capital stock as described in EXHIBIT F, unless otherwise specifically provided:

          (a)  SELLERS' TITLE TO REF SHARES; CAPITAL STRUCTURE.  The Sellers are
the record and, except for the Alysha Ferguson Trust and the Courtney Ferguson
Trust, the beneficial owners and holders of the REF Shares, including, without
limitation, all voting power and investment power with respect to the REF
Shares, or the REF Shares are subject to Sellers control and direction and are
free and clear of all liens, security interests, pledges, restrictions,
encumbrances, equities, claims, charges, voting agreements, voting trusts,
proxies and rights of any kind, nature or


                                      -6-


description, whatsoever (collectively, "Encumbrances"); Sellers have full 
legal right and power and all authorizations and approvals required by law 
including all resolutions and consents of the directors of REF, to sell, 
transfer and deliver the REF Shares as contemplated hereunder, and to make 
the representations, warranties and agreements made hereunder, and upon 
consummation of the transactions contemplated herein, the Buyer shall receive 
good and marketable title to the REF Shares free and clear of all 
Encumbrances.  The REF Shares constitute all of the issued and outstanding 
capital stock of REF, and there are no options, warrants, convertible 
securities, debt securities or the like issued or outstanding or through 
which any party could acquire capital stock in REF.  All of the REF Shares 
have been duly authorized, validly issued, fully paid and are non-assessable. 
 None of the Shares have been issued in violation of the rights of any other 
person or entity.

          (b)  CORPORATE EXISTENCE AND POWER.  REF is a corporation duly
organized, validly existing and in good standing under the laws of the province
of Ontario, and is qualified or licensed to do business in good standing in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification or licensing necessary.
REF has all requisite corporate power and authority to own, lease or operate its
properties and assets, and to carry on its business as now being conducted or
operated.

          (c)  AUTHORIZATION.  This Agreement has been duly executed by Sellers,
and this Agreement and all agreements, instruments and certificates to be
delivered by Sellers pursuant to this Agreement (hereafter referred to as the
"Sellers' Purchase Documents") constitute the valid and legally binding
obligations of Sellers, enforceable against Sellers, jointly and severally, in
accordance with its terms.  Sellers have obtained all necessary authorizations,
consents and approvals, governmental and otherwise, required for the execution
and delivery of this Agreement and Sellers' Purchase Documents and performance
of Sellers' obligations hereunder and thereunder.

          (d)  NO RESTRICTIONS.  The execution, delivery and performance of the
Sellers' Purchase Documents by Sellers in accordance with their respective terms
will not, with or without the giving of notice or the passage of time, or both,
conflict with, result in a default, right to accelerate or material loss of
rights under, or result in the creation of any lien or encumbrance, or require
the consent of any third party or governmental authority, pursuant to (i) any
provision of the articles of incorporation or bylaws of REF as of the date
hereof, or (ii) any law, statute or regulation, judgment, order, writ,
injunction, or decree applicable to the Sellers or REF, or (iii) any franchise,
mortgage, loan agreement, indenture or deed of trust or any lease, license,
agreement, security agreement, security interest, or any law, rule, regulation,
order, judgment or decree to which Sellers or REF is a party or by which any of
them or any of the assets of REF may be bound, subject to or affected.

          (e)  BURDENSOME AGREEMENTS.  The Sellers and the REF Shares are not,
and neither REF nor its assets, properties or businesses are, subject to or
bound or affected by any charter, bylaw or other corporate or contractual
restriction or any order, judgment, decree, law, statute, ordinance, rule,
regulation or other restriction of any kind or character which would or could
(i) prevent Sellers from entering into the Sellers' Purchase Documents or from
consummating


                                      -7-


the transactions contemplated herein, or (ii) materially and adversely affect 
the REF Shares or REF's assets, properties, businesses, prospects or 
condition, financial or otherwise.

