Tenant may pay Rent by check, Automated Clearing House (ACH) payment processing or wire transfer, and Landlord shall provide such information as requested by Tenant in order to enable Tenant to make payment by such any such method.

3.3 Tax Expenses.

(a) Tenant will pay all Tax Expenses that become due on and after the Term Commencement Date directly to the appropriate taxing authorities or other payee. All bills, notices and correspondence shall be sent directly to Tenant from the applicable taxing authority. If the applicable taxing authority shall not permit bills, notices and correspondence to be sent directly to Tenant, Landlord shall provide Tenant, within ten (10) days of receipt, copies of any bills, notices and correspondence Landlord receives from any taxing authority. Tenant will furnish to Landlord (and such other parties as Landlord may otherwise reasonably designate) the paid receipts issued by the appropriate taxing authorities or other payee not less than fifteen (15) days prior to the date any Tax Expenses would first become delinquent. If the termination of the Lease occurs on a date other than the final day of the fiscal property tax year, the Tax Expenses for the partial property tax year will be prorated based on the number of days during such property tax year occurring during the Term, and Tenant will pay to Landlord the prorated portion of the Tax Expenses on or before the termination of the Lease or such later date as the parties can ascertain the amount of the Tax Expenses and make the proration contemplated above. Notwithstanding anything herein to the contrary, if any bill for Tax Expenses includes taxes or other expenses related to Landlord’s Adjacent Land or property other than the Land, Tenant shall only be responsible to pay for the Tax Expenses attributable to the Land, which amount shall be prorated based on the assessed value of the unimproved real property and the total number of acres contained in the Land and other property included in such tax bill.

(b) In the event Landlord is directly assessed for the Tax Expenses on the Land or the bill therefor includes taxes on Landlord’s Adjacent Land or other property, Landlord agrees to pay on or before the date due such ad valorem taxes and assessments, including the taxes owing on the Land (for which Tenant shall reimburse Landlord as provided herein). A copy of the bill for all such taxes owed by Landlord and evidence of payment in full shall be sent to Tenant when Tenant has a reasonable question as to whether such taxes have been paid and following a written request. In the event Landlord fails to pay such amounts when due, Tenant shall have the right, at its option, to make such payment on behalf of Landlord and credit such amount against payments owed by Tenant to Landlord under this Lease or the Oxygen Supply Agreement as Tenant elects, or to require reimbursement therefor from Landlord.

(c) Tenant may, in the exercise of its good faith business judgment, contest any assessment or the imposition of any Tax Expenses against the Tenant Improvements. Landlord agrees, at Tenant’s request, to cooperate with Tenant as may be legally necessary in connection with any such contest and, at no out-of-pocket expense to Landlord and requiring only minimal time by Landlord’s personnel (e.g., executing appeals of tax valuations, but with no obligation to prepare such appeals), to cooperate reasonably in such proceedings.

3.4 Liens. Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon Landlord’s interest in Land (other than liens securing payment of the Tax Expenses which are not yet due and payable). Further, Tenant shall not voluntarily create any lien or encumbrance of any kind whatsoever on the interest of Tenant in the Land without the prior written consent of Landlord (which consent shall not be unreasonably withheld, conditioned or delayed). Tenant may not suffer or permit mechanics or materialmen or others to place liens against the Land in connection with work or services they claim to have performed at the request of Tenant or any Tenant related parties or in connection with materials they claim to have furnished to Tenant, any Tenant related parties or the Land at the request of Tenant or any Tenant related parties, and, in case of the attachment of any such lien or Landlord’s receipt of any notice of any such lien, Tenant must discharge the lien by either settling the lien claim or providing adequate security to ensure settlement of such claim (such as a bond or escrow) within thirty (30) days following the earlier to occur of the date (a) on which Tenant has actual knowledge of the existence of such lien or (b) Landlord delivers notice of the lien to Tenant. Notwithstanding anything to the contrary set forth in this Lease, if Tenant fails to discharge the lien as provided above within such thirty (30) day period, Landlord may immediately take all action necessary to release and remove the lien without any duty to investigate the validity of the lien claim, and, within fifteen (15) days after Landlord’s demand, Tenant shall pay to Landlord all sums, costs and expenses, including reasonable attorneys’ fees and costs, Landlord incurs in connection with the release and removal of the lien. If applicable law permits Tenant to furnish a bond or other security and thereby compel lien claimants to assert claims against the surety providing the bond in lieu of enforcing lien rights against the property owner’s property, Landlord will consider Tenant as having released and removed a lien against the Land if Tenant furnishes the bond in accordance with the requirements of the applicable law.

