Item 2.   Acquisition or Disposition of Assets

     On June 26, 1998, Analytical Surveys, Inc. (the "Company") acquired all 
of the outstanding stock of Cartotech, Inc. ("Cartotech"), a Texas 
corporation, 11900 Crownpoint Drive, San Antonio, Texas from The Epner Family 
Limited Partnership (the "Epner Partnership"), The Braverman Family Limited 
Partnership (the "Braverman Partnership"), The Cartotech, Inc. Employee Stock 
Ownership and 401(k) Trust (the "ESOP") and Albert Naumann, III (collectively 
referred to as the "Shareholders"), who constitute all of the shareholders of 
Cartotech.  The transaction was consummated via a merger (the "Merger") of 
Cartotech with and into Surveys Holdings, Inc. ("Holdings"), a Texas 
corporation, and a wholly-owned subsidiary of the Company.  Cartotech is 
engaged in the business of data conversion, digital mapping and database 
construction in the geographic information systems industry.

     Consideration paid for Cartotech consisted of a net amount of cash of 
approximately $7,700,000 and 354,167 restricted shares of Analytical Surveys, 
Inc. no par value common stock (the "Common Stock").  The number of shares of 
Common Stock issued was determined in part by the average closing price of 
the Common Stock over the ten trading days before and after June 12, 1998, 
the day after the transaction was publicly announced.  The Common Stock is 
subject to contractual restrictions on sale or transfer and a  registration 
rights agreement.  The ESOP has agreed not to sell any of the Common Stock it 
receives for one year.  The Epner Partnership, the Braverman Partnership and 
Albert Naumann, III (collectively referred to as the "Non-ESOP Shareholders") 
have agreed not to sell any of the Common Stock received in the Merger for 
one year; between June 27, 1999 and June 26, 2000, inclusive, each of the 
Non-ESOP Shareholders may transfer up to one-half of the Common Stock 
received in the Merger.  The Shareholders also have certain additional 
incidental registration rights beginning after June 26, 1999.  The 
Shareholders have granted to the Company an option to purchase at the market 
price, in lieu of registration, any shares that they subject to an incidental 
registration.  A Non-ESOP Shareholder is allowed to make transfers to a trust 
or other entity created for the exclusive benefit of, or beneficially owned 
exclusively by, such Non-ESOP Shareholder at any time, but any transferee is 
subject to the same restrictions as apply to such Non-ESOP Shareholder.

     Prior to the Merger, there was no material relationship between the 
Company or any of its affiliates, officers or directors and Cartotech or any 
of its affiliates, officers or directors.  Martin Epner, who served as 
President of Cartotech and who controls the Epner Partnership, will serve the 
Company in a consulting capacity under an 18-month agreement, and Albert 
Naumann III will serve as president of the subsidiary under a 2-year 
employment agreement.

     On June 3, 1998, the Company replaced its existing lines of credit with 
a 3-year, $11.0 million secured line of credit and a $10.0 million line of 
credit for acquisitions (which is due in quarterly installments over a 
five-year period), and the Company refinanced $16.0 million of term debt.   
The lender under the new credit facilities is Bank One, Colorado, N.A.  
Borrowings under the new credit facilities bear interest at a rate per annum 
equal to, at the Company's option, (i) the bank's prime rate, or (ii) an 
adjusted London Interbank Offered Rate ("LIBOR") plus a margin ranging from 
1.25% to 2.25%.  The Company borrowed approximately $8.3 million under the 
new acquisition line of credit to fund the cash portion of the acquisition of 
Cartotech and related expenses.

<PAGE>

     The Common Stock was newly issued from the previously authorized but 
unissued shares of the Company. 

     The assets of the business acquired included contracts with customers 
and equipment used in Cartotech's data conversion business.  The Company 
intends to continue to operate the business in  substantially the same 
general manner and in the same location.

                                  ARTICLE II.
                                   THE MERGER

     2.1    THE MERGER.  At the Effective Date, the Company will be merged 
with and into Holdings on the terms and conditions set forth below as 
permitted by and in accordance with the Texas Business Corporation Act.  Upon 
the Effective Date, the separate existence of the Company will cease; 
Holdings, as the Surviving Corporation, will continue to exist under and be 
governed by the Texas Business Corporation Act; and the articles of 
incorporation and bylaws in the form attached to this Agreement as EXHIBIT 
2.1 will become the articles of incorporation and bylaws of Holdings until 
further amended in accordance with the provisions of such articles and bylaws 
and applicable law.

     2.2    ARTICLES OF MERGER.  On the Closing Date, the Company and 
Holdings will cause the Articles of Merger in the form of EXHIBIT 2.2 
attached to this Agreement (the "Articles of Merger") to be executed and 
filed with the Secretary of State of the State of Texas as provided in the 
Texas Business Corporation Act.  The purpose of the Surviving Corporation 
will be to engage in any and all business activities in which a corporation 
is permitted to engage in accordance with the Texas Business Corporation Act.

immediately upon the filing of the Articles of Merger with the Secretary of 
State of the State of Texas or on such other date thereafter as the parties 
may agree.  The date and time of such effectiveness is sometimes referred to

the Merger be treated as a tax-free "reorganization" under Section 
368(a)(1)(A) and (a)(2)(D) of the Internal Revenue Code of 1986, as amended 
(the "Code"). The parties agree to report 

                                       9
<PAGE>

the transaction in such manner.

     2.5    DIRECTORS AND OFFICERS.

            (a)    From and after the Effective Date, the members of the 
Board of Directors of the Surviving Corporation will consist of the members 
of the Board of Directors of Holdings (as constituted immediately prior to 
the Effective Date) until changed in accordance with the articles of 
incorporation and bylaws of the Surviving Corporation and applicable law.

            (b)    From and after the Effective Date, the officers of the 
Surviving Corporation will consist of the officers of Holdings (as 
constituted immediately prior to the Effective Date) until changed in 
accordance with the articles of incorporation and bylaws of the Surviving 
Corporation and applicable law.

     2.6    CONVERSION.

            (a)    At Closing, each Share will, without any further action on 
the part of ASI or Holdings, on the one hand, or the Company or any of the 
Shareholders, on the other hand, be converted into the right to receive 
directly from ASI the following:

                   (i)    $51.33 in cash, plus based on $7,700,000, plus the
                          cash paid for the Conic Transaction under Section
                          2.10, less the cash needed to fund the payments to
                          the Option Holders under (b), which sum is to be
                          divided by 157,096, which is to be the number of
                          outstanding Shares as of the Effective Date, plus

                   (ii)   shares of Common Stock based on the following
                          formula:

                   R =     $10,625,000      DIVIDED BY N
                           -----------
                                A

                   Where

                   A = the ASI Share Value, except that, "A" will be $20 if
                   the ASI Share                      Value is less than $20,
                   and "A" will be $30 if the ASI Share Value is greater than
                   $30.

                   N = the number of outstanding shares, and

                   R = the number of shares of Common Stock to be issued per

                                       10
<PAGE>

              Share,

              such that no more than an aggregate of 531,250 shares of Common
              Stock will be issued and no fewer than an aggregate of 354,167
              shares of Common Stock will be issued.

[ASI may pay $1,000,000 of the cash consideration one Business Day after the
Closing Date.]

              (b)    At Closing, each Option Holder will be entitled to 
receive in cash from ASI an amount equal to $46.43 per Share covered by an 
option, except for the options held by John Federowicz, for which the payment 
will be $21.71 per Share, for a total payment of $636,155, except that ASI 
will deposit 7.4% of such cash as Escrowed Property under the Escrow 
Agreement.

              (c)    The Common Stock and cash comprising the Escrowed 
Property (as defined in the Escrow Agreement) will be subtracted from the 
Common Stock issued and the cash paid to the Shareholders at Closing and will 
be deposited into the Escrow Account (as defined in the Escrow Agreement).  
Out of the cash consideration paid to the ESOP pursuant to this Agreement 
with respect to the Unallocated Shares in the ESOP (after reduction by reason 
of the foregoing transfer to the Escrow Account), an amount will be paid in 
cash to the Surviving Corporation sufficient to fully retire the 
ESOP-to-Company Debt.

              (d)    All cash payments at Closing that are payable directly 
to Shareholders or Option Holders will be made by wire transfer of 
immediately available funds to the accounts designated by the Shareholders' 
Agent.

              (e)    The parties desire that the value of the Common Stock be 
at least 45% of the total consideration being paid to the Shareholders under 
the Merger, based on the closing price of the Common Stock on Nasdaq as of 
the Business Day prior to the Closing Date, discounted by 30%. Accordingly, 
if the 45% level would not be satisfied, the parties agree that the amount of 
cash payable to the Shareholders under Section 2.6(a)(i) will be decreased, 
and the number of shares of Common Stock issuable to the Shareholders under 
Section 2.6(a)(ii) will be increased until the 45% level is satisfied. The 
parties agree that the total consideration for the Shareholders, calculated 
as the sum of (i) cash plus (ii) the product of shares of Common Stock 
multiplied by the closing price of the Common Stock on Nasdaq as of the 
Business Day prior to the Closing Date, discounted by 30%, will not change as 
the result of any adjustments made in accordance with this Section 2.6(e).

                                       11
<PAGE>

     2.7    NO FRACTIONAL SHARES.  No certificate or scrip representing 
fractional shares of Common Stock will be issued to the Shareholders upon 
conversion of the Shares pursuant to the Merger, and no dividend, stock split 
or interest will relate to any such fractional shares.  In lieu of any 
fractional share of Common Stock being issued, cash will be paid to or the 
Shareholders in respect of such fractional share based on the ASI Share Value.

     2.8    CLOSING DATE BALANCE SHEET.  Within 30 days after the end of the 
month during which the Effective Date occurs, the Shareholders will deliver 
to ASI at the Shareholders' expense an internally prepared, unaudited 
consolidated balance sheet for the Company as of the end of the month during 
which the Effective Date occurs.  The Shareholders will also deliver a 
schedule reconciling the shareholders' equity accounts ("Reconciliation 
Schedule") by determining the pre-tax earnings (or loss) of the Company 
during the month in which the Effective Date occurs, pro rating such pre-tax 
earnings (or loss) over the Business Days during such month through the 
Effective Date, and using on such Reconciliation Schedule such pro rated 
pre-tax earnings (or loss) instead of the actual pre-tax earnings (or loss) 
for the partial month ended on the Effective Date, and then giving effect to 
the estimated income taxes on any such earnings.  (Such balance sheet, 
together with the Reconciliation Schedule, are referred to as the "Closing 
Date Balance Sheet").  Except as provided in the immediately preceding 
sentence, the Closing Date Balance Sheet will be prepared in accordance with 
GAAP on a basis consistent with the accounting policies applied by the 
Company for the December 31, 1997 audited Financial Statements of the 
Company.  The Closing Date Balance Sheet will reflect the estimated amount of 
any excise tax that may become payable by the Company or Surviving 
Corporation which is attributable to the disposition of Shares or Common 
Stock in connection with the Merger or the subsequent disposition of Common 
Stock by the ESOP, as set forth in Section 4.1(g)(vi), the amount of any 
unpaid fees and expenses by the Company or the ESOP to their respective 
counsel or accountants (but only $7,500, which is one-half of the fee of 
Sherman & Howard L.L.C. for the rendering of its tax opinion concerning the 
Merger), the amount of any unpaid fees and expenses payable to the Seller's 
Broker, unpaid appraisal fees for the Conic stock, $23,365.35 (which is the 
amount agreed to be borne by the Shareholders to compensate ASI with respect 
to certain obligations under the employment agreement for Dan DeCourcy), the 
amount payable to Martin Epner under the SERP, and any other expenses of the 
Company incurred in connection with the Merger (other than the buyout of the 
options under the Option Buy Out Agreements).

     2.9    ADJUSTMENTS; PROCEDURE.  Following delivery of the Closing Date 
Balance Sheet in accordance with Section 2.8, certain procedures will apply 
and adjustments to the amounts payable under Section 2.6 will be made in 
accordance with the Pro Rata Shares of the Shareholders and the Option 
Holders, as follows:

                                       12
<PAGE>

            (a)    ASI will examine the Closing Date Balance Sheet to 
determine whether it believes the Closing Date Balance Sheet was prepared in 
accordance with the provisions of this Agreement.  In connection with that 
examination, the Shareholders will provide, and will cause the Company's 
accountants to provide, ASI and ASI's accountants with access to such 
information as ASI may reasonably request to make that determination, 
including access to all work papers and calculations of the Company related 
to the preparation of the Closing Date Balance Sheet.

            (b)    Within 10 days after receipt of the Closing Date Balance 
Sheet, ASI will, in a written notice to the Shareholders' Agent, either 
accept the Closing Date Balance Sheet or object to it by describing in 
reasonable detail any proposed adjustments to the Closing Date Balance Sheet 
and the reasons for such proposals.  If the Shareholders' Agent has not 
received such notice of proposed adjustments within such 10-day period, ASI 
will be deemed to have accepted the Closing Date Balance Sheet, but if ASI's 
failure to give such notice results from the Shareholders' failure to timely 
provide information requested by ASI under Section 2.9(a) and if ASI has so 
informed the Shareholders' Agent of such failure during such 10-day period, 
the time within which ASI must give such notice will be extended until a 
reasonable time after the Shareholders provide the information requested by 
ASI.

            (c)    If any adjustments to the Closing Date Balance Sheet are 
proposed, ASI and the Shareholders' Agent will negotiate in good faith to 
resolve any dispute, but if the dispute is not resolved within 10 days 
following the Shareholders' Agent's receipt of the proposed adjustments, ASI 
and the Shareholders' Agent will retain a mutually acceptable nationally 
recognized independent public accounting firm to resolve such dispute, which 
resolution will be final and binding.  The fees and expenses of any such 
accounting firm will be shared equally by ASI and the Shareholders and such 
accounting firm will be retained by a retention letter executed by the 
parties that specifies that the determination by said firm of any such 
disputes concerning the Closing Date Balance Sheet will be resolved in 
accordance with GAAP on a basis consistent with the accounting policies 
applied by the Company in its December 31, 1997 audited Financial Statements. 
 If ASI and the Shareholders' Agent are unable to agree on a mutually 
acceptable independent public accounting firm to resolve such dispute, the 
dispute will be resolved by arbitration in accordance with Section 10.2.

            (d)    On the Adjustment Date (if no dispute occurs), or within 
10 business days after the resolution of a dispute (if a dispute occurs and 
is to be resolved in accordance with Section 2.9(c)), as the case may be, 
then to the extent that the Adjusted Net Worth of the Company as set forth on 
the Closing Date Balance Sheet is less than $2,550,000 (before giving effect 
to the Conic Transaction, but after giving 

                                       13
<PAGE>

effect to all of the other adjustments described in the last sentence of 
Section 2.8, including the tax payable in connection with the Conic 
Transaction), the Shareholders and the Option Holders will pay to ASI the 
difference between such two amounts (the "Closing Date Deficit"), except that 
an amount equal the lesser of the Closing Date Deficit and the estimated 
excise tax described in Section 4.1(g)(vi) (the "Epner Surcharge") will be 
payable solely by the Epner Partnership out of its share of the Escrow 
Account. Except as provided with respect to an Epner Surcharge, any Closing 
Date Deficit will be taken from the cash in the Escrow Account based on the 
Pro Rata Shares of the Shareholders and the Option Holders.  If the cash in 
the Escrow Account that is attributable to the Shareholders is insufficient 
to pay the Closing Date Deficit, then the Pro Rata Share of the Shareholders 
will be taken from the Escrow in the form of Common Stock based on the 
Credited Value of the escrowed Common Stock, determined as of the date that 
the amount of the claim against the Escrow Account is determined.  If any 
amounts are taken from the Epner Partnership's share of the Escrow Account as 
the result of an Epner Surcharge, and if, as a result, insufficient proceeds 
remain in the Escrow Account that are attributable to the Epner Partnership 
to cover any Closing Date Deficit or any other claim against the Escrow 
Account, then the Epner Partnership will be required, within 10 days after 
demand by ASI or any Shareholder, to replenish the Escrow Account with cash 
(up to the amount of the Epner Surcharge) sufficient to cause the Epner 
Partnership to bear its share of the liability. Any payments due under this 
Section 2.9(d) will include interest accrued from the Closing Date to the 
date of such payment at the Prime Rate.

