	(f)		Excess Funds and Cost Overruns – Tangible Costs.Any estimated Tangible Costs (which are the Tangible Costs set forth on the AFE) prepaid by Developer with respect to any well that exceed Operator’s price specified in sub-section (a) above for the Tangible Costs of the well shall be retained by Operator and shall be applied, in proportion to the share of the Working Interest owned by the Developer in the wells, to:

	(i)		the Developer’s Participants’ share of the Tangible Costs for an additional well or wells to be drilled on the Additional Well Locations; or

	(ii)		any cost overruns owed by the Developer to Operator for the Developer’s Participants’ share of the Tangible Costs of one or more of the other wells on the Well Locations.

Conversely, if Operator’s price specified in sub-section (a) above for the Developer’s Participants’ share of Tangible Costs of any well exceeds the estimated Tangible Costs (which are the Tangible Costs set forth on the AFE) prepaid by Developer for the Developer’s Participants’ share of the Tangible Costs for the well, then:

	(i)		Developer shall pay the additional price to Operator within ten (10) business days after notice from Operator that the additional price is due and owing; or

	(ii)		Developer and Operator may agree to delete or reduce Developer’s Working Interest in one or more wells to be drilled under this Agreement that have not yet been spudded to provide funds to pay the additional amounts owed by Developer to Operator. If doing so results in any excess prepaid Tangible Costs, then these funds shall be applied, in proportion to the share of the Working Interest owed by the Developer in the wells, to:

	(a)		the Developer’s Participants’ share of the Tangible Costs of an additional well or wells to be drilled on the Additional Well Locations; or

	(b)		any cost overruns owed by the Developer to Operator for the Developer’s Participants’ share of the Tangible Costs of one or more of the other wells on the Well Locations.

(iii)

Addendum to this Agreement shall be ten percent (10%) of the total price prepaid by Developer to Operator pursuant to Section 4(b) of this Agreement or any Addendum hereto. The Developer’s Participants’ share of the Tangible Costs of any one well drilled under this Agreement shall be determined, subject to the preceding sentence, taking into account the Developer’s share of all of the Tangible Costs of all of the wells to be drilled under this Agreement and any Addendum hereto.

The Exhibits to this Agreement with respect to the affected wells shall be amended as appropriate.

Title Examination of Well Locations, Developer’s Acceptance and Liability; Additional Well Locations.

	(a)		Title Examination of Well Locations, Developer’s Acceptance and Liability.The Developer acknowledges that Operator has furnished Developer with the title opinions identified on Exhibit A, and other documents and information that Developer or its counsel has requested in order to determine the adequacy of the title to the Initial Well Locations and leased premises subject to this Agreement. The Developer accepts the title to the Initial Well Locations and leased premises and acknowledges and agrees that, except for any loss, expense, cost, or liability caused by the breach of any of the warranties and representations made by the Operator in Section l(b), any loss, expense, cost or liability whatsoever caused by or related to any defect or failure of the title shall be the sole responsibility of and shall be borne entirely by the Developer.

	(b)		Additional Well Locations.Before beginning drilling of any well on any Additional Well Location, Operator shall conduct, or cause to be conducted, a title examination of the Additional Well Location, in order to obtain appropriate abstracts, opinions and certificates and other information necessary to determine the adequacy of title to both the applicable Lease and the fee title of the lessor to the premises covered by the Lease. The results of the title examination and such other information as is necessary to determine the adequacy of title for drilling purposes shall be submitted to the Developer for its review and acceptance. No drilling on the Additional Well Locations shall begin until the title has been accepted in writing by the Developer. After any title has been accepted by the Developer, any loss, expense, cost, or liability whatsoever, caused by or related to any defect or failure of the title shall be the sole responsibility of and shall be borne entirely by the Developer, unless such loss, expense, cost, or liability was caused by the breach of any of the warranties and representations made by the Operator in Section l(b).

Operations Subsequent to Completion of the Wells; Fee Adjustments; Extraordinary Costs; Pipelines; Price Determinations; Plugging and Abandonment.

	(a)		Operations Subsequent to Completion of the Wells.Beginning with the month in which a well drilled under this Agreement begins to produce, Operator shall be entitled to an operating fee of $362 per month for each well being operated under this Agreement, which operating fee shall be proportionately reduced, on a well-by-well basis, to the extent the Developer owns less than 100% of the Working Interest in a well. This fee shall be in lieu of any direct charges by Operator for its services or the provision by Operator of its equipment for normal superintendence and maintenance of the wells and related pipelines and facilities.

