                    NOTES TO FINANCIAL STATEMENTS (Unaudited)


1.    BASIS OF PRESENTATION

          The accompanying  unaudited financial statements have been prepared in
     accordance  with  generally  accepted  accounting  principles  for  interim
     financial  information,  pursuant  to  the  rules  and  regulations  of the
     Securities  and  Exchange  Commission.  In the opinion of  management,  all
     adjustments (consisting of normal, recurring accruals) considered necessary
     for fair  presentation  have been included.  Operating  results for the six
     months ended June 30, 1997, are not  necessarily  indicative of the results
     that may be expected for the year ended December 31, 1997.  These financial
     statements  should  be read  in  conjunction  with  the  audited  financial
     statements and accompanying notes contained in the Annual Report of GalaGen
     Inc. (the  "Company")  on Form 10-K for the fiscal year ended  December 31,
     1996.

2.    CASH AND CASH EQUIVALENTS

          Cash  equivalents   include   short-term  highly  liquid   investments
     purchased at cost, which approximate  market,  with original  maturities of
     three months or less.

3.    INVESTMENTS

          Investments in debt securities with a remaining  maturity of more than
     three months at the date of purchase are  classified as  available-for-sale
     securities.  Management  determines the appropriate  classification of debt
     securities at the time of purchase and reevaluates  such  designation as of
     each balance  sheet date.  The book value of the  investments  approximates
     their estimated  market value. The estimated market value of investments by
     security type is as follows:

                                                   Estimated Market Value

5.   LINE-OF-CREDIT

          In June 1997, the Company established a $2,000,000  line-of-credit for
     fixed assets with  Transamerica  Business Credit  Corporation which extends
     through June 1998.  Terms of the  line-of-credit  include monthly  payments
     over four  years  equal to  2.5782% of each  advance  with a final  balloon
     payment of 12.5% at the end of the four year period.  The line-of-credit is
     secured by the Company's fixed assets.  TransAmerica received a warrant for
     40,000  shares of common stock granted at the fair market value on the date
     of grant. The Company drew  approximately  $1,319,000 of the line-of-credit
     in July 1997.


6.    NET LOSS PER SHARE

          Net loss per share is computed  using the weighted  average  number of
     shares of common stock outstanding during the periods presented.  The fully
     diluted  loss  per  share  assumes  the  conversion  of  preferred   shares
     outstanding prior to the Company's initial public offering (the "Offering")
     to common shares as of the beginning of the period.  The loss per share for
     periods  prior to the closing date of the Offering also gives effect to the
     requirements of Staff Accounting Bulletin No. 83 (SAB 83).

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

Forward-Looking Statements

     The information presented in this Item contains forward-looking  statements
within  the  meaning  of  the  safe  harbor  provisions  of  Section  21E of the
Securities  Exchange Act of 1934,  as amended.  Such  statements  are subject to
risks and  uncertainties,  including those discussed under "Risk Factors" below,
that could  cause  actual  results to differ  materially  from those  projected.
Because  actual  results may differ,  readers are  cautioned  not to place undue
reliance on these forward-looking statements. Certain forward-looking statements
are indicated below by an asterisk.

Recent Developments

     In August 1997,  the Company  announced it is  increasing  its  development
efforts  on  Diffistat-G,  its  pharmaceutical  product  for  the  treatment  of
antibiotic-associated  diarrhea,  and  development  efforts  on its  nutritional
products.  At the same time,  the  Company  announced  that it was  placing  its
Sporidin-G  clinical  trial on hold due to  continuing  decline  in the  patient
population for the product's initial  indication,  AIDS-related  Cryptosporidium
parvum  infection,  brought about by the  effectiveness and increased use of new
AIDS therapies,  including  protease  inhibitors and earlier  administration  of
combination  therapy.  The Company believes that its expenses and losses for the
three months ended September 30, 1997 will increase due to the costs  associated
with placing the  Sporidin-G  clinical  trial on hold.  Thereafter,  the Company
expects that expenses and losses for the three month periods ended  December 31,
1997,  March 31,  1998 and June 30,  1998 are  expected  to  decrease  to levels
experienced  for the three  month  period  ended  June 30,  1997,  as  increased
expenses  associated  with the  development  efforts of Diffistat-G  and certain
nutritional  products offset the reduction of Sporidin-G  expenses.* The Company
believes  that  significant  expenses  and losses  will be  incurred  before any
material product revenues are generated.*


Results of Operations

Three Months Ended June 30, 1997 and 1996

     General.  The net loss before preferred stock dividends decreased $480,749,
or 24.8%, for the three months ended June 30, 1997 to $1,456,566 from $1,937,315
for the same  period  in 1996.  The  decrease  was due  primarily  to  decreased
interest  expense  offset by increased  general and  administrative  expense and
decreased interest income.

     Research And  Development  Expenses.  Expenses for research and development
decreased  $52,510,  or 4.8%, to $1,036,352  for the three months ended June 30,
1997 from  $1,088,862 for the three months ended June 30, 1996. The decrease was
due primarily to decreased clinical trial expenses associated with Sporidin-G of
approximately  $312,000 offset by increased  clinical trial expenses  associated
with   Diffistat-G  of   approximately   $147,000  and  increased   expenses  of
approximately  $113,000 relating to the Company's other research and development
activities. As discussed above, the Company expects the research and development
expenses to increase for the three months  ended  September  30, 1997 due to the
expenses  associated  with placing the  Sporidin-G  clinical  trial on hold, and
thereafter  the expenses for the three month  periods  ended  December 31, 1997,
March 31, 1998 and June 30, 1998 are expected to decrease to levels  experienced
for the three month period ended June 30, 1997.

     General And Administrative  Expenses.  General and administrative  expenses
increased  $97,680,  or 22.3%,  to $535,099  for the three months ended June 30,
1997 from  $437,419  for the same period in 1996.  Approximately  $70,000 of the
increase was due to increased  outside service charges.  As discussed above, the
Company  expects  the general and  administrative  expenses to increase  for the
three  months  ended  September  30, 1997 due to the  expenses  associated  with
placing the Sporidin-G  clinical trial on hold , and thereafter the expenses for
the three month  periods  ended  December 31, 1997,  March 31, 1998 and June 30,
1998 are expected to decrease to levels  experienced  for the three month period
ended June 30, 1997.

     Interest Income. Interest income decreased to $114,885 for the three months
ended June 30, 1997 from $202,865 for the three months ended June 30, 1996. This
$87,890 decrease,  or 43.4%, is attributable to the Company's decreased level of
investable funds.

                                       8
<PAGE>

     Interest Expense. Interest expense was zero for the three months ended June
30, 1997 and $613,899  for the three  months  ended June 30, 1996.  The interest
expense in 1996 was due to the  valuation of warrants  issued both to guarantors
of a line  of  credit  for  the  Company  and  to  purchasers  of the  Company's
Convertible Promissory Notes.

     Preferred  Stock  Dividends.   The  preferred  stock  dividend  expense  of
$7,296,844 for the three months ended June 30, 1996  represents the value of the
additional  shares issued during the period to holders of the Series D, Series E
and Series F-1 Preferred Stock upon conversion to Common Stock.

     Six Months Ended June 30, 1997 and June 30, 1996

     General.  The net loss before preferred stock dividends decreased $375,054,
or 11%, to $3,033,494 for the six months ended June 30, 1997 from $3,408,548 for
the six months ended June 30, 1996.  The decrease was primarily due to decreased
interest  expense  offset by  increased  research  and  development  expense and
increased general and administrative expense.

     Research And  Development  Expenses.  Expenses for research and development
increased  $369,845,  or 20.7%.  to  $2,155,566  for the six  months  ended June
30,1997 from  $1,785,721  for the six months ended June 30, 1996.  Approximately
$153,000  was  due  to  increased   clinical  trial  expenses   associated  with
Diffistat-G,   approximately   $151,000  was  due  to  increased  personnel  and
associated expenses,  approximately  $150,000 was attributable to an increase in
other research and development activities including expenditures associated with
nutritional products and an increase of approximately $86,000 was from increased
pilot  plant  operating  expenses.  These  increases  were  offset by  decreased
expenses of $182,000 related to Sporidin-G clinical trial activity.

