ITEM 1.  CHANGES IN CONTROL OF REGISTRANT

         In connection with the Company's merger with Southern Resources, Inc.
         ("SRI"), discussed in Item 2 below, the Company issued 4,500,000
         shares of its common stock to four former shareholders of SRI, each
         active in the management and operations of SRI, in exchange for all of
         the outstanding stock of SRI.

         The shares issued represent approximately 27% of the total 16,681,270
         outstanding shares of the Company's common stock at the conclusion of
         the merger transaction. Although this represents less than majority
         ownership in the Company, it is management's belief that the
         individuals acting together could exercise significant influence in
         control matters. As a consequence, a material change in control of the
         Company may result from this transaction.

         The four persons who received stock in exchange for the shares of SRI
         and the number of shares received are as follows:

         The above named persons have the right to nominate one individuals for
         election to the board of directors of the Company.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On December 8, 1997, a subsidiary of Ringer Corporation (the
         "Company") merged with Southern Resources, Inc.  ("SRI"') which, on
         that date, became a wholly-owned subsidiary of the Company. Prior to
         the merger, SRI was privately-held. SRI is a Fort Valley,
         Georgia-based corporation with annual consolidated sales of
         approximately $25 million, which, through its wholly owned subsidiary,
         SureCo, Inc., manufactures and markets traditional liquid and
         granular pesticides. Its products are sold under a variety of
         proprietary and private label brand names to commercial and consumer
         retail markets throughout North America. Commercial pesticides are
         sold principally under the All Pro brand to specialty agricultural,
         turf ornamental and professional pest control distributors. Consumer
         products are sold into the consumer retail market principally under
         the Rigo/Black Leaf brand as well as under various private label
         store-brands. The Company intends to operate SRI substantially the
         same as operated prior to the acquisition.


                                       2
<PAGE>   3

         The Company acquired all of the outstanding stock of SRI in exchange
         for 4,500,000 shares of the Company's common stock with a market
         value on the date of issuance at $1 31/64 per share. See Item 1
         above.

         The Company plans to meet operating cash requirements of the Company
         and SRI through borrowings from each entity's seasonal bank line of
         credit and from cash provided by operations.

ITEM 7.  FINANCIAL STATEMENTS, PROFORMA FINANCIAL INFORMATION AND EXHIBITS

         (a)     FINANCIAL STATEMENTS OF BUSINESS ACQUIRED
                 It is impractical to include financial statements for Southern
                 Resources, Inc. at this time. The Company intends to file, in
                 an amendment hereto, such financial statements as soon as
                 practicable but no later than 60 days from the date of this
                 filing. 

         (b)     PROFORMA FINANCIAL INFORMATION
                 It is impractical to include proforma, financial information
                 at this time. The Company intends to file, in an amendment
                 hereto, proforma financial information as soon as practicable
                 but no later than 60 days from the date of this filing.

         (c)     EXHIBITS

                  MERGER CONSIDERATION/EFFECT ON CAPITAL STOCK
 
     2.01 EFFECT ON CAPITAL STOCK.

the Merger and without any action on the part of Ringer, Merger Subsidiary, SRI,
the Surviving Corporation or the holder of any of the following shares of SRI
capital stock:
 
          (i) Each share of Common Stock, par value $1.00 per share, of SRI
     ("SRI COMMON STOCK"), issued and outstanding immediately prior to the
     Effective Time shall be converted into and become a right to receive 9,000
     shares of Common Stock, par value $.01 per share, of Ringer ("RINGER COMMON
     STOCK"); and
 
          (ii) Each share of SRI's capital stock issued and outstanding
     immediately prior to the Effective Time and owned by Ringer, Merger
     Subsidiary or SRI ("CANCELED SHARES") shall be canceled and extinguished
     without any conversion thereof and no payment shall be made with respect
     thereto.
 
The shares of Ringer Common Stock referred to in subparagraph (i) above are
collectively referred to herein as the "MERGER CONSIDERATION." The shares of SRI
Common Stock that are issued and outstanding immediately prior to the Effective
Time, other than Canceled Shares, are collectively referred to herein as the
"SHARES," and the holders thereof are referred to herein as the "HOLDERS."
 
     (b) Conversion of Merger Subsidiary Capital Stock. Each share of Common
Stock, par value $.01 per share, of Merger Subsidiary ("MERGER SUBSIDIARY
STOCK"), issued and outstanding immediately prior to the Effective Time shall be

STOCK").
 
                                        2
<PAGE>   3
 
     2.02 DEPOSIT PROCEDURES. At or prior to the Effective Time, Ringer shall
deposit or shall cause, the Merger Consideration and any dividends or
distributions relating to the Ringer Common Stock constituting a part of such
Merger Consideration to be deposited with First Trust, National Association, or
such other bank or trust company as may be designated by Ringer and acceptable
to SRI's management (the "PAYING AGENT"), for the benefit of the Holders and
Ringer to be distributed pursuant to the terms of this Agreement and the Paying
Agent Agreement (as defined in Section 12.03).
 
     2.03 HOLDBACK AND ESCROW. Ten percent (10%) of the Merger Consideration
(the "GENERAL CLAIMS HOLDBACK AMOUNT") shall be subject to Ringer's Offset Right
(as defined in Section 11.02), and an additional ten percent (10%) of the Merger
Consideration (the "SPECIFIED CLAIMS HOLDBACK AMOUNT") shall be subject to
claims with respect to Ringer's rights to indemnification as provided in the
Shareholders' Agreement (as defined in Section 12.01). The General Claims
Holdback Amount and the Specified Claims Holdback Amount (collectively the
"HOLDBACK AMOUNTS") shall be held in escrow by the First Trust, National
Association, or such other bank or trust company as may be designated by Ringer
and acceptable to SRI's management (the "ESCROW AGENT") in accordance with this
Section 2.03 and subject to Section 11.02 and the terms of the Shareholders'
Agreement.
 
