                              X-CHANGE CORPORATION
                       IRREVOCABLE SUBSCRIPTION AGREEMENT
                               FEBRUARY-MARCH 2007

1.       SUBSCRIPTION. Subject to the terms and conditions hereof, the
         undersigned (hereinafter referred to as the "SUBSCRIBER") irrevocably
         tenders this "Subscription" and hereby subscribes for the number of
         Units (as defined in the Offering Memo) set forth on the signature page
         hereto as described in the Confidential Private Placement Memorandum
         attached hereto as EXHIBIT A (the "OFFERING MEMO").

2.       ACCEPTANCE OF SUBSCRIPTION. This Subscription Agreement shall not
         become binding unless (i) this Subscription Agreement is accepted by
         the Company, (ii) the Subscription Amount has been received and
         accepted by the Company, and (iii) such additional closing conditions
         as the Company, in its sole discretion, shall require are satisfied.
         This Subscription shall not be deemed accepted by the Company until
         this Subscription Agreement is signed by a duly authorized officer of
         the Company and returned to Subscriber. If this Subscription is
         accepted, this Subscription Agreement shall become effective as between
         the Company and the Subscriber. If this Subscription is rejected, this
         Subscription Agreement and the Subscription Amount will be returned to
         the Subscriber as soon as reasonably practicable, and this Subscription
         shall be rendered void and of no further force or effect.

3.       ANCILLARY DOCUMENTS. In connection with its subscription, Subscriber
         has executed and delivered the Registration Rights Agreement in the
         form attached hereto as EXHIBIT B (which the Company will counter-sign
         and deliver to Subscriber if it agrees to accept Subscriber's
         subscription) and the Confidentiality Agreement in the form attached
         hereto as EXHIBIT C.

4.       REPRESENTATIONS AND WARRANTIES OF SUBSCRIBER. Subscriber hereby
         represents and warrants to the Company as follows:

         A. The Subscriber is an "accredited investor" (as defined on EXHIBIT D
         hereto) and is domiciled in the state indicated on the signature page
         hereto.

         B. The Securities hereby subscribed for are being acquired by
         Subscriber as the ultimate owner, in good faith, for Subscriber's own
         account, not as a conduit, underwriter, nominee or agent for other
         beneficial or subsequent owners, and not with a view to the resale or
         distribution of any part thereof; Subscriber has no present intention
         of selling, granting any participation in, or otherwise distributing
         the same and has no contract, undertaking, agreement or arrangement
         with any person to transfer, encumber, or grant participations to any
         person, with respect to any of the Securities. The Subscriber warrants
         that any funds which may be tendered for the purchase of Securities
         will not represent funds borrowed by the Subscriber from any person or
         lending institution except to the extent that the Subscriber has a
         source for repaying such funds other than from the sale of the
         Securities subscribed, and that such Securities have not been pledged
         or otherwise hypothecated for any such borrowing.

         C. Subscriber has received and carefully reviewed a copy of the
         Offering Memo and agrees that it, along with all information regarding
         the Company that is publicly available, supersedes any offering memos
         or other materials that the Company previously provided to Subscriber,
         if any.

         D. Subscriber acknowledges that he has been advised that the Securities
         have not been registered under the Act, as amended, or under the
         provision of any state securities laws, on the grounds that the offer
         and sale of the Securities is exempt from registration under the
         provisions of those Statutes as not involving any public offering.

         E. Subscriber acknowledges that the Subscriber has had the reasonable
         opportunity to ask questions and receive answers concerning the
         offering of the Securities and to obtain additional information
         necessary to verify the accuracy of the information furnished in the
         Offering Memo.

                                      -1-

4.       SUCCESSORS AND ASSIGNS. The Subscriber agrees that this Subscription
         Agreement shall be binding upon and inure to the benefit of all the
         parties hereto and their respective heirs, legal representatives,
         successors and assigns.

