         Each of you hereby grants to the Underwriters a 45-day option to
purchase half of the shares of Common Stock issuable to you upon conversion of
the shares of Series A Preferred Stock of the Company owned by you solely to
cover over-allotments, if any. You represent that such shares aggregate 57,500
shares of Common Stock. Upon receipt of written notice from the Underwriters you
may elect either to: (1) not sell your shares of Common Stock subject to this
option, in which event you will immediately notify the Company by telephone and
fax transmission and the Company shall honor the Underwriter's overallotment
option exercise and you will have no further right to participate in the
proposed public offering, or (2) to sell your shares of Common Stock subject to
this option in which case you will immediately convert such number of shares of
Series A Preferred Stock as shall be necessary to deliver promptly, but in any
event within two days, whatever number of shares of Common Stock, up to 57,500,
the Underwriters shall request of you. You understand that the Underwriters must
exercise in full the over-allotment options granted to them by the Company
before they may exercise any of the over-allotment option granted to them by
you. You agree to enter into whatever arrangement is reasonably necessary to
effect the purpose of this option including, without limitation, granting Jack
Augsback a power of attorney to act on your behalf in accepting or rejecting the
option, converting your shares of Series A Preferred Stock to make available
shares of Common Stock for delivery to the Underwriters, and delivering your
shares of Common Stock to the underwriters. In addition, at the request of the
Underwriter, you will enter into an agreement with Mr. Augsback pursuant to
which you will the certificates representing your shares of Series A Preferred
Stock and he will act as custodian for such shares pending termination of the
option granted herein.

         Each of you hereby consents to the disclosure of your names and
shareholdings in the prospectus for the offering, in conformity with the
requirements of the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder. Each of you represents that the only shares
of capital stock of the Company owned by you or any member of your immediate
family are your shares of Series A Preferred Stock.

         The Company hereby agrees to register the resale by you of the shares
of Common Stock issuable to you upon conversion of the shares of Series A
Preferred Stock owned by you in a registration statement on Form S-3 promptly
after the Company becomes eligible to use such form. The Company agrees to keep
such registration statement effective

         All of the foregoing is in consideration of your signing the same form
of lock-up agreement which the Underwriters are asking senior management of the
Company to sign. The form of lock-up agreement is attached as Exhibit A hereto.

         To indicate your acceptance of and agreement with the terms set forth
in this letter, please sign this letter and the lock-up agreement and return it

Ladies and Gentlemen:

         This letter is being delivered to you in connection with the proposed
Underwriting Agreement (the "Underwriting Agreement") between CollegeLink.com
Incorporated, a Delaware corporation or any successor (the "Company"), and you
as representative of the several underwriters (the "Underwriters") named in
Schedule I thereto, relating to an underwritten public offering (the "Offering")
of shares of the Company's common stock, $.001 par value per share (the "Common
Stock") (including shares of Common Stock subject to an option granted to the
Underwriters solely to cover over-allotments, if any).

         In order to induce you and the other Underwriters to enter into the
Underwriting Agreement with respect to the Offering, the undersigned, intending
to be legally bound, hereby agrees, for the benefit of the Company, you and the
other Underwriters, that for a period of 180 days following the effective date
of the Registration Statement relating to the Offering (the "Lock-up Period"),
the undersigned will not, without the prior written consent of the

which is designed to, or could be expected to, result in the disposition at
anytime in the future of) ("Transfer") any shares of Common Stock or securities
convertible into or exchangeable for or evidencing any right to purchase or
subscribe for any shares of Common Stock (either pursuant to Rule 144 of the
regulations under the Securities Act of 1933, as amended, or otherwise) either
beneficially owned by the undersigned as of the effective date of the
Registration Statement or acquired by the undersigned during the Lock-up Period
as a result of the exercise of options or otherwise (the "Securities"). The
undersigned also will not, during the Lock-up Period, exercise any registration

of the Representative.

         Further, during the 180-day period immediately following the Lock-up

event, all sales or other dispositions of Common Stock by such parties will be
made through Cruttenden Roth Incorporated as Representative, subject to the

180-day period, whichever occurs first.

undersigned hereby agrees that, during the Lock-up Period and for 180 days
thereafter, the execution of any order relating to a Transfer of Securities
shall be placed through the Representative.

covenants, the Undersigned hereby consents to the placing of legends on the
Securities and stop-transfer orders with the transfer agent of the Company's
securities with respect to any of the Securities registered in the name of or
beneficially owned by the undersigned.

accordance with the laws of the State of Delaware without giving effect to the
choice of law or conflict of laws principles,
