<PAGE>

          1.1 The Merger. On the terms and subject to the conditions of this
Agreement, at the Effective Time (as defined below), PRG II shall be merged

          1.2 Articles of Incorporation and By-laws of Surviving Corporation.
At the Effective Time, the Articles of Incorporation and By-laws of Haas then

franchises, privileges, rights and immunities of Haas shall continue unaffected
and unimpaired by the Merger and the corporate franchises, existence and rights
of PRG II shall be merged with and into Haas, and Haas, as the Surviving
Corporation, shall be fully vested therewith. At the Effective Time, the
separate existence of PRG II shall cease and, in accordance with the terms of
this Agreement, the Surviving Corporation shall possess all the rights,
privileges, immunities and franchises, of a public, as well as of a private,
nature, and all property, real, personal and mixed, and all debts due on
whatever account, including subscriptions to shares, and all taxes, including
those due and owing and those accrued, and all other choses in action, and all
and every other interest of or belonging to or due to Haas or PRG II shall be
taken and deemed to be transferred to, and vested in, the Surviving Corporation
without further act or deed; and all property, rights and privileges, powers and
franchises and all and every other interest shall be thereafter as effectually

the title to any real estate, or interest therein, whether by deed or otherwise,
vested in Haas or PRG II, shall not revert or be in any way impaired by reason

<PAGE>

Neither the rights of creditors nor any liens upon the property of Haas or PRG
II shall be impaired by the Merger, and all debts, liabilities and duties of
Haas and PRG II shall attach to the Surviving Corporation, and may be enforced
against the Surviving Corporation to the same extent as if such debts,
liabilities and duties had been incurred or contracted by the Surviving
Corporation.

          1.4 Manner of Conversion. The manner of converting the shares of (i)
outstanding capital stock of Haas ("Haas Stock"), and (ii) outstanding capital
stock of PRG II ("PRG II Stock") shall be as follows:

          As of the Effective Time:
          (a) Each share of Haas Stock issued and outstanding immediately prior
to the Effective Time, and each of the Option Shares (on an "as-exercised basis"
pursuant to which the Van Hercke Option shall be deemed exercised by Thomas J.
Van Hercke), by virtue of the Merger and without any action on the part of the
holder thereof, automatically shall be converted into the right to receive its
pro rata interest in the aggregate sum of Seven Million Dollars ($7,000,000),
including its pro rata interest in the Escrow Amount, subject to the provisions
of Section 1.5 hereof, payable as follows:

               (i) by payment of the sum of $6,472,500 at the Closing (the
          "Closing Cash Payment"). The Closing Cash Payment shall be divided and
          paid by to the Stockholders by wire transfer of immediately available
          funds to the bank accounts designated, respectively, by the
          Stockholders, in writing, at least three (3) days prior to the Closing
          Date. The portion of the Closing Cash Payment paid to each Stockholder
          shall be a percentage equal to the percentage of the Haas Shares held
          by such Stockholder on the Closing Date; and

               (ii) by placing the sum of $527,500 (the "Escrow Amount"), in
          escrow with the Escrow Agent at the Closing pursuant to the terms and
          conditions of Section 1.5 below. 

          (b) All shares of Haas Stock, if any, that are held by Haas as
treasury stock shall be canceled and retired, and no consideration shall be
delivered or paid in exchange therefor; and

                                       3
<PAGE>

          (c) Each share of PRG II Stock issued and outstanding immediately
prior to the Effective Time, shall, by virtue of the Merger and without any
action on the part of PRG, automatically be converted into one fully paid and
non-assessable share of common stock of the Surviving Corporation, which shall
constitute all of the issued and outstanding shares of common stock of the
Surviving Corporation, and shall be owned by PRG, immediately after the
Effective Time.

          1.5    Release of Escrow Amount; Purchase Price Adjustment.

               (a) The Escrow Amount shall be held in escrow by the Escrow
          Agent, in an interest bearing account reasonably satisfactory to
          Stockholders, and distributed in accordance with the provisions of
          this Section 1.5.

