lapse of time or otherwise would constitute an Event of Default, Seller may
request that Buyer purchase receivables and Buyer may, in its sole discretion,
elect to purchase receivables. Seller shall deliver to Buyer an Invoice

     2.2. ACCEPTANCE OF RECEIVABLES. Buyer shall have no obligation to purchase
any receivable listed on an Invoice Transmittal. Buyer may exercise its sole
discretion in approving the credit of each Account Debtor before buying any
receivable. Upon acceptance by Buyer of all or any of the receivables described
on any Invoice Transmittal, Buyer shall pay to Seller 80 (%) percent of the face
amount of each receivable Buyer desires to purchase, net of deferred revenue and
offsets related to each specific Account Debtor. Such payment shall be the
"Advance" with respect to such receivable. Buyer may, from time to time, in its
sole discretion, change the percentage of the Advance. Upon Buyer's acceptance
of the receivable and payment to Seller of the Advance, the receivable shall
become a "Purchased Receivable." It shall be a condition to each Advance that
(i) all of the representations and warranties set forth in Section 6 of this
Agreement be true and correct on and as of the date of the related Invoice
Transmittal and on and as of the date of such Advance as though made at and as
of each such date, and (ii) no Event of Default or any event or condition that
with notice, lapse of time or otherwise would constitute an Event of Default
shall have occurred and be continuing, or would result from such Advance.
Notwithstanding the foregoing, in no event shall the aggregate amount of all
Purchased Receivables outstanding at any time exceed FOUR MILLION DOLLARS
($4,000,000.00).

      2.3. EFFECTIVENESS OF SALE TO BUYER. Effective upon Buyer's payment of an
Advance, and for and in consideration therefor and in consideration of the
covenants of this Agreement, Seller hereby absolutely sells, transfers and
assigns to Buyer, all of Seller's right, title and interest in and to each
Purchased Receivable and all monies due or which may become due on or with
respect to such Purchased Receivable. Buyer shall be the absolute owner of each
Purchased Receivable. Buyer shall have, with respect to any goods related to the
Purchased Receivable, all the rights and remedies of an unpaid seller under the
California Uniform Commercial Code and other applicable law, including the
rights of replevin, claim and delivery, reclamation and stoppage in transit.

     2.4. ESTABLISHMENT OF A RESERVE. Upon the purchase by Buyer of each
Purchased Receivable, Buyer shall establish a reserve. The reserve shall be the
amount by which the face amount of the Purchased Receivable exceeds the Advance
on that Purchased Receivable (the "Reserve"); provided, the Reserve with respect
to all Purchased Receivables outstanding at any one time shall be an amount not
less than 20 (%) percent of the Account Balance at that time and may be set at a
higher percentage at Buyer's sole discretion. The reserve shall be a book
balance maintained on the records of Buyer and shall not be a segregated fund.

3.  COLLECTIONS, CHARGES AND REMITTANCES.

     3.1. COLLECTIONS. Upon receipt by Buyer of Collections, Buyer shall
promptly credit such Collections to Seller's Account Balance on a daily basis;
provided, that if Seller is in default under this Agreement, Buyer shall apply
all Collections to Seller's Obligations hereunder in such order and manner as
Buyer may determine. If an item of collection is not honored or Buyer does not
receive good funds for any reason, the amount shall be included in the Account
Balance as if the Collections had not been received and Finance Charges under
Section 3.2 shall accrue thereon.

     3.2. FINANCE CHARGES. On each Reconciliation Date Seller shall pay to Buyer
a finance charge in an amount equal to 1.75(%) percent per month of the average
daily Account Balance outstanding during the applicable Reconciliation Period
(the "Finance Charges"). Buyer shall deduct the accrued Finance Charges from the
Reserve as set forth in Section 3.5 below.

     3.3. ADMINISTRATIVE FEE. On each Reconciliation Date Seller shall pay to
Buyer an Administrative Fee equal to .75 (%) percent of the face amount of each
Purchased Receivable first purchased during that Reconciliation Period (the
"Administrative Fee"). Buyer shall deduct the Administrative Fee from the
Reserve as set forth in Section 3.5 below.