     General And Administrative  Expenses.  General and administrative  expenses
increased  $196,425,  or 21.5%,  to $1,109,095 for the six months ended June 30,
1997 from $912,670 for the six months ended June 30, 1996.  The increase was due
to increased personnel related expenses of approximately  $101,000 and increased
outside service expenses of approximately $95,000.

     Interest  Income.  Interest income increased to $231,167 for the six months
ended June 30, 1997 from  $207,945 for the six months ended June 30, 1996.  This
$23,222  increase,  or 11.2%, is attributable to increased  interest income from
the  investment  of funds  received by the Company from the  Offering  offset by
decreased interest income due to the decreased level of investable funds.

       Interest Expense. Interest expense was zero for the six months ended June
30, 1997 and  $918,102  for the six months  ended June 30,  1996.  The  interest
expense in 1996 was due to interest  associated  with the Company's  Convertible
Promissory  Notes and to the value of warrants  issued both to  guarantors  of a
line of credit for the Company and to purchasers  of the  Company's  Convertible
Promissory Notes.

     Preferred  Stock  Dividends.   The  preferred  stock  dividend  expense  of
$7,296,844  for the six months ended June 30, 1996  represents  the value of the
additional shares issued during such period to holders of the Series D, Series E
and Series F-1 Preferred Stock upon conversion to Common Stock.


     Liquidity and Capital Resources

     The Company was incorporated in March 1992. On July 24, 1992,  Procor,  the
Company's predecessor, was merged with and into the Company (the "Procor-GalaGen
Merger").  At the time of the Procor-GalaGen  Merger,  Procor was a wholly-owned
subsidiary of Land O'Lakes, Inc. ("Land O'Lakes"). Since the Company's inception
through June 30,  1997,  investments  in the Company have totaled  approximately
$50.6 million, including approximately $7.1 million of inter-company obligations
payable to Land O'Lakes which were forgiven and recorded as contributed  capital
at the time of the Procor-GalaGen Merger, $17.9 million from the Offering (after
deducting  underwriting discounts and offering expenses) and approximately $25.6
million  from  private  placements  of  equity  and  convertible  debt  and from
conversion  of accrued  interest on such debt and the exercise of stock  options
and warrants.  The Company has invested funds received in the Offering and these
private placements in investment-grade, interest-bearing obligations.

     In June 1997, the Company established a $2,000,000 line-of-credit for fixed
assets with Transamerica  Business Credit Corporation which extends through June
1998. Terms of the line-of-credit include monthly payments over four years equal
to 2.5782% of each advance with a final  balloon  payment of 12.5% at the end of
four years.  The 


                                       9
<PAGE>

line-of-credit  is secured by the Company's fixed assets.  The Company currently
has  approximately  $1,700,000 of fixed assets in which it can receive  advances
against, and drew approximately $1,319,000 of the line-of-credit in July 1997.

     In August 1997,  the Company  announced it is  increasing  its  development
efforts  on  Diffistat-G,  its  pharmaceutical  product  for  the  treatment  of
antibiotic-associated  diarrhea,  and  development  efforts  on its  nutritional
products.  At the same time,  the  Company  announced  that it was  placing  its
Sporidin-G  clinical  trial on hold due to  continuing  decline  in the  patient
population for the product's initial  indication,  AIDS-related  Cryptosporidium
parvum  infection,  brought about by the  effectiveness and increased use of new
AIDS therapies,  including  protease  inhibitors and earlier  administration  of
combination  therapy.  The Company believes that its expenses and losses for the
three months ended September 30, 1997 will increase due to the costs  associated
with placing the  Sporidin-G  clinical  trial on hold.  Thereafter,  the Company
expects that expenses and losses for the three month periods ended  December 31,
1997,  March 31,  1998 and June 30,  1998 are  expected  to  decrease  to levels
experienced  for the three  month  period  ended  June 30,  1997,  as  increased
expenses  associated  with the  development  efforts of Diffistat-G  and certain
nutritional  products offset the reduction of Sporidin-G  expenses.* The Company
believes  that  significant  expenses  and losses  will be  incurred  before any
material product revenues are generated.*

     Cash used in operating  activities  decreased by $53,966,  or 1.4%, for the
six months ended June 30, 1997 to $3,830,587 from $3,884,553 for the same period
in 1996.  Cash used in operations  for the six month periods ended June 30, 1997
and 1996 went  primarily to fund  operating  losses and for repayment of current
liabilities.

     For the six months ended June 30, 1997 the Company  redeemed  $2,082,688 of
its  available-for-sale  securities.  The Company invested $204,456 in equipment
and tenant  improvements  related to the  Company's  pilot  plant  manufacturing
facility for the six months ended June 30, 1997 and $129,064 for the same period
in 1996. The Company invested $58,526 for the six months ended June 30, 1997 and
$20,445 for the same period in 1996 in lab  equipment,  computer  equipment  and
software and furniture used primarily to support the Company's operations.

     The Company  anticipates  that its existing  resources and interest thereon
will  be  sufficient  to  satisfy  its  anticipated  cash  requirements  through
approximately the third quarter of 1998.*

     The  Company  expects  to  incur   significant   additional   research  and
development  and other costs,  including costs related to clinical  studies,  as
well as capital  expenditures  necessary to obtain licensure of the existing GMP
pilot  plant  facility  and  to  establish   additional   commercial  scale  GMP
manufacturing  relationships,  before any material  revenues are generated.  The
Company will need to raise substantial  additional funds for longer term product
development, manufacturing and marketing activities it plans to undertake in the
future.  The Company's ability to continue funding its planned operations beyond
the third  quarter of 1998 is  dependent  upon its ability to obtain  additional
funds through equity or debt financing,  strategic alliances, license agreements
or from other financing  sources.  A lack of adequate  funding could  eventually
result in the insolvency or bankruptcy of the Company. At a minimum, if adequate
funds are not  available,  the Company may be required to delay or to  eliminate
expenditures  for  certain of its product  development  efforts or to license to
third  parties the rights to  commercialize  products or  technologies  that the
Company  would  otherwise  seek to  develop  itself.  Because  of the  Company's
significant  long-term  capital  requirements,  it may seek to raise  funds when
conditions  are  favorable,  even if it does not have an immediate need for such
additional  capital at such time.  If the Company has not raised  funds prior to
such time as the Company's needs for funding become  immediate,  the Company may
be forced to raise funds when conditions are  unfavorable  which could result in
dilution to the Company's current stockholders.

     Risk Factors

     Certain  statements  made above,  including  those indicated by an asterisk
(some of which  are  summarized  below),  are  forward-looking  statements  that
involve risks and  uncertainties,  and actual  results may differ.  Factors that
could cause actual results to differ include those identified below.

     Expectation  that  expenses  and losses will  increase for the three months
ending  September 30, 1997 and  thereafter  decrease for the three month periods
ending December 31, 1997, March 31, 1997 and June 30, 1998 to levels experienced
during  the  three  months  ended  June 30,  1997.  The  Company's  products  in
development  will require  additional  research and  development  and  extensive
clinical  testing and regulatory  approval prior to any  commercial  sales.  The
amount  and  timing of  expenses  associated  with  product  development  may be
affected by any changes to trial  protocols  required by the U.S.  Food and Drug
Administration ("FDA"), the rate at which patients meeting trial criteria can be
found and enrolled,  the impact of any new, competitive  therapies on the target
patient 


                                       10

population and any other problems  encountered in clinical trials, some of which
could cause the Company or the FDA to suspend  clinical  trials.  The Company or
the FDA may  suspend  clinical  trials at any time if the  subjects  or patients
participating  in such trials are thought to be exposed to  unacceptable  health
risks.  Factors that could effect anticipated  expenses  associated with placing
the  Sporidin-G  trial on hold include  closing  certain trial sites,  closing a
laboratory testing site and certain clinical analysis that may be performed.

     Anticipated  increase in development  efforts on  nutritional  products and
associated  expenses.  The  Company  has,  under a license  agreement  with Land
O'Lakes,  agreed not to compete for 15 years in the area of nutritional products
based on polyclonal  antibody  technology  except in the area of infant formula.
Accordingly,  the development of nutritional  products would require the consent
of Land O'Lakes.  In March 1997,  Land O'Lakes granted rights to the Company for
the  commercialization  of nutritional  kefir-based  products.  In May 1997, the
Company  signed  an  agreement  with  Lifeway  Foods,   Inc.  to   commercialize
kefir-based products. No assurance can be given that such consent would be given
by  Land  O'Lakes  in a  particular  case.  The  Company  may  curtail  proposed
development  efforts  in  nutritional  foods  if  appropriate  consents  are not
obtained.

