         RE:   NANOSCIENCE TECHNOLOGIES, INC.

Ladies and Gentlemen:

Reference is made to that certain Securities Purchase Agreement (the "SECURITIES
PURCHASE AGREEMENT"), dated as of December 13, 2004, by and between Nanoscience
Technologies, Inc., a Nevada corporation (the "COMPANY"), and the Buyers set
forth on Schedule I attached hereto (the "BUYER"), pursuant to which the Company
shall sell to the Buyer a minimum of One Million Dollars ($1,000,000) of the
Company's secured convertible debentures (the "Convertible Debentures"), which
shall be convertible into shares of the Company's common stock, par value $0.001
per share (the "COMMON STOCK"). The shares of Common Stock to be issued upon
conversion of the Convertible Debentures, and to be issued pursuant to the
Securities Purchase Agreement, including, without limitation, any principal,
interest or Liquidated Damages are referred to as "CONVERSION SHARES." Such
Conversion Shares shall also be deemed to include any Common Stock issued for
Liquidated Damages under the Investor Registration Rights Agreement of even date
herewith between the Company and the Buyer. This letter shall serve as our
irrevocable authorization and direction to you (provided you are the transfer
agent of the Common Stock at such time) to issue the Conversion Shares in the
event the Buyer has elected to convert all or any portion of the Convertible
Debentures, including, without limitation, principal, interest or Liquidated
Damages upon surrender to you of a properly completed and duly executed
Conversion Notice, in the form attached hereto as EXHIBIT I, delivered on behalf
of the Company by David Gonzalez, Esq.

Specifically, upon receipt by the Company or David Gonzalez, Esq. of a copy of a
Conversion Notice, David Gonzalez, Esq., on behalf of the Company, shall as soon
as practicable, but in no event later than one (1) Trading Day (as defined
below) after receipt of such Conversion Notice, sent to you, via facsimile, a
Conversion Notice, which shall constitute an irrevocable instruction to you to
process such Conversion Notice in accordance with the terms of these
instructions. Assuming you are acting as transfer agent for the Company, upon
your receipt of a copy of the executed Conversion Notice, you shall use your
best efforts to, within three (3) Trading Days following the date of receipt of
the Conversion Notice, (A) issue and surrender to a common carrier for overnight
delivery to the address as specified in the Conversion Notice, a certificate,
registered in the name of the Buyer or its designee, for the number of shares of
Common Stock to which the Buyer shall be entitled as set forth in the Conversion
Notice or (B) provided you are

                                       1
<PAGE>

participating in The Depository Trust Company ("DTC") Fast Automated Securities
Transfer Program, upon the request of the Buyer, credit such aggregate number of
shares of Common Stock to which the Buyer shall be entitled to the Buyer's or
its designee's balance account with DTC through its Deposit Withdrawal At
Custodian ("DWAC") system provided the Buyer causes its bank or broker to
initiate the DWAC transaction. ("TRADING DAY" shall mean any day on which the
Nasdaq Market is open for customary trading.)

The Company hereby confirms to you and the Buyer that certificates representing
the Conversion Shares shall not bear any legend restricting transfer of the
Conversion Shares thereby and should not be subject to any stop-transfer
restrictions and shall otherwise be freely transferable on the books and records
of the Company provided that (a) the Company counsel delivers (i) the Notice of
Effectiveness substantially in the form set forth in EXHIBIT II attached hereto,
(ii) an opinion of counsel substantially in the form set forth in EXHIBIT III
attached hereto, and (iii) the Buyer or its broker represent and warrant to you,
in writing, that it has complied with the prospectus delivery requirements, and
that if the Conversion Shares are not registered for sale under the Securities
Act of 1933, as amended, then the certificates for the Conversion Shares shall
bear the following legend:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
        SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
        MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
        ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
        THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES
        LAWS, OR AN OPINION OF COUNSEL, IN A FORM REASONABLY ACCEPTABLE TO THE
        COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE
        STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID
        ACT."

The Company hereby confirms and Interstate Transfer Company ("Interstate")
acknowledges that in the event Counsel to the Company does not issue an opinion
of counsel as required in accordance with the preceding paragraph to issue the
Conversion Shares free of legend the Company authorizes and Interstate will
accept an opinion of Counsel from David Gonzalez, Esq.

The Company hereby confirms to you and the Buyer that no instructions other than
as contemplated herein will be given to you by the Company with respect to the
Conversion Shares. The Company hereby agrees that it shall not replace
Interstate as the Company's transfer agent without the prior written consent of
the Buyer and except as set forth in the following paragraph.

Any attempt by Interstate to resign as transfer agent hereunder upon less than
fifteen (15) days written notice to the Company and the Buyer shall not be
effective until the expiration of such fifteen (15) day period.

The Company and Interstate hereby acknowledge and confirm that complying with
the terms of this Agreement shall be deemed to comply with, and shall not be
deemed to violate, any responsibilities and duties owed by Interstate to the
Company.

                                       2
<PAGE>

The Company and Interstate acknowledge that the Buyer is relying on the
representations and covenants made by the Company and Interstate hereunder and
are a material inducement to the Buyer purchasing Convertible Debentures under
the Securities Purchase Agreement. The Company and Interstate further
acknowledge that without such representations and covenants of the Company and
Interstate made hereunder, the Buyer would not enter into the Securities
Purchase Agreement and purchase Convertible Debentures pursuant thereto.

Each party hereto specifically acknowledges and agrees that in the event of a
breach or threatened breach by a party hereto of any provision hereof, the Buyer
will be irreparably damaged and that damages at law would be an inadequate
remedy if these Irrevocable Transfer Agent Instructions were not specifically
enforced. Therefore, in the event of a breach or threatened breach by a party
hereto, including, without limitation, the attempted termination of the agency
relationship created by this instrument, the Buyer shall be entitled, in
addition to any other rights or remedies it may have, to an injunction
restraining such breach, without being required to show any actual damage or to
post any bond or other security, and/or to a decree for specific performance of
the provisions of these Irrevocable Transfer Agent Instructions.

Irrevocable Transfer Agent Instructions to be duly executed and delivered as of
the date first written above.

        RE:    NANOSCIENCE TECHNOLOGIES, INC.

Ladies and Gentlemen:

We are counsel to Nanoscience Technologies, Inc., a Nevada corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Securities Purchase Agreement, dated as of December __, 2004 (the "SECURITIES
PURCHASE AGREEMENT"), entered into by and among the Company and the Buyers set
forth on Schedule I attached thereto (collectively the "BUYER") pursuant to
which the Company has agreed to sell to the Buyer a minimum of One Million
Dollars ($1,000,000) of secured convertible debentures, which shall be
convertible into shares (the "CONVERSION SHARES") of the Company's common stock,
par value $0.001 per share (the "COMMON STOCK"), in accordance with the terms of
the Securities Purchase Agreement. Pursuant to the Securities Purchase
Agreement, the Company also has entered into a Registration Rights Agreement,
dated as of December __, 2004, with the Buyer (the "INVESTOR REGISTRATION RIGHTS
AGREEMENT") pursuant to which the Company agreed, among other things, to
register the Conversion Shares under the Securities Act of 1933, as amended (the
"1933 ACT"). In connection with the Company's obligations under the Securities
Purchase Agreement and the Registration Rights Agreement, on December __, 2004,
the Company filed a Registration Statement (File No. ___-_________) (the
"REGISTRATION STATEMENT") with the Securities and Exchange Commission (the
"SEC") relating to the sale of the Conversion Shares.

In connection with the foregoing, we advise you that a member of the SEC's staff
has advised us by telephone that the SEC has entered an order declaring the
Registration Statement effective under the 1933 Act at 5:00 P.M. on __________,
2004 and we have no knowledge, after telephonic inquiry of a member of the SEC's
staff, that any stop order suspending its effectiveness has been issued or that
any proceedings for that purpose are pending before, or threatened by, the SEC
and the Conversion Shares are available for sale under the 1933 Act pursuant to
the Registration Statement.

                                  EXHIBIT II-1
<PAGE>

The Buyer has confirmed it shall comply with all securities laws and regulations
applicable to it including applicable prospectus delivery requirements upon sale
of the Conversion Shares.

                                        Very truly yours,

                                        [COMPANY COUNSEL]

Ladies and Gentlemen:

Nanoscience Technologies, Inc., a Nevada corporation (the "Company"), has filed
with the Securities and Exchange Commission a Registration Statement on Form
S-_, file no. 333-_________ (the "Registration Statement"), which became
effective under the Securities Act of 1933, as amended (the "Act"), on
______________, 2004. The Registration Statement and the related prospectus
relates to up to ________________ shares of common stock, $_______ par value, of
the Company (the "Common Stock"), which may be sold by the stockholders listed

Unless we advise you otherwise, upon your receipt of appropriate written

that (i) the number of shares of Common Stock sold by them (limited to the
number listed opposite their respective names in Exhibit A attached hereto) have
been sold pursuant to the Registration Statement and (ii) they have delivered a
copy of the Company's prospectus dated __________, 2004 to the purchasers of
such shares of Common Stock, you may issue certificates representing such shares
in the names of the transferees of the Sellers without legend regarding
restrictions on transfer under the Act and remove all stop transfer orders with
respect to the sold shares with respect to restrictions on transfer under the
Act.

