              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.       The accompanying unaudited condensed consolidated financial statements
         have been prepared in accordance with generally accepted accounting
         principles for interim financial information and with the instructions
         to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not
         include all of the information and footnotes required by generally
         accepted accounting principles for complete financial statements. In
         the opinion of management, all adjustments (consisting of normal
         recurring accruals) considered necessary for a fair presentation for
         the interim periods presented have been included. Operating results for
         the three and six month periods ended February 29, 1996 are not
         necessarily indicative of the results that may be expected for the year
         ending August 31, 1996. For further information, refer to the
         consolidated financial statements and footnotes thereto included in
         PENWEST's annual report on Form 10-K for the fiscal year ended August
         31, 1995.


2.       DEBT

         On December 22, 1995, the Company completed an unsecured $35 million
         credit agreement with four banks expiring on December 30, 1998 under   
         which there were $15.3 million outstanding at quarter end. Borrowing
         rates available to the Company under the agreement are based on prime
         rate or the interbank offered rate depending on the selection of
         borrowing options. The agreement replaced an unsecured term agreement
         which at December 22, 1995, had $15.3 million of borrowings
         outstanding and an unsecured $15 million revolving line of credit
         under which there were no outstanding borrowings at December 22, 1995.

         The new debt agreement contains, among other terms, certain
         restrictions related to limitations on indebtedness and minimum net
         worth, which are similar to restrictions on previously existing debt.
         In addition, the Company is required to maintain a minimum fixed charge
         coverage ratio.

3.       INCOME TAXES

         The effective tax rate for the six-month period ended February 29, 1996
         was 31% compared to the statutory rate of 34%. The effective rate was
         lower than the statutory rate due to state tax refunds received by the
         Company.

4.       SALE OF COGENERATION ASSETS

         During the second quarter of fiscal year 1995, the Company completed a
         sale of the turbine and the boilers constituting the assets of its
         cogeneration facility in Vancouver, Washington. A pretax gain on the
         sale of $899,000 was recorded in such second quarter and is shown as
         other income.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Liquidity

PENWEST maintains a highly liquid position. Liquidity at February 29, 1996
consisted of the following: cash and cash equivalents of $2.1 million, working
capital of approximately $30.0 million, and several uncommitted lines of credit 
with various banks aggregating $15 million that may be used for overnight
borrowings under which there were no borrowings outstanding. On December 22,
1995, the Company completed a new $35 million credit agreement with four banks,
replacing both an unsecured term agreement which had $15.3 million outstanding
and a $15 million revolving credit agreement under which there were no
borrowings outstanding at December 22, 1995.

Cash flow from operations for the six months ended February 29, 1996 was $8.6
million compared to $15.3 million in the corresponding period a year ago. The
decrease is primarily due to increases in receivables and inventories, and lower
profitability. The Company used operating cash flow and short-term borrowings to
finance capital expenditures during the first six months of the year.

The Board of Directors declared a $0.05 per share dividend which was paid on
March 1, 1996, to shareholders of record as of February 16, 1996.

Capital Resources

Additions to property, plant and equipment during the six months ended February
29, 1996 were $8.1 million. Second quarter additions of $5.3 million were
directed primarily to ongoing operating enhancements at Penford Products Co. in
Cedar Rapids, Iowa.

Results of Operations

Net income was $908,000, or $0.13 per share, for the second quarter compared to
net income of $2.2 million, or $0.31 per share, for the corresponding period a
year ago. The prior year period included a non-recurring gain of $899,000, or
$593,000 on an after tax basis, from the sale of the assets of Pacific
Cogeneration Inc. Net income for the six months was $2.7 million, or $0.38 per
share, compared with $3.9 million, or $0.55 per share, in the year earlier
period.

Sales increased in the second quarter and the first six months of fiscal year
1996 to $46.3 million and $91.9 million, respectively, representing a 9.2% and
7.9% increase, respectively, from the corresponding periods a year ago. Most of
the second quarter increase is due to acutely higher corn costs, a key component
used in pricing Penford's paper chemical products, which are generally passed
through to customers. Sales volumes at Penford were down from a year ago
primarily due to a sharp drop in production by the paper industry. Lower
production in the paper industry led to reduced shipments to existing customers
during the quarter and delayed shipments of new business. Even with sharp
reductions in output by the paper industry, our customers' finished goods
inventory levels remain high because of soft end-user demand for paper. Penwest
Pharmaceuticals Group experienced continued volume growth and posted record
revenues for the quarter. Although shipments were down

                                       7
<PAGE>   8
from the first quarter resulting from seasonal downtime, Penwest Foods' revenues
increased over the same period a year ago primarily due to higher volumes of its
line of starch-based coatings for french fries.

The gross margin for the three-month period ended February 29, 1996 was 24.0%
compared to 28.1% in the corresponding period a year ago. Lower volumes of
Penford's high end starches and the negative effect of a rapidly rising corn
market contributing approximately the same gross margin dollars on higher sales
dollars resulted in a lower gross margin percentage.

Operating expenses in the second quarter rose $150,000, or 1.8%. For the year
operating expenses are up 7.5% which is primarily due to increased investment in
research and development especially in the Penwest Pharmaceuticals Group.

Net interest expense for the second quarter of fiscal year 1996 was $1.3 million
compared to $1.1 million for the corresponding period a year ago. The increase
reflects lower capitalized interest and lower investment income throughout the
current quarter.

Forward-looking Statements

Penford's net corn costs have continued to rise subsequent to the end of the
second quarter and are expected to negatively impact gross margins on fixed
sales contracts in the foreseeable future. Price increases for byproduct sales,
which are netted against the cost of corn, have not kept up with the increases
in corn cost. Conditions in the corn market are such that the changes in the
value of the Company's futures contracts have not completely offset rising net
corn costs on its fixed price contracts. These are unusual market conditions and
the Company continues to pursue ways to better protect its margins on fixed
sales contracts.

If the paper industry rebounds later this calendar year, stronger starch sales
volume could result from the resumption of alkaline-based conversions, and from
a rebound in demand stimulated by reductions in our customers' inventories and
recent lower paper prices. Gross margin percentages are also anticipated to
improve if the paper industry strengthens and corn costs recede from historical
highs.

The above discussion contains forward-looking statements. There are certain
important factors that could cause results to differ materially from those
anticipated by the statements made above. These factors include, but are not
limited to, the market price of corn and corn byproducts, the economic condition
of the paper industry, and competition. Additional information on these and
other factors which could affect the Company's financial results is included in
the Company's 1995 Annual Report to Shareholders, its Form 10-K for the fiscal
year ended August 31, 1995, and its Form 10-Q for the fiscal quarter ended
November 30, 1995, on file with the Securities and Exchange Commission.

         2.03     Procedure for Borrowing.

                  (a) Each Borrowing shall be made on a Business Day upon a
Company's irrevocable written notice delivered to the Agent in the form of a
Notice of Borrowing, which notice must be received by the Agent prior to (i)
10:00 a.m. San Francisco, California time, three Business Days prior to the
requested Borrowing Date, in the case of Offshore Rate Loans; and (ii) 9:00 a.m.
on the requested Borrowing Date, in the case of Base Rate Loans, specifying:

                  (1) the amount of the Borrowing, which shall be in an
         aggregate minimum amount (y) of $2,000,000 or any integral multiple of
         $500,000 in excess thereof in the case of Offshore Rate Loans or (z)
         which is an integral multiple of $500,000 in the case of Base Rate
         Loans;

                  (2) the requested Borrowing Date, which shall be a Business
         Day;

                  (3) the Type of Loans comprising the Borrowing; and

                                       18
<PAGE>   25
                  (4) the duration of the Interest Period applicable to such
         Loans included in such notice. If the Notice of Borrowing fails to
         specify the duration of the Interest Period for any Borrowing comprised
         of Offshore Rate Loans, such Interest Period shall be three months;

provided, however, that with respect to the Borrowing to be made on the Closing
Date, the Notice of Borrowing shall be delivered to the Agent not later than
10:00 a.m. San Francisco, California time) one Business Day before the Closing
Date and such Borrowing will consist of Base Rate Loans only.

                  (b) The Agent will promptly notify each Bank of its receipt of
any Notice of Borrowing and of the amount of such Bank's Pro Rata Share of that
Borrowing.

                  (c) Each Bank will make the amount of its Pro Rata Share of
each Borrowing available to the Agent for the account of the borrowing Company
at the Agent's Payment Office by 12:00 noon San Francisco, California time) on
the Borrowing Date requested by the such Company in funds immediately available
to the Agent. The proceeds of all such Loans will then be made available to the
borrowing Company by the Agent at such office by crediting the account of such
Company on the books of BofA with the aggregate of the amounts made available to
the Agent by the Banks and in like funds as received by the Agent.

                  (d) After giving effect to any Borrowing, unless the Agent
shall otherwise consent, there may not be more than five different Interest
Periods in effect.

         2.04     Conversion and Continuation Elections.

                  (a) A Company may, upon irrevocable written notice to the
Agent in accordance with subsection 2.04(b):

                      (1) elect, as of any Business Day, in the case of its Base
         Rate Loans, or as of the last day of the applicable Interest Period, in
         the case of Offshore Rate Loans, to convert any Base Rate Loans or any
         part thereof in an amount not less than $2,000,000 or that is an
         integral multiple of $500,000 in excess thereof into Offshore Rate
         Loans or to convert any Offshore Rate Loans or any part thereof in
         integral multiples of $500,000 into Base Rate Loans; or

                      (2) elect, as of the last day of the applicable Interest
         Period, to continue any of its Offshore Rate Loans having Interest
         Periods expiring on such day (or any part thereof in an amount not less
         than $2,000,000 or that is in an integral multiple of $500,000 in
         excess thereof);

provided, that if at any time the aggregate amount of Offshore Rate Loans in
respect of any Borrowing to a Company is reduced, by payment, prepayment, or
conversion of part thereof to be less

                                       19
<PAGE>   26
than $2,000,000, such Offshore Rate Loans shall automatically convert into Base
Rate Loans, and on and after such date the right of such Company to continue
such Loans as, and convert such Loans into, Offshore Rate Loans shall terminate.

