PINNACLE PROPERTIES MANAGEMENT, INC.
STANDARD FORM
COMMERCIAL LEASE


In consideration of the covenants herein contained, 6-8 PRESTON COURT, L.L.C., a
Delaware limited liability company, ("LESSOR"), does hereby lease to Asiana
Pharmaceuticals Corporation, a Delaware corporation ("LESSEE"), the following
described premises, (the "leased premises"): approximately 4,000 square feet as
depicted on Exhibit "A" located at 8-A Preston Court, Bedford, MA 01730 to have
and hold the leased premises for a term of five (5) years commencing at noon on
June 1, 1999 and ending at noon on May 30, 2004 unless sooner terminated as
herein provided. LESSOR and LESSEE now covenant and agree that the following
terms and conditions shall govern this lease during the term hereof and for such
further time as LESSEE shall hold the leased premises.

1. RENT. LESSEE shall pay to LESSOR base rent of seventy-one thousand eight
hundred U.S. Dollars ($71,800.00) per year, drawn on a U.S. Bank, in monthly
installments of $5,983.33 payable on the first day in each calendar month in
advance, without demand or any right of set-off or deduction whatsoever, the
first monthly payment to be made upon LESSEE's execution of this lease,
including payment in advance of appropriate fractions of a monthly payment for
any portion of a month at the commencement or end of said lease term. All
payments shall be made to LESSOR or LESSOR's agent: 6-8 Preston Court, L.L.C.
c/o Pinnacle Properties Management Inc., 3740 Beach Blvd., Suite 306,
Jacksonville, FL 32207, or at such other place as LESSOR shall from time to time
in writing designate. The amount of base rent due during each calendar year of
this lease and any extensions thereof shall be annually increased by the
increase in the "Cost of Living" as shown by the Consumer Price Index (Boston,
Massachusetts, All Items, All Urban Consumers), United States Department of
Labor, Bureau of Labor Statistics (the "Index"). All such adjustments shall take
place with the rent due on January 1 of each year during the lease term. The
base month from which to determine the amount of each increase in the Index
shall be January 1999, which figure shall be compared with the figure for
November 1999, and each November thereafter to determine the percentage increase
(if any). The increase will be multiplied by the base rent to determine the
increased base rent (if any) to be paid during the following calendar year. In
the event that the Consumer Price Index as presently computed is discontinued as
a measure of "Cost of Living" changes, any adjustment shall then be made on the
basis of a comparable index then in general use as selected by LESSOR.

2. SECURITY DEPOSIT. LESSEE shall pay to LESSOR a security deposit in the amount
of eleven thousand eight hundred dollars ($11,800.00) upon the execution of this
lease by LESSEE, which shall be held, as security for LESSEE's performance as
herein provided and refunded to LESSEE without interest at the end of this lease
subject to LESSEE's satisfactory compliance with the conditions hereof. LESSEE
may not apply the security deposit to payment of any rent. In the event of any
default or breach of this lease by LESSEE, LESSOR may apply the security deposit
first to any unamortized improvements completed for LESSEE's occupancy, then to
offset any outstanding invoice or other payment due to LESSOR, with the balance
applied to outstanding rent. If all or any portion of the security deposit is
applied to cure a default or breach during the term of the lease, (i) such
application of the security deposit shall not constitute a waiver of such
default or deprive LESSOR of any other remedy LESSOR may have

<PAGE>


on account of such default, and (ii) LESSEE shall be responsible for immediately
restoring said deposit to its full original amount and failure to do so shall be
considered a substantial default under this lease. LESSEE's failure to remit the
full security deposit or any portion thereof when due shall also constitute a
substantial lease default. LESSOR may deliver the Security Deposit to the
purchaser of LESSOR's interest in the leased premises in the event such interest
is sold, and thereupon LESSOR shall be discharged from any further liability
with respect to such Security Deposit.

3. USE OF PREMISES. LESSEE shall use the leased premises only for the purpose of
executive and administrative offices, research & development, and storage.

4. ADDITIONAL RENT AND TAX ESCALATION. LESSEE shall pay to LESSOR as additional
rent per annum ("Additional Rent") a proportionate share (9.02%) of any increase
in the Operating Costs (defined below) in the building (including the related
land, driveways, parking facilities, and similar improvements) of which the
leased premises are a part (hereinafter called the building), for a given
calendar year over the actual Operating Costs in the building for the calendar
year 1999 (the "Operating Expense Stop"). LESSOR may collect such amount in a
lump sum, which shall be due within thirty (30) days after LESSOR furnishes to
LESSEE the Operating Costs and Tax Statement (defined below). Alternatively,
LESSOR may make a good faith estimate of the Additional Rent to be due by LESSEE
for any calendar year or part thereof during the lease term, and LESSEE shall
pay to LESSOR at the commencement of the lease and on the first day of each
calendar month thereafter, an amount equal to the estimated Additional Rent for
such calendar year or part thereof divided by the number of months therein. From
time to time, LESSOR may estimate and re-estimate the Additional Rent to be due
by LESSEE and deliver a copy of the estimate or re-estimate to LESSEE.
Thereafter, the monthly installments of Additional Rent payable to LESSEE shall
be appropriately adjusted in accordance with the estimations so that, by the end
of the calendar year in question, LESSEE shall have paid all of the Additional
Rent as estimated by LESSOR. Any amounts paid based on such an estimate shall be
subject to adjustment as herein provided when actual Operating Costs are
available for each calendar year. The term "Operating Costs" shall mean all
expenses and disbursements that LESSOR incurs in connection with the ownership,
operation, and maintenance of the building including, but not limited to, the
following costs: a) wages and salaries (including management fees) of all
employees engaged in the operation, maintenance, and security of the building,
including taxes, insurance, and benefits relating thereto; b) all supplies and
materials used in the operation, maintenance, repair, replacement, and security
of the building; c) costs for improvements made to the building which, although
capital in nature, are expected to reduce the normal operating costs of the
building, as well as capital improvements made in order to comply with any law
hereafter promulgated by any governmental authority, as amortized over the
useful economic life of such improvements as determined by LESSOR in its
reasonable discretion; d) cost of all utilities, except the cost of utilities
reimbursable to LESSOR by the building's tenants; e) insurance expenses; f)
repairs, replacements, and general maintenance of the building; and g) service
or maintenance contracts with independent contractors for the operation,
maintenance, repair, replacement, or security of the building (including,
without limitation, alarm service, window cleaning, and elevator maintenance).

LESSEE shall also pay to LESSOR as additional rent a proportionate share (9.02%)
(based on square footage leased by LESSEE as compared with the total leasable
square footage of the

<PAGE>


building) of any increase in the Taxes ("Tax Escalation") levied against the
land and building. LESSEE shall pay the Tax Escalation in the same manner as
provided above for Additional Rent with regard to Operating Costs. The base from
which to determine the amount of any increase in taxes shall be the rate and the
assessment in effect as of fiscal year 1999 ("Real Estate Tax Stop"). `Taxes"
shall mean taxes, assessments, and governmental charges whether federal, state,
county or municipal, and whether they be by taxing districts or authorities
presently taxing or by others, subsequently created or otherwise, and any other
taxes and assessments attributable to the building (or its operation),
excluding, however, penalties and interest thereon and federal and state taxes
on income (if the present method of taxation changes so that in lieu of the
whole or any part of any Taxes, there is levied on LESSOR a capital tax directly
on the rents received therefrom or a franchise tax, assessment, or charge based,
in whole or in part, upon such rents for the building, then all such taxes,
assessments, or charges, or the part thereof so based, shall be deemed to be
included within the term "Taxes" for purposes hereof).

