         2.1 Assumed Liabilities. Subject to the terms and conditions of this
Agreement, on the Closing Date, the Seller shall assign to the Buyer, and the
Buyer shall assume and agree to pay and perform when due, only the specific

                  (a) Notwithstanding the provisions of Section 2.1 above or any
         other provision of this Agreement it is expressly understood and agreed
         by and among the parties hereto that (i) the Buyer shall not assume
         more than $4,500,000 in the aggregate principal amount of Assumed
         Liabilities, and (ii) the Buyer shall not be required to pay more than
         $500,000 in the aggregate principal amount of Assumed Liabilities on or
         before April 30, 1999. 


                  (b) In the event the Buyer is required to pay more than 
         $500,000 in the aggregate principal amount of Assumed Liabilities on 
         or before April 30, 1999, then Buyer, as its sole remedy for any 
         breach under Section 2.2(a)(ii), shall have the right to borrow from 
         AUGI the positive difference of (i) the amount the Buyer is required 
         to pay of the Assumed Liabilities on or before April 30, 1999, less 
         (ii) $500,000. The obligation of AUGI to loan such funds to Buyer 
         shall be conditioned upon a certificate of the Buyer's Chief 
         Financial Officer representing the amount the Buyer is required to 
         pay in cash of the Assumed Liabilities on or before April 30, 1999.

         attached hereto as Exhibit C. Buyer shall have no remedy for a

any debts, liabilities, executory obligations, claims or expenses of the Seller
of any kind, character or description, whether accrued, absolute, contingent or
otherwise, including, without limitation, any liabilities relating to the
Seller's conduct of the Businesses prior to the Closing Date (the "Excluded
Liabilities"). The Seller shall be solely liable and responsible to make timely
payment when due of all such Excluded Liabilities. 

         3. CONSIDERATION.

         3.1 Consideration to the Seller. The entire purchase price for the
Assets (the "Consideration") shall consist of (i) the assumption by the Buyer of
the Assumed Liabilities, and the Buyer's payment and performance, when due, of
all such Assumed Liabilities, subject only to the provisions of Section 2.2 of
this Agreement, and (ii) the rights granted under the Letter Agreement to be
delivered at the Closing in the form annexed hereto as Exhibit E.

         3.2 Allocation of Purchase Price. The fair market values of the Assets
and the allocation of the Purchase Price among the Assets for purposes of
Section 1060 of the Internal Revenue Code shall be as agreed between Buyer and
Seller on or before the Closing Date and included as Schedule 3.2 and Buyer and
Seller agree to be bound by such fair market value determination and allocation
and to complete and attach Internal Revenue Service Form 8594 to their
respective tax returns accordingly. If Buyer and Seller can not agree on the

         4. REPRESENTATIONS AND WARRANTIES OF THE SELLER AND AUGI. In connection
with the sale of the Assets to the Buyer and in order to induce the Buyer to
enter into this Agreement, each of CCC, Connectsoft and AUGI hereby jointly and
severally represents and warrants to the Buyer, as of the date of this Agreement

duly organized, validly existing and in good standing under the laws of the
State of Delaware, Connectsoft is a corporation duly organized, validly existing

of the State of Delaware, each with full corporate power and authority to

contemplated hereby, and to own its assets and conduct its business as owned and
conducted on the date hereof. The Seller is duly qualified to operate its
respective businesses as a foreign corporation under the laws of each
jurisdiction where the nature of its businesses or the location of its
properties makes such qualification necessary and the failure to be so qualified
would have a material adverse effect on the subject Seller or its assets,
properties, businesses or financial condition (a "Material Adverse Effect").

         4.2 Authorization of Agreement. The execution, delivery and performance
of this Agreement and the consummation of the transactions contemplated hereby
by the Seller and AUGI have been duly and validly authorized by the Board of
Directors of the Seller, and by AUGI (as the sole stockholder of each of CCC and
Connectsoft). No further corporate authorization is required on the part of each
Seller or AUGI to consummate the transactions contemplated hereby. 

         4.3 Valid and Binding Agreements. This Agreement, and, when executed,
all other agreements, instruments of transfer or assignment, documents and other
instruments delivered, constitute and will constitute the legal, valid and
binding obligation of the Seller and AUGI (to the extent a party thereto),
enforceable against the Seller and AUGI in accordance with their respective
terms, except to the extent limited by bankruptcy, insolvency, reorganization
and other laws affecting creditors' rights generally, and except that the remedy
of specific performance or similar equitable relief is available only at the
discretion of the court before which enforcement is sought. 

         4.4 Disclosure and Duty of Inquiry. No representation or warranty by
the Seller or AUGI in this Agreement and no statement or information contained
in the schedules hereto or any certificate furnished or to be furnished to the
Buyer hereunder contains or will contain any untrue statement of a material fact
or omits or will omit to state any material fact necessary, in light of the
circumstances under which it was made, in order to make the statements herein or
therein not misleading. The Buyer is not nor will it be required to undertake
any independent investigation to determine the truth, accuracy and completeness
of the representations and warranties made by the Seller and AUGI pursuant to
this Article 4.

