        WHEREAS, the Company is an online retailer of pet products, information
and resources;

        WHEREAS, Petstore.com, Inc., a Delaware corporation ("Petstore"), and
the Company are parties to that certain Asset Purchase Agreement dated of even
date herewith (the "Purchase Agreement"), pursuant to which the Company is
purchasing the assets of Petstore (the "Purchase");

        WHEREAS, on April 6, 2000 DCOM terminated that certain (a) Content and
Trademark Sublicense and Services Agreement between DCOM and Petstore, dated as
of October 27, 1999, and (b) Advertising and Promotion Agreement between DCOM
and Petstore, dated as of October 27, 1999; and

        WHEREAS, DCOM and Company have agreed, strictly conditioned and
effective solely upon the closing of the Purchase in accordance with the
Purchase Agreement, to enter into this Tenancy and Promotion Agreement.

        NOW, THEREFORE, in consideration of the foregoing, and for other
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto hereby agree as follows:

        1. GENERAL DEFINITIONS. As used in this Agreement, the following terms
shall have the following respective meanings:

               1.1 "Ad Placement" shall have the meaning set forth in Paragraph
2.2(b).

               1.2 "Ad Spots" shall have the meaning set forth in Paragraph
2.2(a)(i).

               1.3 "Affiliate" shall mean any Person that directly or indirectly

supplies is not P&G's principal business.) Upon written notice to DCOM, the

computer networks, each using the Transmission Control Protocol/Internet
Protocol and/or such other standard network interconnection protocols as may be

timing and placement of promotion of the Website shall be subject to
availability and shall be at the reasonable discretion of DCOM. The actual costs
incurred by DCOM or paid by DCOM to third parties for producing any
advertisements or promotions, if any are incurred by DCOM, shall be at a
mutually agreed upon (between DCOM and the Company) written rate and shall be,
as agreed upon in writing by the parties, either (i) reimbursed by the Company
on a fairly allocated basis taking into consideration the overall message of the
advertisement and the portion thereof directed toward the promotion of the
Website, or (ii) shall be applied on a fairly allocated basis to the aggregate
value of the

Promotion delivered to the Company by DCOM pursuant to this Agreement. DCOM will
not incur any such production costs without the prior written approval of
Company, provided Company may not withhold approval of such costs solely in an
effort to cause DCOM to breach its obligations under this Agreement. It is
understood that such production costs will be incurred by DCOM only to the
extent that the Company and DCOM agree to develop new creative for either the
Co-branded Ads or the Ad Spots or the parties agree to integrate the Pets.com
brand, trademarks or other messaging into the Co-branded Ads in a new or
non-traditional format.

               2.2 Delivery of Advertising and Promotion.

                      (a) The Promotion to be delivered pursuant to this
Agreement shall be delivered as follows:

                             (i) Approximately [*] per Contract Year in
Company-branded interstitial advertising spots for Company and the Website shall
be provided on the Discovery Networks (the "Ad Spots"). The value of each such
Ad Spot shall be determined based on the Prevailing Market Rate (as defined
below) for such Promotions. Subject to the terms and conditions of the Discovery
Networks' standard network sponsorship contracts and any other standard
advertising terms and conditions, the content of such Ad Spots shall be at the
discretion of the Company. Determinations regarding placement of the Ad Spots
shall be subject to availability of inventory and to DCOM's reasonable
discretion.

                             (ii) Approximately [*] per Contract Year in
co-branded interstitial advertising (the "Co-branded Ads") shall be provided on
the Discovery Networks and/or other broadcast media outlets, including without
limitation, broadcast or cable television and radio. The Co-branded Ads shall be
produced by DCOM and shall promote the pets content and commerce portion of the
Discovery.com website, including promotion of the Company as the provider of pet
supplies. Each Co-branded Ad shall be valued at [*] of the Prevailing Market
Rate for such Promotion. The content and placement of the Co-branded Ads shall
be at the sole discretion of DCOM.