By April 1 of each calendar year, or as soon thereafter as practicable, LESSOR
shall furnish to LESSEE a statement of Operating Costs and Taxes for the
previous year (the "Operating Costs and Tax Statement"). With respect to any
calendar year or partial calendar year in which the building is not occupied to
the extent of 95% of the leasable area thereof, the Operating Costs for such
period shall, for the purposes hereof, be increased to the amount which would
have been incurred had the building been occupied to the extent of 95% of the
rental area thereof. If the Operating Costs and Tax Statement reveals that
LESSEE paid more for Operating Costs than the actual Additional Rent and more
for Taxes than Tax Escalation for the year for which such statement was
prepared, then LESSOR shall promptly credit LESSEE for such excess; likewise, if
LESSEE paid less than the actual Additional Rent or Tax Escalation due, then
LESSEE Shall promptly pay LESSOR such deficiency, within thirty (30) days after
receiving notice from LESSOR of the amount of such deficiency.

5. UTILITIES. LESSEE may utilize the existing equipment serving the leased
premises to heat the leased premises in season and cool all office areas between
May 1 and November 1. LESSEE shall pay all charges for utilities used on the
leased premises, including electricity, gas, oil, water, and sewer. LESSEE shall
pay the utility provider or LESSOR, as applicable, for all such utility charges
as determined either by separate meters serving the leased premises or as a
proportionate share of the utility charges as determined by LESSOR if not
separately metered. LESSEE shall also pay LESSOR a proportionate share of any
other fees and charges relating in any way to utility use at the building. No
plumbing, construction or electrical work of any type shall be conducted by
LESSEE or its agents without LESSOR's prior written approval and LESSEE
obtaining the appropriate municipal permit.

6. COMPLIANCE WITH LAWS. LESSEE acknowledges that no trade, occupation, activity
or work shall be conducted in the leased premises or use made thereof which may
be unlawful, improper, noisy, offensive, or contrary to any applicable statute,
law, regulation, restriction, ordinance or bylaw. LESSEE shall keep all
employees working in the leased premises covered by Worker's Compensation
Insurance and shall obtain any licenses and permits necessary for LESSEE's
occupancy. LESSEE shall comply with all Federal, state, municipal and other
laws, ordinances, rules and regulations applicable to the leased premises and
the business conducted therein and LESSEE shall comply with the rules and
recommendations of landlord's insurance carriers. Any cost for alterations.
additions or improvements required to

<PAGE>


modify the common areas of the building in conjunction with any applicable law,
regulation, including the Americans With Disabilities Act, shall be paid by
LESSOR. Such alterations, additions, or improvements shall be made in the sole
discretion of LESSOR. Any alterations, additions or improvements required to
modify the leased premises in conjunction with any law or regulation, including
the American's With Disabilities Act, shall be approved by LESSOR and paid by
LESSEE.

7. FIRE, CASUALTY, EMINENT DOMAIN. Should a substantial portion of the leased
premises, or of the property of which they are a part, be substantially damaged
by fire or other casualty, or be taken by eminent domain, LESSOR may elect to
terminate this lease. When such fire, casualty, or taking renders the leased
premises substantially unsuitable for their intended use, a just and
proportionate abatement of rent shall be made, and LESSEE may elect to terminate
this lease if: (a) LESSOR fails to give written notice within thirty (30) days
of such fire, casualty or taking of its intention to restore the leased
premises, or (b) LESSOR fails to restore the leased premises to a condition
substantially suitable for their intended use within one hundred eighty (180)
days of said fire, casualty or taking. LESSOR reserves all rights for damages or
injury to the leased premises for any taking by eminent domain and LESSEE shall
release the entire condemnation award, and LESSEE hereby assigns to LESSOR all
of LESSEE's interest therein.

8. FIRE INSURANCE. LESSEE shall not permit any use of the leased premises which
will adversely affect or make voidable any insurance on the property of which
the leased premises are a part, or on the contents of said property, or which
shall be contrary to any law or regulation from time to time established by the
Insurance Services Office (or successor), local Fire Department, LESSOR's
insurer, or any similar body. LESSEE shall on demand reimburse LESSOR, and all
other tenants, all extra insurance premiums caused by LESSEE's use of the leased
premises. LESSEE shall not vacate the leased premises or permit same to be
unoccupied other than during LESSEE's customary non-business days or hours.

9. MAINTENANCE OF PREMISES. LESSOR will be responsible for all structural and
roof maintenance of the leased premises but specifically excluding damage caused
by the careless, malicious, willful, or negligent acts of LESSEE or others,
chemical, water or corrosion damage from any source, and maintenance of the
space heating, ventilating, and cooling units exclusively serving the leased
premises (collectively, the "HVAC Unit") and of any non "building standard"
leasehold improvements.

LESSOR shall not be deemed to have breached its obligation to make the repairs
required to be made by LESSOR unless LESSOR fails to make the same within a
reasonable period (taking into consideration the type of repair involved) after
receiving written notice from LESSEE of the need therefor. LESSEE agrees to
maintain at its expense the HVAC Unit and all other aspects of the leased
premises in the same condition as they are at the commencement of the term or as
they may be put in during the term of this lease, normal wear and tear and
damage by fire or other casualty only excepted, and whenever necessary, to
replace light bulbs, plate glass and other glass therein, acknowledging that the
leased premises are now in good order and the light bulbs and glass whole. If
LESSOR so directs, LESSEE shall enter into a preventive maintenance/service
contract acceptable to LESSOR with a maintenance contractor acceptable to LESSOR
at LESSEE's sole cost and expense for servicing all air conditioning, heating,

<PAGE>


ventilating, and other equipment or other equipment located within or serving
the leased premises. LESSEE will properly control or vent all solvents,
degreasers, smoke, odors, etc. and shall not cause the area surrounding the
leased premises to be in anything other than a neat and clean condition,
depositing all waste in appropriate receptacles. LESSEE shall be solely
responsible for any damage to plumbing equipment, sanitary lines, or any other
portion of the building which results from the discharge or use of any acid or
corrosive substance by LESSEE. LESSEE shall not permit the leased premises to be
overloaded, damaged, stripped or defaced, nor suffer any waste, and will not
keep animals within the leased premises. LESSEE will protect any carpet with
plastic or masonite chair pads under any rolling chairs. Unless heat is provided
at LESSOR's expense, LESSEE shall maintain sufficient heat to prevent freezing
of pipes or other damage. Any increase in air conditioning equipment or
electrical capacity, or any installation and/or maintenance of equipment which
is necessitated by some specific aspect of LESSEE's use of the leased premises
shall be at LESSEE's expense. All maintenance provided by LESSOR shall be during
LESSOR's normal business hours.

10. ALTERATIONS. LESSEE shall not make structural alterations or additions of
any kind to the leased premises, but may make nonstructural alterations provided
LESSOR consents thereto in writing. All such allowed alterations shall be at
LESSEE's expense and shall conform to LESSOR's construction specifications. If
LESSOR or LESSOR's agent provides any services or maintenance for LESSEE in
connection with such alterations or otherwise under this lease, any just invoice
of LESSOR or its contractors will be promptly paid by LESSEE. LESSEE shall not
permit any mechanics' liens, or similar liens, to remain upon the leased
premises in connection with work of any character performed or claimed to have
been performed at the direction of LESSEE and shall cause any such lien to be
released or removed forthwith without cost to LESSOR. Any alterations or
additions shall become part of the leased premises and the property of LESSOR.
Any alterations completed by LESSOR shall be LESSOR's "building standard" unless
noted otherwise. LESSOR shall have the right at any time to change the size,
area, level and location of parking areas, stairs, walkways, pathways,
entrances, driveways, landscaped areas or other common areas of the building.

