(1)  The number of additional shares of Class A common stock, par value $0.001
     per share, of the registrant ("Holdco Class A common stock") being
     registered is based upon the sum of (i) the product obtained by multiplying
     (x) 41,300 shares of Class A common stock, par value $0.001 per share, of
     GameStop Corp. ("GameStop Class A common stock") estimated to be
     outstanding immediately prior to the GameStop merger by (y) the exchange
     ratio of 1.0, plus (ii) the product obtained by multiplying (a) 308,374
     shares of common stock, par value $0.01 per share, of Electronics Boutique
     Holdings Corp. ("EB common stock") estimated to be outstanding immediately
     prior to the EB merger, by (b) the exchange ratio of 0.78795. The

     stock and 29,901,662 shares of Class B common stock, par value $.001 per
     share, of Holdco ("Holdco Class B common stock") on its Registration
     Statement on Form S-4 (File No. 333-125161).

(2)  Pursuant to Rules 457(f)(1) and 457(c) under the Securities Act and solely
     for the purpose of calculating the registration fee, the proposed maximum
     aggregate offering price is the sum of (i) the product obtained by
     multiplying (x) $32.42 (the average of the high and low prices of GameStop
     Class A common stock on October 5, 2005), by (y) 41,300 shares of GameStop
     Class A common stock (estimated number of shares of GameStop Class A common
     stock to be cancelled in the GameStop merger), plus (ii) the product
     obtained by multiplying (a) $63.61 (the average of the high and low prices
     of EB common stock on October 5, 2005), by (b) 308,374 shares of EB common
     stock (estimated number of shares of EB common stock to be cancelled in the
     EB merger), minus (iii) $11,764,468 (the estimated amount of cash to be
     paid by the registrant to EB's stockholders in the EB merger). Additional
     shares of Holdco Class A common stock are being registered hereby in order
     to include a good faith estimate of shares of GameStop Class A common stock
     or EB common stock or both that may be issued after the filing of this
     Registration Statement and prior to the completion of the mergers.

(3)  Calculated by multiplying the estimated aggregate offering price of
     securities to be registered by .00011770.

     filing of the Registrant's Form S-4 for the registration of 54,382,484
     shares of Holdco Class A common stock and 29,901,662 shares of Holdco Class
     B common stock. An additional registration fee of $1,100 is being paid for
     an additional 284,283 shares of Holdco Class A common stock.

(5)  Each holder of GameStop Class A common stock is entitled to one vote for
     each share of GameStop Class A common stock, and each holder of GameStop
     Class B common stock is entitled to ten votes for each share of GameStop
     Class B common stock, held on all matters properly submitted to the
