AMENDED AND RESTATED

SERVICE AGREEMENT

This Amended and Restated Service Agreement (the
Agreement) is made effective January 1, 2009, among Northland Dental Partners, PLLC, a Minnesota professional limited liability company, fka James Ludke, D.D.S., PLLC (Northland), its wholly owned subsidiaries, Family
Periodontic Specialists, P.L.C., Family Oral Surgery Specialists, PLC, and Family Endodontic Specialists, PLC, all Minnesota professional limited liability companies (the Subsidiaries, and with Northland, collectively
Provider), and PDHC, Ltd., a Minnesota corporation (Service Company).

Background Information

A. Provider operates dental practices providing dental services to the general public in and around the Minneapolis, Minnesota area
through individual dentists who are licensed to practice dentistry in the State of Minnesota and who are employed or otherwise retained by Provider.

B. Service Company is engaged in the business of providing assets, personnel, and services to dental practices, other than such services as are directly related to or would improperly influence the provision of dental
care or the practice of dentistry. Service Companys services are intended to permit the dentists in such practices to focus their efforts primarily on rendering quality dental care.

C. Prior to December 31, 2008, Northland was the sole member in Metro Dentalcare, P.L.C., a Minnesota professional limited liability
company (Metro), and Metro was the sole member in each Subsidiary. On December 31, 2008, Metro was merged with and into Northland, with the result that, among other things, Northland is now the sole member in each Subsidiary.

D. Metro, the Subsidiaries, and Metropolitan Dental Management, Inc., a Minnesota corporation (MDMI), are the
parties to a Service Agreement dated September 25, 2007 (the Metro Service Agreement). Metro, the Subsidiaries, and MDMI have terminated the Metro Service Agreement as of the date of this Agreement.

E. Northland and Service Company are the parties to a Service Agreement dated January 1, 2008 (the Original Agreement),
pursuant to which Provider engaged Service Company to provide such services as are necessary and appropriate for the day-to-day administration of the non-clinical aspects of Providers dental practice.

F. Northland desires to continue focusing its energies, expertise and time on the practice of dentistry and on the delivery of dental
services to patients. Northland also desires to have Service Company provide its services to the dental practice formerly operated by Metro, which is now part of Northlands practice, and to the dental practices operated by the Subsidiaries. As
a result, Provider and Service Company (the Parties) desire to amend and restate the Original Agreement to provide for Service Company to provide its services to all of Providers dental practices, all as set forth in this
Agreement.

Company as its sole and exclusive provider of the Services, and Service Company hereby accepts such engagement, subject at all times to the provisions of this Agreement.

2.2 Authority. Service Company shall have all power, authority, and responsibility reasonably necessary to provide the Services and carry out Service Companys other obligations under
this Agreement. Without limiting the foregoing, Service Company shall have the authority to provide the Services in any reasonable manner Service Company deems appropriate to meet the day-to-day requirements of the business functions of Provider.
Provider shall give Service Company 30 days prior written notice of Providers intent to execute any agreement obligating Provider to perform Dental Care or otherwise creating a binding legal obligation on Provider. Unless an expense is
expressly designated as a Service Company Expense in this Agreement, all expenses incurred by Service Company in providing Services pursuant to this Agreement shall be Clinic Expenses.

2.3 Patient Referrals. The Parties agree that the benefits to Provider hereunder do not require, are not payment for, and are not
in any way contingent upon the referral, admission, treatment, or any other arrangement for the provision of any item or service offered by Service Company to patients of Provider in any facility, laboratory, or dental care operation controlled,
managed, or operated by Service Company. Likewise, the Parties agree that Service Company is not engaging, does not intend to engage, and is not required to engage in any referrals of patients to Provider or any similar activities, and neither the
Service Fee nor any other amount paid to Service Company by Provider pursuant to this Agreement is being paid as consideration for or in connection with any such activities.

2.4 Internal Management of Provider. Matters involving the tax planning, investment planning, and internal management, control, or finances of Provider, including without limitation the
compensation of dentists employed or retained by Provider, shall remain the sole and exclusive responsibility of Provider and its members.

The operations of Northland and the Subsidiaries, as Provider under this Agreement, shall to the extent practicable be treated as one operation for purposes of this Agreement, including without limitation for purposes
of budgeting. Northland and the Subsidiaries shall be jointly and severally liable for all of Providers obligations to Service Company under this Agreement. However, Northland shall have the sole responsibility and authority for all decisions,
consents, appointments, and other actions (hereinafter simply actions) to be made, taken, or given by Provider pursuant to or in connection with this Agreement, and each Subsidiary hereby irrevocably appoints Northland as such

absolute right to rely on all such actions taken by Northland.

