Mr. R. Blake Young

Bellaire, TX 77401

Dear Blake:

     Set forth below are the terms of your employment with Dynegy Inc.
(hereinafter referred to as the "Company").

     1. Title and Duties

     Your title shall be Executive Vice President of Technology and
Administration. You will report to the President or Chief Executive Officer.
Your duties will include such lawful duties as may be delegated from time to
time by the President or Chief Executive Officer. You shall devote your full
time, energy and skill to the performance of your duties for the Company, and
will exercise due diligence and reasonable care in the performance of such
duties. You will be employed at the Company's headquarters in Houston, Texas.

     2. Term

     (a) Unless earlier terminated as provided for herein, the term of this
Agreement will be for two (2) years, beginning on the Effective Date and ending
on the second anniversary of the Effective Date (such period, and any extension
thereof pursuant to the next succeeding sentence, the "Term"). At the time the
Term would otherwise expire, the Term shall automatically be extended for an
additional one (1) year period unless either the Company or you provide written
notice not less than sixty (60) days prior to the date on which this Agreement
would otherwise be automatically extended that such party is electing not to so
extend the Term. The term "Effective Date" means September 16, 2002.

     (b) If your employment with Dynegy is terminated for "cause" or terminates
due to your voluntary resignation (other than pursuant to a voluntary
resignation resulting from a "constructive termination" as set forth in
Paragraph 2(d)), Dynegy shall have no further obligation to you except for the
payment of amounts due before the date of such termination. You further agree
that the benefits which you have received from the execution of this Agreement
through the date of such termination constitute sufficient consideration for
your obligations pursuant to Paragraph 4, notwithstanding the fact that the
Company has no further obligation to you except for the payment of amounts due
before the date of such termination.

     For purposes of this Agreement, you may be terminated for "cause" as a
result of (i) refusal to implement or adhere to lawful policies or lawful
directives of the Board of Directors or the President or Chief Executive
Officer; (ii) engaging in conduct which is materially injurious (monetarily or
otherwise) to the Company or any of its affiliates (including, without
limitation, misuse of the Company's or an affiliate's funds or other property);
(iii) misconduct or dishonesty directly related to the performance of your
duties for the Company or gross negligence in the


                                       1

<PAGE>

performance of your duties for the Company; (iv) conviction (or entering into a
plea bargain admitting criminal guilt) in any criminal proceeding involving a
felony or a crime of moral turpitude; (v) drug or alcohol abuse; (vi) continued
failure to perform your duties under this Agreement which is not cured within 10
days after written notice is provided to you by the Company; or (vii) any other
material breach of this Agreement by you which is not cured within 10 days after
written notice is provided to you by the Company.

     (c) If your employment is terminated during the Term by the Company without
cause or by you due to a resignation following "constructive termination" (as
defined below), you shall receive the severance pay and other benefits for which
you are eligible under the Dynegy Inc. Executive Severance Pay Plan (effective
November 1, 2001) (the "Plan") in lieu of the payments and benefits described in
Paragraph 3 hereof, plus a cash lump sum payment equal to any unpaid portion of
the Retention Bonuses described in Paragraph 3(h). In addition to any severance
pay and other benefits for which you are eligible under the Plan, you shall
receive (i) a lump sum amount equal to the value of the 401(k) Plan matching
contribution and Portable Retirement Plan benefit you otherwise would have
received through the end of the Term of this Agreement; and (ii) any employee
stock options granted to you prior to or during the term of this Agreement shall
become vested as of your employment termination date, and you shall have the
right to exercise any such vested options through the end of the Term of this
Agreement, but in no event later than the original term of the option.

