PART I

ITEM 1:  BUSINESS

a)   GENERAL:

Penford Corporation (Penford or the Company) was incorporated under the name
PENWEST, LTD. in September 1983 and commenced operations on March 1, 1984.  In
connection with the plan described below, PENWEST, LTD. changed its name to
Penford Corporation.

Penford consists of the following business units:

       -      Penford Products Co. (specialty carbohydrate chemicals for
              papermaking) - The history of Penford Products Co. can be traced
              to 1894. Penford Products Co. operates as a wholly-owned
              subsidiary of Penford.

       -      Penwest Pharmaceuticals Co. (controlled release technology and
              pharmaceutical excipients) - In March 1991, Penford purchased the
              net assets of Edward Mendell Co., Inc. (Mendell). In connection
              with the plan discussed below, Mendell changed its name to Penwest
              Pharmaceuticals Co. (Penwest). Penwest is a wholly-owned
              subsidiary of Penford.

       -      Penford Food Ingredients Co. (specialty food ingredient products)
              - In September 1991, Penford Food Ingredients Co. (formerly 
              Penwest Foods Co.) was established to manufacture and market 
              specialty carbohydrate-based food ingredients. Penford Food 
              Ingredients is a division of Penford Products Co.

On October 9, 1997, Penford announced a two stage plan designed to foster the
growth potential of its pharmaceuticals business and separately, its paper and
food ingredients businesses.  Under the first stage of the plan, Penwest
Pharmaceuticals Co. would sell up to 20% of its common stock through an initial
public offering.  Under the second stage of the plan, Penford would effect a
tax-free spin-off to its shareholders of its remaining ownership of Penwest
common shares, contingent upon satisfying certain conditions, including receipt
of a tax ruling from the Internal Revenue Service or a written opinion from
Ernst & Young LLP to the effect that, among other things, the spin-off will
qualify as a tax-free distribution.  The spin-off is anticipated to occur in
the second quarter of calendar 1998.  If the spin-off occurs, Penwest will no
longer be a subsidiary of Penford.

On October 21, 1997, Penwest filed a registration statement with the Securities
and Exchange Commission for an initial public offering of 2,500,000 shares of
common stock (approximately 15% of its outstanding common stock).  The estimated
initial public offering price is between $10.00 to $12.00 per share.  An option
will be granted to the underwriters to purchase up to 375,000 additional shares
for the purpose of covering over-allotments, if any.  Penford and Penwest have
entered into a Separation Agreement setting forth the agreement of the parties
with respect to the principal corporate transactions required to effect the
separation of Penford's pharmaceutical business from its paper and food
ingredients businesses, the initial public offering and the spin-off, and
certain other agreements governing the relationship of the parties prior to and
after the spin-off.  Penford and Penwest will, prior to the completion of the
initial public offering, also enter into other agreements that govern various
interim and ongoing relationships.

b)       FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS:

The Company's single business segment is developing, manufacturing and
marketing carbohydrate-based specialty chemicals.  These carbohydrate- based
specialty chemicals are marketed and sold to three industries:  paper,
pharmaceuticals and food.



                                     Page 3
<PAGE>   4
c)   DESCRIPTION OF BUSINESS:


BUSINESS UNITS

1.   SPECIALTY CHEMICALS:  PENFORD PRODUCTS CO. (PENFORD PRODUCTS) develops,
manufactures and markets carbohydrate-based specialty chemical starches for
papermaking.  These starches are principally ethylated (chemically modified
with ethylene oxide) and cationic (carrying a positive electrical charge)
starches.  Ethylated starches are used in coatings and as binders, providing
strength and printability to fine white, magazine and catalog paper.  Cationic
starches are used at the "wet-end" of the paper machine, providing strong
internal bonding of paper fibers.  In addition, Penford Products' starch
copolymers, a patented combination of synthetic and natural carbohydrate
chemistry, are used in coating and binder applications in various segments of
the paper industry.  Starches produced by Penford Products are designed to
improve the strength, quality and runnability of coated and uncoated paper.

Penford Products' corn-based ethylated and cationic starches and starch
copolymers are produced at its Cedar Rapids, Iowa facility.  Penford Products'
potato-based cationic starches are produced at its Idaho Falls, Idaho facility.

Penford Products also sells specialty starch products to the domestic textile
industry for warp sizing, which is a fiber bonding process for yarn and
finished fabric, and for fabric sizing, which provides body and stiffness to
textiles.

Specialty chemical brand names of Penford Products for the paper industry
include, among others, Penford(R) Gums, PENSIZE(R) and the Apollo(R) series.

Penford Products' specialty chemicals for the paper industry are manufactured
by a process known as corn wet milling, which is the process by which the
various parts of corn are separated, refined and modified.

The corn, after it is removed from the cob and cleaned, is placed in warm
steepwater treated with sulfur dioxide, which causes the corn to swell and
soften.  The softened kernels pass through a mill which separates the corn's
germ from its endosperm which contains the starch found in finished products.
Water is added, producing a thick slurry.

The germ is then separated from the slurry.  After the germ has been washed and
dried, the crude corn oil contained in the germ is removed and refined,
yielding a fine quality salad and cooking oil, or a raw material for corn oil
margarines.  Germ meal is used in animal feed.  The remaining mixture of hull
and endosperm is then processed.  Hull particles are screened out for animal
feed, while the finer particles of gluten and starch pass through.  The corn
oil, germ meal and hull particles are all sold as by-products.

The water slurry of starch and gluten is separated.  The starch, which is more
than 99 percent pure, is washed a third time to remove small quantities of
solubles.  Modified starches are created by adding chemical reagents and
catalysts to the pure starch slurry.  The modified starch is then filtered and
dried and is ready for shipping.

2.   PHARMACEUTICALS:  PENWEST PHARMACEUTICALS CO. (Penwest) is engaged in the 
research, development and commercialization of novel drug delivery 
technologies.  Penwest has developed its proprietary TIMERx (R) controlled 
release drug delivery technology.  Penwest has applied TIMERx technology to 
the development of oral formulations of generic versions of controlled release 
drugs and branded controlled release versions of immediate release drugs.  
Each of these formulations has been developed under a collaborative arrangement
with a pharmaceutical company.  These formulations are in various stages of
development and are subject to regulatory approval.  Except for Cystrin CR(R)
(described below), no product based on TIMERx technology has ever received
regulatory approval for commercial sale.  There can be no assurance that
Penwest's controlled release product development efforts will be successfully
completed, that required regulatory approvals will be obtained or that approved
products will be successfully manufactured or marketed.

In October 1997, Penwest's collaborator, Leiras OY, a Finnish subsidiary of
Schering AG, received marketing approval in Finland for Cystrin CR(R) for the
treatment of urinary incontinence.





                                     Page 4
<PAGE>   5
In May 1997, Penwest's collaborator, Mylan Pharmaceuticals Inc. (Mylan), filed
an abbreviated new drug application (ANDA) with the U.S. Food and Drug
Administration (FDA) for the first generic version of the 30 mg dosage strength
of Procardia XL(R), a leading cardiovascular drug for angina and hypertension.

Penwest also manufactures and distributes excipients to the pharmaceutical and
nutritional industries.  Excipients are the inactive ingredients in tablets and
capsules that enable tabletting of active drug ingredients by enhancing
binding, lubrication and disintegration properties.  Penwest's largest selling
excipient product is EMCOCEL(R), a tabletting binder.  In fiscal 1997, Penwest
introduced PROSOLV SMCC(TM), which Penwest believes represents a new class of
high functionality binders.  Other excipient brand names include EMCOMPRESS(R),
EMDEX(R), EXPLOTAB(R) and PRUV(R).

Penwest operates facilities at Patterson, New York, Nastola, Finland, and Cedar
Rapids, Iowa.

3.   SPECIALTY FOOD INGREDIENT PRODUCTS:  PENFORD FOOD INGREDIENTS CO. (PFI)
develops, manufactures and markets specialty food ingredients to the food and
confectionery industries.  These ingredients include food grade potato and
tapioca starch products as well as dextrose-based products such as specialty
dried corn syrup.  PFI is the only North American producer of food grade potato
and tapioca starches.

PFI, headquartered in Englewood, Colorado, maintains manufacturing facilities at
Richland, Washington and Plover, Wisconsin for the food grade potato and tapioca
starches, and at Cedar Rapids, Iowa for the dextrose products.  Penford Food
Ingredients' product brand names include CanTab(R), CarriDex(TM) and PenPlus(R).

RAW MATERIALS

Corn:  The Penford Products corn wet milling plant is located in Cedar Rapids,
Iowa, the middle of the U.S. corn belt.  Accordingly, the plant has truck and
rail delivered corn available throughout the year from a large number of corn
dealers and farmers at prices related to the major U.S. grain markets.  The
cost of the corn to be purchased for fixed price business is generally hedged
by entering into futures contracts.

Cellulose Wood Pulp:  Penwest's facilities at Nastola, Finland and Cedar
Rapids, Iowa use high-grade dissolving wood pulp (cellulose) as their primary
raw material to manufacture microcrystalline cellulose (EMCOCEL(R)).  Penwest's
supplier of cellulose is located in North America.

Xanthan and Locust Bean Gums:  Penwest's TIMERx drug delivery system consists
primarily of two natural polysaccharides, xanthan and locust bean gums.
Penwest purchases these gums from a sole source supplier.

Potato Starch:  The Idaho Falls, Idaho facility of Penford Products and the
Richland, Washington facility of Penford Food Ingredients use co-products from
potato processors that contain the starch used as the primary raw material to
manufacture modified potato starches for papermaking and food applications.
Suppliers of the raw material are located in North America, primarily in the
northwest and midwest.

Chemicals:  The principal chemical used in modifying starch is ethylene oxide,
a petrochemical derivative.  Ethylene oxide is a commodity chemical, subject to
price fluctuations due to market conditions.

Corn, cellulose, xanthan and locust bean gums, potato starch and ethylene oxide
are not generally subject to availability constraints.

Approximately half of total manufacturing costs are the costs of corn,
cellulose, xanthan and locust bean gums, potato starch and chemicals.  The
remaining portion consists primarily of utility and labor costs.

PATENTS, TRADEMARKS AND TRADENAMES

The Company owns several patents, trademarks, and tradenames.  Penwest has been
issued 17 U.S. patents and 40 foreign patents relating to its controlled
release drug delivery technology.  These patents





                                     Page 5
<PAGE>   6

expire between 2008 and 2015.  There can be no assurance that these patents
will prevent other companies from developing similar or functionally equivalent
products or from successfully challenging the validity of these patents.
Further, there can be no assurance that the Company's processes or products
will not infringe the patents of third parties.

RESEARCH AND DEVELOPMENT

Company-sponsored research and development costs of $8,057,000, $7,297,000 and
$6,773,000 in fiscal 1997, 1996 and 1995, respectively, were charged to expense
as incurred.

ENVIRONMENTAL MATTERS

The Company has adopted a Policy on Environmental Matters and has implemented a
comprehensive corporate-wide environmental management program.  The program is
managed by the Corporate Director of Environmental, Health and Safety and is
intended to ensure the Company's business is conducted in a safe and fiscally
responsible manner that protects and preserves the health and safety of Company
employees, the communities surrounding the Company's plants and the
environment.  The Company continues to monitor environmental legislation and
regulations which may affect its operations.

