ARTICLE 7 SURVIVAL OF REPRESENTATIONS AND WARRANTIES: INDEMNIFICATION Section 7.1 SURVIVAL. Except for the representations and warranties contained in Sections 3.1 and 3.3, which shall survive indefinitely, the representations and warranties of the parties hereto contained in this Agreement shall survive the Closing until twelve months after the Closing Date, and thereafter shall terminate and be of no further force or effect. Section 7.2 INDEMNIFICATION. (a) Concentra hereby indemnifies each Buyer and its affiliates, limited partners, general partners, directors, officers, trustees and employees against and agrees to hold each of them harmless from any and all damage, loss, liability and expense (including, without limitation, reasonable expenses of investigation and reasonable attorneys' fees and expenses in connection with any action, suit or proceeding) ("DAMAGES") incurred or suffered by any such party arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by Concentra pursuant to this Agreement; PROVIDED that with respect to any Buyer, (i) Concentra shall not be liable under this Section 7.2(a) unless the aggregate amount of Damages with respect to all matters referred to in this Section 7.2(a) for 19 which such Buyer has sought indemnification exceeds $100,000 and then only to the extent of such excess and (ii) the indemnifying parties' aggregate maximum liability under this Section 7.2(a) to any Buyer shall not exceed the amount of the Aggregate Purchase Price paid by such Buyer to Concentra. (b) Each Buyer hereby indemnifies, severally and not jointly, Concentra and its affiliates, limited partners, general partners, directors, officers and employees against and agrees to hold each of them harmless from any and all Damages incurred or suffered by any such party arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by such Buyer pursuant to this Agreement; PROVIDED that (i) such Buyer shall not be liable under this Section 7.2(b) unless the aggregate amount of Damages with respect to all matters referred to in this Section 7.2(b) exceeds $100,000 and then only to the extent of such excess and (ii) such Buyer's maximum liability under this Section 7.2(b) shall not exceed the amount of Aggregate Purchase Price paid by such Buyer to Concentra. (c) Each Buyer acknowledges that because of the $100,000 threshold established in Section 7.2(a), one or more Buyers may be compensated under such section while another Buyer or Buyers is not so compensated because of the operation of such $100,000 threshold. In order to correct the inequities which might otherwise result, each Buyer agrees to contribute such amounts to such other Buyers as may be necessary so that, after giving effect to all such contributions, each Buyer has received (i) the amount it would have received had there been no $100,000 threshold in Section 7.2(a), (ii) multiplied by a fraction, the numerator of which is the aggregate of all indemnity payments actually paid under Section 7.2(a) and the denominator of which is the aggregate of all indemnity payments actually paid under Section 7.2(a) plus all indemnity amounts actually offset against the $100,000 threshold. Similarly, each Buyer acknowledges that because of the $100,000 threshold in Section 7.2(b), one or more Buyers could be required to make indemnity payments under such section while another Buyer or Buyers is not so required because of the operation of such $100,000 threshold. Each Buyer agrees to contribute such amounts to such other Buyers as may be necessary so that, after giving effect to all such contributions, each Buyer has paid an indemnity amount equal to (i) the amount it would have paid had there been no $100,000 threshold in Section 7.2(b), (ii) multiplied by a fraction, the numerator of which is the aggregate of all indemnity payments actually paid under Section 7.2(b) and the denominator of which is the aggregate of all indemnity payments actually paid under Section 7.2(b) plus all indemnity amounts actually offset against the $100,000 threshold. Concentra shall provide WCAS Capital Partners III, L.P. ("WCAS CP III") with information relating to any amounts paid or offset under Sections 7.2(a) or 7.2(b), within 30 days of the date of each such payment or offset. WCAS will provide such information to its independent accountants who will, no later than February 28 (or 29) of each year determine the contribution amounts, contribution payors and contribution payees for the previous calendar year and provide notice to each Buyer as to its determinations under this Section 7.2(c). Those Buyers 20 who are required to make contributions shall pay such amounts to WCAS CP III's independent accountants within 30 days of the receipt of such notice. Such accountants will in turn, make payments to the contribution payees in accordance with the determinations set forth in the notice. Buyers agree that the determination of WCAS CP III's independent accounts as to all matters relating to this Section 7.2(c) shall be conclusive and binding on all parties, absent manifest error. ARTICLE 8 TAG-ALONG AND DRAG-ALONG RIGHTS SECTION 8.1 TAG-ALONG RIGHTS. (a) Until the earlier of (1) the second anniversary of the date the Debentures are first issued and (2) the date the Buyers sell at least 