                                    AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    1.   Purpose of the Plan.

         The purpose of the AyurCore, Inc. 1997 Stock Option Plan (the 
"Plan") is to advance the interests of AyurCore, Inc., a Delaware corporation 
(the "Company"), by providing an opportunity for ownership of the stock of 
the Company by employees, agents and directors of, and consultants to, the 
Company or of any subsidiary corporation (herein called "subsidiary" or 
"subsidiaries"), as defined in Section 424(f) of the Internal Revenue Code of 
1986, as amended (the "Code") and the Treasury regulations promulgated 
thereunder (the "Regulations").  Such employees, agents and directors of, and 
consultants to, the Company or any subsidiary are hereinafter referred to 
individually as an "Eligible Person" and collectively as "Eligible Persons".  
By providing an opportunity for such stock ownership, the Company seeks to 
attract and retain qualified personnel, and otherwise to provide additional 
incentive for optionees to promote the success of its business.

    2.   Stock Subject to the Plan.

         (a)  The total number of shares of the authorized but unissued or 
treasury shares of the common stock, having no par value per share, of the 
Company (the "Common Stock") for which options may be granted under the Plan 
(the "Options") shall be 227,986, subject to adjustment as provided in 
Section 13 hereof.

         (b)  If an Option granted or assumed hereunder shall expire or 
terminate for any reason without having been exercised in full, the 
unpurchased shares subject thereto shall again be available for subsequent 
Option grants under the Plan.

         (c)  Common Stock issuable upon exercise of an Option may be subject 
to such restrictions on transfer, repurchase rights or other conditions or 
restrictions as shall be determined by the Board of Directors of the Company 
(the "Board").

    3.   Administration of the Plan.

         (a)  The Plan shall be administered by the Board.  No member of the 
Board shall act upon any matter affecting any Option granted or to be granted 
to himself or herself under the Plan; provided, however, that nothing 
contained herein shall be deemed to prohibit a member of the Board from 
acting upon any matter generally affecting the Plan or any Options granted 
thereunder.  A majority of the members of the Board shall constitute a 
quorum, and any action may be taken by a majority of those present and voting 
at any meeting.  The decision of the Board as to all questions of 
interpretation and application of the Plan shall be final, binding and 
conclusive on all persons.  The Board, in its sole discretion, may grant 
Options to purchase shares of the Common Stock only as provided in the Plan, 
and shares shall be issued upon exercise of such Options as provided in the 
Plan.  The Board shall have authority, subject to the express provisions of 
the Plan, to determine the Eligible 



Persons who shall be issued Options, the times when Options shall be granted 
and within which they may be exercised, the prices at which Options shall be 
exercised, the number of shares of Common Stock to be subject to each Option 
and whether an Option shall be treated as an incentive stock option or a 
non-qualified stock option.  The Board shall also have the authority, subject 
to the express provisions of the Plan, to amend the Plan, to determine the 
terms and provisions of the respective option agreements, which may but need 
not be identical, to construe the respective option agreements and the Plan, 
and to make all other determinations in the judgment of the Board necessary 
or desirable for the administration of the Plan.  The Board may correct any 
defect or supply any omission or reconcile any inconsistency in the Plan or 
in any option agreement in the manner and to the extent it shall deem 
expedient to implement the Plan and shall be the sole and final judge of such 
expediency. The Board, in its discretion, may delegate its power, duties and 
responsibilities to a committee, consisting solely of two or more 
"Non-Employee Directors" (as hereinafter defined).  If a committee is so 
appointed, all references to the Board herein shall mean and relate to such 
committee.  The existence of such a committee shall not affect the power or 
authority of the Board to administer the Plan.  For the purposes of the Plan, 
the term "Non-Employee Director" shall have the meaning ascribed to it in 
paragraph (b)(3) of Rule 16b-3 promulgated under the Securities Exchange Act 
of 1934, as amended (the "Exchange Act"), as such term is interpreted from 
time to time.

    4.   Type of Option.

         Options granted pursuant to the Plan shall be authorized by action 
of the Board and may be designated as either incentive stock options meeting 
the requirements of Section 422 of the Code or non-qualified stock options 
which are not intended to meet the requirements of such Section 422 of the 
Code, the designation to be in the sole discretion of the Board.  Options 
designated as incentive stock options that fail to continue to meet the 
requirements of Section 422 of the Code shall be redesignated as 
non-qualified stock options automatically without further action by the Board 
on the date of such failure to continue to meet the requirements of Section 
422 of the Code.

