 As of the date of this Annual Report on Form 10-K,
CenterPoint Energy Transition Bond Company IV, LLC (the "Issuing Entity") has five managers. For as long as necessary under
applicable Rating Agency criteria (as such term is defined in the Issuing Entity's Amended and Restated Limited Liability Company
Agreement (the "LLC Agreement")) in order to maintain a rating of "AAA" (or the equivalent thereof) for the Issuing
Entity's Series 2012 Senior Secured Transition Bonds, the Issuing Entity shall have at least two individuals who are Independent
Managers (as such term is defined in the LLC Agreement). In the event that two Independent Managers are not necessary under applicable
Rating Agency criteria in order to maintain such a rating, the Issuing Entity shall have at least one individual who is an Independent
Manager. Currently, Messrs. Angelo and O'Connor serve as the Independent Managers of the Issuing Entity.

 Independent Manager is defined in the LLC Agreement
as a manager of the Issuing Entity who is not, and within the previous five years was not (except solely by virtue of such Person's
serving as, or affiliation with any other Person serving as, a special member or an independent director or manager, as applicable, of
CenterPoint Energy Houston Electric, LLC ("Houston Electric"), the Issuing Entity or any bankruptcy remote special purpose
entity that is an Affiliate of Houston Electric or the Issuing Entity), (i) a stockholder, member, partner, director, officer, employee,
Affiliate, customer, supplier, creditor or independent contractor of, or any Person that has received any benefit in any form whatsoever
from (other than in such Manager's capacity as a ratepayer or customer of Houston Electric in the ordinary course of business),
or any Person that has provided any service in any form whatsoever to, or any major creditor (or any Affiliate of any major creditor)
of, the Issuing Entity, Houston Electric or any of their Affiliates, or (ii) any Person owning beneficially, directly or indirectly,
any outstanding shares of common stock, any limited liability company interests or any partnership interests, as applicable, of the Issuing
Entity, Houston Electric, or any of their Affiliates, or of any major creditor (or any Affiliate of any major creditor) of any of the
foregoing, or a stockholder, member, partner, director, officer, employee, Affiliate, customer, supplier, creditor or independent contractor
of, or any Person that has received any benefit in any form whatever from (other than in such Person's capacity as a ratepayer or
customer of Houston Electric in the ordinary course of business), or any Person that has provided any service in any form whatever to,
such beneficial owner or any of such beneficial owner's Affiliates, or (iii) a member of the immediate family of any person
described above; provided that the indirect or beneficial ownership of stock through a mutual fund or similar diversified investment vehicle
with respect to which the owner does not have discretion or control over the investments held by such diversified investment vehicle shall
not preclude such owner from being an Independent Manager. For purposes of this definition, "major creditor" shall mean a
natural person or business entity to which the Issuing Entity, Houston Electric or any of their Affiliates has outstanding indebtedness
for borrowed money or credit on open account in a sum sufficiently large as would reasonably be expected to influence the judgment of
the proposed Independent Manager adversely to the interests of the Issuing Entity when the interests of that Person are adverse to those
of the Issuing Entity. Capitalized terms used in this paragraph have the meanings assigned to them in the LLC Agreement.