         5. ADDITIONAL REPRESENTATIONS AND WARRANTIES OF AUGI AND

<PAGE>


THE SELLER. In connection with the sale of the Assets to the Buyer and in order
to induce the Buyer to enter into this Agreement, each of CCC, Connectsoft and
AUGI hereby jointly and severally represents and warrants to the Buyer, as of
the date of this Agreement (unless otherwise indicated), as follows: 

         5.1 No Breach of Statute or Contract. Neither the execution and
delivery of this Agreement by the Seller, nor compliance with the terms and
provisions of this Agreement, will: (a) violate any statute or regulation of any
governmental authority, domestic or foreign, affecting the Seller, (b) except as
set forth in Schedule 5.1 to this Agreement, require the issuance of any
authorization, license, consent or approval of any federal or state governmental
agency or any other person; or (c) except as set forth in Schedule 5.1 to this
Agreement, conflict with or result in a breach of any of the terms, conditions
or provisions of the certificate of incorporation or by-laws of the Seller or
any judgment, order, injunction, decree, agreement or instrument to which the
Seller is a party, or by which the Seller is bound, or constitute a default
thereunder. 

         5.2 Title to and Condition of Purchased Assets. The Seller owns, or
leases the Assets listed on Schedule 1.1(a) as being leased, and as of the
Closing Date will have good and marketable title in and to, or a valid leasehold
interest in, all of the Assets, free and clear of all liens, liabilities,
charges, claims, options, restrictions on transfer or other encumbrances of any
nature whatsoever, except for (a) liens or encumbrances disclosed in Section 5.2
to this Agreement; and (b) miscellaneous materialmen's or mechanics liens or
liens for current taxes not yet due and payable or which are being contested in
good faith by appropriate proceedings and which are listed on Schedule 5.2
(collectively, "Permitted Liens"). All material items of machinery, equipment,
vehicles, and other personal property owned or leased by the Seller are listed
in Schedule 5.2 to this Agreement and, except as and to the extent disclosed in
Schedule 5.2 to the Agreement, all such personal property is included in the
Assets and is in good operating condition and repair (reasonable wear and tear
excepted) and is adequate for its use in the Seller's Businesses as presently
conducted. The Assets constitute all of the assets and properties which are
required for the Seller's Businesses as presently conducted and as proposed to
be conducted by the Seller as of the date hereof. 


         5.3 Ownership of Businesses. No portion of the Businesses is owned or
operated by any person or entity other than the Seller, except that InterGlobe
operates the CNOC.

         5.4 Form SB-2 Information; Financial Statements. CCC has furnished to
EXTEL a copy of the Form SB-2 Registration Statement of CCC, as filed with the
Securities and Exchange Commission ("SEC") on September 4, 1997 (the
"Registration Statement"), which Registration Statement has not, as yet, been
declared effective by the SEC. On or before the closing of the transactions
contemplated by this Agreement, such Registration Statement shall be withdrawn.
Annexed hereto as Schedule 5.4 is an unaudited balance sheet of CCC as at April
30, 1998 and the unaudited statement of income (loss) of CCC for the nine months
ended April 30, 1998 (collectively, the "April 1998 Financial Statements"). The
April 1998 Financial Statements were prepared by management of CCC, fairly set
forth the assets and liabilities and financial conclusion of CCC and its results
of operations as at April 30, 1998 and for the fiscal period then 

<PAGE>


ended, and were prepared in accordance with generally accepted accounting
principles, consistent with those of prior periods, subject only to the absence
of financial statement footnotes (which would not differ materially from those
of the most recent audited financial statements) and year end audit adjustments
(which would not be material). The financial statements included in the
Registration Statement (a copy of which has been provided to the Buyer) present
fairly, in all material respects, the financial condition of CCC as of July 31,
1997 and the results of operations and cash flows for the respective periods
then ended and have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved. The financial statements referred to in this Section 5.4 do not
reflect the operations of any business or any portion of Seller's Businesses not
included in the Assets. Except as expressly set forth in the April 1998
Financial Statements and those financial statements included in the Registration
Statement, as disclosed pursuant to this Agreement, or non-material liabilities
arising in the normal course of the Seller's Businesses since April 30, 1998,
except for the Assumed Liabilities, there are no liabilities or obligations
(including, without limitation, any tax liabilities or accruals) of the Seller,
including any contingent liabilities, that are, in the aggregate, material to
the Seller. 

         5.5 No Material Changes. Except as otherwise described in Schedule 5.5
to this Agreement, since July 31, 1997, there has been no material adverse
change in the financial condition, operations, or Businesses of the Seller, or
any damage, destruction, or loss (whether or not covered by insurance) of the
Assets materially and adversely affecting the financial condition, operations,
or Businesses of the Seller, provided, that the offering of the Businesses and
the Assets for sale, the preparation for such sale pursuant to the terms and
conditions of this Agreement, and the public disclosure of the same shall not
constitute such a material adverse change. 