WORKING CAPITAL

Working capital requirements of the Company are financed through operating cash
flow, unsecured lines of credit, and an unsecured $35 million credit agreement.
There was $20.3 million outstanding under the credit agreement at August 31,
1997.  The Company also had uncommitted lines of credit totaling $15 million
under which $6.0 million was outstanding at fiscal year end.

PRINCIPAL CUSTOMERS

The Company sells to approximately ninety major customers.  Two customers,
Georgia Pacific and Mead Paper, accounted for approximately 15% and 10%,
respectively, of total sales in fiscal 1997.

COMPETITION

The Company competes with approximately five other companies that manufacture
corn wet milling products, none of which is dominant in the ethylated starch
business. Although Penford Products is one of the smaller corn wet millers, it
is one of the major producers of specialty ethylated starches.  Quality,
service and price are the major competitive factors for Penford Products.

The Company competes with numerous other companies that manufacture or
distribute pharmaceutical excipients.  Penwest's principal competitor in this
market is FMC Corporation.  Penwest has the second largest market share in
sales of its primary excipient product, EMCOCEL(R), or microcrystalline
cellulose.  Quality, service and price are the major competitive factors for
Mendell.

The Company competes with numerous other companies in developing controlled
release drug delivery systems for the pharmaceutical industry.  Development
expertise and proprietary technology are the major competitive factors for
Penwest's controlled release drug delivery business.

The Company competes with approximately four other companies that manufacture
specialty food ingredients, all of whom have larger market shares.  Application
expertise, quality, service and price are the major competitive factors for
Penford Food Ingredients.

EMPLOYEES

At October 17, 1997, Penford and its subsidiaries had 533 employees.  Penford's
specialty chemical and food ingredients operations, pharmaceuticals operations
and executive office employed 398, 118 and 17 persons, respectively.
Approximately 40% of the employees are represented by unions.  Management
believes its employee relations are good, with the most recent collective
bargaining agreement completed in July, 1997.





                                     Page 6
<PAGE>   7
METHODS OF DISTRIBUTION

Penford Products, Penford Food Ingredients and Penwest use a direct sales force
to market their products in North America.

Penwest uses a combination of direct sales and distributors to market its
excipient products outside North America.  Pursuant to Penwest's collaborative
agreements, Penwest's collaborators have responsibility for the marketing and
distribution of controlled release pharmaceuticals using TIMERx technology.

Penford Products' customers may purchase products through fixed-price contracts
or formula-priced contracts for periods covering three months to five years or
on a spot basis.  Sales are approximately equally divided between fixed and
formula price business with a remaining 10% consisting of spot sales.  Products
are shipped in either a bulk or bagged format.

D)   FOREIGN OPERATIONS AND EXPORT SALES:

Penwest has a facility in Nastola, Finland.  This operation is not significant
to the consolidated Company.  Sales from this facility were less than 5% of the
Company's total sales in fiscal 1997.  Export sales have accounted for less than
10% of the Company's total sales during each of the last three fiscal years.

ITEM 3:  LEGAL PROCEEDINGS

In May 1997, one of Penwest's collaborators, Mylan, filed an ANDA with the FDA
for the 30 mg dosage strength of Nifedipine XL, a generic version of Procardia
XL.  Bayer AG (Bayer) and ALZA Corporation (ALZA) own patents listed for
Procardia XL (the last of which expires in 2010), and Pfizer Inc. (Pfizer)
holds the new drug application and markets the product.  In connection with the
ANDA filing, Mylan certified to the FDA that Nifedipine XL does not infringe
these Bayer or ALZA patents and notified Bayer, ALZA and Pfizer of such
certification.  Bayer and Pfizer sued Mylan in the United States District Court
for the Western District of Pennsylvania, alleging that Mylan's product
infringes Bayer's patent.  Penwest has been informed by Mylan that ALZA does
not believe that the notice given to it complied with the requirements of the
"Waxman-Hatch Act," which governs the filing of ANDAs.  Mylan has advised the
Company that it intends to contest vigorously the allegations made in the
lawsuit.  Delays in the commercialization of Nifedipine XL could occur because
the FDA will not grant final marketing approval of Nifedipine XL until a final
judgment on the patent suit is rendered in favor of Mylan by the district
court, or in the event of an appeal, by the court of appeals, or until 30
months (or such longer or shorter period as the court may determine) have
elapsed from the date of Mylan's certification, whichever is sooner.

In 1993, Pfizer filed a "citizen's petition" with the FDA, claiming that its
Procardia XL formulation constituted a unique delivery system and that a drug
with a different release mechanism such as the TIMERx controlled release system
cannot be considered the same dosage form and approved in an ANDA as
bioequivalent to Procardia XL.  In August 1997, the FDA rejected Pfizer's
citizen's petition.  In July 1997, Pfizer also sued the FDA in the District
Court of the District of Columbia, claiming that the FDA's acceptance of
Mylan's ANDA filing for Nifedipine XL was contrary to law, based primarily on
the arguments stated in its citizen's petition.  Mylan and Penwest have
intervened as defendants in this suit.  An outcome adverse to Mylan and Penwest
would result in Mylan being required to file a suitability petition in order to
maintain the ANDA filing or to file an NDA with respect to Nifedipine XL, each
of which would be expensive and time consuming.  An adverse outcome also would
result in Nifedipine XL becoming ineligible for an "AB" rating from the FDA.
Failure to obtain an AB rating from the FDA would indicate that for certain
purposes Nifedipine XL would not be deemed to be therapeutically equivalent to
the referenced branded drug and would not be relied upon by Medicaid and
Medicare formularies for reimbursement.  If any of such events occur, Mylan may
terminate its efforts with respect to Nifedipine XL.

ITEM 4:  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 7:      MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
             AND RESULTS OF OPERATIONS


Recent Developments

On October 9, 1997, Penford announced a two stage plan designed to foster the
growth potential of its pharmaceuticals business and separately, its paper and
food ingredients businesses.  Under the first stage of the plan, Penwest
Pharmaceuticals Co. would sell up to 20% of its common stock through an initial
public offering.  Under the second stage of the plan, Penford would effect a
tax-free spin-off to its shareholders of its remaining ownership of Penwest
common shares, contingent upon satisfying certain conditions, including receipt
of a tax ruling from the Internal Revenue Service or a written opinion from
Ernst & Young LLP to the effect that, among other things, the spin-off will
qualify as a tax-free distribution.  The spin-off is anticipated to occur in
the second quarter of calendar 1998.  If the spin-off occurs, Penwest will no
longer be a subsidiary of Penford.

On October 21, 1997, Penwest filed a registration statement with the Securities
and Exchange Commission for an initial public offering of 2,500,000 shares of
common stock (approximately 15% of its outstanding common stock).  The estimated
initial public offering price is between $10.00 to $12.00 per share.  An option
will be granted to the underwriters to purchase up to 375,000 additional shares
for the purpose of covering over-allotments, if any.  Penford and Penwest have
entered into a Separation Agreement setting forth the agreement of the parties
with respect to the principal corporate transactions required to effect the
separation of Penford's pharmaceutical business from its paper and food
ingredients businesses, the initial public offering and the spin-off, and
certain other agreements governing the relationship of the parties prior to and
after the spin-off.  Penford and Penwest will, prior to the completion of the
initial public offering, also enter into other agreements that govern various
interim and ongoing relationships.

Penwest will retain the proceeds from the planned initial public offering.  In
addition, Penford will forgive all intercompany advances as of the closing of
the offering.  As of August 31, 1997, the intercompany balance approximated
$35.2 million.  Had the proposed plan been effected as of August 31, 1997, it is
estimated that consolidated assets and shareholders' equity of Penford would
have reflected a reduction of approximately $35.0 to $40.0 million, representing
the net effects of the proposed distribution.

Comparison of Fiscal 1997 to 1996 Results of Operations

Sales increased $2.2 million or 1.1% in fiscal 1997.  The increase reflects
higher volumes in each of the Company's divisions.  The sales increase is
partially offset by lower corn prices in 1997.  Corn is a key component in
Penford Products' paper chemical products, and changes in corn costs are
generally passed through to customers.  During 1997, corn prices generally
trended down from the historical highs of late fiscal 1996.  During 1997,
Penford Products increased shipments of corn-based products by 6.0%, reflecting
increased marketing efforts to certain key customers.  Penford Food Ingredients
volume increased by 31.0% primarily as a result of new customers for its french
fry coating products.  Penwest excipient sales were up slightly from 1996.

Gross margin was 25.7% in 1997 compared to 24.0% in 1996.  The increase
reflects higher volumes primarily at Penford Products and Penford Food
Ingredients, better corn pricing and the impact of manufacturing efficiencies
implemented during the year.

Operating expenses increased $2.1 million or 6.2%.  General and administrative
costs rose by $1.4 million primarily for company-wide information technology
support and to build the infrastructure to support anticipated growth for the
pharmaceuticals operations.  Research and development expenses increased
$700,000 or 10.4% , primarily due to increased spending at Penwest.  These
costs reflect an increased R&D headcount and greater expenditures for
bioequivalence studies in the drug formulation development area at Penwest
Pharmaceuticals.  Consolidated R&D expenditures will be reduced significantly
if the planned spin-off of Penwest is completed.

Other income of $1.2 million represents a gain on the sale of Southern
California air emission credits.

Interest expense increased $222,000 or 4.4%, primarily due to higher
outstanding debt balances.  The effective tax rate was 33.2% in fiscal 1997
compared to 32.5% in the prior year.  The effective rate is lower than the
statutory rate primarily due to tax credits and the effects of the Company's
foreign sales corporation.


Comparison of Fiscal 1996 to 1995 Results of Operations

Sales increased $20.3 million, or 11.7%, during fiscal 1996.  The increase in
sales reflected higher demand for the Company's core business.  The increase
was also due to unusually high corn costs, a key component used in pricing
Penford Products' paper chemical products.  Changes in corn costs are generally
passed through to customers.  During the year, Penford Products signed several
multi-year contracts to sell products to customers representing significant
volumes.  Penwest increased sales volumes for EMCOCEL(R) during fiscal 1996 by
17%.  This increase was primarily attributable to two new large customers.
Potato starch volumes at Penford Food Ingredients increased by 75% in 1996 due
to rapidly increasing demand for these starches for french fry coatings.

Gross margins were 24.1% in 1996 compared with 27.5% in 1995.  The decrease in
gross margin is primarily due to the historically high price of corn which
affected margins several ways.  First, certain of the Company's sales are based
on a recent average of published corn prices.  Consequently, in periods of
rapidly escalating prices, the Company is not able to recover the full amount
of the increase in raw material costs under such contracts.  Particularly in
the fourth quarter, the Company's margin on fixed
















                                    Page 15
<PAGE>   16

price sales contracts was also negatively impacted by the high price of cash
corn relative to the futures market driven by a severe supply/demand imbalance.
Due to the short supply of corn, the market cash price reflected a high premium
that had to be absorbed by the Company on its fixed price business.  Lastly,
lower margin dollars on higher unit sales prices also adversely impacted the
gross margin percentage.  The corn situation did improve in October as the new
crop was harvested.

In addition to the impact of corn, competitive and market factors put pressure
on product pricing in the renewal of customer sales contracts making it
difficult to maintain prior years gross margin levels.

