1.2 INTERPRETATION OF CONTRACT DOCUMENTS 1.2.1 It is the intention of the parties that all the terms of the Subcontract are to be considered as complimentary. However, in the event that such an interpretation is not possible, the order of precedence of the documents forming this Subcontract shall be (1) modifications of any documents forming part of the Subcontract; (2) the Subcontract, including attached Exhibits (unless the Starling Richardson General Provisions or the Contract Documents impose a higher standard or greater requirement on the Subcontractor, in which case the Starling Richardson General Provisions or the Contract Documents shall govern); (3) the Starling Richardson General Provisions (unless the provisions of (2) apply), and (4) the Contract Documents (unless the provisions of (2) apply.) 1.2.2 In the event of a conflict between or among modifications, the later in date shall prevail; in the event of a conflict between or among the terms of the Subcontract, the higher standard or greater requirement for Subcontractor shall prevail. 1.2.3 Should inconsistencies or omissions appear in the Subcontract and/or the Contract Documents it shall be the duty of Subcontractor to timely notify Contractor in writing. Upon receipt of said notice Contractor shall instruct Subcontractor as to the measures to be taken, and Subcontractor shall comply with Contractor’s instructions. Nothing herein shall bar Subcontractor’s right, if any, to seek additional compensation if allowable under the Subcontract.

ARTICLE 2 SUBCONTRACTOR

2.1 SUBCONTRACTOR’S INVESTIGATIONS AND REPRESENTATIONS 2.1.1 Subcontractor represents that it is fully qualified to perform this Subcontract, and acknowledges that prior to the execution of this Subcontract it has (a) by its own independent investigation ascertained and fully evaluated (i) the Work required by this Subcontract, (ii) the conditions and difficulties involved in performing the Work, (iii) the obligations of this Subcontract and the Contract Documents, and (iv) the nature, locality and site of the Work; and (b) verified all information furnished by Contractor or others, satisfying itself as to the correctness and accuracy of that information. Any failure by Subcontractor to investigate independently and become fully informed will not relieve Subcontractor from its responsibilities hereunder. 2.1.2 Subcontractor represents that it is financially solvent and capable of performing all Work under this Subcontract. 2.2 TIME OF PERFORMANCE 2.2.1 Subcontractor will proceed with the Work in a prompt and diligent manner, in accordance with Contractor’s schedules, as reasonably amended from time to time. Subcontractor shall be liable to Contractor for failure to adhere to Contractor’s schedule, including amendments, even if such schedules differ from schedules set forth in the Contract Documents or the time of completion called for by the Contract Documents. TIME IS OF THE ESSENCE. In agreeing to perform the Work in accordance herewith, Subcontractor has taken into account and made allowance for delays which should be reasonably anticipated or foreseeable. 2.2.2 Subcontractor shall notify Contractor in writing of any objection to any schedule or amendment thereof, within forth-eight (48) hours after receipt of such schedule or amendment. The failure by Subcontractor to object to any schedule or amendment shall constitute acceptance. 2.2.3 If requested by Contractor, Subcontractor shall submit detailed schedules for performance of the Subcontract, in a form acceptable to Contractor, which shall comply with all scheduling requirements of the Contract Documents and of Paragraph 2.2.1 above. Contractor may from time to time, at its sole discretion, direct Subcontractor to make reasonable modifications and revisions in such schedules. 2.2.4 Subcontractor will coordinate its Work with the Work of Contractor, other subcontractors and the Owner’s other contractors, if any, so no delays or interference will occur in completion of any and/or part of all of the Project. 2.2.5 Provided that Contractor has not actively interfered with the Subcontractor's performance, causing a delay on the critical path of the project schedule, Subcontractor expressly agrees not to make, and hereby waives any claim for damages (including but not limited to those resulting from increased labor or material costs, disruption, inefficiency, loss of productivity, impacts, jobsite overhead, home overhead or extended general condition costs) on account of any delay, obstruction or hindrance for any cause whatsoever, whether or not foreseeable and whether or not anticipated, and agrees that the sole right and remedy for any such delays and impacts of any kind shall be an extension of time provided the requisite written notice of a claim for an extension of time has been met. Contractor, in its sole discretion, may nonetheless grant additional costs via a change order in conjunction with adjustments to the project schedule; however, such shall not constitute a blanket waiver of this provision, nor shall other provisions of this contract in any way be construed as conflicting with or creating an ambiguity in the interpretation of this no damage for delay clause.