          (f)  NO SUBSIDIARIES.  REF does not own any interest, directly or
indirectly, in any other corporation, joint venture or entity, except that REF
owns all of the issued and outstanding capital stock of (i) the Softworks Group
Inc., a corporation organized under the laws of Ontario which was acquired in
1995 and is inactive, and (ii) Ref Retail Systems, Inc., a corporation organized
under the laws of the state of Delaware, which corporation has no assets or
liabilities and is inactive.  REF is not subject to any requirement or
obligation to provide funds to, or invest in, any other entity.

          (g)  FINANCIAL INFORMATION AND STATEMENTS.  All of the financial
information relating to REF's business (the "Financial Information") provided by
Sellers or REF in writing to Buyer prior to the date of this Agreement and the
Closing is true, correct and complete and is a fair and accurate presentation of
the results of the operations and the financial condition of REF for all periods
and dates indicated therein.  The Financial Statements of REF identified on
SCHEDULE 10(g) and heretofore provided by Sellers to Buyer (the "Financial
Statements") are true, correct and complete in all material respects and fairly
present the financial position of REF as of the dates and for the periods shown
on such financial statements.  No event has occurred since the date of the most
recent Financial Statements that would have a material adverse effect upon the
foregoing except that REF paid bonuses in the total amount of (CAN) $45,000 to
certain employees in April, 1996.  The Financial Statements do not contain any
untrue statement of any material fact and do not omit to state any material fact
necessary in order for the statements contained in this Agreement not
misleading.  Buyer is arranging for an audit of REF's financial statements at
Buyer's expense.

          (h)  ABSENCE OF UNDISCLOSED LIABILITIES.  The Financial Statements
make full and complete disclosure and provision for all material obligations,
liabilities or commitments (fixed and contingent) of REF.  Except as set forth
in SCHEDULE 10(h) or as reflected or reserved against in the Financial
Statements, as of March 31, 1996, REF had no liabilities or obligations, whether
accrued, absolute or contingent.  REF has no debt, liability or obligation to
Sellers as of the date hereof and the Closing, excepting only accrued and unpaid
payroll to make up to one payroll period in amounts consistent with the amounts
paid in the previous twelve months.

          (i)  TITLE TO ASSETS.  REF owns and has good and marketable title to
the all of the assets as set forth in the Financial Statements, including but
not limited to source code, object code, data base schema, product documentation
and user manuals for its point-of-sale products and its REF Open Enterprise
products, and none of REF's assets are subject to any security interest,
mortgage, pledge, lien or conditional sales agreement, encumbrance or any
material adverse claim of any nature whatsoever except as set forth in SCHEDULE
10(i) hereto.  Except as set forth on SCHEDULE 10(i), no material personal
property assets of REF reflected in the Financial Statements has been sold or
disposed of since the date of the Financial Statements.

          (j)  PAYMENT OF TAXES.  REF has filed all tax returns, reports and
related information (collectively, the "Returns") required to have been filed by
REF under any applicable law prior to the date hereof, and will have filed all
Returns required to have been filed by REF as of


                                      -8-


the Closing, and no waiver of the applicable statute of limitations or 
extension of the time for filing a Return or paying such tax is presently or 
will be as of the Closing in effect. The Returns filed contain no material 
misstatements or omissions, and all taxes referenced in such Returns have 
been paid.  REF has correctly characterized its respective employees and 
independent contractors for tax purposes.  Neither Sellers nor REF has any 
knowledge, whether actual or constructive, of any facts which would or could 
constitute grounds for the assessment of any additional taxes by any taxing 
authority.  In addition to the foregoing, Sellers shall be responsible for 
the payment of any tax or assessment that may be imposed on REF as a 
consequence of the restructuring of REF's capital stock as described in 
EXHIBIT F.

          (k)  CONDITION OF ASSETS; ACCOUNTS RECEIVABLE.  As of the date hereof,
all of the tangible assets of REF have been properly maintained in accordance
with normal and customary business practice and are in good working order and
condition, reasonable wear and tear excepted.  REF is not now nor has REF ever
been, the owner of real property.  The accounts receivable included on the
Financial Statements represent valid obligations, arose from bona fide
transactions, and to the knowledge of Sellers, are current and collectible.
Sellers believe that the reserve for bad debts shown on the Financial
Statements, if any, is adequate and consistent with generally accepted
accounting principles.