                      (b) The value of all Promotion provided hereunder shall be
charged at the "Prevailing Market Rate" for such Promotion, excluding barter,
which will be the market rate less any agency or other commissions (where
applicable) for spots purchased on the Discovery Networks and such other
broadcast stations, networks, cable networks, radio stations or print media
during the time period in which the Promotion occurs. With respect to the
Promotion delivered on the Discovery Networks and DCOM's websites, DCOM will use
commercially reasonable best efforts to obtain marketplace rates at least as
favorable as those provided to third parties making comparable purchases. DCOM
will provide the Company within thirty (30) days after the end of each Contract
Year a statement, certified by an officer of DCOM, summarizing the value of the
Promotion DCOM has delivered for the Website (the "Ad Placements") during such
Contract Year. Each such report shall summarize the Ad Placements delivered over
the

previous Contract Year, the Prevailing Market Rate for such Promotion and the
total value of the Ad Placements provided during such Contract Year. The
Prevailing Market Rate of any particular Ad Placement will be demonstrated by
DCOM upon the Company's request, provided such requests shall not be of an
unreasonable frequency or require an unreasonable level of detail.

               2.3 Subject to availability of inventory (and in the event
designated inventory is unavailable, substitution of substantially equivalent
inventory), the interstitial advertising plan for the first Contract Year is
attached hereto as Attachment A. The parties acknowledge and agree that the
information contained in Attachment A is proprietary and confidential and the
parties agree to maintain it in strict confidence, provided however, the Company
may publish Attachment A to the extent explicitly required by a governmental
agency, in which such event, the Company shall promptly notify DCOM, and the
parties shall cooperate to obtain as much confidential treatment as possible for
Attachment A under the circumstances.

               2.4 Each party agrees to designate and maintain a primary point
of contact regarding interstitial advertising under this Agreement within 30
days of execution of this Agreement.

               2.5 The parties agree to discuss the following additional mutual
promotional initiatives, it being understood that neither party is obligated to
implement any such promotional initiative: e-mail offers to the parties'
respective customer lists, catalog inserts in the Discovery Channel Catalog and
the Company's magazine, in-store promotions, inclusion of in-box promotions in
DCOM and Company boxes and joint sponsorships.

        3.     TERM.

        The term of this Agreement (the "Term") shall begin only upon the
closing of the Purchase provided such closing takes place on or before July 31,
2000 and shall continue in full force and effect for a period of four (4)
consecutive years, unless this Agreement is terminated earlier in accordance
with the terms and conditions stated herein. In the event the closing of the
Purchase does not take place on or before July 31, 2000, or in the event the
Purchase Agreement is terminated in accordance with its terms, this Agreement
shall automatically terminate and the parties shall have no further liability or
obligation to one another in any respect.

        4.     EXCLUSIVE PET SUPPLIES E-COMMERCE TENANCY.

               4.1 DCOM shall provide the Company with a one-year exclusive pet
supplies tenancy (the "Exclusivity Period") pursuant to which the Company shall
be the exclusive retail provider of pet supplies on the websites Discovery.com
and AnimalPlanet.com, with three (3) twelve (12)-month renewal options,
exercisable at the Company's option, upon written notice to DCOM at least ninety
days prior to the end of the preceding twelve (12) month period (the Exclusivity
Period, as may be extended by the Company, is referred to as the "Tenancy
Period"). DCOM shall not include advertisements (advertisements being defined as
buttons or banner advertisements), branded content or promotions (promotions
being defined as gift-with-purchases, dollar- or percentage-off discounts and
free give-aways) of any Company Competitor



                                      -5-
<PAGE>   6

on the [*] during the Tenancy Period or on the [*] under (but apart from) the
Discovery.com web portal solely during the first year of the Term; provided,
however, that the foregoing prohibition shall not apply to (a) run-of-site
banner advertisements of Company Competitors or (b) sponsorships of
network-related programming or content areas by Company Competitors.

               4.2 Except as explicitly provided in Section 4.1, it is
understood and agreed that nothing contained herein shall preclude or in any way
limit DCOM or its affiliated entities, including without limitation the
Discovery Networks, from accepting paid advertising or sponsorships from any
third party advertiser whatsoever, on any media of DCOM or its affiliated
entities. For purposes of the exclusivity described in Section 4.1 above, it is
understood that DCOM may merchandise and sell on Discovery.com or
AnimalPlanet.com animal and pet related: books, videos, clothing, merchandise or
novelty items, including but not limited to such items that contain Discovery
television network or program related logos, trademarks or slogans (for example,
pet training videos and books, Animal Planet Sports frisbees or Travel Channel
pet carriers), provided, however, that such merchandise shall not promote, or
contain branding of, any Company Competitor except to the extent any such item
also contains a trademark or logo of DCOM or its parent or affiliates. Such
animal or pet-related sales by DCOM or its contractors/partners shall be
incidental, i.e., not the principal line of products offered in any area of
Discovery.com or AnimalPlanet.com. The Company acknowledges and agrees that one
of the services provided by Discovery.com, currently in the Web Express area, is
to identify and provide links to other leading websites, including pet
e-commerce sites.

