                               EXCHANGE AGREEMENT


         This Exchange Agreement (this "AGREEMENT") is made and entered into as
of September 18, 2000 by and among Meridian Associates, L.P. ("MERIDIAN"), HSA
Properties, Inc., a Delaware corporation ("HSA PROPERTIES"), Michael A. Leven,
Andrea Leven, Jonathan Leven, Robert Leven, and Adam Leven (collectively, the
"LEVEN FAMILY"), and USFS Acquisition Co., a Delaware corporation ("NEWCO").

                                    RECITALS

         SDI, Inc., a Nevada corporation, Newco, HSA Properties, Meridian, and
U.S. Franchise Systems Inc., a Delaware corporation (the "Company"), are parties
to an Acquisition Agreement dated as of September 18, 2000 (the "ACQUISITION
AGREEMENT"), which contemplates the acquisition of the Company by Newco. In
connection with the consummation of the transactions contemplated by the
Acquisition Agreement, Meridian, HSA Properties and the Leven Family
(collectively, the "SUBSCRIBERS" and individually, a "SUBSCRIBER") desire to
transfer shares of capital stock of the Company to Newco in exchange for shares
of capital stock of Newco, all on the terms and subject to the conditions set
forth herein.

         For federal income tax purposes, it is intended that, but such
transactions shall not be conditioned upon, the transactions provided for herein
shall qualify as a transfer to a corporation controlled by transferor within the
meaning of Section 351(a) of the Internal Revenue Code of 1986, as amended (the
"CODE").

                                    AGREEMENT

         For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereby agree as follows:

         1.    DEFINED TERMS. Capitalized words used in this Agreement as
defined terms shall have the meanings given to them in the Acquisition
Agreement, unless otherwise defined herein.

         2.    SUBSCRIPTION.

         2.1   Effective as of the Expiration Date, if Newco purchases such
number of Shares, that together with the Company's Shares owned by the Investors
and its affiliates, represents a majority of the Company's outstanding Shares
(the "Minimum Condition"), pursuant to and in accordance with the Offer, each
Subscriber respectively, shall assign and transfer to Newco the number of shares
of common stock of the Company set forth on Appendix 1 hereto, in exchange for
the number of shares of common stock of Newco ("Newco Stock") set forth on
Appendix 1 hereto.

<PAGE>

         2.2   This Agreement constitutes the irrevocable subscription of each
Subscriber to acquire the Newco Stock in exchange for Shares on the terms
and subject to the conditions set forth in this Agreement. Newco accepts all
such subscriptions on the terms and subject to the conditions set forth in this
Agreement.

         2.3   Upon the issuance of Newco Stock in exchange for Shares, the
Subscribers shall execute and deliver a Stockholders Agreement in the form of
Appendix 2 hereto.

         3.    TERMINATION. Notwithstanding the foregoing, this Agreement shall
cease to be effective if: (a) the Offer shall have expired in accordance with
its terms without the acceptance for purchase of the Minimum Condition pursuant
thereto, (b) the Offer shall have been terminated or withdrawn for any reason,
(c) the Acquisition Agreement is earlier terminated for any reason in accordance
with Article 9 thereof or otherwise, (d) the Offer shall have been amended or
otherwise modified in any material respect (other than the extension of the time
for tenders of Shares), including, without limitation, to reduce the number of
Shares which Newco is offering to purchase or the price at which Newco will
purchase Shares pursuant thereto, or (e) the Board of Directors of the Company
shall have recommended to stockholders or shall have authorized or approved an
Alternative Proposal.

         4.    SUBSCRIBERS' REPRESENTATIONS AND WARRANTIES. Each Subscriber (for
itself, himself or herself and not for the others) represents and warrants to,
and covenants with, Newco and each other Subscriber as follows:

         4.1   The Subscriber is an "accredited investor" as that term is
defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

         4.2   If a natural person, the Subscriber is a bona fide resident of
the state contained in the address set forth on the signature page of this
Agreement and is legally competent to execute this Agreement. If an entity, the
Subscriber is duly authorized to execute this Agreement and this Agreement
constitutes the legal, valid and binding obligation of the Subscriber
enforceable against the Subscriber according to its terms.

         4.3   Regarding Newco and the Company, its business, plans and
financial condition, the terms of the offering and the risks associated
therewith, and any other matters relating to this Agreement, the Subscriber has
received all materials which have been requested by the Subscriber; has had a
reasonable opportunity to ask questions of Newco and the Company and their
representatives; and Newco and the Company have answered all inquiries that the
Subscriber or the Subscriber's representatives have put to it. The Subscriber
has had access to all additional information, and has taken all the steps
necessary to evaluate the merits and risks of an investment in Newco.

