                       STOCK PURCHASE AND SALE AGREEMENT

          THIS STOCK PURCHASE AND SALE AGREEMENT (this "Agreement") entered into

          WHEREAS, the Stockholders desire to sell the Stock to PGI and PGI
desires to purchase the Stock from the Stockholders according to the terms and
provisions of this Agreement (the "Purchase and Sale") so that, following the
Purchase and Sale, ASM will be a wholly-owned subsidiary of PGI;

          NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties, agreements and covenants herein contained, and for
other good and valuable consideration, the receipt and legal sufficiency of
which are hereby acknowledged, the Parties hereby agree as follows:

                                   ARTICLE I
                      THE PURCHASE AND SALE OF THE STOCK

     1.1  The Purchase and Sale of the Stock.
          ---------------------------------- 

          Upon and subject to the terms and conditions of this Agreement, the

     1.2  The Closing.
          ----------- 

          The closing of the transactions contemplated by this Agreement (the
"Closing") shall take place at the offices of James, Denecke & Harris, Portland,

the Parties to consummate the transactions contemplated hereby have not been
satisfied or waived as of the later of the dates in (a) and (b), on such
mutually agreeable later date as soon as practicable after the satisfaction or
waiver of all conditions to the obligations of the Parties to consummate the
transactions contemplated hereby, provided, however, in no event shall ASM or
the Stockholders be required to consent to a Closing Date later than March 15,
1997.

     1.3  Actions at the Closing.
          ---------------------- 

          At the Closing, (a) the Stockholders shall deliver to PGI all stock
certificates representing the Stock, which shall be all of the issued and

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

          PGI may, at any time after the Closing, take any action, including
executing and delivering any document, in the name and on behalf of ASM, in
order to consummate the Purchase and Sale contemplated by this Agreement.

     1.5  Purchase Consideration.
          ---------------------- 

          The purchase consideration (the "Purchase Consideration") to be paid
by PGI shall be the sum of the Base Purchase Consideration (as hereinafter
defined) and the Additional Purchase Consideration (as hereinafter defined).
The Purchase Consideration shall be paid to the Stockholders when due by wire
transfer of immediately available funds to an account or accounts designated in
writing by the Stockholder Representative (as hereinafter defined) to PGI not
less than three days prior to the date on which any such payment is due.  The
Purchase Consideration shall be allocated to the Stockholders on a pro rata
basis in accordance with the number of shares of Stock owned by each
Stockholder, and shall be characterized on the tax returns of each Party as
provided in Section 1.7 hereof.

          (a) Base Purchase Consideration - PGI shall (i) pay the sum of Twenty
              ---------------------------                                      
Million Dollars ($20,000,000) (the "Base Purchase Consideration") at the Closing
in the manner set forth above in this Section 1.5; and (ii) issue to
Stockholders 10,000 shares of PGI Common Stock, par value $.01 per share, free
and clear of all liens and encumbrances.  The Base Purchase Consideration shall
be subject to adjustment as set forth in Section 1.5(b) below.


                                       2

 
          (b) Adjustment to Base Purchase Consideration.
                   ----------------------------------------- 

              (i) Within 75 days after the Closing Date, PGI shall cause its
accountants to prepare and shall deliver to Stockholders unaudited financial
statements of ASM as of the Closing Date and for the period from the date of the
Most Recent Balance Sheet (as defined in Section 2.8 hereof) through the Closing
Date (the "Closing Financial Statements"). The Closing Financial Statements
shall be prepared in accordance with generally accepted accounting principles
(on an accrual basis of accounting) from all books, records and accounts of ASM.
Such Closing Financial Statements shall be prepared using the same accounting
policies as those used to prepare the financial statements as of November 30,
1996 and for the eleven months then ended. The retained earnings (deficit)
balance, derived from the Closing Financial Statements, less any fixed assets or
intangible assets purchased during the period from November 30, 1996 to the date
of the Closing Financial Statements (unless such purchase was approved by PGI
pursuant to Section 4.3(a) hereof, or otherwise in writing) (the "Adjusted
Retained Earnings (Deficit)"), shall provide the basis for determining the
adjustment to the purchase price described in the following paragraphs. A detail
listing of accounts receivable by customer and amount as of the Closing Date
should be provided to PGI.

              (ii) Stockholders and their representatives shall have the right
to review all work papers and procedures used to prepare the Closing Financial
Statements and shall have the right to perform any other reasonable procedures
necessary to verify the accuracy thereof. Unless Stockholders, within 30 days
after delivery to Stockholders of the Closing Financial Statements, notify PGI
in writing that they object to the Closing Financial Statements, and specify the
basis for such objection, such Closing Financial Statements shall become final,
binding and conclusive upon the parties for purposes of this Agreement. If
Stockholders and PGI are unable to resolve any objections to the Closing
Financial Statements within ten days after any such notification has been given,
the dispute shall be referred to Price Waterhouse LLP (the "Designated
Accountant") for resolution (or, if the Designated Accountant is unavailable, to
another nationally recognized public accounting firm mutually agreed upon by
Stockholders and PGI within five days from the date upon which the Designated
Accountant notifies the parties that it is not available). If PGI and
Stockholders are unable to agree upon the designation of such an accounting firm
within such five-day period, then either party may, within three days
thereafter, request that the President of the American Arbitration Association
make such designation. The Designated Accountant or the accounting firm
designated hereunder will make a determination as to each of the items in
dispute and shall notify the Parties of such determination within 30 days after
referral of the dispute to such accountant hereunder, which determination shall
be final, conclusive and binding upon each of the Parties hereto. PGI and
Stockholders shall cooperate with each other and with each other's authorized
representatives in order to resolve any and all matters in dispute under this
Section 1.5(b) as quickly as practicable and shall share the fees and expenses
of the Designated Accountant equally.

              (iii) If the Adjusted Retained Earnings (Deficit) of ASM as set
forth on the balance sheet included in the Closing Financial Statements is less
than zero dollars, then the Base Purchase Consideration shall be decreased
dollar for dollar by the amount by which such retained earnings (deficit) is
less than zero dollars (the "Base Purchase Consideration Reduction").
Stockholders shall remit the amount of such Base Purchase Consideration

                                       3

 
Reduction, with interest, to PGI within five days after finalization of the
Closing Financial Statements as set forth above. Interest for purposes of this
Section 1.5(b)(iii) and of Section 1.5(b)(iv) hereof shall be calculated at the
rate of 8% per annum.


              (iv) If the Adjusted Retained Earnings (Deficit) of ASM as set
forth on the balance sheet included in the Closing Financial Statements is
greater than zero dollars, then the Base Purchase Consideration shall be
increased dollar for dollar by the amount by which such retained earnings
(deficit) is greater than zero dollars (the "Base Purchase Consideration
Increase"). PGI shall remit the amount of such Base Purchase Consideration
Increase, with interest, to Stockholders within five days after finalization of
the Closing Financial Statements as set forth above.

          (c) Additional Purchase Consideration for 1997 - If applicable, PGI
              ------------------------------------------                     
shall pay to Stockholders the following additional sum (the "1997 Additional
Purchase Consideration") in the manner set forth below:

              (i) As used in this Section 1.5, "Pre-Tax, Pre-Executive
Compensation Net Income" or "PTPECNI" for the period in question (the
"Applicable Period") shall mean the difference between Total Revenues (as
hereinafter defined) for the Applicable Period less Expenses (as hereinafter
defined) for the Applicable Period. For purposes of calculation of PTPECNI,
"Total Revenues" shall mean all cash revenues of the Existing ASM Business (as
hereinafter defined) based on a calendar year accounting, including, without
limitation, all advance deposits received by ASM. For purposes of calculation of
PTPECNI, "Expenses" shall mean all expenses paid by ASM in the Applicable Period
(inclusive of advance expenses on shows), exclusive of (A) management fees or
other corporate expenses paid to PGI and not directly attributable to the
Existing ASM Business, (B) executive compensation paid to John Inglis or
Kearney, (C) extraordinary expenses, including professional fees and the costs
of the transaction contemplated under this Agreement, (D) interest expense,
income or other taxes. As used in this Section 1.5, "Existing ASM Business"
shall mean all business of ASM existing as of the date hereof, and all business
of ASM commenced after the date hereof other than business of ASM that (I)
competes directly or indirectly with any activity of PGI, (II) requires a
significant capital investment by PGI, (III) is outside the area of expertise of
ASM at the time of implementation, (IV) requires for implementation the addition
of staff or expertise by ASM not possessed by ASM as of the date hereof, or (V)
is conducted by a subsidiary or division of PGI included in the operations of
ASM by PGI (such ASM business commenced after the date hereof and satisfying the
conditions set forth in clauses I, II, III, IV or V above shall be separately
referred to as "New ASM Business"), provided, however, that any New ASM Business
                                    --------  -------
subject to the exclusions set forth in clauses (I), (II), (III) (IV) or (V)
immediately above shall be included in the definition of Existing ASM Business
upon the written approval of the Chief Executive Officer of PGI. As used in this
Section 1.5, "Profit Margin" shall mean the percentage that results from
dividing PTPECNI of the Existing ASM Business generated during any calendar year
by the amount of Total Revenues generated by the Existing ASM Business during
such calendar year.