3.5 Tax Abatements. Tenant may elect to seek certain abatements of any of the Tax Expenses which may be imposed upon the Tenant Improvements. Landlord agrees at Tenant’s request to reasonably cooperate with Tenant in any abatement proceedings at no out-of-pocket expense to Landlord and requiring only minimal time by Landlord’s personnel and, subject to Landlord’s prior approval, execute such documents which may be legally necessary in connection with any such abatement request.

11.3 Conditions of Indemnification. The respective rights and obligations of the Parties and the other indemnitees under this Article 11 with respect to claims trailing from the assertion of liability by third parties shall be subject to the following terms and conditions:

(a) Within ten (10) Business Days (or such earlier time as might be required to avoid prejudicing the position of the Party from whom indemnification is sought (the “Indemnifying Party”)) after receipt of notice of commencement of any action evidenced by service of process or other legal pleading, the Person claiming to be indemnified under the terms of this Article 11 (the “Indemnified Person”) shall give the Indemnifying Party written notice thereof, together with a copy of such claim, process or other legal pleading. Failure of the Indemnified Person to give such notice will not reduce or relieve the Indemnifying Party of liability hereunder unless and to the extent that the Indemnifying Party was precluded from defending such claim, action, suit or proceeding as a result of the failure of the Indemnified Person to give such notice. In any event, the failure to so notify shall not relieve the Indemnifying Party from any liability that it may have to the Indemnified Person otherwise than under this Article 11.

(b) Each Indemnified Person shall have the right, but not the obligation, to contest, defend and litigate any claim, action, suit or proceeding by any third party alleged or asserted against it arising out of any matter in respect of which it is entitled to be indemnified hereunder and the reasonable costs and expenses thereof (including reasonable attorneys’ fees and expenses and expert witness fees) shall be subject to the said indemnity as set forth herein; provided that the Indemnifying Party shall have the right to retain counsel acceptable to the Indemnified Person to defend such third party claim, at the Indemnifying Party’s sole cost and expense, unless and until the Indemnified Person notifies the Indemnifying Party that: (i) such third party claim is reasonably likely to result in Damages at least a material portion of which would not be fully indemnified by the Indemnifying Party, (ii) such third party claim is reasonably likely to have a material adverse effect on the business or financial condition of the Indemnified Person, (iii) the Indemnifying Party is also a Person against whom the third party claim is made and the Indemnified Person reasonably determines that joint representation would be inappropriate, (iv) the third party claim seeks injunctive, equitable or other non-monetary relief affecting the Indemnified Person or any of its Affiliates, or (v) the Indemnifying Party fails to take reasonable steps necessary to diligently defend such third party claim and protect the interests of the Indemnified Person that are reasonably inferable or otherwise timely communicated. If the Indemnifying Party has the right to assume the defense of the third party claim and it elects to do so, it must notify the Indemnified Person and assume the defense (with counsel acceptable to the Indemnified Person), as promptly as possible after receipt of the Indemnified Person’s notice of the claim (but in any case within ten (10) Business Days after receipt of such notice or such earlier time reasonably necessary to timely respond to the third party claim). If the Indemnifying Party does not provide notice to the Indemnified Person and assume the defense of the third party claim within such period of time, the Indemnifying Party shall not be entitled to assume the defense of the third party claim unless otherwise agreed to by the Indemnified Person.

