* Represents less than 1% of the total options granted to our employees in 2001



(1)  Based on an aggregate of 1,801,681 shares subject to options granted by us
     during fiscal year 2001 to employees, consultants and the Named Executive
     Officers.

(2)  Options were granted at an exercise price equal to the greater of the
     closing price of our common stock on Nasdaq on the date of the grant or
     January 2, 2002.

(3)  The 5% and 10% assumed annual rates of compounded stock price appreciation
     are mandated by rules of the Securities and Exchange Commission. We cannot
     assure any Named Executive Officer or any other holder of our securities
     that the actual stock price appreciation over the option term will be at
     the assumed 5% and 10% levels or at any other defined level. Unless the
     market price of our common stock appreciates over the option term, no value
     will be realized from the option grants made to the Named Executive
     Officers. The potential realizable value is calculated by assuming that the
     closing price per share on the date of grant appreciates at the indicated
     rate for the entire term of the option and that the option is exercised at
     the exercise price and sold on the last day of its term at the appreciated
     price. The potential realizable value computation is net of the applicable
     exercise price, but does not take into account applicable federal or state
     income tax consequences and other expenses of option exercises or sales of
     appreciated stock. The values shown do not consider non-transferability or
     termination of the options upon termination of such employee's employment
     with us.

(4)  Pursuant to the terms of Mr. Anderson's separation agreement, these options
     will expire on December 31, 2002 unless sooner exercised.

-------------------------
(1)  2001 Annual Salary Rate reflected in the above table reflects 2001 annual
     salary rate as of December 31, 2001. The table entitled "Summary
     Compensation Table" reflects actual salaries paid in 2001 and includes
     mid-year salary adjustments.


Effective  October 31, 2000,  in  connection  with Mr.  Price's  employment,  we
entered  into an  employment  agreement  with him which  provides for an initial
payment to Mr. Price of $357,624, an annual base salary of $400,000 in the first
year,  $450,000 in the second year,  and $500,000 in the third year, and a bonus
of $200,000 in the first year and a performance bonus of between 25% and 100% of
his  respective  annual base salary for each of the second and third  years.  In
addition,  we granted Mr.  Price  25,000  restricted  shares of our common stock
(which vest in three equal annual  installments  commencing on January 1, 2001),
we granted Mr.  Price an option to purchase  500,000  shares of our stock,  at a
purchase  price of  $12.50  per  share  (which  vests  monthly  over 36  months,
commencing October 30, 2000) and we further agreed to grant Mr. Price additional
options on each  anniversary of the agreement,  in an amount to be determined by
the Board.  We also agreed to reimburse  Mr. Price for all expenses  incurred in
relocating  to the area  with a tax  gross-up  adjustment  and to  extend  him a
$1,500,000 interest-deferred loan for the purchase of a house.

The  agreement  has a three-year  term,  which will  automatically  renew for an
additional three-year period unless either Mr. Price or we give the other notice
of  our/his  intent  not to renew the  agreement.  If we decide not to renew the
agreement,  we must pay Mr.  Price an  amount  such that our net  payment  after
deduction  of all payroll  taxes and all income  taxes at the  highest  marginal
rates  applicable  to Mr. Price will equal the base salary and bonus we paid him
in the third year of the agreement.  Additionally, the expiration for any vested
options will be one year from the  termination of the agreement and all unvested
options will remain unvested and unexercisable.

Either party can terminate the agreement on sixty days' notice.  However, in the
event  there is a change in  control  which  results  in Mr.  Price's  actual or
constructive  termination,  he is entitled to a severance payment equal to twice
the  aggregate of his annual base salary and bonus  payable in the year in which
termination occurs, forgiveness of all outstanding principal and interest on the
interest-deferred  loan, acceleration of the full unvested portion of his 25,000
share  restricted  stock grant and all stock options and an  additional  payment
equal to Mr. Price's maximum total income tax liability  applicable to the total
severance  package.  If Mr.  Price is  terminated  other than for  cause,  he is
entitled to receive a severance  payment  equal to twice his  applicable  annual
base salary and bonus if he is terminated in the first year of the agreement and
equal to his  applicable  annual base salary and bonus if he is  terminated in a
subsequent  year,  forgiveness of all outstanding  principal and interest on the
interest  deferred-loan  and  acceleration  of the full unvested  portion of his
25,000 share restricted stock grant and all stock options.  Additionally,  if he
is  terminated  other  than for cause  prior to the  second  anniversary  of the
agreement,  he is entitled to an additional payment equal the maximum income tax
liability associated with forgiveness of the loan and such additional payment.