50% of the outstanding Debentures, with respect to any proposed Transfer by WCAS CP III (the "SELLING DEBENTUREHOLDER") of a majority of the Debentures held by WCAS CP III to any Person (including an underwriter or an initial purchaser in connection with an offering pursuant to Rule 144A or Regulation S of the Securities Act or in a Public Offering pursuant to a bona fide sale to the public) (any such transaction, a "PROPOSED SALE"), each Buyer (other than WCAS CP III) (a "TAGGING DEBENTUREHOLDER") will have the right to require the Selling Debentureholder to include in such Proposed Sale a face amount of the Debentures equal to up to the product (rounded up to the nearest whole number) of (i) the quotient determined by dividing (A) the aggregate face amount of the Debentures owned by such Tagging Debentureholders by (B) the aggregate face amount of the Debentures owned by WCAS CP III and the Tagging Debentureholders and (ii) the total face amount of the Debentures proposed to be directly or indirectly Transferred to the transferee or acquiring Person in the Proposed Sale (a "PROPOSED TRANSFEREE"), at the same price per face amount of the Debentures and upon the same terms and conditions (including, without limitation, time of payment, form of consideration, inclusion of Warrants and adjustments to purchase price) as the Selling Debentureholder; PROVIDED that in order to be entitled to exercise its right to sell Debentures to the Proposed Transferee pursuant to this Section 8.1(a), each Tagging Debentureholder (x) shall agree to the same covenants with respect to such Tagging Debentureholders, as appropriate, as the Selling Debentureholder agrees to in connection with the Proposed Sale; PROVIDED, however, that the aggregate amount of liability of such Tagging Debentureholder with respect to such covenants shall not exceed the proceeds to such Tagging Debentureholder in connection with the Proposed Sale, and (y) shall make such representations and warranties concerning its title to the Debentures (and Warrants, if applicable) to be sold in connection with the Proposed Sale and its authority to enter into and consummate the Proposed Sale as the Selling Debentureholder makes, but shall not be required to make any other representations and warranties or indemnities other than with respect to its own representations and warranties. (b) Each Tagging Debentureholder will be responsible for funding its proportionate share of any escrow arrangements in connection with the Proposed Sale and for its proportionate share of any withdrawals therefrom, including without limitation any such 21 withdrawals that are made with respect to claims arising out of agreements, covenants, representations, warranties or other provisions relating the Proposed Sale that were made by the Tagging Debentureholder. (c) Each Tagging Debentureholder will be responsible for its proportionate share of the reasonable fees, discounts, commissions and other out-of-pocket expenses (collectively, "COSTS") of the Proposed Sale to the extent not paid or reimbursed by Concentra, the Proposed Transferee or another Person (other than the Selling Debentureholder); PROVIDED that the Proposed Sale is consummated and the liability for such Costs shall not exceed the total purchase price received by such Tagging Debentureholder for such Debentures (and Warrants, if applicable). The Selling Debentureholder shall be entitled to estimate the Tagging Debentureholders' proportionate share of such Costs and to withhold such amounts from payments to be made to the Tagging Debentureholder at the time of closing of such Proposed Sale; PROVIDED that (i) such estimate shall not preclude the Selling Debentureholder from recovering additional amounts from the Tagging Debentureholder in respect of such Tagging Debentureholder's proportionate share of such Costs and (ii) the Selling Debentureholder shall reimburse the Tagging Debentureholder to the extent actual amounts are ultimately less than the estimated amounts or any such amounts are paid by the Company, the Proposed Transferee or another Person (other than the Selling Debentureholder). (d) The Selling Debentureholder will give notice to Concentra of each Proposed Sale not more than five days after such Selling Debentureholder has determined to effect a Proposed Sale, setting forth the face amount of Debentures (and Warrants, if applicable) proposed to be so Transferred, the manner in which the Proposed Sale will be effected, the name and address of the Proposed Transferee (if applicable), the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the Selling Debentureholder will provide such information, to the extent reasonably available to the Selling Debentureholder, relating to such non-cash consideration as each of the Tagging Debentureholders may reasonably request in order to evaluate such non-cash consideration) and other terms and conditions of the Proposed Sale. If any holders of the Debentures are given an option as to the form and amount of consideration to be received, all holders of the Debentures shall be given the same option. In the event that any of the terms and/or conditions set forth in the notice are thereafter amended in any respect, the Selling Debentureholder shall also give written notice of