               (b) On or before February 28, 1999, Stockholders shall at PRG's
          cost and expense, (i) cause management of Haas or Davich, Wilson,
          Morrow & Associates, P.A. (each, an "Auditor") to deliver to PRG and
          Stockholders a balance sheet of Haas as at December 31, 1998 and
          income statement for the year then ended (the "Financial Statement"),
          prepared in accordance with GAAP applied consistently with prior
          financial statements of Haas (which shall be audited if requested by
          PRG or Stockholders), and (ii) deliver to Stockholders, PRG and the
          Escrow Agent a certificate setting forth the Auditor's calculation of
          Haas's earnings before interest and taxes ("EBIT") for the year then
          ended (the "Auditor's Certificate"). The calculation of EBIT shall
          take into account all management bonuses paid or payable with respect
          to the year ended December 31, 1998 (the "Management Bonuses). Haas
          shall make, or cause to be made, available to Stockholders all Haas
          internal and Auditor work papers and other supporting documentation
          provided or reasonably available to Haas and related to the
          preparation of the Financial Statement. Notwithstanding anything
          contained herein, in the event that PRG makes any changes in
          operations, personnel, location, management or financial accounting of
          Haas during the period from the Closing Date through December 31,
          1998, EBIT shall be adjusted by the Auditor as if such changes had not
          been made. In addition, EBIT shall be increased by the amount of any
          compensation or similar charge resulting  


                                       4
<PAGE>

from the exercise of the Van Hercke Option.

               (c) Unless PRG gives Stockholders and the Escrow Agent written
          notice of its objection to the Auditor's calculation of EBIT ("Notice
          of Objection"), which notice shall include the basis of PRG's
          objection in reasonable detail and shall set forth PRG's calculation
          of EBIT based on such objection (the "PRG EBIT Proposal"), within
          twenty (20) business days after receiving the Financial Statement and
          the Auditor's Certificate (the "Objection Period"), the Financial
          Statement and the Auditor's calculation of EBIT set forth in the
          Auditor's Certificate shall be final, conclusive and binding on the
          parties to this Agreement.

               (d) If PRG delivers a Notice of Objection within the Objection
          Period, PRG and Stockholders shall use reasonable efforts to resolve
          all disputes. If PRG and Stockholders are not able to resolve all
          disputes set forth in the Notice of Objection within 10 days after
          PRG's delivery of the Notice of Objection, the remaining disputed
          items shall be submitted for final resolution to a mutually agreeable
          accounting firm of national reputation (the "Independent
          Accountants"). Prior to final selection of the Independent
          Accountants, each of the parties shall disclose any relationship such
          party has, or within the previous three (3) years had, with such
          Independent Accountants. In submitting the dispute to the Independent
          Accountants, each of the parties shall concurrently furnish, at its
          own expense, to the Independent Accountants and the other parties such
          documents and information as the Independent Accountants may request.
          Each party may also furnish to the Independent Accountants such other
          information and documents as it deems relevant, with the appropriate
          copies and notification being concurrently given to the other party.
          Neither party shall have or conduct any communication, either written
          or oral, with the Independent Accountants without the other party
          either being present or receiving a concurrent copy of such written
          communication. The Independent Accountants may conduct a conference
          concerning the objections and disagreements between PRG and the
          Stockholders, at which conference each party shall have the right to
          (i) present its documents, materials and other evidence (as previously

                                       5
<PAGE>

          provided to the Independent Accountants and the other parties) and
          (ii) to have present its or their advisors, accountants and/or
          counsel. After affording Stockholders and Stockholders'
          representatives and PRG and PRG's representatives the opportunity to
          present their positions as set forth above, the Independent
          Accountants shall prepare a written report resolving all disputed
          items (the "Independent Accountants' Report") within 30 calendar days
          after the Independent Accountants' engagement letter. Such resolution
          by the Independent Accountants shall be final, conclusive and binding
          upon the parties to this Agreement and shall be reflected in any
          necessary revisions to the Financial Statement and the calculation of
          EBIT. Stockholders and PRG shall direct the Independent Accountants to
          deliver a copy of the Independent Accountants Report directly to the
          Escrow Agent. The Independent Accountants' calculation of EBIT shall
          not exceed the EBIT as determined by the Auditor nor be less than the
          EBIT set forth in the PRG EBIT Proposal. Except for the services to be
          performed by the Independent Accountants under this paragraph, none of
          the parties may hire, contract or solicit the services of the
          Independent Accountants or engage in any conduct with the Independent
          Accountants that could reasonably by expected to compromise the
          Independent Accountants' objectivity and independence. One-half of the
          fees, costs and expenses of the Independent Accountants shall be paid
          by Stockholders and one-half of such fees, costs and expenses shall be
          paid by PRG.

