General Requirements apply to all advertised bids; however, these may be superseded, whole or in part, by the SPECIAL
REQUIREMENTS/INSTRUCTIONS OR OTHER DATA CONTAINED HEREIN. Review the Table of Contents. Be sure your bid package is

In special circumstances, vendor may be required to allow duly authorized representatives of Harris County, the Harris County Hospital District or
the state and federal government access to contracts, books, documents, and records necessary to verify the nature and extent of the cost of services
provided by vendor.

When specifications are revised, the Harris County Purchasing Department will issue an addendum addressing the nature of the change. Offerors
must sign and include it in the returned bid package.

The successful offeror may not assign, sell or otherwise transfer this contract without written permission of Harris County Commissioners Court.

Harris County reserves the right to award this contract on the basis of LOWEST AND BEST OFFER in accordance with the laws of the State of
Texas, to waive any formality or irregularity, to make awards to more than one offeror, to reject any or all bids. In the event the lowest dollar offeror
meeting specifications is not awarded a contract, the offeror may appear before the Commissioners Court, Hospital District Board of Managers,
Community Supervision & Corrections Department Board, the Juvenile Board or other applicable governing body and present evidence concerning
his responsibility after officially notifying the Office of the Purchasing Agent of his intent to appear.

Fill out and return to the Harris County Purchasing Department ONE (1) complete bid form in an appropriately sized envelope or box. PACKAGE
MUST SHOW THE JOB NUMBER, DESCRIPTION AND BE MARKED “SEALED BID.” An authorized representative of the offeror should
sign the Bid Cover Sheet. The contract will be binding only when signed by Harris County, funds are certified by the County Auditor and or the
Hospital District, as applicable, and a Purchase Order issued.

Offerors must return all completed bids to the Harris County Purchasing Department reception desk at 1001 Preston Avenue, Suite 670, Houston,
Texas before 2:00 P.M. LOCAL TIME IN HOUSTON, TEXAS on the date specified. Late bids will not be accepted.

If this bid requires submission of bid guarantee and performance bond, there will be a separate page explaining those requirements. Bids submitted
without the required bid bond or cashier's checks are not acceptable.

Determination of colors of materials is a right reserved by the using department unless otherwise specified in the bid. Unspecified colors shall be
quoted as standard colors, NOT colors which require upcharges or special handling. Unspecified fabrics or vinyls should be construed as medium
grade. If offeror fails to get color/material approvals prior to delivery of merchandise, the using department may refuse to accept the items and
demand correct shipment without penalty, subject to other legal remedies.

Harris County Commissioners Court must award the contract and the County Judge or other person authorized by the Harris County Commissioners
Court must sign the contract before it becomes binding on Harris County or the offerors. Department heads are NOT authorized to sign agreements
for Harris County. Binding agreements shall remain in effect until all products and/or services covered by this purchase have been satisfactorily
delivered and accepted.

Renewals may be made ONLY by written agreement between Harris County and the offeror. Any price escalations are limited to those stated by the
offeror in the original bid.

If offeror obtained the bid specifications in digital format in order to prepare a response, the bid must be submitted in hard copy according to the
instructions contained in this bid package. If, in its bid response, offeror makes any changes whatsoever to the County's published bid specifications,
the County's bid specifications as published shall control. Furthermore, if an alteration of any kind to the County's published bid specifications is
only discovered after the contract is executed and is or is not being performed, the contract is subject to immediate cancellation.

                                                                                                                                          Page 3 of 28
Upon signing this bid document, an offeror offering to sell supplies, materials, services, or equipment to Harris County certifies that the offeror has
not violated the antitrust laws of this state codified in Texas Business and Commerce Code §15.01, et seq., as amended, or the federal antitrust laws,
and has not communicated directly or indirectly the bid made to any competitor or any other person engaged in such line of business. Any or all bids
may be rejected if the County believes that collusion exists among the offerors. Bids in which the prices are obviously unbalanced may be rejected.
If multiple bids are submitted by an offeror and after the bids are opened, one of the bids is withdrawn, the result will be that all of the bids submitted
by that offeror will be withdrawn; however, nothing herein prohibits a vendor from submitting multiple bids for different products or services.