         5.6 Insurance Policies. Schedule 5.6 to this Agreement contains a true
and correct schedule of all insurance coverages held by the Seller concerning
the Businesses and the Seller's assets and properties. To the Seller's
knowledge, the Seller is not in violation of any requirements of any its
insurance carriers, and the Seller has received no written notice of any default
or violation under or in respect of any of the foregoing.

         5.7 Permits and Licenses. Except as set forth in Schedule 5.7, the
Seller possesses (and there are included in the Assets being transferred to the
Buyer) all required permits, licenses and/or franchises, from whatever
governmental authorities or agencies (domestic and/or foreign) requiring the
same and having jurisdiction over the Seller, necessary in order to operate the
Businesses in the manner presently conducted, all of which permits, licenses
and/or franchises are valid, current and in full force and effect, except where
the failure to have or maintain any such permit, license and/or franchise would
not have or could not reasonably be expected to have a material adverse effect
on the Assets or the Businesses. The Seller has heretofore conducted the
Businesses in compliance in all material respects with the requirements of such
permits, licenses and/or franchises, and the Seller has not received written
notice of any default or violation in respect of or under any of such permits,
licenses and/or franchises, except where such default would not have or could
not reasonably be expected to have a Material 

<PAGE>

Adverse Effect on the Assets or the Businesses. 

         5.8 Contracts and Commitments. 

         (a) Schedule 5.8 to this Agreement lists all material contracts,
leases, commitments, technology agreements, software development agreements,
software licenses, indentures and other agreements to which the Seller is a
party (collectively, "Material Contracts"), all of which are included in the
Assets except as indicated in Schedule 5.8 except that Schedule 5.8 need not
list any such agreement that is listed on any other schedule hereto, or was
entered into in the ordinary course of the Businesses of the Seller and that, in
any case: (i) is for the purchase of supplies or other inventory items in the
ordinary course of the Businesses; (ii) is related to the purchase or lease of
any capital asset involving aggregate payments of less than $25,000 per annum;
or (iii) may be terminated without penalty, premium or liability by the Seller
on not more than thirty (30) days' prior written notice; provided however, that
Schedule 5.8 shall list all technology agreements, software development
agreements and software licenses involving the Seller and all Assumed
Liabilities, regardless of the duration thereof or the amount of payments called
for or required thereunder, other than standard software licenses of software
products available to the Businesses' customers generally. 


         (b) Except as set forth in Schedule 5.8 to this Agreement, all Material
Contracts are in full force and effect, and the Seller is in compliance in all
material respects with all of the Material Contracts and with all Assumed
Liabilities, and has not received any written notice that any party to any
Material Contract is in material breach or default of such Material Contract or
is now subject to any condition or event which has occurred and which, after
notice or lapse of time or both, would constitute a material default by any
party under any such Material Contract. Except as set forth in Schedule 5.8 to
this Agreement, none of the Material Contracts will be voided, revoked or
terminated, or voidable, revocable or terminable, upon and by reason of the
assignment thereof to the Buyer pursuant to this Agreement. The Seller has
delivered true and correct copies of all Material Contracts to the Buyer. 

         (c) To the best of each Seller's knowledge, no purchase commitment by
the Seller relating to the Businesses is materially in excess of the normal,
ordinary and usual requirements of the Businesses. 

         (d) Except as set forth in Schedule 5.8 to this Agreement, the Seller
does not have any outstanding contracts with or commitments to officers,
employees, technicians, agents, consultants or advisors relating to the
Businesses that are not cancelable by the Seller without penalty, premium or
liability (for severance or otherwise) on less than thirty (30) days' prior
written notice.

         5.9 Customers and Suppliers. Except as set forth in Schedule 5.9 to
this Agreement, the Seller has not received any written notice of any claim by
or dispute with, or any existing, announced or anticipated changes in the
policies of, any material clients, customers, referral sources or suppliers of
the Seller which would have a Material Adverse Effect on the Businesses as 
presently conducted. 

<PAGE>




         5.10 Labor, Benefit and Employment Agreements. 

         (a) Except as set forth in Schedule 5.10 to this Agreement, the Seller
is not a party to and does not have any commitment or obligation in respect of
(i) any collective bargaining agreement or other labor agreement relating to any
employees of the Seller, or (ii) any agreement with respect to the employment or
compensation of any non-hourly and/or non-union employee(s) of the Businesses.
Schedule 5.10 sets forth the amount of all compensation or remuneration
(including any discretionary bonuses) paid by the Seller during the 1997
calendar year to employees or consultants of the Seller who presently receive
aggregate compensation or remuneration at an annual rate in excess of $35,000.

         (b) No union is now certified or, to the best of the Seller's
knowledge, claims to be certified, as a collective bargaining agent to represent
any employees of the Seller, and there are no labor disputes existing or, to the
best of the Seller's knowledge, threatened, involving strikes, slowdowns, work
stoppages, job actions or lockouts of any employees of the Seller. 