               4.3 The tenancy payment during the first Contract Year will be at
a [*] discount off the "Prevailing E-commerce Tenancy Market Rate" for such
tenancy. The tenancy payment in years [*] of the Tenancy Period, if the
Exclusivity Period is extended by the Company pursuant to Section 4.1, will be
as follows:

                      [*]

               The "Prevailing E-commerce Tenancy Market Rate" as used in this
paragraph shall be the then-prevailing CPM market rate for the actual number of
impressions delivered (subject to the cap described below). The tenancy payment
in years two through four shall be made annually within 30 days of the end of
the applicable Contract Year based on the actual number of impressions delivered
during the preceding 12-month period. The tenancy payment in years two through
four will be capped at the then-prevailing CPM market rate multiplied by the
number of projected impressions set forth in the agreed marketing plan for each
upcoming Contract Year as specified in Section 4.4 below, discounted as
described above in this Section 4.3.

               4.4 During the first Contract Year, DCOM will place promotional
buttons, text links and product promotions throughout Discovery.com and
AnimalPlanet.com as set forth in Attachment B. The parties acknowledge and agree
that the information contained in Attachment B is proprietary and confidential
and the parties agree to maintain it in strict confidence, provided however, the
Company may publish Attachment B to the extent explicitly required by a
governmental agency, in which such event, the Company shall promptly notify
DCOM, and the parties shall cooperate to obtain as much confidential treatment
as possible for Attachment B under the circumstances. The Company acknowledges
and agrees that the specific form, placement and positioning of such buttons,
text links and product promotions may be subject to change, such modifications
to be in DCOM's reasonable discretion, provided that such changes are made in
consultation with the Company and that at any given time during the Tenancy
Period, the volume and configuration of such promotional buttons, text links and
product promotions remain comparable in scope to those listed in Exhibit B. At
least 120 days prior to the end of each Contract Year, DCOM will provide the
Company with a proposed online marketing plan for the upcoming Contract Year.
The parties will negotiate in good faith with respect to such online marketing
plan for the upcoming Contract Year with the goal of finalizing such marketing
plan prior to the latest date by which the Company must exercise its right to
extend the Exclusivity Period for an additional year under Section 4.1, it being
understood that the scope of the proposed online marketing plan for the [*]
Contract Years will be at least as broad in scope as the plan attached hereto as
Exhibit B. The parties acknowledge and agree that the ultimate decisions with
respect to general website design and layout and the specific form, placement
and positioning of the online Company promotions hereunder shall be determined
by DCOM in its reasonable discretion in accordance herewith. In the event
promotional inventory more desirable than the promotional inventory set forth in
the online marketing plan for any Contract Year becomes generally available on
Discovery.com and AnimalPlanet.com, DCOM will consult in good faith with the
Company regarding an opportunity to substitute such promotional inventory.

               4.5 During the Tenancy Period, the Company shall be included as a
branded department [*], appearing throughout Discovery.com. While DCOM may in
its sole discretion modify the placement of the [*] box throughout Discovery.com
and this placement will be subject to change over time, the [*] box currently
has the following placements: [*].

               4.6 DCOM currently anticipates that the [*], including a branded
partner link, will also be added, at DCOM's sole discretion, to other prominent
areas of Discovery.com including the: [*].

               4.7 The promotions set forth in Exhibit B will generally direct
users directly to the Website (except that the unbranded "pets" tab will direct
users to the AnimalPlanet.com website where the Company will have a branded
presence), provided however, the parties agree that DCOM may frame the Website
displaying the top hat and bottom hat navigational bars of

the Discovery.com website when end-users click-through the Company promotions on
Discovery.com to the Website. In addition, with respect to specific product
offers that have been integrated into Discovery.com (including without
limitation AnimalPlanet.com) content pages by mutual agreement of the parties,
DCOM may in its sole discretion create and host bridge pages, product pages or
special offer pages (to be shown to the Company in advance of transmission to
the public) to which the above-described links will direct users (the "Bridge
Pages").

