SCHEDULE 2



FEES AND EXPENSES



|1. | Hourly Fees
|-- | -----------



Our fees will be based on the hours charged at our hourly rates, which are:



|                            |  |   |           
|--------------------------- |  | - | ----------
|Principals                  |  | $ | 540 - $690
|Senior Associates           |  | $ | 430 - $520
|Associates                  |  | $ | 300 - $400
|Accountants and Consultants |  | $ | 225 - $280
|Analysts                    |  | $ | 150 - $190



|2. | Contingent Success Fee
|-- | ----------------------



In addition to hourly fees, APS will be compensated for its efforts by the payment of a Contingent Success Fee (Success Fee). The Company
understands and acknowledges that the Success Fee is an integral part of APS compensation for the engagement.



Because of the nature of this engagement, it is unclear at this time precisely how to define important elements of the Success Fee criteria. Therefore,
not later than six weeks following the beginning of the engagement, the Company and APS will make a reasonable effort to determine an incentive bonus or Success Fee based upon the value that APS is able to provide to the Company. APS and the Company
mutually agree to develop a definition of success and agreed-upon success fee criteria at within that time. It is anticipated that the level of the Success Fee would not exceed $5,000,000.



|3. | Expenses
|-- | --------



In addition to the fees set forth above, the Company shall pay directly or reimburse APS upon receipt of periodic billings, for all reasonable
out-of-pocket expenses incurred in connection with this assignment such as travel, lodging, postage, and actual telephone and facsimile charges.



|4. | Break Fee
|-- | ---------



APS does not seek a Break Fee on this engagement.





---

SCHEDULE 3



DISCLOSURES



To the best of our knowledge, we believe that APS, its employees, and its affiliates do not have any financial interest or business connection with the Company other than
as contemplated by this agreement, and we know of no fact or situation that would represent a conflict of interest for us with regard to the Company. However, we have not completed a thorough check of the parties in interest with regard to the
Company. Upon receiving the information from the Company with respect to the parties in interest, APS will promptly complete a search of its relationships and will notify you of any connections APS may have with such parties in interest.



The Parties agree that this Schedule 3 may be updated from time to time to disclose
additional connections or relationships between APS and the interested parties.

AP SERVICES, LLC

GENERAL TERMS AND CONDITIONS



These General Terms and Conditions (Terms) shall govern the services provided by AP Services, LLC (APS) as set forth in the letter agreement
executed by the Company and APS to which these Terms are attached.



Section
1. Company Responsibilities



Company will undertake responsibilities as
set forth below:



|1. | Provide reliable and accurate detailed information, materials, documentation, and
|-- | ---------------------------------------------------------------------------------



|2. | Make decisions and take future actions, as the Company determines in its sole discretion, on any recommendations made by APS in connection with the tasks or work product under this
Agreement.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



APS delivery of the services and the fees
charged are dependent on (i) Companys timely and effective completion of its responsibilities; and (ii) timely decisions and approvals made by the Companys management. Company shall be responsible for any delays, additional costs, or
other deficiencies caused by not completing its responsibilities.



Section
2. Timing, Fees, and Expenses.



The engagement will commence immediately
upon receipt of a signed engagement letter and a retainer.



Hourly Fees.For purposes of semi-monthly billings, our fees will be based on the hours charged at our hourly rates as set forth in the letter agreement. We review and revise our hourly billing rates effective January l of each year.



Contingent Success Fees. As described in the attached agreement.



Out-of-Pocket Expenses. In addition to hourly fees as defined in the letter agreement,
the Company shall pay directly or reimburse APS upon receipt of periodic billings for all reasonable out-of-pocket expenses incurred in connection with this assignment.



Retainer. We require a retainer to be applied against the time charges and expenses specific to the engagement. We will submit
semi-monthly invoices for services rendered and expenses incurred as described above, and will offset such invoices against the retainer. Payment will be due upon receipt of the invoices to replenish the retainer to the agreed-upon amount. Any
unearned portion of the retainer will be returned to you at the termination of the engagement.



Section 3. Relationship of the Parties.



The parties intend that an independent contractor relationship will be created by this Agreement. As an independent contractor, APS will have complete and exclusive charge of the management and operation of its business, including hiring
and paying the wages and other compensation of all its employees and agents, and paying all bills, expenses and other charges incurred or payable with respect to the operation of its business. Of course, as an independent contractor, neither the
Temporary Staff nor APS will be entitled to receive from the Company any vacation pay, sick leave, retirement, pension, or social security benefits, workers compensation, disability, unemployment insurance benefits, or any other employee
benefits. APS will be responsible for all employment, withholding, income and other taxes incurred in connection with the operation and conduct of its business. Temporary Staff will not be considered employees of the Company except for purposes of
this agreement.