11. ASSIGNMENT OR SUBLEASING. LESSEE shall not voluntarily, involuntarily or by
operation of law assign or encumber this lease or sublet or allow any other firm
or individual to occupy the whole or any part of the leased premises without
LESSOR's prior written consent such consent shall not be unreasonably withheld.
Notwithstanding such assignment or subleasing, LESSEE and GUARANTOR shall remain
liable to LESSOR for the payment of all rent and for the full performance of the
covenants and conditions of this lease. LESSEE shall pay LESSOR promptly for
legal and administrative expenses incurred by LESSOR in connection with any
consent requested hereunder by LESSEE. LESSEE shall be deemed to be in default
hereunder if the cumulative total of more than forty-nine percent (49%) of
LESSEE's stock, partnership interest or membership interest (as applicable)
shall be transferred in any manner during the term of this lease to other than
the present holders thereof or the spouse or lineal descendant of any present
holder who is a natural person. If LESSOR conveys or transfers its interest in
the building, upon such conveyance or transfer, LESSOR (and in the case of any
subsequent conveyances or transfers, the then grantor or transferor) shall be
entirely released from all liability with respect to the performance of any
obligation on the part of the landlord to be performed hereunder from and after
the date of such conveyance or transfer.

<PAGE>


12. SUBORDINATION. This lease shall be subject and subordinate to any and all
mortgages and other instruments in the nature of a mortgage, now or at any time
hereafter, and LESSEE shall, when requested, promptly execute and deliver such
written instruments as shall be requested to show the subordination of this
lease to said mortgages or other such instruments in the nature of a mortgage.
Notwithstanding the foregoing, if the mortgagee elects to have this lease
superior to such mortgage, then upon mortgagee's request LESSEE shall execute,
acknowledge and deliver an instrument, in form used by said mortgagee, effecting
such priority. In the event proceedings are brought for foreclosure of, or the
exercise of a power of sale under any such mortgage, LESSEE shall attorn to the
purchaser upon any such foreclosure or sale and recognize such purchaser as
landlord under this lease. LESSEE, upon request from LESSOR or any successor in
interest, shall execute, acknowledge and deliver such instruments as are
required to effect the intent of this section.

13. LESSOR'S ACCESS. LESSOR or agents of LESSOR may at any reasonable time enter
to view the leased premises, to make repairs and alterations as LESSOR should
elect to do for the leased premises, the common areas or any other portions of
the building, to make repairs which LESSEE is required but has failed to do, and
to show the leased premises to others.

14. SNOW REMOVAL. The plowing of snow from all roadways and unobstructed parking
areas shall be the sole responsibility of LESSOR, the expense of which shall be
included in Operating Costs. The control of snow and ice on all walkways, steps,
and loading areas serving the leased premises and all other areas not readily
accessible to plows unless they serve multiple tenants shall be the sole
responsibility of LESSEE. Notwithstanding the foregoing, however, LESSEE shall
hold LESSOR harmless from any and all claims by LESSEE's agents,
representatives, employees, callers or invitees for damage or personal injury
resulting in any way from snow or ice on any area serving the leased premises.

15. ACCESS AND PARKING. LESSEE shall have the right to use parking facilities
provided for the leased premises in common with others entitled to the use
thereof. Said parking area plus any stairs, walkways, elevators or other common
areas shall in all cases be considered a part of the leased premises when they
are used by LESSEE or LESSEE's employees, agents, callers or invitees. LESSEE
will not obstruct in any manner any portion of the building or the walkways or
approaches to the building, and will conform to all rules and regulations now or
hereafter made by LESSOR for parking, and for the care, use, or alteration of
the building, its facilities and approaches. LESSEE further warrants that LESSEE
will not permit any employee or visitor to violate this or any other covenant or
obligation of LESSEE. No unattended parking will be permitted between 7:00 PM
and 7:00 AM without LESSOR's prior written approval, and from December 1 through
March 31 annually, such parking shall be permitted only in those areas
specifically designated for assigned overnight parking. Unregistered or disabled
vehicles, or storage trailers of any type, may not be parked at any time. LESSOR
may tow, at LESSEE's sole risk and expense, any misparked vehicle belonging to
LESSEE or LESSEE's agents, employees, invitees or callers, at any time. LESSOR
shall not be responsible for providing any security services for the leased
premises.

16. LIABILITY. LESSEE shall be solely responsible as between LESSOR and LESSEE
for deaths or personal injuries to all persons whomsoever occurring in or on the
leased premises (including any common areas that are considered part of the
leased premises hereunder) from

<PAGE>


whatever cause arising, and damage to property to whomsoever belonging arising
out of the use, control, condition or occupation of the leased premises by
LESSEE; and LESSEE agrees to indemnify and save harmless LESSOR from any and all
liability, including but not limited to costs, expenses, damages, causes of
action, claims, judgments and attorney's fees of any kind which may be asserted
against or incurred by LESSOR as a result of any occurrence in or about the
leased premises or by reason of LESSEE's use or occupancy of the leased
premises, or by reason of a failure of LESSEE to perform any of its obligations
under this lease, or otherwise caused by or in any way growing out of any
matters aforesaid, except for death, personal injuries or property damage solely
and directly resulting from the gross negligence or willful misconduct of
LESSOR.

17. INSURANCE. LESSEE will secure and carry at its own expense worker's
compensation insurance at the minimum statutory amount, comprehensive general
public liability insurance under which LESSOR and LESSEE are named insureds,
against any claims based on bodily injury (including death) or property damage
arising out of the condition of the leased premises (including any common areas
that are considered part of the leased premises hereunder) or their use by
LESSEE, such policy to insure LESSEE, LESSOR and OWNER against any claim up to
Two Million Dollars (2,000,000) in the case of any one accident involving bodily
injury (including death), and up to Two Million Dollars ($2,000,000) against any
claim for damage to property and containing a contractual endorsement covering
LESSEE's indemnity obligation under this section. LESSOR and OWNER shall be
included in each such policy as additional insureds using ISO form CG 20 26 11
85 or some other form approved by LESSOR. LESSEE will file with LESSOR prior to
occupancy certificates and any applicable riders or endorsements showing that
such insurance is in force, and thereafter will file renewal certificates prior
to the expiration of any such policies. All such insurance certificates shall
provide that such policies shall not be cancelled without at least ten (10) days
prior written notice to each insured. In the event LESSEE shall fail to provide
or maintain such insurance at any time during the term of this lease, then
LESSOR may elect to contract for such insurance at LESSEE's expense. Anything in
this lease to the contrary notwithstanding, it is agreed that each party (the
"Releasing Party") hereby releases the other (the "Released Party") from any
liability from which the Released Party would, but for this section, have had to
the Releasing Party during the term of this lease, resulting from the occurrence
of any accident or occurrence or casualty (i) which is or would be covered by a
policy of physical hazard insurance of the type commonly referred to as an
"all-risk" policy affording coverage for the perils (u) of fire; (v) of
windstorm, (w) of flood, (x) of earthquake, (y) covered by broad form extended
coverage insurance as included in the standard form used in the Commonwealth of
Massachusetts, including, in particular without limitation, sprinkler leakage,
and (z) of explosion of steam pressure boilers and other similar apparatus
located in, on or about the building (irrespective of whether such coverage is
carried by the Releasing Party); or (ii) covered by any other casualty or
property damage insurance being carried by the Releasing Party at the time of
such occurrence, which accident, occurrence or casualty may have resulted in
whole or in part from any act or neglect of the Released Party, its officers,
agents or employees; provided, however, the release here and above set forth
shall become inoperative and null and void if the Releasing Party wishes to
place the appropriate insurance with an insurance company which (y) takes the
position that the existence of such release vitiates or would adversely affect
the policy so insuring the Releasing Party in a substantial manner and notice
thereof is given to the Released Party, or (z) requires the payment of a higher
premium by reason of the existence of such release, unless in the latter case
the

<PAGE>


Released Party within ten (10) days after notice thereof from the Releasing
Party pays such increase in premium.