          (l)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since March 31, 1996, REF
has not:

           (i) incurred any material obligation or liability, absolute, accrued,
contingent or otherwise, whether due or to become due, except in a manner in the
ordinary course of business and consistent with prior practices, or incurred any
obligation to Sellers other than the payment of salary in accordance with prior
practices;

          (ii) sold, transferred, leased to others or otherwise disposed of any
material assets, except in a manner in the ordinary course of business and
consistent with prior practices;

          (iii) suffered any damage, destruction or loss (whether or not

reasonably be expected to have, a material adverse effect on REF's condition
(financial or otherwise), properties, assets, liabilities or operations;

          (iv) had any material change in its relations with its substantial
customers or suppliers; provided, however, any disclosures made by Sellers or
REF to Buyer regarding the proposed contract with the U.S. Postal Service shall
not constitute a material change;

          (v)  transferred or granted any rights under, or entered into any
settlement regarding the breach or infringement of, any license, trademark,
trade name, or similar right, or modified any existing rights with respect
thereto;

or in the aggregate, has had or is reasonably expected to have a material
adverse effect on REF's condition (financial or otherwise) or its business,
operations or assets;


                                      -9-

than in substantially the same manner in which it has theretofore been 
conducted;

          (viii)  increased the level of compensation payable to any officer

          (x)     made any increase in or commitment to adopt or increase any 
employee benefits or benefit plans;

          (xi)    except for customer purchase agreements, made or entered

          (xii)   issued, granted or sold, or agreed to issue, grant or sell, 
any capital stock of REF, or any convertible securities, debt securities, 
rights with respect to securities, or other securities of REF, except for the 
restructuring set forth on EXHIBIT F;

          (xiii)  declared any dividend or made any payment or distribution 
to the shareholders of REF, or purchased or redeemed any of its outstanding 
capital stock; or

          (xiv)   deferred the payment of any expense or liability, or 
prepaid any expense or liability, in anticipation of the consummation of the 
transactions contemplated in this Agreement.

          (m)  PERMITS AND LICENSES.  There are no permits, licenses or
franchises issuable by governmental agencies which are necessary in connection
with the business of REF or ownership of its assets, other than those listed on
the attached SCHEDULE 10(m) (the "Permits").  All of the Permits are, as of the
date hereof and the Closing, in full force and effect, no suspension or
cancellation has been threatened and no cause for such cancellation or
suspension exists, and, no consent of any issuer or grantor of a Permit is
required in connection with the execution and delivery of Sellers' Purchase
Documents or the consummation of the transactions contemplated herein which has
not been obtained by the Sellers as of the Closing.

          (n)  COMPLIANCE WITH LAWS.  The business and operations of REF have
been conducted in accordance and in compliance with all applicable laws,
ordinances, rules and regulations of all authorities.  Neither the Sellers nor
REF has received any notice of violation of any such laws, ordinances, rules or
regulations.

          (o)  TRADE NAME AND TRADEMARK.  REF owns its business trade name and

REF is infringing upon or otherwise acting adversely to any copyrights,
trademarks, service marks, trademark rights, trade names, patents, patent
rights, licenses or trade secrets allegedly owned by any person, firm,
corporation or other entity.


                                      -10-


          (p)  TRADE SECRETS AND CUSTOMER LIST.  REF has the right to use, free
and clear of any claims or rights of others, all trade secrets and customer

any confidential information or trade secrets of any third party in connection
with its business.

          (q)  SELLERS' INTEREST IN SIMILAR BUSINESSES.  Sellers do not have any
financial interest in any person, firm, corporation or other entity which is, or

which Sellers or REF is also a party.

          (r)  LITIGATION; LAWS.  Except as disclosed in Section 8(d) of this
Agreement, there is no claim, legal action, arbitration, governmental
investigation or other legal or administrative proceeding, nor any other decree
or judgment (collectively, "Litigation") in progress,  pending or in effect, or
threatened, against or relating to Sellers or REF, or REF's respective assets,
business or operations, or to the transactions contemplated by the Sellers'
Purchase Documents, and neither Sellers nor REF knows, or has any reason to
know, of any basis for the same.