     2.10   CONIC TRANSACTION.  Immediately prior to the consummation of the 
Merger, (a) the Non-ESOP Shareholders will pay to the Company cash in the 
aggregate amount of $1,000,000 and (b) the Company will transfer to the 
Non-ESOP Shareholders all of the common stock of Conic, Inc. held by the 
Company and will execute and deliver to the Non-ESOP Shareholders a bill of 
sale in the form of EXHIBIT 2.10(b).

                                 ARTICLE III.
                              SHAREHOLDERS' AGENT

     3.1    AGENT FOR SHAREHOLDERS.  The Shareholders designate Martin Epner 
(the "Shareholders' Agent") as agent to act for and on behalf of all of the 
Shareholders with respect to actions to be taken by any of the Shareholders 
under the terms of this Agreement.  Specifically, each Shareholder hereby 
authorizes and irrevocably appoints the Shareholders' Agent as its or his 
exclusive agent and attorney-in-fact to act on behalf of each of them (a) to 
amend, without notice to or consent of any Shareholder, the provisions of 
this Agreement or any Other ASI Agreement or Other Shareholder Agreement (i) 
to the extent such amendment does not, in the opinion of the Shareholders' 
Agent, materially adversely affect the rights of any Shareholder or (ii) to 
cure any ambiguity, defect or inconsistency in any such agreement and (b) 
with respect 

                                       14

<PAGE>

to all matters which are the subject of this Agreement or the Escrow 
Agreement, to exercise any and all powers, authority and discretion conferred 
upon the Shareholders (other than matters for which the Shareholders do not 
have joint and several liability), including, without limitation, (i) 
receiving or giving all notices, instructions, other communications, consents 
or agreements that may be necessary, required or given with respect to such 
matters; (ii) asserting, settling, compromising, or defending, or determining 
not to assert, settle, compromise or defend, any claims which any Shareholder 
may assert, or have the right to assert, against ASI, or any claims which ASI 
may assert, or have the right to assert, against any Shareholder; (iii) 
receiving and distributing the Common Stock and cash after the conversion 
provided for in Section 2.6; and (iv) making such changes or modifications to 
the schedules and this Agreement as it determines are reasonably necessary to 
facilitate consummation of the transactions contemplated under this 
Agreement.  The Shareholders' Agent accepts such authorization and 
appointment.  ASI and Holdings will have the right to deal with the 
Shareholders' Agent exclusively and will be entitled to rely conclusively on 
the Shareholders' Agent's determination or action.  If the Shareholders' 
Agent resigns, dies or becomes disabled, the remaining Shareholders hereby 
appoint Albert Naumann III as substitute agent for the Shareholders for all 
purposes under this Agreement as if such Person was the original 
Shareholders' Agent.  Upon the receipt of written evidence satisfactory to 
ASI to the effect that the Shareholders' Agent has been substituted as agent 
of the Shareholders by reason of his death, disability or resignation, ASI 
and Holdings will be entitled to rely on such substituted agent to the same 
extent as they were theretofore entitled to rely upon the Shareholders' Agent 
with respect to the matters covered by this Section.  No Shareholder will act 
with respect to any of the matters which are the subject of this Agreement 
(other than matters for which the Shareholders do not have joint and several 
liability, as listed in Section 9.7) except through the Shareholders' Agent.  
The Shareholders acknowledge and agree that ASI and Holdings may deal 
exclusively with the Shareholders' Agent in respect of such matters.  Neither 
the Shareholders' Agent nor any of his or its employees or agents will be 
liable to the Shareholders for any action taken or omitted to be taken or 
suffered in good faith by it under or in connection with this Agreement, 
except that the Shareholders' Agent will be liable for his willful 
misconduct.  The Shareholders' Agent will be responsible for performing the 
tasks specifically designated under this Agreement, but the Shareholders' 
Agent, in its capacity as such, will not be liable to the Company, Holdings, 
ASI, or the other Shareholders in any manner for the effectiveness, 
enforceability, collectibility, genuineness, perfection, validity, 
sufficiency or the due execution of this Agreement, the Escrow Agreement or 
any of the Other ASI Agreements or Other Shareholder Agreements, or for the 
due authorization, authenticity or accuracy of the representations and 
warranties in this Agreement or in any other certificate, report, notice, 
consent, opinion, statement, or other document furnished or to be furnished 
under this Agreement, and the Shareholders' Agent will be entitled to rely 
upon any of the foregoing believed by it to be genuine and correct and to 

                                       15
<PAGE>

have been signed and sent or made by the proper Person.  This power of 
attorney is coupled with an interest and is irrevocable.  Each Shareholder 
acknowledges that he or it has made such investigation as such Shareholder 
deems necessary to inform himself or itself of the affairs of ASI and 
Holdings and has made his or its own investigation of the operations and 
affairs of ASI and Holdings and that in entering into this Agreement he or it 
has not relied and will not rely upon any information or representations 
furnished or given by the Shareholders' Agent.

                                  ARTICLE IV.
                         REPRESENTATIONS AND WARRANTIES

     4.1    REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERs.  The 
Shareholders jointly and severally represent and warrant to ASI and Holdings 
as follows, as of the date of this Agreement:

            (a)    ORGANIZATION, GOOD STANDING, ETC.  The Company is a 
corporation duly organized, validly existing and in good standing under the 
laws of the State of Texas, and is qualified to do business as a foreign 
corporation and is in good standing in Rhode Island, Mississippi, 
Massachusetts, Delaware, Maryland, New Jersey, Connecticut, Florida, Arkansas 
and California which are the only jurisdictions in which such qualification 
is necessary and in which the failure to be so qualified would have a 
material adverse effect on the business or properties of the Company (and 
also is qualified to do business and in good standing in Pennsylvania,

Tax Returns that it was required to file, except for the 1997 federal 
corporate income tax return of the Company, and the 1997 Texas franchise tax 
return, as to which extensions until September 15, 1998, were obtained.  The 
amount of Income Taxes paid by the Company when the Company applied for an 
extension for the filing of its 1997 federal corporate income tax return 
equals or exceeds the amount of federal corporate income tax payable by the 
Company with respect to 1997, except that the payment made in connection with 
the extension was late but the Company has incurred no penalty or interest 
obligations with respect to such late return, and no amounts are payable in 
connection with the 1997 Texas franchise tax return. All such Income Tax 
Returns and all other Tax Returns were correct and complete in all material 
respects. All Income Taxes and all other Taxes owed by the Company (whether 
or not shown on any Tax Return) have been paid.  The Company is currently the 
beneficiary of any extension of time within which to file any Tax Return.  No 
claim has ever been made by an authority in a jurisdiction where the Company 
does not file Tax Returns that it is or may be subject to taxation by that 
jurisdiction.  There are no Encumbrances on any of the assets of the Company 
that arose in connection with any failure (or alleged failure) to pay any Tax.

                     (ii)   The Company withheld and paid all Taxes required to
have been withheld and paid in connection with amounts paid or owing to any
employee, independent contractor, creditor, any Shareholder or other third
party.

                     (iii)  There is no pending or threatened dispute or claim
concerning any Tax liability of the Company.  SCHEDULE 4.1(g)(iii) lists all
federal, state, local and foreign income Tax Returns filed with respect to the
Company for taxable periods ended on or after December 31, 1994, identifies
those Tax Returns that have been audited and identifies those Tax Returns that

and complete copies of all federal income Tax Returns and Texas corporate
franchise Tax Returns, and all examination reports, and statements of
deficiencies filed or assessed against or agreed to by the Company since
December 31, 1994.

limitations in respect of Taxes or agreed to any extension of time with respect
to a Tax assessment or deficiency.

ever filed a consent pursuant to Section 341(f) of the Code relating to
collapsible corporations.  The Company has not made any payments, is not
obligated to make any payments and is not a party to any agreement that under
certain circumstances could obligate it to make any payments that will not be
deductible under Code Section 280G.  The Company has not been a United States
real property holding corporation within the 


                                      21

income Tax Return (other than a group the common parent of which was the 
Company) and have no liability for the Taxes of any Person (other than the 
Company) under Treasury Regulation Section 1.1502-6 (or any similar provision 
of state, local, or foreign law), as a transferee or successor, by contract 
or otherwise. 

                     (vi)   Upon the consummation of the Merger and 
disposition of the Common Stock by the ESOP, the Surviving Corporation will 
be required to pay an excise tax occasioned by the disposition of the Shares 
owned by the ESOP. The excise tax will be in the maximum amount of 10% of 
2.1% of the value of all of the Shares as of the date of Closing, will be an 
obligation of the Surviving Corporation, and will be reflected as a liability 
in the Closing Date Balance Sheet.

Company has good title to (or, in the case of the assets that are leased,

its business, free and clear of all Encumbrances (except for Permitted 
Encumbrances).  Such assets consist of the tangible and intangible assets of 
the Company in existence as of the Closing Date.  Such assets are all of the 
tangible and intangible assets used by the Company in its business as 
conducted by the Company since January 1, 1998.  Such assets and any 
equipment leased by the Company from third parties encompass all equipment 
used by the Company to generate the income reflected in the financial 
statements attached as SCHEDULE 4.1(e)(i).  SCHEDULE 4.1(h)(i) lists all the 
third party equipment leased by the Company as of the date of this Agreement.

under any such policy; no insurer under any such insurance policy has denied
coverage or reserved against coverage concerning any claim made by the Company;
and, to the best knowledge of the Shareholders, no event exists which, with the
giving of notice or the lapse of time or both, would constitute a breach,
default or event of default, or permit termination, modification or acceleration
under any such policy.  All premiums which are due on such policies as of the
date of this Agreement have been paid on such policies as of the date of this
Agreement. All claims made during such five-year period with respect to any
insurance coverage of the Company, other than claims made by or on behalf of
employees of the Company or under the Company's health insurance policy and
other than those described on SCHEDULE 4.1(l), are set forth on SCHEDULE 4.1(m).

                     (ii)   The only Company Employee Benefit Plans that 
individually or collectively would constitute Employee Pension Benefit Plans 
are identified in SCHEDULE 4.1(n).  No Company Employee Benefit Plan is 
subject to the Plan Termination Insurance provisions of Title IV of ERISA.  
The Company and each controlled group member have not incurred any liability 
under Title IV of ERISA arising in connection with the termination of any 
plan covered or previously covered by Title IV of ERISA.

                     (iii)  The Shareholders have delivered to ASI a current, 
complete and correct copy of the Company's Employee Manual (the "Manual"). 
Except as otherwise set forth in SCHEDULE 4.1(n) the Manual lists each 
written, and to the best knowledge of the Shareholders, each oral, 
employment, severance or other similar contract, arrangement or policy and 
each plan or arrangement providing for insurance coverage (including any 
self-insured arrangements), disability benefits, supplemental unemployment 
benefits, vacation benefits, retirement benefits, deferred compensation, 
profit sharing, bonuses, stock options, stock appreciation rights or other 
forms of incentive compensation, reduced interest or interest free loans, 
mortgages, relocation assistance or post-retirement insurance, compensation 
or other benefits that: (A) is not an Employee Benefit Plan; (B) is entered 
into, maintained or contributed to, by the Company and each controlled group 
member and (C) covers any employee or former employee of the Company or any 
controlled group member.  Such contracts, plans and arrangements as are 
described in this Section are referred to collectively as the "Benefit 
Arrangements."  Copies of each of these Benefit Arrangements either are set 
forth in full in the Manual or have been made available to ASI or are listed 
as "Other Benefit Arrangements" on SCHEDULE 4.1(n). The Company has no 
liability under any other Benefit Arrangements that no longer are in effect.

                     (iv)   Except as set forth in any Company Employee 
Benefit Plan or Benefit Arrangement identified in SCHEDULE 4.1(n) and except 
as provided by a Legal Requirement or any collective bargaining agreement or 
any employment contract identified on SCHEDULE 4.1(n), the employment of all 
persons presently employed or retained by the Company is terminable at will.

                     (v)    Except as expressly so identified in SCHEDULE
4.1(n), no Company Employee Benefit Plan is a "Multiemployer Plan."

                     (vi)   No Company Employee Benefit Plan is maintained in
connection with any trust described in Section 501(c)(9) of the Code.  Any
assets of any Company Employee Benefit Plan that are subject to the trust
requirement of ERISA Section 403 are held in trust in compliance with ERISA
Section 403.

                     (vii)  Each Company Employee Benefit Plan that is an
Employer Pension Benefit Plan is intended to be qualified within the meaning of
Section 401(a) of the Code ("Qualified") is so Qualified, has been so Qualified
during the period from its adoption to date, has been administered in a manner
that would not adversely affect its Qualified status and has received a
currently effective determination letter (or a determination letter has been
timely requested) from the Internal Revenue Service that the Plan is (or
continues to be) currently Qualified for federal income tax purposes.  The
Company has delivered to ASI copies of such determination letters and any
pending applications, and copies of such letters and applications have been
attached to this Agreement as part of SCHEDULE 4.1(n).  Each trust in which the
assets of any such Employee Pension Benefit Plan are held is exempt from tax
pursuant to Section 501(a) of the Code.

                     (viii) There have been no prohibited transactions with
respect to any Company Employee Benefit Plan.  No "Fiduciary" (as defined in
Section 3(21) of ERISA) has any liability for breach of fiduciary duty or any
other failure to act or comply in connection with the administration or
investment of the assets of any such Company Employee Benefit Plan.  No action,
suit, proceeding, hearing or investigation with respect to the administration or
the investment of the assets of any Company Employee Benefit Plan (other than
routine claims for benefits) is pending or, to the best knowledge of the
Shareholders is threatened.  To the best knowledge of the Shareholders, there is
no basis for any such action, suit, proceeding, hearing or investigation.

                     (ix)   Except as set forth in SCHEDULE 4.1(n) The Company
and each controlled group member do not maintain and have never maintained nor
contribute, or ever have contributed, or ever have been required to contribute,
to any Company Employee Benefit Plan providing health or medical benefits for
current or future retired or terminated employees, their spouses or their
dependents (other than in accordance with Code Section 4980B).  No condition
exists that would prevent the Company or any controlled group member from
amending or terminating any Company Employee Benefit Plan or Benefit Arrangement
providing health or medical benefits in respect of any active or retired
employees of the Company or any controlled group member (other than in
accordance with Code Section 4980B).

                     (x)    Each Company Employee Benefit Plan and Benefit
Arrangement has been maintained and administered in compliance with its terms
and with the requirements prescribed by any and all Legal Requirements,
including but not limited to ERISA and the Code, that are applicable to such
Plans.  Nothing done or omitted to be done and no transaction or holding of any
asset under or in connection 


                                      28

<PAGE>

with any Company Employee Benefit Plan or Benefit Arrangement has made or 
will make the Company, any controlled group member, any officer or director 
of the Company or of any controlled group member subject to any liability 
under Title I of ERISA or any liability for any Tax under Section 4971, 4972, 
4974 or Section 4975 through 4980B, inclusive, of the Code.

                     (xi)   Any Company Employee Benefit Plan that is a 
"group health plan" (as defined in Code Section 5000(b)(l)) has been 
administered in accordance with the requirements of Part 6 of Subtitle B of 
Title I of ERISA and Code Section 4980B and nothing done or omitted to be 
done in connection with maintenance or administration of any Company Employee 
Benefit Plan that is a "group health plan" has made or will make the Company 
or any controlled group member subject to any liability under Title I of 
ERISA, excise Tax liability under Code Section 4980B or has resulted or will 
result in any loss of income exclusion for a participant under Code Sections 
105(h) or 106.

