                      SENIOR EXECUTIVE INCENTIVE BONUS PLAN

1.    Purpose

      This Senior Executive Incentive Bonus Plan (the "Incentive Plan") is
intended to provide an incentive for superior work and to motivate eligible
executives of DealerTrack Holdings, Inc. (the "Company") and its subsidiaries
toward even higher achievement and business results, to tie their goals and
interests to those of the Company and its stockholders and to enable the Company
to attract and retain highly qualified executives. The Incentive Plan is for the
benefit of Covered Executives (as defined below).

2.    Covered Executives

      From time to time, the Compensation Committee of the Board of Directors of
the Company (the "Compensation Committee") may select certain key executives
(the "Covered Executives") to be eligible to receive bonuses hereunder.

3.    Administration

      The Compensation Committee shall have the sole discretion and authority to
administer and interpret the Incentive Plan.

4.    Bonus Determinations

      (a) A Covered Executive may receive a bonus payment under the Incentive
Plan based upon the attainment of performance objectives which are established
by the Compensation Committee and relate to financial, operational or other
metrics with respect to the Company or any of its subsidiaries (the "Performance
Goals"), including but not limited to: (i) net income (loss) (either before or
after interest, taxes, depreciation and/or amortization), (ii) sales or revenue,
(iii) acquisitions or strategic transactions, (iv) operating income (loss), (v)
cash flow (including, without limitation, operating cash flow and free cash
flow), (vi) return on capital, (vii) return on assets (including, without
limitation, return on net assets), (viii) return on stockholders' equity, (ix)
economic value added, (x) stockholder returns, (xi) return on sales, (xii) gross
or net profit margin, (xiii) productivity, (xiv) expenses, (xv) margins, (xvi)
operating efficiency, (xvii) customer satisfaction, (xviii) working capital,
(xix) earnings (loss) per share, (xx) price per share of equity securities,
(xxi) market share, and (xxii) number of customers, any of which may be measured
either in absolute terms or as compared to any incremental increase or decrease,
or as compared to results of a peer group.

      (b) Except as otherwise set forth in this Section 4(b): (i) any bonuses
paid to Covered Executives under the Incentive Plan shall be based upon
objectively determinable bonus formulas that tie such bonuses to one or more
performance objectives relating to the Performance Goals, (ii) bonus formulas
for Covered Executives shall be adopted in each performance period by the
Compensation Committee and (iii) no bonuses shall be paid to Covered Executives
unless and until the Compensation Committee makes a certification with respect
to the attainment of the performance objectives. Notwithstanding the foregoing,
the Company may pay bonuses (including, without limitation, discretionary
bonuses) to Covered Executives under the Incentive

Plan based upon such other terms and conditions as the Compensation Committee
may in its discretion determine.

      (c) The payment of a bonus to a Covered Executive with respect to a
performance period shall be conditioned upon the Covered Executive's employment
by the Company on the last day of the performance period; provided, however,
that the Compensation Committee may make exceptions to this requirement, in its
sole discretion, including, without limitation, in the case of a Covered
Executive's termination of employment, retirement, death or disability.

5. Amendment and Termination

      The Company reserves the right to amend or terminate the Incentive Plan at
any time in its sole discretion. Any amendments to the Incentive Plan shall
require stockholder approval only to the extent required by any applicable law,
rule or regulation.

6. Stockholder Approval

      No bonuses shall be paid under the Incentive Plan unless and until the
Company's stockholders shall have approved the Incentive Plan. The Incentive
Plan will be submitted for the approval of the Company's stockholders after the
initial adoption of the Plan by the Board of Directors of the Company.

7. Term of Plan

      The Incentive Plan shall become effective as of May 26, 2005. The
Incentive Plan shall expire on the earliest to occur of: (a) the first material
modification of the Incentive Plan (as defined in Treasury Regulation Section
1.162-27(h)(1)(iii)); (b) the first meeting of the Company's stockholders at
which members of the Board of Directors of the Company are to be elected that

which occurred the first registration of an equity security of the Company under

date required by Section 162(m) of the Code and the rules and regulations
promulgated thereunder (including without limitation Treasury Regulation Section