Specifically, and not by limitation, the express warranty provided by Subcontractor and the lower-tier subcontractors will not limit, in any respect, the implied warranty at law of the Subcontractor for the entire Work, including a warranty for the quality of labor and materials and of good and workmanlike manner. 2.4 SUBCONTRACTOR’S LIABILITY 2.4.1 Subcontractor hereby assumes the entire responsibility and liability for all Work, supervision, labor and materials provided hereunder, whether or not erected in place, and for all plant, scaffolding, tools, equipment, supplies and other things provided by Subcontractor until final acceptance of the Work by the Owner, and shall at all times prosecute the Work in a good and workmanlike manner, with diligence and continuity; in the event of any loss, damage or destruction thereof from any cause, Subcontractor shall be liable therefor, and shall repair, rebuild and make good said loss, damage or destruction at Subcontractor’s cost, except to the extent of any recoveries or payments from Builders Risk or property insurance, if any, applicable to such loss, damage or destruction. 2.4.2 Contractor shall also be allowed to offset any sums owed to Subcontractor pursuant to Work performed under this Subcontract with any damages incurred by Contractor as a result of the failure of Subcontractor to perform on any other project for Contractor. 2.4.3 Subcontractor shall be liable to Contractor for all costs Contractor incurs or becomes responsible for as a result of Subcontractor’s failure to perform this Subcontract in accordance with its terms. Subcontractor’s failure to perform shall include the failure of its lower-tier subcontractors to perform. Subcontractor’s liability shall include but not be limited to (1) damages and other delay costs payable by Contractor to the Owner (including liquidated damages); (2) Contractor’s or its agents increased costs of performance, such as extended overhead and increased performance costs resulting from delays or improper Work; (3) warranty and rework costs; (4) liability to third parties; (5) excess reprocurement costs; (6) consultants’ fees; and (7) attorneys’ fees and related costs. 2.4.4 In the event that Subcontractor or any of its agents, employees, suppliers, or lower-tier subcontractors utilize any machinery, equipment, tools, scaffolding, hoists, lifts or similar items belonging to or under the control of Contractor, Subcontractor shall be liable to Contractor for any loss or damage (including personal injury or death) which may arise or result from such use, except where such loss or damage shall be due solely to the negligence of Contractor employees operating Contractor-owned or Contractor-leased equipment. 2.4.5 All amounts owed by Subcontractor to Contractor as a result of the liability provisions of this Subcontract shall be paid upon demand. 2.5 INDEMNIFICATION 2.5.1 To the fullest extent permitted by law, the Subcontractor is liable for and will defend, indemnify, hold harmless and reimburse Contractor, Owner and Architect, and each officer, agent and employee of the same, against: (i) all claims arising out of any breach of this Subcontract by the Subcontractor, or a breach of any agreement relating to the Work or any Work done by any of its lower-tier subcontractors, or any negligent act, gross negligence, error or omission by

-5-

Subcontractor or any of its lower-tier subcontractors, or any patent or copyright infringement arising out of the performance of this Subcontract by Subcontractor or any of its lower-tier subcontractors; (ii) all liabilities, claims and demands for personal injury (including death) or property damage (real, personal, tangible or intangible) including injury or death to Subcontractor’s employees, together with any resulting costs, legal fees and consulting fees, arising out of or caused by any act or omission of the Subcontractor or any of its lower-tier subcontractors, their agents or employees; (iii) all liens, or claims of rights to enforce liens, against the Project, Project Site or any other improvements erected on the Project Site arising out of any Work performed or to be performed or labor, services or materials furnished or to be furnished under this Subcontract; and (iv) all other costs, damage, expenses and liabilities (including all resulting costs, legal fees and consultant fees) for which Contractor is liable to Owner under its Agreement, or to any third party under agreements with those third parties who may be affected by construction of the Project on account of or in any way related to Subcontractor’s Work. THIS INDEMNIFICATION APPLIES EVEN THOUGH THE MATTER TO BE INDEMNIFIED IS THE RESULT OF THE CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF CONTRACTOR, OWNER AND/OR ARCHITECT OR THEIR EMPLOYEES, SERVANTS, AGENTS OR OTHER SUBCONTRACTORS. THOSE DAMAGES THAT RESULT FROM THE SOLE NEGLIGENCE OR INTENTIONAL TORT OF CONTRACTOR, OWNER AND ARCHITECT SHALL BE EXCLUDED FROM SUBCONTRACTOR'S DUTY OF INDEMNIFICATION. Contractor has a right to withhold from any payments due or to become due Subcontractor an amount which, in Contractor’s opinion is reasonable to protect Contractor from any claims or lawsuits subject to this indemnification paragraph. These rights are in addition to Contractor’s other legal and equitable rights. The indemnification obligation under this provision and this Subcontract, or any other indemnification obligation under any other subparagraph of this Subcontract, are not limited by a limitation on amount or type of damages, compensation or benefits payable by or for the Subcontractor, or any lower-tier subcontractor, under applicable Worker’s or Workmen’s Compensation Acts, Disability Benefit Acts, Employee Benefit Acts nor by any requirement for insurance, or the furnishing of insurance by Subcontractor or any lower-tier subcontractor, under this Subcontract. Subcontractor shall, however, maintain insurance with respect to this indemnification obligation. The indemnity obligations shall survive completion or termination of the subcontract. 2.6 PATENTS AND ROYALTIES