         4.4   The Subscriber has, and reasonably can be assumed to have, such
knowledge and experience in finance, securities, investments and other business
matters that the Subscriber is capable of utilizing the information that is
available to the Subscriber concerning


                                      -2-
<PAGE>

Newco and the Company to evaluate the risks of investment in Newco and
understands and acknowledges that (a) this investment is suitable only for an
investor who is able to bear the economic consequences of losing his, her or its
entire investment, (b) the acquisition of the Newco Stock is a speculative
investment which involves a high degree of risk of loss of the entire
investment, (c) any predictions or projections as to Newco's or the Company's
future performance are necessarily subject to a high degree of uncertainty, and
that Newco makes no representations or warranties as to the realization of such
predictions or projections, and (d) there are substantial restrictions on the
transferability of, and there will be no public market for, the Newco Stock, and
accordingly, it may not be possible for the Subscriber to liquidate his, her or
its investment in the Newco Stock at a time when it may be desirable to do so,
or at any other time.

         4.5   The Subscriber confirms that he, she or it is able (a) to bear
the economic risk of this investment, (b) to hold the Newco Stock for an
indefinite period of time, and (c) afford a complete loss of Subscriber's
investment; and the Subscriber has sufficient liquid assets so that the
illiquidity associated with this investment will not cause any undue financial
difficulties or affect the Subscriber's ability to provide for his, her or its
current needs and possible financial contingencies, and that the Subscriber's
commitment to all speculative investments (including this one) is reasonable in
relation to the Subscriber's net worth and/or annual income.

         4.6   The Subscriber is acquiring the Newco Stock for the Subscriber's
own account, for investment purposes only, not for the account of any other
person, and not with a view to the sale or distribution thereof or the granting
of any participation therein, and has no present intention of distributing or
selling to others any of such interest or granting participations therein. The
Subscriber does not have any contract, undertaking, agreement or arrangement
with any person to sell, transfer or grant participations to such person or to
any third person, with respect to the Newco Stock.

         4.7   The Subscriber is aware that the Newco Stock has not been
registered under the Securities Act or any state or foreign securities or "blue
sky" laws, that the Newco Stock will be issued on the basis of the statutory
exemption provided by Section 4(2) of the Securities Act, relating to
transactions by an issuer not involving any public offering and under similar
exemptions under certain state securities or "blue sky" laws, that this offering
has not been reviewed by, passed on or submitted to any federal or state agency
or self-regulatory organization where an exemption is being relied upon, and
that Newco's reliance thereon is based, in part, upon the truth, completeness
and accuracy of the representations made by the Subscriber in this Agreement.

         4.8   The Subscriber acknowledges that it is familiar with the nature
of the limitations imposed by the Securities Act and the rules and regulations
thereunder on the transfer of securities. In particular, the Subscriber agrees
that no sale, assignment or transfer of any Newco Stock by the Subscriber shall
be valid or effective, and Newco shall not be required to give any effect to
such sale, assignment or transfer, unless: (a) (i) such sale, assignment or


                                      -3-
<PAGE>

transfer is registered under the Securities Act and applicable state securities
or "blue sky" laws (collectively, "SECURITIES LAWS"), it being understood that
the Newco Stock is not currently registered for sale and that Newco has no
obligation or intention to so register the Newco Stock, or (ii) the Newco Stock
is sold, assigned or transferred in accordance with all the requirements and
limitations of Rule 144 under the Securities Act, it being understood that Rule
144 is not available at the present time for the sale of the Newco Stock, or
(iii) such sale, assignment or transfer is otherwise exempt from the
registration requirements of Securities Laws; and (b) such sale, assignment or
transfer is in compliance with any applicable agreement by and among Newco and
any one or more of the Subscribers relating to the Newco Stock. The Subscriber
consents that Newco may, if it desires, permit the transfer of the Newco Stock
out of his, her or its name only when the request for transfer is accompanied by
an opinion of counsel, which counsel and opinion are reasonably satisfactory to
counsel to Newco, that neither the sale nor the proposed transfer results in a
violation of Securities Laws.

         4.9   The Subscriber acknowledges that the certificates evidencing the
Newco Stock shall bear the following, or substantially similar legends, and such
other legends may be required by state securities or "blue sky" laws:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS

         TERMS OF THE STOCKHOLDERS' AGREEMENT, WHICH PROVIDES, AMONG OTHER
         THINGS, THAT UNDER SPECIFIED CIRCUMSTANCES THE COMPANY AND OTHER
         SPECIFIED PERSONS HAVE THE RIGHT TO PURCHASE SUCH SHARES FROM THE
         HOLDER THEREOF."

