NOTE 1 - PRESENTATION OF INTERIM INFORMATION

As contemplated by the Securities and Exchange Commission under Item 310(b) of
Regulation S-B, the accompanying consolidated financial statements and footnotes
have been condensed and therefore do not contain all disclosures required by
generally accepted accounting principles. It is recommended that these interim
consolidated financial statements be read in conjunction with the consolidated
financial statements and the notes thereto included in the Company's Annual
Report on Form 10-KSB for the year ended December 31, 1998. The interim
financial data are unaudited; however, in the opinion of the management of
Interleukin Genetics, Inc. and subsidiaries (the "Company"), the accompanying
unaudited consolidated financial statements include all adjustments, consisting
only of normal recurring adjustments, necessary to make the interim financial
information not misleading. All significant intercompany transactions and
accounts have been eliminated in consolidation. Results for interim periods are
not necessarily indicative of those to be expected for the full year. Certain
classifications have been made in prior period financial statements to conform
with the current period presentation.

The accompanying financial statements of the Company have been prepared on the
basis of accounting principles applicable to a going concern. Since its
inception, the Company has incurred cumulative net losses of approximately $19.8
million, including losses of approximately $2.6 million during the third quarter
of 1999 and $5.0 million for the nine months ended September 30, 1999.
Additionally, for the nine months ended September 30, 1999, the Company
experienced negative cash flows from operating activities of approximately $3.5
million. As a result of these losses, available cash resources are limited.
These matters raise substantial doubt about the Company's ability to continue as
a going concern. The financial statements do not include any adjustments that
might result from the outcome of these uncertainties. The ability of the Company
to continue as a going concern is dependent upon the Company achieving
significant revenue increases from their existing genetic products, developing
new products, successfully marketing its products to customers at profitable
prices and obtaining significant levels of new capital. If the Company is not
successful in these efforts, the Company would likely be unable to continue
operating as a going concern.

As discussed in footnote 3, the Company issued $5 million of preferred stock
during the second quarter, which generated approximately $4.7 million in net
proceeds. Management is in discussions with a number of potential strategic
partners and, if discussions are successfully completed, believes there should
be up-front funding of some of the Company's development programs. There can be
no assurance that any of the partnering discussions will be completed, or if
such discussions are complete, that there will be up-front funding of the
Company's programs. Management anticipates the current cash resources, absent
additional capital or financings, will be sufficient to conduct its operations
as planned through September 2000.

Commercial success of genetic susceptibility tests will depend upon their
acceptance as medically useful and cost-effective by patients, physicians,
dentists, other members of the medical and dental community, and third-party
payers. It is uncertain whether current genetic susceptibility tests or others
that the Company may develop will gain commercial acceptance on a timely basis.

Research in the field of disease predisposing genes and genetic markers is
intense and highly competitive. The Company has many competitors in the United
States and abroad which have considerably greater financial, technical,
marketing, and other resources available. If the Company does not discover
disease predisposing genes or genetic

                                       4
<PAGE>
markers and develop susceptibility tests and launch such services or products
before their competitors, then revenues may be reduced or eliminated.

The Company's ability to successfully commercialize genetic susceptibility tests
depends on obtaining adequate reimbursement for such products and related
treatment from government and private health care insurers and other third-party
payers. Doctors' decisions to recommend genetic susceptibility tests will be
influenced by the scope and reimbursement for such tests by third-party payers.
If both third-party payers and individuals are unwilling to pay for the test,
then the number of tests performed will significantly decrease, therefore
resulting in a reduction of revenues.

The Company has entered into an arrangement with Sheffield University (the
Agreement) whereby the Company will undertake the development and
commercialization of certain discoveries resulting from Sheffield University's
research. The Agreement with Sheffield University (the University) is a
five-year agreement with an automatic yearly renewal. In accordance with the
Agreement, the Company issued 275,000 shares of common stock to the University
for past research services, the value of which was expensed in the third
quarter. Additionally, each year beginning July 1, 2000, the University will
receive 25,000 stock options at the then current market price, plus 10,000
options for each new patent application filed in the previous 12 months. These
options will be fully vested upon the grant date and have a five-year exercise
period. The Company signed another agreement with the University for research
and development services which automatically renews in one-year increments. Both
agreements can be canceled if the key collaborator leaves the University.

In September 1999, a five-year Consulting Agreement was entered into with the
University's key collaborator. In accordance with the Consulting Agreement, the
key collaborator received 200,000 shares of common stock for past research
services, the value of which was expensed in the third quarter. The key
collaborator will also receive one percent of the first $4 million of net sales
under the PST Technology and two percent for sales above $4 million. Payments
are required 45 days after each quarter end. Beginning July 1, 2000, in
consideration for future services, the key collaborator will receive 25,000
stock options at the then current market price. These options have a five-year
exercise period from the date of grant.

NOTE 2 - EARNINGS PER SHARE

Statement of Financial Accounting Standards (SFAS) No. 128 (SFAS 128), "Earnings
per Share," outlines methods for computing and presenting earnings per share.
SFAS 128 requires a calculation of basic and diluted earnings per shares for all
periods presented. As the Company had losses for the three and nine months ended
September 30, 1999 and 1998, options and warrants have been excluded from the
calculation of the dilutive weighted average shares outstanding as they are
antidilutive in loss periods.

NOTE 3 - EQUITY

Pursuant to a private placement which occurred in June 1999, the Company issued
2,200,000 shares of its Series A Preferred Stock, no par value (Series A Stock),
for $5 million. In conjunction with this offering, the placement agent received
200,000 shares of Series A Stock and a warrant to purchase 1,000,000 shares of
common stock at a price of $0.50 per share. This warrant expires on June 16,
2004. Each share of the Series A Stock was automatically converted into five
shares of the Company's common stock at a conversion price of $0.50 per share
upon the approval of the private placement by the

                                       5
<PAGE>
Company's shareholders on August 20, 1999. The Company filed a Registration
Statement registering the resale of the shares of the common stock underlying
the Series A Stock on July 23, 1999, which was declared effective by the SEC on
September 14, 1999. On the closing date of the private placement, the conversion
price of the Series A Stock was less than the market price of the common stock
which resulted in a beneficial conversion of $5 million. The beneficial
conversion was recorded as common stock and was accreted to preferred stock
ratably from the closing date of the preferred stock to the earliest conversion
date, August 20, 1999.

NOTE 4 - SEGMENT INFORMATION

During 1998, the Company adopted SFAS No. 131 (SFAS 131), "Disclosures about
Segments of an Enterprise and Related Information." SFAS 131 establishes new
standards for reporting information about operating segments in annual and
interim financial statements, requiring that public business enterprises report
financial and descriptive information about its reportable segments based on a
management approach. SFAS 131 also establishes standards for related disclosures
about products and services, geographic areas and major customers. In applying
the requirements of this statement, each of the Company's geographic areas
described below were determined to be an operating segment as defined by the
statement, but have been aggregated as allowed by the statement for reporting
purposes. As a result, the Company continues to have one reportable segment,
which is the development of genetic susceptibility tests and therapeutic targets
for common diseases.

The following table presents information about the Company by geographic area.

Quarterly Report on Form 10-QSB.

GENERAL OVERVIEW

Interleukin Genetics, Inc., a Texas corporation formerly named Medical Science
Systems, Inc. ("ILGN" or the "Company"), develops and commercializes genetic
diagnostic tests and medical research tools. The Company's efforts are focused
on genetic factors that affect the rate of progression of clinical disease
through their influence on common host systems. The Company's first genetic
test, PST(R), a test predictive of risk for periodontal disease, is currently
marketed in the United States, Europe and Israel. Products under development
include tests predictive of risk for osteoporosis, coronary artery disease,
diabetic retinopathy, asthma, pulmonary fibrosis, and meningitis/sepsis.