(c) If the Indemnifying Party assumes the defense of the third party claim, (i) such assumption will conclusively establish that the claims made in such third party claim are within the scope of and subject to indemnification by the Indemnifying Party, and (ii) the Indemnifying Party shall not settle, compromise or discharge such third party claim without the prior written consent of the Indemnified Person; provided that the prior written consent of the Indemnified Person shall not be required for any settlement that (A) only requires the payment of money that is paid by the Indemnifying Party, and does not provide for injunctive, equitable or other non-monetary relief affecting the Indemnified Person or any of its Affiliates, (B) does not include a finding or admission of any violation of applicable law, any violation of the rights of any Person, or any admission of guilt, and (C) provides for a full release and discharge of the Indemnified Person. Upon assumption by the Indemnifying Party of the defense of the third party claim, the Indemnifying Party shall reimburse the Indemnified Person for the reasonable costs and expenses previously incurred by it prior to the assumption of such defense by the Indemnifying Party. The Indemnifying Party shall keep the Indemnified Person informed of all material developments relating to or in connection with the third party claim and the defense thereof, and make available to the Indemnified Person and its counsel, all information and documents available to the Indemnifying Party related to the third party claim. The Indemnified Person shall provide reasonable assistance to the Indemnifying Party, at the Indemnifying Party’s expense, in connection with such claim, action, suit or proceeding.

(d) If any of the circumstances described in the clauses (i) through (v) of Section 11.3(b) exist prior to or arise after the Indemnifying Party has assumed the defense of the third party claim, or until such time as the Indemnifying Party assumes the defense of the third party claim, if applicable, the Indemnified Person shall have the sole right to assume the defense of the third party claim, with counsel of its choice (provided that such counsel has no ethical conflict of interest with the Indemnifying Party that is not waiveable) and to defend, settle and compromise such third party claim. The Indemnifying Party shall be liable for all costs or expenses (including reasonable attorneys’ fees and expenses and expert witness fees) paid or incurred by the Indemnified Person in connection therewith. In addition, the Indemnifying Party shall render, at its own cost, such assistance as may reasonably be requested in order to ensure the proper and adequate defense of the third party claim and cooperate in the defense of the third party claim. In the event the Indemnifying Party assumes control of the defense, the Indemnified Person shall have the right to employ its own counsel, such counsel may participate in such claim, action, suit or proceeding, and the Indemnifying Party shall reasonably cooperate with the Indemnified Person in connection with such participation, but the fees and expenses of such counsel following assumption of the defense by the Indemnifying Party shall be at the expense of such Indemnified Person, except as otherwise provided above and unless: (i) the employment of counsel by such Indemnified Person has been authorized in writing by the Indemnifying Party; (ii) outside counsel of the Indemnified Person shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Person in the conduct of the defense of such action; or (iii) the Indemnified Person shall have reasonably concluded and specifically notified the Indemnifying Party either that there may be specific defense available to it which are different from or additional to those available to the Indemnifying Party. If any of the preceding clauses shall be applicable, then counsel for the Indemnified Person shall have the right to direct the defense of such claim, action, suit or proceeding on behalf of the Indemnified Person and the reasonable fees and expenses of such counsel shall be reimbursed by the Indemnifying Party.

ARTICLE 12.
LIMITATION ON DAMAGES

EXCEPT AS MAY RESULT FROM THE INDEMNIFICATION OBLIGATIONS WITH RESPECT TO THIRD PARTY CLAIMS ARISING UNDER Article 11, NEITHER PARTY WILL BE LIABLE TO THE OTHER PARTY FOR ANY INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL, OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS, SALES, OR OTHER SIMILAR DAMAGES) ARISING IN CONNECTION WITH THIS AGREEMENT WITHOUT REGARD TO THE NATURE OF THE CLAIM OR THE UNDERLYING THEORY OR CAUSE OF ACTION (WHETHER IN CONTRACT, TORT, STRICT LIABILITY, EQUITY, OR ANY OTHER THEORY OF LAW) ON WHICH SUCH DAMAGES ARE BASED.