Operating expenses increased $1.6 million, or 4.8%.  Research and development
(R&D) expenses increased $524,000, or 7.7%, as a result of greater development
spending at Penwest.

Other income in 1995 reflects a gain on the sale of assets of the Companys
subsidiary, Pacific Cogeneration, Inc. of $899,000.

Net interest expense remained consistent with the prior year.  The effective
tax rate was 32.5% in fiscal 1996, compared with 35.0% in fiscal 1995.  The
reduction in the tax rate reflects a reduction in state taxes and an increased
benefit from the Company's foreign sales corporation.

Liquidity and Capital Resources

The Company had working capital of $30.2 million at August 31, 1997.  The
Company has an unsecured $35 million credit agreement under which there was
$20.3 million outstanding at the end of fiscal 1997.  The Company also has $15
million of uncommitted lines with various banks that are used for overnight
borrowings.  These lines were used throughout the year, and there was $6.0
million outstanding at the end of fiscal 1997.

Operating cash flow was $20.2 million, $12.9 million and $16.3 million in
fiscal 1997, 1996 and 1995, respectively.

Subsequent to the proposed spin-off, Penford Corporation will retain all rights
and obligations under its various short and long-term borrowing arrangements,
including amounts available under the credit agreement and uncommitted lines.

Capital expenditures amounted to $21.5 million in fiscal 1997 compared to $21.5
million in fiscal 1996 and $23.0 million in fiscal 1995.  Capital expansion has
been funded from operating cash flows and borrowings under uncommitted lines.
Significant capital projects during fiscal 1997 included capacity expansion at
the Penford Food Ingredients' facility in Richland, Washington and the
completion a new corn unloading facility for Penford Products in Cedar Rapids,
Iowa.  The remainder of the expenditures were for various improvements to
manufacturing facilities.

Planned capital expenditures in fiscal 1998 will primarily be directed to
upgrades and modernization of certain Penford Products machinery and equipment
and the expansion of processing capabilities at Penford Food Ingredients.
Assuming completion of the proposed spin-off, capital expenditures in 1998
should be no greater than in fiscal 1997.  The Company expects to fund capital
expenditures from operating cash flows and from uncommitted lines of credit.

The Company commenced paying a quarterly cash dividend of $0.05 per share with
the quarter ended February 28, 1992, and has paid such dividend each quarter
thereafter.  The Board of Directors reviews the dividend policy on a periodic
basis.

In April 1994, the Board of Directors authorized a stock repurchase program for
the purchase of up to 500,000 shares of the outstanding common stock of the
Company.  The Company did not repurchase any of its common stock during fiscal
1997.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business

On October 9, 1997, Penford Corporation (formerly PENWEST, LTD.) announced a
plan to establish its pharmaceutical operations as a separate, publicly owned
company. In connection with the plan, PENWEST, LTD. changed its name to Penford
Corporation (See Note L).

Penford Corporation (Penford or the Company) is in the  business of developing,
manufacturing and marketing chemically modified carbohydrate-based specialty
chemicals.  The Company operates in three market lines:  carbohydrate-based
specialty chemicals used in paper manufacturing, pharmaceutical excipients and
controlled release technology, and food ingredient products.  Customers are
primarily manufacturers in the paper industry, makers of prescription
pharmaceuticals, over-the-counter drugs and vitamins, and processors in the food
industry. Sales of the Company's products are generated using a combination of
direct sales and distributor agreements.

Basis of Presentation

The consolidated financial statements include Penford and its wholly-owned
subsidiaries.  Material intercompany balances and transactions have been
eliminated.  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements
and accompanying notes.  Actual results could differ from those estimates.

Certain amounts in the financial statements for prior years have been
reclassified to conform with the current year presentation.  These
reclassifications had no effect on previously reported results of operations.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of less
than three months when purchased to be cash equivalents.

Cash equivalents consist of money market funds, short-term deposits, and
commercial paper.  Amounts reported in the balance sheets represent cost which
approximates market value.

Penford's cash management system includes a cash overdraft feature for
uncleared checks in the disbursing accounts.  Cash in the accompanying balance
sheets represents the net amounts available to the disbursing accounts.
Uncleared checks of $1,446,000 and $2,177,000 are netted against cash at August
31, 1997 and 1996, respectively.






                                    Page 23
<PAGE>   24
Concentration of Credit Risk and Financial Instruments

The Company performs ongoing credit evaluations of its customers and generally
does not require collateral.  The Company maintains an allowance for doubtful
accounts which management believes is sufficient to cover potential credit
losses.  The carrying value of financial instruments including cash,
receivables, and payables approximates market value at August 31, 1997.  The
fair market value of long-term debt is approximately $69.9 million at 
August 31, 1997 with a carrying value of $67.7 million.  The carrying value of 
long-term debt approximated market value at August 31, 1996.  The fair value of
fixed rate, long-term debt is estimated using discounted cash flow analyses, 
based on the Company's current incremental borrowing rates for similar types 
of borrowings.

Penford Products' two largest customers individually accounted for
approximately 15% and 10% of sales in fiscal 1997 and one customer represented
approximately 14% of sales in fiscal 1996.  No customers accounted for greater
than 10% of total sales in years prior to 1996.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost.  Expenditures for
maintenance and repairs are expensed as incurred.  The Company uses the
straight-line method to compute depreciation assuming average useful lives of
three to forty years for financial reporting purposes.  For income tax
purposes, the Company generally uses accelerated depreciation methods.

Interest is capitalized on major construction projects while in progress.
Interest of $724,000, $300,000 and $209,000 was capitalized in 1997,1996 and
1995, respectively.

Foreign Currencies

Monetary assets and liabilities of the Company's foreign operations are
translated into U.S. dollars at year-end exchange rates and revenue and
expenses are translated at average exchange rates.  Non-monetary assets and
liabilities are converted at historical rates.  In each instance, the
functional currency is the local currency.  Realized gains and losses from
foreign currency transactions are included in the statements of income.

Income Taxes

The provision for income taxes includes federal and state taxes currently
payable and deferred income taxes arising from temporary differences between
financial and income tax reporting methods.  Deferred taxes have been recorded
using the liability method in recognition of these temporary differences.

Revenue Recognition

Sales revenue is recorded upon shipment of product.

Research and Development

Research and development costs of $8,057,000, $7,297,000 and $6,773,000 in
1997, 1996 and 1995, respectively, were charged to expense as incurred.

Earnings Per Common Share

Earnings per common share were computed by dividing net income by the weighted
average number of common shares and dilutive common share equivalents
outstanding during the fiscal year.  Outstanding stock options and stock
appreciation rights are considered to be common share equivalents.

In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 128, Earnings per Share, which is required to be adopted in the
second quarter of fiscal 1998.  At that time, the Company will be required to
change the method currently used to compute earnings per share and to restate
all prior periods.  Under the new requirements for calculating primary earnings
per share, the dilutive effect of stock options will be excluded.  The impact
is expected to result in increases of $0.02 , $0.02 and $0.04 to primary
earnings per share for the fiscal years ended August 31, 1997, 1996 and 1995,
respectively.  The impact of Statement 128 on the calculation of fully diluted
earnings per share is not expected to be material.

Stock Compensation

In October 1995, the FASB issued Statement No. 123, "Accounting for Stock-Based
Compensation."  The Statement is effective for fiscal years beginning after
December 15, 1995 and requires stock-based compensation expense to be measured
using either the intrinsic-value method as prescribed by Accounting Principles
Board ("APB") No. 25 or the fair-value method described in Statement No. 123.
The Company has adopted Statement  No. 123 in fiscal 1997 using the
intrinsic-value method, which has no effect on the Company's financial position
or results of operations (see Note E).

Recent Accounting Standards

The FASB has recently issued Statement No. 130 on Comprehensive Income and
Statement No. 131 regarding disclosures of Business Segment Information.  The
aforementioned standards will require additional financial statement disclosure
for all periods presented, but will not impact the Company's reported financial
position or results of operations.  The new standards will be adopted in fiscal
1999.

NOTE B
INVENTORIES

Inventories are stated at the lower of cost or market.  Cost, which includes
material, labor and manufacturing overhead costs, is determined by the
first-in, first-out (FIFO) method.

The Company generally follows a policy of hedging corn purchases related to
fixed price sales contracts and certain anticipated corn purchases to minimize
price risk due to market fluctuations and risk of crop failure.  The
instruments used are principally readily marketable exchange traded futures
contracts which are designated as hedges.  The changes in market value of such
contracts have a high correlation to the price changes of the hedged commodity.
Also, the underlying commodity can be delivered against such contracts.  Gains
or losses arising from open and closed hedging transactions are included in
inventory as a cost of raw materials and reflected in the statements of income
when the product is sold.

Components of inventory are as follows:

The unsecured credit agreement is a $35 million facility involving four banks.
There was $20.3 million outstanding at fiscal year end, and borrowings mature
on December 30, 1999.  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 unsecured credit agreement, the private placements, and other notes
include, among other terms, various limitations on long-term indebtedness,
minimum net worth and working capital ratios, and restrictions on Penford's
ability to purchase or redeem its own stock.  The unsecured credit agreement
also requires the Company to maintain a minimum fixed charge coverage ratio.

The Company has uncommitted lines of credit aggregating $15 million, which
provide for financing at various floating rates of which $6.0 million was
outstanding at August 31, 1997.





                                    Page 27

The Company enters into interest rate swap agreements to modify the interest
characteristics of its outstanding debt.  These agreements involve the exchange
of interest payment streams without an exchange of the underlying principal
amount.  Net amounts paid or received are reflected as adjustments to interest
expense.  The fair values of the swap agreements are not recognized in the
financial statements.  In the event of default by a counterparty, the risk in
these transactions is the cost of replacing the interest rate contract at
current market rates.  Management continually monitors the credit ratings of
its counterparties, and believes the risk of incurring such losses is remote,
and that if incurred, such losses would be immaterial.  At August 31, 1997,
approximately $25 million of the Company's outstanding debt was subject to
interest rate swap agreements.  Of this amount, $15 million involves floating
rate to fixed rate swaps which effectively fix rates at approximately 9.0% and
$10 million involves fixed rate to floating rate swaps, with the floating rate
approximating 6.3% at August 31, 1997.

The Company has hedged the interest rate risk on $8.9 million of its long-term
debt using Treasury note futures.  The cost of the hedge has been deferred and
will be recognized as a component of interest expense over the life of the
debt.  The hedge results in an effective interest rate on the related long-term
debt of approximately 9.5%.

NOTE D
LEASES

Certain of the Company's property, plant, and equipment is leased under
operating leases ranging from one to fifteen years with renewal options.
Rental expense under operating leases was $4,418,000, $4,482,000 and $3,202,000
for fiscal years ended August 31, 1997, 1996 and 1995, respectively.  Future
minimum lease payments as of August 31, 1997 for noncancellable operating
leases having initial lease terms of more than one year are as follows

NOTE E:
STOCK OPTIONS


The Company has two stock option plans for which 1,500,000 shares of Common
Stock have been authorized for grants of options:  the 1994 Stock Option Plan
(the "1994 Plan") and the Stock Option Plan for Non-Employee Directors (the
"Directors' Plan").  The 1994 Plan replaced the 1984 Stock Option Plan (143,000
shares outstanding at August 31, 1997) which expired in February 1994, and
provides for the granting of stock options at the fair market value of the
Company's Common Stock on the date of grant.  Either incentive stock options or
non-qualified stock options are granted under the 1994 Plan.  The incentive
stock options generally vest over five years at the rate of 20% each year and
expire 10 years from the date of grant.  The non-qualified stock options
generally vest over four years at the rate of 25% of each year and expire 10
years and 10 days from the date of grant.