Vendor affirmatively consents to the disclosure of its e-mail addresses that are provided to Harris County, the Harris County Flood Control District,
the Harris County Hospital District including its HMO, the Harris County Appraisal District, or any agency of Harris County. This consent is
intended to comply with the requirements of the Texas Public Information Act, Tex. Gov’t Code Ann. §522.137, as amended, and shall survive
termination of this agreement. This consent shall apply to e-mail addresses provided by Vendor, its employees, officers, and agents acting on
Vendor’s behalf and shall apply to any e-mail address provided in any form for any reason whether related to this bid/proposal or otherwise.

Evaluation shall be used as a determinant as to which bid items or services are the most efficient and/or most economical for the County. It shall be
based on all factors which have a bearing on price and performance of the items in the user environment. All bids are subject to tabulation by the
Harris County Purchasing Department and recommendation to the appropriate governing body. Compliance with all bid requirements, delivery and
needs of the using department are considerations in evaluating bids. Pricing is NOT the only criteria for making a recommendation. The Harris
County Purchasing Department reserves the right to contact any offeror, at any time, to clarify, verify or request information with regard to any bid.

A multi-year lease or lease/purchase arrangement (if requested by the Special Requirements/Instructions), or any contract continuing as a result of an
extension option, must include fiscal funding out. If, for any reason, funds are not appropriated to continue the lease or contract, said lease or
contract shall become null and void on the last day of the current appropriation of funds. After expiration of the lease, leased equipment shall be
removed by the offeror from the using department without penalty of any kind or form to Harris County. All charges and physical activity related to
delivery, installation, removal and redelivery shall be the responsibility of the offeror.

In the event of any conflict between the terms and provisions of these requirements and the specifications, the specifications shall govern. In the
event of any conflict of interpretation of any part of this overall document, Harris County's interpretation shall govern.

This bid solicitation is governed by the competitive bidding requirements of the County Purchasing Act, Texas Local Government Code, §262.021 et seq.,
as amended. Offerors shall comply with all applicable federal, state and local laws and regulations. Offeror is further advised that these requirements
shall be fully governed by the laws of the State of Texas and that Harris County may request and rely on advice, decisions and opinions of the Attorney
General of Texas and the County Attorney concerning any portion of these requirements.

Any contract entered into by the County that is to be paid from grant funds shall be limited to payment from the grant funding and the
vendor/provider understands that the County has not set aside any County funds for the payment of obligations under a grant contract. If grant
funding should become unavailable at any time for the continuation of services paid for by the grant, and further funding cannot be obtained for the
contract, then the sole recourse of the provider shall be to terminate any further services under the contract and the contract shall be null and void.

Offeror agrees to comply with the Standards for Privacy of Individually Identifiable Health Information of the Health Insurance Portability and
Accountability Act of 1996, PL 104-191, 45 CFR Parts 160-164, as amended, and the Texas Medical Records Privacy Act, Texas Health and Safety
Code Chapter 181, as amended, collectively referred to as "HIPAA", to the extent that the Offeror uses, discloses or has access to protected health
information as defined by HIPAA. Offeror may be required to enter a Business Associate Agreement pursuant to HIPAA.

Contractor, the successful offeror, shall indemnify and hold Harris County harmless from all claims for personal injury, death and/or property
damage resulting directly or indirectly from contractor's performance. Contractor shall procure and maintain, with respect to the subject matter of
this bid, appropriate insurance coverage including, as a minimum, public liability and property damage with adequate limits to cover contractor's
liability as may arise directly or indirectly from work performed under terms of this bid. Certification of such coverage must be provided to the
County upon request.

Harris County reserves the right to inspect any item(s) or service location for compliance with specifications and requirements and needs of the using
department. If an offeror cannot furnish a sample of a bid item, where applicable, for review, or fails to satisfactorily show an ability to perform, the
County can reject the bid as inadequate.

