                                     OPTIONS



         SECTION 1.1 GRANT OF OPTION TO PURCHASE PARTNERSHIP  INTEREST.  Subject

to the terms and conditions of this  Agreement,  Partners hereby grant to ACI an

 -----



         SECTION 1.2 CONSIDERATION FOR OPTION. In consideration for the grant of

the  Option,  ACI  shall pay to the  Partners  the sum of  $10.00  (the  "Option

                                                                          ------

Price,").

- -----



         SECTION 1.3.  EXERCISE  PRICE.  If ACI  exercises the Option during the

Option Term (as hereinafter defined),  the exercise price (the "Exercise Price")

                                                                --------------

shall be the Partnership Interest Value. As used herein,  "Partnership  Interest

                                                           ---------------------

Value" shall mean the value of the Partners Partnership Interest,  determined by

- -----

a nationally  recognized  investment banking firm (the "Initial Banker"),  to be

                                                        --------------

mutually  agreed upon by the  Partners  and ACI (or if the  Partners and ACI are

unable to agree,  the New York office of Merrill  Lynch & Co.), in light of such

investment  banking firm's  evaluation of Billing's  current  earnings as of the

date the Option Exercise Notice (as hereinafter  defined) and such other similar

matters that such investment banking firm shall deem relevant less the aggregate

amount of  distributions  received by the either  Partner  that was not made pro

rata to all the  limited  and general  partners  of the  Partnership;  provided,

                                                                       --------

however,  such  investment  banker shall not consider the  following  factors in

- -------

determining the Partnership Interest Value:



         (i) minority interest discounts or controlling interest premiums;

         (ii) fees or overhead paid to or allocated from ACI; or

         (iii) amortization of intangibles resulting from acquisitions.



         Upon  ACI's  receipt  of  the  Initial  Banker's  determination  of the

Partnership  Interest  Value,  it shall  promptly  notify the  Partners  of such

determination  and the assumptions and methodology  utilized in arriving at such

determination  and provide the written  opinion of the Initial  Banker as to its

determination. If within 30 Business Days of receipt of such determination,  the

Partners  shall not object  thereto,  ACI will  consummate  the  exercise of the

Option.  If within such 30-day  period the  Partners  shall object in writing to

such  determination,  the Partners may appoint,  at its sole cost and expense, a

nationally  recognized  investment  banking  firm (the  "Partners'  Banker")  to

                                                         -----------------

undertake  separately the evaluation  prescribed  above.  Not later than 60 days

following  its written  notice to ACI of its  objection to the Initial  Banker's

determination,  the  Partners  shall  provide  ACI with the  Partners'  Banker's

determination, including the assumptions and methodology utilized in arriving at

such determination and provide the written opinion of the Partners' Banker as to

its determination. If the Partners do not provide ACI with these materials



                                       -2-


                                                            FINAL SIGNATURE COPY



within the 60-day period  prescribed  above, ACI shall be entitled to consummate

the exercise of its option pursuant hereto. The fees and expenses of the Initial

Banker  shall be borne by ACI.  The time  limits  herein may be  extended by the

parties to provide  the  investment  bankers  such  additional  time as they may

request.



         If within 30 days of the delivery of the determination of the Partners'

Banker,  the Partners' Banker and the Initial Banker are unable to resolve their

differing  determinations  and  arrive at an  agreed  upon  value,  then a third

nationally  recognized investment banking firm, selected by the agreement of the

Initial  Banker  and  the  Partners'   Banker,   shall  undertake  to  make  the

determinations  prescribed above. Such investment  banker's  determination as to

the Partnership  Interest Value shall be delivered to ACI and the Partners along

with the assumptions and methodology  utilized in arriving at such determination

as  well  as  the  written  opinion  of  such   investment   banker  as  to  its

determination.  At such time, the Partnership  Interest Value shall be deemed to

be the simple average of the two closest  determinations by the three investment

bankers,  which  determination  shall  be  final  and  binding  upon ACI and the

Partners.  The fees and expenses of such third investment  banker shall be borne

equally by ACI, on the one hand, and the Partners,  on the other hand, and shall

be paid in advance of the performance of such service.



         SECTION 1.4 PAYMENTS.  The Exercise Price may be paid in (i) cash, (ii)

shares of ACI common  stock,  par value $.01 per share ("ACI  Common  Stock") or

(iii) any combination of cash and shares of ACI Common Stock as ACI, in its sole

discretion, determines; provided however, ACI shall pay sufficient consideration

                        ----------------

in cash to permit the  Partners to pay  applicable  federal  income tax (if any)