Except as otherwise provided by the Contract Documents, Subcontractor shall pay all royalties and license fees which may be due with respect to the Work. Subcontractor shall defend all suits or claims for infringement of any patent rights that may be brought against Contractor or the Owner arising out of its Work, and shall be liable to Contractor and the Owner for all loss, including all costs and expenses, on account thereof. 2.7 TAXES AND PERMITS 2.7.1 Except as otherwise provided by the Contract Documents, Subcontractor agrees to pay, comply with and hold Contractor harmless from and against the payment of all Federal, state and local contributions, taxes, duties or premiums arising out of the performance of this Subcontract, and all Sales, Use or other duties or taxes of whatever nature levied or assessed against the Owner, Contractor or Subcontractor arising out of this Subcontract, including any interest or penalties. Subcontractor waives any and all claims for additional compensation because of any new contributions, duties, taxes or premiums, or any increases therein, unless payment therefor is specifically provided for in the Contract Documents. 2.7.2 Subcontractor shall obtain and pay for all permits, licenses, fees and certificates of inspection necessary for the prosecution and completion of the Work. Subcontractor shall arrange for all necessary inspections and approvals by public officials. 2.8 SUPERVISION

Subcontractor and its lower-tier subcontractors (i) shall not employ anyone to perform Work whose employment is objected to by Contractor or the Owner, (ii) shall employ skilled and competent supervisory and subordinate personnel at the jobsite at all times who are familiar with their obligations under this Subcontract, the Contract Documents and Contractor’s schedule, are capable of communicating effectively with Contractor’s Project staff and who shall perform the Work with the highest degree of skill.

-6-

2.9 CLEANUP Subcontractor shall, on a daily basis, clean its Work and remove and deposit all debris resulting from or associated with its Work in a manner that will not impede either the progress of the Project or of other trades. Should Subcontractor fail to clean its Work within twenty-four (24) hours after receipt of written notice from Contractor, Contractor shall have the right to perform cleanup itself and charge Subcontractor the reasonable cost thereof, including an allocation of the cost of cleanup not identifiable to any source. Contractor may request composite crew clean up activities in which this Subcontractor will participate, if performing Work during the period of such request. 2.10 INTERFERENCE WITH WORK OF CONTRACTORS Neither Subcontractor nor any of its lower-tier subcontractors will directly or indirectly cause, or induce others to cause, any interference with the Work of any other contractor or Subcontractor on the jobsite. Subcontractor shall only employ workmen who will Work in harmony with those employed by the Contractor and other subcontractors. Should any workers performing Work covered by this Subcontract engage in a strike or other Work stoppage or cease to Work due to picketing or a labor dispute of any kind, said circumstance shall be deemed a failure to perform the Work and shall constitute a default by Subcontractor, subjecting it to the terms and conditions set forth in Article 9 herein. Furthermore, Subcontractor acknowledges that the project will be constructed, and Work performed, utilizing many other employers, Subcontractors, suppliers, and vendors providing supplies and materials, who may or may not be a party to, or signatory to, collective bargaining agreements or project labor agreements. If pickets are established by unions at the jobsite, Subcontractor agrees that its employees and those of its lower-tier subcontractors will either cross picket lines or enter the jobsite through a separate entrance established for such use. Failure of Subcontractor to man the job with a sufficient number of skilled workers during a labor dispute shall have no effect on Contractor's remedies under Article 9 of this Subcontract. Subcontractor agrees that Contractor is entitled to all remedies provided in Article 2.2, 2.4, and 9.1 of this Subcontract should Subcontractor delay the project as a result of a labor dispute of any nature. 2.11 ASSIGNMENT AND SUBCONTRACTING 2.11.1 Subcontractor shall not assign or transfer this Subcontract, or funds due hereunder, without the prior written consent of Subcontractor’s surety and Contractor. Lower-tier subcontracts are subject to the provisions of this Subcontract, and Subcontractor shall insert in Subcontractor’s subcontracts all provisions required by the Contract Documents or necessary to enable Subcontractor to comply with the terms hereof. Subcontracting by Subcontractor shall not abrogate any obligation of Subcontractor under this Subcontract. 2.11.2 Subcontractor shall, within thirty (30) days after award of this Subcontract and monthly thereafter, provide a detailed, itemized list of materials and equipment to be provided under this Subcontract along with the ultimate supplier of each material item and equipment, the supplier’s representative and phone number, and the current proposed delivery date of the material and equipment. Contractor reserves the right to review and/or approve Subcontractor’s subcontractor. Such approval will not be unreasonably withheld. 2.11.3 Subcontractor, by execution of this Subcontract, contingently assigns to Contractor all of Subcontractor’s subcontracts. The assignment of each of Subcontractor’s subcontracts shall take effect only upon both Subcontractor’s termination under either Article 9 or 10 and Contractor’s affirmative acceptance of the assignment of the specific subcontract by written notice to Subcontractor and Subcontractor’s subcontractor. Contractor shall have no liability to any of Subcontractor’s subcontractors unless and until Contractor affirmatively accepts the assignment as provided above. 2.12 APPROVALS 2.12.1 Subcontractor warrants and agrees that all requisite approvals from the Owner as to its eligibility to serve as a subcontractor, and that approvals of all materials and performance of the Work as required by the Contract documents, are obtainable. 2.12.2 Subcontractor shall deliver to Contractor copies of shop drawings, cuts, samples, material lists, and other submissions, including mock-ups and temporary structures, required by Contractor or the Contract Documents within sufficient time so as not to delay performance of the Project and within sufficient time for Contractor to submit the same within the time stated in the Contract Documents, whichever is earlier. Submissions shall be in strict accordance with the Contract Documents provided, however, that if Subcontractor wishes to propose a deviation from the Contract Documents, such deviation shall be clearly identified on the submission and accompanied by a letter describing in detail such deviation and the effect, if any, on Subcontractor’s Work and on the Work of Contractor or any other subcontractors on the Project, and the impact on the time of performance. Requested deviations will be allowed only in accordance with the Contract Documents and when specific written approval referencing the deviation is given to Subcontractor. No general approval granted by Contractor or the Owner shall relieve Subcontractor from complying with the Contract Documents.