         (c) With respect to any "multiemployer plan" (as defined in Section
3(37) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) to which the Seller or any of its past or present affiliates has at
any time been required to make contributions, neither the Seller nor any of its
past or present affiliates has, at any time on or after April 29, 1980, suffered
or caused any "complete withdrawal" or "partial withdrawal" (as such terms are
respectively defined in Sections 4203 and 4205 of ERISA) therefrom on its part.

         (d) Except as disclosed in Schedule 5.10, the Seller does not maintain,
or have any liabilities or Assumed Liabilities of any kind with respect to, any
bonus, deferred compensation, pension, profit sharing, retirement or other such
benefit plan, and does not have any potential or contingent liability in respect
of any actions or transactions relating to any such plan other than to make
contributions thereto if, as and when due in respect of periods subsequent to
the date hereof. Without limitation of the foregoing, (i) the Seller has made
all required contributions to or in respect of any and all such benefit plans,
(ii) no "accumulated funding deficiency" (as defined in Section 412 of the
Internal Revenue Code of 1986, as amended (the "Code")) has been incurred in
respect of any of such benefit plans, and the present value of all vested
accrued benefits thereunder does not, on the date hereof, exceed the assets of
any such plan allocable to the vested accrued benefits thereunder, (iii) there
has been no "prohibited transaction" (as defined in Section 4975 of the Code)
with respect to any such plan, and no transaction which could give rise to any
tax or penalty under Section 4975 of the Code or Section 502 of ERISA, and (iv)
there has been no "reportable event" (within the meaning of Section 4043(b) of
ERISA) with respect to any such plan. All of such plans which constitute, are
intended to constitute, or have been treated by the Seller as "employee pension
benefit plans" or other plans within Section 3 of ERISA have been determined by
the Internal Revenue Service to be "qualified" under Section 401(a) of the Code,
and have been administered and are in compliance with ERISA and the Code; and
the Seller does not have any knowledge of any state of facts, conditions or
occurrences such as would impair the "qualified" status of any of such 

<PAGE>


plans. All of the matters listed on Schedule 5.10 shall constitute Excluded
Liabilities.


         (e) Except for the group insurance programs listed in Schedule 5.10,
the Seller does not maintain any medical, health, life or other employee benefit
insurance programs or any welfare plans (within the meaning of Section 3(1) of
ERISA) for the benefit of any current or former employees, and, except as
required by law, the Seller does not have any liability, fixed or contingent,
for health or medical benefits to any former employee.


         5.11 Accounts Payable. Except as set forth in Schedule 5.11, the Seller
is current in its payment of all accounts payable relating to the Businesses,
and has received no notice, not subsequently withdrawn or cured, from any
vendor, supplier or other person with respect to non-payment or late payment of
any accounts payable of the Businesses, or any threatened suspension or
termination of the provision of goods or services to the Businesses, which
suspension or termination would have a Material Adverse Effect on the financial
condition, operations, or Businesses of the Seller. 

         5.12 Compliance with Laws.
         
         (a) To the Seller's knowledge, the Seller is in compliance in all 
material respects with all laws, statutes, regulations, rules and ordinances 
applicable to the conduct of its Businesses as presently constituted; and the 
Seller has received no written notice of any default or violation under or in 
respect of any of the foregoing.          

         (b) Without limitation of Section 5.12(a) above, except as set forth 
on Schedule 5.12 to this Agreement, to the best of the Seller's knowledge the 
Seller has not, at any time during the three (3) year period prior to the 
date hereof, (i) handled, stored, generated, processed or disposed of any 
hazardous substances in violation of any federal, state or local 
environmental laws or regulations, or (ii) otherwise committed any material 
violation of any federal, state or local environmental laws or regulations 
(including, without limitation, the provisions of the Environmental 
Protection Act, the Comprehensive Environmental Response, Compensation and 
Liability Act, as amended, and other applicable environmental statutes and 
regulations) or any material violation of the Occupational Safety and Health 
Act.

         (c) Except as set forth in Schedule 5.12 to this Agreement, neither the
Seller nor, to the best of the Seller's knowledge, any of the Seller's directors
or officers has received any written notice of default or violation, nor, to the
best of the Seller's knowledge, is the Seller or any of its directors or
officers in default or violation, with respect to any judgment, order, writ,
injunction, decree, demand or assessment issued by any court or any federal,
state, local, municipal or other governmental agency, board, commission, bureau,
instrumentality or department, domestic or foreign, relating to any aspect of
the Seller's Businesses, affairs, properties or assets. Neither the Seller nor,
to the best of the Seller's knowledge, any of its directors or officers, has
received written notice of, been charged with, or is under investigation with
respect to, any violation of any provision of any federal, state, local,
municipal or other law or administrative rule or regulation, domestic or
foreign, relating to any aspect of the Seller's Businesses, affairs, properties
or assets, which violation would have a Material Adverse Effect

<PAGE>


on the financial condition, operations, or Businesses of the Seller or upon any
material portion of the Assets.