We  provided  a  three-year  loan to Dr.  Starr for the  purchase  of his shares
referenced in column four of the table above and to Mr. Denison for the purchase
of 1,300,000 shares of our common stock all of which were purchased  pursuant to
the Founders' Stock Purchase Agreement described below. Each loan bears interest
at a rate of 6%. For each of them, respectively, if his employment is terminated
by us for any  reason,  he has the  right to sell any or all of these  shares of
common stock to us at a price per share equal to the lesser of the  then-current
per share market price of the shares or the original per share purchase price of
$1.00.

Dr.  Brandley's  employment  agreement was originally  with Glyko,  Inc. but was
assigned to us in connection with our acquisition of Glyko, Inc.

Through  June 30,  2000,  Dr.  Starr's  cash  bonus was based on the  difference
between a minimum market capitalization and our quarterly market capitalization.
The cash bonus is calculated as follows:

The Board of Directors  established  a minimum  market  capitalization  of $20.0
million  for the  first  quarter  of 1998.  The  minimum  market  capitalization
increases  by $1.0  million per quarter  until the end of the  agreement  in the
second quarter of 2000. our quarterly market capitalization is calculated at the
end of each  calendar  quarter by  multiplying  the number of our common  shares
outstanding  times the average closing price of our common stock for the last 10
trading  days of the quarter.  If our common  stock is not  publicly  traded the
quarterly market  capitalization  is determined by multiplying the shares of our
common stock  outstanding by the price at which our common stock was sold in the
latest significant  investment by an independent  third-party investor. For each
full $5.0 million that the quarterly market  capitalization  exceeds the minimum
market  capitalization,  Dr. Starr  received a cash bonus of $1,200 in the first
calendar quarter and $1,250 in the second quarter. Dr. Starr's cash bonus is the
sum of the two quarterly bonuses for 2000.

Dr. Starr's total cash bonus was limited to 100% of his base salary in any year.
Additional  amounts beyond the cash limit that may be earned in a year were paid
in stock options using the  Black-Scholes  option pricing model to calculate the
value of the stock option based on period-end parameters.

                                       8


In December 1998, the Board approved a form of  indemnification  agreement to be
entered  into  between  us  and  each  of  our  officers  and  directors.   This
indemnification agreement requires us, among other things, to indemnify officers
and directors  against  liabilities  that may arise by reason of their status or
performance  of their  duties as  officers  or  directors  and to advance  their
expenses  incurred as a result of any  proceeding  against them as to which they
could be indemnified.

Section 162(m)

We have  considered  the  potential  future  effects  of  Section  162(m) of the
Internal  Revenue  Code  on the  compensation  paid to our  executive  officers.
Section 162(m)  disallows a tax deduction for any publicly held  corporation for
individual  compensation  exceeding  $1.0 million in any taxable year for any of
the Named Executive Officers, unless compensation is performance-based.  We have
adopted a policy that, where reasonably practicable, we will seek to qualify the
variable  compensation paid to our executive  officers for an exemption from the
deductibility limitations of Section 162(m).

Director Compensation

Directors do not receive cash  compensation  for their services as our directors
but are reimbursed for their  reasonable  expenses in attending  meetings of the
Board and while  performing  services  for us. In October  2001,  under the 1998
Director Option Plan, we issued to Mr. Denison options to purchase 15,000 shares
of common  stock with an exercise  price set at the fair market  value  (closing
price of common  stock on Nasdaq)  on the date of grant,  which was  $11.40.  In
November 2001,  under the 1998 Director Option Plan, we issued to Messrs.  Sager
and Williams  options to purchase 15,000 shares of common stock with an exercise
price set at the fair market value  (closing price of common stock on Nasdaq) on
the date of grant,  which was $12.00 as consideration for their ongoing services
to us as directors.  In September 2001,  under the 1998 Director Option Plan, we
issued to Dr. Gardner  option to purchase  20,000 shares of common stock with an
exercise  price set at the fair market value  (closing  price of common stock on
Nasdaq) on the date of grant, which was $12.34, as consideration for her initial
year of services to us as a director.

1998 Director Option Plan

The 1998 Director  Option Plan was adopted by the Board in December 1998. It was
approved by our  stockholders  as of January 15, 1999. The plan provides for the
grant of  nonstatutory  stock  options  to  non-employee  directors.  A total of
500,000  shares of our common stock have been  reserved  for issuance  under the
plan.  The plan also  provides  for an annual  increase in this number of shares
equal to the lesser of: (1) 0.5% of our outstanding  capital stock,  (2) 200,000
shares, or (3) a lesser amount determined by the Board.

In fiscal year 2001, options to purchase,  in the aggregate,  65,000 shares were
issued to directors.