2.5 Practice of Dentistry. The Parties acknowledge and agree that:
(a) Service Company is not authorized or qualified to engage in any activity that may be construed or deemed to constitute the practice of dentistry; and (b) notwithstanding anything in this Agreement to the contrary: (i) Provider,
through its dentists, shall be solely responsible for and shall have complete authority, responsibility, supervision, and control over the provision of all Dental Care and that all Dental Care shall be provided and performed exclusively by or under
the supervision of dentists as such dentists, in their sole discretion, deem appropriate, consistent with applicable law; (ii) Service Company shall not have or exercise any control or supervision over the provision of Dental Care; and
(iii) to the extent any act or service required of Service Company under this Agreement is reasonably likely to be construed by a court of competent jurisdiction or by any applicable governmental agency to constitute the practice of dentistry,
the requirement to perform that act or service by Service Company shall be deemed waived and unenforceable. For purposes of this Agreement and as the context permits, the term dentist shall be deemed to include those individuals licensed
by the Minnesota Board of Dentistry to practice general dentistry or a dental care specialty such as orthodontics, endodontics, periodontics, prosthodontics, pediatric dentistry, oral surgery, public health dentistry, and oral pathology.

ARTICLE III

POLICY BOARD

3.1 Formation and Operation of Policy Board. The Parties hereby establish a policy board (the Policy
Board) which shall be responsible for developing and implementing management and administrative policies for the overall operation of Clinics, subject to Section 3.3, below. The Policy Board shall initially consist of six members, of
which three members shall be designated by Service Company, in its sole discretion, and three members shall be designated by Provider, in its sole discretion; provided that, unless otherwise agreed by the Parties the Policy Board members designated
by Provider shall be licensed dentists employed by Provider. Each Party shall have the right to designate, remove, and replace its Policy Board designees at any time and from time to time upon notice to the other Party.

Any decision made by a Partys Policy Board representatives shall be binding on that Party. Except as may otherwise be expressly
provided in this Agreement or any rules, bylaws, or regulations adopted by the Policy Board, the act of a majority of the members of the Policy Board shall be the act of the Policy Board. The Policy Boards decisions may be evidenced by either
minutes of a Policy Board meeting or written action taken by the Policy Board members making the decision; provided that no written action signed by less than all of the Policy Board members shall be effective unless notice of such action is given
to each Policy Board member who is not signing such action at least two business days prior to the effective date of such action. The decisions, resolutions, actions or recommendations of the Policy Board within its authority shall be implemented by
Service Company or Provider, as appropriate.

The Policy Board shall hold regular meetings at such places and at such times
(not less often than quarterly) as the Policy Board may determine from time to time. Special Policy Board meetings may be called by either Party or any two Policy Board members; provided that notice of any meeting which is not a regularly scheduled
meeting shall be given to all Policy Board members at least five business days prior to the meeting, unless such notice is waived by the Policy Board members. Policy Board meetings may be held through the use of remote communications equipment so
long as all members can participate with each other clearly during the meeting.

arrangements, preferred provider organization discounts and capitated fee arrangements, shall be subject to the review and recommendations of the Policy Board. Where there is no clear methodology for the allocation of capitated fees among

capitation arrangement.

approve the long-term strategic and short-term operational goals, objectives and plans developed by Service Company.

provided that the costs and expenses of any repairs, maintenance and replacement necessitated by the negligence or willful misconduct of dentists or other personnel employed or otherwise retained by Provider shall be a Provider Expense, but one that

appropriateness, and necessity of Dental Care provided by Provider, and shall provide administrative support for Providers overall quality assurance, risk management, and utilization review programs. Service Company shall have the authority to
monitor Providers level of conformance with such procedures and to report its findings to Provider.

4.8 Licenses
and Permits. Although Provider shall be solely responsible for obtaining and maintaining all federal, state, and local licenses and regulatory permits required for or in connection with the operation of Provider and in connection with the
operation of all dental equipment located in each Clinic, Service Company shall assist Provider with the implementation of a plan designed to ensure that all such licenses and permits are obtained and shall provide reasonable assistance to Provider
in obtaining the same. Service Company also shall maintain all licenses and permits required for all equipment (existing and future) located at each Clinic.

4.9 Personnel. Except as provided in Section 5.2(d) of this Agreement and subject to Section 3.3: (a) Service Company shall employ or otherwise retain and shall be
responsible for recruiting, hiring, and terminating all management, administrative, supervisory, clerical, secretarial, bookkeeping, accounting, and payroll personnel, laboratory technicians and personnel, dental hygienists, dental assistants, and
other non-dentist personnel as Service Company deems necessary and appropriate for Service Companys performance of its duties and obligations under this Agreement; and (b) the selection, training and supervision of all such personnel to

shall advise Provider with respect to and negotiate, either directly or on Providers behalf, as appropriate, such contractual arrangements with third parties as are reasonably necessary and appropriate for Providers provision of Dental
Care, including without limitation negotiated price agreements with third party payors, alternative delivery systems, or other purchasers of group dental care services; provided that no contract or arrangement regarding the provision of Dental Care

4.11 Billing and Collection. On behalf of and for the account of
Provider, Service Company shall establish and maintain credit and billing and collection policies and procedures, and shall exercise reasonable efforts to bill and collect in a timely manner (and to the extent permitted by applicable law) all
professional and other fees for all billable Dental Care provided by Dental Care Professionals. Service Company shall advise and consult with Provider regarding the fees for Dental Care provided by Provider (including any related discounting
policy), it being understood, however, that Provider shall establish the fees (subject to Section 3.2(d), above) to be charged for Dental Care and that Service Company shall have no authority whatsoever with respect to the establishment of such
fees. In connection with the billing and collection services to be provided hereunder, Provider hereby grants to Service Company, to the extent permitted by applicable law, throughout the Term (and thereafter as provided in Section 8.3), an
exclusive special power of attorney and appoints Service Company, to the extent permitted by applicable law, as Providers exclusive true and lawful agent and attorney-in-fact, and Service Company hereby accepts such special power of attorney
and appointment, for the following purposes:

(a) To bill Providers patients, in Providers name
and on Providers behalf, for all billable Dental Care provided by or on behalf of Provider to patients.