         (d) Schedule 5.12 sets forth the date(s) of the last known audits or
inspections (if any) of the Seller conducted by or on behalf of the
Environmental Protection Agency, the Occupational Safety and Health
Administration, the federal Department of Health and Human Services and/or any
agency thereof (including, without limitation, the Health Care Financing
Administration) or intermediary acting on its behalf, any corresponding or
comparable state or local governmental department, agency or authority, and any
other governmental and/or quasi-governmental agency (federal, state and/or
local).

pending, or to the best knowledge of the Seller, threatened, by or against the

All of the matters listed on Schedule 5.13 shall constitute Excluded

or occurrences which might properly constitute grounds for or the basis of any

Assets, which, if adversely determined, would have a Material Adverse Effect on
the financial condition, operations, or Businesses of the Seller or upon any
material portion of the Assets. 


         5.14 Intellectual Property. 

         (a) Schedule 5.14 to this Agreement sets forth a list and brief
description of the nature and ownership of: (i) all patents, patent

officers, stockholders or employees and which in any material way relate to or
are used in the Businesses; (ii) all licenses, both domestic and foreign, which
are owned or controlled by the Seller and/or any of its directors, officers,
stockholders, or employees and which in any material way relate to or are used

arrangements granted to the Seller by others and/or to others by the Seller.
None of the patents, patent applications, copyright registrations or
applications, registered trade names, trademark registrations or applications,

("Third Party Intellectual Rights") which are incorporated in, are or form a
part of any product of the Seller. 


         (c) Schedule 5.14 lists all hardware, computer software, identifiable
know-how (and the manner in which such know-how is memorialized) and other
identifiable technology (collectively, the "Seller Technology") which the Seller
owns or licenses and is included in the Assets, and the nature of the Seller's
rights in each item of Seller Technology. Schedule 5.14 also describes the
technology design and development that is currently ongoing or planned for 1998.


         (d) The Seller owns, or is licensed or otherwise possesses all
necessary rights to use all patents, trademarks, trade names, service marks,
copyrights and any applications therefor, maskworks, net lists, schematics,
technology, know-how, trade secrets, inventory, ideas, algorithms, processes,
computer software programs and applications (in both source code and object code
form), and tangible or intangible proprietary information or material
("Intellectual Property") that are used or marketed in its business as presently
conducted and as proposed to be conducted or included or proposed to be included
in its products or proposed products. 

         (e) To the knowledge of the Seller, there is no unauthorized use,
disclosure, infringement or misappropriation of any Intellectual Property rights
of the Seller, any trade secret material to the Seller or any Intellectual
Property right of any third party to the extent licensed by or through the
Seller by any third party, including any employee or former employee of the
Seller. Except as set forth in Schedule 5.14, the Seller has never entered into
any agreement to indemnify any other person against any charge of infringement
of any Intellectual Property. Except as set forth in Schedule 5.14, there are no
royalties, fees or other payments payable by the Seller to any person by reason
of the ownership, use, sale or disposition of Intellectual Property. 

         (f) The Seller is not, nor will it be as a result of the execution and

Agreement, in material breach of any license, sublicense or other agreement
relating to the Intellectual Property or Third Party Intellectual Property
Rights. 

         (g) The Seller has not (i) been served with process, or is aware that
any person is intending to serve process on the Seller, in any suit, action or
proceeding which involves a claim of infringement of any patents, trademarks,
service marks, copyrights or violation of any trade secret or other proprietary
right of any third party and (ii) brought any action, suit or proceeding for
infringement of Intellectual Property against any third party. To the knowledge
of the Seller, the business of the Seller as presently conducted and as proposed
to be conducted, the Seller's products or proposed products do not infringe any
patent, trademark, service mark, copyright, trade secret or other proprietary
right of any third party.

         (h) The Seller has made available to the Buyer copies of all 

<PAGE>


agreements executed by officers, employees and consultants of the Seller
regarding the protection of proprietary information and the assignment to the
Seller of any Intellectual Property arising from services performed for the
Seller by such persons. 

         (i) The Seller has, to the extent it deemed necessary and appropriate,
obtained or entered into written agreements with third parties in connection
with the disclosure to, or use or appropriation by, third parties, of trade
secret or proprietary Intellectual Property owned by the Seller and not
otherwise protected by a patent, a patent application, copyright, trademark, or
other registration or legal scheme ("Confidential Information"), and does not
know of any situation involving such third party use, disclosure or
appropriation of Confidential Information where the lack of such a written
agreement is likely to result in any material adverse effect on the Seller or
the Assets. 

         5.15 Sensitive Payments. To the best of the Seller's knowledge, the
Seller has not (a) made any contributions, payments or gifts to or for the
private use of any governmental official, employee or agent where either the
payment or the purpose of such contribution, payment or gift is illegal under
the laws of the United States or the jurisdiction in which made, (b) established
or maintained any unrecorded fund or asset for any purpose or made any false or
artificial entries on its or their books, or (c) made any payments to any person
with the intention that any part of such payment was to be used for any purpose
other than that described in the documents supporting the payment. 