                  (b) A Company shall deliver a Notice of
Conversion/Continuation to be received by the Agent not later than (i) 10:00
a.m. San Francisco, California time at least three Business Days in advance of
the Conversion/Continuation Date, if its Loans are to be converted into or
continued as Offshore Rate Loans; and (ii) 9:00 a.m. San Francisco, California
time on the Business Day of the Conversion/Continuation Date, if the Loans are
to be converted into Base Rate Loans, specifying:

                      (1) the proposed Conversion/Continuation Date;

                      (2) the aggregate amount of Loans to be converted or
         continued;

                      (3) the Type of Loans resulting from the proposed
         conversion or continuation; and

                      (4) other than in the case of conversions into Base Rate
         Loans, the duration of the requested Interest Period.

                  (c) If upon the expiration of any Interest Period applicable
to its Offshore Rate Loans, a Company has failed to select timely a new Interest
Period to be applicable to such Offshore Rate Loans or if any Default or Event
of Default then exists, a Company shall be deemed to have elected to convert its
Offshore Rate Loans into Base Rate Loans effective as of the expiration date of
such Interest Period.

                  (d) The Agent will promptly notify each Bank of its receipt of
a Notice of Conversion/Continuation, or, if no timely notice is provided by the
borrower Company, the Agent will promptly notify each Bank of the details of any
automatic conversion. All conversions and continuations shall be made ratably
according to the respective outstanding principal amounts of the Loans with
respect to which the notice was given held by each Bank.

                  (e) Unless the Majority Banks otherwise consent, during the
existence of a Default or Event of Default, a Company may not elect to have a
Loan converted into or continued as an Offshore Rate Loan.

                  (f) After giving effect to any conversion or continuation of
Loans, unless the Agent shall otherwise consent, there may not be more than five
different Interest Periods in effect.

         2.05     Voluntary Termination or Reduction of Commitments.

                                       20
<PAGE>   27
Penwest may, upon not less than five Business Days' prior notice to the Agent,
terminate the Commitments, or permanently reduce the Commitments by integral
multiples of $1,000,000; unless, after giving effect thereto and to any
prepayments of Loans made on the effective date thereof, the then outstanding
principal amount of the Loans would exceed the amount of the combined
Commitments then in effect. Once reduced in accordance with this Section, the
Commitments may not be increased. Any reduction of the Commitments shall be
applied to each Bank according to its Pro Rata Share. All accrued commitment
fees to, but not including the effective date of any reduction or termination of
Commitments, shall be paid on the effective date of such reduction or
termination.

         2.06     Optional Prepayments. Subject to Section 3.04, a Company may,
at any time or from time to time, upon not less than three Business Days
irrevocable notice to the Agent with respect to Offshore Rate Loans made to it
and one Business Day irrevocable written notice to the Agent with respect to
Base Rate Loans made to it, ratably prepay Loans in whole or in part, in minimum
amounts of (y) $2,000,000 or any integral multiple of $500,000 in excess thereof
with respect to Offshore Rate Loans, and (z) $500,000 or any integral multiple
of $100,000 in excess thereof with respect to Base Rate Loans. Such notice of
prepayment shall specify the date and amount of such prepayment and the Loan to
be prepaid. The Agent will promptly notify each Bank of its receipt of any such
notice, and of such Bank's Pro Rata Share of such prepayment. If such notice is
given by a Company, such Company shall make such prepayment and the payment
amount specified in such notice shall be due and payable on the date specified
therein, together with accrued interest to each such date on the amount prepaid
and any amounts required pursuant to Section 3.04.

         2.07     Repayment. The Companies shall repay to the Banks on the
Termination Date the aggregate principal amount of Loans outstanding on such
date.

         2.08     Interest.

                  (a) Each Loan shall bear interest on the outstanding principal
amount thereof from the applicable Borrowing Date at a rate per annum equal to
the Offshore Rate for the relevant Interest Period or the Base Rate, as the case
may be (and subject to the borrowing Company's right to convert to other Types
of Loans under Section 2.04), plus the Applicable Margin.

                  (b) Interest on each Loan shall be paid in arrears on each
Interest Payment Date. Interest shall also be paid on the date of any prepayment
of Loans under Section 2.06 for the portion of the Loans so prepaid and upon
payment (including prepayment) in full thereof and, during the existence of any
Event of Default, interest shall be paid on demand of the Agent at the request
or with the consent of the Majority Banks.

                                       21
<PAGE>   28
                  (c) Notwithstanding subsection (a) of this Section, while any
Event of Default exists or after acceleration, the Companies shall pay interest
(after as well as before entry of judgment thereon to the extent permitted by
law) on the principal amount of all outstanding Obligations, at a rate per annum
which is determined by adding 3% per annum to the Applicable Margin then in
effect for such Loans and, in the case of Obligations not subject to an
Applicable Margin, at a rate per annum equal to the Base Rate plus 3%; provided,
however, that, on and after the expiration of any Interest Period applicable to
any Offshore Rate Loan outstanding on the date of occurrence of such Event of
Default or acceleration, the principal amount of such Loan shall, during the
continuation of such Event of Default or after acceleration, bear interest at a
rate per annum equal to the Base Rate plus 3%.

                  (d) Anything herein to the contrary notwithstanding, the
obligations of the Companies to any Bank hereunder shall be subject to the
limitation that payments of interest shall not be required for any period for
which interest is computed hereunder, to the extent (but only to the extent)
that contracting for or receiving such payment by such Bank would be contrary to
the provisions of any law applicable to such Bank limiting the highest rate of
interest that may be lawfully contracted for, charged or received by such Bank,
and in such event the Companies shall pay such Bank interest at the highest rate
permitted by applicable law.

         2.09     Fees.

                  (a) Agency Fees. The Companies shall pay an agency fee to the
Agent for the Agent's own account, as required by the letter agreement ("Fee
Letter") between Penwest and the Arranger and Agent dated August 11, 1995.

                  (b) Commitment Fees. The Companies shall pay to the Agent for
the account of each Bank a commitment fee on the average daily unused portion of
such Bank's Commitment, computed on a quarterly basis in arrears on the last
Business Day of each calendar quarter based upon the daily utilization for that
quarter as calculated by the Agent at a rate equal to 0.25% per annum. Such
commitment fee shall accrue from the Closing Date to the Termination Date and
shall be due and payable quarterly in arrears on the last Business Day of each
calendar quarter commencing on December 29, 1995, with the final payment to be
made on the Termination Date; provided that, in connection with any reduction or
termination of Commitments under Section 2.05, the accrued commitment fee
calculated for the period ending on such date shall also be paid on the date of
such reduction or termination, with the following quarterly payment being
calculated on the basis of the period from such reduction or termination date to
such quarterly payment date. The commitment fees provided in this subsection
shall accrue at all times after the above-mentioned commencement date, including
at any time

                                       22
<PAGE>   29
during which one or more conditions in Article IV are not met.

         2.10     Computation of Fees and Interest.

                  (a) All computations of interest for Base Rate Loans when the
Base Rate is determined by BofA's "reference rate" shall be made on the basis of
a year of 365 or 366 days, as the case may be, and actual days elapsed. All
other computations of fees and interest shall be made on the basis of a 360-day
year and actual days elapsed (which results in more interest being paid than if
computed on the basis of a 365-day year). Interest and fees shall accrue during
each period during which interest or such fees are computed from the first day
thereof to the last day thereof.

                  (b) Each determination of an interest rate by the Agent shall
be conclusive and binding on the Companies and the Banks in the absence of
manifest error.

         2.11     Payments by the Companies.

                  (a) All payments to be made by the Companies shall be made
without set-off, recoupment or counterclaim. Except as otherwise expressly
provided herein, all payments by the Companies shall be made to the Agent for
the account of the Banks at the Agent's Payment Office, and shall be made in
dollars and in immediately available funds, no later than 10:00 a.m. San
Francisco, California time) on the date specified herein. The Agent will
promptly distribute to each Bank its Pro Rata Share (or other applicable share
as expressly provided herein) of such payment in like funds as received. Any
payment received by the Agent later than 10:00 a.m. (San Francisco, California
time) shall be deemed to have been received on the following Business Day and
any applicable interest or fee shall continue to accrue.

                  (b) Subject to the provisions set forth in the definition of
"Interest Period" herein, whenever any payment is due on a day other than a
Business Day, such payment shall be made on the following Business Day, and such
extension of time shall in such case be included in the computation of interest
or fees, as the case may be.

                  (c) Unless the Agent receives notice from Penwest prior to the
date on which any payment is due from any of the Companies to the Banks that
such payment in full will not be made as and when required, the Agent may assume
that such payment in full has been made to the Agent on such date in immediately
available funds and the Agent may (but shall not be so required), in reliance
upon such assumption, distribute to each Bank on such due date an amount equal
to the amount then due such Bank. If and to the extent such payment in full has
not been made to the Agent by a Company or the Companies, each Bank shall repay
to the Agent on demand such amount distributed to such Bank, together with
interest thereon at the Federal Funds Rate for each day from

                                       23
<PAGE>   30
the date such amount is distributed to such Bank until the date repaid.