    5.   Eligibility.

         Options designated as incentive stock options may be granted only to 
Eligible Persons who are officers or employees of the Company or of any 
subsidiary.  Directors who are not otherwise employees of the Company or a 
subsidiary shall not be eligible to be granted incentive stock options 
pursuant to the Plan.  Options designated as non-qualified stock options may 
be granted to any Eligible Person.

         The Board shall take into account such factors as it may deem 
relevant in determining the number of shares of Common Stock to be included 
in an Option to be granted to any Eligible Person.

    6.   Restrictions on Options.

         Incentive stock options (but not non-qualified stock options) 
granted under this Plan shall be subject to the following restrictions:



         (a)  Limitation on Number of Shares.  The aggregate fair market 
value of the shares of Common Stock with respect to which incentive stock 
options are granted (determined as of the date the incentive stock options 
are granted), exercisable for the first time by an individual during any 
calendar year shall not exceed $100,000.  If an incentive stock option is 
granted pursuant to which the aggregate fair market value of shares with 
respect to which it first becomes exercisable in any calendar year by an 
individual exceeds such $100,000 limitation, the portion of such option which 
is in excess of the $100,000 limitation shall be treated as a non-qualified 
stock option pursuant to Section 422(d)(1) of the Code.  In determining the 
fair market value under this clause (a), the provisions of Section 8 hereof 
shall apply.  In the event that an individual is eligible to participate in 
any other stock option plan of the Company or any subsidiary of the Company 
which is also intended to comply with the provisions of Section 422 of the 
Code, such $100,000 limitation shall apply to the aggregate number of shares 
for which incentive stock options may be granted under this Plan and all such 
other plans.

         (b)  Ten Percent Stockholder.  If any Eligible Person to whom an 
incentive stock option is granted pursuant to the provisions of the Plan is 
on the date of grant the owner of stock (as determined under Section 424(d) 
of the Code) possessing more than 10% of the total combined voting power of 
all classes of stock of the Company or any subsidiary of the Company, then 
the following special provisions shall be applicable to the incentive stock 
options granted to such individual:

              (i)  The Option price per share subject to such Options shall 
be not less than 110% of the fair market value of the shares of Common Stock 
with respect to which Options are granted (determined as of the date such 
Option was granted).  In determining the fair market value under this clause 
(i), the provisions of Section 8 hereof shall apply.

              (ii) The Option by its terms shall not be exercisable after the 
expiration of five years from the date such Option is granted.

    7.   Option Agreement; Disqualifying Dispositions.

         (a)  Each Option shall be evidenced by an option agreement, in a 
form approved from time to time by the Board (the "Agreement"), duly executed 
on behalf of the Company and by the optionee to whom such Option is granted, 
which Agreement shall comply with and be subject to the terms and conditions 
of the Plan.  The Agreement may contain such other terms, provisions and 
conditions which are not inconsistent with the Plan as may be determined by 
the Board; provided that Options designated as incentive stock options shall 
meet all of the conditions for incentive stock options as defined in Section 
422 of the Code.  No Option shall be granted within the meaning of the Plan 
and no purported grant of any Option shall be effective until the Agreement 
shall have been duly executed on behalf of the Company and the optionee.

         (b)  If an optionee makes a "disposition" (within the meaning of 
Section 424(c) of the Code) of shares of Common Stock issued upon exercise of 
an incentive stock option within two years from the date of grant or within 
one year from the date the shares of Common Stock are 



transferred to the optionee, the optionee shall, within ten days of 
disposition, notify the Board and deliver to it any withholding and 
employment taxes due. However, if the optionee is a person subject to Section 
16(b) of the Exchange Act, delivery of any withholding and employment taxes 
due may be deferred until ten days after the date any income on the 
disposition is recognized under Section 83 of the Code.  The Company may 
cause a legend to be affixed to certificates representing shares of Common 
Stock issued upon exercise of incentive stock options to ensure that the 
Board receives notice of disqualifying dispositions.