     For purposes of this Agreement a "constructive termination" shall be deemed
to have occurred in the event that (i) your Base Salary as defined in Paragraph
3(a) is reduced; or (ii) the Company materially breaches this Agreement; or
(iii) your position is relocated outside of the Houston, Texas metropolitan
area. Any resignation by you as a result of assertion of a constructive
termination shall be communicated by delivery to the Chief Executive Officer of
the Company within thirty (30) days from the commencement of such constructive
termination by written notice setting forth the grounds therefore, during which
period the Company shall be entitled to cure or remedy the matters set forth in
such notice to your reasonable satisfaction. Unless you withdraw such notice
prior to the expiration of this thirty (30) day period, such resignation shall
take effect upon the expiration of thirty (30) days from the date of the
delivery of the notice. Any other voluntary resignation by you shall be
communicated by thirty (30) days' advance written notice delivery to the Chief
Executive Officer of the Company.

     (d) If your employment is terminated by the Company without cause, or by
you following a significant diminution in your responsibilities, authority or
scope of duties, a reduction in your Base Salary, relocation of your position
outside the Houston, Texas metropolitan area or a material breach of this
Agreement by the Company, and such termination occurs within one year after (i)
the effective date of a "change in control" (as defined below) or (ii) after the
execution by the Company of an agreement, the consummation of which will
constitute a "change in control," and before the effective date of a "change in
control" or cancellation of such agreement, then you shall receive the following
items as your sole compensation in lieu of the payments and benefits described
in Paragraph 3 hereof: (i) a lump sum amount equal to 2.99 times the greater of
(a) your average annual Base Salary and annual cash bonus amount pursuant to the
Company's Incentive Compensation Plan as described in Paragraph 3(b) for the
three calendar years immediately prior to the calendar year of your employment
termination date or (b) your Base Salary and target annual cash bonus amount
under


                                       2

<PAGE>

the Company's Incentive Compensation Plan as described in Paragraph 3(b) for the
year in which your employment is terminated; (ii) a lump sum amount equal to the
value of the 401(k) Plan matching contribution and Portable Retirement Plan
benefit you otherwise would have received through the end of the Term of this
Agreement; (iii) a lump sum payment equal to any unpaid portion of the Retention
Bonuses described in Paragraph 3(h); (iv) for a period of thirty-six (36) months
from your employment termination date, all medical, dental and vision benefits
the Company was maintaining for you and your family as of your employment
termination date; and (v) any employee stock options granted to you prior to or
during the Term of this Agreement shall become vested as of your employment
termination date, and you shall have the right to exercise any such vested
options through the end of the Term of this Agreement, but no event later than
the original term of the option. The continued medical, dental and vision
benefits referenced herein are contingent upon the Company and your payment of
its and your respective portion of the premium required for each such benefit.

     For purposes of this Agreement, "change in control" shall mean (1) a merger
of the Company with another entity, a consolidation involving the Company, or
the sale of all or substantially all of the assets of the Company to another
entity if, in any such case, (A) the holders of equity securities of the Company
immediately prior to such transaction or event do not beneficially own
immediately after such transaction or event equity securities of the resulting
entity entitled to 60% or more of the votes then eligible to be cast in the
election of directors generally (or comparable governing body) of the resulting
entity in substantially the same proportions that they owned the equity
securities of the Company immediately prior to such transaction or event or (B)
the persons who were members of the Board immediately prior to such transaction
or event shall not constitute at least a majority of the board of directors of
the resulting entity immediately after such transaction or event, (2) the
dissolution or liquidation of the Company, (3) when any person or entity,
including a "group" as contemplated by Section 13(d)(3) of the Exchange Act,
acquires or gains ownership or control (including, without limitation, power to
vote) of more than 20% (which percentage shall be increased to 40% in the case
of ownership or control by ChevronTexaco Corporation or a "group" of which
ChevronTexaco Corporation is a part) of the combined voting power of the
outstanding securities of, (A) if the Company has not engaged in a merger or
consolidation, the Company, or (B) if the Company has engaged in a merger or
consolidation, the resulting entity, or (4) as a result of or in connection with
a contested election of directors, the persons who were members of the Board
immediately before such election shall cease to constitute a majority of the
Board. For purposes of the preceding sentence, (i) "resulting entity" in the
context of a transaction or event that is a merger, consolidation or sale of all
or substantially all assets shall mean the surviving entity (or acquiring entity
in the case of an asset sale) unless the surviving entity (or acquiring entity
in the case of an asset sale) is a subsidiary of another entity and the holders
of common stock of the Company receive capital stock of such other entity in
such transaction or event, in which event the resulting entity shall be such
other entity, and (ii) subsequent to the consummation of a merger or
consolidation that does not constitute a Change in Control, the term "Company"
shall refer to the resulting entity and the term "Board" shall refer to the
board of directors (or comparable governing body) of the resulting entity.