               (e) If EBIT (as finally determined pursuant to this Section 1.5)
          is equal to or greater than One Million Nine Hundred Sixty Thousand
          Dollars ($1,960,000) (the "Target Amount"), the parties shall take all
          necessary action to ensure that the entire Escrow Amount, and all
          accrued interest thereon, is promptly paid by the Escrow Agent to
          Stockholders.

               (f) If EBIT (as finally determined pursuant to this Section 1.5)
          is less than the Target Amount but equal to or greater than One
          Million Seven Hundred Thousand Dollars ($1,700,000) (the "Floor
          Amount"), the Escrow Amount, and accrued interest thereon, shall be
          distributed by the Escrow Agent as follows:

                                       Amount plus fifty percent (50%) of

                                       interest to PRG

               (g) If EBIT (as finally determined pursuant to this Section 1.5)
          is less than the Floor Amount, the entire Escrow Amount, and all
          accrued interest thereon, shall be paid by the Escrow Agent to PRG.

               (h) The parties expressly agree that in the event that the EBIT
          set forth in the PRG EBIT Proposal is equal to or greater than the
          Floor Amount, Stockholders shall be entitled to receive, at the time
          of delivery of the PRG EBIT Proposal and without waiting for final
          determination of EBIT by the Independent Accountants, that portion of
          the Escrow Amount that they would be entitled to receive if EBIT as
          finally determined was equal to the PRG EBIT Proposal.

               (i) All costs of the Escrow Agent will be the responsibility of
          PRG.

          or obligations of Haas or Stockholders thereunder.

          2.4  Capitalization; Title.

          (a) The authorized equity securities of Haas consist of 1,000,000

Thomas J. Van Hercke has an option (the "Van Hercke Option") to acquire 400
additional shares of common stock of Haas (the "Option Shares") upon a change in
control of the ownership of Haas. The Stockholders are and will be on the

issuance, sale or transfer of any equity securities or other securities of Haas.

all meetings held of, and corporate action taken by, the shareholders, the
Boards of Directors, and committees of the Boards of Directors of Haas, and no
meeting of any such shareholders, Board of Directors, or committee has been

minute books. At the Closing, all of those books and records will be in the
possession of Haas.

         2.7 Title to Properties; Encumbrances. Haas does not own any fee
interest in any real property. Part 2.7 of the Disclosure Schedule contains a

          Haas as of the Closing Date in conducting its business and, to the
          Knowledge of Haas and Stockholders, there is no condition which will

          or like matters relating to such Real Property.

               (vi) No Violations. Except as set forth in Part 2.8(b)(vi) of the

          has received no notices, oral or written, from any Governmental Body,
          and Haas and Stockholder have no reason to believe, that the Real

intent and the accuracy of PRG's representations as expressed herein.

of the Facilities or any other properties and assets (whether real, personal or
mixed and whether tangible or intangible) in which Stockholders or Haas has or
had an interest; (ii) any Hazardous Materials or other contaminants that were

allegedly, conducted by Stockholders or Haas or by any other Person for whose

of when any such 


                                       47

<PAGE>


bodily injury occurred, was incurred or manifested itself), personal injury,
property damage (including trespass, nuisance, wrongful eviction and deprivation

employee or former employee of Stockholders or Haas or any other Person for
whose conduct they are or may be held responsible, in any way arising from or
allegedly arising from any Hazardous Activity conducted or allegedly conducted
with respect to the Facilities or the operation of Haas prior to the Closing
Date, or from Hazardous Material that was (i) present or suspected to be present
on or before the Closing Date on or at the Facilities (or present or suspected

10.4 Limitation of Indemnity; Insurance Proceeds. 

(a) PRG shall not seek indemnification for a claim under Section 10.2 unless and
until the aggregate amount of all claims of PRG thereunder is at least equal to
$140,000 (the "Basket Amount"), and then only for the amount of such claims in
excess of the Basket Amount. In addition, the total aggregate liability of
Stockholders under Section 10.2 and Section 10.3 shall in no event exceed fifty
percent (50%) of the sum of the Closing Cash Payment plus the aggregate portion
of the Escrow Amount paid to the Stockholders pursuant to Section 1.5. The
amount of Damages sought by PRG in connection with a claim for indemnification
shall be reduced by the amount, if any, by which taxes actually paid by PRG or
Haas, as the case may be, after giving effect to the payment giving rise to
indemnification hereunder, can reasonably be anticipated to be less than the
taxes that would have 


                                       48

<PAGE>


been paid by PRG or Haas if no such payment had been made. The amount of any
such reduction shall be adjusted, if necessary, based upon the final
determination of the tax liability of PRG or Haas, as the case may be. 