               4.8 Third-party advertising will not be sold on the Bridge Pages
unless and until such Bridge Pages account for at least 5 percent of the total
page views on Discovery.com, in which such event DCOM shall have the sole right
to sell and serve all advertising on the Bridge Pages, provided, however, that
no advertising from a Company Competitor will run on such Bridge Pages except
for any run-of-site banners. All page views on the Bridge Pages shall be
attributed to DCOM.

               4.9 Each party agrees to designate and maintain a primary point
of contact regarding online promotion under this Agreement within 30 days of
execution of this Agreement.

        5.     OBLIGATIONS OF THE COMPANY.

               5.1 User Data. During the Tenancy Period, the Company shall

without limitation AnimalPlanet.com) whereby such users would be given the
option of allowing the Company to provide their personally identifying

shall be jointly owned by DCOM and the Company, and the Company shall deliver
such jointly-owned data on a quarterly basis to DCOM during the Tenancy Period.
The Company shall also [*] upon [*] per [*] during the Tenancy Period to all of
the [*] to the [*] from Discovery.com (including without limitation
AnimalPlanet.com), such [*] to be [*] in DCOM's [*] as to [*], provided however,
that DCOM [*] with the Company with respect to the [*] of such [*] and that any
such [*] DCOM desires to [*] between [*] during any [*] shall be [*] only upon
the [*] of the parties. The Company further agrees that if during the Tenancy
Period the Company amends its privacy policy such that personally identifying
customer data of users of the Website could be provided to a third party, or if
the Company provides any such data to any third party, it will also provide such
data to the same extent to DCOM hereunder. DCOM shall own and have rights to use
customer data of customers driven to the Website from Discovery.com and of
customers who opt in to data

               5.3 Customer Service and Order Fulfillment. The Company shall be
solely responsible for (a) processing and fulfilling all orders made through the
Website, (b) all accounting with respect to such orders, and (c) all customer
service and support with respect to such orders, purchases and returns. The
Company shall provide all of the foregoing services at a very high level of
quality consistent with the Discovery and Animal Planet reputation. The Company
is and shall be solely responsible for the security of any transactions
initiated within the Website. During the Term, the Company shall achieve and
maintain the performance, customer service levels, site reliability requirements
and order fulfillment rates set forth in Attachment C, attached hereto and
incorporated by reference. During the Tenancy Period, DCOM shall achieve and
maintain the site reliability requirements set forth in Attachment D, attached
hereto and incorporated by reference. The Company shall not override the browser
back button functionality to prevent users who link to the Website from
Discovery.com (including without limitation AnimalPlanet.com) from returning to
Discovery.com.

               5.4 Company Content.

                      (a) The Company shall deliver to DCOM the Content
described in Attachment E on a regular basis throughout the Tenancy Period in
accordance herewith. The Company will deliver the Content to DCOM in HTML format
or in such other electronic format as may be mutually agreed, via modem or
Internet access (e.g. Internet ftp or Internet e-mail). The initial delivery of
Content hereunder shall include all items specifically listed on Attachment E
and shall be made by the Company no later than July 31, 2000. The Company will
provide additional Content and update existing Content consistent with the scope
of Content described in Attachment E from time to time during the Tenancy
Period. The Company shall cooperate and assist DCOM by promptly responding to
complaints regarding the Content.

                      (b) DCOM shall integrate the Content into Discovery.com
and AnimalPlanet.com so that it reflects the design, look and feel of the
site/pages where the Content is being integrated, and DCOM shall host the
Content. DCOM shall have the right to edit and make technical and other
alterations to the Content provided that DCOM shall not alter the substantive
meaning of any such Content, except in the event DCOM determines that such
Content requires such substantive modification in order to be accurate, in which
event, DCOM shall notify the Company of such modification. The decision to use
or transmit, the frequency of

transmission and actual placement of the Content shall be at the sole discretion
of DCOM, and DCOM shall have sole editorial control over Discovery.com,
AnimalPlanet.com and DCOM's affiliated websites, including the right to approve
any and all Content displayed on Discovery.com (including without limitation
AnimalPlanet.com) in its sole discretion. DCOM shall post a static textual
attribution to the Company at the top-level page where Content is displayed on
Discovery.com and a dynamic link textual attribution at the lowest-level page or
end of such item of Content. (For example, an article provided to DCOM by the
Company hereunder would carry a static textual attribution at the beginning of
the article on Discovery.com, as well as a dynamic "Find Out More" link at the
end of such article.) Such link would direct users to the Website.