     Ability of the Company to satisfy its anticipated cash requirements through
approximately  the third  quarter of 1998.  The  Company's  working  capital and
capital  requirements will depend upon numerous factors,  including the progress
of the Company's  clinical trials and research and development  programs and the
timing  and  cost of  obtaining  regulatory  approvals.  The  Company's  capital
requirements  also  will  depend  on the  levels  of  resources  devoted  to the
development of manufacturing and marketing capabilities, technological advances,
the status of  competitive  products and the ability of the Company to establish
strategic alliances to provide research and development funding to the Company.

ability to perform its obligations under the Loan Documents, or (iii) the rights
of the Lender hereunder.

     SECTION 4.2. Due Execution,  etc. The execution,  delivery, and performance
by the Borrower of each of the Loan  Documents to which it is a party are within
the powers of the Borrower, do not


                                       4
<PAGE>


contravene the organizational documents, if any, of the Borrower, and do not (a)
violate  any  law or  regulation,  or any  order  or  decree  of  any  court  or
governmental  authority,  (b)  conflict  with  or  result  in a  breach  of,  or
constitute a default under, any material indenture,  mortgage,  or deed of trust
or any material lease, agreement, or other instrument binding on the Borrower or
any of its properties, or (c) require the consent, authorization by, or approval
of or notice to or filing or  registration  with any  governmental  authority or
other Person.  This  Agreement is, and each of the other Loan Documents to which
the Borrower is or will be a party, when delivered hereunder or thereunder, will
be, the legal, valid, and binding obligation of the Borrower enforceable against
the  Borrower in  accordance  with its terms,  except as  enforceability  may be
limited by bankruptcy,  insolvency,  or similar laws affecting creditors' rights
generally and by general principles of equity.

     SECTION  4.3.  Solvency;  No Liens.  The  Borrower  is Solvent  and will be
Solvent upon the completion of all transactions  contemplated to occur hereunder
(including,  without limitation, the Loan to be made on the Effective Date); the
security  interests  granted herein constitute and shall at all times constitute
the first and only liens on the Collateral  other than Permitted  Liens; and the
Borrower is, or will be at the time additional Collateral is acquired by it, the
absolute  owner of the  Collateral  with full  right to pledge,  sell,  consign,
transfer,  and create a security interest therein, free and clear of any and all
claims or liens in favor of any other Person other than Permitted Liens.

     SECTION 4.4. No Judgments, Litigation. No judgments are outstanding against
the  Borrower  nor is  there  now  pending  or,  to the  best of the  Borrower's
knowledge after diligent inquiry, threatened any litigation, contested claim, or
governmental  proceeding by or against the Borrower except judgments and pending
or threatened litigation,  contested claims, and governmental  proceedings which
would not, in the aggregate, have a Material Adverse Effect on the Borrower.

     SECTION  4.5.  No  Defaults.  The  Borrower  is not in  default  or has not
received a notice of default under any material  contract,  lease, or commitment
to which it is a party or by which it is bound. The Borrower knows of no dispute

Effect on the Borrower.

     SECTION 4.6.  Collateral  Locations.  On the date hereof,  each item of the
Collateral  is  located at the place of  business  specified  in the  applicable
Schedule.

     SECTION 4.7. No Events of Default.  No Event of Default has occurred and is
continuing  nor has any event occurred  which,  with the giving of notice or the
passage of time, or both, would constitute an Event of Default.

none of the Collateral is subject to contractual  obligations  that may restrict
or inhibit the Lender's rights or abilities to sell or dispose of the Collateral
or any part thereof after the occurrence of an Event of Default.

     SECTION  4.9.Perfection and Priority of Security  Interest.  This Agreement
creates a valid and,  upon  completion  of all  required  filings  of  financing
statements,  perfected  first  priority and exclusive  security  interest in the
Collateral, securing the payment of all the Obligations.

     SECTION 4.10.  Model and Serial  Numbers.  The Schedules set forth the true
and  correct  model  number and  serial  number of each item of  Equipment  that

and information heretofore,  contemporaneously,  or hereafter furnished by or on
behalf  of the  Borrower  in  writing  to the  Lender or for  purposes  of or in
connection  with this Agreement or any other Loan Document,  or any  transaction
contemplated hereby or thereby, are or will be true and accurate in all material
respects on the date as of which such data,  reports,  and information are dated
or certified and not incomplete by omitting to state any material fact necessary
to make such data,  reports,  and information not misleading at such time. There
are no facts now known to the Borrower  which  individually  or in the aggregate
would  reasonably be expected to have a Material  Adverse  Effect and which have
not been specified herein, in the Financial  Statements,  or in any certificate,
opinion, or other written statement (including  Borrower's reports on Forms 10-K
and 10-Q) previously furnished by the Borrower to


                                       5
<PAGE>


the Lender.

     SECTION 4.12.  Price of Equipment.  The cost of each item of Equipment does
not exceed the fair and usual price for such type of equipment purchased in like
quantity and reflects all  discounts,  rebates and  allowances for the Equipment

testing, or other services) given to the Borrower by the manufacturer, supplier,
or any other person.

     SECTION 5. COVENANTS OF THE BORROWER.

and its current yearly  accounting  cycle, (b) maintain in full force and effect
all licenses, bonds, franchises,  leases,  trademarks,  patents,  contracts, and
other rights  necessary or desirable to the  profitable  conduct of its business
unless the failure to do so could not  reasonably be expected to have a Material
Adverse  Effect on the Borrower,  (c) continue in, and limit its  operations to,
the same general lines of business as those presently  conducted or contemplated
by it, and (d) comply with all applicable  laws and  regulations of any federal,
state, or local governmental authority, except for such laws and regulations the
violations of which would not, in the aggregate,  have a Material Adverse Effect
on the Borrower.

     SECTION 5.2.  Notice to the Lender.  As soon as possible,  and in any event
within five days after the Borrower  learns of the following,  the Borrower will
give written notice to the Lender of (a) any proceeding instituted or threatened
to be instituted  by or against the Borrower in any federal,  state,  local,  or
foreign court or before any commission or other regulatory body (federal, state,
local, or foreign)  involving a sum, together with the sum involved in all other
similar  proceedings,  in excess of $50,000 in the  aggregate,  (b) any contract
that is terminated or amended and which has had or could  reasonably be expected
to have a Material  Adverse  Effect on the Borrower,  (c) the  occurrence of any
Material Adverse Change with respect to the Borrower,  and (d) the occurrence of
any Event of Default or event or condition  which,  with notice or lapse of time
or both, would constitute an Event of Default,  together with a statement of the
action which the Borrower has taken or proposes to take with respect thereto.

     SECTION 5.3.  Maintenance of Books and Records.  The Borrower will maintain
books and records  pertaining to the Collateral in such detail,  form, and scope
as the Lender shall require in its commercially reasonable judgment.  Subject to
the consent of Borrower's landlord,  Land O'Lakes,  Inc. (which consent Borrower
shall use its best efforts to obtain),  the  Borrower  agrees that the Lender or
its agents may enter upon the  Borrower's  premises at any time and from time to
time during  normal  business  hours,  and at any time upon the  occurrence  and
continuance of an Event of Default, for the purpose of inspecting the Collateral
and any and all records pertaining thereto.