the amended terms and conditions of the Proposed Sale to Concentra, and each Tagging Debentureholder shall be permitted to cancel its exercise of its rights under this Section 8.1 upon delivery of written notice to Concentra to such effect and shall be released from its obligation hereunder. Upon its receipt of any such notice or amended notice, Concentra shall promptly, but in all events within three (3) Business Days of its receipt thereof, forward copies thereof to each of the Tagging Debentureholders. The Selling Debentureholder will deliver or cause to be delivered to each Tagging Debentureholder copies of all transaction documents relating to the Proposed Sale promptly as the same become available. The tag-along rights provided by this Section 8.1 must be exercised by the Tagging Debentureholders within 10 Business Days following receipt of the notice required by the preceding sentence by delivery of a 22 written notice to the Selling Debentureholder indicating its desire to exercise its rights and specifying the face amount of the Debentures it desires to sell (the "TAG-ALONG NOTICE"). The Tagging Debentureholders will be entitled under this Section 8.1 to Transfer to the Proposed Transferee the face amount of the Debentures calculated in accordance with Section 8.1(a). (e) Any Tagging Debentureholder participating in the Proposed Sale shall deliver to Concentra, as agent for such Tagging Debentureholder, for transfer to the Proposed Transferee one or more Debentures (and Warrants, if applicable), properly endorsed for transfer and with all transfer taxes paid and stamps affixed, which represent the face amount of the Debentures (and Warrants, if applicable) that such Tagging Debentureholder elects to dispose of pursuant to paragraph (d) above. The consummation of such proposed disposition shall be subject to the sole discretion of the Selling Debentureholder, who shall have no liability or obligation whatsoever to any Tagging Debentureholder participating therein other than to obtain for such Tagging Debentureholder the same terms and conditions as those of the Selling Debentureholder. Upon the consummation of any such sale, Concentra (i) shall transfer to the Proposed Transferee a Debenture or Debentures representing the face amount of the Debentures to be disposed of by any Tagging Debentureholders (and Warrants, if applicable) and (ii) shall promptly thereafter remit to each Tagging Debentureholder (i) that portion of the proceeds of the disposition to which such Tagging Debentureholder is entitled by reason of such participation and (ii) Debentures or Warrants, as the case may be, representing any balance of face amount of the Debentures or any number of Warrants that were not so disposed of (or all of the Debentures and Warrants, in the event the proposed disposition is not consummated). (f) If any Tagging Debentureholder exercises its rights under this Section 8.1, the closing of the purchase of the Debentures (and Warrants, if applicable) with respect to which such rights have been exercised will take place concurrently with the closing of the sale of the Selling Debentureholder's Debentures (and Warrants, if applicable) to the Proposed Transferee. If by the end of ninety (90) days following the date of delivery of the notice of the Proposed Sale provided by Concentra pursuant to Section 8.1(d), the Selling Debentureholder and the Proposed Transferee have not completed the Proposed Sale, each Tagging Debentureholder shall be released from its obligations under this Section 8.1, and the Tag-Along Notices shall be null and void, and it shall be necessary for the terms of this Section 8.1 to be separately complied with in order to consummate such Proposed Sale pursuant to this Section 8.1. SECTION 8.2. DRAG-ALONG RIGHTS. (a) Until the earlier of (1) the second anniversary of the date the Debentures are first issued and (2) the date the Buyers sell at least 50% of the outstanding Debentures, if WCAS CP III (the "DRAGGING DEBENTUREHOLDER") decides to, and does, sell (including to an underwriter or an initial purchaser in a Public Offering, pursuant to a bona fide sale to the public or pursuant to Rule 144A or Regulation S under the Securities Act), all of the face amount of the Debentures then owned by the Dragging Debentureholder (a "SECTION 8.2 TRANSFER") then each Buyer (other than the Dragging Debentureholder) (collectively, the "DRAG-ALONG 23 DEBENTUREHOLDERS") hereby agrees that, if requested by the Dragging Debentureholder, it will Transfer in the Section 8.2 Transfer, subject to the other provisions of this Section 8.2, on the terms of the Section 8.2 Transfer as finally determined by the Dragging Debentureholder, including, without limitation, time of payment, form and choice of consideration, inclusion of Warrants and adjustments to purchase price, the face amount of the Debentures (and number of Warrants, if applicable) equal to the face amount of the Debentures (and number of Warrants, if applicable) owned by it multiplied by the percentage of the then outstanding face amount of Debentures (and number of Warrants) to which the Section 8.2 Transfer offer is applicable; PROVIDED, HOWEVER, Chase Equity Associates, L.P. and its transferees and assigns shall have the right to refuse to