          (s)  DISCLOSURE.  No representation or warranty by Sellers contained
in this Agreement, and no information heretofore provided to the Buyer, or
contained in the Financial Information or any other instrument or document
furnished to Buyer pursuant to this Agreement or in connection with the

fact or omits to state a material fact necessary in order to make the statements
contained therein not misleading.  The recitals to this Agreement shall be
deemed to be representations and warranties of the Sellers hereunder.

          (t)  LEASED REAL PROPERTY.

               (i)  SCHEDULE 10(t) attached hereto is a true, correct and
complete list of all real property leased, by REF and used in the conduct of
REF's business, and all subleases, consents, licenses and other agreements
(collectively, the "Real Property Leases") under which REF uses or occupies or
has the right to possess, enjoy, use or occupy, now or in the future, any real
property, building, structure or other improvement (the real property,
buildings, structures, and other improvements herein referenced being
collectively referred to as the "Real Property"), which list sets forth the date
of and parties to each Real Property Lease, the date of and parties to each
amendment, modification and supplement thereto, the rent, term and renewal terms
(whether or not exercised) of each Real Property Lease and a general description
of the Real Property.  REF has not assigned, subleased or otherwise encumbered
its interest in any of the Real Property.  Neither Sellers nor REF has received
any notice that they do not currently possess all certificates of occupancy,
permits, licenses and authorizations (collectively, the "Real Property Permits")
of all governmental authorities and from all insurance companies and fire rating
and other similar boards and organizations (collectively, "insurance
organizations"), required or appropriate to have been issued to enable the Real
Property to be lawfully leased, operated, occupied and used for all of the
purposes for which they are currently owned, leased, operated, occupied and
used.

          (ii) No notice of violation of laws, ordinances, regulations, orders,
zoning laws, building laws or fire laws or requirements covering the Real
Property (collectively, the "Real


                                      -11-


Property Laws") are outstanding with respect to the Real Property to the 
extent that any such violation has not been cured or any such notice not 
complied with, and neither Sellers nor REF has received or currently expect 
to receive any notice of violation or claimed violation of any Real Property 
Law.

          (iii)   Sellers and REF have not received notice and have no
knowledge of any pending, threatened or contemplated condemnation proceeding
affecting any of the Real Property or of any sale or other disposition of the
Real Property or any portion thereof if lieu of condemnation.

          (iv)    Sellers and REF are not and have never been in violation 
of, and no Seller has any notice or actual or constructive knowledge of any 
violation of, any applicable laws, statutes, rules, regulations, or 
ordinances relating to public health, safety, or the treatment, storage, use, 
release, disposal, sale, distribution, or management of hazardous substances, 
including, but not limited to, substances defined or listed as "hazardous 
substances", "hazardous materials", "hazardous waste", "extremely hazardous 
substances", "toxic substances", "toxic chemicals", or any variation thereof 
under applicable laws, or determined at any time to be such pursuant to 
applicable laws or rules or regulations adopted or publications promulgated 
pursuant to such laws (collectively, "Hazardous Substances").

          (u)  SELLERS' EMPLOYEES.  Except for confidentiality contracts listed
on SCHEDULE 10(u), REF does not have any employment or noncompetition agreements
with any of its directors, officers or employees and each of its employees is
employed "at will" and may be terminated at any time, with or without cause.
REF is not a party to any collective bargaining agreement and no proposals have
been made to negotiate or enter into any collective bargaining agreement in
connection with REF's business.  REF is in compliance with all applicable laws
respecting employment and employment practices, terms and conditions of
employment, and wages and hours, and is not engaged in any unfair labor
practices.  There is no unfair labor practice or  discrimination complaint
against REF pending before or threatened before the Ministry of Labour or any
other board, department, commission, or agency; nor does any basis therefor
exist; and there is no labor strike, dispute, grievance, controversy or other
labor trouble pending or threatened, affecting REF  nor does any basis therefor
exist.  REF has withheld all material amounts required by law or agreement to be
withheld from the wages or salaries of its employees prior to the date of this
Agreement and the Closing, and is not liable for any material arrears of wages
or any material taxes or penalties for failure to comply with any of the
foregoing.