     SECTION  5.4.  Insurance.  The  Borrower  will  maintain  insurance  on the
Collateral under such policies of insurance,  with such insurance companies,  in
such amounts,  and covering such risks as are at all times  satisfactory  to the
Lender.  All such policies on Equipment shall be made payable to the Lender,  in
case of loss,  under a standard  non-contributory  "lender" or  "secured  party"
clause and are to contain  such other  provisions  as the Lender may  reasonably
require to protect the Lender's  interests in the Collateral and to any payments
to be made under such  policies.  Certificates  of insurance  policies are to be
delivered to the Lender,  premium prepaid,  with the loss payable endorsement in
the  Lender's  favor,  and shall  provide for not less than  thirty  days' prior
written notice to the Lender, of any alteration or cancellation of coverage.  If
the Borrower  fails to maintain such  insurance,  the Lender may arrange for (at
the Borrower's  expense and without any responsibility on the Lender's part for)
obtaining  the  insurance.  Unless the  Lender  shall  otherwise  agree with the
Borrower in writing,  the Lender  shall have the sole right,  in the name of the
Lender or the Borrower,  to file claims under any insurance policies, to receive
and give  acquittance  for any payments that may be payable  thereunder,  and to
execute any endorsements,  receipts, releases,  assignments,  reassignments,  or
other documents that may be necessary to effect the collection,  compromise,  or
settlement of any claims under any such insurance policies.

     SECTION  5.5.   Taxes.   The  Borrower  will  pay,  when  due,  all  taxes,
assessments,  claims,  and other charges  ("Taxes")  lawfully levied or assessed
against  the  Borrower  or the  Collateral  other  than  taxes  that  are  being
diligently  contested in good faith by the Borrower by  appropriate  proceedings
promptly instituted and for which an adequate reserve is being maintained by the
Borrower in  accordance  with GAAP.  If any Taxes  remain  unpaid after the date
fixed for the payment thereof,  or if any lien shall be claimed therefor,  then,


                                       6
<PAGE>


without notice to the Borrower, but on the Borrower's behalf, the Lender may pay
such Taxes, and the amount thereof shall be included in the Obligations.

     SECTION  5.6.  Borrower  to  Defend  Collateral  Against  Claims;  Fees  on
Collateral.  The  Borrower  will  defend the  Collateral  against all claims and
demands of all Persons at any time  claiming the same or any  interest  therein.
The Borrower will not permit any notice creating or otherwise  relating to liens
on the  Collateral  or any portion  thereof to exist or be on file in any public
office  other than  Permitted  Liens.  The Borrower  shall  promptly  pay,  when
payable, all transportation,  storage, and warehousing charges and license fees,
registration  fees,  assessments,  charges,  permit fees, and taxes  (municipal,
state,  and federal)  which may now or hereafter be imposed upon the  ownership,
leasing, renting,  possession,  sale, or use of the Collateral, other than taxes
on or measured by the Lender's income and fees, assessments,  charges, and taxes
which are being  contested in good faith by appropriate  proceedings  diligently
conducted  and with respect to which  adequate  reserves are  maintained  to the
extent required by GAAP.

     SECTION 5.7. No Change of Location,  Structure,  or Identity.  The Borrower
will not (a) change the location of its chief executive  office or establish any
place of business  other than those  specified  herein or (b) move or permit the
movement of any item of Collateral from the location specified in the applicable
Schedule,  except that the  Borrower may change its chief  executive  office and
keep  Collateral at other  locations  within the United States provided that the
Borrower has delivered to the Lender (i) prior written  notice  thereof and (ii)
duly executed financing  statements and other agreements and instruments (all in
form and substance  satisfactory to the Lender)  necessary or, in the opinion of
the Lender,  desirable  to perfect  and  maintain in favor of the Lender a first
priority  security interest in the Collateral.  Notwithstanding  anything to the
contrary  in the  immediately  preceding  sentence,  the  Borrower  may keep any
Collateral  consisting of motor vehicles or rolling stock at any location in the
United  States  provided  that  the  Lender's  security  interest  in  any  such
Collateral is  conspicuously  marked on the certificate of title thereof and the
Borrower has complied with the provisions of Section 5.9.

     SECTION 5.8. Use of Collateral;  Licenses;  Repair. The Collateral shall be
operated by competent,  qualified  personnel in connection  with the  Borrower's
business purposes,  for the purpose for which the Collateral was designed and in
accordance  with  applicable  operating   instructions,   laws,  and  government
regulations,  and the Borrower shall use every reasonable  precaution to prevent
loss or damage to the  Collateral  from fire and other  hazards.  The Collateral
shall not be used or operated for personal,  family, or household purposes.  The
Borrower   shall   procure  and   maintain  in  effect  all  orders,   licenses,
certificates,  permits,  approvals,  and consents required by federal, state, or
local laws or by any governmental  body, agency, or authority in connection with
the delivery,  installation,  use, and operation of the Collateral. The Borrower
shall  keep  all  of  the  Equipment  in a  satisfactory  state  of  repair  and
satisfactory operating condition in accordance with industry standards, and will
make all repairs and  replacements  when and where necessary and practical.  The
Borrower will not waste or destroy the  Equipment or any part thereof,  and will
not be negligent in the care or use thereof.

     SECTION 5.9. Further  Assurances.  The Borrower will, promptly upon request
by the  Lender,  execute  and  deliver  or use its best  efforts  to obtain  any
document required by the Lender (including, without limitation,  warehouseman or
processor disclaimers, mortgagee waivers, landlord disclaimers, or subordination
agreements  with  respect  to the  Obligations  and the  Collateral),  give  any
notices,  execute  and  file  any  financing  statements,  mortgages,  or  other
documents  (all in form and  substance  satisfactory  to the  Lender),  mark any
chattel paper,  deliver any chattel paper or instruments to the Lender, and take
any other actions that are necessary or, in the opinion of the Lender, desirable
to perfect or continue  the  perfection  and the first  priority of the Lender's
security  interest  in the  Collateral,  to protect the  Collateral  against the
rights,  claims, or interests of any Persons,  or to effect the purposes of this
Agreement.  A carbon,  photographic,  or other reproduction of this Agreement or
any  financing  statement  covering the  Collateral or any part thereof shall be
sufficient  as a  financing  statement  where  permitted  by law.  To the extent
required  under this  Agreement,  the  Borrower  will pay all costs  incurred in
connection with any of the foregoing.

     SECTION 5.10. No Disposition  of  Collateral.  The Borrower will not in any
way  hypothecate  or create or  permit  to exist  any lien,  security  interest,
charge, or encumbrance on or other interest in any of the Collateral, except for
the lien and security  interest  granted  hereby and  Permitted  Liens which are
junior to the lien and security  interest of the Lender,  and the Borrower  will
not sell, transfer, assign, pledge,  collaterally assign, exchange, or otherwise
dispose of any of the Collateral  except in the ordinary course of business.  In
the event the


                                       7
<PAGE>


Collateral, or any part thereof, is sold, transferred,  assigned,  exchanged, or
otherwise disposed of in violation of these provisions, the security interest of
the Lender shall  continue in such  Collateral  or part thereof  notwithstanding
such  sale,  transfer,  assignment,  exchange,  or  other  disposition,  and the
Borrower will hold the proceeds thereof in a separate account for the benefit of
the Lender.  Following  such a sale, the Borrower will transfer such proceeds to
the Lender in kind.

     SECTION 5.11. No Limitation on Lender's Rights. The Borrower will not enter
into any  contractual  obligations  which may  restrict or inhibit the  Lender's
rights or ability to sell or  otherwise  dispose of the  Collateral  or any part
thereof.

     SECTION  5.12.  Protection  of  Collateral.  Upon  notice  to the  Borrower
(provided  that if an Event of Default has occurred and is continuing the Lender
need not give any  notice),  the Lender shall have the right at any time to make
any payments and do any other acts the Lender may deem  necessary to protect its
security interests in the Collateral,  including, without limitation, the rights
to satisfy,  purchase,  contest, or compromise any encumbrance,  charge, or lien
which,  in the  reasonable  judgment  of the  Lender,  appears to be prior to or
superior to the security interests granted hereunder,  and appear in, and defend
any action or proceeding  purporting to affect its security interests in, or the
value of, any of the  Collateral.  The Borrower  hereby  agrees to reimburse the
Lender  for all  payments  made  and  expenses  incurred  under  this  Agreement
including  fees,  expenses,   and  disbursements  of  attorneys  and  paralegals
(including  the  allocated  costs of  in-house  counsel)  acting for the Lender,
including  any of the  foregoing  payments  under,  or acts taken to protect its
security  interests  in, any of the  Collateral,  which amounts shall be secured
under this  Agreement,  and agrees it shall be bound by any payment  made or act
taken by the Lender  hereunder  absent the Lender's gross  negligence or willful
misconduct.  The Lender shall have no  obligation  to make any of the  foregoing
payments or perform any of the foregoing acts.

