                                       2
<PAGE>   3

the parties hereto that all liabilities and obligations that Seller has or may
have in the future (whether accrued, absolute, contingent, unliquidated, or
otherwise, whether or not known to Seller, and whether due or to become due),
other than the Assumed Obligations, shall be and remain the liabilities and
obligations of Seller. Without limiting the generality of the foregoing, Buyer
shall not assume or in any way be liable or responsible for: (a) servicing any
equipment other than Hitachi DX and HCX switches and Centigram voice mail
systems and any other "peripheral equipment" attached to such switches ; (b) any

of Seller arising in connection with the Service Base; or (c) any liability or
obligation of Seller under any Service Contract, Non-Contract Service Right, or

prior to such Effective Date.

         1.4      Purchase Price and Payment. In consideration of the transfer
by Seller to Buyer of the Assets, and in addition to the assumption of the
Assumed Obligations, Buyer shall pay to Seller the aggregate purchase price of
Two Million Two Hundred Seventy-Five Thousand Dollars ($2,275,000) (the
"Purchase Price"), subject to adjustment pursuant to Section 1.5 below. The
Purchase Price shall be paid in cash as follows: (a) at Closing, Buyer shall pay
Seller the sum of One Million Eight Hundred Sixty Thousand Dollars ($1,860,000)
less a credit equal to the amount of Prepaid Fees, a detailed list of which is
attached hereto as Schedule 1.4, and (b) the balance due after adjustment of the
Purchase Price pursuant to Section 1.5 below, shall be paid within sixty (60)
days after expiration of the Transition Period (as defined in Section 2.2(a)).
Such payment shall be accompanied by a written accounting of any adjustment to
the Purchase Price in accordance with Section 1.5 below, together with a list of
those items of Inventory that failed testing and a reasonable explanation
therefore.

         1.5      Adjustment of Purchase Price.

         (a)      The Purchase Price shall be reduced by an amount equal to the
itemized price shown on Schedule 1.1(c) hereto for each item of Inventory
eliminated from the Assets to be transferred to Buyer, due to the testing
requirement of Section 1.1(c) or Seller's use of such item during the Transition
Period pursuant to Section 2.2(b) below.

         (b)      In the event that Seller does not, within ninety (90) days
after the Closing, obtain and deliver to Buyer the necessary customer consents
to assignment of those Service Contracts listed on Schedule 3.8(b), any such
Service Contract(s) for which consents have not been obtained shall be omitted
from the Assets to be transferred hereunder, and the Purchase Price shall be
reduced by an amount, calculated as of the Closing Date, equal to:

          Monthly Service Fee
           under such Service
               Contract(s)         x    $2,185,000.00
          -------------------
                $152,682



                                       3
<PAGE>   4

Furthermore, within thirty (30) days after said 90-day period, Seller shall
reimburse Buyer for any services performed by Buyer under such omitted Service
Contract(s), as invoiced to Seller at Buyer's prevailing rates.

         1.6      Allocation of Purchase Price. The Purchase Price shall be
allocated among the Assets as set forth on Schedule 1.6 (subject to a reduction
in the amount allocated to Inventory consistent with the adjustment, if any,
made to the Purchase Price in accordance with Section 1.5 above). Seller and
Buyer shall report the transactions contemplated hereby on all tax returns in a
manner consistent with such allocation.

         1.7      Instruments of Conveyance. In order to effect the transfer of
the Assets contemplated by this Agreement, at the Closing, Seller shall execute
and deliver to Buyer all such bills of sale, certificates of title and other
documents or instruments of assignment, transfer or conveyance as Buyer shall
reasonably deem necessary or appropriate to vest in or confirm to Buyer good and
marketable title to the Assets, free and clear of all liens, claims and
encumbrances.

                                   ARTICLE II

                          CLOSING AND TRANSITION PERIOD

         2.1      Closing. The closing of the transactions contemplated hereby
(the "Closing") shall take place at the offices of Barber & Bartz in Tulsa,
Oklahoma at 10:00 a.m. on September 17, 1998, or at such other time or place or
on such other date as the parties may agree in writing. The date of Closing is
referred to herein as the "Closing Date."

