question so that Buyer would not in effect acquire the full benefit of all such
rights, Seller, to the maximum extent permitted by law and the asset to be
assigned, shall cooperate with Buyer, as Buyer may reasonably request, in any
reasonable arrangement designed to provide Buyer the benefits and use of such
asset, including (i) entering into subleases, subcontracts, sale and leasebacks,
use and service agreements or other contractual arrangements which will provide
such benefits and use to Buyer's reasonable satisfaction, and (ii) enforcing for
the benefit of Buyer (at Buyer's expense) any and all rights of Seller in
respect of such asset; provided that Buyer shall not be required to accept or
enter into, as a substitute for performance by Seller under this Agreement, any
arrangement which would impose any additional cost, expense or liability on
Buyer other than that which would have been incurred by Buyer if an asset had
been assigned or would deprive Buyer of any benefits or profits contemplated by
this Agreement.

          (c)  Without limiting any provision of paragraph (b) above, in
connection with the transactions contemplated hereby, Buyer at its option may
execute novations in such form as may reasonably be required by the other
parties to the contracts described above, in which event Buyer shall indemnify
Seller against all Losses Seller may incur

     (iii) the value (at $13.25 per share) of any ABI Shares delivered to Seller

     (iv) the amount of any cash payments previously made by Seller to Buyer (or
     to the Escrow Agent) under Section 3.3(d)(2) or (d)(3) and (e)(1) minus (v)
     the value (at $13.25 per share) of any ABI Shares returned to Buyer (or to

     Purchase Price is negative, the Earned Amount means 100% of the Adjusted

               (6)  "Estimated Annual Net Revenue" means (i) with respect to the
     calculation to be made on the first Determination Date, the estimate of

          (b)  Annual Net Revenue Adjustments. Promptly following the
determination of the Annual Net Revenue on each Determination Date:

                 (i)  If such Annual Net Revenue exceeds the Estimated Annual
     Net Revenue, then the Last Adjusted Purchase Price shall be increased by an
     amount equal to 2.2 times such excess; and

                 (ii) If the Estimated Annual Net Revenue exceeds such Annual
     Net Revenue, then the Last Adjusted Purchase Price shall be decreased by an
     amount equal to 2.2 times such excess.

          (c)  Closing Deficit Adjustments. Promptly following the determination
of the Closing Deficit Amount on each Determination Date:

                 (i)  If the Estimated Closing Deficit Amount exceeds such
     Closing Deficit Amount, then the Last Adjusted Purchase Price shall be
     increased by an amount equal to such excess; and

                                      17
<PAGE>
 
          (ii)   If such Closing Deficit Amount exceeds the Estimated Closing
     Deficit Amount, then the Last Adjusted Purchase Price shall be decreased by
     an amount equal to such excess.

          (d)    Payments.  On each Payment Date:

                 (1)  If the Earned Amount exceeds the Amount Advanced to Seller
     (each as determined on the Determination Date immediately preceding such
     Payment Date), then Buyer and Seller (or the Shareholders) shall mutually
     instruct the Escrow Agent in writing to disburse to Seller (or the
     Shareholders), out of the funds held in escrow, an amount equal to the
     Earned Amount minus the Amount Advanced to Seller. To the extent the amount
     held in escrow is insufficient to make the foregoing payment as a result of
     disbursements made to Seller (or the Shareholders) pursuant to Section
     3.3(d)(1) or as a result of the Adjusted Purchase Price increasing above
     $17,145,000, Buyer shall pay such amount to Seller (or the Shareholders).

                 (2)  If the Amount Advanced to Seller exceeds the Earned Amount
     (each as determined on the Determination Date immediately preceding such
     Payment Date), then Seller (or the Shareholders) shall pay to the Escrow
     Agent, to be held in accordance with the Escrow Agreement, an amount equal
     to the Amount Advanced to Seller minus the Earned Amount.

                 (3)  On the third and fourth Payment Dates, if the Amount
     Advanced by Buyer exceeds the Earned Amount, then Buyer and Seller (or the
     Shareholders) shall mutually instruct the Escrow Agent in writing to
     disburse to Buyer, out of the funds held in escrow, an amount equal to the
     Amount Advanced by Buyer minus the Earned Amount. To the extent the amount
     held in escrow is insufficient to make the foregoing payment to Buyer for
     any reason other than insolvency or defalcation of the Escrow Agent, Seller
     (or the Shareholders) shall pay such amount to Buyer.

          (e)    Form of Payments. Any payment required to be made as a result
                 of an adjustment to the Purchase Price shall be made:

                 (1)  In cash, to the extent the Adjusted Purchase Price is
     greater than or equal to $5,220,000; and

                 (2)  In shares of ABI Common Stock (valued at $13.25 per share
     solely for this purpose), to the extent the Adjusted Purchase Price is less
     than $5,220,000 up to a negative $2,730,000.

                                      18
<PAGE>
 
For example, if on a Determination Date, the Earned Amount is $4,220,000 and the
Advanced Amount is $6,220,000, then the payment required to be made by Seller to
Buyer would consist of $1,000,000 in cash and 75,472 shares of ABI Common Stock
($1,000,000/$13.25 per share). For illustrative purposes, additional examples of
the calculations and adjustments required to be made under this Section 3.3 are
set forth on Schedule 3.3(e).

     3.4  CALCULATION OF POST-CLOSING PAYMENTS.

          (a)  Within 10 days after each Determination Date, the ABI Parties
shall cause their independent public accounting firm, Coopers & Lybrand, to
prepare and deliver to the Selling Parties a statement (the "Closing Statement")
which includes (i) such accounting firm's calculation of Annual Net Revenue and
(ii) a balance sheet which sets forth the assets and liabilities of the Business
(excluding the Excluded Assets and Excluded Liabilities) as of the Effective
Date and includes such accounting firm's calculation of the Closing Deficit
Amount. The Closing Statement Sheet shall be prepared, and the Annual Net
Revenue and Closing Deficit Amount shall be calculated, in accordance with GAAP
consistent with the principles applied in preparing the Most Recent Balance
Sheet (except as set forth on Schedule 3.4(a)). In connection with the
preparation of the Closing Statement on each Determination Date, the ABI Parties
shall make available to the Selling Parties all relevant books and records and
any work papers (including those of the ABI Parties' accountants) relating to
the Closing Statement and all other items reasonably requested by the Selling
Parties. The provisions of paragraphs (b) through (f) of this Section 3.4 shall
apply only with respect to the Closing Statement prepared following the third
and fourth Determination Dates.

          (b)  Within 60 days after the delivery by the ABI Parties of the
Closing Statement, the Selling Parties and their representatives and accountants
shall have the right to review the Closing Statement and the calculations of the
Annual Net Revenue and the Closing Deficit Amount included therein. If the
Selling Parties object to the manner in which the Closing Statement has been
prepared, or to the calculation of the Annual Net Revenue or the Closing Deficit
Amount, the Selling Parties shall deliver written notice (the "Dispute Notice")
to the ABI Parties setting forth in reasonable detail a description of the basis
of the Selling Parties' objection and the adjustments to the Closing Statement
and the calculation of the Annual Net Revenue and the Closing Deficit Amount
that the Selling Parties believe should be made.