    8.   Option Price.

         (a)  The Option price or prices of shares of the Common Stock for 
Options designated as non qualified stock options shall be as determined by 
the Board.

         (b)  Subject to the conditions set forth in Section 6(b) hereof, the 
Option price or prices of shares of the Company's Common Stock designated as 
incentive stock options shall be at least the fair market value of such 
Common Stock on the date the Option is granted as determined by the Board in 
accordance with the Regulations promulgated under Section 422 of the Code.

         (c)  If such shares are then listed on any national securities 
exchange, the fair market value shall be the mean between the high and low 
sales prices, if any, on the largest such exchange on the date of the grant 
of the Option or, if there are no such sales on such date, shall be 
determined by taking a weighted average of the means between the highest and 
lowest sales prices on the nearest date before and the nearest date after the 
date of grant in accordance with Section 25.2512-2 of the Regulations.  If 
the shares are not then listed on any such exchange, the fair market value of 
such shares shall be the mean between the closing "Bid" and the closing "Ask" 
prices, if any, as reported in the National Association of Securities Dealers 
Automated Quotation System ("NASDAQ") for the date of the grant of the 
Option, or, if there are no such prices on such date, shall be determined by 
taking a weighted average of the means between the highest and lowest sales 
prices on the nearest date before and the nearest date after the date of 
grant in accordance with Section 25.2512-2 of the Regulations.  If the shares 
are not then either listed on any such exchange or quoted in NASDAQ, the fair 
market value shall be the mean between the average of the "Bid" and "Ask" 
prices, if any, as reported in the National Association of Securities Dealers 
National Daily Quotation Service for the date of the grant of the Option, or, 
if there are no such prices on such date, shall be determined by taking a 
weighted average of the means between the highest and lowest sales prices on 
the nearest date before and the nearest date after the date of grant in 
accordance with Section 25.2512-2 of the Regulations. If the fair market 
value cannot be determined under the preceding three sentences, it shall be 
determined in good faith by the Board in accordance with Section 422 of the 
Code.

    9.   Manner of Payment; Manner of Exercise.

         (a)  Options granted under the Plan may provide for the payment of 
the exercise price by delivery of (i) cash or a check payable to the order of 
the Company in an amount equal to the exercise price of such Options, (ii) 
shares of Common Stock owned by the optionee having a fair 



market value (at the date of exercise) equal in amount to the exercise price 
of the Options being exercised, or (iii) any combination of (i) and (ii).  
The fair market value of any shares of Common Stock which may be delivered 
upon exercise of an Option shall be determined by the Board in accordance 
with Section 8 hereof.

         (b)  To the extent that an Option is exercisable, Options may be 
exercised in full at one time or in part from time to time, by giving written 
notice, signed by the person or persons exercising the Option, to the 
Company, stating the number of shares with respect to which the Option is 
being exercised, accompanied by payment in full for such shares as provided 
in Section 9(a) hereof.  No exercise of an Option may be made for fewer than 
100 full shares of Common Stock unless such exercise is made for the entire 
fractional amount of a share remaining to be purchased pursuant to such 
Option.  Upon such exercise, delivery of a certificate for paid-up, 
non-assessable shares shall be made by the Company to the person or persons 
exercising the Option within 20 business days after receipt of such notice by 
the Company.

    10.  Exercise of Options.

         Each Option granted under the Plan shall, subject to Sections 11(b), 
13 and 16 hereof, be exercisable at such time or times and during such period 
as shall be set forth in the Agreement; provided, however, that except as 
otherwise provided pursuant to the provisions of Section 6(b) hereof, no 
Option granted under the Plan shall have a term in excess of ten years from 
the date of grant.

    11.  Term of Options; Exercisability.

         (a)  Term.

              (i)  Each Option shall expire on a date determined by the Board 
which is not more than ten years from the date of the granting thereof, 
except (a) as otherwise provided pursuant to the provisions of Section 6(b) 
hereof, and (b) for earlier termination as herein provided.

              (ii) Except as otherwise provided in this Section 11, an Option 
granted to any optionee who ceases to be an Eligible Person for any reason 
shall terminate on the earlier of (i) three (3) months after the date such 
optionee ceased to be an Eligible Person, or (ii) the date on which the 
Option expires by its terms.