     (e) If you die, or become disabled and cannot perform your duties, your
employment hereunder shall be terminated and you (or your estate) shall receive:
(i) your Base Salary for twelve (12) months following the month in which your
employment is terminated, and

<PAGE>

(ii) for a period of twelve (12) months from the date your employment is

during the term of this Agreement shall become vested as of the date of the
termination of your employment due to death or disability, and you (or your
estate) shall have the right to exercise any such vested options for a period of
twelve (12) months from the date your employment is terminated. For purposes of
this Agreement, you shall be disabled as of the first date on which you become
eligible to receive disability benefits under the Company's long-term disability
plan (or Social Security disability benefits at a time when the Company does not
maintain a long-term disability plan or such plan is not available to you).

     (f) Any termination of your employment after the expiration of the Term of
this Agreement shall be subject to the Company's practices and procedures,
including severance and other employee benefit plans.

     Unless otherwise specified herein, all payments under this Agreement shall
be paid in a lump sum, less applicable withholding taxes, within thirty (30)
days following your termination.

     3. Compensation

     (a) During the term of this Agreement, you will be paid a base annual
salary of $325,000, payable in accordance with the Company's payroll guidelines.
Your salary will be reviewed each year and may be increased, but not decreased,
in such amounts as may be determined by the Company. Increases may be made to
your Base Salary at the discretion of the Board of Directors based upon your
individual performance. There is no guarantee of a salary increase at any time.

     (b) You shall participate in the Company's Incentive Compensation Plan. The
target bonus for your position is 100% of your base annual salary, dependent
upon certain financial or performance objectives, determined in accordance with
such program, and by the Board. Your bonus compensation can be within a range of
50% to 200% of your annual base salary. Incentive awards are paid to eligible
employees based on overall company, business unit, and individual performance
with emphasis placed on competitive market reward levels and with
differentiation made for stronger performers. Award ranges are subject to change
based on market competitive norms. In the sole discretion of the Board,
incentive awards in excess of the 200% target bonus range may be made in
non-cash equivalents including, but not limited to, grants of options to
purchase shares of Class A Common Stock of the Company or grants of restricted
shares of Class A Common Stock of the Company. There is no guarantee of a bonus
payment at any time. You must be an active employee on payroll on the date the
awards are distributed to receive an award.

     (c) During the term of this Agreement, you will also be eligible to receive
an annual stock option award of Class A Common Stock of the Company, with a
value equal to a target range of 225% to 275% of your base annual salary. Such
option grants will be made dependent upon certain financial or performance
objectives, determined in accordance with such program, and by the Board. Option
grant ranges are subject to change based on market competitive norms, and the
Company may award options below the target range referenced


                                       4

<PAGE>

above in its sole discretion. There is no guarantee of a grant of options at any
time. Award ranges are subject to change based on market competitive norms. Any
options granted to you will have an exercise price equal to the highest closing
price reported on the NYSE for Class A Common Stock of the Company on the date
of grant in accordance with the requirements and provisions of the Company's
currently applicable option grant program. Any options granted during the term
of this Agreement are subject to the vesting, forfeiture and other terms and
conditions of the option grant program under which they were granted. You
recognize that any value of an award of "market" options is a projected value,
which is subject to the future performance of the Company stock, and that there
is no guarantee that the actual value of such options will achieve that value.
The valuation method to determine the actual number of stock options to be
granted will be the Black-Scholes valuation of the option on the date of grant,
as approved by the Options Committee of the Board of Directors of the Company.

     (d) You shall be eligible to participate in such other plans and receive
such other perquisites as the Board of Directors of the Company in its sole
discretion determines, including, but not limited to, four (4) weeks of paid
vacation per annum.