5.       INDEMNIFICATION. Subscriber understands and is aware of the
         significance to the Company of the foregoing representations,
         agreements and consents, and they are made with the intention that the
         Company may rely upon them. Subscriber acknowledges that he understands
         the meaning and legal consequences of the representations and
         warranties herein, and he hereby agrees to indemnify and hold harmless
         the Company and its officers, affiliates, agents and employees of the
         Company, and the persons who have solicited this subscription, from and
         against any and all loss, damage or liability, including but not
         limited to legal fees and court costs, due to or arising out of a
         breach of any such representations or warranties made by the
         Subscriber.

7.       NUMBER AND GENDER. Whenever the singular number is used in this
         Subscription Agreement and when required by the context, the same shall
         include the plural, and the masculine gender shall include the feminine
         and neuter genders.

9.       APPLICABLE LAW. This Subscription Agreement shall be governed by, and
         construed in accordance with, the laws of the State of Texas, without
         regard to principles of conflicts of laws. Any dispute under this
         Subscription Agreement that is not settled by mutual consent shall be
         finally adjudicated by any federal or state court sitting in Dallas
         County or Collin County, Texas, and each party consents to the
         exclusive jurisdiction of such courts (or any appellate court
         therefrom) over any such dispute. Each party further consents to
         personal jurisdiction in the courts mentioned in the prior sentence. In
         the event that any suit or action is instituted to enforce any
         provision in this Subscription Agreement, the prevailing party in such
         dispute shall be entitled to recover from the losing party all fees,
         costs and expenses of enforcing any right of such prevailing party
         under or with respect to this Subscription Agreement, including without
         limitation, such reasonable fees and expenses of attorneys and
         accountants, which shall include, without limitation, all fees, costs
         and expenses of appeals.

EXHIBIT 10.2

                              X-CHANGE CORPORATION
                          REGISTRATION RIGHTS AGREEMENT

         This REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT"), dated as of
___________________ ___, 2007, is among X-CHANGE CORPORATION, a Nevada
corporation (the "COMPANY"), and ________________________ each of the purchasers
of the Company's common stock (the "COMMON STOCK") and warrants to purchase
shares of Common Stock (the "WARRANTS") listed on EXHIBIT A hereto (the
"PURCHASER").

                                R E C I T A L S:

         A. WHEREAS, the Purchasers are acquiring or have acquired the shares of
Common Stock listed on EXHIBIT A (the "SHARES") and the Warrants listed on
EXHIBIT A pursuant to a private placement offering by the Company;

         B. WHEREAS, the Company desires to grant to the Purchasers certain
registration rights relating to the Shares and the shares of Common Stock
issuable upon exercise of the Warrants (the "WARRANT SHARES") and the Purchasers
desire to obtain such registration rights, subject to the terms and conditions
set forth herein;

         C. NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties set forth in this Agreement, the parties hereto,
intending to be legally bound, hereby agree as follows:

                               A G R E E M E N T:

         In consideration of the foregoing promises and the mutual covenants
contained herein, the sufficiency of which is hereby acknowledged, the parties
hereby agree as follows:

SECTION 1. REGISTRATION OF THE REGISTRABLE SECURITIES; COMPLIANCE WITH THE
SECURITIES ACT.

         1.1 REGISTRATION PROCEDURES. The Company is obligated to do the
following:

                  (a) The Company shall prepare and, within 120 days of the date
hereof, file with the Securities and Exchange Commission (the "SEC") a
registration statement on the appropriate form (the "REGISTRATION STATEMENT") in
order to register with the SEC the resale by the Holders (as defined below),
from time to time, of the Registrable Securities (as defined below). The Company
shall use commercially reasonable efforts to cause such Registration Statement
to be declared effective as soon as is reasonably possible following filing with
the SEC. The Company shall promptly notify the Holders of the effectiveness of
the Registration Statement. The holders of Registrable Securities (including a
Purchaser's permitted transferees hereunder) are referred to herein as the
"HOLDERS." "REGISTRABLE SECURITIES" shall mean (i) the Shares and the Warrant
Shares and (ii) Common Stock issued as (or issuable upon the conversion of
exercise of any warrant, right or other security that is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of
the Shares or the Warrant Shares; provided, however, such Shares, Warrant Shares

<PAGE>

and Common Stock shall cease to be considered Registrable Securities hereunder
on the earlier of such date as they sold pursuant to the Registration Statement
or are eligible to be sold pursuant to Rule 144(k) promulgated pursuant to the
Securities Act of 1933, as amended (the "SECURITIES ACT").