              (ii) (A) On or before 30 days following the end of March, June,
September and December of 1997, PGI shall prepare a quarterly unaudited internal
calculation (each, a "Quarterly Earn-Out Estimate") to determine whether any
1997 Additional



                                       4

 
Purchase Consideration has been earned in 1997 prior to or during such quarter.
On or before April 30, 1998, PGI shall deliver to Stockholders a statement (the
"Final Quarterly 1997 Earn-Out Statement") setting forth whether any 1997
Additional Purchase Consideration has been earned during calendar year 1997.

                  (B) If (x) PTPECNI for year-to-date 1997 as set forth in a
Quarterly Earn-Out Estimate or Final Quarterly 1997 Earn-Out Statement, as the
case may be, is greater than the year to date PTPECNI target (the "Year To Date
PTPECNI Target") listed in Table 1 below and (y) the Profit Margin for year-to-
                           -------                          
date 1997 as of the end of such quarter is equal to or greater than  *  , then
PGI shall pay to the Stockholders in the manner set forth below an amount equal
to  * of the amount by which (I) PTPECNI for year-to-date 1997 exceeds (II)
the Year to Date PTPECNI Target in Table 1 below, reduced by any 1997 Additional
                                   -------                        
Purchase Consideration paid previously.

                  (C)     Table 1 is as follows:

              (iii) Stockholders and their representatives shall have the right
to review all work papers and procedures used to prepare the Final Quarterly
1997 Earn-Out Statement and shall have the right to perform any other reasonable
procedures necessary to verify the accuracy thereof. Unless Stockholders, within
30 days after delivery to Stockholders of the Final Quarterly 1997 Earn-Out
Statement, notify PGI in writing that they object to the Final Quarterly 1997
Earn-Out Statement, and specify the basis for such objection, such Final
Quarterly 1997 Earn-Out Statement shall become final, binding and conclusive
upon the Parties for purposes of this Agreement. If the Parties are unable to
resolve any objections to the Final Quarterly 1997 Earn-Out Statement within ten
days after any such notification has been given, PGI shall pay to the
Stockholders any undisputed amount of 1997 Additional Purchase Consideration and
the dispute shall be referred to Designated Accountant for resolution (or, if
the Designated Accountant is unavailable, to another nationally recognized
public accounting firm mutually agreed upon by Stockholders and PGI within five
days from the date upon which the Designated Accountant notifies the parties
that it is not available). Within 30 days the Designated Accountant will make a
determination as to each of the items in dispute, which determination shall be
final, conclusive and binding upon each of the Parties hereto, provided,
however, that if the amount of the dispute shall exceed $100,000, any Party that
disputes the Designated Accountant's determination may submit the matter for
binding arbitration in accordance with Section 8.15 hereof. PGI and the
Stockholders shall cooperate with each other and with each other's authorized
representatives in order to resolve any and all matters in dispute under this
Section 1.5(c) as soon as practicable, and each of PGI and the Shareholders
shall pay half of the fees and

                                       5

 
expenses of the Designated Accountant or of arbitration. The total amount of
1997 Additional Purchase Consideration owed to Stockholders hereunder shall be
the amount set forth on the Final Quarterly 1997 Earn-Out Statement as
determined in accordance with this Section 1.5(c)(iii) (the "Final 1997 Earn-Out
Amount").

              (iv) On the Closing Date, PGI shall deposit   *    (the "Initial
Additional Purchase Consideration Amount") to an account maintained by the
Stockholders (the "Additional Purchase Consideration Account"). The Additional
Purchase Consideration Account shall be maintained by the Stockholders at United
States National Bank, Portland, Oregon (the "Designated Bank"). The Additional
Purchase Consideration Account (A) shall require for withdrawal the signature of
John Inglis as Stockholder Representative and the Chief Executive Officer of PGI
or his designee; and (B) shall be interest bearing with all interest paid to
PGI. Any 1997 Additional Purchase Consideration shown to be owed on any
Quarterly Earn-Out Estimate in excess of the Initial Additional Purchase
Consideration Amount shall be paid by PGI into the Additional Purchase
Consideration Account within 45 days following the end of the calendar quarter.
Notwithstanding the withdrawal mechanism set forth above, all funds in the
Additional Purchase Consideration Account shall be the sole and exclusive
property of the Stockholders. Any failure of the Stockholder Representative to
approve an authorized withdrawal as set forth herein shall constitute the breach
of a material covenant pursuant to this Agreement subject to the Stockholder
indemnification obligations as set forth herein.

              (v) Withdrawals shall be permitted from the Additional Purchase
Consideration Account as follows:

                  (A) To PGI, following the preparation of the Quarterly Earn-
Out Estimate for the third quarter of 1997 or the Final Quarterly 1997 Earn-Out
Statement: (i) in the event that PTPECNI for year-to-date 1997 as set forth in
the Quarterly Earn-Out Estimate for the third quarter of 1997 or Final Quarterly
1997 Earn-Out Statement, as the case may be, is equal to or less than the Year
To Date PTPECNI Target listed in Table 1 above, or (ii) in the event that the
                                 -------                                     
Profit Margin for year-to-date 1997 is less than  *  ; in either of which events
PGI shall be entitled to receive the full amount in the Additional Purchase
Consideration Account.

                  (B) To PGI, to the extent of the excess of any amount in the
Additional Purchase Consideration Account over the Final 1997 Earn-Out Amount.

                  (C) To Stockholders, to pay the Final 1997 Earn-Out Amount.

                  (D) To PGI, on or before September 30, 1997, to reimburse PGI
for up to an aggregate of $250,000 of any Hall Contract Losses (as defined in
Section 7.2(e) hereof) in the event that the Stockholders do not pay the full
amount of any Hall Contract Loss (up to $250,000) within 30 days following
notice from PGI.

                  (E) To Stockholders, in the event an Accelerated Earn-Out
Event occurs.

              (vi) PGI shall be obligated to pay Stockholders any amount of the
Final 1997 Earn-Out Amount in excess of the amount in the Additional Purchase
Consideration Account within 10 days following determination of the Final 1997
Earn-Out Amount in accordance with Section 1.5(c)(iii) hereof.

          (d) Additional Purchase Consideration for 1998 - If applicable, PGI
              ------------------------------------------                     
shall pay to Stockholders the following additional sum (the "1998 Additional
Purchase Consideration") in the manner set forth below (the 1997 Additional
Purchase Consideration and the 1998 Additional Purchase Consideration shall be
collectively referred to herein as the "Additional Purchase Consideration"):

              (i) (A) On or before 30 days following the end of March, June,
September and December of 1998, PGI shall prepare a Quarterly Earn-Out Estimate
to determine whether any 1998 Additional Purchase Consideration has been earned
in 1998 prior to or during such quarter. On or before April 30, 1999, PGI shall
deliver to Stockholders a statement (the "Final Quarterly 1998 Earn-Out
Statement") setting forth whether any 1998 Additional Purchase Consideration has
been earned during calendar year 1998.