                     (xii)  There is no contract, agreement, plan or 
arrangement covering any employee or former employee of the Company that, 
individually or collectively, could give rise to the payment of any amount 
that would not be deductible pursuant to the terms of Section 280G or 
162(a)(l) of the Code.

                     (xiii) The Company and each controlled group member have 
made, before the date of this Agreement, all required contributions and 
premium payments under each Company Employee Benefit Plan and Benefit 
Arrangement for all completed fiscal years including contributions that may 
not by law have otherwise been required to be made until the due date for 
filing the Tax Return for any completed fiscal year.

                     (xiv)  Except as disclosed in SCHEDULE 4.1(n), there has 
not been with respect to the Company's or any controlled group member's 
active or retired employees, any amendment to, written interpretation or 
announcement (whether or not written) by the Company relating to, or change 
in employee participation or coverage under, any Company Employee Benefit 
Plan or Benefit Arrangement that would increase the expense of maintaining or 
funding benefits under such Company Employee Benefit Plan or Benefit 
Arrangement above the level of the expense incurred in respect of such for 
the fiscal year ended on December 31, 1997, except as set forth in SCHEDULE 
4.1(n).

                     (xv)   No condition (other than pursuant to a Legal 
Requirement) exists that would have prevented the Company from terminating 
any Company Employee Benefit Plan, prior to the date of this Agreement other 
than the imposition of an excise tax that will arise from the sale of the 
Common Stock by the ESOP.  Except 


                                      29

<PAGE>

as otherwise provided in this Agreement or any employment contract 
entered into upon the Closing of the transactions contemplated by this 
Agreement, the Shareholders acknowledge that ASI will have no obligation to 
any of the Shareholders (other than pursuant to a Legal Requirement) to 
employ any employee of the Company or to continue any Company Employee 
Benefit Plan, and will have no liability to any of the Shareholders under any 
plan or arrangement maintained by the Company for the benefit of any employee.

                     (xvi)  Except as set forth in SCHEDULE 4.1(n) There are 
no retired employees of the Company or any controlled group member who are 
receiving or are entitled to receive any payments from the Company or any 
controlled group member which are not fully funded by an Employee Pension 
Benefit Plan of the Company or a controlled group member.

              (o)    EMPLOYEES AND LABOR.  Since April 30, 1998, the Company 
has not received any notice, and to the best knowledge of the Shareholders, 
there is no reason to believe that any executive or key employee of the 
Company, or any group of employees of the Company, has any plans to terminate 
his, her or its employment with the Company, except as set forth in SCHEDULE 
4.1(o).  No executive or key employee is subject to any agreement, 
obligation, Order or other legal hindrance that impedes or might impede such 
executive or key employee from devoting his or her full business time to the 
affairs of the Company, and, if such person becomes an employee of ASI, to 
the affairs of ASI after the date of this Agreement.  The Company will not be 
required to give any notice under the Worker Adjustment and Retraining 
Notification Act, as amended, or any similar Legal Requirement as a result of 
this Agreement, the Other Shareholder Agreements or the transactions 
contemplated by them.  Except as set forth in SCHEDULE 4.1(o), the Company 
does not have any pending, or to the best of Shareholders' knowledge, 
threatened labor relations problems or disputes, and the Company has not 
experienced any strikes, grievances, claims of unfair labor practices or 
other collective bargaining disputes.  The Company is not a party to and is 
not bound by any collective bargaining agreement, there is no union or 
collective bargaining unit at the Company's facilities, and no union 
organization effort has been threatened, initiated or is in progress with 
respect to any employees of the Company. 

              (p)    CUSTOMER RELATIONSHIPS.  SCHEDULE 4.1(p) lists each
customer (the "Principal Customers") that individually or with its Affiliates
accounted for a Contract Value of $300,000 or more.  To the best knowledge of
the Shareholders and except as set forth in SCHEDULE 4.1(p), the Company has
good commercial working relationships with the Principal Customers.  Since
December 31, 1997, no Principal Customer has canceled or otherwise terminated
its relationship with the Company, materially decreased or limited its
contribution of revenue to the Company, or indicated an intention to take any
such action.  Except as set forth in SCHEDULE 4.1(p), none of the 


                                      30

<PAGE>

Shareholders has any basis to anticipate any material problems with the 
Company's customer, supplier or business relationships.  None of the 
Shareholders have received written or oral communication from a Principal 
Customer that the execution and delivery of this Agreement by either party or 
the consummation of the transactions contemplated by this Agreement will 
cause such Principal Customer to terminate or materially reduce the service 
provided by the Company under its agreements with such Principal Customer 
after the date of this Agreement (other than in connection with normal 
rundowns in services provided as a result of the completion of services 
contemplated in such Agreements).

              (q)    ENVIRONMENTAL MATTERS.  The Company has complied with 
and is in compliance with all Environmental Laws, except to the extent that 
noncompliance with any Environmental Laws, either singly or in the aggregate, 
(i) has not had and will not have any material Adverse Consequences, and (ii) 
will not necessitate any material expenditure by or on behalf of the Company. 
The Company has obtained and adhered to all necessary permits and other 
approvals necessary to treat, transport, store, dispose of and otherwise 
handle hazardous wastes, hazardous materials and hazardous substances (as 
those terms and any similar terms are defined in any Environmental Law, and 
which are referred to in this Agreement as "Hazardous Wastes, Hazardous 
Materials and Hazardous Substances"), a list of all of which permits and 
approvals is set forth on SCHEDULE 4.1(q), and has reported to the 
appropriate authorities, to the extent required by all Environmental Laws, 
all past and present sites owned and operated by the Company where Hazardous 
Wastes, Hazardous Materials or Hazardous Substances have been treated, 
stored, disposed of or otherwise handled.  There have been no releases or 
threats of releases (as defined in Environmental Laws) at, from, in or on any 
property owned or operated by the Company except as permitted by 
Environmental Laws.  There is no on-site or offsite location to which the 
Company has transported or disposed of Hazardous Wastes, Hazardous Materials 
or Hazardous Substances or arranged for the transportation of Hazardous 
Wastes, Hazardous Materials or Hazardous Substances which is the subject of 
any federal, state, local or foreign enforcement action or any other 
investigation which could lead to any claim against the Company, ASI or the 
Surviving Corporation for any clean-up cost, remedial work, damage to natural 
resources, property damage or personal injury.  The Company does not have any 
contingent liability in connection with any release of any Hazardous Waste, 
Hazardous Material or Hazardous Substance into the environment.

              (r)    INTELLECTUAL PROPERTY.  The Company owns or has the legal
right to use each item of Intellectual Property required to be identified on
SCHEDULE 4.1(i).  Except as set forth on SCHEDULE 4.1(r), the sale of the Shares
to ASI will not affect the Company's right to use any such Intellectual
Property.  To the best knowledge of the Shareholders, the continued operation of
the business of the Company as currently conducted will not interfere with,
infringe upon, misappropriate or conflict with any 


                                      31

violate or conflict with any other material restriction of any kind or 
character to which either ASI or Holdings is subject or by which any of their

its capital stock or any securities or obligations convertible into or 
exchangeable for, or giving any person any right to subscribe for or acquire

              (j)    ABSENCE OF MATERIAL ADVERSE CHANGE.  Since April 30, 
1998, to the date of this Agreement, ASI has not experienced any material 
adverse change to its assets, its business, or its business prospects.  As of 
the date of this Agreement, there is no existing event or condition as to 
which ASI is required to file a Current Report on Form 8-K, and no pending 
transactions (other than the transaction contemplated by this Agreement) or 
anticipated events or conditions that would require the filing of a Current 
Report on Form 8-K, which has not previously been disclosed in the SEC 
Reports.

              (k)    BROKERS.  ASI retained Dain Rauscher Incorporated

the transactions contemplated by this Agreement.  Any finder's fee, brokerage 
commission, or similar payment owed to Dain will be paid by ASI.

       4.3    REPRESENTATIONS AS TO KNOWLEDGE.  Any representation and 
warranty made in Article IV to the "best knowledge" of a party means matters 
actually known by such party and matters which would come to such party's

case of the Shareholders, inquiry of Martin Epner, Albert Naumann III, Dan 
DeCourcy, Don Fryhover, Kenneth Clifford, John Federowicz, Linda Kane, and 
Wendy Martin and (ii) in the case of ASI and Holdings, inquiry of Sidney V. 
Corder, Scott C. Benger, John J. Dillon, III, and Randal J. Sage.  Any matter

Shareholders.  Any matter that is within the actual knowledge or Constructive 
Knowledge of Sidney V. Corder, Scott C. Benger, John J. Dillon, III, or 
Randal J. Sage will be deemed to be within the best knowledge of ASI and 
Holding.

all necessary transfer tax and other revenue stamps, acquired at the 
Shareholders' expense, affixed and canceled, and (b) ASI will deliver to the 
Shareholders certificates representing the Common Stock and ASI's check or 
checks in payment of the cash portion of the Merger consideration.  Any cash 
payments will be wired to the Shareholders pursuant to wiring instructions 
provided by the Shareholders' Agent.  The Shareholders agree promptly to cure 
any deficiencies with respect to the endorsement of the stock certificates or 
other documents of conveyance with respect to such Shares or with respect to 
the stock powers accompanying any Shares.

       7.3    TERMINATION.  (a)  If the Closing has not occurred by July 10, 
1998, any party may terminate this Agreement by notice to the other parties, 
but any such termination will not relieve any party (including the 
terminating party) from liability for any breach of this Agreement occurring 
prior to such termination.

       (b)    If on June 26, 1998, the closing price of the Common Stock on 
Nasdaq, when multiplied by the number of shares of Common Stock to be issued 
to the ESOP under Section 2.6(a)(ii), plus the cash payable to the ESOP under 
Section 2.6(a)(ii), does not equal at least $5,266,123 (such closing price 
being referred to as the "Target Price"), then ASI, upon notice to the 
Shareholders' Agent (given not later than June 27, 1998), may terminate this 
Agreement, without liability (but any such termination will not relieve any 
party, including ASI, from liability for any breach of this Agreement 
occurring prior to such termination), or ASI may issue such number of 
additional shares of Common Stock to the ESOP such that the sum of the shares 
of Common Stock to be issued to the ESOP under Section 2.6(a)(ii), plus such 
number of additional shares of Common Stock, multiplied by the closing price 
of the Common Stock on the Business Day prior to the Closing Date, plus the 
cash payable to the ESOP under Section 2.6(a)(i), equals $5,266,123.  If, 
under the provisions of the first sentence of this Section 7.3(b), ASI does 
not elect to terminate this Agreement on June 27, 1998, or to issue such 
additional shares of Common Stock, and if on none of the Business Days 
between June 26, 1998, and July 9, 1998, inclusive (the "Closing Period"), 
the closing price of the Common Stock on Nasdaq equals or exceeds the Target 
Price, then ASI, upon notice to the Shareholders' Agent (given not later than 
July 10, 1998), may terminate this Agreement, without liability (but any such 
termination will not relieve any party, including ASI, from liability for any 
breach of this Agreement occurring prior to such termination).  If ASI, under 
the provisions of the first sentence of this Section 7.3(b), has not elected 
to terminate this Agreement on June 27, 1998 or to issue such additional 
shares of Common Stock, and if at any time during the Closing Period, the 
Target Price is reached, ASI will have no right to terminate this Agreement 
under this Section 7.3(b), and, if all the other conditions to ASI's 
obligations to consummate the transactions under this Agreement have been 
satisfied, ASI will be obligated to consummate the transactions contemplated 
by this Agreement on the next Business Day after such Target Price is reached 
during the Closing Period.  Under any circumstance in which a closing occurs 
and the closing price of the Common Stock on Nasdaq on the Business Day prior 
to the Closing Date does not equal or exceed the Target Price, then ASI will 
issue such number of additional shares of Common Stock such that the sum of 
the shares of Common Stock to be issued to the ESOP under Section 2.6(a)(ii), 
plus such number of additional shares of Common Stock, multiplied by the 
closing price of the Common Stock on Nasdaq on the Business Day prior to the 
Closing Date, plus the cash payable to the ESOP under Section 2.6(a)(i), 
equals $5,266,123.


                                    ARTICLE VIII.
                                POST-CLOSING COVENANTS

The parties agree as follows with respect to the period following Closing.


                                      47

<PAGE>

       8.1    FURTHER ASSURANCES.  If after Closing any further action is 
necessary or desirable to carry out the purposes of this Agreement, each of 
the parties will take such further action as any other party reasonably may 
request, all at the sole cost and expense of the requesting party (unless the 
requesting party is entitled to indemnification for such action under Article 
IX).  Such further action includes, but is not limited to, the execution and 
delivery of additional instruments and documents and the use of the 
Shareholders' reasonable best efforts to obtain any requested consent or 
approval from a Principal Customer.

       8.2    COOPERATION.  If and for so long as any party actively is 
contesting or defending against any action, suit, proceeding, hearing, 
investigation, charge, complaint, claim or demand in connection with (a) any 
transaction contemplated by this Agreement or (b) any fact, situation, 
circumstance, status, condition, activity, practice, plan, occurrence, event, 
incident, action, failure to act or transaction on or prior to the Closing 
Date involving any of the Company's assets or business, each of the other 
parties will cooperate with such party and its counsel in the contest or 
defense, make available their personnel, and provide such testimony and 
access to their books and records as will be reasonably necessary in 
connection with the contest or defense, all at the sole cost and expense of 
the contesting or defending party (unless the contesting or defending party 
is entitled to indemnification under Article IX).

       8.3    POST-CLOSING ANNOUNCEMENTS.  Following Closing, the 
Shareholders will not issue any press release or make any public announcement 
relating to the subject matter of this Agreement without the prior written 
approval of ASI and the Shareholders' Agent.

       8.4    FINANCIAL STATEMENTS.  The Shareholders will, upon request of 
ASI, cooperate with ASI to produce such historical and on-going financial 
statements and audits concerning the Company as ASI may request, all at the 
sole cost and expense of ASI.

       8.5    ACCESS TO BOOKS AND RECORDS.  Following the Closing, ASI and 
Holdings will permit the Shareholders and their authorized representatives, 
during normal business hours and upon reasonable notice, to have access to, 
and examine and make copies of, all books and records of the Company which 
relate to transactions or events occurring on or prior to the Closing Date 
and transactions or events occurring subsequent to the Closing Date which are 
related to or arise out of transactions or events occurring prior to the 
Closing Date, to the extent reasonably necessary for the Shareholders to 
defend any claim for indemnification under this Agreement, or to prepare any 
tax return or effectively defend any tax audit or claim relating to periods 
prior to the Closing.


                                      48

       8.6    CERTAIN TAX MATTERS.

              (a)    TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE.  ASI 
will prepare or cause to be prepared and filed or caused to be filed all Tax 
Returns for the Company for all periods ending on or prior to the Closing 
Date which are filed after the Closing Date.  Tax returns relating to periods 
ending on or prior to the Closing Date will be prepared by KPMG Peat Marwick. 
 ASI will permit the Shareholders' Agent to review and comment on each such 
Tax Return described in the preceding sentence prior to filing.  In the event 
the Shareholders' Agent does not agree with any Tax Return prepared by ASI, 
Shareholders' Agent will notify ASI within 20 days after receipt of such Tax 
Return.  Upon ASI's receipt of such notice, the parties will endeavor to 
reach an agreement on the disputed item(s) in the Tax Return.  If ASI and the 
Shareholders' Agent are unable to resolve the dispute, then the Shareholders 
will reimburse ASI for the Taxes of the Company that Shareholders' Agent 
believes are due.  Any excess disputed amount will be submitted by ASI as a 
claim to the Escrow Agent and will be resolved in accordance with the terms 
of the Escrow Agreement.  The Shareholders will reimburse ASI for any 
undisputed Taxes of the Company and its subsidiaries with respect to such 
periods within 15 days after payment by ASI of such Taxes to the extent such 
Taxes are not reflected in the reserve for Tax liability (rather than any 
reserve for deferred Taxes established to reflect timing differences between 
book and Tax income) shown on the face of the Closing Date Balance Sheet.