         2.2      Transition Period.

         (a)      In order to facilitate a smooth transition for the Service
Base customers, the Warranty customers and Buyer following the Closing, Seller
shall transfer to Buyer, and Buyer shall assume responsibility for, the Service
Base and the Warranty Obligations on a gradual basis in accordance with the
schedule set forth on Schedule 2.2. The effective date of transfer hereunder for
each individual Service Contract, Non-Contract Service Right, and Warranty
Obligation shall be the date shown on Schedule 2.2 with respect to such customer
site (the "Effective Date"), which date shall be within 90 days from the Closing
Date as to all customer sites located in the States of New York and Illinois,
and within 45 days from the Closing Date as to all other customer sites. The
period between the Closing Date and the Effective Date of the last Service
Contracts, Non-Contract Service Rights and Warranty Obligations transferred to
Buyer hereunder is referred to as the "Transition Period."

         (b)      Between the Closing Date and the Effective Date for a customer
site, Seller shall continue to provide service to such Service Base and/or
Warranty customer, and shall bill such customer for Seller's own account for any
work performed by Seller during such period in accordance with the underlying
agreement with such customer. Seller shall be entitled to use items of Inventory
as it deems necessary to meet its continuing service obligations during



                                       4
<PAGE>   5

the Transition Period; provided, however, that any item of Inventory so used by
Seller shall be omitted from the Assets, and the Purchase Price shall be
correspondingly reduced pursuant to Section 1.5 above.

         (c)      Within a reasonable time after Closing, Seller shall deliver
the available Inventory to Buyer at Buyer's headquarters in Tulsa, Oklahoma, and
Buyer shall commence testing on such Inventory in accordance with Section
1.1(c). The remainder of the Inventory shall be retained by Seller during the
Transition Period, and Seller shall also be entitled to request from time to
time during the Transition Period that Inventory previously delivered to Buyer
be returned to Seller for use by Seller pursuant to Section 2.2. Within thirty
(30) days following completion of the Transition Period, Seller shall deliver to
Buyer any items of Inventory still in Seller's possession. Buyer shall have
thirty (30) days from receipt of such last shipment of inventory to complete
Buyer's testing of the Inventory.

         (d)      Seller shall be responsible for the arrangement and cost of
all shipping of Inventory, and in all cases, risk of loss shall pass upon
delivery of the Inventory to its destination. Buyer shall contact and coordinate
all shipping with Seller's purchasing and shipping department.

Buyer to comply with its 8-K filing requirements,

         3.8      Contracts and Agreements.

         (a)      All agreements, arrangements, and understandings of any nature

Seller is otherwise bound, regardless of amount or subject matter, that relate
to the Assets or the Business are listed on Schedule 3.8(a) (the "Other

Other Agreements (collectively, for purposes of this Section, the "Agreements").
None of the Agreements have been modified, amended, assigned or transferred and
each of such Agreements is in all material respects in full force and effect and
is a valid and binding Agreement of the parties thereto, enforceable against
them in accordance with its respective terms. No breach or default exists with
respect to any of such Agreements, and no event has occurred which, after the
giving of notice or the passage of time or otherwise, will result in any such
breach or default. There are no counterclaims or offsets under any of the
Agreements. Except with regard to the Service Contracts listed on Schedule
3.8(b), each of such Agreements is freely and fully assignable to Buyer without
the prior written consent of the other party and without penalty or other
adverse consequence.

         (c)      Except as set forth in Schedule 3.8(c), there are no material

the customers under the Service Contracts or the Lease Agreement has been
referred to any outside collection agency for collection of amounts currently
owing under such contracts.

any of the Service Contracts, nor is Seller aware of any customer's intent not
to renew any of the Service Contracts.

         3.9      Compliance with Laws. Seller is in compliance (without
obtaining waivers, variances or extensions) with, and has received no notice of
any violation under, all federal, state and local laws, rules and regulations
which relate to the operations of the Business, except where the failure to be
in compliance would not have a material adverse effect on either the Seller, the
Assets or the Business. All tax and other returns, reports, plans and filings of
any material nature required to be filed by the Seller with any federal, state
or local government authorities (to the extent presently due) have been properly
completed and timely filed in compliance with all applicable requirements,
except where the failure to be so completed or filed would not have a material
adverse effect on the Seller, the Assets or the Business. Each return, report
and filing contains no untrue or misleading statements of a material fact and
does not omit anything which would cause it to be misleading or inaccurate in
any material respect. Further, the Seller has paid all taxes, assessments,
governmental charges, penalties, interest and fines due or claimed to be due
(including, without limitation, taxes on properties, income, franchises,
licenses, sales and payrolls) by any federal, state or local authority. There is
no pending tax examination or audit of, nor any action, suit, investigation or
claim asserted, or to the best knowledge of the Seller threatened, against the
Seller by any federal, state or local tax authority.

