Section 3.02. Issuance of Bonds; Application of Proceeds. To provide funds for the purpose of refunding the Refunded Bonds, the Issuer will issue, sell and deliver the Bonds.

Upon the deposit with the Refunded Bonds Trustee of adequate funds, or U.S. Government Obligations (as defined in the Refunded Bonds Indenture) which would produce adequate funds, for the payment of all Bond Service Charges (as defined in the Refunded Bonds Indenture) due on the Refunded Bonds on the date of their redemption and provided the other provisions of Article IX of the Refunded Bonds Indenture have been met, the Company shall be permitted to seek a release of the lien of any and all documents providing for the payment of the Refunded Bonds, including particularly the Refunded Bonds Indenture and the related Loan Agreement, and may seek repayment of any unrequired funds on deposit in the Clearing Fund, pursuant to Section 5.07 of the Indenture.

Section 3.03. Company Required to Provide Additional Moneys in Event Moneys Insufficient to Redeem Refunded Bonds.

Each of the Issuer and the Company hereby covenants that it will restrict any investment and reinvestment and the use of the proceeds of the Bonds in such manner and to such extent, if any, as may be necessary so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code.

The Company shall provide the Issuer with a certificate of an appropriate officer, employee or agent of or consultant to the Company for inclusion in the transcript of proceedings for the Bonds, setting forth the reasonable expectations of the Company on the date of delivery of and payment for the Bonds regarding the amount and use of the proceeds of the Bonds and the facts, estimates and circumstances on which those expectations are based.

Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to indemnify or hold harmless the Issuer, Allegheny County or their respective members, officers, employees and agents for their gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) or the Trustee or its officers, employees and agents for their negligence or willful misconduct ..

EVENTS OF DEFAULT AND REMEDIES

Section 7.01. Events of Default. Each of the following shall be an Event of Default:

(a)               The Company shall fail to pay the amounts required to be paid under Section 4.01 or 4.02 on the date specified therein.

(b)               Failure by the Company to observe and perform any covenant, condition or agreement on its part to be observed or performed under this Agreement, other than as referred to in Section 7.01(a), (other than certain representations, warranties and covenants regarding various matters relating to the tax status of the interest on the Bonds) for a period of 60 days after written notice specifying such failure and requesting that it be remedied shall have been given to the Company by the Issuer or the Trustee, unless the Issuer and the Trustee shall agree in writing to an extension of such time prior to its expiration; provided, however, if the failure stated in the notice cannot be corrected within the applicable period, it shall not constitute an Event of Default if corrective action is instituted by the Company within the applicable period and is being diligently pursued until the default is corrected.

(c)               The dissolution or liquidation of the Company or the voluntary initiation by the Company of any proceeding under any federal or state law relating to bankruptcy, insolvency, arrangement, reorganization, readjustment of debt or any other form of debtor relief, or the initiation against the Company of any such proceeding which shall remain undismissed for 60 days, or failure by the Company to promptly have discharged any execution, garnishment or attachment of such consequence as would materially impair the ability of the Company to carry on its operations, or assignment by the Company for the benefit of creditors, or the entry by the Company into an agreement of composition with creditors or the failure generally by the Company to pay its debts as they become due.

(d)               The occurrence of an Event of Default as defined in the Indenture.

Any declaration of default under subparagraph (c) and the exercise of remedies upon any such declaration will be subject to any applicable limitations of federal bankruptcy law affecting or precluding that declaration or exercise during the pendency of or immediately following any bankruptcy, liquidation or reorganization proceedings.

Section 7.02. Remedies on Default. Whenever an Event of Default shall have happened and be existing, any one or more of the following remedial steps may be taken:

(a)               if acceleration of the principal amount of the Bonds has been declared pursuant to Section 7.03 of the Indenture, the Issuer or the Trustee shall declare all Installment Payments to be immediately due and payable, whereupon the same shall become immediately due and payable; or

(b)               the Issuer or the Trustee may pursue all remedies now or hereafter existing at law or in equity to collect all amounts then due and thereafter to become due under this Agreement or to enforce the performance and observance of any other obligation or agreement of the Company under those instruments.

Notwithstanding the foregoing, the Trustee shall not be obligated to take any step that in its reasonable opinion will or might cause it to expend time or money or otherwise incur liability unless and until a satisfactory indemnity bond has been furnished to the Trustee at no cost or expense to it. Any amounts collected pursuant to action taken under this Section (except for amounts payable directly to the Issuer or the Trustee pursuant to Section 3.05, 4.02, 5.02 or 7.04) shall be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the Outstanding Bonds have been paid and discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 9.01 of the Indenture for transfers of remaining amounts in the Bond Fund.

The provisions of this Section are subject to the further limitation that the rescission by the Trustee of its declaration that all of the Bonds are immediately due and payable also shall constitute an annulment of any corresponding declaration made pursuant to paragraph (a) of this Section and a waiver and rescission of the consequences of that declaration and of the Event of Default with respect to which that declaration has been made, provided that no such waiver or rescission shall extend to or affect any subsequent or other default or impair any right consequent thereon.