                  (B) If (x) PTPECNI for year-to-date 1998 as set forth in a
Quarterly Earn-Out Estimate or Final Quarterly 1998 Earn-Out Statement, as the
case may be, is greater than the Year To Date PTPECNI Target set forth in (C)
below and (y) the Profit Margin for year-to-date 1998 is equal to or greater
than  *  , then PGI shall pay to the Stockholders in the manner set forth below
an amount equal to  *   of the amount by which (I) PTPECNI for year-to-date 1998
exceeds (II) the Year to Date PTPECNI Target set forth in (C) below, reduced by
any 1998 Additional Purchase Consideration paid previously.

                  (C)  (a)  Table 2 is as follows:

          (b) Notwithstanding the amounts set forth for Year to Date PTPECNI

for such target set forth in Table 2 and actual quarterly PTPECNI for 1997 as

set forth on the Final Quarterly 1997 Earn-Out Statement.

              (ii) Stockholders and their representatives shall have the right
to review all work papers and procedures used to prepare the Final Quarterly
1998 Earn-Out Statement and shall have the right to perform any other reasonable
procedures necessary to verify the accuracy thereof. Unless Stockholders, within

Statement, notify PGI in writing that they object to the Final Quarterly 1998
Earn-Out Statement, and specify the basis for such objection, such Final

days after any such notification has been given, PGI shall pay to the
Stockholders any undisputed amount of 1998 Additional Purchase Consideration and
the dispute shall be referred to the Designated Accountant for resolution.
Within 30 days the Designated Accountant will make a determination as to each of
the items in dispute, which determination shall be final, conclusive and binding
upon each of the Parties hereto, provided, however, that if the amount of the
dispute shall exceed $100,000, any Party that disputes the Designated
Accountant's determination may submit the matter for binding arbitration
pursuant to Section 8.15 hereof.  PGI and the Stockholders shall cooperate with
each other and with each other's authorized representatives in order to resolve
any and all matters in dispute under this Section 1.5(d) as soon as practicable,
and each of PGI and the Shareholders shall pay half of the fees and expenses of
the Designated Accountant or of arbitration.  The total amount of 1998
Additional Purchase Consideration owed to Stockholders hereunder shall be the
amount set forth on the Final Quarterly 1998 Earn-Out Statement as determined in
accordance with this Section 1.5(c)(ii) (the "Final 1998 Earn-Out Amount").

              (iii) Any 1998 Additional Purchase Consideration shown to be owed
on any Quarterly Earn-Out Estimate shall be paid by PGI into the Additional
Purchase Consideration Account within 45 days following the end of the calendar
quarter. Notwithstanding the withdrawal mechanism set forth in Section
1.5(c)(iv) above, all funds in the Additional Purchase Consideration Account
shall be the sole and exclusive property of the Stockholders. Any failure of the
Stockholder Representative to approve an authorized withdrawal as set forth
herein shall constitute the breach of a material covenant pursuant to this
Agreement subject to the Stockholder indemnification obligations as set forth

              (iv) Withdrawals shall be permitted from the Additional Purchase
Consideration Account as follows:

                  (A) To PGI, following the preparation of the Quarterly Earn-

year-to-date 1998 is less than  *  ; in either of which events PGI shall be
entitled to receive the full amount in the Additional Purchase Consideration
Account.

                  (B) To PGI, any remaining amount after the payment provided
for in Section 1.5(d)(iv)(C) below.

              (v) PGI shall be obligated to pay Stockholders any amount of the
Final 1998 Earn-Out Amount in excess of the amount in the Additional Purchase
Consideration Account within 10 days following determination of the Final 1998
Earn-Out Amount in accordance with Section 1.5(d)(ii) hereof, and thereafter
shall have no further responsibility under this Section 1.5.

          (e) Calculation Matters.  For purposes of the calculation of 1997
              -------------------                                          
Additional Purchase Consideration and 1998 Additional Purchase Consideration,
PTPECNI and Profit Margin shall be calculated on a cash basis in a manner
consistent with the Business Plan (as hereinafter defined).  Promptly following
the Closing, PGI and the Stockholders shall negotiate in good faith to establish
calculation principles on an accrual basis consistent with PGI's current
accounting methods.  For purposes of the comparison of PTPECNI generated during
any present and prior calendar year, if PGI shall have expanded the scope of the
Existing ASM Business by the addition of a new business line or activity or any
New ASM Business to ASM in the present calendar year that shall have resulted in
a change in the amount of PTPECNI during such calendar year, the PTPECNI dollar
target and Profit Margin set forth above for calculation of Additional Purchase
Consideration shall be increased or decreased on a pro rata basis with respect
to such change.  Stockholders acknowledge and agree that the Executive Committee
of the Board of Directors of PGI shall have unrestricted authority to exercise
its independent business judgment with regard to the affairs of ASM after the
Closing, including, without limitation, decisions with respect to appropriate
charges to ASM for expenses incurred by ASM, decisions as to expansion, if any,
and decisions as to ASM's business or redeployment of its assets, provided,
however, that material alterations in the allocation of expenses to ASM shall be
reasonable and shall be generally consistent with the business plan agreed to
among the Parties, as supplemented pursuant to Section 1.8 hereof (the "Business
Plan"), which is set forth as Section 1.5(e) of the disclosure schedule attached
                              --------------                                    
hereto (the "Disclosure Schedule").  In calculating the amount of Additional
Purchase Consideration earned in 1997 or 1998, PGI shall make reference to the
Business Plan and the amount of Additional Purchase Consideration projected
thereunder.

          (f) Stockholder Representative.  The Stockholders hereby appoint John
              --------------------------                                       
Inglis as their representative (the "Stockholder Representative") for all
matters relating to this Agreement and the Purchase and Sale transaction,
including, without limitation, for purposes of the calculation of Additional
Purchase Consideration and for purposes of indemnification matters under Article
VII hereof.  PGI may rely on all agreements reached with the Stockholder
Representative on behalf of the Stockholders, and all such agreements entered
into with such Stockholder Representative shall be final and binding on
Stockholders.  The Stockholder Representative also shall be responsible for the
appropriate allocation of Purchase Consideration among the Stockholders.

     1.6  Treatment of Stock.
          ------------------ 

          From and after the Closing, all of the capital stock of ASM shall be
held by PGI.

     1.7  Certain Tax Matters.
          ------------------- 

          (a) The Parties acknowledge that the Purchase and Sale of the Stock of
ASM will constitute a "qualified stock purchase" for purposes of Section
338(d)(3) of the Internal Revenue Code (the "Code") and that PGI intends to make
an "express election" pursuant to Section 338(g) of the Code and the regulations
thereunder with respect to each such Purchase and Sale.  Stockholders warrant to
Purchaser that they are qualified to make a valid election under Section
338(h)(10) of the Code and Section 1.338(h)(10)-1(d)(1) of the Income Tax
Regulations with respect to such purchase.  Stockholders and PGI agree to join
in making a valid election under Section 338(h)(10) of the Code with respect to
such purchase.  Stockholders and PGI also agree to make the state law equivalent
of the Section 338(h)(10) election wherever such election is available.  PGI
shall prepare Forms 8023 and submit them to Stockholders for signing.  PGI and
Stockholders shall fully cooperate in making the elections under Section
338(h)(10) of the Code and similar available elections pursuant to applicable
state and local laws.  The Parties agree to allocate the deemed purchase price
of the assets of ASM pursuant to the procedures in Section 1.7(g) below.  In
connection with the foregoing, ASM and the Stockholders shall cause Perkins &
Company to provide appropriate PGI personnel with the information needed to
invoke the necessary and appropriate tax elections.

          (b) Stockholders shall pay or cause to be paid all taxes (hereinafter,
"Election Taxes") arising as a result of the elections under Sections 338(g) and
338(h)(10) of the Code, or comparable provisions of state and local law,
provided, however, that if the Stockholders shall be required to pay a greater
amount of tax as a result of such elections than the Stockholders would have
been required to pay in connection with the transaction contemplated hereby had
no such elections been made, then PGI shall reimburse the Stockholders an amount
equal to the excess of (i) the lesser of (A) the federal income tax amount
resulting from such election or (B) the federal income tax amount that would
have resulted from such election if ASM had qualified as an S corporation at all
times from the date of its formation through the opening of business on the
Closing Date over (ii) the federal income tax amount that would have resulted in
the absence of such election.