     3.4. ACCOUNTING. Buyer shall prepare and send to Seller after the close of
business for each Reconciliation Period, an accounting of the transactions for
that Reconciliation Period, including the amount of all Purchased Receivables,
all Collections, Adjustments, Finance Charges, and the Administrative Fee. The
accounting shall be deemed correct and conclusive unless Seller makes written
objection to Buyer within thirty (30) days after the Buyer mails the accounting
to Seller.

     3.5. REFUND TO SELLER. Provided that there does not then exist an Event of
Default or any event or condition that with notice, lapse of time or otherwise
would constitute an Event of Default, Buyer shall refund to Seller by check
after the Reconciliation Date, the amount, if any, which Buyer owes to Seller at
the end of the Reconciliation Period according to the accounting prepared by
Buyer for that Reconciliation Period (the "Refund"). The Refund shall be an
amount equal to:

         (A) (1)  The Reserve as of the beginning of that Reconciliation Period,
                  PLUS
             (2)  the Reserve created for each Purchased Receivable purchased
                  during that Reconciliation Period, MINUS
         (B) The total for that Reconciliation Period of:
             (1) the Administrative Fee;
             (2) Finance Charges;
             (3) Adjustments;
             (4) Repurchase Amounts, to the extent Buyer has agreed to accept
                 payment thereof by deduction from the Refund;
             (5) the Reserve for the Account Balance as of the first day of the
                 following Reconciliation Period in the minimum percentage set
                 forth in Section 2.4 hereof; and

                                                                     Page 2 of 8

             (6) all amounts due, including professional fees and expenses, as
                 set forth in Section 12 for which oral or written demand has
                 been made by Buyer to Seller during that Reconciliation Period
                 to the extent Buyer has agreed to accept payment thereof by
                 deduction from the Refund. In the event the formula set forth
                 in this Section 3.5 results in an amount due to Buyer from
                 Seller, Seller shall make such payment in the same manner as
                 set forth in Section 4.3 hereof for repurchases. If the formula
                 set forth in this Section 3.5 results in an amount due to
                 Seller from Buyer, Buyer shall make such payment by check,
                 subject to Buyer's rights under Section 4.3 and Buyer's rights
                 of offset and recoupment.

time or otherwise would constitute an Event of Default, the excess shall be

15. SUBROGATION AND SIMILAR RIGHTS. Notwithstanding any other provision of this
Agreement or any other Document, each Seller irrevocably waives all rights that
it may have at law or in equity (including, without limitation, any law
subrogating the Seller to the rights of Buyer under the Documents) to seek
contribution, indemnification, or any other form of reimbursement from any other
Seller, or any other Person now or hereafter primarily or secondarily liable for
any of the Obligations, for any payment made by the Seller with respect to the
Obligations in connection with the Documents or otherwise and all rights that it
might have to benefit from, or to participate in, any security for the
Obligations as a result of any payment made by the Seller with respect to the
Obligations in connection with the Documents or otherwise. Any agreement
providing for indemnification, reimbursement or any other arrangement prohibited
under this Section shall be null and void. If any payment is made to a Seller in
contravention of this Section, such Seller shall hold such payment in trust for
Buyer and such payment shall be promptly delivered to Buyer for application to
the Obligations, whether matured or unmatured.

16. WAIVERS OF NOTICE. Each Seller waives notice of acceptance hereof; notice of
the existence, creation or acquisition of any of the Obligations; notice of an
Event of Default; notice of the amount of the Obligations outstanding at any

adverse change in the financial condition of any other Seller or of any other
fact that might increase the Seller's risk; presentment for payment; demand;
protest and notice thereof as to any instrument; default; and all other notices
and demands to which the Seller would otherwise be entitled. Each Seller waives
any defense arising from any defense of any other Seller, or by reason of the
cessation from any cause whatsoever of the liability of any other Seller.
Buyer's failure at any time to require strict performance by any Seller of any
provision of the Documents shall not waive, alter or diminish any right of Buyer
thereafter to demand strict compliance and performance therewith. Nothing
contained herein shall prevent Buyer from foreclosing on the lien of any deed of
trust, mortgage or other security instrument, or exercising any rights available
thereunder, and the exercise of any such rights shall not constitute a legal or
equitable discharge of any Seller. Each Seller also waives any defense arising
from any act or omission of Buyer that changes the scope of the Seller's risks
hereunder. Each Seller hereby waives any right to assert against Buyer any
defense (legal or equitable), setoff, counterclaim, or claims that such Seller
individually may now or hereafter have against another Seller or any other
Person liable to Seller with respect to the Obligations in any manner or
whatsoever.

