         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1997



1.       BASIS OF PRESENTATION

         The accompanying  unaudited  consolidated  financial  statements of the
Company have been  prepared in accordance  with  generally  accepted  accounting
principles  for  interim  financial  information  and  in  accordance  with  the
instructions  to Form 10-Q and Rule  10-01 of  Regulation  S-X and  include  the
accounts  of  DynaGen,   Inc.  and  its  wholly-owned   subsidiaries,   Superior
Pharmaceutical  Company and Able  Laboratories,  Inc.  Accordingly,  they do not
include all information and footnotes required by generally accepted  accounting
principles   for  complete   financial   statement   presentation.   Significant
intercompany balances and transactions have been eliminated in consolidation.

         As of December 31, 1996, the Company  changed from a fiscal year ending
June 30 to a fiscal year ending December 31.

         The results of  operations  for the interim  periods  reported  are not
necessarily  indicative of expected  results for any future interim period for a
full fiscal year. In the opinion of management,  all adjustments  have been made
(consisting only of normal recurring adjustments) which are necessary for a fair
presentation of operating results for the interim periods presented.

         The financial  information included in this report has been prepared in
conformity with the accounting  policies  reflected in the financial  statements
included in the Company's Transition Report on Form 10-K as of December 31, 1996
filed with the Securities and Exchange Commission.

2.       NET LOSS PER SHARE

         Net loss per common share has been computed by dividing the net loss by
the weighted  average  number of shares of common stock  outstanding  during the
periods indicated. The effect of all common stock equivalents have been excluded
from the calculation of the weighted average number of common shares outstanding
since their inclusion would be anti-dilutive.

3.       INVENTORY

         Inventory at June 30, 1997 consists of the following:

         Raw material                       $  500,250
         Work in-process                       165,320
         Finished goods                      8,211,056

                NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

                                   (Continued)



4.       BUSINESS ACQUISITIONS

         On  August  19,  1996,  the  Company  acquired  certain  assets of Able
Laboratories,  Inc.,  consisting  primarily  of  machinery  and  equipment,  raw
materials and finished goods inventory, and other assets of the tablet business.
The assets were  transferred  by the Company to a newly formed and  wholly-owned
subsidiary named Able Laboratories,  Inc. ("Able"). The purchase price consisted
of $550,000 in cash and acquisition costs of $150,000.  The acquisition has been
accounted  for as a purchase.  The Company  allocated  $313,300 of the  purchase
price to  inventory  and  $386,700 to  property  and  equipment.  The results of
operations  related to Able have been  included  with those of the Company since
August 19, 1996.

         On June 18, 1997, the Company acquired all of the outstanding  stock of
Superior   Pharmaceutical   Company   (Superior),   a  distributor   of  generic
pharmaceutical products.

         In exchange  for the common  stock of  Superior,  the Company  paid the
shareholders of Superior $6,250,000 in cash,  $5,000,000 in three year notes and
1,666,667   shares  of  DynaGen's  common  stock  with  a  guaranteed  value  of
$5,000,000.  DynaGen  is  obligated  to  issue  to  the  shareholders  up  to an
additional  1,666,667  shares of its common  stock  after  twelve  months if its
common  stock is not  trading at an  average of at least  $3.00 per share for 10
consecutive  trading  days as  reported  by the  Nasdaq  SmallCap  Market.   If,
immediately following the issuance of the additional 1,666,667 shares, DynaGen's
common stock is not trading at least $1.50 per share,  DynaGen  shall pay to the
shareholders the difference  between $1.50 and the then current trading price of
its  common  stock  for  each  of the  3,333,334  shares  held  by the  Superior
shareholders.

DynaGen is  obligated  to register  the shares  within  eleven  months after the
closing of the acquisition.  The Company also incurred costs of $694,890 related
to the  acquisition  which  have been  capitalized  as  additional  costs of the
acquisition.



                                       13





The shareholders of Superior may also receive certain  incentive  payments based
on  Superior's  performance  during the three  years  following the close of the
acquisition.  Immediately  following  the  closing of the  acquisition,  DynaGen
contributed  additional capital of $1,750,000 to  Superior.

The acquisition has been accounted for as a purchase.  Accordingly,  the results
of  operations  of Superior  have been  included in the  consolidated  financial
statements  since  the  date of  acquisition.  The  preliminary  purchase  price
allocation  was based on the  estimated  fair values at the date of  acquisition
which  resulted  in an excess of  purchase  price  over net assets  acquired  of
$14,294,534,  which is being amortized on a  straight-line  basis over 15 years.
The  preliminary  allocation  is  subject  to change  because  of the  incentive
payments that may be made to certain shareholders and deferred income taxes.


         Unaudited  proforma  consolidated  operating  results for the  Company,
assuming the  acquisition of Able and Superior had been made as of the beginning
of the fiscal year for each of the periods presented, are as follows:

                                  DYNAGEN, INC.

6.     FINANCING OF SUPERIOR ACQUISITION

       The following debt and equity financings were arranged to fund the
Acquisition of Superior:

         (A) DynaGen obtained senior  subordinated  debt financing of $3,000,000
from two private investors.  Interest on the senior  subordinated debt financing
is 13.5%  annually with interest  payable in monthly  installments.  There is no
amortization of the principal amount on the note for the first five years of the
note, and principal is paid upon maturity at the end of five years.  The loan is
made available to DynaGen (as parent) for the acquisition and as working capital
for Superior and is secured by a first-lien  security  interest on the assets of
DynaGen,  a  second-lien  security  interest  on the  assets of  Superior  and a
second-lien interest in the pledge of the Superior Stock. DynaGen also issued to
the investors  warrants to purchase 400,000 shares of Common Stock of DynaGen at
an exercise price per share of $.01  exercisable  for five years.  Under certain
circumstances, the two investors may exchange the warrants to buy DynaGen Common
Stock for warrants to purchase a 15% of  Superior's  Common Stock at an exercise
price per share of $.01  exercisable  until August 31, 2002. In addition,  these
warrants are subject to certain put features under certain circumstances.

         The proceeds  from this  financing  was  allocated to the DynaGen stock
warrants,  based on  their  estimated  fair  value,  $702,000.  This  amount  is
reflected  in the  accompanying  financial  statements  as a  warrant  liability
because  the  warrants  are  subject to a Put and  Substitution  Agreement  (the
Agreement) which gives the holders of the warrants a choice of a cash settlement
under certain  conditions.  The Agreement allows the holders of the Warrants the
right and option to sell the  Warrants to the company  after  three  years,  for
$667,000, and after five years, for $1,500,000.

         If the market value of the shares  issuable  pursuant to the warrant is
equal to or greater than the put value, then the puts cannot be exercised.

         The remaining proceeds from this offering  $2,298,000 were allocated to
the  subordinated  debt. The debt discount of $702,000 will be amortized,  using
the interest method, over the term of the debt.

         (B) DynaGen  obtained  debt  financing  in the form of a bridge loan of
$500,000,  from a private  investor at an interest  rate of 7% per annum and due
September 30, 1997, to

                                       15





be used for the  maintenance of net worth  requirements  for  Superior's  credit
facility,  working capital for operations of DynaGen and the  acquisition.  This
loan is a  non-recourse  obligation  of DynaGen.  Two  founders of DynaGen  have
pledged  1 million  shares  of  DynaGen's  Common  Stock in order to secure  the
obligations  represented  by this bridge loan.  In  connection  with this bridge
loan, the Company has issued 150,000 shares of its unregistered  Common Stock to
Coutts & Co., AG.

         The proceeds from the debt financing  allocated to the common stock was
$150,000  based on the estimated fair value at June 18, 1997. The balance of the
proceeds was allocated to the bridge loan. The debt discount on the bridge loan,
$150,000, is being amortized over the life of the loan.

         (C) DynaGen obtained equity financing in the form of the sale to twelve
accredited  investors of 41,000 shares of DynaGen's Series A Preferred Stock and
warrants to purchase  328,000  shares of Common Stock at an  aggregate  purchase
price of $4,100,000.  The Series A Preferred Stock has a stated dividend of five
dollars ($5.00) per share per annum. DynaGen is obligated to register the shares
of Common Stock  issuable upon  conversion  of the Series A Preferred  Stock and
exercise of the  warrants  within 90 days after the closing of the  Acquisition.
The exercise price of the warrants will be 120% of the average closing bid price
of  DynaGen's  Common Stock as reported by the Nasdaq  SmallCap  Market (or such
other  exchange on which the Common  Stock is then  traded) for the five trading
days  immediately  preceding  the  date on which  the  Securities  and  Exchange
Commission declares effective the registration statement to be filed registering
the shares of Common Stock  issuable  upon  conversion of the Series A Preferred
Stock and exercise of the Warrants. The holders of Series A preferred Stock have
certain rights of first refusal on future equity financings.

         The Series A preferred  stock may be  converted  into common stock at a
conversion  price equal to the lesser of 120% of the average  closing bid price,
as defined  (the Series A Effective  Price) and  discounted  percentages  of the
Series A Effective  Price  ranging  from 80% to 74%,  based on a schedule of the
number of days after the issuance date that the conversion takes place.

         All  shares  of the  Series A  preferred  stock  will be  automatically
converted to common stock two years from the issue date.



                                       16





         (D) DynaGen  obtained equity financing in the form of the sale of 7,500
shares of  DynaGen's  Series B Preferred  Stock and 225,000  shares of DynaGen's
Common Stock at an aggregate  purchase price of $750,000 to a private  investor.
The Series B Preferred  Stock has a stated dividend of seven dollars ($7.00) per
share per annum. Upon liquidation,  the Series B Preferred Stock ranks junior to
the Series A Preferred  Stock.  DynaGen is  obligated  to  register  the 225,000
shares of Common  Stock  issued and the  shares of Common  Stock  issuable  upon
conversion of the Series B Preferred  Stock within 150 days after the closing of
the acquisition.

         The Series B preferred  stock may be  converted  into Common Stock at a
conversion  price equal to the lesser of 125% of the average  closing bid price,
as defined (the "Series B Effective Price") of and discounted percentages of the
Series B Effective  Price  ranging  from 80% to 75%,  based on a schedule of the
number of days after the issuance date that the conversion takes place.

         All  shares  of the  Series B  preferred  stock  will be  automatically
converted to common stock two years from the issued date.


                                       17








7.       NOTES PAYABLE - BANK

         Superior  obtained  a  secured  revolving  line  of  credit  of  up  to
$9,000,000  from  Huntington  National Bank to provide  working  capital for its
general  operations.  The  availability  of advances under the line of credit is
subject  to a  borrowing  base  consisting  of the sum of (1) 80% of  Superior's
eligible accounts  receivable,  as defined,  plus (2) 60% of Superior's eligible
inventory, as defined.

         The  advances  under  the line are  secured  by a  first-lien  security
interest  in all of the assets of Superior  and are  guaranteed  by DynaGen,  as
parent of Superior. Superior may draw on the line of credit until April 5, 1998.
Interest  on  advances  under the line of credit are based on the prime  lending
rate or LIBOR plus 2% (7.8% at June 30, 1997.

                       CONDITION AND RESULTS OF OPERATIONS
          -------------------------------------------------------------

         The Private  Securities  Litigation  Reform Act of 1995  contains  safe
harbor provisions regarding  forward-looking  statements.  Except for historical
information contained herein, the matters discussed in the Liquidity and Capital
Resources  section below contain potential risks and  uncertainties,  including,
without  limitation,  risks  related to the  Company's  ability to  successfully
develop,  test,  produce and market its proposed products;  obtain  governmental
approvals in a timely manner;  identify and attract  marketing  partners to help
commercialize the Company's products;  attract and retain key employees;  obtain
meaningful  patent  protection  or  otherwise  over  the  Company's  proprietary
technology;  protect itself from product liability risks or limitations  imposed
due to potential  health care reform;  raise capital for future  operations  and
commercialization  of its  products;  integrate  the products and  personnel the
Company  acquired  in the  acquisition  of  Able  Laboratories,  Inc.  ("Able"),
Superior  Pharmacutical  Company ("Superior") and any future  acquisitions;  and
successfully respond to technological changes in the marketplace.  Specifically,
regulatory approvals of the Company's products are subject to factors beyond the
Company's control, and there can be no assurance that such approvals will not be
delayed  or  ultimately  denied.  The  Company  will need to  attract  marketing
partners in order to exploit its  products,  and there can be no assurance  that
the  Company  will  be  successful  in  attracting  such  partners.   Additional
information  on potential  factors  which could affect the  Company's  financial
results are included in the Company's  public  filings with the  Securities  and
Exchange  Commission,  including without limitation its Form 10-K for the period
ended December 31, 1996.


                              RESULTS OF OPERATIONS


RECENT ACQUISITIONS

         On August 19,  1996,  the  Company  acquired  the tablet  manufacturing
business of Able, a generic pharmaceutical product subsidiary of Alpharma,  Inc.
On June  18,  1997,  the  Company  acquired  all of the  outstanding  shares  of
Superior, a distributor of generic pharmaceutical  products.  These acquisitions
have been accounted for using the "purchase" method of accounting.  As a result,
the results of  operations  for the three and six month  periods  ended June 30,
1997 reflect a full three and six months of operations,  respectively, for Able,
and reflect  twelve days of operations for Superior for the three and six months
ended June 30,  1997.  The  results of  operations  for the three and six months
ended June 30, 1996 do not reflect any operations of Able or Superior.


                     THREE-MONTH PERIOD ENDED JUNE 30, 1997
          AS COMPARED WITH THE THREE-MONTH PERIOD ENDED JUNE 30, 1996

         Revenues  in the second  quarter of the year  ending June 30, 1997 were
$1,280,000  versus  $95,000  for the  second  quarter of the year ended June 30,
1996.  This  increase of  $1,185,000 is primarily the result of product sales by
the  Company's  wholly-owned  generic  pharmaceutical  subsidiaries,   Able  and
Superior.

         Cost of sales exceeds  product  sales for the second  quarter of Fiscal
1997 due to the low  production  levels at Able  during  the  second  quarter of
Fiscal  1997 which did not support  fixed  manufacturing  costs  required at the
facility.