The Company believes by combining genetic risk assessment with specific
therapeutic strategies, improved clinical outcomes and more cost-effective
management of these common diseases are achieved. ILGN also develops and
licenses its medical research tools, including BioFusion(R), to pharmaceutical
companies. BioFusion, a proprietary enabling system for diagnostic and drug
discovery and development, is a computer modeling system that integrates genetic
and other sub-cellular behavior, system functions, and clinical symptoms to
simulate complex diseases. This system allows

                                       7
<PAGE>
useful information to be derived from rapidly increasing databases of gene
expression being generated in companies and academic centers worldwide.

The Company completed a private placement in June 1999 of $5 million of
preferred stock, with $4.7 million in net proceeds. All of the preferred stock
was converted into common stock upon approval of the private placement by the
shareholders of the Company on August 20, 1999.

The Company is in discussions with a number of potential strategic partners and,
if such discussions are successfully completed, the Company believes this will
result in the up-front funding of some of its programs. There can be no
assurance that any of these discussions will be completed, or if such
discussions are complete, that there will be up-front funding of the Company's
programs.

The Company has followed a strategy of working with strategic partners at the
fundamental discovery stage. This strategy has given the Company access to
discoveries while reducing up-front research expenses. Since 1994, the Company
has had a strategic alliance with the Department of Molecular and Genetic
Medicine at Sheffield University in the United Kingdom (Sheffield). Under this
alliance, Sheffield has provided to the Company the fundamental discovery and
genetic analysis from Sheffield's research laboratories and the Company has
focused on product development, including clinical trials, and the
commercialization of these discoveries. The Company has entered into multiple
joint development and commercialization project agreements with Sheffield, and
anticipates entering into additional collaborative arrangements with Sheffield
and other parties in the future.

During the third quarter of 1999, the Company entered into a new arrangement
with Sheffield. This new arrangement replaced the research and development
agreement that had been in place with Sheffield since 1996. Pursuant to the new
arrangement, the Company issued an aggregate of 475,000 shares of its common
stock to Sheffield and its investigators in exchange for the transfer of certain
patents to the Company and the relinquishment by Sheffield and its investigators
of their respective net proceeds interests under certain agreements with the
Company.

In April 1999, the Company entered into an agreement with Dumex, a subsidiary of
AlPharma, a pharmaceutical manufacturer, to market and sell PST in nine European
countries (Austria, Denmark, Finland, Germany, Ireland, Norway, Sweden,
Switzerland and the U.K.). Dumex is well-known in Europe as a manufacturer of
oral health care products used by periodontists.

In March 1999, the Company entered into an agreement with the Straumann Company,
a leading supplier of dental implants, to market and sell PST in the United
States and Puerto Rico. Straumann launched its PST promotional activities in
April 1999.

In December 1998, the Company signed an agreement with Washington Dental
Service, a member of the Delta Dental Plans Association, for the purchase of
1,200 PST tests. The tests will be used in a study, sponsored by Washington
Dental Service, in collaboration with the University of Washington School of
Dentistry and Interleukin Genetics. The study will provide scientific and
financial information about PST in a reimbursement system. This study is
expected to provide scientific and financial data regarding the use of PST as a
treatment-planning tool to assess risk. The data from the study is anticipated
to be available for analysis in the first quarter of 2000.

                                       8
<PAGE>
In December 1997, the Company entered into an agreement with Medicadent, a
French corporation ("Medicadent"), to market and sell PST in France. In August
1998, the Company entered into an agreement with H.A. Systems, Ltd. to market
and sell PST in Israel. Medicadent commenced offering PST in France in June
1998, and H.A. Systems commenced offering PST in Israel in April 1999. No
assurances can be made regarding the commercial acceptance of PST.

The Company has been awarded four U.S. patents, and has sixteen U.S. patent
applications pending. The U.S. Patent & Trademark Office awarded patents to the
Company for its osteoporosis and periodontal disease susceptibility tests and
two patent awards for its biologic modeling technology called BioFusion(R).
BioFusion is used by the Company in the discovery, development and
commercialization process. The Company's disease susceptibility patents seek to
protect the use of its various genetic markers as an indicator of risk for the
specific disease covered, as well as protecting various therapeutic applications
which these markers may have.

The Company has been  granted a number of  corresponding  foreign  patents and
has filed foreign  counterparts  of its U.S.  applications.  Where the Company
has originally  filed in another  country,  it has filed and plans to continue
to file U.S. and other foreign counterparts.

CURRENT FINANCIAL CONDITION

Since its inception, the Company has incurred cumulative net losses of
approximately $19.8 million including losses of approximately $2.6 million
during the third quarter of 1999 and $5.0 million for the nine months ended
September 30, 1999. As a result of these losses, available cash resources are
limited and will be depleted in September of 2000 absent additional debt or
equity funding or a strategic alliance which provides operating capital. The
ability of the Company to continue as a going concern is dependent upon the
Company achieving significant revenue increases from its existing genetic
products, developing new products, successfully marketing its products to
customers at profitable prices and obtaining significant levels of new capital.
If the Company is not successful in these efforts, the Company would likely be
unable to continue operating as a going concern. See footnote 1 to the Financial
Statements included herein.

SEPTEMBER 30, 1998

Gross revenue for the three months ended September 30, 1999 was $140,179
compared to $107,981 for the same period ended September 30, 1998, an increase
of 30%. In the three months ended September 30, 1999, the Company conducted 429
PST tests compared to 636 tests in the same period in 1998. The results for the
three months ended September 30, 1998, reflect the activity of the Company's
direct sales force during such period. The Company disbanded its sales force and
discontinued its direct marketing efforts in late 1998, and opted to pursue
collaborative partners to market the PST test in lieu of its direct sales force.
Due to the absence of a direct sales force and its marketing partners only just
beginning to market the PST test during the quarter ended September 30, 1999,
the number of PST tests conducted in such quarter were lower than the
corresponding previous year's quarter. Despite the lower number of PST tests
conducted in the third quarter of 1999, gross revenue was higher in the third
quarter of 1999 compared to the year earlier period due to the addition of
revenue from upfront payments by distributors and biological modeling services
in the 1999 quarter. Cost of sales was $79,518 for the three months ended
September 30, 1999 compared to $58,252 for 1998. Gross profit margin was 43% in
the three months ended September 30, 1999 compared to 46% for the year

                                       9

earlier period.  This decrease in gross profit margin reflected higher costs for
sample collection materials associated with the introduction of the new saliva
test kit in the 1999 quarter.

For the three months ended September 30, 1999, the Company had research and
development expenses of $1,764,845 as compared to $513,128 for the third quarter
of 1998. The year-earlier expense was lower due to an abnormally low level of
expenditures during that quarter for clinical trials. Research and development
expense for the three months ended September 30, 1999 included $1,128,125 in
non-cash expense, for the market value of 475,000 shares of common stock issued
to Sheffield University and a consultant for past research and development
services as discussed in footnote 1 to the Financial Statements included herein.

Selling, general and administrative expenses were $936,561 in the third quarter
of 1999 compared to $1,584,922 in the third quarter of 1998, a decrease of
40.9%. This decrease is a result of the Company's ongoing cost-cutting
initiatives, including its strategy to utilize collaborative partners for its
direct sales of its genetic tests. As a result of the Company's effort to reduce
costs, the Company had 14 full-time employees as of September 30, 1999 compared
to 49 one-year earlier.

Interest income in the third quarter of 1999 was $34,944 compared to $74,130 in
the third quarter of 1998. This decrease reflects lower balances of cash in the
third quarter of 1999 compared to the year earlier period, as cash was utilized
throughout 1998 to cover the Company's operating losses. Interest expense of
$9,997 was incurred during the period ended September 30, 1999, compared to
$22,853 in the same period in 1998. The reduction in interest expense was due to
the reduction in the principal amount of the bank debt and lower interest rate
on that debt.

Net loss was $2,612,781 for the third quarter of 1999 compared to a net loss of
$1,999,610 for the third quarter of 1998, an increase of 30.7%, due to the
reasons set forth above. The Company anticipates that it will continue to
experience losses unless its genetic testing revenues grow substantially from
current levels and its efforts to develop revenue from licensing its biologic
modeling research tools are successful. In addition, if the Company is
successful in reaching agreements with strategic partners on developing
additional genetic tests, milestone payments, if any, from these strategic
partners will help cover the Company's research and development expense and
could also reduce the net loss. No assurances can be made that the Company will
be able to increase its revenues, either from genetic tests or licensing
revenue, or that it will be able to reach collaborative partnering agreements.

COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1999 TO NINE MONTHS ENDED
SEPTEMBER 30, 1998


Gross revenue for the nine months ended September 30, 1999 was $362,252 compared
to $269,491 for the same period ended September 30, 1998, an increase of 34%. In
the nine months ended September 30, 1999, the Company conducted 1,343 tests
compared to 1,614 tests in the same period in 1998. The decrease in tests for
the nine months ended September 30, 1999, was due to the lack of a direct sales
force and due to the fact that the Company's two major PST distributors were
just beginning distribution. Cost of sales was $155,635 for the nine months
ended September 30, 1999 compared to $172,344 for 1998. Gross profit margin was
57% in the nine months ended September 30, 1999 compared to 36% for the year
earlier period, reflecting lower unit laboratory costs for the Company's genetic
tests.

                                       10
<PAGE>
For the nine months ended September 30, 1999, the Company had research and
development expenses of $2,865,789 compared to $1,379,860 for the same period of
1998. The higher expense in the first three quarters of 1999 reflects a higher
level of clinical trials in 1999 as well as the $1,128,125 in non-cash expense
for the 475,000 shares of common stock issued to Sheffield University and
consultant.

Selling, general and administrative expenses were $2,339,132 for the nine months
ended September 30, 1999, compared to $5,405,887 in the same period of 1998, a
decrease of 56.7%. This decrease is a result of the Company's ongoing
cost-cutting initiatives, including its strategy to utilize collaborative
partners for its sales of its genetic tests.

Interest income in the nine months ended September 30, 1999, was $79,280
compared to $326,470 in the same period of 1998. This decrease reflects lower
balances of cash in 1999 compared to the year-earlier period, as cash was
utilized throughout 1998 to cover the Company's operating losses. Interest
expense of $50,544 was incurred during the nine month period ended September 30,
1999, compared to $70,278 in the same period in 1998. The reduction in interest
expense was due to the reduction in the principal amount of the bank debt and
lower interest rate on that debt.

Net loss was $4,959,594 for the nine months ended September 30,1999, compared to
a net loss of $6,433,388 for the same period in 1998, a decrease of 22.9%. This
decrease reflects the reduction in sales and marketing expense as the Company
shifts to a collaborative partnering strategy.

LIQUIDITY AND CAPITAL RESOURCES

Pursuant to a $5 million private placement in June 1999, the Company issued
2,200,000 shares of Series A Preferred Stock, no par value, which generated net
proceeds of $4.7 million. Each share of the Series A Preferred Stock converted
into five shares of the Company's common stock upon approval of the private
placement by the Company's shareholders at the Annual Meeting of Shareholders on
August 20, 1999.

Net cash used in operating activities was $3,463,695 during the nine months
ended September 30, 1999 and $6,353,764 during the same period of the prior
fiscal year. As of September 30, 1999, the Company had cash and cash equivalents
of $3,544,508.

The Company currently does not have any commitments for material capital
expenditures. The Company's obligation at September 30, 1999 for capitalized
lease obligations totaled $187,879, of which $110,232 is classified as long-term
and $77,647 is classified as current.

In June 1999 the Company repaid a bank loan which had a principal balance of
$495,358. The Company had provided a $530,000 certificate-of-deposit as security
for this loan, which was released upon the repayment of the loan.

The Company anticipates that its existing cash and cash equivalents, together
with anticipated interest income and revenue, will be sufficient to conduct its
operations as planned until September 30, 2000. However, the Company's future
capital requirements are anticipated to be substantial, and the Company does not
have commitments for additional capital at this time. Such capital requirements
are expected to arise from the commercial launch of additional genetic tests,
continued marketing and sales efforts for PST, continued research and
development efforts, the protection of the Company's intellectual property
rights (including preparing and filing of patent applications), as well

                                       11

as operational, administrative, legal and accounting expenses. THERE CAN BE NO
ASSURANCE THAT THE COMPANY WILL BE ABLE TO RAISE ANY ADDITIONAL NECESSARY
CAPITAL. IF ADDITIONAL AMOUNTS CANNOT BE RAISED, THE COMPANY WOULD SUFFER
MATERIAL ADVERSE CONSEQUENCES TO ITS BUSINESS, FINANCIAL CONDITION AND RESULTS
OF OPERATIONS AND WOULD LIKELY BE REQUIRED TO SEEK PROTECTION UNDER THE UNITED
STATES BANKRUPTCY LAWS. SEE "Current Financial Condition" on page 9 hereof and
Note 1 of the Financial Statements included herein.

The Company's Common Stock is currently listed on The NASDAQ SmallCap Market and
the Boston Stock Exchange. If the Company fails to maintain the qualification
for its Common Stock to trade on the NASDAQ SmallCap Market or the Boston Stock
Exchange, its Common Stock could be subject to delisting. Effective February
1998, the NASDAQ Stock Market announced increases in the quantitative standards,
which require the maintenance of any of (x) $2,000,000 of net tangible assets,
(y) $35,000,000 of market capitalization or (z) $500,000 of net income for two
of the last three years and a minimum bid price per share of $1.00. On February
3, 1999, we received notice from NASDAQ that we were in violation of NASDAQ's
minimum bid price requirement and that if our Common Stock did not have a
closing bid price of at least $1.00 for ten consecutive trading days during the
90-day period ending May 3, 1999, our Common Stock was subject to delisting on
May 3, 1999. The Company believes it satisfied this requirement by having a
closing bid price of at least $1.00 for each trading day since May 7, 1999;
however the Company has not yet received notice from NASDAQ that such
requirement was satisfied. Furthermore, there can be no assurance that our stock
price will maintain such $1.00 minimum bid price. If the market price for our
Common Stock does fall below the $1.00 bid price, our Common Stock could be
subject to delisting from The NASDAQ SmallCap Market.

On April 19, 1999, the Company received notice from the NASDAQ SmallCap Market
that the Company was in violation of NASDAQ's $2,000,000 minimum net tangible
asset requirement. As a result of the private placement completed in June 1999,
management believes that the Company is in compliance with NASDAQ's minimum net
tangible asset requirement; however, the Company has not yet received notice
from NASDAQ that such requirement was satisfied. The Company filed a Current
Report on Form 8-K dated June 25, 1999, containing the Company's pro forma
balance sheet at May 31, 1999, adjusted to reflect the results of the June
private placement. Such balance sheet reflects net tangible assets in excess of
$2,000,000. If the Company is unable to maintain compliance with NASDAQ's
minimum net tangible asset requirement, or maintain a $35,000,000 market
capitalization, the Company would likely be delisted from The NASDAQ SmallCap
Market and may also suffer material adverse consequences to its business,
financial condition and results of operations.

On April 26, 1999, the Company received a letter from NASDAQ expressing concern
regarding the "going concern" opinion of Arthur Andersen LLP, the Company's
independent public accountant, given in Arthur Andersen LLP's report contained
in the Company's Annual Report on Form 10-KSB for the year ended December 31,
1998. While NASDAQ did not notify the Company that its Common Stock was subject
to delisting due to such opinion, NASDAQ does have the discretion to so delist
the Company's Common Stock for any number of reasons, including the "going
concern" opinion of Arthur Andersen LLP. There can be no assurance that the
Company will be able to address this issue in a manner satisfactory to NASDAQ,
or that that the Company's Common Stock will not be delisted from The NASDAQ
SmallCap Market.

                                       12
<PAGE>
On August 3, 1999, the Company received a letter from NASDAQ questioning whether
the Company had violated the shareholder approval provisions of the NASDAQ
Marketplace Rules due to an alleged change-in-control resulting from the private
placement of the Series A Preferred Stock completed by the Company in June 1999.
As a result, NASDAQ is reviewing the Company's eligibility for continued listing
on The NASDAQ SmallCap Market. The Company does not believe that a
change-of-control occurred and has engaged in discussions with NASDAQ to resolve
this matter. There can be no assurance that the Company will be able to address
this issue in a manner satisfactory to NASDAQ, or that the Company's Common
Stock will not be delisted from The NASDAQ SmallCap Market.