                  (b) The Company agrees to use commercially reasonable efforts
to keep such Registration Statement effective until the earliest to occur of the
following:

                           (i) The date that all Registrable Securities have
been sold pursuant to the Registration Statement;

                           (ii) Six months after all the Warrants are exercised
or deemed exercised (including a forced net exercise pursuant to Section 1(b)
thereof by the Company) pursuant to any provision included therein;

                           (iii) The date all Shares and Warrant Shares have
ceased to be considered Registrable Securities within the definition thereof;

PROVIDED, HOWEVER, that at any time, upon written notice to the Purchasers and
for a period not to exceed fifteen (15) calendar days thereafter (the
"SUSPENSION PERIOD"), the Company may delay the filing or effectiveness of any
Registration Statement or suspend the use or effectiveness of any Registration
Statement (and the Holders hereby agree not to offer or sell any Registrable
Securities pursuant to such Registration Statement during the Suspension Period)
if the Company reasonably believes that the Company may, in the absence of such
delay or suspension hereunder, be required under state or federal securities
laws to disclose any corporate development the disclosure of which could
reasonably be expected to have an adverse effect upon the Company, its
stockholders, a potentially significant transaction or event involving the
Company, or any negotiations, discussions, or proposals directly relating
thereto. The Company may extend the Suspension Period for an additional
consecutive fifteen (15) calendar days upon written notice to the Holders. The
Company agrees to use its commercially reasonable efforts to ensure that the
Suspension Period is kept to a minimum number of days. If so directed by the
Company, each Holder shall use its best efforts to deliver to the Company (at
the Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus relating to such Registrable Securities
current at the time of receipt of such notice.

                  (c) The Company shall furnish to the Holders such number of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                  (d) The Company shall use its best efforts to register and
qualify the securities covered by such Registration Statement under such other
securities or Blue Sky laws of such domestic jurisdictions as shall be
reasonably requested by a Holder; PROVIDED that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do
business or to file a general consent to service of process in any such states
or domestic jurisdictions, unless the Company is already subject to service in
such jurisdiction and except as required by the Securities Act.

                                      -2-

<PAGE>

                  (e) The Company shall notify each Holder whose Registrable
Securities are covered by such Registration Statement at any time when a
prospectus relating thereto is required to be delivered under the Securities Act
of the happening of any event as a result of which the prospectus included in
such Registration Statement, as then in effect, includes an untrue statement of
a material fact or omits to state a material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing. The Company shall use reasonable efforts to
promptly amend or supplement such prospectus in order to cause such prospectus
not to include any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing. During
any such period, the Holders shall not dispose of their Registrable Securities
pursuant to the Registration Statement.

         1.2 TRANSFER OF SECURITIES. Each holder of the Shares and each Holder,
severally and not jointly, agrees that it will not effect any disposition of the
Registrable Securities or the Warrants that would constitute a sale within the
meaning of the Securities Act, unless (a) pursuant to a registration statement
then in effect covering such disposition, if such disposition is made in
accordance with such registration statement; or (b) such Holder shall have
notified the Company of the proposed disposition and shall have furnished the
Company with a reasonably detailed statement of the circumstances surrounding
the proposed disposition, and if reasonably requested by the Company, such
Holder shall have furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, or other evidence, reasonably satisfactory to the
Company, that such disposition will not require registration of such Registrable
Securities under the Securities Act.

