               BILL OF SALE, ASSIGNMENT AND ASSUMPTION AGREEMENT

          This Bill of Sale, Assignment and Assumption Agreement (this
"Agreement") is made as of March ___, 2000, by and between CAIS Software
Solutions, Inc., a California corporation ("Buyer"), and QuickATM, LLC, a
California limited liability company ("Seller").

                                   RECITALS:

          Pursuant to that certain Asset Purchase Agreement, dated as of March
____, 2000, by and among Seller, Buyer and CAIS Internet, Inc., a Delaware
corporation and the parent company of Buyer (the "Asset Purchase Agreement"),
Buyer has agreed to purchase from Seller and Seller has agreed to sell,
transfer, assign, convey and deliver to Buyer the "Assets" (as such term is
defined in the Asset Purchase Agreement).  All other capitalized terms used, but
not defined, herein shall also have those meanings assigned to them in the Asset
Purchase Agreement.

          NOW, THEREFORE, pursuant to Section 2.1 of the Asset Purchase
Agreement and in consideration of the premises set forth in the Asset Purchase
Agreement and for good and valuable consideration as set forth therein, the
receipt and adequacy of which are hereby acknowledged, Seller and Buyer hereby
agree as follows:

Section 1.  Transfer and Assignment of the Assets.  In accordance with and
            -------------------------------------
subject to all the terms and conditions of the Asset Purchase Agreement, Seller
hereby irrevocably sells, assigns, grants, conveys, transfers and delivers (the
"Transfer") to Buyer, its successors and assigns, all of Seller's right, title
and interest in and to the Assets.

Section 2.  Assumed Liabilities.  In consideration for the Transfer of the
            -------------------
Assets on the date hereof, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Buyer, by this
Agreement, hereby assumes and becomes responsible for all liabilities and
obligations with respect to, and becomes fully responsible for, the Assumed
Liabilities.

Section 3.  Waiver of Moral Rights.  Except to the extent that any such waiver
            ----------------------
is prohibited by law, Seller hereby waives the benefits of any provision of law
known as "moral rights" or any similar law in any country of the world
(including under Section 106A of the U.S. Copyright Act of 1976, as amended) and
agrees not to institute, support, maintain or permit any action or lawsuit on
the ground that any Asset or any version of any Asset used, modified or
exploited by Buyer, its assignees or licensees, in any way constitutes an
infringement of any of Seller's moral rights or is in any way a defamation or
mutilation of such Asset or any part thereof or contains unauthorized
variations, alterations, modifications, changes or translations.

Section 4.  Further Assurances.  If at any time at or after the date hereof
            ------------------
Buyer either considers or is advised that any deed, other instrument of
conveyance or Transfer,
<PAGE>

assignment, assumption or assurance or other documentation or the taking of any
other act is necessary, desirable or proper to vest, perfect or confirm in
Buyer, its successors or assigns, of record or otherwise, the title to any of
the Assets, Seller agrees, at Buyer's expense, to execute and deliver all such
reasonable deeds, instruments, assignments, assumptions, assurances and
documents and to do all things reasonably necessary, desirable or proper to
vest, perfect or confirm title to such Assets in Buyer, its successors or
assigns, and otherwise to carry out the purposes of this Agreement. Seller
agrees, at Buyer's expense, to assist Buyer, its successors or assigns, in every
proper way to protect Buyer's, its successors' or assigns', rights in the Assets
throughout the world, including, without limitation, executing in favor of
Buyer, its successors or assigns, patent, copyright, and other applications and
assignments relating to the Assets.

Section 5.  Seller agrees not to challenge the validity of the ownership by
Buyer, its successors and assigns, of any of the Assets.

Section 6.  Delivery.  Seller hereby represents that all Assets and components
            --------
thereof have been delivered to Buyer as of the date hereof; provided, however,
that from and after the date hereof, if Seller becomes aware of any Asset in its
possession that was not delivered to Buyer as of the date hereof, Seller shall,
at Seller's expense, promptly notify Buyer of any such Asset, and deliver any
such Asset to Buyer in accordance with Buyer's reasonable instructions.
Seller's failure to deliver any Asset hereunder shall, under no circumstances,
give rise to any monetary damages or liability whatsoever under this Agreement,
and Seller's only obligations (and Buyer's only remedy) under this Agreement is
to cause the prompt delivery of such Asset to Buyer.