          (c) Stockholders and PGI shall cooperate fully with each other and
make available or cause to be made available to each other in a timely fashion
such tax data, prior tax returns and filings and other information as may be
reasonably required for the preparation by PGI or Stockholders of any tax
returns, elections, consents or certificates required to be prepared and filed
by PGI or Stockholders and any audit or other examination by any taxing
authority, or judicial or administrative proceeding relating to liability for
Election Taxes.  Purchaser and Stockholders will each retain and provide to the
other party all records and other information which may be relevant to any Tax
Return (as defined in Section 2.9 hereof), audit or examination, proceeding or
determination, and will each provide the other Party with any final
determination of any such audit or examination, proceeding or determination that
affects any amount required to be shown on any Tax Return of the other Party for
any period.  Without limiting the generality of the foregoing, each of PGI and
Stockholders will retain copies of all Tax Returns, supporting work schedules
and other records relating to tax periods or portions thereof ending prior to or
on the Closing Date.  PGI will cause appropriate personnel to prepare usual and
customary tax return packages for (i) the tax period ending December 31, 1997
(the "1997 Packages") and (ii) the tax 


                                      10

 
period beginning as of January 1, 1997, and ending as of the Closing Date (the
"Short Period Packages") (collectively, a "Package" or the "Packages"). Except
as otherwise provided below, the 1997 Packages will be delivered to Stockholders
not later than June 1, 1998 and the Short Period Packages will be delivered to
Stockholders not later than 120 days after the Closing Date. If PGI cannot
deliver the Packages on or before the prescribed times without incurring
additional out-of-pocket expenses, it may notify Stockholders of that fact not
later than 30 days prior to the prescribed date of delivery of such Package. If
Stockholders agree to reimburse PGI for the additional out-of-pocket expenses of
timely delivery of the Packages, then PGI shall deliver the Packages at the
times prescribed herein. If Stockholders does not agree to reimburse PGI for the
additional out-of-pocket expenses of timely delivery of the Packages, PGI shall
deliver the Packages to Stockholders as soon after the initially prescribed
times as is reasonably practicable, PGI having no obligation to incur additional
out-of-pocket expenses to accelerate the delivery. PGI will provide Stockholders
with any necessary payroll records attributable to the period prior to the
Closing Date.

          (d) Any sales, transfer, use or other similar taxes imposed as a
result of the sale of the Stock to PGI pursuant to this Agreement shall be borne
by Stockholders.  At the Closing, PGI shall remit to Stockholders such properly
completed resale exemption certificates and other similar certificates or
instruments as are necessary to claim available exemptions from the payment of
sales, transfer, use or other similar taxes under applicable law.  All
recording, transfer and other similar taxes and fees payable as a result of the
public recordation of the instruments of conveyance or transfer of the Stock
executed and delivered to PGI pursuant to this Agreement shall be allocated
between the PGI and the Stockholders in accordance with the customary practice
prevailing in Oregon.

          (e) Stockholders shall be responsible for, and shall indemnify and
hold harmless, PGI and its officers, directors and shareholders in respect of
any damages attributable to all Election Taxes with respect to the ownership or
operation of ASM on or prior to the Closing Date and PGI or its affiliates shall
be responsible for, and shall indemnify and hold harmless Stockholders and their
affiliates in respect of any damages attributable to all Election Taxes with
respect to the ownership or operation of ASM after the Closing Date.
Stockholders' share of all real and personal property taxes, state and local ad
valorem taxes and assessments applicable to ASM for any period commencing on or
prior to the Closing Date and ending after the Closing Date shall be determined
on a pro rata basis based on the length of such period and when the Closing Date
occurs therein.

          (f) Stockholders and PGI agree that the Purchase and Sale contemplated
by this Agreement constitutes a sale of a trade or business within the meaning
of Section 41(f)(3) of the Code.  Stockholders agree to provide PGI upon request
with all information necessary to permit PGI to timely apply the provisions of
Section 41(f)(3)(A) of the Code with respect to ASM.  Stockholders agree to
furnish PGI upon request clearance certificates or similar documents that may be
required by any state, local or other taxing authority to relieve PGI of any
obligations to withhold any portion of the purchase consideration to be
transferred pursuant to this Article I.


                                      11

 
          (g) The Purchase Consideration, including the Base Purchase
Consideration and the Additional Purchase Consideration, if any, shall be
allocated among the assets of ASM as provided in Section 338 of the Code and the
Treasury Regulations thereunder, which allocation is as set forth on Schedule
                                                                     --------
1.7(g) attached hereto (which Schedule shall be completed by the Parties prior
- ------                                                                        
to the Closing).  PGI and ASM each agree to file Form 8594 and any other
relevant income tax returns and reports in a manner consistently reflecting the
allocations set forth on Schedule 1.7(g).  Stockholders agree to provide PGI and
                         ---------------                                        
its representatives (including without limitation the appraiser) reasonable
access to the assets and records of Stockholders prior to the Closing.  PGI and
Stockholders shall not take any position on their respective Tax Returns that is
inconsistent with such allocation of the Purchase Consideration, and PGI and
Stockholders shall duly prepare and timely file such reports and information
returns as may be required to report the allocation of the Purchase
Consideration pursuant to this Section 1.7(g).  The Parties acknowledge that the
Purchase Consideration subject to allocation will be different amounts for each
of PGI and Stockholders (e.g., due to inclusion of differing amounts of
transaction costs).

          (h) In the event any taxing authority mistakenly delivers to or
otherwise credits PGI with a refund relating to taxes paid or arising in periods
prior to the Closing Date, PGI will promptly negotiate such refund to
Stockholders or pay an amount equal to such credit to Stockholders, as the case
may be.

     1.8  Business Plan.
          ------------- 

          After Closing, the Stockholders will have an interest in ASM
represented by the right to receive 1997 Additional Purchase Consideration and
the 1998 Additional Purchase Consideration, if any, as provided herein.  In
order to (a) provide for an orderly integration of the Business into the
operations of PGI and (b) protect the Stockholders' opportunity to receive
Additional Purchase Consideration, PGI agrees that PGI will subscribe to the
Business Plan for the operation of ASM during the period beginning on the
Closing Date and continuing until the end of calendar year 1998.  The Business
Plan for calendar year 1997 is attached hereto as Section 1.5(e) of the
                                                  --------------       
Disclosure Schedule and expresses the general intent for the business operations
and objectives of ASM in such calendar year 1997.  No later than December 1,
1997, the Stockholders shall submit a supplemented Business Plan that shall
address calendar 1998 and that shall provide a reasonable plan for achieving the
PTPECNI target set forth in Section 1.5(d) hereof, which supplemental Business
Plan shall be subject to the review and approval (which approval shall not be
unreasonably withheld) of the Executive Management Team of PGI.  During calendar
years 1997 and 1998, the Parties will conduct themselves in substantial
accordance with the Business Plan, provided, however, that PGI shall have the
right to alter the Business Plan if PGI determines, in the reasonable exercise
of its discretion and following reasonable consultation and discussion with the
Stockholder Representative, that continuing to operate ASM in accordance with
the Business Plan as then drafted is not likely to achieve the targets or
objectives set forth in the Business Plan or that changed business conditions
make such alteration advisable.  Notwithstanding the foregoing, if PGI changes
the Business Plan in a manner that causes the Stockholders to receive less
Additional Purchase Consideration than they would have received without such
change, then PGI and the Stockholder Representative shall negotiate in good
faith to 


                                      12

 
reach mutual agreement concerning an equitable adjustment to the calculation
principles with respect to Additional Purchase Consideration in the future.

connection with such negotiation.