(b) To bill, in Providers name and on Providers behalf, all claims for reimbursement or indemnification from insurance companies and plans, all state or federally funded dental benefit plans, and all other third party payors or
fiscal intermediaries for all covered billable Dental Care provided by or on behalf of Provider to patients.

(c) To collect and receive, in Providers name and on Providers behalf, all accounts receivable generated by such billings and claims for reimbursement, to administer such accounts including, but not limited to, extending the
time of payment of any such accounts for cash, credit or otherwise; discharging or releasing the obligors of any such accounts; suing, assigning or selling at a discount such accounts to collection agencies; or taking other measures to require the
payment of any such accounts; provided, however, that extraordinary collection measures, such as filing lawsuits, discharging or releasing obligors, or assigning or selling accounts at a discount to collection agencies shall not be undertaken
without Provider Consent.

(d) To deposit all amounts collected into the Provider Account which shall be and
at all times remain in Providers name. Provider shall transfer and deliver to Service Company all funds received by Provider from patients or third party payors for Dental Care. Upon receipt by Service Company of any funds from patients or
third party payors or from Provider for Dental Care pursuant to this Agreement, Service Company shall promptly deposit the same into the Provider Account.

Provider Account for payments specified in this Agreement and as requested from time to time by Provider.

(g) To designate, remove, and change such signatories on the Provider Account as Service Company deems necessary or appropriate from time to time.

Upon request of Service Company, Provider shall execute and deliver to the financial institution at which the Provider Account is maintained such additional documents or instruments as Service
Company may reasonably request to evidence or effect the special power of attorney granted to Service Company by Provider pursuant to this section and Section 4.12. The special power of attorney granted herein is coupled with an interest and
shall be irrevocable except with Service Companys written consent. The irrevocable power of attorney shall expire when this Agreement has been terminated, all accounts receivable purchased by Service Company pursuant to Section 7.6, if
any, have been collected, and all amounts due to Service Company as described in Article VII have been paid.

4.12
Provider Account

(a) Power of Attorney. Service Company shall have access to the Provider
Account solely for the purposes stated herein and shall use all funds on deposit therein in accordance with the terms of this Agreement. Provider hereby grants to Service Company an exclusive special power of attorney and appoints Service Company as
Providers true and lawful agent and attorney-in-fact, throughout the Term (and thereafter as provided in Section 8.3), and Service Company hereby accepts such special power of attorney and appointment, to make withdrawals from the
Provider Account for: (i) payments described in this Agreement; and (ii) such other purposes as Service Company deems appropriate (consistent with this Agreement), including without limitation daily transfers to one or more accounts owned
by Service Company or its affiliates as part of cash management procedures established or adopted by Service Company or its affiliates from time to time; provided that to the extent that the aggregate funds withdrawn by Service Company from the
Provider Account pursuant to this section (the Aggregate Withdrawals) exceed the aggregate amounts paid or payable to Service Company under this Agreement (the Aggregate Payments), then such excess shall be deemed to be held
by Service Company as agent for Provider. Notwithstanding this exclusive special power of attorney, Provider may, upon reasonable advance notice to Service Company, request that Service Company draw checks on the Provider Account for Provider
Expenses and such other amounts as may be due to Provider under this Agreement, subject to Section 4.12(b) of this Agreement.

(c) Further Assurances. Promptly upon request by Service Company, Provider shall
execute a separate power of attorney in form reasonably satisfactory to Service Company for the purpose of further confirming or evidencing the rights granted to Service Company under Sections 4.11 and 4.12.

4.13 Financial Matters

(a) Annual Budget. At least 30 days prior to the commencement of each calendar year, Service Company, in consultation with Provider, shall prepare and deliver to the Policy Board for its
review and approval a proposed Budget, setting forth an estimate of Providers revenue and expenses for the upcoming calendar year (including without limitation the Service Fee associated with the services provided by Service Company
hereunder).

In the event that a proposed Budget is not approved by either the Policy Board or Parent
(pursuant to Section 3.2(b)), Service Company, in consultation with Provider, shall promptly revise such Budget, taking into consideration the comments of the Policy Board or Parent, as applicable, and shall deliver such revised Budget to the
Policy Board for approval. In the event that a proposed Budget has not been approved by both the Policy Board and Parent by the beginning of the calendar year, then, until a new Budget has been approved by both the Policy Board and Parent, the
Budget for the prior year shall be deemed to be adopted as the Budget for the then-current year except that (i) the Budget for Clinic Expenses shall be adjusted to account for any changes beyond the reasonable control of Service Company,
including without limitation changes in laboratory fees or supply costs and automatic increases in rent or other occupancy costs, (ii) Service Company shall have the right to adjust the Budget for reasonable compensation increases for its
employees, for changes in employee benefits or related costs, and for expenses related to new employees reasonably necessary for Service Company to perform the Services, and (iii) the Budget for capital expenditures shall include only
expenditures for maintenance or emergency needs and any other capital expenditures expressly approved by both the Policy Board and Parent from time to time.