This letter is for your benefit only with respect to the matters as set forth
above and may not be relied upon by any other person or for any other purpose.

                                        Very truly yours,

      SECTION 2. LIMITATIONS ON TRANSFERS OF STOCK AND INVESTMENTS IN
COMPETITORS.

            (a) During the term of this Agreement, no Stockholder shall Transfer
any Stock (i) unless such Transfer is in accordance with all applicable
securities laws or pursuant to an exemption therefrom and (ii) without first
complying with the provisions of this Section 2. Any Transfer or attempted
Transfer of any Stock in violation of any of the provisions of this Section 2
shall be void, and the Corporation shall not record such Transfer on its books
or treat any purported transferee of such Stock as the owner of such Stock for
any purpose. In furtherance and not in limitation of the foregoing, no Transfer
of Stock shall become effective unless and until the transferee executes and
delivers to the Corporation a Joinder to this Agreement pursuant to Section 16
below (a "Joinder"), agreeing to be treated in the same manner as the
transferring Stockholder (i.e., as a Preferred Stockholder, a Management
Stockholder or a Common Stockholder), with respect to the Stock so Transferred.

            (b) Except as permitted by Section 5 of the Regulatory Sideletter,
prior to August 10, 2003, no Preferred Stockholder shall Transfer any shares of
Stock, whether voluntarily, by operation of law or otherwise, without the prior
approval of the Board; provided, however, that a Preferred Stockholder may make
an Exempt Transfer of Stock without such prior approval of the Board if the
recipient of such stock shall agree in writing with the Parties to this
Agreement to be bound by and to comply with all applicable provisions of this
Agreement and to be deemed a Preferred Stockholder.

            (c) In addition to and not in limitation of Sections 2(a) and (b),
during the term of this Agreement:

                  (i) each Stockholder shall not, at any time during the term of
this Agreement, Transfer any Stock without first complying with the provisions
of Section 3; provided, that a Stockholder may make an Exempt Transfer of Stock
without complying with Section 3 if the recipient of such Stock shall agree in
writing with the Parties to this Agreement to be bound by and to comply with all
applicable provisions of this Agreement and to be deemed a Preferred
Stockholder, a Management Stockholder or a Common Stockholder, as the case may
be; and

                  (ii) each Preferred Stockholder shall not, at any time during
the term of this Agreement, Transfer any Stock without first complying with the
provisions of Section 4; provided, that a Preferred Stockholder may make an
Exempt Transfer of Stock without complying with Section 4 if the recipient of

            (d) Notwithstanding the foregoing, no Stockholder shall, at any time

recipient of such Stock is a Subsidiary of the ultimate parent entity of such
Preferred Stockholder or the ultimate parent entity of such Preferred
Stockholder.

In addition, the provisions of this Agreement shall in any case be subject in
all respects to the rights and restrictions contained in the Certificate and the
By-Laws.

            SECTION 3. RIGHT OF FIRST REFUSAL.

            Except as otherwise provided in Section 2, each Stockholder hereby
agrees that he or it shall not Transfer any Stock (other than Exempt Transfers),
except in accordance with the following procedures:

            (a) In the event such Stockholder receives and determines to accept
a bona fide arms length offer from a Person who is not an Affiliate of such
Stockholder to acquire any Stock of such Stockholder, the Selling Group shall
first deliver to the Corporation and each other Stockholder a written notice
(the "Section 3 Offer Notice"), which shall be irrevocable for a period of 15
Business Days after delivery thereof, offering (the "Section 3 Offer") all of
the Stock proposed to be Transferred by the Selling Group at the purchase price
and on the terms specified therein (such Notice of Offer shall include the
foregoing information and all other relevant terms of the proposed Transfer).
The Corporation shall have the right and option, for a period of 5 Business Days
after receipt of the Section 3 Offer Notice, to accept all, but not less than
all, of the Stock so offered at the purchase price and on the terms stated in
the Section 3 Offer Notice. Such acceptance shall be made by delivering a
written notice to the Selling Group within said 5 Business Day period.

            (b) If the Corporation fails to accept all of the Stock offered for
sale pursuant to, or shall reject in writing, the Section 3 Offer, then the
other Stockholders shall have the right and option, for a period of 10 Business
Days after the expiration of the 5 Business Day period in Section 3(a), to
accept all, but not less than all, of the Stock so offered at the purchase price
and on the terms stated in the Section 3 Offer Notice. Each Stockholder may
exercise such purchase option and purchase all or any portion of its
Proportionate Percentage of the Stock, by notifying the Corporation and the
Selling Group in writing within 10 Business Days as to the shares of Stock (up
to its full Proportionate Percentage) that it wishes to purchase. If one or more
of the Stockholders do not fully exercise their right to purchase their
respective Proportionate Percentage of the Stock pursuant to this subparagraph
(b), the Corporation shall give written notice (the "Reallocation Notice")
within 2 Business Days to all Stockholders, including the Selling Group of such
fact, and the Stockholders who have elected to exercise their rights to purchase
all of their Proportionate Percentage of the Stock pursuant to this subparagraph
(b) (the "Participating Offerees") shall have the opportunity to purchase all of
the shares of Stock with respect to which the right to purchase was not
exercised pursuant to this subparagraph (b) (the "Non-Allocated Stock"). The
Participating Offerees shall negotiate in good faith a written agreement with
each other as to the reallocation of the right to purchase the Non-Allocated
Stock and any such agreement shall be final and binding for purposes of this
Section 3; provided, however, that if the Participating Offerees cannot agree as
to the appropriate reallocation of such Non-Allocated Stock within 3 Business
Days after receipt of the Reallocation Notice, because one or more Participating
Offerees desire to purchase more than their respective pro rata share of the
Non-Allocated Stock, then the portion of the Non-Allocated Stock that each such
Participating Offeree shall be entitled to purchase shall be reduced in
proportion to its respective outstanding ownership interest in the Corporation
on the date of the Reallocation Notice until the sum of the amounts allocated to
the Participating Offerees is equal in total to the Non-Allocated

Stock; provided further, that such Participating Offeree that desires to
purchase up to its full pro rata share of the Non-Allocated Stock shall be
allocated the amount it desires to purchase. For purposes of this subparagraph
(b), each Participating Offeree's pro rata share shall be a fraction of the
Non-Allocated Stock, the numerator of which is the shares of Common Stock, on a
Common Stock Equivalent Basis, on the date of the Reallocation Notice held by
each Participating Offeree who desires to purchase any portion of the
Non-Allocated Stock and the denominator of which is the sum of the shares of
Common Stock, on a Common Stock Equivalent Basis, of all such Participating
Offerees. The Participating Offerees shall have until the end of the 10 Business
Day period specified in the first sentence of this subparagraph (b) to accept
all, but not less than all, of the Stock and to deliver to the Corporation and
the Selling Group a written agreement with respect to the purchase of the
Non-Allocated Stock pursuant to the terms of this subparagraph (b).

            (c) A notice of acceptance delivered by either the Corporation or a
Stockholder, as the case may be, pursuant to Section 3(a) or Section 3(b), shall
be an irrevocable and binding commitment to purchase the Stock referred to
therein.

            (d) Transfers of Stock under the terms of Sections 3(a) and 3(b)
shall be made at the offices of the Corporation on a mutually satisfactory
Business Day within 10 days after the expiration of the last applicable period
described in Section 3(b) above. Delivery of certificates or other instruments
evidencing such Stock duly endorsed for transfer shall be made on such date
against payment of the purchase price therefor.

            (e) If effective acceptance shall not be received pursuant to
Sections 3(a) or 3(b) with respect to all Stock offered for sale pursuant to the
Section 3 Offer Notice, then the Selling Group may Transfer all, but not less
than all, of the Stock so offered and not so accepted, but only in compliance
with Section 2(b) hereof and upon terms and conditions in all material respects,
including, without limitation, price and interest rates, which are no more
favorable, in the aggregate, to the purchaser thereof than those set forth in
the Section 3 Offer Notice, at any time within 90 days after the expiration of
the offer required by Sections 3(a) and 3(b). In the event that the Stock is not
Transferred by the Selling Group during such 90-day period, the right of the
Selling Group to Transfer such Stock shall expire and the obligations of this
Section 3 shall be reinstated.

            SECTION 4. RIGHT OF CO-SALE.