     SECTION 5.13.  Delivery of Items. The Borrower will (a) promptly (but in no
event later than one  Business  Day) after its receipt  thereof,  deliver to the
Lender  any  documents  or  certificates  of title  issued  with  respect to any
property included in the Collateral, and any promissory notes, letters of credit
or instruments  related to or otherwise in connection with any property included
in the  Collateral,  which in any such  case  come  into the  possession  of the
Borrower,  or shall cause the issuer thereof to deliver any of the same directly
to the  Lender,  in each case with any  necessary  endorsements  in favor of the
Lender and (b) deliver to the Lender as soon as available  copies of any and all
press releases and other similar communications issued by the Borrower.

     SECTION 5.14.  Solvency.  The Borrower  shall be and remain  Solvent at all
times.

     SECTION  5.15.  Fundamental  Changes.  The Borrower  shall not (a) amend or
modify its name, unless the Borrower delivers to the Lender thirty days prior to
any such proposed amendment or modification  written notice of such amendment or
modification and within ten days before such amendment or modification  delivers
executed  Uniform  Commercial  Code financing  statements (in form and substance
satisfactory  to the Lender) or (b) merge or  consolidate  with any other entity
without the Lender's  prior  written  consent which shall not be withheld if (i)
the  Borrower is the  survivor of such  merger or  consolidation  and remains in
compliance  with all the terms and conditions of the Loan Documents or any other
survivor of such merger or consolidation assumes all the Obligations, including,
without  limitation,  all of the  Borrower's  payment  obligations,  pursuant to
assignment documentation  acceptable to the Lender in its sole discretion,  (ii)
in the reasonable  judgment of the Lender,  the ability of such surviving entity
to perform  its  obligations  hereunder  is no worse  than that of the  Borrower
immediately before such merger or consolidation, and (iii) such surviving entity
delivers Uniform Commercial Code financing statements (Form UCC-1) duly executed
by the  surviving  entity  (naming the Lender as secured party and the surviving
entity as debtor and in form acceptable for filing in all jurisdictions that the
Lender deems necessary or advisable to perfect the security interests granted to
it hereunder) and, if applicable, termination statements, or other releases duly
filed in all  jurisdictions  that the Lender  deems  necessary  or  advisable to
perfect and  protect  the  priority  of the  security  interests  granted by the
Borrower hereunder).

     SECTION 5.16.  Additional  Requirements.  The Borrower  shall take all such
further  actions and execute all such further  documents and  instruments as the
Lender may  reasonably  request to carry out the intent and  purpose of the Loan
Documents.

immediately  due and  payable  without  necessity  of any  declaration)  without
presentment,  representation,  demand of payment,  or protest,  which are hereby
expressly waived.

     (b) The Lender may take  possession of the Collateral and, for that purpose
may enter,  with the aid and  assistance of any person or persons,  any premises

     (d) The Lender may  exercise in respect of the  Collateral,  in addition to
other  rights and  remedies  provided  for herein (or in any Loan  Document)  or
otherwise  available to it, all the rights and remedies of a secured party under
the  applicable  Uniform  Commercial  Code (the "Code")  whether or not the Code
applies to the affected Collateral and also may (i) require the Borrower to, and
the Borrower  hereby  agrees that it will at its expense and upon request of the
Lender  forthwith,  assemble  all or part of the  Collateral  as directed by the
Lender and make it  available to the Lender at a place to be  designated  by the
Lender that is  reasonably  convenient  to both parties and (ii) without  notice
except as specified  below,  sell the  Collateral  or any part thereof in one or
more  parcels  at public or  private  sale,  at any of the  Lender's  offices or
elsewhere,  for cash,  on credit,  or for future  delivery,  and upon such other
terms as the Lender may deem commercially reasonable.  The Borrower agrees that,
to the extent notice of sale shall be required by law, at least ten days' notice
to the Borrower of the time and place of any public sale or the time after which
any private sale is to be made shall  constitute  reasonable  notification.  The
Lender  shall not be  obligated  to make any sale of  Collateral  regardless  of
notice of sale having  been given.  The Lender may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and

was so adjourned.

     (e) All cash  proceeds  received  by the  Lender in respect of any sale of,
collection  from, or other  realization  upon all or any part of the  Collateral
may, in the discretion of the Lender,  be held by the Lender as collateral  for,
or then or at any time  thereafter  applied  in  whole or in part by the  Lender
against,  all or any part of the  Obligations  in such order as the Lender shall
elect.  Any  surplus  of such  cash  or cash  proceeds  held by the  Lender  and
remaining after the full and final payment of all the Obligations  shall be paid
over to the Borrower or to such other Person to which the Lender may be required
under applicable law, or directed by a court of competent jurisdiction,  to make
payment of such surplus.

permitted by Applicable Law.

     The  undersigned  shall  have the right to prepay  this Note at any time on

prepayment,  the undersigned  shall pay, an amount equal to the present value of

notice of any kind,  and assents to extensions of the time of payment,  release,
surrender or  substitution  of security,  or  forbearance  or other  indulgence,
without  notice.  The  undersigned  agrees to pay all  amounts  under  this Note

     The Payee,  the  undersigned  and any other  parties to the Loan  Documents
intend to contract in strict  compliance with applicable  usury law from time to
time in effect.  In  furtherance  thereof such Persons  stipulate and agree that
none of the terms and provisions  contained in the Loan Documents  shall ever be
construed to create a contract to pay, for the use,  forbearance or detention of
money,  interest in excess of the maximum  amount of  interest  permitted  to be
charged by Applicable Law from time to time in effect.  Neither the  undersigned
nor any present or future  guarantors,  endorsers,  or other  Persons  hereafter
becoming liable for payment of any Obligation  shall ever be liable for unearned
interest  thereon or shall ever be required to pay interest thereon in excess of
the maximum amount that may be lawfully  charged under  Applicable Law from time
to time in effect,  and the provisions of this paragraph  shall control over all
other  provisions  of the Loan  Documents  which may be in  conflict or apparent
conflict  herewith.  The Payee  expressly  disavows  any  intention to charge or
collect excessive unearned interest or finance charges in the event the maturity
of any  Obligation  is  accelerated.  If (a) the maturity of any  Obligation  is
accelerated  for any reason,  (b) any  Obligation is prepaid and as a result any
amounts held to constitute  interest are determined to be in excess of the legal
maximum,  or (c) the Payee or any other holder of any or all of the  Obligations
shall  otherwise  collect  amounts which are  determined to constitute  interest
which would otherwise  increase the interest on any or all of the Obligations to
an amount in excess of that  permitted to be charged by  Applicable  Law then in
effect,  then all sums determined to constitute interest in excess of such legal
limit shall, without penalty, be promptly applied to reduce the then outstanding
principal of the related Obligations or, at the Payee's or such holder's option,
promptly  returned to the undersigned  upon such  determination.  In determining
whether or not the interest  paid or payable,  under any specific  circumstance,
exceeds the maximum amount  permitted  under  Applicable  Law, the Payee and the
undersigned  (and  any  other  payors  thereof)  shall  to the  greatest  extent
permitted under Applicable Law, (i) characterize any non-principal payment as an
expense,  fee or  premium  rather  than  as  interest,  (ii)  exclude  voluntary
prepayments and the effects thereof, and (iii) amortize,  prorate, allocate, and
spread the total amount of interest through the entire contemplated term of this
Note in accordance with the amount  outstanding from time to time thereunder and
the maximum legal rate of interest from time to time in effect under  Applicable
Law in order to lawfully  charge the maximum amount of interest  permitted under
Applicable Law.

     This Note may not be changed, modified or terminated orally, but only by an
agreement  in  writing  signed by the  undersigned  and the Payee or any  holder
hereof.

     The undersigned shall, upon demand, pay to the Payee all costs and expenses
incurred by the Payee (including the fees and disbursements of counsel and other
professionals)  in connection  with the  preparation,  execution and delivery of
this  Note  and  all  other  Loan   Documents,   and  in  connection   with  the
administration, modification and amendment of the Loan Documents, and pay to the
Payee all costs and expenses  (including the fees and  disbursements  of counsel
and other  professionals)  paid or  incurred  by the Payee in (A)  enforcing  or
defending  its rights  under or in respect of this Note or any of the other Loan
Documents, (B) collecting any of the liabilities by the undersigned to the Payee
or otherwise  administering  the Loan  Documents,  (C)  foreclosing or otherwise
collecting upon any collateral and (D) obtaining any legal,  accounting or other
advice in connection with any of the foregoing.