			If a third-party serves as the actual operator of a well for all of the Working Interest owners of the well, then the operating fee payable to the Operator under this Agreement for the well shall be $25 per month, plus the actual third-party operator’s monthly charges. The $25 included in the monthly operating fee for the well shall be retained by Operator each month for reviewing the costs and expenses charged by the third-party operator and monitoring the third-party operator’s accounting and production records for the well on behalf of the Developer, and the remainder of the monthly operating fee for the well shall be paid by Operator to the actual third-party operator of the well.

The operating fees shall cover all normal, regularly recurring operating expenses for the production, delivery and sale of natural gas, including without limitation:

(i)

well tending, routine maintenance and adjustment;

	(ii)		reading meters, recording production, pumping, maintaining appropriate books and records;

	(iii)		preparing reports to the Developer and government agencies; and

	(iv)		collecting and disbursing revenues.

The operating fees shall not cover costs and expenses related to the following:

	(i)		the production and sale of oil;

	(ii)		the collection and disposal of salt water or other liquids produced by the wells;

	(iii)		the rebuilding of access roads; and

	(iv)		the purchase of equipment, materials or third-party services;

			which, subject to the provisions of sub-section (c) of this Section 6, shall be invoiced by Operator to the Developer on a monthly basis, and shall be paid by the Developer within ten (10) business days after notice from Operator that the additional amounts are due and owing in proportion to the share of the Working Interest owned by the Developer in the wells.

			Any well that is temporarily abandoned or shut-in continuously for an entire calendar month shall not be considered a producing well for purposes of determining the number of wells in the month subject to the operating fee.

	(b)		Fee Adjustments.The monthly operating fee set forth in sub-section (a) above may be adjusted by Operator annually, as of the first day of January (the “Adjustment Date”) of each year, beginning January 1, 2007. This adjustment, if any, shall not exceed the percentage increase in the average weekly earnings of “Crude Petroleum, Natural Gas, and Natural Gas Liquids” workers, as published by the U.S. Department of Labor, Bureau of Labor Statistics, and shown in Employment and Earnings Publication, Monthly Establishment Data, Hours and Earning Statistical Table C-2, Index Average Weekly Earnings of “Crude Petroleum, Natural Gas, and Natural Gas Liquids” workers, SIC Code #131-2, or any successor index thereto, since January l, 2006, in the case of the first adjustment, and since the previous Adjustment Date, in the case of each subsequent adjustment.

			In addition, the monthly operating fee set forth in sub-section (a) above for any given well or wells being operated under this Agreement may be increased beyond the annual adjustment described in the prior paragraph without advance notice to the Developer, from time to time to the competitive rate in the area where the well(s) are situated, as determined by the Operator in its sole discretion.

	(c)		Extraordinary Costs.Without the prior written consent of the Developer, pursuant to a written estimate submitted by Operator, Operator shall not undertake any single project or incur any extraordinary cost with respect to any well being produced under this Agreement that is reasonably estimated to result in an expenditure of more than $5,000, unless the project or extraordinary cost is necessary for the following:

	(i)		to safeguard persons or property; or

	(ii)		to protect the well or related facilities in the event of a sudden emergency.

			In no event, however, shall the Developer be required to pay for any project or extraordinary cost arising from the negligence or misconduct of Operator, its agents, servants, employees, subcontractors, licensees, or invitees.

			All extraordinary costs incurred and the cost of projects undertaken under this section with respect to a well being produced under this Agreement shall be billed to the Developer at the invoice cost of third-party services performed or materials purchased, together with a reasonable charge by Operator for any services performed directly by it, in proportion to the share of the Working Interest owned by the Developer in the

			well. Operator shall have the right to require the Developer to pay in advance all or a portion of the estimated costs of a project undertaken under this section, before undertaking the project, in proportion to the share of the Working Interest owned by the Developer in the well or wells.

	(d)		Pipelines.Developer shall have no interest in the pipeline gathering system, which gathering system shall remain the sole property of Operator or its Affiliates and shall be maintained at their sole cost and expense.