         2.12     Payments by the Banks to the Agent.

                  (a) Unless the Agent receives notice from a Bank on or prior
to the Closing Date or, with respect to any Borrowing after the Closing Date, at
least one Business Day prior to the date of such Borrowing, that such Bank will
not make available as and when required hereunder to the Agent for the account
of any Company the amount of that Bank's Pro Rata Share of the Borrowing, the
Agent may assume that each Bank has made such amount available to the Agent in
immediately available funds on the Borrowing Date and the Agent may (but shall
not be so required), in reliance upon such assumption, make available to the
borrowing Company on such date a corresponding amount. If and to the extent any
Bank shall not have made its full amount available to the Agent in immediately
available funds and the Agent in such circumstances has made available to the
borrowing Company such amount, that Bank shall on the Business Day following
such Borrowing Date make such amount available to the Agent, together with
interest at the Federal Funds Rate for each day during such period. A notice of
the Agent submitted to any Bank with respect to amounts owing under this
subsection (a) shall be conclusive, absent manifest error. If such amount is so
made available, such payment to the Agent shall constitute such Bank's Loan on
the date of Borrowing for all purposes of this Agreement. If such amount is not
made available to the Agent on the Business Day following the Borrowing Date,
the Agent will notify the Company or Companies receiving such amount of such
failure to fund and, upon demand by the Agent, the Companies shall pay such
amount to the Agent for the Agent's account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal to
the interest rate applicable at the time to the Loans comprising such Borrowing.

                  (b) The failure of any Bank to make any Loan on any Borrowing
Date shall not relieve any other Bank of any obligation hereunder to make a Loan
on such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.

         2.13     Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from the

                                       24
<PAGE>   31
purchasing Bank, such purchase shall to that extent be rescinded and each other
Bank shall repay to the purchasing Bank the purchase price paid therefor,
together with an amount equal to such paying Bank's ratable share (according to
the proportion of (i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered. The Companies agree that any Bank so purchasing a
participation from another Bank may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 10.10) with respect to such participation as fully as if such Bank
were the direct creditor of the Companies in the amount of such participation.
The Agent will keep records (which shall be conclusive and binding in the
absence of manifest error) of participations purchased under this Section and
will in each case notify the Banks following any such purchases or repayments.

         2.14     Extension of Termination Date.

                  (a) Unless the Banks' commitments to lend under this Agreement
shall have sooner terminated pursuant to the terms of this Agreement, upon
written request from the Companies (an "Extension Request"), received by the
Agent not more than 60 days and not less than 30 days prior to the date that is
two years before the Termination Date then in effect, the Companies may request
that the Termination Date be extended to the date that is one year after the
current Termination Date.

                  (b) Each Bank shall use reasonable commercial efforts to
notify the Agent and the Companies by facsimile, telegram, telex or otherwise in
writing within 20 days after receipt of an Extension Request as to whether it
consents to the extension requested. If a Bank has not replied by facsimile,
telegram, telex or otherwise in writing to the Agent and to the Companies by the
end of such 20 day period, that Bank shall be deemed not to have consented to
the requested extension. The Agent shall promptly notify each Bank and the
Companies of any Bank's decision to reject the proposed extension.

                  (c) The Termination Date shall be extended pursuant to an
Extension Request if all of the Banks agree to such Extension Request.

                                   ARTICLE III

TAXES, YIELD PROTECTION, ILLEGALITY, JOINT AND SEVERAL LIABILITY

         3.01     Taxes.

                  (a) Any and all payments by any Company to each Bank or the
Agent under this Agreement and any other Loan Document shall be made free and
clear of, and without deduction or

                                       25
<PAGE>   32
withholding for, any Taxes.  In addition, the Companies shall pay all Other 
Taxes.

                  (b) If any Company shall be required by law to deduct or
withhold any Taxes, Other Taxes or Further Taxes from or in respect of any sum
payable hereunder to any Bank or the Agent, then:

                      (i)     the sum payable shall be increased as necessary so
         that, after making all required deductions and withholdings (including
         deductions and withholdings applicable to additional sums payable under
         this Section), such Bank or the Agent, as the case may be, receives and
         retains an amount equal to the sum it would have received and retained
         had no such deductions or withholdings been made;

                      (ii)    such Company shall make such deductions and
         withholdings;

                      (iii)   the Companies shall pay the full amount deducted 
         or withheld to the relevant taxing authority or other authority in
         accordance with applicable law; and

                      (iv)    the Companies shall also pay to each Bank or the
         Agent for the account of such Bank, at the time interest is paid,
         Further Taxes in the amount that the respective Bank specifies as
         necessary to preserve the after-tax yield the Bank would have received
         if such Taxes, Other Taxes or Further Taxes had not been imposed.

                  (c) The Companies agree to indemnify and hold harmless each
Bank and the Agent for the full amount of i) Taxes, ii) Other Taxes, and iii)
Further Taxes in the amount that the respective Bank specifies as necessary to
preserve the after-tax yield the Bank would have received if such Taxes, Other
Taxes or Further Taxes had not been imposed, and any liability (including
penalties, interest, additions to tax and expenses) arising therefrom or with
respect thereto, whether or not such Taxes, Other Taxes or Further Taxes were
correctly or legally asserted. Payment under this indemnification shall be made
within 30 days after the date the Bank or the Agent makes written demand
therefor.

                  (d) Within 30 days after the date of any payment by any
Company of Taxes, Other Taxes or Further Taxes, the Companies shall furnish to
each Bank or the Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to such Bank or the
Agent.

                  (e) If the Companies are required to pay any amount to any
Bank or the Agent pursuant to subsection (b) or (c) of this Section, then such
Bank shall use reasonable efforts (consistent with legal and regulatory
restrictions) to change the

                                       26
<PAGE>   33
jurisdiction of its Lending Office so as to eliminate any such additional
payment by the Companies which may thereafter accrue, if such change in the sole
judgment of such Bank is not otherwise disadvantageous to such Bank.

                  (f) If any claim shall be made against the Agent or any Bank
(for purposes of this subsection, the "Indemnitee") or if any proceeding shall
be commenced against the Indemnitee (including a written notice of such
proceeding) for any Taxes, Other Taxes, or Further Taxes as to which the
Companies are required to pay pursuant to this Section, the Indemnitee shall
promptly, upon receiving notice thereof, notify the Companies in writing of such
claim; provided that, without prejudice to any rights the Companies may have in
connection therewith, including any claim for damages for failure to give such
notice, the failure to provide such notice shall not release the Companies from
any of its obligations hereunder. If reasonably requested by the Companies in
writing within 30 days from receipt of such notice from the Indemnitee (or such
shorter period as the Indemnitee has notified the Companies is required by law
or regulation for the Companies to commence such contest), and upon
determination by the Indemnitee that the action to be taken will not result in
criminal liability, or any substantial risk of the sale, forfeiture, or loss of,
or the filing of a Lien on any asset of the Indemnitee, the Indemnitee shall
upon receipt of indemnity satisfactory to it and at the expense of the Companies
(including, without limitation, all reasonable out-of-pocket expenses, Attorney
Costs, reasonable accounting and investigatory fees and disbursements), and
provided that the Companies shall have delivered to the Indemnitee a written
acknowledgement of their indemnification obligations hereunder in respect of
such contest, in good faith contest the validity, applicability or amount of
such Taxes, Other Taxes, or Further Taxes by, in such Indemnitee's sole
discretion, (i) resisting payment thereof, (ii) not paying the same except under
protest, if protest is necessary and proper, or (iii) if payment is made, using
reasonable efforts to obtain a refund thereof in appropriate administrative and
judicial proceedings. Any contest required pursuant to the next preceding
sentence shall, at the option of such Indemnitee, be conducted by such
Indemnitee or the Companies in the name of Companies or such Indemnitee. If any
such contest involves payment of the Tax in question, the Companies shall either
make such payment directly to the appropriate authority or furnish to such
Indemnitee, at no net after-tax cost, sufficient funds to make such payment. No
Indemnitee shall settle, compromise, or close such a contest without first
giving the Companies at least 30 days prior written notice of its intent to do
so.

         3.02     Illegality.

                  (a) If any Bank determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other

                                       27
<PAGE>   34
Governmental Authority has asserted that it is unlawful, for any Bank or its
applicable Lending Office to make Offshore Rate Loans, then, on notice thereof
by the Bank to the Companies through the Agent, any obligation of that Bank to
make Offshore Rate Loans shall be suspended until the Bank notifies the Agent
and the Companies that the circumstances giving rise to such determination no
longer exist.

                  (b) If a Bank determines that it is unlawful to maintain any
Offshore Rate Loan, the Companies shall, upon its receipt of notice of such fact
and demand from such Bank (with a copy to the Agent), prepay in full such
Offshore Rate Loans of that Bank then outstanding, together with interest
accrued thereon and amounts required under Section 3.04, either on the last day
of the Interest Period thereof, if the Bank may lawfully continue to maintain
such Offshore Rate Loans to such day, or immediately, if the Bank may not
lawfully continue to maintain such Offshore Rate Loan. If the Companies are
required to so prepay any Offshore Rate Loan, then concurrently with such
prepayment, the borrower Company(ies) shall borrow from the affected Bank, in
the amount of such repayment, a Base Rate Loan.