              (b)    COOPERATION ON TAX MATTERS.  ASI, Holdings, the 
Shareholders, and the Shareholders' Agent will cooperate fully, as and to the 
extent reasonably requested by the other parties, in connection with the 
filing of Tax Returns pursuant to this Section and any audit, litigation or 
other proceeding with respect to Taxes.  Such cooperation will include the 
retention and (upon the other party's request) the provision of records and 
information which are reasonably relevant to any such audit, litigation or 
other proceeding and making employees available on a mutually convenient 
basis to provide additional information and explanation of any material 
provided under this Subsection.  ASI and the Shareholders agree: (i) to 
retain all books and records with respect to Tax matters pertinent to the 
Company relating to any taxable period beginning before the Closing Date 
until the expiration of the statute of limitations (and, to the extent 
notified by ASI or the Shareholders' Agent, any extensions thereof) of the 
respective taxable periods, and to abide by all record retention agreements 
entered into with any taxing authority, and (ii) to give the other parties 
reasonable written notice prior to the transferring, destroying or discarding 
of any such books and records, and, if any of the other parties so request, 
to allow such other parties to take possession of such books and records.  
ASI, the Shareholders, and the Shareholders' Agent further agree, upon 
request, to use their best efforts to obtain any certificate or other 
document from any governmental authority or any other Person as may be 
necessary to mitigate, reduce or 


                                      49

<PAGE>

eliminate any Tax that could be imposed, including without limitation, with 
respect to the transactions contemplated by this Agreement.

       8.7    EMPLOYEE MATTERS.  The employees of the Company will become 
employees of the Surviving Corporation following the Merger, and such 
employment will be employment at will or in accordance with contracts in 
effect at the Effective Date. Surviving Corporation recognizes that employees 
of the Company have accrued unused vacation as of the date of the Merger.  
Surviving Corporation acknowledges the liability for accrued unused vacation 
and will permit such employees to use such unused vacation time over a 
reasonable period after the Closing.  Thereafter, for so long as the 
employees of the Surviving Corporation are employed by the Surviving 
Corporation, and except to the extent that any of them may have written 
employment agreements with ASI that provide to the contrary, (a) ASI may 
cause them to be paid, depending on their duties and responsibilities, in 
accordance with the compensation policies of ASI, with respect to its 
employees generally; (b) the Company's employee benefit plans may be 
terminated as soon as practicable after the Effective Date; and (c) to the 
extent that the Company's employee benefit plans are so terminated, the 
employees of the Company will be entitled to participate in the benefit plans 
that ASI maintains for its employees generally on substantially the same 
terms and conditions as other employees of ASI.  For this purpose, each "year 
of service" with the Company will be treated as a "year of service" with ASI.


                                     ARTICLE IX.
                       REMEDIES FOR BREACHES OF THIS AGREEMENT

       9.1    INDEMNIFICATION BY ASI.  From and after Closing, ASI will 
indemnify, defend and hold harmless the Shareholders and their heirs, 
personal representatives, successors and permitted assigns (the "Shareholder 
Indemnitees") from and against any and all Adverse Consequences resulting or 
arising from, relating to or incurred in connection with: (a) any breach of 
any representation, warranty or covenant of ASI or Holdings contained in this 
Agreement or in any of the Other ASI Agreements, and (b) any broker's or 
finder's fee or other commission resulting from any services alleged to have 
been rendered to or at the request of ASI or Holdings with respect to this 
Agreement or any of the transactions contemplated by this Agreement.  The 
foregoing indemnification obligations will survive the Closing except to the 
extent limited by Section 11.13.

       9.2    INDEMNIFICATION BY SHAREHOLDERS.  From and after Closing, the 
Non-ESOP Shareholders and, subject to Section 9.5(a), the ESOP will 
indemnify, defend and hold harmless ASI, Holdings, the Company and their 
respective officers, directors and controlling persons (the "ASI 
Indemnitees") from and against any and all Adverse Consequences resulting or 
arising from, relating to or incurred in connection with: (a) 


                                      50

<PAGE>

any breach of any representation, warranty, or covenant of any of the 
Shareholders contained in this Agreement or in any of the Other Shareholder 
Agreements, (b) any broker's or finder's fee or other commission resulting 
from any services alleged to have been rendered to or at the request of any 
of the Shareholders or the Company with respect to this Agreement or any of 
the transactions contemplated by this Agreement (other than the fee payable 
to Duncan as described in Section 4.1(s)); and (c) any Environmental 
Obligation incurred by any ASI Indemnitee, resulting or arising from, 
relating to or incurred in connection with (i) any event, fact, circumstance 
or condition (to the extent any such event, fact, circumstance or condition 
occurred or existed at or prior to the Closing and even if the Adverse 
Consequence manifests itself after the Closing) and (ii) any act or omission 
(to the extent such act or omission occurred prior to the Closing Date and 
even if the Adverse Consequence manifests itself after the Closing), (d) any 
Adverse Consequence incurred by any ASI Indemnitee, resulting or arising 
from, relating to or incurred in connection with (i) the Company's purchase, 
sale, or ownership of shares of common stock of Conic Systems, Inc. or of 
CANTEX Conversion Services, Inc., (ii) the operations, property ownership, 
tax obligations, Legal Requirements, management, or contract obligations of 
Conic Systems, Inc. or of CANTEX Conversion Services, Inc., including any and 
all claims against any ASI Indemnitee by any past or present shareholder, 
officer, director, employee, consultant, manager, agent, creditor of Conic 
Systems, Inc. or of CANTEX Conversion Services, Inc., whether any event, 
fact, circumstance, condition, act or omission, giving rise to such Adverse 
Consequence occurs or manifests itself before or after the Closing Date, and 
(e) any Adverse Consequence incurred by any ASI Indemnitee, resulting or 
arising from, relating to or incurred in connection with any claim made or to 
be made after the date of this Agreement by Timothy W. Smith against any ASI 
Indemnitee (the "Smith Claim"), including claims for lost wages and benefits, 
attorney's fees, costs of court, interest, exemplary damages, stock, and 
stock option rights.  The foregoing indemnification obligations will survive 
the Closing except to the extent limited by Section 11.13.

       9.3    [RESERVED.]

       9.4    NOTICE OF CLAIM; RIGHT TO PARTICIPATE IN AND DEFEND THIRD PARTY 
CLAIM.

              (a)    If any indemnified party receives notice of the 
assertion of any claim, the commencement of any suit, action or proceeding, 
or the imposition of any penalty or assessment by a third party in respect of 
which indemnity may be sought under this Agreement (a "Third Party Claim"), 
and the indemnified party intends to seek indemnity under this Agreement, 
then the indemnified party will promptly provide the indemnifying party with 
prompt written notice of such Third Party Claim, but in any event not later 
than 30 calendar days after receipt of such notice of Third Party Claim.  The 
failure by an indemnified party to notify an indemnifying party of a Third 
Party Claim will 


                                      51

<PAGE>

not relieve the indemnifying party of any indemnification responsibility 
under this Article, except to the extent, if any, that such failure 
prejudices the ability of the indemnifying party to defend such Third Party 
Claim.

              (b)    The indemnifying party will have the right to control 
the defense, compromise or settlement of a Third Party Claim with its own 
counsel (reasonably satisfactory to the indemnified party) if the 
indemnifying party delivers written notice to the indemnified party within 
seven days following the indemnifying party's receipt of notice of a Third 
Party Claim from the indemnified party which acknowledges its obligations to 
indemnify the indemnified party with respect to such Third Party Claim in 
accordance with this Article; provided, however, that the indemnifying party 
will not enter into any settlement of any Third Party Claim which would 
impose or create any obligation or any financial or other liability on the 
part of the indemnified party if such liability or obligation (i) requires 
more than the payment of a liquidated sum or (ii) is not covered by the 
indemnification provided to the indemnified party under this Agreement.  In 
its defense, compromise or settlement of any Third Party Claim, the 
indemnifying party will timely provide the indemnified party with such 
information with respect to such defense, compromise or settlement as the 
indemnified party may request, and will not assume any position or take any 
action that would impose an obligation of any kind on, or restrict the 
actions of, the indemnified party.  The indemnified party will be entitled 
(at the indemnified party's expense) to participate in, but not control, the 
defense by the indemnifying party of any Third Party Claim with its own 
counsel.

              (c)    If the indemnifying party does not undertake the 
defense, compromise or settlement of a Third Party Claim in accordance with 
subsection (b) of this Section, the indemnified party will have the right to 
control the defense or settlement of such Third Party Claim with counsel of 
its choosing; provided, however, that the indemnified party will not settle 
or compromise any Third Party Claim without the indemnifying party's prior 
written consent (which consent will not be unreasonably withheld), unless the 
terms of such settlement or compromise release the indemnified party or the 
indemnifying party from any and all liability with respect to the Third Party 
Claim.  The indemnifying party will be entitled (at the indemnifying party's 
expense) to participate in the defense of any Third Party Claim with its own 
counsel.

              (d)    The indemnified party will assert any indemnifiable 
claim under this Agreement that is not a Third Party Claim by promptly 
delivering notice of such claim to the indemnifying party. If the 
indemnifying party does not respond to such notice within 60 days after its 
receipt, it will have no further right to contest the validity of such claim.

              (e)    Notwithstanding the foregoing provisions, ASI will have 
the right to control the prosecution of the declaratory judgment action 
involving the Smith Claim and the defense of any claims brought by Timothy W. 
Smith prior to or after the date of 


                                      52

<PAGE>

this Agreement, with counsel reasonably acceptable to the Shareholders' 
Agent, and to settle or compromise the Smith Claim, with the consent of the 
Shareholders' Agent, such consent not to be unreasonably withheld.  Any costs 
incurred by ASI involving the Smith Claim, including attorneys' fees and 
costs of settlement will be an indemnifiable expense of the Shareholders.

       9.5    LIMITATIONS.

              (a)    The maximum aggregate amount that the ASI Indemnitees 
may recover on account of all Adverse Consequences under this Article IX will 
be limited to $9,000,000, and the maximum aggregate amount that the ASI 
Indemnitees may recover from the ESOP is that portion of the ESOP's cash and 
Common Stock received at Closing that has been deposited into Escrow pursuant 
to the terms of the Escrow Agreement.

              (b)     The indemnification provisions of this Article will 
constitute the exclusive remedy by either party against the other arising by 
virtue of a breach of any representation, warranty, or covenant under this 
Agreement, absent fraud.  The foregoing provision is not intended to limit 
any party from seeking recourse against the other party under any law that 
provides a cause of action that is independent of the rights granted by this 
Agreement.

              (c)    Notwithstanding the provisions of this Article, upon the 
Effective Date, the Company will not have any duty, except to the extent 
covered by insurance, to indemnify any of the Shareholders (whether in their 
capacities as officers, directors or otherwise) or to contribute funds for 
the benefit of any of the Shareholders, under the articles of incorporation 
or bylaws of the Company, under any resolution, contract, insurance policy, 
arrangement or understanding, or under the provisions of any statute 
governing the Company, or otherwise, to the extent that the facts, 
circumstances, or events that otherwise would give rise to a claim of 
indemnification or contribution constitute a breach of a representation, 
warranty or covenant under this Agreement, regardless of any limitation 
period under Section 11.13(b) or (c).  

              (d)    The amounts for which the indemnifying party is liable 
to the indemnified party under this Article will be increased by interest on 
the amount of Adverse Consequences, at a rate equal to two percentage points 
above the Prime Rate, accrued from the Liquidation Date.

              (e)    No ASI Indemnitee will be entitled to indemnification 
for a breach by any of the Shareholders of a representation and warranty in 
Section 4.1 to the extent that (i) any of Sidney V. Corder, Scott C. Benger, 
John J. Dillon, III, or Randal J. Sage at or prior to the Closing had actual 
knowledge of the fact or circumstance constituting 


                                      53

<PAGE>

such breach and at or prior to the Closing had actual knowledge that such 
fact or circumstance constituted a breach, and (ii) no Shareholder and none 
of Martin Epner, Albert Naumann III, and Wendy Martin had actual knowledge of 
such fact or circumstances.

       9.6    BASKET AND DEDUCTIBLE.  Except as provided in the immediately 
succeeding sentence, no indemnified party will be entitled to indemnification 
from an indemnifying party under Sections 9.1 or 9.2 unless and until the 
aggregate amount of Adverse Consequences with respect to which all ASI 
Indemnitees or Shareholder Indemnitees, as the case may be, would otherwise 
be entitled to assert under Section 9.1 or 9.2, whichever is applicable, 
exceeds $200,000, at which point the indemnified party will be entitled to 
indemnification for all Adverse Consequences.  ASI will be entitled to seek 
indemnification with respect to the Smith Claim without regard to the 
foregoing provision, and any amount paid to ASI with respect to the Smith 
Claim will not count against the $200,000 basket provided for in the 
preceding sentence.

       9.7    OBLIGATIONS OF SHAREHOLDERS.  All of the obligations of the 
Shareholders under this Agreement, including obligations arising from any 
breach of a representation and warranty under Section 4.1 or Section 4.2 and 
indemnification obligations under Section 9.2, are (a) except as provided in 
this Section 9.7, joint and several as between the Shareholders as a group on 
the one hand, and ASI or Holdings on the other hand, and (b) are pro rata 
(based upon the number of Shares owned by such Shareholder over the total 
number of Shares owned by all Shareholders) as among the Shareholders, except 
that once the ESOP's interest in the Escrow has been exhausted to cover 
indemnification claims of ASI Indemnitees, the Non-ESOP Shareholders will be 
liable on a joint and several basis as between such Non-ESOP Shareholders 
and, as among Non-ESOP Shareholders, will be liable on a pro rata basis 
(based on the number of Shares owned by such Non-ESOP Shareholder over the 
total number of Shares owned by all Non-ESOP Shareholders (such that the ASI 
Indemnitees will be indemnified with respect to all Adverse Consequences 
(subject to Sections 9.5(a) and 9.6) even if recourse against the ESOP may be 
limited).  Notwithstanding the foregoing, the obligations of the Shareholders 
are several as to any breach of a representation or warranty set forth in the 
first three sentences of Section 4.1(c) and in Section 4.1(d)(i) and (ii). 

       9.8    SHAREHOLDER WAIVER.  

              (a)    Effective on the Effective Date, without any further 
action required by any party, the Shareholders (but with respect to the ESOP 
only to the extent not prohibited by section 410 of ERISA) waive (the 
"Waiver") any and all obligations, claims, liabilities, actions, suits, 
proceedings or demands of any kind or character, including but not limited 
to, claims for indemnification, which any of such Shareholders 


                                      54

<PAGE>

now has or may hereafter have against the Company based upon events, actions 
or omissions occurring or claims arising prior to the date of this Agreement, 
whether or not such Shareholder has knowledge of such claims (the "Claims").  
The Waiver includes, but is not limited to, Claims arising under any (i) 
agreement, arrangement, or understanding (whether or not in writing), (ii) 
any articles of incorporation, certificate of incorporation, bylaws or other 
documents, and (iii) under common law, and any Claims for indemnification 
against the Company which might arise as a result of a claim made against any 
Shareholder by any third party or by any other Shareholder.

              (b)    In connection with the Waiver each Shareholder represents
and warrants to the Company as follows:

                     (i)    Such Shareholder has received independent legal
advice from his or its attorneys, to the extent that such Shareholder has deemed
necessary, with respect to the advisability of making the Waiver.

