agreement may solicit, recruit, or hire any Team Member employed by any other Party, or any of such Party’s affiliates, and such Team Member shall have the right to accept employment with any Party, or any of such Party’s affiliates, unrestricted by any non-competition agreement or similar restriction otherwise enforceable by the Party previously employing that Team Member.

5.4 Doctor Relocation and Access. On or before the Doctor Transition Date, ADPI Parties shall cause each Non-PDG Doctor practicing in a PDG Office to be relocated to an

office other than a PDG Office, and PDG Parties shall cause each PDG Doctor practicing in a PDHC Office to be relocated to an office other than a PDHC Office. Until the earlier of such relocation or the Doctor Transition Date with respect to a Doctor, each PDG Doctor who was practicing in a PDHC Office as of January 2, 2008, shall continue to have the right to practice and work in that PDHC Office. Each such PDG Doctor, while still practicing in the applicable PDHC Office prior to the Doctor Transition Date, shall have the right to continue practicing under circumstances generally consistent with the circumstances of that Doctor’s practice in that Office generally in effect in 2007, including without limitation days and hours of practice, number of operatories utilized, and number and type of support personnel, as generally applicable and ADPI Parties shall exercise reasonable efforts to schedule PDG Doctors who were practicing in a PDHC Office as of January 2, 2008 in such PDHC Office prior to the Doctor Transition Date. The foregoing right shall also apply to any other licensed dentist temporarily filling-in for a Doctor because that Doctor is temporarily physically unable to perform his or her regular duties as a Doctor. In addition, PDHC shall not discriminate against its employees who work with PDG Doctors in a PDHC Office on the basis that such employees are or may be leaving with such PDG Doctors.

5.5 Patients and Patient Records.

The following procedures shall apply from the date of this Agreement until the expiration of the Doctor Transition Period:

(a) Patient Elections. Notwithstanding any other provisions of this Agreement to the contrary, and provided that, (i) an ADPI Party did not act in a manner in violation of the terms of this Agreement or (ii) a Non-PDG Doctor did not act in a manner in violation of any non-competition or non-solicitation provision not otherwise released or waived under this Agreement, to cause a Patient to choose another doctor, if a Patient elects or requests to be treated by a particular doctor even if not that Patient’s Doctor of Record or if inconsistent with the assignment of that Patient pursuant to the provisions of this Agreement, then that Patient will be assigned as so requested or elected.

(b) Doctor of Record. The Parties agree that determining a Patient’s doctor of record (“Doctor of Record”) may be problematic under certain scenarios. Therefore, for the avoidance of doubt, the Parties hereby agree that the method for determining a Patient’s Doctor of Record shall be as follows:

(i) The Doctor of Record for any Current Patient, shall be the Doctor (if any) who was the Doctor seen in a majority of the last three (3) dental care visits to any Office prior to January 1, 2008, as indicated on the lists which shall be generated from PDHC’s practice management system no later than March 17, 2008 in accordance with the requirements described in Section 5.5(b)(v) below (“Initial List”).

(ii) If a Doctor of Record cannot be determined applying the method set forth in Section 5(b)(i) because two (2) of the last three (3) doctors a Current Patient has seen during such Current Patient’s immediately preceding three (3) Office visits prior to January 1, 2008 are no longer a PDG Doctor or Non-PDG Doctor, the Doctor of Record shall be the last PDG Doctor or Non-PDG Doctor seen by such Current Patient.

