ARTICLE II

PURCHASE AND SALE OF INTERESTS

 

2.1 Purchase and Sale. Subject to the terms and conditions contained in this
Agreement, at the Closing, each Seller shall sell, assign, transfer, and deliver
to Buyer (or at

 

5

--------------------------------------------------------------------------------

Buyer’s discretion, Buyer and one or more of Buyer’s affiliates), and Buyer (or
Buyer and one or more of Buyer’s affiliates, as the case may be) shall accept
and purchase from each Seller, all of such Seller’s right, title, and interest
in and to (a) the Partnership Interests, (b) the MLO-Ohio Membership Interests,
and (c) the MEL Membership Interests (collectively, the “Interests”), free and
clear of any Encumbrances.

 

2.2 Total Consideration. In consideration for the Interests, Buyer (or Buyer and
one or more of Buyer’s affiliates, as the case may be) shall pay to Sellers the
following aggregate purchase price (the “Purchase Price”):

 

(a) Fifty-Three Million Dollars ($53,000,000) payable in cash at Closing (the
“Cash Purchase Price”) by wire transfer of immediately available funds to
Sellers in accordance with Schedule 2.2(a), and

 

(b) The contingent payments calculated in accordance with Section 2.3 of this
Agreement (collectively, the “Contingent Payments”).

 

2.3 Contingent Payments

 

(a) Tonnage Payment. For each of the twelve years immediately following the
Closing Date, if the aggregate tonnage of shipments from the Operations for such
year exceeds 12,500,000 net tons (“Tonnage Target”), Buyer shall pay to Sellers
an amount equal to Two Million One Hundred Thousand Dollars ($2,100,000)
(“Tonnage Payment”); provided that Tonnage Payments shall be made for no more
than ten of the twelve years immediately following the Closing Date so that the
maximum aggregate amount of the Tonnage Payments shall not exceed Twenty-One
Million Dollars ($21,000,000). In the event of a Force Majeure, the time period
used to determine whether one or more Tonnage Targets have been met and the
years in which Sellers are eligible to receive a Tonnage Payment shall be
extended in a manner reasonably agreed to by the Parties including consideration
of the seasonality of the business of the Operations. Exhibit 2.3(a) sets forth
an example of this Section 2.3(a).

 

(b) EBITDA Payment. For each of the ten years immediately following the Closing
Date, if during such year (i) Buyer is required by Section 2.3(a) to make a
Tonnage Payment, and (ii) the annual EBITDA target amounts described in Schedule
2.3(b) are exceeded in the aggregate by the MLO Quarries, the Operations, or
both, Buyer shall pay to Sellers the amounts reflected on Schedule 2.3(b) set
forth opposite the relevant EBITDA target amounts. The aggregate annual amount
payable by Buyer pursuant to this Section 2.3(b) shall not exceed One Million
Nine Hundred Thousand Dollars ($1,900,000). Exhibit 2.3(b) sets forth examples
of this Section 2.3(b).

 

(c) EBITDA Target Amounts and Capital Expenditure Amounts. The EBITDA target
amounts and Capital Expenditure amounts for each of the ten years immediately
following the Closing shall be as shown on Schedule 2.3(b). If, pursuant to a
written agreement among Buyer and Sellers, the Capital Expenditures exceed the
amount shown for such year on Schedule 2.3(b), the EBITDA target amounts shall
be adjusted upward by the amount of any EBITDA benefits specified in the written
agreement increasing the amount of Capital Expenditures. Exhibit 2.3(c) sets
forth an example of this Section 2.3(c).

 

6

--------------------------------------------------------------------------------

(d) Maximum Amounts. The maximum aggregate amount of the Contingent Payments to
be made by Buyer to Sellers shall be Forty Million Dollars ($40,000,000), and
the maximum annual Contingent Payments to be made by Buyer to Sellers shall be
Four Million Dollars ($4,000,000). Sellers acknowledge that no portion of the
Contingent Payments shall be guaranteed and that the Contingent Payments shall
be made only to the extent provided for in this Section 2.3.

 

(e) Contingent Payment. Except as provided in Section 2.3(a) with respect to
Force Majeure and subject to the provisions of that certain side letter
agreement between the parties executed and delivered on the Closing Date (the
“Side Letter”), the measurement periods for the Contingent Payments shall be
based upon the fiscal year of Buyer (January 1 through December 31), beginning
with January 1, 2000 of Buyer’s fiscal year 2000. The Buyer shall make annual
Contingent Payments as required by Section 2.3(a) and (b) to Sellers within
sixty (60) days of the end of the fiscal year of Buyer by wire transfer of
immediately available funds.

 

(f) Buyout. Promptly after the third anniversary of the Closing Date, the
Parties agree to meet to discuss in good faith, without any binding obligation
to reach an agreement, the terms of a buyout by Buyer of Sellers’ rights to any
future Contingent Payments.

 

(g) Change in Control; Sale of Assets

 

(i) If during the twelve-year period immediately following the Closing Date (the
“Tonnage Payment Period”), there is a Change in Control, then Buyer shall (1)
within three (3) business days of such Change in Control provide Sellers with
written notice of such Change in Control and (2) at the written election of
Sellers, pay to Sellers the Accelerated Payment within thirty (30) days of
Buyer’s receipt of written notice of Sellers’ election to accept the Accelerated
Payment. The term “Accelerated Payment” shall mean an amount equal to the sum of
the present values of annual payments of Two Million One Hundred Thousand
Dollars ($2,100,000) for each year remaining during the Tonnage Payment Period
(but in no event shall the number of years for which Tonnage Payments are made
or attributable exceed ten) as if such payments were made in consecutive years
starting with the next date on which a Tonnage Payment would otherwise come due
and calculated using a discount rate equal to the applicable interest rate at
the most recent auction of federal ten year treasury notes prior to the date the
Accelerated Payment is due and payable.