-7-

2.12.3 Contractor’s review or approval of any shop drawings, cuts, samples, material lists and other submissions, including mock-ups or temporary structures, shall not to any extent, under any circumstances, (i) alter the requirements of the Contract Documents for quality, quantity, finish, dimension, design or configuration; (ii) constitute acceptance by Contractor of any method, material or equipment not ultimately acceptable to the Owner; or (iii) relieve Subcontractor from responsibility for errors of any sort therein or from the necessity of furnishing any Work required by the Contract Documents which may have been omitted therefrom. 2.13 INSPECTION AND ACCEPTANCE 2.13.1 Subcontractor shall provide appropriate facilities at all reasonable times for inspection, by Contractor or the Owner, of the Work and materials provided under this Subcontract, whether at the Project site or any place where such Work or materials may be in preparation, manufacture, storage or installation. Subcontractor shall promptly replace or correct any Work or materials which Contractor or the Owner shall reject as failing to conform to the requirements of this Subcontract. If Subcontractor does not do so within a reasonable time, Contractor shall have the right to do so and Subcontractor shall be liable to Contractor for the cost thereof. If, in the opinion of Contractor, it is not expedient to correct or replace all or any part of rejected Work or materials, then Contractor, at its option, may deduct from the payments due, or to become due, to Subcontractor such amount as in Contractor’s reasonable judgment will represent (i) the difference between the fair value of the rejected Work and materials and the value thereof if it complied with this Subcontract, or (ii) the cost of correction, whichever Contractor determines is more appropriate.

2.13.2 If rejection of Work is by the Owner, or by Contractor at the request of the Owner, Subcontractor’s remedy for wrongful rejection of Work pursuant to Paragraph 2.13.1 shall be limited to Contractor’s remedy under the Contract Documents. Contractor shall be liable for any increased direct cost caused by its wrongful rejection of Work only if the Owner was not involved in any such rejection. 2.13.3 The Work shall be accepted according to the terms of the Contract Documents. Unless otherwise agreed in writing, however, entrance and use by the Owner or Contractor, shall not constitute acceptance of the Work.

ARTICLE 3 CLAIMS AND DISPUTES

3.1 DEFINITION

A claim is a demand or assertion by one of the parties seeking, as a matter of right, adjustment or interpretation of Subcontract terms or payment of money, extension of time, or other relief with respect to the terms of the Subcontract. 3.2 TIME LIMIT AND MONETARY LIMITATION ON CLAIMS

(i) Claims by Subcontractor must be made within forty-eight (48) hours after Subcontractor first recognizes the condition giving rise to the claim. Claims must be made by written notice to Contractor containing a complete description of the claim and circumstances thereof.

(ii) To the extent and only to the extent that Contractor is liable for any delay damages for any active interference of

Subcontractor's Work, or to the extent an arbitrator, arbitration panel or court should determine that Subcontractor can recover delay damages against Contractor, notwithstanding the limitations above, the following standards will apply:

a. No indirect or consequential damages will be allowed; b. No recovery shall be based on a comparison of planned expenditures to total actual expenditures or on

estimated losses of labor efficiency, or on a comparison of planned man loading to actual man loading, or any other analysis that is used to show damages indirectly;

c. Damages are limited to extra costs specifically shown to have been directly caused by a proven wrong; d. The maximum daily limit on any recovery for delay shall be the amount originally estimated by the

subcontractor for job overhead costs divided by the total number of calendar days of contract time called for in the original contract;

e. No damages will be allowed for home office overhead or other home office charges or any Eichleay formula calculation; and,

f. No profit will be allowed on any damage claim.