                     (ii)   Except for the representations and warranties
contained in this Section 9.6, neither the Company, nor any agent, employee,
representative or attorney for the Company, has made any statement or
representation to such Shareholder to induce such Shareholder in making the
Waiver, and none of such Shareholders has relied upon any such statement,
representation or promise of the Company, or any agent, employee, representative
or attorney for the Company, in making the Waiver.

                     (iii)  Such Shareholder has made such investigation of the
facts pertaining  to the Waiver and of all the matters pertaining to it as he or
it deemed necessary, and no such  Shareholder has been induced by any promise or
representation by the Company or any of their respective agents, employees,
representatives or attorneys with respect to any such matter.

                     (iv)   Such Shareholder has read this Section 9.6 and
understands its contents. 

                     (v)    In making the Waiver, such Shareholder assumes the
risk of any misrepresentation, concealment or mistake, and if such Shareholder
should subsequently discover that any fact was concealed from him or it, or that
his or its understanding of the facts or of the law was incorrect, such
Shareholder will not be entitled to set aside the Waiver by reason of this
Agreement. The Waiver is intended to be final and binding regardless of any
claims of misrepresentations, promise made without the intention of performance,
concealment of fact, mistake of fact or law, or any other circumstances
whatsoever.

                                        55

<PAGE>

              (c)    Each Shareholder covenants not to commence any action,
lawsuit or other legal proceeding in law or in equity against the Company based
upon or arising out of any fact or matter covered by the Waiver.

                     (i)    Should any Shareholder, at any time after such
Shareholder makes the Waiver, commence any action, lawsuit or other legal
proceeding, in law or in equity or otherwise, in breach of the covenant not to
sue contained in this Section 9.6, such Shareholder by this Agreement agrees to
indemnify and hold harmless the Company from and against any liability, loss,
cost, expense or judgment arising out of or occasioned by such action, including
but not limited to, the amount of any judgment or settlement entered into in
resolution of said action and attorneys' fees.

                     (ii)   If any Shareholder, at any time after such
Shareholder makes the Waiver, commences any action, lawsuit or other legal
proceeding, in law or in equity or otherwise against any Person, and in
connection with such action, lawsuit or other legal proceeding, such Person
makes a claim for indemnification against the Company, such Shareholder by this
Agreement agrees to indemnify and hold harmless the Company from and against any
liability, loss, cost, expense or judgment arising out of or occasioned by such
action by such Person, including but not limited to, the amount of any judgment
or settlement entered into in resolution of said action and attorneys' fees.

              (d)    Each Shareholder represents and warrants that he or it has
not prior to the date of this Agreement assigned or transferred or purported to
assign or transfer, to any person or entity, any claims or matters released
pursuant to the Waiver. Each Shareholder further covenants that he or it will
not at any time after the date of this Agreement, assign or transfer or purport
to assign or transfer, to any person or entity, any claims or matters, known or
unknown, released pursuant to the Waiver. Each Shareholder by this Agreement
agrees to indemnify and hold harmless the Company from and against any loss,
cost or expense, including but not limited to, attorneys' fees, arising out of
or occasioned by, or arising in connection with, any such assignment or
transfer, or any purported such assignment or transfer, of any claims or other
matters released pursuant to the Waiver.

              (e)    The releases made by the Shareholders pursuant to the
Waiver will inure to the benefit of and will be binding upon the heirs, personal
representatives, successors and assigns of the Company.

       9.9    ESCROW WITHDRAWAL.  The ASI Indemnitees will be required to seek
recourse first against the cash in the Escrow Account and then against the
shares of Common Stock deposited in the Escrow Account before seeking recourse
directly 

                                        56

<PAGE>

against the Shareholders for any indemnification obligation of the 
Shareholders under this Article.  The ASI Indemnitees may, however, 
immediately seek recourse directly against the Shareholders, other than the 
ESOP, if the sum of cash held in the Escrow Account plus the Credited Value 
of the escrowed Common Stock, determined as of the Liquidation Date, of any 
claim by the ASI Indemnitees, is less than the amount reasonably claimed by 
all ASI Indemnitees under all outstanding claims as to which a Liquidation 
Date has occurred. Notwithstanding the existence of an Escrow Account, 
nothing will prevent the Shareholders from paying cash in satisfaction of 
their indemnification obligations under this Article.  The ASI Indemnitees 
right to seek recourse against the ESOP is limited to the amount of cash and 
Common Shares deposited by the ESOP into the Escrow Account.

       9.10   SHAREHOLDER ACKNOWLEDGMENT.  

TO THE EXTENT THE PROVISIONS OF THIS AGREEMENT MAY PROVIDE FOR INDEMNIFICATION
FOR AN ASI INDEMNITEE'S OWN NEGLIGENT ACTS, EACH SHAREHOLDER ACKNOWLEDGES THAT
IT UNDERSTANDS AND ACCEPTS SUCH PROVISIONS.

                                      ARTICLE X.
                            ALTERNATIVE DISPUTE RESOLUTION

       10.1   MEDIATION.  If a dispute arises under or in connection with this
Agreement, including, without limitation, those involving claims for specific
performance or other equitable relief, notice must be given pursuant to Section
11.6.  After such notice has been given by one party to the other, the parties
in good faith will attempt to negotiate or mediate a resolution of the dispute
with the aid of a mediator who has been mutually agreed upon by the parties.

       10.2   ARBITRATION.   If such efforts provided for in Section 10.1 do not
within 30 days resolve the dispute, upon demand of any party, whether made
before or after the institution of any judicial proceeding, the dispute will be
resolved by binding arbitration under the Commercial Arbitration Rules of the
American Arbitration Association.  Institution of a judicial proceeding by a
party does not waive the right of that party to demand arbitration under this
Agreement, provided that arbitration is commenced within 70 days after such
judicial proceedings are commenced.  Disputes may include, without limitation,
tort claims, counterclaims, claims brought as class actions, claims arising from
documents executed in the future, or claims arising out of or connected with the
transactions contemplated by this Agreement and the Other ASI Agreements and
Other Shareholder Agreements.  The American Arbitration Association will choose
one arbitrator to hear the parties and settle any dispute.  All arbitration
hearings will be conducted in Kansas City, Missouri.  Any pre-trial discovery
and/or depositions will be 

                                        57

<PAGE>

conducted in the venue of the party against whom discovery is sought or in 
the venue of the party being deposed, respectively. All applicable statutes 
of limitation will apply to any dispute.  The arbitrator will have no power 
to award punitive or exemplary damages, to ignore or vary the terms of this 
Agreement or any Other ASI Agreement or Other Shareholder Agreement, and will 
be bound to apply controlling law.  The Shareholders and ASI each will pay 
for one-half of the arbitrator's fees and expenses and each such party will 
bear its own costs and expenses incurred in connection with the arbitration, 
except that the arbitrator will award either party reimbursement of its share 
of the costs and expenses of arbitration, such party's costs and expenses 
(including attorneys' fees and expenses), and any special or extraordinary 
fees or costs incurred by the Escrow Agent in connection with any such 
arbitration or dispute, if the other party commences or conducts the 
arbitration in bad faith.  A judgment upon the award may be entered in any 
court having jurisdiction.  Notwithstanding anything to the contrary 
contained in this Section 10.2, the parties preserve, without diminution, 
certain remedies that any of them may employ or exercise freely, either 
alone, in conjunction with, or during a dispute.  The parties to this 
Agreement have the right to proceed in any court of proper jurisdiction or by 
self-help to exercise or prosecute the following remedies, as applicable: (i) 
all rights of self-help including peaceful occupation of real property and 
collection of rents, set off and peaceful possession of personal property; 
(ii) obtaining provisional or ancillary remedies including temporary 
injunctive relief, sequestration, garnishment, attachment, appointment of a 
receiver and filing an involuntary bankruptcy proceeding; and (iii) when 
applicable, a judgment by confession of judgment.  All awards of permanent 
injunctive relief may be awarded only by the arbitrator.  Preservation of 
these remedies does not limit the power of an arbitrator to grant similar 
remedies that may be requested by a party in a dispute.

                                     ARTICLE XI.
                                    MISCELLANEOUS

       11.1   NO THIRD-PARTY BENEFICIARIES.  This Agreement will not confer any
rights or remedies upon any Person other than the parties and their respective
successors and permitted assigns.

       11.2   ENTIRE AGREEMENT.  This Agreement (including the Other Shareholder
Agreements and Other ASI Agreements) constitutes the entire agreement among the
parties and supersedes any prior understandings, agreements or representations
by or among the parties, written or oral, to the extent they relate in any way
to the subject matter of this Agreement.

       11.3   SUCCESSION AND ASSIGNMENT.  This Agreement will be binding upon
and inure to the benefit of the parties and their respective successors and
permitted assigns.  At or after the Closing, any party may assign his or its
rights under this 

                                        58

<PAGE>

Agreement as permitted by law, including, without limitation, any assignment 
of any claim of indemnification to any debt or equity financing source, but 
no assignment will release the assigning party of his or its obligations 
under this Agreement.

       11.4   COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which will be deemed an original and all of which together
will be deemed to be one and the same instrument.  The execution of a
counterpart of the signature page to this Agreement will be deemed the execution
of a counterpart of this Agreement.

       11.5   HEADINGS.  The section headings contained in this Agreement are
inserted for convenience only and will not affect in any way the meaning or
interpretation of this Agreement.

       11.6   NOTICES.  All notices, requests, demands, claims, and other

day is not a Business Day).  Any party may change the address to which notices,
requests, demands, claims and other communications under this Agreement are to
be delivered by giving the other parties notice in the manner set forth in this
Agreement.

       11.7   GOVERNING LAW.  This Agreement will be governed by and construed
in accordance with the domestic laws of the State of Texas without giving effect
to any choice or conflict of law provision or rule (whether of the State of
Texas or any other jurisdiction) that would cause the application of the laws of
any jurisdiction other than the State of Texas.

       11.8   AMENDMENTS AND WAIVERS.  No amendment of any provision of this
Agreement will be valid unless the same is in writing and signed by ASI,
Holdings and all of the Shareholders (unless signature is only required by the
Shareholders' Agent pursuant to Section 3.1).  No waiver by any party of any
default, misrepresentation or breach of warranty or covenant under this
Agreement, whether intentional or not, will be deemed to extend to any prior or
subsequent default, misrepresentation or breach of warranty or covenant under
this Agreement or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence, and no waiver will be effective unless set forth in
writing and signed by the party against whom such waiver is asserted.

       11.9   SEVERABILITY.  Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction will not affect
the validity or enforceability of the remaining terms and provisions of this
Agreement or the validity or 

                                        60

<PAGE>

enforceability of the offending term or provision in any other situation or

       11.10  EXPENSES.  Except as otherwise provided in this Agreement, ASI,
Holdings, the Company, and each of the Shareholders will each pay any and all
fees and expenses incurred by it, or him or them in connection with the

acknowledges that the fees and expenses of Chucker & Reibach have been incurred 
by the Company and not the Shareholders.

       11.11  CONSTRUCTION.  The parties have participated jointly in the
negotiation and drafting of this Agreement.  If an ambiguity or question of
intent or interpretation arises, this Agreement will be construed as if drafted
jointly by the parties and no presumption or burden of proof will arise favoring
or disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement.  The word "including" will mean including without limitation. 
The parties intend that each representation, warranty and covenant contained in
this Agreement will have independent significance.  If any party breaches any
representation, warranty or covenant contained in this Agreement in any respect,
the fact that there exists another representation, warranty or covenant relating
to the same subject matter (regardless of the relative levels of specificity)
which the party has not breached will not detract from or mitigate the fact that
the party is in breach of the first representation, warranty or covenant.

       11.12  INCORPORATION OF EXHIBITS AND SCHEDULES.  The Exhibits and
Schedules identified in this Agreement are incorporated in this Agreement by
reference and made a part of this Agreement.

       11.13  SURVIVAL.  The representations and warranties made in this
Agreement will survive the Closing Date until two years after the Closing Date,
except that: 

              (a)    the representations and warranties of the Shareholders in
Sections 4.1(a), (b), (c), (d)(ii)(A) and d(iii)(A) will survive forever;

              (b)    the representations and warranties of ASI and Holdings in
Sections 4.2(a), (b), (c) (but only as to clauses (i) and (iii) of Section
4.2(c)), (d), (f), and (i) will survive forever; and 

              (c)    the representations and warranties of the Shareholders in
Sections 4.1(g) and (n) will survive until the expiration of the applicable
statutes of limitations with respect to any such claims that could be brought
regarding such matters (including any extensions of any statutes of
limitations), plus a period of 60 days.  

                                        61

<PAGE>

No party will have any obligation to indemnify any person pursuant to this
Agreement with respect to any breach of a representation or warranty unless a
specific claim has been validly made under this Agreement on or prior to the
applicable period set forth above, except that, if a party has a reasonable
basis to believe that an indemnifiable claim will arise and gives notice to the
other party concerning such matter within the applicable period set forth above,
then all rights of such party to seek indemnification with respect to such

<PAGE>

     Prior to any proposed transfer of any Restricted Stock (other than under

give written notice to ASI of its intention to effect such transfer.  Each such
notice will describe the manner of the proposed transfer and, if requested by

which point such Restricted Stock may be transferred in accordance with the
terms of its notice.  Each certificate of Restricted Stock transferred as
provided above will bear the legend set forth in Section 2, unless (i) such
transfer is in accordance with the provisions of Rule 144 (or any other rule
permitting public sale without registration under the Securities Act) or (ii)
the opinion of counsel referred to above is to the further effect that the
transferee and any subsequent transferee would be entitled to transfer such
securities in a public sale without registration under the Securities Act.

     The foregoing restrictions on transferability of Restricted Stock will
terminate as to any particular shares of Restricted Stock when such shares have
been effectively registered under the Securities Act and sold or otherwise
disposed of in accordance with the intended method of disposition by the seller
or sellers of such shares set forth in the registration statement concerning
such shares, or when the legend set forth in Section 2 is removed from the
certificates representing such shares in accordance with the immediately
preceding sentence of this Section 3.  If the transferring Shareholder is able
to demonstrate to the reasonable satisfaction of ASI (and its counsel) that the
provisions of Rule 144(k) of the Securities Act are available to the
transferring Shareholder without limitation, the transferring Shareholder will
be entitled to receive from ASI without expense, a new certificate not bearing
the restrictive legend set forth in Section 2.

     4.   INCIDENTAL REGISTRATION RIGHTS.

          (a)  The Shareholders have incidental registration rights as described
in Section 4(b) (the "Incidental Rights") with respect to the One-Year Shares,
with the following limitations:  (i) the Shareholders will have no Incidental
Rights prior to the first anniversary of the Closing Date, and (ii) after the
first anniversary, but before the second anniversary, of the Closing Date the
Incidental Rights are limited to the One-Year Shares owned by a Shareholder.

          (b)  After the first anniversary of the Closing Date, and before the
second anniversary of the Closing Date, each time ASI proposes to register any
of its equity securities under the Securities Act (other than a registration
effected solely to implement an employee benefit or stock option plan, to sell
shares obtained under any employee benefit or stock-option plan or a transaction
to which Rule 145 or any other similar rule of the Commission under the
Securities Act is applicable, or a registration on any form which is not
available for the registration of Restricted Stock), ASI will give written
notice to the Shareholders of its intention to do so.  Any Shareholder may give
ASI a written request to register all or some of the Restricted Stock in the
registration described in the written notice from ASI, provided that such
written request is given within 20 days after receipt of any such notice from
ASI, with such 

<PAGE>

request stating the number of shares of Restricted Stock to be disposed of 
and the intended method of disposition of such Restricted Stock. Upon receipt 
of such request, ASI will use its best efforts to cause promptly all such 
shares of Restricted Stock intended to be disposed of to be registered under 
the Securities Act so as to permit their sale or other disposition in 
accordance with the intended methods set forth in the request for 
registration; PROVIDED, HOWEVER, that if the registration relates to an 
underwritten offering, (i) the requesting Shareholders' right to have shares 
of Restricted Stock included in the registration will be contingent upon the 
requesting Shareholders agreeing to include such Restricted Stock in the 
offering and entering into an underwriting agreement as provided in Section 
6, and (ii) if the managing underwriter of such offering determines 
reasonably and in good faith in writing that the inclusion of all of the 
shares of Restricted Stock as to which the requesting Shareholders have 
requested registration would adversely affect the offering, the number of 
shares to be registered for the account of such requesting Shareholders will 
be reduced to the extent necessary to reduce the total number of shares to be 
included in such offering to the amount recommended by such managing 
underwriter.  Any reduction under clause (ii) will be made against all 
persons (other than ASI) who have elected to include shares of Common Stock 
in the registration pursuant to the exercise of incidental registration 
rights granted by ASI, in proportion to the number of shares that each had 
been entitled to request, and had requested, ASI to include in the 
registration.  The Incidental Rights under this section apply to a 
registration to be effected for securities to be sold for the account of ASI, 
as well as a registration statement which includes securities to be offered 
for the account of other holders of ASI equity securities.