         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE

         NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD,
         PLEDGED, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION
         STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT
         AND ANY APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS, OR (2) THE
         COMPANY RECEIVES AN OPINION OF COUNSEL TO THE HOLDER OF SUCH
         SECURITIES, WHICH COUNSEL AND OPINION ARE REASONABLY SATISFACTORY TO
         COUNSEL TO THE COMPANY, THAT SUCH SECURITIES MAY BE OFFERED, SOLD,

         PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER CONTEMPLATED WITHOUT AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR APPLICABLE
         STATE SECURITIES OR "BLUE SKY" LAWS."

         4.10  The Subscriber acknowledges that this offering may involve tax
consequences and that he, she or it is not relying on any statements or
representations of Newco or any of its agents, employees or affiliates with
respect to the tax and other economic considerations of an investment in the
Newco Stock and acknowledges that the Subscriber must retain his, her or its own
professional advisors to evaluate the federal, state and local tax and other
economic considerations of an investment in the Newco Stock. The Subscriber also
acknowledges that he, she or it is solely responsible for any of his, her or its
own tax liability that may arise as a result of this investment or the
transactions contemplated by this Agreement.

         4.11  The Subscriber confirms that, except as expressly set forth in
this Agreement, no representations or warranties have been made to the
Subscriber by Newco or any agent, employee or affiliate of Newco, and in
entering into this transaction, the Subscriber is not relying on any
information, other than the results of independent investigation by the
Subscriber.

         4.12  The Subscriber is the record and beneficial owner of the Shares
listed opposite his, her or its name on Schedule 1 and will assign such Shares
to Newco on the terms and subject to the conditions set forth in this Agreement
free and clear of all liens, claims, and encumbrances.

         5.    REPRESENTATIONS AND WARRANTIES OF NEWCO. Newco represents and
warrants to each Subscriber as follows:

         5.1   Newco is a corporation duly organized, existing and in good

         5.3   News has furnished to each subscriber a complete and correct copy
of its Certificate of Incorporation and By-Laws. Newco is not in violation of or
default under, nor will the execution and delivery of this Agreement, the
issuance of the Newco Stock, and the incurrence of the obligations herein set

Incorporation or By-laws, any material obligation, agreement, covenant or
condition contained in any agreement or instrument to which Newco is a party or
by which it or any of its properties may be bound or any material order, rule,
regulation, writ, injunction or decree of any government, governmental
instrumentality or court, domestic or foreign.

have outstanding (a) any rights (either preemptive or otherwise) or options to
subscribe for or purchase, or any warrants or other agreements providing for or
requiring the issuance of, any capital stock or any securities convertible into
or exchangeable for Newco's capital stock, (b) any obligation to repurchase or
otherwise acquire or retire any of its capital stock, any securities convertible
into or exchangeable for its capital stock or any rights, options or warrants
with respect thereto, (c) any rights that require Newco to register the offering
of any of its securities under the Securities Act or (d) any restrictions on
voting any of Newco's securities.

         5.5   No litigation or proceeding before, or investigation by, any
foreign, federal, state or municipal board or other governmental or
administrative agency or any arbitrator is currently pending or, to the
knowledge of Newco, threatened against Newco or, to Newco's knowledge, any
officer of Newco, which seeks rescission of, seeks to enjoin the consummation
of, or which questions the validity of, this Agreement or any of the
transactions contemplated by the Acquisition Agreement.

The rights and obligations of each Subscriber hereunder are not assignable, and
any purported assignments shall be void.

         7.3   HEADINGS. The headings in this Agreements are solely for
convenience of reference and shall be given no effect in the construction or
interpretation of this Agreement.

         7.4   CHOICE OF LAW; JURISDICTION; VENUE. This Agreement shall be
governed by and construed in accordance with the laws of the State of Delaware,
without regard to its principles of conflicts of law. The parties hereto

federal court located in the District of the State of Delaware in connection
with any action or proceeding arising out of or relating to this Agreement, any
document or instrument delivered pursuant to, in connection with or

right or remedy under this Agreement or any other agreement between Newco and
any Subscriber, or otherwise or delay by Newco in exercising such right or
remedy, will not operate as a waiver thereof.

         7.8   INVALIDITY. If any provision of this Agreement is invalid or
unenforceable under any applicable statute or rule of law, then such provision
shall be deemed inoperative to the extent that it may conflict therewith and
shall be deemed modified to conform with such statute or rule of law. Any
provision hereof that may prove invalid or unenforceable under any law shall not
affect the validity or enforceability of any other provision hereof.