         Research and development expenses for the second quarter of Fiscal 1997
were $1,159,000 versus $1,230,000 for the same period as Fiscal 1996, a decrease
of $71,000.  This  decrease is  partially  to offset an increase in  therapeutic
product  development  costs of $900,000.  Research and  development  efforts are
primarily  attributable  to the  Company's  breast biopsy  technology  and other
technologies  in an early  stage of  development.  In  addition,  the Company is
expending development efforts towards generic pharmaceuticals.

         Selling,  general and administrative expenses for the second quarter of
Fiscal 1997 were $1,067,000  versus $616,000 for the same period as Fiscal 1996,
and increase of $45,000. This increase is primarily  attributable to acquisition
and business  development  costs and the inclusion,  in Fiscal 1997, of selling,
general and administrative costs of the Company's subsidiary  operations at Able
and Superior.

         Investment  income  decreased by $130,000  from $147,000 to $17,000 for
the second quarter of Fiscal 1997 as compared to the same period as Fiscal 1996,
respectively,  as the Company had less funds  available for  investment.  In the
second quarter of 1997, the Company  incurred  interest  expense of $102,000 and
amortized debt financing costs of $18,000 associated with debt financing for the
Superior acquisition.



                      SIX-MONTH PERIOD ENDED JUNE 30, 1997
           AS COMPARED WITH THE THREE-MONTH PERIOD ENDED JUNE 30, 1996

         Revenues  for the six months ended June 30, 1997  ("Fiscal  1997") were
$1,834,000  versus  $223,000  for the six months  ended June 30,  1996  ("Fiscal
1996").  This  increase  of  $1,611,000  is  primarily  the  result  of  generic
pharmacuetical  product sales by the Company's wholly-owned  subsidiaries,  Able
and Superior.

         Cost of sales exceeded  product sales for the first half of Fiscal 1997
since  production  at Able  during the first half of Fiscal 1997 did not support
the minimum level of fixed manufacturing costs required at the facility.

            Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS
          -------------------------------------------------------------

         Research  and  development  expenses  for the first half of Fiscal 1997
were $1,647,000 versus $2,081,000 for the same period as fiscal 1996, a decrease
of $434,000. Research and developement efforts are primarily attributable to the
Company's breast biopsy  technology and other  technologies in an early stage of
development.  In  addition,  product  development  efforts  towards  new generic
pharmaceuticals.

         Selling,  general  and  administrative  expenses  for the first half of
Fiscal 1997 were $2,249,000 versus $1,496,000 for the same period as Fiscal 1996
an increase of $753,000.  Selling, general and administrative expenses increased
in the following areas:  product  marketing and support - $108,000 (the increase
in product  marketing and support is attributable  to marketing  efforts for the
Company's of NicCheck(R)  Iproduct,  public relations - $22,000 patent expense -
$57,000.  These  increases  were  offset by a net  decrease of $168,000 in other
operating  expenses  primarily related to acquisitions and business  development
project.

         Investment  income  decreased by $147,000 from $256,000 to $109,000 for
the six months  ended June 30, 1997 as compared to the six months ended June 30,
1996 1996, respectively,  as the Company had less funds available for investment
during the six  months  ended June 30,  1997.  In the six months  ended June 30,
1997,  the Company  incurred  interest  expense of $116,000 and  amortized  debt
financing  costs of $18,000 both  associated with private debt financing for the
Superior acquisition.

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

                         LIQUIDITY AND CAPITAL RESOURCES

         As of June 30, 1997, the Company had working capital of $324,646 versus
working  capital  of  $5,502,295  at  December  31,  1996.  Cash and  investment
securities  were $576,881 at June 30, 1997 as compared to $5,117,000 at December
31,  1996.  Working  capital  and cash  were used  primarily  for  research  and
development and to fund Able and its operations during the quarter.

         On June 18, 1997 the Company acquired all of the outstanding  shares of
Superior (the "Superior Acquisition"),  a privately-held  distributor of generic
pharmaceutical  products,  for  purchase  price of $ 6.25  million  in cash,  $5
milliom in three-year  notes and 1,666,667 shares of the Company's Common Stock.
The  shareholders  may also receive  certain cash  incentive  payments  based on
Superior's  performance  during  the  three  years  following  the  close of the
transaction.  In addition,  the Company  assumed the existing  debt of Superior,
consisting  principally  of an  asset-based  line of credit and trade  payables.
Immediately  following  the  closing of the  Superior  Acquisition,  the Company
contributed $1.75 million to the working capital of Superior.

         The Company has incurred  significant losses since inception.  To date,
the Company has financed current operations primarily through private and public
sale of equity as well as the private sale of dept. In August 1997,  the Company
raised  approximately  $150,000  through  the private  sale of its  equity.  The
Company is presently negotiating the sale to a third party of an additional $3.0
million  of its  equity.  If the  Company  is able  to  secure  this  financing,
management  anticipates that the available working capital will be sufficient to
fund current level of  operations,  including the Able and Superior  businesses,
through June 1998. There can be no assurance,  however, that the Company will be
able to secure  this  financing  or that such  financing  will be  available  on
favorable  terms.  The  survival of the Company is  dependent  on its ability to
obtain this and additional  financing and to generate  revenue from sales of its
products. If the Company is usable to obtain additional  financing,  the Company
will be unable to maintain its current level of operations  and will be required
to reduce or eliminate most expenditures relating to its business.

         In order to finance the Superior Acquisition,  the Company obtained (i)
senior  subordinated  debt  financing  of $3.0  million,  (ii) a bridge  loan of
$500,000 and (iii) equity financings totalling $4.85 million.

                   LIQUIDITY AND CAPITAL RESOURCES (Continued)

         While the acquisition of Able has increased the Company's revenues, the
acquisition has also increased costs and expenses,  capital expenditures and net
cash used for operating activities.  The Company intends to fund Able operations
until it becomes  self-supporting.  The Company  continues to pursue  additional
sources of capital in order to fund the growth of the Able generic drug business
and its product development  efforts.  The Able financing may take the form of a
line of credit or equipment notes or leases.  There can be no assurance that the
Company will be able to secure additional financing for the Able business or its
continued  product  development  efforts or that  financing will be available on
favorable  terms. If the Company is unable to obtain such additional  financing,
the  Company's  ability to maintain  its current  level of  operations  would be
materially and adversely  affected and the Company will be required to reduce or
eliminate certain expenditures,  including its research and development activity
with respect to certain proposed products.

                          COMMON STOCK PURCHASE WARRANT


         DYNAGEN, INC., a Delaware corporation (the "COMPANY"), hereby certifies
that, in  consideration  of the services being  performed by Kali  Laboratories,
Inc.  ("KALI")  pursuant to the  Product  Development  Agreement  dated the date
hereof  (the  "DEVELOPMENT  AGREEMENT"),  Kali is  entitled,  subject  to and in
accordance  with the  terms set  forth  below,  to  purchase  from the  Company,
commencing  on the date  hereof,  at any time or from  time to time  before  the
Expiration Date, 500,000 fully paid and  non-assessable  shares of Common Stock,
$.01 par value,  of the Company,  at an exercise  price per share equal to $.05.
Such exercise  price per share as adjusted from time to time as herein  provided
is referred to herein as the "EXERCISE PRICE".  The number and character of such
shares of Common  Stock and the  Exercise  Price are  subject to  adjustment  as
provided  herein.  THIS WARRANT IS EXERCISABLE IN  INSTALLMENTS,  SUBJECT TO THE
SATISFACTION OF CERTAIN CONDITIONS AS SET FORTH IN SECTION 1.3 BELOW. NO PORTION
OF THIS WARRANT MAY BE EXERCISED UNLESS SUCH CONDITIONS HAVE BEEN SATISFIED WITH
RESPECT TO THE CONDITIONS REGARDING EXERCISABILITY.

         As used  herein  the  following  terms,  unless the  context  otherwise
requires, have the following respective meanings:

         (a)  The  term  "COMPANY"  shall  include  DynaGen,  Inc.,  a  Delaware
corporation,  and any corporation  which shall succeed or assume the obligations
of the Company hereunder.

         (b) The term "COMMON  STOCK"  includes (a) the Company's  Common Stock,
$.01 par value per share,  as  authorized,  (b) any other  capital  stock of any
class or classes  (however



                                      -2-


designated)  of the Company,  authorized  on or after such date,  the holders of
which shall have the right, without limitation as to amount, either to all or to
a share of the balance of current dividends and liquidating  dividends after the
payment of dividends and distributions on any shares entitled to preference, and
the  holders of which shall  ordinarily,  in the  absence of  contingencies,  be
entitled  to vote for the  election of a majority  of  directors  of the Company
(even though the right so to vote has been  suspended by the happening of such a
contingency),  (c) any  other  securities  into  which or for  which  any of the
securities  described in (a) or (b) may be converted or exchanged  pursuant to a
plan of recapitalization,  reorganization,  merger, sale of assets or otherwise,
or the conversion of promissory notes or other obligations of the Company.

         (c) The term "OTHER  SECURITIES" refers to any stock (other than Common
Stock) and other  securities  of the Company or any other person  (corporate  or
otherwise)  which the holder of this  Warrant at any time shall be  entitled  to
receive,  or shall have received,  on the exercise of the Warrant, in lieu of or
in  addition  to Common  Stock,  or which at any time shall be issuable or shall
have been  issued in exchange  for or in  replacement  of Common  Stock or Other
Securities pursuant to Sections 3 or 4 or otherwise.

         (d) The term  "EXPIRATION  DATE" shall mean the earlier to occur of (i)
the termination of the Development  Agreement at a time where (a) no shares have
become  exercisable  pursuant  to Section  1.3 below or (b) any shares that have
become  exercisable  have been  exercised  by the holder of this Warrant or (ii)
5:00 p.m.,  Eastern Daylight Savings Time, on April 29, 2010. By way of example,
to the extent the  Development  Agreement is terminated  prior to April 29, 2010
and shares  have  become  exercisable  pursuant  to  Section  1.3 (but not fully
exercised at the time of  termination),  the "Expiration  Date" shall mean April
29, 2010.  Furthermore,  to the extent the  Development  Agreement is terminated
prior to April 29,  2010 and no  shares  have  become  exercisable  pursuant  to
Section 1.3, or any shares that have become  exercisable  have been exercised in
full,  then in  either  case,  the  "Expiration  Date"  shall  mean the date the
Development Agreement is terminated.

         (e) The term "ANDA" means Abbreviated New Drug Application and the term
"FDA" means the United States Food and Drug Administration.

         1.       EXERCISE OF WARRANT.

                  1.1. FULL  EXERCISE.  This Warrant may be exercised in full by
the holder hereof by surrender of this Warrant, with the form of subscription at
the end hereof duly  executed by such  holder,  to the Company at its  principal
office,  accompanied by payment,  in cash or by certified or official bank check
payable to the order of the Company,  in the amount  obtained by multiplying the
number of shares of Common Stock for which this Warrant is then  exercisable  by
the Exercise Price then in effect.

                  1.2. PARTIAL  EXERCISE.  This Warrant may be exercised in part
by surrender of this Warrant in the manner and at the place  provided in Section
1.1 except that the amount payable by the holder on such partial  exercise shall
be the amount  obtained by multiplying  (a) the number of shares of Common Stock
designated  by the  holder  in the  subscription  at the end  hereof  by (b) the




                                      -3-


Exercise Price then in effect.  On any such partial  exercise the Company at its
expense  will  forthwith  issue and  deliver  to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may  request,  calling in the  aggregate  on the face or faces  thereof  for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.

                  1.3.  CONDITIONS  REGARDING  EXERCISABILITY.  This  Warrant is
exercisable  only upon the satisfaction of certain  conditions,  and unless such
conditions  are  satisfied,  only that  portion  of this  Warrant  for which the
conditions  have been  previously  satisfied  may be exercised at any time.  The

                  1.4.  CASHLESS  EXERCISE  FEATURE -- RIGHT TO CONVERT  WARRANT
INTO COMMON  STOCK.  (a) In addition to and without  limiting  the rights of the
Warrantholder under the terms of this Warrant,  the Warrantholder shall have the
right (the  "CONVERSION  RIGHT") to convert this Warrant or any portion  thereof
into shares of Common Stock as provided in this Section at any



                                      -4-


time or from time to time prior to its expiration,  subject to the  restrictions
set forth in paragraph (c) hereof.  In lieu of exercising this warrant for cash,
the holder may elect to  surrender  this warrant for  conversion  and to receive
shares of Common Stock equal to the value of this Warrant (or the portion  being
cancelled,  surrendered  and  converted)  by  surrender  of this  Warrant to the
Company  together  with notice of such  election.  Upon such event,  the Company
shall  issue to the  holder a number  of shares of the  Company's  Common  Stock
computed by using the following formula:

                             X EQUALS Y (A MINUS B)
                                     --------------
                                           A

Where:     X = The number of shares of Common Stock to be issued to the holder;
           Y = The  number  of shares of Common  Stock  purchasable  under  this
           Warrant;
           A = The "Fair Market Value" of one share of the Common Stock; and
           B = The Exercise Price of the Warrant (as adjusted to the date of the
           calculation).

         Upon  exercise of the  Conversion  Right with  respect to a  particular
number of shares  subject to this  Warrant,  the  Company  shall  deliver to the
Warrantholder, without payment by the Warrantholder of any exercise price or any
cash or other consideration,  that number of shares of Common Stock equal to the
number  computed  using  the above  formula.  Notwithstanding  anything  in this
Section to the contrary,  the Conversion  Right cannot be exercised with respect
to a number  of  Converted  Warrant  Shares  having  a value  below  $1,000.  No
fractional  shares shall be issuable upon exercise of the Conversion  Right, and
if the number of shares to be issued in accordance with the foregoing formula is
other than a whole  number,  the Company  shall round down to the nearest  whole
number the total number of shares to be issued.

