be collected for the use of water, water connections, power,

electric energy, or other services, provided, that the State of

Oklahoma does hereby pledge to and agree with the purchasers and

successive holders of the bonds issued hereunder that the state will

not limit or alter the power hereby vested in the district to

establish and collect such fees and charges as will produce revenues

sufficient to pay the items specified in subparagraphs (a), (b),

(c), (d) and (e) of this section, or in any way to impair the rights

or remedies of the holders of the bonds, or of any person in their

behalf, until the bonds, together with the interest thereon, with

interest on unpaid installments of interest and all costs and

expenses in connection with any action or proceedings by or on

behalf of the bondholders and all other obligations of the district

in connection with such bonds are fully met and discharged.