         5.16 Real Property. Except as set forth in Schedule 5.16 to this
Agreement, the Seller neither owns or has any interest of any kind (whether
ownership, lease, or otherwise) in any real property except to the extent of the
Seller's leasehold interests under the leases for its Businesses premises, true
and complete copies of which leases (including all amendments thereto) are
annexed to Schedule 5.16 (the "Leases"). The Seller, and to the knowledge of the
Seller, the landlords thereunder, are presently in compliance with all of their
respective Assumed Liabilities under the Leases, and the premises leased
thereunder are in good condition (reasonable wear and tear excepted) and are
adequate for the operation of the Seller's Businesses as presently conducted.

         5.17 Status of Payment Obligations in Respect of Assumed Liabilities.
Schedule 5.17 annexed hereto sets forth the current status of all payment
obligations of the Seller and/or AUGI in respect of each of the Assumed
Liabilities set forth on Schedule 2.1 annexed hereto. 

         5.18 Disclosure and Duty of Inquiry. Sellers have filed all tax returns
required to be filed (except for returns that have been properly extended) and
have paid all taxes shown as owing (other than taxes currently being contested
in good faith by appropriate proceedings, for which amounts have been reserved
in accordance with generally accepted accounting principles ("GAAP")). No tax
returns are currently the subject of audit and there has been no extension of
time for assessment of taxes or waiver of the statute of limitations with
respect to taxes. Neither Seller is party to any tax sharing or allocation
agreement and neither has ever been a member of 

<PAGE>


an affiliated group filing a consolidated federal income tax return. The Buyer
is not nor will it be required to undertake any independent investigation to
determine the truth, accuracy and completeness of the representations and
warranties made by the Seller pursuant to this Article 5.

obligations (including, without limitation, any tax liabilities or accruals) of
either Seller, including any contingent liabilities, that are, in the aggregate,
material to the Businesses or which could have Material Adverse Effect on the
Assets, other than the Assumed Liabilities identified on Schedule 2.1. To the
best of AUGI's knowledge, the amount of each of the Assumed Liabilities is
correctly set forth on Schedule 2.1 in all material respects and, subject to
obtaining an extension of the UPS Note (as herein described), not more than
$500,000 of such Assumed Liabilities will be payable on or before April 30,
1999.

         7.3 Valid and Binding Agreement. This Agreement and, when executed and
delivered, all other agreements, instruments of transfer or assignment,
documents, and other instruments, constitute and will constitute the legal,
valid and binding obligation of EXTEL and the Buyer, enforceable against EXTEL
and the Buyer in accordance with their respective terms, except, in each case,
to the extent limited by bankruptcy, insolvency, reorganization and other laws
affecting creditors' rights generally, and except that the remedy of specific
performance or similar equitable relief is available only at the discretion of
the court before which enforcement is sought. 

         7.4 No Breach of Statute or Contract. Neither the execution and

required to reapply for any permits, licenses and/or franchises which are not
assignable as part of the Assets and any consent of EXTEL's current lenders as
may be required); or (c) conflict with or result in a breach of any of the
terms, conditions or provisions of any judgment, order, injunction, decree,
note, indenture, loan agreement or other agreement or instrument to which EXTEL
or the Buyer is a party, or by which EXTEL or the Buyer is bound, or constitute
a default thereunder. 

         7.5 Disclosure. EXTEL and the Buyer have previously delivered to the

EXTEL Public Filings comply with the SEC disclosure requirements applicable

hereto or any certificate furnished or to be furnished to Seller or AUGI
hereunder contains or will contain any untrue statement of a material fact or
omits or will omit to state any material fact necessary, in light of the

         12. TERMINATION OF AGREEMENT. 

         12.1 General. This Agreement may be terminated and the transactions
contemplated hereby may be abandoned at any time prior to the Closing: (a) by
the mutual written consent of the parties hereto; (b) by EXTEL and the Buyer, on
the one hand, or by the Seller and AUGI, on the other hand, if: (i) a material
breach shall exist with respect to the written representations and warranties
made by the other party or parties, as the case may be, which breach shall not
have been cured within thirty (30) days after notice thereof to such other party
or parties; (ii) the other party or parties, as the case may be, shall take any
action prohibited by this Agreement, if such actions shall or may have a
Material Adverse Effect on the financial condition, operations, or Businesses of
the Seller or on any material portion of the Assets and/or the consummation of
the transactions contemplated hereby, and such breach shall not have been cured,
if the same is capable of cure, within thirty (30) days after notice thereof to
the breaching party, (iii) the other party or parties, as the case may be, shall
not have furnished, upon reasonable notice therefor, such certificates and
documents required in connection with the transactions contemplated hereby and
matters incidental thereto as it or they shall have agreed to furnish, and it is
reasonably unlikely that the other party or parties will be able to furnish such
item(s) prior to the Outside Closing Date specified below, or (iv) any consent
of any third party to the transactions contemplated hereby (whether or not the
necessity of which is disclosed herein or in any schedule hereto) is reasonably
necessary to prevent a default under any outstanding material obligation of
EXTEL, the Buyer, AUGI or the Seller, and such consent is not obtainable, after
good faith efforts to obtain the same, without material cost or penalty (unless
the party or parties not seeking to terminate this Agreement agrees or agree to
pay such cost or penalty); or (c) by EXTEL or the Buyer, on the one hand, or by
the Seller and AUGI, on the other hand, at any time on or after the Outside
Closing Date, if the transactions contemplated hereby shall not have been
consummated prior thereto, and the party directing termination shall not then be
in breach or default of any obligations imposed upon such party by this
Agreement. 