     This  Note  shall  be  binding  upon  the  successors  and  assigns  of the
undersigned and inure to the benefit of the Payee and its successors,  endorsees
and  assigns.  If any term or  provision  of this  Note  shall be held  invalid,
illegal or unenforceable,  the validity of all other terms and provisions hereof
shall in no way be affected thereby.

                           STOCK SUBSCRIPTION WARRANT

                           To Purchase Common Stock of

                          GalaGen, Inc. (the "Company")

                     DATE OF INITIAL ISSUANCE: July 1, 1997

     THIS  CERTIFIES  THAT for  value  received,  TRANSAMERICA  BUSINESS  CREDIT
CORPORATION  or its  registered  assigns  (hereinafter  called the  "Holder") is
entitled  to  purchase  from the  Company,  at any time  during the Term of this
Warrant,  Forty Thousand (40,000) shares of common stock, $.01 par value, of the
Company (the "Common Stock"),  at the Warrant Price,  payable in lawful money of
the United States of America to be paid upon the exercise  hereof.  The exercise
of this Warrant shall be subject to the provisions, limitations and restrictions
herein contained, and may be exercised in whole or in part.

SECTION 1. Definitions.

     For all  purposes  of this  Warrant,  the  following  terms  shall have the
meanings indicated:

     Common  Stock - shall mean and  include  the  Company's  authorized  Common
Stock, $.01 par value, as constituted at the date hereof.

     Exchange Act - shall mean the  Securities  Exchange Act of 1934, as amended
from time to time.

     Securities Act - the Securities Act of 1933, as amended.

     Term of this  Warrant  - shall  mean the  period  beginning  on the date of
initial issuance hereof and ending on June 30, 2002.

         Warrant  Price - $2.50 per share,  subject to  adjustment in accordance
with Section 5 hereof.

     Warrant  Shares - shares of Common Stock  purchased or  purchasable  by the
Holder of this Warrant upon the exercise hereof.

SECTION 2. Exercise of Warrant.

     2.1.  Procedure for Exercise of Warrant.  To exercise this Warrant in whole
or in part (but not as to any  fractional  share of Common  Stock),  the  Holder
shall  deliver to the Company at its office  referred to in Section 12 hereof at
any time and from time to time during the Term of this  Warrant:  (i) the Notice
of Exercise in the form attached hereto,  (ii) cash,  certified or official bank
check  payable  to the  order  of the  Company,  wire  transfer  of funds to the
Company's account,  or evidence of any indebtedness


                                       21


<PAGE>

of the Company to the Holder (or any combination of any of the foregoing) in the
amount of the  Warrant  Price for each  share  being  purchased,  and (iii) this
Warrant.  Notwithstanding any provisions herein to the contrary,  if the Current
Market Price (as defined in Section 5) is greater than the Warrant Price (at the
date of calculation,  as set forth below), in lieu of exercising this Warrant as
hereinabove  permitted,  the Holder may elect to receive  shares of Common Stock
equal to the value (as determined below) of this Warrant (or the portion thereof
being  canceled)  by  surrender  of this  Warrant at the  office of the  Company
referred to in Section 12 hereof, together with the Notice of Exercise, in which
event the  Company  shall  issue to the Holder  that  number of shares of Common
Stock computed using the following formula:

                               CS = WCS x (CMP-WP)
                               ------------------
                                       CMP

Where

          CS   equals the  number of shares of Common  Stock to be issued to the
               Holder

          WCS  equals the number of shares of Common Stock purchasable under the
               Warrant or, if only a portion of the Warrant is being  exercised,
               the portion of the Warrant  being  exercised (at the date of such
               calculation)

          CMP  equals the Current Market Price (at the date of such calculation)

          WP   equals  the  Warrant  Price  (as  adjusted  to the  date  of such
               calculation)

In the event of any  exercise  of the  rights  represented  by this  Warrant,  a
certificate  or  certificates  for the  shares  of  Common  Stock so  purchased,
registered  in the  name of the  Holder  or such  other  name or names as may be
designated  by the Holder,  shall be  delivered  to the Holder  hereof  within a
reasonable time, not exceeding  fifteen (15) days, after the rights  represented
by this  Warrant  shall have been so  exercised;  and,  unless this  Warrant has
expired,  a new Warrant  representing  the number of shares  (except a remaining
fractional  share),  if any,  with respect to which this Warrant  shall not then
have been exercised  shall also be issued to the Holder hereof within such time.
The person in whose name any  certificate  for shares of Common  Stock is issued
upon  exercise of this  Warrant  shall for all purposes be deemed to have become
the  holder  of  record of such  shares  on the date on which  the  Warrant  was
surrendered and payment of the Warrant Price and any applicable  taxes was made,
irrespective  of the date of delivery of such  certificate,  except that, if the
date of such  surrender and payment is a date when the stock  transfer  books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business  on the next  succeeding  date on which the
stock transfer books are open.

     2.2. Transfer Restriction Legend. Each certificate for Warrant Shares shall
bear  the  following  legend  (and any  additional  legend  required  by (i) any
applicable  state  securities  laws and (ii) any securities  exchange upon which
such Warrant  Shares may, at the time of such  exercise,  be listed) on the face
thereof  unless at the time of exercise such Warrant  Shares shall be registered
under the Securities Act:

          "The shares  represented by this  certificate have not been registered
          under the Securities  Act of 1933, as amended,  and may not be sold or
          transferred  in the  absence  of  such  registration  or an  exemption
          therefrom under said Act."

Any  certificate  issued  at any  time  in  exchange  or  substitution  for  any
certificate bearing such legend (except a new certificate issued upon completion
of a  public  distribution  under a  registration  statement  of


                                       22

the securities  represented  thereby) shall also bear such legend unless, in the
opinion of counsel for the holder  thereof  (which  counsel  shall be reasonably
satisfactory to counsel for the Company) the securities  represented thereby are
not, at such time, required by law to bear such legend.

SECTION 3. Covenants as to Common Stock.  The Company  covenants and agrees that
all shares of Common  Stock that may be issued  upon the  exercise of the rights
represented by this Warrant will, upon issuance,  be validly issued,  fully paid
and  nonassessable,  and free from all taxes,  liens and charges with respect to
the issue  thereof.  The Company  further  covenants and agrees that it will pay
when due and payable any and all federal and state taxes which may be payable in
respect  of the  issue of this  Warrant  or any  Common  Stock  or  certificates
therefor  issuable upon the exercise of this  Warrant,  but not capital gains or
other taxes on or measured by the  increase or decrease of net income or loss of
the Holder.  The Company  further  covenants and agrees that the Company will at
all  times  have  authorized  and  reserved,  free  from  preemptive  rights,  a
sufficient  number of shares of Common  Stock to provide for the exercise of the
rights  represented by this Warrant.  The Company  further  covenants and agrees
that if any  shares of  capital  stock to be  reserved  for the  purpose  of the
issuance of shares upon the exercise of this Warrant require  registration  with
or approval of any governmental  authority under any federal or state law before
such shares may be validly issued or delivered  upon exercise,  then the Company
will in good faith and as  expeditiously  as  possible  endeavor  to secure such
registration  or approval,  as the case may be except that the Company shall not
be  required  to  make  any  filings  because  a  holder  of this  warrant  is a
non-accredited  investor.  If and so long as the Common Stock  issuable upon the
exercise of this  Warrant is listed on any  national  securities  exchange,  the
Company will, if permitted by the rules of such  exchange,  list and keep listed
on such exchange,  upon official  notice of issuance,  all shares of such Common
Stock issuable upon exercise of this Warrant.

SECTION 4.  Adjustment of Number of Shares.  Upon each adjustment of the Warrant
Price as  provided  in Section 5, the Holder  shall  thereafter  be  entitled to
purchase,  at the Warrant Price  resulting from such  adjustment,  the number of
shares  (calculated to the nearest tenth of a share) obtained by multiplying the
Warrant Price in effect  immediately  prior to such  adjustment by the number of
shares  purchasable  pursuant  hereto  immediately  prior to such adjustment and
dividing  the  product   thereof  by  the  Warrant  Price  resulting  from  such
adjustment.