-8-

3.3 CONTINUING CONTRACT PERFORMANCE

In the event of any dispute involving the Work, Subcontractor must proceed diligently with performance of its Work and must follow any decision by Contractor with respect to the dispute until final resolution. If Subcontractor makes a claim as provided herein, Subcontractor must continue with its Work without interruption, deficiency or delay. 3.4 ACCEPTANCE OF FINAL PAYMENT

Acceptance of final payment for the Work by the Subcontractor constitutes a waiver of any claims except those claims identified by the Subcontractor in writing at the time of final payment. 3.5 SETTLEMENT OF DISPUTES 3.5.1 In case of any dispute between Contractor and Subcontractor in any way relating to or arising from any act or omission of the Owner, the Architect, or involving the Contract Documents, Subcontractor agrees to be bound to Contractor to the same extent that Contractor is bound to the Owner by the terms of the Contract Documents, and by any and all preliminary and final decisions or determinations made thereunder by any party, board or court so authorized in the Contract Documents or by law, whether or not Subcontractor is a party to such proceedings. In case of such dispute, Subcontractor will comply with all provisions of the Contract Documents and allow a reasonable time for Contractor to analyze and forward to the Owner any required communications or documentation sufficiently in advance of any time limits set forth in the Contract Documents. Contractor may, at its option, (1) present to the Owner, in Contractor’s name, or (2) authorize Subcontractor to present to the Owner, in Contractor’s name, all of Subcontractor’s claims and answer the Owner’s claims involving Subcontractor’s Work. Contractor may further invoke on behalf of Subcontractor, or allow Subcontractor to invoke, those provisions in the Contract Documents for determining disputes. Nothing herein shall require Contractor to certify a claim under a contract when it cannot do so in good faith. If such dispute is prosecuted or defended by Contractor, Subcontractor at its own expense agrees to furnish all documents, statements, witnesses, and other information required by Contractor and to pay or reimburse Contractor for all costs incurred by Contractor in connection with the dispute, including attorneys’ fees. If Contractor exercises either of the options referenced above, Subcontractor agrees that it shall only recover against Contractor to the extent Contractor recovers funds from the Owner. 3.5.2 All other disputes between the parties shall be resolved by litigation, in a court of competent jurisdiction, except that Contractor may, at its sole option, require that any dispute be submitted to arbitration pursuant to the Construction Industry Rules of the American Arbitration Association except that for disputes equal or less than $100,000, a single arbitrator shall be appointed who will be an attorney with at least (10) years of experience in construction law, and for disputes in excess of $100,000, there shall be three (3) arbitrators with each having at least ten (10) years of experience on construction law. The election by Contractor shall be made no later than thirty (30) days following receipt of service of process of any such litigation from Subcontractor or, if the claim is asserted by Contractor, shall be made upon the filing of a demand for arbitration by Contractor. Notwithstanding the above, Contractor shall not be deemed to have waived any right it may have to arbitrate its dispute with Subcontractor by the filing of litigation against Subcontractor and its surety. In the event of arbitration solely between Contractor and Subcontractor, all rulings of law shall be appealable de novo. 3.5.3 If Contractor elects to arbitrate any such dispute with Subcontractor, Subcontractor consents to the joint arbitration of any dispute it might have with Contractor with the arbitration of any dispute Contractor might have with any other subcontractor of Contractor or with Owner or Architect, if Contractor should so elect. 3.5.4 In the event of litigation or arbitration of any dispute between Subcontractor and Contractor, the prevailing party shall be awarded attorneys’ fees, costs of court and such other damages as may be permitted by the Subcontract and applicable law. 3.5.5 IN THE EVENT LITIGATION IS AUTHORIZED AND BROUGHT FOR THE RESOLUTION OF ANY DISPUTE OR CLAIM ARISING FROM THE PROJECT, INCLUDING BUT NOT LIMITED TO THE OBLIGATIONS OR RESPONSIBILITIES OF THE PARTIES WITH REGARD TO THE PROJECT, AND PROVIDED THAT THE LITIGATION IS SOLELY BETWEEN CONTRACTOR AND SUBCONTRACTOR (OR WITH OTHER PARTIES WITH SIMILAR WAIVER PROVISIONS IN THEIR CONTRACTS), CONTRACTOR AND SUBCONTRACTOR DO HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT EACH PARTY MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY SUCH LITIGATION AND THE ISSUES TO BE TRIED THEREIN. IT IS THE INTENT OF THE PARTIES THAT IN ANY SUCH LITIGATION BETWEEN THE PARTIES, ALL ISSUES IN SUCH LITIGATION SHALL BE TRIED TO A JUDGE AND NOT A JURY.

