Dear Mr. Lipson:

         In order to induce you in your capacity as Receiver of certain entities
which have previously advanced funds to us to forbear from the immediate
collection of such advances, whether through the commencement of suit or
otherwise, we acknowledge and agree as follows:

         1. We acknowledge the receipt of several advances as are set forth on
Schedule A attached hereto and incorporated herein by this reference from
certain entities for which you serve at present as Receiver. We also acknowledge
that interest has accrued on such advances.

         2. Simultaneously with our execution and delivery of this letter, we
are executing and delivering to you a promissory note of even date herewith in
the principal amount of $400,000. The principal amount of $400,000 represents
the advances described on Schedule A as well as interest accrued through April
11, 2000.

         In consideration of the foregoing and our execution and delivery to you
of the promissory note referenced above, you acknowledge that we are not, at
present, in default with respect to our obligations to make payment to you.

         In order to facilitate a resolution of the matters between us, we
acknowledge and agree as follows:

         1. Based on our discussions to date, we recognize that any resolution
of the matters between us will likely involve the issuance by us of securities
to you. Such securities may take the form of a convertible note, warrants,
common stock, or a combination of some or all of the foregoing. We agree that,
in connection with the issuance of any such securities, we will grant to you the
right to cause us at any time and from time to time to register at our expense
the offer and sale of such securities under all applicable federal and state
securities laws.

but in no event later than May 31, 2000.

you, shall be tolled for all purposes during the period commencing on October
27, 1999 and terminating on May 31, 2000.

                      ASSIGNMENT AND ASSUMPTION AGREEMENT

         This Assignment and Assumption Agreement (the "Agreement") is made as
of the 12th day of May, 2000, by, between and among Genuine Golf, LLC
("Assignor"); Philip Kenny ("Kenny"); Brian Mahoney ("Mahoney"); and Beverly
Hills, Ltd. Inc., a Utah corporation ("Assignee").

                                   RECITALS:

         A. Host Services and Nevada Bob's Golf Express of Atlanta ("NBGE")
entered into that certain lease agreement dated November 20, 1997 (the "Lease"),
for the lease by NBGE of two (2) retail store locations (the "Leased Premises")
in the Atlanta Hartsfield International Airport.

         B. Prior hereto, Kenny, on behalf of The Express Group, LLC (the
"Express Group"), entered into an agreement with the principal owners of NBGE
whereby NBGE assigned all of its right, title and interest in and to the Lease
to the Express Group and the Express Group agreed to assume all of NBGE's
obligations under the Lease.

         C. Thereafter but prior hereto, the Express Group entered into an
agreement with Assignor whereby the Express Group assigned all of its right,
title and interest in and to the Lease to Assignor and Assignor agreed to assume
all of the Express Group's obligations under the Lease.

         D. Assignor desires to assign the Lease to Assignee, and Assignee
desires to assume, all of Assignor's right, title and interest in and to the
Lease pursuant to the terms and condition set forth herein.

         E. Kenny and Mahoney are principals of Assignor and join in this
Agreement to confirm the undertakings of the Assignor herein, and certain
collateral undertakings on their part.

                                   AGREEMENT:

         NOW, THEREFORE, in consideration of the mutual promises contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

         1. Assignment. Assignor hereby assigns to Assignee (a) the Lease,
together with all rights, privileges, and easements thereunder or associated
therewith, and all of Assignor's right, title, and interest in and to the Leased
Premises; (b) all Assignor's right, title and interest to open any other golf
retail store locations located in airports throughout the world; and (c)
Assignor's inventory line of credit secured by any and all inventory and
fixtures not to exceed one hundred and fifty thousand dollars ($150,000).

                                       1
<PAGE>   2

         2. Assumption. Subject to Paragraph 3 hereinbelow, Assignee accepts the
assignment and hereby agrees to comply with and be bound by all the terms and
conditions of the Lease and to assume and fulfill all of the obligations of
Assignor under the Lease arising after the date hereof.

         3. Due Diligence. Within ten (10) business days from the date of this
Agreement, Assignor shall furnish to Assignee (a) true and correct copies of the
Lease and any and all related exhibits, addenda, amendments, and modifications,
(b) true and correct copies of the prior agreements and/or assignments by which
NBGE assigned the Lease to the Express Group and the Express Group assigned the
Lease to Assignor (c) detailed and accurate statements of the revenues and
expenses associated with the Lease and the operation of the Leased Premises, and
(d) any other information and documentation which may be material to the Lease
or the operation of the Leased Premises and which may be in the possession of
Assignor. Assignee shall have ten (10) business days from its receipt thereof
within which it may, if not satisfied with the information and documentation
provided, terminate this Agreement by written notice to Assignor, and in such
event none of the parties shall have any further rights or obligations pursuant
hereto. In the absence of such notice, however, it shall be presumed that
Assignee is satisfied with the information and documentation provided, and the
parties shall be and remain bound by this Agreement.