          (c)  Within 30 days after the ABI Parties' receipt of the Dispute
Notice, the ABI Parties and their accountants shall review the Dispute Notice
and deliver a written response to the Selling Parties (the "Response")
indicating whether and the extent
                                      19
<PAGE>
 
to which the ABI Parties agree or disagree with the objections set forth in the
Dispute Notice.

          (d)  During a period of 30 days after the Selling Parties' receipt of
the Response, the ABI Parties and the Selling Parties shall attempt in good
faith to resolve in writing any such disputed items, and any such resolution
will be conclusive and binding upon the parties. If the parties are unable to
reach an agreement with respect to any disputed item during such 30-day period,
the parties shall, promptly after the expiration of such period, submit all
unresolved disputes to a nationally recognized independent accounting firm
mutually agreeable to the parties (the "CPA Firm"). If the parties cannot agree
on the selection of the independent accounting firm to act as the CPA Firm,
either party may request the American Arbitration Association to appoint such a
firm, and such appointment shall be conclusive and binding on the parties.
Promptly, but no later than 30 days after its acceptance of its appointment, the
CPA Firm shall determine, only with respect to the remaining items in dispute so
submitted, whether and to what extent, if any, the Closing Statement and the
Annual Net Revenue and the Closing Deficit Amount derived therefrom require
adjustment. The parties shall instruct the CPA Firm to deliver its written
report as to the resolution of all disputes no later than 30 days after the
disputes are submitted to the CPA Firm. The ABI Parties and the Selling Parties
shall make available to the CPA Firm all relevant books and records and any work
papers (including those of the parties' respective accountants) relating to the
Closing Statement and all other items reasonably requested by the CPA Firm. The
CPA Firm shall have exclusive jurisdiction over, and resort to the CPA Firm as
provided in this paragraph (d) shall be the sole recourse and remedy of the
parties against one another or any other person with respect to, any disputes
arising out of or relating to the Closing Statement; and the CPA Firm's
determination shall be conclusive and binding on the parties and shall be
enforceable in a court of law.

          (e)  The ABI Parties and the Selling Parties shall bear the fees and
expenses of their respective accountants and other representatives. The fees and
expenses of the CPA Firm shall be borne equally by the ABI Parties, on the one
hand, and the Selling Parties, on the other hand.

          (f)  The "Final Closing Statement" shall be (i) the Closing Statement
prepared in connection with the calculation to be made on the final
Determination Date, if (x) no Dispute Notice is delivered to the ABI Parties in
the 60-day period referred to in Section 3.4(b) above, or (y) the ABI Parties
and the Selling Parties so agree; (ii) the Closing Statement prepared in
connection with the calculations to be made on the final Determination Date, as
adjusted in accordance with the Dispute Notice, if the ABI Parties agree with
the Dispute Notice or fail to respond to the Dispute Notice within the 30-day
period referred to in Section 3.4(c) above; or (iii) the Closing Statement
prepared on the
               
                                      20
<PAGE>
 
final Determination Date, as adjusted by either (x) the mutual agreement of the
ABI Parties and the Selling Parties or (y) the CPA Firm.

     3.5  LEGEND.  The certificates representing the ABI Shares shall be
imprinted with the following legend:

          The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended, or any state
          securities law, and may not be sold, transferred or otherwise disposed
          of unless (i) a registration statement under such Act is then in
          effect with respect thereto and the transfer is in compliance with
          applicable state securities laws, or (ii) the issuer has been
          furnished with an opinion of counsel, in form and substance reasonably
          satisfactory to the issuer, that no such registration is required. The
          securities represented by this certificate are subject to additional
          restrictions on transfer set forth in the Registration Rights
          Agreement dated September 10, 1996, a copy of which may be obtained

     3.6  LIQUIDATION OF SELLER.  The ABI Parties acknowledge that Seller may
cease to do business, reorganize, recapitalize, distribute assets to the
Shareholders, liquidate, and/or dissolve at any time after the Closing. The ABI
Parties agree that, in connection with any such reorganization,
recapitalization, distribution, liquidation or dissolution, Seller's rights
under this Agreement and Seller's right, title and interest in and to the ABI
Shares or the Note (or any proceeds of any of the foregoing) may be assigned (in
whole or in part) by Seller to one or more of the Shareholders, and the ABI
Parties hereby consent to any such assignment.

     3.7  PRE-CLOSING RECEIVABLES.  Buyer and Parent will use their best efforts
to bill and collect, as expeditiously as possible, all outstanding accounts
receivable and other accrued receivables of the Business outstanding as of the
Effective Date (the "Pre-Closing Receivables") in accordance with Parent's prior
commercial practices. Commencing in January 1997, and continuing at least once
each month thereafter until September 1998, Buyer shall meet with Seller to
review the status and amount of all collected and uncollected Pre-Closing
Receivables. With respect to any Pre-Closing Receivable which Buyer ceases to
use its best efforts to collect or which has been outstanding for at least 270
days, Buyer shall notify Seller and authorize Seller (on Buyer's behalf) to
pursue further collection efforts.

                        REPRESENTATIONS AND WARRANTIES
                            OF THE SELLING PARTIES

     Each of the Shareholders (severally and not jointly) and Seller hereby
represents and warrants to the ABI Parties as follows:

     4.1  ORGANIZATION AND GOOD STANDING.  Seller is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Maryland.  Seller has all requisite corporate power and authority and all
licenses and permits required by any Governmental Body to own and operate its
assets and to carry on its business as now being conducted and as presently
proposed to be conducted except where the failure to do so could reasonably be
expected not to have a DDA Material Adverse Effect.  Complete and correct copies
of the Articles of Incorporation and Bylaws of Seller, and all amendments
thereto, have been previously delivered to the ABI Parties.  Except as disclosed
on Schedule 4.1, Seller is qualified to do business as a foreign corporation in
each jurisdiction in which the nature of the Business or the ownership of the
Purchased Assets requires such qualification, except where the failure to be so
qualified does not and could reasonably be expected not to have a DDA Material
Adverse Effect.  The Shareholders own all of the issued and outstanding capital
stock of Seller in the following percentages: Claude M. Schoch (90%), Robert N.
Snyder (5%), and Philip E. Hixon (5%).

     4.2  SUBSIDIARIES.  The Business and operation of the Purchased Assets,
as carried on by Seller, has not been conducted through any direct or indirect
subsidiary or other Affiliate of Seller.  Seller does not now own nor has Seller
ever owned more than 50% of the outstanding voting capital stock of another
corporation.  Seller does not conduct any operations, business or activities
other than the Business.