     2.04 EXCHANGE PROCEDURES.
 
     (a) The Paying Agent shall distribute the Merger Consideration in exchange
for Shares pursuant to the terms of this Agreement. Ringer shall make available
to the Paying Agent from time to time as needed, cash sufficient to pay cash in
lieu of fractional shares as described in this Section 2.04 and in Section 2.05.
 
     (b) The Escrow Agent shall hold the General Claims Holdback Amount and the
Specified Claims Holdback Amount, including any dividends paid in respect
thereof prior to the Effective Time, in separate escrow accounts (respectively,
the "GENERAL CLAIMS ESCROW FUND" and the "SPECIFIED CLAIMS ESCROW FUND" and
collectively the "ESCROW FUNDS"), for the benefit of the Holders of Shares and
subject to Ringer's Offset Right pursuant to Section 11.02 (in the case of the
General Claims Escrow Fund) and rights to indemnification as provided in the
Shareholders' Agreement (in the case of the Specified Claims Escrow Fund).
Except as contemplated by this Section 2.04, Section 2.06(d), Section 11.02 and
the Shareholders' Agreement, the Escrow Funds shall not be used for any other
purpose.
 
     (c) As soon as reasonably practicable after the Effective Time, the Paying
Agent shall mail to each record holder of a certificate or certificates that
immediately prior to the Effective Time represented Shares (the "CERTIFICATES"),
(i) a letter of transmittal (which shall be in customary form) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for such Holder's Shares. The letter of transmittal shall specify that delivery
of Certificates shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent. Upon surrender of a Certificate that immediately prior to the Effective
Time represented outstanding shares of SRI Common Stock for cancellation to the
Paying Agent, together with such letter of transmittal, duly executed, and such
other documents as may be required pursuant to such instructions, the Paying
Agent shall distribute in exchange therefor, subject to escrow of the
appropriate portions thereof included in the Holdback Amounts pursuant to
Section 2.03 (the "HOLDBACK SHARES"), (i) certificates representing the number
of whole shares of Ringer Common Stock issuable to such Holder pursuant to
Section 2.01 and (ii) cash in lieu of any fractional share thereof in accordance
with Section 2.05, and the Certificate so surrendered shall forthwith be
canceled. The shares of Ringer Common Stock initially distributed to the Holders
after deducting the Holdback Amounts are referred to herein as the "INITIAL
DISTRIBUTION AMOUNTS." Until surrendered as contemplated by this Section 2.04,
each Certificate shall be deemed at any time after the Effective Time to
represent solely the right to receive the portion of the Merger Consideration
attributable to the Shares formerly represented by such Certificate.
 
     (d) If there is a transfer of Share ownership that is not registered in the
transfer records of SRI, a certificate representing the proper number of shares
of Ringer Common Stock may be issued to a person other than the person in whose
name the Certificate so surrendered is registered, if, upon presentation to the
Paying Agent, such Certificate shall be properly endorsed or otherwise be in
proper form for transfer and the person requesting such payment shall pay any
transfer or other Taxes (as defined in Section 3.15(k) hereof) required
 
                                        3
<PAGE>   4
 
by reason of the issuance of shares of Ringer Common Stock to a person other
than the registered holder of such Certificate or establish to the reasonable
satisfaction of Ringer that such tax has been paid or is not applicable.
 
     (e) Subject to the provisions of Section 11.02 and the Shareholders"
Agreement, as the case may be, in the event Ringer exercises its Offset Right
against all or a portion of the General Claims Holdback Amount as provided in
Section 11.02 or its rights to indemnification against all or a portion of the
Specified Claims Holdback Amount as provided in the Shareholders' Agreement, the
Paying Agent promptly shall distribute to Ringer from the appropriate Holdback
Amount the number of Shares of Ringer Common Stock determined by dividing the
offset amount or the indemnification amount, as the case may be, by the closing
sale price per share of the Ringer Common Stock as reported on the Nasdaq Stock
Market for the trading day immediately preceding the Effective Date. Ringer
Common Stock delivered to Ringer to fund Offset Rights or rights to
indemnification pursuant to the Shareholders' Agreement shall constitute a
post-closing reduction of the Merger Consideration rather than a payment of a
liability by Holders of Shares.
 
     2.05 NO FRACTIONAL SHARES.
 
     (a) No certificates or scrip representing fractional shares of Ringer
Common Stock shall be issued upon the surrender for exchange of Certificates,
and such fractional share interests will not entitle the owner thereof to vote
or to any rights of a shareholder of Ringer.
 
     (b) Notwithstanding any other provision of this Agreement, each Holder of
Shares exchanged pursuant to the Merger who would otherwise have been entitled
to receive a fraction of a share of Ringer Common Stock (after taking into
account all Certificates delivered by such Holder) with respect to the Initial
Distribution Amounts or the release of any portion of the Holdback Amounts shall
receive, in lieu thereof, cash (without interest) in an amount equal to such
fractional part of a share of Ringer Common Stock multiplied by the closing sale
price per share of the Ringer Common Stock as reported on the Nasdaq Stock
Market for the trading day immediately preceding the Effective Date.
 
     (c) No certificates representing fractional shares of Ringer Common Stock
shall be issued to Ringer in connection with the exercise of its Offset Right or
its rights to indemnification pursuant to the Shareholders' Agreement.
 
     2.06 OTHER EXCHANGE MATTERS.
 
     (a) Rights of Holders of SRI Capital Stock. On and after the Effective Time
and until surrendered for exchange, each Certificate representing Shares shall
be deemed for all purposes, except as provided in Section 2.05, to evidence
ownership of and to represent the right to receive such Holder's proportionate
share of the Merger Consideration to be paid therefor pursuant to Section 2.01
and Section 2.02. The record Holder of such Certificate shall, after the
Effective Time, be entitled to vote the shares of Ringer Common Stock into which
such Shares shall have been converted (including any Shares of Ringer Common
Stock then outstanding and included in the Holdback Amounts) on any matters on
which the holders of record of Ringer Common Stock, as of any date subsequent to
the Effective Date, shall be entitled to vote. After the Effective Date, there
shall be no further registration of transfers on the records of the Surviving
Corporation of outstanding certificates formerly representing Shares of SRI
Common Stock and, if a certificate formerly representing such Shares is
presented to the Paying Agent, it shall be canceled and exchanged for such
Holder's Merger Consideration as provided in Section 2.04. In any matters
relating to such Certificates, Ringer may rely conclusively upon the record of
shareholders maintained by SRI containing the names and addresses of the Holders
of record of Shares at the Effective Time.
 