18. SIGNS. LESSOR authorizes, and LESSEE at LESSEE's expense agrees to erect,
signage for the leased premises in accordance with all applicable governmental
regulations and with LESSOR's building standards for style, size, location, etc.
LESSEE shall obtain the prior written consent of LESSOR before erecting any sign
on the leased premises, which consent shall include approval as to size,
wording, design, and location. LESSOR may remove and dispose of any sign not
approved, erected or displayed in conformance with this lease.

19. BROKERAGE. LESSEE warrants and represents to LESSOR that LESSEE has dealt
with no broker or third person except Brad Spencer of Grubb & Ellis who will be
paid by LESSOR in accordance with LESSOR's standard fee schedule with respect to
this lease and LESSEE agrees to indemnify LESSOR against any brokerage claims
arising by virtue of this lease. LESSOR warrants and represents to LESSEE that
LESSOR has employed no exclusive broker or agent in connection with the letting
of the leased premises.

20. DEFAULT AND ACCELERATION OF RENT. In the event that: (a) any assignment for
the benefit of creditors, trust mortgage, receivership or other insolvency
proceeding shall be made or instituted with respect to LESSEE or LESSEE's
property; (b) LESSEE shall default in the observance or performance of any of
LESSEE's covenants, agreements, or obligations hereunder, other than substantial
monetary payments as provided below, and such default shall not be corrected
within ten (10) days after written notice thereof; or (c) LESSEE vacates the
leased premises for twenty (20) consecutive days, then LESSOR shall have the
right thereafter, while such default continues and without demand or further
notice, at LESSOR's option, either (i) to terminate this lease, or (ii) without
terminating this lease, to take possession of the leased premises, with or
without process of law, using such force as may be necessary to remove all
persons and personal property therefrom, and in the event of such re-entry
without termination, LESSOR may (but shall have no obligation to do so) lease
the leased premises for the remainder of the term or for a lesser longer period
on such terms and conditions as LESSOR, in its sole judgment, deems advisable
and for the purpose of such re-letting, LESSOR is hereby authorized to make such
repairs and alterations as LESSOR deems necessary. Notwithstanding any
re-letting without termination, (y) LESSEE shall remain liable for payment of
the base rent, Additional Rent and all other charges and for the performance of
all other obligations to be performed by LESSEE under this lease, and (z) LESSOR
may at any time thereafter elect to terminate this lease for such previous
breach. The rentals received from such re-letting shall first be applied to the
expenses of such re-letting (including alteration and repair expenses and
reasonable brokerage and attorneys' fees); and second to the payment of rent and
other charges due and paid hereunder. LESSEE shall not be entitled to receive
any surplus funds received by LESSOR from such re-letting. If such funds from
the re-letting are less than those required to be paid by LESSEE or under for
any month, such deficiency shall be calculated and payable monthly by LESSEE.
LESSOR shall also be entitled to collect from LESSEE any other loss or damage
which LESSOR may sustain by reason of LESSEE's default under this lease. In
addition to the foregoing, LESSOR shall have all other rights and remedies
available to it at law or in equity. If LESSEE shall default in the payment of
the security deposit, rent, taxes, substantial invoice from LESSOR or LESSOR's
agent for goods and/or services or other sum herein specified, and such default
shall continue for ten (10) days after written notice thereof, and,

<PAGE>


because both parties agree that nonpayment of said sums when due is a
substantial breach of the lease, and, because the payment of rent in monthly
installments is for the sole benefit and convenience of LESSEE, then in addition
to the foregoing remedies the entire balance of rent which is due hereunder
shall become immediately due and payable as liquidated damages. LESSOR, without
being under any obligation to do so and without thereby waiving any default, may
remedy any such default of LESSEE for the account and at the expense of LESSEE.
If LESSOR pays or incurs any obligations for the payment of money in connection
therewith, such sums paid or obligations incurred plus interest and costs, shall
be paid to LESSOR by LESSEE as additional rent. Any sums received by LESSOR from
or on behalf of LESSEE at any time shall be applied first to any unamortized
improvements completed for LESSEE's occupancy, then to offset any outstanding
invoice or other payment due to LESSOR, with the balance applied to outstanding
rent. LESSEE agrees to pay reasonable attorney's fees and/or administrative
costs incurred by LESSOR in enforcing any or all obligations of LESSEE under
this lease at any time. LESSEE shall pay LESSOR interest at the rate of eighteen
percent (18%) per annum on any payment from LESSEE to LESSOR which is past due.
If LESSEE fails to perform any obligations on its part to be performed under
this lease, LESSOR shall have the right (i) if no emergency exists, to perform
the same after giving ten (10) days notice to LESSEE; and (ii) in any emergency
situation perform the same immediately without notice or delay. LESSEE shall on
demand reimburse LESSOR for costs incurred by LESSOR in rectifying LESSEE's
defaults as aforesaid, including reasonable attorneys' fees. Except for the
gross negligence or willful misconduct by LESSOR, LESSOR shall not be liable or
in any way responsible for any loss, inconvenience or damage resulting to LESSEE
for any action taken by LESSOR pursuant to this section.

21. NOTICE. Any notice from LESSOR to LESSEE relating to the leased premises or
to the occupancy thereof shall be deemed duly served when left at the leased
premises addressed to LESSEE, or served by constable, or sent to the leased
premises by certified mail, return receipt requested, postage prepaid, addressed
to LESSEE, or by nationally recognized overnight delivery. Any notice from
LESSEE to LESSOR relating to the leased premises or to the occupancy thereof
shall be deemed duly served when served by constable, or delivered to LESSOR by
certified mail, return receipt requested, postage prepaid, or by nationally
recognized overnight delivery addressed to LESSOR c/o Pinnacle Properties
Management, Inc. at 56 Roland Street, Boston, MA 02129 or at LESSOR's last
designated address with a copy to Frank P. Brady, Esq., Polsinelli, White,
Vardeman & Shalton, 7500 College Boulevard, Suite 750, Overland Park, KS 66210.
No oral notice or representation shall have any force or effect. Time is of the
essence in service of any notice.