     4.3  DUE AUTHORIZATION.  The execution, delivery and performance of
each of this Agreement and the Related Agreements, and the consummation of the
transactions contemplated hereby and thereby, by each Selling Party have been
duly and validly authorized by the Board of Directors of Seller and the
Shareholders by all requisite action on the part of Seller and the Shareholders,
and do not require for their validity any authorization, consent, approval,
exemption or other action by any Governmental Body or other person which has not
been obtained, except where the failure could reasonably be expected not to have
a DDA Material Adverse Effect.  This Agreement and the Related Agreements are
valid and binding agreements of each Selling Party a party thereto, and
enforceable against such Selling Party in accordance with their respective
terms, except as may be required under applicable bankruptcy or other similar
laws affecting the rights of creditors generally.  The Selling Parties'
execution, delivery and performance of this 

                                      22
<PAGE>
 
Agreement and the Related Agreements, and the consummation of the transactions
contemplated hereby and thereby, do not and will not violate, conflict with,
constitute a breach or default or result in the creation of any Liens (other
than Permitted Liens) upon the Purchased Assets under (i) the provisions of the
Articles of Incorporation or By-Laws of Seller, as amended, (ii) any agreement,
contract, indenture or other instrument to which any Selling Party is a party or
by which the Purchased Assets are or may be bound, or (iii) the provisions of
any Order, or any law, rule or regulation having applicability to any Selling
Party or by which the Purchased Assets are or may be bound.

     4.4  FINANCIAL STATEMENTS; NET REVENUES; ASSUMED LIABILITIES.  The
following financial statements of Seller have been delivered to Buyer and Parent
by Seller and Shareholders unaudited balance sheets, income statements,
statements of retained earnings and cash flows of Seller as of and for the years
ended December 31, 1994 and December 31, 1995 (collectively the "Financial
Statements").  The Financial Statements have been prepared from the books and
records of Seller in accordance with GAAP applied on a consistent basis
throughout the periods covered thereby and present fairly in all material
respects the financial condition of Seller as at their respective dates and the
results of operations and cash flows for the periods covered thereby, and the
results of operations of  Seller for such periods  are correct and complete and
are consistent with the books and records of Seller.

     4.5  ABSENCE OF CHANGES OR EVENTS.  Except as disclosed on Schedule
4.5, since the date of the Most Recent Balance Sheet (a) neither Seller nor the
Purchased Assets have suffered any change, event or condition which has had or
may have a DDA Material Adverse Effect, (b) Seller has not made any cash
expenditure other than in the Ordinary Course of Business, and (c) Seller has
not acquired or disposed of any material assets or engaged in any material

the preceding sentence, except as expressly contemplated by this Agreement or as
set forth on Schedule 4.5, since the date of the Most Recent Balance Sheet,
Seller has not:

          (i)    Engaged in any activity which has resulted in the acceleration
or delay of the collection of Receivables or any delay in the payment of
accounts payable, in each case as compared with its custom and practice in the
conduct of its business immediately prior to the date of the Most Recent Balance
Sheet;

          (ii)   Mortgaged or pledged any asset of Seller or subjected any such

     4.6  PERSONAL PROPERTY; PRINCIPAL TANGIBLE ASSETS; INVENTORY.
          ------------------------------------------------------- 

     (a)  Seller has good and marketable title to all tangible and intangible
personal property comprising the Purchased Assets, free and clear of all Liens,
except Permitted Liens.  The documents of transfer to be executed and delivered
by Seller at the Closing will be sufficient to convey good and marketable title
to the Purchased Assets to Buyer, free and clear of all Liens, other than
Permitted Liens or as may be imposed by Buyer.

     (b)  All material machinery, equipment and other tangible assets of Seller
being used in the conduct of the Business or located at the Real Property on the
Closing Date, are usable by or useful to Seller in the ordinary course of its
Business, have been maintained in accordance with normal industry practice, and
are in good operating condition and repair (reasonable wear and tear excepted)
to the extent necessary for the operation of the Business as conducted as of the
date hereof.

     (c)  Attached hereto as Schedule 4.6(c), is a list of the principal
machinery, equipment and other tangible assets owned by Seller and used in the
conduct of  the Business as of the date hereof, or located at the Real Property
on the Closing Date, having a net book value individually in excess of $20,000
(subject to year end adjustments), (collectively, the "Principal Tangible
Assets").

     (d)  Except as described on Schedule 4.6(d), Seller owns or has the right
to use all tangible and intangible personal property necessary for it to conduct
its Business as
          
                                      25
<PAGE>
 
now conducted. All material leases of tangible personal property are described
on Schedule 4.13.

     (e)  Seller's inventory consists of materials and supplies, manufactured
and purchased parts, goods in process, and finished goods, all of which is
merchantable and fit for the purpose for which it was procured or manufactured,
and none of which is slow-moving, obsolete, damaged, or defective, subject only
to the reserve for inventory writedown in accordance with GAAP.

     4.7  REAL PROPERTY.  Seller owns no real property in fee simple.  Attached
hereto as Schedule 4.7 is a list containing a description of all interests in
Real Property used or occupied by Seller.  All real property leases used by
Seller are described in Schedule 4.7, are in full force and effect, and Seller
holds a valid and existing leasehold interest under each of the leases for the
terms set forth on such schedule.  There are no leases, subleases, licenses,
concessions or other agreements written or oral, granting to any third party or
parties the right of use or occupancy of any portion of the Real Property and
Seller is in exclusive possession of the Real Property.  Seller has delivered to
Buyer complete and accurate copies of all materials of Seller concerning such
leases.  Seller has not received or given written notice of any default under
the leases and Seller is not in material default under any of the leases.  No
person has the right to terminate or accelerate performance under or otherwise
modify (including upon the giving of notice or the passage of time) any of such
leases, except in accordance with the provisions thereof.  Seller's leasehold
interests in the Real Property included in the Purchased Assets are free and
clear of all Liens other than Permitted Liens, and are in good operating
condition and repair, normal wear and tear excepted, and are free from any
defects that have, or reasonably could have, a DDA Material Adverse Effect.  To
Seller's Knowledge, there are no existing structural defects in any of Seller's
leasehold interests or encroachments upon the Real Property or interests of
other Persons.  To Seller's Knowledge, the plumbing, mechanical, heating,
ventilation, air conditioning, electrical and water and sewage systems in
Seller's leasehold interests in the Real Property are in good working order and
in compliance with all applicable laws.  The operation of Seller's leasehold
interests in the Real Property by Seller in the manner in which they now are and
have been operated does not violate any zoning ordinances, municipal
regulations, or other rules, regulations, or laws, except for any such
violations which would not, individually or in the aggregate, have a DDA
Material Adverse Effect.  No covenants, easements, rights-of-way, or regulations
of record impair the uses of the respective leaseholds of Seller for the
purposes for which they are now operated by Seller.  There are no pending, or to
the Knowledge of Seller, threatened, condemnation proceedings, lawsuits or

tradename, copyright or registration which has been issued to Seller with
respect to any of its Intellectual Property, identifies each pending application

of all such patents, trademarks, service marks, copyrights, registrations,
applications, licenses, agreements, and permissions (as amended to date) and has
made available to Buyer correct and complete copies of all other written
documentation evidencing ownership and prosecution (if applicable) of each such

                      and possesses all right, title, and interest in and to the
                      item, free and clear of any Lien, license, or any
                      contractual restriction;

