accurate and complete in all material respects) and fairly presents the
Seller's financial condition, assets and liabilities as of their respective
dates and the results of operations and cash flows for the periods related
thereto in accordance with GAAP, except that the 1998 unaudited Financial
Statements lack the footnote disclosure and normal recurring accruals otherwise
required by GAAP, none of which, if provided, would reflect a material adverse
change in the operations or financial condition of the Seller.

charges or penalties, interest or fines thereon or in respect thereof, except
(a) to the extent specifically reflected and accrued for or reserved against in
the Financial Statements, or (b) for liabilities specifically delineated on
Schedule 3.9.  Without limiting the foregoing, all obligations to be fulfilled

         adjustment referenced below.  All such Accounts Receivable are valid
         and have arisen in the ordinary course of business and, to Seller's
         knowledge, are not subject to any counterclaim or set-off. Schedule
         3.10-B shall be subject to a post-Closing audit and update to the
         reasonable satisfaction of Dwyer Group and Buyer in accordance with
         the terms of Section 5.5, to ensure such Schedule accurately reflects

<PAGE>   14

         post-Closing adjustment referenced below.  The Seller's Accounts
         Payable have arisen in bona-fide arm's length transactions in the
         ordinary course of the Seller's business consistent with past
         practice. Schedule 3.10-C shall be subject to a post-Closing audit and
         update to the reasonable satisfaction of Dwyer Group and Buyer in
         accordance with the terms of Section 5.5, to ensure such Schedule
         accurately reflects all Accounts Payable as of the Closing Date, it
         being understood that the total Accounts Payable set forth in Schedule
         3.10-C after the post- Closing audit shall not be more than one

furnished to Buyer.  Except as set forth on Schedule 3.12, the Seller is not in
default, and no event has occurred that is known or should be known to Seller
or Owner, which with the giving of notice or the passage of time or both would
constitute a default by the Seller, under any Material Contracts, and, no event
has occurred which with the giving of notice or the passage of time or both
would constitute such a default by any party to any such Material Contract.

         3.13    Real Property.  The Seller does not own any real property and
therefore is not required to possess any permits, licenses or certificates or
file any notices related to owning or leasing any real property.  The Seller

the leases described in Schedule 3.13, (collectively, the "LEASED REAL

Statements.

hearing or investigation against or involving the Seller or the Business under
any Environmental and Safety Requirement based on any such fact, event or
circumstance, including, without limitation, liability for cleanup costs,

         6.1     Owner's Knowledge.  Owner agrees and acknowledges that in
order to assure that the Business will retain its value as a "going concern,"
it is necessary that Owner undertake not to utilize his present special
knowledge of the Seller's Business to compete with the Buyer or any of the

possesses extensive knowledge and a unique understanding of the Business as
well as (subsequent to the transactions contemplated by this Agreement) the
proprietary and confidential information concerning Buyer and the Business; (c)
the agreements and covenants contained in this SECTION 6.1 are essential to

condition precedent to Buyer's willingness to purchase and pay for the

Affiliate; (d) Buyer would be irreparably damaged if Owner were to provide
services or any products to any person or entity in violation of the provisions
of this Agreement; (e) Owner has a means to support himself and his dependents

<PAGE>   24
Business without Buyer's or its Affiliates approval and the provisions of this
SECTION 6.1 will not impair such ability.

         6.2     Non-Compete.  Owner hereby agrees that for the five (5) year
period beginning on the Closing Date (the "RESTRICTED PERIOD"), he shall not
engage in or own any interest in any business, including any existing
Affiliate, that engages in or owns, invests in, operates, manages or controls
any venture or enterprise that directly or indirectly engages or proposes to
engage in the Business or any business competitive with the Seller or Buyer
within the United States, including its territories and possessions (the
"TERRITORY"), except pursuant to a Franchise Agreement with the Buyer or other
Affiliate of the Dwyer Group.

         6.3     Non-Solicitation.  Without limiting the generality of the
provisions of SECTION 6.2, Owner hereby agrees that, during the Restricted
Period, he will not and he will not permit any of his Affiliates to directly or
indirectly, solicit, or participate as employee, agent, consultant,
stockholder, director, partner or in any other individual or representative
capacity, in any business which solicits business from any person, firm,
corporation or other entity which was a customer of the Seller or its
Franchisees or Affiliates (existing or future) or licensees during the two (2)
year period preceding the Closing Date of this Agreement and/or during the
Restricted Period, or from any successor in interest to any such person, firm,
corporation or other entity for the purpose of securing business or contracts
related to the Business, except pursuant to a Franchise Agreement.