     (b) Distributions with Respect to Unexchanged Shares. Ringer will pay no
dividends and make no other distributions with respect to Ringer Common Stock to
the Holder of any unsurrendered Certificate evidencing Shares of SRI Common
Stock of shares of Ringer Common Stock included in such Holder's proportionate
share of the Merger Consideration, and Ringer will make no cash payment in lieu
of fractional shares to any such Holder pursuant to Section 2.05, until the
Holder of such Certificate surrenders such Certificate. Following surrender of
any such Certificate, the Paying Agent, on behalf of Ringer, shall pay to the
record holder of the certificate representing shares of Ringer Common Stock
issued in exchange for such Certificate,
 
                                        4
<PAGE>   5
 
without interest, (i) at the time of such surrender, the amount of any cash
payable in lieu of a fractional share of Ringer Common Stock to which such
holder is entitled pursuant to Section 2.05 and the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with
respect to such whole shares of Ringer Common Stock, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
after the Effective Time but prior to such surrender and a payment date
subsequent to such surrender payable with respect to such whole shares of Ringer
Common Stock.
 
     (c) No Further Ownership Rights in SRI Capital Stock. The Merger
Consideration delivered upon the surrender for exchange of Shares in accordance
with the terms hereof (including any cash paid pursuant to Section 2.05 or
Section 2.06(b)) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such Shares.

Ringer upon demand any portion of the Merger Consideration that remains
undistributed by the Paying Agent more than one year after the Effective Time.
Holders of Certificates who have not theretofore complied with this Article II

Consideration as to which they may be entitled under Section 2.01 and Section
2.02, including any dividends or distributions with respect to Ringer Common
Stock.
 
     (e) No Liability. None of Ringer, Merger Subsidiary, SRI, the Escrow Agent
or the Paying Agent shall be liable to any person in respect of any shares of
Ringer Common Stock (or dividends or distributions with respect thereto) or cash

applicable abandoned property, escheat, or similar law.

destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen, or destroyed, and, if required by the
Surviving Corporation, upon the delivery to the Paying Agent of a bond in such
sum as the Surviving Corporation may direct as indemnity against any claim that
may be made against it with respect to such Certificate, the Paying Agent will
issue in exchange for such lost, stolen, or destroyed Certificate the Merger
Consideration and any cash in lieu of fractional shares, and unpaid dividends
and distributions on shares of Ringer Common Stock deliverable in respect
thereof, pursuant to this Agreement.
 
     (h) Stock Transfer Books. At the Effective Time, the stock transfer books
of SRI shall be closed and there shall be no further registration of transfers
of shares of SRI's capital stock thereafter on the records of SRI. From and

SRI's capital stock immediately prior to the Effective Time shall cease to have
any rights with respect to such shares of SRI's capital stock except as
otherwise provided in this Agreement or by law.
 
     (i) Adjustments. If, between the date hereof and the date on which the last
payment of either Holdback Amount is made (the "LAST PAYMENT DATES"), shares of
Ringer Common Stock shall be changed into a security of a different issuer, a
different class of shares or cash by reason of any reclassification,
recapitalization, split-up, combination, exchange of shares, readjustment,

unincorporated organization, or government or political subdivision thereof)
under the provisions of the articles of incorporation or bylaws of SRI or any
Subsidiary or any contract, indenture, mortgage, lease, loan agreement or other
agreement, relationship, commitment, arrangement or instrument, written or oral,

or regulation or order, judgment or decree to which SRI or any Subsidiary is
subject.
 
     3.06 GOVERNMENTAL AUTHORITIES; CONSENTS. Except for the filing of the
Certificate of Merger with the Secretary of State of the State of Georgia,
neither SRI nor any Subsidiary is required to submit any notice, report or other
filing with any governmental authority in connection with the execution or
delivery by SRI of this Agreement, the Certificate of Merger or the SRI
Ancillary Agreements or the consummation of the transactions contemplated hereby

regulatory authority is required to be obtained by SRI or any Subsidiary in

     3.07 CAPITAL STOCK OF SRI.
 
     (a) On the date hereof, the authorized capital stock of SRI consists of
100,000 shares of SRI Common Stock, par value $.10, of which, as of the date
hereof, 500 shares are issued and outstanding. On the date hereof, SRI's capital
stock is held of record by the persons and in the amounts set forth in the
Disclosure Schedule. On the Effective Date, SRI's capital stock will be held of
record by the persons and in the amounts set forth in a disclosure schedule to

SRI's capital stock (i) have been duly authorized and are validly issued, fully
paid and nonassessable, (ii) are not subject to preemptive rights created by
statute, SRI's articles of incorporation or bylaws, or any other agreement to
which either SRI or, to the knowledge of SRI, SRI's shareholders are bound, and
(iii) were not issued in violation of any applicable securities laws that would
subject the Surviving Corporation to fines, penalties, or rescission or civil
damages that are material in amount. As used in this Agreement, "knowledge of
SRI" and similar words to that effect shall mean the actual knowledge of the
officers and directors of SRI and each of the Subsidiaries after due inquiry.
 
     (b) There are no rights, subscriptions, warrants, options, conversion
rights or agreements of any kind outstanding to purchase or otherwise acquire
from SRI any shares of SRI's capital stock or other securities of SRI of any
kind ("OUTSTANDING PURCHASE RIGHTS") (and there are no agreements or other
obligations of SRI to grant any Outstanding Purchase Rights), and there are no
agreements or other obligations (contingent or otherwise) that may require SRI
to repurchase or otherwise acquire any shares of SRI's capital stock.
 
     (c) The Disclosure Schedule sets forth those persons who are, in SRI's
reasonable judgment, "affiliates" of SRI within the meaning of Rule 145
promulgated by the SEC under the Securities Act of 1933, as amended (the
"SECURITIES ACT").

