Ladies and Gentlemen:


         We have acted as counsel to Cyberian Outpost, Inc., a Delaware
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission (the "Commission") of a Registration
Statement on Form S-3 (the "Registration Statement"), pursuant to which the
Company is registering under the Securities Act of 1933, as amended, 4,702,900
shares of the Company's common stock, $.01 par value per share (the "Shares"),
for resale to the public. The Shares, if and when sold, will be sold by certain
security holders of the Company. This opinion is being rendered in connection
with the filing of the Registration Statement. All capitalized terms used herein
and not otherwise defined shall have the respective meanings given to them in
the Registration Statement.

         In connection with this opinion, we have examined the Company's
Restated Certificate of Incorporation and Restated By-laws, both as currently in
effect, such other records of the corporate proceedings of the Company and
certificates of the Company's officers as we have deemed relevant, and the
Registration Statement and the exhibits thereto.

         In our examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, photostatic or facsimile copies and the
authenticity of the originals of such copies.

         Our opinion is limited to the General Corporation Law of the State of
Delaware (including the applicable provisions of the Delaware Constitution and
the reported judicial decisions interpreting the laws) and the federal laws of
the United States of America, and we express no opinion with respect to the laws
of any other jurisdiction. No opinion is expressed herein with respect to the
qualification of the Shares under the securities or blue sky laws of any state
or any foreign jurisdiction.

Stock, free of preemptive rights.

may hereafter come to our attention or changes in the law which may hereafter
occur. We hereby consent to (i) the reference to this firm under the under the
