Exhibit 10.6

THE PLANET

Master Services Agreement

This Master Services Agreement (“MSA”) is entered into by ThePlanet.com Internet Services, Inc., a Delaware corporation (“Planet”) and the below-signed customer (“Customer”), a Florida limited liability company, on the date Customer signs the MSA (“Effective Date”). The term “Agreement” shall refer to the following agreements (including any amendments thereto) between Planet and Customer: the MSA, the Service Exhibit attached hereto, any applicable server order forms, Planet’s Acceptable Use Policy (posted on www.theplanet.com, the “AUP”), and any applicable Planet service level agreement agreed to by the parties hereto,

1. Services. Planet agrees to provide the hosting and network services as provided for in, and subject to the terms of, the Agreement (“Services’’) beginning on the date that Planet submits to Customer access codes to use the Services or when otherwise provided for in the Service Exhibit attached hereto (“Commencement Date”). Planet may perform additional technical, supplemental, or professional services for Customer at either Planet’s published pricing rates or at rates mutually agreed to between Customer and Planet. Also, Planet may perform remedial services as provided for in the AUP at the pricing set forth therein and without obtaining Customer’s consent In advance.

With respect to each hosted server for which Services are provided to Customer by Planet and which is specifically identified by a unique IP address and hardware code identifier used internally by Planet (a “Server”), Planet will not engage in any price increases with respect to any Server during the first [**] months after the Effective Date of this MSA and will be entitled to engage in price increases of the original price of such Server provided that same do not exceed [**]% of the original price during any [**] month period, and further do not exceed on a cumulative basis [**]% of the original price over the entire time period during which Services are provided to Customer for such Server. Such price protection will apply with respect to each Server on an individual basis.

2. Payment. Customer agrees to pay the charges in US dollars for the Services, and for any additional services described herein, as set forth in the Agreement (collectively, “Charges”). Except as otherwise provided for herein, Charges shall be invoiced to Customer in advance (but may include any applicable pro-rated amounts for incomplete months of Service provision) and shall be due and payable upon receipt. Any additional one-time charges, including early cancellation charges, accrued interest, late fees, service reinstatement fees, and any usage-based charges (e.g., Internet access) shall be invoiced in arrears and appear on either regular monthly invoices or separate invoices. Customer also shall pay to Planet all expenses incurred by Planet in exercising any of its rights under this Agreement or applicable law with respect to the collection of a Payment Default, including attorneys’ fees, court costs, and collection agency fees. Planet may charge interest on any invoice amounts that are overdue by more than [**] days at the lesser of (a) [**]% per month or (b) the maximum non-usurious rate under applicable law. Customer shall be deemed to have accepted as conclusively accurate any invoice that it has not disputed in a writing delivered to Planet within [**] months of the invoice date. In the event that

this Agreement is terminated by Planet for any reason constituting “Planet Termination” (as that term is defined below) or by Customer for any reason other than “Customer Termination” (as that term is defined below), all Charges under the Agreement, including all remaining monthly fees due for the remaining portion of the Initial Term and any applicable Renewal Period, are immediately due and payable.

3. Term and Termination. As long as Customer has never ordered in any month during the Initial Term or any Renewal Period (as defined herein) less than the Minimum Monthly Charges (as that term is defined in the Service Exhibit attached hereto), the initial term (“Initial Term”) of the Agreement shall be two (2) years, commencing on the Commencement Date. Unless the Agreement is earlier terminated, as provided for herein, and as long as Customer has never ordered in any month during the Initial Term or any Renewal Period less than the Minimum Monthly Charges, the Initial Term shall automatically renew for successive terms of ninety (90) days (each, a “Renewal Period”). Either party may terminate this Agreement for any reason by delivering to the other party a written notice of non-renewal thirty (30) days prior to the termination of the Initial Term or any active Renewal Period.

Notwithstanding the foregoing, Planet may immediately terminate this Agreement at any time, and without liability, upon the occurrence of any of the following (“Planet Termination”): (i) Customer’s failure to pay any overdue invoice amount upon written or email notice by Planet or (ii) Customer’s material breach or violation of any provision of the Agreement that is not cured within [**] days of Customer’s receipt of written notice from Planet referencing such breach or violation; (iii) Customer ceasing to do business in the normal course, becoming or being declared insolvent or bankrupt, being the subject of any proceeding relating to liquidation or insolvency which is not dismissed within ninety (90) calendar days, or making an assignment for the benefit of its creditors; (iv) Customer’s failure to cure any violation of the AUP within a reasonable amount of time; or (v) Planet determines in its sole discretion that Customer is continues to host content, despite being given a reasonable amount of time by Planet to remove such content, that may subject Planet to legal liability (in which case, Planet may also modify the Service to

avoid such liability).