(b) PRG shall not seek or be entitled to indemnification for a claim under
Section 10.2 or 10.3 if each of the following conditions is satisfied: 

(i) PRG determines, in its reasonable discretion, that such claim will be
covered by one or more insurance policies maintained by Haas, and that
submission of such claim will not result in the cancellation of such policy or
policies; and 

(ii) Stockholders agree to indemnify PRG in the event that (x) payment is not
made by the insurer(s) under such policy or policies within a reasonable period
of time, in accordance with standard insurance industry practice, following
submission of such claim, and/or (y) the proceeds of such policy or policies
paid by the insurer(s) thereunder on account of such claim are not sufficient to
satisfy the full amount of Damages arising out of or resulting from such claim,
but such indemnification shall be made only for the uncovered amount. 

10.5 Indemnification and Payment of Damages by PRG. PRG will indemnify and hold
harmless Stockholders, and will pay to Stockholders the amount of any Damages
arising, directly or indirectly, from or in connection with (a) any breach of
any representation or warranty made by PRG in this Agreement or in any
certificate delivered by PRG pursuant to this Agreement, (b) any breach by PRG
of any covenant or obligation of PRG in this Agreement or (c) any claim by any
Person against Stockholders for brokerage or finder's fees or commissions or
similar payments based upon any agreement or understanding alleged to have been
made by such Person with PRG (or any Person acting on its behalf) in connection
with any of the transactions contemplated hereby. 

10.6 Time Limitations. If the Closing occurs, Stockholders will have no
liability (for indemnification or otherwise) with respect to any representation
or warranty, or covenant or obligation to be performed and complied with prior
to the Closing Date, other than those in Sections 2.2, 2.3, 2.4, 2.7, 2.12 and
2.20, unless on or before the first anniversary of the Closing Date, PRG
notifies Stockholders, in writing, of a claim specifying the factual basis of
that claim in reasonable detail to the extent then known by PRG; a claim with
respect to Section 2.2, 2.3, 2.4, 2.7, 2.12 or 2.20, or a claim for
indemnification or reimbursement not based upon any representation or warranty


                                       49

<PAGE>


or any covenant or obligation to be performed and complied with prior to the
Closing Date, may be made at any time; provided however, that a claim under
Section 2.12 or 2.20 may only be made within the applicable statute of
limitations. If the Closing occurs, PRG will have no liability (for
indemnification or otherwise) with respect to any representation or warranty, or
covenant or obligation to be performed and complied with prior to the Closing
Date, unless on or before the first anniversary of the Closing Date,
Stockholders notifies PRG of a claim specifying the factual basis of that claim
in reasonable detail to the extent then known by Stockholders. 

10.7 Procedure for Indemnification--Third Party Claims. 

(a) Promptly after receipt by an indemnified party of notice of the existence or
commencement of any Proceeding or other third party claim against it, such
indemnified party will, if a claim is to be made against an indemnifying party,
give written notice to the indemnifying party of the existence and commencement
of such claim, together with a copy of any documents or pleadings associated
therewith, but the failure to notify the indemnifying party will not relieve the
indemnifying party of any liability that it may have to any indemnified party,
except to the extent that the indemnifying party demonstrates that the defense
of such action is prejudiced by the indemnifying party's failure to give such
notice. 