              (iii)     If an optionee ceases to be an Eligible Person 
because the Company has terminated his or her status with the Company for 
cause (as such term is defined in any employment or similar agreement between 
such optionee and the Company or, if there is no such agreement, or such 
agreement does not contain provisions relating to termination or removal for 
cause, as such term is defined by the law of the State of Delaware), such 
Option will, to the extent not terminated, be deemed to have terminated on 
the date immediately preceding the date the optionee ceased to be an Eligible 
Person.



              (iv) If an optionee ceases to be an Eligible Person because the 
optionee has become disabled (within the meaning of Section 22(e)(3) of the 
Code), such Option shall terminate on the earlier of (i) one year after the 
date such optionee ceased to be an Eligible Person, or (ii) the date on which 
the Option expires by its terms.

              (v)  In the event of the death of any optionee, such Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         (b)  Exercisability.

              (i)  Except as otherwise provided in this Section 11(b), an 
Option granted to an optionee who thereafter ceases to be an Eligible Person 
shall be exercisable only to the extent that the right to purchase shares 
under such Option is exercisable on the date such optionee ceased to be an 
Eligible Person.

              (ii) An Option granted to an optionee who ceases to be an 
Eligible Person because he or she has become disabled (as such term is 
defined in any employment or similar agreement between such optionee and the 
Company or, if there is no such agreement, or such agreement does not contain 
provisions relating to termination or removal for disability, as determined 
by the Board) shall be immediately exercisable as to the full number of 
shares covered by such Option, whether or not under the provisions of the 
Plan or Agreement such Option was otherwise exercisable as of the date of 
disability.

              (iii)     In the event of the death of an optionee, the Option 
granted to such optionee may be exercised as to the full number of shares 
covered by such Option, whether or not under the provisions of the Plan or 
Agreement the optionee was otherwise exercisable at the date of his or her 
death, by the executor, administrator or personal representative of such 
optionee, or by any person or persons who acquired the right to exercise such 
Option by bequest or inheritance or by reason of the death of such optionee.

              (iv) In addition to the acceleration of the exercisability of 
Options pursuant to this Section 11(b) and Section 13(b)(ii) hereof, the 
Board shall have the right, in the exercise of its discretion and for any 
reason, and with the consent of the optionee, to accelerate the date on which 
Options shall be exercisable.

    12.  Transferability.

         The right of any optionee to exercise any Option granted to him or 
her shall not be assignable or transferable by such optionee other than by 
will or the laws of descent and distribution, and any such Option shall be 
exercisable during the lifetime of such optionee only by him or her.  Any 
Option granted under the Plan shall be null and void and without effect upon 
the bankruptcy of the optionee to whom the Option is granted, or upon any 
attempted assignment or transfer, except as herein provided, including, 
without limitation, any purported assignment, whether voluntary or by 



operation of law, pledge, hypothecation or other disposition, or levy of 
execution, attachment, trustee process or similar process, whether legal or 
equitable, upon such Option.  The Board shall have discretion to grant any 
Option that is not designated as an incentive stock option, free of any or 
all of the restrictions described in this Section.

    13.  Recapitalization, Reorganizations and the Like.

         (a)  In the event that after November 25, 1997 the outstanding 
shares of the Common Stock are changed into or exchanged for a different 
number or kind of shares or other securities of the Company by reason of any 
reorganization, recapitalization, reclassification, stock split, combination 
of shares, or dividends payable in capital stock, appropriate and equitable 
adjustment shall be made by the Board, in its sole discretion, in the number 
and kind of shares as to which Options may be granted under the Plan and as 
to which outstanding Options or portions thereof then unexercised shall be 
exercisable.  Such adjustment in outstanding Options shall be made without 
change in the total price applicable to the unexercised portion of such 
Options and with a corresponding adjustment in the Option price per share.