If the Company's shares are not listed as intended, trading, if any, would be
conducted in the over-the-counter market in the so-called "pink sheets" or the
OTC Bulletin Board, which was established for securities that do not meet The
NASDAQ SmallCap Market's listing requirements. Consequently, selling the Common
Stock of the Company would be more difficult because smaller quantities of
shares could be bought and sold, transactions could be delayed, and security
analysts' and news media's coverage of the Company may be reduced. These factors
could result in lower prices and larger spreads in the bid and ask prices for
shares of Common Stock. Such NASDAQ delisting would also greatly impair the
Company's ability to raise additional necessary capital through equity or debt
financing.

If the Common Stock of the Company is not listed on The NASDAQ SmallCap Market
and/or the Boston Stock Exchange, it may become subject to Rule 15g-9 under the
Exchange Act. That rule imposes additional sales practice requirements on
broker-dealers that sell low-priced securities to persons other than established
customers and institutional accredited investors. For transactions covered by
this rule, a broker-dealer must make a special suitability determination for the
purchaser and have received the purchaser's written consent to the transaction
prior to sale. Consequently, the rule may affect the ability of broker-dealers
to sell the Common Stock and affect the ability of holders to sell their shares
of Common Stock of the Company in the secondary market.

The SEC's regulations define a "penny stock" to be any equity security that has
a market price less than $5.00 per share or with an exercise price of less than
$5.00 per share, subject to certain exceptions. The penny stock restrictions
will not apply to our shares if they are listed on The NASDAQ SmallCap Market or
the Boston Stock Exchange and we provide certain price and volume information on
a current and continuing basis, or meet required minimum net tangible assets or
average revenue criteria. There can be no assurance that the shares of Common
Stock of the Company will qualify for exemption from these restrictions. If such
shares were subject to the penny stock rules, the market liquidity for the
shares could be adversely affected.

Historically, the Common Stock of the Company has experienced low trading
volumes. The market price of the Common Stock also has been highly volatile and
it may continue to be highly volatile as has been the case with the securities
of other public biotechnology companies. Factors such as announcements by the
Company or its competitors concerning technological innovations, new commercial
products or procedures, proposed government regulations and developments or
disputes relating to patents or proprietary rights may substantially affect the
market price of the Company's securities. Changes in the market price of the
common Stock may bear no relation to the Company's actual operational or
financial results.

YEAR 2000 COMPLIANCE

                                       13
<PAGE>
The efficient operation of the Company's business is dependent on its computer
software programs and operating systems (collectively, "Programs and Systems").
These Programs and Systems are used in several key areas of the Company's
business, including financial reporting, as well as in various administrative
functions. The Company has evaluated its Programs and Systems to identify
potential year 2000 compliance problems, as well as manual processes, external
interfaces with customers, and services supplied by vendors to coordinate year
2000 compliance and conversion. The year 2000 problem refers to the limitations
of the programming code in certain existing software programs to recognize date
sensitive information for the year 2000 and beyond. Unless modified prior to the
year 2000, such systems may not properly recognize such information and could
generate erroneous data or cause a system to fail to operate properly. Based on
current information, the Company believes its Programs and Systems are year 2000
compliant. However, because most computer systems are, by their very nature,
interdependent, it is possible that non-compliant third party computers may not
interface properly with the Company's computer systems. The Company could be
adversely affected by the year 2000 problem if it or unrelated parties fail to
successfully address this issue.

In the event the Company determines following the year 2000 date change that its
Programs and Systems are not year 2000 compliant, the Company will likely
experience considerable delays in compiling information required for financial
reporting and performing various administrative functions. In the event of such
occurrence, the Company's contingency plans call for it to switch vendors to
obtain hardware and/or software that is 2000 compliant, and until such hardware
and/or software can be obtained, the company will plan to use non-computer
systems for its business, including information management services and
financial reporting, as well as its various administrative functions.

Year 2000 Information and Readiness Disclosure Act

To the maximum extent permitted by applicable law, the above information is

The Company is not a party to, nor is its property the subject of, any pending
legal proceeding.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS


      (a) Not applicable

      (b) Not applicable

      (c) On September 30, 1999, the Company approved the issuance of 475,000
shares of common stock, no par value (the "Shares"), to the University of
Sheffield, U.K. (Sheffield) and its investigators in connection with a new
arrangement with Sheffield. This new arrangement replaces the research and
development agreement that had been in place since 1996. In consideration for
the Shares, Sheffield and its investigators relinquished their respective net
proceeds interests under certain agreements with the Company and transferred
certain patents. Under the terms of the new arrangement, the Company is
obligated to grant to Sheffield and its investigators on each July 1 (with the
first options to be granted on July 1, 2000) during the term of the arrangement
options to purchase an aggregate of 50,000 shares of common stock of the Company
and options to purchase an additional 10,000 shares of common stock of the
Company for each patent application filed during the preceding 12 months. These
options are exercisable for a period of five years from the date of grant at an
exercise price to be determined on the applicable grant date. The Shares were
not registered under the Securities Act of 1933, as amended (the "Securities
Act"), pursuant to Section 4(2) of the Securities Act and Regulation D
promulgated thereunder, and pursuant to Rule 903 and Rule 904 of Regulation S.
The Company relied on certain representations and warranties of Sheffield and
its investigators (the "Sheffield Parties"), including, among other things, each
of the Sheffield Parties' ability to evaluate the merits and risks of an
investment in the Shares, each of the Sheffield Parties' status as an
"accredited investor" (as that term is defined in Rule 501(a) of Regulation D),
that each of the Sheffield Parties' residence, domicile and/or principal
corporate office is Sheffield, England and that the Shares were acquired solely
for each of the Sheffield Parties' own account for investment and not with a
view to distribution.

      any other designations, preferences, limitations or relative rights of
      shares of that series.

Any of the designations, preferences, limitations or relative rights (including

relative rights of such series.

      aside for the holders of capital stock ranking senior to the Common Stock

      preferential amounts to which they are respectively entitled, the holders

      remaining assets of the Corporation available for distribution to its
      shareholders.

      his holding shares of any class have any preemptive or preferential right
      to acquire or subscribe for any additional, unissued or treasury shares of
      any class of the Corporation now or hereafter to be authorized, or any
      notes, debentures, bonds or other securities convertible into or carrying
      any right, option or warrant to subscribe to or acquire shares of any
      class now or hereafter to be authorized, whether or not the issuance of
      any such shares, or such notes, debentures, bonds or other securities,
      would adversely affect the dividends or voting or other rights of such
      shareholder, and the board of directors may issue or authorize the
      issuance of shares of any class, or any notes, debentures, bonds or other
      securities convertible into or carrying rights, options or warrants to
      subscribe to or acquire shares of any class, without offering any such