that is payable as a result of the exercise of the Option. If the Exercise Price

is paid, in whole or in part, with shares of ACI Common Stock,  the value of ACI

Common  Stock  shall be its  Current  Market  Value.  As used  herein,  the term

"Current  Market  Value"  means,  if on such date ACI Common  Stock is listed or

 ----------------------

admitted to trading on any national  securities exchange or quoted on the Nasdaq

Stock Market  ("NASDAQ") or otherwise traded in the  over-the-counter  market in

                ------

the United States,  the mean average  closing price for the 50 consecutive  days

before the fifth business day preceding the Closing Date; or if on such date ACI

Common  Stock is not listed or  admitted to trading on any  national  securities

exchange  or quoted on the NASDAQ or  otherwise  traded in the  over-the-counter

market in the United States, the amount that a willing buyer would pay a willing

seller in an arm's  length  transaction  on such date  (neither  being under any

compulsion  to buy or sell) for such security as determined on the same basis as

the Exercise  Prices is determined  under  Section 1.3. The Partners  shall have

registration  rights with respect to the ACI Common Stock by becoming parties to

that  Registration  Rights  Agreement  attached  as Exhibit B to the HOLD Merger

Agreement;  provided however, the piggy back registration rights of the Partners

            ----------------

shall be effective at the date of the Exercise Option Notice and shall expire on

the  earlier of (i) three  years from the Option  Closing  Date (as  hereinafter

defined)  and (ii) the date on which any Holder (as defined in the  Registration

Rights  Agreement)  may sell  shares of  Registrable  Stock (as  defined  in the

Registration  Rights  Agreement) under section k of Rule 144,  promulgated under

the Securities Act of 1933, (or any successor provision).

         SECTION 1.5  EXERCISE OF  OPTION;TERM.  The Option  shall  become fully

exercisable  on the second  anniversary of the closing of the merger of ACI with

and into  HOLD and  shall  remain  fully  exercisable  for a period of two years

thereafter (the "Option Term"). ACI may exercise the Option in whole, but not in

                 -----------

part,  at any time before the  expiration  of the Option Term by giving  written

notice of exercise (the "Option Exercise Notice") to the Partners.

                         ----------------------



         SECTION 1.6 OFFER TO PURCHASE OF MERGER SUB'S PARTNERSHIP  INTEREST. If

ACI does not exercise the Option during the Option Term,  the Partners may offer

(the "Offer") to purchase  Merger Sub's  Partnership  Interest and its rights in

      -----

its  Partnership  Interest by giving  written  notice of the Offer to Merger Sub

within 120 days after the  expiration  of the Option  Term.  Such  notice  shall

contain  the  purchase  price  (the  "Offer  Price")  and the  other  terms  and

                                      ------------

conditions of the Offer,  together with such  information or documentation as is

reasonably  satisfactory  to ACI to  demonstrate  the financial  capacity of the

Partners to consummate the purchase of the Partnership Interest. Merger Sub may,

in its sole discretion, accept or reject the Offer.



         SECTION 1.7 SECOND OPTION.  If Merger Sub rejects the Offer,  ACI shall

purchase all of the Partners'  Partnership  Interest and Partners  Rights in the

Partnership Interest on the same terms and conditions as contained in the Offer,

except the Offer  Price for the  Partners'  Partnership  Interest  and  Partners

Rights in the Partnership  Interest of the Partners shall be reduced pro rata to

reflect the aggregate Partnership Interest then owned by the Partners. The Offer

Price  shall be  payable  upon the same  terms  and  conditions  as set forth in

Section 1.4.

regulations.



         SECTION 4.3 NOTICE OF BREACH.  In the event of, and promptly after, the

taking of any action or the impending or threatened occurrence of any event, the

cause the general  partner of the  Partnership  to  distribute an amount of cash

sufficient  to enable  each  partner to pay its  portion  of federal  income tax

arising from its allocable share of Partnership activities, assuming the highest

marginal  tax rate under  Section 1 of the  Internal  Revenue  Code of 1986,  as

amended from time to time.



         SECTION 4.6 WITHDRAWAL OF CAPITAL.  In connection with the consummation

prepared and is to contain a separate  statement  detailing the capital accounts

of the Partners as at the closing of HOLD Merger  Agreement (the "Merger Closing

                                                                  --------------

Partnership  in  four  equal  installments  beginning  on the  first  day of the

calendar  quarter  beginning  after the date of the  balance  sheet  referred to

herein is  provided  to ACI,  and on the first  day of the next  three  calendar

quarters   thereafter.   The  Partnership  shall  not  be  required  to  make  a

distribution to the Partners if (i) such distribution would reduce either of the

capital  accounts of the  Partners to less than zero,  or (ii) if to do so would

materially  adversely affect the cash flow  requirements of the Partnership.  If

either condition shall exist on any distribution  date, that  distribution  date

and all  future  distribution  dates  shall be  automatically  extended  for one

calendar quarter.



         SECTION 4.7 LINE OF CREDIT.  ACI shall use its reasonable  best efforts

or waiver is sought. Any such waiver shall constitute a waiver only with respect

the parties, on one or more occasions,  to enforce any of the provisions of this

Agreement or to exercise any right or privilege hereunder, shall be construed as

a waiver of any other breach or default of a similar  nature,  or as a waiver of

be affected or deemed waived by reason of any investigation made by or on behalf

of Merger Sub or ACI (including by any of their respective advisors, consultants

or  representatives)  or by reason of the fact that  Merger Sub or ACI or any of

such advisors, consultants or representatives knew or should have known that any

such  representation or warranty is or might be inaccurate.  The representations

and  warranties  of Merger Sub and ACI shall not be affected or deemed waived by

reason of any investigation  made by or on behalf of Partners  (including by any

of their respective  advisors,  consultants or  representatives) or by reason of

the fact that Partners or any of such advisors,  consultants or  representatives

knew or should have known that any such  representation  or warranty is or might

be inaccurate.