         (b)  (i)  In addition, unless otherwise determined by the Board in 
its sole discretion, in the case of any (I) merger or consolidation pursuant 
to which the Company's stockholders shall receive cash or securities of 
another corporation and less than 50% of the outstanding capital stock of the 
surviving corporation pursuant to such merger or consolidation shall be owned 
by the stockholders of the Company, (II) sale or conveyance to another entity 
of all or substantially all of the property and assets of the Company or 
(III) Change in Control of the Company, the Company shall, or shall cause 
such surviving corporation or the purchaser(s) of the Company's assets to, 
deliver to the optionee the same kind of consideration that is delivered to 
the stockholders of the Company as a result of such merger, consolidation, 
sale, conveyance or Change in Control, or the Board may cancel all 
outstanding Options in exchange for consideration in cash or marketable 
securities, which consideration in both cases shall be equal in value to the 
value of those shares of stock or other securities the optionee would have 
received had the Option been exercised (but only to the extent then 
exercisable) and had no disposition of the shares acquired upon such exercise 
been made prior to such merger, consolidation, sale, conveyance or Change in 
Control, less the Option price therefor or, in lieu thereof, the Board shall 
give the optionee at least twenty days prior written notice of any such 
transaction in order to enable the optionee to exercise the exercisable 
portion, if any, of the Option.  Upon receipt of such consideration effective 
on the date specified in such notice, all Options (whether or not then 
exercisable) shall immediately terminate and be of no further force or 
effect. The value of the stock or other securities the optionee would have 
received if the Option had been exercised shall be determined in good faith 
by the Board, and in the case of shares of Common Stock, in accordance with 
the provisions of Section 8 hereof.

              (ii) The Board shall also have the power and right to 
accelerate the exercisability of any Options, notwithstanding any limitations 
in this Plan or in the Agreement upon such merger, consolidation, sale, 
conveyance or Change in Control.

         (c)  A "Change in Control" shall be deemed to have occurred if any 
person, or any 



two or more persons acting as a group, and all affiliates of such person or 
persons, who prior to such time Beneficially Owned (as defined in Rule 13d-3 
under the Exchange Act) less than 40% of the then outstanding Common Stock, 
shall acquire such additional shares of Common Stock in one or more 
transactions, or series of transactions, such that following such transaction 
or transactions, such person or group and affiliates Beneficially Own 50% or 
more of the Common Stock outstanding.

         (d)  If by reason of a corporate merger, consolidation, acquisition 
of property or stock, separation, reorganization, or liquidation, the Board 
shall authorize the issuance or assumption of a stock option or stock options 
in a transaction to which Section 424(a) of the Code applies, then, 
notwithstanding any other provision of the Plan, the Board may grant an 
option or options upon such terms and conditions as it may deem appropriate 
for the purpose of assumption of the old Option, or substitution of a new 
option for the old Option, in conformity with the provisions of such Section 
424(a) of the Code and the Regulations thereunder, and any such option shall 
not reduce the number of shares otherwise available for issuance under the 
Plan.  In the event of such issuance or assumption, the provisions of Section 
13(b) hereof shall not be applicable.

    14.  No Special Employment Rights.

         Nothing contained in the Plan or in any Option granted under the 
Plan shall confer upon any optionee any right with respect to the 
continuation of his or her employment by the Company or any subsidiary or 
interfere in any way with the right of the Company or any subsidiary, subject 
to the terms of any separate employment agreement to the contrary, at any 
time to terminate such employment or to increase or decrease the compensation 
of the Option holder from the rate in existence at the time of the grant of 
an Option.  Whether an authorized leave of absence, or absence in military or 
government service, shall constitute termination of employment for purposes 
of any Option shall be determined by the Board at the time of such occurrence.

    15.  Withholding.

         The Company's obligation to deliver shares upon the exercise of any 
Option granted under the Plan shall be subject to the Option holder's 
satisfaction of any applicable federal, state and local income and employment 
tax withholding requirements.  The Company and optionee may agree to withhold 
shares of Common Stock purchased upon exercise of an Option to satisfy the 
above-mentioned withholding requirements.

    16.  Restrictions on Exercise of Options and Issuance of Shares.

         (a)  Notwithstanding the provisions of Sections 9 and 11 hereof, an 
Option cannot be exercised, and the Company may delay the issuance of shares 
covered by the exercise of an Option and the delivery of a certificate for 
such shares, until one of the following conditions shall be satisfied:

              (i)  The shares with respect to which such Option has been 
exercised are at the time of the issuance of such shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or



              (ii) Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of such shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         (b)  The Company shall be under no obligation to qualify shares or 
to cause a registration statement or a post-effective amendment to any 
registration statement to be prepared for the purpose of covering the 
issuance of shares in respect of which any Option may be exercised or to 
cause the issuance of such shares to be exempt from registration and 
qualification under applicable federal and state securities acts now in force 
or as hereinafter amended, except as otherwise agreed to by the Company in 
writing in its sole discretion.