         3.10     Absence of Material Changes. Since the date of the balance
sheet included in the Financial Statements, there has not been any material
adverse change in the assets, properties, operations or financial condition of
Seller, which could reasonably be expected to have a material adverse effect
upon the business of Seller, and Seller knows of no development or threatened
development of a nature that will have, or could be reasonably expected to have,
a material adverse effect upon the business of Seller or upon any of its assets,
properties, operations or financial condition.

         3.11     Litigation. There are no suits, actions, claims, proceedings,
inquiries or investigations ("Proceedings") pending or, to the best knowledge of
Seller, threatened against or involving Seller relating to the Assets or the
operation of the Business, except as disclosed on Schedule 3.11.

         3.12     Insurance. Seller maintains with sound and reputable insurers,
and there are currently in full force and effect, policies of insurance with
respect to the Assets and the Business against such casualties and contingencies
of such types and in such amounts as are customary for entities of similar size
engaged in similar lines of business. All premiums due and payable with respect
to such policies have been timely paid. No notice of cancellation of, or
indication of an intention not to renew, any such policy has been received by
Seller.

eliminated from the purchase and sale hereunder pursuant to Section 1.1(c), and
the Leased Equipment are in good condition and are merchantable, suitable and
usable in the ordinary course of the Business for the purposes for which they
are intended.

         3.14     Books and Records. All contracts, billing information,

material respects, have been in all material respects maintained in accordance
with good business practice and all applicable laws, and accurately and fairly
reflect, in reasonable detail, all material transactions, revenues, and accounts
receivable of Seller with respect to the Assets and Business.

         3.15     No Omissions or Misstatements. No material information
included in this Agreement and Schedules or Exhibits hereto, or in any
certificate or other documents furnished or to be furnished by Seller or any of
its representatives pursuant hereto, nor any other written factual material,
spread sheets, e-mail transmissions, correspondence or other communications,
supplied by Seller to Buyer or any of its representatives in connection with the
transactions contemplated by this Agreement, contains any untrue statement of a
material fact or is misleading in any material respect or omits to state any
material fact necessary in order to make any of the statements herein or therein
not misleading in light of the circumstances in which they were made.

         3.16     Brokers. Neither Seller nor any of its affiliates has retained
any financial advisor, broker, agent, or finder or paid or agreed to pay any
financial advisor, broker, agent, or finder on account of this Agreement or any
transaction contemplated hereby.

         3.17     Representations and Warranties on Closing Date. The
representations and warranties made in this Article III will be true and correct
on and as of the Closing Date with the same force and effect as if such
representations and warranties had been made on and as of the Closing Date,
except that any such representations and warranties which expressly relate only

written, to which Buyer is a party or by which any of its assets or properties
may be bound (except for such violations, conflicts, breaches or defaults as to
which required waivers or consents by other parties have been, or will be,
obtained prior to the Closing);

                  (c) result in the creation of any material lien, security
interest, charge or encumbrance upon any of the properties or assets of Buyer;

                  (d) violate any judgment, order, injunction, decree or award
against, or binding upon, Buyer or any of its assets or properties; or

to Buyer.

         4.4      Consents. There are no consents of governmental or other

carry out this Agreement in all material respects.

         4.5      Litigation. There are no Proceedings pending or, to the best
knowledge of Buyer, threatened against or involving Buyer which, if adversely
decided, could have a material adverse effect upon Buyer's ability to execute
and deliver this Agreement and perform its obligations hereunder.

         4.6      No Omissions or Misstatements. No representation, warranty or
statement by Buyer in this Agreement contains any untrue statement of a material
fact or is misleading in



                                       10
<PAGE>   11

any material respect or omits to state any material fact necessary in order to
make any of the statements herein or therein not misleading in light of the
circumstances in which they were made.