 

(ii) If, during the Tonnage Payment Period, (1) Buyer sells all or substantially
all of the assets or equity interests relating to the Operations, or (2) Buyer
makes a Fundamental Change, in Sellers’ reasonable judgment, in the business of
the Operations other than a Fundamental Change implemented with the written
concurrence of Michael D. Lundin or Sellers’ Representative (provided that
Sellers’ Representative is knowledgeable regarding the quarrying, processing,
and selling of limestone and is not, directly or indirectly, affiliated with a
competitor of Buyer or the Operations, and provided further that Peter Johnson,
Jim Rhude, Kent Rhude, and Robert Ross, Sr. shall

 

7

--------------------------------------------------------------------------------

each be deemed by Buyer to have the requisite degree of knowledge to serve as a
Sellers’ Representative) or a change resulting from a Force Majeure, Buyer shall
(A) within three (3) business days of the occurrence of such change provide
written notice of such change to Sellers, and (B) at the written election of
Sellers, shall pay to Sellers an amount equal to the Accelerated Payment
multiplied by (X) in the case of an asset or equity interest sale, the
percentage set forth on Schedule 2.3(g) and, (Y) in the case of a fundamental
change in the Operations as described above, 100%, within thirty (30) days of
Buyer’s receipt of written notice of Sellers’ election to accept such amount. If
an asset or equity interest sale as described in subsection 2.3(g)(ii)(X) occurs
for which less than 100% of the Accelerated Payment is paid, then (1) the
Tonnage Target shall be reduced by the percentage set forth in Schedule 2.3(g)
times the Tonnage Target previously in effect and (2) the annual EBITDA target
amounts described in Schedule 2.3(b) shall be reduced to amounts equal to 100%
minus the percentage set forth on Schedule 2.3(g) times the applicable annual
EBITDA target amounts set forth on Schedule 2.3(b).

 

(iii) If an Event of Default occurs during the Tonnage Payment Period, then
Buyer shall (1) within three (3) business days of the occurrence of such Event
of Default provide Sellers with written notice of such Event of Default, and (2)
at the written election of Sellers, pay to Sellers within thirty (30) days the
Accelerated Payment.

 

(iv) Acceptance by Sellers of the full amount of the Accelerated Payment shall
terminate immediately all of Buyer’s obligations to pay Tonnage Payments in
accordance with Section 2.3(b). Acceptance by Sellers of any payment offered by
Buyer in an amount less than the amount then due shall be deemed an acceptance
on account only, and Sellers’ acceptance of any such partial payment shall not
constitute a waiver of Sellers’ right to receive the entire amount due. Upon the
occurrence of an event with respect to which Sellers may demand an Accelerated
Payment pursuant to subsection 2.3(g)(i), (ii), or (iii) (an “Acceleration
Event”), neither the failure of Sellers to promptly exercise their right to
declare the Accelerated Payment to be immediately due and payable, nor the
failure of Sellers to demand strict performance of any other obligation of Buyer
(or any successor) set forth in Section 2.3 or 2.4, shall constitute a waiver of
any such rights, nor a waiver of such rights in connection with any future
Acceleration Event. The election by Sellers not to demand the Accelerated
Payment upon the occurrence of an Acceleration Event shall not waive the right
of Sellers to demand the Accelerated Payment upon the occurrence of any
subsequent Acceleration Event. The election by Sellers to demand the Accelerated
Payment with respect to an asset or equity interest sale as described in
subsection 2.3(g)(ii)(X) for which less than 100% of the Accelerated Payment is
paid shall not preclude Sellers from demanding any remaining amount of such
Accelerated Payment upon the occurrence of a subsequent Acceleration Event.

 

(v) Notwithstanding any provision herein to the contrary, upon the occurrence of
an Acceleration Event, Sellers must elect in writing to have Buyer pay the
Accelerated Payment within thirty (30) days of delivery of written notice of the
occurrence of the Acceleration Event from Buyer. If Sellers fail to make such
election within such thirty (30) day period, then Sellers shall have waived
their right to the Accelerated Payment for such Acceleration Event.

2.4 Procedures relating to Contingent Payments

 

(a) Tonnage Statement. Within thirty (30) days following the completion of each
of the twelve years referred to in Section 2.3(a) (or until the maximum amount

showing the tonnage of shipments from the Operations for such year (the
“Preliminary Tonnage Statement”). Following receipt of the Preliminary Tonnage
Statement, Sellers shall be afforded a period of thirty (30) days to review the
Preliminary Tonnage Statement (the “Tonnage Review Period”). To assist in any
such review, Buyer shall make available to Sellers within five (5) business days

of the Operations is denied or delayed by Buyer. At or before the end of the
Tonnage Review Period, Sellers shall either (i) accept the Preliminary Tonnage
Statement in its entirety or (ii) deliver to Buyer a written notice setting
forth a detailed explanation of those items in the Preliminary Tonnage Statement
that Sellers dispute (a “Notice of Tonnage Dispute”). If Sellers do not deliver

shall be deemed to have accepted the Preliminary Tonnage Statement in its
entirety.