ARTICLE 4 CHANGES IN THE WORK

4.1 Contractor may, at any time, unilaterally or by agreement with Subcontractor, without notice to any surety, make changes in the Work covered by this Subcontract. Any unilateral order or agreement under this Article 4 shall be in writing. Subcontractor shall perform the Work as changed without delay. 4.2 Subcontractor shall submit to Contractor any requests or claims for adjustment in the price, schedule or other provisions of the Subcontract for changes directed by the Owner, as a result of deficiencies or discrepancies in the Contract Documents, or for circumstances otherwise permitted by the Contract Documents. Said requests or claims shall be submitted in writing by Subcontractor in time to allow Contractor to comply with the applicable provisions of the Contract Documents. Subcontract adjustments shall be made only to the extent that Contractor is entitled to relief from or must grant relief to the Owner. Further, each Subcontract adjustment shall be equal only to Subcontractor’s allocable share of any adjustment in Contractor’s contract with the Owner. Subcontractor’s allocable share shall be determined by Contractor, after allowance of Contractor’s normal overhead and profit on any recovery and Contractor’s expense of recovery, by making a reasonable apportionment, if applicable, between Subcontractor, Contractor and other subcontractors or persons with interests in the adjustment. This paragraph shall also cover other equitable adjustments or other relief allowed by the Contract Documents. 4.3 Payment on account of pending changes made by the Owner shall be made only if and when Contractor receives such payment from the Owner for Subcontractor’s changed Work. Each payment to Subcontractor on account of pending change orders shall be equal to Subcontractor’s allocable share of Contractor’s payment from the Owner for the pending change as determined by Contractor. Amounts paid on account of pending changes are provisional and not an admission of liability and shall be repaid to Contractor on demand whenever Contractor determines there has been an overpayment. 4.4 For changes ordered by Contractor independent of the Owner or the Contract Documents, Subcontractor shall be entitled to equitable adjustment in the Subcontract price. If Subcontractor considers any action or inaction by Contractor other than a formal change order to be a change, it shall so notify Contractor in writing, within forty-eight (48) hours of said action or inaction and seek a confirmation from Contractor. Failure to comply with said confirmation procedure shall constitute a waiver of the right to compensation for the action or inaction. Change orders or charges of any kind, occurring between Contractor and Subcontractor independent of the Owner or the Contract Documents shall be performed and paid for on the basis of direct cost only, without any overhead, indirect expense or profit. 4.5 Subcontractor shall within seven (7) days of a Contractor request submit a reasonable price quotation for proposed changes. If Subcontractor does not do so and Contractor is required to submit a price quotation to the Owner which includes a proposed change to Subcontractor’s Work, Contractor shall use its best estimate of the proposed change as it affects the Subcontract in its quotation to the Owner, which estimate shall be the maximum equitable adjustment due to Subcontractor. 4.6 The payment of any incremental increase in the cost of bonds arising as a result of changes in the Work shall be the responsibility of Subcontractor and will be included as a part of Subcontractor’s price for proposed changes.

ARTICLE 5 PAYMENTS

5.1 SCHEDULE OF VALUES 5.1.1 Before the first application for payment, Subcontractor must submit to Contractor for its approval an itemized schedule of values (“Schedule of Values”) allocated to the various portions of the Work prepared in such form and supported by such data to substantiate its accuracy as Contractor may reasonably require and/or as required by the Contract Documents. 5.1.2 This schedule, unless objected to by Contractor, Owner or the Architect, will be used only as a basis of Subcontractor’s applications for payment. The form of the application for payment will be as directed by Contractor and/or as required by the Contract Documents together with applicable receipted bills and payroll sheets. 5.2 APPLICATION FOR PAYMENT 5.2.1 Subcontractor must submit to Contractor an itemized application for payment, notarized, if required by applicable law or requested by Owner, supported by such data substantiating the Subcontractor’s right to payment as Contractor, Owner or the Architect may require, including requisitions from subcontractors and sub-subcontractors.

