                         FOR THE PURCHASE OF SHARES OF
                                  COMMON STOCK
                                       OF
                           INFE-HUMAN RESOURCES, INC.

THIS WARRANT, DATED AS OF APRIL 26, 2007, CERTIFIES THAT, FORVALUE RECEIVED, Jay
O. Wright (the "Holder"), is entitled to subscribe for and purchase from Infe-
Human Resources, Inc., a Nevada corporation (the "Company"), 1,000,000 shares of
Common Stock of the Company, at an exercise price of $0.50 (the "Exercise
Price") subject to adjustment as provided herein.

1.	Definitions.  When used in this Warrant, the following terms shall have
the meanings specified:

a.	"Common Stock" shall mean the common stock of the Company.

b.	"Convertible Securities" means evidences of indebtedness, shares of
stock or other securities which are convertible into or exchangeable for, with
or without payment of additional consideration in cash or property, additional
shares of Common Stock, either immediately or upon the arrival of a specified
date or the happening of a specified event.

c.	"Exercise Notice" shall mean a notice of exercise of all or any portion
of this Warrant, in the form attached hereto as Exhibit A.

d.	"Expiration Date" shall mean the earlier of (i) the date of exercise of
all of the rights represented by this Warrant and (ii) March 30, 2014.

e.	"Person" shall mean and include an individual, partnership, corporation,
trust, joint venture, incorporated organization and a government or any
department or agency thereof.

f.	"Securities Act" means the Securities Act of 1933, as amended.

g.	"Subject to Forfeiture" means that portion of this Warrant which has not
Vested and therefore may not be exercised.  If the Company is acquired in an
acquisition or takeover before April 15, 2008, all Warrant shares Subject to
Forfeiture shall become Vested at the Closing of the acquisition or takeover.
If the Company's convertible debt outstanding as of April 30, 2007 is refinanced
through the contacts of the Company's chairman rather than Bayberry Capital,
then 50% of this warrant shall be forfeited.

h.	"Vested" shall mean those Warrants which are fully owned by the Holder
and not Subject to Forfeiture.  These Warrants shall vest ratably on a monthly
basis over a 60-month term (i.e. 16,667 per month) commencing on April 26, 2007,
but shall Vest in full earlier if IFHR achieves $7.5 million in quarterly
revenue as reported in its periodic SEC filings and $720,000 in quarterly EBITDA
as reported in its periodic SEC filings and IFHR successfully refinances its
existing debt on terms suitable to IFHR's Chairman in his sole discretion.

i.	"Warrant Shares" shall mean the shares of Common Stock issuable to the
Holder of this Warrant upon any exercise of this Warrant.

2.	Warrant Exercise; Issuance of Certificates; Payment for Warrant Shares.
This Warrant may be exercised by the Holder to the extent Vested, in whole or in
part, at any time  prior to the Expiration Date by delivery of an Exercise
Notice and, within five (5) business days thereafter, surrender of this Warrant
(properly endorsed if required) and payment by the Holder of the Exercise Price
by certified or cashier's check.  Upon such surrender and payment, the Holder
shall be entitled to receive a certificate or certificates representing the
Warrant Shares so purchased.  Warrant Shares so purchased shall be deemed to be
issued to the Holder as the record owner of such Warrant Shares as of the close
of business on the date on which this Warrant shall have been surrendered and
payment made for such shares.  Certificates for the Warrant Shares so purchased
shall be delivered to the Holder within a reasonable time, not exceeding three
(3) business days, after the rights represented by this Warrant shall have been
so exercised.  If the rights of the Holder of this Warrant are exercised in
part, the number of Warrant Shares subject to this Warrant shall be reduced
accordingly and the Company shall reissue a Warrant or Warrants of like tenor
representing in the aggregate the right to purchase the number of Warrant Shares
as so reduced.