Offerors shall submit an original invoice on each purchase order or purchase release after each delivery, indicating the purchase order number.
Invoices must be itemized. Any invoice, which cannot be verified by the contract price and/or is otherwise incorrect, will be returned to the offeror
for correction. Under term contracts, when multiple deliveries and/or services are required, the offeror may invoice following each delivery and the
County will pay on invoice. Contracts providing for a monthly charge will be billed and paid on a monthly basis only. Prior to any and all payments
made for goods and/or services provided under this contract, the offeror should provide his Taxpayer Identification Number or social security
number as applicable. This information must be on file with the Harris County Auditor’s office. Failure to provide this information may result in a
delay in payment and/or back-up withholding as required by the Internal Revenue Service.

Maintenance required for equipment bid should be available in Harris County by a manufacturer-authorized maintenance facility. Costs for this
service shall be shown on the Pricing/Delivery Information form. If Harris County opts to include maintenance, it shall be so stated in the purchase
order and said cost will be included. Service will commence only upon expiration of applicable warranties and should be priced accordingly.

Under the "Hazardous Communication Act", commonly known as the "Texas Right To Know Act", an offeror must provide to the County with each
delivery, material safety data sheets which are applicable to hazardous substances defined in the Act. Failure of the offeror to furnish this
documentation will be cause to reject any bid applying thereto.

Specifications may reference name brands and model numbers. It is not the intent of Harris County to restrict these bids in such cases, but to
establish a desired quality level of merchandise or to meet a pre-established standard due to like existing items. Offerors may offer items of equal
stature and the burden of proof of such stature rests with offerors. Harris County shall act as sole judge in determining equality and acceptability of
products offered.

All products and/or services furnished as part of this contract must be compliant for the present year and forward. This applies to all computers
including hardware and software as well as all other commodities with date sensitive embedded chips.

An outside consultant or contractor is prohibited from submitting a bid for services on a Harris County project of which the consultant or contractor
was a designer or other previous contributor, or was an affiliate, subsidiary, joint venturer or was in any other manner associated by ownership to any
party that was a designer or other previous contributor. If such a consultant or contractor submits a prohibited bid, that bid shall be disqualified on
the basis of conflict of interest, no matter when the conflict is discovered by Harris County.

Prices for all goods and/or services shall be firm for the duration of this contract and shall be stated on the Pricing/Delivery Information form. Prices
shall be all inclusive: No price changes, additions, or subsequent qualifications will be honored during the course of the contract. All prices
must be written in ink or typewritten. Pricing on all transportation, freight, drayage and other charges are to be prepaid by the contractor and
included in the bid prices. If there are any additional charges of any kind, other than those mentioned above, specified or unspecified, offeror MUST
indicate the items required and attendant costs or forfeit the right to payment for such items. Where unit pricing and extended pricing differ, unit
pricing prevails.

The successful offeror shall not deliver products or provide services without a Harris County Purchase Order, signed by an authorized agent of the
Harris County Purchasing Department. The fastest, most reasonable delivery time shall be indicated by the offeror in the proper place on the
Pricing/Delivery Information form. Any special information concerning delivery should also be included, on a separate sheet, if necessary. All items
shall be shipped F.O.B. INSIDE DELIVERY unless otherwise stated in the specifications. This shall be understood to include bringing
merchandise to the appropriate room or place designated by the using department. Every tender or delivery of goods must fully comply with all
provisions of these requirements and the specifications including time, delivery and quality. Nonconformance shall constitute a breach which must
be rectified prior to expiration of the time for performance. Failure to rectify within the performance period will be considered cause to reject future
deliveries and cancellation of the contract by Harris County without prejudice to other remedies provided by law. Where delivery times are
critical, Harris County reserves the right to award accordingly.

Harris County encourages the use of products made of recycled materials and shall give preference in purchasing to products made of recycled
materials if the products meet applicable specifications as to quantity and quality. Harris County will be the sole judge in determining product
preference application.

If any section, subsection, paragraph, sentence, clause, phrase or word of these requirements or the specifications shall be held invalid, such holding
shall not affect the remaining portions of these requirements and the specifications and it is hereby declared that such remaining portions would have
been included in these requirements and the specifications as though the invalid portion had been omitted.