Section 7.03. No Remedy Exclusive. No remedy conferred upon or reserved to the Issuer or the Trustee by this Agreement is intended to be exclusive of any other available remedy or remedies, but each and every remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement, now or hereafter existing at law, in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair that right or power or shall be construed to be a waiver thereof, but any such right and power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Issuer or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than any notice required by law or for which express provision is made herein.

Section 7.04. Agreement to Pay Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee should incur expenses, including attorneys’ fees, in connection with the enforcement of this Agreement or the collection of sums due hereunder, the Company shall reimburse the Issuer and the Trustee, as applicable, for their reasonable and documented out-of-pocket expenses so incurred upon demand.

Section 7.05. No Waiver. No failure by the Issuer or the Trustee to insist upon the performance by the Company of any provision hereof shall constitute a waiver of their right to performance and no express waiver shall be deemed to apply to any other existing or subsequent right to remedy the failure by the Company to observe or comply with any provision hereof.

Section 7.06. Notice of Default. The Company shall notify a Responsible Officer of the Trustee immediately and in writing if it becomes aware of the occurrence of any Event of Default hereunder or of any fact, condition or event which, with the giving of notice or passage of time or both, would become an Event of Default.

SCHEDULE 1

NONDISCRIMINATION/SEXUAL HARASSMENT CLAUSE

During the term of the Loan Agreement (referred to herein as the “contract”), the Company, as contractor, agrees, and will require its subcontractors, if any, to agree as follows:

(1)       In the hiring of any employee(s) for the manufacture of supplies, performance of work, or any other activity required under the contract or any subcontract, the Company, each subcontractor, or any person acting on behalf of the Company or subcontractor shall not discriminate by reason of race, gender, creed, color, sexual orientation, gender identity or expression, or in violation of the Pennsylvania Human Relations Act (“PHRA”) and applicable federal laws, against any citizen of the Commonwealth of Pennsylvania (the “Commonwealth”) who is qualified and available to perform the work to which the employment relates.

(2)       Neither the Company nor any subcontractor nor any person on their behalf shall in any manner discriminate by reason of race, gender, creed, color, sexual orientation, gender identity or expression, or in violation of the PHRA and applicable federal laws, against or intimidate any employee involved in the manufacture of supplies, the performance of work, or any other activity required under the contract.

(3)       Neither the Company nor any subcontractor nor any person on their behalf shall in any manner discriminate by reason of race, gender, creed, color, sexual orientation, gender identity or expression, or in violation of the PHRA and applicable federal laws, in the provision of services under the contract.

(4)       Neither the Company nor any subcontractor nor any person on their behalf shall in any manner discriminate against employees by reason of participation in or decision to refrain from participating in labor activities protected under the Public Employee Relations Act, Pennsylvania Labor Relations Act or National Labor Relations Act, as applicable and to the extent determined by entities charged with such Acts’ enforcement, and shall comply with any provision of law establishing organizations as employees’ exclusive representatives.

(5)       The Company and each subcontractor shall establish and maintain a written nondiscrimination and sexual harassment policy and shall inform their employees in writing of the policy. The policy must contain a provision that sexual harassment will not be tolerated and employees who practice it will be disciplined. Posting this Nondiscrimination/Sexual Harassment Clause conspicuously in easily-accessible and well-lighted places customarily frequented by employees and at or near where the contracted services are performed shall satisfy this requirement for employees with an established work site.

(6)       The Company and each subcontractor shall not discriminate by reason of race, gender, creed, color, sexual orientation, gender identity or expression, or in violation of PHRA and applicable federal laws, against any subcontractor or supplier who is qualified to perform the work to which the contract relates.

(7)       The Company and each subcontractor represents that it is presently in compliance with and will maintain compliance with all applicable federal, state, and local laws, regulations and policies relating to nondiscrimination and sexual harassment. The Company and each subcontractor further represents that it has filed a Standard Form 100 Employer Information Report (“EEO-1”) with the U.S. Equal Employment Opportunity Commission (“EEOC”) and shall file an annual EEO-1 report with the EEOC as required for employers’ subject to Title VII of the Civil Rights Act of 1964, as amended, that have 100 or more employees and employers that have federal government contracts or first-tier subcontracts and have 50 or more employees. The Company and each subcontractor shall, upon request and within the time periods requested by the Commonwealth, furnish all necessary employment documents and records, including EEO-1 reports, and permit access to their books, records, and accounts by the contracting agency and the Bureau of Diversity, Inclusion and Small Business Opportunities for purpose of ascertaining compliance with provisions of this Nondiscrimination/Sexual Harassment Clause.

(8)       The Company shall include the provisions of this Nondiscrimination/Sexual Harassment Clause in every subcontract so that those provisions applicable to subcontractors will be binding upon each subcontractor.

(9)       The Company’s and each subcontractor’s obligations pursuant to these provisions are ongoing from and after the effective date of the contract through the termination date thereof. Accordingly, the Company and each subcontractor shall have an obligation to inform the Commonwealth if, at any time during the term of the contract, it becomes aware of any actions or occurrences that would result in violation of these provisions.

(10)       The Commonwealth may cancel or terminate the contract and all money due or to become due under the contract may be forfeited for a violation of the terms and conditions of this Nondiscrimination/Sexual Harassment Clause. In addition, the agency may proceed with debarment or suspension and may place the Company in the Company Responsibility File.
