BRIDGE LOAN AGREEMENT

THIS BRIDGE LOAN AGREEMENT (this “Agreement”) is made this 31^st day of March, 2008, by and among Single Touch Interactive, Inc., a Nevada corporation (“Borrower”), and Hosting Site Network, Inc., a Delaware corporation (“Lender”).

W I T N E S S E T H:

WHEREAS, Lender and Borrower have agreed upon certain of the terms and conditions of a merger (the “Merger”) and related transactions (collectively, the “Transactions”) which is expected to be completed and closed upon no later than May 31, 2008 (the “Completion Date”);

WHEREAS, simultaneously herewith Lender is engaged in an offering (the “Note Offering”) of its 12% Convertible Promissory Notes, which offering is being conducted pursuant to the exemption from registration provided by Rule 506 of Regulation D, Regulation S and/or Section 4(2) under the Securities Act of 1933, as amended (the “Securities Act”); and

WHEREAS, to provide Borrower with additional working capital to enable Borrower to fulfill certain obligations incident to its business while Lender and Borrower prepare the documentation necessary and appropriate to consummate the Transactions and obtain all necessary approvals from stockholders and third parties, Lender has agreed to utilize the net proceeds of the Note Offering to provide Borrower with a temporary loan in the principal amount equal to the net proceeds of the Note Offering.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Borrower and Lender, intending to be legally bound, agree as follows:

ARTICLE I - LOAN

1.1. Loan. Lender agrees, on the terms and conditions of this Agreement, to make periodic loans to Borrower in the amount of up to Three Million Dollars Three Hundred Thousand ($3,300,000) (the “Loans”) commensurate with the net proceeds received by Lender in the Note Offering.

1.2. The Note. Borrower has authorized the issuance of promissory notes (each, a “Note” and collectively the “Notes”) made in favor of Lender by Borrower, which shall be in the form set forth in Exhibit A attached hereto. Each disbursement of the Loan shall bear interest at the rate of 12 percent (12%) per annum, and shall be due and payable to the order of Lender on the Completion Date, unless extended by Lender and Borrower in writing; provided, however, that from and after an Event of Default, as defined in Article IV hereof, such interest rate shall increase to eighteen percent (18%) per annum.

1.3. Payments. Principal and accrued interest payable on the Notes is due on the Completion Date; provided, however, that upon the closing of the Merger on or prior to the Completion Date, all amounts outstanding under the Loans shall be forgiven, and the Notes shall be cancelled and deemed repaid in full.

In the event the Merger is not completed by the Completion Date due to the actions of Borrower acting without cause, the Lender shall have the right, at its sole discretion, to cause Borrower to convert the amount of principal and interest then due under the Notes, in whole or in part, into units of Borrower at a price of $1.25 per unit, each unit consisting of one share of Borrower’s common stock, one Class A Warrant to purchase one share of Borrower’s common stock at a price of $1.60 per share at any time during a period of 18 months from issuance, and one Class B Warrant to purchase one share of Borrower’s common stock at a price of $2.05 per share at any time during a period of 36 months from issuance.

In the event the Merger is not completed by the Completion Date due to the actions of Lender acting without cause (the “Lender Action”), the Borrower shall have the right to seek appropriate legal remedies against Lender. These remedies will not relieve Borrower of its obligations under the Notes. Notwithstanding the foregoing and any other provisions of this Agreement, in such event, Borrower will be relieved of its obligation to pay interest under the Notes but must pay back all principal due under the Notes within sixty (60) days of the Completion Date.

1.4. Security for Loan. The Loan will be secured by Borrower’s assets as set forth in the Security Agreement among Borrower and Lender in the form attached hereto as Exhibit B.

ARTICLE II - REPRESENTATIONS AND WARRANTIES OF BORROWER

Borrower represents and warrants to Lender as follows:

2.1. Organization. Borrower is a corporation duly existing under the laws of its jurisdiction of incorporation and qualified and licensed to do business in any jurisdiction in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to be so qualified would not have a material adverse effect on the business, operations, condition (financial or otherwise), property or prospects of Borrower (as defined below), or the ability of Borrower to carry out its obligations under the Loan Documents (as defined in Section 2.3 below) (a “Company Material Adverse Effect”).

2.2. Subsidiaries. Borrower has no subsidiaries. For purposes of this Agreement, a “Subsidiary” means any corporation, partnership, joint venture or other entity in which Borrower has, directly or indirectly, an equity interest representing 50% or more of the capital stock thereof or other equity interests therein.

2.3. Authorization. All corporate action on the part of Borrower and its officers, directors and stockholders necessary for the authorization, execution, delivery and performance of all obligations of Borrower under this Agreement, the Note, the Security Agreement and all other documents executed in connection with the Loan (collectively, the “Loan Documents”) to which any of them may be a party have been taken. This Agreement, the Note, the Security Agreement and the other Loan Documents, when executed and delivered by Borrower, shall constitute legal, valid and binding obligations of Borrower, enforceable against Borrower in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium or similar laws affecting creditors’ rights and the enforcement of debtors’ obligations generally and by general principles of equity, regardless of whether enforcement is pursuant to a proceeding in equity or at law.