         (b) The Conversion  Right may be exercised by the  Warrantholder by the
surrender of this Warrant at the principal office of the Company together with a
written statement specifying that the Warrantholder  thereby intends to exercise
the  Conversion  Right and  indicating  the number of shares of Common  Stock or
authorized  Common Stock subject to this Warrant which are being  surrendered in
exercise of the  Conversion  Right.  Such  conversion  shall be  effective  upon
receipt by the  Company of this  Warrant  together  with the  aforesaid  written
statement,  or on such  later  date as is  specified  therein  (the  "CONVERSION
DATE"), but not later than the Expiration Date.

         (c) For purposes of this Section, the "FAIR MARKET VALUE" of a share of
Common Stock or authorized Common Stock as of the Conversion Date shall mean:

                  (i) if the  Company's  Common  Stock  is  then  traded  on any
nationally-recognized  stock exchange or quoted on the Nasdaq National Market or
SmallCap Market,  the average of the closing sale prices for the 20 trading days
preceding the Conversion Date, as reported by such exchange or system;

                  (ii) if the  Company's  Common  Stock  is then  traded  on the
over-the-counter market, the average of the closing bid and closing asked prices
for the 30 trading days preceding the  Conversion  Date, as reported in The Wall
Street Journal or by any market maker; or



                                      -5-


                  (iii)  if  quotations  for  the  Company's   Common  Stock  or
authorized  Common  Stock is not readily  available  as set forth in (i) or (ii)
above, then as determined in good faith by the Company's Board of Directors upon
a review of all relevant factors,  including,  without limitation,  the price at
which  shares of the  Company's  Common Stock or  authorized  Common Stock could
reasonably be expected to be sold in an arms-length transaction, for cash, other
than on an  installment  basis,  to a person not employed by,  controlled by, in
control of or under common control with the Company,  which determination by the
Board of Directors shall give due consideration to recent transactions involving
shares of the Common Stock or  authorized  Common  Stock,  if any,  revenues and
earnings of the Company to the date of such  determination  (if any),  projected
revenues and earnings of the Company, the effect of the transfer restrictions to
which the shares are subject  under law, the absence of a public  market for the
Common Stock or authorized  Common Stock, and such other matters as the Board of
Directors deems pertinent. Such determination by the Board of Directors shall be
conclusive and binding.

         2. DELIVERY OF STOCK  CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
thirty (30) days thereafter,  the Company at its expense  (including the payment
by it of any applicable  issue taxes) will cause to be issued in the name of and
delivered to the holder  hereof,  or as such holder (upon payment by such holder
of any applicable  transfer taxes) may direct, a certificate or certificates for
the number of fully  paid and  non-assessable  shares of Common  Stock (or Other
Securities)  to which such holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction  multiplied by the then current  market value of one
full share.

         3.       ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER.

                  3.1.  REORGANIZATION,  CONSOLIDATION OR MERGER. In case at any
time or from time to time,  the Company shall (a) effect a  reorganization,  (b)
consolidate  with or merge into any other person or entity,  or (c) transfer all
or  substantially  all of its capital  stock,  properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then, in each such case,  the holder of this Warrant,  on the exercise
hereof as  provided  in  Section 1 at any time  after the  consummation  of such
reorganization,   consolidation   or  merger  or  the  effective  date  of  such
dissolution,  as the case may be,  shall  receive,  upon the proper and rightful
exercise  of this  Warrant,  in lieu of the Common  Stock (or Other  Securities)
issuable on such exercise prior to such consummation or such effective date, the
stock and other  securities and property  (including  cash) to which such holder
would have been  entitled  upon such  consummation  or in  connection  with such
dissolution,  as the case may be, if such holder had so exercised  this Warrant,
immediately  prior  thereto,  all subject to further  adjustment  thereafter  as
provided in Sections 4 and 5.

                  3.2.  CONTINUATION OF TERMS. Upon any corporate event referred
to in this Section 3, this Warrant  shall  continue in full force and effect and
the terms hereof shall be applicable to the shares of stock and Other Securities
and property  receivable on the exercise of this Warrant after the  consummation
of such  reorganization,  consolidation or merger, as the case may be, and shall
be binding upon the issuer of any such stock or other securities.




                                      -6-



         4. ADJUSTMENTS FOR STOCK DIVIDENDS AND STOCK SPLITS.  In the event that
the Company shall (i) issue additional  shares of the Common Stock as a dividend
or  other   distribution  on  outstanding   Common  Stock,  (ii)  subdivide  its
outstanding  shares of Common Stock, or (iii) combine its outstanding  shares of
the Common Stock into a smaller  number of shares of the Common Stock,  then, in
each such event, the Exercise Price shall,  simultaneously with the happening of
such event, be adjusted by multiplying  the then prevailing  Exercise Price by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately prior to such event (calculated assuming the conversion
or exchange of all outstanding shares of convertible or exchangeable  securities
of the Company which are convertible or exchangeable  into, or exercisable  for,
shares of Common  Stock)  and the  denominator  of which  shall be the number of
shares of Common  Stock  outstanding  immediately  after such event  (calculated
assuming the conversion or exchange of all outstanding  shares of convertible or
exchangeable  securities of the Company which are  convertible  or  exchangeable
into, or exercisable  for, shares of Common Stock),  and the product so obtained
shall thereafter be the Exercise Price then in effect. The Exercise Price, as so
adjusted,  shall be  readjusted  in the same  manner upon the  happening  of any
successive  event or events  described  herein in this  Section 4. The holder of
this Warrant shall thereafter,  on the exercise hereof as provided in Section 1,
be  entitled  to receive  that number of shares of Common  Stock  determined  by
multiplying  the number of shares of Common Stock which would otherwise (but for
the provisions of this Section 4) be issuable on such exercise, by a fraction of

entitled  to  receive  any  dividend  or  other  distribution,  or any  right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or

         9.   REPLACEMENT  OF  WARRANT.   On  receipt  of  evidence   reasonably

         10.  WARRANTHOLDER  NOT DEEMED  STOCKHOLDER;  RESTRICTIONS ON TRANSFER.
This Warrant is issued upon the following  terms, to all of which each holder or
owner hereof by the taking hereof consents and agrees:

         (a) No holder of this Warrant  shall,  as such, be deemed the holder of
      Common  Stock  that  may at any time be  issuable  upon  exercise  of this
      Warrant for any purpose whatsoever, nor shall anything contained herein be
      construed  to confer  upon such  holder,  as such,  any of the rights of a
      stockholder of the Company until such holder shall have  delivered  formal
      notice to the Company of an intention to exercise this  Warrant,  tendered
      promptly  the  consideration   required  for  exercise  (whether  cash  or
      securities), exercised the Warrant, and been issued shares of Common Stock
      in accordance with the provisions hereof.

         (b)  Neither  this  Warrant  nor any shares of Common  Stock  purchased
      pursuant to this Warrant shall be registered  under the  Securities Act of
      1933, as amended (the  "SECURITIES  ACT") and applicable  state securities
      laws.  Therefore,  the Company may require, as a condition of allowing the
      transfer or exchange of this  Warrant or such  shares,  that the holder or
      transferee of this Warrant or such shares,  as the case may be, furnish to
      the Company an opinion of counsel  acceptable to the Company to the effect
      that such transfer or exchange may be made without  registration under the
      Securities  Act and applicable  state  securities  laws. The  certificates
      evidencing  the  shares of Common  Stock  issued  on the  exercise  of the
      Warrant  shall bear a legend to the effect  that the shares  evidenced  by
      such  certificates  have not been registered  under the Securities Act and
      applicable state securities laws.

         (c) This Warrant is not transferable or assignable to any party without
      the prior written consent of the Company, and accompanied by an opinion of
      counsel  satisfactory  to the Company  that such  transfer is  permissible
      under applicable law.

         11. NOTICES.  All notices and other  communications from the Company to
the holder of this  Warrant  shall be mailed by (i) first  class  mail,  postage
prepaid,  (ii) electronic  facsimile  transmission,  or (iii) express  overnight
courier  service,  at such address as may have been  furnished to the Company in
writing by such  holder or,  until any such holder  furnishes  to the Company an
address, then to, and at the address of, the last holder of this Warrant who has
so furnished an address to the Company.

         12.  MISCELLANEOUS.  This  Warrant  and any term hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Warrant and the shares of Common Stock  underlying this Warrant
shall be construed and enforced in  accordance



                                      -9-


with and  governed  by the laws of the  State of  Delaware.  The  invalidity  or
unenforceability  of any provision hereof shall in no way affect the validity or
enforceability of any other provision.

                           COMMERCIAL LEASE AGREEMENT

THIS LEASE  AGREEMENT  is made and  entered  into as of the date set forth below
between SPC PROPERTIES  LIMITED,  and Ohio limited liability company,  hereafter
referred to as "Lessor" and SUPERIOR PHARMACEUTICAL COMPANY, an Ohio corporation
hereinafter referred to as "Lessee":

                                   WITNESSETH

1.  LEASE  PREMISES:  In  consideration  of the  rents,  terms,  provisions  and
covenants of this Lease,  Lessor hereby leases,  lets, and demises to Lessee the
following described premises:

         Approximately 37,323 square feet  office/warehouse  building (Building)
         comprising 100% of Lessor's building (Lessee's  Percentage) situated on
         a 6.93 +/- acre parcel located at 1385 Kemper Meadow Drive, in the City
         of Forest Park,  Hamilton County,  Ohio, and being further described as
         follows:

         Lot No. 3 of Kemper Meadow Business Center, Block "B", recorded in Plat
         Book 312, Page 36, of the Hamilton County, Ohio Plat Records, and being
         subject to all legal highways, easements and restrictions of record.

2. INITIAL TERM: Subject to and upon the conditions set forth below, the term of
this  Lease  shall   commence  upon  issuance  of  a  certificate  of  occupancy
("Commencement  Date").  The Lease shall  terminate on the last day of the 241st
month thereafter.

3. RENT:  (a) BASE RENT:  Lessee agrees to pay monthly as Base Rental during the
term of this Lease the sums as indicated on the  attached  "Base Rent  Schedule"
(Exhibit B), which amounts shall be payable to Lessor at the address shown below
on the first day of the month. One monthly  installment of rent shall be due and
payable on the day of  execution  of this Lease by Lessee for the first  month's
rent and a like  monthly  installment  shall be due and payable on or before the
first day of each calendar month, as indicated on the Rent Schedule,  during the
demised term;  provided,  that if the "Commencement Date" should be a date other
than the first day of a calendar month, the monthly rental set forth above shall
be pro-rated to the end of that calendar month, and all succeeding  installments
of rent shall be payable on or before the first day of each succeeding  calendar
month during the demised term. Lessee shall pay, as additional rental, all other
sums due under this Lease.

         (b) INSURANCE  PREMIUMS:  Lessor shall provide and Lessor shall pay for
the All Risk Fire and Extended Coverage  Insurance for the Building with loss of
rent endorsement. However, at Lessee's option and subject to Lessor's review and
approval as to form,  content  and  carrier,  Lessee may  provide  the  Building
insurance  to  Lessor  at  Lessee's  expense.  The  costs  associated  with said
insurance  coverage  shall be  included  in the Base  Rent as  indicated  on the
attached "Base Rent Schedule" (Exhibit B). If, however,  the lessee pays for the
cost of the  insurance  then the lessee shall  receive a credit on the Base Rent
for the actual amount paid.









                                      -2-

         (c) REAL ESTATE TAX: The total rental to be paid under this Lease shall
also  include  all real  estate  taxes  and  assessments  levied  on the  Leased
Premises.  Such  payments  be  included  in the Base  Rent as  indicated  on the
attached "Base Rent Schedule' (Exhibit B).

         (d)  SERVICE   CHARGE:   Other   remedies   for   nonpayment   of  rent
notwithstanding,  if the monthly  rental payment is not received by Lessor or if
any other  payment  due Lessor by Lessee is not  received by Lessor on or before
the fifth (5th) day after it is due, a service  charge of five  percent  (5%) of
such past due amount  shall  become due and payable in addition to such  amounts
owed under this Lease.

It is the Lessee's  responsibility to pay on a timely basis all costs associated
with the use and  occupancy of the Leased  Premises  including , but not limited
to,  all taxes,  other  than Real  Estate  Taxes and  assessments,  maintenance,
repairs, grounds keeping and snow removal.

4. USAGE:  Lessee  warrants and  represents  to Lessor that the Leased  Premises
shall  be  used  and  occupied   only  for  the  purposes  of  the  "Lessee"  as
office/warehouse  space.  Lessee shall occupy the Leased  Premises,  conduct its
business and control its agents, employees,  invitees and visitors in such a way
as is lawful,  reputable and will not create any nuisance or otherwise interfere
with,  annoy or disturb any property owner in Kemper Meadow  Business  Center in
its normal  business  operations  or Lessor in its  management  of the Premises.
Lessee  shall not  commit,  or suffer to be  committed,  any waste on the Leased
Premises.

5. INSURANCE: Use of Premises. Lessee shall not permit the Leased Premises to be
used in any way which could be extra  hazardous  on account of fire or otherwise
which  would in any way  increase  or  render  void the  fire  insurance  on the
Building or any part  thereof or any  contents in the  Building  belonging to or
used by Lessor.  If at any time during the term of this Lease the State Board of
Insurance  or other  insurance  authority  disallows  any of Lessor's  sprinkler
credits or imposes an  additional  penalty or  surcharge  in Lessor's  insurance
premiums because of Lessee's original or subsequent  placement or use of storage
racks or bins,  method of storage or nature of Lessee's  inventory  or any other
act of  Lessee,  Lessee  agrees to pay as  additional  rental  the  increase  in
Lessor's insurance premiums.

         Lessee shall carry, at its expense, liability insurance on the Premises
throughout  the Lease Term covering both Lessee and Lessor as named insureds and
if Lessor elects, any owner and/or Lessee of the land upon which the building is
located, as additional named insured,  with terms and companies  satisfactory to
Lessor  and  having a combined  single  limit,  providing  both  bodily  injury,
including death resulting therefrom, and property damage coverage, to the extent
of $2,000,000.00, arising out of the Ownership, maintenance or use of the Leased
Premises. Lessee shall also carry insurance against fire and such other risks as
are from time to time included in standard extended coverage insurance, insuring
the full  replacement  cost of all  leasehold  improvements  paid for by Lessee,
including  wall  coverings,  carpeting,  furnishings  and  equipment.  All  such
policies  shall be cancelable  only upon ten (10) days prior  written  notice to
Lessee and Lessor.  Prior to the Commencement  Date and within fifteen (15) days
prior to the  expiration of each such policy,  Lessee shall furnish  Lessor with
copies of such policies or  certificates  evidencing  that such  insurance is in
full force and effect and stating the terms thereof.