                            San Antonio, Texas 78216

2.    REMOVAL OF DIRECTORS. No director of the Corporation shall be removed from
      such office by vote or other action of the shareholders of the Corporation
      or otherwise, except by the affirmative vote of holders of at least a
      majority of the then outstanding Voting Stock (as defined below), voting
      together as a single class. The term "Voting Stock" shall mean all
      outstanding shares of all classes and series of capital stock of the
      Corporation entitled to vote generally in the election of directors of the
      Corporation, considered as one class; and, if the Corporation shall have
      shares of Voting Stock entitled to more or less than one vote for any such
      share, each reference in the Amended and Restated Articles of
      Incorporation to a proportion or percentage of Voting Stock shall be
      calculated by reference to the portion or percentage of votes entitled to
      be cast by holders of such shares generally in the election of directors
      of the Corporation. Prior to the first date (the "Public Status Date") on
      which the Corporation has outstanding a class of equity securities
      registered under the Securities Exchange Act of 1934, as may be amended
      from time to time (the "Exchange Act"), any such removal of a director of
      the Corporation may be with or without cause. On and after the Public
      Status Date, no director of the Corporation shall be removed from such
      office by vote or other action of the shareholders of the Corporation or
      otherwise, except for cause, which shall be deemed to exist only if: (i)
      such director has been convicted, or such director is granted immunity to
      testify where another has been convicted, of a felony by a court of
      competent jurisdiction (and such conviction is no longer subject to direct
      appeal); (ii) such director has been found by a court of competent
      jurisdiction (and such finding is no longer subject to direct appeal) or
      by the affirmative vote of at least a majority of the Whole Board (as
      defined below) at any regular or special meeting of the board of directors
      called for such purpose to have been grossly negligent or guilty of
      willful misconduct in the performance of his duties to the Corporation in
      a matter of substantial importance to the Corporation; (iii) such director
      has been adjudicated by a court of competent jurisdiction to be mentally
      incompetent, which mental incompetency directly affects his ability to
      perform as a director of tile Corporation; (iv) such director has been
      found by a court of competent jurisdiction (and such finding is no longer
      subject to direct appeal) or by the affirmative vote of at least a
      majority of the Whole Board at any regular or special meeting of the board
      of directors called for such purpose to have breached such director's duty
      of loyalty to the Corporation or its shareholders or to have engaged in
      any transaction with the Corporation from which such director derived an
      improper personal benefit; or (v) "cause" for removal otherwise exists
      under Article 2.32.A. of the Texas Business Corporation Act (the "TBCA").
      No director of the Corporation so removed may be nominated, re-elected or
      reinstated as a director of the Corporation so long as the cause for
      removal continues to exist. The term "Whole Board" shall mean the total
      number of authorized directors of tile Corporation whether or not there
      exist any vacancies in previously authorized directorships. This paragraph
      shall be subject to the rights, if any, of holders of any class or series
      of stock to elect directors and remove directors elected by them.

<PAGE>
                                 ARTICLE EIGHT

            No director of the Corporation shall be liable to the Corporation or
its shareholders for monetary damages for an act or omission in the director's
capacity as a director, except that this article does not eliminate or limit the
liability of a director for: (1) a breach of a director's duty of loyalty to the
Corporation or its shareholders; (2) an act or omission not in good faith that
constitutes a breach of duty of that director to the Corporation or an act or
omission that involves intentional misconduct or a knowing violation of the law;
(3) a transaction from which a director received an improper benefit, whether or
not the benefit resulted from an action taken within the scope of the director's
office; or (4) an act or omission for which the liability of a director is
expressly provided for by an applicable statute.

            If the Texas Miscellaneous Corporation Laws Act or the Texas
Business Corporation Act ("TBCA") is amended to authorize action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the corporation shall be eliminated or limited to the fullest
extent permitted by such statutes, as so amended. Any amendment, repeal or
modification of this Article EIGHT shall be prospective only and shall not
adversely affect any right or protection of a director of the Corporation
existing at the time of such amendment, repeal or modification.

                                  ARTICLE NINE

            On and after the Public Status Date, the vote of shareholders
required for approval of (1) any plan of merger, consolidation, or exchange for
which the TBCA requires a shareholder vote, (2) any disposition of assets for
which the TBCA requires a shareholder vote, (3) any dissolution of the
corporation for which the TBCA requires a shareholder vote, and (4) any
amendment of the Restated Articles of Incorporation of the Corporation for which
the TBCA requires a shareholder vote, shall be (in lieu of any greater vote
required by the TBCA) the affirmative vote of the holders of a majority of the
outstanding Voting Stock entitled to vote thereon, unless any class or series of
shares is entitled to vote as a class thereon, in which event the vote required
shall be the affirmative vote of the holders of a majority of the outstanding
shares within each class or series of shares entitled to vote thereon as a class
and at least a majority of the outstanding Voting Stock otherwise entitled to
vote thereon.

                                  ARTICLE TEN

            Special meetings of shareholders may be called by the Corporation's
chairman of the board, the president or the board of directors. Subject to the
provisions of the Corporation's Amended and Restated Bylaws governing special
meetings, holders of not less than 50% of the outstanding shares of stock
entitled to vote at the proposed special meeting may also call a special

                                      -7-

<PAGE>
meeting of shareholders by furnishing the Corporation with a written request
which states the purpose or purposes of the proposed meeting in the manner set
forth in the Amended and Restated Bylaws.

                                 ARTICLE ELEVEN

            Prior to the Public Status Date, any action required or permitted to
be taken at any annual or special meeting of shareholders of the Corporation may
be taken without a meeting, without prior notice and without a vote, if a
consent or counterpart consents in writing, setting forth the action so taken,
shall be signed by the holder or holders of shares having not less than the
minimum number of votes that would be necessary to take such action at a meeting
at which the holders of all shares entitled to vote on the action were present
and voted. Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those shareholders who
did not consent in writing to the action.

              EXECUTED AND EFFECTIVE this 20th day of August 1999.

Research Steering Committee shall develop an Annual Research Plan which shall
address short and long term focuses and resources to be committed. IL shall have
the right to participate in such research and any such efforts of IL


                                      -5-

<PAGE>
shall be part of the Annual Research Plan. Without first obtaining the written
approval of IL, Sheffield Investigators will not perform additional research in
the Field of Use area (including genetic discovery, functional genetics,
functional biology or clinical studies) for third parties whether pursuant to a
sponsored research agreement, donations or other support or otherwise where the
University cannot transfer all right, title and interest to Innovations within
the Field of Use and related Intellectual Property Rights to IL. Notwithstanding
the above, Sheffield Investigators can: (a) perform whole genome searches for
third parties, but will not perform additional research within the Field of Use
without obtaining written approval of IL, and/or (b) perform research funded by
charities, governmental agencies, or other non-commercial entities within the
Field of Use as long as Sheffield Investigators receive the approval of a
Sheffield appointee of the Research Steering Committee. Sheffield Investigators
will notify IL of all proposed research within the Field of Use. Prior to any
individual beginning work under the Research Program, the University shall
require that such individual execute and sign in substantially similar form the
Sheffield Investigator Agreement attached as Schedule 7 and University shall
notify IL that such individual is added to Schedule 4 as a Sheffield
Investigator.

      4.2 RESEARCH STEERING COMMITTEE. IL and University shall establish a
Research Steering Committee, ("RSC") with a minimum of four members and a
maximum of six members. The RSC shall plan, administer and monitor the Research
Program. In particular, the RSC shall prepare an Annual Research Plan, review
progress in the Research Program and recommend necessary adjustments to the
Research Program as the research takes place. IL and the University each have
the option to appoint up to three members to the RSC. IL initially appoints
Kenneth Kornman, and Philip Reilly. The University initially appoints Gordon
Duff and David Winstanley. Either IL or the University may nominate alternative
or replacement members to serve on the Steering Committee by notice in writing
to the other party, provided, however, Gordon Duff will always serve as one
member of the University's two appointments, representing Sheffield
Investigators, so long as he is an employee of the University. The RSC shall be
chaired by two co-chairpersons, one appointed by IL and one appointed by the
University. The initial Chair for IL shall be Kenneth Kornman and the initial
chair for the University shall be Gordon Duff. The RSC representatives of each
Party shall collectively have one vote on all matters before the RSC. All
decisions of the RSC shall be made by unanimous vote of both parties. The
Steering Committee will meet on a regular basis as the committee members may
determine to be necessary. Written minutes of the meetings of the RSC will be
kept and will be circulated prior to the next meeting for committee members'
approval at the next meeting.

      4.3 PATENT PROSECUTION AND OTHER COSTS. IL will have responsibility for
and control of the preparation and filing in a country of IL's choosing the
patent application with respect to those Innovations within the Field of Use for
which IL determines in its judgment that patent protection should be sought. IL
will have responsibility for the ongoing prosecution of such patent
applications, as well as for the preparation, filing and prosecution of any
corresponding international patent applications. IL will itself bear all costs
for the preparation, filing and prosecution of all patent application for each
such Innovation within the Field of Use including the costs of all corresponding
international patent applications (including but not limited to filing fees,
translation costs and legal fees). Each party will carry out the activities for
which it is


                                      -6-
<PAGE>
responsible at its own expense, including the costs of any research and
development, commercialization costs, internal staff and overhead costs,
consultants and other outside contractors assisting a party in performing its
duties. IL may, in its sole discretion, provide research funding to support work
being performed by Sheffield Investigator(s) in support of its ongoing research
within the Field of Use. Any such research funding will be set forth in a
separate agreement.