          (v)  EMPLOYEE BENEFITS.  REF has no accrued obligations, whether
arising by operation of law, by contract or by past custom, for payments to
trusts or other funds or to any governmental agency, with respect to
unemployment compensation,  social security, pension or any other benefits for
its employees as of the date hereof and the Closing, except as disclosed on
SCHEDULE 10(v).  All reasonably anticipated obligations of REF (whether arising
by operation of law, by contract or by past custom) for salaries, vacation and
holiday pay, bonuses and other forms of compensation which were or as of the
date of this Agreement or the Closing are payable to REF's employees have been
included in the Financial Statements or have been paid.  Except as set forth on
SCHEDULE 10(v) hereto, REF does not maintain any pension, retirement,
disability, medical,


                                      -12-


dental, or other death benefit plan, profit sharing, deferred compensation, 
stock option, or severance plan.

          (w)  MATERIAL CONTRACTS.  Except as set forth on SCHEDULE 10(w) hereto

"Contracts"), REF is not party to or bound by any written or oral agreement
listed below relating to business:

           (i)    contract, commitment or arrangement for capital expenditures
having a remaining balance in excess of $1,000;

           (ii)   contract, commitment or arrangement containing covenants not

disclose any information relating to any person or entity;

           (iii)  loan, credit, promissory note, guarantee, or other evidence

assets, products, or services involving a value or more than $10,000.

Except as set forth in SCHEDULE 10(w), each Contract is terminable pursuant to
the terms thereof without penalty, cost or liability on notice not exceeding
thirty (30) days.  REF is not in material breach, and has not received notice
that it is in material breach, of any of the Contracts.  None of such Contracts
will be in default or breach as a result of the transactions contemplated in
this Agreement, and as of the Closing no consent of any party is required
thereunder in connection with the change in control contemplated in this
Agreement which has not been obtained by the Sellers.

          (x)  PREDOMINANT CUSTOMERS.  Except as set forth on SCHEDULE 10(x)
hereto, no single customer of REF accounted for over five percent (5%) of the
revenues of REF's business during the fiscal year immediately preceding the date
of this Agreement.  Since March 31, 1996, and except as set forth on SCHEDULE
10(x), no customer or vendor who has accounted for over five percent (5%) of the
revenues of REF's business during the fiscal year immediately preceding the date
of this Agreement indicated to Sellers or REF that it intends to cease doing
business with REF or materially alters the amount or pricing of business done
with REF.
 
          (y)  INSURANCE.  REF has insurance on its tangible real and personal
property and assets, whether owned or leased, against loss or damage by fire or
other casualty, in amounts equal to or in excess of the full replacement value
thereof, and comprehensive liability insurance with limits of liability of at
least $1,000,000.  All such insurance is in full force, with the premiums

which is a Seller, is not a non-resident of Canada within the meaning of the
Income Tax Act.

     11.  REPRESENTATIONS AND WARRANTIES OF THE BUYER.  As a material inducement
to the Sellers entering into this Agreement, the Buyer hereby represents and
warrants to the Sellers the following, in each case as of the date of this
Agreement and the Closing, unless otherwise specifically provided:

          (a)  AUTHORIZATION.  This Agreement has been duly executed by Buyer,
and this Agreement and all agreements, instruments and certificates to be
delivered by Buyer pursuant to this Agreement (hereafter referred to as the
"Buyer's Purchase Documents") constitute the valid and legally binding
obligation of Buyer, enforceable against Buyer in accordance with its terms.
Buyer has obtained all necessary authorizations, consents and approvals,
governmental and otherwise, required for the execution and delivery of this
Agreement and performance of Buyer's obligations hereunder.