22. OCCUPANCY. In the event that LESSEE takes possession of said leased premises
prior to the start of said term, LESSEE will perform and observe all of LESSEE's
covenants from the date upon which LESSEE takes possession except the obligation
for the payment of extra rent for any period of less than one month. LESSEE
shall not remove LESSEE's goods or property from the leased premises other than
in the ordinary and usual course of business, without having first paid and
satisfied LESSOR for all rent which may become due during the entire term of
this lease. LESSOR shall have the right to relocate LESSEE to another facility
upon prior written notice to LESSEE and on terms comparable to those herein. If
LESSOR relocates LESSEE, LESSOR shall reimburse LESSEE for LESSEE's reasonable
out-of-pocket expenses for moving LESSEE's furniture, equipment, and supplies
from the leased premises to the relocation space

<PAGE>


and for reprinting LESSEE's stationery of the same quality and quantity as
LESSEE's stationery supply on hand immediately before LESSOR's notice to LESSEE
of the exercise of this relocation right. Upon such relocation, the relocation
space shall be deemed to be the leased premises and the terms of the lease shall
remain in full force and shall apply to the relocation space. In the event that
LESSEE continues to occupy or control all or any part of the leased premises
after the agreed termination of this lease without the written permission of
LESSOR, then LESSEE shall be liable to LESSOR for any and all loss, damages or
expenses incurred by LESSOR, and all other terms of this lease shall continue to
apply except that rent shall be due in full monthly installments at a rate of
one hundred fifty percent (150%) of that which would otherwise be due under this
lease, it being understood between the parties that such extended occupancy is
as a tenant at sufferance and is solely for the benefit and convenience of
LESSEE and as such has greater rental value. LESSEE's control or occupancy of
all or any part of the leased premises beyond noon on the last day of any
monthly rental period shall constitute LESSEE's occupancy for an entire
additional month, and increased rent as provided in this section shall be due
and payable immediately in advance. LESSOR's acceptance of any payments from
LESSEE during such extended occupancy shall not alter LESSEE's status as a
tenant at sufferance.

23. FIRE PREVENTION. LESSEE agrees to use every reasonable precaution against
fire and agrees to provide and maintain approved, labeled fire extinguishers,
emergency lighting equipment, and exit signs and complete any other
modifications within the leased premises as required or recommended by the
Insurance Services Office (or successor organization), OSHA, the local Fire
Department, or any similar body.

24. OUTSIDE AREA. No goods, equipment, or things of any type or description
shall be held or stored outside the leased premises at any time without prior
written consent from LESSOR. Any goods, equipment or things left outside the
leased premises without LESSOR's prior written consent shall be deemed abandoned
and may be removed at LESSEE's expense without notice by LESSOR. LESSEE shall
have a building standard size dumpster in a location approved by LESSOR,
provided and serviced at LESSEE's expense by whichever disposal firm may from
time to time be designated by LESSOR, unless a shared dumpster or compactor is
provided by LESSOR, in which case LESSEE shall pay its proportionate share of
any costs associated therewith.

25. ENVIRONMENT. LESSEE will so conduct and operate the leased premises as not
to interfere in any way with the use and enjoyment of other portions of the same
or neighboring buildings by others by reason of odors, smoke, smells, noise,
pets, accumulation of garbage or trash, vermin or other pests, or otherwise, and
will at its expense employ a professional pest control service if necessary.
LESSEE agrees to maintain efficient and effective devices for preventing damage
to heating equipment from solvents, degreasers, cutting oils, propellants, etc.
which may be present at the leased premises. No hazardous materials or wastes
shall be stored, disposed of, or allowed to remain at the leased premises at any
time, and LESSEE shall be solely responsible for any and all corrosion or other
damage associated with the use, storage and/or disposal of same by LESSEE.
LESSEE agrees not to unreasonably or unlawfully introduce any hazard or toxic
materials onto the leased premises without (a) first obtaining LESSOR's written
consent, and (b) complying with all applicable Federal, state and local laws or
ordinances pertaining to the transportation, storage, use or disposal of such
materials, including but not

<PAGE>


limited to, obtaining proper permits. If LESSEE's transportation, storage, use
or disposal of hazardous or toxic materials on the leased premises results in
(i) contamination of the soil or surface or ground water or (ii) loss or damage
to persons or property, then LESSEE agrees (1) to notify LESSOR immediately of
any contamination, claim of contamination, loss or damage, (2) after
consultation and approval by LESSOR, to clean-up, at LESSEE's sole expense,
contamination in full compliance with all applicable statutes, regulations and
standards, and (3) to indemnify, defend and hold LESSOR harmless from and
against any claims, suits, causes of action, costs and fees, including
reasonable attorneys' fees arising from or connected with any such
contamination, claim of contamination, loss, damage or clean-up. This provision
shall survive termination of this lease.

26. RESPONSIBILITY. LESSOR shall not be held liable to anyone for loss or damage
caused in any way by the use, leakage, seepage or escape of water from any
source, or for the cessation of any service rendered customarily to said leased
premises or buildings, or agreed to by the terms of this lease, due to any
accident, the making of repairs, alterations or improvements, labor
difficulties, weather conditions, mechanical breakdowns, trouble or scarcity in
obtaining fuel, electricity, service or supplies from the sources from which
they are usually obtained for said building, or any cause beyond LESSOR's
immediate control.

27. SURRENDER. LESSEE shall at the termination of this lease remove all of
LESSEE's goods and effects from the leased premises. LESSEE shall deliver to
LESSOR the leased premises and all keys and locks thereto, all fixtures and
equipment connected therewith, and all alterations, additions and improvements
made to or upon the leased premises, whether completed by LESSEE, LESSOR, or
others, including but not limited to any offices, partitions (except movable
partitions supplied and installed by LESSEE), window blinds, floor coverings
(including computer floors), plumbing and plumbing fixtures, air conditioning
equipment and ductwork of any type, exhaust fans or heaters, water coolers,
burglar alarms, telephone wiring, telephone equipment, air or gas distribution
piping, compressors, overhead cranes, hoists, trolleys or conveyors, counters,
shelving or signs attached to walls or floors, all electrical work, including
but not limited to lighting fixtures of any type, wiring, conduit, EMT,
transformers, distribution panels, bus ducts, raceways, outlets and disconnects,
and furnishings (except kitchen-type appliances supplied and installed by
LESSEE) or equipment which have been bolted, welded, nailed, screwed, glued or
otherwise attached to any wall, floor or ceiling, or which have been directly
wired to any portion of the electrical system or which have been plumbed to the
water supply, drainage or venting systems serving the leased premises. LESSEE
shall deliver the leased premises sanitized from any chemicals or other
contaminants, and broom clean and in the same condition as they were at the
commencement of this lease or any prior lease between the parties for the leased
premises, or as they were modified during said term with LESSOR's written
consent, reasonable wear and tear and damage by fire or other casualty only
excepted. In the event of LESSEE's failure to remove any of LESSEE's property
from the leased premises upon termination of the lease, LESSOR is hereby
authorized, without liability to LESSEE for loss or damage thereto, and at the
sole risk of LESSEE, to remove and store any such property at LESSEE's expense,
or to retain same under LESSOR's control, or to sell at public or private sale
(without notice), any or all of the property not so removed and to apply the net
proceeds of such sale to the payment of any sum due hereunder, or to destroy
such abandoned property. In no case shall the leased premises be deemed
surrendered to LESSOR

<PAGE>


until the termination date provided herein or such other date as may be
specified in a written agreement between the parties, notwithstanding the
delivery of any keys to LESSOR.