(iii) If a Doctor of Record cannot be determined applying the methods set forth in Section 5(b)(i) or (ii) because a Current Patient has seen three (3) different doctors during such Current Patient’s immediately preceding three (3) Office visits, then the Doctor of Record for such Patient shall be determined as follows:

(A) PDHC shall, no later than March 17, 2008, create a list of all Current Patients who have seen three (3) different doctors during such Current Patient’s immediately preceding three (3) Office visits, as indicated on the Initial List (the “Unassigned Patients”);

(B) The list of Unassigned Patients shall be alphabetized by the Patient’s last name and numbered sequentially, and every odd-numbered Unassigned Patient shall be placed on one list (the “Majority Allocation List”), and every even-numbered Unassigned Patient shall be placed on another list (the “Last Doctor Seen List”);

(C) As to Current Patients on the Majority Allocation List where Non-PDG Doctors comprise a majority of the three (3) doctors who last saw such Current Patient prior to January 1, 2008, such Current Patients shall have such Non-PDG Doctors as their Doctors of Record. As to all other Current Patients on the Majority Allocation List, such Current Patients shall have a PDG Doctor as their Doctor of Record; and

(D) The Doctor of Record for Current Patients on the Last Doctor Seen List shall be the Doctor who last saw such Current Patient in an Office prior to January 1, 2008.

(iv) Notwithstanding the foregoing, the Parties agree that if the means of determining the Doctor of Record set forth in Section 5(b)(i), (ii) or (iii) above result in an injustice as to any particular Patient (e.g. a Patient being assigned to a Doctor which the Patient does not consider to be his or her Doctor) and the Parties are unable to reach agreement as to appropriate assignment, the Party seeking the re-assignment of the applicable Patient must making a fact-specific showing of the unfairness of the assignment to the Special Master and upon such showing the identification of the Doctor of Record shall be adjusted accordingly. The lists generated pursuant to Section 5(b)(i), (ii) or (iii) shall be open for review by the PDG Doctors and Non-PDG Doctors to assist in the determination of whether the lists result in an unjust assignment of any particular Patient.

(v) The Initial List shall be created and delivered to PDG Parties in an Excel spreadsheet in a format reasonably acceptable to both PDHC and PDG, with any dispute regarding format being resolved by the Special Master pursuant to Section 8.5.

(c) Assignment of Patients Between Dental Practices. As among the Parties, subject to Section 5.5(a), the Patients shall be assigned as follows:

(i) PDG Patients shall remain with PDG.

(ii) Northland Patients shall be assigned to Northland.

(iii) New Patients shall be assigned by Office. All New Patients seen at a PDG Office shall be assigned to PDG, and PDG shall have the right to assign them to individual doctors employed or otherwise retained (hereinafter simply “employed”) by PDG. All New Patients seen at a Non-PDG Office shall be assigned to Northland, and Northland shall have the right to assign them to individual doctors employed by Northland.

(d) Solicitation of Patients. Without limiting the other provisions of this Article V or the rights of Non-PDG Doctors to otherwise solicit patients (subject to any contractual restrictions that remain in effect), each Non-PDG Doctor shall have the right to send a letter substantially in the form attached hereto as Exhibit M to the Northland Patients for whom that Non-PDG Doctor is the Doctor of Record, and ADPI Parties shall have access to the Northland Patient addresses and other contact information for purposes of solicitation. However, these are not the exclusive methods by which the Non-PDG Doctors may solicit the Northland Patients, or seek a transfer of the record of any Patient, so long as that solicitation is not inconsistent with this Agreement.

(e) Patient Records. Subject to the provisions of this Section 5.5, PDG Parties own and retain exclusive control of Current Patient records. Until December 31, 2008, PDHC shall be the custodian of Current Patient records owned by PDG and located at PDHC Offices. PDHC and PDG Parties shall enter into a HIPAA business associate agreement, attached hereto as Exhibit N, relating to PDHC’s role as records custodian and the access to such records by the Non-PDG Doctors and Northland. PDHC is authorized to transfer , on behalf of PDG, Current Patient records to Northland upon the direction of a Current Patient. PDHC may either transfer a copy of the Current Patient records or transfer the original records and provide PDG with a copy. In either instance, PDHC or Northland shall be responsible for the cost of copying the records. Neither PDHC nor PDG Parties will create unnecessary obstacles to Non-PDG Doctors to solicit Northland Patients and obtain the transfer of patient records to Northland, regardless of the location of the records.