            (a) In the event that any Preferred Stockholder (hereinafter, the
"Section 4 Offeree") receives and determines to accept a bona fide arms length
offer (the "Section 4 Offer") from a third party that is not an Affiliate of
such Preferred Stockholder (the "Section 4 Offeror") to purchase all or any
portion of the shares of Stock held by such Preferred Stockholder (other than
Exempt Transfers) for a specified price payable in cash or otherwise and on
specified terms and conditions, such Section 4 Offeree shall promptly forward a
notice complying with Section 4(b) (the "Section 4 Notice") to the other
Stockholders. Subject to Section 4(c), the Section 4 Offeree shall not Transfer
any Stock to the Section 4 Offeror unless the terms of the Section 4 Offer are
extended to the other Stockholders with respect to their Proportionate
Percentage of the aggregate number of shares of Stock to which the Section 4
Offer relates, whereupon each other Stockholder shall be entitled to Transfer to
the Section 4 Offeror pursuant to the Section 4 Offer,

such other Stockholder's Proportionate Percentage of the aggregate number of
shares of Stock to which the Section 4 Offer relates.

            (b) The Section 4 Notice shall set forth (i) the number of shares of
Stock to which the Section 4 Offer relates and the name of the Section 4
Offeree, (ii) the name and address of the Section 4 Offeror, (iii) the proposed
amount and type of consideration (including, if the consideration consists in
whole or in part of non-cash consideration, such information available to the
Section 4 Offeree as may be reasonably necessary for the Stockholders to
properly analyze the economic value and investment risk of such non-cash
consideration) and the terms and conditions of payment offered by the Section 4
Offeror and (iv) that the Section 4 Offeror has been informed of the co-sale
rights provided for in this Section 4 and has agreed to purchase Stock in
accordance with the terms of this Section 4.

            (c) Anything contained herein to the contrary notwithstanding, but
subject to Section 2, the Section 4 Offeree shall, in addition to complying with
the provisions of this Section 4, comply with the provisions of Section 3 (it
being understood that the Section 3 Offer Notice contemplated by Section 3(a)
and the Section 4 Notice may be included in a single notice), and each
Stockholder, prior to Transferring any Stock to the Section 4 Offeror, shall
comply with the provisions of Section 3.

            SECTION 5. REPURCHASE RIGHT.

            (a) Repurchase of Common Stock in the Event of Termination of
Employment. In the event of a termination of a Management Stockholder's
employment by or service to the Corporation for any reason whatsoever other than
the death of such Management Stockholder (a "Repurchase Event"), such Management
Stockholder and the transferee(s) thereof following an Exempt Transfer pursuant
to the terms of this Agreement, if any (collectively, the "Management Group"),
shall be required to offer to sell to the Corporation and its Designees (as
defined below, and collectively with the Corporation, the "Corporation Group")
the Common Stock held by such Management Group pursuant to the terms of this
Section 5.

                  (i) In the event a Repurchase Event occurs, the Corporation
      shall have the right (but not the obligation) (the "Repurchase Right")
      during the 90-day period following such Repurchase Event (the "Repurchase
      Period") to purchase all or any portion of all of the Stock held by the
      Management Group (the "Repurchase Shares") in accordance with the
      provisions of this Section 5(a). During the Repurchase Period, the
      Corporation shall provide written notice of the occurrence of a Repurchase
      Event to the Board and the Management Group, which notice shall include
      the number of Repurchase Shares held by the Management Group (the
      "Repurchase Notice"). The Corporation shall, as promptly as practicable
      after a Repurchase Event, provide written notice to the Management Group
      of the determination of the Fair Market Value of the Repurchase Shares,
      with the date of determination thereof pursuant to the terms of this
      Agreement being hereinafter referred to as the "FMV Determination Date."
      The Corporation may initially elect to purchase all, or any portion, of
      the Repurchase Shares at a price equal to the Fair Market Value thereof by
      delivering a written notice of such election to the Management Group at
      any time during the Repurchase Period; provided, however, that in the
      event of a Repurchase Event caused by the termination for Cause of the
      Management

      Stockholder, the purchase price of the Repurchase Shares shall be equal to
      the lower of the Original Cost and the Fair Market Value thereof; provided
      further, however, that the Corporation's right to repurchase the Stock at
      the lower of Original Cost and the Fair Market Value shall lapse at the
      rate of 20% of the shares of Stock per year from the date the option to
      purchase such shares of Stock was granted (without respect to the date the
      option was exercised or became exercisable). Notwithstanding the
      foregoing, the Corporation's Repurchase Right shall expire on the date the
      Corporation's securities become publicly traded.

                  (ii) If the Corporation elects to purchase less than all of
      the Repurchase Shares, the Corporation shall be permitted to designate
      (the "Repurchase Designation") to one or more designees (each, a
      "Designee") the right (but not the obligation) to purchase from the
      Management Group the Repurchase Shares not being purchased by the
      Corporation (such shares being the "Designated Shares"), subject to terms
      of this paragraph and Section 16 below. The Corporation shall, as promptly
      as practicable after a Repurchase Designation, provide written notice (the
      "Designation Notice") to each Investor of the number of Designated Shares,
      the name and address of each Designee and the Fair Market Value of the
      Designated Shares. Each Investor may elect to purchase up to such
      Investor's Proportionate Percentage of the Designated Shares at a price
      equal to the purchase price for such Designated Shares determined pursuant
      to Section 5(a)(i) above by delivering a written notice of such election
      (the "Election Notice") to the Corporation within 10 Business Days of
      receipt of the Designation Notice. If the Corporation receives an Election
      Notice from an Investor, then the Corporation shall designate to such
      Investor the right to purchase that number of Designated Shares set forth
      in the Election Notice, subject to the limitations set forth in the
      preceding sentence. The number of Repurchase Shares shall be reduced by
      the aggregate number of Designated Shares set forth in the Election
      Notices, if any, received by the Corporation from the Investors. Each
      Designee shall only be permitted to purchase the number of Repurchase
      Shares (if any) equal to such Designee's pro rata portion of the aggregate
      number of Designated Shares, minus the aggregate number of shares for
      which Election Notices were received by the Corporation.

                  (iii) The number of shares of Stock to be purchased by the
      Corporation, the Designees and/or the Investors (as applicable) shall
      first be satisfied to the extent possible from the Repurchase Shares held
      by the Management Stockholder at the time of the distribution by the
      Corporation of the Repurchase Notice. If the number of Repurchase Shares
      then held by the Management Stockholder is less than the total number of
      Repurchase Shares the Corporation, the Designees and/or the Investors (as
      applicable) have elected to purchase, the Corporation, the Designees
      and/or the Investors (as applicable) shall purchase the remaining
      Repurchase Shares elected to be purchased from the other members of the
      Management Group pro rata according to the number of Repurchase Shares
      held by such other members of the Management Group at the time of
      distribution of such Repurchase Notice (determined as nearly as
      practicable to the nearest share).

            (b) Repurchase Upon Death of Management Stockholder. In the event of
the death of any Management Stockholder (including a death that occurs while the

Repurchase Event had occurred; provided, however, that (i) the Repurchase Notice
required to be delivered by the Corporation to the Board shall be delivered to
the personal representative of the Decedent promptly after being appointed as
such, (ii) the Management Stockholder, for purposes of Section 5(a) above, shall
be the Decedent's personal representative and (iii) the Management Group shall
include the Decedent and the transferee(s) thereof following an Exempt Transfer.
The Corporation may, at its option, maintain life insurance on the lives of any
Management Stockholder for the purpose of financing the acquisition of all or a
portion of Shares being repurchased from such Management Stockholder pursuant to
this Section 5(b). The proceeds of any such life insurance (the "Life Insurance
Proceeds") shall be payable to the Corporation. Each Management Stockholder
agrees to reasonably cooperate with the Corporation in connection with obtaining
any such life insurance.

            (c) Payment of Purchase Price.

                  (i) In the event that the Corporation terminates the
      Management Stockholder's employment or service without Cause, the purchase
      price payable by the Corporation, the Designees and/or the Investors (as
      applicable) pursuant to Section 5(a) or (b) above shall be payable in cash
      within 90 days after delivery of the Repurchase Notice.

                  (ii) In the event that the Management Stockholder terminates
      his employment with the Corporation or the Corporation terminates such
      employment for Cause, the purchase price payable by the Corporation, the
      Designees and/or the Investors (as applicable) pursuant to Section 5(a) or
      (b) above shall be payable as follows:

                        (A) 33.33% in cash within 90 days after delivery of the
            Repurchase Notice; and

                        (B) the remaining portion in the form of a
            non-negotiable promissory note delivered within 90 days after
            delivery of the Repurchase Notice and payable to the order of the
            applicable members of the Management Group which note shall be (1)
            dated the date of the closing of the sale transaction, bearing
            interest at the prime rate reported by The Chase Manhattan Bank,
            N.A. (or the successor thereto) in the Wall Street Journal as of
            such date, (2) payable in three equal annual installments of
            principal and interest accrued thereon payable on the anniversary of
            the date of the note, (3) prepayable at any time without premium,
            prepayments to be applied to payments of principal and then interest
            next due and (4) subordinated to any funded indebtedness of the
            Corporation.