28. GENERAL. (a) The invalidity or unenforceability of any provision of this
lease shall not affect or render invalid or unenforceable any other provision
hereof. (b) The obligations of this lease shall run with the land, and this
lease shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns, except that LESSOR shall be liable only
for obligations occurring while lessor, owner, or master lessee of the leased
premises. (c) Any action or proceeding arising out of the subject matter of this
lease shall be brought by LESSEE within one year after the cause of action has
occurred and only in a court of the Commonwealth of Massachusetts. (d) If LESSOR
is acting under or as agent for any trust or corporation, the obligations of
LESSOR shall be binding upon the trust or corporation, but not upon any trustee,
officer, director, shareholder, or beneficiary of the trust or corporation
individually. (f) This lease is made and delivered in the Commonwealth of
Massachusetts, and shall be interpreted, construed, and enforced in accordance
with the laws thereof. (g) This lease was the result of negotiations between
parties of equal bargaining strength, and when executed by both parties shall
constitute the entire agreement between said parties. No other oral or written
representation shall have any effect hereon, and this agreement may not be
altered, extended or amended except by written agreement attached hereto or as
otherwise provided herein. (h) Notwithstanding any other statements herein,
LESSOR makes no warranty, express or implied, concerning the suitability of the
leased premises for LESSEE's intended use. (i) LESSEE agrees that if LESSOR does
not deliver possession of the leased premises as herein provided for any reason,
LESSOR shall not be liable for any damages to LESSEE for such failure, but
LESSOR agrees to use reasonable efforts to deliver possession to LESSEE at the
earliest possible date, and a proportionate abatement of rent for such time as
LESSEE may be deprived of possession of said leased premises shall be LESSEE's
sole remedy. (j) Neither the submission of this lease form, nor the prospective
acceptance of the security deposit and/or rent shall constitute a reservation of
or option for the leased premises, or an offer to lease, it being expressly
understood and agreed that this lease shall not bind either party in any manner
whatsoever until it has been executed by both parties. (k) LESSEE shall not be
entitled to exercise any option contained herein if LESSEE is in default of any
terms or conditions hereof. (1) The headings in this lease are for convenience
only and shall not be considered part of the terms hereof. (m) No endorsement by
LESSEE on any check shall bind LESSOR in any way.

29. SECURITY AGREEMENT. LESSEE hereby grants LESSOR a continuing security
interest in all existing or hereafter acquired property of LESSEE which is in
the leased premises to secure the payment of rent, the cost of leasehold
improvements, and the performance of any other obligations of LESSEE under this
lease. Default in the payment or performance of any of LESSEE's obligations
hereunder is a default under this security agreement, and shall entitle LESSOR
to immediately exercise all of the rights and remedies of a secured party under
the Uniform Commercial Code. LESSEE also agrees to execute a UCC-1 Financing
Statement and any other financing agreement required by LESSOR in connection
with this security interest.

30. WAIVERS, ETC. No consent or waiver, express or implied, by LESSOR, to or of
any breach of any covenant, condition or duty of LESSEE shall be construed as a
consent or waiver to or of any other breach of the same or any other covenant,
condition or duty. If LESSEE is several persons, several corporations or a
partnership, LESSEE's obligations are joint or

<PAGE>


partnership and also several. Unless repugnant to the context, "LESSOR" and
"LESSEE" mean the person or persons, natural or corporate, named above as LESSOR
and as LESSEE respectively, and their respective heirs, executors,
administrators, successors and assigns.

31. AUTOMATIC FIVE YEAR EXTENSIONS. This lease, including all terms, conditions,
escalations, etc. shall be automatically extended for additional successive
periods of five (5) years each unless LESSOR or LESSEE shall serve written
notice, either party to the other, of either party's desire not to so extend the
lease. The time for serving such written notice shall be not more than twelve
(12) months or less than six (6) months prior to the expiration of the then
current lease period. Time is of the essence.

32. JURY TRIAL. LESSOR and LESSEE hereby waive any and all rights to a jury
trial in any summary process or eviction proceeding in any way arising out of
the lease.

33. ESTOPPEL CERTIFICATES. From time to time, LESSEE shall furnish to any party
designated by LESSOR, within ten (10) days after a request therefor, a
certificate signed by LESSEE confirming and containing such factual
certifications and representations as to this lease as LESSOR may reasonably
request.

34. CORPORATE APPROVAL. Concurrently with its execution of the lease, LESSEE
shall provide LESSOR with duly authorized and executed corporate resolutions (in
form and substance satisfactory to LESSOR) authorizing the entering into and
consummation of the transactions contemplated by this lease and designating the
corporate or other officer or officers to execute this lease on behalf of
LESSEE.

35. FINANCIAL REPORTS. Within fifteen (15) days after LESSOR's request, LESSEE
shall furnish LESSEE's most recent audited financial statements (including any
notes to them) to LESSOR, or, if no such audited statements have been prepared,
such other financial statements (and notes to them) as may have been prepared by
an independent certified public accountant or, failing those, LESSEE's
internally prepared financial statements. LESSEE will discuss its financial
statements with LESSOR and will give LESSOR access to LESSEE's books and records
in order to enable LESSOR to verify the financial statements. LESSOR will not
disclose any aspect of LESSEE's financial statements that LESSEE designates to
LESSOR as confidential except (i) to LESSOR's lenders or prospective purchasers
of the property, (ii) in litigation between LESSOR and LESSEE, and (iii) if
required by court order.

36. CONFIDENTIALITY. LESSEE acknowledges that the terms and conditions of this
lease are to remain confidential for the LESSOR's benefit, and may not be
disclosed by LESSEE to anyone, by any manner or means, directly or indirectly,
without LESSOR's prior written consent.

37. LEGAL EXPENSE; REMEDIES CUMULATIVE. In case suit should be brought because
of the breach by LESSEE of any of its obligations under this lease, LESSOR shall
be entitled to recover all expenses incurred in connection with such breach,
including reasonable attorneys' fees. LESSOR's rights and remedies shall be
cumulative and may be exercised and enforced concurrently, and no right or
remedy of LESSOR shall be deemed to be exclusive of any other right or remedy it
may have.

<PAGE>


38. LIMITATION ON LESSOR'S LIABILITY. Notwithstanding anything set forth in this
lease to the contrary, it is agreed that LESSEE shall look solely to the equity
of LESSOR in the building for the satisfaction of the remedies of LESSEE in the
event of a breach by LESSOR of any of the provisions of this lease, and LESSOR
shall not be liable for any such breach except to the extent of LESSOR's equity
in the building.

39. ADDITIONAL PROVISIONS. (Continued on attached rider if necessary.)

LESSOR at no additional cost to LESSEE, shall perform the following work at the
leased premises:
Remove the existing tile in the rear portion of the leased premises;
Replace the existing carpet in the existing office area and perimeter
offices with new carpet and vinyl cove base; and
Perform punchlist items including: installing covers over existing electrical
outlets, replacing damaged ceiling tiles, and painting the back double metal
doors.

LESSOR, at LESSOR's option, may construct up to an additional 10,000 square feet
onto the existing building as shown on Exhibit "B" attached hereto ("Potential
Addition") that may temporarily or permanently affect LESSEE's access to and
from its tenant entry door and may involve relocating LESSEE's tenant entry
door. In the event that the LESSOR makes the Potential Addition, LESSEE's
proportionate share of Operating Costs and Taxes shall be equitably adjusted to
reflect the new square footage of the building. In such event, LESSOR shall
diligently pursue the completion of the Potential Addition and shall use
reasonable efforts to complete the Potential Addition without undue delay and in
a manner which does not materially and unreasonably affect LESSEE's use,
enjoyment and occupation of the leased premises.