Notwithstanding any provisions of this Agreement to the contrary, for purposes of all calculations related to the Service Fee for any period the amount of Provider Expense used in such
calculations for that period shall be determined by applying the methodology for compensating dentists and paying other budgeted Provider Expenses contained in the then-applicable Budget (e.g., if the Budget requires a dentist to be paid a base
salary, that salary shall be used for purposes of such calculations, and if the Budget requires that a dentist be paid formula-based compensation, that formula shall be used for purposes of such calculations); provided that the Parties shall
exercise reasonable efforts to adjust the Budget from time to time as necessary to

other financial statements or records as Provider may reasonably request.

5.2 Provider Personnel

(a) Dentist Personnel. Provider shall retain, as a Provider Expense and not as a Clinic Expense, that number of
dentists during the Term which are necessary and appropriate, in Providers sole discretion, to provide Dental Care to reasonably meet the demand therefor. Provider shall cause each dentist retained by Provider to hold and maintain a valid and

Dental Care coverage, Provider shall engage and retain dentists on a temporary coverage basis, which dentists shall meet or exceed the qualifications required for Providers Dental Care Professionals under this Agreement. All costs and expenses
associated with the retention of such temporary coverage shall be Provider Expenses. With the assistance of the Service Company, Provider and the dentists shall be responsible for scheduling dentist and non-dentist dental care personnel coverage of

resolve dental competency issues. The dental peer review committee shall function pursuant to formal written policies and procedures established by Provider
upon consultation with and assistance of Service Company.

(b) Provider also shall adopt a quality assurance
program to monitor and evaluate the quality and cost-effectiveness of the Dental Care provided by Providers dentists and by non-dentist personnel providing Dental Care under the supervision of Providers dentists. Upon request of

5.6 Providers Insurance.

insurance or some combination thereof (reasonably acceptable to Service Company) appropriate workers compensation coverage for Providers employed personnel (which, with respect to dental hygienists and other non-dentist licensed dental
personnel employed by Provider, shall be a Clinic Expense, and which, with respect to all other employees of Provider, including without limitation dentists, shall be a Provider Expense) and professional liability and comprehensive general liability
insurance covering Provider and each of the dentists, dental hygienists, and other licensed dental personnel Provider retains to provide Dental Care (which, including any applicable deductibles, shall be a Clinic Expense). All costs, expenses, and
liabilities incurred by Provider or Service Company in excess of the limits of such policies shall be a Provider Expense. Provider shall actively support the participation of all dentists, dental hygienists, and other licensed dental personnel
retained by Provider in training and continuing education programs in order to reduce the risk of exposure to and the related cost of obtaining and maintaining such coverage. The comprehensive general liability coverage and professional liability
coverage shall be in such



15



---

minimum amounts and with such deductibles as Service Company may establish from time to time. In addition, Provider shall cause each dentist retained by
Provider as an independent contractor to obtain comparable professional and comprehensive general liability insurance coverage.

(b) All such insurance policies shall (a) name Service Company as an additional insured and with respect to policies provided by independent contractors under the preceding sentence, name Provider as additional
insured as well, and (b) provide for at least 30 days advance written notice to Provider and Service Company from the insurer with respect to any alteration of coverage, cancellation, or proposed cancellation for any reason. Provider shall
cause to be issued to Service Company by such insurer or insurers a certificate reflecting such coverage.

(c) Provider shall enter into employment or other agreements with all dentists employed or otherwise retained by Provider which provide, among other things, that (i) upon the termination of the employment or retention of any such
dentist, such dentist shall be required to (A) purchase, at such dentists expense, tail professional liability coverage meeting the requirements of this §5.6, including without limitation those relating to coverage
amounts and insureds, for an unlimited extended reporting period, or (B) obtain retroactive coverage meeting the same requirements from such dentists new employer, and (ii) if such dentist does not provide satisfactory evidence of
such coverage prior to such termination, Provider shall have the right, without limiting any other rights of Provider, to withhold the cost of the tail coverage described in the immediately preceding clause (i)(A) from any amounts owed
to such dentist by Provider and purchase such tail coverage on such dentists behalf; provided that if Provider does not have such agreements in place with dentists employed or otherwise retained by Provider as of the date of
execution of this Agreement, Provider shall not be in breach of this Agreement so long as it (1) exercises commercially reasonable efforts to enter into such agreements with the dentists currently employed or retained by Provider, and
(2) enters into such agreements with all new dentists employed or retained by Provider.

(d) Upon the
termination of this Agreement for any reason, Provider shall continue to carry professional liability insurance in the amounts specified in this §5.6 for 10 years after termination, or, if Provider dissolves or ceases to practice dentistry,
Provider shall obtain and maintain as a Provider Expense tail professional liability coverage in the amounts specified in this §5.6 for an unlimited extended reporting period. Provider shall be responsible for paying all premiums
for such tail insurance coverage. Notwithstanding the foregoing, if Provider fails to obtain such tail insurance coverage, Service Company shall have the right, without limiting any other rights of Service Company, to
purchase such coverage on Providers behalf out of funds otherwise owed to Provider under this Agreement.