            (d) Restrictions on Repurchases. Anything contained in this
Agreement to the contrary notwithstanding, all repurchases of shares of Common
Stock by the Corporation, the Designees and/or the Investors pursuant to this
Section 5 shall be subject to applicable restrictions contained in federal law,
the law of any other applicable jurisdiction and in the Corporation's debt and

contrary notwithstanding, if any such restrictions prohibit or otherwise delay

                  (i) Disputes. If the Management Stockholder subject to the
      Repurchase Event disputes the Fair Market Value of the Common Stock, then
      the Parties shall negotiate the Fair Market Value of the Common Stock in
      good faith. If the Parties cannot agree on the Fair Market Value of the
      Common Stock within 10 days of the initial dispute, then the Fair Market
      Value shall be determined by an independent appraiser, experienced in
      valuing businesses comparable to the business of the Corporation. Such
      appraiser shall be selected by an agreement of the Corporation and such
      Management Stockholder acting in good faith or, if the Parties are unable
      to agree, then each of the Parties shall select an appraiser meeting the
      requirements of the preceding sentence, and the two appraisers so selected
      shall jointly select a third appraiser, also meeting the requirements of
      the preceding sentence, which third appraiser (and not the other two)
      shall perform the appraisal. If either party fails to appoint an appraiser
      within 10 days after receipt of a written demand from the other party to
      do so, the appraisal will be conducted by the appraiser selected by the
      party making the demand. Within 30 days of the date the appraiser is
      selected in accordance with the terms of this definition, such appraiser
      shall make a determination of the Fair Market Value. The decision of such
      appraiser shall be final and binding. The costs and expenses of
      determining the Fair Market Value shall be paid equally by the Management
      Stockholder that is subject to the Repurchase Event, on the one hand, and
      the party or Parties purchasing such Management Stockholder's Stock, on
      the other hand.

                  (ii) No Liability. Neither the Corporation nor any officer,
      director, employee or agent of the Corporation shall have any liability
      with respect to valuation of Common Stock that are bought or sold at the
      Fair Market Value, as determined pursuant to this Agreement, even though
      the Fair Market Value, as so determined, may be more or less than actual
      fair market value, and shall be fully protected in relying in good faith
      upon the records of the Corporation and upon information, opinions,
      reports or statements presented to the Corporation by any Person as to
      matters which the Corporation or such director, officer, employee or agent
      reasonably believes are within such other Person's professional or expert
      competence and who has been selected with reasonable care by or on behalf
      of the Corporation.

            (f) Consents and Approvals. In the event that shares of Common Stock
are repurchased pursuant to this Section 5, the Management Group and the
purchasers thereof and their respective successors, assigns and representatives
shall take all steps necessary or desirable to obtain, at their sole cost and
expense, all required third-party, governmental and regulatory consents and
approvals (including, without limitation, any actions required under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended) and shall take
all other actions necessary or desirable to facilitate consummation of such
repurchase in a timely manner.

            (g) Inapplicability of Certain Sections. In the event that a
separate written agreement between the Corporation and a Management Stockholder
contains a repurchase right with respect to such Management Stockholder's Stock,
Sections 5(a), (b), (c), (d) and (f) shall not apply to such Management
Stockholder's Stock and the provisions contained in such separate written
agreement shall control and supercede such Sections with respect to such
Management Stockholder's Stock.

            SECTION 6. PREEMPTIVE RIGHTS.

            (a) Except in the case of Excluded Securities (as defined in Section
6(f) below), the Corporation shall not issue, sell or exchange, agree to issue,
sell or exchange, or reserve or set aside for issuance, sale or exchange, (i)
any Stock, (ii) any other equity security of the Corporation or any instrument
or contractual right, whether or not vested or immediately exercisable which
represents an interest in the Corporation which entitles the holder hereof to
receive capital stock or a return on such interest similar to capital stock

exchangeable for any equity security of the Corporation or has any other equity

Investor's Proportionate Percentage of such securities (the "Offered
Securities"), at a price and on such other material terms and conditions as
shall have been specified by the Corporation in writing and delivered to each
Investor (the "Offer"), which Offer by its terms shall remain open and
irrevocable for a period of 15 Business Days from the date it is delivered by
the Corporation to the Investor.

            (b) Notice of each Investor's intention to accept, in whole or in
part, an Offer shall be evidenced by a writing signed by such Investor and
delivered to the Corporation prior to the end of the 15 Business Day period of
such Offer, setting forth such portion of the Offered Securities as such
Investor elects to purchase (the "Notice of Acceptance").

            (c) In the event that Notices of Acceptance are given by the
Investors in respect of all the Offered Securities, the Investors shall purchase
from the Corporation, and the Corporation shall sell to the Investors, the

Business Days of the expiration of the 15 Business Day period set forth in
Section 6(b) above.

            (d) In the event that Notices of Acceptance are not given by the
Investors in respect of all the Offered Securities, the Corporation shall have

6(b) above to sell all or any part of such Offered Securities as to which
Notices of Acceptance have not been given by the Investor (the "Refused
Securities") to any other person or persons, but only upon terms and conditions
in all material respects, including, without limitation, price and interest
rates, which are no more favorable, in the aggregate, to such other person or
persons and no less favorable to the Corporation than those set forth in the
Offer. Upon the closing of the sale to such other Person or Persons of the

Refused Securities, which shall occur at a time within 10 Business Days of the
expiration of such 15 Business Day period that is acceptable to the Corporation
and a majority of the participating Investors and which shall include full

and the Corporation shall sell to the Investors, the Offered Securities in
respect of which Notices of Acceptance were delivered to the Corporation by the
Investors, at the terms specified in the Offer, within 15 Business Days of the
expiration of the 15 Business Day period set forth in Section 6(b) above.

            (e) Any Offered Securities offered under the circumstances described

persons in accordance with Section 6(c) or (d) may not be sold or otherwise
disposed of until they are again offered to the Investors under the procedures
specified in Sections 6(a), (b), (c) or (d).

            (f) The rights of the Investors under this Section 6 shall not apply
to issuances of the following securities (the "Excluded Securities"):

                  (i) up to 1,632,625 shares (as adjusted equitably for stock
      splits, stock dividends and the like) of Common Stock issuable upon
      exercise of stock options or pursuant to stock purchase agreements (the
      issuance of which was duly approved by the Board) granted to or entered
      into with officers, directors, employees and/or consultants of the
      Corporation or its Subsidiaries pursuant to the Stock Option Plan;

                  (ii) shares of Common Stock issued upon conversion or exercise

      split or other subdivision or combination of shares of Stock;

            SECTION 7. PUT PROVISIONS; SALE OF THE CORPORATION.

            (a) Notwithstanding any limitations on Transfers set forth in
Sections 2, 3 and 4 hereof, at any time after April 15, 2007 and prior to April
15, 2008 (the "Put Period"), GRP, provided that (i) GRP, together with its
Affiliates or other members of its Group, holds at least eighty-five (85%)
percent of the Stock of the Corporation held by it as of the Closing Date (as
adjusted for stock splits, stock dividends and the like); (ii) the Put Purchase
Price (as defined below) is at least thirty million dollars ($30,000,000); (iii)
the Corporation has not engaged, or does not have fixed plans to engage within
ninety (90) days of the time of the Section 7 Put Offer Notice (as defined
below), an investment bank of nationally recognized standing to commence a firm
commitment underwritten public offering of Common Stock of the Corporation and
(iv) a recommendation by the Board to the Stockholders to approve a sale of the

the right and option to request on one occasion (the "Sale Request") that the
Corporation and/or the other Stockholders purchase all, but not less than all,
of the Stock held by GRP and its Affiliates and the other members of its Group
(the "Put Shares") as of the date of the Sale Request upon and subject to the
terms and conditions hereinafter set forth at the Put Purchase Price (as defined
below) per Put Share:

                  (i) In order to exercise a Sale Request, GRP shall deliver to
      the Corporation, who will then forward to each other Investor during the
      Put Period a written notice (the "Section 7 Put Offer Notice"), indicating
      its desire to sell (the "Section 7 Put Offer") all, but not less than all,
      of the Put Shares in accordance with the provisions of this Section 7.

                  (ii) Upon receipt of the Section 7 Put Offer Notice, the "Put
      Fair Market Value" shall be such fair market value of the Corporation on
      the date of receipt of the Section 7 Put Offer Notice as shall be agreed
      upon between the Corporation, on the one hand, and GRP, on the other hand.
      In the absence of such agreement within forty-five (45) days from the
      Corporation's receipt of a Section 7 Put Offer Notice (the "Appraiser
      Trigger Date"), the Put Fair Market Value shall be determined by an
      independent appraiser, selected by mutual agreement of the Corporation and
      GRP, acting in good faith. If the parties are unable to agree upon such
      appraiser, then each of the Corporation and GRP shall select an appraiser,
      and the two appraisers so selected shall jointly select a third appraiser,
      which third appraiser (and not the other two) shall perform the appraisal.
      If either party fails to appoint an appraiser within fourteen (14) days
      after receipt of a written demand from the other party to do so, the
      appraisal will be conducted by the appraiser selected by the party making
      the demand. Such appraiser shall make a determination of the Put Fair
      Market Value as promptly as practicable. The Corporation shall use
      commercially reasonable efforts to assist the appraiser in completing its
      determination within thirty (30) days of its engagement. Such appraiser
      shall value the Corporation by determining the amount a willing buyer
      would pay in cash to a willing seller under no compulsion to sell for all
      of the shares of Common Stock of the Corporation on a Fully Diluted Basis,
      less the reasonably estimated transaction costs that would be incurred in
      connection with such a sale (including, without limitation, estimated
      investment banking, attorneys and accounting fees, but not taxes). The
      decision of such appraiser shall be final and binding. The Corporation and
      GRP shall, as promptly as practicable after the determination of the Put
      Fair Market Value, provide written notice to the Investors of the
      determination of the Put Fair Market Value, the aggregate number of Put
      Shares, the Put Purchase Price per Put Share and the aggregate
      consideration for the Put Shares, with the date of determination thereof
      pursuant to the terms of this Agreement being hereinafter referred to as
      the "Put FMV Determination Date."

