                              a Nevada corporation

      This Warrant certifies that James W. Christian ("Purchaser"), is entitled
to purchase from iExalt, Inc., a Nevada corporation (the "Company"), the Shares
(as defined herein) in the amounts and at the Exercise Price (as defined
herein), all on the terms and conditions hereinafter provided.

      Section 1. Certain Definitions. As used in this Warrant, unless the
context otherwise requires:

      "Affiliate" shall mean: (i) any Person directly or indirectly controlling,
controlled by, or under common control with, another Person; (ii) any Person
owning or controlling ten (10%) percent or more of the outstanding voting
securities of another Person; (iii) any officer, director or partner of a
Person; and (iv) if a Person is an officer, director or partner, any such
company for which such Person acts in such capacity.

      "Articles" shall mean the Certificate of Incorporation of the Company, as
in effect from time to time.

      "Common Stock" shall mean the Company's authorized common stock, $0.001
par value per share.

      "Exercise Price" shall mean the exercise price of $0.1406 per share of
Common Stock as determined as follows, as adjusted from time to time pursuant to
Section 3 hereof.

      "Expiration Date" shall mean five (5) years from the date of Closing.

      "Securities Act" shall mean the Securities Act of 1933, as amended.

      "Shares" shall mean the number of shares of the Company's common stock.

      "Warrant" shall mean this Warrant and all additional or new warrants
issued upon division or combination of, or in substitution for, this Warrant.
All such additional or new warrants shall at all times be identical as to terms
and conditions and date, except as to the number of shares of Common Stock for
which they may be exercised.

      "Warrant Stock" shall mean the shares of Common Stock purchasable by the
holder of this Warrant upon the exercise of such Warrant.

      "Warrantholder" shall mean Purchaser, as the initial holder of this
Warrant, and its nominees, successors or assigns, including any subsequent
holder of this Warrant to whom it has been legally transferred.

      Section 2. Amount of Shares and Exercise of Warrant.

      (a) Upon signing this Warrant Agreement, the Company has issued separate
warrants to Purchaser, entitling Purchaser to purchase 300,000 shares of Company
common stock. The warrants issued this date to Purchaser are each fully vested
and earned.

      (a.1) At any time after the date hereof through and including the
Expiration Date, Purchaser may at any time and from time to time exercise this
Warrant, in whole or in part.


                                       1
<PAGE>

      (b) Warrantholder may exercise this Warrant by means of delivering to the
Company at its principal office: (i) a written notice of exercise, including the
number of Shares of Warrant Stock to be delivered pursuant to such exercise and
identifying whether the exercise is being made by cash purchase or conversion of
shares of common stock; (ii) this Warrant; and (iii) if applicable, payment
equal to the Exercise Price multiplied by the number of shares exercised. In the
event that any exercise shall not be for all Shares of Warrant Stock purchasable
hereunder, the Company shall deliver to Warrantholder a new Warrant registered
in the name of Warrantholder, of like tenor to this Warrant and for the
remaining shares of Warrant Stock purchasable hereunder, within ten (10) days of
any such exercise. The notice of exercise described in clause (i) shall be in
the Subscription Form set out at the end of this Warrant.

      Warrantholder may elect to pay the Exercise Price to the Company
either:(1) by cash, certified check or wire transfer: (2) by converting the
Warrant into Common Stock ("Warrant Conversion"); or (3) any combination of the
foregoing. Such election of the form of payment of the Exercise Price shall be
specified in the Subscription Form. If Warrantholder elects to pay the Exercise
Price through Warrant Conversion, the Company shall deliver to Warrantholder
(without payment by Warrantholder of any cash or other consideration) that
number of shares of Common Stock equal to the difference of: (I) the total
number of shares of Common Stock issuable upon exercise of this Warrant minus
(II) that number of Shares of Common Stock having an aggregate "Value" (as
defined herein) equal to the aggregate Exercise Price. For purposes of this
Section 2, "Value" per share of Common Stock shall be the difference, as of the
date of exercise, between the Exercise Price and the Fair Market Value (as
determined either by the average closing price of the Company for the 5 trading
days immediately preceding the conversion as reported in The Wall Street Journal
(Southwest Edition) or, if the Company is no longer public (through de-listing,
change of control or otherwise), the Fair Market Value as determined by mutual
agreement of the Company and Purchaser (including appropriate discounts for
illiquidity, minority and lack of marketability), and if such cannot be mutually
agreed, then as determined by an independent appraiser expert in the industry,
the cost of which would be shared equally by the Company and the Warrantholder.