          (b)  NO RESTRICTIONS.  The execution, delivery and performance of the
Buyer's Purchase Documents by Buyer in accordance with its terms will not, with
or without the giving of notice or the passage of time, or both, conflict with,
result in a default, right to accelerate or material loss of rights under, or
result in the creation of any lien or encumbrance, or require the consent of any
third party or governmental authority, pursuant to (i) any law, statute or
regulation, judgment, order, writ, injunction, or decree applicable to the
Buyer, or (ii) any franchise, mortgage, loan agreement, indenture or deed of
trust or any lease, license, agreement, security agreement, security interest,
or any law, rule, regulation, order, judgment or decree to which Buyer is a
party or by which Buyer or Buyer's assets may be bound, subject, or affected.

          (c)  BURDENSOME AGREEMENTS.  The Buyer is not, and Buyer's assets,
properties or businesses are not, subject to or bound or affected by any order,
judgment, decree, law, statute, ordinance, rule, regulation or other restriction
of any kind or character which would or could prevent Buyer from entering into
the Buyer's Purchase Documents or from consummating the transactions
contemplated herein.

          (d)  LITIGATION; LAWS.  There is no claim, legal action, arbitration,
governmental investigation or other legal or administrative proceeding, nor any
other decree or judgment in progress (collectively, "Litigation") pending or in
effect, or threatened, against or relating to the Buyer consummating the
transactions contemplated by the Buyer's Purchase Documents and Buyer does not
know, or have any reason to know, of any basis for the same.

     12.  COVENANTS OF SELLERS PRIOR TO CLOSING.  Until the Closing, the Sellers
shall, and shall take all action to cause REF to do or refrain from doing the
following, in each case unless otherwise agreed or approved in writing by the
Buyer, which agreement or approval may be given or withheld in Buyer's sole
discretion and without any resulting liability to the Buyer:

          (a)  Afford Buyer and his representatives with full and free access to
REF's personnel, properties, books, records, accounts, tax returns, contracts

may request.  The furnishing of such information to the Buyer and any such 
investigation by the Buyer shall not affect or in any way limit the Buyer's 
right to rely on the representations and warranties made by the Sellers in 
this Agreement, except to the extent that the information provided by Sellers 
prior to the Closing shows that a representation or warranty of the Sellers 
made in this Agreement is inaccurate, and the Buyer completes the 
transactions hereunder notwithstanding such inaccuracy.

          (b)  Except as permitted or required under this Agreement, operate the
business and operations of REF only in the ordinary course of business as
conducted prior to March 31, 1996, not take any action or course of action and
not permit by inaction, any circumstance or event which would or could cause the
Sellers to be in breach or default of Sellers' obligations, covenants,
agreements, representations, warranties or restrictions contained in this
Agreement, and use their best efforts to (i) preserve and keep intact the
present business organizations of REF; (ii) keep available the services of REF's
present officers and employees; (iii) preserve the relationships with the
customers, suppliers, and others having business dealings with REF; (iv)

known at the date hereof, would have been required to be set forth or 
disclosed in or pursuant to this Agreement, or which would or could result in 
the breach by Sellers of any representation or warranty or a breach of any 
covenant or agreement hereunder.

          (e)  Not undertake any course of action inconsistent with the
satisfaction of the conditions to Closing set forth herein, and do all such acts
and take all such measures as may be necessary to comply, and be in compliance,
with the representations, warranties, covenants and agreements contained in this

          (f)  Not make any change to the Articles, bylaws or capital

stock or security of REF, or declare or pay any dividend or distribution out 
of REF or incur any material obligation by REF, or modify, terminate or enter 
into any commitment or Contract of either REF,  except for the restructuring 
contemplated by EXHIBIT F.


                                      -15-


          (g)  Consult with and obtain the approval of the Buyer as to and on
any and all material business decisions or proposals involving REF.

The parties acknowledge and agree that the provisions of this Section 12 are
intended and shall be interpreted and construed to give the Buyer an absolute
veto power over any proposed action or decision, whether corporate, business, or
otherwise, of Sellers or REF which action or decision, more likely than not,
could have a material adverse effect on the business, operations, assets, or
liabilities of REF or the purchase of all of the  REF Shares as contemplated in
this Agreement.  The Sellers hereby represent and warrant that they, jointly and
severally, have the power and authority to perform each of their obligations and
commitments under this Section 12.