-10-

5.2.2 If requested by Contractor, Subcontractor shall, as part of each request for partial payment other than the initial request, furnish claim releases and lien waivers with respect to all Work performed and materials supplied through the date of the immediately preceding request for partial payment. Prior to final payment, Subcontractor shall provide to Contractor a release of its liens and claims and all liens and claims of all persons furnishing labor and/or materials for the performance of this Subcontract, and satisfactory evidence that there are no other liens or claims whatsoever outstanding against the Work relating to this Subcontract. 5.2.3 If the Contract Documents allow partial payment for materials stored either off-site or on-site, such payments shall be made to Subcontractor in the amounts and under the standards set forth in the Contract Documents for off-site or on-site stored materials once such payments have been approved by Contractor and the Owner, but only after Contractor’s receipt of payment therefor from the Owner. 5.2.4 No partial payment shall be due Subcontractor unless and until Contractor receives payment from Owner and provided that the Work has been approved by Contractor and the Owner and provided that Subcontractor is in compliance with the terms of its Subcontract. Final payment shall not be due until Subcontractor’s Work has been completed and approved by the Owner, the entire Project is complete, all final payment prerequisites under the Contract Documents have been satisfied, satisfactory proof of payment of all amounts owed by Subcontractor in connection with this Subcontract has been provided and Contractor has been paid in full for the entire Project. Notwithstanding the above, Contractor may withhold from any partial or final payment to Subcontractor such amounts as may be allowed by the Subcontract in Paragraph 5.3. No certification of a progress payment and no partial nor final payment made to Subcontractor pursuant to this Subcontract shall constitute or imply acceptance of Work or materials. 5.2.5 WITH RESPECT TO ALL PROGRESS AND FINAL PAYMENTS, SUBCONTRACTOR ACKNOWLEDGES AND AGREES THAT IT SHALL BE PAID BY CONTRACTOR OUT OF FUNDS RECEIVED BY CONTRACTOR FROM THE OWNER, THAT CONTRACTOR'S RECEIPT OF PAYMENT FROM OWNER IS AN EXPRESS CONDITION PRECEDENT TO CONTRACTOR'S OBLIGATION TO MAKE ANY PAYMENT TO SUBCONTRACTOR UNDER THIS AGREEMENT AND THAT SUBCONTRACTOR IS NOT ENTITLED TO PAYMENT OF ANY SUMS UNDER THIS SUBCONTRACT UNTIL CONTRACTOR HAS BEEN PAID FOR SUCH WORK BY THE OWNER. SUBCONTRACTOR EXPRESSLY ASSUMES THE RISK OF INSOLVENCY OF THE OWNER. 5.2.6 If at any time any monies earned by or due to Contractor from the Owner are not paid in full, Contractor shall in its sole discretion apportion the nonpayment equitably and reduce payments otherwise due Subcontractor accordingly. Such reductions shall continue until Contractor is paid all monies due to it, provided however, if the withholdings do not relate to Subcontractor’s Work, Subcontractor shall be paid in full when Contractor’s right to recover from the Owner is finally determined or expires. Subcontractor acknowledges that this paragraph establishes a reasonable time for payment. 5.2.7 Contractor, after giving a three (3) day notice to Subcontractors, may pay all persons who have not been paid the monies due them in connection with the Subcontract, whether or not a lien or bond claim has or could be filed or perfected, unless Subcontractor, within three days of receipt of said notice, or such shorter period of time as Contractor finds necessary to meet its obligations to the Owner (i) demonstrates that such sums are not due and (ii) provides Contractor adequate security. Contractor, without prejudice to any other right it may have, may also issue a Joint Check to Subcontractor and any lower-tier subcontractor or supplier of Subcontractor and the delivery of said Joint Check to the lower-tier subcontractor or supplier shall constitute payment to Subcontractor. 5.2.8 All material and Work incorporated into the Project or for which partial payment has been made shall become the property of Contractor, or if the Contract Documents so provide, the property of the Owner; however, this provision shall not relieve Subcontractor from the sole responsibility and liability for all Work and materials for which payments have been made until final acceptance thereof by the Owner. 5.3 PAYMENTS WITHHELD 5.3.1 Notwithstanding any provision of the Subcontract to the contrary, Contractor is not obligated to make any payment to Subcontractor under the Subcontract if any one or more of the following conditions exists:

(a) CONTRACTOR HAS NOT BEEN PAID BY THE OWNER FOR ANY REASON OTHER THAN THE DEFAULT BY CONTRACTOR;

(b) If any part of such payment is attributable to Work which is not performed in accordance with the Contract

Documents; provided, however, payment will be made for the portions of the Work which have been performed in accordance with the Contract Documents;

(c) Subcontractor or any subcontractor has failed to make payments promptly to any lower-tier subcontractor, as

applicable, or to pay for material or labor used in the Work for which Subcontractor has received payment;

-11-

(d) Subcontractor has failed to provide the revised Schedule of Values with the Application for Payment;

(e) Subcontractor has suspended the Work other than as authorized by Owner or the Contractor;

(f) Subcontractor has filed a voluntary petition for protection or relief under -- or a petition has been filed placing