5. OWNERSHIP

      5.1 IL INNOVATIONS WITHIN THE FIELD OF USE. IL shall be the sole and
exclusive owner of IL Innovations, and all Intellectual Property Rights in the
foregoing.

      5.2 UNIVERSITY INNOVATIONS WITHIN THE FIELD OF USE. University agrees to
assign to IL all right, title and interest in and to any University Innovations
within the Field of Use and Patents and to all Intellectual Property Rights
therein.

      5.3 JOINT OWNERSHIP. University agrees to assign to IL all right, title
and interest in and to any Joint Innovations within the Field of Use and Patents
and to all Intellectual Property Rights therein.

6. PUBLICATION

      6.1 PUBLICATION. While neither Party wishes in any way to restrict the
academic freedom of those participating in the project, the Parties aim to
prevent publications or statements that adversely affect the commercial interest
of IL. IL agrees that Sheffield Investigators shall be encouraged to present a
symposia, national or regional professional meetings, and to publish in
journals, theses, dissertations, or otherwise of University's own choosing,
methods and results of the Research Program. Before publishing or presenting,
however, Sheffield Investigators and University shall furnish a copy of any
proposed publication or presentation to IL reasonably in advance (preferably at
least six weeks) of the submission of such proposed publication or presentation
to a journal, editor, or other third party. IL shall have one month, after
receipt of said copy, to notify Sheffield Investigator and University of its
objection to such proposed presentation or proposed publication because there is
patentable subject matter or Confidential Information which needs protection. In
the event that IL makes such notification, University shall refrain from making
such publication or presentation for a maximum of 6 months from date of receipt
of such notification in order for IL to file patent application(s) with the
United States Patent and Trademark Office and/or foreign patent office(s)
directed to the patentable subject matter contained in the proposed publication
or presentation and University shall edit such proposed publications or
presentations to remove the material identified by IL as Confidential
Information. Both Parties will strive for consensus before publishing. If a
publication does result, the authors will acknowledge IL's support of the
research in the publications and authorship shall be jointly decided by IL and
University based on accepted scientific practice.


                                      -7-

8. SETTLEMENT OF DISPUTES

      8.1 DISPUTE RESOLUTION. If a dispute arises out of or relates to this
Agreement or its breach (the "Matter"), the Parties agree to resolve the Matter
as follows:

            (a) A Party shall submit written notice of the Matter to the other
Party and request negotiation;

            (b) The Parties shall attempt in good faith to resolve any Matter
arising out of or relating to this Agreement by promptly appointing
representatives with authority to resolve disputes to negotiate the resolution
The designated representatives shall meet as often as necessary during a fifteen
(15) day period (or such other time as the parties may agree) to gather and
furnish to the other all information with respect to the matter in issue which
is appropriate and germane in connection with its resolution. Such
representatives shall discuss the problem and negotiate in good faith in an
effort to resolve the dispute without the necessity of any formal proceeding


                                      -9-

<PAGE>
relating thereto. During the course of such negotiation, all reasonable requests
made by one party to the other for non-privileged information reasonably related
to this Agreement, will be honored in order that each of the parties may be
fully advised of the other's position. The specific format for such discussions
will be left to the discretion of the designated representatives, but may
include the preparation of agreed upon statements of fact or written statements
of position furnished to the other party.

            (c) If the Matter has not been resolved within sixty (60) days of a

to continue to engage DUFF and DUFF agrees to the continuation of that
engagement by IL to provide professional services, as set out in Schedule 1, to
IL relating to the development and the commercial exploitation of Innovations

<PAGE>
engagements, commissions, or positions as advisor, consultant, director,
officer, employee or faculty member on SCHEDULE 2. IL acknowledges that DUFF is

and in such capacity owes primary obligation and allegiance to the University
and that satisfaction of DUFF's respective obligations to the University shall
take precedence without penalty to DUFF over the obligation of DUFF to perform
services under this Agreement. DUFF warrants that (i) DUFF has obtained consent
from the University to perform the Engagement and, (ii) DUFF is able and
entitled to carry out the Engagement without obtaining the consent of any other
third party and without breaching any agreements with any third party.

2.3 Other than the commitments referred to in Section 2.2, DUFF agrees during

Field of Use. These provisions are incorporated herein by this reference. For
any service under the Engagement owned by the University but not covered by the
Research and Technology Transfer Agreement, DUFF will use DUFF's best efforts to
have such intellectual property rights licensed to IL. Such best efforts shall
include but not be limited to obtaining license agreements, and making available
the opportunity to obtain license agreements, for IL on terms which are

Section 4.4 shall survive termination of this Agreement and shall be owed for
life of any issued patent covering the PST technology.

4.5 In consideration for the future services to be performed by DUFF under the
Engagement, IL shall grant to DUFF on an annual basis (with the first options to
be granted on July 1, 2000 and on such date each year thereafter as long as this
Agreement is in effect), options to purchase 25,000 shares of common stock in IL
pursuant to the terms and conditions of the Stock Option Agreement attached as
Schedule 5; provided that the Exercise Price (as defined in the Stock Option
Agreement) of such options shall be equal to the "Current Market Price" (as

Exercise Period (as defined in the Stock Option Agreement) of such options shall
be five years from the applicable annual grant date.

The "Current Market Price" at any date shall mean, in the event the common stock

equity security for the 10 consecutive trading days ending on the trading day
immediately before such date (as adjusted for any stock dividend, split,
combination or reclassification that took effect during such 10 trading day
period). The closing price for each day shall be the last reported sale price
regular way or, in case no such reported sale takes place on such day, the
average of the last closing bid prices regular way, in either case on the
principal national securities exchange on which such equity security is listed
or admitted to trading, or if not listed or admitted to trading on any national
securities exchange, the closing bid price for such day reported by NASDAQ, if
such equity security is traded over-the-counter and quoted in the National
Market System, or if such equity security is so traded, but not so quoted, the
average of the closing bid prices of such equity security as reported by NASDAQ
or any comparable system or, if such equity security is not listed on NASDAQ or
any comparable system, the average of the closing bid prices as furnished by two
members of the National Association of Securities Dealers, Inc., selected in
good faith from time to time by the Board of Directors of IL for that purpose.
If such equity security is not traded in such manner that the quotations
referred to above are available for the period required hereunder, Current
Market Price per share of such equity security shall be deemed to be the fair
value as determined in good faith by the

<PAGE>
Board of Directors of IL, irrespective of any accounting treatment.

4.6 If DUFF fails to carry out the Engagement or any part thereof or is in
breach of any of the terms of this Agreement, IL shall be entitled to withhold
all further payments from DUFF whether or not the same shall have accrued due
and without prejudice to any other rights of IL in respect of such breach;
provided, however, IL shall still be obligated to pay the royalties under
Section 4.04, minus any offset for damages due hereunder.

4.7 As a condition to receiving the option grants described above or prior to
transferring same, all as governed by the terms of the Stock Option Agreement,
the DUFF agrees to execute an investment letter containing representations and
warranties as to investment intent, financial sophistication and ability to bear
the risk of any investment in the options and the common stock underlying same
and such other matters as may be reasonably appropriate and acceptable to IL to
demonstrate compliance with relevant securities and other laws and regulations
before any such issuance of options shall be given effect. Such representations
and warranties may include those contained in or similar to the Subscription
Agreement attached as Schedule 4.

4.8 DUFF covenants that neither DUFF nor its affiliates nor any person acting on
his or their behalf has entered, has the intention of entering or will enter
into any put option, short position or other similar instrument or position
anywhere in the world with respect to the common stock of IL or any security
convertible into or exercisable for the common stock of IL. In addition, DUFF
covenants that neither DUFF nor his affiliates nor any person acting on his or
their behalf has entered, has the intention of entering or will enter into any
other scheme or arrangement for the intended purpose of lowering the price at
which the options to be issued pursuant to this Agreement may be exercised. DUFF
covenants and agrees to inform other relevant parties of the requirements and
restrictions of this section and otherwise contained in the Subscription
Agreement and impose and use it best efforts to enforce such restrictions upon
such persons.