                                      -3-

6. UTILITY SERVICE:  Lessor shall provide the normal utility service  connection
into the Leased  Premises as indicated on approved  construction  plans.  Lessee
shall pay the cost of all utility services,  including,  but not limited to, all
charges for gas, water and electricity used on the Leased Premises. Lessee shall
pay all costs caused by Lessee introducing  excessive pollutants or solids other
than human waste into the sanitary  sewer system,  including  permits,  fees and
charges  levied  by any  governmental  subdivision  for any such  pollutants  or
solids.  Lessee shall be responsible for the installation and maintenance of any
dilution tanks, settling tanks, sewer sampling devices, sand traps, grease traps
or similar  devices  as may be  required  by any  governmental  subdivision  for
Lessee's use of the sanitary  sewer system.  Lessor shall not be required to pay
for any  utility  services,  supplies  or upkeep in  connection  with the Leased
Premises.

7. REPAIRS AND MAINTENANCE:  (a) Lessor's Obligations Unless otherwise expressly
provided, Lessor shall not be required to make any improvements, replacements or
repairs of any kind or character to the Leased  Premises during the term of this
Lease  except such repairs as are set forth in this  subparagraph.  Lessor shall
maintain only the foundation and the structural  soundness of the roof, slab and
exterior walls (excluding all windows,  window glass, plate glass and all doors)
of the  Building in good repair and  condition  except for  reasonable  wear and
tear.  Lessor  will  pass  through  any  manufacturing  warranties  on  building
components  for benefit of Lessee.  Lessee  shall  repair and pay for any damage
caused by the negligence or default of Lessee or Lessee's  agents and employees.
Lessee shall  immediately give written notice to Lessor of the need for repairs,
which repairs shall be made by Lessor  beginning not more than fifteen (15) days
after written notice by Lessee.  Lessor shall not be liable to Lessee, except as
expressly  provided in the Lease,  for any damage or  inconvenience,  and Lessee
shall not be entitled to any  abatement  or  reduction  of rent by reason of any
repairs,  alterations  or  additions  made by Lessor  under this Lease except as
provided for in Paragraph 13.

         (b) Lessee  Obligations  (i) Except as  indicated  hereinabove,  Lessee
shall, at its own cost and expense, maintain all parts of the Building and other
Improvements on the Leased Premises in good repair and condition  (including all
necessary  replacements),  including,  but not limited to,  dock  bumpers,  pest
control and  extermination,  and regular  removal of debris.  Lessee shall enter
into a service contract for maintenance of the heating,  ventilating and cooling
systems  with  a  qualified   mechanical   contractor   providing  for  complete
maintenance service at six (6) month intervals.

(ii)  Lessee  shall not allow any damage to be  committed  on any portion of the
Leased  Premises,  and at the  termination  of this  Lease,  by lapse of time or
otherwise,  Lessee  shall  deliver  the  Leased  Premises  to  Lessor in as good
conditions as existed at the Commencement Date of this Lease,  ordinary wear and
tear  excepted.  The cost and  expense of any repairs  necessary  to restore the
condition  of the  Leased  Premises  shall  be borne by  Lessee,  and if  Lessor
undertakes to restore the Leased Premises it shall have a right of reimbursement
against Lessee.

8. COMPLIANCE WITH LAWS, RULES AND  REGULATIONS:  Lessee,  at Lessee's  expense,
shall comply with all laws,  ordinances,  orders  rules,  regulations  and other
requirements 










                                      -4-

of state,  federal,  municipal or other  agencies or bodies having  jurisdiction
relating to the use,  condition  and  occupancy of the Leased  Premises.  Lessee
shall not erect any exterior signs without the prior written approval of Lessor,
which shall not be unreasonably withheld.

9.  LESSOR  IMPROVEMENTS:  If  construction  to  the  Leased  Premises  is to be
performed  by  Lessor  prior to the  Lessee's  occupancy,  Lessor  will,  at its
expense,   commence  and/or  complete  the   construction  of  the  improvements
constituting the Leased Premises,  including partitions,  in accordance with the
plans and specifications  agreed to by the parties and made a part of this Lease
by reference.  The plans and specifications  shall be approved and signed by the
parties.  Any changes or modifications to the approved plans and  specifications
shall be made and  accepted by written  change order signed by Lessor and Lessee
and shall constitute an amendment to this Lease. Upon completion of the Building
and other improvements in accordance with the plans and  specifications,  Lessee
agrees to execute  and  deliver  to Lessor a letter  accepting  delivery  of the
Leased Premises.

In the event the Premises  shall not be  substantially  completed  and ready for
occupancy  on the date  above  fixed  for the  commencement  of the term of this
Lease, this Lease shall  nevertheless  continue in full force and effect, and no
liability  shall arise against Lessor out of any such delay beyond the abatement
of rent until the Premises are ready for  occupancy;  provided,  however,  there
shall be no  abatement  of rent if the space is not  substantially  completed to
permit  occupancy  because of the  failure of Lessee to submit  Lessee  Plans to
Lessor on a timely  basis and,  further,  there  shall be no  abatement  of rent
should  Lessee   unreasonably  delay  in  authorizing  Lessor  to  commence  the
installation  of Lessee's  work or should  Lessee  request any changes of Lessee
work in  progress  if, in Lessor's  opinion,  such change may be a cause for the
extension  of  the  date  of  substantial  completion.  If  Lessee  shall  enter
possession of all or any part of the Premises and commence its business from the
Premises prior to the date fixed above for the first day of the term, all of the
covenants and  conditions of this lease shall be binding upon the parties hereto
in respect of such  possession the same as if the first day of the term had been
fixed as of the date which Lessee  entered such  possession and Lessee shall pay
to  Lessor  as rent for the  period  prior to the  first day of the term of this
Lease a proportionate amount of the rent set forth in the Rent Schedule.

10. ALTERATIONS AND IMPROVEMENTS:  Lessee shall not make or allow to be made any
alterations  or physical  additions in or to the Leased  Premises  without first
obtaining  the  written  consent  of  Lessor  which  shall  not be  unreasonably
withheld.  Any  alterations,  physical  additions or  Improvements to the Leased
Premises made by Lessee shall at once become the property of Lessor and shall be
surrendered to Lessor upon the termination of this Lease. Lessor, at its option,
may  require  Lessee  to  remove  any  physical   additions  and/or  repair  any
alterations in order to restore the Leased Premises to the condition existing at
the time Lessee took possession,  all costs of removal and/or  alterations to be
borne by Lessee.  This clause shall not apply to moveable equipment or furniture
owned by Lessee  which may be  removed  by Lessee at the end of the term of this
Lease if Lessee is not then in default and if such  equipment  and  furniture is
not then subject to any other rights, liens and interest of Lessor.








                                      -5-

11.  LIENS:  Lessee  shall  not  permit  any lien or  claim  for any lien of any
mechanic,  laborer  or  supplier  or any  other  lien to be  filed  against  the
Building, the land on which the Building is located, the Leased Premises, or any
part thereof  arising out of work  performed,  or alleged to have been performed
by, or at the  direction  of, or on behalf of Lessee.  If any such lien or claim
for lien is filed,  Lessee  immediately either shall have such lien or claim for
lien  released  of record or shall  deliver to Lessor  either:  (i) a bond form,
content,  amount,  and issued by surety,  satisfactory  to Lessor,  indemnifying
Lessor  and  others  designated  by Lessor  against  all  costs and  liabilities
resulting  from  such lien or claim for lien and the  foreclosure  or  attempted
foreclosure  thereof,  or (ii)  endorsements to the title policies of Lessor and
Lessor's  mortgagee  "Insuring  Over"  such  liens  satisfactory  to Lessor  and
Lessor's mortgagee, respectively. If Lessee fails to have such lien or claim for
lien so  released  or to deliver  such a bond or title  endorsements  to Lessor,
Lessor,  without  investigating  the validity of such lien, may pay or discharge
the same and Lessee shall reimburse Lessor upon demand for the amount so paid by
Lessor,  including  Lessor's  expenses and attorney's fees. At Lessee's request,
Lessor will grant a waiver of lien rights to Lessee's inventory.

12.  CONDEMNATION:  (a) Substantial Taking If, during the term (or any extension
or renewal) of this Lease,  all or a substantial part of the Leased Premises are
taken for any public or quasipublic use under any governmental law, ordinance or
regulation,  or by right of eminent  domain or by purchase in lieu thereof,  and
such taking or purchase  would prevent or materially  interfere  with the use of
the Leased  Premises  for the purpose  for which they are then being used,  this
Lease shall terminated and the rent shall be abated during the unexpired portion
of this  Lease  effective  on the  date  physical  possession  is  taken  by the
condemning  authority.  Lessee shall have no claim to the condemnation  award or
any part thereof,  unless some portion of the award is specifically allocated to
Lessee. Lessee can pursue its own claims.

         (b) Partial Taking In the event a portion of the Leased  Premises shall
be taken  for any  public  or  quasi-public  use  under  any  governmental  law,
ordinance or  regulation,  or by right of eminent  domain or by purchase in lieu
thereof, and this Lease is not terminated as provided in subparagraph (a) above,
Lessor may, at  Lessor's  sole risk and  expense,  restore and  reconstruct  the
Building and other  Improvements on the Leased Premises to the extent  necessary
to make it reasonably  tenantable.  The rent payable under this Lease during the
unexpired portion of the term shall be adjusted to such an extent as may be fair
and  reasonable  under  the  circumstances.  Lessee  shall  have no claim to the
condemnation  award or any part  thereof,  unless  some  portion of the award is
specifically allocated to Lessee. Lessee can pursue its own claims.

13. FIRE AND CASUALTY:  (a) Substantial  Damage If the Leased Premises should be
totally destroyed by fire or other casualty, or if the Leased Premises should be
so damaged so that rebuilding  cannot reasonably be completed within one hundred
and eighty (180) working days after the date of written  notification  by Lessee
to Lessor of the  destruction,  this Lease shall  terminate,  and if such damage
shall  not have been  caused by the fault or  neglect  of  Lessee,  its  agents,
employees,  invitees, or those for whom Lessee is responsible, the rent shall be
abated for the unexpired  portion of the Lease,  effective as of the date of the
written notification.









                                      -6-

         (b) Partial Damage If the Leased Premises  should be partially  damaged
by fire or other casualty, and rebuilding or repairs can reasonably be completed
within  one  hundred  and  eighty  (180)  working  days from the date of written
notification  by  Lessee  to Lessor of the  destruction,  this  Lease  shall not
terminate, but Lessor may proceed with reasonable diligence to rebuild or repair
the Building or other improvements to substantially the same conditions in which
they existed  prior to the damage.  If the Leased  Premises are to be rebuilt or
repaired and are untenantable in whole or in part following the damage,  and the
damage or  destruction  was not caused or contributed to by act or negligence of
Lessee, its agents, employees, invitees or those for whom Lessee is responsible,
the rent  payable  under  this  Lease  during  the  period  for which the Leased
Premises are untenantable shall be adjusted to such an extent as may be fair and
reasonable under the  circumstances  and mutually agreed upon by both the Lessee
and Lessor.  In event that Lessor  fails to complete  the  necessary  repairs or
rebuilding  within one hundred and eighty  (180)  working  days from the date of
written  notification by Lessee to Lessor of the destruction,  Lessee may at its
option  terminate  this Lease by delivering  written  notice of  termination  to
Lessor,  whereupon  all rights and  obligations  under this Lease shall cease to
exist.

14. PROPERTY INSURANCE:  Lessor shall at all times during the term of this Lease
maintain a policy or policies of insurance  with the  premiums  paid in advance,
issued by and binding upon a solvent  insurance  company,  insuring the Building
against all risk of direct  physical loss in an amount equal to 100% of the full
insurable  value of the Building  structure and its  improvements  (exclusive of
excavation and foundation costs and costs of conduits, pilings and other similar
underground  items and costs of parking  lot paving and  landscaping)  as of the
date of the loss,  provided,  that Lessor  shall not be  obligated in any way or
manner to insure any  personal  property  (including,  but not  limited  to, any
furniture, machinery, goods or supplies) of Lessee or which Lessee may have upon
or within the Leased  Premises or any fixtures,  installed  machinery,  goods or
supplies of Lessee or which  Lessee may have upon or within the Leased  Premises
or any  fixtures  installed  by or paid for by Lessee  upon or within the Leased
Premises or any additional Improvements which Lessee may construct on the Leased
Premises.

15.   WAIVER  OF   SUBROGATION:   Anything   in  this  Lease  to  the   contrary
notwithstanding,  to the extent that Lessor or Lessee shall be or have the right
to be reimbursed  by insurance,  Lessor and Lessee hereby waive and release each
other of and from any and all  rights  of  recovery,  claim,  action or cause of
action, against each other, their agents,  officers and employees,  for any loss
or damage that may occur to the Leased Premises, Improvements to the Building of
which the Leased Premises are a part, or personal property  (Building  Contents)
within the  Building,  by reason of fire or the elements  regardless of cause or
origin.  Because  this  paragraph  will  preclude  the  assignment  of any claim
mentioned in it by way of  subrogation  or otherwise to an insurance  company or
any other person,  each party to this Lease agrees  immediately  to give to each
insurance company which has issued to it policies of insurance covering all risk
of direct  physical  loss,  written  notice of the terms of the  mutual  waivers
contained  in  this  paragraph,  and to have  the  insurance  policies  properly
endorsed,  if necessary,  to prevent the invalidation of the insurance coverages
by reason of the mutual waivers contained in this paragraph.