          (b) Each of the Stockholders has personal knowledge of the daily
operations of ASM by virtue of such Stockholder's present and prior affiliation

$100 million or more in annual sales, and ASM's most recent regularly prepared
balance sheet does not show $100 million or more in total assets.  In addition,
there are no persons or other entities (including, for purposes hereof, (a) any
shareholder of ASM that, together with all other entities included within the
same person as that shareholder, either holds 50% or more of ASM's voting
securities or is currently entitled by contract to appoint 50% or more of ASM's
directors, (b) any entity of which ASM holds 50% or more of the voting
securities, or has the current ability to appoint 50% of the board of directors
(or individuals exercising similar functions for those entities without
directors), or (c) any entity of which ASM is entitled to either 50% of the
profits or 50% of the assets on dissolution) that, if analyzed in combination
with ASM, would cause ASM's most recent annual statement of income and expense
to show $100 million or more in annual sales or ASM's most recent regularly
prepared balance sheet to show $100 million or more in total assets.

authorized by the necessary corporate action on the part of PGI.  This Agreement
has been duly and validly executed and delivered by PGI and, assuming the due
authorization, execution and delivery by ASM and the Stockholders, constitutes a
valid and binding obligation of PGI, enforceable against it in accordance with
its terms, except as enforcement may be limited by bankruptcy, insolvency or
other similar laws affecting the enforcement of creditors' rights and remedies
generally, and except that the availability of equitable remedies, including
specific performance, is subject to the discretion of the court before which any
proceeding therefor may be brought.

Agreement, or in connection with the registration statement filed or to be filed
in connection with PGI's Public Offering (the "Registration Statement"),
contains or will contain any untrue statement of a material fact or omits or

consummation of the Purchase and Sale, and to cause PGI to be listed on the
NASDAQ stock exchange in connection with such Public Offering.  PGI shall not
grant a security interest in the proceeds of the Public Offering such that PGI
shall be unable to pay the Base Purchase Consideration to the Stockholders when
due under this Agreement.

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

          PGI represents and warrants that, to the best of PGI's knowledge, PGI
is not in breach of any covenant applicable to PGI under any senior secured all-
asset financing or lending commitment extended to PGI, and that all such
financing arrangements in favor of PGI are legal, valid and enforceable and in
full force and effect with respect to PGI, and to PGI's knowledge such financial
arrangements are legal, valid, binding and enforceable and in full force and
effect with respect to each other party thereto (except as enforcement may be
limited by bankruptcy, insolvency or other similar laws affecting the
enforcement of creditors' rights and remedies generally).  PGI has no knowledge
of any event that has occurred that is, or that with notice or the passage of
time would be, any default under any financing or lending commitment to which
PGI is a party.

1.5(b)(iii) to be required.

     4.4  Full Access.
          ----------- 

          Between the date hereof and the Closing, ASM shall permit PGI and its

deemed waived by reason of the fact that any of PGI, its counsel, its
accountants, its auditors or its other representatives and advisors know or
discover or should have known or discovered that any such representation or
warranty is or might be inaccurate in any respect, whether as a result of such
access or otherwise.

     4.5  Notice of Breaches.
          ------------------ 

          ASM shall promptly deliver to PGI written notice of any event or
development that would (a) render any statement, representation or warranty of
ASM in this Agreement (including the Disclosure Schedule) inaccurate or
incomplete in any material respect, or (b) constitute or result in a breach by
ASM or any of its Affiliates of, or a failure by ASM or any of its Affiliates to
comply with, any agreement or covenant in this Agreement applicable to such
party.  PGI shall promptly deliver to ASM written notice of any event or
development that would (i) render any statement, representation or warranty of
PGI in this Agreement inaccurate or incomplete in any material respect, or (ii)
constitute or result in a breach by PGI of, or a failure by PGI to comply with,
any agreement or covenant in this Agreement applicable to such party.  No such
disclosure shall be deemed to avoid or cure any such misrepresentation or
breach.

     4.6  Exclusivity.
          ----------- 

          ASM and the Stockholders covenant and agree that neither ASM, the
Stockholders, nor any of ASM's officers, directors, employees, agents or
representatives (including, without limitation, any investment banker, attorney
or accountant retained by it) will, 



                                      35

 
directly or indirectly, initiate, solicit, entertain or negotiate, or approve,

if the Purchase and Sale is consummated, ending on the Closing Date.

     4.7  Confidentiality.
          --------------- 

          Each of the parties hereto agrees that it shall, and shall cause its
subsidiaries and the officers, employees and authorized representatives of each
of them to, hold in strict confidence all data and information obtained by them
from the other parties hereto (unless such information is or becomes readily
ascertainable from public or published information) and shall not, and shall use
its best efforts to ensure that such subsidiaries, directors, officers,
employees and authorized representatives do not, disclose such information to
others without the prior written consent of the party from which such data or
information was obtained, except as required by law after consultation with
counsel (provided that any such party shall consult with the other party prior
to making such disclosure).  In the event that this Agreement terminates without
the Purchase and Sale having taken place, the Parties and their respective
affiliates and agents:  (a) shall hold in confidence and refrain from using all
non-public information received in connection with the transactions contemplated
in this Agreement; and (ii) either shall return promptly all such non-public
information to the Party to which such information relates or shall destroy such
documents, work papers and other materials (including all copies made thereof)
obtained pursuant hereto, at such Party's request.

     4.8  Covenant Not to Disclose.
          ------------------------ 

          (a) ASM and the Stockholders acknowledge and agree that ASM and the
Stockholders possess certain data and knowledge of operations of the business
conducted by ASM prior to the Closing Date (the "Business") which are
proprietary in nature and confidential, including, without limitation, certain
trade secrets (the "Trade Secrets").  ASM and the Stockholders jointly and
severally covenant and agree that, except as agreed between PGI and
Stockholders, neither ASM nor the Stockholders will, at any time after the
Closing, reveal, divulge or make known to any Person (other than PGI or ASM) or
use for its or his or her own account or for the account of any Person, any
confidential or proprietary methods, record, data, Trade Secret, pricing policy,
bid amount, bid strategy, rate structure, personnel policy, method or practice
of soliciting or obtaining or doing business by the Business, or any other
confidential or proprietary information whatsoever relating to the Business or
ASM or PGI or their affiliates, whether or not obtained with the knowledge and
permission of ASM or PGI or their affiliates.

          (b) ASM and the Stockholders will, following the Closing, maintain the
Trade Secrets as confidential and proprietary information of ASM in the manner
maintained prior to the Closing.  ASM and the Stockholders have no knowledge of
any other persons or entities who have written copies of information relating to
the Trade Secrets.  ASM has previously delivered to PGI copies of agreements of
confidentiality executed by employees of the ASM.



                                      36

 
     4.9  Non-Compete.
          ----------- 

          (a) When used in this Section 4.9, the following terms shall have the
following meanings:

          "Competition" means (i) the marketing, development, sale or offering
or promoting for sale of (A) any activities or services of the type that ASM or
PGI currently provides, and (B) shows within the same industries as shows
conducted by ASM or PGI as of the Closing Date; and (ii) any business which is
competitive with the Business or the business or operations of PGI as they are
now or hereafter operated during the period in which the respective individual
Stockholder is in the employ of PGI or ASM or which is the subject of any plan
or initiative of PGI or ASM in development or under consideration by ASM or PGI
during the time that the respective individual Stockholder is in the employ of
PGI or ASM and that the individual Stockholder was aware of or involved in.  For
purposes of this Agreement, John Inglis' current separate business operations,
if any, set specifically forth in Schedule 4.9 of the Disclosure Schedule shall
                                  ------------                                 
not constitute activities that are deemed to be in Competition with ASM.

          "Directly or Indirectly" means as an individual, partner, shareholder,
director, officer, member, principal, agent or employee.

          "Person" means an individual, corporation, partnership, joint venture,
limited liability company, trust or other entity.

                    "Restricted Territory" means anywhere in the entire world.

          (b) Stockholders shall not, for a period of   *  years after the
Closing Date, Directly or Indirectly, engage in any Competition in the
Restricted Territory; provided, however, that the Stockholders may, without
violating this covenant:  (i) own as a passive investment not in excess of 5% of
the outstanding capital stock of a corporation which engages in Competition if
such capital stock is a security which is actively traded on an established
national securities exchange; (ii) have an ownership interest otherwise
proscribed by this Section 4.9 if such interest arises as a result of the
acquisition of a business entity not principally engaged in Competition; and
(iii) John Inglis, Kearney and Dethlefs may perform their obligations to ASM
under the Inglis Employment Agreement, the Kearney Employment Agreement, and the
Dethlefs Employment Agreement (each as hereinafter defined), respectively.