SECTION 5.  Adjustment of Warrant  Price.  The Warrant Price shall be subject to
adjustment from time to time as follows:

     (i) If, at any time during the Term of this  Warrant,  the number of shares
of Common Stock  outstanding is increased by a stock dividend  payable in shares
of Common Stock or by a subdivision or split-up of shares of Common Stock, then,
following the record date fixed for the determination of holders of Common Stock
entitled to receive such stock  dividend,  subdivision or split-up,  the Warrant
Price shall be  appropriately  decreased  so that the number of shares of Common
Stock issuable upon the exercise hereof shall be increased in proportion to such
increase in outstanding shares.

     (ii) If, at any time during the Term of this Warrant,  the number of shares
of Common Stock  outstanding  is decreased by a combination  of the  outstanding
shares of Common Stock,  then,  following the record date for such  combination,
the Warrant Price shall  appropriately  increase so that the number of shares of
Common Stock issuable upon the exercise  hereof shall be decreased in proportion
to such decrease in outstanding shares.

     (iii) In case,  at any time  during the Term of this  Warrant,  the Company
shall declare a cash dividend upon its Common Stock payable  otherwise  than out
of earnings or earned surplus or shall distribute to holders of its Common Stock
shares of its capital stock (other than Common Stock), stock or other securities
of other  persons,  evidences  of  indebtedness  issued by the  Company or other
persons,


                                       23


<PAGE>


assets  (excluding  cash  dividends  and  distributions)  or  options  or rights
(excluding options to purchase and rights to subscribe for Common Stock or other
securities of the Company  convertible  into or exchangeable  for Common Stock),
then,  in each such case,  immediately  following  the record date fixed for the
determination  of the holders of Common Stock  entitled to receive such dividend
or distribution,  the Warrant Price in effect  thereafter shall be determined by
multiplying the Warrant Price in effect immediately prior to such record date by
a fraction of which the numerator  shall be an amount equal to the difference of
(x) the  Current  Market  Price of one share of Common  Stock minus (y) the fair
market value (as  determined  by the Board of  Directors  of the Company,  whose
determination  shall be  conclusive)  of the  stock,  securities,  evidences  of
indebtedness,  assets,  options or rights so distributed in respect of one share
of Common  Stock,  and of which the  denominator  shall be such  Current  Market
Price.

     (iv) All  calculations  under this  Section 5 shall be made to the  nearest
cent or to the nearest one-tenth (1/10) of a share, as the case may be.

     (v) For the  purpose of any  computation  pursuant  to this  Section 5, the
Current Market Price at any date of one share of Common Stock shall be deemed to
be the average of the daily closing prices for the 15 consecutive  business days
ending no more than 5 business  days before the day in question (as adjusted for
any stock  dividend,  split,  combination or  reclassification  that took effect
during such 15 business day period). The closing price for each day shall be the
last reported  sales price  regular way or, in case no such reported  sales took
place on such day, the average of the last reported bid and asked prices regular
way, in either case on the principal national  securities  exchange on which the
Common  Stock is listed or  admitted  to trading or as reported by Nasdaq (or if
the Common  Stock is not at the time listed or admitted  for trading on any such
exchange or if prices of the Common  Stock are not  reported by Nasdaq then such
price shall be equal to the average of the last reported bid and asked prices on
such day as  reported  by The  National  Quotation  Bureau  Incorporated  or any
similar  reputable  quotation and reporting  service,  if such  quotation is not
reported by The National Quotation Bureau Incorporated); provided, however, that
if the Common Stock is not traded in such manner that the quotations referred to
in this clause (v) are available for the period required hereunder,  the Current
Market Price shall be  determined in good faith by the Board of Directors of the
Company or, if such  determination  cannot be made,  by a nationally  recognized
independent  investment  banking firm  selected by the Board of Directors of the
Company  (or if such  selection  cannot  be  made,  by a  nationally  recognized
independent  investment  banking  firm  selected  by  the  American  Arbitration
Association in accordance with its rules).

     (vi) Whenever the Warrant Price shall be adjusted as provided in Section 5,
the  Company  shall  prepare  a  statement  showing  the  facts  requiring  such
adjustment and the Warrant Price that shall be in effect after such  adjustment.
The Company shall cause a copy of such statement to be sent by mail, first class
postage  prepaid,  to each  Holder of this  Warrant at its,  his or her  address
appearing on the Company's records. Where appropriate, such copy may be given in
advance and may be included  as part of the notice  required to be mailed  under
the provisions of subsection (viii) of this Section 5.

     (vii)  Adjustments made pursuant to clauses (i), (ii) and (iii) above shall
be made  on the  date  such  dividend,  subdivision,  split-up,  combination  or
distribution,  as the case may be, is made,  and shall  become  effective at the
opening of business on the business day next  following  the record date for the
determination of stockholders entitled to such dividend, subdivision,  split-up,
combination or distribution.

     (viii) In the event the  Company  shall  propose  to take any action of the
types  described in clauses (i),  (ii),  or (iii) of this Section 5, the Company
shall  forward,  at the same time and in the same manner,  to the Holder of this
Warrant  such  notice,  if any,  which the Company  shall give to the holders of
capital stock of the Company.



                                       24


<PAGE>


     (ix) In any case in which the  provisions  of this Section 5 shall  require
that an adjustment shall become effective immediately after a record date for an
event,  the Company may defer until the  occurrence of such event issuing to the
Holder of all or any part of this Warrant  which is exercised  after such record
date and before the  occurrence of such event the  additional  shares of capital
stock issuable upon such exercise by reason of the  adjustment  required by such
event over and above the shares of capital  stock  issuable  upon such  exercise
before giving effect to such adjustment exercise;  provided,  however,  that the
Company shall deliver to such Holder a due bill or other appropriate  instrument
evidencing  such  Holder's  right to receive  such  additional  shares  upon the
occurrence of the event requiring such adjustment.

SECTION 6. Ownership.

     6.1.  Ownership of This Warrant.  The Company may deem and treat the person
in whose  name this  Warrant  is  registered  as the  holder  and  owner  hereof
(notwithstanding  any  notations of  ownership or writing  hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until  presentation of this Warrant for registration of transfer
as provided in this Section 6.

     6.2.  Transfer and  Replacement.  This Warrant and all rights hereunder are
transferable  in whole or in part upon the books of the  Company  by the  Holder
hereof in person or by duly authorized attorney,  and a new Warrant or Warrants,
of the same tenor as this Warrant but  registered in the name of the  transferee
or  transferees  (and in the  name  of the  Holder,  if a  partial  transfer  is
effected)  shall be made and  delivered  by the Company  upon  surrender of this
Warrant duly  endorsed,  at the office of the Company  referred to in Section 12
hereof. Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss,  theft or  destruction,  and, in such case,  of  indemnity or security
reasonably  satisfactory to it, and upon surrender of this Warrant if mutilated,
the Company  will make and deliver a new Warrant of like tenor,  in lieu of this
Warrant;  provided that if the Holder hereof is an instrumentality of a state or
local  government  or  an  institutional   holder  or  a  nominee  for  such  an
instrumentality or institutional holder an irrevocable agreement of indemnity by
such Holder  shall be  sufficient  for all  purposes  of this  Section 6, and no
evidence of loss or theft or destruction shall be necessary.  This Warrant shall
be promptly canceled by the Company upon the surrender hereof in connection with
any  transfer or  replacement.  Holder will not  transfer  this  Warrant and the
rights hereunder except in compliance with federal and state securities laws.