                                      -7-

16. HOLD  HARMLESS:  Lessor shall not be liable to Lessee's  employees,  agents,
invitees,  licensees  or  visitors,  or to any other  person,  for any injury to
person or damage to  property  on or about  the  Leased  premises  caused by the
negligence or misconduct of Lessee, its agents, servants or employees, or of any
other  person  entering  upon the  Leased  Premises  under  express  or  implied
authority of Lessee.  Lessee agrees to indemnify and hold harmless Lessor of and
from any loss,  attorney's  fees,  expenses  or claims  arising  out of any such
damage or injury.

17. QUIET  ENJOYMENT:  Lessor  warrants that it has full right to execute and to
perform this Lease and to grant the estate demised and that Lessee, upon payment
of the  required  rents and  performing  the terms,  conditions,  covenants  and
agreements  contained in this Lease,  shall peaceably and quietly have, hold and
enjoy the  Leased  Premises  during  the full term of this  Lease as well as any
extension or renewal  thereof.  Lessor shall not be responsible  for the acts or
omissions of any other Lessee or third party that may  interfere  with  Lessee's
use and enjoyment of the Leased Premises.

18.  LESSOR'S RIGHT OF ENTRY:  Lessor shall have the right,  upon 24 hours prior
notice,  at all reasonable hours, to enter the Leased Premises for the following
reasons: inspection;  cleaning or making repairs; showing the Leased Premises to
prospective  tenants  or  purchasers;  determining  Lessee's  use of the  Leased
Premises,  or  determining  if an act of default  under this Lease has occurred.
Lessee may escort Lessor or its agents while on Lease Premises.

19.  ASSIGNMENT AND SUBLETTING:  (a) Lessor's Rights Lessor shall have the right
to transfer and assign,  in whole or in part, its rights and  obligations in the
Building and property that are the subject of this Lease.

         (b) Lessee's  Restrictions.  (i) without the prior  written  consent of
Lessor,  which  shall not be  unreasonably  withheld,  Lessee may not  sublease,
assign,  mortgage,  pledge,  hypothecate  or  otherwise  transfer  or permit the
transfer of this lease or the  interest of Lessee in this Lease,  in whole or in
part,  by operation  of law or  otherwise.  If Lessee  desires to enter into any
sublease of the Leased Premises,  Lessee shall deliver written notice thereof to
Lessor,  together with financial and other information  sufficient for Lessor to
make an informed judgement with respect to such proposed sublease.  Any approved
sublease  shall be expressly  subject to the terms and conditions of this Lease.
In the event of any assignment or subletting, Lessee shall never the less at all
times  remain  fully  responsible  and  liable  for the  payment of the rent and
compliance with all of its other  obligations under the terms,  provisions,  and
covenants of this Lease. Upon the occurrence of an "Event of Default" as defined
below,  if all or any part of the Leased  Premises are then  assigned or sublet,
Lessor,  in addition to any other remedies provided by this Lease or provided by
law, may at its option,  collect  directly  from the  assignee or subtenant  all
rents becoming due to Lessee by reason of the assignment or sublease, and Lessor
shall have a security  interest  in all  properties  on the Leased  Premises  to
secure payment of such sums. Any collection directly by Lessor from the Assignee
or subtenant  shall not be  construed  to  constitute a novation or a release of
Lessee from the further performance of its obligations under the Lease.

                  (ii) In the event Lessee desires to enter into any sublease of
the Leased  Premises,  Lessor  shall have the option to exclude  from the Leased
Premises  covered  by the 









                                      -8-

Lease,  the space proposed to be sublet by Lessee,  effective as of the proposed
Commencement Date of sublease of said space by Lessee.  Lessor may exercise said
option  after Lessee  notifies  Lessor of the  proposed  sublease.  In the event
Lessor exercises said option,  Lessee shall surrender possession of the proposed
sublease  space to Lessor on the effective  date of exclusion of said space from
the Leased Premises  covered by this Lease,  and neither party hereto shall have
any further rights or liabilities with respect to said space under this Lease.

20. DEFAULT BY LESSEE:  The following shall be deemed to be Events of Default by
Lessee under this Lease:

         (a) Delinquent  Rent Lessee shall fail to pay when due any  installment
of rent or any other payment required pursuant to this Lease and such failure to
pay continues for five days from date of notice;

         (b) Abandonment  Lessee shall abandon any substantial portion of the
Leased Premises;

         (c) Other Defaults Lessee shall fail to comply with any term, provision
or covenant of this  Lease,  other than the payment or rent,  and the failure is
not cured within ten (10) days after written notice to Lessee;

         (d) Bankruptcy  Lessee shall file a petition or be adjudged bankrupt or
insolvent under the National  Bankruptcy Act, as amended,  or any similar law or
statute of the United  States or any state;  or a receiver  or trustee  shall be
appointed for all or substantially  all of the assets of Lessee; or Lessee shall
make a transfer in fraud of creditors or shall make an assignment for benefit of
creditors; or

         (e) Liens Lessee shall do or permit to be done any act which results in
a lien being filed against the Leased Premises or the Building and/or Project of
which the Leased Premises are a part.

21. REMEDIES FOR LESSEE'S  DEFAULT:  Upon the occurrence of any event of default
set forth in this Lease,  Lessor shall have the option to pursue any one or more
of the following remedies without any notice or demand:

         (a)  Termination.  Terminate  this Lease,  in which event  Lessee shall
immediately  surrender the Leased Premises to Lessor, and if the Lessee fails to
surrender the Leased Premises, Lessor may, without prejudice to any other remedy
which it may have for  possession  or  arrearages  in rent,  enter upon and take
possession of the Leased Premises, by picking or changing locks if necessary and
lock out,  expel, or remove Lessee and any other person who may be occupying all
or any part of the Leased  Premises  without being liable for prosecution of any
claim for  damages.  Lessee  agrees to pay on demand  the amount of all loss and
damage which Lessor may suffer by reason of the  termination  of the Lease under
this  subparagraph,  whether  through  inability to relet the Leased Premises on
satisfactory terms or otherwise.








                                      -9-

         (b) Entry and  Reletting  Enter upon and take  possession of the Leased
Premises by picking or changing lock if necessary, and lock out, expel or remove
Lessee and any other person who may be  occupying  all or any part of the Leased
Premises  without  being  liable for any claim or damages,  and relet the Leased
Premises  on behalf of Lessee  and  receive  directly  the rent by reason of the
reletting.

         (c) Entry and Performing  Lessee's  Obligations.  Enter upon the Leased
Premises,  by picking or changing  locks if necessary,  without being liable for
prosecution or any claim for damages,  and do whatever Lessee is obligated to do
under the terms of this Lease.  Lessee agrees to reimburse  Lessor on demand for
any  expenses  which  Lessor may incur in  effecting  compliance  with  Lessee's
obligations  under this Lease;  further,  Lessee agrees that Lessor shall not be
liable for any  damages  resulting  to Lessee  from  effecting  compliance  with
Lessee's  obligations under this subparagraph  caused by negligence of Lessor or
otherwise.

22.  WAIVER OF  DEFAULT  OR  REMEDY:  Failure  of Lessor to  declare an event of
default  immediately  upon its  occurrence,  or delay in  taking  any  action in
connection  with an event of  default,  shall  not  constitute  a waiver  of the
default,  but Lessor shall have the right to declare the default at any time and
take such action as is lawful or authorized under this Lease. Pursuit of any one
or more of the  remedies  set forth in  Paragraph  21 above  shall not  preclude
pursuit  of any one or more of the other  remedies  provided  elsewhere  in this
Lease or provided by law, nor shall  pursuit of any remedy  provided  constitute
forfeiture or waiver of any rent or damages  accruing to Lessor by reason of the
violation of any of the terms, provisions or covenants of this Lease. Failure by
Lessor to enforce one or more of the remedies  provided upon an event of default
shall not be deemed or construed to constitute a waiver of the default or of any
other violation or breach of any of the terms, provisions or covenants contained
in this Lease.

23.  ACTS OF GOD:  Lessor  shall not be  required  to perform  any  covenant  or
obligation  in this  Lease,  or be liable in damages  to Lessee,  so long as the
performance or non-performance of the covenant or obligation is delayed,  caused
by or prevented by an Act of God or Force Majeure.

24.  ATTORNEY'S  FEES:  Lessee  shall pay upon demand,  all costs and  expenses,
including  reasonable  attorney's  fees,  incurred  by Lessor in  enforcing  the
observance and performance by Lessee of all covenants,  conditions provisions of
this Lease or resulting from Lessee's  default under this Lease. In the event of
default by Lessor,  Lessee  shall be entitled  to  attorney's  fees  required to
enforce any remedies resulting from such default.

25.  SURRENDER OF PREMISES:  Upon  expiration  or  termination  of this Lease or
termination of Lessee's right of possession of the Leased Premises. Lessee shall
vacate the Leased premises.  Lessee shall immediately deliver possession thereof
to Lessor in a clean,  good and  tenantable  condition,  ordinary  wear and tear
accepted.  Upon any  termination  which  occurs other than by reason of Lessee's
default, Lessee shall be entitled to remove from the Leased Premises all movable
personal  property of Lessee's  provided  Lessee  immediately  shall  repair all
damage  resulting  from such  removal and shall  restore the Leased  Premises to
tenantable  condition.  In the event  possession  of the Leased  Premises is not
immediately  delivered  to  Lessor  or if Lessee  shall  fail to  remove  all of
Lessee's movable  property as aforesaid,  Lessor may









                                      -10-

remove any of such property  therefrom without any liability of Lessor to Lessee
or any other party.  All movable  property  which may be removed from the Leased
Premises by Lessor  shall be  conclusively  presumed to have been  abandoned  by
Lessee  and  title  thereto  shall  pass to  Lessor  without  any cost or credit
therefore  and Lessor may at its option and at Lessee's  expense,  store  and/or
dispose of such property.

26. HOLDING OVER: In the event of holding over by Lessee after the expiration or
termination of this Lease, the hold over shall be as a tenant at will and all of
the terms and  provisions of this Lease shall be applicable  during that period.
Lessee  shall pay  Lessor as rental  for the  period of such hold over an amount
equal to one and  one-half  (1-1/2) of the rent which would have been payable by
Lessee had the hold over period been a part of the original  term of this Lease.
Lessee agrees to vacate and deliver the Leased  Premises to Lessor upon Lessee's
receipt of notice from Lessor to vacate. The rental payable during the hold over
period shall be payable to Lessor on demand. No holding over by Lessee,  whether
with or without consent of Lessor,  shall operate to extend this Lease except as
otherwise expressly provided.

27. RIGHTS OF FIRST AND SECOND MORTGAGEE:  Lessee accepts this Lease subject and
subordinate  to any  recorded  first and second  mortgage  or deed of trust lien
presently  existing or  hereafter  created upon the Leased  Premises.  Lessor is
hereby irrevocably vested with full power and authority to subordinate  Lessee's
interest under this Lease to any first and second mortgage or deed of trust lien
hereafter  placed on the Leased  Premises,  and  Lessee  agrees  upon  demand to
execute additional  instruments  subordinating this Lease as Lessor may require.
If the  interests of Lessor under this Lease shall be  transferred  by reason of
foreclosure or other proceedings for enforcement of any first or second mortgage
or deed of trust on the Leased Premises, Lessee shall be bound to the transferee
(sometimes  called the `Purchaser'),  at the option of the Purchaser,  under the
terms,  covenants  and  conditions  of this  Lease for the  balance  of the term
remaining,  and any  extensions or renewals with the same force and effect as if
the Purchaser were Lessor under this Lease,  and, if requested by the Purchaser,
Lessee  agrees  to  atone to the  Purchaser,  including  the  first  and  second
mortgagee  under any such mortgage if it be the  Purchaser,  as its Lessor.  The
transfer of any interest of Lessor under this Lease shall not diminish  Lessee's
rights under the Lease as long as it is not in default hereunder.

28. ESTOPPEL CERTIFICATES:  Lessee agrees to furnish promptly from time to time,
upon  request  of Lessor or  Lessor's  mortgagee,  a  statement  certifying,  if
applicable,  that Lessee is in  possession  of the Leased  premises;  the Leased
Premises  are  acceptable;  the Lease is in full force and effect;  the Lease is
unmodified;  Lessee claims no present  charge,  liens or claim of offset against
rent; the rent is paid for the current  month,  but is not prepaid for more than
one month and will not be prepaid for more than one month in  advance;  there is
no existing default by reason of some act or omission by Lessor;  and such other
matters as may be reasonably required by Lessor or Lessor's mortgagee.

29.  SUCCESSORS:  Subject to  Paragraphs  20 and 21 hereof,  this Lease shall be
binding  upon and insure to  benefit  of Lessor and Lessee and their  respective
heirs,  personal  representatives,  successors  and  assigns,  and  if  Lessor's
interest in the Leased Premises cease to exist for any reason during the term of
this lease,  then,  notwithstanding  the  happening  of such 








                                      -11-

event,  this Lease  nevertheless  shall remain  unimpaired and in full force and
effect  and  Lessee  hereunder  agrees to atone to the then  owner of the Leased
Premises.

30. RENT TAX: If applicable in the  jurisdiction  where the Leased  Premises are
situated,  Lessee shall pay and be liable for all rental, sales and use taxes or
other similar taxes,  related to the leased  Premises,  levied or imposed by any
city,  state,  or county  or other  governmental  body  having  authority,  such
payments to be in addition to all other  payments  required to be paid to Lessor
by  Lessee  under  the  terms  of this  Lease.  Any such  payment  shall be paid
concurrently  with the  payment  of the rent upon  which the tax is based as set
forth above.

request by the  addressee  thereof.  Rejection or other refusal to accept or the
inability  to deliver  because  of changed  address of which no notice was given
shall be deemed to be receipt of the notice, demand or request sent.

harmless  from any  claim or  claims,  as well as costs and  expenses  including

option  apply such part of the deposit as may be  necessary to cure the default,
and if Lessor does so, Lessee shall upon demand make such additional  deposit as
may be required to maintain the sum of $10,000.00 on hand.  Upon the termination
of this Lease, Lessor shall,  provided the Lessee is not in any default,  refund
to Lessee the balance held by Lessor without interest. In the event of a sale of
the Land and Building of which the Leased premises are a part, Lessor shall have

solely for the return of said deposit.