     5.   PURCHASE IN LIEU OF REGISTRATION.  If the Shareholders exercise
Incidental Rights as to any shares of the Restricted Stock (a "Registration
Notice"), then ASI will have the option (the "Option"), which Option may be
exercised only to the extent not prohibited by Section 7-106-401 of the Colorado
Business Corporation Act, to purchase any or all of such shares, in lieu of
registering them, at the current market price determined as follows: as to each
share of Common Stock, the average of the daily closing prices for the Common
Stock for the 20 consecutive trading days before the day the Registration Notice
was received by ASI.  The closing price for each day will be the last reported
sale price regular way, or, in case no such reported sale takes place on such
day, the reported closing price regular way, in either case on the composite
tape, or if the Common Stock is not quoted on the composite tape, on the
principal United States securities exchange registered under the Securities
Exchange Act of 1934, on which the Common Stock is listed or admitted to
trading, or if it is not listed or admitted to trading on any such exchange, the
closing sale price (or the average of the quoted closing bid and asked prices if
no sale is reported) as reported by the National Association of Securities
Dealers Automated Quotation System ("NASDAQ"), or any comparable system, or if
the Common Stock is not quoted on the NASDAQ, or any comparable system, the
average of the closing bid and asked prices quoted to the public by a person
then making a market in the Common Stock, and if no person is a market maker in
the Common Stock, then the average of the closing bid and asked prices furnished
by any member of the National Association of Securities Dealers, Inc.  ASI may
exercise the Option at any time within 15 days after receiving the Registration
Notice by giving the selling Shareholders written notice of its election to
exercise.  Such notice must specify the number of shares of the Restricted Stock
that ASI elects to purchase, the current market price as determined according to
the formula set forth above, and the date of payment for such shares, 

<PAGE>

which will be within 60 days after ASI's receipt of the Registration Notice.  
On the date fixed for payment in ASI's notice of exercise, the selling 
Shareholders will deliver certificates representing the shares of Restricted 
Stock that ASI has elected to purchase, duly endorsed for transfer to ASI, 
free and clear of liens, claims and encumbrances, to ASI at its principal 
executive offices against payment by ASI of the purchase price for such 
shares.  If ASI elects to purchase less than all of the shares covered by a 
Registration Notice, it will be obligated to register the balance of such 
shares, subject to the provisions of Section 4.

     6.   REGISTRATION PROCEDURES. As to any shares of Restricted Stock that are
subject to a Registration Notice under the Incidental Rights and as to which ASI
does not exercise the Option provided for in Section 5, ASI will:

          (a)  after the expiration of the period within which ASI may exercise
     the Option, prepare and file with the Commission, a registration statement
     with respect to such securities;

          (b)  prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection with such registration statement to comply with the provisions
     of the Securities Act with respect to the disposition of all Restricted
     Stock covered by such registration statement in accordance with the selling
     Shareholders  intended method of disposition set forth in such registration
     statement for such period;

          (c)  furnish to the selling Shareholders and to each underwriter such
     number of copies of the registration statement and the prospectus included
     in the registration statement (including each preliminary prospectus) as
     such persons may reasonably request in order to facilitate the public sale
     or other disposition of Restricted Stock covered by such registration
     statement;

          (d)  use its best efforts to register or qualify Restricted Stock
     covered by such registration statement under the securities or blue sky
     laws of such jurisdictions as the selling Shareholders or, in the case of
     an underwritten public offering, the managing underwriter, reasonably
     requests, if such registrations are required by law;

          (e)  immediately notify the selling Shareholders and each underwriter,
     at any time when a prospectus relating to such registration statement is
     required to be delivered under the Securities Act, of the happening of any
     event as a result of which the prospectus contained in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state any material fact required to be stated in such
     prospectus or necessary to make the statements in such prospectus not
     misleading in light of the circumstances then existing;

          (f)  use its best efforts (if the offering is underwritten) to
     furnish, at the request of the selling Shareholders on the date that
     Restricted Stock is delivered to 

<PAGE>

     the underwriters for sale pursuant to such registration:  (i) an opinion 
     dated such date of counsel representing ASI for the purposes of such 
     registration, addressed to the underwriters and to the ESOP Trustee 
     stating that such registration statement has become effective under the 
     Securities Act and that (A) to the best knowledge of such counsel no 
     stop order suspending the effectiveness of such registration statement 
     has been issued and no proceedings for that purpose have been instituted 
     or are pending or contemplated under the Securities Act, (B) the 
     registration statement, the related prospectus, and each amendment or 
     supplement of each of them, comply as to form in all material respects 
     with the requirements of the Securities Act and the applicable rules and 
     regulations of the Commission under the Securities Act (except that such 
     counsel need express no opinion as to financial statements and other 
     financial and statistical data contained in each of them), and (C) to 
     such other effects as may reasonably be requested by counsel for the 
     underwriters or by the selling Shareholders or their counsel, and (ii) a 
     letter dated such date from the independent public accountants retained 
     by ASI, addressed to the underwriters and to the selling Shareholders, 
     stating that they are independent public accountants within the meaning 
     of the Securities Act and that, in the opinion of such accountant; the 
     financial statements of ASI included in the registration statement or 
     the prospectus, or any amendment or supplement of such statement or 
     prospectus, comply as to form in all material respects with the 
     applicable accounting requirements of the Securities Act, and such 
     letter will additionally cover such other financial matters with respect 
     to the registration in respect of which such letter is being given as 
     such underwriters may reasonably request;

          (g)  make available for inspection by the selling Shareholders and any
     attorney, accountant or other agent retained by any of them, all financial
     and other records, pertinent corporate documents and properties of ASI and
     cause ASI's officers, directors and employees to supply all information
     reasonably requested by the selling Shareholders or any such attorney,
     accountant or agent in connection with such registration statement;

          (h)  as expeditiously as is reasonably practicable, cause all
     Restricted Stock covered by the registration statement to be listed on each
     securities exchange on which similar securities of ASI are then listed; and

          (i)  provide a transfer agent and registrar for all Restricted Stock
     covered by the registration statement not later than the effective date of
     such registration statement.

     ASI will be entitled to control the timing of the registration process in
all respects and may withdraw or terminate any such registration at any time.

     In connection with each registration under this Agreement, the selling
Shareholders will furnish to ASI in writing such information with respect to
themselves and the 

<PAGE>

proposed distribution by them as will be reasonably necessary in order to 
assure compliance with federal and applicable state securities laws.

     In connection with each registration pursuant to Section 4 covering an
underwritten public offering, ASI and the selling Shareholders will enter into a
written agreement with the managing underwriter selected in the manner provided
above in such form and containing such provisions as are customary in the
securities business for such an arrangement between major underwriters and
companies of ASI's size and investment stature; PROVIDED, HOWEVER, that such
agreement will not contain any such provision applicable to ASI or the selling
Shareholders which is inconsistent with the provisions of this Agreement and
provided, further, that the time and place of the closing under said agreement
will be as mutually agreed upon among ASI, such managing underwriter, and the
selling Shareholders.

     7.   EXPENSES.

          (j)  All expenses incurred in complying with Section 4, including,
without limitation, all registration and filing fees, printing expenses, fees
and disbursements of counsel and independent public accountants for ASI, fees of
the Commission and National Association of Securities Dealers, Inc., transfer
taxes and fees of transfer agents and registrars, but excluding any Selling
Expenses and fees and expenses of counsel for the selling Shareholders or any
other expenses of such Shareholders, are referred to as "Registration Expenses".
All underwriting discounts, selling commissions applicable to the sale of the
Restricted Stock, and any customary and reasonable underwriter's expense
allowances expressed on a percentage of the proceeds of the offering, are
referred to as "Selling Expenses".

          (k)  ASI will pay all Registration Expenses in connection with each
registration statement filed pursuant to Section 4.  All Selling Expenses in
connection with any registration statement filed pursuant to Section 4 will be
borne pro rata by the participating Shareholders.

     8.   INDEMNIFICATION.  In the event of a registration of any of the
Restricted Stock under the Securities Act pursuant to Section 4, ASI will
indemnify and hold harmless the selling Shareholders, and each underwriter of
Restricted Stock under the Securities Act and each other person, if any, who
controls the selling Shareholders or any underwriter within the meaning of the
Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which the selling Shareholders or underwriter or controlling person
may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect of such losses,
claims, damages or liabilities) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the
registration statement under which such Restricted Stock was registered, any
preliminary prospectus or final prospectus contained in such registration
statement, or any amendment or supplement of such registration statement, or
arise out of or are based upon the omission or alleged omission to state in such
registration statement or prospectus a material fact required to be therein or
necessary to make the statements therein not misleading, and will reimburse the
selling Shareholders, each such underwriter and each such controlling person for
any legal or other expenses reasonably incurred 

<PAGE>

by them in connection with investigating or defending any such loss, claim, 
damage, liability or action; provided, however that ASI will not be liable in 
any such case if and to the extent that any such loss, claim, damage or 
liability arises out of or is based upon an untrue statement or alleged 
untrue statement or omission or alleged omission so made in conformity with 
information furnished by the selling Shareholders, any underwriter or any 
controlling person in writing specifically for use in such registration 
statement or prospectus.

     If there is a registration of any of the Restricted Stock under the 
Securities Act pursuant to Section 4, the selling Shareholders will indemnify 
and hold harmless ASI and each person, if any, who controls ASI within the 
meaning of the Securities Act, each officer of ASI who signs the registration 
statement, each director of ASI, each underwriter and each person who 
controls any underwriter within the meaning of the Securities Act, against 
all losses, claims, damages or liabilities, joint or several, to which ASI or 
such officer or director or underwriter or controlling person may become 
subject under the Securities Act or otherwise, insofar as such losses, 
claims, damages or liabilities (or actions in respect of such losses, claims, 
damages or liabilities) arise out of or are based upon any untrue statement 
or alleged untrue statement of any material fact contained in the 
registration statement under which such Restricted Stock was registered, any 
preliminary prospectus or final prospectus contained in such registration 
statement or any amendment or supplement of such registration statement, or 
arise out of or are based upon the omission or alleged omission to state in 
such registration statement or prospectus a material fact required to be 
stated therein or necessary to make the statements therein not misleading, 
and will reimburse ASI and each such officer, director, underwriter and 
controlling person for any legal or other expenses reasonably incurred by 
them in connection with investigating or defending any such loss, claim, 
damage, liability or action; provided, however, that the selling Shareholders 
will be liable under this Agreement in any such case if and only to the 
extent that any such loss, claim, damage or liability arises out of or is 
based upon an untrue statement or alleged untrue statement or omission or 
alleged omission made in reliance upon and in conformity with information 
furnished in writing to ASI by the selling Shareholders specifically for use 
in such registration statement or prospectus provided, further, however that 
the liability of the selling Shareholders under this Agreement will be 
limited to the proportion of any such loss, claim, damage, liability or 
expense which is equal to the proportion that the public offering price of 
shares sold by the selling Shareholders under such registration statement 
bears to the total public offering price of all securities sold under such 
registration statement, but not to exceed the proceeds received by the 
selling Shareholders from the sale of the Restricted Stock covered by such 
registration statement.

     Promptly after receipt by an indemnified party under this Agreement of
notice of the commencement of any action, such indemnified party will, if a
claim in respect of such action is to be made against the indemnifying party
under this Agreement, promptly notify the indemnifying party in writing of such
claim but the omission so to notify the indemnifying party will not relieve it
from any liability which it may have to any indemnified party except to the
extent that the indemnifying party is prejudiced by such omission or delay.  In
case any such action is brought against any indemnified party and it notifies
the indemnifying party of the commencement of such action, the indemnifying
party will be entitled to participate in and, to the extent it wishes, to assume
and undertake the defense of such action with counsel reasonably 

<PAGE>

satisfactory to such indemnified party, and, after notice from the 
indemnifying party to such indemnified party of its election so to assume and 
undertake the defense of such action, the indemnifying party will not be 
liable to such indemnified party under this Section 8 for any legal expenses 
subsequently incurred by such indemnified party in connection with the 
defense of such action other than reasonable costs of investigation and of 
liaison with counsel so selected (unless such indemnified party reasonably 
objects to such assumption on the grounds that there are likely to be 
defenses available to it which are different from or in addition to, and are 
in conflict with, the defenses available to such indemnifying party, in which 
event the indemnified party will be reimbursed by the indemnifying party for 
the reasonable expenses incurred in connection with retaining its separate 
legal counsel, but only to the extent of such conflict). The indemnifying 
party will lose its right to defend, contest, litigate and settle a matter if 
it fails to contest such matter diligently.  No matter will be settled by an 
indemnifying party without the prior written consent of the indemnified 
party, unless such settlement contains a full and unconditional release of 
the indemnified party.

     Notwithstanding the foregoing, any indemnified party has the right to 
retain its own counsel in any such action, but the fees and disbursements of 
such counsel will be at the expense of such indemnified party unless (i) the 
indemnifying party fails to retain counsel for the indemnified person as 
aforesaid or (ii) the indemnifying party and such indemnified party mutually 
agree to the retention of such counsel.  The indemnifying party will not, in 
connection with any action or related actions in the same jurisdiction, be 
liable for the fees and disbursements of more than one separate firm 
qualified in such jurisdiction to act as counsel for the indemnified party.  
The indemnifying party will not be liable for any settlement of any 
proceeding effected without its written consent, but if settled with such 
consent or if there is a final judgment for the plaintiff, the indemnifying 
party agrees to indemnify the indemnified party from and against any loss or 
liability by reason of such settlement or judgment.

     If the indemnification provided for in the first two paragraphs of this 
Section 8 is unavailable or insufficient to hold harmless an indemnified 
party under such paragraphs in respect of any losses, claims, damages or 
liabilities or actions in respect of such losses, claims, damages or 
liabilities, then each indemnifying party will in lieu of indemnifying such 
indemnified party contribute to the amount paid or payable by such 
indemnified party as a result of such losses, claims, damages, liabilities or 
actions in such proportion as appropriate to reflect the relative fault of 
ASI, on the one hand, and the underwriters and the selling Shareholders, on 
the other, in connection with the statements or omissions which resulted in 
such losses, claims, damages, liabilities or actions, as well as any other 
relevant equitable considerations. ASI and the Shareholders agree that it 
would not be just and equitable if contributions pursuant to this paragraph 
were determined by pro rata allocation or by any other method of allocation 
which did not take account of the equitable considerations referred to above 
in this paragraph.  Notwithstanding the provisions of this paragraph, no 
Shareholder will be required to contribute any amount in excess of the lesser 
of (i) the proportion that the public offering price of shares sold by such 
Shareholder under such registration statement bears to the total public 
offering price of all securities sold under such registration statement, but 
not to exceed the proceeds received by such Shareholder for the sale of the 
Restricted Stock covered by such registration statement and (ii) the amount 
of any damages which it would have otherwise been required to pay by reason 
of 

<PAGE>

such untrue or alleged untrue statement or omission.  No person guilty of 
fraudulent misrepresentations (within the meaning of Section 11(f) of the 
Securities Act), will be entitled to contribution from any person who is not 
guilty of such fraudulent misrepresentation.