Subsidiaries (the "LATEST BALANCE SHEET") and the unaudited consolidated
statements of earnings, Shareholders equity and cash flows of SRI and the
Subsidiaries for the fiscal year ended October 3, 1997 (such statements and the
Latest Balance Sheet being herein referred to as the "LATEST FINANCIAL

30, 1996 and September 30, 1995, of SRI and the Subsidiaries and the audited
consolidated statements of earnings, Shareholders equity and cash flows of SRI

SRI and
 
                                        7
<PAGE>   8
 
the Subsidiaries and fairly present the financial condition of SRI and the
Subsidiaries as of the dates thereof and respective results of operations for
the periods referred to therein. The Annual Financial Statements (including the
notes thereto) have been prepared in accordance with GAAP, consistently applied
through the periods indicated (except as indicated in the notes thereto), and
the Latest Financial Statements have been prepared in accordance with GAAP (as
such term applies to unaudited interim financial statements and thus such
statements may not contain all notes and may not contain prior period
comparative data which are required to be prepared in accordance with generally
accepted accounting principles in general and subject to normal year-end audit
adjustments), are consistent with the Annual Financial Statements.
 
     3.09 ABSENCE OF UNDISCLOSED LIABILITIES. Except as reflected in the Latest
Balance Sheet, neither SRI nor any Subsidiary has any liabilities (whether
accrued, absolute, contingent, unliquidated or otherwise, whether due or to
become due, whether known or unknown, and regardless of when asserted) arising
out of transactions or events heretofore entered into, or any action or
inaction, or any state of facts existing, with respect to or based upon
transactions or events heretofore occurring, except liabilities which have
arisen after the date of the Latest Balance Sheet in the ordinary course of
business (none of which is a material uninsured liability for breach of
contract, breach of warranty, tort, infringement, claim or lawsuit).
 
     3.10 NO MATERIAL ADVERSE CHANGES. Since the date of the Latest Balance
Sheet (the "Balance Sheet Date"), with the exception of seasonal business
changes in the ordinary course, there has been no material adverse change in the
assets, financial condition, operating results, distributor, customer, employee
or supplier relations, business condition or prospects of SRI and the
Subsidiaries, taken as a whole.

     3.12 TITLE TO PROPERTIES.
 
     (a) The real property listed as owned ("OWNED PROPERTY") or leased ("LEASED
PROPERTY") in the Disclosure Schedule constitutes all of the real property now
used or occupied by SRI or any Subsidiary, and ever owned used or occupied in
the past by SRI or any Subsidiary (including any and all structures, fixtures or
other improvements thereon, the "REAL PROPERTY"). Such Disclosure Schedule
includes the record title holder, location, uses thereof and SRI or Subsidiary
indebtedness thereon, if any, for all Real Property. SRI or a Subsidiary has
good and marketable fee simple title to all Owned Property, except for recorded
easements, covenants and other restrictions; utility easements; building
restrictions; zoning restrictions; and other easements, covenants and
restrictions existing generally with respect to properties of a similar
character, all of which are shown on such Disclosure Schedule and there are no
outstanding options to purchase the Owned Real Property. The Real Property has
access, sufficient for the conduct of the business of SRI as now conducted or as
presently proposed to be conducted, to public roads and to all utilities,
including electricity, sanitary and storm sewer, potable water, natural gas and
other utilities, used in the operation of the business of SRI at that location.
All structures, fixtures and other improvements on all Owned Property are within
the lot lines and do not encroach on the properties of any other Person, and the
use and operation of all Owned Property are not in violation of any applicable
building, zoning, safety, environmental, subdivision and other laws, ordinances,
regulations, codes, permits, licenses and certificates and all restrictions and
conditions affecting title. Except as described in the Disclosure Schedule, no
portion of any Owned Property is located in a flood plain, flood hazard area or
designated wetlands area. Since January 1, 1992, neither SRI nor any Subsidiary
has received any written or oral notice of assessments for public improvements
against any Owned Property or any written or oral notice or order by any
governmental body, any insurance company that has issued a policy with respect
to any of such properties or any board of fire underwriters or other body
exercising similar functions (other than as disclosed in the insurance reports
disclosed hereunder) that (i) relates to material violations of building, safety
or fire ordinances or regulations, (ii) claims any material defect or deficiency
with respect to any of such properties or (iii) requests that performance of any
material repairs, alterations or other work to or in any of such properties or
in the streets bounding the same. Complete and correct copies of all material
written reports on such matters from any insurance company that has issued a
policy with respect to any of such properties since January 1, 1994, have been
delivered to Ringer. To the knowledge of SRI, there is no pending condemnation,
expropriation, eminent domain or similar proceeding affecting all or any portion
of the Owned Property.
 
     (b) The leases for the Leased Property (the "LEASES") are in full force and
effect, and SRI or a Subsidiary holds a valid and existing leasehold interest
under each of the Leases for the term set forth in the Disclosure Schedule. SRI
has delivered to Ringer complete and accurate copies of each of the Leases, and
none of the Leases has been modified in any respect, except to the extent that
such modifications are disclosed by the copies delivered to Ringer. Neither SRI
nor any Subsidiary is in material default, and to the knowledge of SRI no
circumstances exist which, if unremedied, would, either with or without notice
or the passage of time or both, result in such default under any of the Leases;
nor to the knowledge of SRI is any other party to any of the Leases in default.
 
     (c) SRI or a Subsidiary owns good and marketable title to each of the
tangible properties and tangible assets reflected on the Latest Balance Sheet or
acquired since the date thereof, free and clear of all liens and encumbrances,
except for (i) liens for current Taxes not yet delinquent, (ii) liens set forth
in the Disclosure Schedule, (iii) the properties subject to the Leases, (iv)
assets disposed of since the date of the Latest Balance Sheet in the ordinary
course of business, (v) liens imposed by law and incurred in the ordinary course
of business for obligations not yet due to carriers, warehousemen, laborers and
materialmen and (vi) liens in respect of pledges or deposits under workers'
compensation laws, all of which liens aggregate less than $25,000.
 