The Directors' Plan provides for the granting of non-qualified stock options at
75% of the fair market value of the Company's Common Stock on the date of grant
for annual retainers and meeting fees in lieu of cash compensation at each
Director's annual election.  Options granted under the Directors' Plan vest six
months after the grant date and expire at the earlier of ten years after the
date of grant or three years after the date the non-employee director ceases to
be a member of the Board.  In addition, non-employee directors receive
restricted stock under a restricted stock plan every three years.  The
restricted stock may be sold or otherwise transferred at  the rate of 33.3%
each year.

Effective September 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation," using
the intrinsic-value method prescribed by APB Opinion No. 25, as allowed for in
the Statement.  Accordingly, no compensation expense has been recognized for
the stock-based compensation plans other than for the Directors' Plan and
restricted stock awards.  Had compensation cost been recognized based on the
fair value at the date of grant for options awarded in 1997 and 1996 under the
Plans, pro forma amounts of the Company's net income and net income per share
would have been as follows:

            Net income per share, primary - pro forma        $     0.80      $    0.67
</TABLE>


The fair value of each option grant was estimated using the Black-Scholes
option-pricing model with the following weighted average assumptions: risk-free
interest rates of 5.6% to 6.1%; expected option life of each vesting increment
of 2.8 years for employees and 3.0 years for non- employee directors; expected
volatility of 49%; and expected dividends of $0.20 per share.  The weighted
average fair value of options granted under the 1994 Plan during fiscal years
1997 and 1996 was $9.46 and $10.57, respectively.  The weighted average fair
value of options granted under the Directors' Plan during fiscal years 1997 and
1996 was $9.29 and $11.66, respectively.  The effect of applying Statement No.
123 for providing pro forma disclosures for fiscal years 1997 and 1996 is not
likely to be representative of the effects in future years





                                    Page 29

because the amounts above reflect only the options granted in 1997 and 1996
that vest over four to five years, and additional grants are made annually.

NOTE G
PENSION AND OTHER EMPLOYEE BENEFITS

Penford maintains two noncontributory defined benefit pension plans that cover
substantially all employees.

Benefits under the plan for hourly employees are primarily related to years of
service.  Benefits for salaried employees are primarily related to years of
credited service and final average five-year earnings.  Employees generally
become eligible to participate in the plans after attaining age 21 and benefits
normally become vested after five years of credited service.

The Company's funding policy is to contribute amounts to the plans sufficient
to meet or exceed the minimum requirements of the Employee Retirement Income
Security Act of 1974.

Assumptions used in the measurement of the projected benefit obligation
included a discount rate of 7.5% in 1997 and 8.0% in 1996, and a rate of
increase in compensation levels of 4.0% in 1997 and 5.0% in 1996 for the
salaried employees.  The expected long-term rate of return on plan assets is
assumed to be 10.0% for 1997 and 9.0% for 1996 and 1995.  Changes in the
assumptions used in the measurement of the projected benefit obligation had the
effect of reducing pension expense by $268,000 in 1997.

Net periodic pension expense consisted of the following (in thousands):

Savings And Stock Ownership Plan

The Company has a savings investment plan.  The savings component, available to
all employees, matches 75% of the employee's contribution up to 6% of the
employee's pay, in the form of Penford common stock.  During 1997,
approximately 54,435 shares of stock were earned by plan participants.  The
savings component expense of the plan was $877,000, $722,000 and $520,000 for
fiscal years 1997, 1996 and 1995, respectively.  Compensation expense is
recorded by the Company at the market value of shares contributed to the Plan.

The plan also includes an annual profit-sharing component that is awarded by
the Board of Directors based on achievement of predetermined corporate goals.
This feature of the plan is available to all employees who meet the eligibility
requirements of the plan.  The profit-sharing expense, which reflects the
market value of shares released by the plan to participants was $212,000,
$514,000 and $402,000 for the fiscal years 1997, 1996 and 1995, respectively.

The plan initially acquired the Penford common stock by issuing a note to the
Company.  The note is reflected as a reduction of shareholders' equity and is
amortized ratably over the note term which expires in December 1999.  The
shares held by the plan are considered outstanding for purposes of calculating
earnings per share.  Dividends on shares held by the plan are allocated to
participant accounts.

Supplemental Executive Retirement Plan

The Company sponsors a Supplemental Executive Retirement Plan (SERP), a
non-qualified plan, which covers certain employees.  For 1997, 1996 and 1995,
the net pension expense accrued for the SERP was $622,000, $950,000 and
$856,000 respectively.

Health Care And Life Insurance Benefits

The Company offers health care and life insurance benefits to most active
employees.  Costs incurred to provide these benefits are charged to expense
when paid.  Health care and life insurance expense was $2,778,000, $2,632,000
and $2,501,000 in 1997, 1996 and 1995, respectively.

NOTE H
OTHER POSTRETIREMENT BENEFITS

Penford maintains two postretirement benefit plans that cover substantially all
salaried and hourly retirees.

Benefits under the plan for hourly employees include medical coverage,
prescription drug coverage, and, to a certain grandfathered group, life
insurance.  Hourly participants contribute to the cost of the benefits based on
a pension credit formula.  Benefits under the plan for salaried employees
include medical coverage and vision coverage.  Salaried participants
contribute, for the most part, 100% of the premiums.  Presently the Company
funds the current benefits on a cash basis and therefore there are no plan
assets.

Future benefit costs were estimated assuming medical costs would increase at a
9.5% annual rate for fiscal 1997, decreasing by one half of a percent ratably
over the next eight years to a rate of 5.5%.  A 1% increase in this annual
trend rate would have increased the accumulated postretirement benefit
obligation at August 31, 1997 by $1.1 million, with an increase of $128,000 in
the annual 1997 postretirement benefit expense.  The weighted average discount
rate used to estimate the accumulated postretirement obligation was 7.5% and
8.0% in 1997 and 1996, respectively.  The change in discount rate had the
impact of decreasing the accumulated postretirement benefit obligation by
$343,000.

SHAREHOLDERS' EQUITY

Unissued Preferred Stock

There are 1,000,000 shares of $1.00 par value preferred stock authorized for
issue; however, none are outstanding.

Common Stock Purchase Rights

On June 16, 1988, Penford distributed a dividend of one right (Right) for each
outstanding share of Penford common stock.  In May 1997 the Company amended its
Shareholder Rights Plan.  When exercisable, each Right will entitle its holder
to buy one share of Penford's common stock at $100 per share.  The Rights will
become exercisable if a purchaser acquires 15% of Penford's common stock or
makes an offer to acquire common stock.  In the event that a purchaser acquires
15% of the common stock of Penford, each Right shall entitle the holder, other
than the acquirer, to purchase one share of common stock of Penford for one
half of the market price of the common stock.  In the event that Penford is
acquired in a merger or transfers 50% or more of its assets or earnings to any
one entity, each Right entitles the holder to purchase common stock of the
surviving or purchasing company having a market value of twice the exercise
price of the Right.  The Rights may be redeemed by Penford at a price of $0.01
per Right, and expire in June 2008.

NOTE L
SUBSEQUENT EVENT

On October 9, 1997, Penford announced a two stage plan designed to foster the
growth potential of its pharmaceuticals business and separately, its paper and
food ingredients businesses.  Under the first stage of the plan, Penwest
Pharmaceuticals Co. (Penwest) would sell up to 20% of its common stock through
an initial public offering.  Under the second stage of the plan, Penford would
effect a tax-free spin-off to its shareholders of its remaining ownership of
Penwest common shares, contingent upon satisfying certain conditions, including
receipt of a tax ruling from the Internal Revenue Service or a written opinion
from Ernst & Young LLP to the effect that, among other things, the spin-off will
qualify as a tax-free distribution.  The spin-off is anticipated to occur in the
second quarter of calendar 1998.  If the spin-off occurs, Penwest will no longer
be a subsidiary of Penford.

On October 21, 1997, Penwest filed a registration statement with the Securities
and Exchange Commission for an initial public offering of 2,500,000 shares of
common stock (approximately 15% of its outstanding common stock).  The estimated
initial public offering price is between $10.00 to $12.00 per share.  An option
will be granted to the underwriters to purchase up to 375,000 additional shares
for the purpose of covering over-allotments, if any.  Penford and Penwest have
entered into a Separation Agreement setting forth the agreement of the parties
with respect to the principal corporate transactions required to effect the
separation of Penford's pharmaceutical business from its paper and food
ingredients businesses, the initial public offering and the spin-off, and
certain other agreements governing the relationship of the parties prior to and
after the spin-off.  Penford and Penwest will, prior to the completion of the
initial public offering, also enter into other agreements that govern various
interim and ongoing relationships.

Penwest will retain the proceeds from the planned initial public offering.  In
addition, Penford will forgive all intercompany advances as of the closing of
the offering.  As of August 31, 1997, the intercompany balance approximated
$35.2 million.  Had the proposed plan been effected as of August 31, 1997, it is
estimated that consolidated assets and shareholders' equity of Penford would
have reflected a reduction of approximately $35.0 to $40.0 million, representing
the net effects of the proposed distribution.

Summarized financial data of Penwest is as follows:

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



The Board of Directors and Shareholders
Penford Corporation.


We have audited the accompanying consolidated balance sheets of Penford
Corporation (formerly PENWEST, LTD.) as of August 31, 1997 and 1996, and the
related consolidated statements of income, shareholders' equity, and cash flows
for each of the three years in the period ended August 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Penford
Corporation (formerly PENWEST, LTD.) at August 31, 1997 and 1996, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended August 31, 1997, in conformity with generally accepted
accounting principles.

               1.1    Stock Certificates

               Stock certificates of the Corporation shall be in such form as
the Board of Directors may from time to time prescribe. Every stock certificate
shall be signed by two officers designated by the Board of Directors and sealed
with the corporate seal. All certificates shall be countersigned by a transfer
agent and a registrar of the Corporation. Any and all signatures on any such
certificate and the corporate seal upon any such certificate may be a facsimile.
In case any officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent, or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he or she were such

               The shares of stock of the Corporation shall be transferable on

thereof in person or by such holder's duly authorized attorney upon surrender
and cancellation of such holder's certificates, properly endorsed, accompanied
by authority to transfer. Upon surrender, as above provided, of a stock
certificate, one or more new stock certificates for such aggregate number of
shares of stock as equals the aggregate number of shares represented by the
surrendered stock certificate shall be issued to the parties entitled thereto.

               1.3    Holders of Stock of Record

               The Corporation shall be entitled to treat the holder of record
of any share or shares of stock of the Corporation as the holder in fact
thereof, and shall not be bound to recognize any claim to, or interest in, such
shares on the part of any other person, whether or not the Corporation shall
have express or other notice thereof.

               The Board of Directors of the Corporation shall have the power
and authority to make all such rules and regulations as the Board may deem
proper or expedient concerning the issue, transfer, and registration of stock
certificates for shares of stock of the Corporation. The Board of Directors
shall have the power and authority to appoint from time to time one, or more
than one, transfer agent, and one, or more than one, registrar of transfers, and
may require all stock certificates for shares of stock of the Corporation to be
properly countersigned, and/or otherwise properly authenticated, by such
transfer agent or registrar.

