Exhibit 10.10

GUARANTEE

In order to induce ROSENTHAL & ROSENTHAL, INC. (herein called “Rosenthal”) to make loans, advances or other commitments or grant other financial accommodations to or for the account of (or in reliance on the credit of) EDGAR Online, Inc. (herein called “Obligor”) and for other good and valuable considerations received, the undersigned irrevocably and unconditionally guarantees to Rosenthal payment when due, whether by acceleration or otherwise, of any and all Obligations of the Obligor to Rosenthal. The term “Obligations” shall mean all obligations, liabilities and indebtedness of the Obligor to Rosenthal or an affiliate of Rosenthal, however evidenced, now or hereafter arising under the Financing Agreement, dated as of the date hereof, between Rosenthal and Obligor, as the same may have been or may in the future be supplemented and/or amended (the “Financing Agreement”) and/or under any other or supplemental financing provided to the Obligor by Rosenthal or an affiliate of Rosenthal, or independent hereof or thereof, whether now existing or incurred from time to time hereafter and whether before or after termination hereof, absolute or contingent, joint or several, matured or unmatured, direct or indirect, primary or secondary, liquidated or unliquidated, and whether arising directly or acquired from others (whether acquired outright, by assignment unconditionally or as collateral security from another and including, without limitation, participations or interest of Rosenthal in obligations of Obligor to others), and including (without limitation) all of Rosenthal’s charges, commissions, fees, interest, expenses, costs and reasonable attorneys’ fees chargeable to Obligor in connection therewith. In addition, the undersigned agrees to indemnify Rosenthal against any loss, damage or liability because of any wrongful acts or fraud of the Obligor.

The undersigned waives notice of acceptance of this Guarantee and notice of any liability to which it may apply, and waives presentment, demand for payment, protest, notice of dishonor or nonpayment of any Obligations, or suit or taking other action by Rosenthal against, and any other notice to, any party liable thereon (including the undersigned) and waives any defense, offset or counterclaim to any liability hereunder. Rosenthal may at any time and from time to time (whether or not after revocation or termination of this Guarantee) without the consent of, or notice to, the undersigned, without incurring responsibility to the undersigned, without impairing or releasing the obligations of the undersigned hereunder, upon or without any terms or conditions and in whole or in part: (1) change the manner, place or terms of payment, and/or change or extend the time of payment of, renew or alter, any Obligation, any security therefor, or any liability incurred directly or indirectly in respect thereof, and the Guarantee herein made shall apply to the Obligations as so changed, extended, renewed or altered; (2) sell, exchange, release, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the liabilities hereby guaranteed or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or offset thereagainst; (3) exercise or refrain from exercising any rights against the Obligor or others (including the undersigned) or otherwise act or refrain from acting; (4) settle or compromise any Obligation, any security therefor or any liability

(including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Obligor to creditors of the Obligor other than Rosenthal and the undersigned: and (5) apply any sums by whomsoever paid or howsoever realized to any Obligation to Rosenthal regardless of what liability or liabilities of the Obligor remain unpaid.

No invalidity, irregularity or unenforceability of all or any part of the liabilities hereby guaranteed or of any security therefor shall affect, impair or be a defense to this Guarantee. The liability of the undersigned hereunder is primary and unconditional and shall not be subject to any offset, defense or counterclaim of the Obligor. This Guarantee is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. The books and records of Rosenthal shall be admissible as prima facie evidence of the Obligations. As to each of the undersigned, this Guarantee shall continue until written notice of revocation signed by such undersigned, or until written notice of the death of such undersigned shall in each case have been actually received by Rosenthal, notwithstanding a revocation by, or the death of, or complete or partial release for any cause of any one or more of the remainder of the undersigned or of the Obligor, or of any one liable in any manner for the liabilities hereby guaranteed, or for the liabilities (including those herein) incurred directly or indirectly in respect thereof or hereof, and notwithstanding the