                  3) All  obligations  of  Lessee  shall  be  guaranteed  by all
Shareholders  of Lessee  pursuant  to a Lease  Guaranty  Agreement  of even date
herewith.

LESSEE,  AS A MATERIAL  CONSIDERATION FOR THE EXECUTION OF THIS LEASE, THAT THIS
LEASE,  WITH THE SPECIFIC  REFERENCES  TO WRITTEN  EXTRINSIC  DOCUMENTS,  IS THE

REPRESENTATIONS,   WARRANTIES,   UNDERSTANDINGS,   STIPULATIONS,  AGREEMENTS  OR
PROMISES  PERTAINING TO THIS LEASE OR THE EXPRESSLY  MENTIONED WRITTEN EXTRINSIC
DOCUMENTS NOT INCORPORATED IN WRITING IN THIS LEASE. LESSOR AND LESSEE EXPRESSLY
AGREE THAT  THERE ARE AND SHALL BE NO IMPLIED  WARRANTIES  WHICH  EXTEND  BEYOND

June , 1997, by and among DynaGen, Inc.  ("DynaGen"),  DynaGen Acquisition Corp.

approximately  37,323 square foot  office/warehouse  building situated on a 6.93
+/- acre parcel  located at 1385 Kemper  Meadow  Drive,  Forest Park,  Ohio (the

         WHEREAS,  in  anticipation of the Merger and in order to induce DynaGen

                                    AGREEMENT

         NOW,  THEREFORE,  in  consideration of the foregoing and the respective

         the  contrary,  Lessor  hereby agrees that the consent of Lessor is not
         required  with  respect to the  completion  of the  Merger,  and Lessor
         hereby  waives  any  right to  claim  that the  Merger  constitutes  an

         2.  Amendment.  Lessor and Lessee  hereby agree that the Lease shall be
         amended as follows:

                  (a) The  following  paragraph is added to the end of Section 1
                  of the Lease as a further definition of the Leased Premises:

                           Lessee shall have the  appurtenant  rights to use (i)
                           all  parking  areas  on said  Lot  No.  3,  (ii)  all
                           driveways, entrances and walkways providing access to

                           Lessor's  interest  therein,   (iii)  all  easements,
                           rights-of-way  and  other   appurtenant   rights  and
                           interests  benefiting  said Lot 3 from  time to time,
                           and (iv) all wires, cables, pipes,  conduits,  mains,
                           equipment  and other  improvements  necessary  for or
                           relating  to  the  provision  of   electrical,   gas,
                           telephone,  cable,  drainage,  water, sewer and other
                           utility  services to the  Building,  to the extent of
                           Lessor's  interest  therein.  The  Building  and such

                           called the "Leased Premises".

                  (b) The "Base Rental Schedule" (attached to the Lease),  which
                  is incorporated into Section 3 of the Lease, is hereby amended
                  to delete  the  phrase  "Months  2-120"  and insert the phrase

                           shall  pay  when  due  all  Real  Estate   Taxes  (as

                           and shall not allow any  penalties  or interest to be
                           assessed  due to the  failure to pay such Real Estate
                           Taxes.

                  (d)  Section  7(a) is  hereby  amended  to add  the  following

                           repair of any damage caused by fire or other casualty
                           or for any  damage  for which  Lessor  has waived its
                           rights against  Lessee  pursuant to Section 15 of the
                           Lease.

                  (e) Section 7(b)(ii) is hereby amended such that the following
                  language  is added at the end of the  first  sentence  thereof

                           personal property (including, without limitation, the
                           storage and  material  handling  equipment)  from the
                           Leased  Premises  during or at the  expiration of the
                           term without the consent or approval of Lessor or any
                           other party and any damage  caused  thereby  shall be
                           repaired by Lessee; provided, however that during the
                           term of the Lease and for as long as the  interest of
                           the First  Mortgagee  (as  defined  below) is in full
                           force  and  effect,  Lessee  shall  obtain  the prior
                           consent of the First Mortgagee of such removal (which

                                    (t)     Section 19(b)(ii) is hereby deleted.

                           other than The  Huntington  National Bank (the "First
                           Mortgagee")  and  Hamilton  County  Development  Co.,

                           Lessor  shall use its best efforts to obtain from the
                           Existing   Mortgagees   and   deliver  to  Lessee  an
                           agreement  for Lessee's  benefit (a  "Non-Disturbance
                           Agreement")   providing   that,  if  either  Existing
                           Mortgagee (or any of its  successors in interest with
                           respect  to  the  Leased   Premises  or  this  Lease)
                           acquires title to the Leased  Premises or succeeds to

                           a  "Foreclosure"),  such  Existing  Mortgagee (or its
                           successors) shall not disturb Lessee's  possession of
                           the Leased Premises under this Lease, shall recognize
                           Lessee's  rights as tenant under this Lease and shall
                           assume  Lessor's  obligations  under  this Lease that
                           arise or accrue  after such  Foreclosure,  so long as
                           Lessee is not in  default  of its  obligations  under
                           this Lease after any applicable notice and beyond any
                           applicable  cure  periods  under this  Lease.  Lessor
                           shall obtain and deliver to Lessee a  Non-Disturbance
                           Agreement   from   the   holders   of  any   Security
                           Instruments  under  which any party now or

                           being   a   "New    Security    Instrument").    Each
                           Non-Disturbance  Agreement  shall  require such other
                           holders to give Lessee  written notice of any default
                           by  Lessor  in  the  payment  or  performance  of its
                           obligations  secured by the Security  Instrument that
                           is the  subject  of such  Non-Disturbance  Agreement.
                           Notwithstanding any contrary provision of this Lease,

                           Security Instrument,  (ii) the power and authority of
                           Lessor to subordinate  this Lease to any New Security
                           Instruments,   (iii)  the  obligation  of  Lessee  to
                           subordinate   this   Lease   to  any   New   Security
                           Instruments,  (v) the option of any Purchaser to bind
                           Lessee under this Lease after the  Foreclosure  under
                           any New Security  Instrument,  and (v) the obligation
                           of Lessee to attorn to any such  Purchaser  shall all
                           be    conditioned    upon    Lessee    receiving    a
                           Non-Disturbance  Agreement  with  respect to such New

                  been amended prior to the date hereof;

                  (b) The Lease is in full  force and  effect  according  to the
                  terms set forth in Exhibit A;



                                      -4-







                  (c) Lessor is the holder of the  lessor's  interest  under the
                  Lease and holds fee title to the Leased Premises;

                  (d)  Lessor  has not  delivered  to Lessee a notice of default
                  under the Lease;

                  (e)  Neither  Lessee nor  Lessor is not in  default  under the
                  Lease,  nor has any event occurred which,  after the giving of
                  any  applicable  notice,  and/or such  expiration  date of any
                  applicable  grace period  which would  constitute a default by

         5. Payment of Rent/Release of Guaranty.  Notwithstanding  any provision
of the  Lease  to the  contrary,  for so long as  Lessee  or its  affiliates  or
successors  shall have any obligations with respect to any debt of Lessor now or
hereafter  secured by an interest  in the Leased  Premises or this Lease under a
Security Instrument (a "Secured  Obligation"),  Lessee shall have the right, but
not the  obligation,  at any time and from time to time,  to pay the Base Rental
and any other rent due under the Lease directly to the creditor or holder of any

the obligations,  monetary or otherwise, owed or due to the Existing Mortgagees.
Before  March 31, 2000,  Lessor  shall cause Lessee to be released  from (i) all
guaranties in effect as of the date of this Lease with respect to any present or
future  liabilities,  debts and other obligations of Lessor,  and (ii) all other
Secured Obligations.

                           COMMERCIAL LEASE AGREEMENT

THIS LEASE  AGREEMENT  is made and  entered  into as of the date set forth below
between SPC PROPERTIES  LIMITED,  and Ohio limited liability company,  hereafter
referred to as "Lessor" and SUPERIOR PHARMACEUTICAL COMPANY, an Ohio corporation
hereinafter referred to as "Lessee":

                                   WITNESSETH

1.  LEASE  PREMISES:  In  consideration  of the  rents,  terms,  provisions  and
covenants of this Lease,  Lessor hereby leases,  lets, and demises to Lessee the
following described premises:

         Approximately 37,323 square feet  office/warehouse  building (Building)
         comprising 100% of Lessor's building (Lessee's  Percentage) situated on
         a 6.93 +/- acre parcel located at 1385 Kemper Meadow Drive, in the City
         of Forest Park,  Hamilton County,  Ohio, and being further described as
         follows:

         Lot No. 3 of Kemper Meadow Business Center, Block "B", recorded in Plat
         Book 312, Page 36, of the Hamilton County, Ohio Plat Records, and being
         subject to all legal highways, easements and restrictions of record.

2. INITIAL TERM: Subject to and upon the conditions set forth below, the term of
this  Lease  shall   commence  upon  issuance  of  a  certificate  of  occupancy
("Commencement  Date").  The Lease shall  terminate on the last day of the 241st
month thereafter.

3. RENT:  (a) BASE RENT:  Lessee agrees to pay monthly as Base Rental during the
term of this Lease the sums as indicated on the  attached  "Base Rent  Schedule"
(Exhibit B), which amounts shall be payable to Lessor at the address shown below
on the first day of the month. One monthly  installment of rent shall be due and
payable on the day of  execution  of this Lease by Lessee for the first  month's
rent and a like  monthly  installment  shall be due and payable on or before the
first day of each calendar month, as indicated on the Rent Schedule,  during the
demised term;  provided,  that if the "Commencement Date" should be a date other
than the first day of a calendar month, the monthly rental set forth above shall
be pro-rated to the end of that calendar month, and all succeeding  installments
of rent shall be payable on or before the first day of each succeeding  calendar
month during the demised term. Lessee shall pay, as additional rental, all other
sums due under this Lease.

         (b) INSURANCE  PREMIUMS:  Lessor shall provide and Lessor shall pay for
the All Risk Fire and Extended Coverage  Insurance for the Building with loss of
rent endorsement. However, at Lessee's option and subject to Lessor's review and
approval as to form,  content  and  carrier,  Lessee may  provide  the  Building
insurance  to  Lessor  at  Lessee's  expense.  The  costs  associated  with said
insurance  coverage  shall be  included  in the Base  Rent as  indicated  on the
attached "Base Rent Schedule" (Exhibit B). If, however,  the lessee pays for the
cost of the  insurance  then the lessee shall  receive a credit on the Base Rent
for the actual amount paid.












         (c) REAL ESTATE TAX: The total rental to be paid under this Lease shall
also  include  all real  estate  taxes  and  assessments  levied  on the  Leased
Premises.  Such  payments  be  included  in the Base  Rent as  indicated  on the
attached "Base Rent Schedule' (Exhibit B).

         (d)  SERVICE   CHARGE:   Other   remedies   for   nonpayment   of  rent
notwithstanding,  if the monthly  rental payment is not received by Lessor or if
any other  payment  due Lessor by Lessee is not  received by Lessor on or before
the fifth (5th) day after it is due, a service  charge of five  percent  (5%) of
such past due amount  shall  become due and payable in addition to such  amounts
owed under this Lease.

It is the Lessee's  responsibility to pay on a timely basis all costs associated
with the use and  occupancy of the Leased  Premises  including , but not limited
to,  all taxes,  other  than Real  Estate  Taxes and  assessments,  maintenance,
repairs, grounds keeping and snow removal.

4. USAGE:  Lessee  warrants and  represents  to Lessor that the Leased  Premises
shall  be  used  and  occupied   only  for  the  purposes  of  the  "Lessee"  as
office/warehouse  space.  Lessee shall occupy the Leased  Premises,  conduct its
business and control its agents, employees,  invitees and visitors in such a way
as is lawful,  reputable and will not create any nuisance or otherwise interfere
with,  annoy or disturb any property owner in Kemper Meadow  Business  Center in
its normal  business  operations  or Lessor in its  management  of the Premises.
Lessee  shall not  commit,  or suffer to be  committed,  any waste on the Leased
Premises.

5. INSURANCE: Use of Premises. Lessee shall not permit the Leased Premises to be
used in any way which could be extra  hazardous  on account of fire or otherwise
which  would in any way  increase  or  render  void the  fire  insurance  on the
Building or any part  thereof or any  contents in the  Building  belonging to or
used by Lessor.  If at any time during the term of this Lease the State Board of
Insurance  or other  insurance  authority  disallows  any of Lessor's  sprinkler
credits or imposes an  additional  penalty or  surcharge  in Lessor's  insurance
premiums because of Lessee's original or subsequent  placement or use of storage
racks or bins,  method of storage or nature of Lessee's  inventory  or any other
act of  Lessee,  Lessee  agrees to pay as  additional  rental  the  increase  in
Lessor's insurance premiums.

         Lessee shall carry, at its expense, liability insurance on the Premises
throughout  the Lease Term covering both Lessee and Lessor as named insureds and
if Lessor elects, any owner and/or Lessee of the land upon which the building is
located, as additional named insured,  with terms and companies  satisfactory to
Lessor  and  having a combined  single  limit,  providing  both  bodily  injury,
including death resulting therefrom, and property damage coverage, to the extent
of $2,000,000.00, arising out of the Ownership, maintenance or use of the Leased
Premises. Lessee shall also carry insurance against fire and such other risks as
are from time to time included in standard extended coverage insurance, insuring
the full  replacement  cost of all  leasehold  improvements  paid for by Lessee,
including  wall  coverings,  carpeting,  furnishings  and  equipment.  All  such
policies  shall be cancelable  only upon ten (10) days prior  written  notice to
Lessee and Lessor.  Prior to the Commencement  Date and within fifteen (15) days
prior to the  expiration of each such policy,  Lessee shall furnish  Lessor with
copies of such policies or  certificates  evidencing  that such  insurance is in
full force and effect and stating the terms thereof.