                      (c) Pageviews of the Content on Discovery.com and
AnimalPlanet.com shall be attributed to DCOM, and DCOM shall have the right to
sell all advertising, serve all advertising and retain all revenues earned from
advertising on such pages. DCOM will not place or accept advertisements from
Company Competitors on pages of Discovery.com or AnimalPlanet.com containing
Company Content, provided however that such restriction shall not apply to (a)
run-of-site banner advertisements of Company Competitors or (b) sponsorships of
network-related programming or content areas by Company Competitors.

                      (d) The parties shall each promptly inform the other party
of any material claims that arise with respect to the Content, and provide to
the other party all information in its possession pertaining to such claim.

                      (e) DCOM shall have the right to utilize synopses,
excerpts, headlines or teasers from the Content, for the sole purpose of
advertising, promoting or publicizing the Content, DCOM or Discovery.com
(including AnimalPlanet.com) worldwide, in any media, it being understood that
this promotional right shall not be construed as a right on the part of DCOM to

               9.1 Except as set forth herein, neither party may assign or
otherwise transfer this Agreement, or its respective rights and obligations
hereunder, in whole or in part without the other party's prior written consent.
Any attempt to assign this Agreement (including without limitation transfers by
operation of law or that otherwise result in the rights or obligations of a
party being enjoyed or fulfilled by a third party) without such consent shall be
void and of no effect ab initio; provided, however, that notwithstanding the
foregoing, DCOM may assign this Agreement to an Affiliate thereof without the
Company's prior approval, and, with DCOM's prior written approval, such approval
not to be unreasonably withheld, the Company may assign or otherwise transfer
this Agreement, in whole, solely in connection with a merger, acquisition or
asset sale of all or substantially all of the Company's business, provided
further that Company may assign this Agreement, in whole, solely in a merger,
acquisition or asset sale of all or substantially all of the Company's business
to Amazon.com, provided that there has not occurred a material change in the
business or ownership structure of either Amazon.com or DCOM between the date of
execution of this Agreement and the date of such requested transfer that would
adversely impact DCOM in the event of such transfer. In the event DCOM does not
approve an assignment or transfer by the Company of this Agreement pursuant to a
sale or



                                      -13-

merger with Amazon.com under this Section 9.1, and the Company proceeds with
such merger or sale to Amazon.com, this Agreement shall automatically terminate
without further obligation on the part of either of the parties, provided
however, that in full consideration therefor DCOM may elect in its discretion
either to (a) deliver for the benefit of Amazon.com's pet supplies business the
remainder of the then-remaining Ad Spots due to the Company under Section
2.2(a)(i) hereof; (b) return that number of shares of the Company then held by
DCOM in an amount the share price of which (on the public market, subject to the
Share Price Floor described below) is equal in value to the dollar value then
remaining of DCOM's obligations under Section 2.2(a)(i) hereof, as such
advertising is valued under this Agreement, provided however, (i) the shares to
be returned by DCOM shall be valued for purposes of this Section 9.1 at no less
than the public market price of the Company's shares on the date of this
Agreement (the "Share Price Floor"), and (ii) DCOM shall be required to return
no more than the total amount of shares of the Company then held by DCOM; or (c)
pay to the Company cash for the dollar value then remaining of DCOM's
obligations under Section 2.2(a)(i) hereof, as such advertising is valued under
this Agreement. In addition, DCOM may, at its election, fulfill any obligation
under the immediately preceding sentence with any combination of the options
described in subsections (a), (b) and (c) thereof.

               9.2 If any provision of this Agreement (or any portion thereof)
or the application of any such provision (or any portion thereof) to any Person
or circumstance shall be held invalid, illegal or unenforceable in any respect
by a court of competent jurisdiction, such invalidity, illegality or
unenforceability shall not affect any other provision hereof (or the remaining
portion thereof) or the application of such provision to any other Persons or
circumstances.

               9.3 All notices or other communications required or permitted to