         6.4     Interference with Relationships.  During the Restricted
Period, Owner shall not and shall not permit any Affiliate to, directly or
indirectly, as an employee, agent, consultant, stockholder, director, co-
partner or in any other individual or representative capacity:  (i) without the
prior written consent of Buyer or Dwyer Group, employ or engage, recruit or
solicit for employment or engagement, any person who currently is or was
employed by the Seller or its Affiliate, or otherwise seek to influence or
alter any such person's relationship with Buyer or the Dwyer Group, except for
any former employee who is terminated by Buyer or an Affiliate of Buyer at
least six months prior to the commencement of such employment with any Seller
Party or (ii) solicit or encourage any present or future customer, supplier or
Franchisee or licensee of the Seller or Buyer to terminate or otherwise alter
his, her or its relationship with the Buyer or its Affiliates.

         6.5     Confidential Information.  During the Restricted Period and
thereafter, Owner shall and shall cause its Affiliate to, keep secret and
retain in strictest confidence, and shall not, without the prior written
consent of Buyer, furnish, make available or disclose to any third party or use
for the benefit of himself or any third party, any Confidential Information.
As used in this Agreement, "CONFIDENTIAL INFORMATION" shall mean any
information relating to the business or affairs of, Buyer, the Seller,
Franchisees or the Business, including but not limited to information relating
to financial statements, customer identities, potential customers, employees,
franchisees, suppliers, servicing methods, equipment, programs, strategies and
information, analyses, profit margins, or other proprietary information used by
Buyer and/or the Seller in connection with the Business; provided, however,
that Confidential Information shall not include any information which is in the
public domain or becomes known in the industry through no wrongful act on the
part of a Seller Party.  Each of the Seller Parties hereby acknowledges that
the Confidential Information is vital, sensitive, confidential and proprietary
to Buyer.

         6.6     Property of the Seller/Business.  All manuals, memoranda,
notes, lists, records and other documentation or papers (and all copies
thereof), including such items stored in computer memories, or microfiche or by
any other means, which will become Buyer's property (after the consummation of
transactions contemplated by this Agreement), are and shall be Buyer's property
and shall be delivered to Buyer promptly on the request of Buyer.  Owner
acknowledges that any such items are and have been a "work for hire" and any
copyrights in any of the forgoing were property of the Seller and upon
consummation of this transaction will be the property of Buyer.

         6.7     Blue-Pencil.  If any court of competent jurisdiction shall at
any time deem the term of this Agreement or any particular restrictive covenant
contained in this ARTICLE 6.1 too lengthy or the Territory too extensive, the
other provisions of this ARTICLE 6.1 shall nevertheless stand, the Restricted
Period herein shall be deemed to be the longest period permissible by law under
the circumstances and the Territory herein shall be deemed to comprise the
largest territory permissible by law under the circumstances.  The court in
each case shall reduce the time period and/or Territory to permissible duration
or size.

         6.8     Remedies.  Owner acknowledges and agrees that the covenants
set forth in this ARTICLE 6.1 are reasonable and necessary for the protection
of Buyer's business interests, that irreparable injury will result to Buyer if
any Seller Party breaches any of the terms of said restrictive covenants, and
that in the event of actual or threatened breach of any such restrictive
covenants, Buyer will have no adequate remedy at law.  Each Seller Party
accordingly agrees that in the event of any actual or threatened breach by
either of them or any Affiliate of any of the covenants set forth in this
ARTICLE 6, Buyer and Dwyer Group shall be entitled to immediate temporary
injunctive and other equitable relief, including suspension of payments under
the Term Note, without bond and without the necessity of showing actual
monetary damages, subject to hearing as soon thereafter as possible.  Nothing
contained herein shall be construed as prohibiting Buyer and Dwyer Group from
pursuing any other remedies available to it for such breach or threatened
breach, including the recovery of any damages which it is able to prove.

         claim (whenever made) by any third party (including governmental

         successful, would give rise to, demonstrate or evidence the existence
         of or relate to a misrepresentation or breach of any of the
         representations, warranties or covenants of the any of the Seller
         Parties;

                 (d)      any action, demand, proceeding, investigation or claim
         (whenever made) by any third party against or affecting Buyer (with
         respect to the Business or the  Purchased Assets) or the Purchased
         Assets relating to any personal injury or property damage caused, or
         alleged to be caused, by any goods sold, delivered or serviced by any
         Seller Party prior to the Closing Date;

                 (e)      any and all claims or other demands of any nature 
         asserted against Purchaser arising out of the failure of the parties
         to comply with any applicable UCC bulk transfer law and any costs
         incurred by Dwyer Group, Buyer or the Affiliates of either, with
         respect to such claims and demands.