         7.9   FURTHER ASSURANCE. The parties agree to execute and deliver all

         than the Investors, shall sell, transfer, assign, pledge or otherwise
         dispose (whether voluntarily or involuntarily, by operation of law or
         otherwise a "TRANSFER") of any interest in any Shares, whether now
         owned or hereafter acquired, without the prior written consent of the
         Investors, unless such Transfer is made in accordance with SECTION
         2(d), 3, 4, 6, or 7.

                  (b) RESTRICTIONS ON TRANSFER. From and after the Public
         Company Date, no Stockholder shall Transfer any interest in any Shares,
         whether now owned or hereafter acquired, without the consent of the
         Investors, except in compliance with SECTION 2(c), 2(d), 3, 4, 6, or 7.
         Each Stockholder agrees not to consummate any Transfer subject to this
         Agreement until 20 days after the later of the delivery to the other
         Stockholders of such Stockholder's Offer Notice or Sale Notice (if
         required by this Agreement), unless the parties to the Transfer have
         been finally determined pursuant to this SECTION 2 prior to the
         expiration of such 20 day period (the "ELECTION PERIOD").

                  (c) FIRST OFFER RIGHT. At least 20 days prior to making any
         Transfer of any Shares after the Public Company Date, other than a
         Transfer of Shares held by the Investors, the Stockholder intending to
         make such transfer (the "TRANSFERRING STOCKHOLDER") shall deliver a
         written notice (the "OFFER NOTICE") to the other Stockholders (the
         "OTHER STOCKHOLDERS"). The Offer Notice shall disclose in reasonable
         detail the proposed number of Shares to be transferred, the identity of
         the proposed transferee, and the proposed terms and conditions of the
         Transfer and shall be accompanied by a bona fide offer to purchase such
         Shares on such terms and conditions from an Independent Third Party or
         other Person not an Affiliate of the Transferring Stockholder. Each
         Other Stockholder may elect to purchase all (but not less than all) of
         its, his or her Pro Rata Share (as defined below) of the Shares
         specified in the Offer Notice at the price and on the terms specified
         therein by delivering written notice of such election to the
         Transferring Stockholder as soon as practical but in any event within
         10 days after delivery of the Offer Notice. Any Shares not elected to
         be purchased by the end of such 10 day period shall be reoffered for
         the 10 day period prior to the expiration of the Election Period by the
         Transferring Stockholder on a pro rata basis to the Other Stockholders
         who have elected to purchase their Pro Rata Share. If any Other
         Stockholders have elected to purchase Shares from the Transferring
         Stockholder, the transfer of such shares shall be consummated as soon
         as practical after the delivery of the election notices, but in any
         event within 10 days after the expiration of the Election Period. To
         the extent that the Other Stockholders have not elected to purchase all
         of the Shares being offered, the Transferring Stockholder may, within
         30 days after the expiration of the Election Period, transfer such
         Shares to the proposed transferee named in the Offer Notice for the
         price per Share specified in the Offer Notice and on the other terms
         and conditions stated in the Offer Notice. The purchase price specified
         in any Offer Notice shall be payable solely


                                       3
<PAGE>

         in cash at the closing of the transaction. Each Stockholder's "Pro Rata
         Share" shall be based upon such Stockholder's proportionate ownership
         of all Shares on a fully-diluted basis.

                  (d) PERMITTED TRANSFERS. The restrictions and rights contained
         in this SECTION 2 shall not apply with respect to any Transfer of
         Shares:

                      (i)   by a Leven Stockholder pursuant to applicable
                  laws of descent and distribution or among the Leven Family
                  Group; provided, however, that the restrictions contained in
                  this Agreement shall continue to be applicable to the Shares
                  after any such Transfer; and provided, further, that the
                  transferees of such Shares shall have agreed in writing to be
                  bound by the provisions of this Agreement affecting the Shares
                  so transferred;

                      (ii)  by a Leven Stockholder in a Brokers Transaction,
                  after notice to the Investors, at any time and from time to
                  time after the later of the Public Company Date and the second
                  anniversary of the Effective Date; provided that the Leven
                  Stockholders shall not be permitted to Transfer pursuant to
                  this SECTION 2(d)(II) and SECTION 6(a), in the aggregate, more
                  than one-third of their Original Shares before the third
                  anniversary of the Effective Date or more than two-thirds of
                  their Original Shares before the fourth anniversary of the
                  Effective Date;

                      (iii)  by any Leven Stockholder to an Investor; or

                      (iv)   by any Stockholder to the Company.