     The indemnification of underwriters provided for in this Section 8 will be
on such other terms and conditions as are at the time customary and reasonably
required by such underwriters.  The indemnification provided for under this
Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party and will survive the transfer of
the shares of Restricted Stock.

     9.   PERMITTED TRANSFEREES.

          (a)  In order to Transfer Restricted Stock to a Permitted Transferee,
the Shareholders will submit the certificates representing the shares to ASI
together with (i) a written agreement satisfactory in form and substance to ASI
signed by the Permitted Transferee agreeing to be bound by all of the terms and
provisions of this Agreement applicable to the Shareholders, (ii) such evidence
as ASI may reasonably request that the proposed transferee is a Permitted
Transferee; (iii) an opinion of counsel reasonably satisfactory to ASI that the
proposed Transfer may be effective without registration under the Securities Act
and any state securities laws.  The certificate issued in the name of the
Permitted Transferee will bear the legend referred to in Section 2.

          (b)  Following any Transfer of Restricted Stock to a Permitted
Transferee, the transferring Shareholder and all of his Permitted Transferees
will be jointly and severally liable for the performance of the obligations of
such Shareholder under this Agreement, and the rights of such Shareholder under
this Agreement will be exercised by a single representative of all holders of
such Shareholder's portion of the Restricted Stock.  As long as a Shareholder is
alive and legally competent and continues to own any share of Restricted Stock,
such Shareholder will be that representative.  Upon the death or incompetency of
such Shareholder, his executor or conservator will appoint a Permitted
Transferee as successor representative.  Upon the Transfer by a Shareholder of
all of his Restricted Stock, if any Permitted Transferee will own Restricted
Stock after the Transfer, such Shareholder will appoint a Permitted Transferee
as successor representative.  If any successor representative appointed by a
Shareholder or his executor or conservator resigns or ceases to own Restricted
Stock, the Permitted Transferees will appoint a successor representative by
majority vote of the shares of Restricted Stock then owned by all Permitted
Transferees.  A Shareholder or other person or persons appointing or electing a
successor representative will give written notice of such election or
appointment to ASI, identifying the successor representative.  ASI will be
entitled to rely without inquiry on the instructions of the representative last
identified to it as provided above and may disregard any contrary claims or
demands by any other holder of such Restricted Stock.

          (c)  After any Transfer to a Permitted Transferee, all provisions of
this Agreement will apply to all shares, transactions or actions of the
Shareholders and all Permitted Transferees in the aggregate. 

     10.  MISCELLANEOUS.

<PAGE>

          (a)  In order to make available to the Shareholders the benefits of
certain rules and regulations of the Commission which may permit the sale of the
shares of Restricted Stock to the public without registration, ASI agrees that,
when required  by law, it will use its best efforts to:  (i) make and keep
public information available, as those terms are understood and defined in Rule
144 of the Commission, at all times; (ii) file with the Commission in a timely
manner all reports and other documents required of ASI under the Securities Act
and the Exchange Act; and (iii) so long as any of the Shareholders own any
shares of Restricted Stock, furnish a Shareholder, promptly after such
Shareholder's request a written statement by ASI as to its compliance with the
reporting requirements of Rule 144.

          (b)  All covenants and agreements contained in this Agreement by or on
behalf of any of the parties to this Agreement will bind and inure to the
benefit of the respective successors and assigns of the parties to this
Agreement whether so expressed or not.

          (c)  All notices, requests, demands, claims, and other communications

     and

               (ii) if to a Shareholder at the address for notice set forth
     opposite such Shareholder's signature below.

Notices will be deemed given three days after mailing if sent by certified mail,
when delivered if sent by courier, and one business day after receipt of
confirmation by person or machine if sent by telecopy or facsimile transmission.
Any party may change the address to which notices, requests, demands, claims and
other communications under this Agreement are to be delivered by giving the
other parties notice in the manner set forth in this Agreement.

          (d)  This Agreement will be governed by and construed in accordance
with the laws of the State of Colorado.

          (e)  Any dispute arising under this Agreement will be resolved in
accordance with Article X (Alternative Dispute Resolution) of the Merger
Agreement.

          (f)  This Agreement constitutes the entire agreement of the parties
with respect to the subject matter of this Agreement and may not be modified or
amended except in writing.

          (g)  This Agreement may be executed in two or more counterparts, each
of which will be deemed an original, but all of which together will constitute
one and the same instrument.

     "COMMON STOCK" means the shares of common stock, no par value, of ASI as
constituted as of the date of this Agreement.

     "ESOP STOCK" means the shares of Common Stock issued to the ESOP pursuant
to the Merger Agreement and any additional shares of Common Stock or other

     "SECURITIES ACT" means the Securities Act of 1933 or any similar federal

     "TRADING DAY" means a day on which shares of the Common Stock are traded on

     2.   RESTRICTIVE LEGEND.  Each certificate representing ESOP Stock until
such legend is removed or such shares are sold in accordance with the other
provisions of this Agreement, will be stamped or otherwise imprinted with a
legend substantially in the following form:

     "THE SHARES EVIDENCED BY THIS CERTIFICATE (A) HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE,
     AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY
     HAVE BEEN REGISTERED UNDER THAT ACT AND ALL APPLICABLE STATE
     SECURITIES LAWS OR EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS
     THEREOF ARE AVAILABLE, AS ESTABLISHED TO THE SATISFACTION OF THE
     COMPANY, BY OPINION OF COUNSEL OR OTHERWISE, AND (B) ARE SUBJECT TO
     CONTRACTUAL RESTRICTIONS ON RESALE AND TRANSFER UNDER AGREEMENTS
     BETWEEN THE HOLDER AND THE COMPANY, COPIES OF WHICH ARE AVAILABLE FOR
     INSPECTION AT THE OFFICES OF THE COMPANY."

     3.   NOTICE OF PROPOSED TRANSFER.  Prior to any proposed transfer of any
ESOP Stock (other than under the circumstances described in Section 4), the ESOP
Trustee will give written notice to ASI of its intention to effect such
transfer.  Each such notice will describe the manner of the proposed transfer
and, if requested by ASI will be accompanied by an opinion of counsel reasonably
satisfactory to ASI to the effect that the proposed transfer of the ESOP Stock
may be effected without registration under the Securities Act and any state
securities laws, at which point such ESOP Stock may be transferred in accordance
with the terms of its notice.  Each certificate of ESOP Stock transferred as
provided above will bear the legend set forth in 

<PAGE>

Section 2, unless (i) such transfer is in accordance with the provisions of 
Rule 144 (or any other rule permitting public sale without registration under 
the Securities Act) or (ii) the opinion of counsel referred to above is to 
the further effect that the transferee and any subsequent transferee would be 
entitled to transfer such securities in a public sale without registration 
under the Securities Act.

     The foregoing restrictions on transferability of ESOP Stock will terminate
as to any particular shares of ESOP Stock when such shares have been effectively
registered under the Securities Act and sold or otherwise disposed of in
accordance with the intended method of disposition by the seller or sellers of
such shares set forth in the registration statement concerning such shares, or
when the legend set forth in Section 2 is removed from the certificates
representing such shares in accordance with the immediately preceding sentence
of this Section 3.  If the ESOP Trustee is able to demonstrate to the reasonable
satisfaction of ASI (and its counsel) that the provisions of Rule 144(k) of the
Securities Act are available to the ESOP without limitation, the ESOP Trustee
will be entitled to receive from ASI without expense, a new certificate not
bearing the restrictive legend set forth in Section 2.

     4.   INCIDENTAL REGISTRATION RIGHTS.

          (a)  The ESOP has incidental registration rights as described in
     Section 4(b) (the "Incidental Rights") with respect to all of the shares of
     ESOP Stock, after the first anniversary of the Closing Date, and before the
     second anniversary of the Closing Date.

          (b)  After the first anniversary of the Closing Date, and before 
     the second anniversary of the Closing Date, each time ASI proposes to 
     register any of its equity securities under the Securities Act (other 
     than a registration effected solely to implement an employee benefit or 
     stock option plan, to sell shares obtained under any employee benefit or 
     stock-option plan or a transaction to which Rule 145 or any other 
     similar rule of the Commission under the Securities Act is applicable, 
     or a registration on any form which is not available for the 
     registration of ESOP Stock), ASI will give written notice to the ESOP 
     Trustee of its intention to do so. The ESOP Trustee may give ASI a 
     written request to register all or some of the ESOP Stock in the 
     registration described in the written notice from ASI, provided that 
     such written request is given within 20 days after receipt of any such 
     notice from ASI, with such request stating the number of shares of ESOP 
     Stock to be disposed of and the intended method of disposition of such 
     ESOP Stock.  Upon receipt of such request, ASI will use its best efforts 
     to cause promptly all such shares of ESOP Stock intended to be disposed 
     of to be registered under the Securities Act so as to permit its sale or 
     other disposition in accordance with the intended methods set forth in 
     the request for registration; PROVIDED, HOWEVER, that if the 
     registration relates to an underwritten offering, (i) the ESOP Trustee's 
     right to have shares of ESOP Stock included in the registration will be 
     contingent upon the ESOP Trustee agreeing to include such ESOP Stock in 
     the offering and entering into an underwriting agreement as 

<PAGE>

     provided in Section 6, and (ii) if the managing underwriter of such 
     offering determines reasonably and in good faith in writing that the 
     inclusion of all of the shares of ESOP Stock as to which the ESOP 
     Trustee has requested registration would adversely affect the offering, 
     the number of shares to be registered will be reduced to the extent 
     necessary to reduce the total number of shares to be included in such 
     offering to the amount recommended by such managing underwriter.  Any 
     reduction under clause (ii) will be made against all persons (other than 
     ASI) who have elected to include shares of Common Stock in the 
     registration pursuant to the exercise of incidental registration rights 
     granted by ASI, in proportion to the number of shares that each had been 
     entitled to request, and had requested, ASI to include in the 
     registration.  The Incidental Rights under this section apply to a 
     registration to be effected for securities to be sold for the account of 
     ASI, as well as a registration statement which includes securities to be 
     offered for the account of other holders of ASI equity securities.

     5.   PURCHASE IN LIEU OF REGISTRATION.  If the ESOP Trustee exercises the
Incidental Rights as to any shares of the ESOP Stock (a "Registration Notice"),
then ASI will have the option (the "Option"), which Option may be exercised only
to the extent not prohibited by Section 7-106-401 of the Colorado Business
Corporation Act, to purchase any or all of such shares, in lieu of registering
them, at the current market price determined as follows: as to each share of
Common Stock, the closing price on the date that is three Trading Days after the
Exercise Notice (as defined below) is given will be the last reported sale price
regular way, or, in case no such reported sale takes place on such day, the
reported closing price regular way, in either case on the composite tape, or if
the Common Stock is not quoted on the composite tape, on the principal United
States securities exchange registered under the Securities Exchange Act of 1934,
on which the Common Stock is listed or admitted to trading, or if it is not
listed or admitted to trading on any such exchange, the closing sale price (or
the average of the quoted closing bid and asked prices if no sale is reported)
as reported by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ"), or any comparable system, or if the Common Stock is
not quoted on the NASDAQ, or any comparable system, the average of the closing
bid and asked prices quoted to the public by a person then making a market in
the Common Stock, and if no person is a market maker in the Common Stock, then
the average of the closing bid and asked prices furnished by any member of the
National Association of Securities Dealers, Inc.  ASI may exercise the Option at
any time within 15 days after receiving the Registration Notice by giving the
ESOP Trustee written notice of its election to exercise (the "Exercise Notice").
The Exercise Notice must specify the number of shares of ESOP Stock that ASI
elects to purchase, and the date of payment for the Shares, which will be the
fourth Trading Day after the receipt of the Exercise Notice.  On such date, the
ESOP Trustee will deliver certificates representing the shares of ESOP Stock
that ASI has elected to purchase, duly endorsed for transfer to ASI, free and
clear of liens, claims and encumbrances, to ASI at its principal executive
offices against payment by ASI of the purchase price, as determined according to
the formula set forth above, for such shares.  If ASI elects to purchase less
than all of the shares covered by a Registration Notice, it will be obligated to
register the balance of such shares, subject to the provisions of Section 4.

<PAGE>

     6.   REGISTRATION PROCEDURES. As to any shares of ESOP Stock that are
subject to a Registration Notice under the Incidental Rights and as to which ASI
does not exercise the Option provided for in Section 5, ASI will:

          (a)  after the expiration of the period within which ASI may exercise
     the Option, prepare and file with the Commission, a registration statement
     with respect to such securities;

          (b)  prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection with such registration statement to comply with the provisions
     of the Securities Act with respect to the disposition of all ESOP Stock
     covered by such registration statement in accordance with the ESOP
     Trustee's intended method of disposition set forth in such registration
     statement for such period;

          (c)  furnish to the ESOP Trustee and to each underwriter such number
     of copies of the registration statement and the prospectus included in the
     registration statement (including each preliminary prospectus) as such
     persons may reasonably request in order to facilitate the public sale or
     other disposition of ESOP Stock covered by such registration statement;

          (d)  use its best efforts to register or qualify ESOP Stock covered by
     such registration statement under the securities or blue sky laws of such
     jurisdictions as the ESOP Trustee or, in the case of an underwritten public
     offering, the managing underwriter, reasonably requests, if such
     registrations are required by law;

          (e)  immediately notify the ESOP Trustee and each underwriter, at any
     time when a prospectus relating to such registration statement is required
     to be delivered under the Securities Act, of the happening of any event as
     a result of which the prospectus contained in such registration statement,
     as then in effect, includes an untrue statement of a material fact or omits
     to state any material fact required to be stated in such prospectus or
     necessary to make the statements in such prospectus not misleading in light
     of the circumstances then existing;

          (f)  use its best efforts (if the offering is underwritten) to
     furnish, at the request of the ESOP Trustee on the date that ESOP Stock is
     delivered to the underwriters for sale pursuant to such registration: 
     (i) an opinion dated such date of counsel representing ASI for the purposes
     of such registration, addressed to the underwriters and to the ESOP Trustee
     stating that such registration statement has become effective under the
     Securities Act and that (A) to the best knowledge of such counsel no stop
     order suspending the effectiveness of such registration statement has been
     issued and no proceedings for that purpose have been instituted or are
     pending or contemplated under the Securities Act, (B) the registration
     statement, the related prospectus, and each amendment or supplement 

<PAGE>

     of each of them, comply as to form in all material respects with the 
     requirements of the Securities Act and the applicable rules and regulations
     of the Commission under the Securities Act (except that such counsel need 
     express no opinion as to financial statements and other financial and 
     statistical data contained in each of them), and (C) to such other effects 
     as may reasonably be requested by counsel for the underwriters or by the 
     ESOP Trustee or its counsel, and (ii) a letter dated such date from the
     independent public accountants retained by ASI, addressed to the
     underwriters and to the ESOP Trustee, stating that they are independent
     public accountants within the meaning of the Securities Act and that, in
     the opinion of such accountant; the financial statements of ASI included in
     the registration statement or the prospectus, or any amendment or
     supplement of such statement or prospectus, comply as to form in all
     material respects with the applicable accounting requirements of the
     Securities Act, and such letter will additionally cover such other
     financial matters with respect to the registration in respect of which such
     letter is being given as such underwriters may reasonably request;

          (g)  make available for inspection by the ESOP Trustee and any
     attorney, accountant or other agent retained by him, all financial and
     other records, pertinent corporate documents and properties of ASI and
     cause ASI's officers, directors and employees to supply all information
     reasonably requested by the ESOP Trustee or any such attorney, accountant
     or agent in connection with such registration statement;

          (h)  as expeditiously as is reasonably practicable, cause all ESOP
     Stock covered by the registration statement to be listed on each securities
     exchange on which similar securities of ASI are then listed; and

          (i)  provide a transfer agent and registrar for all ESOP Stock covered
     by the registration statement not later than the effective date of such
     registration statement.