The 1998 Director  Option Plan provides that each  non-employee  director  shall
automatically be granted an option to purchase 20,000 shares of our common stock
on the date which that person first becomes a non-employee director. This option
shall have a term of 10 years.  The shares  subject to this initial option shall
vest quarterly over one year. Each  non-employee  director shall thereafter also
be automatically granted an option to purchase 15,000 shares of our common stock
on the first anniversary of the date of their respective initial appointments to
the Board and each anniversary  thereafter,  provided that he or she retains the
Board seat on his or her  anniversary  date.  The shares  subject to this annual
option  shall vest in full one year from the date of grant and shall have a term
of 10 years.  These  options  shall  continue to vest  quarterly  only while the
director serves.  The exercise price per share of each of these options shall be
100% of the fair market  value of a share of our common stock at the date of the
grant of the option.

In the event of a merger or the sale of  substantially  all of the assets of us,
each option may be assumed or  substituted by the successor  corporation.  If an
option is assumed or  substituted,  it shall continue to vest as provided in the
plan.  However,  if a non-employee  director's status as a director of us or the
successor corporation, as applicable, is terminated, other than upon a voluntary
resignation by the non-employee  director,  the option shall immediately  become
fully vested and  exercisable.  If the successor  corporation  does not agree to
assume or  substitute  the option,  each option  shall  become  fully vested and
exercisable  for a  period  of 30 days  from the date  the  Board  notifies  the
optionee of the  option's  full  exercisability,  after which  period the option
shall terminate.

Options granted under the plan must be exercised  within three months of the end
of the optionee's tenure as a director, or within 12 months after termination by
death or  disability,  but in no event later than the expiration of the option's
ten-year term. No option granted under the plan is  transferable by the optionee
other  than by will or the laws of  descent  or  distribution.  Each  option  is
exercisable,  during the lifetime of the optionee, only by the optionee.  Unless
sooner  terminated by the Board, the plan will terminate  automatically 10 years
from the effective date of the plan.

Compensation Committee Interlocks and Insider Participation

None of the members of the  Compensation  Committee is currently or has been, at
any time since our formation, one of our officers or employees. No member of the
Compensation  Committee  serves  as a  member  of  the  board  of  directors  or
compensation  committee  of any entity that has one or more  executive  officers
serving as a member of our board of directors or Compensation Committee.

                                       9


Report of Compensation Committee

The Compensation Committee is responsible for setting general compensation goals
and  operational  guidelines for our personnel,  for setting all elements of the
compensation  of our  executive  officers,  and for  approving  grants  of stock
options. At all meetings of the Compensation Committee in 2001, the Compensation
Committee was composed of the three outside, non-management members of the board
of directors.

Compensation Goals and Policies

The goal of our compensation  policies is to provide compensation  sufficient to
attract,  motivate and retain  executives and staff of  outstanding  ability and
potential.  Compensation  policies  are  intended to  establish  an  appropriate
relationship  between  executive  compensation  and the creation of  stockholder
value as measured by the equity markets. We use the following principles to help
achieve that goal:

         (1) We Provide competitive compensation packages incorporating all
         compensation elements for executives and staff based upon our internal
         policies and compensation packages at similarly situated pharmaceutical
         and biotechnology companies in the San Francisco Bay Area.

         (2) We reward executives and senior staff for outstanding performance
         by the individual and by us.

         (3) We seeks to align the long-term interests of the stockholder and
         the executives and the senior staff through the use of employee stock
         options and other stock priced related compensation, such as our
         Employee Stock Purchase Program.

Considerations for 2001 Compensation

Increases in base salary for 2001 were made  effective  January  2001  primarily
based on our progress and achievements during 2000 and competitive conditions in
the job  marketplace for  biotechnology  expertise in the San Francisco Bay Area
marketplace.

The Compensation  Committee took particular note of 2000 achievements  including
the  initiation of a Phase 3 trial of Aldurazyme and a Phase 1 trial of Aryplase
(formerly  rhASB).  However,  the Compensation  Committee also noted the lack of
corporate activity during the first half of 2000.

Based on the Compensation  Committee's  judgment as to the value of these events
and other less visible internal developments, the Compensation Committee awarded
long-term  compensation stock option grants to our executives and staff.  Except
for Mr.  Price,  who is  covered  under a  separate  employment  agreement,  the
Compensation  Committee  also granted  short-term  incentive  stock options as a
reward for our program in comparison to plan in 2000. Grants under both programs
were pro-rated for the portion of the year that the employee was in our service.

Salary  compensation  for the staff  below  the rank of  officer  was  generally
increased by an average of 5%, which  approximated  the reported  average salary
increase in the  biotechnology  industry in the San Francisco Bay Area and which
was also  pro-rated  for time in  service  during  the  year.  The  Compensation
Committee  deemed  that these  compensation  actions  were  appropriate  for the
progress  made  by  us  in  2000  and  maintained  a  competitive  balance  with
biotechnology companies of similar size and state of development in the region.