                 (f)      any claim or assertion against the Buyer as to the
         Excluded Liabilities; or

                 (g)      any claim for payment of fees and/or expenses as a
         broker or finder in connection with the origin, negotiation, execution
         or consummation of this Agreement based upon any alleged agreement
         between the claimant and the Owner, or the Seller.

                 7.1.2    Indemnification by Buyer.  From and after the
Closing, Buyer and Dwyer Group, jointly and severally, agree to indemnify,
defend and save Owner, Seller and their respective Affiliates, and their
respective officers, directors, employees, trustees and agents (each, a "SELLER
INDEMNIFIED PARTY") forever harmless from and against, and to promptly pay to a
Seller Indemnified Party or reimburse a Seller Indemnified Party for, any and
all Losses actually sustained or incurred by any Seller Indemnified Party
relating to, resulting from, arising out of or otherwise by virtue of any of
the following:

                 (a)      any misrepresentation or breach of a representation
         or warranty made herein or in the Transaction Documents by Buyer or
         Dwyer Group, or non-compliance with or breach




                                       18
<PAGE>   27

         by Buyer or Dwyer Group of any of the covenants or agreements
         contained in this Agreement or the Transaction Documents to be
         performed by Buyer or Dwyer Group;

                 (b)      any action, demand, proceeding, investigation or
         claim (whenever made) by any third party (including governmental
         agencies) against or affecting Seller or its Affiliates which, if
         successful, would give rise to or evidence the existence of or relate
         to a misrepresentation or breach of any of the representations,
         warranties or covenants of Buyer or Dwyer Group;

                 (c)      any claim for payment of fees and/or expenses from a
         broker or finder in connection with the origin, negotiation, execution
         or consummation of this Agreement based upon any alleged agreement
         between the claimant and Buyer; or

                 (d)      any and all claims, liabilities, losses, damages,
         costs and expenses (including attorneys' fees and court costs), which
         any Seller Indemnified Party may incur arising out of Buyer's failure
         to timely pay, perform, discharge or otherwise satisfy all liabilities
         and obligations included in the Assumed Liabilities, referred to in
         Section 1.3 and identified in Schedule 1.3.

                 7.1.3    Indemnification Procedure for Third Party Claims.  In
the event that subsequent to the Closing any person or entity entitled to
indemnification under this Agreement (an "INDEMNIFIED PARTY") asserts a claim
for indemnification or receives notice of the assertion of any claim or of the
commencement of any action or proceeding by any entity that is not a party to
this Agreement or an Affiliate of a party to this Agreement (including, but not
limited to any domestic or foreign court or governmental authority, federal,
state or local) (a "THIRD PARTY CLAIM") against such Indemnified Party, against
which a party to this Agreement is required to provide indemnification under
this Agreement (an "INDEMNIFYING PARTY"), the Indemnified Party shall give
written notice together with a statement of any available information regarding
such claim to the Indemnifying Party within sixty (60) days after learning of
such claim (or within such shorter time as may be necessary to give the
Indemnifying Party a reasonable opportunity to respond to such claim).  The
Indemnifying Party shall have the right, upon written notice to the Indemnified
Party (the "DEFENSE NOTICE") within thirty (30) days after receipt from the
Indemnified Party of notice of such claim, which notice by the Indemnifying
Party shall specify the counsel it will appoint to defend such claim ("DEFENSE
COUNSEL"), to conduct at its expense the defense against such claim in its own
name, or if necessary in the name of the Indemnified Party; provided, however,
that the Indemnified Party shall have the right to approve the Defense Counsel,
which approval shall not be unreasonably withheld, and in the event the
Indemnifying Party and the Indemnified Party cannot agree upon such counsel
within ten days after the Defense Notice is provided, then the Indemnifying
Party shall propose an alternate Defense Counsel, which shall be subject again
to the Indemnified Party's approval. If the parties still fail to agree on
Defense Counsel, then, at such time, each of the Indemnifying and Indemnified
Parties shall choose an arbitrator who, in turn shall select a third
arbitrator, and the three arbitrators shall select Defense Counsel.