                  (a) The costs and expenses of determining the Put Fair Market
            Value shall be paid equally by GRP, on the one hand, and the party
            or parties purchasing such Put Shares, on the other hand.

                  (b) In the event that (i) the Put Purchase Price is determined
            hereunder to be less than thirty million dollars ($30,000,000) or
            (ii) the Put Purchase Price is determined hereunder to be at least
            thirty million dollars ($30,000,000) but GRP

            determines not to extend a written Sale Request within the
            applicable period described in the first sentence of subparagraph
            (iii) below, then GRP's rights under this Section 7 shall terminate
            and the Corporation and the Investors (other than GRP) shall have no
            further obligations under this Section 7. Notwithstanding anything
            in this Section 7 to the contrary, if either of the events in the
            preceding sentence occur, the costs and expenses of determining the
            Put Fair Market Value shall be paid by GRP.

                  (iii) Within ten (10) days after the Put FMV Determination
      Date, GRP may extend a written Sale Request to the Corporation (which
      shall then notify each other Investor, of such Request) which, if made,
      shall be irrevocable during the Corporation Put Period (as defined below)
      and the Stockholder Put Period (as defined below).

                  (iv) If a valid Sale Request has been made by GRP, the
      Corporation shall have the exclusive right (but not the obligation) (the
      "Put Repurchase Right") during the ninety (90) day period following the
      determination of the Put Fair Market Value (as defined below) (the
      "Corporation Put Period") to purchase all or any portion of all of the Put
      Shares for cash in accordance with the provisions of this Section 7.

                  (v) The "Put Purchase Price" shall be determined by
      multiplying the Put Fair Market Value by a fraction (the "Fraction"), the
      numerator of which is the aggregate number of Put Shares then held by GRP
      (measured on a Common Stock Equivalent Basis), and the denominator of
      which is the aggregate number of shares of Common Stock then outstanding
      (determined on a Adjusted Treasury Stock Basis). The "Put Purchase Price
      per Put Share" shall be the Put Purchase Price divided by the aggregate
      number of Put Shares then held by GRP (measured on a Common Stock
      Equivalent Basis).

                  (vi) The Corporation may elect to purchase all, or any
      portion, of the Put Shares at a price equal to the Put Purchase Price per
      Put Share by delivering a written notice of such election to GRP and the
      other Investors at any time during the Corporation Put Period; provided
      that the Corporation shall not be obligated to purchase that portion of
      the Put Shares it so elects, if the other Investors do not purchase
      pursuant to subparagraph (b) hereof all of the remaining Put Shares not
      elected to be purchased by the Corporation.

            (b) If the Corporation fails to elect to purchase during the
Corporation Put Period all of the Put Shares offered for sale pursuant to, or
shall reject in writing, the Section 7 Put Offer, then the other Investors shall
have the right (but not the obligation), for a period of thirty (30) days after
the expiration of the Corporation Put Period (the "Stockholder Put Period"), to
accept all, but not less than all, of the remaining Put Shares not purchased by
the Corporation pursuant to subparagraph (a) hereof (the "Non-Purchased Put
Shares") at the Put Purchase Price per Put Share. Each Investor (other than GRP)
may exercise such right and purchase all or any portion of its Proportionate
Percentage of the Non-Purchased Put Shares, by notifying the Corporation in
writing within the twenty (20) day period after the end of the Corporation Put
Period (the "Initial Allocation Period") as to the shares of Non-Purchased Put
Shares (up to its full Proportionate Percentage) that it wishes to purchase. If
one or more of the Investors (other

than GRP) do not fully exercise their right to purchase their respective
Proportionate Percentage of the Non-Purchased Put Shares pursuant to this
subparagraph (b), the Corporation shall give written notice (the "Put
Reallocation Notice") within five (5) days after the end of the Initial
Allocation Period to all Investors (other than GRP), and the Investors who have
elected to exercise their rights to purchase all of their Proportionate
Percentage of the Non-Purchased Put Shares pursuant to this subparagraph (b)
(the "Participating Put Offerees") shall have the opportunity to purchase all of
the shares of Stock with respect to which the right to purchase was not
exercised pursuant to this subparagraph (b) (the "Non-Allocated Put Shares"). If
the Non-Allocated Put Shares are oversubscribed for, then the portion of the
Non-Allocated Put Shares that each such Participating Offeree shall be entitled
to purchase shall be reduced in proportion to its respective outstanding
ownership interest in the Corporation on the date of the Put Reallocation Notice
until the sum of the amounts allocated to the Participating Put Offerees is
equal in total to the Non-Allocated Put Shares; provided further, that such
Participating Put Offeree that desires to purchase up to its full pro rata share
of the Non-Allocated Put Shares shall be allocated the amount it desires to
purchase. For purposes of this subparagraph (b), each Participating Put
Offeree's pro rata share shall be a fraction of the Non-Allocated Put Shares,
the numerator of which is the number of shares of Common Stock, on a Common
Stock Equivalent Basis, on the date of delivery of the Put Reallocation Notice
held by such Participating Put Offeree and the denominator of which is the sum
of the number of shares of Common Stock, on a Common Stock Equivalent Basis,
held by all Participating Put Offerees. The Participating Put Offerees shall
have until the end of the Stockholder Put Period to elect to purchase all, but
not less than all, of the Put Shares and to deliver to the Corporation and GRP a
written notice with respect to the purchase of the Non-Purchased Put Shares
(including the Non-Allocated Put Shares) pursuant to the terms of this
subparagraph (b).

            (c) A notice of acceptance delivered by either the Corporation or a
Investor (other than GRP), as the case may be, to GRP pursuant to Section 7(a)
or Section 7(b), shall be an irrevocable and binding commitment to purchase the
Put Shares referred to therein; provided that the Corporation and/or the other
Investors, collectively, agree to purchase all, but not less than all, of the
Put Shares from GRP.

            (d) If a valid Sale Request has been made by GRP and effective
acceptance shall not be received by GRP pursuant to Sections 7(a) or 7(b) with
respect to all Put Shares offered for sale pursuant to the Section 7 Put Offer
Notice, then (i) notwithstanding anything in this Section 7 to the contrary, the
costs and expenses in determining the Put Fair Market Value shall be paid by the
Corporation and (ii) the Corporation shall retain an independent investment
banker, business broker or other agent of nationally recognized standing
selected by the Board and reasonably satisfactory to GRP (the "Broker") to
attempt during a six (6) month period after the engagement of the Broker (the
"Liquidity Attempt Period") to facilitate either (i) a Qualified Public Offering
or (ii) a Sale of the Corporation as follows:

                  (i) The Corporation shall enter into an engagement letter with
      the Broker within forty-five (45) days after the end of the Stockholder
      Put Period.

                  (ii) After the Corporation enters into an engagement letter
      with the Broker, the Corporation shall use commercially reasonable efforts
      to cooperate in connection with any potential Qualified Public Offering or
      Sale of the Corporation, and

      the Stockholders agree to comply with the provisions of the Registration
      Rights Agreement with respect to a Qualified Public Offering, and with the
      provisions of Section 9 hereof, with respect to a Sale of the Corporation,
      as applicable. Notwithstanding the foregoing, the Corporation shall afford
      to the Broker and prospective purchasers appropriate access to the
      management of the Corporation, the Corporation's books and records and the
      Corporation 's facilities (it being understood that no party shall be
      required to engage in any activity that materially interferes with the
      Corporation's business or, on a repeated basis or for an unreasonable
      length of time, interferes with an employees regular duties).

                  (iii) If the Broker obtains a "Third-Party Offer" (as defined
      below) during the Liquidity Attempt Period, and the Third-Party Offer is
      not accepted by the Corporation and the Stockholders prior to the end of
      the Liquidity Attempt Period, or if such Third-Party Offer is received by
      the Corporation within sixty (60) days of the end of the Liquidity Attempt
      Period, then within sixty (60) days after receipt by the Corporation of
      such Third-Party Offer (the "Sale Period"), GRP shall have the option, but
      not the obligation, to require the Corporation (and only the Corporation)
      to purchase for cash all of the Put Shares then held by GRP at the Put
      Purchase Price per Put Share; provided, however, that the Corporation
      shall only be obligated to purchase such Put Shares to the extent (i) such
      purchase would not cause a violation of, or not result in the Corporation
      being in violation of, any Law and (ii) after taking all steps available
      to it under Section 154 of the DGCL, the Corporation has sufficient
      capital or surplus (as computed in accordance with the DGCL) to make the
      purchase required hereunder. The Corporation shall repurchase the
      remaining Put Shares, if any, as soon as practicable after the limitations
      described in the previous sentence no longer apply, until the
      Corporation's then-existing obligations under this Section 7(d)(iii) shall
      have been discharged in full. To exercise such option, GRP shall give
      notice of such exercise to the Corporation within thirty (30) days after
      expiration of the Sale Period. The purchase price for such Put Shares
      shall be determined by multiplying the "Sale Price" (as defined below) by
      the Fraction.

