2. DEFICIENCIES. All aspects in which the Facilities fail to satisfy the O&M Plan shall be noted

3. OWNER CORRECTIONS. All Deficiencies shall be corrected at Owner's expense within thirty
(30) days after completion of the inspection. If more than 30 days is reasonably needed to correct a Deficiency,
Owner shall have a reasonable period to correct the Deficiency so long as the correction is commenced within
the 30-day period and is diligently prosecuted to completion.
4. CITY INSPECTIONS. Owner grants City the right to inspect the Facilities. City will endeavor
to give ten(10) days prior written notice to Owner, except that no notice shall be required in case of an
emergency. City shall determine whether Deficiencies need to be corrected. Owner(at the address provided at
the end of this Agreement, or such other address as Owner may designate in writing to City)will be notified in
writing through the US Mail of the Deficiencies and shall make corrections within 30 days of the date of the
notice.
5. CITY CORRECTIONS. If correction of all Owner or City identified Deficiencies is not

corrected. City(i) shall have access to the Facilities for the purpose of correcting such Deficiencies and(ii) shall
bill Owner for all costs reasonably incurred by City for work performed to correct the Deficiencies(City
Correction Costs) following Owner's failure to correct any Deficiencies in the Facilities. Owner shall pay City
the City Correction Costs within thirty(30) days of the date of the invoice. Owner understands that this is a debt
owing to City. In addition, Owner agrees that upon non-payment, City Correction Costs shall be secured by a
lien on the Property for the City Correction Cost amount plus interest and penalties.
6. EMERGENCY MEASURES. If at any time City reasonably determines that the Facilities create
any imminent threat to public health, safety or welfare, City may immediately and without prior notice to
Owner take measures reasonably designed to remedy the threat. City shall provide notice of the threat and the
measures taken to Owner as soon as reasonably practicable, and if such imminent threat arose from a
Deficiency with the Facilities, charge Owner for the cost of these corrective measures as provided in Paragraph
5.
7. FORCE AND EFFECT. This Agreement shall constitute an equitable servitude or covenant
running with the land and shall bind all owners of the Property present and future, and their heirs, successors
and assigns.
8. AMENDMENTS. The terms of this Agreement may be amended only by mutual agreement of
the parties. Any amendments shall be in writing, shall refer specifically to this Agreement, and shall be valid
only when executed by the owners of the Property, City and recorded in the Official Records of the county
where the Property is located.
9. PREVAILING PARTY. In any action brought by either party to enforce the terms of this
Agreement, the prevailing party shall be entitled to recover all costs, including reasonable attorney's fees as may
be determined by the court having jurisdiction, including any appeal.
10. SEVERABILITY. The invalidity of any section, clause, sentence, or provision of this
Agreement shall not affect the validity of any other part of this Agreement, which can be given effect without
such invalid part or parts.
IN WITNESS WHEREOF, Owner and City have signed this Agreement.