          (c) Stockholders acknowledge that in view of the nature of the
business and the business objectives of PGI in purchasing the Stock of ASM, and
the Purchase Consideration paid to the Stockholders therefor, the foregoing
territorial and time limitations are reasonable and properly required for the
adequate protection of PGI and ASM and that in the event that any such
territorial or time limitation is deemed to be unreasonable and is then reduced
by a court of competent jurisdiction, then, as reduced, the territorial and/or
time limitation shall be enforced.

                                      37

 
          (d) Stockholders further acknowledge that the remedy at law for any
breach by it of the agreements contained in this Section 4.9 will be inadequate
and that PGI and ASM will be entitled to seek injunctive relief without being
required to prove actual damages or post bond.  This Section 4.9 constitutes an
independent and severable covenant and if any or all of the provisions of this
Section 4.9 are held to be unenforceable for any reason whatsoever, it will not
in any way invalidate or affect the remainder of this Agreement which shall
remain in full force and effect.

     4.10  Non-Interference.
           ---------------- 

          (a) Stockholders jointly (for a long as a Stockholder is in ASM's
employ) and severally (regardless of whether in the employ of ASM) covenant and
agree that other than in connection with the performance of the Inglis
Employment Agreement, the Kearney Employment Agreement and the Dethlefs
Employment Agreement (each, as hereinafter defined), neither the Stockholders,
nor any Person directly or indirectly controlling, controlled by or under common
control with the Stockholders will, for a period of * years after the
Closing, directly or indirectly, for whatever reason, whether for their own
account or for the account of any other Person, during the period that the
covenant set forth in Section 4.9 hereof remains in effect:  (i) solicit, deal
with or otherwise interfere with PGI or ASM in connection with any aspect of the
Business or with PGI's or ASM's existing or potential contracts or relationships
with any vendor, customer, supplier, affiliate, employee, officer, director or
any independent contractor, whether the Person is employed by or associated with
the Business or with PGI or ASM on the Closing Date or at any time thereafter;
(ii) solicit, accept, deal with or otherwise interfere with the continuance of
supplies to PGI or ASM (or the terms relating to such supplies), from any
vendors, suppliers or customers who have been supplying goods, materials or
services to ASM at any time during the five years immediately preceding the date
of this Agreement; (iii) solicit, accept, deal with or otherwise interfere with
any of the existing or potential contracts or relationships with any independent
contractor, customer, vendor, supplier, client or consultant of the Business or
PGI or ASM, or any Person who is a bona fide or prospective independent
contractor, customer, client or consultant thereof; or (iv) solicit or otherwise
interfere with any existing or proposed contract between the Business of PGI or
ASM and any other party whatsoever.

     4.11  Cooperation.
           ----------- 

          Stockholders jointly (for as long as a Stockholder is in ASM's employ)
and severally (regardless of whether employed by ASM) covenant and agree both
before and after the Closing hereunder:  (a) to give full cooperation to PGI and
ASM (including, without limitation, giving written notice as requested by PGI or
ASM and referring all telephone inquiries regarding, relating to or in
connection with the Business to PGI or ASM) to assure that each supplier and
customer of ASM will continue to do business with PGI and ASM on substantially
the same terms and conditions subsequent to the Closing Date as such supplier or
customer did with ASM before such date; (b) to cooperate fully with PGI and ASM
in order to effect the transfer of, and assure PGI and ASM of the continued
benefit and full enjoyment of, the Business; and (c) to cooperate fully with PGI
in providing to PGI all information that PGI identifies pertaining to ASM that
PGI identifies as necessary to the Registration Statement for PGI's Public
Offering.  During the period 


* Confidential information has been omitted and filed separately with the 
  Commission.

                                      38

 
prior to the Closing Date, ASM agrees to consult with PGI regarding any material
changes, contracts, or personnel actions or other material events involving ASM
or the business.

     4.12  Initial Public Offering.
           ----------------------- 

          PGI will inform ASM and the Stockholders in writing of any applicable
rules, regulations or requirements applicable to ASM or the Stockholders that
are required to complete PGI's Public Offering, and ASM and the Stockholders
agree to assist PGI in complying with such rules, regulations and requirements.
ASM will participate in the development of information concerning ASM for
disclosure in connection with the offering process.  PGI will not publish any
subjective non-historical or forward-looking information concerning ASM without
ASM's prior review and written approval, and will publish only such information
as shall be necessary and required in connection with the Public Offering,
provided that such information shall be reviewed by ASM.

     4.13  Postponement of Contemplated Public Financing.
           --------------------------------------------- 

          PGI shall notify ASM within five business days of any material adverse
change in PGI's business or other circumstance that would have the effect of
canceling the anticipated Public Offering or postponing it beyond February 28,
1997.  Upon ASM's receipt of such notice, the Parties shall agree upon an
extension of the Closing Date or ASM and the Stockholders shall provide PGI
written notice that PGI shall have 30 additional days from the date of such
written notice in which to obtain alternative financing.  If PGI is able,
through the exercise of reasonable commercial efforts, to obtain alternative
financing on terms reasonably acceptable to it, then the obligations of the
Parties under this Agreement shall continue and the Closing shall occur as soon
as reasonably practicable, but in no event later than five business days
following the closing of such financing.

     4.14  Employees.
           --------- 

          PGI agrees that any individuals who are full-time employees of ASM on
the Closing Date will remain employees of ASM immediately after the Closing.
Such individuals will be referred to herein as "ASM Employees."  The employment
by ASM of ASM Employees will be "at will" and nothing herein expressed or
implied is intended to confer upon any such ASM Employee any rights or remedies
of any nature or kind whatsoever under or by reason of this Agreement,
including, without limitation, any rights to employment for a specific period.

     4.15  Other Actions.
           ------------- 

          PGI shall not take any action or fail to take any action permitted by
this Agreement with the knowledge that such action or failure to take action
would result in (i) any of the representations and warranties of PGI set forth
in this Agreement becoming untrue or (ii) any of the conditions to the Purchase
and Sale set forth in Article V not being satisfied.



                                      39

 
     4.16  Acceleration of Earn-Out.
           ------------------------ 

          (a) PGI shall pay the Stockholders the Accelerated Earn-Out Amount (as
hereinafter defined) in accordance with the terms hereof upon the occurrence of
the following (each, an "Accelerated Earn-Out Event"):

              (i) The breach, prior to the full payment to the Stockholders of
Additional Purchase Consideration due Stockholders hereunder in accordance with
the terms hereof, of any one or more obligations of PGI to the Stockholders
under this Agreement involving the payment of money, after the expiration of any
applicable opportunity to cure and/or the arbitrator's final award in favor of
Stockholders for any matter submitted to arbitration in accordance with Section
8.15 hereof (a "Final Monetary Breach"), and provided that said breach involves
a monetary sum that alone, or on combination with other Final Monetary Breaches,
exceeds $100,000 (a "Material Financial Default").

              (ii) In the event that, prior to the full payment to the
Stockholders of Additional Purchase Consideration due Stockholders hereunder in
accordance with the terms hereof, the primary lender for PGI takes any action
with respect to the Additional Purchase Consideration Account or the assets of
ASM that the Stockholders reasonably believe renders it impossible for PGI to
pay the 1997 Additional Purchase Consideration or the 1998 Additional Purchase
Consideration when due (an "Earn-Out Impossibility Event"). In the event of the
occurrence of circumstances that the Stockholders reasonably believe constitute
an Earn-Out Impossibility Event, the Stockholders shall send a written notice to
such effect to PGI stating the basis for such belief (an "Anticipated Default
Notice"). Upon receipt of an Anticipated Default Notice, PGI and the
Stockholders shall consult for a period of 30 days with respect to Stockholders'
concerns as set forth in the Anticipated Default Notice. If, following such
consultation, PGI and the Stockholders are unable to resolve the Stockholders'
concerns, then PGI shall have 60 days within which to provide reasonable
alternative security for the payment of the Additional Purchase Consideration
("Alternate Security"). In the event that PGI is unable to provide such
Alternate Security, an Accelerated Earn-Out Event shall be deemed to have
occurred.