(e) In no event shall a professional liability insurance carrier be replaced or changed without Service Company Consent. Service Company shall provide reasonable assistance to Provider to obtain the insurance coverages described in this
§5.6.

(f) Each Party shall, and shall cause it employees, agents, and other representatives to,
cooperate in all ways reasonably requested by the other Party in connection with the handling and disposition of claims covered by the insurance described in this §5.6. This requirement shall continue, notwithstanding any termination of this
Agreement, until all such claims have been resolved.

5.7 Noncompetition. Provider acknowledges that Service Company will incur
substantial costs in providing the equipment, support services, personnel, and other items and services that are the subject matter of this Agreement and that in the process of providing services under this Agreement, Provider will learn or have
access to financial and other Confidential Information of Service Company to which Provider would not otherwise be exposed. Provider also recognizes that the services to be provided by Service Company will be feasible only if Provider operates an
active practice to which the dentists associated with Provider devote their full time and attention. Accordingly, Provider further agrees as follows:

(a) During the Term, except for any Clinic or other office or facility covered by this Agreement, Provider shall not establish, operate, or provide Dental Care at any dental office, clinic or
other dental care facility anywhere within the Practice Territory nor have any ownership interest, direct or indirect, in any entity, or participate in any joint venture, which operates any such office, clinic or facility; and

(b) Except as specifically approved by Service Company in writing, during the Term and for a period of five years

control, lend funds to, lend its name to, maintain any interest in, or otherwise enter into, engage in, or promote or assist (financially or otherwise) any entity, business, or enterprise which (i) provides, distributes, or promotes any type of
management or administrative services or products to third parties in competition with Service Company in the Practice Territory, or (ii) offers any type of service or product to third parties substantially similar to those offered by Service
Company to Provider in the Practice Territory. Notwithstanding the above restriction, nothing herein shall prohibit Provider or any of its members from providing management and administrative services to its or their own dental practices after the
termination of this Agreement, and nothing herein shall prohibit Provider or its members from contracting with a third party manager to provide administrative or management services for its or their dental practices after termination of this
Agreement as long as such relationship complies with the provisions of this section.

ARTICLE VII

FINANCIAL ARRANGEMENTS

7.1 Clinic Expense Reimbursement. Service Company shall be reimbursed for the amount of all Clinic Expenses incurred by Service Company.



18



---

7.2 Repayment of Advances. Service Company shall be reimbursed for any and all
amounts advanced to Provider by Service Company pursuant to the terms and conditions of this Agreement.

7.3 Service
Fee. Provider and Service Company acknowledge and agree that the compensation set forth in this Article is being paid by Provider to Service Company in consideration of the substantial commitment being made by Service Company hereunder and that
such fee is fair and reasonable in all respects in consideration of (a) the services performed by Service Company hereunder, and (b) the capital being made available by Service Company. Service Company shall be paid by Provider an annual
Service Fee (determined on a calendar year basis) equal to 89% of the Calculated Margin, which shall be calculated and be earned and accrue daily, and shall be payable monthly.

7.4 Reasonable Value. Payment of the Service Fee is not intended to be and shall not be interpreted or applied as permitting Service Company to share in Providers fee for Dental Care
or any other services, but is the Parties negotiated agreement as to the reasonable fair market value of the equipment, contract analysis and support, other support services, purchasing, personnel, office space, management, administration,
strategic management, and other items and services furnished by Service Company pursuant to this Agreement, considering the nature and volume of the services required and the risks assumed by Service Company. Provider and Service Company acknowledge
that: (a) Service Companys administrative expertise will contribute great value to Providers performance; (b) Service Company will incur substantial costs and business risks in arranging for Providers use of each Clinic
and in providing the equipment, support services, personnel, marketing, office space, management, administration, and other items and services that are the subject matter of this Agreement; and (c) certain of such costs and expenses can vary to
a considerable degree according to the extent of Providers business and services. It is the intent of the Parties that the Service Fee reasonably compensate Service Company for the value to Provider of Service Companys administrative
expertise, given the considerable business risk to Service Company in providing the items and services that are the subject of this Agreement.

7.5 Payment. The amounts to be paid to Service Company under this Article shall be paid monthly. To facilitate the payments due to Service Company under this Article, Provider hereby expressly authorizes
Service Company to make withdrawals of such amounts from the Provider Account during the Term in accordance with Section 4.12(b), and after termination as provided in Section 8.3.

7.6 Accounts Receivable. To assure that Provider receives the entire amount of professional fees for its services and to assist
Provider in maintaining reasonable cash flow for the payment of Clinic Expenses, Service Company may, during the Term, purchase, with recourse to Provider for the amount of the purchase, the accounts receivable of Provider arising during the
previous month, except for any receivables due to Provider from Medicaid or any other governmental health care reimbursement program which Service Company is not permitted to receive under applicable law (the Restricted Receivables), by
transferring the amount set forth below into the Provider Account. The consideration for the purchase shall be an amount equal to the Adjusted Gross Revenue recorded each month, less the Adjusted Gross Revenue related to Restricted Receivables.
Service Company shall be entitled to offset Clinic Expense reimbursement plus all fees and advances due to Service Company under this Article against the amount payable for such accounts receivable. Although it is the intention of the Parties that
Service Company purchase and thereby become the owner of the accounts receivable of Provider, in the event such purchase shall be ineffective or prohibited for any reason, Provider hereby



19



---

grants to Service Company a security interest in the accounts receivable, to the extent permitted by applicable law, and Provider shall cooperate with
Service Company and execute all documents which may be reasonably requested by Service Company in connection with such security interest. All collections in respect of such accounts receivable purchased by Service Company shall be received by
Provider as the agent of Service Company and shall be endorsed to Service Company and deposited in a bank account at a bank designated by Service Company. To the extent Provider comes into possession of any payments in respect of such accounts
receivable, Provider shall direct such payments to Service Company for deposit in bank accounts designated by Service Company.