               1.5    Rules and Regulations Concerning Lost and Destroyed 
Certificate

               A new certificate or certificates of stock may be issued in place
of any certificate or certificates of stock theretofore issued by the
Corporation and alleged to have been lost or destroyed, upon delivery to the
Secretary of the Corporation or any authorized transfer agent of the Corporation
of a written claim in the form of an affidavit stating all pertinent facts
relating to the alleged loss or destruction of such certificate or certificates
together with an open penalty indemnity bond, approved as provided below,
written by a surety company approved by an executive officer of the Corporation
and indemnifying against any claim that may be made against the Corporation for
or in respect of the shares of stock represented by the certificate or
certificates alleged to have been lost or destroyed. The penalty of such bond
shall be unlimited as to time and amount and such bond must be approved by an
executive officer of the Corporation. The Board of Directors may, in the
discretion of a majority of the Board, however, direct the issuance of a
certificate or certificates in place of any certificate or certificates alleged
to have been lost or destroyed upon such lesser conditions or security.

for Voting and For Other Purposes

               At least 10 days before each meeting of shareholders, an
alphabetical list of the shareholders entitled to notice of such meeting shall
be made, arranged by voting group and by each class or series of shares therein,
with the address of and number of shares held by each shareholder. This record
shall be kept at the principal office of the Corporation for 10 days prior to
such meeting, and shall be kept open at such meeting, for the inspection of any
shareholder or any shareholder's agent.

               For the purpose of determining shareholders entitled to (a)
notice of or to vote at any meeting of shareholders or any adjournment thereof,
or (b) to receive payment of any dividend, or in order to make a determination
of shareholders for any other purpose, the Board of Directors may fix a future
date as the record date for any such determination. Such record date shall be
not more than 70 days, and in case of a meeting of shareholders not less than 10
days, prior to the date on which the particular action requiring such
determination is to be taken. If no record date is fixed for the determination
of shareholders entitled to notice of or to vote at a meeting, the record date
shall be the day immediately preceding the date on which notice of the meeting
is first given to shareholders. Such a determination shall apply to any
adjournment of the meeting unless the Board of Directors fixes a new record
date, which it shall do if the meeting is adjourned to a date more than 120 days
after the date fixed for the original meeting. If no record date is set for the
determination of shareholders entitled to receive payment of any stock dividend
or distribution (other than one involving a purchase, redemption, or other
acquisition of the Corporation's shares), the record date shall be the date the
Board of Directors authorizes the stock dividend or distribution.

               2.7    Officers of Meetings of Shareholders

               The President of the Corporation (or in his or her absence, the
Chairman of the Board of Directors of the Corporation) may call any meeting of
shareholders to order and shall be the Chairman thereof. If the Chairman of the
Board of Directors and the President are absent from any such meeting, then a
Vice President of the Corporation shall be the Chairman thereof and shall
preside at such meeting. The Secretary of the Corporation, if present at any
meeting of its shareholders, shall act as the Secretary of such meeting. If the
Secretary is absent from any such meeting, the Chairman of such meeting may
appoint a Secretary for the meeting.

               2.8    Proper Business for Shareholders' Meetings

               At any annual or special meeting of the shareholders of the
Corporation, only business properly brought before the meeting may be
transacted. To be properly brought before an annual or special meeting, business
or other proposals must be (i) specified in the notice of the meeting (or any
supplement thereto) given by or at the direction of the Board of Directors, (ii)
otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (iii) otherwise properly brought before the meeting by a
shareholder. For business to be properly 


                                      -4-
<PAGE>   5

brought before an annual meeting by a shareholder, written notice thereof must
have been received by the Secretary of the Corporation from such shareholder not
less than 120 days prior to the date corresponding to the date on which the
Corporation mailed its proxy statement in connection with its previous year's
annual meeting of shareholders. For business to be properly brought before a
special meeting by a shareholder, or in the event the date of the annual meeting
has been changed by more than 30 calendar days from the date contemplated at the
time of the previous year's proxy statement, notice by the shareholder to be
timely must be received by the Secretary of the Corporation not later than the
close of business on the 10th day following the earlier of the day on which
notice of the date of the scheduled meeting was mailed or the day on which
public disclosure of such date was made.

               Any such notice shall set forth as to each matter the shareholder
proposes to bring before the meeting (i) a brief description of the business
desired to be brought before the meeting, the reasons for conducting such
business at the meeting, and the language of the proposal, (ii) the name and
address of the shareholder proposing such business, (iii) a representation that
the shareholder is a holder of record of stock of the Corporation entitled to
vote at such meeting, and (iv) any material interest of the shareholder in such
business. Any such notice to the Corporation shall also comply with all
applicable provisions of Regulation 14A under the Securities Exchange Act of
1934. No business shall be conducted at any meeting of shareholders except in
accordance with this Section, and the Chairman of any meeting of shareholders
and the Board of Directors may refuse to permit any business to be brought
before the meeting without compliance with the foregoing procedures.

                                   ARTICLE III

               3.1    Number of Directors

               The authorized number of directors of the Corporation shall be
not less than seven, nor more than fifteen. The Board of Directors, by
resolution, shall fix the number of directors to constitute the whole Board of
Directors of the Corporation, within the above limits, which number shall
prevail until a resolution is adopted by the Board of Directors prescribing a
different number of directors to be the authorized number of directors of the
Corporation.

               3.2    Qualifications of Directors

               Directors need not be shareholders of the Corporation or
residents of the State of Washington. Each director of the Corporation shall be
eligible to serve as a director until the annual meeting of shareholders
immediately following such director's 72nd birthday.

               3.3    Election of Directors -- Terms of Office

               The shareholders shall, at their annual meeting held each year,

               3.4    Nominations of Directors for Election

               Nominations for the election of directors may be made by the
Board of Directors or a committee appointed by the Board of Directors or, if the
shareholders are, at the time, entitled to cumulate their votes in the election
of directors in accordance with Article IX of the Articles of Incorporation of
the Corporation, by a majority of the "Disinterested Directors" or by any
shareholder who is the "Beneficial Owner" of one percent or more of the
outstanding shares of "voting stock" of the Corporation as said terms are
defined in the Articles of Incorporation in accordance with the following
procedures. However, any such one percent shareholder at the time may nominate
one or more persons for election as directors at a meeting only if written
notice of such shareholder's intent to make such nomination or nominations has
been given, either by personal delivery or by United States mail, postage
prepaid, to the Secretary of the Corporation in accordance with the following
procedures: For a nomination to be properly submitted before an annual meeting
by a shareholder, written notice thereof must have been received by the
Secretary of the Corporation from such shareholder not less than 120 days prior
to the date corresponding to the date on which the Corporation mailed its proxy
statement in connection with its previous year's annual meeting of shareholders.
For a nomination to be properly submitted before a special meeting by a
shareholder, or in the event the date of the annual meeting has been changed by
more than 30 calendar days from the date contemplated at the time of the
previous year's proxy statement, notice by the shareholder to be timely must be
received by the Secretary of the Corporation not later than the close of
business on the 10th day following the earlier of the day on which notice of the
date of the scheduled meeting was mailed or the day on which public disclosure
of such date was made.

               Each such notice to the Secretary shall set forth: (i) the name
and address of record of the shareholder who intends to make the nomination;
(ii) a representation that the shareholder is a holder of record of shares of
the Corporation entitled to vote at such meeting and intends to appear in person
or by proxy at the meeting to nominate the person or persons specified in the
notice; (iii) the name, age, business and residence addresses, and principal
occupation or employment of each nominee; (iv) a description of all arrangements
or understandings between the shareholder and each nominee and any other person
or persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by the shareholder; (v) such other information
regarding each nominee proposed by such shareholder as would be required to be
included in a proxy statement filed pursuant to the proxy rules of the
Securities and Exchange Commission; and (vi) the consent of each nominee to
serve as a director of the Corporation if so elected. The Corporation may
require any proposed nominee to furnish such other information as may reasonably
be required by the Corporation to determine the eligibility of such proposed
nominee to serve as a director of the Corporation. The presiding officer of the
meeting may, if the facts warrant, determine that a nomination was not made in
accordance with the foregoing procedure, and if such officer should so
determine, such officer shall so declare to the meeting and the defective
nomination shall be disregarded.

               3.5    Failure to Elect Directors at Annual Meeting of the 
Shareholders

               If the class of directors of the Corporation to be elected at the
annual meeting shall not be elected as herein provided at the annual meeting in
any year of the shareholders of the Corporation, or at any adjournment of such
annual meeting, then, in such event, the Corporation shall not for that reason
be dissolved, but its directors at the time shall be deemed lawful directors of
the Corporation for all purposes, and shall continue to hold office as directors
until their successors, respectively, are duly elected and qualified.

               3.6    Authority of the Board of Directors

               The business of the Corporation shall be managed by its Board of
Directors, and such Board shall have and exercise full powers and authority in
the management, control, regulation, and conduct of the property, interests,
business transactions and affairs of the Corporation; provided, however, that
the Executive Committee of the Board of Directors of the Corporation may
exercise the power and authority of such Board pursuant but subject to (a) the
limitations in Section 23B.08.250 of the Washington Business Corporation Act and
(b) restrictions imposed by the Board of Directors pursuant to Article IV
hereof. If the position, Chairman of the Board, is not designated as an office
of the Corporation, then the Board may from time to time elect one of its
members to act as Chairman.

               3.7    Action by the Board of Directors or Any of Its Committees
Without a Meeting

               Any action required or permitted to be taken at any meeting of
the Board of Directors or of the Executive Committee or of any other committee
of said Board may be taken without a meeting if a written consent describing the
action taken is signed by all members of the Board or of such committee, as the
case may be, and such written consent is filed with the minutes of said Board or
of said committee. Action taken by such written consent is effective when the
last director signs the consent, unless the consent specifies a later effective
date.

               3.8    Regular Meetings of the Board of Directors

               Meetings of the Board of Directors of the Corporation may be held
at its corporate offices, or at such other place or places as may be authorized
by such Board. Such Board shall also fix the time or times of such regular
meetings. No notice of any regularly scheduled meeting need be given. The
Chairman of the Board or the President may change the time and place of any
regular meeting by giving reasonable notice thereof, in writing or by telephone,
not later than 24 hours before the time originally fixed for such meeting. The
Chairman of the Board shall act as Chairman of the meetings, but in his or her
absence, the President shall act as Chairman. The Secretary of the Corporation
shall act as Secretary of the meetings, but in his or her absence, the Chairman
of the meeting shall appoint a Secretary of the meeting.

               3.9    Special Meetings of the Board of Directors

               Meetings of the Board of Directors of the Corporation may be held
from time to time on written call thereof by the Chairman of the Board of
Directors or the President made at any time at his or her own instance and
discretion or on call thereof made by such number of its directors as equals a
majority of its whole Board of Directors at the time. Any special meeting of the
Board of Directors may be held at such time or at such place designated in said
call. The time, place, and purpose of any special meeting of the Board of
Directors to be held pursuant to call and notice shall be stated both in the
call and the notice thereof, and no business other than that stated in such
notice shall be transacted, or acted upon, at such special meeting. Reasonable
notice of a special meeting shall be given in writing or by telephone by the
person or persons calling the meeting, not later than 72 hours prior to the time
set for the meeting; provided that the minimum notice period shall be 48 hours
in the event of a tender or exchange offer to purchase securities of the
Corporation. Any special meeting of the Board of Directors may be held at any
time without previous call, or previous notice thereof, if all directors of the
Corporation either attend such meeting, or consent in writing thereto, or if
each director not present at such meeting waives notice thereof. Any and all
business and matters pertaining to the affairs of the Corporation may be
considered, transacted, and acted on at any special meeting so held without
previous call or previous notice.