IN WITNESS WHEREOF, LESSOR AND LESSEE have hereunto set their hands and common
seals and intend to be legally bound hereby this 13th day of May

ADDENDUM

         This Addendum shall constitute an integral part of the Lease ("Lease")
of even date herewith between 6-8 Preston Court, L.L.C. ("Lessor") and Asiana
Pharmaceuticals Corporation ("Lessee") with respect to the Premises commonly
known as 8A Preston Court. To the extent any of the terms and conditions set
forth in this Addendum are inconsistent with the terms and conditions set forth
in the Lease, the terms and conditions of this Addendum shall supercede the
terms and conditions of the Lease and the terms and conditions of this Addendum
shall govern.

         The parties agree as follows:

         1. Lessee shall immediately provide Lessor with telephonic notice,
which shall promptly be confirmed by written notice, of any and all spillage,
discharge, release and disposal of Hazardous Material onto or within the
Premises, including the soils and subsurface waters thereof, which by law must
be reported to any federal, state or local agency, and any injuries or damages
resulting directly or indirectly therefrom. Further, Lessee shall deliver to
Lessor each and every notice or order, when said order or notice identifies a
violation which may have the potential to adversely impact the Premises,
received from any federal, state or local agency concerning Hazardous Material
and the possession, use and/or accumulation thereof promptly upon receipt of
each such notice or order by Lessee. Lessor shall have the right, upon
reasonable notice, to inspect and copy each and every notice or order received
from any federal, state or local agency concerning Hazardous Material and the
possession, use and/or accumulation thereof.

         2. Lessee shall be responsible for and shall indemnify, protect, defend
and hold harmless Lessor and Lessor's Agents (defined as Lessor's members,
employees, agents, contractors, licensees or invitees) from any and all
liability, damages, injuries, causes of action, claims, judgments, costs,
penalties, fines, losses, and expenses which arise during or after the term of
this Lease and which result from Lessee's or from Lessee's Agents (defined as
Lessee's assignees, sublessees, employees, agents, contractors, licensees, or
invitees) receiving, handling, use, storage, accumulation, transportation,
generation, spillage, migration, discharge, release or disposal of Hazardous
Material in, upon or about the Premises, including without limitation (i)
diminution in value of the Premises, (ii) damages for the loss or restriction on
use of any portion or amenity of the Premises, (iii) damages arising from any
adverse impact on marketing of space in the Building, (iv) damages and the costs
of remedial work to other property in the vicinity of the Premises owned by
Lessor or an affiliate of Lessor, and (v) consultant fees, expert fees, and
attorneys' fees.

         3. The indemnification pursuant to the preceding Section 2 includes,
without limiting the generality of Section 2, reasonable costs incurred in
connection with any investigation of site conditions, cleanup, remedial, removal
or restoration work required by any federal, state or local governmental agency
or political subdivision because of Hazardous Material present in the soil,
subsoil, ground water, or elsewhere on, under or about the Premises, or on,
under or about any other property in the vicinity of the Premises owned by
Lessor or an affiliate of Lessor. Without limiting the foregoing, if the
presence of any Hazardous Material on the Premises caused or permitted by Lessee
results in any contamination of the Premises, or underlying soil or groundwater,
Lessee shall promptly take all actions at its sole expense as are

<PAGE>


necessary to return the Premises to the condition existing prior to the
introduction of any such Hazardous Material, provided that Lessor's approval of
such action shall first be obtained, which approval shall not be unreasonably
withheld so long as such actions would not potentially have any material adverse
long-term or short-term effect on the Premises, except that Lessee shall not be
required to obtain Lessor's prior approval of any action of an emergency nature
reasonably required or any action mandated by a governmental authority, but
Lessee shall give Lessor prompt notice thereof.

         4. Notwithstanding other provisions of this Addendum, it shall be a
default under this Lease, and Lessor shall have the right to terminate the Lease
and/or pursue its other remedies under the Lease, in the event that (i) Lessee's
use of the Premises for the generation, storage, use, treatment or disposal of
Hazardous Material is in a manner or for a purpose prohibited by applicable law
unless Lessee is diligently pursuing compliance with such law, (ii) Lessee has
been required by any governmental authority to take remedial action in
connection with Hazardous Material contaminating the Premises if the
contamination resulted from Lessee's action or use of the Premises, unless
Lessee is diligently pursuing compliance with such requirement, or (iii) Lessee
is subject to an enforcement order issued by any governmental authority in
connection with the use, disposal or storage of a Hazardous Material on the
Premises, unless Lessee is diligently seeking compliance with such enforcement
order.

         5. At any time prior to the expiration or earlier termination of the
term of the Lease, Lessor shall have the right to enter upon the Premises at all
reasonable times and at reasonable intervals in order to conduct appropriate
tests regarding the presence, use and storage of Hazardous Material, and to
inspect Lessee's records with regard thereto. Lessee will pay the reasonable
costs of any such test which demonstrates that contamination in excess of
permissible levels has occurred and such contamination was caused by use of the
Premises during the term of the Lease. Lessee shall correct any deficiencies
identified in any such tests in accordance with its obligations under this
Addendum.

         6. Lessee shall at its own expense cause an environmental site
assessment of the Premises to be conducted and a report thereof delivered to
Lessor upon the expiration or earlier termination of the Lease. This report
shall consist of a visual inspection of the premises for visible signs of
possible contamination and an inspection of records regarding the generation,
storage, use, disposal, and transport of Hazardous Materials within the Premises
during Lessee's occupancy (hereinafter referred to as the "Exit Report"), or a
more complete and broader report only if so recommended in the Exit Report to
investigate areas of possible contamination. Lessee shall correct any
deficiencies identified in such report in accordance with its obligations under
this Addendum prior to the expiration or earlier termination of this Lease.

         7. Lessee's obligations under this Addendum shall survive the
termination of the Lease. Should Lessee employ any period of time after the
expiration or earlier termination of this Lease, to complete the removal from
the Premises of any such Hazardous Material, Lessee shall be a Lessee at
sufferance subject to the provisions of Section 22 of the Lease.

         8. As used herein, the term "Hazardous Material" means any hazardous or
toxic substance, material or:waste which is or becomes regulated by any local
governmental authority, the State of Massachusetts or the United States
Government.

<PAGE>


         9. If Lessee shall request Lessor's consent to any assignment of this
Lease or to any subletting of all or any part of the Premises, Lessee shall
submit to Lessor with such request the name of the proposed assignee or
subLessee, such information concerning its business, financial responsibility
and standing as Lessor may reasonably require, and the consideration and rents
(and terms and conditions thereof) to be paid for and the effective date of the
proposed assignment or subletting. Upon receipt of such request and all such
information, Lessor shall have the right (without limiting Lessor's right of
consent in respect of such assignment or subletting), by giving notice to Lessee
within fifteen ;(15) days thereafter, (oseq level3 \*romanoio) to terminate this
Lease if the request is for an assignment or a subletting of all the Premises,
or (oseq level3 \*romanoiio) if such request is to sublet a portion of the
Premises only, to terminate this Lease with respect to such portion. If Lessor
exercises its right to terminate this Lease, the effective date of termination
shall be set forth in Lessor's notice to Lessee, but such date shall not be
earlier than the effective date of the proposed assignment or subletting nor
later than ninety (90) days thereafter. If Lessor so elects to terminate this
Lease, Lessee shall continue to pay the Rent and other charges hereunder to
Lessor until the effective date of termination, on which date Lessee will
surrender possession of the Premises, or the portion thereof subject to such
right of termination, to Lessor in accordance with the provisions hereof. If
Lessor shall terminate this Lease as to a portion of the Premises only, then
following such termination the Rent and Additional Rent shall be reduced in the
same proportion as the number of square feet of net rentable footage in such
portion of the Premises bears to the number of square feet of net rentable
footage in the Premises immediately prior to such termination.