         3.03     Increased Costs and Reduction of Return.

                  (a) If any Bank determines that, due to either:

                      (i)     the introduction of or any change after the date 
         of this Agreement (other than any change by way of imposition of or
         increase in reserve requirements included in the calculation of the
         Offshore Rate) in, or in the interpretation or administration of, any
         law or regulation; or

                      (ii)    the compliance by that Bank with any guideline or
         request from any central bank or other Governmental Authority (whether
         or not having the force of law), but only if and to the extent that
         such compliance is required or requested by the introduction of or any
         change (after the date of this Agreement) in or in the interpretation
         or administration of any guideline or request;

there shall be any increase in the cost to such Bank of agreeing to make or
making, funding or maintaining any Offshore Rate Loans, then the Companies shall
be liable for, and shall from time to time, upon demand (with a copy of such
demand to be sent to the Agent), pay to the Agent for the account of such Bank,
additional amounts as are sufficient to compensate such Bank for such increased
costs.

                  (b) If any Bank shall have determined that compliance by the
Bank (or its Lending Office) or any corporation controlling the Bank with (i)
any Capital Adequacy Regulation introduced after the date of this Agreement,
(ii) any change in any Capital Adequacy Regulation, or (iii) any change in the
interpretation or administration of any Capital Adequacy Regulation by any
central bank or other Governmental Authority

                                       28
<PAGE>   35
charged with the interpretation or administration thereof affects or would
affect the amount of capital required or expected to be maintained by the Bank
or any corporation controlling the Bank and (taking into consideration such
Bank's or such corporation's policies with respect to capital adequacy)
determines that such Bank's rate of return on capital is decreased as a
consequence of its Commitment, loans, credits or obligations under this
Agreement to a level below that which would otherwise have been achieved, then,
upon demand of such Bank to the Companies through the Agent, the Companies shall
pay to the Bank, from time to time as specified by the Bank, additional amounts
sufficient to compensate the Bank for such decrease.

         3.04     Funding Losses. The Companies shall reimburse each Bank and 
hold each Bank harmless from any loss or expense which the Bank may sustain or
incur as a consequence of:

                  (a) the failure of the Companies to make on a timely basis any
payment of principal of any Offshore Rate Loan;

                  (b) the failure of any Company to borrow, continue or convert
a Loan after such Company has given (or is deemed to have given) a Notice of
Borrowing or a Notice of Conversion/Continuation;

                  (c) the failure of any Company to make any prepayment in
accordance with any notice delivered under Section 2.06; or

                  (d) the prepayment or other payment (including after
acceleration thereof) of an Offshore Rate Loan on a day that is not the last day
of the relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained.

         3.05     Inability to Determine Rates. If the Agent or the Majority 
Banks determine that for any reason adequate and reasonable means do not exist
for determining the Offshore Rate for any requested Interest Period with respect
to a proposed Offshore Rate Loan, or that the Offshore Rate applicable pursuant
to subsection 2.08(a) for any requested Interest Period with respect to a
proposed Offshore Rate Loan does not adequately and fairly reflect the cost to
the Majority Banks of funding such Loan, the Agent will promptly so notify the
Companies and each Bank. Thereafter, the obligation of the Banks to make or
maintain Offshore Rate Loans, as the case may be, hereunder shall be suspended
until the Agent upon the instruction of the Majority Banks revokes such notice
in writing. Upon receipt of such notice, a Company may revoke any Notice of
Borrowing or Notice of Conversion/Continuation then submitted by it. If a
Company does not revoke such Notice, the Banks shall make, convert or continue
the Loans, as proposed by such Company, in the amount specified

                                       29
<PAGE>   36
in the applicable notice submitted by such Company, but such Loans shall be
made, converted or continued as Base Rate Loans instead of Offshore Rate Loans.

         3.06     Joint and Several Liability. The Companies covenant and agree 
that they are jointly and severally liable for payment of all sums due under
this Agreement and every other Loan Document and performance of all other
Obligations. The Companies agree that:

                  (a) A separate action or actions may be brought and prosecuted
against any Company whether action is brought against the other Companies or
whether the other Companies are joined in any such action or actions. Each
Company waives the benefit of any statute of limitations affecting its liability
hereunder.

                  (b) Each Company authorizes Agent and Banks, without notice or
demand and without affecting its liability hereunder, from time to time:

                      (1) to renew, compromise, extend, accelerate or otherwise
         change the time for payment, or otherwise change the terms, of the
         Obligations of the other Companies to Agent or to Banks, including
         increase or decrease of the rates of interest thereon, or otherwise
         change the terms of this Agreement with respect to such other
         Companies; and

                      (2) to release or substitute any one or more of any
         endorsers or guarantors of the Obligations.

                  (c) Each Company waives any right to require Agent and Banks:

                      (1) to proceed against any other Company or other Person;

                      (2) to exercise any right, assert any claim or demand, or
         proceed against or exhaust any security for any indebtedness to Agent
         and Banks under this Agreement; or

                      (3) to pursue any other remedy in Agent's, Banks', or any
         Bank's power whatsoever.

                  (d) Each Company waives any defense arising by reason of any
disability or other defense of any other Company, or the cessation from any
cause whatsoever of the liability of any other Company, whether consensual or
arising by operation of law or any bankruptcy, insolvency or debtor relief
proceeding, or from any other cause, or any claim that such Company's
Obligations exceed or are more burdensome than those of any other Company. Each
Company waives any defense arising by reason of any statute of limitations
affecting the liability of any other Company. Each Company waives all rights and
defenses arising out of an election of remedies by the Agent or any Bank.

                  (e) Each Company waives any right of subrogation,
reimbursement, indemnification, and contribution (contractual, statutory or
otherwise), including without limitation, any claim

                                       30
<PAGE>   37
or right of subrogation under the Bankruptcy Code or any successor statute,
against any Company arising from the existence or performance of its joint and
several liability.

                  (f) Each Company waives any right to enforce any remedy which
Agent and Banks now have or may hereafter have against any other Company, and
waives any benefit of, and any right to participate in, any security now or
hereafter held by Agent and Banks securing the Obligations.

                  (g) Each Company waives all presentments, demands for
performance, notices of nonperformance, protests, notices of protest, notices of
dishonor, and notices of the existence, creation, or incurring of new or
additional Obligations or any other indebtedness of each of the other Companies
to the Agent or any Bank.

                  (h) If any payment or transfer of any interest in property by
any Company to the Agent or any Bank in fulfillment of any Obligation is
rescinded or must at any time (including after the termination of the Banks'
commitments to extend credit under this Agreement) be returned, in whole or in
part, by the Agent or any Bank to such Company or any other Person, upon the
insolvency, bankruptcy or reorganization of such Company or otherwise, the
obligations under this Section shall be reinstated with respect to any such
payment or transfer, regardless of such termination.

         3.07     Survival. The agreements and obligations of the Companies in 
this Article III shall survive the payment of all other Obligations.

                                   ARTICLE IV

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         The Companies jointly and severally represent and warrant to the Agent
and each Bank that:

         5.01     Corporate Existence and Power. Each Company and each of its
Subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of the jurisdiction of its incorporation, is qualified
to do business in each other jurisdiction where the failure so to qualify would
have a material adverse effect on the business of such Company or its
operations, and has full corporate power, authority and legal right to carry on
its business as presently conducted, to own and operate its properties and
assets, and to execute, deliver and perform the Loan Documents.

         5.02     Corporate Authorization; No Contravention. The execution, 
delivery and performance by the Companies of this Agreement and each other Loan
Document to which each Company is party, and any borrowing under this Agreement
have been duly authorized by all necessary corporate action of the Companies,

                                       33
<PAGE>   40
and do not and will not require any shareholder approval or the approval or
consent of any trustee or the holders of any Indebtedness of any of the
Companies, except such as have been obtained and certified copies thereof
delivered to the Agent (in sufficient number of copies for each Bank) do not
contravene any law, regulation, rule or order binding on the Companies or their
Organization Documents and do not contravene the provisions of or constitute a
default under any indenture, mortgage, contract or other agreement or instrument
to which any Company or any of its Subsidiaries is a party or by which any
Company or any of its Subsidiaries or any of their properties may be bound or
affected.

         5.03     Governmental Approvals, Etc. No Government Approval or filing
or registration with or other action by or notice to any Governmental Authority
is required or necessary for the making and performance by, and enforcement
against, the Companies of this Agreement and the other Loan Documents or in
connection with any of the transactions contemplated hereby and thereby, except
such as have been heretofore obtained and are in full force and effect
(certified copies thereof having been delivered to the Agent in sufficient
number of copies for each Bank).

         5.04     Binding Effect. This Agreement and each other Loan Document to
which each Company is a party constitute the legal, valid and binding
obligations of such Company, enforceable against such Company in accordance with
their respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, or similar laws affecting the enforcement of creditors'
rights generally or by equitable principles relating to enforceability.

         5.05     Litigation. There are no actions, suits, proceedings,
investigations, disputes or claims against or affecting the Companies or any of
them now pending before any Governmental Authority or any arbitrator (nor to the
knowledge of the Companies has any thereof been threatened in writing) which (a)
purport to affect or pertain to this Agreement or any other Loan Document, or
any of the transactions contemplated hereby or thereby; and (b) if determined
adversely to any Company would be likely to have a Material Adverse Effect on
the financial condition or operations of the Companies or any of them, except as
reflected in the financial statements referred to in Section 5.06.

         5.06     Financial Condition.

                  (a) The financial statements of Penwest as included in
Penwest's most recent annual report on Form 10-K, relating thereto as filed with
the SEC for its fiscal year ended August 31, 1994, fairly present the financial
condition of Penwest and its Subsidiaries as at the dates thereof and the
results of operations of Penwest and its Subsidiaries for the periods then
ended, all in accordance with generally accepted accounting principles
consistently applied. Penwest and its Subsidiaries

                                       34
<PAGE>   41
did not have on such date any material contingent liabilities for taxes, unusual
forward or long-term commitments or unrealized or anticipated losses from any
unfavorable commitments, except as referred to or reflected or provided for in
such financial statements. As used in this subsection, "taxes" means any tax,
assessment, duty, levy, impost or other charge imposed by any Governmental
Authority on any Person or on any property, revenue, income, or franchise of any
Person and any interest or penalty with respect to any of the foregoing.