     13.  COVENANTS OF BUYER PRIOR TO CLOSING.  Until the Closing, the Buyer

Buyer or its affiliates) to cause a secondary public offering pursuant to a
letter of intent from R.J. Steichen & Company attached hereto as EXHIBIT G to
raise at least $6,500,000 net proceeds to Buyer.  The secondary offering is
anticipated to be completed on or before October 21, 1996.  The Closing is
intended to be simultaneous with the closing of the secondary offering.  The
proceeds of the secondary offering will be used to pay the Purchase Price.  If
the secondary offering is not completed on or before October 21, 1996, the Buyer
may seek other financing including a private placement to meet its obligations
to the Sellers.  Notwithstanding anything contained in this Agreement to the
contrary, the Buyer's obligations hereunder shall terminate upon the lawful
termination of this Agreement.

     16.  TERMINATION.  This Agreement may be terminated at any time prior to
the Closing:

          (a)  By either the Buyer or the Sellers if, without fault of the
terminating party, the Closing shall not have been consummated on or before
October 21, 1996, or such later date as may be established as set forth in
Section 5 of this Agreement;

          (b)  By the mutual agreement of the parties;

          (c)  In the event of termination pursuant to Section 16(a) above,
written notice shall be given by the party terminating the Agreement and this
Agreement shall be terminated without further action.

          (d)  If this Agreement is terminated by the Buyer by reason (i) of any
representation or warranty of the Sellers made in this Agreement being untrue as
of the date hereof or thereafter (other than as a result of events not within
Sellers' reasonable control) becoming untrue, or (ii) the Sellers' breach of any
of their covenants or agreements contained in this Agreement, in either case, in
any respect that is materially adverse in relation to the transactions
contemplated hereby or the business of REF, then Sellers shall pay to the Buyer
all costs and expenses incurred by the Buyer in connection with the transactions
contemplated hereby, including, but not limited to attorneys fees and expenses
to a maximum of $50,000 without deduction or set-off of any kind, costs and fees
associated with the secondary offering and excluding the termination or "break
up" fees set forth in Section 16(f) of this Agreement.

          (e)  If this Agreement is terminated by the Sellers by reason (i) of
any representation or warranty of the Buyer made in this Agreement being untrue
as of the date hereof or thereafter (other than as a result of events not within
Buyer's reasonable control) becoming untrue, or (ii) the Buyer's breach of any
of its covenants or agreements contained in this Agreement, in either case, in
any respect that is materially adverse in relation to the transactions
contemplated hereby or the business of Buyer, then Buyer shall pay to the
Sellers all costs and expenses incurred by the Sellers in connection with the
transactions contemplated hereby,


                                      -18-


including, but not limited to attorneys fees and expenses to a maximum of 
$50,000 without deduction or set-off of any kind, and excluding the 
termination or "break up" fees set forth in SECTION 16(g) of this Agreement.

          (f)  If this Agreement or the transactions contemplated hereby are
terminated or abandoned by the Sellers and prior to or contemporaneously with
such termination or abandonment, (1) any corporation, partnership, person, other
entity or group, other than the Buyer shall have acquired or beneficially owns a
majority of the capital stock of REF, including the REF Shares, or shall have
been granted any option or right, conditional or otherwise, to acquire at least
a majority of the capital stock of REF, including the REF Shares, or (2) any
person shall have communicated to REF a proposal, which is approved by the
Sellers, (i) to acquire REF by merger, purchase of assets or otherwise, or (ii)
to make any offer to acquire the REF Shares, then Sellers shall promptly (and in
any event within ten days of receipt by the Sellers of written notice from the
Buyer that Buyer intends to seek liquidated damages rather than specific
performance of the Agreement) pay the Buyer, as a termination fee and liquidated
damages the sum of $250,000 and the Buyer agrees that in such event, Sellers
shall not be liable to the Buyer for any breach of this Agreement.  Sellers
agree that Buyer shall not be obligated to seek liquidated damages and may, at
Buyer's option, seek specific performance.

