Re: Technology Purchase and Royalty Agreement

Dear Sirs:

This is to confirm our mutual agreement that the term "cocaine" as used in
the Technology Purchase Agreement dated as of March 12, 2003, by and between
Hythiam Inc. ("Hythiam") and Tratamientos Avanzados de la Adiccion S.L. ("TAVAD"
formerly known as CITA S.L.") shall be deemed to include "crack cocaine" in all
places that such term is used in the Agreement, except for Section 12.4. Tavad
does not warrant that the Intellectual Property constitutes all technology and
know-how necessary for crack cocaine detoxification procedures. Without limiting
the generality of the foregoing, it is the sole responsibility of Hythiam to
determine the procedures and know-how for use of the Intellectual Property in
crack cocaine detoxification procedures, including the safety and efficacy of
such procedures.

The Technology Purchase Agreement, as amended by this Letter Agreement
remains in full force and effect.

Kindly acknowledge your agreement to the foregoing by signing a copy of
this letter where indicated.

Very truly yours,

TAVAD S.L.

Date, SELLER shall sell, transfer, assign and convey (the "Transfer")
exclusively to BUYER, and BUYER shall purchase from SELLER, free and clear of
all liens, claims and encumbrances (except as set forth on Schedule B), all of

obligations under this Agreement.

(b) SELLER expressly reserves all rights in and to the

(a) As partial consideration for the sale of the Intellectual
Property, BUYER will issue to SELLER shares of its common stock (the "Shares")
following consummation of the first equity financing (the "First Equity
Financing") of BUYER which raises gross proceeds of at least $5,000,000. The
number of shares that will be issued will represent five percent (5%) of BUYER's

-2-

outstanding capital stock after the consummation of the First Equity Financing,
assuming that (i) any shares of convertible preferred stock or warrants have
been converted into or exercised for, as applicable, common stock at the
then-applicable conversion or exercise rate and (ii) only $5,000,000 of shares
were issued at the sale price in the First Equity Financing (regardless of the
number of shares actually issued). Notwithstanding the foregoing, SELLER's
percentage ownership interest in the shares of common stock of BUYER shall not
be reduced to less than 4.5% (on a fully diluted basis after giving effect to
the exercise of all Convertible Securities) upon the completion of the first
$10,000,000 in equity financing that is raised by BUYER

(b) As a condition to receiving the shares described in
Section 2.1.2(a), BUYER will have to (x) deliver to SELLER an appropriate
investor representation letter to establish that BUYER may issue the shares to
SELLER in compliance with applicable federal and state securities laws and a
properly completed Form W-8BEN and (y) at BUYER's option, either (i) become a
party to any stockholder, investor rights or similar agreement ("Investor
Agreement(s)") entered into in connection with the First Equity Financing;
provided that such Investor Agreement(s) is in a form reasonably satisfactory to
SELLER and pursuant to which SELLER shall be subject to the same rights (except
as to board representation and as set forth in the last sentence hereof) and
obligations as BUYER's founding stockholder or (ii) sign an investor agreement
in form reasonably satisfactory to BUYER and SELLER (which may be part of the
investor representation letter) which will, among other things, limit transfer
of the shares, grant BUYER a right of first refusal (subject to customary
exceptions), and provide for a lock-up of up to 180 days in connection with a
public offering by BUYER; provided, that SELLER shall not be under any greater
restriction under the lock-up than BUYER's founding stockholders. The Investor
Agreement(s) or investor representation letter will grant SELLER unlimited
piggyback registration rights with respect to the shares of common stock
(including the shares issuable upon exercise of any options) of BUYER owned by
SELLER, subject to customary terms, conditions and restrictions. The Investor
Agreement shall also grant SELLER the right to put its shares of common stock
(including the shares issuable upon exercise of the options) to BUYER at a
purchase price equal to their fair market value if BUYER shall not have
completed an initial public offering or a Reverse Merger within three years
following the Closing Date

(c) For the gross proceeds, if any, between $5,000,000 and
$10,000,000 raised in the First Equity Financing, BUYER will also issue to
SELLER stock options up to an additional two percent (2%) of BUYER's common
stock, assuming that any shares of convertible preferred stock or warrants have
been converted into or exercised for, as applicable, common stock at the
then-applicable conversion or exercise rate Such stock options will be granted
on a pro rata basis depending on the exact amount of such proceeds raised (e.g.,
if $7,500,000 of gross proceeds are raised in the First Equity Financing, BUYER
will issue to SELLER stock options to purchase one percent (1%) of BUYER's
common stock). The stock option grant will be made subject to the same
conditions described above for the stock grant and will be made pursuant to
BUYER's standard form of stock option agreement satisfactory to BUYER, will have
an exercise price equal to the per share price in the First Equity Financing,
and will have such vesting and other provisions that are no less favorable than
the options granted to BUYER's senior officers.