         4.7      Brokers. Neither Buyer nor any of its affiliates has retained
any financial advisor, broker, agent, or finder or paid or agreed to pay any
financial advisor, broker, agent, or finder on account of this Agreement or any
transaction contemplated hereby.

         4.8      Representations and Warranties on Closing Date. The
representations and warranties made in this Article IV will be true and correct
on and as of the Closing Date with the same force and effect as if such
representations and warranties had been made on and as of the Closing Date,
except that any such representations and warranties which expressly relate only
to an earlier date shall be true and correct on the Closing Date as of such
earlier date.

         4.9      Financing. Buyer has the cash and other consideration
constituting the Purchase Price immediately available for purchase of the Assets
as contemplated hereby.

         4.10     Inspection. Buyer acknowledges that (i) it has or will have
reviewed such of the contracts, assets, Inventory, and properties comprising or
related to the Assets as Seller has made available to Buyer, to the extent
deemed necessary by the Buyer to determine the condition of the Assets and that
it has, or by the Closing Date will have, fully satisfied itself with respect
thereto, and (ii) it is purchasing the Assets based upon its own examination and
investigation of such contracts, assets, Inventory, and property, and in
reliance upon Seller's representations and warranties as set forth in Article
III hereof.

                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

         5.1      Access to Information. Between the date hereof and the
Closing, Seller shall (i) give Buyer and its authorized representatives
reasonable access to all contracts, and properties of Seller relating to the
Assets (except with regard to the Inventory, which shall be dealt with pursuant
to the provisions of Section 2.2(c) above) or the Business, (ii) permit Buyer
and its authorized representatives to make such inspections as they may
reasonably require, (iii) cause Seller's officers to furnish Buyer and its
authorized representatives with such financial and operating data and other
information with respect to the Assets and the Business as Buyer may from time
to time reasonably request, and (iv) afford Buyer and its counsel, accountants
or other representatives, the opportunity to discuss the operations, affairs and
finances of the Business or related to the Assets, with officers, employees and
representatives of Seller, as Buyer may reasonably request; provided, however,
that such access, review and inspection shall not affect the representations and
warranties made by the Seller hereunder.

         5.2      Endorsement Letters. Seller and Buyer shall co-author and
co-sign letters to be sent to each of the Service Base customers at Closing, by
which Seller shall strongly endorse Buyer as the customer's new service provider
in an unqualified attempt to influence the



                                       11
<PAGE>   12

customer to transfer its loyalty to Buyer. The text of the letters shall be as
set forth in Exhibit "A" attached hereto. At Closing, Seller shall deliver such
individual letters to Buyer, each of which shall be: (i) specifically addressed
to the Service Base customer to the attention of Seller's principal contact for
such customer; (ii) duly signed by Seller; (iii) ready for signature by Buyer;
and (iv) accompanied by a corresponding envelope. Buyer shall be responsible for
mailing such letters.

         5.3      Consents.

         (a)      At Closing, Seller shall sign and deliver to Buyer separate
letters to Hitachi and Centigram, in substantially the same form as Exhibits
"B-1" and "B-2" attached hereto, requesting Hitachi's and Centigram's consent to
the assignment by Seller to Buyer of any outstanding warranties made by such
companies to Seller on the systems underlying the Warranty Obligations to be
assumed by Buyer.

         (b)      Seller shall use all reasonable best efforts to obtain the
consents of any customers required in connection with the transfer to and
assumption of the Service Contracts and Non-Contract Service Rights by Buyer.
Such consents shall be delivered within ninety (90) days of the Closing Date.

         5.4      Noncompetition Agreement. Seller shall execute and deliver to
Buyer at Closing a Noncompetition Agreement in the form set forth as Exhibit "C"
hereto (the "Noncompetition Agreement").

         5.5      Public Announcements. Except as may be required by law in the
opinion of legal counsel to the announcing party, neither Seller nor Buyer shall
issue any press release or otherwise make any public statement with respect to
this Agreement or the transactions contemplated hereby without the prior consent
of the other party, which consent shall not be unreasonably withheld. Any such
press release or other public statement required by law shall only be made after
reasonable notice to the other party.