               (ii)   the item is not subject to any outstanding Order;

               (iii)  no action, suit, proceeding, hearing, investigation,
                      charge, complaint, claim, or demand is pending or, to the
                      Knowledge of Seller, is threatened which challenges the
                      legality, validity, enforceability, use, or ownership of
                      the item except as disclosed in Schedule 4.9; and

               (iv)   Seller has never agreed to indemnify any Person for or
                      against any interference, infringement, misappropriation,
                      or other conflict with respect to the item.

otherwise come into conflict with, any Intellectual Property rights of third
parties.

enforceable license or lease (as against the licensor or lessor) to use each
material item of Intellectual Property owned by a third party that Seller uses

Schedule 4.10, in the conduct of the Business and operation of the Purchased
Assets, (i) Seller is in compliance with all permits, certificates, licenses,

effect, except where failure could reasonably be expected not to have a DDA
Material Adverse Effect; and Seller has complied with all Laws applicable to
Seller or operation of the Purchased Assets, and Seller has not been issued any
citations, notices or orders of non-compliance under any Law within the three
years preceding the Closing Date. Neither the ownership nor use of the Purchased
Assets nor the conduct of the Business conflicts with the rights of any other
Person, violates or, with or without the giving of notice or the passage of
time, or both, will violate, conflict with or result in a default, right to
accelerate or loss of rights under, any terms or provisions of its Articles of
Incorporation or Bylaws as presently in effect, or any Lien, lease, license,
agreement, understanding, law, ordinance, rule or regulation, or any Order to
which Seller is a party or by which it or the Purchased Assets may be bound or
affected. No consent, qualification, order, approval or authorization of, or
filing with, any governmental authority is required in connection with Seller's
execution, delivery and performance of this Agreement and the consummation of
any transaction contemplated hereby, except where the failure to obtain the same
could reasonably be expected not to have a DDA Material Adverse Effect, or
except as disclosed on Schedule 4.10. The termination of Seller's Employees
employment with Seller will not require that any advance notice of termination
or other notice be given to Seller's Employees or any Governmental Body under
any state or federal law, including the federal WARN Act and comparable
provisions of Maryland law.

<PAGE>
 
          (b)  Except as disclosed on Schedule 4.12, with respect to any
Employee or former employee, Seller has no obligation to contribute to (or any
other liability with respect to) any funded or unfunded Welfare Plan, whether or
not terminated, which provides medical, health, life insurance or other welfare-
type benefits for current or future retirees or former employees (including
their dependents and spouses) except for limited continued medical benefit
coverage for former employees, their spouses and their other dependents as
required to be provided under COBRA, and Seller is in compliance in all material
respects with the continued medical and other welfare benefit coverage
requirements of COBRA and all other applicable laws.

          (c)  Seller has never maintained, contributed to or had any liability
under (or with respect to) any Pension Plan which is a tax qualified "defined
benefit plan" (as defined in Section 3(35) of ERISA) or any tax-qualified
"defined contribution plan" (as defined in Section 3(34) of ERISA), or any non-
qualified deferred compensation plan for certain highly compensated or
management employees whether or not terminated. All contributions (including all
employer contributions and employee salary reduction contributions) which are
due have been paid to each Employee Plan or are reflected as a liability on the
books of Seller and all contributions for any period ending on or before the
Effective Date which are not yet due have been paid to each such Employee Plan
or accrued in accordance with the past custom and practice of Seller. All
premiums or other payments for all periods ending on or before the Effective
Date have been paid with respect to each such Employee Plan which is a Welfare
Plan.

          (d)  Except as disclosed on Schedule 4.12, Seller has, with respect to
all current and former Employee Plans (and all related trusts, insurance
contracts and funds), at all times complied in all material respects with the
applicable requirements of ERISA, the Code, and all other applicable statutes,
common law, regulations and regulatory pronouncements, or has, in the exercise
of its reasonable judgment, determined that such statutes (including ERISA),
common law, regulations and regulatory pronouncements were and are not
applicable to Seller. All required reports and descriptions (including Form 5500
Annual Reports, Summary Annual Reports, PBGC-1's, and Summary Plan Descriptions)
have been filed or distributed appropriately with respect to each such Employee
Plan. The requirements of Part 6 of Subtitle B of Title I of ERISA and of
Section 4980B of the Code have been met with respect to each such Employee Plan
which is a Welfare Plan. Seller has delivered to the Buyer correct and complete
copies of the plan documents and summary plan descriptions, the most recent
determination letter received from the Internal Revenue Service, the most recent
Form 5500 Annual Report, and all related trust agreements, insurance contracts,
and other funding agreements which implement each such Employee Plan. Except as
disclosed on Schedule 4.12, Seller has not engaged in nor is it bound to enter
into, any transaction with respect to any Employee

                                      30
<PAGE>
 
Plan which would subject Seller to any material liability due to either a civil
penalty assessed pursuant to Section 502(i) of ERISA or the tax or penalty on
prohibited transactions imposed by Section 4975 of the Code. No actions, suits
or claims with respect to the assets of any Employee Plan (and all related
trusts, insurance contracts and funds), other than routine claims for benefits,
are pending or threatened which could result in a DDA Material Adverse Effect.
Except as disclosed on Schedule 4.12, there are not now, nor have there been,
any tax-qualified retirement plans sponsored or maintained by Seller for
Employees or former employees since January 1, 1975, nor are there any unfunded
obligations with respect thereto. Seller has no obligation to contribute to (or
any other liability with respect to) any "multi-employer plan," as defined in
the Multi-employer Pension Plan Amendments Act of 1980, and Seller has not
incurred any current or potential withdrawal or termination liability as a
result of a complete or partial withdrawal from any multi-employer plan or the
sale of the Purchased Assets. Except as disclosed on Schedule 4.12, each
Employee Plan intended to qualify under Section 401(a) of the Code has been
determined by the Internal Revenue Service to be qualified under the
requirements of Section 401(a) of the Code, the Internal Revenue Service has
issued a determination letter to that effect, and such letter remains effective
and has not been revoked. No unfulfilled obligation to contribute with respect
to an Employee Plan exists with respect to any Employee Plan year ending on or
before December 31, 1995, except as shown in Seller's Most Recent Balance Sheet.
Except as disclosed on Schedule 4.12, there is no agreement or promise, written
or oral, of Seller to the effect that any Employee Plan may not be terminated at
Seller's discretion at any time, subject to applicable law.

the "Contracts"), other than those relating to (i) Excluded Assets and Excluded
Liabilities; (ii) leases described in Schedule 4.7; (iii) contracts and licenses

enforceable in accordance with its terms and in full force and effect and will
continue to be legal, valid, binding and enforceable, and in full force and
effect on identical terms following consummation of the transactions
contemplated hereby (including the assignments and assumptions provided above).
Except as disclosed in Schedule 4.13, Seller is not and, to the Knowledge of
Seller, no other party thereto is in material default (and no event has occurred
which, with the passage of time or the giving of notice, or both, would
constitute a material default) under any of the Contracts except where default
could reasonably be expected not to have