     (g) You agree to repay the Company all amounts that you owe under the
Short-Term Executive Stock Purchase Loan Program of Dynegy Inc. in accordance
with the terms of that program.

still employed the by Company, Company shall pay to Employee a Retention Bonus
of $155,000.00.

     4. Confidentiality, Non-Competition and Non-Solicitation.

     You recognize and acknowledge that:

     (a) You will have access to certain information concerning the Company that
is confidential and proprietary and constitutes valuable and unique property of
the Company. You agree that you will not at any time, either during or after
your employment, disclose to others, use, copy or permit to be copied, except
pursuant to your duties on behalf of the Company or its successors, assigns or
nominees, any secret or confidential information of the Company (whether or not
developed by you) without the prior written consent of the Board of Directors of
the Company. The term "secret or confidential information of the Company"

training and recruiting procedures; accounting procedures; the status and
content of the Company's contracts with its suppliers or clients; or servicing
methods and techniques at any time used, developed, or investigated by the
Company; before or during your tenure of employment to the extent any of the
foregoing are (i) not generally available to the public and (ii) maintained as
confidential by the Company. You further agree to maintain in confidence any
confidential information of third parties received as a result of your
employment and duties with the Company.

     (b) At the termination of your employment you will deliver to the Company,
as determined appropriate by the Company, all correspondence, memoranda, notes,
records, client lists, computer systems, programs, or other documents and all
copies thereof made, composed or received by you, solely or jointly with others,
and which are in your possession, custody, or control at such date and which are
related in any manner to the past, present, or anticipated business of the
Company.

     (c) To protect and safeguard the Company's trade secrets and Confidential
Information and also the Company's goodwill with its suppliers and clients, for
a period of six (6) months following the termination of your employment for any
reason you will not, within a 50 mile radius of the Company's principal office,
without the prior written consent of the Board of Directors of the Company,
directly or indirectly, engage in (as owner, partner, shareholder, employee,
director, agent, consultant or otherwise) any business which is a competitor of
the Company, as hereinafter defined. The restrictions contained in the preceding
paragraph shall not apply in the event the Company repudiates this Agreement or
if you have not received all compensation for which you are eligible in
Paragraph 3 herein. For purposes of this Agreement, a "competitor of the
Company" is any entity, including without limitation a corporation, sole
proprietorship, partnership, joint venture, syndicate, trust or any other form
of organization or a parent, subsidiary or division of any of the foregoing,
which, during such period or the immediately preceding fiscal year of such
entity, was engaged in the unregulated marketing, gathering, transportation or
processing of natural gas or derivatives of natural gas or other hydrocarbons or
electricity. For purposes of this paragraph, the following entities shall not be
deemed to be competitors of the Company: (i) a Local Distribution Company; (ii)
a company which is predominantly an oil or natural gas producer; (iii) a natural
gas pipeline company in the jurisdictional aspects of its business, or (iv) an
integrated regulated electric and/or gas utility, as long as the utility does
not engage in the unregulated marketing of its generation or power trading other
than that related to the generation and power marketing allocated to its own
service areas. The terms of this Paragraph 4(c) shall not apply to your present
or future investments in the securities of companies listed on a national
securities exchange or traded on the over-the-counter market to the extent such
investments do not exceed one percent (1%) of the total outstanding shares of
such company.

     (d) For a period of two (2) years after the expiration or termination of
your employment for whatever reason, you shall not, either on your own behalf or
on behalf of your new employer (either directly or indirectly via a corporate
recruiter or headhunter) induce or otherwise entice any employee of the Company
to leave the Company, nor shall you attempt to hire any of the Company's
employees.


                                       6

<PAGE>

     (e) You agree that the foregoing restrictions contain reasonable
limitations as to the time, geographical area, and scope of activity to be
restrained and that these restrictions do not impose any greater restraint than
is necessary to protect the goodwill and other legitimate business interests of
the Company, including but not limited to the protection of Confidential
Information. You also agree that the general public shall not be harmed by
enforcement of this Paragraph 4. Should any provision in this Paragraph 4 be
held unreasonably broad with respect to the restrictions as to time,
geographical area, or scope of activity to be restrained, any such restriction
shall be construed by limiting and reducing it to the extent necessary to render
it reasonable, and as so construed, such provision shall be enforced.