The apparent silence of specifications as to any detail, or the apparent omission from it of a detailed description concerning any point, shall be
regarded as meaning that only the best commercial practice is to prevail and that only material and workmanship of the finest quality are to be used.
All interpretations of specifications shall be made on the basis of this statement. The items furnished under this contract shall be new, unused of the
latest product in production to commercial trade and shall be of the highest quality as to materials used and workmanship. Manufacturer furnishing
these items shall be experienced in design and construction of such items and shall be an established supplier of the item bid.

Offerors are responsible for including all pertinent product data in the returned bid package. Literature, brochures, data sheets, specification
information, completed forms requested as part of the bid package and any other facts which may affect the evaluation and subsequent contract award
should be included. Materials such as legal documents and contractual agreements, which the offeror wishes to include as a condition of the bid,
must also be in the returned bid package. Failure to include all necessary and proper supplemental materials may be cause to reject the entire bid.

Harris County is exempt from all federal excise, state and local taxes unless otherwise stated in this document. Harris County claims exemption from
all sales and/or use taxes under Texas Tax Code §151.309, as amended. Texas Limited Sales Tax Exemption Certificates will be furnished upon
written request to the Harris County Purchasing Agent.

If the contract is intended to cover a specific time period, the term will be given in the specifications under SCOPE.

Harris County reserves the right to terminate the contract for default if offeror breaches any of the terms therein, including warranties of offeror or if
the offeror becomes insolvent or commits acts of bankruptcy. Such right of termination is in addition to and not in lieu of any other remedies which
Harris County may have in law or equity. Default may be construed as, but not limited to, failure to deliver the proper goods and/or services within
the proper amount of time, and/or to properly perform any and all services required to Harris County's satisfaction and/or to meet all other
obligations and requirements. Harris County may terminate the contract without cause upon thirty (30) days written notice.

Title and Risk of Loss of goods shall not pass to Harris County until Harris County actually receives and takes possession of the goods at the point or
points of delivery. Receiving times may vary with the using department. Generally, deliveries may be made between 8:30 a.m. and 4:00 p.m.,
Monday through Friday. Offerors are advised to consult the using department for instructions. The place of delivery shall be shown under the
"Special Requirements/Instructions" section of this bid package and/or on the Purchase Order as a "Deliver To:" address.

Offeror and offeror's insurance carrier waive any and all rights whatsoever with regard to subrogation against Harris County as an indirect party to
any suit arising out of personal or property damages resulting from offeror's performance under this agreement.

Offerors shall furnish all data pertinent to warranties or guarantees which may apply to items in the bid. Offerors may not limit or exclude any
implied warranties. Offeror warrants that product sold to the County shall conform to the standards established by the U.S. Department of Labor
under the Occupational Safety and Health Act of 1970. In the event product does not conform to OSHA Standards, where applicable, Harris County
may return the product for correction or replacement at the offeror's expense. If offeror fails to make the appropriate correction within a reasonable
time, Harris County may correct at the offeror's expense.

Pursuant to TX Local Government Code 262.0276, Harris County Commissioners Court has adopted a policy which requires that vendors’ taxes be
current as of the date bids/proposals are due. Bidders with delinquent taxes on the due date will not be eligible for award. Whether or not a vendor’s
taxes are delinque will be determined by an independent review of the Tax Office records. Vendors who believe a delinquency is reflected in error
must contact the Tax Office to correct any errors or discrepancies prior to submitting their bid in order to ensure that their bid will be considered. Tax
records are available online at the Tax Office website—www.hctax.net. Prior to submitting a bid, vendors are encouraged to visit the Tax Office
website, set up a portfolio of their accounts and make their own initial determination of the status of their tax accounts. Furthermore, if, during the
performance of this contract, a vendor’s taxes become delinquent, Harris County reserves the right to provide notice to the Auditor or Treasurer

        equipment or experience may be rejected by Harris County.