                  (b) Since August 31, 1994, there has been no Material Adverse
Effect other than the electrical downtime described in the Company's press
release of August 23, 1995.

         5.07     Title to Properties. Such Company and each Subsidiary have 
good record and marketable title in fee simple to, or valid leasehold interests
in, all real property necessary or used in the ordinary conduct of their
respective businesses, except for such defects in title as could not,
individually or in the aggregate, have a Material Adverse Effect. The property
of such Company and its Subsidiaries is subject to no Liens, other than
Permitted Liens.

         5.08     Taxes. Such Company and its Subsidiaries have filed all 
Federal and other material tax returns and reports required to be filed, and
have paid all Federal and other material taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable, except those which are being contested in good
faith by appropriate proceedings and for which adequate reserves have been
provided in accordance with GAAP. The charges, accruals and reserves on the
books of the Companies in respect of Taxes for all fiscal periods to date have
been computed in accordance with generally accepted accounting principles
consistently applied. There is no proposed tax assessment against such Company
or any Subsidiary that would, if made, have a Material Adverse Effect. There are
no questions or disputes between any of the Companies and any Governmental
Authority with respect to any taxes of a material amount except as disclosed in
the financial statements referred to in Section 5.06 or otherwise previously
disclosed to the Banks, through the Agent, in writing.

         5.09     No Event of Default. No Event of Default exists or would 
result from the incurring of any Obligations by such Company. Each Company and
each Subsidiary is not in default under or with respect to any Contractual
Obligation in any respect which, individually or together with all such
defaults, could reasonably be expected to have a Material Adverse Effect, or
that would, if such default had occurred after the Closing Date, create an Event
of Default under subsection 8.01(e).

         5.10     Use of Proceeds; Margin Regulations. The proceeds of the Loans
are to be used solely for the purposes set forth in and permitted by Section
6.01 and Section 7.08. None of the

                                       35
<PAGE>   42
Companies or any Subsidiary of any Company is generally engaged in the business
of purchasing or selling Margin Stock or extending credit for the purpose of
purchasing or carrying Margin Stock.

         5.11     Regulated Entities. None of the Companies, any Person 
controlling any Company, or any Subsidiary of any Company, is an "Investment
Company" within the meaning of the Investment Company Act of 1940. Each Company
is not subject to regulation under the Public Utility Holding Company Act of
1935, the Federal Power Act, the Interstate Commerce Act, any state public
utilities code, or any other Federal or state statute or regulation limiting its
ability to incur Indebtedness.

         5.12     ERISA Compliance.  Except as specifically disclosed in 
Schedule 5.12:

                  (a) Each Plan is in compliance in all material respects with
the applicable provisions of ERISA, the Code and other federal or state law.
Each Plan which is intended to qualify under Section 401(a) of the Code has
received a favorable determination letter from the IRS and to the best knowledge
of such Company, nothing has occurred which would cause the loss of such
qualification. Such Company and each ERISA Affiliate has made all required
contributions to any Plan subject to Section 412 of the Code, and no application
for a funding waiver or an extension of any amortization period pursuant to
Section 412 of the Code has been made with respect to any Plan.

                  (b) There are no pending or, to the best knowledge of Company,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan which has resulted or could reasonably be expected to
result in a Material Adverse Effect. There has been no prohibited transaction or
violation of the fiduciary responsibility rules with respect to any Plan which
has resulted or could reasonably be expected to result in a Material Adverse
Effect.

                  (c) (i) No ERISA Event has occurred or is reasonably expected
to occur; (ii) no Pension Plan has any Unfunded Pension Liability; (iii) neither
such Company nor any ERISA Affiliate has incurred, or reasonably expects to
incur, any liability under Title IV of ERISA with respect to any Pension Plan
(other than premiums due and not delinquent under Section 4007 of ERISA); (iv)
neither such Company nor any ERISA Affiliate has incurred, or reasonably expects
to incur, any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under
Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan; and (v)
neither such Company nor any ERISA Affiliate has engaged in a transaction that
could be subject to Section 4069 or 4212(c) of ERISA.

         5.13     Environmental Matters.  Such Company conducts in the ordinary 
course of business a review of the effect of existing

                                       36
<PAGE>   43
Environmental Laws and existing Environmental Claims on its business, operations
and properties, and as a result thereof such Company has reasonably concluded
that, except as specifically disclosed in Schedule 5.13, such Environmental Laws
and Environmental Claims could not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect.

         5.14     No Burdensome Restrictions. Neither such Company nor any
Subsidiary is a party to or bound by any Contractual Obligation, or subject to
any restriction in any Organization Document, or any Requirement of Law, which
could reasonably be expected to have a Material Adverse Effect. No Company or
any Subsidiary is in breach of or default under any agreement to which it is a
party or which is binding on it or any of its assets, which breach or default
could reasonably be expected to have a Material Adverse Effect.

         5.15     Copyrights, Patents, Trademarks and Licenses, etc. Such 
Company or its Subsidiaries own or are licensed or otherwise have the right to
use all of the patents, trademarks, service marks, trade names, copyrights,
contractual franchises, authorizations and other rights that are reasonably
necessary for the operation of their respective businesses, without conflict
with the rights of any other Person. To the best knowledge of such Company, no
slogan or other advertising device, product, process, method, substance, part or
other material now employed, or now contemplated to be employed, by such Company
or any Subsidiary infringes upon any rights held by any other Person. Except as
specifically disclosed in Schedule 5.15, no claim or litigation regarding any of
the foregoing is pending or threatened, and no patent, invention, device,
application, principle or any statute, law, rule, regulation, standard or code
is pending or, to the knowledge of such Company, proposed, which, in either
case, could reasonably be expected to have a Material Adverse Effect.

         5.16     Subsidiaries. Such Company has no Subsidiaries other than 
those specifically disclosed in part (a) of Schedule 5.16 hereto and has no
equity investments in any other corporation or entity other than those
specifically disclosed in part (b) of Schedule 5.16.

         5.17     Insurance. Except as specifically disclosed in Schedule 5.17, 
the properties of such Company and its Subsidiaries are insured with financially
sound and reputable insurance companies not Affiliates of such Company, in such
amounts, with such deductibles and covering such risks as are customarily
carried by companies engaged in similar businesses and owning similar properties
in localities where such Company or such Subsidiary operates.

         5.18     Full Disclosure. None of the representations or warranties 
made by such Company or any Subsidiary in the Loan Documents as of the date such
representations and warranties are

                                       37
<PAGE>   44
made or deemed made, and none of the statements contained in any exhibit,
report, statement or certificate furnished by or on behalf of such Company or
any Subsidiary in connection with the Loan Documents (including the offering and
disclosure materials delivered by or on behalf of such Company to the Banks
prior to the Closing Date), contains any untrue statement of a material fact or
omits any material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances under which they are
made, not misleading as of the time when made or delivered.

                                   ARTICLE VI

<PAGE>   58

the request of, or may, with the consent of, the Majority Banks,

                  (a) declare the commitment of each Bank to make Loans to be
terminated, whereupon such commitments shall be terminated;

                  (b) declare the unpaid principal amount of all outstanding
Loans, all interest accrued and unpaid thereon, and all other amounts owing or
payable hereunder or under any other Loan Document to be immediately due and
payable, without presentment, demand, protest or other notice of any kind, all
of which are hereby expressly waived by the Companies; and

                  (c) exercise on behalf of itself and the Banks all rights and
remedies available to it and the Banks under the Loan Documents or applicable
law;

provided, however, that upon the occurrence of any event specified in subsection
(f) or (g) of Section 8.01 (in the case of clause (i) of subsection (g) upon the
expiration of the 60-day period mentioned therein), the obligation of each Bank
to make Loans shall automatically terminate and the unpaid principal amount of
all outstanding Loans and all interest and other amounts as aforesaid shall
automatically become due and payable without further act of the Agent or any
Bank.

         8.03     Rights Not Exclusive. The rights provided for in this

any other rights, powers, privileges or remedies provided by law or in equity,
or under any other instrument, document or agreement now existing or hereafter

taking into account any extraordinary charge to earnings taken or to be taken as
of the end of any fiscal period of any Company (a "Charge"), and if solely by
virtue of such Charge, there would exist an Event of Default due to the breach
of any of Sections 7.11, 7.12, or 7.13 as of such fiscal period end date, such
Event of Default shall be deemed to arise upon the earlier of (a) the date after
such fiscal period end date on

                                       52
<PAGE>   59

date, the date that is such fiscal period end date, and (b) the date such
Company delivers to the Agent its audited annual or unaudited quarterly
financial statements in respect of such fiscal period reflecting such Charge as
taken.

                                   ARTICLE IX

                                    THE AGENT

         9.01     Appointment and Authorization; "Agent". Each Bank hereby
irrevocably (subject to Section 9.09) appoints, designates and authorizes the
Agent to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such duties
as are expressly delegated to it by the terms of this Agreement or any other
Loan Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

         9.02     Delegation of Duties. The Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

         9.03     Liability of Agent. None of the Agent-Related Persons shall 
(i) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Banks for any
recital, statement, representation or warranty made by any Company or any
Subsidiary or Affiliate of any Company, or any officer thereof, contained in
this Agreement or in any other Loan

                                       53
<PAGE>   60
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any Company or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Bank to ascertain or to inquire as
to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of any Company or any Subsidiaries or Affiliates of
any Company.