     (d) All of the buildings, machinery, equipment, tools, jigs, fixtures,
vehicles and other tangible assets necessary for the conduct of the business of
SRI and the Subsidiaries are in reasonable working condition and repair,
ordinary wear and tear excepted, and are usable in the ordinary course of
business. There are no defects in such assets or other conditions relating
thereto which adversely affect the operation or value of such assets. SRI or a
Subsidiary owns or leases under valid leases, all buildings, machinery,
equipment and other tangible
 
                                       10
<PAGE>   11
 
assets necessary for the conduct of its business as presently conducted, except
for defects of title that do not materially affect the use of such assets by SRI
and the Subsidiaries and except for such assets that can be purchased or leased
for nominal expenditures.
 
     3.13 ACCOUNTS RECEIVABLE. The accounts receivable reflected on the Latest
Balance Sheet and those arising thereafter are valid receivables, are not
subject to valid counterclaims or set-offs, and are collectible in accordance
with their terms, except to the extent of the bad debt reserve reflected on the
Latest Balance Sheet.
 
     3.14 INVENTORY. The inventory of raw materials, work in process and
finished goods of SRI and each Subsidiary consists of items of a cost, quality
and quantity usable and, with respect to finished goods only, salable at the
normal profit levels of SRI and such Subsidiary in the ordinary course of the
business of SRI and such Subsidiary. The inventory of finished goods of SRI and
each Subsidiary is not slow-moving as determined in accordance with past
practices, obsolete or damaged and is merchantable and fit for its particular
use. SRI and each Subsidiary has on hand or has ordered and expects timely
delivery of such quantities of raw materials, and has on hand such quantities of
work in process and finished goods, in each case as are reasonably required to
timely fill current orders on hand which require delivery within 60 days and to
maintain the manufacture and shipment of products at its normal level of
operations. As of the date of the Latest Balance Sheet, the values at which such
inventory is carried on the Latest Balance Sheet are in accordance with GAAP.
The Disclosure Schedule contains a materially complete and accurate summary of
SRI's and each Subsidiary's inventory of raw materials, work in progress,
finished goods and reserve for obsolete and other inventory allowance or accrual
calculation schedules as of September 30, 1996 and October 3, 1997. The
book-to-physical inventory adjustment (i.e., the difference, if any, obtained by
subtracting the value of the physical inventory at cost from the general ledger
inventory balance) as of the Balance Sheet Date will not exceed $100,000 (the
amount of any such shortfall being referred to herein as the "Inventory
Adjustment Amount").
 
     3.15 TAX MATTERS.
 
     (a) Each of SRI, each Subsidiary and any affiliated, combined or unitary
group of which SRI or any Subsidiary is or was a member, any predecessor of SRI
or any Subsidiary, and any Plans (as defined in Section 3.21 hereof), as the
case may be (each, a "TAX AFFILIATE" and, collectively, the "TAX AFFILIATES"),
has: (i) timely filed (or has had timely filed on its behalf) all returns,
declarations, reports, estimates, information returns, and statements
("RETURNS") required to be filed or sent by it in respect of any Taxes or
required to be filed or sent by it by any taxing authority having jurisdiction
and all such Returns are true and correct in all material respects, except for
timing and categorization issues that would not have a Material Adverse Effect;
(ii) timely and properly paid (or has had paid on its behalf) all Taxes due and
payable with respect to the periods covered by such Returns; (iii) established
on its Latest Balance Sheet, in accordance with GAAP, reserves that are adequate
for the payment of any Taxes not yet due and payable for all Tax periods or
portions thereof ending on, prior to, or including the Closing Date, the amount
of which as of the Latest Balance Sheet Date is set forth in the Disclosure
Schedule; and (iv) complied with all applicable laws, rules, and regulations
relating to the withholding of Taxes and the payment thereof (including, without
limitation, withholding of Taxes under Sections 1441 and 1442 of the Code, or
similar provisions under any foreign laws), and timely and properly withheld
from individual employee wages or other payments to employees and paid over to
the proper governmental authorities all amounts required to be so withheld and
paid over under all applicable laws. True and correct copies of any and all
Returns filed by any Tax Affiliate have been provided to Ringer.
 
     (b) There are no liens for Taxes upon any assets of SRI or any Subsidiary
or of any Tax Affiliate, except liens for Taxes not yet due. Neither SRI nor any
Subsidiary is a party to any tax sharing agreement or similar arrangement for
the payment or reimbursement of Taxes.
 
     (c) No deficiency for any Taxes has been asserted, assessed or, to SRI's
knowledge, proposed against SRI, any Subsidiary or any Tax Affiliate that has
not been resolved and paid in full. No waiver, extension or comparable consent
given by SRI, any Subsidiary or any Tax Affiliate regarding the application of
the statute of limitations with respect to any Taxes or Returns is outstanding,
nor is any request for any such waiver or consent pending. There has been no Tax
audit or other administrative proceeding or court proceeding with
 
                                       11
<PAGE>   12
 
regard to any Taxes or Returns, nor is any such Tax audit or other proceeding
pending, nor has there been any notice to SRI or any Subsidiary by any Taxing
authority regarding any such Tax, audit or other proceeding, or, to the
knowledge of SRI, is any such Tax audit or other proceeding threatened with
regard to any Taxes or Returns. SRI does not expect the assessment of any
additional Taxes of SRI, any Subsidiary or any Tax Affiliate and is not aware of
any unresolved questions, claims or disputes concerning the liability for Taxes
of SRI, any Subsidiary or any Tax Affiliate which would exceed the estimated
reserves established on its books and records.
 
     (d) Neither SRI, any Subsidiary nor any Tax Affiliate is a party to any
agreement, contract or arrangement that would result, separately or in the
aggregate, in the payment of any "excess parachute payments" within the meaning
of Section 280G of the Code, and the consummation of the transactions
contemplated by this Agreement will not be a factor causing payments to be made
by SRI, any Subsidiary or any Tax Affiliate that are not deductible (in whole or
in part) under Section 280G of the Code.
 