 

(b) EBITDA Statement. Within thirty (30) days following the completion of each
of the ten years referred to in Section 2.3(b), Buyer shall prepare and deliver
to Sellers a statement showing the annual EBITDA of each MLO Quarry and the

Preliminary EBITDA Statement, Sellers shall be afforded a period of sixty (60)
days to review the Preliminary EBITDA Statement (the “EBITDA Review Period”). To
assist in any such review, Buyer shall make available to Sellers within five (5)
days of Sellers so requesting, and to any independent accounting firm selected
by Sellers (subject to such firm’s prior execution of Buyer’s standard
confidentiality agreement attached hereto as Exhibit 2.4(a)(1) and Buyer’s
independent accounting firm’s standard release attached hereto as Exhibit
2.4(a)(2)), whose fees and expenses shall be borne by Sellers, full access to
the books and records of the Operations, Buyer’s accountants work papers, and
such other records as reasonably requested by Sellers. The EBIDTA Review Period
shall be extended by one day for each day that access to the books and records
of the Operations is denied or delayed by Buyer. At or before the end of the
EBITDA Review Period, Sellers shall either (i) accept the Preliminary EBITDA
Statement in its entirety or (ii) deliver to Buyer a written notice setting
forth a detailed explanation of those items in the Preliminary EBITDA Statement
that Sellers dispute (a “ Notice of EBITDA Dispute”). If Sellers do not deliver
a Notice of EBITDA Dispute to Buyer within the EBITDA Review Period, Sellers
shall be deemed to have accepted the Preliminary EBITDA Statement in its
entirety.

--------------------------------------------------------------------------------

(c) Resolution of Disputes. Within a period of thirty days after delivery of a
Notice of Tonnage Dispute or a Notice of EBITDA Dispute, Buyer and Sellers shall
attempt to resolve in good faith any disputed items. If they are unable to do
so, any disputed items will be submitted to a mutually agreeable nationally
recognized firm of independent accountants for resolution (the “ Independent
Public Accountants”). Sellers and Buyer will share equally the cost of the
Independent Public Accountants. The determination of the disputed items by the
Independent Public Accountants will be final and binding on the parties and a
judgment on the determination of the Independent Public Accountant may be
entered by a court of competent jurisdiction. Any other disputes, including
those involving a Fundamental Change, shall be resolved in accordance with
Section 11.7 hereof.

 

2.5 Closing. Unless this Agreement shall have been terminated and the
transactions herein contemplated shall have been abandoned pursuant to Article
IX, and subject to the satisfaction or waiver of the conditions set forth in
Articles VII and VIII, the consummation of the transactions described in
Sections 2.1 and 2.2 of this Agreement (the “Closing”) shall take place at 10:00

Sellers any Interests unless, on the Closing Date, Sellers are able to sell to
Buyer one hundred percent (100%) of the Interests.

(a) Buyer and Sellers shall mutually agree to allocate the Purchase Price as set
forth on Schedule 2.7(a) to this Agreement (the “Allocation”). The parties
acknowledge that the Allocation has been determined pursuant to arm’s length
bargaining between the parties regarding the fair market values of the Company’s
assets in accordance with Section 1060 of the Internal Revenue Code of 1986, as
amended (the “Code”). The parties shall report (including with respect to the
filing of Form 8594 to the Internal Revenue Service) the sale and purchase for
all income tax purposes in a manner consistent with such allocation and will
not, in connection with the filing of such return, make any allocation of the
Purchase Price which is contrary to the Allocation. The parties agree to consult
with one another with respect to any tax audit, controversy or litigation
relating to the Allocation.

Requirements” means any law, statute, rule, ordinance, decree, regulation,
requirement, order (including any executive order) or judgment of any court or

transaction within the meaning of ERISA Section 406 (for which no exception or
exemption exists) has occurred with respect to any Plan.

 

(h) Neither the Company, any ERISA Affiliate, any of the Plans or any trust
created thereunder nor any trustee or administrator thereof has engaged in any
transaction or has taken or failed to take any action in connection with which
the Company, any ERISA Affiliate, any of the Plans, any such trust, any trustee
or administrator thereof, or any party dealing with the Plans or any such trust
could be subject to any liability, fine, penalty, tax or related charge under

shall apply, and (ii) except as set forth in Schedule 3.15, all contributions
required to be made by the Company to such multiemployer plan have been made or
are accrued and fully reflected in the Company Financial Statements.

litigation or arbitration concerning or involving any of the Plans. No

threatened or expected, with respect to any of the Plans. No claims have been
made, or are expected, with respect to any bond or any fiduciary or other
similar insurance with regard to the actions of any person in connection with
any of the Plans, nor has there been, nor is there expected, any notice to any
insurer under any such bond or policy with regard to any of such Plans. No
application for any bond or fiduciary liability or similar insurance policy has
been issued subject to any qualification, condition or exclusion.

contemplated by this Agreement will not (i) entitle any current or former

circumstances, which would reasonably be expected to result in such liability,
with respect to the business, assets, or properties of the Port Inland Quarry
except for any such non-compliance or liabilities which would not have a

(b) Except for any non-compliance which would not have a Material Adverse

“Buyer Companies”) are in compliance with any and all Environmental Laws
including, without limitation, (a) all Environmental Laws in all jurisdictions

similar organizations representing any of the Port Inland Quarry’s employees,
and (b) during the past two years, at the Port Inland Quarry, there has been no
request for collective bargaining or for an employee election from any employee,

in writing to Sellers. The

 

26

--------------------------------------------------------------------------------

last year for which the Internal Revenue Service audited the federal income tax
returns for Buyer was 1994. There are no agreements or applications by Buyer for
an extension of time for the assessment or payment of any Taxes nor any waiver
of the statute of limitations in respect of Taxes. There are no Tax liens on any
of the assets of Buyer, except for liens for Taxes not yet due or payable. There
are no requests for rulings or determinations in respect of any Tax pending
between Buyer and any Taxing Authority. To the Knowledge of Buyer, no written
claim has been received by Buyer from any Taxing Authority in a jurisdiction in
which Buyer does not file Tax Returns that it is or may be subject to taxation
by that jurisdiction.

 

(c) At all times on or after January 1, 1994, Buyer has not and has never been a
party to or bound by any tax indemnity agreement, tax sharing agreement, tax
allocation agreement or similar agreement or arrangement.