The Company agrees to promptly notify APS if it extends (or
solicits the possible interest in receiving) an offer of employment to an employee of APS and agrees that it will pay APS a cash fee, upon hiring, equal to 150% of the aggregate first years annualized compensation, including any other
compensation, to be paid to any person working for the Company on behalf of APS that the Company or any of its subsidiaries or affiliates hires at any time up to two years subsequent to the date of the final invoice rendered by APS with respect to
this engagement. This agreement does not prohibit the Company from making general solicitations for employment or from soliciting for employment any individuals who have ceased to be employees or agents of APS prior to such solicitation.



Section 4. Confidentiality.



APS agrees to keep confidential all Information obtained from the Company, and neither APS
nor the Temporary Staff will disclose to any other person or entity, or use for any purpose other than specified herein, any information pertaining to the Company or any affiliate thereof, which is either non-public, confidential, or proprietary in
nature (Information) that it obtains or is given access to during the performance of the services provided hereunder. The foregoing is not intended to nor shall be construed as prohibiting APS or the Temporary Staff from disclosure
pursuant to a valid subpoena or court order, but neither APS nor such Temporary Staff shall encourage, suggest, invite or request, or assist in securing, any such subpoena or court order, and the Temporary Staff shall immediately give notice of any
such subpoena or court order by fax transmission to the Company. Furthermore, APS and the Temporary Staff may make reasonable disclosures of Information to third parties in connection with their performance of their obligations and assignments
hereunder. In addition, APS will have the right to disclose to others in the normal course of business its involvement with the Company.



Information includes data, plans, reports, schedules, drawings, accounts, records, calculations, specifications, flow sheets, computer programs, source or object codes,
results, models, or any work product relating to the business of the Company, its subsidiaries, distributors, affiliates, vendors, customers, employees, contractors and consultants.



The Company acknowledges that all information (written or oral) generated by the Temporary Staff in connection with their engagement is
intended solely for the benefit and use of the Company (limited to its management and its Board of Directors) in considering the transactions to which it relates. The Company agrees that no such information shall be used for any other purpose or
reproduced, disseminated, quoted or referred to with attribution to APS at any time in any manner or for any purpose other than accomplishing the tasks referred to herein, without APS prior approval (which shall not be unreasonably withheld)
except as required by law.



Section 5. Intellectual Property.



Except for those methodologies, processes techniques, ideas, concepts and
know-how developed independently by APS or supplied in connection with this agreement and prior to this agreement (collectively known as APS Work Product), Company shall retain all right, title, and interest in and to: (i) the work
product, including but not limited to, all patent, copyright, trademark, and other intellectual property rights therein; and (ii) all methodologies, processes, techniques, ideas, concepts, and know-how embodied in the work product, (together
the Work Product).



---

AP SERVICES, LLC

GENERAL TERMS AND CONDITIONS



APS hereby transfers and assigns to Company all right, title, and interest that APS may have in the Work Product and all intellectual property rights therein. Company
may, solely for its internal business purposes, use, copy, distribute internally, and modify the Work Product described under the letter agreement. The Company shall not, without APS prior written consent (which shall not be unreasonably
withheld), disclose to a third party, publicly quote, or make reference to the Work Product. Subject to the confidentiality restrictions contained in Section 4, APS may use the Work Product for any purpose.



Section 6. Framework of the Engagement.



The Company acknowledges that it is hiring the Temporary Staff purely to assist the Company
and its Board of Directors in the management and restructuring of the Company. This engagement shall not constitute an audit, review or compilation, or any other type of financial statement reporting or consulting engagement that is subject to the
rules of the AICPA, the SSCS, or other such state and national professional bodies.



Section 7. Indemnification



In bankruptcy engagements, neither
APS nor its employees not serving as officers of the Company will be entitled to indemnification provided by the Company. However, APS employees serving as officers of the Company will be entitled to the benefit of the most favorable indemnities
provided by the Company to its officers and directors, whether under the Companys by-laws, certificates of incorporation, by contract or otherwise. The Company agrees that it will use its best efforts to specifically include and cover APS
employees serving as officers of the Company under the Companys policy for directors and officers (D&O) insurance.



In non-bankruptcy engagements, it is our practice to receive indemnification. Accordingly, in consideration of our agreement to act on your behalf in connection with this
engagement, you agree to indemnify, hold harmless, and defend us (including our principals, employees, Temporary Staff and agents) from and against all claims, liabilities, losses, damages and reasonable expenses as they are incurred, including
reasonable legal fees and disbursements of counsel, and the costs of our professional time (our professional time will be reimbursed at our rates in effect when such future time is required), relating to or arising out of the engagement, including
any legal proceeding in which we may be required or agree to participate but in which we are not a party. We, our principals, employees, Temporary Staff and agents may, but are not required to, engage a single firm of separate counsel of our choice
in connection with any of the matters to which this indemnification agreement relates. This indemnification agreement does not apply to actions taken or omitted to be taken by us in bad faith.