With respect to officer salary,  the  Compensation  Committee  determined  that,
based on the factors described above, it was appropriate and elected to increase
salaries by an average of 15%. Additionally,  due to the size of prior grants of
stock options to officers,  the Compensation Committee determined that the prior
option grants  provided the current  officers with  significant  motivation  and
sufficiently  linked their  compensation to our  performance.  The  Compensation
Committee  expressed  concerns  about limiting the  availability  of options for
non-officer   employees   and   possible   dilution  of  current   stockholders.
Accordingly,  the  Compensation  Committee  reduced new option grants to current
officers by an average of one-half.

Chief Executive Officer Compensation

Effective  October 31,  2000,  Mr.  Fredric D. Price was elected by the Board of
Directors to the position of Chief Executive  Officer and Chairman of the Board.
At that time,  the  Compensation  Committee  negotiated a three year  employment
agreement,  which included a competitive compensation package appropriate to Mr.
Price's demonstrated leadership capabilities and achievements.  Mr. Price's base
salary for 2001 was set by this employment  agreement.  Pursuant to the terms of
his employment contract,  Mr. Price was also entitled to a bonus of $200,000 and
an additional  stock option grant to purchase  100,000 shares for his first year
of service.

The terms of Mr. Price's  compensation for 2001 were primarily  determined prior
to his service with us.  However,  the  Compensation  Committee  believes  that,
during  2001,  Mr.  Price  has  amply  demonstrated  that his  skills  merit his
remuneration.  In particular,  the Compensation Committee notes the consummation
of three  financing  facilities,  which  raised more than $156  million in gross
proceeds  for us,  the  acquisition  by us of the  IBEX  pharmaceutical  product
programs and the advancement of two additional  internal  product  programs from
the lab to clinical trials. In light of these accomplishments, and in particular
the follow on public  offering of our common  stock the  Compensation  Committee
awarded Mr. Price an additional bonus of $78,500.

                                       10


The  Compensation  Committee  believes  that the above  authorized  compensation
actions based upon our  achievements  and competitive  compensation  levels will
serve to help retain a highly  qualified  and  motivated  staff led by excellent
senior  management  that is a requirement for our prosperity and the creation of
stockholder value.

Respectfully  submitted  on March 25,  2002 by the  members of the  Compensation
Committee of the board of directors:

     to options or warrants that are exercisable within 60 days of March 31,
     2002 (the "Number of Shares Beneficially Owned") are deemed to be
     outstanding and to be beneficially owned by the person holding the options

Item 13.  Certain Relationships and Related Transactions

Since January 1, 2001,  there has not been nor is there  currently  proposed any
transaction  or series of similar  transactions  to which we were or are to be a
party in which the amount  involved  exceeds  $60,000 and in which any director,
executive  officer,  holder of more than 5% of our common stock or any member of
the immediate  family of any of the foregoing  persons had or will have a direct
or indirect material  interest other than (i) compensation  agreements and other
arrangements,  which are described  elsewhere in this annual report and (ii) the
transaction described below.

Transactions with Directors, Executive Officers and 5% Stockholders

During 2001,  Glyko paid us $7,700 per month in management  fees for  accounting
and related regulatory reporting services.

Indebtedness Of Directors And Executive Officers

Other than as described  below,  none our  directors  or  executive  officers or
associates  of any  director or  executive  officer is, or at any time since the
beginning of the most recently completed fiscal year has been, indebted to us.

In April 2001, pursuant to the terms of the employment  agreement between us and
Fredric D. Price, our Chairman and Chief Executive Officer,  we loaned Mr. Price
$860,000 to purchase a local residential property evidenced by a promissory note
secured by the  property.  The note  matures on October  31,  2004  (subject  to
various  conditions  in the  employment  agreement)  and bears  interest  at the
Federal mid-term rate,  adjusted on December 31 of each year. As of December 31,
2001, this equaled 3.97% per annum, compounded annually.

In February 2002, we loaned $300,000 to Christopher M. Starr, Ph.D. This loan is
evidenced by a promissory note secured by 30,000 otherwise  unencumbered  shares
of our common stock held by Dr. Starr.  The note matures on October 31, 2002 and
bears interest at the rate of 2.74% per annum, the relevant  Applicable  Federal
Rate as of February 2002.

Pursuant to the Stock Purchase  Agreements under which we sold stock ("Founders'
Shares") to two of our founding officers, we have loaned $1,300,000 and $400,000
to Mr.  Denison and Dr. Starr,  respectively,  to purchase  shares of our common
stock.  The loans are  evidenced  by interest  bearing  promissory  notes due on
demand and are fully recourse.

The following  table sets forth any  indebtedness  of our directors or executive
officers entered into in connection with the purchase of the Founders' shares.