(f) Compliance With Law. The Parties shall exercise reasonable efforts to comply with applicable federal and state law regarding handling of Patient records.

(g) Patient Scheduling. ADPI Parties agree that if a Patient calls a PDHC Office to schedule an appointment with a PDG Doctor, and that PDG Doctor has changed Offices, that Patient shall be given the new contact information for his or her PDG Doctor. PDG Parties agree that if a Patient calls a PDG Office to schedule an appointment with a Non-PDG Doctor, and that Non-PDG Doctor has changed Offices, that Patient shall be given the new contact information for his or her Non-PDG Doctor. These procedures shall remain in place until December 31, 2008.

5.6 Allocation of Revenue and Expense. As a general principle, the cash generated from and after January 1, 2008 forward for dental care performed by a Doctor, or by any hygienist working with or under the supervision of that Doctor, shall be allocated to the Dental Practice which employed that Doctor at the time such dental care was performed, and such cash shall be transferred by PDG to Northland, or by Northland/PDHC to PDG, as necessary to reflect that allocation promptly following such Party’s receipt of such cash and reasonable verification of the allocation thereof. To the extent necessary to effectuate such allocation or comply with applicable law or third party payor agreements, each Dental Practice shall be deemed to be acting as a sub-contractor of the other Dental Practice for that limited purpose, but only through January 11, 2008.

Until the Doctor Transition Date, Clinic Expense (as defined in the Transition Services Agreement) shall be allocated and paid as provided in the Transition Services Agreement.

5.7 Office Sharing. Notwithstanding Section 5.6, until the Doctor Transition Date, with respect to any Office in which at least one PDG Doctor and at least one Non-PDG Doctor are practicing, the following provisions shall apply after January 11, 2008:

(a) Dual Systems. For each such Office, PDHC shall maintain dual systems to record financial activity and other matters resulting from treatment and other interactions with Patients examined or treated by Doctors employed by PDG, on the one hand, and Patients examined or treated by Doctors employed by Northland, on the other hand. The services provided by Doctors employed by Northland shall be billed under Northland’s taxpayer identification number, and under Northland’s new arrangements with third party insurance providers, and not under PDG’s taxpayer identification number or insurance contracts. The services provided by Doctors employed by a PDG Party shall be billed under such PDG Party’s taxpayer identification number, and under such PDG Party’s arrangements with third party insurance providers. PDHC shall, upon request, allow PDG Parties reasonable access during normal business hours to all books and records pertaining to such financial activity and other matters resulting from treatment and other interactions with Patients to ensure compliance with this section.

(b) Practice Identification. Not later than March 7, 2008, PDHC shall post at each such Office signs, nameplates or similar items identifying the trade names of the two Dental Practices practicing at that Office and the name of the individual Doctors practicing there on behalf of each Dental Practice, and ADPI Parties shall cease using the Park Dental Name after a reasonable transition period (not to exceed ninety (90) days) after the Closing Date (not to exceed ninety (90) days), provided that (i) the Parties acknowledge that (A) certain uses (for example, and without limitation, telephone directory listings) may not be subject to change for an extended period of time, and (B) certain changes are subject to availability of third-party consents, contractors or other resources, and (ii) ADPI Parties shall not be required to sacrifice the quality or appearance of signage or other uses of the Park Dental Names in order to expedite the change necessary to terminate their use of such names. ADPI Parties represent and warrant that since the Settlement Date they have not placed or renewed, except as disclosed in Schedule 5.7(b), and ADPI Parties covenant that after the Closing Date they will not place or renew, without exception, any listing in any “White Pages” or any “Yellow Pages” telephone

directory for the Twin Cities, Minnesota metropolitan area in which any PDHC Office is listed in a manner that either uses any Park Dental Name or any of the Telephone Numbers to identify that PDHC Office.