6. UTILITY SERVICE:  Lessor shall provide the normal utility service  connection
into the Leased  Premises as indicated on approved  construction  plans.  Lessee
shall pay the cost of all utility services,  including,  but not limited to, all
charges for gas, water and electricity used on the Leased Premises. Lessee shall
pay all costs caused by Lessee introducing  excessive pollutants or solids other
than human waste into the sanitary  sewer system,  including  permits,  fees and
charges  levied  by any  governmental  subdivision  for any such  pollutants  or
solids.  Lessee shall be responsible for the











installation  and  maintenance  of any dilution  tanks,  settling  tanks,  sewer
sampling devices, sand traps, grease traps or similar devices as may be required
by any  governmental  subdivision for Lessee's use of the sanitary sewer system.
Lessor shall not be required to pay for any utility services, supplies or upkeep
in connection with the Leased Premises.

7. REPAIRS AND MAINTENANCE:  (a) Lessor's Obligations Unless otherwise expressly
provided, Lessor shall not be required to make any improvements, replacements or
repairs of any kind or character to the Leased  Premises during the term of this
Lease  except such repairs as are set forth in this  subparagraph.  Lessor shall
maintain only the foundation and the structural  soundness of the roof, slab and
exterior walls (excluding all windows,  window glass, plate glass and all doors)
of the  Building in good repair and  condition  except for  reasonable  wear and
tear.  Lessor  will  pass  through  any  manufacturing  warranties  on  building
components  for benefit of Lessee.  Lessee  shall  repair and pay for any damage
caused by the negligence or default of Lessee or Lessee's  agents and employees.
Lessee shall  immediately give written notice to Lessor of the need for repairs,
which repairs shall be made by Lessor  beginning not more than fifteen (15) days
after written notice by Lessee.  Lessor shall not be liable to Lessee, except as
expressly  provided in the Lease,  for any damage or  inconvenience,  and Lessee
shall not be entitled to any  abatement  or  reduction  of rent by reason of any
repairs,  alterations  or  additions  made by Lessor  under this Lease except as
provided for in Paragraph 13.

         (b) Lessee  Obligations  (i) Except as  indicated  hereinabove,  Lessee
shall, at its own cost and expense, maintain all parts of the Building and other
Improvements on the Leased Premises in good repair and condition  (including all
necessary  replacements),  including,  but not limited to,  dock  bumpers,  pest
control and  extermination,  and regular  removal of debris.  Lessee shall enter
into a service contract for maintenance of the heating,  ventilating and cooling
systems  with  a  qualified   mechanical   contractor   providing  for  complete
maintenance service at six (6) month intervals.

(ii)  Lessee  shall not allow any damage to be  committed  on any portion of the
Leased  Premises,  and at the  termination  of this  Lease,  by lapse of time or
otherwise,  Lessee  shall  deliver  the  Leased  Premises  to  Lessor in as good
conditions as existed at the Commencement Date of this Lease,  ordinary wear and
tear  excepted.  The cost and  expense of any repairs  necessary  to restore the
condition  of the  Leased  Premises  shall  be borne by  Lessee,  and if  Lessor
undertakes to restore the Leased Premises it shall have a right of reimbursement
against Lessee.

8. COMPLIANCE WITH LAWS, RULES AND  REGULATIONS:  Lessee,  at Lessee's  expense,
shall comply with all laws,  ordinances,  orders  rules,  regulations  and other
requirements  of state,  federal,  municipal or other  agencies or bodies having
jurisdiction  relating  to the  use,  condition  and  occupancy  of  the  Leased
Premises.  Lessee shall not erect any exterior  signs  without the prior written
approval of Lessor, which shall not be unreasonably withheld.

9.  LESSOR  IMPROVEMENTS:  If  construction  to  the  Leased  Premises  is to be
performed  by  Lessor  prior to the  Lessee's  occupancy,  Lessor  will,  at its
expense,   commence  and/or  complete  the   construction  of  the  improvements
constituting the Leased Premises,  including partitions,  in accordance with the
plans and specifications  agreed to by the parties and made a part of this Lease
by reference.  The plans and specifications  shall be approved and signed by the
parties.  Any changes or modifications to the approved plans and  specifications
shall be made and  accepted by written  change order signed by Lessor and Lessee
and shall constitute an amendment to this Lease. Upon completion of the Building
and other improvements in accordance with the plans and  specifications,  Lessee
agrees to execute  and  deliver  to Lessor a letter  accepting  delivery  of the
Leased Premises.










In the event the Premises  shall not be  substantially  completed  and ready for
occupancy  on the date  above  fixed  for the  commencement  of the term of this
Lease, this Lease shall  nevertheless  continue in full force and effect, and no
liability  shall arise against Lessor out of any such delay beyond the abatement
of rent until the Premises are ready for  occupancy;  provided,  however,  there
shall be no  abatement  of rent if the space is not  substantially  completed to
permit  occupancy  because of the  failure of Lessee to submit  Lessee  Plans to
Lessor on a timely  basis and,  further,  there  shall be no  abatement  of rent
should  Lessee   unreasonably  delay  in  authorizing  Lessor  to  commence  the
installation  of Lessee's  work or should  Lessee  request any changes of Lessee
work in  progress  if, in Lessor's  opinion,  such change may be a cause for the
extension  of  the  date  of  substantial  completion.  If  Lessee  shall  enter
possession of all or any part of the Premises and commence its business from the
Premises prior to the date fixed above for the first day of the term, all of the
covenants and  conditions of this lease shall be binding upon the parties hereto
in respect of such  possession the same as if the first day of the term had been
fixed as of the date which Lessee  entered such  possession and Lessee shall pay
to  Lessor  as rent for the  period  prior to the  first day of the term of this
Lease a proportionate amount of the rent set forth in the Rent Schedule.

10. ALTERATIONS AND IMPROVEMENTS:  Lessee shall not make or allow to be made any
alterations  or physical  additions in or to the Leased  Premises  without first
obtaining  the  written  consent  of  Lessor  which  shall  not be  unreasonably
withheld.  Any  alterations,  physical  additions or  Improvements to the Leased
Premises made by Lessee shall at once become the property of Lessor and shall be
surrendered to Lessor upon the termination of this Lease. Lessor, at its option,
may  require  Lessee  to  remove  any  physical   additions  and/or  repair  any
alterations in order to restore the Leased Premises to the condition existing at
the time Lessee took possession,  all costs of removal and/or  alterations to be
borne by Lessee.  This clause shall not apply to moveable equipment or furniture
owned by Lessee  which may be  removed  by Lessee at the end of the term of this
Lease if Lessee is not then in default and if such  equipment  and  furniture is
not then subject to any other rights, liens and interest of Lessor.

11.  LIENS:  Lessee  shall  not  permit  any lien or  claim  for any lien of any
mechanic,  laborer  or  supplier  or any  other  lien to be  filed  against  the
Building, the land on which the Building is located, the Leased Premises, or any
part thereof  arising out of work  performed,  or alleged to have been performed
by, or at the  direction  of, or on behalf of Lessee.  If any such lien or claim
for lien is filed,  Lessee  immediately either shall have such lien or claim for
lien  released  of record or shall  deliver to Lessor  either:  (i) a bond form,
content,  amount,  and issued by surety,  satisfactory  to Lessor,  indemnifying
Lessor  and  others  designated  by Lessor  against  all  costs and  liabilities
resulting  from  such lien or claim for lien and the  foreclosure  or  attempted
foreclosure  thereof,  or (ii)  endorsements to the title policies of Lessor and
Lessor's  mortgagee  "Insuring  Over"  such  liens  satisfactory  to Lessor  and
Lessor's mortgagee, respectively. If Lessee fails to have such lien or claim for
lien so  released  or to deliver  such a bond or title  endorsements  to Lessor,
Lessor,  without  investigating  the validity of such lien, may pay or discharge
the same and Lessee shall reimburse Lessor upon demand for the amount so paid by
Lessor,  including  Lessor's  expenses and attorney's fees. At Lessee's request,
Lessor will grant a waiver of lien rights to Lessee's inventory.

12.  CONDEMNATION:  (a) Substantial Taking If, during the term (or any extension
or renewal) of this Lease,  all or a substantial part of the Leased Premises are
taken for any public or quasipublic use under any governmental law, ordinance or
regulation,  or by right of eminent  domain or by purchase in lieu thereof,  and
such taking or purchase  would prevent or materially  interfere  with the use of
the Leased  Premises  for the purpose  for which they are then being used,  this
Lease shall terminated and the rent shall be abated during the unexpired portion
of this  Lease  effective  on the  date  physical  possession  is  taken  by the
condemning  authority.  Lessee shall have no claim to the condemnation  award or
any part 










thereof,  unless some portion of the award is specifically  allocated to Lessee.
Lessee can pursue its own claims.

         (b) Partial Taking In the event a portion of the Leased  Premises shall
be taken  for any  public  or  quasi-public  use  under  any  governmental  law,
ordinance or  regulation,  or by right of eminent  domain or by purchase in lieu
thereof, and this Lease is not terminated as provided in subparagraph (a) above,
Lessor may, at  Lessor's  sole risk and  expense,  restore and  reconstruct  the
Building and other  Improvements on the Leased Premises to the extent  necessary
to make it reasonably  tenantable.  The rent payable under this Lease during the
unexpired portion of the term shall be adjusted to such an extent as may be fair
and  reasonable  under  the  circumstances.  Lessee  shall  have no claim to the
condemnation  award or any part  thereof,  unless  some  portion of the award is
specifically allocated to Lessee. Lessee can pursue its own claims.

13. FIRE AND CASUALTY:  (a) Substantial  Damage If the Leased Premises should be
totally destroyed by fire or other casualty, or if the Leased Premises should be
so damaged so that rebuilding  cannot reasonably be completed within one hundred
and eighty (180) working days after the date of written  notification  by Lessee
to Lessor of the  destruction,  this Lease shall  terminate,  and if such damage
shall  not have been  caused by the fault or  neglect  of  Lessee,  its  agents,
employees,  invitees, or those for whom Lessee is responsible, the rent shall be
abated for the unexpired  portion of the Lease,  effective as of the date of the
written notification.

         (b) Partial Damage If the Leased Premises  should be partially  damaged
by fire or other casualty, and rebuilding or repairs can reasonably be completed
within  one  hundred  and  eighty  (180)  working  days from the date of written
notification  by  Lessee  to Lessor of the  destruction,  this  Lease  shall not
terminate, but Lessor may proceed with reasonable diligence to rebuild or repair
the Building or other improvements to substantially the same conditions in which
they existed  prior to the damage.  If the Leased  Premises are to be rebuilt or
repaired and are untenantable in whole or in part following the damage,  and the
damage or  destruction  was not caused or contributed to by act or negligence of
Lessee, its agents, employees, invitees or those for whom Lessee is responsible,
the rent  payable  under  this  Lease  during  the  period  for which the Leased
Premises are untenantable shall be adjusted to such an extent as may be fair and
reasonable under the  circumstances  and mutually agreed upon by both the Lessee
and Lessor.  In event that Lessor  fails to complete  the  necessary  repairs or
rebuilding  within one hundred and eighty  (180)  working  days from the date of
written  notification by Lessee to Lessor of the destruction,  Lessee may at its
option  terminate  this Lease by delivering  written  notice of  termination  to
Lessor,  whereupon  all rights and  obligations  under this Lease shall cease to
exist.

14. PROPERTY INSURANCE:  Lessor shall at all times during the term of this Lease
maintain a policy or policies of insurance  with the  premiums  paid in advance,
issued by and binding upon a solvent  insurance  company,  insuring the Building
against all risk of direct  physical loss in an amount equal to 100% of the full
insurable  value of the Building  structure and its  improvements  (exclusive of
excavation and foundation costs and costs of conduits, pilings and other similar
underground  items and costs of parking  lot paving and  landscaping)  as of the
date of the loss,  provided,  that Lessor  shall not be  obligated in any way or
manner to insure any  personal  property  (including,  but not  limited  to, any
furniture, machinery, goods or supplies) of Lessee or which Lessee may have upon
or within the Leased  Premises or any fixtures,  installed  machinery,  goods or
supplies of Lessee or which  Lessee may have upon or within the Leased  Premises
or any  fixtures  installed  by or paid for by Lessee  upon or within the Leased
Premises or any additional Improvements which Lessee may construct on the Leased
Premises.










15.   WAIVER  OF   SUBROGATION:   Anything   in  this  Lease  to  the   contrary
notwithstanding,  to the extent that Lessor or Lessee shall be or have the right
to be reimbursed  by insurance,  Lessor and Lessee hereby waive and release each
other of and from any and all  rights  of  recovery,  claim,  action or cause of
action, against each other, their agents,  officers and employees,  for any loss
or damage that may occur to the Leased Premises, Improvements to the Building of
which the Leased Premises are a part, or personal property  (Building  Contents)
within the  Building,  by reason of fire or the elements  regardless of cause or
origin.  Because  this  paragraph  will  preclude  the  assignment  of any claim
mentioned in it by way of  subrogation  or otherwise to an insurance  company or
any other person,  each party to this Lease agrees  immediately  to give to each
insurance company which has issued to it policies of insurance covering all risk
of direct  physical  loss,  written  notice of the terms of the  mutual  waivers
contained  in  this  paragraph,  and to have  the  insurance  policies  properly
endorsed,  if necessary,  to prevent the invalidation of the insurance coverages
by reason of the mutual waivers contained in this paragraph.

16. HOLD  HARMLESS:  Lessor shall not be liable to Lessee's  employees,  agents,
invitees,  licensees  or  visitors,  or to any other  person,  for any injury to
person or damage to  property  on or about  the  Leased  premises  caused by the
negligence or misconduct of Lessee, its agents, servants or employees, or of any
other  person  entering  upon the  Leased  Premises  under  express  or  implied
authority of Lessee.  Lessee agrees to indemnify and hold harmless Lessor of and
from any loss,  attorney's  fees,  expenses  or claims  arising  out of any such
damage or injury.