         5.6      Fees and Expenses. Except as otherwise expressly provided in
this Agreement, all fees and expenses of counsel, accountants and other
advisors, incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such fees or expenses,
whether or not the Closing shall have occurred, except as may otherwise be
specifically provided elsewhere in this Agreement.

         5.7      Survival of Covenants. Except for any covenant or agreement
which by its terms expressly terminates as of a specific date, the covenants and
agreements of the parties hereto contained in this Agreement shall survive the
Closing without contractual limitation.

         5.8      As Is. Except as otherwise specifically set forth in Article
III of this Agreement, Buyer hereby acknowledges and agrees that the Seller
makes no representations or warranties, express or implied, regarding the
acquired Assets, including, without limitation, any representations or
warranties relating to the condition or sufficiency of the acquired Assets



                                       12
<PAGE>   13

or any portion thereof; income to be derived from or expenses to be incurred in
connection with the acquired Assets; the physical condition of any tangible
property comprising any portion of the acquired Assets; the title to or
ownership of the acquired Assets or any portion thereof; the value of the
acquired Assets; the accuracy, completeness, transferability or assignability of
any documents or other materials relating to the acquired Assets (or any portion
thereof); the existence of or rights with respect to any copyrights, trademarks,
trade names or other intellectual property or intangible property rights
relating to or comprising any portion of the acquired Assets (or any portion
thereof) or the transferability of any such rights; the collectibility or
enforceability of any accounts receivable comprising any portion of the acquired
Assets. Accordingly, subject to Article III and without limiting the foregoing,
the Buyer accepts the acquired Assets from the Seller at the Closing "As Is,"
"Where Is" and "With All Faults."

         5.9      Changes and Notifications. Each of the Parties shall notify
the other promptly in writing in the event that it becomes aware that any
representation or warranty made hereunder is untrue in any material respect or
that it is unlikely that any condition to either Party's obligation to
consummate the transactions contemplated by this Agreement will be satisfied by
the Closing Date. In the event that the notifying Party shall have notified the
other Party that any representation or warranty made by such notifying Party is
untrue in any material respect, or any condition to the other Party's
obligations is unlikely to be satisfied, unless such Party elects to terminate
this Agreement in accordance with Section 9.1, such other Party shall be deemed
to have waived any claim that the information specified in the written notice
constitutes a breach of any representation or warranty or that such condition
has not been fulfilled, and such information shall be deemed not to constitute a
breach. Further, if, as a result of the Buyer's inspection made in accordance
with Section 5.1, Buyer determines that there exists a condition that affects
the use or enjoyment of the acquired Assets or breaches a Seller representation
or warranty in Article III, Buyer shall give Seller notice of such condition
promptly after the condition's discovery; provided, however, that no such
notification shall affect the representations and warranties of Seller or the
conditions to the obligations of Buyer unless specifically waived by Buyer in
writing at the Closing. Seller shall have thirty (30) days to remedy such
condition and the Closing shall be postponed, if necessary, to allow for this
cure period. In the event that Seller is unwilling to cure the condition, the
Buyer may accept the Assets by waiving in writing at Closing any right to
recourse against Seller for the identified condition, or terminate this
Agreement. Upon such termination, all funds paid by Buyer to Seller shall be
promptly returned to Buyer and the parties shall no longer be bound hereunder.

         5.10     Non-Solicitation. Buyer agrees not to solicit, offer, promise
employment to, or employ, any sales representative, sales manager or service
personnel employed by Seller during and for a period of six (6) months following
the Closing for any reason, unless written consent is received from Seller. In
the event an employee is hired, Buyer shall promptly pay Seller 25% of the
employee's base salary for expenses associated with replacing and training a new
employee and not as a penalty.

the good faith judgment of Buyer, make it inadvisable for Buyer to proceed with
the consummation of the transactions contemplated hereby.

         7.8      Other Documents. Buyer shall have received the certificates,
instruments, documents and other items listed below:



                                       15

                          SURVIVAL OF REPRESENTATIONS;
                                 INDEMNIFICATION

         8.1      Survival. The representations and warranties of the parties
hereto contained in this Agreement or in any certificate, instrument, or
document delivered pursuant hereto shall survive the Closing, regardless of any
investigation made by or on behalf of any party.