Customer may terminate this Agreement with respect to all, and not less than all, of the Services without liability (except for Charges due through the effective date of such termination) upon the occurrence of a material breach by Planet of its obligations to provide the Services according to the terms of the Agreement that is not cured within [**] business days after written notice from Customer describing the such breach in detail is received by Planet (“Customer Termination”). In the event of a Customer Termination, Customer shall pay (i) any outstanding installation Charges, (ii) a pro-rated Charge based on the number of days Planet provided Services prior to the date of Customer Termination, and (iii) if the Services include software for which Planet does not then provide general customer support, Customer shall pay to Planet an amount equal to Planet’s cost of such software for the entire Initial Term and any applicable Renewal Periods. If Customer terminates this Agreement for any reason other than a Customer Termination, Customer shall pay to Planet an amount equal to all unpaid Charges for the remainder of the then current term of this Agreement.

Upon termination of this Agreement, Planet and Customer shall have no obligations to each other, except as provided for in this Agreement. Upon termination of this Agreement, Customer shall (i) pay all Charges and other amounts due and owing to Planet, (ii) remove from Planet’s premises all property owned by Customer, and (iii) return to Planet all software, access keys, and any other property provided to Customer by Planet under this Agreement. Any property of Customer not removed from Planet’s premises within [**] days after such termination shall become the property of Planet, which may, among other things, dispose of such property without the payment of any compensation to Customer. The rights and obligations of both parties, which by their nature would continue beyond the termination of this Agreement (including, those relating to confidentiality, payment of outstanding Charges, limitations of liability and indemnification), shall survive such termination.

Notwithstanding the foregoing, as long as Customer has never ordered in any month during the Initial Term or any Renewal Period less than the Minimum Monthly Charges, in the event that Planet permanently terminates and deactivates the Services or any portion thereof in a manner, and for a reason, that is not permitted under this Agreement or the AUP and without providing sufficient notice as required herein (“Wrongful Termination”), Customer shall be entitled to receive a dollar amount equal to: (1) in the event of the termination or deactivation of all the Services, the full amount of fees paid by Customer to Planet during the then-current term of the Agreement or (2) in the event of the termination or deactivation of a portion of the Services, the percentage of the full amount of fees paid by Customer to Planet during the then-current term of the Agreement that corresponds to the percentage of the Services terminated or deactivated relative to the total Services in effect immediately before the termination or deactivation, with the payment in either of the foregoing scenarios to be less any and all amounts owing to Planet by Customer as of the date the Wrongful Termination, as liquidated damages. The “current term” of the Agreement for this purpose shall be the period commencing on the Effective Date and ending on the date of termination or deactivation, which latter date may fall within the Initial Term or a Renewal Period. The sum is agreed upon as liquidated damages and not as a penalty. The parties hereto have computed, estimated, and agreed upon the sum as an attempt to make a reasonable forecast of probable actual loss because of the difficulty of estimating with exactness the damages which will result. These liquidated damages are Customer’s exclusive remedy against Planet for any damages whatsoever to Customer arising out of or related to a Wrongful Termination. No claim for such liquidated damages may be asserted by Customer against Planet more than [**] months following the date of termination or deactivation.

5. Indemnification. Customer agrees to indemnify and hold harmless Planet and the directors, officers, employees, and agents of Planet (each an “Indemnified Party”) against any losses, claims, damages, liabilities, penalties, actions, proceedings, judgments, or any and all costs thereof (collectively, “Losses”) to which an Indemnified Party may become subject and which Losses arise out of, or relate to the Agreement or Customer’s use of the Services, and will reimburse an Indemnified Party for all legal and other expenses, including reasonable attorneys’ fees incurred by such Indemnified Party, in connection with investigating, defending, or settling any Loss, whether or not in connection with pending or threatened litigation in which such Indemnified Party is a party.

6. Disclaimers: Limitation on Company Liability.

PLANET SHALL NOT BE LIABLE FOR (i) ANY INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES, OR FOR ANY LOSS OF PROFITS OR LOSS OF REVENUE RESULTING FROM THE USE OF THE SERVICES AND PRODUCTS BY CUSTOMER OR ANY THIRD PARTIES OR (ii) ANY LOSS OF DATA RESULTING FROM DELAYS, NONDELIVERIES, MISDELIVERIES OR SERVICE INTERRUPTIONS

PLANET PROVIDES THE SERVICES AND PRODUCTS “AS IS,” WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED AND DISCLAIMS ALL IMPLIED WARRANTIES. INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

CUSTOMER SHALL BE SOLELY RESPONSIBLE FOR THE SELECTION, USE AND SUITABILITY OF THE SERVICES AND PRODUCTS AND PLANET SHALL HAVE NO LIABILITY THEREFORE.

Except as otherwise expressly provided for in this MSA, the exclusive remedy against Planet for any damages whatsoever to

Customer arising out of or related to this Agreement shall be the refund of the fees actually paid by Customer to Planet with respect to the then-current term of this Agreement. No claim may be asserted by Customer against Planet more than [**] years following the date of the event that underlies any such claim.

7. Miscellaneous Terms.