                 (a)      In the event that the Indemnifying Party shall fail
         to give the Defense Notice, it shall be deemed to have elected not to
         conduct the defense of the subject claim, and in such event the
         Indemnified Party shall have the right to conduct such defense in good
         faith and to compromise and settle the claim without prior consent of
         the Indemnifying Party and the



                                       19
<PAGE>   28

         Indemnifying Party will be liable for all costs, expenses, settlement
         amounts or other Losses reasonably paid or incurred in connection
         therewith.

                 (b)      In the event that the Indemnifying Party does deliver
         a Defense Notice and thereby elects to conduct the defense of the
         subject claim, the Indemnified Party will cooperate with and make
         available to the Indemnifying Party such assistance and materials as
         it may reasonably request, all at the expense of the Indemnifying
         Party, and the Indemnified Party shall have the right at its expense
         to participate in the defense assisted by counsel of its own choosing,
         provided that the Indemnified Party shall have the right to compromise
         and settle the claim only with the prior written consent of the
         Indemnifying Party, which consent shall not be unreasonably withheld
         or delayed.

                 (c)      Without the prior written consent of the Indemnified
         Party, the Indemnifying Party will not enter into any settlement of
         any Third Party Claim or cease to defend against such claim, if
         pursuant to or as a result of such settlement or cessation, (i)
         injunctive or other equitable relief would be imposed against the
         Indemnified Party, or (ii) such settlement or cessation would lead to
         liability or create any financial or other obligation on the part of
         the Indemnified Party for which the Indemnified Party is not entitled
         to indemnification hereunder.

                 (d)      The Indemnifying Party shall not be entitled to
         control, and the Indemnified Party shall be entitled to have sole
         control over, the defense or settlement of any claim to the extent
         that claim seeks an order, injunction or other equitable relief
         against the Indemnified Party which, if successful, could materially
         interfere with the business, operations, assets, condition (financial
         or otherwise) or prospects of the Indemnified Party (and the
         reasonable cost of such defense shall constitute an amount for which
         the Indemnified Party is entitled to indemnification hereunder).

                 (e)      If a decision is made to settle a Third Party Claim,
         which offer the Indemnifying Party is permitted to settle under this
         SECTION 7.1.3, and the Indemnifying Party desires to accept and agree
         to such offer, the Indemnifying Party will give written notice to the
         Indemnified Party to that effect.  If the Indemnified Party fails to
         consent to such firm offer within fifteen (15) calendar days after its
         receipt of such notice, the Indemnified Party may continue to contest
         or defend such Third Party Claim and, in such event, the maximum
         liability of the Indemnifying Party as to such Third Party Claim will
         not exceed the amount of such settlement offer, plus costs and
         expenses paid or incurred by the Indemnified Party through the end of
         such fifteen (15)-day period.

                 (f)      Any judgment entered or settlement agreed upon in the
         manner provided herein shall be binding upon the Indemnifying Party,
         and shall conclusively be deemed to be an obligation with respect to
         which the Indemnified Party is entitled to prompt indemnification
         hereunder.

                 7.1.4    Failure to Give Timely Notice.  A failure by an
Indemnified Party to give timely, complete or accurate notice as provided in
SECTION 7.1.3 will not affect the rights or obligations of any party hereunder
except and only to the extent that, as a result of such failure, any party
entitled to receive such notice was deprived of its right to recover any
payment under its applicable insurance




                                       20
<PAGE>   29

coverage or was otherwise directly and materially damaged as a result of such
failure to give timely notice.