              (iii) An Insolvency Event (as hereinafter defined) occurring prior
to the full payment to the Stockholders of Additional Purchase Consideration due
Stockholders hereunder in accordance with the terms hereof. As used herein, an
"Insolvency Event" shall mean (A) if PGI voluntarily submits itself to
bankruptcy or is involuntarily submitted to bankruptcy and the action is not
dismissed within 60 days of filing and (B) PGI's obligation to pay the
Additional Purchase Consideration as set forth herein is rejected or otherwise
terminated in connection with the bankruptcy proceeding. No Insolvency Event
shall be deemed to have occurred unless and until the rejection or other
termination of any material portion of PGI's obligation to pay Additional
Purchase Consideration shall have become final and non-appealable.

              (iv) A Change in Control (as hereinafter defined) occurring prior
to the full payment to the Stockholders of Additional Purchase Consideration due
Stockholders hereunder in accordance with the terms hereof. As used herein, a
"Change in Control" shall mean: (A) following a sale or other transfer or
disposition of all or substantially all of the assets of




                                      40

 
ASM, or a merger or consolidation of ASM, or a sale or other transfer or
disposition of the stock of ASM, PGI no longer has, directly or indirectly, a
controlling interest in ASM; or (B) there shall occur the sale or other transfer
or disposition of all or substantially all of the assets of PGI, or a merger or
consolidation of PGI following which the Chief Executive Officer and Executive
Management Team of PGI is changed as a result of or after such acquisition of
control.

          (b)  Payment Matters.
               --------------- 

              (i) As used herein, the "Accelerated Earn-Out Amount" shall mean
(A) with respect to an Accelerated Earn-Out Event occurring in calendar year
1997, the Accelerated Earn-Out Amount shall be   *    ; and (B) with respect
to an Accelerated Earn-Out Event occurring in calendar year 1998, the
Accelerated Earn-Out Amount shall be the sum of (X) the actual amount of unpaid
1997 Additional Purchase Consideration, if any, and (Y) an amount for calendar
year 1998 equal to  *  of the difference between (I) *  of PTPECNI as
reflected in the 1998 Business Plan for ASM and (II) the actual PTPECNI for
calendar year 1997.

              (ii) Either party shall have the obligation to submit any dispute
with respect to the operation of this Section 4.16, including whether an
Accelerated Earn-Out Event has occurred and the calculation of the Accelerated
Earn-Out Amount, to arbitration in accordance with Section 8.15 hereof. No
Accelerated Earn-Out Amount shall be due and payable until 30 days following a
final determination by the arbitrator in accordance with Section 8.15 hereof
that any Accelerated Earn-Out Amount is due.

     4.17  Termination of Certain Covenants.
           -------------------------------- 

          (a) John Inglis's obligations pursuant to Section 4.9 and 4.10 hereof

triggering termination of the covenants set forth in Sections 4.9 and 4.10
hereof with respect to Inglis are referred to herein as "Final Inglis Covenant
Termination Events."  John Inglis or PGI shall have the right to submit any

arbitration, the covenants set forth in Section 4.9 and 4.10 shall not terminate
until a final determination by the arbitrator in accordance with Section 8.15
hereof that a Final Inglis Covenant Termination Event has occurred and, in the
case of the Accelerated Earn-Out Events arising pursuant Section 4.16, that any
Accelerated Earn-Out Amount has not been paid when due.

          (b) Kearney's obligations pursuant to Section 4.9 and 4.10 hereof
shall terminate upon (i) the occurrence of an Accelerated Earn-Out Event, (ii)

arbitration, the covenants set forth in Section 4.9 and 4.10 shall not terminate
until a final determination by the arbitrator in accordance with Section 8.15
hereof that a Final Kearney Covenant Termination Event has occurred and, in the
case of the Accelerated Earn-Out Events arising pursuant Section 4.16, that any

obligations pursuant to Section 4.9 and 4.10 in accordance with the provisions
of Section 4.17 hereof, the covenants set forth in Sections 4.7 and 4.8 hereof

obtaining or doing business, (ii) any confidential or proprietary information

          (a) the breach of any representation or warranty by ASM or the
Stockholders contained herein or in any document delivered hereunder at the
Closing, except as covered by Section 7.2(e) hereof;

                                      47

contained herein or in any document delivered hereunder at the Closing, except
as covered by Section 7.2(e) hereof;

          (c) any liabilities of ASM of any nature, whether accrued, absolute,

the Closing Date, and which (i) were not reflected on the Most Recent Balance
Sheet, (ii) were not otherwise disclosed on the Disclosure Schedule (other than
through the disclosure of general possibilities of liabilities on certain

consummation of this transaction;

          (e) a breach of the representation set forth in Section 2.14(b)(i) and

          (f) without limitation, a breach of the representation set forth in
Section 2.14(b)(i) and (ii) with respect to letters of intent or other

Hall Arrangements") as though such 1997 Hall Arrangements had been included as
1997 Hall Contracts on Schedule 2.14.

          Notwithstanding anything in this Agreement to the contrary, ASM and
the Stockholders shall be required to update the Disclosure Schedule during the
period between the execution of this Agreement and the date 5 days prior to the
Closing Date (the "Disclosure Termination Period") if such update is necessary
to render the Disclosure Schedule complete and accurate.  No such amendment
shall alter the parties' rights and obligations under this Agreement, provided
that the maximum amount of any PGI Loss with respect to events occurring
following the date of this Agreement and disclosed to PGI prior to the
Disclosure Termination Period shall be $200,000, exclusive of any such loss

     7.3  Indemnification by PGI.
          ---------------------- 

          Except as otherwise limited by this Article VII, PGI shall indemnify,
defend and hold harmless Stockholders from and against any and all liabilities,
losses, damages, claims, costs and expenses, interest, awards, judgments and
penalties (including, without limitation, reasonable legal costs and expenses)
actually suffered or incurred by it (hereinafter a "Stockholder Loss") arising

          (c) any liabilities of ASM of any nature, whether accrued, absolute,
contingent or otherwise arising following the Closing Date and based upon the
conduct of the Business or the ownership or use of ASM property after the
Closing Date; or

          (d) As PGI is responsible for the preparation of the Registration
Statement and for the compilation of the ASM financial statements and combined
pro forma financial statements included therein, any investigation, suit,
action, claim, liability or damages suffered by ASM prior to the Closing Date,
or by the Stockholders, asserted or initiated by any person, entity, or
governmental or regulatory agency resulting from or arising in connection with
the contemplated public offering of PGI, unless such investigation, suit,
action, claim, liability or damages shall be the result of, arise out of, or be
based upon any untrue statement or alleged untrue statement of a material fact
made by ASM which PGI includes in the Registration Statement, or the omission or
alleged omission to state a material fact required to be stated in the
Registration Statement or necessary to make the statements therein not
misleading, and furnished or to be furnished to PGI by or on behalf of the
Stockholders specifically for inclusion therein.

     7.4  General Indemnification Provisions.
          ---------------------------------- 

          (a) For the purposes of this Section 7.4, the term "Indemnitee" shall
refer to the Person indemnified, or entitled, or claiming to be entitled to be
indemnified, pursuant to the provisions of Section 7.2 or 7.3, as the case may
be; the term "Indemnitor" shall refer to the Person having the obligation to
indemnify pursuant to such provisions; and "Losses" shall refer to the
"Stockholder Losses" or the "PGI Losses", as the case may be.

          (b) An Indemnitee shall give written notice (a "Notice of Claim") to
the Indemnitor within ten (10) business days after the Indemnitee has knowledge
of any claim (including a Third Party Claim, as hereinafter defined) which an
Indemnitee has determined has given or could give rise to a right of
indemnification under this Agreement.  No failure to give such Notice of Claim
shall affect the indemnification obligations of the Indemnitor hereunder, except
to the extent Indemnitor can demonstrate such failure materially prejudiced such
Indemnitor's ability to successfully defend the matter giving rise to the claim.
The Notice of Claim shall state the nature of the claim, the amount of the Loss,
if known, and the method of computation thereof, all with reasonable
particularity and containing a reference to the provisions of this Agreement in
respect of which such right of indemnification is claimed or arises.