Subcontractor under -- the protection of the Bankruptcy laws of the United States and Subcontractor has not (1) notified Contractor that Subcontractor has the necessary capacity and resources to finish the Work and honor the Subcontract and will dismiss such petition and removed itself from bankruptcy protection within 90 days of the filing or (2) affirmed and had the bankruptcy court approve its obligations under this Subcontract to Contractor and evidence Subcontractor’s ability to perform this Subcontract to Contractor’s reasonable satisfaction;

(g) Subcontractor has failed to provide or maintain required insurance and bonds;

(h) Contractor determines, in good faith, that Subcontractor has breached any other agreement it might have with

Contractor on any other project; or (i) Contractor determines, in good faith, that the Subcontractor's financial condition has become, in the

Contractor's opinion, unsatisfactory so as to allow for the completion of the Work in the Subcontract. 5.3.2 In the event any of the conditions as outlined in Paragraph 5.3.1 exists, Contractor may withhold such funds as may be reasonably necessary to protect it from liability or compensate it for its damages; provided, however, that the exercising of the right of withholding by Contractor shall not be conclusive with respect to any liability of Subcontractor to Contractor.

ARTICLE 6 PROTECTION OF PERSONS AND PROPERTY

6.1 SAFETY OF PERSONS AND PROPERTY 6.1.1 The Subcontractor must take all reasonable precautions for the safety of, and must provide all reasonable protection to prevent damage, injury or loss to:

Subcontractor shall designate an employee to be responsible for compliance with all federal, state, and local safety and health regulations and all safety policies and requirements imposed by Contractor or the Owner. Unless the Subcontractor designates otherwise, the responsible employee shall be the Subcontractor’s job site supervisor. Subcontractor shall be liable to Contractor for any additional costs including fines, which Contractor incurs as a result of Subcontractor’s failure to operate safely. Contractor may conduct safety inspections from time to time. Such inspections shall not relieve Subcontractor from its obligations to adhere to safety requirements nor shall such inspections create any liability to Contractor.

Each bond must be issued in a form (refer to Exhibit “B”) and by a surety acceptable to Contractor, must be submitted to Contractor for approval as to form, must name Contractor as obligee and each must be in an amount equal to at least 100% of the Subcontract amount (as the same may be adjusted from time to time pursuant to the Contract), unless a greater amount is required by applicable law, in which case such greater amount will control. The Subcontractor must deliver the approved and executed bonds to Contractor upon execution of this Subcontract. In the event the surety which provided bonding becomes insolvent or fails during the term of the Subcontract, Subcontractor shall immediately replace, at its expense, the bonds with valid bonds from a new surety meeting the above requirements. Failure of Subcontractor to replace bonds would be a failure subject to the conditions defined in Article 9.1. 8.1.2 The payment bond must be issued in a form consistent with and as may be required by all applicable laws for the state in which the Project is located, such that, to the fullest extent possible at law, no liens can attach to the Project and all mechanics or materialmen’s liens filed in connection with the Work or the Project will attach only to the bonds.

-14-

8.1.3 Notwithstanding the above, and in the event that liens are filed by anyone in relation to the labor performed and/or material furnished pursuant to this Subcontract, Subcontractor agrees to have the same discharge by posting a bond with the appropriate authorities, or otherwise, within three days of notice. In the event such lien is not so discharged, Contractor may discharge the lien itself and hold Subcontractor responsible for all costs and obligations incurred. 8.1.4 If Subcontractor is not required to furnish bonds, or if Contractor desires Subcontractor to provide additional bond coverage, Contractor may, at any time, and upon written request, instruct Subcontractor to provide, and Subcontractor shall so provide within ten (10) days, performance and payment bonds as provided in this Article 8. In this event, Contractor will reimburse Subcontractor for reasonable bond premiums.

ARTICLE 9 TERMINATION

In case of termination for default, Subcontractor shall not be entitled to receive any further payment until the Work shall be fully completed and accepted by the Owner and payment in full made by the Owner. At such time, if the unpaid balance of the price to be paid shall exceed the expense incurred by Contractor, including overhead and profit, such excess shall be paid by Contractor to Subcontractor. If such amount shall exceed such unpaid balance, the Subcontractor shall pay Contractor the difference on demand. 9.1.3 If Contractor wrongfully exercises its option under Paragraph 9.1.1(i) that action shall be treated as a deductive change. If Contractor wrongfully exercises its option under Paragraph 9.1.1(ii) that termination for default shall be considered a termination for Contractor’s convenience and Subcontractor shall be entitled to the applicable compensation provided in Article 10, Subcontractor’s remedies under this Paragraph 9.1.3 shall be exclusive. Nothing herein shall bar withholdings by Contractor permitted by other provisions of this Subcontract.

ARTICLE 10 TERMINATION FOR CONVENIENCE

Contractor shall have the right to terminate for convenience Subcontractor’s performance of all or any part of the Work by

providing Subcontractor with a written notice of termination for convenience, to be effective upon receipt by Subcontractor.