     Accordingly, you consent and agree that if you violate any of the
provisions of this Paragraph 4, the Company and its subsidiaries and affiliated
companies would sustain irreparable harm and, therefore, in addition to any
other remedies which the Company may have under this Agreement or otherwise, the
Company shall be entitled to an injunction from any court of competent
jurisdiction restraining you from committing or continuing any such violation of
this Paragraph. You acknowledge that damages at law would not be an adequate
remedy for violation of this Paragraph 4, and you therefore agree that the
provisions of this Paragraph 4 may be specifically enforced against you in any
court of competent jurisdiction. Nothing herein shall be construed as
prohibiting the Company from pursuing any other remedies available to the
Company for such breach or threatened breach, including the recovery of damages
from you.

     5. Arbitration

     The parties hereto may attempt to resolve any dispute hereunder informally
via mediation or other means. Otherwise, any controversy or claim arising out of
or relating to this Agreement, or any breach thereof, shall, except as provided
in Paragraph 4, be adjusted only by arbitration in accordance with the rules of
the American Arbitration Association, and judgment upon such award rendered by
the arbitrator may be entered in any court having jurisdiction thereof. The
arbitration shall be held in the City of Houston, Texas, or such other place as
may be agreed upon at the time by the parties to the arbitration. The
arbitrator(s) shall, in their award, allocate between the parties the costs of
arbitration, which shall include reasonable attorneys' fees of the parties, as
well as the arbitrator's fees and expenses, in such proportions as the
arbitrator deems just.

     6. Indemnification

     If, at any time during or after the Term of this Agreement, you are made a
party to, or are threatened to be made a party in, any civil, criminal or
administrative action, suit or proceeding by reason of the fact that you are or
were a director, officer, employee, or agent of the Company, or of any other
corporation or any partnership, joint venture, trust or other enterprise for
which you served as such at the request of the Company, then you shall be
indemnified by the Company, to the fullest extent permitted under applicable
law, against expenses actually and reasonably incurred by you or imposed on you
in connection with, or resulting from, the defense of such action, suit or
proceeding, or in connection with, or resulting from, any appeal therein if you
acted in good faith and in a manner you reasonably believed to be in or not
opposed to the best interests of the Company, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe your conduct was
unlawful, except with


                                       7

<PAGE>

respect to matters as to which it is adjudged that you are liable to the Company
or to any other corporation, partnership, joint venture, trust, enterprise or
third party individual for gross negligence or willful misconduct in the
performance of your duties. As used herein, the term "expenses" shall include
all obligations actually and reasonably incurred by you for the payment of
money, including, without limitation, attorneys' fees, judgments, awards, fines,
penalties and amounts paid in satisfaction of a judgment or in settlement of any
such action, suit or proceeding, except amounts paid to the Company or such
other corporation, partnership, joint venture, trust or other enterprise by you.
The foregoing indemnification provisions shall be in addition to any other
rights to indemnification to which you may be entitled.

     7. Other Provisions

     (a) THIS AGREEMENT WILL BE GOVERNED BY, CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, EXCLUDING ANY CONFLICTS OF LAW,
RULE OR PRINCIPLE THAT MIGHT OTHERWISE REFER TO THE SUBSTANTIVE LAW OF ANOTHER
JURISDICTION.

     (b) Except as otherwise indicated, this Agreement is not assignable without
the written authorization of both parties; except that the Company may assign
this Agreement to any entity to which the Company transfers substantially all of
its assets or to any entity which is a successor to the Company by
reorganization, incorporation, merger or similar business combination.

and their legal representatives and authorized by action of the Board. Except as

subsequent breach of such condition or provision or a waiver of a similar or
dissimilar provision or condition at the same or at any prior or subsequent
time.