          (g)  If this Agreement or the transactions contemplated hereby are
terminated or abandoned by the Buyer, then Buyer shall promptly (and in any
event within ten days of receipt by the Buyer of written notice from the Sellers
that Sellers intend to seek liquidated damages) pay the Sellers, as a
termination fee and liquidated damages the sum of $250,000 and the Sellers agree
that in such event, Buyer shall not be liable to the Sellers for any breach of
this Agreement.

If this Agreement is terminated as provided herein, the obligations set forth in
Sections 16 and 19 shall survive any such termination.

     17.  INDEMNIFICATION AND SET-OFF.  Sellers hereby covenant and agree with
the Buyer that Sellers shall pay and perform, and shall indemnify, defend and
hold harmless the Buyer, the Buyer's affiliates, successors and assigns, from,
against and in respect of, any and all costs, losses, claims, liabilities,
fines, penalties, damages and expenses (including interest which may be imposed
in connection therewith and court costs and reasonable fees and disbursements of
counsel) (collectively, the "Sellers' Indemnified Liabilities") resulting from,
arising out of or incurred by any of them in connection with (i) any breach of
the representations or warranties made by the Sellers in this Agreement, or (ii)
the failure, breach or default by the Sellers in respect of any of the covenants
or agreements made by the Sellers in this Agreement or any document related
hereto.
 
          (a)  No claim whatsoever may be made by the Buyer as against the
Sellers, or any of them, in respect of alleged breaches of such representations
and warranties after the date which is twelve (12) months after the Closing
Date.  "Claim" shall mean the actual commencement of court or, in the
alternative, arbitration procedures by the Buyer respecting all such matters in
dispute.


                                      -19-


          (b)  The Buyer shall not be entitled to make any such claim if (i) the
Buyer has been advised in writing prior to the date of closing of the
inaccuracy, non-performance, non-fulfillment or breach which is the basis for
such claim  or (ii) information provided by Sellers prior to the Closing shows
that a representation or warranty of the Sellers made in this Agreement is
inaccurate, and, in either case, the Buyer completes the transactions, hereunder
notwithstanding such inaccuracy, non-performance, non-fulfillment or breach.

          (c)  The amount of any damages which may be claimed by the Buyer
pursuant to a claim shall be reduced by any insurance proceeds received by the
Buyer in relation to the matter which is the subject of the claim.

          (d)  The Buyer shall not be entitled to make any claim until the net
aggregate amount of all damages, losses, liabilities and expenses incurred by

contained in this agreement or contained in any document or certificate given in
order to carry out the transactions contemplated hereby, after taking into
account paragraph (d) of this Section 17, is equal to $10,000.  After the
aggregate amount of such damages, losses, liabilities and expenses incurred by
the Buyer exceeds $10,000, the Buyer shall be entitled to make claim for the
entire aggregate amount of damages after taking into account the provisions of
paragraph (d) of this section.

          (e)  Notwithstanding any other provisions of this Agreement, the
maximum aggregate liability of each of the Sellers in respect of all such claims
by the Buyer will be limited to the consideration received by each such Seller
pursuant to this Agreement.

     18.  REMEDIES.  Any dispute arising from the terms and conditions of this
Agreement shall be subject to final and binding arbitration by a single
arbitrator in Minneapolis, Minnesota under the rules of the Inter-American

deemed to be a waiver of any other.  Time is of the essence in this Agreement.
The prevailing party in any arbitration proceeding under this Agreement shall be
entitled to recovery of costs and reasonable attorneys' fees, in addition to
other relief.  The parties hereby submit to the personal jurisdiction of the
state or federal courts located in Minnesota for the enforcement of any
arbitration award.

     19.  EXPENSES.  Other than as expressly provided in Section 16 whether or
not the Closing shall occur, each of the Buyer and the Sellers shall pay their
own respective costs and expenses, including all fees and expenses of their
counsel, accountants and other representatives engaged or incurred in connection
with this Agreement and the transactions contemplated herein.  If the Closing
shall take place, a maximum of $50,000 of such costs and expenses of the Sellers
shall may be paid by or with funds from REF.  The costs and expenses of Anderson