Information") subject to a duty on IL's part to maintain the confidentiality of
such information and to use it only for certain limited purposes. Third Party
Information will be treated as Confidential Information under this Agreement.

5.2 The foregoing provisions of Section 5.01 shall not apply to information
which DUFF demonstrates to IL's reasonable satisfaction:

            (i) is publicly known at the time of disclosure or becomes publicly
known other than through a breach of this Agreement;

            (ii) that was known to DUFF as shown in written records kept in the
ordinary course of business other than under an obligation of confidentiality or
restricted use prior to disclosure by IL;

            (iii) was developed independently by members or students of the
University who are not aware of the content of information disclosed by IL as
shown in written records kept in the ordinary course of business;

<PAGE>
            (iv) was made available by a third party who had a right to do so
and has not imposed any obligation of confidentiality or restricted use in
respect thereof.

            (v) is required to disclose under court or government order, law or
regulation; provided, however, DUFF shall not disclose such information prior to
giving IL reasonable notice to object to such disclosure and then shall only
disclose the information to the extent necessary to comply with such order, law
or regulation.

      5.3 DUFF agrees that:

DUFF shall have the sole responsibility for and control over any persons engaged
to execute the Engagement or to perform any of DUFF's obligations under the
Agreement. All such persons shall be regarded as either principal, agent or
employee of DUFF and neither they nor DUFF shall be regarded as an employee of
IL;

(ii) DUFF may not assign or sub-contract, in whole or in part, any of DUFF's
obligations or rights hereunder without the prior written consent of IL;
(iii) DUFF shall limit the disclosure of the Confidential Information and
Innovations to such of DUFF's principal, agent, employee, or approved assign and
sub-contractor to whom such disclosure is necessary in order to carry out the
Engagement; and

(iv) DUFF shall ensure that such principal, agent, employee, or approved assign
and sub-contractor, acknowledge and are bound by equivalent obligations in
respect to the Confidential Information and the Innovations within the Field of
Use (including any waiver of moral rights) as are undertaken by DUFF in this
Agreement.

5.4 DUFF acknowledges that IL has a proprietary interest in maintaining the
confidentiality of the Confidential Information and undertakes that both during
and for seven years after the termination of this Agreement, DUFF will not
disclose the Confidential Information (except in accordance with Section 5.03)
or use the Confidential Information for any purpose other than to enable DUFF to
carry out the Engagement.

5.5 DUFF hereby acknowledges that any Confidential Information, papers,
documents, drawings, other printed or written matter, samples, computer software
or equipment supplied to DUFF by or on behalf of IL to assist DUFF in the
performance of the Engagement or any such items prepared by or on behalf of DUFF
in connection with the performance of the Engagement are the sole and exclusive
property of IL. DUFF agrees that during the term of this Agreement, DUFF will
not remove any IL materials from the business premises of IL or deliver any IL
materials to any person or entity outside IL, without the written permission of
an officer of IL. DUFF undertakes to return all such items to IL on completion
of the Engagement or such earlier date as IL may require together with any
copies thereof which may then be in DUFF's possession.

6. PROPRIETARY PROPERTY ASSIGNMENT

6.1 Any Innovations within the Field of Use made, conceived or developed alone
or jointly by DUFF or DUFF's principal, agent, employee, approved assign,
sub-contractor or others in connection with the performance of services
hereunder during the Term and for six months thereafter shall be governed by the
terms of the Research and Technology Transfer Agreement, and all Innovations
within the Field of Use including that made, conceived or developed in
performance of DUFF's duties as an employee of University shall be promptly
reported in writing to IL. To the extent the services resulted in an innovation
that was outside the Field of Use, then DUFF shall assign all his rights in such
innovations to IL; provided, however, if such rights are required to be assigned
to the University, DUFF shall assign those rights to the


<PAGE>
University and shall comply with Section 2.06. DUFF shall not use the
Innovations for DUFF's own purposes nor disclose it to or use it for any third
party without the prior written approval of IL. At all times before or after
completion of the Engagement, IL shall have the right to examine the results and
any materials relating thereto to ensure IL compliance with the provisions of
this Agreement.

6.2 DUFF will assist IL in every proper way to obtain and from time to time to
enforce IL's United States and foreign intellectual property rights emanating
from this Agreement in any and all countries. To that end, DUFF, without charge
to IL, other than the reimbursement to DUFF by IL of reasonable out-of-pocket
costs, shall execute, acknowledge and deliver to IL all such further papers,
including any patent and design applications, assignments, copyrights, any
waiver of moral rights and other legal instruments as may be reasonably
requested by IL and necessary to enable IL to protect any innovations developed
hereunder by patent or otherwise in any and all countries, and shall render all
such assistance as IL may require in any patent office, litigation (including
appearance as a witness) or other proceeding involving said innovations.

6.3 DUFF shall ensure that DUFF's principal, agent, employee and approved assign
or sub-contractor shall cooperate fully to enable DUFF to vest all rights in the
innovations in IL including executing any patent or design applications or
assignments and any other legal instruments and doing any other things which IL
deems necessary to establish or protect its rights in the innovations.

6.4 DUFF, as part of the services to be performed hereunder, shall keep written
records of DUFF's work, properly witnessed for use as invention records, and
shall submit such records to IL when requested or at the termination of DUFF's
services hereunder. DUFF shall not, except at the direction of IL, or as
otherwise permit hereunder, reproduce, in whole or in part, any of said written
notebook records. DUFF shall provide to IL in a timely fashion all written or
tangible materials and deliverables resulting from DUFF's work under this
Agreement.

6.5 DUFF's obligations under this Article 6 shall survive termination of this
Agreement, regardless of how this Agreement is terminated.

7. PUBLICATION PROCEDURES

7.1 A. While neither Party wishes in any way to restrict the academic freedom of
those participating in the project, the Parties aim to prevent publications or
statements which adversely affect the commercial interest of IL. IL agrees that
DUFF shall be encouraged to present a symposia, national or regional
professional meetings, and to publish in journals, theses, dissertations, or
otherwise of DUFF's own choosing, methods and results of the Engagement. Before
publishing or presenting, however, DUFF shall furnish a copy of any proposed
publication or presentation to IL reasonably in advance (preferably at least 6
weeks) of the submission of such proposed publication or presentation to a
journal, editor, or other third party. IL shall have one month, after receipt of
said copy, to notify DUFF of its objection to such proposed presentation or
proposed publication because there is patentable subject matter or Confidential
Information which needs protection. In the event that IL makes such
notification, DUFF shall refrain from making such publication or presentation
for a maximum of 6 months from date of receipt of such notification in order for
IL to file patent application(s) with the United States Patent and Trademark
Office and/or foreign patent office(s) directed to the patentable subject matter
contained in the proposed publication or presentation and DUFF shall edit such
proposed publications or presentations to remove the material identified by IL
as Confidential Information. Both Parties will strive for consensus before
publishing. If a publication does result from the Engagement, the authors will
acknowledge IL's support of the research in the publications and authorship
shall be jointly decided by IL and DUFF based on accepted scientific practice.
The parties acknowledge that emergency situations may arise where DUFF is
attempting to meet a deadline. The Parties will attempt to accommodate such
deadlines as long as all patentable subject matter or Confidential Information
is protected.

<PAGE>
B. IL shall have the right to use the data generated in this Engagement in
filing patent applications, in filing for regulatory approvals and for any other
commercial purposes.

8. WARRANTIES

8.1 During DUFF's work with IL DUFF will not improperly use or disclose any
confidential information or trade secrets, if any, of any former employer or any
other person to whom DUFF has an obligation of confidentiality, and DUFF will
not bring onto the premises of IL any unpublished documents or any property
belonging to any former employer or any other person to whom DUFF has an
obligation of confidentiality unless consented to in writing by that former
employer or person. DUFF will use in the performance of duties only information
which is generally known and used by persons with training and experience
comparable to DUFF's, which is common knowledge in the industry or otherwise
legally in the public domain, or which is otherwise provided or developed by IL.