All costs and expenses of arbitration shall be borne by the Parties as determined by the arbitrator or arbitration panel,
except that the fees of any arbitrator on an arbitration panel who is selected individually by a Party shall be borne separately by the Party appointing him; provided that if one Party fails to select an arbitrator for a panel, and the sole
arbitrator is the arbitrator selected by the other Party, then the fees of that arbitrator shall be borne by the Parties as determined by that arbitrator.

8.3 Effects of Termination. Upon termination of this Agreement as herein provided, neither Party shall have any further obligations under this Agreement, except for: (a) obligations accruing prior to the
date of termination, including without limitation payment of the amounts set forth in Article VII relating to services provided prior to the termination of this Agreement; (b) obligations set forth in this Agreement that expressly extend beyond
the Term, including without limitation indemnities and noncompetition provisions, which provisions shall survive the expiration or termination of this Agreement; (c) the obligations of each Party set forth in Article VI; and (d) the
obligation of Provider described in Section 8.4. Provider specifically acknowledges and agrees that Service Company shall continue to collect and receive on behalf of Provider all cash collections from accounts receivable in existence at the
time this Agreement is terminated (which have not otherwise been purchased by Service Company pursuant to Section 7.6), and that all such cash collections shall be disbursed in accordance with Section 4.12(b), it being understood that such
cash collections will represent, in part, compensation to Service Company for Services already rendered and compensation on accounts receivable purchased by Service Company, if any. Upon the expiration or termination of this Agreement for any reason
or cause whatsoever, Service Company shall surrender to Provider all books and records pertaining to Providers dental practice; provided that Service Company may retain copies of such documents to the extent reasonably necessary for Service
Company to complete its post-termination obligations and activities under this Agreement.

8.4 Purchase Obligation.
Upon termination of this Agreement for any reason Provider shall, at Service Companys option (subject to any consent rights of Parents senior creditor):

(a) Purchase from Service Company at book value the intangible assets, deferred charges, goodwill, and all other amounts
on the books of the Service Company relating to this Agreement or the items or services provided by Service Company pursuant to this Agreement, including without limitation the amount, if any, for the covenants described in Section 5.7, above,
as adjusted through the last day of the month most recently ended prior to the date of such termination in accordance with GAAP to reflect amortization or depreciation of all such amounts, provided the foregoing shall not apply to any trade names,
trademarks, service marks, or similar items owned by Service Company or its affiliates and used at any time during the term of this Agreement in connection with the operation of Providers dental practice (the Marks);

(b) Purchase from Service Company any real estate owned by Service Company and used as a Clinic at the greater of the

---

(c) Purchase, at the greater of the appraised fair market value or the
then book value, all improvements, additions, or leasehold improvements that have been made by Service Company at any Clinic and that relate to the performance of Service Companys obligations under this Agreement;

(d) Assume all debt, and all contracts, payables, and leases that are obligations of Service Company and that relate to
the performance of Service Companys obligations under this Agreement or the properties leased or subleased by Service Company in connection with its obligations under this Agreement;

(e) Purchase from Service Company, at the greater of the appraised fair market value or the then book value, all of the
equipment then being supplied by Service Company pursuant to Service Companys obligations under this Agreement, and all other assets, including inventory and supplies, tangibles and intangibles (other than the Marks), set forth on the books of
Service Company as adjusted through the last day of the month most recently ended prior to the date of such termination in accordance with GAAP to reflect operations of each Clinic, depreciation, amortization, and other adjustments of assets shown
on the books of the Service Company; and

(f) Purchase from Service Company, at the greater of appraised
fair market value or then book value, all Marks designated by Service Company.

For purposes of subsections (b), (c), (e),
and (f) above, the appraised value shall be determined by an appraiser mutually agreed upon by the Parties. In the event the Parties are unable to agree upon an appraiser within 10 days following the date upon which either Party requests the
other Party to agree to an appraiser, then each Party shall appoint an appraiser, who shall in turn select a third appraiser who shall serve as the appraiser hereunder. In the event either Party fails to select an appraiser within 15 days of the
selection of an appraiser by the other Party, the appraiser selected by the other Party shall serve as the appraiser hereunder. The determination of the appraised value of the assets identified in such subsections, by the appraiser or appraisers
selected hereunder shall be binding on both Parties.