               3.10   Quorum of Directors

               A majority of the members of the Board of Directors as
constituted for the time being shall constitute a quorum for the transaction of
business, but less than a quorum may adjourn any meeting from time to time until
a quorum is present and without further notice being given.

               3.11   Waiver of Notice of Meetings of the Board of Directors

               Any director of the Corporation may waive in writing at any time
any such notice of any meeting of the Board of Directors of the Corporation as
may be provided by the Washington Business Corporation Act or by these Bylaws to
be given; and a written waiver thereof signed by any director entitled to such
notice, whether before or after the time stated therein, shall be deemed
equivalent to such notice legally given to such director. Attendance at any
meeting of the Board of Directors of the Corporation by a director shall
constitute waiver of notice of such meeting, unless such director at the
beginning of the meeting, or promptly upon such director's arrival, objects to
holding the meeting or transacting business thereat and does not thereafter vote
for or assent to action taken at the meeting.

               3.12   Fees to the Directors for Attending Meetings of the Board 
of Directors

               The directors of the Corporation shall be entitled, as directors,
to receive an annual fee for service as directors and an attendance fee for

of Directors. Said fees shall be payable in the

amounts and under provisions prescribed from time to time by resolution of the
Board of Directors, and the Corporation is hereby authorized to pay such fees to
each of its directors; provided, however, that no director of the Corporation
shall be entitled to said fee if at the time he or she is otherwise employed by
the Corporation at a regular monthly or annual salary as a full time employee.

               3.13   Meeting by Telephone

               Members of the Board of Directors or any committee designated by
these Bylaws or appointed by the Board of Directors may participate in a meeting
of such Board or committee by means of a conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other at the same time, and participation by such means
shall constitute presence at a meeting.

own members. Each committee must have two or more members, who shall serve at
the pleasure of the Board of Directors.

               4.2    Authority of Committees

               Each committee shall have and may exercise the authority of the

period of time as the Board may fix in such resolution.

               5.2    Qualifications of Officers

Penford to distribute to shareholders of Penford the outstanding shares of

         WHEREAS, Penford and Penwest have further determined that it is
necessary and desirable to set forth the principal corporate transactions

              (b)  Subject to Section 4.4 hereof, each holder of Penford Common
Stock on the Record Date (or such holder's designated transferee or transferees)
shall be entitled to receive, in the Distribution, a number of shares of Penwest
Common Stock equal to the number of outstanding shares of Penwest Common Stock
owned by Penford on the Record Date multiplied by a fraction, the numerator of
which is the number of shares of Penford Common Stock held by such holder on the
Record Date, and the denominator of which is the number of shares of Penford
Common Stock outstanding on the Record Date.

              (c)  Penwest and Penford, as the case may be, will provide to the
Agent all share certificates and any information required in order to complete
the Distribution on the basis specified above.

         4.2  ACTIONS PRIOR TO THE DISTRIBUTION.

<PAGE>   14



concerning Penwest, its business, operations and management, the Distribution
and such other matters as Penford and Penwest shall reasonably determine and as
may be required by law. Penford and Penwest, as may be appropriate, will prepare
and to the extent required under applicable law, will file with the Commission
any such documentation which Penford determines are necessary or desirable to
effectuate the Distribution and Penford and Penwest shall each use its
reasonable best efforts to obtain all necessary approvals from the Commission
with respect thereto.

              (b)  In addition to their respective obligations under Section
4.2(a) above, Penford and Penwest shall take all other actions as may be
necessary or appropriate under the securities or blue sky laws of the United
States in connection with the Distribution.

              (c)  Penford and Penwest shall use their reasonable best efforts
to cause the conditions set forth in Section 4.3 to be satisfied and to effect
the Distribution on the Distribution Date.

              (d)  Penwest shall prepare and file, and shall use its reasonable
best efforts to have approved, an application for the listing of the Penwest
Common Stock to be distributed in the Distribution on the Nasdaq National
Market.

         4.3  CONDITIONS TO DISTRIBUTION. Penford shall have the sole discretion
to determine the date of consummation of the Distribution at any time prior to
the date six months after the Closing Date. Following the date six months after
the Closing Date, Penford shall be obligated to effect the Distribution as
promptly as practicable, subject to the satisfaction, or waiver by the Penford
Board of Directors in its sole discretion, of the conditions set forth below.

              (a)  A private letter ruling from the Internal Revenue Service 
(the "Private Letter Ruling") shall have been obtained, and shall continue in
effect, or a written opinion from Ernst & Young LLP shall have been delivered,
in either case to the effect that, among other things, the Distribution will
qualify as a tax-free distribution for federal income tax purposes under
Sections 355 and 368 of the Code, and such ruling or opinion shall be in form
and substance satisfactory to Penford in its sole discretion.

              (b)  Any material Governmental Approvals and consents necessary to
consummate the Distribution shall have been obtained and shall be in full force
and effect.

              (c)  No order, injunction or decree issued by any court or agency
of competent jurisdiction or other legal restraint or prohibition preventing the
consummation of the Distribution shall be in effect and no other event outside
the

                                      -14-

<PAGE>   15



control of Penford shall have occurred or failed to occur that prevents the
consummation of the Distribution.

              (d)  The transactions contemplated hereby shall be in compliance
with applicable federal and state securities laws.

              (e)  Each of Penwest and Penford shall have received such
consents, and shall have received executed copies of such agreements or
amendments of agreements, as they shall deem necessary in connection with the
completion of the transactions contemplated by this Agreement or any other
agreement or document contemplated by this Agreement or otherwise.

              (f)  All action and other documents and instruments deemed
necessary or advisable in connection with the transactions contemplated hereby
shall have been taken or executed, as the case may be, in form and substance
satisfactory to Penford and Penwest.

              (g)  No material adverse change shall have occurred with respect
to the business or financial condition of Penford since August 31, 1997, or
Penwest since September 30, 1997, which would, in the reasonable judgment of the
Penford Board of Directors, make approval of the Distribution inadvisable.

The foregoing conditions are for the sole benefit of Penford and shall not give
rise to or create any duty on the part of Penford or the Penford Board of
Directors to waive or not waive any such condition.

         4.4  FRACTIONAL SHARES. As soon as practicable after the Distribution
Date, Penford shall direct the Agent to determine the number of whole shares and
fractional shares of Penwest Common Stock allocable to each holder of record of
Penford Common Stock as of the Record Date, to aggregate all such fractional
shares and sell the whole shares obtained thereby in open-market transactions in
the Agent's sole discretion as to when, how, through which broker-dealer and at
what price to make such sales, and to cause to be distributed to each such
holder or for the benefit of each such holder, in lieu of any fractional share,
such holder's ratable share of the proceeds of such sale, after making
appropriate deductions of the amount required to be withheld for federal income
tax purposes and after deducting an amount equal to all brokerage charges,
commissions and transfer taxes attributed to such sale. Penford and the Agent
shall use their reasonable best efforts to aggregate the shares of Penford
Common Stock that may be held by any holder of record thereof through more than
one account in determining the fractional share allocable to such holder.

Washington, with requisite corporate power to own their properties and assets
and to carry on their respective businesses as presently conducted or
contemplated.

                                   ARTICLE VI

                  MISCELLANEOUS LIABILITIES AND INDEMNIFICATION

         6.1  PENWEST LIABILITIES; INDEMNIFICATION. Penwest shall indemnify,
defend and hold harmless Penford from and against any and all Liabilities
arising out of or resulting from any of the following items (without
duplication):

              (a)  the employment of Penwest Employees;

              (b)  the business of Penwest and the Penwest Assets;

              (c)  purchase orders, accounts payable, accrued compensation and
other accrued Penwest Liabilities and other agreements which relate to the
business of Penwest and the Penwest Assets; and

              (d)  any misstatement or omission of a material fact other than
misstatements or omissions with respect to Penford based on information supplied
in writing by Penford in any documents or filings prepared for purposes of
compliance or qualification under applicable securities laws in connection with
the Separation, IPO or Distribution and related transactions, including, without
limitation, the Registration Statement.

         6.2  PENFORD LIABILITIES; INDEMNIFICATION. Penford shall indemnify,
defend and hold harmless Penwest from and against any and all Liabilities
arising out of or resulting from any of the following items (without
duplication):

              (a)  the business of Penford and the Liabilities not assumed by
Penwest under the terms of this Agreement or any other agreement or document
contemplated by this Agreement; and

              (b)  any misstatement or omission of a material fact with respect
to Penford based on information supplied in writing by Penford in any documents
or filings prepared for purposes of compliance or qualification under applicable

                                      -16-

<PAGE>   17



securities laws in connection with the Separation, IPO or Distribution and
related transactions, including, without limitation, the Registration Statement.

         6.3  PROCEDURES FOR INDEMNIFICATION OF THIRD PARTY CLAIMS.

              (a)  If any Person entitled to indemnification hereunder (an
"Indemnitee") shall receive notice or otherwise learn of the assertion by a
Person (including any Governmental Authority) of any claim or of the
commencement by any such Person of any Action (collectively, a "Third Party
Claim") with respect to which any party (an "Indemnifying Party") may be
obligated to provide indemnification to such Indemnitee pursuant to Section 6.1
or 6.2, or any other Section of this Agreement or any other agreement or
document contemplated by this Agreement or otherwise, such Indemnitee shall give
such Indemnifying Party written notice thereof within twenty (20) days after
becoming aware of such Third Party Claim. Any such notice shall describe the
Third Party Claim in reasonable detail. Notwithstanding the foregoing, the
failure of any Indemnitee or other Person to give notice as provided in this
Section 6.3(a) shall not relieve the Indemnifying Party of its obligations under
this Article VI, except to the extent that such Indemnifying Party is actually
prejudiced by such failure to give notice.

              (b)  An Indemnifying Party may elect to defend (and, unless the
Indemnifying Party has specified any reservations or exceptions, to seek to
settle or compromise), at such Indemnifying Party's own expense and by such
Indemnifying Party's own counsel, any Third Party Claim. Within thirty (30) days
after the receipt of notice from an Indemnitee in accordance with Section 6.3(a)
(or sooner, if the nature of such Third Party Claim so requires), the
Indemnifying Party shall notify the Indemnitee of its election whether the
Indemnifying Party will assume responsibility for defending such Third Party
Claim, which election shall specify any reservations or exceptions. After notice
from an Indemnifying Party to an Indemnitee of its election to assume the
defense of a Third Party Claim, such Indemnitee shall have the right to employ
separate counsel and to participate in (but not control) the defense,
compromise, or settlement thereof, but the fees and expenses of such counsel
shall be the expense of such Indemnitee except as set forth in Section 6.3(c).