     (e) Neither SRI, any Subsidiary nor any Tax Affiliate has requested any

     (a) SRI shall give prompt notice to Ringer of (i) the occurrence or failure
to occur of any event or the discovery of any information, which occurrence,
failure or discovery would be likely to cause any representation or warranty by
SRI contained in this Agreement to be untrue, inaccurate or incomplete after the
date hereof in any material respect or, in the case of any representation or
warranty given as of a specific date, would be likely to cause any such
representation or warranty on its part contained in this Agreement to be untrue,
inaccurate or incomplete in any material respect as of such specific date, and
(ii) any material failure of SRI to comply with or satisfy any covenant or
agreement to be complied with or satisfied by it hereunder.
 
     (b) From time to time after the date hereof and prior to the Effective
Time, SRI shall promptly supplement or amend any of its representations and
warranties which apply to the period after the date hereof by delivering an
updated Disclosure Schedule to Ringer pursuant to this Section 5.8(b) with
respect to any matter hereafter arising which would render any such
representation or warranty after the date of this Agreement materially untrue,
inaccurate or incomplete as a result of such matter arising. Such supplement or
amendment to SRI's representations and warranties contained in an updated
Disclosure Schedule delivered pursuant to this Section 5.8(b) shall be deemed to
have modified the representations and warranties of SRI, and no such supplement
or amendment, or the information contained in such updated Disclosure Schedule,
shall constitute a breach of a representation or warranty of SRI; provided that
no such supplement or amendment may cure any breach of a covenant or agreement
of SRI under Articles V or VI. Within 15 days after receipt of such supplement
or amendment, Ringer may terminate this Agreement pursuant to Section 9.01(h)
hereof if the information in such supplement or amendment together with the
information in any and all of the supplements or amendments previously provided
by SRI indicate that SRI has suffered or is reasonably likely to suffer a
material adverse change (as described in Section 9.01(h).

                        THE SHAREHOLDERS' REPRESENTATIVE
 
     10.01 APPOINTMENT. As used in this Agreement, the "SHAREHOLDERS'
REPRESENTATIVE" shall mean David K. Vansant, or any person appointed as a
successor Shareholders' Representative pursuant to Section 10.02 hereof.
 
     10.02 ELECTION AND REPLACEMENT. During the period ending upon the date when
all obligations under this Agreement have been discharged (including all
obligations pursuant to Section 11.02 hereof), SRI's Holders who, held a
majority of the aggregate voting power of the Shares (a "MAJORITY"), may, from
time to time upon written notice to the Shareholders' Representative and Ringer,
remove the Shareholders' Representative
 
                                       31
<PAGE>   32
 
or appoint a new Shareholders' Representative to fill any vacancy created by the
death, incapacitation, resignation or removal of the Shareholders'
Representative. Furthermore, if the Shareholders' Representative dies, becomes
incapacitated, resigns or is removed by a Majority, the Majority shall appoint a
successor Shareholders' Representative to fill the vacancy so created. If the
Majority fails to appoint such successor within 10 business days after a written
request by Ringer to appoint such successor, then Ringer shall appoint such
successor, and shall advise Holders who held Shares of such appointment by
written notice. A copy of any appointment by the Majority of the Shareholders'
Representatives of any successor Shareholders' Representative shall be provided
to Ringer promptly after it shall have been effected.
 
     10.03 AUTHORITY. On behalf of the Holders, the Shareholders' Representative
shall be authorized to take action and to make and deliver any certificate,
notice, consent or instrument required or permitted to be made or delivered
under this Agreement or under the documents referred to in this Agreement (an
"INSTRUMENT"), which the Shareholders' Representative determines in his
discretion to be necessary, appropriate or desirable, and, in connection
therewith, to hire or retain, at the sole expense of the Holders, such counsel,
investment bankers, accountants, representatives and other professional advisors
as they determine in their sole and absolute discretion to be necessary,
advisable or appropriate in order to carry out and perform their rights and
obligations hereunder. Any party receiving an Instrument from the Shareholders'
Representative shall have the right to rely in good faith upon such Instrument,
and to act in accordance with the Instrument without independent investigation.
 
     10.04 NO LIABILITY OF RINGER. Ringer and the Surviving Corporation shall
have no liability to any shareholder of SRI or otherwise arising out of the acts
or omissions of the Shareholders' Representative or any disputes among SRI's
shareholders. Ringer and the Surviving Corporation shall have no direct
liability to SRI's shareholders under this Agreement or the other agreements
referred to herein and may rely entirely on their dealings with, and notices to
and from, the Shareholders' Representative to satisfy any obligations Ringer and
the Surviving Corporation might have under this Agreement, any agreement
referred to herein or otherwise to SRI's shareholders. Without limiting the
foregoing, delivery to the Escrow Agent of a portion of the Merger Consideration
shall extinguish any obligations of Ringer to SRI's shareholders with respect to
such portion, and Ringer shall have no liability for subsequent misdelivery to
any shareholder of SRI by the Paying Agent or any act or omission of the
Shareholders' Representative with respect to such cash or certificates.
 
                                   ARTICLE XI

investigation made by or on behalf of any of the parties hereto or the results
of any such investigation and notwithstanding the participation of such party in
the Closing, the representations and warranties of SRI contained in, or attached
to, this Agreement shall survive the Closing until the date upon which Ringer's
Accountant shall first release its audit report with respect to financial
consolidated financial statements of Ringer and its subsidiaries that include
SRI and the Subsidiaries (the "Offset Period") and shall have no further force
or effect thereafter.
 