17. SUBROGATION DEFENSES. Each Seller hereby waives any defense based on
impairment or destruction of its subrogation or other rights against any other
Seller and waives all benefits which might otherwise be available to it under
California Civil Code Sections 2809, 2810, 2819, 2839, 2845, 2848, 2850, 2899
and 3433 and California Code of Civil Procedure Sections 580a, 580b, 580d and
726, as those statutory provisions are now in effect and hereafter amended, and
under any other similar statutes now and hereafter in effect.

18. RIGHT TO SETTLE, RELEASE. The liability of Sellers hereunder shall not be
diminished by (i) any agreement, understanding or representation that any of the
Obligations is or was to be guaranteed by another Person or secured by other
property, or (ii) any release or unenforceability, whether partial or total, or
rights, if any, which Seller may now or hereafter have against any other Person,
including another Seller, or property with respect to any of the Obligations.

         Without notice to any Seller and without affecting the liability of any
Seller hereunder, Buyer may (i) compromise, settle, renew, extend the time for
payment, change the manner or terms of payment, discharge the performance of,
decline to enforce, or release all or any of the Obligations with respect to a
Seller, (ii) grant other indulgences to a Seller in respect of the Obligations,
(iii) modify in any manner any documents, relating to the Obligations with
respect to a Seller, (iv) release, surrender or exchange any deposits or other
property securing the Obligations, whether pledged by a Seller or any other
Person, or (v) compromise, settle renew, or extend the time for payment,
discharge the performance of, decline to enforce, or release all or any
obligations of any guarantor, endorser or other Person who is now or may
hereafter be liable with respect to any of the Obligations.

19. JURY TRIAL. SELLER AND BUYER EACH HEREBY (a) WAIVE THEIR RESPECTIVE RIGHTS
TO A JURY TRIAL ON ANY CLAIM OR ACTION ARISING OUT OF OR IN CONNECTION WITH THIS

from the date hereof, and from year to year thereafter unless terminated in
writing by Buyer or Seller. Seller and Buyer shall each have the right to
terminate this Agreement at any time. Notwithstanding the foregoing, any
termination of this Agreement shall not affect Buyer's security interest in the
Collateral and Buyer's ownership of the Purchased Receivables, and this
Agreement shall continue to be effective, and Buyer's rights and remedies
hereunder shall survive such termination, until all transactions entered into
and Obligations incurred hereunder or in connection herewith have been completed
and satisfied in full.

21. TITLES AND SECTION HEADINGS. The titles and section headings used herein are
for convenience only and shall not be used in interpreting this Agreement.

                                                                    Page 7 of 8

and effect notwithstanding the execution of this Agreement. In the event of a
conflict between any provision of this Agreement and any provision of any other
document, instrument or agreement between Seller on the one hand, and Buyer or
any other division or affiliate of Silicon Valley Bank on the other hand, Buyer
shall determine in its sole discretion which provision shall apply. Seller
acknowledges specifically that any security agreements, liens and/or security
interests currently securing payment of any obligations of Seller owing to Buyer
or any other division or affiliate of Silicon Valley Bank also secure Seller's
obligations under this Agreement, and are valid and subsisting and are not
adversely affected by execution of this Agreement. Seller further acknowledges
that (a) any collateral under other outstanding security agreements or other
documents between Seller and Buyer or any other division or affiliate of Silicon
Valley Bank secures the obligations of Seller under this Agreement and (b) a
default by Seller under this Agreement constitutes a default under other
outstanding agreements between Seller and Buyer or any other division or
affiliate of Silicon Valley Bank.

     IN WITNESS WHEREOF, Seller and Buyer have executed this Agreement on the
day and year above written.