         10. oseq level2 \h \rO ooseq level3 \h \r0 o If Lessee shall request
Lessor consent to an assignment of this Lease and Lessor shall consent thereto,
the assignee ("Assignee") shall pay directly to Lessor, as additional rent
hereunder, at such times as Assignee shall have agreed to pay Lessee, an amount
equal to any consideration Assignee shall have agreed to pay Lessee on account
of such assignment. If Assignee shall fail to pay Lessor any such consideration
when due, such failure shall constitute a default under this Lease.

         11. If Lessee shall request Lessor's consent to a subletting of the
Premises or any part thereof and Lessor shall consent thereto, Lessee shall pay
Lessor as Additional Rent, in addition to the Rent and other charges payable
hereunder, an amount equal to any consideration paid by the subtenant to Lessee
in excess of (oseq level3 \*romanoio) the Rent and other charges payable
hereunder if all of the Premises are so sublet, or (*seq level3 \*romanoiio) if
less than all, of the Premises are so sublet, the Rent and other charges payable
hereunder allocable to the portion of the Premises so sublet based on the number
of square feet of net useable footage the Premises so sublet to the total number
of square feet of net useable footage in the Premises. The foregoing amount
shall be determined monthly and paid by Lessee to Lessor on the first day of
each calendar month in advance during the term of such sublease. If Lessee shall
fail to pay Lessor any such consideration, such failure shall be a default under
this Lease.

of May, 1999.

CORPORATION, LESSEE, HEREBY AGREE TO AMEND SAID LEASE AS FOLLOWS:

1. Provided LESSOR is able to obtain a building permit and all other permits and

                              AMENDMENT TO LEASE #3

IN CONNECTION WITH A LEASE CURRENTLY IN EFFECT BETWEEN THE PARTIES AT 8-A
PRESTON COURT, BEDFORD, MASSACHUSETTS, EXECUTED ON MAY 13, 1999 AND TERMINATING
MAY 30, 2004 ("LEASE"), AND IN CONSIDERATION OF THE MUTUAL BENEFITS TO BE
DERIVED HEREFROM, 6-8 PRESTON COURT, L.L.C., LESSOR AND ASIANA PHARMACEUTICALS
CORPORATION, LESSEE, HEREBY AGREE TO AMEND SAID LEASE AS FOLLOWS:

1. The leased premises shall be referred to as 6-A Preston Court rather than 8-A
Preston Court.

2. Per Section 31 of the Lease, the current lease term is hereby extended for an
additional five year term ("Extended Term") and shall now terminate on May 30,
2009 instead of on May 30, 2004. The base rent shall be in accordance with the
existing Lease and amendments including all escalations.

3. LESSEE shall accept the leased premises in "AS IS" "WHERE IS" condition,
without warranty or representation.

4. Notwithstanding anything in the Lease to the contrary, LESSEE may assign the
Lease or sublease all or part of the leased premises (a "PERMITTED TRANSFER") to
the following types of entities (a "PERMITTED TRANSFEREE") with written notice
to LESSOR but without the written consent of LESSOR: (1) an Affiliate (as
hereinafter defined) of LESSEE; (2) any corporation, limited partnership,
limited liability partnership, limited liability company or other business
entity in which or with which LESSEE, or its corporate successors or assigns, is
merged or consolidated, in accordance with applicable statutory provisions
governing merger and consolidation of business entities, so long as (A) LESSEE's
obligations hereunder are assumed by the entity surviving such merger or created
by such consolidation; and (B) the Tangible Net Worth (as hereinafter defined)
of the surviving or created entity is not less than the Tangible Net Worth of
LESSEE as of the date hereof; or (3) any corporation, limited partnership,
limited liability partnership, limited liability company or other business
entity acquiring all or substantially all of LESSEE's assets if such entity's
Tangible Net Worth after such acquisition is not less than the Tangible Net
Worth of LESSEE as of the date hereof. LESSEE shall promptly notify LESSOR of
any such Permitted Transfer. LESSEE shall remain liable for the performance of
all of the obligations of LESSEE hereunder, or if LESSEE no longer exists
because of a merger, consolidation, or acquisition, the surviving or acquiring
entity shall expressly assume in writing the obligations of LESSEE hereunder.
Additionally, the Permitted Transferee shall comply with all of the terms and
conditions of this Lease. No later than 30 days after the effective date of any
Permitted Transfer, LESSEE agrees to furnish LESSOR with (A) copies of the
instrument effecting the Permitted Transfer, (B) documentation establishing
LESSEE's satisfaction of the requirements set forth above applicable to any such
Permitted Transfer, and (C) evidence of insurance as required under the Lease
with respect to the Permitted Transferee. "TANGIBLE NET WORTH" means the excess
of total assets over total liabilities, in each case as

determined in accordance with generally accepted accounting principles
consistently applied ("GAAP"), excluding, however, from the determination of
total assets all assets which would be classified as intangible assets under
GAAP including goodwill, licenses, patents, trademarks, trade names, copyrights,
and franchises. "Affiliate" means any person or entity which, directly or
indirectly, through one or more intermediaries, controls, is controlled by, or
is under common control with the party in question.

5. LESSEE represents that Munchi BioTherapeutics Corp. (a Delaware corporation)
has succeeded to the interests of Asiana Pharmaceuticals Corporation (a
Massachusetts corporation) as LESSEE of the leased premises, and Munchi
BioTherapeutics Corp. hereby assumes all obligations and liabilities of the
LESSEE under the Lease.

6. LESSOR agrees to maintain casualty insurance in a commercially reasonable
amount for the building of which the leased premises are a part.

7. LESSEE'S agreement to subordinate this Lease to any and all future mortgages
and/or other future instruments in the nature of a mortgage, is conditional upon
LESSOR using reasonable efforts and due diligence to obtain the future
mortgagee's agreement that LESSEE's possession will not thereafter be disturbed
so long as LESSEE is not in default in the payment of rent or other covenants or
obligations hereof.

8. In Section 21 of the Lease, the notice address for Frank Brady is changed to
the following: Frank Brady, Esq., Pinnacle Properties Management,. LLC, 10955
Lowell Avenue, Suite 600, Overland Park, KS 66210. Additionally, the following
is added at the end of the first sentence: "with a copy to Bryan Keaney, Synta
Pharmaceuticals, Inc., 45 Hartwell Avenue, Lexington, MA 02421".

9. The first, third, fourth and fifth sentences of Section 22 of the Lease are
hereby deleted.

10. In Section 25 of the Lease, the phrase "no hazardous materials or waste
shall be stored, disposed of, or allowed to remain at the leased premises at any
time, and" is hereby replaced with "no hazardous materials or waste shall be
stored, disposed of, or allowed to remain at the leased premises at any time
except in compliance with all applicable statutes, regulations, ordinances and
the like, and".

11. Per Section 35 of the Lease, provided LESSEE is not in default of the Lease,
LESSEE will not be required to provide financial statements more than one time
per year if requested by LESSOR.

12. Section 36 of the Lease is hereby deleted in its entirety.

13. Section 37 of the Lease shall be amended by the addition of the following
language to the end of that section: "The prevailing party may recover from the
non prevailing party reasonable attorney's fees."

or third person with respect to this lease amendment and LESSEE agrees to
indemnify LESSOR against any brokerage claims arising by any person or entity
claiming by, through or under LESSEE.
