As PPM is the customer of record for the single meters for all water/sewer, electric and natural gas (the “Shared Utilities”) servicing the Entire Premises (and specifically excluding GTC space on the 4^th floor of the Building), PPM shall receive all bills for the generation, delivery, and consumption of such Shared Utilities for both Parties (the “Shared Utility Costs”).

PPM shall be responsible for payment of 68% of the Shared Utility Costs.

GTC shall be responsible for payment of 32% of the Shared Utility Costs.

Subject to PPM’s right to dispute the contents of any such invoice and subject to receipt by PPM of prompt payment by GTC as required below, PPM will timely pay to the appropriate provider, the Shared Utility Costs as detailed on invoices received from such provider.

GTC shall be invoiced monthly by PPM for its 32% share of the Shared Utility Costs, which invoice shall be payable by GTC to PPM within 30 days of receipt of such invoice. Copies of all electric, natural gas and water/sewer invoices received from the applicable provider shall be provided to GTC with the monthly utilities invoice.

The Shared Systems include the following systems and all related equipment as follows:

PPM shall be responsible for the repair, maintenance and replacement of the Shared Systems, which may include, without limitation, (all in PPM’s sole discretion), the following actions: maintaining preventative maintenance programs and contracts,

Confidential

execution of required mechanical and controls repairs and upgrades, and documentation of same, in accordance with PPM’s established standard operating procedures, good manufacturing practices (where applicable), and in compliance with all applicable local, state and federal codes and regulations.

Notwithstanding the foregoing, in the event that PPM determines that replacement (as opposed to repair and/or maintenance) of all or any portion of a Shared System is necessary (the “Replaced Shared System”) and (i) PPM elects to replace such Replaced Shared System with a replacement that is not the same model as that which is being replaced; and (ii) the estimated cost (in PPM’s reasonable discretion) of the Replaced Shared System exceeds Ten Thousand Dollars ($10,000.00), then PPM agrees to consult with GTC in its determination of the vendor, model and specification of any such Replaced Shared System, and the parties shall use good faith efforts to agree on a Replaced Shared System that is mutually acceptable.

PPM shall be responsible for payment of 68% of all costs associated with PPM’s obligations under the preceding paragraph, which costs shall include, without limitation, preventative and restorative maintenance, parts, PPM and contractor labor, and applicable fees for each of these Shared Systems (the “Shared Systems Costs”).

GTC shall be responsible for payment of 32% of all Shared Systems Costs. In the event that an individual Shared System Cost capital expenditure exceeding $20,000 increases the useful life of the Shared System beyond the GTC Expiration Date, GTC’s contribution will be prorated on a straight-line basis over the useful life of the Replaced Shared System as determined by PPM in its reasonable discretion based on the portion of the useful life that occurs from the date of the expenditure to the GTC Expiration Date.

Subject to PPM’s right to dispute the contents of any such invoice (and PPM shall use reasonable efforts to dispute the contents of any such invoice if GTC requests same and GTC includes in its request to PPM a sufficiently detailed reason to believe that the invoice is incorrect or inaccurate, but without any obligation on the part of PPM to bring legal action) and subject to receipt by PPM of prompt payment by GTC as required below, PPM will timely pay the Shared Systems Costs as detailed on invoices received directly by PPM from a third party provider.

GTC shall be invoiced monthly by PPM for its 32% share of the Shared Systems Costs, which invoice shall be payable by GTC to PPM within 30 days of receipt of such invoice. Copies of all applicable third party invoices shall be provided to GTC with the monthly invoice. Except to the extent arising out of a breach by GTC of its obligations hereunder, PPM shall be responsible to the service providers for 100% of penalties, late fees and interest owed to the service providers pursuant to late payments made by PPM to such service providers. PPM reserves the right to charge a late fee (not to exceed 5% of the amount owed) to GTC for any late payments hereunder. The foregoing shall not limit PPM’s ability, at its cost, to dispute any such penalty, late fee or interest charged by a service provider.