8.5 Closing of Purchase. If Provider purchases assets pursuant
to Section 8.4, Provider shall pay cash for the purchased assets; provided that the amount of the purchase price allocable to an asset shall be reduced by the amount of debt and liabilities of Service Company, if any, relating directly to that
asset which are assumed by Provider in connection with such purchase. Any asset which is purchased by Provider pursuant to Section 8.4 and with respect to which the purchase price reduction described in the preceding sentence does not apply
shall be transferred to Provider free and clear of all liens and encumbrances at closing. Provider and any dentist associated with Provider shall execute such documents as may be required for Provider to assume the liabilities set forth in
Section 8.4(d) and to remove Service Company from any liability with respect to such purchased asset and with respect to any property leased or subleased by Service Company. The closing date for the purchase shall be determined by the Parties
but shall in no event occur later than 180 days from the date of the notice of termination. Provider shall be released from the covenants described in Section 5.7, above, upon the successful consummation of such closing.

ARTICLE IX

GENERAL

9.1 Nature of Services. Nothing in this Agreement is intended
or shall be construed to allow Service Company to exercise control or direction over the manner or method by which Provider and its dentists or the dental hygienists and other licensed dental personnel and unlicensed dental assistants and other
personnel supervised by Provider or its dentists, perform Dental Care or other professional dental care services. The rendition of all Dental Care shall be the sole responsibility of Provider and its dentists and the dental hygienists and other
licensed dental personnel and unlicensed dental assistants supervised by Provider and its dentists, and Service Company shall not interfere in any manner or to any extent therewith. Nothing contained in this Agreement shall be construed to permit
Service Company to engage in the practice of dentistry, it being the sole intention of the Parties hereto that the services to be rendered to Provider by Service Company are solely for the purpose of providing non-dental administrative and
management services to Provider so as to enable Provider to devote its full time and energies to the professional conduct of its dental practice and provision of Dental Care to its patients and not to administration or practice management.

9.2 Relationship of Parties. The relationship of the Parties is and shall be that of independent contractors, and
nothing in this Agreement is intended, and nothing shall be construed, to create an employer/employee, partnership, or joint venture relationship between the Parties, or to allow either to exercise control or direction over the manner or method by
which the other performs the services that are the subject matter of this Agreement; provided always that the services to be provided hereunder shall be furnished in a manner consistent with the standards governing such services and the provisions
of this Agreement.

Any Party may change the address to which notices and other communications are to
be given by giving the other Party notice of such change.

9.4 Execution of Documents. Each Party shall execute,
acknowledge or verify, and deliver any and all documents, and take any and all other actions, which from time to time may be reasonably requested by the other Party to carry out the purposes and intent of this Agreement.

9.5 Governing Law. All questions concerning the validity, intention, or meaning of this Agreement or relating to the rights and
obligations of the Parties with respect to performance under this Agreement shall be construed and resolved under the laws of Minnesota without reference to conflict of law principles.

9.6 Severability. The intention of the Parties is to comply fully with all applicable laws and public policies, and this Agreement
shall be construed consistently with all laws and public policies to the extent possible. If and to the extent that any court of competent jurisdiction determines that it is impossible to construe any provision of this Agreement consistently with
any law or public policy and consequently holds that provision to be invalid, such holding shall in no way affect the validity of the other provisions of this Agreement, which shall remain in full force and effect. With respect to any provision in
this Agreement finally determined by such a court to be invalid or unenforceable, such court shall have jurisdiction to reform this Agreement (consistent with the intent of the Parties) to the extent necessary to make such provision valid and
enforceable, and, as reformed, such provision shall be binding on the Parties.

appropriate in all respects; and (c) in the event it violates any such provisions, the other Party would suffer irreparable harm and its remedies at law would be inadequate. Accordingly, in the event either Party violates or attempts to violate
any such provisions, the other Party shall be entitled



25



---

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 other Party.

9.9 Non-waiver. No failure by any Party to insist upon strict compliance with any term of this Agreement, to exercise any option, enforce any right, or seek any remedy upon any default of any other Party shall
affect, or constitute a waiver of, the first Partys right to insist upon such strict compliance, exercise that option, enforce that right, or seek that remedy with respect to that default or any prior, contemporaneous, or subsequent default;
nor shall any custom or practice of the Parties at variance with any provision of this Agreement affect or constitute a waiver of, any Partys right to demand strict compliance with all provisions of this Agreement.

9.10 Indemnification. To the extent not covered by and paid from its insurance coverage, each Party (the Indemnifying
Party) shall indemnify and hold harmless the other Party and its shareholders, members, managers, directors, officers, employees, agents, representatives, and affiliates (the Indemnified Parties) from and against any and all
losses, liabilities, damages, demands, claims, suits, actions, judgments, assessments, costs and expenses, including without limitation interest, penalties, attorneys fees, any and all expenses incurred in investigating, preparing, or
defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation (collectively, Damages), asserted against, imposed upon, or incurred or suffered by
the Indemnified Parties, directly or indirectly, as a result of or arising from: (i) any failure of any representation or warranty of the Indemnifying Party in this Agreement to be accurate and complete in all material respects when made; or
(ii) any failure by the Indemnifying Party to perform and observe fully all obligations and conditions to be performed or observed by the Indemnifying Party under this Agreement. In addition, Provider shall indemnify Service Company and its
shareholders, members, managers, directors, officers, employees, agents, representatives, and affiliates from and against any and all Damages asserted against, imposed upon, or incurred or suffered by any of them, directly or indirectly, as a result
of or arising from the acts or omissions of Provider or its employees, contractors, or other agents or representatives.