17. QUIET  ENJOYMENT:  Lessor  warrants that it has full right to execute and to
perform this Lease and to grant the estate demised and that Lessee, upon payment
of the  required  rents and  performing  the terms,  conditions,  covenants  and
agreements  contained in this Lease,  shall peaceably and quietly have, hold and
enjoy the  Leased  Premises  during  the full term of this  Lease as well as any
extension or renewal  thereof.  Lessor shall not be responsible  for the acts or
omissions of any other Lessee or third party that may  interfere  with  Lessee's
use and enjoyment of the Leased Premises.

18.  LESSOR'S RIGHT OF ENTRY:  Lessor shall have the right,  upon 24 hours prior
notice,  at all reasonable hours, to enter the Leased Premises for the following
reasons: inspection;  cleaning or making repairs; showing the Leased Premises to
prospective  tenants  or  purchasers;  determining  Lessee's  use of the  Leased
Premises,  or  determining  if an act of default  under this Lease has occurred.
Lessee may escort Lessor or its agents while on Lease Premises.

19.  ASSIGNMENT AND SUBLETTING:  (a) Lessor's Rights Lessor shall have the right
to transfer and assign,  in whole or in part, its rights and  obligations in the
Building and property that are the subject of this Lease.

         (b) Lessee's  Restrictions.  (i) without the prior  written  consent of
Lessor,  which  shall not be  unreasonably  withheld,  Lessee may not  sublease,
assign,  mortgage,  pledge,  hypothecate  or  otherwise  transfer  or permit the
transfer of this lease or the  interest of Lessee in this Lease,  in whole or in
part,  by operation  of law or  otherwise.  If Lessee  desires to enter into any
sublease of the Leased Premises,  Lessee shall deliver written notice thereof to
Lessor,  together with financial and other information  sufficient for Lessor to
make an informed judgement with respect to such proposed sublease.  Any approved
sublease  shall be expressly  subject to the terms and conditions of this Lease.
In the event of any assignment or subletting, Lessee shall never the less at all
times  remain  fully  responsible  and  liable  for the  payment of the rent and
compliance with all of its other  obligations under the terms,  provisions,  and
covenants of this Lease. Upon the occurrence of an "Event of Default" as defined
below,  if all or any part of the Leased  Premises are then  assigned or sublet,
Lessor,  in addition to any other remedies provided by this Lease or provided by
law, may at its option,  collect  directly  from the  assignee or









subtenant  all rents  becoming  due to Lessee  by  reason of the  assignment  or
sublease,  and Lessor shall have a security  interest in all  properties  on the
Leased  Premises  to secure  payment of such sums.  Any  collection  directly by
Lessor from the  Assignee or subtenant  shall not be  construed to  constitute a
novation or a release of Lessee from the further  performance of its obligations
under the Lease.

                  (ii) In the event Lessee desires to enter into any sublease of
the Leased  Premises,  Lessor  shall have the option to exclude  from the Leased
Premises  covered  by the  Lease,  the space  proposed  to be sublet by  Lessee,
effective  as of the  proposed  Commencement  Date of  sublease of said space by
Lessee.  Lessor may exercise  said option after  Lessee  notifies  Lessor of the
proposed  sublease.  In the event Lessor  exercises  said  option,  Lessee shall
surrender  possession of the proposed  sublease space to Lessor on the effective
date of exclusion of said space from the Leased Premises  covered by this Lease,
and neither  party  hereto  shall have any further  rights or  liabilities  with
respect to said space under this Lease.

20. DEFAULT BY LESSEE:  The following shall be deemed to be Events of Default by
Lessee under this Lease:

         (a) Delinquent  Rent Lessee shall fail to pay when due any  installment
of rent or any other payment required pursuant to this Lease and such failure to
pay continues for five days from date of notice;

         (b)  Abandonment  Lessee shall abandon any  substantial  portion of the
Leased Premises;

         (c) Other Defaults Lessee shall fail to comply with any term, provision
or covenant of this  Lease,  other than the payment or rent,  and the failure is
not cured within ten (10) days after written notice to Lessee;

         (d) Bankruptcy  Lessee shall file a petition or be adjudged bankrupt or
insolvent under the National  Bankruptcy Act, as amended,  or any similar law or
statute of the United  States or any state;  or a receiver  or trustee  shall be
appointed for all or substantially  all of the assets of Lessee; or Lessee shall
make a transfer in fraud of creditors or shall make an assignment for benefit of
creditors; or

         (e) Liens Lessee shall do or permit to be done any act which results in
a lien being filed against the Leased Premises or the Building and/or Project of
which the Leased Premises are a part.

21. REMEDIES FOR LESSEE'S  DEFAULT:  Upon the occurrence of any event of default
set forth in this Lease,  Lessor shall have the option to pursue any one or more
of the following remedies without any notice or demand:

         (a)  Termination.  Terminate  this Lease,  in which event  Lessee shall
immediately  surrender the Leased Premises to Lessor, and if the Lessee fails to
surrender the Leased Premises, Lessor may, without prejudice to any other remedy
which it may have for  possession  or  arrearages  in rent,  enter upon and take
possession of the Leased Premises, by picking or changing locks if necessary and
lock out,  expel, or remove Lessee and any other person who may be occupying all
or any part of the Leased  Premises  without being liable for prosecution of any
claim for  damages.  Lessee  agrees to pay on demand  the amount of all loss and
damage which Lessor may suffer by reason of the  termination  of the Lease under
this  subparagraph,  whether  through  inability to relet the Leased Premises on
satisfactory terms or otherwise.










         (b) Entry and  Reletting  Enter upon and take  possession of the Leased
Premises by picking or changing lock if necessary, and lock out, expel or remove
Lessee and any other person who may be  occupying  all or any part of the Leased
Premises  without  being  liable for any claim or damages,  and relet the Leased
Premises  on behalf of Lessee  and  receive  directly  the rent by reason of the
reletting.

         (c) Entry and Performing  Lessee's  Obligations.  Enter upon the Leased
Premises,  by picking or changing  locks if necessary,  without being liable for
prosecution or any claim for damages,  and do whatever Lessee is obligated to do
under the terms of this Lease.  Lessee agrees to reimburse  Lessor on demand for
any  expenses  which  Lessor may incur in  effecting  compliance  with  Lessee's
obligations  under this Lease;  further,  Lessee agrees that Lessor shall not be
liable for any  damages  resulting  to Lessee  from  effecting  compliance  with
Lessee's  obligations under this subparagraph  caused by negligence of Lessor or
otherwise.

22.  WAIVER OF  DEFAULT  OR  REMEDY:  Failure  of Lessor to  declare an event of
default  immediately  upon its  occurrence,  or delay in  taking  any  action in
connection  with an event of  default,  shall  not  constitute  a waiver  of the
default,  but Lessor shall have the right to declare the default at any time and
take such action as is lawful or authorized under this Lease. Pursuit of any one
or more of the  remedies  set forth in  Paragraph  21 above  shall not  preclude
pursuit  of any one or more of the other  remedies  provided  elsewhere  in this
Lease or provided by law, nor shall  pursuit of any remedy  provided  constitute
forfeiture or waiver of any rent or damages  accruing to Lessor by reason of the
violation of any of the terms, provisions or covenants of this Lease. Failure by
Lessor to enforce one or more of the remedies  provided upon an event of default
shall not be deemed or construed to constitute a waiver of the default or of any
other violation or breach of any of the terms, provisions or covenants contained
in this Lease.

23.  ACTS OF GOD:  Lessor  shall not be  required  to perform  any  covenant  or
obligation  in this  Lease,  or be liable in damages  to Lessee,  so long as the
performance or non-performance of the covenant or obligation is delayed,  caused
by or prevented by an Act of God or Force Majeure.

24.  ATTORNEY'S  FEES:  Lessee  shall pay upon demand,  all costs and  expenses,
including  reasonable  attorney's  fees,  incurred  by Lessor in  enforcing  the
observance and performance by Lessee of all covenants,  conditions provisions of
this Lease or resulting from Lessee's  default under this Lease. In the event of
default by Lessor,  Lessee  shall be entitled  to  attorney's  fees  required to
enforce any remedies resulting from such default.

25.  SURRENDER OF PREMISES:  Upon  expiration  or  termination  of this Lease or
termination of Lessee's right of possession of the Leased Premises. Lessee shall
vacate the Leased premises.  Lessee shall immediately deliver possession thereof
to Lessor in a clean,  good and  tenantable  condition,  ordinary  wear and tear
accepted.  Upon any  termination  which  occurs other than by reason of Lessee's
default, Lessee shall be entitled to remove from the Leased Premises all movable
personal  property of Lessee's  provided  Lessee  immediately  shall  repair all
damage  resulting  from such  removal and shall  restore the Leased  Premises to
tenantable  condition.  In the event  possession  of the Leased  Premises is not
immediately  delivered  to  Lessor  or if Lessee  shall  fail to  remove  all of
Lessee's movable  property as aforesaid,  Lessor may remove any of such property
therefrom  without any  liability  of Lessor to Lessee or any other  party.  All
movable  property which may be removed from the Leased  Premises by Lessor shall
be  conclusively  presumed to have been  abandoned  by Lessee and title  thereto
shall pass to Lessor without any cost or credit  therefore and Lessor may at its
option and at Lessee's expense, store and/or dispose of such property.









26. HOLDING OVER: In the event of holding over by Lessee after the expiration or
termination of this Lease, the hold over shall be as a tenant at will and all of
the terms and  provisions of this Lease shall be applicable  during that period.
Lessee  shall pay  Lessor as rental  for the  period of such hold over an amount
equal to one and  one-half  (1-1/2) of the rent which would have been payable by
Lessee had the hold over period been a part of the original  term of this Lease.
Lessee agrees to vacate and deliver the Leased  Premises to Lessor upon Lessee's
receipt of notice from Lessor to vacate. The rental payable during the hold over
period shall be payable to Lessor on demand. No holding over by Lessee,  whether
with or without consent of Lessor,  shall operate to extend this Lease except as
otherwise expressly provided.

27. RIGHTS OF FIRST AND SECOND MORTGAGEE:  Lessee accepts this Lease subject and
subordinate  to any  recorded  first and second  mortgage  or deed of trust lien
presently  existing or  hereafter  created upon the Leased  Premises.  Lessor is
hereby irrevocably vested with full power and authority to subordinate  Lessee's
interest under this Lease to any first and second mortgage or deed of trust lien
hereafter  placed on the Leased  Premises,  and  Lessee  agrees  upon  demand to
execute additional  instruments  subordinating this Lease as Lessor may require.
If the  interests of Lessor under this Lease shall be  transferred  by reason of
foreclosure or other proceedings for enforcement of any first or second mortgage
or deed of trust on the Leased Premises, Lessee shall be bound to the transferee
(sometimes  called the `Purchaser'),  at the option of the Purchaser,  under the
terms,  covenants  and  conditions  of this  Lease for the  balance  of the term
remaining,  and any  extensions or renewals with the same force and effect as if
the Purchaser were Lessor under this Lease,  and, if requested by the Purchaser,
Lessee  agrees  to  atone to the  Purchaser,  including  the  first  and  second
mortgagee  under any such mortgage if it be the  Purchaser,  as its Lessor.  The
transfer of any interest of Lessor under this Lease shall not diminish  Lessee's
rights under the Lease as long as it is not in default hereunder.

28. ESTOPPEL CERTIFICATES:  Lessee agrees to furnish promptly from time to time,
upon  request  of Lessor or  Lessor's  mortgagee,  a  statement  certifying,  if
applicable,  that Lessee is in  possession  of the Leased  premises;  the Leased
Premises  are  acceptable;  the Lease is in full force and effect;  the Lease is
unmodified;  Lessee claims no present  charge,  liens or claim of offset against
rent; the rent is paid for the current  month,  but is not prepaid for more than
one month and will not be prepaid for more than one month in  advance;  there is
no existing default by reason of some act or omission by Lessor;  and such other
matters as may be reasonably required by Lessor or Lessor's mortgagee.

29.  SUCCESSORS:  Subject to  Paragraphs  20 and 21 hereof,  this Lease shall be
binding  upon and insure to  benefit  of Lessor and Lessee and their  respective
heirs,  personal  representatives,  successors  and  assigns,  and  if  Lessor's
interest in the Leased Premises cease to exist for any reason during the term of
this lease,  then,  notwithstanding  the  happening  of such  event,  this Lease
nevertheless  shall  remain  unimpaired  and in full force and effect and Lessee
hereunder agrees to atone to the then owner of the Leased Premises.

30. RENT TAX: If applicable in the  jurisdiction  where the Leased  Premises are
situated,  Lessee shall pay and be liable for all rental, sales and use taxes or
other similar taxes,  related to the leased  Premises,  levied or imposed by any
city,  state,  or county  or other  governmental  body  having  authority,  such
payments to be in addition to all other  payments  required to be paid to Lessor
by  Lessee  under  the  terms  of this  Lease.  Any such  payment  shall be paid
concurrently  with the  payment  of the rent upon  which the tax is based as set
forth above.

option  apply such part of the deposit as may be  necessary to cure the default,
and if Lessor does so, Lessee shall upon demand make such additional  deposit as
may be required to maintain the sum of $10,000.00 on hand.  Upon the termination
of this Lease, Lessor shall,  provided the Lessee is not in any default,  refund
to Lessee the balance held by Lessor without interest. In the event of a sale of
the Land and Building of which the Leased premises are a part, Lessor shall have
the right to transfer the deposit and Lessee agrees to look to the new purchaser
solely for the return of said deposit.

State of Ohio.

LEASE,  WITH THE SPECIFIC  REFERENCES  TO WRITTEN  EXTRINSIC  DOCUMENTS,  IS THE

REPRESENTATIONS,   WARRANTIES,   UNDERSTANDINGS,   STIPULATIONS,  AGREEMENTS  OR
PROMISES  PERTAINING TO THIS LEASE OR THE EXPRESSLY  MENTIONED WRITTEN EXTRINSIC
DOCUMENTS NOT INCORPORATED IN WRITING IN THIS LEASE. LESSOR AND LESSEE EXPRESSLY
AGREE THAT  THERE ARE AND SHALL BE NO IMPLIED  WARRANTIES  WHICH  EXTEND  BEYOND