Notwithstanding the foregoing, Purchaser may utilize Warrant Conversion to pay
the Exercise Price only for a maximum of 50% of the total Warrant Stock. Each
transaction involving payment of the Exercise Price can be made at the
discretion of the purchaser up to 100% "cashless" warrant conversion.

      (c) Upon exercise of this Warrant and delivery of the Subscription Form
with proper payment relating thereto, the Company shall cause to be executed and
delivered to Warrantholder as soon as possible, and in no event later than five
business days thereafter, a certificate or certificates representing the
aggregate number of fully-paid and nonassessable shares of Common Stock issuable
upon such exercise.

      (d) The stock certificate or certificates for Warrant Stock to be
delivered in accordance with this Section 2 shall be in such denominations as
may be specified in the Subscription Form, and shall be registered in the name
of Warrantholder or such other name or names as shall be designated in said
Subscription Form. Such certificate or certificates shall be deemed to have been
issued, and Warrantholder or any other person so designated to be named therein
shall be deemed to have become the holder of record of such shares, including to
the extent permitted by law the right to vote such shares or to consent or to
receive notice as stockholders, as of the time said Subscription Form is
delivered to the Company as aforesaid.

      (e) The Company shall pay all expenses payable in connection with the
preparation, issue and delivery of stock certificates under this Section 2;
provided, however, that Warrantholder shall pay any transfer taxes resulting
from the exercise of the Warrant and the issuance of Warrant Stock hereunder.

      (f) All shares of Warrant Stock issuable upon the exercise of this Warrant
in accordance with the terms hereof shall be validly issued, fully paid and
nonassessable, and free from all liens and other encumbrances thereon, other
than liens or other encumbrances created by Warrantholder.


                                       2

      (g) In no event shall any fractional share of Common Stock of the Company
be issued upon any exercise of this Warrant. If, upon any exercise of this
Warrant, Warrantholder would, except as provided in this paragraph, be entitled
to receive a fractional share of Common Stock, then the Company shall deliver in
cash to such holder an amount equal to such fractional interest.

      Section 3. Adjustment of Exercise Price and Warrant Stock.

      (a) If, at any time prior to the Expiration Date, the number of
outstanding shares of Common Stock is: (i) increased by a stock dividend payable
in shares of Common Stock or by a subdivision or split-up of shares of Common
Stock; or (ii) decreased by a combination of shares of Common Stock, then,
following the dividend or effective date of such stock dividend, subdivision,
split-up, or combination, the Exercise Price shall be adjusted to a new amount
equal to the product of (I) the Exercise Price in effect on such record date,
and (II) the quotient obtained by dividing (x) the number of shares of Common
Stock outstanding on such record date (without giving effect to the event
referred to in the foregoing clause (i) or (ii)), by (y) the number of shares of
Common Stock which would be outstanding immediately after the event referred to
in the foregoing clause (i) or (ii), if such event had occurred immediately
following such record date.

      (b) If, after the date of Closing, and at any time prior to the Expiration
Date, the Company issues or sells shares of its Common Stock or any other shares
of its Common Stock or any other securities convertible into or exchangeable for
Common Stock ("Convertible Securities"), or in any manner grants or reprices any
warrants, options or other rights (collectively, "Options") to purchase shares
of Common Stock or Convertible Securities, after the date hereof, which entitles
the subscriber, or the holder of such Option or Convertible Security, to
purchase any shares of Common Stock at less than the then current Exercise Price
(or the Exercise Price as ultimately determined pursuant to the definition of
Exercise Price), then the Exercise Price in effect immediately prior to such
action by the Company shall be adjusted to equal the price at which any such
subscriber or holder shall be entitled to purchase any such shares of Common
Stock.

      (c) In the event that either of the events described in Section 3(a) or
Section 3(b) shall occur prior to the determination of the Exercise Price
(pursuant to the definition of such term), then immediately upon the occurrence
of the event that shall cause the determination of the Exercise Price pursuant
to such definition, such Exercise Price shall immediately be adjusted in
accordance with this Section 3.

      (d) Upon each adjustment of the Exercise Price as provided in Section 3(a)
or Section 3(b), Warrantholder shall thereafter be entitled to subscribe for and
purchase, at the Exercise Price resulting from such adjustment, the number of
shares of Warrant Stock equal to the product of: (i) the number of shares of
Warrant Stock existing prior to such adjustment; and (ii) the quotient obtained
by dividing (I) the Exercise Price existing prior to such adjustment by (II) the
new Exercise Price resulting from such adjustment.