9.11 No Third Party Benefit. This Agreement is intended for the exclusive benefit of the Parties and their respective successors and assigns, and nothing contained in this Agreement shall be construed as creating any rights or
benefits in or to any third party.

9.12 Captions. The captions of the various sections of this Agreement are not
part of the context of this Agreement, are only labels to assist in locating and reading those sections, and shall be ignored in construing this Agreement.

9.13 Genders and Numbers. When permitted by the context, each pronoun used in this Agreement includes the same pronoun in other genders or numbers and each noun used in this Agreement
includes the same noun in other numbers.

other documents referred to herein, all of which are hereby incorporated herein by reference) contains the entire agreement among the Parties with respect to the subject matter of this Agreement and supersedes all prior or contemporaneous

9.15 Counterparts. This Agreement may be executed in multiple counterparts, each
of which shall be deemed to be an original, but all of which taken together shall constitute one and the same Agreement, and any photocopy, facsimile, or electronic reproduction of the executed Agreement shall constitute an original.

9.16 Assignment. Provider may not assign this Agreement without the prior written consent of Service Company, which consent may be
withheld for any reason. The sale, transfer, pledge, or assignment of any of the membership interests of Provider held by any member of Provider, the issuance by Provider of voting membership interests to any other person, or any combination of such
transactions within any period of two years, such that the members in Provider at the beginning of that two-year period fail to maintain a majority of the voting interest in Provider, shall be deemed an attempted assignment by Provider, and shall be
null and void unless consented to in writing by Service Company prior to any such transfer or issuance. Any breach of this provision, whether or not void or voidable, shall constitute a material breach of this Agreement, and in the event of such
breach, Service Company may terminate this Agreement upon 24 hours notice to Provider. Service Company shall have the right to (i) assign its rights and obligations hereunder to any third party and (ii) collaterally assign its interest in
this Agreement and its right to collect the amounts set forth in Article VII hereunder to any financial institution or other third party without the consent of Provider. Service Company shall notify Provider of any assignment of this Agreement of
the type described in the immediately preceding clause (i).

indirectly, from acts of God, civil or military authority, acts of public enemy, war, accidents, fires, explosions, earthquakes, floods, failure of transportation, strikes or other work interruptions by either Partys employees, or any other
similar cause beyond the reasonable control of either Party unless such delay or failure in performance is expressly addressed elsewhere in this Agreement.

9.19 Interpretation. This Agreement supersedes the Original Agreement in its entirety from and after the date of this Agreement; provided that this Agreement shall not modify or otherwise
affect any rights or obligations of the Parties under the Original Agreement which are based upon acts or omissions occurring prior to the date of this Agreement, which rights and obligations shall survive the execution of this Agreement. If and to
the extent any provision of this Agreement conflicts with the obligations of either Northland or Service Company under the Definitive Settlement Agreement dated February 29, 2008 among Northland, Service Company, PDG, P.A., and Dental
Specialists of Minnesota, P.A., or any other agreement or document executed by either of them pursuant to such Definitive Settlement Agreement, then that Partys obligation to perform or observe such provision of this Agreement shall be
modified to the extent necessary for that Party to be in compliance with such Definitive Settlement Agreement or such other agreement or document.

majority of Providers representatives who serve on the Policy Board. When any provision of this Agreement requires Provider Consent, Provider Consent shall not be unreasonably withheld and shall be binding on Provider.

Provider Expense. The term Provider Expense shall mean any expense (other than an expense for which Provider is
required by applicable law to be financially liable and which is expressly identified in this Agreement as a Clinic Expense) incurred by the Service Company or Provider and for which Provider, and not the Service Company, is financially liable.
Provider Expense shall include dentist (as defined in Section 2.5) salaries, benefits (which includes workers compensation coverage), and other direct costs related to the dentists employed or otherwise retained by Provider for the
provision of its Dental Care (including professional dues, subscriptions, continuing dental education expenses, and travel costs for continuing dental education or other business travel, but excluding business travel requested by Service Company,
which shall be a Clinic Expense), together with any expense related to any Dental Assets or the maintenance or protection of the same and any other cost or expense designated as a Provider Expense in or pursuant to this Agreement. In the event
Provider incurs any consulting, accounting, legal or other similar fee without Service Companys approval of such engagement through Service Company, any fee or expense so incurred shall be a Provider Expense, but one that is ignored for
purposes of calculating the Calculated Margin and therefore must be paid out of Provider Retained Earnings. Any Provider Expense which is not within the then-applicable Budget or the parameters described in the third paragraph of
Section 4.13(a) and is not approved by either the Policy Board or the Service Company shall be ignored for purposes of calculating the Calculated Margin and therefore must be paid out of Provider Retained Earnings. In addition, and
notwithstanding any other provisions of this Agreement or the Initial Agreement to the contrary, the Guaranteed Payments shall not be deemed to be Provider Expenses for purposes of calculating the Calculated Margin and also must be paid out of
Provider Retained Earnings; provided that to the extent Provider Retained Earnings are insufficient for Provider to make the Guaranteed Payments, Service Company shall advance funds to Provider in an amount equal to such insufficiency (which
advances shall be deemed made under Section 7.2).