 

(d) Except for amounts not to exceed $750,000 in the aggregate, Buyer has

to have been withheld and paid over in connection with amounts paid or owing to
any employee, creditor, independent contractor, or other third party.

 

(e) There are no accounting method changes or proposed accounting method changes
for Buyer, nor any other item, that could give rise to an adjustment under

be required to make any Section 481 adjustments as a result of the transaction
contemplated by this Agreement.

 

4.19 Compliance with Laws. Buyer’s operation of the Port Inland Quarry complies
in all material respects with all Laws. With respect to the Port Inland Quarry,
Buyer has not received a written notice of violation from any governmental
authority.

 

4.20 Employee Benefit Plans. Buyer has made full payment of all amounts
required, under applicable law or under the governing documents, to have been
paid as a contribution to or a benefit under each “employee benefit plan”
(within the meaning of ERISA Section 3(3)) that Buyer sponsors, maintains,
contributes to, has liability with respect to, or has an obligation to
contribute to such plan (the “Buyer Plans”). The liability of Buyer with respect
to each Buyer Plan has been fully funded based upon reasonable and proper
actuarial assumptions, has been fully insured, or has been fully reserved for on
its financial statements. No changes have occurred or are expected to occur that
would cause a material increase in the cost of providing benefits under the
Buyer Plans. With respect to each Buyer Plan that is intended to be qualified
under Code Section 401(a): (a) the Buyer Plan and any associated trust
operationally comply with the applicable requirements of Code Section 401(a),
(b) the Buyer Plan and any associated trust have been amended to comply with all
such requirements as currently in effect, other than those requirements for
which a retroactive amendment can be made within the “remedial amendment period”
available under Code Section 401(b) (as extended under Treasury Regulations and
other Treasury pronouncements upon which taxpayers may rely), (c) the Buyer Plan
and any associated trust have received a favorable determination letter from the
Internal Revenue Service stating that the Buyer Plan qualifies under Code
Section 401(a), that the associated trust qualifies under Code Section 501(a)
and, if applicable, that any cash or deferred arrangement under the Buyer Plan
qualifies under Code Section 401(k), (d) the Buyer Plan

 

27

--------------------------------------------------------------------------------

currently satisfies the requirements of Code Section 410(b), and (e) no
contribution made to the Buyer Plan is subject to an excise tax under Code
Section 4972. With respect to any pension plan (within the meaning of ERISA
Section 3(2)), the “accumulated benefit obligation “ of Buyer with respect to
the pension plan (as determined in accordance with Statement of Accounting
Standards No. 87, “Employers’ Accounting for Pensions”) does not exceed the fair
market value of pension plan assets, or if it does, it does not have a material
adverse effect on Buyer taken as whole. Buyer has not had a complete or partial
withdrawal from any multiemployer plan (any pension plan that is subject to the
requirements of Subtitle E of Title IV of ERISA) which has resulted in material
liability to Buyer which has not been satisfied, and Buyer would not become
subject to any material liability under ERISA if Buyer were to withdraw
completely from all such multiemployer plans to which Buyer contributes or has
an obligation to contribute.

 

4.21 Company Information. The documents referred to in Schedule 4.21 of this
Agreement (the “Buyer’s SEC Documents”) constitute all of the documents (other
than preliminary material, pre-effective registration statements or registration
statements relating to employee stock option or compensation plans) that the
Company was required to file with the Securities and Exchange Commission (the
“SEC”) since December 31, 1999. Each of the Buyer’s SEC Documents has been duly
filed, and when filed complied in all material respects with the requirements of
the applicable form, statutes, rules and regulations of the SEC. Each of the
Buyer’s SEC Documents, as amended by any amendments duly filed with the SEC and
referred to in Schedule 4.21, was complete and correct in all material respects
as of the date filed and did not contain any untrue statement of material fact
or omit to state a material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances in
which made, not misleading. Since December 31, 1999, there has not been any
material adverse change in the condition (financial or otherwise) or results of
operation of Buyer and its Subsidiaries. The audited financial statements of
Buyer included in the Buyer’s SEC Documents have been prepared in accordance
with GAAP applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto) and fairly present the consolidated
financial position of Buyer and its subsidiaries as at the date thereof and the
consolidated results of their operations and cash flow for the periods then
ended. The unaudited financial statements included in any Buyer’s SEC Documents
comply as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto; and such unaudited financial statements are fairly presented in
conformity with GAAP (except as permitted by Form 10-QSB of the SEC) applied on
a basis substantially consistent with that of the audited financial statements
included in the Buyer’s SEC Documents, subject to year-end audit adjustments.

effectively title in the Interests in Buyer, and to fulfill their obligations
under this Agreement all at the sole cost and expense of the requesting Party.

 

6.7 Public Announcements. No party hereto shall make any public announcement or

responsible for the SBT required to be paid in connection with such SBT Return.
Any refund of SBT due to the Company with respect to a period ending on or

deliver an executed certificate to Buyer, as described in Treasury Regulation

either of them reasonably may request of the other in filing any Tax Return,

relevant Tax Returns or portions thereof, together with accompanying schedules
and related work papers and documents relating to rulings or other

The parties further agree, upon request, to use all reasonable efforts to obtain
any certificate or other document from any governmental authority, Taxing
Authority, or customer of MLO, MLO-Ohio and MEL or Buyer or any other person as
may be necessary to mitigate, reduce or eliminate any Tax that could be imposed
(including but not limited to with respect to the transactions contemplated by
this Agreement).

indemnification therefor under Section 10).

 

6.14 Formation of Limited Liability Company. Prior to the Closing Date, a single
member Delaware limited liability company (“New LLC”) shall be formed whose sole
member is MLO and Sellers shall cause MLO to transfer and convey to New LLC the
assets of MLO identified on Schedule 6.14.