2.4. Absence of Conflicts. The execution, delivery and performance of this Agreement and each of the other Loan Documents is not in conflict with nor does it constitute a breach of any provision contained in Borrower’s organizational documents, nor will it constitute an event of default under any material agreement to which Borrower is a party or by which Borrower is bound.

2.5. Consents and Approvals. Borrower has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities and agencies that are necessary for the continued operation of Borrower’s business as currently conducted, or are required by law.

2.6. Capitalization. The authorized and outstanding capital stock of Borrower is described in the Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) among Lender, Borrower and Single Touch Acquisition Corp. dated as of March 20, 2008. Except as set forth in the Merger Agreement or as contemplated by the Transactions, there are no subscriptions, convertible securities, options, warrants or other rights (contingent or otherwise) currently outstanding to purchase any of the authorized but unissued capital stock of Borrower. Except as set forth in the Merger Agreement or as contemplated by the Transactions, Borrower has no obligation to issue shares of its capital stock, or subscriptions, convertible securities, options, warrants, or other rights (contingent or otherwise) to purchase any shares of its capital stock or to distribute to holders of any of its equity securities, any evidence of indebtedness or asset. No shares of Borrower capital stock are subject to a right of withdrawal or a right of rescission under any applicable securities law. Except as set forth in the Merger Agreement, there are no outstanding or authorized stock appreciations, phantom stock or similar rights with respect to Borrower. To the Knowledge (as defined below) of Borrower, except as described in the Merger Agreement or otherwise contemplated by this Agreement, there are no agreements to which Borrower is a party or by which it is bound with respect to the voting (including without limitation voting trusts or proxies), registration under any applicable securities laws, or sale or transfer (including without limitation agreements relating to pre-emptive rights, rights of first refusal, co-sale rights or “drag-along” rights) of any securities of Borrower. Except as provided in the Merger Agreement, to the Knowledge of Borrower, there are no agreements among other parties, to which Borrower is not a party and by which it is not bound, with respect to the voting (including without limitation voting trusts or proxies) or sale or transfer (including without limitation agreements relating to rights of first refusal, co-sale rights or “drag-along” rights) of any securities of Borrower.

2.7. Litigation. There are no actions, suits, claims, investigations, arbitrations or other legal or administrative proceedings, to the Knowledge of Borrower, threatened against Borrower at law or in equity, and to Borrower’s Knowledge, there is no basis for any of the foregoing. There are no unsatisfied judgments, penalties or awards against or affecting Borrower or its businesses, properties or assets. Borrower is not in default, and no event has occurred which with the passage of time or giving of notice or both would constitute a default by Borrower with respect to any order, writ, injunction or decree known to or served upon Borrower of any court or of any foreign, federal, state, municipal or other governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign. There is no action or suit by Borrower pending or threatened against others. Borrower has complied with all laws, rules, regulations and orders applicable to its current business, operations, properties, assets, products and services the violation of which would have a Company Material Adverse Effect. There is no existing law, rule, regulation or order, and Borrower has no Knowledge of any proposed law, rule, regulation or order, whether foreign, federal or state, that would prohibit or materially restrict Borrower from, or otherwise materially adversely affect Borrower in, conducting its businesses in any jurisdiction in which it is now conducting business.

As defined in this Agreement, “Knowledge” of Borrower means the actual knowledge by a director or officer of Borrower of a particular fact or circumstance or such knowledge as may reasonably be imputed to such person as a result of such person’s actual knowledge of other facts or circumstances as well as any other knowledge which such person would have possessed had such person made reasonable inquiry of appropriate employees and agents of Borrower with respect to the matter in question.

2.8. Absence of Certain Events. To Borrower’s Knowledge, there is no existing condition, event or series of events which reasonably would be expected to have a Company Material Adverse Effect.

2.9. Title to Property and Assets. Borrower does not own any real property. Borrower has good and marketable title to all of its personal property and assets free and clear of any material restriction, mortgage, deed of trust, pledge, lien, security interest or other charge, claim or encumbrance which would have a Company Material Adverse Effect. With respect to properties and assets it leases, Borrower is in material compliance with such leases and holds a valid leasehold interest free of any liens, claims or encumbrances which would have a Company Material Adverse Effect.

2.10. Governmental Permits. Borrower holds all licenses, franchises, permits and other governmental authorizations which are required for the conduct of any aspect of Borrower’s business, as presently conducted and as presently contemplated to be conducted, including, but not limited to, all such business operations contemplated by, or incident to, the Transactions. All such licenses, franchises, permits and other governmental authorizations are valid and current, and Borrower has not received any notice that any governmental authority intends to cancel, terminate or not renew any such license, franchise, permit or other governmental authorization. Borrower has conducted and is conducting its business in material compliance with the requirements, standards, criteria and conditions set forth in such licenses, franchises, permits and other governmental authorizations, and all laws and regulations applicable thereto, and is not in violation of any of the foregoing. The consummation of the transactions contemplated hereunder will not alter or impair or require changes to any such license, franchise, permit or other governmental authorization.