	(e)		Price Determinations.Notwithstanding anything in this Agreement to the contrary, the Developer shall pay all costs in proportion to the share of the Working Interest owned by the Developer in the wells with respect to obtaining price determinations under and otherwise complying with the Natural Gas Policy Act of 1978 and the implementing state regulations. This responsibility shall include, without limitation, preparing, filing, and executing all applications, affidavits, interim collection notices, reports and other documents necessary or appropriate to obtain price certification, to effect sales of natural gas, or otherwise to comply with the Act and the implementing state regulations.

			Operator agrees to furnish the information and render the assistance as the Developer may reasonably request in order to comply with the Act and the implementing state regulations without charge for services performed by its employees.

	(f)		Plugging and Abandonment.The Developer shall have the right to direct Operator to plug and abandon any well that has been completed under this Agreement as a producer. In addition, Operator shall not plug and abandon any well that has been drilled and completed as a producer under this Agreement before obtaining the written consent of the Developer. However, if the Operator determines that any well drilled and completed under this Agreement as a producer should be plugged and abandoned in accordance with the generally accepted and customary oil and gas field practices and techniques then prevailing in the geographic area of the well location, and makes a written request to the Developer for authority to plug and abandon the well and the Developer fails to respond in writing to the request within forty-five (45) days following the date of the request, then the Developer shall be deemed to have consented to the plugging and abandonment of the well.

			All costs and expenses related to plugging and abandoning wells that have been drilled and completed under this Agreement as producing wells shall be borne and paid by the Developer in proportion to the share of the Working Interest owned by the Developer in the wells. Also, at any time after one (1) year from the date each well drilled and completed under this Agreement is placed into production, Operator shall have the right to deduct each month from the proceeds of the sale of the production from the well up to $200, in proportion to the share of the Working Interest owned by the Developer in the well, for the purpose of establishing a fund to cover the Operator’s estimate of the Developer’s share of the costs of eventually plugging and abandoning the well. All of these funds shall be deposited by Operator in a separate interest bearing escrow account for the account of the Developer, and the total amount so retained and deposited shall not exceed Operator’s reasonable estimate of Developer’s share of the costs of eventually plugging and abandoning the well.

Billing and Payment Procedure with Respect to Operation of Wells; Disbursements; Separate Account for Sale Proceeds; Records and Reports; Additional Information.

(a)

Billing and Payment Procedure with Respect to Operation of Wells.Operator shall promptly and timely pay and discharge on behalf of the Developer, in proportion to the share of the Working Interest owned by the Developer in the wells, the following:

	(i)		all expenses and liabilities payable and incurred by reason of its operation of the wells in accordance with this Agreement, such as severance taxes, royalties, overriding royalties, operating fees, and pipeline gathering charges; and

	(ii)		any third-party invoices received by Operator with respect to the Developer’s share of the costs and expenses incurred in connection with the operation of the wells.

			Operator, however, shall not be required to pay and discharge any of the above costs and expenses that are being contested in good faith by Operator.

			Operator shall:

	(i)		deduct the foregoing costs and expenses from the Developer’s share of the proceeds of the oil and/or gas sold from the wells; and

	(ii)		keep an accurate record of the Developer’s account, showing expenses incurred and charges and credits made and received with respect to each well.

			If the Developer’s share of the proceeds of the oil and/or gas sold from the wells is insufficient to pay the costs and expenses described above, then Operator shall promptly and timely pay and discharge the costs and expenses, in proportion to the share of the Working Interest owned by the Developer in the wells, and prepare and submit an invoice to the Developer each month for those costs and expenses. The invoice shall be accompanied by the form of statement specified in sub-section (b) below, and shall be paid by the Developer within ten (10) business days of its receipt.

	(b)		Disbursements.Operator shall disburse to the Developer, on a monthly basis, the Developer’s share of the proceeds received from the sale of oil and/or gas sold from the wells operated under this Agreement, less:

	(i)		the amounts charged to the Developer under sub-section (a); and

	(ii)		the amount, if any, withheld by Operator for future plugging costs pursuant to sub-section (f) of Section 6.

Each disbursement made and/or invoice submitted to the Developer pursuant to sub-section (a) above shall be accompanied by a statement from the Operator itemizing with respect to each well:

	(i)		the total production of oil and/or gas since the date of the last disbursement or invoice billing period, as the case may be, and the Developer’s share of the production;

	(ii)		the total proceeds received from any sale of the production, and the Developer’s share of the proceeds;

	(iii)		the costs and expenses deducted from the proceeds and/or being billed to the Developer pursuant to sub-section (a) above;

	(iv)		the amount withheld for future plugging costs; and

	(v)		any other information as Developer may reasonably request, including without limitation copies of all third-party invoices listed on the statement for the period.