SECTION  7.  Mergers,  Consolidation,   Sales.  In  the  case  of  any  proposed
consolidation or merger of the Company with another entity, or the proposed sale
of all or  substantially  all of its assets to another person or entity,  or any
proposed reorganization or reclassification of the capital stock of the Company,
then, as a condition of such  consolidation,  merger,  sale,  reorganization  or
reclassification, lawful and adequate provision shall be made whereby the Holder
of this Warrant  shall  thereafter  have the right to receive upon the basis and
upon the terms and  conditions  specified  herein,  in lieu of the shares of the
Common Stock of the Company immediately theretofore purchasable hereunder,  such
shares of stock,  securities or assets as may (by virtue of such  consolidation,
merger,  sale,  reorganization  or  reclassification)  be issued or payable with
respect  to or in  exchange  for the  number  of  shares  of such  Common  Stock
purchasable  hereunder  immediately  before such  consolidation,  merger,  sale,
reorganization or reclassification. In any such case appropriate provision shall
be made with  respect to the rights and  interests of the Holder of this Warrant
to the end that the provisions  hereof shall  thereafter be applicable as nearly
as may be, in relation to any shares of stock,  securities or assets  thereafter
deliverable upon the exercise of this Warrant.

SECTION 8. Notice of Dissolution or Liquidation.  In case of any distribution of
the  assets  of  the  Company  in  dissolution  or  liquidation   (except  under
circumstances  when the foregoing  Section 7 shall be  applicable),  the Company
shall give notice thereof to the Holder hereof and shall make no distribution to
shareholders  until the  expiration of thirty (30) days from the date of mailing
of the  aforesaid  notice and, in any case,  the Holder hereof may exercise this
Warrant within thirty (30) days from the date of the giving of such notice,  and
all rights herein granted not so exercised  within such thirty-day  period shall
thereafter become null and void.

SECTION 9. Notice of Extraordinary  Dividends.  If the Board of Directors of the
Company  shall  declare any dividend or other  distribution  on its Common Stock
except out of earned surplus or by way of a stock dividend  payable in shares of
its Common Stock, the Company shall mail notice thereof to the Holder hereof not
less than  thirty  (30) days  prior to the  record  date  fixed for  determining
shareholders


                                       26


<PAGE>



entitled to participate in such dividend or other  distribution,  and the Holder
hereof shall not participate in such dividend or other distribution  unless this
Warrant is exercised prior to such record date. The provisions of this Section 9
shall not apply to distributions made in connection with transactions covered by
Section 7.

SECTION 10.  Fractional  Shares.  Fractional shares shall not be issued upon the
exercise of this Warrant but in any case where the Holder would,  except for the
provisions  of this Section 10, be entitled  under the terms hereof to receive a
fractional share upon the complete exercise of this Warrant,  the Company shall,
upon the  exercise of this  Warrant for the largest  number of whole shares then
called  for,  pay a sum in  cash  equal  to the  excess  of the  value  of  such
fractional share  (determined in such reasonable  manner as may be prescribed in
good faith by the Board of Directors of the Company)  over the Warrant Price for
such fractional share.

SECTION 11.  Special  Arrangements  of the Company.  The Company  covenants  and
agrees that during the Term of this Warrant,  unless  otherwise  approved by the
Holder of this Warrant:

     11.1. Will Reserve Shares.  The Company will reserve and set apart and have
available for issuance at all times, free from preemptive or other  preferential
rights, the number of shares of authorized but unissued Common Stock deliverable
upon the exercise of this Warrant.

     11.2.  Will  Not  Amend  Certificate.   The  Company  will  not  amend  its
Certificate  of  Incorporation  to eliminate as an  authorized  class of capital
stock that class denominated as "Common Stock" on the date hereof.

     11.3.  Will  Bind  Successors.  This  Warrant  shall  be  binding  upon any
corporation  or other  person or entity  succeeding  to the  Company  by merger,
consolidation  or  acquisition  of all  or  substantially  all of the  Company's
assets.

SECTION 12.  Notices.  Any notice or other document  required or permitted to be
given or delivered to the Holder shall be delivered  at, or sent by certified or
registered mail to, the Holder at Transamerica  Technology Finance Division,  76
Batterson Park Road, Farmington,  Connecticut 06032,  Attention:  Assistant Vice

addressed  and  otherwise  delivered  shall be deemed to be given when  actually
received by the addressee.

SECTION 13. No Rights as  Stockholder;  Limitation  of  Liability.  This Warrant
shall not  entitle  the  Holder to any of the  rights  of a  shareholder  of the
Company. No provision hereof, in the absence of affirmative action by the Holder
to purchase shares of Common Stock, and no mere enumeration herein of the rights
or privileges of the Holder,  shall give rise to any liability of the Holder for
the Warrant  Price  hereunder or as a shareholder  of the Company,  whether such
liability is asserted by the Company or by creditors of the Company.

SECTION 14. Law Governing. THE VALIDITY, INTERPRETATION, AND ENFORCEMENT OF THIS
WARRANT SHALL BE GOVERNED BY AND  CONSTRUED IN  ACCORDANCE  WITH THE

FOR IMMEDIATE RELEASE

         GALAGEN INC. INITIATES PHASE II CLINICAL TRIAL WITH DIFFISTAT-G
                       FOR ANTIBIOTIC-ASSOCIATED DIARRHEA


Arden  Hills,  Minn.  -- August 14, 1997 -- GalaGen  Inc.  (Nasdaq:  GGEN) today
announced  that it has  initiated  a  multi-center  Phase II  clinical  trial of
Diffistat-G,(the  Company's  polyclonal  antibody  drug  for  the  treatment  of
antibiotic-associated   diarrhea,  a  life-threatening  illness  caused  by  the
pathogen,  Clostridium difficile (C. difficile).  Principal investigators in the
study include Ciaran Kelly, M.D., Assistant Professor of Medicine, and J. Thomas
LaMont, M.D., Professor of Medicine and Chief,  Gastroenterology  Division, both
of Beth Israel-Deaconess Medical Center, Harvard Medical School, Boston.

Antibiotic-associated  diarrhea  is  a  major  complication  of  broad  spectrum
antibiotic  therapy,  in which  the  normal  bacterial  flora in the  colon  are
suppressed,  permitting  the bacteria C.  difficile  to colonize  the colon.  In
antibiotic-associated  infections,  C. difficile releases toxins that injure the
lining of the colon, causing painful diarrhea. C. difficile affects an estimated
400,000 patients annually in the U.S. and more than one million globally.

"The  initiation of this Phase II clinical  trial  represents a key milestone in
the advancement of Diffistat-G through the clinical  development  process," said
Robert A. Hoerr, M.D., Ph.D., President and CEO of GalaGen. "We believe that the
results  of  this  trial  will  further  define  the  therapeutic  potential  of
Diffistat-G as an effective treatment for antibiotic-associated diarrhea."

Providing an update on the Sporidin-G(TM) clinical development program,  GalaGen
announced  that it has placed the U.S.  Phase II/III  clinical trial in HIV/AIDS
patients  on hold,  citing a  continued  decline in  Cryptosporidium  parvum (C.
parvum) infections due to the current success of anti-AIDS therapies.

"We remain very  positive  about the  clinical  potential of  Sporidin-G  in the
treatment  of C.  parvum  infections  and will  maintain an active IND in case a
clinical  need  reemerges  in the AIDS  population  or we decide to pursue other
indications for the product," Dr. Hoerr stated.  "In the interim,  we will focus
the Company's  resources on other  pharmaceutical  and  nutritional  products in
development.  These  products offer  significant  market  opportunities  and are
receiving substantial interest from potential corporate partners."

GalaGen Inc. is evaluating the  commercial  potential for Sporidin-G in HIV/AIDS
patients in  developing  countries  where there is an ongoing need for promising
products to address  opportunistic  infections.  The Company is also  evaluating
other  potential  indications,  because C.  parvum  continues  to be targeted by
public  health  officials  as a serious  emerging  pathogen  that  causes  acute
diarrhea in normal individuals, particularly in children.

GalaGen Inc. is developing a portfolio of oral  pharmaceutical  products derived
from  its  platform  technology  that  target   life-threatening   and  emerging
pathogens.  In addition to Diffistat-G,  the Company  currently is advancing two
other  polyclonal  antibody  therapeutics.  Candistat-G(TM)  is an oral antibody
product in early clinical  development  for the treatment of thrush or infection
of the throat and oral cavity with the fungus  Candida.  PylorImune-G(TM)  is in
preclinical   development   with  the  Company's   corporate   partner,   Chiron
Corporation.  The  Company  is  utilizing  its  pharmaceutical  and  nutritional
expertise to actively develop proprietary dietary supplements and medical foods.