         9.04     Reliance by Agent.

                  (a) The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to any
Company), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the Majority Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Loan Document in accordance with a request or consent of the Majority
Banks and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Banks.

                  (b) For purposes of determining compliance with the conditions
specified in Section 4.01, each Bank that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Bank for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Bank.

         9.05     Notice of Default. The Agent shall not be deemed to have 
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Banks, unless the Agent shall
have received written notice from a Bank or a Company referring to this
Agreement, describing such Default or Event of Default and

                                       54
<PAGE>   61
stating that such notice is a "notice of default". The Agent will notify the
Banks of its receipt of any such notice. The Agent shall take such action with
respect to such Default or Event of Default as may be requested by the Majority
Banks in accordance with Article VIII; provided, however, that unless and until
the Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Banks.

         9.06     Credit Decision. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Companies and their Subsidiaries, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Bank. Each Bank
represents to the Agent that it has, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
credit worthiness of the Companies and their Subsidiaries, and all applicable
bank regulatory laws relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to the
Companies hereunder. Each Bank also represents that it will, independently and
without reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and credit worthiness of the Companies.
Except for notices, reports and other documents expressly herein required to be
furnished to the Banks by the Agent, the Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or credit worthiness of any Company which may come into the possession
of any of the Agent-Related Persons.

         9.07     Indemnification of Agent. Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Companies and without limiting the obligation of the Companies to do so), pro
rata, from and against any and all Indemnified Liabilities; provided, however,
that no Bank shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified Liabilities resulting solely from such Person's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Bank shall reimburse the Agent upon demand for its ratable share

                                       55
<PAGE>   62
of any costs or out-of-pocket expenses (including Attorney Costs) incurred by
the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the Agent
is not reimbursed for such expenses by or on behalf of the Companies. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Agent.

         9.08     Agent in Individual Capacity. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with any of the Companies and
their Subsidiaries and Affiliates as though BofA were not the Agent hereunder
and without notice to or consent of the Banks. The Banks acknowledge that,
pursuant to such activities, BofA or its Affiliates may receive information
regarding any Company, its Subsidiaries or Affiliates (including information
that may be subject to confidentiality obligations in favor of such Company,
Subsidiary, or Affiliate) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans, BofA
shall have the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent, and the terms "Bank" and
"Banks" include BofA in its individual capacity.

         9.09     Successor Agent. The Agent may, and at the request of the 
Majority Banks shall, resign as Agent upon 30 days' notice to the Banks. If the
Agent resigns under this Agreement, the Majority Banks shall appoint from among
the Banks a successor agent for the Banks. If no successor agent is appointed
prior to the effective date of the resignation of the Agent, the Agent may
appoint, after consulting with the Banks and Penwest, a successor agent from
among the Banks. Upon the acceptance of its appointment as successor agent
hereunder, such successor agent shall succeed to all the rights, powers and
duties of the retiring Agent and the term "Agent" shall mean such successor
agent and the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article IX and Sections 10.04 and 10.05 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement. If no successor agent has accepted appointment as Agent by
the date which is 30 days following a retiring Agent's notice of resignation,
the retiring Agent's resignation shall nevertheless thereupon become effective
and the Banks shall perform all of the duties of the Agent hereunder until such
time, if any, as the Majority Banks appoint a successor agent as provided for
above.

         9.10     Withholding Tax.

                  (a) If any Bank is a "foreign corporation, partnership or
trust" within the meaning of the Code, such Bank agrees with and in favor of the
Agent and the Companies, to deliver to the Agent and Penwest:

                      (1) if such Bank claims an exemption from withholding tax
         under a United States tax treaty, two properly completed and executed
         copies of IRS Form 1001 before the payment of any interest in the first
         calendar year and before the payment of any interest in each third
         succeeding calendar year during which interest may be paid under this
         Agreement;

                      (2) if such Bank claims that interest paid under this
         Agreement is exempt from United States withholding tax because it is
         effectively connected with a United States trade or business of such
         Bank, two properly completed and executed copies of IRS Form 4224
         before the payment of any interest is due in the first taxable year of
         such Bank and in each succeeding taxable year of such Bank during which
         interest may be paid under this Agreement; and

                      (3) such other form or forms as may be required under the
         Code or other laws of the United States as a condition to exemption
         from United States withholding tax;

unless there is a change in any treaty, law, regulation, or official
interpretation thereof which results in such Bank no longer being able to
deliver such a form or forms, and (y) with respect to a Bank party to this
Agreement as of the date of this Agreement, such change occurs after the date of
this Agreement, or (z) with respect to a Bank that becomes such after the date
of this Agreement, such change occurs after the date such Bank becomes a Bank
under this Agreement.

                  (b) No Bank shall sell, assign, delegate, grant a
participation in, or otherwise transfer all or part of the obligations of the
Companies to such Bank under this Agreement, or its commitment to extend credit
under this Agreement, to any Person that is not incorporated or organized under
the laws of the United States or a state thereof unless such Person first
delivers to Penwest the form or forms required by clauses (1), (2), and (3) of
subsection (a) of this Section.

                  (c) No Company shall be required to pay any additional amounts
pursuant to Section 3.01 if (i) the obligation to pay such additional amount
would not have arisen but for a failure by any Bank to comply with the
requirements of subsections (a) and (b) of this Section.

                  (d) If any Bank claims exemption from, or reduction of,
withholding tax under a United States tax treaty by providing

                                       57
<PAGE>   64
IRS Form 1001 and such Bank sells, assigns, grants a participation in, or
otherwise transfers all or part of the Obligations of the Companies to such
Bank, such Bank agrees to notify the Agent of the percentage amount in which it
is no longer the beneficial owner of Obligations of the Companies to such Bank.
To the extent of such percentage amount, the Agent will treat such Bank's IRS
Form 1001 as no longer valid.

                  (e) If any Bank claiming exemption from United States
withholding tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Companies to such Bank, such Bank agrees to undertake sole responsibility for
complying with the withholding tax requirements imposed by Sections 1441 and
1442 of the Code.

                  (f) If any Bank is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Bank
an amount equivalent to the applicable withholding tax after taking into account
such reduction. However, if the forms or other documentation required by
subsection (a) of this Section are not delivered to the Agent, then the Agent
may withhold from any interest payment to such Bank not providing such forms or
other documentation an amount equivalent to the applicable withholding tax
imposed by Sections 1441 and 1442 of the Code, without reduction.

                  (g) If the IRS or any other Governmental Authority of the
United States or other jurisdiction asserts a claim that the Agent did not
properly withhold tax from amounts paid to or for the account of any Bank
(because the appropriate form was not delivered or was not properly executed, or
because such Bank failed to notify the Agent of a change in circumstances which
rendered the exemption from, or reduction of, withholding tax ineffective, or
for any other reason) such Bank shall indemnify the Agent fully for all amounts
paid, directly or indirectly, by the Agent as tax or otherwise, including
penalties and interest, and including any taxes imposed by any jurisdiction on
the amounts payable to the Agent under this Section, together with all costs and
expenses (including Attorney Costs). The obligation of the Banks under this
subsection shall survive the payment of all Obligations and the resignation or
replacement of the Agent.

                                  MISCELLANEOUS

         10.01    Amendments and Waivers. No amendment or waiver of any 
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by the Companies (or any of them) therefrom, shall be
effective unless the same shall be in writing and signed by the Majority Banks
(or by the Agent at

                                       58
<PAGE>   65
the written request of the Majority Banks) and the Companies and acknowledged by
the Agent, and then any such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no such waiver, amendment, or consent shall, unless in writing and
signed by all the Banks and the Companies and acknowledged by the Agent, do any
of the following:

                  (a) increase or extend the Commitment of any Bank (or
reinstate any Commitment terminated pursuant to Section 8.02);

                  (b) postpone or delay any date fixed by this Agreement or any
other Loan Document for any payment of principal, interest, fees or other
amounts due to the Banks (or any of them) hereunder or under any other Loan
Document;

                  (c) reduce the principal of, or the rate of interest specified
herein on any Loan, or (subject to clause (ii) below) any fees or other amounts
payable hereunder or under any other Loan Document;

                  (d) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Loans which is required for the Banks
or any of them to take any action hereunder; or

                  (e) amend this Section, or Section 2.11, or any provision
herein providing for consent or other action by all Banks;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks or all the
Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Loan Document, and (ii) the Fee Letters may be amended,
or rights or privileges thereunder waived, in a writing executed by the parties
thereto.

         10.02    Notices.

                  (a) All notices, requests, consents, approvals, waivers and
other communications shall be in writing (including, unless the context
expressly otherwise provides, by facsimile transmission, provided that any
matter transmitted by any Company by facsimile shall be immediately confirmed by
a telephone call to the recipient at the number specified on Schedule 10.02, and
mailed, faxed or delivered, to the address or facsimile number specified for
notices on Schedule 10.02; or, as directed to any Company or the Agent, to such
other address as shall be designated by such party in a written notice to the
other parties, and as directed to any other party, at such other address as
shall be designated by such party in a written notice to the Companies and the
Agent.

                  (b) All such notices, requests and communications

                                       59
<PAGE>   66
shall be effective when transmitted and received in legible form by facsimile
machine, or if mailed, upon the third Business Day after the date deposited into
the U.S. mail, or if delivered, upon delivery; except that notices pursuant to
Article II or IX to the Agent shall not be effective until actually received by
the Agent.