                                      31
<PAGE>
 
a DDA Material Adverse Effect, and Seller has not waived any right under any of
the Contracts. With respect to the Contracts, no consent, qualification order,
approval or authorization of, or filing with, any Person is required in
connection with Seller's execution, delivery and performance of this Agreement
and the consummation of any transaction contemplated hereby, including the
transfer and assignment of the Contracts to Buyer except as disclosed on

this Agreement before any Court or quasi judicial or administrative agency of

Seller either (i) claimed or raised by any Authority in writing or (ii) as to
which Seller has Knowledge based upon personal contact with any agent of such
authority.  Schedule 4.15 lists all federal, state, local, and foreign income

returns that have been audited or are currently under audit.  Seller has

     4.28 SECURITIES MATTERS.  (a) Neither the Note nor the ABI Shares have been
or will be (except in accordance with the Registration Rights Agreement to be
entered into among  Parent, Seller and such securities the Shareholders)
registered under the Securities Act, or under any state securities laws, and
such securities are being offered and sold in reliance upon federal and state
exemptions for transactions not involving any public offering.  Without limiting
the generality of the preceding sentence, the Note and the ABI Shares have not
been registered under the Maryland Securities Act, Corporations and Associations
Article (the "Maryland Securities Act"), Section 11-501, and therefore, may not
be resold unless such securities are registered under that section or qualify
for an exemption from registration under Section 11-602 of the Maryland
Securities Act.  Two of the Shareholders are residents of the State of Maryland
and the other Shareholder is a resident of Washington, D.C.  Shareholders
understand that the Buyer and Parent are relying upon the representations herein
contained for purposes of applicable "Blue Sky" laws.

     (b)  Seller is acquiring the Note and the ABI Shares for its own account,
with the present intention of holding such securities for purposes of
investment, and not with a view to, or in connection with, the distribution
thereof, subject to Seller's right to transfer any portion or all of the ABI
Shares to the Shareholders pursuant to Section 3.8 above.  Each Shareholder, to
the extent that he acquires the ABI Shares as permitted under Section 3.8 above,
will acquire the ABI Shares for his own account, for investment purposes, and
not with a view to, or in connection with any distribution thereof.

                                      35
<PAGE>
 
     (c)  Seller and each Shareholder is a sophisticated investor with knowledge
and experience in business and financial matters and is an Accredited Investor.
Seller and each Shareholder have received certain information concerning the ABI
Parties and has had the opportunity to obtain such additional information as
Seller or such Shareholder desires in order to evaluate the merits and the risks
inherent in holding the Note and/or the ABI Shares.  Seller and each Shareholder
is able to bear the economic risk and lack of liquidity inherent in holding the
Note and/or the ABI Shares.

     (d)  Neither Seller nor any Shareholder will sell or otherwise distribute
the Note or the ABI Shares in violation of the federal securities laws or any
applicable state securities laws.  Without limiting the generality of the
preceding sentence, neither Seller nor any Shareholder will resell the Note or
the ABI Shares in the absence of a registration or exemption from registration
under the Maryland Securities Act, Corporations and Associations Article,
Section 11-602.

     (e)  Seller and each Shareholder is aware of the provisions of Rule 144/145

material, non-public information.  Seller and Shareholders agree that they will
not make trades in public securities in violation of applicable state or federal
securities laws.

     4.29 PRODUCT LIABILITY.  To Seller's Knowledge, Seller has no liability
(and there is no basis for any present or future action, suit, proceeding,

property as a result of the ownership, possession, or use of any product
manufactured, sold, leased, or delivered by Seller.

     4.30 HART-SCOTT-RODINO.  Schoch represents and warrants (1) that he is the
sole "acquired person" (as defined by 15 U.S.C. (S) 18a(a)) in connection with
the sale of the Purchased Assets to Buyer, and that he is the "ultimate parent
entity" of Seller pursuant to 16 C.F.R. (S) 801.1; and (2) he (including his
spouse and minor children and each entity that he "controls") have annual net
sales of less than $10,000,000 and total assets of less than $10,000,000, each
as defined by 15 U.S.C. (S) 18a(a) and the rules promulgated thereunder, and
therefore he is less than a $10,000,000 "person" under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended.

standing under the laws of their respective states of incorporation and is in
good standing as a foreign corporation in each jurisdiction where failure to so
qualify or be in good standing has or would be reasonably likely to have an ABI
Material Adverse Effect.  Each of Buyer and Parent has the requisite corporate
power and authority to own, lease and operate its properties and assets and to
carry on its businesses as they are now being conducted.  Buyer and Parent have
previously delivered to Seller true and correct copies of their Certificates of
Incorporation and Bylaws, as amended to the date hereof.  Buyer's and Parent's
Certificates of Incorporation and Bylaws as so delivered are in full force and
effect.  Each of the Buyer and Parent is qualified to do business as a foreign
corporation in each jurisdiction where the nature of their business or the
ownership of their assets require such qualification, except where the failure
to be so qualified does not and could reasonably be expected not to have an ABI
Material Adverse Effect.

     5.2 DUE AUTHORIZATION.  The execution, delivery and performance by
Buyer and Parent of each of this Agreement and the Related Agreements, and the
consummation of the transactions contemplated hereby and thereby, have been duly
and validly authorized by all requisite corporate action on the part of Buyer
and Parent, and do not require for their validity any authorization, consent,
approval, exemption or other action by any Governmental Body or other person
which has not been obtained (except (i) to the extent that such Agreements
explicitly contemplate future action, such as the filing of a registration
statement, (ii) Blue Sky, and Form D filings which may be timely made after the
date hereof and (iii) the filing of a NASDAQ National Market notification form
for listing the ABI Shares, which shall be filed promptly after the Closing).
This Agreement 

                                      37
<PAGE>
 
and the Related Agreements are valid and binding agreements of the Buyer and
Parent, enforceable against each of Buyer and Parent in accordance with their
respective terms, except as may be required under applicable bankruptcy or other
similar laws affecting the rights of creditors generally.

     5.3  CAPITALIZATION.  As of the date of this Agreement, the authorized
capital stock of Parent consists of 75,000,000 shares of ABI Common Stock of
which 20,820,160 shares are issued and outstanding.  No other classes of capital
stock are issued and outstanding.  As of the date of this Agreement, options to

Other than as disclosed in or contemplated by this Agreement and the Related

or sell, or cause to be issued, delivered or sold, additional shares of capital
stock of Parent or obligating Parent to grant, extend or enter into any
subscription, option, warrant, right, convertible security or other similar
agreement or commitment.  There are no voting trusts or other agreements or
understandings to which Parent is a party with respect to the voting of the
capital stock of the Company.  All of the outstanding shares of ABI Common Stock
are duly authorized, validly issued, fully paid and nonassessable and free of
preemptive rights.