	(c)		Separate Account for Sale Proceeds.Operator agrees to deposit all proceeds from the sale of oil and/or gas sold from the wells operated under this Agreement in a separate checking account maintained by Operator. This account shall be used solely for the purpose of collecting and disbursing funds constituting proceeds from the sale of production under this Agreement.

	(d)		Records and Reports.In addition to the statements required under sub-section (b) above, Operator, within seventy-five (75) days after the completion of each well drilled, shall furnish the Developer with a detailed statement itemizing with respect to the well the total costs and charges under Section 4(a) and the Developer’s share of the costs and charges, and any other information as is necessary to enable the Developer:

(i)

to allocate any extra costs incurred with respect to the well between Tangible Costs and Intangible Drilling Costs; and

(ii)

to determine the amount of the investment tax credit or marginal well production tax credit, if applicable.

(e)

Additional Information.Operator shall promptly furnish the Developer with any additional information as it may reasonably request, including without limitation geological, technical, and financial information, in the form as may reasonably be requested, pertaining to any phase of the operations and activities governed by this Agreement. The Developer and its authorized employees, agents and consultants, including independent accountants shall, at Developer’s sole cost and expense:

	(i)		on at least ten (10) days’ written notice to Operator have access during normal business hours to all of Operator’s records pertaining to operations under this Agreement, including without limitation, the right to audit the books of account of Operator relating to all receipts, costs, charges, expenses and disbursements and information regarding the separate account required under sub-section (c); and

	(ii)		have access, at its sole risk, to any wells drilled by Operator under this Agreement at all times to inspect and observe any machinery, equipment and operations.

Operator’s Lien; Right to Collect From Oil or Gas Purchaser.

(a)

Operator’s Lien.To secure the payment of all sums due from Developer to Operator under this Agreement, the Developer grants Operator a first and preferred lien on and security interest in the following:

	(i)		the Developer’s interest in the Leases covered by this Agreement;

	(ii)		the Developer’s interest in oil and gas produced under this Agreement and its share of the proceeds from the sale of the oil and gas; and

	(iii)		the Developer’s interest in materials and equipment under this Agreement.

(b)

Right to Collect From Oil or Gas Purchaser.If the Developer fails to timely pay any amount owing under this Agreement by it to the Operator, then Operator, without prejudice to other existing remedies, may collect and retain from any purchaser or purchasers of oil or gas the Developer’s share of the proceeds from the sale of the oil and gas until the amount owed by the Developer, plus twelve percent (12%) interest on a per annum basis, and any additional costs (including without limitation actual attorneys’ fees and costs) resulting from the delinquency, has been paid. Each purchaser of oil or gas shall be entitled to rely on Operator’s written statement concerning the amount of any default.

Successors and Assigns; Transfers; Appointment of Agent.

(a)

Successors and Assigns.This Agreement shall be binding on and inure to the benefit of the undersigned parties and their respective successors and permitted assigns. However, without the prior written consent of the Developer, the Operator may not assign, transfer, pledge, mortgage, hypothecate, sell or otherwise dispose of any of its interest in this Agreement, or any of its rights or obligations under this Agreement. Notwithstanding, this consent shall not be required in connection with:

	(i)		the assignment of work to be performed for Operator to subcontractors, it being understood and agreed, however, that any assignment to Operator’s subcontractors shall not in any manner relieve or release Operator from any of its obligations and responsibilities under this Agreement;

	(ii)		any lien, assignment, security interest, pledge or mortgage arising under Operator’s present or future financing arrangements; or

	(iii)		the liquidation, merger, consolidation, or other corporate reorganization or sale of substantially all of the assets of Operator.

Further, in order to maintain uniformity of ownership in the wells, production, equipment, and leasehold interests covered by this Agreement, and notwithstanding any other provision of this Agreement to the contrary, the Developer shall not, without the prior written consent of Operator, sell, assign, transfer, encumber, mortgage or otherwise dispose of any of its interest in the wells, production, equipment or leasehold interests covered by this Agreement unless the disposition encompasses either:

	(i)		the entire interest of the Developer in all wells, production, equipment and leasehold interests subject to this Agreement; or

	(ii)		an equal undivided interest in all such wells, production, equipment, and leasehold interests.