                 7.1.5    Survival of Representations, Warranties and
Covenants; Limits on Indemnification Obligations.  Notwithstanding any right of
Dwyer Group to fully investigate the affairs of Seller, Owner and the Business,
and notwithstanding any knowledge of facts determined or determinable by Dwyer
Group pursuant to such investigation or right of investigation, Dwyer Group has
the right to rely fully upon the representations, warranties, covenants and
agreements of the Seller Parties contained in this Agreement or in any
certificate delivered pursuant to any of the foregoing.  All such
representations, warranties, covenants and agreements shall survive the
execution and delivery of this Agreement for a period of three years from the
Closing Date.  The maximum liability of Seller to indemnify the Buyer
Indemnified Parties pursuant to this SECTION 7.1 and the maximum liability of
Buyer to indemnify Seller Indemnified Parties pursuant to this SECTION 7.1
shall, in each case, be limited to an aggregate amount equal to the Purchase
Price plus the "purchase price" defined in and paid pursuant to the Stock
Purchase Agreement (this sum is referred to herein as the "AGGREGATE PURCHASE
PRICE"); provided, however, that the total aggregate indemnification liability
for either the Buyer or Seller under both this Agreement and the Stock Purchase
Agreement shall not exceed the Aggregate Purchase Price.  An Indemnified Party
shall be entitled to seek indemnification pursuant to this SECTION 7.1:  (i) on
December 31 and June 30 of each year; and (ii) when the aggregate amount of all
such Losses claimed directly and pursuant to Third Party Claims under this
Agreement and the Asset Purchase Agreement exceeds an amount equal to Twenty-
Five Thousand Dollars (U.S.$25,000), at either of which points the Indemnifying
Party shall be liable to the Indemnified Parties for the entire amount of all
such Losses claimed as of that time.

         7.2     Tax Returns.  Seller shall timely file and Owner shall cause
Seller to timely file all federal state and local Tax Returns of the Seller and
have paid or will pay all Taxes owed by or with respect to the Seller.  After
the Closing, Dwyer Group and Buyer on the one hand and Seller and Owner on the
other hand, will make available to the other as reasonably requested, all
information, records or documents relating to the liability for Taxes of Seller
for all periods prior to or including the Closing Date and will preserve such
information records or documents until the expiration of any applicable statue
of limitations or extensions thereof.

         7.3     Guaranty of Royalties.  Owner guarantees that royalties paid
by SEL, Inc. or any Affiliate successors or assigns operating a Franchised
Business in the Atlanta area, to Buyer shall be One Hundred Eighty Six Thousand
Dollars (U.S.$186,000) for the two (2) year period following Closing. In the
event that such royalties are less than Ninety Three Thousand Dollars
(U.S.$93,000) in the first or second year following Closing (after adjusting
for any credit in the second year, as described below), Dwyer Group shall
deduct the difference between Ninety Three Thousand Dollars (U.S.$93,000) and
the amount paid to Buyer from the next installment(s) due on the Term Note
payable under the Stock Purchase Agreement. In the event that such royalties
are greater than Ninety Three Thousand Dollars (U.S.$93,000) in the first year
following Closing, such overage shall be credited towards the royalties
collected in the second year following Closing.

         7.4     Setoff.  In addition to and not as a limitation of any of the
other remedies available to Buyer and Dwyer Group hereunder, Dwyer Group shall
be entitled to offset against the principal amount remaining on the Term Note
under the Stock Purchase Agreement any indemnifiable



                                       21
<PAGE>   30
Losses, which are liquidated in amount and as to which there is no reasonable
dispute, including Excluded Liabilities or otherwise.  In the event of such a
setoff, the quarterly payments of principal and interest shall be recalculated
based upon the new principal balance remaining after necessary deductions.

regarding the transactions contemplated by this Agreement shall be made jointly

         8.3     Severability.  The unenforceability or invalidity of any

provision of this Agreement may be waived, provided that any such amendment or
waiver will be binding on Buyer only if such amendment or waiver is set forth
in a writing executed by Buyer, and provided that any such amendment or waiver
will be binding upon Seller only if such amendment or waiver is set forth in a

hereto and delivered to the other.

         8.7     Expenses.  Except as paid prior to the date hereof or

         8.9     Headings.  The subject headings of Articles and Sections of
this Agreement are included for purposes of convenience only and shall not
affect the construction or interpretation of any of its provisions.

         8.10    Assignment.  This Agreement is intended to bind and inure to
the benefit of and be enforceable by the parties hereto and their respective
successors and permitted assigns.  This Agreement will not be assignable or

assign its



                                       23
<PAGE>   32
rights or delegate its responsibilities, liabilities, and obligations under
this Agreement to any person at any time without the consent of the other
parties, except that Buyer shall not be released from any payment obligation
and shall remain liable to Seller for any such payment obligation to the same
extent as any assignee.

         8.11    Definitions.  For purposes of this Agreement, the following
terms have the meaning set forth below:

                 "AFFILIATE" means an affiliate as defined in Rule 405 under