(c) Patient Notification. Each Patient shall be informed, in the Office and in telephone communications, of the Dental Practice by which the Doctor with whom such Patient is schedule is employed.

5.8 Insurance. For so long as the doctors employed by Northland are practicing in PDG Offices, Northland shall arrange to have PDG named as an additional insured under Northland’s general and professional liability insurance policies. Similarly, for so long as any doctor employed by PDG is practicing in a PDHC office, PDG shall arrange to have ADPI Parties named as additional insureds on PDG’s general and professional liability policies. All such insurance policies shall provide for at least 30 days advance written notice to the covered Party from the insurer with respect to any alteration of coverage, cancellation, or proposed cancellation for any reason. Each Party required to provide insurance coverage to another Party pursuant to the preceding provisions of this Section 5.8 shall promptly provide a certificate evidencing such coverage to the Other Party.

5.9 Termination of Service Agreement. PDG Parties and ADPI Parties hereby acknowledge and agree that: (a) the Service Agreement has been terminated effective December 31, 2007 and as of the Closing Date the ADPI Parties have no claim for accounts receivable due from PDG as of December 31, 2007 arising pursuant to the Service Agreement; (b) neither PDG Party shall be prohibited from providing any type of management or administrative services or products to the other PDG Party; and (c) pursuant to the Settlement Agreement, the daily transfers from the Provider Account (as defined in the Service Agreement) were terminated on January 14, 2008, and PDG Parties now have control over the Provider Account and all of their funds.

5.10 No Movement of Assets. ADPI Parties, jointly and severally, represent and warrant that, other than consumable items used or inventory items transferred amongst the Offices in the ordinary course of business, they have not, nor has any other affiliate of any ADPI Party, moved or transferred or caused to be moved or transferred any material tangible asset of the type included in the PDG Assigned Assets and typically located in a PDG Office prior to the Settlement Date to another office or location, and ADPI Parties further covenant and agree that from and after the date of this Agreement they shall not, nor shall any affiliate of any ADPI Party, move or transfer or cause to be moved or transferred material tangible asset of the type included in the PDG Assigned Assets and typically located in the PDG Offices to another office or location without the prior written consent of PDG.

All such Material Contracts are valid and binding, in full force and effect, and enforceable in accordance with their respective terms. To their knowledge, neither PDHC or ADPI is in violation of or in default in respect of, nor has there occurred an event or condition which, with the passage of time or giving of notice (or both) would constitute a material default by either or both of them of, any such Material Contract. Except as set forth in Schedule 6.1(i), PDHC has provided PDG with true and complete copies of all such Material Contracts.

(j) Third Party Payor Contracts. Schedule 6.1(j) sets forth an accurate and complete list of the ten largest third party payors, in terms of revenue generation for the

(n) Medicare and Medicaid. To the knowledge of PDHC and ADPI, neither PDHC nor ADPI nor any employee or other agent of PDHC or ADPI has violated, in any material respect, any law, statute, rule, regulation, or order under or relating to Medicare, Medicaid, or any other governmental health care reimbursement program, including without limitation those relating to fraud and abuse (the “Governmental Reimbursement Laws”) in any way relative to the Business.

(o) No Broker. No ADPI Party has any obligation to pay any fees or commissions to any broker, lender or investment bankers with respect to the transactions contemplated by this Agreement.