     5.4  CONFLICTING AGREEMENTS AND CHARTER PROVISIONS.  Except as set
forth in Schedule 5.4, none of (a) the execution and delivery of this Agreement
by the Buyer and Parent, (b) the fulfillment of or compliance with the terms and
provisions hereof by Buyer and Parent or (c) the consummation of any of the
transactions contemplated hereby by Buyer and Parent will conflict with or
result in a breach of the terms, conditions or provisions of, or give rise to a
right of termination under, or constitute a default under, or result in the loss
of any right or benefit under or result in any violation of (in each case with
or without the giving of notice or the passage of time or both), the
Certificates of Incorporation or bylaws of Buyer and Parent or any mortgage,
contract, license, order, arbitration award, judgment, decree, statute, law,
rule or regulation to which any of Buyer or Parent is a party or they or any of
their property is subject, except for such conflicts, breaches, rights of
termination, defaults, losses of rights or benefits, or violations which,
individually or in the aggregate, could not reasonably be expected to have an
ABI Material Adverse Effect.

     5.5  CHANGES SINCE MOST RECENT AUDITED FINANCIAL STATEMENTS.  Since the
date of the most recent audited financial statement of Parent included in the
SEC Reports, there has not been any change, event or occurrence (or to the
Knowledge of Buyer or 

                                       38

     5.8  DEFAULT.  No default exists and no event has occurred which with
notice, lapse of time, or both, would constitute a default in the due
performance and observance of any term, covenant or condition of any indenture
or other agreement or instrument to which Buyer or Parent or any of their
subsidiaries is a party or by which it or any of them is bound, except such
defaults which would not have an ABI Material Adverse Effect.

     5.9  NO COMPARABLE SECURITIES.  Buyer has no outstanding debt
obligations "readily tradable on an established securities market" (within the
meaning of Regulations Section 15A.453-1(e)(4)) that are of a "comparable
character" (within the meaning of Treasury Regulation Section 
15A.453-1(e)(4)(ii)) to the Note.

     5.10  SEC FILINGS.  (a) Parent has filed all reports and statements with
the SEC required to be filed pursuant to the Exchange Act since December 31,
1994, and has made available to Seller copies of all such reports and statements
(the "SEC Reports").  To the Knowledge of Parent, the SEC Reports did not (as of
their respective filing dates) contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading, except to the extent corrected in
subsequently filed SEC Reports.

          (b)  The audited consolidated financial statements, together with the
notes thereto, of Parent included (or incorporated by reference) in the SEC
Reports fairly present the financial position of Parent and its consolidated
subsidiaries as of the dates thereof and the results of their operations and
changes in financial position for the periods then ended in accordance with GAAP
(except as stated in such financial statements).

any Shareholder intentionally misrepresents a fact or fraudulently conceals a
material fact, in which event, Buyer and Parent shall be conclusively presumed
to have relied on such intentional misrepresentation or to have been misled by
such fraudulent concealment, as the case may be.

conditions herein provided, each of the parties hereto agrees to use its
reasonable best efforts to take, or cause to be taken, all action, and to do, or
cause to be done, all things reasonably necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement.  As used herein, "Further
Assurances" shall mean any deeds, assignments, powers of attorney or other
documents which may be reasonably required to transfer ownership of the
Purchased Assets to Buyer, to confirm such ownership or facilitate effective
recordation thereof, or to put Buyer in actual possession and operating control
of the Purchased 

                                       40
<PAGE>
 
Assets. As soon as practicable after any request for Further Assurances made by
Buyer at or after the Closing Date, Seller or the Shareholders, or both, shall
either execute such Further Assurances and deliver them to Buyer or cause them
to be executed and delivered to Buyer (i) without any charge to Buyer and (ii)
in proper form for any required recording, filing or registration.

     6.2  ACCESS TO RECORDS AFTER CLOSING.  After the Closing Date, Buyer on the
one hand and Seller on the other hand agree that they will give, or cause to be
given, to the other party, its successors and its representatives, during normal
business hours and at the requesting party's expense, such reasonable access to
the properties, titles, contracts, books, records, files, personnel, officers,
agents, employees, independent auditors, independent auditor's files and
documents (but excluding attorney work product or other privileged
communications) of Buyer or Seller to the extent such records relate to the
Business, including records necessary for calculating the Annual Net Revenue and
the Closing Deficit Amount, as is reasonably necessary to allow the requesting
party to obtain information in the other party's possession with respect to any
claims, demands, audits, suits or matters of a similar nature made by or against
the requesting party as the previous or new owner and operator of the Business,
as the case may be, and to make copies of such information to the extent
reasonably necessary.

     6.3  BULK SALES COMPLIANCE.  Buyer hereby waives compliance by Seller with
the provisions of the Bulk Sales Law of any state, and the Selling Parties
severally and not jointly warrant and agree to pay and discharge when due all
bona fide claims of creditors of Seller actually made against the ABI Parties or
which have been or will be asserted against Buyer and Parent or either of them
by reason of such non-compliance to the extent that such liabilities are not
included within the Assumed Liabilities under this Agreement.  Each Shareholder
(severally and not jointly) and Seller hereby indemnifies and agrees to hold
harmless from, against and in respect of (and shall on demand reimburse for) any
loss, liability, cost or reasonable expense, including reasonable attorneys'
fees, suffered or incurred by Buyer and Parent or either of them by reason of
the failure of Seller to pay or discharge such claims (other than Assumed
Liabilities).

     6.4  CERTAIN EMPLOYEE MATTERS.

          (a)  Responsibilities of Seller.  Seller shall use its reasonable best
efforts to encourage all Employees of the Business to accept Buyer's offer of
employment. Seller shall also release such Employees who accept employment with
Buyer from any covenant not to compete to which it is a party.

to offer employment to all Employees of Seller prior to Closing (excluding laid
off or

                                       41
<PAGE>
 
previously-terminated or retired employees) on terms and conditions
determined by Buyer.  From and after the Closing Date, Buyer will provide
benefits (or cash compensation in lieu thereof) to the Employees which will, in
the aggregate, be no less favorable than those provided by Buyer to its
similarly situated employees from time to time.  With respect to the Employee
Plans and Welfare Plans of Buyer, Buyer shall grant the Employees from and after
the Closing Date credit for all service with Seller prior to the Closing Date
for all purposes for which such service was recognized by Seller.  To the extent
Buyer's benefit plans (or any new benefit plans entered into for the Employees)
provide medical or dental welfare benefits after the Closing Date, Buyer shall
use its reasonable best efforts to cause such plans to waive any pre-existing
conditions and actively-at-work exclusions and shall use reasonable best efforts
to provide that any expenses incurred on or before the Closing Date shall be
taken into account under any Buyer benefit plans for purposes of satisfying
applicable deductible, coinsurance and maximum out-of-pocket provisions.
Nothing in this section shall create any third party beneficiary rights.

     6.5  ALLOCATION OF PURCHASE PRICE.  Only for purposes of reporting the
transaction reflected by this Agreement on any federal state or other income tax
returns, the parties agree that the allocation of the Purchase Price shall be as
set forth in the Allocation Memorandum, attached hereto as EXHIBIT F and by this
reference incorporated herein. Neither party shall make any claims or treat any
items on its respective federal, state or other tax returns in a manner which is
inconsistent with the Allocation Memorandum.

change its corporate name to a name which does not include, and which is not
confusingly similar to, "Digital Directory Assistance", the initials "DDA," or
any name listed on Schedule 4.11 (Intellectual Property), it being the intent of
Seller and the Shareholders that from and after the Closing the Buyer shall have
the sole and exclusive right to conduct business under such name or names and
that Buyer will commence doing so at the time of the Closing.