8.2 DUFF represents that performance of all the terms of this Agreement and the
Engagement by IL does not and will not breach any agreement to keep in
confidence information acquired by DUFF in confidence or in trust prior to this
Agreement. DUFF has not entered into, and agrees to not enter into, any
agreement either written or oral in conflict herewith, except for Schedule 2.

8.3 Except as provided herein, IL shall hold harmless and indemnify DUFF against
any and all liabilities, costs, damages, expenses and attorney fees resulting
from or attributable to any and all acts or omissions of DUFF relating to or
arising out of DUFF's Engagement with IL provided that DUFF has acted in good
faith and in a manner which DUFF reasonably believed to be in, or not opposed
to, the best interests of IL. Except as provided herein, DUFF shall not be
required to indemnify or reimburse IL or any insurer for any such liabilities,
costs, damages, expenses and attorneys' fees, relating to or arising out of
actions of DUFF undertaken in good faith and in a manner which DUFF reasonably
believed to be in, or not opposed to, the best interests of IL.

9. LEGAL AND EQUITABLE REMEDIES

9.1 Because DUFF's services are personal and unique and because DUFF may have
access to and become acquainted with the Confidential Information of IL, IL
shall have the right to enforce this Agreement and any of its provisions by
injunction, specific performance or other equitable relief, without bond and
without prejudice to any other rights and remedies that IL may have for a breach
of this Agreement.

10. DISPUTE RESOLUTION

10.1 If a dispute arises out of or relates to this Agreement or its breach (the
"Matter"), the Parties agree to resolve the Matter as follows:

(i) A Party shall submit written notice of the Matter to the other Party and
request negotiation;

(ii) The Parties shall attempt in good faith to resolve any Matter arising out
of or relating to this Agreement promptly by negotiation between representatives
which the Parties may appoint;

(iii) If the Matter has not been resolved within sixty (60) days of a Party's
request for negotiation, either Party may request that the Matter be submitted
to a sole mediator selected by the Parties for a mandatory one (1) day
mediation; and

(iv) If the Matter has not been resolved by such mediation, either Party may
submit the Matter for binding

<PAGE>
arbitration in accordance with the Commercial Rules of the American Arbitration
Association ("AAA"). The panel shall be selected from the AAA's large complex
case panel, provided, however, if this panel is of insufficient size to pick the
arbitrator(s), then the regular commercial panel shall be used to pick any
additional arbitrator(s).

(v) The award shall be made within six (6) months of selection of an
arbitrator(s).

      The mediation and arbitration shall be held in San Antonio, Texas, U.S.A.
or other mutually agreed location. The Parties, their representatives, the
mediator and the arbitrator shall hold the existence, content and results of any
negotiation, mediation or arbitration in confidence unless disclosure is
required by law or regulation, and in such case the Parties shall take
reasonable precautions to only disclose what is required by law or governmental
regulation.

      Any award of the Arbitration shall be binding on the Parties and shall be
enforceable in any court having jurisdiction over the Party from whom
enforcement is requested.

10.2 If the dispute resolution procedure of this ARTICLE 10 is not instituted by
submission of written notice under Section 10.01(i) within three (3) years of
the Party's first knowledge of a Matter or is not diligently pursued, then such
Party waives its rights to seek a remedy for such Matter.

11. MISCELLANEOUS

11.1 This Agreement shall be binding upon and shall inure to the benefit of the
heirs, legal representatives, administrators, successors and licensees of the
Parties hereto. Neither Party may make any assignment of its rights or
obligations under this Agreement without the prior written consent of the other
Party hereto.

11.2 This Agreement shall be deemed to have been made under, and shall be
construed and interpreted in accordance with the laws of the state of Texas,
U.S.A. No conflicts-of-law rule or law which might refer such construction and
interpretation to the laws of another state, republic, or country shall be
considered. Any national law, United Nations treaty or convention, or law
arising from any international treaty is hereby waived in favor of the
application of Texas law. The Parties hereby specifically exclude the
application of The Convention for the International Sale of Goods. All questions
concerning the construction or effect of patent right shall be construed in
accordance of the laws of the country granting those rights. All disputes
arising in connection herewith shall be resolved by the dispute resolution
procedure of Article X. If either Party seeks an injunction, equitable relief or
enforcement of the arbitrator such action shall be submitted to the exclusive
jurisdiction of the courts in San Antonio, Texas, U.S.A. and both Parties agree
to submit to the jurisdiction of such courts.

11.3 Both Parties hereby especially agree in contract that neither Party intends
to violate any public policy, statutory or common law, rule, regulation, treaty
or decision of any government agency or executive body thereof of any country or
community or association of countries; that if any word, sentence, paragraph or
clause or combination thereof of this Agreement is found, by a court or
executive body with judicial powers having jurisdiction over this Agreement or
any of its Parties hereto, in a final unappealed order to be in violation of any
such provision in any country or community or association of countries, such
words, sentences, paragraphs or clauses or combination shall be inoperative in
such country or community or association of countries, and the remainder of this
Agreement shall remain binding upon the Parties hereto.

11.4 The Parties covenant and agree that if either Party fails or neglects for
any reason to take advantage of any of the terms provided for the termination of
this Agreement or if either Party, having the right to declare this Agreement
terminated, shall fail to do so, any such failure or neglect by either Party
shall not be a waiver or be deemed or be construed to be a waiver of any cause
for the termination of this

<PAGE>
Agreement subsequently arising, or as a waiver of any of the terms, covenants or
conditions of this Agreement or of the performance thereof. None of the terms,
covenants and conditions of this Agreement can be waived by either Party except
by its written consent.

11.5 This Agreement is the final, complete and exclusive agreement of the
Parties with respect to the subject matter hereof and supersedes and merges all
prior discussions between IL and DUFF. No modification of or amendment to this
Agreement, or any waiver of any rights under this Agreement, will be effective
unless in writing and signed by the Party to be charged. Any subsequent change
or changes in DUFF's duties, salary or compensation will not affect the validity
or scope of this Agreement. As used in this Agreement, the period of the
Engagement includes any time during which DUFF may be retained by IL as an
employee.

11.6 Neither Party hereto shall originate any publicity, news release or other
public announcements, written or oral, whether to the public press or otherwise,
relating to this Agreement, to any amendment hereto or to either Party's
performance hereunder, without the prior written approval of the other Party,
which approval shall not be unreasonably withheld.

11.7 All covenants and obligations of DUFF under this Agreement shall survive
the termination of this Agreement.

11.8 Any notice required or permitted to be given under this Agreement shall be
delivered by hand or sent by recorded delivery, post, cable, telex, facsimile
copy or electronic mail to each Party at the address stated in this Agreement or
such other address as may be notified for this purpose from time to time. Any
notice so sent shall not be deemed to have been given until it has been received
by the Party to whom it has been addressed.

11.9 DUFF specifically agrees to pay all federal and state self-employment and
other income taxes, social security taxes, disability and unemployment or other
employment related taxes. DUFF shall assume full responsibility for the payment
of all taxes with respect to the equity, cash or other payments made to him
under this Agreement; provided, however, IL may withhold from any compensation
payable to DUFF under this Agreement all federal, state, city or other taxes as
may be required pursuant to any law or governmental regulation or ruling.

11.10 This Agreement may be executed in any number of counterparts, each of
which shall be deemed an original but all of which together shall constitute one
and the same instrument.

11.11 Each Party acknowledges that it and its counsel have received and reviewed
this Agreement and that normal rules of construction, to the effect that
ambiguities are to be resolved against the drafting Party, shall not apply to
this Agreement or to any amendments, modifications, schedules, exhibits or
attachments to this Agreement.

11.12 Each Party is responsible for its own expenses related to the preparation
and execution of this Agreement.


      IN WITNESS WHEREOF, DUFF and IL have hereunto executed this Agreement in
multiple originals by their duly authorized officers and representatives
effective as of the date first set forth above.