     11.02 RIGHT OF OFFSET.
 
     (a) Subject to Section 11.02(f) hereof, Ringer shall have a right to offset
(the "OFFSET RIGHT"), from time to time, its "Losses" (as hereinafter defined)
against the General Claims Holdback Amount with respect to any loss, liability,
deficiency, damage, expense or cost (including reasonable legal expenses),
whether or not actually incurred or paid during the Offset Period (collectively,
the "LOSSES"), which Ringer, the Surviving Corporation or any of their
respective affiliates, officers, directors, employees or agents (the "PROTECTED
PARTIES") suffers, sustains or becomes subject to, as a result of:
 
          (i) Any misrepresentation (a "MISREPRESENTATION") in any of the
     representations and warranties of SRI contained in this Agreement or in any
     of the exhibits, schedules, agreements, certificates and other documents
     delivered or to be delivered by or on behalf of SRI pursuant to this
     Agreement or otherwise attached to, or referenced or incorporated in, this
     Agreement (collectively, the "RELATED DOCUMENTS");
 
                                       32
<PAGE>   33
 
          (ii) Any breach (a "BREACH") of, violation of, or failure to perform,
     any agreement or covenant of SRI contained in this Agreement or any of the
     Related Documents prior to the Effective Time;
 
          (iii) Any Claim (as defined in Section 11.02(c) hereof) or threatened
     Claim against the Protected Parties arising out of actions or inactions of
     SRI with respect to SRI's business or the Real Property prior to the
     Effective Time, including, but not limited to, all products liability
     Claims arising out of actions or inactions prior to such time; and
 
          (iv) Notwithstanding anything to the contrary contained in this
     Section 11.02, the Ringer shall not exercise its Offset Right with respect
     to any Loss other than the Inventory Adjustment Amount unless and until the
     total amount of Losses, not taking into account the Inventory Adjustment
     Amount, shall exceed $25,000, in which event it may exercise such right
     with respect to the entire aggregate amount of Losses other than the
     Inventory Adjustment Amount that equal or exceed $25,000.
 
Notwithstanding the foregoing, Losses as defined in this Section 11.02(a) shall
be reduced by the amount of any benefits or other similar payments received by
SRI or the Protected Parties from insurance companies insuring the claim that is
the subject of the Loss.
 
     (b) Ringer may exercise its Offset Right, from time to time, in accordance
with the procedures set forth in paragraphs (c) and (d) of this Section 11.02,
against any payment or payments to be made out of the General Claims Holdback
Amount. Each time, if any, that Ringer exercises its Offset Right, Ringer shall
promptly deliver to the Shareholders' Representative a schedule signed by an
officer of Ringer reflecting the revised payments, after giving effect to such
exercise of its Offset Right, to be made to the Holders out of the General
Claims Holdback Amount. In the event Ringer exercises its Offset Right with
respect to Losses as a result of, in connection with or related to, any of the
matters described in Section 11.02(a) above, such offset shall be applied
against any payment or payments to be made out of the General Claims Holdback
Amount.
 
     (c) In the event any of the Protected Parties becomes involved in any
legal, governmental or administrative proceeding which may result in Losses, or
if any such proceeding is threatened or asserted (any such third party action or
proceeding being referred to herein as a "CLAIM"), Ringer shall promptly notify
the Shareholders' Representative in writing of the nature of any such Claim and
Ringer's estimate of the Losses arising therefrom.
 
          (i) The Shareholders' Representatives shall be entitled to contest and
     defend such Claim; provided, that the Shareholders' Representative has a
     reasonable basis for concluding such defense may be successful and
     diligently contests and defends such Claim; provided, further, that, Ringer
     in its sole and absolute discretion, may notify the Shareholders'
     Representatives at any time that any such contest or defense must be
     immediately terminated, in which case Ringer's Offset Right with respect to
     such Claim shall thereupon terminate. Notice of the intention so to contest
     and defend shall be given by the Shareholders' Representative to Ringer
     within 20 days after Ringer provides notice of such Claim (but, in all
     events, at least five business days prior to the date that an answer to
     such Claim is due to be filed). Such contest and defense shall be conducted
     by reputable attorneys employed by the Shareholders' Representative. Ringer
     shall be entitled at any time, at its own cost and expense (which expense
     shall not constitute a Loss unless the Shareholders' Representatives are
     not adequately representing or, because of a conflict of interest between,
     may not adequately represent, any interests of the Protected Parties, and
     only to the extent that such expenses are reasonable), to participate in
     such contest and defense and to be represented by attorneys of its own
     choosing. If Ringer elects to participate in such defense, Ringer shall
     cooperate with the Shareholders' Representative in the conduct of such
     defense. Neither Ringer nor the Shareholders' Representative may concede,
     settle or compromise any Claim without the consent of the other, which
     consent shall not be unreasonably withheld; provided, that the
     Shareholders' Representative may, without the consent of Ringer, settle any
     Claim which is solely for money damages if the Shareholders' Representative
     acknowledges that such Claim gives rise to a Loss that is subject to
     Ringer's Offset Right hereunder and if the entire amount of the settlement
     amount may be recovered by Ringer by means of Ringer's Offset Rights
     hereunder. The Shareholders' Representatives shall have the right to have
     the cost of defense, including reasonable legal expenses, paid or
     reimbursed through the exercise of Ringer's Offset Rights. A request for
     payment or reimbursement thereof shall constitute the
 
                                       33
<PAGE>   34
 
     acknowledgment of the Shareholders' Representative that such costs
     constitutes a Loss that is subject to Ringer's Offset Rights.
     Notwithstanding anything herein to the contrary, such Offset Rights shall
     not be subject to the deductibles described in Section 11.02(b).
 
          (ii) Notwithstanding the foregoing, if: (A) a Claim seeks equitable
     relief against any of the Protected Parties, (B) the subject matter of a
     Claim relates to the ongoing business of any of the Protected Parties,
     which Claim, if decided against such Protected Party, would materially
     adversely affect the ongoing business or reputation of such Protected
     Party, or (C) the estimated Losses of the Protected Parties related to the
     Claim exceed the amount Ringer may recover using its Offset Right
     hereunder, then, in each such case, Ringer alone shall be entitled to
     contest, defend and settle such Claim in the first instance and, if Ringer
     does not contest, defend or settle such Claim, Shareholders' Representative
     shall have the right to contest and defend (but not settle) such Claim.
 