                  (iv) In the event that the Corporation complies with the terms
      of this Section 7(d) and (i) the Corporation elected to pursue a Qualified
      Public Offering, but such Qualified Public Offering does not occur prior
      to the end of the Liquidity Attempt Period or (ii) (x) the Corporation
      elected to pursue a Sale of the Corporation, but the Corporation does not
      receive a Third Party Offer prior to the end of the Liquidity Attempt
      Period or (y) the Corporation has used commercially reasonable efforts to
      satisfy all closing conditions required of them under the terms of the
      Third Party Offer, but such closing conditions are not actually satisfied
      by the closing date specified in the Third Party Offer, then GRP shall be
      entitled to exercise its registration rights under Section 2 of the
      Registration Rights Agreement with respect to all, but not less than all
      of its shares and the Corporation shall have no further obligation under
      this Section 7 to purchase the Put Shares from GRP.

                  (v) For purposes of this Section 7, a "Third-Party Offer"
      means a bona fide offer (i) presented by the Broker to the Board as a bona

                  (vi) For purposes of this Section 7, the "Sale Price" means
      the amount of cash or other consideration permitted under Section 7(d)(v)
      that the Person making the Third-Party Offer offers to pay for all the
      shares of Stock of the Corporation, less the reasonably estimated
      transaction costs to be incurred in connection with such a sale and any
      sale of securities received in the transaction (including, without
      limitation, estimates of customary investment banking, Broker, attorneys
      and accounting fees).

            (e) Transfers of Stock under the terms of Sections 7(a) and 7(b)
shall be made at one closing at the offices of the Corporation on a mutually
satisfactory Business Day within thirty (30) days after the expiration of the
last applicable period described in Section 7(b) above (or such longer period
which is reasonably necessary for the requisite parties to receive regulatory
approval) (the "First Potential Put Closing Date"). Each purchaser of the Put
Shares under the terms of Sections 7(a) and 7(b) agrees to pay on the First
Potential Put Closing Date the Put Purchase Price per share for each Put Share
being purchased by such purchaser. Delivery of certificates or other instruments
evidencing such Stock duly endorsed for transfer shall be made on such date
against payment of the purchase price therefor.

            (f) Transfers of Stock from GRP to the Corporation under the terms
of Section 7(d)(iii) shall be made at one closing at the offices of the
Corporation on a mutually satisfactory Business Day as soon as commercially
reasonable, but in no event later than six (6) months after the expiration of
the Sale Period (the "Second Potential Put Closing Date"). If the conditions are
met for the Corporation to purchase the Put Shares under the terms of Sections
7(d)(iii), the Corporation agrees to pay on the Second Potential Put Closing
Date the Put Purchase Price per share for each Put Share being purchased by the
Corporation, together with simple interest thereon from the date after the end
of the Sales Period to the Second Potential Put Closing Date at the rate of
eight (8%) percent per annum. Delivery of certificates or other instruments
evidencing such Stock duly endorsed for transfer shall be made on such date
against payment of the purchase price therefor.

            (g) In addition to and not in limitation of Section 15 hereof, this
Section 7 shall terminate and be of no force and effect upon a Liquidity Event
or upon any material breach by GRP of this Agreement, the Series C-1 Securities
Purchase Agreement or the Registration Rights Agreement.

            SECTION 8. COVENANTS OF THE CORPORATION.

            (a) Financial Information. The Corporation will deliver the
following reports to each Preferred Stockholder so long as such Preferred
Stockholder together with its Affiliates holds shares of Preferred Stock
representing at least 250,000 shares of capital stock of the Corporation (as
adjusted equitably for stock dividends, stock splits, combinations, etc.):

                  (i) As soon as practicable after the end of each fiscal year,
      and in any event within ninety (90) days thereafter, the consolidated
      audited balance sheet of the Corporation and its Subsidiaries, if any, as
      of the end of such fiscal year, and a consolidated statement of income and
      consolidated statement of cash flow of the Corporation and its
      Subsidiaries, if any, for such fiscal year, prepared in accordance with
      GAAP, consistently applied and setting forth in each case in comparative
      form the figures for the previous fiscal year, all in reasonable detail
      and audited by independent public accountants of national standing
      selected by the Corporation, together with a certificate of the
      Corporation executed by the chief executive officer or principal financial
      or accounting officer of the Corporation certifying that all covenants to
      be complied with by the Corporation under this Section 8 have been
      complied with (or setting forth in reasonable detail any covenants that
      have not been so complied with) and the reasons for such noncompliance.

                  (ii) As soon as practicable after the end of each quarter and
      in any event within forty-five (45) days thereafter, an unaudited

      the corresponding period of the prior year).

            (b) Additional Information. The Corporation will deliver the
following additional items to each Preferred Stockholder so long as such
Preferred Stockholder together with its Affiliates holds shares of Preferred
Stock representing at least (x) five (5%) percent of the total Common Stock of
the Company on a Fully Diluted Basis; provided, however, that if such Preferred
Stockholder together with its Affiliates initially holds shares of Preferred
Stock representing at least five (5%) percent threshold and subsequently goes
below such five (5%) percent threshold solely as a result of the Corporation
issuing additional securities of the Corporation after the date hereof, then
such threshold percentage shall be reduced to three (3%) percent for such
Preferred Stockholder together with its Affiliates; provided further, however,
that such Preferred Stockholder who subsequently goes below such five (5%)
percent threshold has not sold or transferred any shares of Preferred Stock to
any Persons who is not an Affiliate of such Preferred Stockholder as of the date
of determination of rights to additional information hereunder, or (y) 1,250,000
shares of Stock of the Corporation (as adjusted equitably for stock dividends,
stock splits, combinations, etc.) each, a "Qualified Investor"):

      any event within twenty (20) days thereafter, an unaudited consolidated
      balance sheet and statements of income and cash flow of the Corporation
      and its Subsidiaries, if any, prepared on a trended basis for such month
      and for the year to date (in each case compared to the budget for that
      period and to the corresponding periods of prior years).

requested; provided, however, that each such Qualified Investor shall agree to
hold all such materials and information derived therefrom as confidential and
shall not reveal or disclose such materials or information derived therefrom to
any other Person (other than a Subsidiary of the ultimate parent entity of such
Qualified Investor) unless compelled by applicable Law.

            SECTION 9. APPROVED SALE OF THE CORPORATION.

            (a) If a majority of the Board and the Requisite Designated
Preferred Stockholders approve a Sale of the Corporation (an "Approved Sale"),
each Stockholder shall consent to and raise no objections against the Approved
Sale. If the Approved Sale is structured as a (i) merger or consolidation of the
Corporation or a sale of all or substantially all of the assets of the
Corporation (determined on a consolidated basis), each Stockholder shall waive
any dissenters rights, appraisal rights or similar rights in connection with
such merger, consolidation or asset sale, or (ii) sale of Stock, each
Stockholder shall agree to sell their Stock on the terms and conditions
(including the same price per share) approved by the Board and the Requisite
Designated Preferred Stockholders, subject to the conditions set forth in
Section 9(b). Each Stockholder shall take all necessary and desirable actions in
connection with the consummation of the Approved Sale including, but not limited
to, the execution of such agreements and such instruments and other actions
reasonably necessary to effectuate the allocation and distribution of the
aggregate consideration upon the Approved Sale as set forth in Section 9(b).

            (b) The obligations of each Stockholder with respect to an Approved
Sale are subject to the satisfaction of the following conditions: (i) upon the
consummation of the Approved Sale, all of the Stockholders shall receive the

that each such Stockholder would have received if such aggregate consideration
had been distributed by the Corporation in complete liquidation pursuant to the

rights and preferences set forth in the Certificate, (ii) if any Stockholders
are given an option as to the form and amount of consideration to be received,
each Stockholder will be given the same option, (iii) subject to the terms and
conditions of the Stock Option Plan, all holders of rights to acquire Stock (to
the extent such rights are vested) shall be given an opportunity to either (A)
exercise such rights prior to the consummation of the Approved Sale and
participate in such sale as holders of Stock or (B) upon the consummation of the
Approved Sale, receive in exchange for such rights consideration equal to the
amount determined by multiplying (1) the number of shares of Stock represented
by such rights by (2) the consideration a holder of such share of Stock would
receive in connection with the Approved Sale less the exercise price per share
of Stock, (iv) no Stockholder shall be required pursuant to the terms of such
sale to accept any consideration that would cause such Stockholder to have a
Regulatory Problem (as such term is defined in the Regulatory Sideletter) and
(v) no Stockholder will be entitled to receive any economic benefits (other than
in connection with such Stockholder's employment with the Corporation) which are
not made available on a pro rata basis to all the other Stockholders (except
that this provision shall not apply to advisory, accounting, legal or other
services rendered for the Corporation by a Stockholder who has been engaged by
the Board for such purpose).