     ASI will be entitled to control the timing of the registration process in
all respects and may withdraw or terminate any such registration at any time.

     In connection with each registration under this Agreement, the ESOP Trustee
will furnish to ASI in writing such information with respect to the ESOP and the
proposed distribution by it as will be reasonably necessary in order to assure
compliance with federal and applicable state securities laws.

     In connection with each registration pursuant to Section 4 covering an
underwritten public offering, ASI and the ESOP Trustee will enter into a written
agreement with the managing underwriter selected in the manner provided above in
such form and containing such provisions as are customary in the securities
business for such an arrangement between major underwriters and companies of
ASI's size and investment stature; PROVIDED, HOWEVER, that such agreement will
not contain any such provision applicable to ASI or the ESOP which is

<PAGE>

inconsistent with the provisions of this Agreement and provided, further, that
the time and place of the closing under said agreement will be as mutually
agreed upon among ASI, such managing underwriter, and the ESOP Trustee.

     7.   EXPENSES.

          (a)  All expenses incurred in complying with Section 4, including,
     without limitation, all registration and filing fees, printing expenses,
     fees and disbursements of counsel and independent public accountants for
     ASI, fees of the Commission and National Association of Securities Dealers,
     Inc., transfer taxes and fees of transfer agents and registrars, but
     excluding any Selling Expenses and fees and expenses of counsel for the
     ESOP or any other expenses of the ESOP, are referred to as "Registration
     Expenses".  All underwriting discounts, selling commissions applicable to
     the sale of ESOP Stock, and any customary and reasonable underwriter's
     expense allowances expressed on a percentage of the proceeds of the
     offering, are referred to as "Selling Expenses".

          (b)  ASI will pay all Registration Expenses in connection with each
     registration statement filed pursuant to Section 4.  All Selling Expenses
     in connection with any registration statement filed pursuant to Section 4
     will be borne by the ESOP.

     8.   INDEMNIFICATION.  In the event of a registration of any of the ESOP
Stock under the Securities Act pursuant to Section 4, ASI will indemnify and
hold harmless the ESOP, and each underwriter of ESOP Stock under the Securities
Act and each other person, if any, who controls the ESOP or any underwriter
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, to which the ESOP or underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect of such losses,
claims, damages or liabilities) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the
registration statement under which such ESOP Stock was registered, any
preliminary prospectus or final prospectus contained in such registration
statement, or any amendment or supplement of such registration statement, or
arise out of or are based upon the omission or alleged omission to state in such
registration statement or prospectus a material fact required to be therein or
necessary to make the statements therein not misleading, and will reimburse the
ESOP, each such underwriter and each such controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER
that ASI will not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by the ESOP, any underwriter or any
controlling person in writing specifically for use in such registration
statement or prospectus.

     In the event of a registration of any ESOP Stock under the Securities Act
pursuant to Section 4, the ESOP will indemnify and hold harmless ASI and each
person, if any, who 

<PAGE>

controls ASI within the meaning of the Securities Act, each officer of 
ASI who signs the registration statement, each director of ASI, each 
underwriter and each person who controls any underwriter within the 
meaning of the Securities Act, against all losses, claims, damages or 
liabilities, joint or several, to which ASI or such officer or director 
or underwriter or controlling person may become subject under the 
Securities Act or otherwise, insofar as such losses, claims, damages or 
liabilities (or actions in respect of such losses, claims, damages or 
liabilities) arise out of or are based upon any untrue statement or 
alleged untrue statement of any material fact contained in the 
registration statement under which such ESOP Stock was registered, any 
preliminary prospectus or final prospectus contained in such 
registration statement or any amendment or supplement of such 
registration statement, or arise out of or are based upon the omission 
or alleged omission to state in such registration statement or 
prospectus a material fact required to be stated therein or necessary to 
make the statements therein not misleading, and will reimburse ASI and 
each such officer, director, underwriter and controlling person for any 
legal or other expenses reasonably incurred by them in connection with 
investigating or defending any such loss, claim, damage, liability or 
action; PROVIDED, HOWEVER, that the ESOP will be liable under this 
Agreement in any such case if and only to the extent that any such loss, 
claim, damage or liability arises out of or is based upon an untrue 
statement or alleged untrue statement or omission or alleged omission 
made in reliance upon and in conformity with information furnished in 
writing to ASI by the ESOP specifically for use in such registration 
statement or prospectus provided, further, however that the liability of 
the ESOP under this Agreement will be limited to the proportion of any 
such loss, claim, damage, liability or expense which is equal to the 
proportion that the public offering price of shares sold by the ESOP 
under such registration statement bears to the total public offering 
price of all securities sold under such registration statement, but not 
to exceed the proceeds received by the ESOP from the sale of the ESOP 
Stock covered by such registration statement.

     Promptly after receipt by an indemnified party under this Agreement of
notice of the commencement of any action, such indemnified party will, if a
claim in respect of such action is to be made against the indemnifying party
under this Agreement, promptly notify the indemnifying party in writing of such
claim but the omission so to notify the indemnifying party will not relieve it
from any liability which it may have to any indemnified party except to the
extent that the indemnifying party is prejudiced by such omission or delay.  In
case any such action is brought against any indemnified party and it notifies
the indemnifying party of the commencement of such action, the indemnifying
party will be entitled to participate in and, to the extent it wishes, to assume
and undertake the defense of such action with counsel reasonably satisfactory to
such indemnified party, and, after notice from the indemnifying party to such
indemnified party of its election so to assume and undertake the defense of such
action, the indemnifying party will not be liable to such indemnified party
under this Section 8 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense of such action other than
reasonable costs of investigation and of liaison with counsel so selected
(unless such indemnified party reasonably objects to such assumption on the
grounds that there are likely to be defenses available to it which are different
from or in addition to, and are in conflict with, the defenses available to such
indemnifying party, in which event the indemnified party will be reimbursed by
the indemnifying party for the reasonable expenses incurred in connection with
retaining its separate legal counsel, but only to the extent of such conflict). 
The indemnifying 

<PAGE>

party will lose its right to defend, contest, litigate and settle a 
matter if it fails to contest such matter diligently.  No matter will be 
settled by an indemnifying party without the prior written consent of 
the indemnified party, unless such settlement contains a full and 
unconditional release of the indemnified party.

     Notwithstanding the foregoing, any indemnified party has the right to
retain its own counsel in any such action, but the fees and disbursements of
such counsel will be at the expense of such indemnified party unless (i) the
indemnifying party fails to retain counsel for the indemnified person as
aforesaid or (ii) the indemnifying party and such indemnified party mutually
agree to the retention of such counsel.  The indemnifying party will not, in
connection with any action or related actions in the same jurisdiction, be
liable for the fees and disbursements of more than one separate firm qualified
in such jurisdiction to act as counsel for the indemnified party.  The
indemnifying party will not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there is a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment.

     If the indemnification provided for in the first two paragraphs of this
Section 8 is unavailable or insufficient to hold harmless an indemnified party
under such paragraphs in respect of any losses, claims, damages or liabilities
or actions in respect of such losses, claims, damages or liabilities, then each
indemnifying party will in lieu of indemnifying such indemnified party
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or actions in such proportion as
appropriate to reflect the relative fault of ASI, on the one hand, and the
underwriters and the ESOP, on the other, in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
actions, as well as any other relevant equitable considerations.  ASI and the
ESOP agree that it would not be just and equitable if contributions pursuant to
this paragraph were determined by pro rata allocation or by any other method of
allocation which did not take account of the equitable considerations referred
to above in this paragraph.  Notwithstanding the provisions of this paragraph,
the ESOP will not be required to contribute any amount in excess of the lesser
of (i) the proportion that the public offering price of shares sold by the ESOP
under such registration statement bears to the total public offering price of
all securities sold under such registration statement, but not to exceed the
proceeds received by the ESOP for the sale of ESOP Stock covered by such
registration statement and (ii) the amount of any damages which it would have
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission.  No person guilty of fraudulent misrepresentations
(within the meaning of Section 11(f) of the Securities Act), will be entitled to
contribution from any person who is not guilty of such fraudulent
misrepresentation.

     The indemnification of underwriters provided for in this Section 8 will be
on such other terms and conditions as are at the time customary and reasonably
required by such underwriters.  The indemnification provided for under this
Agreement will remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party and will survive the transfer of
the shares of ESOP Stock.

     9.   MISCELLANEOUS.

<PAGE>

     rules and regulations of the Commission which may permit the sale of the
     shares of ESOP Stock to the public without registration, ASI agrees that,
     when required  by law, it will use its best efforts to:  (i) make and keep

     Agreement whether so expressed or not, except that the benefits accorded by
     this Agreement will cease to apply to any shares of the ESOP Stock that are
     transferred or distributed by the ESOP.

     under this Agreement will be in writing.  Any notice, request, demand,

<PAGE>
                                  LOCK-UP AGREEMENT


          This Lock-Up Agreement (this "Agreement") is made as of June 26, 
1998, by and among the Cartotech, Inc. Employee Stock Ownership and 401(k) 
Trust (the "ESOP"), The Epner Family Limited Partnership (the "Epner

collectively, the "Shareholders"), and Analytical Surveys, Inc., a Colorado 
corporation (the "Company").  Any transferee of a Shareholder that is a 
Permitted Transferee (as defined below) of such Shareholder will for all 
purposes of this Agreement be deemed a Shareholder.

                                       RECITALS

     A.   The Company and Surveys Holdings, Inc. ("Holdings") on the one 
hand, and the Shareholders on the other hand, have entered into an Agreement 
and Plan of Merger dated as of June 11, 1998 (the "Merger Agreement") 
pursuant to which Cartotech, Inc. ("Cartotech") will merge with and into 
Holdings, and the Shareholders as the sole shareholders of Cartotech, will 
receive cash and shares of Company common stock (the "Shares").   Pursuant to 
an Escrow Agreement dated June 26, 1998 between the Company, the 
Shareholders, and Bank One, Colorado, N.A., the Company will transfer a 
portion of the cash and Shares directly into escrow.  This Agreement is being 
executed in conjunction with Registration Rights Agreements between the 
Company and the Epner Partnership, the Braverman Partnership and Naumann (the 
"Non-ESOP Shareholders"), and between the Company and the ESOP (the 
"Registration Rights Agreements").

     B.   The Shareholders own the Shares as follows:

<TABLE>
<CAPTION>

     Shareholder                        Number of Shares
     -----------                        ----------------
     <S>                                <C>
     The ESOP                           123,321 shares
     The Epner Partnership              101,398 shares
     The Braverman Partnership          101,398 shares
     Naumann                             28,050 shares
</TABLE>

     C.   The parties desire to limit the transfer of the Shares in the 
manner set forth in this Agreement.  

                                      AGREEMENT
     The parties agree as follows:

     1.   RESTRICTIONS ON TRANSFER.  

          (a)  From the date of this Agreement to, and including, June 26, 
1999, except as expressly provided in this Agreement, no Shareholder may 
transfer any of the Shares or any interest in the Shares.  

<PAGE>

          (b)  From June 27, 1999, to, and including, June 26, 2000, each of 
the Non-ESOP Shareholders may transfer up to 50% of the Shares (the "One-Year 
Shares") held by it or him, subject to the provisions of Section 3.  In 
addition, any or all of the One-Year Shares may be sold pursuant to the 
Registration Rights Agreement to which the Non-ESOP Shareholders are a party.

          (c)  After June 26, 2000, each of the Non-ESOP Shareholders may 
transfer the remainder of the Shares held by it or him, without restriction 
under this Agreement, but any such transfer will remain subject to the 
requirements of state and federal securities laws. 

          (d)  After June 26, 1999, and before June 27, 2000, the ESOP may 
transfer all of the Shares held by it, subject to the provisions of Section 3.

          (e)  After June 26, 2000, the ESOP may transfer any of the Shares, 
without restriction under this Agreement, but any such transfer will remain 
subject to the requirements of state and federal securities laws.          

          (f)  For purposes of this Agreement, "transfer" includes any sale, 
gift, pledge, or other disposition, by voluntary act of a Shareholder or by 
operation of law, as a result of which any person acquires or obtains a right 
to acquire any interest in or rights in respect of the Shares. 

     2.   TRANSFERS TO PERMITTED TRANSFEREES.

          (a)  A Shareholder may transfer any or all of its or his Shares to 
a "Permitted Transferee."  For purposes of this Agreement, "Permitted 
Transferee" means (i) as to the Non-ESOP Shareholders, any trusts or other 
entities created for the exclusive benefit of, or beneficially owned 
exclusively by, a Shareholder; (ii) as to the ESOP, any participant or 
beneficiary of the ESOP; and (iii) as to any Shareholder, a bona fide pledgee 
of Shares.

          (b)  A transfer to a Permitted Transferee is not effective until 
such Permitted Transferee executes and delivers to the Company a document in 
the form of EXHIBIT A to this Agreement by which such Permitted Transferee 
agrees to be bound by the terms of this Agreement.

     3.   SALE VOLUME LIMITATIONS.  During the periods described in Section 
1(b) and 1(d), with respect to each Shareholder, except for sales by such 
Shareholder to a Permitted Transferee of such Shareholder, and including any 
sales of Shares by a Permitted Transferee of such Shareholder other than the 
ESOP (as to whom the volume limitations of this Section 3 will be calculated 
separately as to each such Permitted Transferee), the number of Shares sold 
by a Shareholder in any 90 day period may not exceed the greater of the 
following:

          (a)  one percent of the shares of common stock of the Company 
outstanding as shown by the most recent report or statement published by the 
Company; or


                                        -2-

<PAGE>

          (b)  the average weekly reported volume of trading of common stock 
of the Company on all national securities exchanges and/or reported through 
the automated quotation system of a registered securities association during 
the four calendar weeks preceding the date of the sale of the Shares (the 
"Sale Date"); or
  
          (c)  the average weekly reported volume of trading of common stock 
of the Company reported through the consolidated transaction reporting 
system, contemplated by Rule 11Aa3-1 under the Securities Exchange Act of 
1934, as amended, during the four calendar weeks preceding the Sale Date.

     4.   ENDORSEMENT ON STOCK CERTIFICATES.  All stock certificates 
representing Shares will bear the following legend:

     "THE SHARES EVIDENCED BY THIS CERTIFICATE (A) HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE,
     AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY
     HAVE BEEN REGISTERED UNDER THAT ACT AND ALL APPLICABLE STATE
     SECURITIES LAWS OR EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS
     THEREOF ARE AVAILABLE, AS ESTABLISHED TO THE SATISFACTION OF THE
     COMPANY, BY OPINION OF COUNSEL OR OTHERWISE, AND (B) ARE SUBJECT TO
     CONTRACTUAL RESTRICTIONS ON RESALE AND TRANSFER UNDER AGREEMENTS
     BETWEEN THE HOLDER AND THE COMPANY, COPIES OF WHICH ARE AVAILABLE FOR
     INSPECTION AT THE OFFICES OF THE COMPANY."

     5.   SALE OF ASSETS, REDEMPTION OR LIQUIDATION.  Nothing contained in 
this Agreement will limit the Company's ability, in accordance with 
applicable law, to sell or otherwise dispose of all or substantially all of 
its assets, to redeem all or any part of the stock held by any Shareholder, 
or to liquidate, either partially or completely.

     6.   NOTICES.  All notices, requests, demands, claims, and other 
communications under this Agreement will be in writing.  Any notice, request, 
demand, claim, or other communication under this Agreement will be deemed 
duly given only if it is sent by registered or certified mail, return receipt