participate in any proposed Section 8.2 Transfer giving rise to the rights of the Dragging Debentureholder set forth in this Section 8.2(a) within five (5) Business Days following the receipt of the Drag-Along Notice (as defined below) by sending written notice of its refusal to the Dragging Debentureholder. (b) The Dragging Debentureholder will give notice (the "DRAG-ALONG NOTICE") to the Drag-Along Debentureholders of any Section 8.2 Transfer within five (5) Business Days following the Dragging Debentureholder's determination to effect a Section 8.2 Transfer and, in any event, not less than ten (10) Business Days prior to the proposed closing date for such Section 8.2 Transfer. The Drag-Along Notice will set forth the face amount of the Debentures (and number of Warrants, if applicable) proposed to be so Transferred, the manner in which the Section 8.2 Transfer will be effected, the name of the proposed Transferee or acquiring Person (if applicable), the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the Dragging Debentureholder will provide such information, to the extent reasonably available to the Dragging Debentureholder, relating to such non-cash consideration as the Drag-Along Debentureholders together may reasonably request in order to evaluate such non-cash consideration), the face amount of the Debentures (and number of Warrants, if applicable) sought and the other terms and conditions of the Section 8.2 Transfer. If any holders of the Debentures are given an option as to the form and amount of consideration to be received, all holders of the Debentures shall be given the same option. Each Drag-Along Debentureholder (x) shall agree to the same covenants with respect to such Drag-Along Debentureholders, as appropriate, as the Dragging Debentureholder agrees to in connection with the Section 8.2 Transfer; PROVIDED, HOWEVER, that the aggregate amount of liability of such Drag-Along Debentureholder with respect to such covenants shall not exceed the proceeds to such Drag-Along Debentureholder in connection with the Section 8.2 Transfer and (y) shall make such representations and warranties concerning its title to the Debentures (and Warrants, if applicable) to be sold in connection with the Section 8.2 Transfer and its authority to enter into and consummate the Section 8.2 Transfer as the Dragging Debentureholder makes, but shall not be required to make any other representations and warranties or indemnities other than in respect of its own representations and warranties. If the Dragging Debentureholder does not request that the Drag-Along Debentureholders participate in a Section 8.2 Transfer, then each holder of Debentures shall have the right to participate in such proposed transfer in accordance with its rights under Section 8.1 above. 24 (c) Each Drag-Along Debentureholder will be responsible for funding its proportionate share of any escrow arrangements in connection with the Section 8.2 Transfer and for its proportionate share of any withdrawals therefrom, including without limitation any such withdrawals that are made with respect to claims arising out of agreements, covenants, representations, warranties or other provisions relating the Section 8.2 Transfer that were made by the Drag-Along Debentureholder. (d) Each Drag-Along Debentureholder will be responsible for its proportionate share of the Costs of the Section 8.2 Transfer to the extent not paid or reimbursed by Concentra or another Person (other than the Dragging Debentureholder); PROVIDED that such Section 8.2 Transfer is consummated and the liability for such Costs shall not exceed the total purchase price received by such Drag-Along Debentureholder for such Debentures (and Warrants, if applicable). The Dragging Debentureholder shall be entitled to estimate the Drag-Along Debentureholders' proportionate share of such Costs and to withhold such amounts from payments to be made to the Drag-Along Debentureholder at the time of closing of the Section 8.2 Transfer; PROVIDED that (i) such estimate shall not preclude the Dragging Debentureholder from recovering additional amounts from the Drag-Along Debentureholder in respect of such Drag-Along Debentureholder's proportionate share of such Costs and (ii) the Dragging Debentureholder shall reimburse the Drag-Along Debentureholder to the extent actual amounts are ultimately less than the estimated amounts or any such amounts are paid by Concentra or another Person (other than the Dragging Debentureholder). If the Section 8.2 Transfer is not consummated within 180 days from the date of the Drag-Along Notice, the Dragging Debentureholder must deliver another Drag-Along Notice in order to exercise its rights under this Section 8.2 with respect to such Section 8.2 Transfer. (e) At the closing of such Section 8.2 Transfer, each of the Dragging Debentureholders shall deliver one or more Debentures (and Warrants, if applicable), properly endorsed for transfer and with all transfer taxes paid and stamps affixed, which represent the face amount of the Debentures (and Warrants, if applicable) then held by it and to be sold in such sale, duly endorsed for transfer, against payment of the purchase price therefor by wire transfer to the account or accounts specified by such Drag-Along Debentureholder.