                  (c) Any agreement of the Agent and the Banks herein to receive
certain notices by telephone or facsimile is solely for the convenience and at
the request of the Companies. The Agent and the Banks shall be entitled to rely
on the authority of any Person purporting to be a Person authorized by a Company
to give such notice and the Agent and the Banks shall not have any liability to
such Company or other Person on account of any action taken or not taken by the
Agent or the Banks in reliance upon such telephonic or facsimile notice. The
obligation of the Companies to repay the Loans shall not be affected in any way
or to any extent by any failure by the Agent and the Banks to receive written
confirmation of any telephonic or facsimile notice or the receipt by the Agent
and the Banks of a confirmation which is at variance with the terms understood
by the Agent and the Banks to be contained in the telephonic or facsimile
notice.

         10.03    No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Agent or any Bank, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

         10.04    Costs and Expenses.  The Companies shall:

                  (a) whether or not the transactions contemplated hereby are
consummated, pay or reimburse BofA (including in its capacity as Agent) within
30 Business Days after demand (subject to subsection 4.01(d)) for all costs and
expenses incurred by BofA (including in its capacity as Agent) in connection
with the preparation, delivery, administration and execution of, and any
amendment, supplement, waiver or modification to (in each case, whether or not
consummated), this Agreement, any Loan Document and any other documents prepared
in connection herewith or therewith, and the consummation of the transactions
contemplated hereby and thereby, including reasonable Attorney Costs incurred by
BofA (including in its capacity as Agent) with respect thereto; and

                  (b) pay or reimburse the Agent, the Arranger and each Bank
within five Business Days after demand (subject to subsection 4.01(d)) for all
costs and expenses (including Attorney Costs) incurred by them in connection
with the enforcement, attempted enforcement, or preservation of any rights or
remedies under this Agreement or any other Loan Document

                                       60
<PAGE>   67
during the existence of an Event of Default or after acceleration of the Loans
(including in connection with any "workout" or restructuring regarding the
Loans, and including in any Insolvency Proceeding or appellate proceeding).

         10.05    Companies Indemnification. Whether or not the transactions
contemplated hereby are consummated, the Companies shall indemnify, defend and
hold the Agent-Related Persons, and each Bank and each of its respective
officers, directors, employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including Attorney Costs) of any kind or
nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the
Agent or replacement of any Bank) be imposed on, incurred by or asserted against
any such Person in any way relating to or arising out of this Agreement or any
document contemplated by or referred to herein, or the transactions contemplated
hereby, or any action taken or omitted by any such Person under or in connection
with any of the foregoing, including with respect to any investigation,
litigation or proceeding (including any Insolvency Proceeding or appellate
proceeding) related to or arising out of this Agreement or the Loans or the use
of the proceeds thereof, whether or not any Indemnified Person is a party
thereto (all the foregoing, collectively, the "Indemnified Liabilities");
provided, that the Companies shall have no obligation hereunder to any
Indemnified Person with respect to Indemnified Liabilities resulting solely from
the gross negligence or willful misconduct of such Indemnified Person. The
agreements in this Section shall survive payment of all other Obligations.

         10.06    Payments Set Aside. To the extent that a Company makes a 
payment to the Agent or the Banks, or the Agent or the Banks exercise their
right of set-off, and such payment or the proceeds of such set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

         10.07    Successors and Assigns. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that a Company may not assign or
transfer any of its

                                       61
<PAGE>   68
rights or obligations under this Agreement without the prior written consent of
the Agent and each Bank. Each individual voluntary assignment by a Bank (other
than assignments by operation of law such as statutory assignments resulting
from mergers) shall be subject to Section 10.08.

         10.08    Assignments, Participations, etc.

                  (a) Any Bank may, with the written consent of the Companies at
all times other than during the existence of an Event of Default and the Agent,
which consents of the Companies shall not be unreasonably withheld, at any time
assign and delegate to one or more Eligible Assignees (provided that no written
consent of the Companies or the Agent shall be required in connection with any
assignment and delegation by a Bank to an Eligible Assignee that is an Affiliate
of such Bank and falling within clauses (a) or (b) of the definition of Eligible
Assignee) (each an "Assignee") all, or any ratable part of all, of the Loans,
the Commitments and the other rights and obligations of such Bank hereunder, in
a minimum amount of $10,000,000; provided, however, that the Companies and the
Agent may continue to deal solely and directly with such Bank in connection with
the interest so assigned to an Assignee until (i) written notice of such
assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall have been given to the Companies
and the Agent by such Bank and the Assignee; (ii) such Bank and its Assignee
shall have delivered to the Companies and the Agent an Assignment and Acceptance
in the form of Exhibit F ("Assignment and Acceptance") together with any Note or
Notes subject to such assignment and (iii) the assignor Bank or Assignee has
paid to the Agent a processing fee in the amount of $3,500.

                  (b) From and after the date that the Agent notifies the
assignor Bank that it has received (and provided its consent with respect to) an
executed Assignment and Acceptance and payment of the above-referenced
processing fee, (i) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Bank under the Loan Documents, and (ii) the assignor Bank shall, to the extent
that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.

                  (c) Within five Business Days after its receipt of notice by
the Agent that it has received an executed Assignment and Acceptance and payment
of the processing fee, (and provided that it consents to such assignment in
accordance with subsection 10.08(a)), the Companies, if so requested, shall
execute and deliver to the Agent, new Notes evidencing such Assignee's assigned
Loans and Commitment and, if the assignor Bank has

                                       62
<PAGE>   69
retained a portion of its Loans and its Commitment, replacement Notes in the
principal amount of the Loans retained by the assignor Bank (such Notes to be in
exchange for, but not in payment of, the Notes held by such Bank). Immediately
upon each Assignee's making its processing fee payment under the Assignment and
Acceptance, this Agreement shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The Commitment
allocated to each Assignee shall reduce such Commitments of the assigning Bank
pro tanto.

                  (d) Any Bank may at any time sell to one or more commercial
banks or other Persons not Affiliates of any of the Companies (a "Participant")
participating interests in any Loans, the Commitment of that Bank and the other
interests of that Bank (the "originating Bank") hereunder and under the other
Loan Documents; provided, however, that (i) the originating Bank's obligations
under this Agreement shall remain unchanged, (ii) the originating Bank shall
remain solely responsible for the performance of such obligations, (iii) the
Companies and the Agent shall continue to deal solely and directly with the
originating Bank in connection with the originating Bank's rights and
obligations under this Agreement and the other Loan Documents, and (iv) no Bank
shall transfer or grant any participating interest under which the Participant
has rights to approve any amendment to, or any consent or waiver with respect
to, this Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would require unanimous consent of the Banks as
described in the first proviso to Section 10.01. In the case of any such
participation, the Participant shall be entitled to the benefit of Sections
3.01, 3.03 and 10.05 as though it were also a Bank hereunder (except to the
extent the Participant has the right to greater compensation or payments or may
be excused from obligations under any of such sections, in any case, at the time
of such sale), and if amounts outstanding under this Agreement are due and
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall be deemed to have
the right of set-off in respect of its participating interest in amounts owing
under this Agreement to the same extent as if the amount of its participating
interest were owing directly to it as a Bank under this Agreement.

                  (e) Notwithstanding any other provision in this Agreement, any
Bank may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement and the Note held by
it in favor of any Federal Reserve Bank in accordance with Regulation A of the
FRB or U.S. Treasury Regulation 31 CFR Section 203.14, and such Federal
Reserve Bank may enforce such pledge or security interest in any manner
permitted under applicable law.

         10.09    Confidentiality. Each Bank agrees to take and to

                                       63
<PAGE>   70
cause its Affiliates to take normal and reasonable precautions and exercise due
care to maintain the confidentiality of all information identified as
"confidential" or "secret" by a Company and provided to it by such Company or by
the Agent on such Company's behalf, under this Agreement or any other Loan
Document, and neither it nor any of its Affiliates shall use any such
information other than in connection with or in enforcement of this Agreement
and the other Loan Documents or in connection with other business now or
hereafter existing or contemplated with such Company; except to the extent such
information (i) was or becomes generally available to the public other than as a
result of disclosure by the Bank, or (ii) was or becomes available on a
non-confidential basis from a source other than such Company, provided that such
source is not bound by a confidentiality agreement with such Company known to
the Bank; provided, however, that any Bank may disclose such information (A) at
the request or pursuant to any requirement of any Governmental Authority to
which the Bank is subject or in connection with an examination of such Bank by
any such authority; (B) pursuant to subpoena or other court process; (C) when
required to do so in accordance with the provisions of any applicable
Requirement of Law; (D) to the extent reasonably required in connection with any
litigation or proceeding to which the Agent, any Bank or their respective
Affiliates may be party; (E) to the extent reasonably required in connection
with the exercise of any remedy hereunder or under any other Loan Document; (F)
to such Bank's independent auditors and other professional advisors; (G) to any
Participant or Assignee, actual or potential, provided that such Person agrees
in writing to keep such information confidential to the same extent required of
the Banks hereunder; (H) as to any Bank or its Affiliate, as expressly permitted
under the terms of any other document or agreement regarding confidentiality to
which such Company or any Subsidiary is party or is deemed party with such Bank
or such Affiliate; and (I) to its Affiliates.

         10.10    Set-off. In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to any Company, any such notice being waived by the Companies to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of any Company against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Loan Document and although
such Obligations may be contingent or unmatured. Each Bank agrees promptly to
notify the relevant Company and the Agent after any such set-off and application
made by such Bank; provided, however, that the failure to give such notice shall
not affect the validity of such set-off and application.