 

6.15 Sellers’ Representative. Pursuant to the Sellers’ Representative Agreement,
the Sellers have appointed the Sellers’ Representative to act as each such
Seller’s representative, attorney-in-fact and agent, with full power and
authority to do all of the following:

 

(a) execute and deliver and receive, on behalf of each Seller, all amendments,

Agreement or in connection with the transactions contemplated by this Agreement;

 

(b) receive any amount delivered by Buyer to such Seller pursuant to this

made by Buyer to Sellers hereunder to Sellers’ Representative. If Sellers’
Representative (or his successor or assign) shall resign, become incapacitated,
die or otherwise cease to perform the duties as the Sellers’ Representative, his
successor (chosen pursuant to the terms of the Sellers’ Representative
Agreement) shall become the Sellers’ Representative and shall provide written

and interest evidenced by those notes identified on Schedule 6.17(b) (the

Notes from the Bank, MLO (or Buyer if received by Buyer) shall cancel the
Shareholder Notes and deliver them to Michael Lundin and Kent Rhude.

 

(c) To facilitate the transactions described in Section 6.17(a) and (b),
pursuant to letters of direction from Michael Lundin, Kent Rhude and MLO, Buyer
may wire transfer directly to the Bank a portion of the Cash Purchase Price
equal to the amount of the Shareholder Indebtedness and receive a credit against
the Cash Purchase Price equal to such amount.

 

6.18 Employee Benefits Matters.

 

(a) As soon as practicable after the Closing Date, but in no event more than
ninety (90) days after such date, Sellers shall cause Sellers’ Advisors (such
term to include attorneys, accountants, actuaries and other professionals
selected by Sellers) to prepare and make a filing with the Internal Revenue
Service (“IRS”) pursuant to the EPCRS program, to review those matters relating
to the Michigan Limestone Operations Limited Partnership 401(k) Plan For
Salaried Employees which are disclosed on Schedule 3.15 which may affect the
qualified status of such plan. Sellers shall be solely and absolutely
responsible for payment of all filing fees, expenses and penalties associated
with Sellers’ Advisors preparing, making and responding to the IRS in connection
with such EPCRS filing and implementing all remedial actions requested by the
IRS. In addition, but not by way of limitation, Sellers shall reimburse Buyer
for the full amount which Buyer is required to contribute to such plan or
otherwise pay in connection with such EPCRS filing in order to finalize such
filing and receive approval from the IRS of the correction methodology proposed
by Sellers in this regard.

 

(b) As soon as practicable after the Closing Date but in no event more than
ninety (90) days after such date, Sellers shall cause Sellers’ Advisors to
prepare and make a filing with the IRS pursuant to the EPCRS program, to review
those matters relating to the Michigan Limestone Operations Limited Partnership
Pension Plan For Salaried Employees which are disclosed on Schedule 3.15 which
may affect the qualified status of such plan. Sellers shall be solely and
absolutely responsible for payment of all filing fees, expenses and penalties
associated with Sellers’ Advisors preparing, making and responding to the IRS in
connection with such EPCRS filing and implementing all remedial actions
requested by the IRS. In addition, but not by way of limitation, upon
finalization of such EPCRS filing and receipt of approval from the IRS of the
correction methodology required in this regard, Sellers shall promptly pay Buyer
that amount as determined by Sellers’ actuaries, equal to the excess (if any) of
the present value of all accrued benefits under such plan (as modified in
connection with such EPCRS filing) as of the Resolution Date, over the market
value of the plan’s assets as of such date. For purposes of this Section
6.18(b), “Resolution Date” shall mean the date a definitive written agreement is
entered into between Buyer or one of its Affiliates and the IRS resolving
matters described in this Section 6.18(b).

 

35

--------------------------------------------------------------------------------

(c) Buyer agrees to cooperate with Sellers to execute such documents (including,
but not limited to, powers of attorney naming Sellers’ Advisors) and take any
and all such actions as Sellers reasonably determine are necessary or advisable
to facilitate resolution of the EPCRS filings described above. Sellers agree to
consult with Buyer regarding such EPCRS filings and keep Buyer apprised of the
status of such filings, but Sellers shall retain sole authority and discretion
with regard to such filings. Sellers agree that prior to taking any action
associated with the EPCRS program, Sellers will provide notice to Buyer of such
action and provide Buyer with a reasonable opportunity to review and comment on
any such action, and Sellers agree to consider any such comments in good faith
with respect to such action. Sellers shall retain sole authority and discretion
with regard to (i) the identity of Sellers’ Advisors (whose engagement shall be
subject to Buyer’s prior approval, which shall not be unreasonably withheld)
that will assist Sellers in connection with such filings and in negotiations
with the IRS; (ii) the assumptions (including actuarial assumptions) to be
utilized by such Sellers’ Advisors in preparing, making and responding to the
IRS in connection with such filings; and (iii) the specific methods of any and
all corrections to be proposed, negotiated and finalized with the IRS with
respect to such filings. Notwithstanding the foregoing, Buyer agrees that Dykema
Gossett PLLC, Calfee, Halter & Griswold LLP and Investmart, Inc. are acceptable
to Buyer as Sellers’ Advisors, and Seller agrees that the discount rate to be
used for purposes of (ii) above shall be eight percent (8%).

 

(d) For all purposes of this section 6.18, any action required to be taken by
Seller shall be taken by Sellers’ Representative on behalf of Seller.