-3-

(d) SELLER understands that BUYER may raise some or all of the
First Equity Financing through a reverse merger (a "Reverse Merger") with an
existing public company ("Merger Partner"). In the event BUYER consummates a
Reverse Merger, (i) the net working capital (determined in accordance with
generally accepted accounting principles) of the Merger Partner as of the
closing of the Reverse Merger, net of long-term debt in excess of $1,000,000 and
(ii) cash obtained upon the sale of any marketable securities held by a Merger
Partner shall be treated as proceeds of an equity financing (such that if Merger
Partner had $4,000,000 of net working capital and no long-term liabilities and
Buyer raised $3,000,000 in a separate equity financing, then, as of the
consummation of the Reverse Merger, BUYER shall be deemed to have engaged in a
First Equity Financing which raised $7,000,000) and (ii) SELLER will receive
common stock of the Merger Partner and options to purchase common stock of the
Merger Partner on a basis otherwise consistent with the terms set forth in the
other clauses of this Section 2.1.2.

2.1.3 CONTINUING ROYALTIES.

(a) BUYER shall pay SELLER Continuing Royalties of Three
Percent (3%) of gross sales of alcohol or cocaine detoxification Process

all collected funds for each Payment Period no later than the Payment Date.

(c) BUYER shall tender payments of the Continuing Royalties
due on each Payment Date by wire transfer to such account or accounts as SELLER
may designate in advance.

(d) BUYER shall pay the Continuing Royalties in US Dollars.

(e) BUYER's obligation to pay Continuing Royalties to SELLER
shall terminate after the public disclosure (other than as a result of a breach
by BUYER of Section 8.1) of all Intellectual Property knowhow and the expiration
of the last to expire of all Intellectual Property patents that are enforceable
within the Territory.

(f) In the event that Buyer shall make any improvements to the
Intellectual Property, BUYER shall continue to be obligated to pay Continuing
Royalties of Three Percent (3%) to SELLER of gross sales of alcohol or cocaine
detoxification Processes BUYER (or any licensee) performs using the Intellectual
Property and any improvements thereto.

(the "Closing Date") on which this Agreement is executed by the parties hereto
or at such later date and/or other place as the parties shall mutually agree
upon.

-4-

(b) At the Closing, SELLER shall deliver to BUYER a duly
executed general ▇▇▇▇ of sale and assignment of the Intellectual Property and
any other documents of transfer requested by BUYER necessary to convey all of
SELLER's right, title and interest in and to the Intellectual Property to BUYER,
in recordable form, if required.

(c) At the Closing, BUYER shall deliver to SELLER a duly
executed security agreement, substantially in the form of Exhibit 1 hereto,
granting SELLER a first priority security interest in the Intellectual Property
to secure SELLER's reversion rights pursuant to Section 2.6 and Section 2.7.

2.3 FURTHER ASSURANCES. At any time and from time to time after the
Closing Date and after the delivery of all of the initial documents and
necessary information that comprise the Intellectual Property at BUYER's request
and approved expense, and subject to the terms of this Agreement, SELLER
promptly shall execute and deliver, and shall cause its affiliates and employees
to execute and deliver, such instruments of sale, transfer, conveyance,
assignment and confirmation, and take such other action, as BUYER may reasonably
request to more effectively transfer, convey and assign to BUYER, and to confirm
BUYER's title to, all of the Intellectual Property, including providing to BUYER
an executed assignment to BUYER, recordable in the appropriate regional or
national patent office, for each patent and patent application within the
Intellectual Property and specifically claiming the Field, to assist BUYER in
exercising all rights with respect thereto and to carry out the purpose and
intent of this Agreement.