3.	Affirmative Covenants.  The Company covenants and agrees that the
Warrant Shares will, upon exercise of this Warrant and issuance in accordance
herewith, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issue thereof.  The
Company further covenants and agrees that until the Expiration Date, the Company
will at all times have authorized, and reserved for the purpose of issue upon
total or partial exercise of the rights represented by this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of
the rights represented by this Warrant.

4.	Adjustments.  If the Company shall, while this Warrant remains
outstanding, (a) pay a stock dividend or make a distribution to holders of
Common Stock in shares of its Common Stock, (b) subdivide its outstanding shares
of Common Stock, (c) combine its outstanding shares of Common Stock into a
smaller number of shares or (d) issue by reclassification of its shares of
Common Stock any shares of capital stock of the Company, then thereafter the
number of Warrant Shares shall be automatically (and without notice or further
action) increased or decreased, as the case may be, in direct proportion to the
increase or decrease in the number of shares of Common Stock by reason of such
change, and the per share Exercise Price of this Warrant after such change shall
in case of an increase in the number of shares be proportionately decreased, and
in case of a decrease in the number of shares be proportionately increased so
that the aggregate Exercise Price of this Warrant shall be unchanged by such
change.

5.	Reorganization, Reclassification, Share Exchange or Merger.

a.	If at any time prior to the Expiration Date the Company is a party to
any agreement providing for (i) any capital reorganization or reclassification
of the capital stock of the Company or (ii) any share exchange or merger of the
Company with another corporation, in such a way that holders of Common Stock
shall be entitled to receive cash, shares of stock or securities or assets
(collectively, and regardless of whether received in connection with a merger or
some other form of corporate reorganization, the "Merger Consideration") with
respect to or in exchange for Common Stock, then, as a condition to such
reorganization, reclassification, share exchange or merger, the Holder shall be
given the opportunity to elect to receive such cash, shares of stock or
securities or assets as may be issued or payable with respect to or in exchange
for the number of Warrant Shares then issuable upon the exercise of the rights
represented by this Warrant.

b.	If the Holder elects to receive the Merger Consideration, then upon
Holder's actual receipt of the Merger Consideration the Holder shall pay to the
Company (i) the per share Exercise Price of this Warrant multiplied by (ii) the
number of shares of Common Stock then issuable upon the exercise of the rights
represented by this Warrant, and thereafter the parties shall have no further
rights or obligations hereunder.

c.	If the Holder does not elect to receive the Merger Consideration, the
rights and obligations of the Holder and the Company (including any successor
company) under this Warrant shall remain in full force and effect pursuant to
the terms and conditions of this Warrant.  In any such case, the Company shall
not effect any such reclassification, reorganization, share exchange or merger,
unless prior to the consummation thereof the successor corporation (if other
than the Company) resulting from such share exchange or merger shall assume by
written instrument the obligation to deliver to the Holder, upon exercise of
this Warrant, such cash, shares of stock or securities or assets as the Holder
would have been entitled to receive had the Holder made the election in
accordance with the provisions of this Section.

d.	In connection with any capital reorganization or reclassification of the
capital stock of the Company or any share exchange or merger of the Company with
another corporation, if the Company shall fix a record date for the making of a
distribution to holders of Common Stock of (i) assets (other than cash dividends
or cash distributions payable out of consolidated net income or earned surplus
or dividends payable in Common Stock), (ii) evidences of indebtedness or other
securities of the Company, or of any corporation other than the Company (except
for the Common Stock of the Company) or (iii) subscription rights, options or
warrants to purchase any of the foregoing assets or securities, whether or not
such rights, options or warrants are immediately exercisable, to the extent such
rights, options or warrants have not expired, then the Company shall make
provisions for the Holder to receive, and the Holder shall be entitled upon
exercise of this Warrant to, a proportional amount (depending upon the extent to
which such Warrant is exercised) of such assets, evidences of indebtedness,
securities or such other rights, options or warrants, as if the Holder had
exercised this Warrant on or before such record date.