            (c) The Preferred Stockholders shall only be required to give
representations, warranties and indemnities with respect to their respective
organization, authorization, enforceability, ownership of stock, and
noncontravention of contracts customary to transactions of such type. In no
event shall the Preferred Stockholders be required to make any representations,
warranties or indemnities with respect to the operations of the Corporation or
the Corporation's business in connection with any Approved Sale.

            SECTION 10. ELECTION OF DIRECTORS; VOTING.

each member of the Board shall at all times serve as a director on the board of

decrease in the number of directors constituting such board. Notwithstanding any
provision in the Certificate and the By-Laws, the number of directors
constituting the Board shall not be changed without the consent of the Requisite
Designated Preferred Stockholders. At each annual meeting of the holders of any
class of Stock, and at each special meeting of the holders of any class of Stock

at which holders of any class of Stock shall have the right to, or shall, vote

            SECTION 11. REGULATORY MATTERS.

            (a) Cooperation of Other Stockholders.

                  (i) Each Stockholder agrees to cooperate with the Corporation
      in all commercially reasonable respects in complying with the terms and
      provisions of the Regulatory Sideletter (each of J.P. Morgan and Wells
      Fargo, a "Regulated Investor"), regarding regulatory matters in order to
      remedy a Regulatory Problem (as defined in the Regulatory Sideletter),
      including without limitation, voting to approve amending the Certificate,
      the By-Laws or this Agreement in a manner reasonably acceptable to the
      Stockholders, the Corporation, each Regulated Investor or any Affiliate of
      a Regulated Investor entitled to make such request under the Regulatory
      Sideletter.

                  (ii) Each Stockholder and the Corporation agree to cooperate
      in all commercially reasonable respects with each other Stockholder and
      the Corporation should any Stockholder or any Affiliate of such
      Stockholder (an "Other Regulated Investor") after the date of this
      Agreement become directly subject to any regulatory body or fall under the
      direct regulatory supervision of any regulatory body solely because of
      such Other Regulated Investor's equity interest in the Corporation, as a
      result of which the business activities of the such Other Regulated
      Investor or its Affiliate are materially and adversely limited or the cost
      of such activities are materially increased (an "Other Regulatory
      Problem"), to eliminate such Other Regulatory Problem, including without
      limitation, voting to approve amending the Certificate, the By-Laws or
      this Agreement in a manner reasonably acceptable to the Stockholders, the
      Corporation and the Other Regulated Investor.

                  (iii) Anything contained in this Section 11(a) to the contrary
      notwithstanding, the Corporation and each Stockholder hereby agree that no
      Stockholder

      or the Corporation shall be required under this Section 11(a) to take any
      action that would adversely affect in any material respect (i) such
      party's rights under this Agreement or any Stockholder's rights as a
      stockholder of the Corporation; (ii) the fair market value of such
      Stockholder's investment in the Corporation (but not including any general
      affect on the fair market value of the Corporation); or (iii) the
      operation of such Stockholder's, any of its Affiliates' or the
      Corporation's business.

            (b) Each Stockholder agrees to cooperate in all commercially
reasonable respects with each other Stockholder and the Corporation should any
such Stockholder (the "Causing Stockholder") after the date of this Agreement
and as a result of its ownership of securities of the Corporation or other
relationships with the Corporation cause the Corporation to become directly
subject to any regulatory body or fall under the direct regulatory supervision
of any regulatory body, as a result of which the business activities of the
Corporation are materially and adversely limited or the Corporation incurs any
additional costs (a "DealerTrack Regulatory Problem"), to eliminate such
DealerTrack Regulatory Problem, including without limitation, voting to approve
amending the Certificate, the By-Laws or this Agreement in a manner reasonably
acceptable to the Stockholders, the Corporation, each Regulated Investor, any
Affiliate of a Regulated Investor entitled to make such request pursuant to the
Regulatory Sideletter in order to remedy a Regulatory Problem (as defined in the
Regulatory Sideletter) and any Other Regulated Investor. For the purpose of this
Section 11(b) only, commercially reasonable shall include the Causing
Stockholder's (but not any other Stockholder's) disposition of its equity
interest in the Corporation at a loss in the event such DealerTrack Regulatory
Problem has not otherwise been eliminated and cannot be eliminated by other
commercially reasonable efforts of the Causing Stockholder (such as the transfer
of the Causing Stockholder's equity interest in the Corporation to an Affiliate)
or the commercially reasonable efforts of the other Stockholders. Anything
contained in this Section 11(b) to the contrary notwithstanding, the Corporation
and each Stockholder hereby agree that any Stockholder who is not the cause of
the DealerTrack Regulatory Problem, shall not be required under this Section
11(b) to take any action that would adversely affect in any material respect (i)
such Stockholder's rights under this Agreement or as a stockholder of the
Corporation; (ii) the fair market value of such Stockholder's investment (but
not including any general affect on the fair market value of the Corporation) in
the Corporation; or (iii) the operation of such Stockholder's or any of its
Affiliates' business.

            (c) Covenant Not to Amend. The Corporation and each Stockholder
agree not to amend or waive the voting or other provisions of the Certificate,
the By-Laws or this Agreement if such amendment or waiver would cause either (i)
either Regulated Investor or any of their respective Affiliates to have a
Regulatory Problem (as defined in the Regulatory Sideletter) or (ii) any other
Stockholder or any of its Affiliates to have an Other Regulatory Problem. Each
Regulated Investor and each other Stockholder agrees to notify the Corporation
as to whether or not it or any of its Affiliates would have a Regulatory Problem
or Other Regulatory Problem promptly after such Regulated Investor and each
other Stockholder has notice of such amendment or waiver. Anything contained in
this Section 11(c) to the contrary notwithstanding, the Corporation and each
Stockholder hereby agree that no Stockholder shall be required under this
Section 11(c) to take any action that would adversely affect in any material
respect (i) such Stockholder's rights under this Agreement or as a stockholder

            THE SALE, TRANSFER, ASSIGNMENT, PLEDGE, OR ENCUMBRANCE OF THE
            SECURITIES REPRESENTED BY THIS CERTIFICATE AND THE RIGHTS OF THE
            HOLDER OF SUCH SECURITIES IN RESPECT OF THE ELECTION OF DIRECTORS
            ARE SUBJECT TO THE TERMS AND CONDITIONS OF A STOCKHOLDERS' AGREEMENT
            DATED AS OF MARCH 19, 2003 AMONG DEALERTRACK HOLDINGS, INC., ITS
            SUBSIDIARIES AND THE HOLDERS OF OUTSTANDING CAPITAL STOCK OF SUCH
            CORPORATION, AS AMENDED FROM TIME TO TIME. COPIES OF SUCH AGREEMENT
            MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF
            RECORD OF THIS CERTIFICATE TO THE SECRETARY OF DEALERTRACK HOLDINGS,

            DEALERTRACK HOLDINGS, INC. WILL FURNISH WITHOUT CHARGE TO EACH
            STOCKHOLDER WHO SO REQUESTS THE POWERS, DESIGNATIONS, PREFERENCES
            AND RELATIVE, PARTICIPATING, OPTIONAL, OR OTHER SPECIAL RIGHTS OF

            LIMITATIONS OR RESTRICTIONS OF SUCH PREFERENCES AND/OR RIGHTS."

            (b) Opinion of Counsel. Unless the requirements of this Section
13(b) are waived by the Corporation with respect to a Transfer, no Stockholder
may consummate a Transfer of any Stock to any Person that is not a party to this
Agreement (except pursuant to an effective registration statement under the
Securities Act) without first delivering to the Corporation an opinion of
counsel (reasonably acceptable in form and substance to the Corporation) that
neither the registration nor qualification under the Securities Act and
applicable state securities laws is required in connection with such Transfer;
provided, however, that the requirements of this Section 13(b) shall not apply
to any Exempt Transfer by a Preferred Stockholder.

            SECTION 14. ADDITIONAL SHARES OF STOCK.

            In the event additional shares of Stock are issued by the
Corporation after the date hereof, either directly or upon the exercise or
exchange of securities of the Corporation exercisable for or exchangeable into
shares of Stock, the Corporation shall cause such additional shares of Stock, as
a condition to such issuance, to become subject to the terms and provisions of
this Agreement.

            SECTION 15. DURATION OF AGREEMENT.

            The rights and obligations of each Stockholder under this Agreement
shall terminate as to such Stockholder upon the Transfer of all Stock owned by
such Stockholder. This Agreement shall terminate as to all Parties hereto in any
event immediately prior to the consummation of a Qualified Public Offering.

            SECTION 16. JOINDERS; AMENDMENT OF ANNEX I.