                                       64
<PAGE>   71
         10.11    Notification of Addresses, Lending Offices, Etc. Each Bank 
shall notify the Agent in writing of any changes in the address to which notices
to the Bank should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

         10.12    Counterparts. This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

         10.13    Severability. The illegality or unenforceability of any 
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

         10.14    No Third Parties Benefited. This Agreement is made and entered
into for the sole protection and legal benefit of the Companies, the Banks, the
Agent and the Agent-Related Persons, and their permitted successors and assigns,
and no other Person shall be a direct or indirect legal beneficiary of, or have
any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

         10.15    Governing Law and Jurisdiction.

                  (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA; PROVIDED THAT
THE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

                  (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE
OF CALIFORNIA OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF CALIFORNIA,
AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE COMPANIES, THE
AGENT AND THE BANKS CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
NONEXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE COMPANIES, THE AGENT AND
THE BANKS IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY

JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO. THE
COMPANIES, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS,
COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY
CALIFORNIA LAW.

         10.16     Waiver of Jury Trial.  THE COMPANIES, THE BANKS AND THE AGENT
EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF OR

                                       65
<PAGE>   72
RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF

AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL
WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT
THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION

PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER
LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO

  and Savings Association

San Francisco, California 94103


Ladies and Gentlemen:

        We have acted as counsel for Penwest, Ltd., a Washington corportion
("Penwest"), Penford Products Co., a Delaware corporation ("Penford") and
Edward Mendell Co., Inc., a Washington corporation ("Mendell") in connection
with the Credit Agreement (the "Credit Agreement") dated as of December ___,
1995 among Penwest, Penford and Mendell (each, a "Company"), Bank of America
National Trust and Savings Association, as Agent (the "Agent"), and the
financial institutions named on the signature pages thereof (each, a "Bank").
This opinion letter is being rendered to you at the request of our clients as
contemplated by Section 4.01(c) of the Credit Agreement. Capitalized terms not
otherwise defined herein are used herein as defined in the Credit Agreement.

        We have examined originals or copies, certified or otherwise identified
to our satisfaction, of:

                (a) the Credit Agreement, which states that it is governed by
        the laws of California;

                (b) the Notes(1), which state that they are governed by the
        laws of California;

                (c) the articles or certificate of incorporation of each Company
        and amendments thereto, certified by the offices of the Secretaries of 
        State of Washington and Delaware as being true and correct as of 
        December __, 1995 and December __, 1995, respectively; a Certificate
        of Existence/Authorization issued on December __, 1995 by the office of
        the Secretary of State of Washington with respect to each Company, and a
        Certificate issued on December __,

there is only one Note.

        1995 by the ofice of the Secretary of State of Delaware with respect to
        Penford; and

                (d)  the bylaws of each Company, certified by an officer of
        such Company as being true and correct as of the date hereof;

and we have conducted such other investigations of law as we have deemed
necessary or advisable for purposes of this opinion letter.

                We have assumed without independent verification:

                (a)  the genuineness of all signatures, the authenticity of all
        documents, instruments and certificates submitted to us as originals,
        and the exact conformity with the executed originals of all documents,
        instruments and certificatfes submitted to us as copies; and

                (b)  that the execution, delivery and performance of the Credit
        Agreement by the Agent and each Bank have been duly authorized by all
        necessary corporate and other action and that the Agent and each Bank
        has executed and delivered the Credit Agreement.

                As to questions of fact material to this opinion letter, we 
have relied without independent verification solely upon the documents, 
instruments and certificates submitted to us.

                Whenever a statement herein is qualified by "to our knowledge" 
or a similar phrase, it is intended to indicate that, during the course of our
representation of the Companies, no information that would give us current
actual knowledge of the inaccuracy of such statement has come to our attention. 
However, we have not undertaken any independent investigation to determine the
accuracy of such statement, and any limited inquiry undertaken by us during the
preparation of this opinion letter should not be regarded as such an
investigation; no inference as to our knowledge of any matters bearing on the
accuracy of any such statement should be drawn from the fact of our
representation of the Companies.

                We are qualified to practice law in the State of Washington and
do not express any opinion in this letter concerning any laws other than the 
laws of the State of Washington, the General Corporation Law of the State of 
Delaware and the federal laws of the United States.  Without limiting the 
generality of the foregoing, we express no opinion as to the effect (if any) 
of any law of any jurisdiction in which any Bank

is located which limits the rate of interest that such Bank may charge or
collect.

        Based upon and subject to the foregoing, and further subject to the
qualifications set forth below, we are of the opinion that:

        1.  Each of Penwest and Mendell is a corporation duly incorporated,
validly existing and authorized to transact business in the corporate form
under the laws of the State of Washington.  Penford is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware, and is duly qualified to do business as a foreign corporation in
the State of Washington.  Each of the Companies has the corporate power and
authority required to carry on its business as presently conducted, to own and
operate its properties and assets and to execute, deliver and perform the
Credit Agreement and the Notes.

        2.  The execution, delivery and performance by each Company of the
Credit Agreement and the Notes made by it are within the corporate powers of
such Company, have been duly authorized by all necessary corporate action on
the part of such Company, do not require any shareholder approval, do not
contravene or constitute a default under (i) any applicable law, regulation or
rule, or any order known to us to be binding on such Company; (ii) the
articles of incorporation or bylaws of such Company; (iii) any applicable law
or regulation or (iv) to our knowledge, any indenture, mortgage, contract or
other agreement or instrument to which such Company is a party or by which such
Company or any of its properties is bound.

        3.  No approval, permit, license, authorization, certificate or
consent of any Washington State or federal governmental authority is required
or necessary for any Company in connection with the execution and delivery of
the Credit Agreement and the Notes made by it.

        4.  If the Credit Agreement and the Notes were by their terms governed
by the laws of the State of Washington, the Credit Agreement would constitute a
legal, valid and binding agreement of each Company, and each Note would
constitute a legal, valid and binding obligation of the Company that made such
Note, in each case enforceable against such Company in accordance with its
terms.

        5.  To our knowledge, except as described in the attachment hereto or
otherwise disclosed to the Banks, there is

no action, suit or proceeding pending against or affecting any Company before
any court or arbitrator or any governmental body, agency or official which
purports to affect the validity of the Credit Agreement or any Note or in which
there is a reasonable likelihood of an adverse decision which would materially
adversely affect the financial condition or results of operations of Penwest
and its Subsidiaries, taken as a whole.

        6.  Neither any Company nor any Subsidiary of any Company is (i) an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, (ii) a "holding company," an "affiliate" of a holding company or a
"subsidiary" of a holding company within the meaning of the Public Utility
Holding Company Act of 1935, as amended, or (iii) a "public service company"
within the meaning of Section 80.08 of the Revised Code of Washington, as
amended.

        7.  Neither any Company nor any Subsidiary of any Company is generally 
engaged in the business of purchasing or selling Margin Stock or extending 
credit for the purpose of purchasing or carrying Margin Stock.

        The opinions expressed above are subject to the following
qualifications:

        (a)  The validity and enforceability of obligations and the
availability of rights and remedies are subject to and may be limited by (i)
laws relating to or affecting creditors' rights generally (including but not
limited to bankruptcy, insolvency, reorganization, arrangement and moratorium
laws), (ii) Section 548 of the United States Bankruptcy Code, state fraudulent
transfer laws and other similar laws relating to fraud on creditors
("Fraudulent Conveyance Laws") and (iii) general principles of equity
(including but not limited to concepts of materiality, reasonableness, good
faith and fair dealing and principles that may limit the availability of
specific performance or injunctive or other equitable relief), whether the
validity or enforceability of obligations or the availability of rights and
remedies may be considered in a proceeding in equity or at law.

        (b)  Though we express no opinion as to the effect of any Fraudulent
Conveyance Laws, we call your attention to the fact that Fraudulent Conveyance
Laws would likely be implicated by certain aspects of the proposed
transactions, including without limitation the assumption by each Company of
liability for indebtedness incurred by other Companies without receiving the
benefit of the proceeds thereof. The effect of Fraudulent Conveyance Laws
depends upon the solvency and adequacy of capital

of, and other factual matters relating to, the Companies, after giving effect to
the transactions contemplated by the Credit Agreement. We have not undertaken a
review of such factual matters.

        (c)  We express no opinion as to any provision in the Credit Agreement
or any Note insofar as it purports to provide that any party (i) may have
rights to indemnification or contribution, (ii) may have set-off or similar
rights, (iii) waives any right or defense or (iv) is entitled to payment of
attorneys' fees in any action or proceeding although it is not the prevailing
party or is entitled to attorneys' fees except to the extent determined by a
court to be reasonable.

        (d)  We express no opinion as to any federal or state securities laws.

        This opinion letter is being rendered to the Agent and the Banks and is
intended solely for their benefit for use in connection with the matters
addressed herein, and may not be relied upon by the Agent or any Bank for any
other purpose, or relied upon by any other person or entity for any purpose,
without our prior written consent.

                                        Very truly yours,

            (b)   The [Assignor] [Assignee] further agrees to pay to

<PAGE>   109
the Agent a processing fee in the amount specified in Section 10.08(a) of the
Credit Agreement.

      3.    Reallocation of Payments.

respect to the Commitment and Loans shall be for the account of the Assignor.
Any interest, fees and other payments accrued on and after the Effective Date
with respect to the Assigned Amount shall be for the account of the Assignee.
Each of the Assignor and the Assignee agrees that it will hold in trust for the
other party any interest, fees and other amounts which it may receive to which
the other party is entitled pursuant to the preceding sentence and pay to the
other party any such amounts which it may receive promptly upon receipt.