ARTICLE IX

TERMINATION

 

9.1 Termination. This Agreement may be terminated at any time prior to the
Closing Date:

 

(a) by the mutual written consent of Buyer and Sellers;

 

(b) by either Buyer or Sellers:

 

(i) if any court or governmental or regulatory agency, authority, or body of
competent jurisdiction shall have enacted, promulgated, or issued any statute,
rule, regulation, ruling, writ, or injunction, or taken any other action,
restraining, enjoining, or otherwise prohibiting the transactions contemplated
hereby and all appeals and means of appeal therefrom have been exhausted; or

 

(ii) if the Closing shall not have occurred on or before December 11, 2000;
provided, however, that the right to terminate this Agreement pursuant to this
Section 9.1(b)(ii) shall not be available to any party whose breach of any
representation or warranty or failure to perform or comply with any obligation
under this Agreement has been the cause of, or resulted in, the failure of the
Closing to occur on or before such date;

 

(c) by Buyer:

 

(i) if Buyer does not have sufficient funds to pay the Cash Purchase Price at
the Closing as a result of one or more of its lenders refusing to provide
funding as the result of adverse conditions affecting the financial markets
generally;

 

(ii) if any of the conditions specified in Article VII have not been met or
waived prior to such time as such condition can no longer be satisfied; or

 

(iii) if there has been a material misrepresentation by any Seller or MLO or a
breach by any Seller or MLO of any of their representations, warranties,
covenants, or other obligations hereunder, such breach results in a Material
Adverse Effect, and such breach shall not have been cured within ten (10) days
after written notice thereof has been delivered by Buyer to Sellers; or

 

(d) by Sellers:

 

(i) if any of the conditions specified in Article VIII shall not have been met

39

--------------------------------------------------------------------------------

(ii) if there has been a material misrepresentation by Buyer or a breach by
Buyer of any of its representations, warranties, covenants, or other obligations
hereunder, such breach results in a Material Adverse Effect, and such breach
shall not have been cured within ten (10) days after written notice thereof has

except that nothing herein shall relieve any party from liability for a breach

ARTICLE X

INDEMNIFICATION

 

10.1 Indemnification by Sellers. Each Seller, severally and not jointly, hereby
agrees to defend, indemnify, and hold harmless Buyer, and shall reimburse Buyer
for, from and against each claim, loss, liability, cost, and expense (including
reasonable attorney’s fees), all such items to be net of any tax benefits and
insurance proceeds recovered or recoverable by Buyer (collectively, “Losses”),
to the extent resulting from or arising out of any breach of any representation
or warranty or covenant of such Seller contained in this Agreement or any
agreement, document, or instrument delivered in connection with or pursuant to
this Agreement.

 

10.2 Indemnification by Buyer. Buyer hereby agrees to defend, indemnify, and
hold harmless Sellers and shall reimburse Sellers for, from and against all
Losses to the extent resulting from or arising out of any breach of any
representation or warranty or covenant of Buyer contained in this Agreement or
in any agreement, document, instrument delivered in connection with or pursuant
to this Agreement. The term “Losses” shall include a decrease in the amount of
any Contingent Payment that is directly attributable to Buyer’s material breach
of a representation or warranty of Buyer set forth in this Agreement.

 

10.3 Procedure.

 

(a) The indemnified party shall promptly notify in writing the indemnifying
party of any claim, demand, action, or proceeding for which indemnification will
be sought under Sections 10.1 or 10.2 of this Agreement, and, if such claim,
demand, action, or proceeding is a third party claim, demand, action, or
proceeding, the indemnifying party will have the right at its

 

40

--------------------------------------------------------------------------------

expense to assume the defense thereof using counsel reasonably acceptable to the
indemnified party; provided, however, in the case of any claim (an “Excess
Claim”) in which the indemnified party’s aggregate Losses could exceed the
indemnifying party’s aggregate liability pursuant to Section 10.3(b), the
indemnifying party will have the right, at its expense, to assume the defense
thereof only with the indemnified party’s written consent. The failure to
provide such prompt notice shall not affect the indemnification provided
hereunder except to the extent, if any, the indemnifying party shall have been
actually prejudiced as a result of such delay or failure. Should the
indemnifying party assume the defense of such a third party claim, demand,
action, or proceeding or should the indemnified party unreasonably withhold its
consent to the assumption by the indemnifying party of the defense of any Excess
Claim, the indemnifying party shall not be liable to the indemnified party for
legal expenses subsequently incurred by the indemnified party in connection with
the defense thereof. The indemnified party shall have the right to participate,
at its own expense, with respect to any such third party claim, demand, action,
or proceeding, it being understood that the indemnifying party shall control any
defense assumed by the indemnifying party. In connection with any such third
party claim, demand, action, or proceeding, Buyer and Seller shall cooperate
with each other and provide each other with reasonable access to and retain all
relevant books and records in their possession. No such third party claim,
demand, action, or proceeding shall be settled without the prior written consent
of the indemnified party. If a firm written offer is made to settle any such
third party claim, demand, action, or proceeding, which offer includes an
unconditional provision providing for the giving by the claimant to the
indemnified party of a release from all liability in respect of such claim,
demand, action, or proceeding and does not require any payment by the
indemnified party or impose any other obligations (such as an affirmative
action, negative covenant, or equitable relief) upon the indemnified party and
the indemnifying party proposes to accept such settlement and the indemnified
party refuses to consent to such settlement, then: (i) the indemnifying party
shall be excused from, and the indemnified party shall be solely responsible
for, all further defense of such third party claim, demand, action or
proceeding; and (ii) the maximum liability of the indemnifying party relating to
such third party claim, demand, action or proceeding shall be the amount of the
proposed settlement if the amount thereafter recovered from the indemnified
party on such third party claim, demand, action or proceeding is greater than
the amount of the proposed settlement. Whether or not the indemnifying party
shall have assumed the defense of any such third party claim, action, demand or
proceeding, no indemnified party shall admit any liability with respect to, or
settle, compromise or discharge any such claim, demand, action or proceeding
without the indemnifying party’s prior written consent, which shall not be
unreasonably withheld.