2.4 RESTRICTION ON TRANSFER OF THE INTELLECTUAL PROPERTY.

2.4.1 BUYER may not Transfer the Intellectual Property or any right
or obligation under this Agreement, except as permitted by this Section 2.4. Any
attempted Transfer, except as permitted by this Section 2.4 is void.

2.4.2 BUYER may not Transfer the Intellectual Property separate from
all of its rights and obligations under this Agreement. In addition, BUYER may
not Transfer any of its rights or obligations under this Agreement separate from
the Intellectual Property.

2.4.3 BUYER may Transfer the Intellectual Property, together with
all of its rights and obligations under this Agreement, to another person or
entity reasonably satisfactory to SELLER; provided that SELLER's consent shall
not be required in connection with such a Transfer (i) in whole or in part to a
direct or indirect subsidiary of BUYER or (ii) in connection with a merger
(including a Reverse Merger), consolidation, sale of substantially all assets or
other similar corporate transaction by or involving BUYER. In connection with
any proposed Transfer,

(a) The proposed transferee must assume in writing all of
BUYER's obligations under this Agreement, including any of BUYER's obligations
which arose prior to the effective date of Transfer.

(b) The proposed transferee's assumption of BUYER's
obligations under this Agreement will NOT relieve BUYER of any liability which
BUYER has to SELLER under this Agreement for the failure of BUYER or the
proposed transferee to perform all of BUYER's obligations under this Agreement,
unless, at BUYER's request, SELLER approves of transferee, which approval shall

-5-

not be unreasonably withheld, and all of BUYER's obligations and liabilities are
then transferred to transferee.

2.4.4 BUYER will use its commercially reasonable efforts to provide
in any license that BUYER may grant to any third party for use of the
Intellectual Property that (i) licensee shall pay directly to SELLER directly
the Continuing Royalties (the "Equivalent Royalties") that BUYER would be
obligated to pay to SELLER pursuant to Section 2.1.3 on account of any Processes
performed by licensee using the Intellectual Property and (ii) SELLER shall have
the right to enforce such obligation directly against licensee as a third party
beneficiary. Any such Continuing Royalties paid to SELLER by any such licensee
shall be credited against BUYER's royalty payment obligations to SELLER. The
failure to include a "direct payment" obligation in any license granted by BUYER
to any third party shall not release BUYER from its obligation to pay to SELLER
the Equivalent Royalties.

2.4.5 Nothing in this Section 2.4 is meant, or shall be construed,
to limit BUYER's right to Exploit the Intellectual Property as described in
Section 2.1.1 hereof.

2.5 REQUIREMENTS FOR USE OF INTELLECTUAL PROPERTY. The Intellectual
Property may only be used to perform detoxification processes (the "Processes")
on persons for alcohol and/or cocaine addiction (the "Field"). Without limiting
the generality of the foregoing sentence, BUYER shall not directly or indirectly
use the Intellectual Property to treat any physical or psychological condition
other than alcohol addiction and/or cocaine addiction. BUYER must have
reasonable grounds to believe that any person on whom a Process is performed is
a resident of the Territory. Subject to the last sentence of this paragraph, the
Processes may only be performed in a licensed medical facility (the "Medical
Center") within the Territory, by one or more Healthcare Providers. A Healthcare
Provider may perform evaluation and diagnosis and follow-up care using the
Intellectual Property in a Healthcare Provider Officer, provided that the
Process is performed in a Hospital.

2.6 DILIGENCE.

2.6.1 Until the earlier of (i) the fifth anniversary of the date of
this Agreement or (ii) the date when BUYER has paid to SELLER royalties and, if
applicable Additional Payments (as defined below) pursuant to this Agreement of
at least $1,000,000 (the "Reversion Term"), BUYER agrees that, unless otherwise
agreed to by SELLER, BUYER will allocate during each fiscal year at least fifty
percent (50%) (the "Requisite Percentage") of the funds it expends on sales,
marketing, research and development (the "Exploitation Activities") on
Exploitation Activities relating to use of the Intellectual Property, including
any changes or improvements to the Intellectual Property (the "Technology

Partner), then SELLER may terminate this Agreement and the rights to the
Intellectual Property shall revert to SELLER upon written notice delivered by
SELLER to BUYER within thirty days after BUYER notifies SELLER in writing that

termination will not affect the rights of any licensee or transferee of BUYER