         8.2      Indemnification by Seller. Subject to the terms and conditions
of this Article VIII, Seller shall indemnify, defend, and hold harmless Buyer,
each director, officer, employee, and agent of Buyer, and each affiliate of
Buyer, and their respective heirs, legal representatives, successors, and
assigns (collectively, the "Buyer Group"), from and against any and all claims,
actions, causes of action, demands, assessments, losses, damages, liabilities,
judgments, settlements, penalties, costs, and expenses (including reasonable
attorneys' fees and expenses), of any nature whatsoever, whether actual or
consequential (collectively, "Damages"), asserted against, resulting to, imposed

reason of or resulting from, prior to Closing or within six (6) months after
Closing unless otherwise specifically provided, any of the following:

                  (a) any inaccuracy in or breach of any representation or
         warranty of Seller contained in this Agreement or in any certificate,

                  (b) any breach by Seller of any of its covenants or agreements
         contained in this Agreement or in any certificate, instrument, or
         document delivered pursuant hereto;



                                       16
<PAGE>   17

                  (c) prior to Closing or within one (1) year after Closing, any
         liability or obligation of Seller or its affiliates (whether accrued,
         absolute, contingent, unliquidated, or otherwise, whether or not known
         to Seller, and whether due or to become due), other than the Assumed
         Obligations;

                  (d) the ownership, management, or use of the Assets or the
         Business prior to the Closing Date; or

                  (e) any products or equipment distributed, sold or leased by
         Seller in connection with the Business on or prior to the Closing Date.

Notwithstanding anything herein to the contrary, in no event shall Seller
Group's liability hereunder exceed an amount equal to the Purchase Price, as
adjusted pursuant to Section 1.5.

         8.3      Indemnification by Buyer. Subject to the terms and conditions
of this Article VIII, Buyer shall indemnify, defend, and hold harmless, Seller,
each officer, employee, and agent of Seller, and each affiliate of Seller, and
their respective heirs, legal representatives, successors, and assigns
(collectively, the "Seller Group"), from and against any and all Damages
asserted against, resulting to, imposed upon, or incurred by any member of the
Seller Group, directly or indirectly, by reason of or resulting from any of the
following:

                  (a) any inaccuracy in or breach of any representation or
         warranty of Buyer contained in this Agreement or in any certificate,
         instrument, or document delivered pursuant hereto;

                  (b) any breach by Buyer of any of its covenants or agreements
         contained in this Agreement or in any certificate, instrument, or
         document delivered pursuant hereto;

                  (c) the Assumed Obligations; and

                  (d) the ownership, management, or use by Buyer of the Assets
         from and after the Closing Date, except to the extent Buyer is
         indemnified by Seller with respect to such matters pursuant to Section
         8.2.

Notwithstanding anything herein to the contrary, in no event shall Buyer Group's
liability hereunder exceed an amount equal to the Purchase Price, as adjusted
pursuant to Section 1.5.

         8.4      Defense of Claims. Each party entitled to indemnification
under this Article VIII (the "Indemnified Party") agrees to notify the party
required to provide indemnification (the "Indemnifying Party") with reasonable
promptness of any claim asserted against it in respect of which the Indemnifying
Party may be liable under this Agreement, which notification shall be
accompanied by a written statement setting forth the basis of such claim and the
manner of calculation thereof; provided, however, that the failure to so notify
the



                                       17
<PAGE>   18

Indemnifying Party shall not relieve it of any liability that it may have to the
Indemnified Party except to the extent that the Indemnifying Party demonstrates
that the defense of such action is prejudiced thereby. The Indemnifying Party
shall have the right, at its election, to assume the defense of any such claim
at its own expense with counsel of its choice; provided, however, that (i) such
counsel shall have been approved by the Indemnified Party prior to engagement,
which approval shall not be unreasonably withheld or delayed; (ii) the
Indemnified Party may participate in such defense, if it so chooses with its own
counsel and at its own expense; and (iii) any such defense shall be conducted in
a manner which is reasonable and not contrary to the Indemnified Party's
interest. In the event the Indemnifying Party elects to assume the defense of
such claim, no compromise or settlement thereof may be affected by the
Indemnifying Party without the Indemnified Party's written consent (which shall
not be unreasonably withheld) unless the sole relief provided is monetary
damages that are paid in full by the Indemnifying Party. In the event the
Indemnifying Party does not undertake to defend the claim, the Indemnifying
Party shall promptly notify the Indemnified Party of its intention not to
undertake to defend the claim, and the Indemnified Party shall be entitled to
assume the defense of such claim with counsel of its choice, at the expense of
the Indemnifying Party.