 

(b) Buyer and Sellers shall cooperate with each other with respect to resolving
any claim or liability with respect to which one party is obligated to indemnify
any other Person hereunder, including by making commercially reasonable efforts
to mitigate or resolve any such claim or liability. In the event that Buyer or
Sellers shall fail to make such commercially reasonable efforts to mitigate or
resolve any claim or liability, then notwithstanding anything else to the
contrary herein, the other party shall not be required to indemnify any Person
for any Losses that could reasonably be expected to have been avoided if Buyer
or Sellers, as the case may be, had made such efforts.

 

41

--------------------------------------------------------------------------------

10.4 Maximum Liability; Deductible.

 

(a) Notwithstanding any provision contained herein to the contrary (but subject
to Section 10.4(c) below), (i) Sellers shall have no liability under Section
10.1 unless the aggregate of all Losses to which Buyer shall be entitled to
indemnification pursuant to Section 10.1 hereof exceeds on a cumulative basis an
amount equal to $300,000 in which event such parties shall be liable for all
Losses in excess of such amount; (ii) in no event shall the aggregate liability
of Sellers under Section 10.1 exceed $21,000,000 (the “Cap”); provided that the
Cap shall be reduced each year during the Tonnage Payment Period by the amount
of any Tonnage Payments paid by Buyer pursuant to Subsection 2.3(a); and (iii)
in no event shall the aggregate liability of Sellers under Section 10.1 with
respect to all representations and warranties other than Section 3.16, exceed
$10,000,000 (the “Non-Environmental Cap”); provided that the Non-Environmental
Cap shall be reduced annually on a proportionate basis, i.e., by an amount equal
to 0.476 times the amount of any Tonnage Payment paid by Buyer pursuant to
Section 2.3(a). Notwithstanding the foregoing provisions on the reduction of the
Cap, upon the occurrence of (x) a Termination Event, or (y) an Acceleration
Event of the type described in Section 2.3(g)(ii)(1) (Buyer’s sale of all or
substantially all of the assets or equity interests relating to the Operations)
or 2.3(g)(iii) (the occurrence of an Event of Default), the Cap and the
Non-Environmental Cap shall both be reduced to zero dollars; provided, however,
that if Sellers are entitled to the Accelerated Payment pursuant to Section
2.3(g)(ii)(B) (Fundamental Change), then, (1) the Cap shall be reduced to the
amount of the Accelerated Payment and the Non-Environmental Cap to an amount
equal to 0.476 times the amount of the Accelerated Payment and (2) in each
subsequent year, the Cap shall be further reduced by an amount equal to the
Accelerated Payment divided by the number of years remaining at the time of the
Accelerated Payment comes due and owing in the Tonnage Payment Period (which
shall not be more than ten (10) minus the number of years in which Sellers had
previously received a Tonnage Payment) and the Non-Environmental Cap shall be
reduced by 0.476 times such amount. The limitations set forth in this Section
10.4(a) shall not apply to any breach of the representations and warranties set
forth in Sections 3.1, 3.4, 3.10 with respect to title to property, and 3.24 and
the covenants set forth in Section 6.8, 6.9, and 6.10.

 

(b) Sellers’ obligations to indemnify Buyer under this Article X with respect to
any breach of Sections 3.1, 3.4 and 3.10 with respect to title to property, and
3.24 and the covenants set forth in Sections 6.8, 6.9, and 6.10 shall be
satisfied first by an offset against the Tonnage Payments due during the Tonnage
Payment Period and thereafter from payments from Sellers. Except as set forth in
the preceding sentence, Sellers’ obligations to indemnify Buyer under this
Article X shall be satisfied solely by an offset against the Tonnage Payments,
and Buyer shall have no further recourse against Sellers. To the extent that the
Tonnage Payments in any one year are insufficient to satisfy the indemnification
obligations of Sellers under this Article X, Buyer may satisfy such
indemnification obligations by an offset against subsequent Tonnage Payments
coming due in later years during the Tonnage payment Period. Notwithstanding the
foregoing, if Buyer has paid the Accelerated Payment, Sellers’ obligations to
indemnify Buyer under this Article X shall be satisfied by payments from Sellers
but only to the extent of the existing Cap or the Non-Environmental Cap, as
applicable, as reduced pursuant to Section 10.4(a).

 

42

--------------------------------------------------------------------------------

(c) Neither the deductible referred to in Section 10.4(a)(i) nor the Cap shall
apply to Sellers obligations under Section 6.18 of this Agreement, it being
understood that Sellers obligations thereunder shall be absolute.

 

10.5 Survival.

 

(a) Subject to Section 10.5(b) below, all representations and warranties by the
parties contained in this Agreement or in any certificate delivered pursuant
hereto shall survive the Closing solely for purposes of Section 10.1 and 10.2
and shall terminate on the date which is eighteen (18) months after the Closing
Date.

 

(a) The representations and warranties contained in Section 3.16 of this
Agreement shall survive for a period of ten years, the representations and
warranties contained in Section 3.24 of this Agreement shall survive for the
full period of all applicable statutes of limitations, and the covenants in this
Agreement shall survive until fully performed.

 

10.6 Exclusive Remedy. The remedy provided for in this Article X is the
exclusive remedy of a Party for any claim that arises under this Article X;
provided that this Section 10.6 shall not prevent any party from seeking or
obtaining specific performance, injunctive relief or other equitable remedies.

 

10.7 Limitation. No Losses shall be asserted by a Party which arise out of any
breach or inaccuracy of any representation, warranty, or covenant made by the
other Party if the Party had actual knowledge of such breach or inaccuracy on
the Closing Date.