(b)

Transfers.Subject to the provisions of sub-section (a) above, any sale, encumbrance, transfer or other disposition made by the Developer of its interests in the wells, production, equipment, and/or leasehold interests covered by this Agreement shall be made:

	(i)		expressly subject to this Agreement;

	(ii)		without prejudice to the rights of the Operator; and

	(iii)		in accordance with and subject to the provisions of the Leases covering the Well Locations.

However, all the co-owners shall continue to have the right to enter into and execute all contracts or agreements for their respective shares of the oil and gas produced from the wells drilled under this Agreement in accordance with sub-section (c) of Section 11.

10.

Operator’s Insurance; Subcontractors’ Insurance; Operator’s Liability.

	(a)		Operator’s Insurance.Operator shall obtain and maintain at its own expense so long as it is Operator under this Agreement all required Workmen’s Compensation Insurance and comprehensive general public liability insurance in amounts and coverage not less than $1,000,000 per person per occurrence for personal injury or death and $1,000,000 for property damage per occurrence, which shall include coverage for blow-outs, and total liability coverage of not less than $10,000,000.

			Subject to the above limits, the Operator’s general public liability insurance shall be in all respects comparable to that generally maintained in the industry with respect to services of the type to be rendered

and activities of the type to be conducted under this Agreement. Operator’s general public liability insurance shall, if permitted by Operator’s insurance carrier:

	(i)		name the Developer as an additional insured party; and

	(ii)		provide that at least thirty (30) days’ prior notice of cancellation and any other adverse material change in the policy shall be given to the Developer.

			However, the Developer shall reimburse Operator for the additional cost, if any, of including it as an additional insured party under the Operator’s insurance.

			Current copies of all policies or certificates of the Operator’s insurance coverage shall be delivered to the Developer on request. It is understood and agreed that Operator’s insurance coverage may not adequately protect the interests of the Developer and that the Developer shall carry at its expense the excess or additional general public liability, property damage, and other insurance, if any, as the Developer deems appropriate.

	(b)		Subcontractors’ Insurance.Operator shall require all of its subcontractors to carry all required Workmen’s Compensation Insurance and to maintain such other insurance, if any, as Operator in its discretion may require.

	(c)		Operator’s Liability.Operator’s liability to the Developer as Operator under this Agreement shall be limited to, and Operator shall indemnify the Developer and hold it harmless from, claims, penalties, liabilities, obligations, charges, losses, costs, damages, or expenses (including but not limited to reasonable attorneys’ fees) relating to, caused by or arising out of:

	(i)		the noncompliance with or violation by Operator, its employees, agents, or subcontractors of any local, state or federal law, statute, regulation, or ordinance;

	(ii)		the negligence or misconduct of Operator, its employees, agents or subcontractors; or

	(iii)		the breach of or failure to comply with any provisions of this Agreement.

11.

Internal Revenue Code Election; Relationship of Parties; Right to Take Production in Kind.

	(a)		Internal Revenue Code Election.With respect to this Agreement, each of the parties elects under Section 761(a) of the Internal Revenue Code of 1986, as amended, to be excluded from the provisions of Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986, as amended. If the income tax laws of the state or states in which the property covered by this Agreement is located contain, or may subsequently contain, a similar election, each of the parties agrees that the election shall be exercised.

			Beginning with the first taxable year of operations under this Agreement, each party agrees that the deemed election provided by Section 1.761-2(b)(2)(ii) of the Regulations under the Internal Revenue Code of 1986, as amended, will apply; and no party will file an application under Section 1.761-2 (b)(3)(i) of the Regulations to revoke the election. Each party agrees to execute the documents and make the filings with the appropriate governmental authorities as may be necessary to effect the election.

	(b)		Relationship of Parties.It is not the intention of the parties to create, nor shall this Agreement be construed as creating, a mining or other partnership or association or to render the parties liable as partners or joint venturers for any purpose. Operator shall be deemed to be an independent contractor and shall perform its obligations as set forth in this Agreement.

	(c)		Right to Take Production in Kind.Subject to the provisions of Section 8 above, the Developer shall have the exclusive right to sell or dispose of its proportionate share of all oil and gas produced from the wells to be drilled under this Agreement, exclusive of production:

(i)

that may be used in development and producing operations;

	(ii)		unavoidably lost; and

	(iii)		used to fulfill any free gas obligations under the terms of the applicable Lease or Leases.