         12.2 Effect of Termination. In the event of termination by either party
as above provided in this Section 12, prompt written notice shall be given to
the other party. Termination of this Agreement shall not relieve any party of
any of its obligations pursuant to Section 9.1 above, and shall not relieve any
breaching party from liability for any breach of this Agreement. 

         13. INDEMNIFICATION. It is expressly understood and agreed by and among
all parties to this Agreement that the indemnification provisions set forth in
this Article 13 are in addition to, and not in lieu of, the respective
indemnification obligations of each of EXTEL and AUGI as are set forth in
Article 14 herein. In the event and to the extent that there shall be any
inconsistency between the rights and obligations contained in this Article 13
and to Article 14, the terms and conditions of Article 14, shall, in all
respects, govern. 

         13.1 General.
<PAGE>

         (a) Without prejudice to any rights of contribution as between the
Seller and AUGI, from and after the Closing Date, the Seller and AUGI shall
jointly and severally defend, indemnify and hold harmless the Buyer and its
stockholders, affiliates, officers, directors, employees and agents (each a
"Buyer Indemnified Person") from, against and in respect of any and all claims,
losses, costs, expenses, obligations, liabilities, damages, recoveries and
deficiencies, including costs of investigation, interest, penalties and
reasonable attorneys' fees, that the Buyer may incur, sustain or suffer
("Losses") as a result of (i) any breach of, or failure by the Seller or AUGI to
perform, in any material respect, any of the representations, warranties,
covenants or agreements of the Seller or AUGI contained in this Agreement, or
(ii) any failure by the Seller to pay or perform when due (or any imposition on
the Buyer or EXTEL) any of its retained liabilities (including any liabilities
of the Business or the Seller which are not Assumed Liabilities). 

         (b) Without prejudice to any rights of contribution as between the
Buyer and EXTEL, from and after the Closing Date, the Buyer and EXTEL shall
jointly and severally defend, indemnify and hold harmless the Seller and AUGI,
and their respective stockholders, affiliates, officers, directors, employees
and agents (each a "Seller Indemnified Person") from, against and in respect of
any and all claims, losses, costs, expenses, obligations, liabilities, damages,
recoveries and deficiencies, including costs of investigation, interest,
penalties and reasonable attorneys' fees, that the Seller or AUGI may incur,
sustain or suffer as a result of (i) any breach of, or failure by the Buyer or
EXTEL to perform, in any material respect, any of the representations,
warranties, covenants or agreements of the Buyer or EXTEL contained in this
Agreement, or (ii) any failure by the Buyer to pay or perform (or any imposition
on the Seller or AUGI) when due any of the Assumed Liabilities. 

         13.2 Limitations on Certain Indemnity. 

         (a) Notwithstanding any other provision of this Agreement to the
contrary, the Seller and AUGI shall not be liable to the Buyer with respect to
Losses unless and until, and then only to the extent that, the aggregate amount
of all Losses incurred by the Buyer shall exceed the sum of $50,000 (the
"Basket"); provided, however, that the Basket shall not be available with
respect to any Losses involving proven fraud by the Seller or AUGI. The Seller
and AUGI shall thereafter be liable for all Losses in excess of the Basket,
provided that the Seller's and AUGI's maximum aggregate liability in respect of
all Losses shall not, in the absence of proven fraud by the Seller or AUGI in
respect of any particular Losses, in any event exceed the limitations set forth
in Section 13.2(b) below. 

         (b) Except with respect to any Losses involving proven fraud by the
Seller or AUGI, the Seller and AUGI shall only be required, in the aggregate, to
pay indemnification hereunder, after application of the Basket, up to a maximum
amount equal to the Consideration.

         (c) The Buyer shall be entitled to indemnification by the Seller and
AUGI for Losses only in respect of claims for which notice of claim shall have
been given to the 

<PAGE>


Seller and AUGI on or before June 30, 1999, or, with respect to Losses relating
to a breach of any warranties in respect of taxes, the expiration of the final
statute of limitations for those tax returns covered by the tax warranties
contained herein; provided, however, that the Buyer shall not be entitled to
indemnification from the Seller or AUGI in the event that the subject claim for
indemnification relates to a third-party claim and the Buyer delayed giving
notice thereof to the Seller and AUGI to such an extent as to cause material
prejudice to the defense of such third-party claim. This Section 13.2(c) shall
not apply to any failure by the Seller to pay when due any of its retained
liabilities. 

