RE:          Bridge Financing by Global Project Finance AG

Attention Christian Russenberger,

This letter will confirm recent discussions relative to bridge financing by
Global Project Finance AG in the total amount of $250,000.  The bridge
financing, among other things, would be on the terms set forth below:

1.     Financing. Global Project Finance AG (“Lender”) will provide bridge
financing in the form of a loan in the total amount of $250,000 to VitaCube
Systems Holdings, Inc., d/b/a XELR8 Holdings, Inc. (“VitaCube”), a Nevada
corporation. $250,000 will be loaned to VitaCube on or before January 10, 2007
(the “Loan”).

2.     Terms. The Loan will accrue interest at ten percent (10%) per annum from
the date of funding with all principal and accrued but unpaid interest due upon
the earlier of (i) the closing of the VitaCube current private placement
offering of a minimum of $1,000,000 and a maximum of $3,000,000 (the “Private
Placement”) or (ii) six (6) months from the date of the Funding. If the Private
Placement does not close prior to six (6) months form the date of the Funding,
all principal and accrued but unpaid interest shall be paid in restricted shares
of VitaCube common stock at a price equal to fifty percent (50%) of the thirty
(30) day trailing closing price of VitaCube common stock.

3.     Stock Issuance.  As a loan fee and in addition to any shares of common
stock that may be issued in accordance with Section 2 above, VitaCube agrees,
upon the Final Funding, to issue 400,000 restricted shares of its common stock
(the “Loan Shares”) to Lender with an appropriate legend placed on the
certificate representing such shares. All Loan Shares shall have “piggy-back”
registration rights with any shares of the Private Placement that are registered
and all costs associated with the registration of the Loan Shares shall be paid
by VitaCube.

4.     Loan Documents.  The Loan shall be evidenced by a promissory note and
Lender shall execute a normal and customary Subscription Agreement and Letter of
Investment Intent regarding the Loan Shares.

5.               Representations of VitaCube. VitaCube represents and warrants
to Lender that:

(a)          VitaCube is in good standing as corporation in the State of Nevada
and is not aware of any violation of any Federal or State securities laws.

(b)         VitaCube is current as to all tax, securities, or other regulatory
filings, and VitaCube will make all necessary filings with the SEC subsequent to
the closing of the Loan.

--------------------------------------------------------------------------------

 

(c)          At the closing of the Loan, there will have been no changes in the
capital structure of VitaCube other than those necessary to conform to the terms
of this Letter of Intent.

(d)         VitaCube will take all necessary steps to have its board of
directors approve the terms of this Letter of Intent.

6.     Acknowledgment of Due Diligence. Lender acknowledges that it has had full
access to VitaCube’s books and records and financial and operating data and such
other information with respect to VitaCube’s business and assets as it has
determined necessary for purposes of conducting an appropriate due diligence
investigation.  Lender and its representatives shall keep confidential all
information (unless ascertainable from public findings or published information)
obtained concerning the VitaCube’s operations, assets and business, use it only
for the purposes stated herein, and promptly return or destroy it if the
proposed transaction is not consummated.

7.     Press Release. Both parties will cooperate in preparing a press release
describing the Loan.  The press release will be submitted for release once the
Initial Funding is made, unless legal counsel advises that for compliance
purposes it must be released sooner or later.  Except for this release, neither
party hereto shall release any information to the public or the media without
the consent of the other party until the Closing.

Upon the execution by you and return to us of this Letter of Intent, the terms
of this Letter of Intent, subject to approval by the VitaCube board of
directors, shall be binding on all parties. The Note shall contain provisions in
accordance with this Letter of Intent together with such other terms and
conditions as legal counsel and the parties may mutually determine and agree.

If the terms of this Letter of Intent are acceptable, please execute this Letter
of Intent below and return a signed copy to me. Thank you.

Vita Cube Systems Holdings, Inc.