     (d) In the event Ringer (on behalf of itself or any Protected Party) should
have a claim giving rise to an Offset Right that does not involve a Claim,
Ringer shall deliver a notice (the "OFFSET NOTICE") of such claim with
reasonable promptness to the Shareholders' Representative and the Escrow Agent.
The Offset Notice shall include an estimate of Ringer's Losses relating to such
claim. If the Shareholders' Representative notifies Ringer that the
Shareholders' Representative does not dispute the claim described in the Offset
Notice, or if the Shareholders' Representative fails to notify Ringer within 20
days after delivery of the Offset Notice of any such dispute with respect to
such claim, the Losses in the amount specified in the Offset Notice will be
conclusively deemed Losses and Ringer may exercise its Offset Right with respect
to such amount in accordance with the Offset Notice. If the Shareholders'
Representative has timely disputed such claim, Ringer and the Shareholders'
Representative will proceed in good faith to negotiate a resolution of such
dispute, and if not resolved through the negotiations of such representatives
within 60 days after the date of the Offset Notice of such claim, the parties
agree to resolve such dispute through binding arbitration in accordance with
Section 13.05.
 
     (e) In the event of a Claim under Section 11.02(c) or a dispute relating to
the Offset Notice under Section 11.02(d), the Escrow Agent will retain property
then held by it in escrow under this Agreement in an amount sufficient to
satisfy the estimated value of such Claim or disputed Offset Notice until the
resolution of such Claim or dispute.
 
     (f) Notwithstanding anything contained in this Agreement to the contrary,
the right of Ringer to exercise its Offset Right hereunder shall be subject to
the following limitations:
 
          (i) Ringer shall not be entitled to exercise its Offset Right with
     respect to any Losses unless Ringer delivers to the Shareholders'
     Representatives an Offset Notice under Section 11.02(d) or notice of a
     Claim under Section 11.02(c) relating to such Losses prior to the end of
     the Offset Period.
 
          (ii) Except as provided in the Shareholders' Agreements, the Offset
     Right shall be Ringer's sole and exclusive remedy with respect to any
     Losses that any Protected Party may suffer, sustain or become subject to
     pursuant to the terms of this Agreement, and Ringer agrees that it shall
     not, and hereby waives all rights to, institute or maintain any suit,
     proceeding or action against the Holders or utilize or exercise any other
     legal or equitable remedy for the purpose of recovering damages or other
     relief with respect to any Losses (including, without limitation, an action
     seeking to recover any portion of the purchase price previously paid to
     SRI's shareholders) except for suits, proceedings or actions necessary to
     enforce or implement the Offset Right; provided that, (A) nothing herein
     shall prevent a party from bringing an action based upon allegations of
     fraud or other intentional misconduct with respect to another party hereto
     in connection with this Agreement, and (B) nothing herein shall limit in
     any manner any other legal rights or remedies which any Protected Party
     which is a party to an agreement identified under Article XII has against
     another party to such agreement in accordance with the terms and conditions
     provided therein.

     13.05 ARBITRATION. In the event this Section 13.05 is applicable to any
dispute between the parties, the parties agree to resolve such dispute through
binding arbitration by a single arbitrator pursuant to the Commercial
Arbitration Rules of the American Arbitration Association. The arbitration shall
be conducted in Minneapolis, Minnesota. Any award rendered shall be final and
conclusive upon the parties and a judgment thereon may be entered in any court
of competent jurisdiction. All costs and expenses, including reasonable
attorneys' fees and experts' fees, of all parties incurred in any dispute which
is determined by arbitration pursuant to this Section 13.05 shall be borne by
the party determined to be liable in respect of such dispute; provided, however,
that if complete liability is not assessed against only one party, the parties
shall share the total costs in proportion to their respective amounts of
liability so determined. Except where clearly prevented by the area in dispute,
both parties agree to continue performing their respective obligations under
this Agreement while the dispute is being resolved. All negotiation and
arbitration proceedings under this Section 13.05 shall be treated as
confidential information in accordance with the provisions of the
confidentiality agreement between Ringer and SRI, dated August 15, 1997 (the
"CONFIDENTIALITY AGREEMENT"). Any arbitrator shall be bound by an agreement
containing confidentiality provisions at least as restrictive as those contained
in the Confidentiality Agreement. Nothing herein shall preclude a party hereto
from seeking equitable relief to prevent any immediate, irreparable harm to its
interest, including multiple breaches of this Agreement or the Related
Documents. Otherwise, these procedures are exclusive and shall be fully
exhausted prior to the initiation of any litigation. Either party may seek
specific enforcement of any arbitrator's decision under this Section 13.05. The
other party's only defense to such a request for specific enforcement shall be
fraud by or on the arbitrator.
 
     13.06 ASSIGNMENT. This Agreement and all of the provisions hereof will be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns, except that neither this Agreement nor any of
the rights, interests or obligations hereunder may be assigned by any party
hereto without the prior written consent of the other parties hereto.
 
     13.07 SEVERABILITY. Whenever possible, each provision of this Agreement
will 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 prohibited by or
invalid under applicable law, such provision will be ineffective only to the
extent of such
 
                                       36
<PAGE>   37
 
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement.
 
     13.08 COMPLETE AGREEMENT. This Agreement, the Certificate of Merger and the
Related Agreements and other exhibits hereto, the Disclosure Schedule and the
other documents referred to herein contain the complete agreement between the
parties and supersede any prior understandings, agreements or representations by
or between the parties, written or oral, which may have related to the subject
matter hereof in any way; provided, that the Confidentiality Agreement shall
remain in force and effect without modification thereof.
 
     13.09 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, any one of which need not contain the signatures of more than one
party, but all such counterparts taken together will constitute one and the same
instrument. Any such counterpart may be delivered by facsimile. Any party
delivering a counterpart by facsimile shall deliver an original copy within 48
hours, provided that the failure to so deliver an original shall not effect the
enforceability of this agreement against such party.
 
     13.10 GOVERNING LAW. The internal law, without regard for conflicts of laws
principles, of the State of Minnesota will govern all questions concerning the
construction, validity and interpretation of this Agreement and the performance
of the obligations imposed by this Agreement.
 
     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.