         1.3 TRANSFER OF REGISTRATION RIGHTS. Any Holder may transfer its rights
hereunder if:

                  (a) such transfer is made in connection with, and to the
extent of, a transfer of Registrable Securities;

                  (b) the Company is given written notice prior to said transfer
or assignment, stating the name and address of the transferee or assignee and
identifying the Registrable Securities that are intended to be transferred or
assigned;

                  (c) the transferee or assignee of such rights delivers to the
Company, in a form reasonably acceptable to the Company, an agreement evidencing
the assumption of all of the rights and obligations of such Holder under this
Agreement; and

                  (d) such transferee or assignee is:

                           (i) a partner, retired partner, member, retired
member or affiliate of the
Holder; or

                           (ii) an Immediate Family Member of such Holder.

"IMMEDIATE FAMILY MEMBER" means a spouse and lineal antecedents and descendants,
including by marriage or adoption, and trusts or family partnerships or limited
liability companies controlled by any of the foregoing and exclusively for the
benefit of any of the foregoing.

                                      -3-

<PAGE>

         1.4 LEGENDS. Each certificate representing the Shares and the Warrants
shall (unless otherwise permitted by the provisions of the Agreement) be stamped
or otherwise imprinted with a standard legend regarding restrictions under
applicable securities laws.

         1.5 EXPENSES OF REGISTRATION. Except as specifically provided herein,
all expenses incurred by the Company in complying with SECTION 1 hereof,
including, all registration and filing fees, printing expenses, fees and
disbursements of counsel for the Company, blue sky fees and expenses, fees and
the expense of any special audits incident to or required by any such
registration (but excluding the compensation of regular employees of the Company
which shall be paid in any event by the Company) shall be borne by the Company.
All underwriting discounts and brokerage/selling commissions applicable to a
sale incurred in connection with any registrations hereunder shall be borne by
the holders of the securities so registered PRO RATA on the basis of the number
of shares registered for resale.

         1.6 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this SECTION 1.

                  (a) The Company will indemnify and hold harmless each Holder,
the partners, officers and directors of each Holder, any underwriter (as defined
in the Securities Act) for such Holder and each person, if any, who controls
such Holder or underwriter within the meaning of the Securities Act or the
Exchange Act, against any losses, claims, damages, or liabilities (joint or
several) to which they may become subject under the Securities Act, the Exchange
Act or other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"VIOLATION"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law in connection with the offering covered by such
registration statement; and the Company will pay as incurred to each such
Holder, partner, officer, director, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 1.6
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld, nor shall the Company
be liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished specifically
for use in connection with such registration by such Holder, partner, officer,
director, underwriter or controlling person of such Holder.

                                      -4-

<PAGE>

                  (b) Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which registration, qualifications
or compliance is being effected, indemnify and hold harmless the Company, each
of its directors, its officers and each person, if any, who controls the Company
within the meaning of the Securities Act, any underwriter and any other Holder
selling securities under such registration statement or any of such other
Holder's partners, directors or officers or any person who controls such Holder,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, underwriter or
other such Holder, or partner, director, officer or controlling person of such
other Holder may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder specifically for use in connection with such
registration; and each such Holder will pay as incurred any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other person registering shares under such
registration, or partner, officer, director or controlling person of such other
person registering shares under such registration in connection with
investigating or defending any such loss, claim, damage, liability or action;
PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 1.6
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of such
Holder, which consent shall not be unreasonably withheld; PROVIDED FURTHER, that
in no event shall any indemnity under this Section 1.6 exceed the net proceeds
from sale of Registrable Securities pursuant to the Registration Statement
received by such Holder (i.e., gross proceeds less discounts and commissions).

                  (c) Promptly after receipt by an indemnified party under this
Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to retain its own counsel, with the reasonable and actual fees
and expenses to be paid by the indemnifying party, if representation of such
indemnified party by the counsel retained by the indemnifying party would be
inappropriate due to actual or potential differing interests between such
indemnified party and any other party represented by such counsel in such
proceeding. The failure to deliver written notice to the indemnifying party
within a reasonable time of the commencement of any such action, if materially
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.6, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.6.

                  (d) If the indemnification provided for in this Section 1.6 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