     6.7  SALES, USE, TRANSFER AND OTHER TAXES.  Any sales and use taxes and
real property transfer taxes imposed on the purchase, sale, use or transfer of
any of the Purchased Assets by Seller to Buyer on or prior to the Closing Date
shall be paid by Seller.

same set of facts gives rise to a breach of a

                                      46
<PAGE>
 
Surviving Seller Representation, a purchase price adjustment under Article III

Indemnified Parties shall have the right to make claim under any other
provisions of this Agreement or proceed ex contractu at law or in equity based
on any available theory including tort and violation of statute.

          (b) Notwithstanding the provisions of Section 9.2(a), Buyer and Parent
shall have no obligation to indemnify the Seller Indemnified Parties from and
against Losses resulting from, arising out of, relating to, in the nature of, or
caused by, the breach (or alleged breach) of any representation or warranty of
Buyer or Parent or any one or more of them (other than the Surviving Buyer

Indemnified Parties for any breach of any representation or warranty of Buyer or

facts gives rise to a breach of a Surviving Buyer Representation, a right of
indemnity under Section 9.2(c) or (d) or involve intentional acts of fraud (as
opposed to negligent misrepresentation) by Buyer or Parent, or any one or more
of them, in which event or events, the provisions of this Section 9.3(b) and

right to make claim under any other provisions of this Agreement or proceed ex
contractu at law or in equity based on any available theory including tort and

Selling Parties, on the other hand, be liable for an amount in the aggregate
greater than 100% of the Final Purchase Price for all claims made against them
under Sections 9.1(b) or 9.2(a), as the case may be.

     9.4  CALCULATION OF LOSSES. For purposes of this Article IX, (a) the amount
of any Loss shall be calculated net of insurance proceeds received by the
indemnified party in connection with such Loss, (b) the amount of any Loss shall
be calculated taking into account any tax benefit or detriment actually
realized, on a "with-or-without" basis, by the indemnifying party or the
indemnified party as a result of or in connection with either

                                      47
<PAGE>
 
the matter, event or condition giving rise to such Loss and (c) the amount of
any Loss, shall be reduced to the extent such Loss reduced the Final Purchase
Price under the adjustments provided in Section 3.3.

     9.5  COOPERATION. (a) Notice. The Selling Parties and the ABI Parties will
each give prompt written notice to the other of any assertion, claim or demand
which the ABI Parties or the Selling Parties discover or of which notice is
received after the Closing and which might give rise to a claim by the ABI
Parties against the Selling Parties under Section 9.1 hereof, or by the Selling
Parties against the ABI Parties under Section 9.2 hereof, stating in reasonable
detail the nature, basis and amount thereof; provided, however, the failure to
give such notice shall not affect any claim for indemnification thereunder
unless such failure to give notice materially and adversely affects the
indemnifying party's ability to defend against such assertion, claim or demand.

          (b)  Claims. In case of any claim by a third party with respect to
which the indemnifying party may have liability under the indemnity agreements
contained in Section 9.1 or Section 9.2 hereof, the indemnifying party shall be
entitled to participate therein, and, to the extent desired, to assume the
defense thereof, and after notice from the indemnifying party of its election so
to assume the defense thereof, the indemnifying party will not be liable to the
indemnified party for any legal or other expenses subsequently incurred (but
shall remain liable for such costs and expenses previously incurred after notice
of the claim to the indemnifying party) by the indemnified party in connection
with the defense thereof, other than reasonable costs of investigation, unless
the indemnifying party does not actually assume the defense thereof following
notice of such election or unless the indemnified party has defenses available
to it that are different than, or in conflict with, those available to the
indemnifying party. The ABI Parties and the Selling Parties each shall make
available to the other and their attorneys and accountants, at all reasonable
times, all books and records relating to such suit, claim or proceeding, and the
ABI Parties and the Selling Parties will render to each other such assistance as
may reasonably be required of each other in order to insure proper and adequate
defense of any such suit, claim or proceeding. The ABI Parties and Seller will
not make any settlement of any claim which might give rise to liability of the
indemnifying party under Section 9.1 or Section 9.2 hereof without the consent
of the other, which consent shall not be unreasonably withheld. If the
indemnifying party shall desire and be able to effect a monetary compromise or
settlement of any such claim solely for money damages which settlement or
monetary compromise shall fully and finally relieve the indemnified party of any
liability in connection with such cause of action and claim and the indemnified
party shall refuse to consent to or participate in such compromise or settlement
(to the extent it relates to money damages), then the liability of the
indemnifying party to the indemnified party with respect to settlement of such
claim shall be limited to the amount so offered in compromise or settlement and
the

                                      48
<PAGE>
 
Indemnifying Party shall have no continuing liability for attorney fees or
litigation expenses of the Indemnified Party or obligation to defend the
Indemnified Party thereafter if it pays over the amount of such indemnification
to the Indemnified Party.

          (c)  Control of Defense: Exceptions. Notwithstanding the provisions of
Section 9.3(b): (i) the indemnified party will be entitled to participate in the
defense of any claim and to employ counsel of its choice for such purpose at its
own expense (provided that the indemnifying party will bear the reasonable fees
and expenses of such separate counsel for the indemnified party incurred after
notice of the claim to the indemnifying party and prior to the date upon which
the indemnifying party effectively assumes control of such defense), and (ii) at
the option of the indemnified party, the indemnifying party will not be entitled
to assume control of the defense of any such claim, and will pay (in addition to
any other Losses for which the indemnifying party may be responsible) 50% of the
reasonable fees and expenses of legal counsel retained by the indemnified party
(not to exceed the amount of any monetary claims by the third party in any case
involving claims for monetary damages), if:

               (A)  the indemnified party reasonably believes that an adverse
                    determination of such proceeding could be materially
                    detrimental to or could materially injure the indemnified
                    party's reputation or future business prospects; or

               (B)  the indemnified party reasonably believes that there exists
                    or could arise a conflict of interest which, under
                    applicable principles of legal ethics, could prohibit a
                    single legal counsel from representing both the indemnified
                    party and the indemnifying party in such proceeding.

     9.6  SURRENDER OF ABI SHARES. Any Selling Party may, at its or his
election, satisfy any obligation to indemnify any ABI Indemnified Party for a
Loss under Section 9.1(b) by surrendering that number of ABI Shares having an
aggregate fair market value equal to such Loss. For purposes of this Section
9.6, the "fair market value" of ABI Shares shall be the average of the closing
price of ABI Common Stock for the five trading days immediately preceding the
date such shares are surrendered.