            (a) Any transferee of Stock of the Corporation from a Preferred
Stockholder (other than the Corporation, a Common Stockholder or a transferee in
a Qualified Public Offering) shall, as a condition to such Transfer, become a
Preferred Stockholder for purposes of this Agreement, and if such transferee is
not already bound hereby as a Preferred Stockholder, he, she or it shall execute
and deliver to the Corporation a Preferred Stockholder Joinder in substantially
the form of Exhibit B. Any transferee of Stock from a Common Stockholder who is
not a Management Stockholder (other than the Corporation, a Preferred
Stockholder, a transferee in a Qualified Public Offering or an employee,
manager, officer or director of or consultant to the Corporation) shall, as a
condition to such Transfer, become a Common Stockholder for purposes of this
Agreement, and if such transferee is not already bound hereby as a Common
Stockholder, he, she or it shall execute and deliver to the Corporation a Common
Stockholder Joinder in substantially the form of Exhibit C. Any transferee of
Stock from a Management Stockholder (other than the Corporation, a Preferred
Stockholder or a transferee in a Qualified Public Offering) shall, as a
condition to such Transfer, become a Management Stockholder for purposes of this
Agreement, and if such transferee is not already bound hereby as a Management
Stockholder, he, she or it shall execute and deliver to the Corporation a
Management Stockholder Joinder in substantially the form of Exhibit D.

            (b) In the event additional shares of Stock are issued by the
Corporation after the date hereof to any Person that is an employee, manager,
officer or director of or consultant to the Corporation (including pursuant to
the exercise of an option to acquire Stock), such Person, as a condition to
receiving such shares of Stock, shall execute and deliver to the Corporation a
Joinder in substantially the form of Exhibit D hereto, and shall be deemed a
Management Stockholder hereunder and shall agree that such shares of Stock will
be subject to the terms and provisions of this Agreement, provided that if such
Person was a Management Stockholder prior thereto, such Person shall be deemed
to continue such status.

            (c) In the event shares of Stock are issued by the Corporation after
the date hereof to a third party investor which is not an Affiliate, employee,
manager, officer or director of or consultant to the Corporation, such Person,
as a condition to receiving such shares of Stock, shall agree to execute and
deliver to the Corporation a Joinder in substantially the form of Exhibit C
hereto, and shall be deemed a Stockholder hereunder and agree that such
additional shares will be subject to the terms and provisions of this Agreement
provided that if such Person was a Common Stockholder prior thereto, such Person
shall be deemed to have continued such status and if such Person was a Preferred
Stockholder prior thereto, such Person shall be deemed to have continued such
status.

            (d) Notwithstanding anything contained in this Agreement to the
contrary, Annex I shall automatically be amended to reflect the Stock held by
each Preferred Stockholder, Common Stockholder and Management Stockholder upon
the occurrence of (i) the execution and delivery of a Joinder or (ii) the
acquisition of Stock. Within 30 days of any amendment to Annex I, the
Corporation shall deliver the revised Annex I to each Stockholder at the address
held on the books and records of the Corporation.

            SECTION 17. SEVERABILITY; GOVERNING LAW.

            It is the desire and intent of the Parties that the provisions of
this Agreement be enforced to the fullest extent permissible under the Laws and
public policies applied in each jurisdiction in which enforcement is sought.
Accordingly, if any particular provision of this Agreement shall be adjudicated
by a court of competent jurisdiction to be invalid, prohibited or unenforceable
for any reason, such provision, as to such jurisdiction, shall be ineffective,
without invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction. Notwithstanding the
foregoing, if such provision could be more narrowly drawn so as not to be
invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provision in any other jurisdiction. This Agreement shall be governed by and
construed and enforced in accordance with the Laws of the State of New York
(without regard to principles of conflict of Laws), except to the extent that
this Agreement relates to the internal Laws of the Corporation, which shall be
governed by and construed and enforced in accordance with the Laws of the State
of Delaware.

            SECTION 18. SUCCESSORS AND ASSIGNS.

legal representatives, heirs and estate.

            All such notices, requests, consents and other communications shall
be deemed to have been delivered (a) in the case of personal delivery or
delivery by telecopy, on the date of such delivery, (b) in the case of dispatch
by nationally-recognized overnight courier, on the next business day following
such dispatch and (c) in the case of mailing, on the third business day after
the posting thereof.

            SECTION 20. MODIFICATION; WAIVER.

            Neither this Agreement nor any provisions hereof can be modified,
changed, discharged, waived or terminated, except by an instrument in writing
signed by the Corporation and the Requisite Designated Preferred Stockholders
(as defined in the Certificate); provided, that any such modification, change,
discharge, waiver or termination shall also require the written consent of any
particular party hereto to the extent, and only to the extent, that any such
modification, change, discharge, waiver or termination materially adversely
affects the rights, privileges, duties or obligations of such party hereunder as
compared to those of the other Parties hereto. No waiver by any party of any
default, misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence. The failure of any party to enforce any of the provisions of this
Agreement shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with it terms.

            SECTION 21. VOTING.

            To the extent that the Corporation wishes to take any action
requiring approval under Section 4.1(c)(ii) of the Certificate, if such action
is approved as required by such Section 4.1(c)(ii) then each Stockholder agrees
to vote all shares of capital stock of the Corporation held by such Stockholder
in favor of such action, whether by written consent or at any meeting.
Notwithstanding the foregoing, nothing contained in this Section 21 shall be
construed as requiring a Stockholder to vote its shares in favor of any action
if such Stockholder owns capital stock of any class or series that would be
entitled to vote as a separate class or series with respect to such action under
Section 242(b)(2) of the DGCL.

            SECTION 22. REMEDIES.

            (a) Each Stockholder shall have all rights and remedies reserved for
such Stockholder pursuant to this Agreement and all rights and remedies which
such holder has been granted at any time under any other agreement or contract
and all of the rights which such holder has under any Law or equity. Without
limiting the generality of the foregoing, a Person having any rights under any
provision of this Agreement will be entitled to enforce such rights
specifically, to recover damages by reason of any breach of any provision of
this Agreement and to exercise all other rights granted by Law or equity.

            (b) The Parties acknowledge and agree that, solely with respect to
Section 9 and Section 10 hereof, it will be impossible to measure in money the
damages that would be suffered by any party hereto if any Person which is also a
party hereto fails to comply with any of the obligations imposed on it in this
Agreement or in the Certificate or By-Laws, and that in the event of any such
failure, the aggrieved party will be irreparably damaged and will not have an
adequate remedy at law. Any such aggrieved party shall, therefore, be entitled
to equitable relief, including specific performance, to enforce such
obligations, and if any action should be brought in equity to enforce any of the
provisions of this Agreement, none of the Parties hereto shall raise the defense
that there is an adequate remedy at law.

            SECTION 23. NO DISCLOSURE OBLIGATIONS.

            (a) The Corporation and each Stockholder acknowledges that each
Investor will likely have, from time to time, information that may be of
interest to the Corporation ("Information") regarding a wide variety of matters
including, without limitation, (1) the Investor's technologies, products, plans
and services, and plans and strategies relating thereto, (2) current and future
investments the Investor has made, may make, may consider or may become aware of
with respect to other Persons and other technologies, products, plans and
services, and plans and strategies relating thereto, including, without
limitation, those that may be competitive with the Corporation's, and (3)
developments with respect to the technologies, products plans and services, and
plans and strategies relating thereto, of other Persons, including, without
limitation, Persons that may be competitive with the Corporation. The
Corporation and each Stockholder recognizes that a portion of such Information
may be of interest to the Corporation and that such Information may or may not
be known by the applicable Investor Director. The Corporation and each
Stockholder agree that the Investors and each Investor Director shall have no
duty to disclose any Information to the Corporation or permit the Corporation to
participate in any projects or investments based on any Information, or to
otherwise take advantage of any opportunity that may be of interest to the
Corporation if it were aware of such Information, and hereby waives, to the
extent permitted by law, any claim based on the corporate opportunity doctrine
or otherwise that could limit Investor's ability to pursue opportunities based
on such Information or that would require the Investor or the Investor Director
to disclose any such Information to the Corporation or offer any opportunity
relating thereto to the Corporation.

Agreement.

            SECTION 25. NOUNS AND PRONOUNS.

form of names and pronouns shall include the plural and vice versa.

            SECTION 26. ENTIRE AGREEMENT.

embodies the complete agreement and understanding among the Parties hereto with
respect to the subject matter hereof and supersedes and preempts any prior
understandings or representations by or among the Parties, written or oral,
which may have related to the subject matter hereof in any way.

            SECTION 27. COUNTERPARTS.

            This Agreement may be executed in any number of counterparts, and
each such counterpart hereof shall be deemed to be an original instrument, but
all such counterparts together shall constitute but one agreement.

            SECTION 28. AMENDED AND RESTATED AGREEMENT.

            The Parties hereto agree that upon the proper and duly authorized
execution and delivery of this Agreement, the Prior Stockholders' Agreement
shall be superceded by this Agreement and cancelled in its entirety.