                                                                   Exhibit 10.13

                     SETTLEMENT AGREEMENT AND MUTUAL RELEASE

         This Settlement Agreement and Mutual Release, dated as of May 24, 2001
(this "Agreement"), is between CNET Networks Inc., a Delaware corporation, with
a business address at 150 Chestnut Street, San Francisco, California 94111
("CNET"), and deltathree, Inc., a Delaware corporation, with a business address
at 75 Broad Street, New York, NY 10004 ("Delta Three").

         Delta Three and CNET are parties to that certain CNET Promotion
Agreement, dated as of September 22, 1999 (as amended by the First Amendment,
dated June 5, 2000, the "Promotion Agreement"), pursuant to which the Delta
Three agreed to provide its PC-to-telephone connection product and related
services to users of the CNET Sites (as such term is defined in the Promotion
Agreement), and CNET agreed to provide various promotional opportunities to
Delta Three. All capitalized terms without definition herein shall have the
meaning ascribed to them in the Marketing Agreement.

         Delta Three was required to pay CNET a total of $11,000,000 for the
Promotions to be run on the CNET Sites.

         The parties now wish to resolve any and all actual and potential
disputes between them regarding the Marketing Agreement, and therefore agree as
follows:

         1.       SETTLEMENT

                  (a) PAYMENT BY DELTA THREE. Within two business days of the
date hereof, Delta Three shall deliver by wire transfer of immediately available
funds to the account set forth on Exhibit A hereto, an amount equal to
$1,750,000 in full satisfaction of any and all obligations, whether actual or
alleged of Delta Three to CNET under the Promotion Agreement. In the event that
Delta Three fails to pay such amount within two business days of the date
hereof, CNET shall be entitled to pursue all of its rights and remedies
available to it under the Promotion Agreement and to seek payment for all
amounts that accrued to CNET under the Promotion Agreement.

                  (b) MEDIA PLACEMENTS. Subject to Delta Three delivering the
payment described in paragraph 1(a), CNET shall provide Delta Three with media
placements on the CNET Sites valued at $250,000 (at a 30% discount of standard
rate card rates) for Delta Three's products and services. Such media placements
shall appear on the CNET Sites in such locations as determined by Delta Three,
subject to availability, prior to June 30, 2001, and in accordance with an
insertion order to be executed by Delta Three and delivered to CNET on or before
June 1, 2001. If Delta Three fails to deliver the payment in paragraph 1(a) or
fails to execute the insertion order and deliver it to CNET on or before June 1,
2001, CNET shall not be obligated to provide the media placements to Delta Three
as described hereunder.

                  (c) CNET AD BUY. Subject to Delta Three delivering the payment
described in paragraph 1(a) and such payment not being set aside for any reason,
CNET agrees to purchase $250,000 worth of advertising on the Delta Three Site
(at a 30% discount of Delta Three's standard rate card rates) during the third
quarter of calendar year 2001. Payment for such advertising shall be in
accordance with Delta Three's standard terms and conditions.

         2. MUTUAL RELEASES OF ALL CLAIMS. CNET and Delta Three release and
discharge one another and each of their respective affiliated, subsidiary, and
parent corporations, successors, assigns, officers, directors, partners,
employees, agents, servants, representatives, and attorneys, and each of them,
from any and all claims, debts, and causes of action of whatsoever kind and
nature whether known or unknown, arising out of, or in connection with anything
whatsoever done, omitted, or suffered to be done prior to the date of this
instrument, based on, arising out of, or in connection with the actual or
potential claims asserted in, arising out of, relating in any way to, the
Promotion Agreement.

         The release set forth herein extends to all rights of each releasor
under Section 1542 of the California Civil
<Page>

Code and any similar law in any state or territory of the United States, which
are hereby expressly waived by each party hereto.

         Section 1542 of the Civil Code of the State of California reads as
follows:

                           "A general release does not extend to claims which
                  the creditor does not know or suspect to exist in his favor at
                  the time of executing the release, which if known by him must
                  have materially affected his settlement with the debtor."