(b) If any Proceeding or other third party claim is brought against an
indemnified party, or if an indemnified party is subject to or the subject of
any Proceeding, and it gives notice to the indemnifying party of the existence
or commencement of such Proceeding or other third party claim, the indemnifying
party shall have ten (10) days after receipt of the indemnified party's notice
to assume responsibility for such Proceeding or other third party claim with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such Proceeding or other third party claim, the indemnifying party
will not, as long as it diligently conducts such defense, be liable to the
indemnified party under this Article X for any fees of other counsel or any
other expenses with respect to the defense of such Proceeding or other third
party claim, in each case subsequently incurred by the indemnified party in
connection with the defense of such Proceeding. If the indemnifying party
assumes the defense of a Proceeding, (i) there will be a rebuttable presumption
that the claims made in that Proceeding or other third party claim are within
the scope of and subject 


                                       50

<PAGE>


to indemnification, unless a court of competent jurisdiction or such other
competent tribunal determines that such claims are not subject to
indemnification hereunder; (ii) no compromise or settlement of such claims may
be effected by the indemnifying party without the indemnified party's consent,
which consent shall not be unreasonably withheld, unless (A) there is no finding
or admission of any violation of Legal Requirements or any violation of the
rights of any Person and no effect on any other claims that may be made against
the indemnified party and (B) the sole relief provided is monetary damages that
are paid in full by the indemnifying party; and (iii) the indemnified party will
have no liability with respect to any compromise or settlement of such claims
effected without its consent, which consent shall not be unreasonably withheld.

(c) Notwithstanding the foregoing, PRG shall have, at its option and at its cost
and expense (and without the right to seek indemnification from Stockholders
with respect to such cost and expense), the exclusive right to defend the

its right and interest in such uncollected Guaranteed Accounts to Stockholders,
free and clear of any claims or liens (other than and subject to any and all
defenses, counterclaims or rights of set-off that may be asserted by the
customer that do not arise from the actions, other than unsuccessful collection
actions, of Haas or PRG after the Closing Date), and Stockholders shall have the

demanded with respect to such retained accounts. As a condition to the payment
by the Stockholders for the uncollected Guaranteed Accounts, PRG shall cause

Haas, as the case may be, on account of any uncollected Guaranteed Accounts for
which PRG has received payment hereunder.

         13.5 Further Assurances. The parties agree (a) to furnish upon request
to each other such further information, (b) to execute and deliver to each other
such other documents and (c) to do such other acts and things, all as the other
party may reasonably request for the purpose of carrying out the intent of this
Agreement and the documents referred to in this Agreement. 

         13.6 Waiver. The rights and remedies of the parties to this Agreement
are cumulative and not alternative except to the extent otherwise specifically
provided in this Agreement. Neither the failure nor any delay by any party in
exercising any right, power or privilege under this Agreement or the documents

privilege or the exercise of any other right, power or privilege. To the maximum
extent permitted by applicable law, (a) no claim or right arising out of this
Agreement or the documents referred to in this Agreement can be discharged by

right unless in writing signed by the other party; (b) no waiver that may be
given by a party will be applicable except in the specific instance for which it
is given; and (c) no notice to or demand on one party will be deemed to be a
waiver of any obligation of such party or of the right of the party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement. 

         13.7 Entire Agreement and Modification. This Agreement, when executed

(including the letter of intent between PRG and Stockholders dated September 15,
1998 but excluding the Confidentiality Agreement dated February 23, 1998) and
constitutes (along with the documents referred to in this Agreement) a complete
and exclusive statement of the terms of the agreement between the parties with
respect to its subject matter. This Agreement may not be amended except by a
written agreement executed by the party to be charged with the amendment. 

         13.8 Assignments, Successors and No Third Party Rights. Neither party
may assign any of its rights under this Agreement without the prior consent of
the other parties except that PRG may assign any of its rights under this
Agreement to any affiliate of PRG, provided that such assignment will not
relieve PRG of its obligations hereunder. Subject to the preceding sentence,
this Agreement will apply to, be binding in all respects upon, and inure to the
benefit of the successors and permitted assigns of the parties. Nothing
expressed or referred to in this Agreement will be construed to give any Person
other than the parties to this Agreement any legal or equitable right, remedy or
claim under or with respect to this Agreement or any provision of this
Agreement. This Agreement and all of its provisions and conditions are for the
sole and exclusive benefit of the parties to this Agreement and their successors
and assigns. 

         13.9 Severability. If any provision of this Agreement is held invalid
or unenforceable by any court of competent jurisdiction, the other provisions of
this Agreement will remain in full force and effect. Any provision of this
Agreement held invalid or unenforceable only in part or degree will remain in
full force and effect to the extent not held invalid or unenforceable.

require. Unless otherwise expressly provided, the word "including" does not
limit the preceding words or terms.

GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE INTERNAL LAWS
OF THE STATE OF DELAWARE,