 

ARTICLE XI

MISCELLANEOUS PROVISIONS

 

11.1 Contents of Agreement. The Confidentiality Agreement, this Agreement,
together with the Schedules, the Side Letter, certificates, and other
instruments and documents delivered pursuant hereto, embodies the entire
understanding of the parties hereto with respect to the subject matter hereof,
and supersedes all prior agreements or understandings among the parties
regarding those matters.

 

11.2 Amendment, Waiver; Parties in Interest, Etc.

 

(a) This Agreement may be amended, modified, or supplemented only by a written
instrument duly executed by each of the parties hereto, which writing makes
express reference to this Section 11.2. If any provision of this Agreement shall
for any reason be held to be invalid, illegal, or unenforceable in any respect,
such invalidity, illegality, or unenforceability shall not affect any other
provision hereof, and this Agreement shall be construed as if such invalid,
illegal, or unenforceable provision had never been contained herein.

 

(b) Any term or provision of this Agreement may be waived at any time by the
party entitled to the benefit thereof by a written instrument duly executed by
such party. Any such waiver shall constitute a waiver only with respect to the
specific matter described in such writing

 

43

--------------------------------------------------------------------------------

and shall in no way impair the rights of the party granting such waiver in any
other respect or at any other time. Neither the waiver by either of the Parties
of a breach of or a default under any of the provisions of this Agreement, nor
the failure by any of the Parties, on one or more occasions, to enforce any of
the provisions of this Agreement or to exercise any right or privilege
hereunder, shall be construed as a waiver of any other breach or default of a
similar nature, or as a wavier of any of such provisions, rights or privileges
hereunder.

 

(c) This Agreement is being made and entered into solely for the benefit of
Buyer, Sellers, and MLO, and none of Buyer, Sellers, or MLO intends hereby to
create any rights in favor of any other Person, as a third party beneficiary of
this Agreement or otherwise. The Parties acknowledge and agree that nothing in
this Agreement creates an employment agreement between Buyer and Michael D.
Lundin or creates any obligation of Buyer to employ for any period of time, or
provide any benefits to, Michael D. Lundin.

 

11.3 Assignment.

 

(a) Buyer may assign any or all of its rights hereunder to any direct or
indirect wholly-owned subsidiary of Buyer (a “Permitted Subsidiary Transferee”),
and Buyer shall advise Sellers of any such assignment and shall designate such
party as the assignee and transferee. In the event of such assignment, the
Permitted Subsidiary Transferee may not assign any rights hereunder to any
Person not a direct or indirect wholly-owned subsidiary of Buyer. The transfer
of any ownership interest in a Permitted Subsidiary Transferee shall constitute
an assignment in violation of Section 11.3(a), and such assignment shall be
void. Any permitted assignment shall not be deemed to release Buyer from its
obligations hereunder and Buyer shall remain fully liable for performance of all
obligations under this Agreement.

 

(b) One or more of Sellers may distribute all of its rights under this Agreement
to its shareholders (the “Sellers’ Shareholders”). Any such distribution shall
not be deemed to release such Seller from its obligations hereunder, and such
Seller shall remain fully liable for performance of all obligations under this
Agreement. A Sellers’ Shareholder shall have discretion to transfer, by gift,
sale, or bequest (or other transfer effective upon death), all or any portion of
his or her rights under this Agreement to (i) his or her spouse, children,
grandchildren or parents or to any one or more of them (“Family Member”), (ii)
any entity, including but not limited to a corporation, limited liability
company, or partnership, a majority of whose ownership interests are owned by
Family Members, (iii) a grantor or testamentary trust of which a Seller’s
Shareholder is the settlor, or (iv) by making a charitable gift (that is
deductible for federal income or estate tax purposes) of all or any portion of
his or her rights under this Agreement.

 

(c) Subject to Section 11.3(a) and (b), neither Buyer nor Sellers may assign,
transfer, or otherwise dispose of directly or indirectly any of their rights
hereunder without the prior written consent of the other parties. Any attempted
assignment in violation of the foregoing shall be void.

 

(d) All the terms and provisions of this Agreement shall be binding upon, shall
inure to the benefit of, and shall be enforceable by the respective heirs,
successors, permitted assigns, and legal or personal representatives of the
parties hereto.

provisions concerning conflict of laws. Except as set forth below, each of the
parties hereto hereby irrevocably and unconditionally consents to submit to the
exclusive jurisdiction of the courts of the State of Delaware and of the United
State of America, in each case located in New Castle County, for any litigation
arising out of or relating to this Agreement and the transactions contemplated

contemplated hereby in the courts of the State of Delaware or the United States
of America, in each case located in New Castle County, and hereby further
irrevocably and unconditionally waives and agrees not to plead or claim in any
such court that any such litigation brought in any such court had been brought
in an inconvenient forum.

 

11.7 Dispute Resolution. If after the Closing any dispute arises under this
Agreement that is not settled promptly in the ordinary course of business, the
parties shall seek to resolve any such dispute between them, first, by
negotiating promptly with each other in good faith in face-to-face negotiations
in Toledo, Ohio. If the parties are unable to resolve the dispute between them
within twenty (20) business days (or such period as the parties shall otherwise
agree) through these face-to-face negotiations, any party may initiate mediation
of the controversy or claim in Toledo, Ohio in accordance with the procedures of
such mediation organization as the parties may agree. If the dispute has not
been resolved pursuant to such mediation procedure within thirty (30) business
days of the initiation of such procedure, or if the parties will not participate
in a mediation, any party shall be entitled to seek whatever legal or equitable
remedies that may be available to such party, subject to the terms of Sections
11.6 and 11.7 hereof. Notwithstanding the foregoing, the dispute resolution
procedure set forth in this Section 11.7 shall not apply to any dispute between
the parties hereto relating to or arising out of Seller’s Termination Fee or
Buyer’s Termination Fee, and in the event of such a dispute, either party shall
be entitled to seek whatever legal or equitable remedies that may be available
to it.