         Each of the parties to this Agreement waives and relinquishes all
rights and benefits afforded by Section 1542 of the Civil Code of the State of
California. Each party understands that the facts in respect of which the
release made in this Agreement is given may hereafter turn out to be other than
or different from the facts in that connection now known or believed by each
party to be true; and each party hereby accepts and assumes the risk of the
facts turning out to be different and agrees that this Agreement shall be and
remain in all respects effective and not subject to termination or rescission by
virtue of any such difference in facts.

         Each of the parties hereby acknowledges and agrees that nothing
contained in this Agreement shall release or discharge any of them from any
claims arising out of the rights, duties and obligations assumed under this
Agreement, any violation of the surviving provisions of the Promotion Agreement
that arises after the effective date of this Agreement, or any CNET claim
arising from its capacity as a Delta Three shareholder.

         DELTA THREE HEREBY ACKNOWLEDGES AND AGREES THAT THE RELEASE AND
DISCHARGE OF DELTA THREE IS SPECIFICALLY CONTINGENT UPON CNET'S RECEIPT OF THE
PAYMENT SET FORTH IN PARAGRAPH 1(A) ABOVE AND THE PAYMENT NOT BEING SET ASIDE
FOR ANY REASON INCLUDING AS A TRANSFER VOIDABLE UNDER TITLE 11 OF THE UNITED
STATES CODE. In the event that CNET does not receive the payment in paragraph
1(a) or such payment is set aside, the release of Delta Three set forth in this
paragraph 2 shall be null and void and CNET shall have the right to pursue all
rights and remedies available under the Promotion Agreement and seek payment for
all amounts accrued to CNET under the Promotion Agreement.

         3. NO PRIOR ASSIGNMENT OF CLAIMS. Each party represents that it has not
heretofore assigned or transferred, or purported to assign or transfer any claim
or right as against another party to any other person not a party hereto and is
fully entitled to compromise and settle same. Each of the parties to this
Agreement further agrees to indemnify and hold harmless any other party from and
against any claim, debt, liability, demand, obligation, costs, expanse, damages,
action, or cause of action, including reasonable attorney's fees and costs
incurred, arising out of, or in connection with any such assignment or transfer
by him.

         4. NEW YORK LAW. All questions with respect to the construction of this
Agreement and the rights and liabilities of the parties hereto shall be governed
by the laws of the State of New York.

         5. NO OTHER REPRESENTATIONS. Each party acknowledges that, except as
herein expressly set forth, no representations of any kind or character have
been made to it by the other party, or by any of the other party's agents,
representatives, or attorneys, to induce the execution of this Agreement.

         6. OWN COUNSEL. Each party acknowledges that it has been had an
opportunity to be represented by counsel of its own choice throughout all of the
negotiations which preceded the execution of this Agreement and in connection
with the preparation and execution of this Agreement.

         7. NO ADMISSIONS. Each party acknowledges that this Agreement effects
the settlement of claims which are denied and contested by the other party, and
that nothing contained herein shall be construed as an admission of liability by
or on behalf of either party, by whom liability is expressly denied.
<Page>

         8. COVENANT NOT TO SUE. Each party agrees that it will forever refrain
and forebear from commencing, instituting or prosecuting any lawsuit, action or
other proceeding against the other party, based on, arising out of, or in
connection with any claim, debt, liability, demand, obligation, cost, expenses,
action or cause of action that is released and discharged by reason of this
Agreement.

         9. COUNTERPARTS. This Agreement may be executed in separate
counterparts and shall become effective when such separate counterparts have
been exchanged between all of the parties.

         10. HEADINGS. Section headings are for convenience only and are not a
Part of this Agreement.

         11. ATTORNEY'S FEE. The parties agree that each party shall bear their
own attorney's fees and costs arising from the preparation of this Agreement and
performing all acts necessary to implement this Agreement. However, should any
action be brought to enforce the terms or provisions of this Agreement, the
prevailing party therein shall be entitled to an award of reasonable attorney's
fees and costs incurred thereby.

         12. ENTIRETY OF AGREEMENT. The foregoing (including Exhibit A which is
incorporated herein by reference) constitutes the entire Agreement among the
parties hereto with respect to the subject matter hereof and may not be modified
except in a writing signed by all parties hereto.

         IN WITNESS WHEREOF, the parties hereto have caused this Settlement
Agreement and Release to be duly executed as of the day and year first above
written.