      (e) If, at any time prior to the Expiration Date, there occurs an event
which would cause the automatic conversion ("Automatic Conversion") of the
Warrant Stock into shares of the Company's common stock ("Common Stock") in
accordance with the Articles, then any Warrant shall thereafter be exercisable,
prior to the Expiration Date, into the number of shares of Common Stock into
which the Warrant Stock would have been convertible pursuant to the Articles if
the Automatic Conversion had not taken place.

      Section 4. Division and Combination. This Warrant may be divided or
combined with other Warrants upon presentation at the office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by Warrantholder or its agent or attorney.
The Company shall pay all expenses in connection with the preparation, issue and
delivery of Warrants under this Section 4, including any transfer taxes
resulting from the division or combination hereunder. The Company agrees to
maintain at its office books for the registration of the Warrants.

      Section 5. Reclassification, Etc. In case of any reclassification or
change of the outstanding Common Stock of the Company (other than as a result of
a subdivision, combination or stock dividend), or in case of any consolidation
of the Company with, or merger of the Company into, another corporation or other
business


                                       3
<PAGE>

organization (other than a consolidation or merger in which the Company is the
continuing corporation and which does not result in any reclassification or
change of the outstanding Common Stock of the Company), at any time prior to the
Expiration Date, then, as a condition of such reclassification, reorganization,
change, consolidation or merger, lawful provision shall be made, and duly
executed documents evidencing the same from the Company or its successor shall
be delivered to Warrantholder, so that Warrantholder shall have the right prior
to the Expiration Date to purchase, at a total price not to exceed that payable
upon the exercise of this Warrant, the kind and amount of shares of stock and
other securities and property receivable upon such reclassification,
reorganization, change, consolidation or merger by a holder of the number of
shares of Common Stock of the Company which might have been purchased by
Warrantholder immediately prior to such reclassification, reorganization,
change, consolidation or merger, and in any such case appropriate provisions
shall be made with respect to the rights and interest of Warrantholder to the
end that the provisions hereof (including provisions for the adjustment of the
Exercise Price and of the number of shares purchasable upon exercise of this
Warrant) shall thereafter be applicable in relation to any shares of stock and
other securities and property thereafter deliverable upon the exercise of this
Warrant.

      Section 6. Reservation and Authorization of Capital Stock. The Company
shall at all times reserve and keep available for issuance such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants.

      Section 7. Stock and Warrant Books. The Company will not at any time,
except upon dissolution, liquidation or winding up, close its stock books or
Warrant books so as to result in preventing or delaying the exercise of any
Warrant.

      Section 8. Limitation of Liability. No provisions hereof, in the absence
of affirmative action by Warrantholder to purchase Warrant Stock hereunder,
shall give rise to any liability of Warrantholder to pay the Exercise Price or
as a stockholder of the Company (whether such liability is asserted by the
Company or creditors of the Company).

      Section 9. Registration Rights. The Warrant Stock issuable upon exercise
of this Warrant is subject to the provisions of a certain Registration Rights
Agreement, dated the same date as this Warrant, by and among the Company,
Purchaser and the other Lenders.

      Section 10. Transfer. Subject to compliance with the Securities Act and
the applicable rules and regulations promulgated thereunder, this Warrant and
all rights hereunder shall be transferable in whole or in part. Any such
transfer shall be made at the offices of the Company at which this Warrant is
exercisable by Warrantholder or its duly authorized attorney upon surrender of
this Warrant together with an assignment hereof properly endorsed. Promptly
thereafter a new warrant shall be issued and delivered by the Company,
registered in the name of the assignee. Until registration of the transfer of
this Warrant on the books of the Company, the Company may treat Purchaser as the
owner hereof for all purposes.

      Section 11. Investment Representations; Restrictions on Transfer of
Warrant Stock. Unless a current registration statement under the Securities Act
shall be in effect with respect to the Warrant Stock to be issued upon exercise
of this Warrant, Warrantholder, by accepting this Warrant, covenants and agrees
that, at the time of exercise hereof, and at the time of any proposed transfer
of Warrant Stock acquired upon exercise hereof, Warrantholder will deliver to
the Company a written statement that the Warrant Stock acquired by Warrantholder
upon exercise hereof is for the account of Warrantholder (or is being held by
Warrantholder as trustee, investment manager, investment advisor or as any other
fiduciary for the account of the beneficial owner or owners) for investment, and
is not being acquired with a view to, or for sale in connection with, any
distribution thereof (or any portion thereof), and with no present intention (at
any such time), of offering and distributing such Warrant Stock (or any portion
thereof). The Warrant Stock may contain a standard securities law restrictive
legend reasonably required by the Secretary of the Company.