                  SURVIVAL OF REPRESENTATIONS AND WARRANTIES

     10.1  SEVERAL LIABILITY. Each statement, representation, warranty,
indemnity, covenant and agreement made by the Selling Parties in this Agreement
and in any document, Schedule, certificate or other instrument delivered by or
on behalf of the Selling Parties pursuant to this Agreement or in connection
herewith shall be deemed to be the several (and not joint) statement,
representation, warranty, indemnity, covenant and agreement of the Selling
Parties.

     10.2  SURVIVAL. Except as otherwise set forth in this Section 10.2, the
representations and warranties made in this Agreement shall survive the Closing
until the second anniversary of the Closing Date and shall thereupon expire
together with any right to indemnification for breach thereof (except to the
extent a written notice asserting a claim for breach of any such representation
or warranty shall have been given prior to such date to the party which made
such representation or warranty, in which case such representation and warranty
shall survive, to the extent of such claim only, until such claim is resolved).
Notwithstanding any other provision hereof, the representations and warranties
of the Selling Parties contained in Section 4.1 (Organization and Good
Standing), Section 4.2 (Subsidiaries), Section 4.3 (Due Authorization), Section
4.6 (a) (Personal Property), Section 4.9 (a) (Intellectual Property), Section
4.15 (Taxes), Section 4.21 (Brokers), Section 4.28 (Securities Matters), and
Section 4.30 (Hart-Scott-Rodino) (collectively, the "Surviving Seller
Representations") and the representations and warranties of Buyer and Parent
contained in Section 5.1 (Organization and Good Standing), Section 5.2 (Due
Authorization), Section 5.6 (No Brokers), Section 5.13 (ABI Shares), and Section
5.14 (Reliance) (collectively, the "Surviving Buyer Representations") shall
survive the Closing until the expiration of the applicable statute of
limitations. The covenants and agreements contained in this Agreement to be
performed or complied with prior to the Closing shall expire at the Closing. The
covenants and agreements contained in this Agreement to be performed or complied
with at or after the Closing (other than the covenant and agreement to indemnify
against certain breaches of representations and warranties, which shall expire
as set forth in the first sentence of this Section 10.2) shall survive the
Closing until the expiration of the applicable statute of limitations.

     11.1  MODIFICATIONS; WAIVER. Any amendment, change or modification of this

party shall

                                      50
<PAGE>
 
waive any right under this Agreement unless such waiver is in writing and signed
by the party waiving such right. No failure or delay by any Party hereto in
exercising any right, power or privilege hereunder (and no course of dealing
between or among any of the parties) shall operate as a waiver of any such
right, power or privilege. No waiver of any default on any one occasion shall
constitute a waiver of any subsequent or other default. No single or partial
exercise of any such right, power or privilege shall preclude the further or
full exercise thereof.

     11.2  NOTICES. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given when personally delivered,
mailed by certified mail, return receipt requested, or via Federal Express or

Agreement may be made by facsimile transmission by any party of an executed
signature page to be affixed to the Agreement, with originals of such signature
page(s) to follow by courier.

     11.4  EXPENSES.  Each of the parties hereto will bear all costs, charges
and expenses incurred by such party in connection with this Agreement and the
consummation of the transactions contemplated herein.

     11.5  BINDING EFFECT; ASSIGNMENT.  This Agreement shall be binding upon
and inure to the benefit of the ABI Parties and the Selling Parties, their
heirs, representatives, successors, and permitted assigns, in accordance with
the terms hereof.  This Agreement may not be assigned by Seller or Shareholders
without the prior written consent of the ABI Parties, or by the ABI Parties
without the prior written consent of Seller, and any such assignment shall be
void and of no force or effect; provided, however, that no such consent shall be
required of the ABI Parties to assign part or all of their rights and
obligations under this Agreement to one or more of their Affiliates, but no such
assignment by the ABI Parties of their rights and obligations hereunder shall
relieve the 

                                      53
<PAGE>
 
ABI Parties of any of their obligations under this Agreement or be
made if any Selling Party would incur any  additional taxes, costs or expenses
as a result of such assignment.

     11.6  ENTIRE AND SOLE AGREEMENT.  This Agreement and the other schedules
and agreements referred to herein, constitute the entire agreement between the
parties hereto and supersede all prior agreements (including, but not limited
to, any letter of intent executed by the parties), representations, warranties,
statements, promises, information, arrangements and understandings, whether oral
or written, express or implied, with respect to the subject matter hereof.

     11.7  GOVERNING LAW.  This Agreement and its validity, construction,
enforcement, and interpretation shall be governed by the substantive laws of the
State of Maryland, without giving effect to conflicts of law.

     11.8  SEVERABILITY.  Any term or provision of this Agreement, which is
invalid or unenforceable in any jurisdiction, shall be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this Agreement or affecting
the validity or enforceability of any of the terms or other provisions of this
Agreement in any other jurisdiction.

     11.9  PUBLIC ANNOUNCEMENTS.  The Selling Parties shall obtain the ABI
Parties' written consent before making, and the ABI Parties shall obtain
Seller's written consent before making, any public announcements with respect to
this Agreement, any related agreement or the transactions contemplated hereunder
or thereunder, unless such public announcement is required under applicable
laws.

     11.10  CONFIDENTIALITY.  Seller, Shareholders and their collective
representatives shall forever treat confidentially all information concerning
the terms and conditions of this Agreement, all related agreements, and of the
transactions contemplated hereunder or thereunder (collectively, "Confidential
Information"); provided, however, that Confidential Information shall not
include information which is or becomes generally known to the public not as a
result of any breach of this provision by Seller, Shareholders or their
representatives.  Seller's, Shareholders' and their representatives' obligation
to treat the Confidential Information confidentially shall not apply to the
extent that Seller, Shareholders or their representatives shall be required to
disclose any such information in connection with an investigation or legal
proceeding where the failure to disclose such information could result in
liability for contempt or other censure or penalty; provided, however, that
Seller, Shareholders and their representatives shall notify the ABI Parties as
soon as possible and in any event prior to such disclosure and shall cooperate
with the ABI Parties in the event that the ABI Parties elect to legally contest
such disclosure.

     11.11  REMEDIES CUMULATIVE.  The remedies of the parties under Article
IX of this Agreement are cumulative and, except as otherwise provided in Section
9.3, shall not exclude any other remedies to which any party may be lawfully
entitled.

     11.12  FURTHER ASSURANCES.  From time to time after the Closing, at the
request of the ABI Parties or Seller but without further consideration, Seller
or the ABI Parties will each execute and deliver such other instruments of
conveyance, assignment, assumption, transfer, and delivery and take such other
action as the ABI Parties or Seller reasonably may request in order to
consummate the transactions contemplated hereby.

     11.13  HEADINGS.  The descriptive section headings are for convenience
of reference only and shall not control or affect the meaning or construction of
any provision of this Agreement.

     11.14  CONSTRUCTION.  The language in all parts of this Agreement shall
in all cases be construed as a whole according to its fair meaning, strictly
neither for nor against any party hereto, and without implying a presumption
that the terms thereof shall be more strictly construed against one party by
reason of the rule of construction that a document is to be construed more
strictly against the person who himself drafted same.  It is hereby agreed that
representatives of both parties have participated in the preparation hereof.