661.3   Intent. The coating design specified has been stipulated by means of carefully controlled
        formulations durability testing methods.        The intent of Harris County Public
        Infrastructure Department is to procure coatings which are identical in all essential
        respects to the standards of the Texas Department of Transportation (TxDOT); hereafter
        referred to as "Standards". Paints provided under this specification shall meet all
        applicable requirements of the Environmental Protection Agency.

        Specifications, codes and accepted practices not specifically listed in these specifications
        are not applicable.

        When required, the paint manufacturer shall supply Labor Form LSB-OOOS-4, "Material
        Safety Data Sheet."

661.4   Conformance of Finished Products. Coatings shall conform, on a weight basis, to the
        composition requirements of the standard formulae. No section variation from the
        standard formulae will be permitted except for replace of volatiles lost in processing, or
        those approved by the Engineer. The finished coatings shall conform with all
        requirements stipulated for each standard formulae, and shall equal a Wet Standard in
        characteristics such as color, drying, flow, settling, brush ability, can stability, hiding, etc.

        Film characteristics such as gloss, hardness, light permanency, adhesion, etc., shall also
        conform. When testing for such conformity, the coating shall be applied and tested under
        parallel conditions with the Wet Standard.

        The finished product shall be free of skins and foreign materials.

661.5   Mill Tests and Testing. All paint contractors shall be required to furnish to the County
        Engineer a copy of certified Mill test report for all paint to be furnished and delivered to

        contractor and/or supplier. The manufacturer shall be required to reimburse Harris
        County for the cost of storage and/or handling of paint failing to meet specification

                                                                                            Page 13 of 28
                                                                                         Attachment j.
                                                                                          Page 2 of 10

        Testing shall be in accordance with TxDOT requirements. Any questions should be
        addressed to the County Engineer.

        Raw materials and finished products which fail to meet any requirements of these
        specifications shall be subject to rejection. Final acceptance or rejection shall be based on
        results of tests on samples of raw materials and paint taken during production, and upon
        tests made on finished paints prior to delivery. Approval of materials, as a result of
        preliminary testing prior to manufacture into finished coatings, shall not be binding upon
        final approval or rejection. Because of the possibility of contamination and volatile
        losses, it shall be agreed that only the Wet Standard, currently in possession of Harris
        County or the licensed testing agencies, shall constitute standards for final comparison
        involving acceptance or rejection. The judgment of the County Engineer shall be final in
        all questions relative to conformance with the provisions of these specifications.

661.6   Manufacturing procedures, except when specified, shall be left to the discretion of the
        contractor. It is the responsibility of the manufacturer to ascertain that the raw materials
        and manufacturing procedures he proposes to use will produce a product meeting the
        specification requirements.

661.7   Shipment shall be made in suitable, strong, well sealed containers which not only meet
        specifications and Federal requirements, but are also sufficiently sturdy to withstand
        normal handling to which shipments are subjected in transit. FINISHED COATING
        STORAGE FOR A MINIMUM OF ONE YEAR. When the finished product is palletized
        for shipment, the labels shall be to the outside for easy identification. Once the finished
        product has been labeled properly, the label shall not be modified or changed in any
        manner without specific approval of the County Engineer.

        Containers shall be filled by weight based on the actual gallon weight of the paint at 77
        degrees F.

661.8   Raw Materials. The exact brands and types of raw materials used in the Wet Standard are
        listed for the purpose of facilitating the selection of parallel material equal not only in
        quality and composition but also in physical and chemical behavior after being used in the
        finished product. Since evaluation of paint containing questionable materials may require
        sixty days and since meeting delivery schedules is a responsibility of the paint
        manufacturer, he is reminded that he should schedule material procurement and paint
        production to permit him to meet delivery commitments. The final decision as to the
        equality of materials shall be made by Harris County. After Harris County has agreed to
        the brand names of raw materials proposed by the contractor, no substitutions will be
        allowed during the manufacture without prior agreement with the Engineer.

           “The contractor should be aware that it is his responsibility to select raw materials that
            not only meet the individual raw material specifications but will also produce coating
                                             conforming to the specific formulae requirements.”

                                                                                         Page 14 of 28