6.		Registration Rights.

a.		If the Company at any time or times proposes or is required to
register any of the Common Stock or other equity securities of the Company under
the Securities Act (other than on Forms S 4 or successor forms thereto), it will
at each such time or times give written notice to the Holder of its intention to
do so.  Upon the written request of the Holder given within five (5) days after
receipt of any such notice, the Company shall cause any Common Stock issuable to
the Holder upon exercise of this Warrant ("Registrable Securities") requested in
such notice to be registered (a "Piggyback Registration") under the Securities
Act and any applicable state securities laws.  With respect to each Piggyback
Registration, all fees, costs and expenses shall be borne by the Company.

b.		The Company shall take such measures and file such information,
documents and reports as shall hereafter be required by the Securities and
Exchange Commission (the "SEC") as a condition to the availability of Rule 144
under the Securities Act (or any corresponding or successor rule hereafter in
effect).  The Company covenants that all such information, documents and reports
or any registration statement required by Section 12 of the Securities Exchange
Act of 1934, as amended, filed with the SEC shall not contain any untrue
statement of a material fact or fail to state therein a material fact required
to be stated therein or necessary to make the statements contained therein not
misleading, and the Company agrees to indemnify and hold each seller of
Registrable Securities and each broker, dealer, underwriter or other person
acting for such seller (and any controlling person of any of the foregoing)
harmless from and against any and all claims, liabilities, losses, damages or
expenses and judgments arising out of or based upon any breach of the foregoing
covenants, representations or warranties.  If the Shell reorganizes,
consolidates or merges with or into any person or entity, the Company shall make
provision for the rights of the Holder and obligation of the Company with
respect to Shell Common Stock pursuant to this Section to be assumed by the
Shell.

c.	The Company shall register the shares underlying this warrant on Form
S-8 by July 31, 2007 unless prohibited by law from doing so.

7.	Term of Warrant.  This Warrant shall remain outstanding and exercisable
until the Expiration Date.  To the extent not previously exercised, the rights
represented by this Warrant shall thereupon terminate.

8.	Issue Tax.  The issuance of certificates for shares of Common Stock upon
the total or partial exercise of this Warrant shall be made without charge to
the Holder for any issuance tax in respect thereof.

9.	Closing of Books.  The Company will at no time close its transfer books
in any manner which interferes with the timely exercise of the rights
represented by this Warrant.

10.	No Voting Rights.  This Warrant shall not entitle the Holder to any
voting rights as a shareholder of the Company.

11.	Notices.  All notices and communications provided for herein or made
hereunder shall be delivered, or mailed first class with postage prepaid, or
faxed, addressed in each case as follows, until some other address shall have
been designated in a written notice given in like manner, and shall be deemed to
have been given or made when so delivered or mailed or faxed:

		(a) if to the Company:

		INFe-Human Resources
		Attn:  Chairman of the Board
		67 Wall Street, 22nd Floor
		New York, NY 10005

		(b) if to the Holder:

		Jay O. Wright
		Fax:  301.610.2094

		or to such other person or address as the party entitled to
		notice hereunder shall designate by notice in accordance with
		this Warrant.

12.	Replacement of Warrant.  Upon receipt of evidence satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant, and upon
receipt of written indemnification of the Company by the Holder in form and
substance satisfactory to the Company, the Company shall execute and deliver to
the Holder a new Warrant of like date, tenor and denomination.

13.		Miscellaneous.

a.		This Warrant may be amended only by a writing signed by the
Company and the Holder.  All covenants and agreements in this Warrant by the
Company shall bind its successors and assigns.

b.		In case any provision in this Warrant shall be invalid, illegal
or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

c.		This Warrant shall be governed by and construed in accordance
with the laws of the State of New York without regard to the principles of
conflicts of laws thereof.

d.		This Warrant constitutes the full and entire understanding
between the Company and the Holder with respect to the subject matter hereof.

e.		Failure of, or delay by, the Holder to assert any right herein
shall not be deemed to be a waiver thereof, nor shall any such failure or delay
on any one or more occasions be deemed to prohibit or waive the same or any
other right on any future occasion.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed
as of the date first written above.