          (c) The obligations and liabilities of an Indemnitor under this
Article VII with respect to Losses arising from claims of any third party that
are subject to the indemnification provisions provided for in this Article VII
("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions:  the Indemnitee at the time it gives a Notice
of Claim to the Indemnitor of the Third Party Claim shall advise the 

                                      49

 
Indemnitor that it shall be permitted, at its option, to assume and control the
defense of such Third Party Claim at its expense and through counsel of its
choice if it gives prompt notice of its intention to do so to the Indemnitee and
confirms that the Third Party Claim is one with respect to which the Indemnitor
is obligated to indemnify. In the event the Indemnitor exercises its right to
undertake the defense against any such Third Party Claim as provided above, the
Indemnitee shall cooperate with the Indemnitor in such defense and make
available to the Indemnitor all witnesses, pertinent records, materials and
information in its possession or under its control relating thereto as is
reasonably required by the Indemnitee. Except for the settlement of a Third
Party Claim which involves the payment of money only and for which the
Indemnitee is totally indemnified by the Indemnitor, no Third Party Claim may be
settled by the Indemnitor without the written consent of the Indemnitee, which
consent shall not be unreasonably withheld. Similarly, no Third Party Claim may
be settled by the Indemnitee without the written consent of the Indemnitor,
which consent shall not be unreasonably withheld.

          (d) Any indemnification obligations of Stockholders with respect to a
PGI Loss shall be subject to offset against amounts owed by PGI to Stockholders
hereunder, if the obligation of Stockholders shall have been reduced to the
judgment of a court of competent jurisdiction or the award of an arbitrator
under any arbitration pursuant to Section 8.15 hereof.

     7.5  Limits on Indemnification.
          ------------------------- 

          No claim may be made against ASM or Stockholders for indemnification
hereunder unless and only to the extent the aggregate of all PGI Losses (other
than Hall Contact Losses) incurred exceed $50,000 (the "Basket").  Thereafter,
indemnification shall be available for all PGI Losses commencing with the first
dollar of loss.  No claim may be made against PGI for indemnification hereunder
unless and only to the extent the aggregate of all Stockholder Losses incurred
exceeds the Basket.  Notwithstanding anything to the contrary set forth herein,
no claim may be made against the Stockholders with respect to a Hall Contract
Loss (other than with respect to 1997 Hall Arrangements) except to the extent of
the $250,000.  PGI and the Stockholders shall be entitled to immediate
reimbursement of any PGI Losses or Stockholder losses hereunder with respect to
which there is no dispute concerning the other party's obligation to indemnify
such loss.  With respect to any PGI Losses or Stockholder losses with respect to
which there is a dispute concerning the other party's obligation to indemnify,
such dispute shall be submitted to expedited arbitration pursuant to Section
8.15 hereof.  As set forth in Section 1.5(c)(v)(D) above, PGI shall be entitled
to withdraw the full amount, up to an aggregate of $250,000, of any Hall
Contract Loss from the Additional Purchase Consideration Account if the
Stockholders do not pay the full amount of any Hall Contract Loss to PGI within
30 days following notice of such Hall Contract Loss from PGI or, if contested by
the Stockholders, after the final decision of the arbitrator under (S) 8.15.

     7.6  Adjustment of Liability.
          ----------------------- 

          Any indemnifiable Stockholder Loss or PGI Loss, as the case may be,
shall be reduced by any tax benefit accruing to the indemnified party on account
of the indemnification payment and by the amounts actually recovered by the
indemnified party from its insurance carriers and any amounts recovered by such
party subsequent to the payment by the indemnifying 



                                      50

 
party hereunder with respect to the same claim shall be remitted to such
indemnifying party, except that such remittance shall not exceed the amount of
the indemnification payment made by such indemnifying party.

     7.7  Indemnification as Exclusive Remedy From and After Closing.
          ---------------------------------------------------------- 

          From and after the Closing, neither party hereto shall be liable or
responsible in any manner whatsoever to the other party, whether for
indemnification or otherwise, except for indemnity as expressly provided in this
Article VII which provides the exclusive remedy and cause of action of the
parties hereto with respect to any matter arising out of or in connection with
this Agreement, except for (i) any breaches of Sections 4.6, 4.7, 4.8, 4.9,
4.10, and 4.11 of this Agreement, or (ii) PGI's obligation to pay Additional
Purchase Consideration pursuant to Section 1.5(c) and 1.5(d) hereof.

     7.8  Waiver of Contribution.
          ---------------------- 

          Stockholders hereby waive any right of contribution or similar remedy
against ASM following the Closing.

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

          No Party shall issue any press release or public disclosure relating
to the subject matter of this Agreement without the prior written approval of
the other Parties; provided, however, that any Party may make any public
disclosure it believes in good faith is required by law or regulation (in which
case the disclosing Party shall advise the other Parties and provide them with a
copy of the proposed disclosure prior to making the disclosure).
Notwithstanding the foregoing, PGI shall have the right to make disclosure with
respect to ASM and the transaction set forth herein in its registration
statement as required by applicable law.

     8.2  No Third Party Beneficiaries.
          ---------------------------- 

          This Agreement shall not confer any rights or remedies upon any person
other than the Parties and their respective successors and permitted assigns.

     8.3  Entire Agreement.
          ---------------- 

          This Agreement (including the documents referred to herein)

understandings, agreements, or representations by or among the Parties, written
or oral, with respect to the subject matter hereof, including without limitation
any and all prior employment or similar agreements between ASM and any
Stockholder and any amendment or supplement thereto.

Parties named herein and their respective successors and permitted assigns.  No
Party may assign either this Agreement or any of its rights, interests, or
obligations hereunder without the prior written approval of the other Parties;

4.16, 4.17(a), 4.17(b), 7.4(d) or 7.5 of this Agreement (a "Dispute"), either
party in such dispute shall have the right or the obligation (subject to the
terms of the section under which the Dispute has arisen) to submit such Dispute
to expedited binding arbitration as set forth herein.  The party seeking
arbitration (the "Moving Party") shall provide a written request for arbitration
(the "Arbitration Request") to the other party (the "Respondent Party").  The
Arbitration Request shall set forth in detail the Moving Party's position and
arguments concerning the Dispute and shall state clearly 

                                      55

 
the desired relief under this Agreement. Following the receipt of such request,
the Moving Party and the Respondent Party shall negotiate in good faith for a
period of 15 days in an attempt to resolve such dispute. If the Moving Party and
the Respondent Party are unable to resolve such Dispute, the Moving Party shall
have the right to provide a written request for arbitration to the American
Arbitration Association and shall simultaneously provide a copy of such
Arbitration Request to the Respondent Party. Within five days of its receipt of
the Arbitration Request, the American Arbitration Association shall appoint a
single arbitrator (the "Arbitrator") to adjudicate the Dispute. Immediately upon
the Respondent Party's receipt of the Arbitration Request, and continuing for 30
days thereafter, the Moving Party and the Respondent Party shall cooperate and
share information with each other in order to discover all facts relevant to the
Dispute ("Discovery"). The Arbitrator shall have authority to adjudicate and
issue orders with respect to any disagreements or disputes arising in connection
with such Discovery. Within 30 days after the conclusion of Discovery, the
Respondent Party shall file with the Arbitrator and the Moving Party its
response (the "Arbitration Response") to the Arbitration Request, which
Arbitration Response shall set forth in detail the Respondent Party's position
and arguments concerning the Dispute. Within the same 30-day period, the Moving
Party shall be entitled to amend and supplement its Arbitration Request based
upon information arising from the Discovery. Within five days after the
Respondent Party's filing of the Arbitration Response, the Arbitrator shall set
a date for a hearing (the "Hearing"), which date shall be within 30 days. At the
Hearing, the Moving Party and the Respondent Party shall each present their
positions and arguments with respect to the Dispute subject to such reasonable
hearing rules as shall be set by the Arbitrator, provided that the Hearing shall
last no longer than two days. Within 30 days after the Hearing, the Arbitrator
shall issue a written decision (the "Decision") with respect to the Dispute,
which Decision shall take into account all information and arguments set forth
in the Arbitration Request, the Arbitration Response, and presented at the
Hearing, and which Decision shall be final and binding among the Parties with
respect to the subject matter of the Dispute.

                                      56