         3.       TAG-ALONG RIGHTS. In the event that the Investors propose to
Transfer, in one or a series of related transactions, more than 20% of their
aggregate Original Shares to one or more Independent Third Parties, they shall
deliver a written notice (the "SALE NOTICE") to the Other Stockholders,
specifying in reasonable detail the identity of the prospective transferee(s)
and the terms and conditions of the Transfer. The Other Stockholders may elect
to participate in the contemplated Transfer with respect to any Shares they then
hold by delivering written notice to the Investors within 10 days after delivery
of the Sale Notice. If any Other Stockholders have elected to participate in
such Transfer, the Investors and such Other Stockholders shall be entitled to
sell in the contemplated Transfer, at the same price and on the same terms, a
number of Shares equal to the product of (a) the quotient determined by dividing
the percentage of Shares owned by such person by the aggregate percentage of
Shares owned by Investors and the Other Stockholders participating in such sale
and (b) the number of Shares to be sold in the contemplated Transfer. The
Investors shall use their best efforts to obtain the agreement of the
prospective transferee(s) to the participation of the Other Stockholders in the
contemplated Transfer, and the Investors shall not transfer any of their Shares
to the prospective transferee(s) if the prospective transferee(s) declines to
allow the participation of the Other Stockholders.

         4.       CO-SALE RIGHTS. In the event that the Investors propose to
Transfer more than 50% of their Shares to one or more Independent Third Parties,
they may deliver a written


                                       4
<PAGE>

notice (the "CO-SALE NOTICE") to the Other Stockholders, not less than 10 days
prior to the date of such Transfer, specifying in reasonable detail the identity
of the prospective transferee(s) and the terms and conditions of the proposed
transfer and directing that the Stockholders shall participate in such proposed
Transfer. If the Investors give the Co-Sale Notice, each Stockholder shall
participate in such Transfer and sell, at the same price and on the same terms,
a number of Shares equal to the product of (a) the quotient determined by
dividing the number of Shares owned by each Stockholder by the aggregate number
of Shares owned by all Stockholders and (b) the number of Shares to be acquired
by the proposed transferee.

         5.       PLEDGE OF SHARES. From and after the Effective Date, no Shares
may be pledged without the prior written consent of the Investors which consent
may be withheld in their sole discretion.

         6.       PUT OPTIONS.

                  (a) OPTION. At any time and from time to time after the second

provided in this SECTION 6.

                  (c) EXERCISE OF OPTION. The options provided in Section 6(a)
and (b) shall be exercised by delivering written notice of exercise to the
Investors or their permitted transferees.

                  (d) PURCHASE PRICE; CLOSING. The purchase price of Shares

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
                  TERMS AND CONDITIONS OF A STOCKHOLDERS AGREEMENT DATED AS OF
                  _____________, 2000, AS THE SAME MAY BE AMENDED FROM TIME TO
                  TIME (THE "STOCKHOLDERS AGREEMENT'), BY AND AMONG VARIOUS
                  INDIVIDUAL SIGNATORIES THERETO AND THE COMPANY, A COPY OF
                  WHICH IS AVAILABLE AT THE PRINCIPAL OFFICE OF THE COMPANY. THE

<PAGE>

                  OR OTHER DISPOSITION OF SUCH SHARES BY THE HOLDER THEREOF IS
                  SUBJECT TO THE TERMS OF THE STOCKHOLDERS AGREEMENT, WHICH
                  PROVIDES, AMONG OTHER THINGS, THAT UNDER SPECIFIED
                  CIRCUMSTANCES THE COMPANY AND OTHER SPECIFIED PERSON HAVE THE
                  RIGHT TO PURCHASE SUCH SHARES FROM THE HOLDER THEREOF."

         The Company shall imprint such legend on certificates evidencing Shares
outstanding as of the Effective Date. The legend set forth above shall be
removed from the certificates evidencing any Shares that are no longer subject

any purpose.

         11.      AMENDMENT AND WAIVER. Except as otherwise provided herein, any
provision of this Agreement may be amended, modified, or waived if such
modification, amendment or waiver is approved in writing by the holders of at
least 90% of the Shares; provided that no such covenant shall materially and
adversely affect the right of any Stockholder who did not consent thereto. The
failure of any party to enforce any of the provisions of this Agreement shall in
no way be construed as a waiver of such provisions and shall not affect the
right of such party thereafter to enforce each and every provision of this
Agreement in accordance with its terms.

         12.      SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