Without limited the indemnifications expressly set forth elsewhere in this Agreement or the other Settlement Documents, PDG and Dental Specialists shall, jointly and severally, indemnify and hold harmless ADPI Parties from and against any and all Damages asserted against, resulting to, imposed upon, or incurred or suffered by the ADPI Parties, directly or indirectly, as a result of or arising from:

8.3. Procedure for Indemnification with Respect to Claims by Third Parties.

(a) If an Indemnified Party desires to seek indemnification under this Article (an “Indemnified Party”) with respect to a claim for which such party is entitled to

indemnification under Section 8.1 or 8.2 and such claim was asserted or instituted by a third party (an “Indemnifiable Claim”), it shall give notice to the other party (“Indemnifying Party”) within a reasonable period of time of the Indemnified Party’s becoming aware of any such Indemnifiable Claim, which notice shall set forth a summary of such material information with respect to such Indemnifiable Claim as is then reasonably available to the Indemnified Party. If any Indemnifiable Claim is asserted against an Indemnified Party and the Indemnified Party notifies the Indemnifying Party of such Indemnifiable Claim, the Indemnifying Party shall be entitled, if the Indemnifying Party so elects by written notice delivered to the Indemnified Party within a reasonable period of time (not to exceed 10 days in any event) after receiving the Indemnified Party’s notice (the “Response Period”), to assume the defense of such Indemnifiable Claim with counsel reasonably satisfactory to the Indemnified Party. Notwithstanding the foregoing: (i) the Indemnified Party shall not have any obligation to give any notice of any Indemnifiable Claim unless the assertion of liability with respect thereto is in writing; (ii) the rights of the Indemnified Party to be indemnified in respect of Indemnifiable Claims shall not be adversely affected by its failure to give notice pursuant to the foregoing provisions unless, and, if so, only to the extent that, the Indemnifying Party is materially prejudiced by such failure; and (iii) each Party shall cooperate with any other Party in all ways reasonably requested by such other Party in connection with the defense of any such Indemnifiable Claims. With respect to any Indemnifiable Claim, the Parties shall make available to each other all relevant information in their possession which is material to any such Indemnifiable Claim.

(b) In the event that the Indemnifying Party fails to assume the defense of the Indemnified Party against any Indemnifiable Claim within the Response Period, the Indemnified Party shall have the right to defend, compromise or settle such Indemnifiable Claim on behalf, for the account, and at the risk of the Indemnifying Party.

(c) Notwithstanding anything in this Section 8.3 to the contrary: (i) if there is a reasonable probability that an Indemnifiable Claim may materially and adversely affect an Indemnified Party or its subsidiaries or other affiliates, other than as a result of money damages or other money payments, then the Indemnified Party shall have the right, at its own cost and expense, to participate in the defense, negotiation, and settlement of such Indemnifiable Claim; and (ii) the Indemnifying Party shall not, without the Indemnified Party’s prior written consent, settle or compromise any Indemnifiable Claim or consent to entry of any judgment in respect of any Indemnifiable Claim unless such settlement, compromise, or consent includes as an unconditional term the giving by the claimant or the plaintiff to the Indemnified Party (and its subsidiaries and other affiliates) of a release from all liability in respect of such Indemnifiable Claim.

8.4. Procedure Involving Direct Claims. The provisions of Section 8.3 are not intended to apply to any claim one Party may have directly against another Party when such claim is not asserted or initiated by a third party. Rather, any such direct claim for indemnification under Sections 8.1 or 8.2 shall be resolved by the Parties pursuant to Section 8.5 or as otherwise agreed to by the Parties concerned.

8.5. Disputes.

(a) Both PDG Parties and ADPI Parties shall at all times have one person appointed as its representative (a “Dispute Representative”) to work in good faith with the Dispute Representative from the other Party to resolve any and all disputes between the Parties arising with respect to the Settlement Agreement, this Agreement, the Transition Services Agreement, or any other Settlement Document (as such term is hereinafter defined) (“Disputes”).

(b) All Disputes that are not resolved by agreement of the Parties or the Dispute Representatives shall be submitted to the Special Master for resolution through binding arbitration. The Parties acknowledge and agree that the jurisdiction of the Special Master shall survive the dismissal of the Action and the expiration of the Transition Period. The fees and expenses of the Special Master shall be divided equally between the ADPI Parties and PDG Parties. Any decision by the Special Master shall be binding on all Parties and may be enforced by a court of competent jurisdiction.