         4. Assignor's Indemnity. Assignor shall indemnify Assignee and hold
Assignee harmless from and against any and all claims, demands, actions,
liabilities, losses, or damages (including reasonable attorneys' fees and costs)
whatsoever arising out of or relating to the Lease and the operation of the
Leased Premises prior to the date hereof.

         5. Assignor's Representations and Warranties. Assignor represents and
warrants to Assignee as follows:

                  (a) The Lease is in full force and effect and has not been
         modified, amended or revoked.

                  (b) All amounts due from Assignor under the Lease through the
         date of this Agreement have been paid or will have been paid by
         Assignor within fifteen (15) days hereafter. Assignor is not delinquent
         in any payment of rent or other amounts due under the Lease.

                  (c) To Assignor's knowledge, there are no defaults by Assignor
         under the Lease or events which with the passage of time or the giving
         of notice would constitute a default under the Lease.

         6. "As Is" Condition. Subject only to Assignee's rights pursuant to
Paragraph 3 above, Assignee acknowledges and agrees that the Premises shall be
delivered to Assignee and Assignee shall accept possession of the same in an "as
is," "where is" condition.

                                       2
<PAGE>   3

         7. Consideration. Assignee is the owner and holder of all of the issued
and outstanding shares of Focus Media Limited, a private limited company
organized and existing under the laws of the Republic of Ireland ("FML"),
subject only to commitments to transfer or issue shares representing in the
aggregate not more than 10% thereof to other parties. FML is the parent company
of Global Golf Limited, a private limited company organized and existing under
the laws of Northern Ireland ("GGL"), which owns and operates the globalgolf.com
Internet web site. As consideration for the Assignor's execution of this
Agreement, Assignee agrees to transfer to Assignor or to cause FML to issue to
Assignor shares of FML's capital stock representing 1.5% of all of FML's capital
stock issued and outstanding.

         In the event that this Agreement shall be terminated by Assignor
pursuant to Paragraph 9 below, Assignor shall be obligated to return said
shares. For such purpose, and if necessary in order to effect a return of said
shares, Assignor hereby irrevocably appoints Assignee as its attorney in fact,
to re-transfer or cancel said shares (as appropriate) on the books and records
of FML, with full power of substitution in the premises.

         8. Covenant as to Further Golf-Related Enterprises. As consideration
for Assignee's execution of this Agreement, Assignor, Kenny and Mahoney jointly
and severally covenant and warrant to Assignee that during the period of three
(3) years commencing on the date of this Agreement, they shall refer to Assignee
any and all proposed business ventures, enterprises and transactions in the golf
industry (whether involving the sale of products and services to golf courses or
country clubs, tee-time reservations, golf-related travel services, or
otherwise, and whether at wholesale, at retail or in e-commerce on the Internet;
but excluding any involvement related to real property assets of golf courses
and/or resort properties whether in construction, finance, consulting or equity
ownership ) which may be presented to them or which may come to their attention,
and that they shall not be directly or indirectly involved in any such ventures,
enterprises or transactions except through or in conjunction with Assignee.
Without limiting the generality of the foregoing, it is agreed that any
golf-related airport stores shall be owned and operated exclusively by Assignee
and/or its affiliates; but Assignor, Kenny and Mahoney reserve the right to own
and operate non-golf related airport stores.

         9. Termination of Assignment. If, during the period commencing on
February 28, 2000 and ending on July 31, 2000, Assignee, FML and GGL shall not
have secured funds for their respective operations totaling, in the aggregate,
at least $2,500,000, then Assignor may at its option terminate this Agreement,
by giving written notice thereof to the Assignee within ten (10) days after the
expiration of said period. In such event all rights under the Lease granted to
Assignee under this Agreement shall immediately re-vest in Assignor as of
Assignee's receipt of the notice. Assignee hereby agrees to execute such other
documents as Assignor may reasonably require in order to obtain the full benefit
of this Paragraph and of Assignee's obligations hereunder.

         10. Litigation. In the event of any litigation arising out of or
relating to this Assignment, the prevailing party, as determined by the Court
having jurisdiction thereof, shall be entitled to recover all costs and
reasonable attorneys' fees incurred in connection with such litigation
including, without limitation, costs and fees incurred in any investigations,
trials, bankruptcies, and appeals.

         11. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective legal
representatives, successors and assigns.

         12. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall
together constitute one and the same instrument.

         11. Governing Law. This Assignment shall be governed in its
construction, interpretation, and performance by the laws of the State of
Illinois, without reference to law pertaining to conflict of laws.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.