         8.5      Full Cooperation. The parties shall cooperate fully with each
other in connection with any matters covered by the continuing indemnity
obligations under this Agreement. Such cooperation shall include, without
limitation, providing the indemnifying party with reasonable access (charging
only for out-of-pocket expenses) to personnel, files and property and advance
notification of any meetings or communications with any third parties which
could affect the rights or obligations of a party under this Agreement.

         8.6      Claim Limits. Buyer Group and Seller Group shall only be
entitled to indemnification under Section 8 to the extent that the total amount
of the losses suffered by it as a result of misrepresentation or breach by the
other party, exceeds a deductible of $25,000.

                                   ARTICLE IX

                             TERMINATION AND WAIVER

         9.1      Termination. Anything herein or elsewhere to the contrary
notwithstanding, this Agreement may be terminated and the transactions provided
for herein abandoned at any time prior to the Closing:

                  (a) By mutual consent of the Buyer and Seller;

                  (b) By the Buyer if any of the conditions set forth in Article
         VII hereof shall not have been fulfilled on or prior to Closing, or
         shall become incapable of fulfillment, and shall not have been waived;



                                       18
<PAGE>   19

                  (c) By Seller if any of the conditions set forth in Article VI
         hereof shall not have been fulfilled on or prior to Closing, or shall
         have become incapable of fulfillment, and shall not have been waived;
         or

                  (d) By the Buyer or the Seller, if any legal action or
         proceeding shall have been instituted or threatened seeking to
         restrain, prohibit, invalidate or otherwise affect the consummation of
         the transactions contemplated by this Agreement which makes it
         inadvisable, in the judgment of the Buyer or the Seller, to consummate
         same.

In the event that this Agreement is terminated as described above, this
Agreement shall be void and of no force and effect, without any liability or
obligation on the part of any of the parties hereto except for any liability
which may arise pursuant to Sections 5.5, 10.1 and 10.2.

         9.2      Waivers. Any condition to the performance of the Seller or the
Buyer which legally may be waived on or prior to the Closing Date may be waived
at any time by the party entitled to the benefit thereof by action taken or
authorized by an instrument in writing executed by the relevant party or
parties. The failure of any party at any time or times to require performance of
any provision hereof shall in no manner affect the right of such party at a
later time to enforce the same. No waiver by any party of the breach of any
term, covenant, representation or warranty contained in this Agreement as a
condition to such party's obligations hereunder shall release or affect any
liability resulting from such breach, and no waiver of any nature, whether by
conduct or otherwise, in any one or more instances, shall be deemed to be or
construed as a further or continuing waiver of any such condition or of any
breach of any other term, covenant, representation or warranty of this
Agreement.

                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

         10.1     Expenses. Except as otherwise expressly provided or set forth
in, or required by, this Agreement, the Seller and Buyer shall each bear their
own expenses in connection herewith.

         10.2     Confidential Information. Each party agrees that such party
and its representatives will hold in strict confidence and not divulge or
disclose any information and documents received from the other party and, if the
transactions herein contemplated shall not be consummated, each party will
continue to hold such information and documents in strict confidence and will
return to such other parties all such documents (including the schedules and
exhibits attached to this Agreement) then in such receiving party's possession
without retaining copies thereof; provided, however, that each party's
obligations under this Section 10.2 to maintain such confidentiality shall not
apply to any information or documents that are in the public domain at the time
furnished by the other or that come in the public domain thereafter through any
means other than a result of any act or omission of the receiving party or of
its agents, officers, directors or stockholders which constitutes a breach of
this Agreement, or that are required by applicable law to be disclosed. In the
event of a breach or



                                       19
<PAGE>   20

threatened breach under this Section 10.2, the parties to this Agreement

will not have an adequate remedy at law, and shall be entitled to such equitable
and injunctive relief as may be available to restrain the violation of this

party at any time or times to require performance of any provision hereof shall
in no manner affect the right of such party at a later time to enforce the same.