              (c)  If an Indemnifying Party elects not to assume responsibility
for defending a Third Party Claim, or fails to notify an Indemnitee of its
election as provided in Section 6.3(b), such Indemnitee may defend such Third
Party Claim at the cost and expense (including allocated costs of in-house
counsel and other personnel) of the Indemnifying Party.

              (d)  Unless the Indemnifying Party has failed to assume the
defense of the Third Party Claim in accordance with the terms of this Agreement,
no Indemnitee may settle or compromise any Third Party Claim without the consent
of the Indemnifying Party.

                                      -17-

<PAGE>   18



              (e) No Indemnifying Party shall consent to entry of any judgment
or enter into any settlement of the Third Party Claim without the consent of the
Indemnitee if the effect thereof is to permit any injunction, declaratory
judgment, other order or other nonmonetary relief to be entered, directly or
indirectly, against any Indemnitee.

         6.4  TAX LIABILITIES. Notwithstanding the provisions of Sections 6.1
and 6.2, all tax Liabilities relating to the business of Penwest and the Penwest
Assets including, without limitation, income taxes, franchise taxes, sales
taxes, use taxes, payroll taxes and employment taxes, shall be assumed by the
party to whom the Liability has been allocated in the Tax Allocation Agreement.

         6.5  ADDITIONAL MATTERS.

              (a)  Any claim on account of a Liability which does not result
from a Third Party Claim shall be asserted by written notice given by the
Indemnitee to the Indemnifying Party. Such Indemnifying Party shall have a
period of thirty (30) days after the receipt of such notice within which to
respond thereto. If such Indemnifying Party does not respond within such thirty
(30)-day period, such Indemnifying Party shall be deemed to have refused to
accept responsibility to make payment. If such Indemnifying Party does not
respond within such thirty (30)-day period or rejects such claim in whole or in
part, such Indemnitee shall be free to pursue such remedies as may be available
to such party as contemplated by this Agreement.

              (b)  In the event of payment by or on behalf of any Indemnifying
Party to any Indemnitee in connection with any Third Party Claim, such
Indemnifying Party shall be subrogated to and shall stand in the place of such
Indemnitee as to any events or circumstances in respect of which such Indemnitee
may have the right, defense or claim relating to such Third Party Claim against
any claimant or plaintiff asserting such Third Party Claim or against any other
person. Such Indemnitee shall cooperate with such Indemnifying Party in a
reasonable manner, and at the cost and expense (including allocated costs of
in-house counsel and other personnel) of such Indemnifying Party, in prosecuting
any subrogated right, defense or claim.

              (c)  In the event of an Action in which the Indemnifying Party is
not a named defendant, if either the Indemnitee or Indemnifying Party shall so
request, the parties shall endeavor to substitute the Indemnifying Party for the
named defendant. If such substitution or addition cannot be achieved for any
reason or is not requested, the named defendant shall allow the Indemnifying
Party to manage the Action as set forth in this Section and the Indemnifying
Party shall fully indemnify the named defendant against all costs of defending
the Action (including court costs, sanctions imposed by a court, attorneys'
fees, experts' fees and all other

                                      -18-

<PAGE>   19



external expenses, and the allocated costs of in-house counsel and other
personnel), the costs of any judgment or settlement, and the cost of any
interest or penalties relating to any judgment or settlement.

         6.6  REMEDIES CUMULATIVE. The remedies provided in this Article VI
shall be cumulative and shall not preclude assertion by an Indemnitee of any
other rights or the seeking of any and all other remedies against any
Indemnifying Party.

                                   ARTICLE VII

                       ACCESS TO INFORMATION AND SERVICES

         7.1  PROVISION OF CORPORATE RECORDS. Upon Penwest's request, Penford
shall arrange as soon as practicable following the Effective Date for the
delivery to Penwest of existing corporate records in the possession of Penford
relating to the business of Penwest or assets to be transferred to Penwest,
together with all active agreements and active litigation files relating to the
businesses of Penwest, except to the extent such items are already in the
possession of Penwest. Such records shall be the property of Penwest but shall
be available to Penford for review and duplication until Penford shall notify
Penwest in writing that such records are no longer of use to Penford.

         7.2  ACCESS TO INFORMATION. From and after the Effective Date, Penford
shall afford to Penwest and its authorized accountants, counsel and other
designated representatives reasonable access (including using reasonable best
efforts to give access to persons or firms possessing information) and
duplicating rights during normal business hours to all records, books,
contracts, instruments, computer data and other data and information
(collectively, "Information") within Penford's possession relating to the
businesses of Penwest, insofar as such access is reasonably required by Penwest.
Penwest shall afford to Penford and its authorized accountants, counsel and
other designated representatives reasonable access (including using reasonable
best efforts to give access to persons or firms possessing Information) and
duplicating rights during normal business hours to Information within Penwest's
possession relating to the business of Penwest prior to the Distribution or to
the business of Penford, insofar as such access is reasonably required by
Penford. Information may be requested under this Article VII for, without
limitation, audit, accounting, claims, litigation and tax purposes, as well as
for purposes of fulfilling disclosure and reporting obligations and for
performing the transactions contemplated in this Agreement or any other
agreement or document contemplated by this Agreement or otherwise.

         7.3  PENWEST SECURITIES FILINGS. For a period of three years following
the Effective Date, each of Penwest and Penford shall provide to the other,
promptly following such time at which such documents shall be filed with the
Commission,

                                      -19-

<PAGE>   20



copies of all documents which shall be filed by either Penwest or Penford, as
the case may be, with the Commission pursuant to the periodic and interim
reporting requirements of the Exchange Act and the rules and regulations of the
Commission promulgated thereunder.

         7.4  PRODUCTION OF WITNESSES. At all times from and after the Effective
Date, each of Penford and Penwest shall use reasonable best efforts to make
available to the other, upon written request, its officers, directors, employees
and agents as witnesses to the extent that such persons may reasonably be
required, in connection with legal, administrative or other proceedings in which
the requesting party may from time to time be involved.

         7.5  REIMBURSEMENT. Except to the extent otherwise contemplated by any
Ancillary Agreement, a party providing information to the other party under this
Article VII shall be entitled to receive from the recipient, upon the
presentation of invoices therefor, payments for such amounts, relating to
supplies, disbursements and other out-of-pocket expenses, as may be reasonably
incurred in providing such information.

         7.6  RETENTION OF RECORDS. For a period of six (6) years following the
Effective Date, each of Penford and Penwest shall retain all Information
relating to the other as of the Effective Date, except as otherwise required by
law or set forth in an Ancillary Agreement or except to the extent that such
Information is in the public domain or in the possession of the other party.

         7.7  CONFIDENTIALITY. Subject to any contrary requirement of law and
the right of each party to enforce its rights hereunder in any legal action,
each party shall keep strictly confidential, and shall cause its employees and
agents to keep strictly confidential, any Information of or concerning the other
party which it or any of its agents or employees may acquire pursuant to, or in
the course of performing its obligations under, any provisions of this Agreement
or any Ancillary Agreement; provided, however, that such obligation to maintain
confidentiality shall not apply to Information which (i) at the time of
disclosure was in the public domain or (ii) was received by the receiving party
from a third party who did not receive such Information from the disclosing
party under an obligation of confidentiality.

                                  ARTICLE VIII

                                    COVENANTS

                                      -20-

<PAGE>   21



         8.2  ANCILLARY AGREEMENTS. The parties agree that they shall comply
with and provide all services and take any and all actions required to be
provided or taken by the terms of any and all of the Ancillary Agreements
following the Closing Date.

         8.3  SHARING OF UTILITIES

              (a)  Penford agrees that Penwest shall be entitled to use and
consume, in an amount reasonably required, at Penwest's Cedar Rapids facility
certain utilities consisting of natural gas, electricity and steam from
Penford's Cedar Rapids facility. Any material change in the provision of such
utilities shall require six (6) months prior notice.

              (b)  In connection with the sharing of utilities as described in
Section 8.3(a), Penwest will reimburse Penford for its consumption of such
utilities based on Penford's total cost (including maintenance) for each item
and Penwest's fraction of the total consumption.

              (c)  Penford will submit a monthly invoice to Penwest of all
amounts owed by Penwest to Penford with respect to utilities consumed by Penwest
pursuant to Section 8.3(a). The charges will be due when billed and shall be
paid no later than thirty (30) days from the date of billing.

         8.4  NON-COMPETITION

              (a)  From the Effective Date to the longer of (i) five years or
(ii) the termination of the Excipient Supply Agreement, neither Penford nor any
of its Affiliates shall, directly or indirectly, manufacture, market, sell or
distribute for inclusion in any pharmaceutical or nutritional product (including
vitamins, minerals and cofactors, but excluding foods) any product having the
same or substantially the same form, composition or applications as EMDEX or
CANDEX or any similar sugar- based product. From the Effective Date to the
longer of (i) five years or (ii) the termination of the Excipient Supply
Agreement, neither Penwest nor any of its Affiliates shall, directly or
indirectly, manufacture, market, sell or distribute for inclusion in any foods
product any product having the same or substantially the same form, composition
or applications as EMDEX or CANDEX or any similar sugar- based product.

              (b)  For a period of five years from the Effective Date, Penford
shall not directly or indirectly recruit or solicit any employee of Penwest, or
induce or attempt to induce any employee of Penwest to terminate his or her
employment with, or otherwise cease his or her relationship with, Penwest. For a
period of five years from the Effective Date, Penwest shall not directly or
indirectly recruit or solicit any employee of Penford, or induce or attempt to
induce any employee of Penford to

                                      -21-

<PAGE>   22



terminate his or her employment with, or otherwise cease his or her relationship
with, Penford.

              (c)  If any restriction set forth in Sections 8.4 (a) or (b) is
found by any court of competent jurisdiction to be unenforceable because it
extends for too long a period of time or over too great a range of activities or
in too broad a geographic area, it shall be interpreted to extend only over the
maximum period of time, range of activities or geographic area as to which it
may be enforceable.

              (d)  The restrictions contained in this Section 8.4 are necessary
for the protection of the respective businesses and goodwill of Penwest and
Penford and are considered by Penford and Penwest to be reasonable for such
purpose. Penford and Penwest agree that any breach of this Section 8.4 is likely
to cause Penwest or Penford, as the case may be, substantial and irrevocable
damage and therefore, in the event of any such breach, Penwest or Penford, as
the case may be, in addition to such other remedies which may be available,
shall be entitled to specific performance and other injunctive relief.

         8.5  STOCK OPTIONS.

         Prior to the Distribution Date, Penford shall (i) amend its stock plans
to provide that, for purposes of such stock plans, the term employee shall
include all Penwest Employees as of the Record Date, (ii) amend each Penford
stock option held by a Penwest Employee as of the Record Date to provide that
the option will continue to vest for so long as the Penwest Employee remains an
employee of Penwest and (iii) effective as of the Distribution Date, make an
adjustment to the exercise price of each Penford stock option outstanding as of
the Record Date and make an adjustment to the number of shares of Penford Common
Stock under each Penford stock option outstanding as of the Record Date. The
adjustment to the exercise price of such stock option shall be applied by
multiplying the exercise price of the option by a fraction, the numerator of
which shall equal the Penford Market Capitalization and the denominator of which
shall equal the sum of the Penford Market Capitalization and the Penwest Market
Capitalization. The adjustment in the number of shares of Penford Common Stock
shall be applied by multiplying the number of shares of Penford Common Stock
under each Penford stock option as of the Record Date by a fraction, the
numerator of which shall equal the sum of the Penford Market Capitalization and
Penwest Market Capitalization and the denominator of which shall equal the
Penford Market Capitalization. Thus, a holder of an option to purchase one share
of Penford Common Stock at an exercise price of $10 per share shall have the
exercise price of the option reduced from $10 per share to $6.66 per share
(i.e., $10 x 200,000,000/300,000,000 = $6.66 and number of shares increased by
1.5 (i.e. 1 x 300,000,000/200,000,000 = 1.5)).