         13.3 Claims for Indemnity. Whenever a claim shall arise for which any
party shall be entitled to indemnification hereunder, the indemnified party
shall notify the indemnifying party in writing (which may include facsimile
transmission) within three (3) Business days of the indemnified party's first
receipt of notice of, or the indemnified party's obtaining actual knowledge of,
such claim, and in any event within such shorter period as may be necessary for
the indemnifying party or parties to take appropriate action to resist such
claim. Such notice shall specify all facts known to the indemnified party giving
rise to such indemnity rights and shall estimate (to the extent reasonably
possible) the amount of potential liability arising therefrom. If the
indemnifying party shall be duly notified of such dispute, the parties shall
attempt to settle and compromise the same or may agree to submit the same to
arbitration or, if unable or unwilling to do any of the foregoing, such dispute
shall be settled by appropriate litigation, and any rights of indemnification
established by reason of such settlement, compromise, arbitration or litigation
shall promptly thereafter be paid and satisfied by those indemnifying parties
obligated to make indemnification hereunder. 

         13.4 Right to Defend. If the facts giving rise to any claim for
indemnification shall involve any actual or threatened action or demand by any
third party against the indemnified party or any of its Affiliates, the
indemnifying party or parties shall be entitled (without prejudice to the
indemnified party's right to participate at its own expense through counsel of
its own choosing), at their expense and through counsel of their own choosing,
to defend or prosecute such claim in the name of the indemnifying party or
parties, or any of them, or if necessary, in the name of the indemnified party.
In any event, the indemnified party shall give the indemnifying party advance
written notice of any proposed compromise or settlement of any such claim. If
the remedy sought in any such action or demand is solely money damages, the
indemnifying party shall have five (5) Business Days after receipt of such
notice of settlement to object to the proposed compromise or settlement, and if
it does so object, the indemnifying party shall be required to undertake,
conduct and control, though counsel of its own choosing and at its sole expense,
the settlement or defense thereof, and the indemnified party shall cooperate
with the indemnifying party in connection therewith.

and 14.2. 

         14.2 Indemnification of the Buyer and EXTEL. Each of AUGI, Connectsoft
and CCC does hereby jointly and severally, irrevocably, absolutely and
unconditionally indemnify, defend and holds harmless the Buyer and EXTEL, and
each of them, individually and severally, to the fullest extent permitted by
law, from and against any claim against the Buyer or EXTEL in respect of (i) any
act, omission, neglect, breach or failure by AUGI, Connectsoft and/or CCC, or
any of them, to timely and fully pay and perform (a) each and every one of the
Excluded Liabilities, when due, and (b) any of the Assumed Liabilities, but only
to the extent that the aggregate principal amount of all such Assumed
Liabilities shall exceed $4,500,000 and (ii) as a result of, arising from or in
connection with any claim by any taxing authority for Taxes of or relating to

estimated taxes, withholding taxes, excise taxes, sales taxes, use taxes, gross
receipt taxes, franchise taxes, employment and payroll related taxes, property
taxes and import duties, whether or not measured in whole or in part by net
income, and all deficiencies or other additions to tax, interest and penalties
owed by it in connection with any such taxes. Each of AUGI, Connectsoft and CCC
jointly and severally covenants and agrees to fully pay and reimburse each of
the Buyer and EXTEL, within twenty-four (24) hours of written demand therefor,
for any payments made or amounts which the Buyer or EXTEL becomes legally
obligated to pay in connection with any of the EXTEL Group Indemnified Amount.

         14.3 Claims for Indemnity. Whenever a claim shall arise for which any
party shall be entitled to indemnification hereunder, the indemnified party
shall promptly notify the indemnifying party in writing (which may include
facsimile transmission) following the indemnified party's receipt of notice of,
or the indemnified party's obtaining actual knowledge of, such claim. Such
notice shall specify all facts known to the indemnified party giving rise to
such indemnity rights and shall estimate (to the extent reasonably possible) the
amount of potential liability arising therefrom.

         14.4 Right to Defend. If the facts giving rise to any claim for
indemnification 

<PAGE>


shall involve any actual or threatened action or demand by any third party
against the indemnified party or any of its affiliates, the indemnifying party
or parties shall be entitled (without prejudice to the indemnified party's right
to participate at its own expense through counsel of its own choosing), at their
expense and through counsel of their own choosing, to defend or prosecute such
claim in the name of the indemnifying party or parties, or any of them, or if
necessary, in the name of the indemnified party. In any event, the indemnified
party shall give the indemnifying party advance written notice of any proposed
compromise or settlement of any such claim. If the remedy sought in any such
action or demand is solely money damages, the indemnifying party shall have
three (3) days after receipt of such notice of settlement to object to the
proposed compromise or settlement, and if it does so object, the indemnifying
party shall be required to undertake, conduct and control, though counsel of its
own choosing and at its sole expense, the settlement or defense thereof, and the
indemnified party shall cooperate with the indemnifying party in connection
therewith.

Businesses, to those books and records transferred to the Buyer as part of the
Assets, for purposes of preparing any tax filings or any other legitimate
purpose of the Seller and/or AUGI. Such books and records may be made available

and records, the Buyer shall give notice thereof to the Seller and/or AUGI not
less than thirty (30) days prior to such disposition, and the Seller and/or AUGI