In addition to the above indemnification, APS employees serving as officers of the Company
will be entitled to the benefit of the most favorable indemnities provided by the Company to its officers and directors, whether under the Companys by-laws, certificates of incorporation, by contract or otherwise. In the event that other APS
employees become officers of the Company, such individuals will be entitled to the same benefit.



The Company agrees that it will use its best efforts to specifically include and cover APS employees serving as officers of the Company under the Companys policy for directors and officers
(D&O) insurance. In the event that the Company is unable to include APS appointees under the Companys policy or does not have first dollar coverage as outlined in the preceding paragraph in effect for at least $10 million,
(e.g., such policy is not reserved based on actions that have been or are expected to be filed against officers and directors alleging prior acts that may give rise to a claim), it is agreed that APS will attempt to purchase a separate D&O
policy that will cover its employees and agents only and that the cost of same shall be invoiced to the Company as an out of pocket cash expense. If APS is unable to purchase such D&O insurance, then we reserve the right to terminate this
agreement. In the event that other Temporary Staff become officers of the Company, such individuals will be entitled to the same benefit. The obligations of the parties as reflected herein shall survive the termination of the engagement.



Section 8. Disclosures.



We know of no fact or situation, other than those disclosed in Schedule 3, which would
represent a conflict of interest for us with regard to the Company.



While we
are not aware of any relationships, other than those disclosed in Schedule 3, that connect us to any party in interest, because APS is a consulting firm that serves clients on a national basis in numerous cases, it is possible that APS may have
rendered services to or have business associations with other entities which had or have relationships with the Company. APS has not and will not represent the interests of any of these aforementioned entities in this case, involving the Company.



Section 9. Governing Law



This letter agreement is governed by and construed in accordance with the laws of the State
of Michigan with respect to contracts made and to be performed entirely therein and without regard to choice of law or principles thereof.



Any controversy or claim arising out of or relating to this contract, or the breach thereof, shall be settled by arbitration. Each party shall appoint one non-neutral
arbitrator. The two party arbitrators shall select a third arbitrator. However, if within thirty days after their appointment the two party arbitrators do not select a third arbitrator, the third arbitrator shall be selected by the American
Arbitration Association (AAA). The arbitration shall be conducted under the AAAs Commercial Arbitration Rules, and the arbitrators shall issue a reasoned award. The arbitrators may award costs and attorneys fees to the prevailing party.
Judgment on the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. However, APS agrees that the arbitration provisions shall apply only to the extent that the Bankruptcy Court, or the U.S. District Court if
the reference is withdrawn, does not retain jurisdiction over a controversy or claim.



Section 10. Termination and Survival.



This Agreement to
provide Temporary Staff hereunder may be terminated at any time by written notice by one party to the other; provided, however, that notwithstanding such termination APS will be entitled to any fees and expenses due under the provisions of the
agreement, including Contingent Success Fee and Break Fee in accordance with Schedule 2. The Break Fee is due and payable at the Termination Date. Such payment obligation shall inure to the benefit of any successor or assignee of APS.



Additionally, unless APS is terminated by the Company for Cause (as defined below) or due to
circumstances described in the Contingent Success Fee provision in the Agreement, APS shall remain entitled to the Contingent Success Fee(s) that otherwise would be payable for the greater of 12 months from the date of termination or the period of
time that that has elapsed from the date of this letter to the date of termination. Cause shall mean:



(a) an APS representative acting on behalf of the Company is convicted of a felony, or

AP SERVICES, LLC

GENERAL TERMS AND CONDITIONS



(b) it is determined in good faith by the Board of Directors of the Company, and after thirty (30) days notice and opportunity to cure, either (i) an APS representative
engages in misconduct injurious to the Company, or (ii) an APS representative breaches any of his or its material obligations under this Agreement; or (iii) an APS representative willfully disobeys a lawful direction of the Board of Directors or
senior management of the Company.



Sections 2, 4, 5, 7, 9, 10, and 11 shall
survive the expiration or termination of the Agreement.



Section 11.
General.



Severability. If any portion of the letter agreement
shall be determined to be invalid or unenforceable, we each agree that the remainder shall be valid and enforceable to the maximum extent possible.



Entire Agreement. The Terms and the attached letter agreement contain the entire understanding of the parties relating to the services to be rendered by APS and
may not be amended or modified in any respect except in writing signed by the parties. APS will not be responsible for performing any services not specifically described in this letter or in a subsequent writing signed by the parties. If there is a
conflict between these Terms and the letter agreement, these Terms shall govern.



Notices. All notices required or permitted to be delivered under this letter agreement shall be sent, if to APS, to the address set forth in the letter agreement, to the attention of Mr. Melvin R. Christiansen, and if to Company, to
the address set forth in the letter agreement, to the attention of your General Counsel, or to such other name or address as may be given in writing to the other party. All notices under the letter agreement shall be sufficient if delivered by
facsimile or overnight mail. Any notice shall be deemed to be given only upon actual receipt.