         8.6  REGISTRATION RIGHTS.

              (a)  REGISTRATION OF SHARES. In the event that the Distribution 
has not occurred by September 30, 1998, upon the request of Penford, Penwest
shall file with the SEC, as promptly as practicable, a resale registration
statement (the "Resale Registration Statement"). Penford shall have the right to
request up to three Resale Registration Statements, provided that Penwest shall
have no obligation to file any such resale registration statement on or prior to
a ninety (90) day period following the filing of any other registration
statement by Penwest. Penwest shall use its reasonable best efforts to cause
each Resale Registration Statement to be declared effective by the SEC as soon
as practicable. If a Resale Registration Statement shall be withdrawn before
effectiveness, it shall not be counted against Penford's right to request three
registrations.

              (b)  LIMITATIONS ON REGISTRATION RIGHTS.

                   (i)   Penwest may, by written notice to Penford, for a period
of up to 45 days from the date of written notice, delay the filing or
effectiveness of any of the Resale Registration Statements in the event that (1)
Penwest is engaged in any activity or transaction that Penwest desires to keep
confidential for business reasons, (2) the Penwest Board of Directors determines
in good faith that the disclosure of such information would be detrimental to
Penwest, and (3) the Penwest Board of Directors determines in good faith that
the public disclosure requirements imposed on Penwest under the Securities Act
in connection with any such Resale Registration Statement would require
disclosure of such activity or transaction.

                   (ii)  If Penwest delays a Resale Registration Statement,
Penwest shall, as promptly as practicable following the termination of the
circumstances which entitled Penwest to do so, take such actions as may be
necessary to file or reinstate the effectiveness of a Resale Registration
Statement. If as a result thereof the prospectus included in a Resale
Registration Statement has been amended to comply with the requirements of the
Securities Act, Penwest shall enclose such revised prospectus with the notice to
Penford given pursuant to this paragraph (ii), and Penford shall make no offers
or sales of shares pursuant to a Resale Registration Statement other than by
means of such revised prospectus.

              (c)  REGISTRATION PROCEDURES.

                   (i)   In connection with the filing by Penwest of a Resale
Registration Statement, Penwest shall furnish to Penford as many copies of the
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act as Penford shall reasonably request for the
purpose of effecting the plan of distribution set forth therein.


                                      -23-

<PAGE>   24



                   (ii)  Penwest shall use its best efforts to register or
qualify the Penwest Common Stock covered by a Resale Registration Statement
under the securities laws of such states as Penford shall reasonably request;
provided, however, that Penwest shall not be required in connection with this
paragraph (ii) to qualify as a foreign corporation or execute a general consent
to service of process in any jurisdiction.

                   (iii) If Penwest has delivered preliminary or final
prospectuses to Penford and after having done so the prospectus is amended to
comply with the requirements of the Securities Act, Penwest shall promptly
notify Penford and, if requested by Penwest, Penford shall immediately return
all prospectuses to Penwest. Penwest shall promptly provide Penford with revised
prospectuses.

                   (iv)  At the request of Penford, Penwest shall sign an
underwriting agreement in customary form with managing underwriters selected by
Penford, and shall cooperate with such managing underwriters in all reasonable
respects to facilitate the distribution contemplated by Penford, including
without limitation making available the books, records and personnel of Penwest
for the purpose of the underwriters' "due diligence" and providing customary
legal opinions and auditors' comfort letters.

                   (v)   Each of Penwest and Penford shall share in equal
amounts the expenses incurred by Penwest in complying with its obligations under
this Section 8.6, including all registration and filing fees, exchange listing
fees, fees and expenses of counsel for Penwest, and fees and expenses of
accountants for Penwest, but excluding (A) any brokerage fees, selling
commissions or underwriting discounts incurred by Penford in connection with
sales under a Resale Registration Statement and (B) the fees and expenses of any
counsel retained by Penford.

              (d)  If Penwest begins preparations to file a registration
statement for sale of securities on a form in which common stock held by Penford
may be included, Penwest shall notify Penford in writing at least thirty (30)
days before filing the registration statement and shall include therein any
Penwest Common Stock that Penford requested to be included.

              (e)  REQUIREMENTS OF PENFORD. Penwest shall not be required to
include any Penwest Common Stock owned by Penford in a Resale Registration
Statement unless:

                   (i)   Penford furnishes to Penwest in writing such
information regarding Penford as Penwest may reasonably request in writing in
connection with the Resale Registration Statement or as shall be required in
connection therewith by the SEC or any state securities law authorities;

                   (ii)  Penford shall have provided to Penwest its written
agreement:

                       (A)  to indemnify Penwest and each of its directors and 
officers against, and hold Penwest and each of its directors and officers
harmless from, any losses, claims, damages, expenses or liabilities (including
reasonable attorneys fees) to which Penwest or such directors and officers may
become subject by reason of any statement or omission in the Resale Registration
Statement made in reliance upon, or in conformity with, any written statement by
Penford furnished pursuant to this Section 8.6(e); and

                       (B)  to report to Penwest sales made pursuant to the 
Resale Registration Statement.

              (f)  Penwest agrees to indemnify and hold harmless Penford against
any losses, claims, damages, expenses or liabilities to which Penford may become
subject by reason of any untrue statements of a material fact contained in the
Resale Registration Statement or any omission to state therein a fact required
to be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, expenses or liabilities arise
out of or are based upon information furnished to Penwest in writing by or on
behalf of Penford for use in the Resale Registration Statement. Penwest shall
have the right to assume the defense and settlement of any claim or suit for
which Penwest may be responsible for indemnification under this Section 8.6(f).

              (g)  ASSIGNMENT OF RIGHTS. Penford may not assign any of its 
rights under this Section 8.6.

         8.7  MUTUAL ASSURANCES.

              (a)  In addition to the actions specifically provided for
elsewhere in this Agreement or any other agreement or document contemplated by
this Agreement or otherwise, Penford and Penwest agree to cooperate with respect
to the implementation of this Agreement or any other agreement or document
contemplated by this Agreement or otherwise, and to execute such further
documents and instruments as may be necessary to consummate and make effective
the transactions contemplated by this Agreement or any other agreement or
document contemplated by this Agreement or otherwise;

              (b)  Penford and Penwest shall arrange, attend and participate in
joint meetings with corporate collaborators, suppliers, customers and others to
the extent necessary to assure the orderly transition of the business and assets
contemplated hereby, provided that nothing herein shall be deemed to obligate
either Penford or

                                      -25-

Penwest to take any action or reach any understandings which may violate any
applicable laws.

              (c)  Penford and Penwest agree to take any reasonable actions
necessary in order for the Distribution to qualify as a tax-free distribution
pursuant to Sections 355 and 368 of the Code.

              (d)  Penford and Penwest agree that they shall not take any action
which could reasonably be expected to prevent the Distribution from qualifying
as a tax-free distribution within the meaning of Sections 355 and 368 of the
Code or any other transaction contemplated by this Agreement or any other
agreement or document contemplated by this Agreement or otherwise which is
intended by the parties to be tax-free from failing so to qualify. Without
limiting the foregoing, after the Closing Date and on or prior to the
Distribution Date, Penwest shall not issue or grant, directly or indirectly, any
shares of Penwest Common Stock or any rights, warrants, options or other
securities to purchase or acquire (whether upon conversion, exchange or

convertible or exchangeable).

officers) shall have any Liability or further obligation to any other party.

              (b)  In the event of any termination of this Agreement on or after
the Closing Date, only the provisions of Article IV will terminate and the other
provisions of this Agreement or any agreement or document contemplated by this
Agreement or otherwise shall remain in full force and effect.

shall inure to the benefit of the parties hereto and their respective successors
and assigns, provided that this Agreement and the rights and obligations

shall consult with each other prior to issuing any press releases or otherwise
making public statements with respect to the IPO, the Distribution or any of the

         10.10 HEADINGS. The article, section and paragraph headings contained
in this Agreement and in the Ancillary Agreements are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement or any Ancillary Agreement.

         10.11 ARBITRATION. Any dispute, controversy or claim arising out of or
in connection with this Agreement or any of the Ancillary Agreements (including
any questions of fraud or questions concerning the validity and enforceability
of this Agreement or any of the Ancillary Agreements or any of the rights herein
and therein conveyed), shall be determined and settled by arbitration in
Seattle, Washington, pursuant to the rules then in effect of the American
Arbitration Association as modified by this paragraph. Any award rendered shall
be final and conclusive upon the parties and a judgment thereon may be entered
in any court having competent jurisdiction. The party submitting such dispute
shall give written notice to that effect to the other party, stating the dispute
to be arbitrated and the name and address of a person designated to act as
arbitrator on its behalf. Within fifteen (15) days after such notice, the other
party shall give written notice to the first party stating the name and address
of a person designated to act as an arbitrator on its behalf. In the event that
the second party shall fail to notify the first party of its designation of an
arbitrator within the time specified, then the first party shall request the
American Arbitration Association to appoint a second arbitrator. The two
arbitrators so chosen shall meet within fifteen (15) days after the second
arbitrator has been appointed to appoint a third arbitrator. If the two
arbitrators are unable to agree on the appointment of a third arbitrator within
such fifteen (15) day period, either party may request the American Arbitration
Association to appoint a third arbitrator. Each arbitrator appointed hereunder
shall be independent of the parties and either party may disqualify an
arbitrator who is or is affiliated with a supplier, customer or competitor of
either party without the consent of the other party. Each

                                      -28-

arbitrator shall be reasonably knowledgeable regarding the area or areas in
dispute. The arbitrators shall follow substantive rules of law and the Federal
Rules of Evidence, require the parties to conduct discovery pursuant to the
rules then in effect under the Federal Rules of Civil Procedure in an
expeditious manner, cause testimony to be transcribed, and make an award
accompanied by findings of fact and a statement of reasons for the decision. All
costs and expenses, including attorney's fees, of all parties incurred in any
dispute which is determined and/or settled by arbitration pursuant to this
paragraph shall be borne by the party determined to be liable in respect of such
dispute; provided, however, that if complete liability is not assessed against
only one party, the parties shall share the total costs in proportion to their
respective amounts of liability so determined. Except where clearly prevented by
the area in dispute, both parties agree to continue performing their respective
obligations under this Agreement while the dispute is being resolved. Each
party, and the arbitrators, shall use their best efforts, subject to reasonable
prosecution of the arbitration, court order and disclosure required under
securities laws, to keep the subject matter of the arbitration and confidential
information of each party confidential, and the arbitrators are authorized to
impose such protective orders as they may deem appropriate for such purpose.

         10.12 ENTIRE AGREEMENT. This Agreement contains the full understanding
of the parties with respect to the subject matter hereof and supersedes all
prior understandings and writings relating thereto. No waiver, alteration or
modification of any of the provisions hereof shall be binding unless made in
writing and signed by the parties.