      Section 12. Loss, Destruction of Warrant. Upon receipt of evidence
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction, upon receipt of
indemnity and/or security reasonably satisfactory to the Company or, in the case
of any such mutilation, upon surrender and cancellation of such Warrant, the
Company will make and deliver, in lieu of such lost, stolen, destroyed or
mutilated Warrant, a new Warrant of identical tenor and representing the right
to purchase the same aggregate number of shares of Common Stock.

      Section 13. Accredited Investor. Warrantholder represents that
Warrantholder is an accredited investor in all respects as defined under the
Securities Exchange Act and all other Federal and State Regulations.

      Section 14. Amendments. The terms of this Warrant may be amended, and the

of the Company and Warrantholder.

      Section 15. Notices Generally. Any notice, request, consent, other

facsimile number appearing on the books of the Company, or, except as herein
otherwise expressly provided, to the Company at its principal executive office,
or such other address or facsimile number as shall have been furnished to the
party giving or making such notice, demand or delivery.

      Section 16. Successors and Assigns. This Warrant shall bind and inure to
the benefit of and be enforceable by the parties hereto and their respective
permitted successors and assigns which shall be limited to Affiliates of the
holder hereof.

      Section 17. Arbitration. The parties agree that any dispute arising
hereunder will be subject to Christian mediation. The parties will endeavor to
choose a neutral, third-party Christian mediator who does not have a personal
relationship with either, and on whom they can both agree. If the parties are
unable to reach written agreement on a mediator, then each will choose one
neutral Christian mediator from the list of Christian mediators in any credible
Christian mediation organization, and within fifteen (15) days those chosen
individuals will choose a mediator appropriate for this mediation. If the
parties are unable to reach an agreement through mediation, both agree to submit
their dispute to binding arbitration within ninety (90) days from the selection
of the arbitrator. If after thirty (30) days from the unsuccessful mediation,
the parties are unable to reach a written agreement on an arbitrator, then the
process for choosing a mediator outlined previously in this paragraph will be
instituted to aid in the appointment of an arbitrator. The appointment shall be
binding.

      Section 18. Governing Law. IN ALL RESPECTS, INCLUDING ALL MATTERS OF

For Immediate Release                                               Exhibit 99.2

iExalt, Inc. Acquires Capital Artist Agency, Inc.
Acquisition of Christian talent agency leverages presence in entertainment
services sector.

HOUSTON--(March 12, 2001)--iExalt, Inc. (OTCBB:IXLT), a Christian product and
services company with significant Internet-related activities, announced today
that it has completed the acquisition of Capital Artist Agency, Inc., a full
service talent agency representing a variety of names in contemporary Christian
music headquartered in Nashville, TN. The stock transaction will substantially
increase iExalt's presence in the Christian entertainment services sector.
Effective immediately, Capital Artist Agency will become ChristianArtists.com.

The Capital Artist acquisition continues iExalt's dominance of the Christian
event bookings market, which began last year with the acquisitions of
ChristianSpeakers.com and Alive Communications Speakers Bureau. The two
organizations will complement each other and leverage their respective areas of
influence through their close association. As a result, iExalt becomes a
complete resource for many of the Christian community's talent needs in booking
speakers and artists. Formed in 1993, Capital Artist Agency represents many
notable names in contemporary Christian music, including Truth, Alicia
Williamson, Aaron Jeoffrey, Lenny LeBlanc, Dennis Swanberg, Total Praise and
others.

Donald W. Sapaugh, chairman and chief executive officer of iExalt, Inc. said,
"ChristianArtists.com represents an additional opportunity for iExalt to harness
the power of the Internet by enabling our customers to access a growing list of
additional services from a single source. ChristianArtists.com's focus is on the
local church, where iExalt already has significant relationships. Jeremy
Breland, president of ChristianArtists.com, is a committed leader who is
experienced in the industry. With his vision and relationships, we believe the
event segment has significant growth potential."

Breland said, "The synergy between ChristianArtists.com and the other companies
in the iExalt family make for a perfect match. ChristianArtists.com fits quite
well in the services branch of iExalt's model. At the same time, our exposure
through the other corporate divisions and leveraging iExalt's brand and network
of related products will provide tremendous opportunity for growth over the next
several years. I believe this will be a win-win situation in every sense for
both iExalt and ChristianArtists.com."