			Operator shall not have any right to sell or otherwise dispose of the oil and gas. The Developer shall have the exclusive right to execute all contracts relating to the sale or disposition of its proportionate share of the production from the wells drilled under this Agreement.

			Developer shall have no interest in any gas supply agreements of Operator, except the right to receive Developer’s share of the proceeds received from the sale of any gas or oil from wells developed under this Agreement. The Developer agrees to designate Operator or Operator’s designated bank agent as the Developer’s collection agent in any contracts. On request, Operator shall assist Developer in arranging the sale or disposition of Developer’s oil and gas under this Agreement and shall promptly provide the Developer with all relevant information that comes to Operator’s attention regarding opportunities for selling production.

			If Developer fails to take in kind or separately dispose of its proportionate share of the oil and gas produced under this Agreement, then Operator shall have the right, subject to the revocation at will by the Developer, but not the obligation, to purchase the oil and gas or sell it to others at any time and from time to time, for the account of the Developer at the best price obtainable in the area for the production. Notwithstanding, Operator shall have no liability to Developer should Operator fail to market the production.

			Any such purchase or sale by Operator shall be subject always to the right of the Developer to exercise at any time its right to take in-kind, or separately dispose of, its share of oil and gas not previously delivered to a purchaser. Any purchase or sale by Operator of the Developer’s share of oil and gas under this Agreement shall be only for reasonable periods of time as are consistent with the minimum needs of the oil and gas industry under the particular circumstances, but in no event for a period in excess of one (1) year.

12.

Effect of Force Majeure; Definition of Force Majeure; Limitation.

	(a)		Effect of Force Majeure.If Operator is rendered unable, wholly or in part, by force majeure (as defined below) to carry out any of its obligations under this Agreement, including but not limited to beginning the drilling of one or more wells by the applicable times set forth in Section 2(b), or any Addendum to this Agreement, the obligations of the Operator, so far as it is affected by the force majeure, shall be suspended during but no longer than, the continuance of the force majeure. The Operator shall give to the Developer prompt written notice of the force majeure with reasonably full particulars concerning it. Operator shall use all reasonable diligence to remove the force majeure as quickly as possible to the extent the same is within its reasonable control.

	(b)		Definition of Force Majeure.The term “force majeure” shall mean an act of God, strike, lockout, or other industrial disturbance, act of the public enemy, war, terrorist acts, blockade, public riot, lightning, fire, storm, flood, explosion, governmental restraint, unavailability of drilling rigs, equipment or materials, plant shut-downs, curtailments by oil and gas purchasers and any other causes whether of the kind specifically enumerated above or otherwise, which directly preclude Operator’s performance under this Agreement and is not reasonably within the control of the Operator including, but not limited to, the inability of Operator to begin the drilling of the wells subject to this Agreement by the applicable times set forth in Section 2(b) or in any Addendum to this Agreement due to decisions of third-party operators to delay drilling the wells, poor weather conditions, inability to obtain drilling permits, access right to the drilling site or title problems.

	(c)		Limitation.The requirement that any force majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes, lockouts, or other labor difficulty affecting the Operator contrary to its wishes. The method of handling these difficulties shall be entirely within the discretion of the Operator.

13.		Term.

		This Agreement shall become effective when executed by Operator and the Developer. Except as provided in sub-section (c) of Section 3, this Agreement shall continue and remain in full force and effect for the productive lives of each well being operated under this Agreement.

14.

Governing Law; Invalidity.

	(a)		Governing Law.This Agreement shall be governed by, construed and interpreted in accordance with the laws of the Commonwealth of Pennsylvania, excluding its conflict of law provisions.

	(b)		Invalidity.The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions of this Agreement, and this Agreement shall be construed in all respects as if the invalid or unenforceable provision were omitted.

15.

Integration; Written Amendment.

	(a)		Integration.This Agreement, including the Exhibits to this Agreement, constitutes and represents the entire understanding and agreement of the parties with respect to the subject matter of this Agreement and supersedes all prior negotiations, understandings, agreements, and representations relating to the subject matter of this Agreement.

	(b)		Written Amendment.No change, waiver, modification, or amendment of this Agreement shall be binding or of any effect unless in writing duly signed by the party against which the change, waiver, modification, or amendment is sought to be enforced.

16.		Waiver of Default or Breach.

		No waiver by any party to any default of or breach by any other party under this Agreement shall operate as a waiver of any future default or breach, whether of like or different character or nature.

17.		Notices.