    17.  Purchase for Investment; Rights of Holder on Subsequent Registration.

         Unless and until the shares to be issued upon exercise of an Option 
granted under the Plan have been effectively registered under the Securities 
Act of 1933, as amended (the "1933 Act"), as now in force or hereafter 
amended, the Company shall be under no obligation to issue any shares covered 
by any Option unless the person who exercises such Option, in whole or in 
part, shall give a written representation and undertaking to the Company 
which is satisfactory in form and scope to counsel for the Company and upon 
which, in the opinion of such counsel, the Company may reasonably rely, that 
he or she is acquiring the shares issued pursuant to such exercise of the 
Option for his or her own account as an investment and not with a view to, or 
for sale in connection with, the distribution of any such shares, and that he 
or she will make no transfer of the same except in compliance with any rules 
and regulations in force at the time of such transfer under the 1933 Act, or 
any other applicable law, and that if shares are issued without such 
registration, a legend to this effect may be endorsed upon the securities so 
issued.

         In the event that the Company shall, nevertheless, deem it necessary 
or desirable to register under the 1933 Act or other applicable statutes any 
shares with respect to which an Option shall have been exercised, or to 
qualify any such shares for exemption from the 1933 Act or other applicable 
statutes, then the Company may take such action and may require from each 
optionee such information in writing for use in any registration statement, 
supplementary registration statement, prospectus, preliminary prospectus, 
offering circular or any other document that is reasonably necessary for such 
purpose and may require reasonable indemnity to the Company and its officers 
and directors from such holder against all losses, claims, damages and 
liabilities arising from such use of the information so furnished and caused 
by any untrue statement of any material fact therein or caused by the 
omission to state a material fact required to be stated therein or necessary 
to make the statements therein not misleading in the light of the 
circumstances under which they were made.

    18.  Loans.

         At the discretion of the Board, the Company may loan to the 
optionee, or pay to the optionee as a bonus, some or all of the purchase 
price of the shares acquired upon exercise of an Option, the terms of such 
loans or bonus to be at the discretion of the Board.



    19.  Modification of Outstanding Options.

         Subject to any applicable limitations contained herein, the Board 
may authorize the amendment of any outstanding Option with the consent of the 
optionee when and subject to such conditions as are deemed to be in the best 
interests of the Company and in accordance with the purposes of the Plan. 
Without limiting the foregoing, the Board shall have the authority to effect, 
at any time and from time to time, with the consent of the affected 
optionees, the cancellation of any or all outstanding Options under the Plan 
and to grant in substitution therefor new Options under the Plan covering the 
same or different numbers of Shares and having, at the discretion of the 
Board and subject to Sections 6 and 8 hereof, an exercise price, in the case 
of Options designated as non-qualified stock options, as shall be determined 
by the Board and, in the case of Options designated as incentive stock 
options, of not less than one hundred percent (100%) of the fair market value 
of the Common Stock on the new grant date.

    20.  Approval of Board and Stockholders.

         The Plan shall become effective upon adoption by the Board and the 
stockholders of the Company; provided, however, that the Plan shall be 
submitted for approval by the stockholders of the Company within 12 months 
after the date of adoption of the Plan by the Board.  If the stockholders of 
the Company fail to approve the Plan within 12 months after the date of 
adoption of the Plan by the Board, the Plan and all stock options granted 
thereunder shall be and become null and void and of no further force or 
effect.

    21.  Termination and Amendment of Plan.

         Unless sooner terminated as herein provided, the Plan shall 
terminate ten years from the earlier of (x) the date on which the Plan was 
duly adopted by the Board, and (y) the date on which the Plan was duly 
approved by the stockholders of the Company.  The Board may at any time 
terminate the Plan or make such modification or amendment thereof as it deems 
advisable; provided, however, (i) the Board may not, without the approval of 
the stockholders of the Company obtained in the manner stated in Section 20 
hereof, increase the maximum number of shares for which Options may be 
granted or change the designation of the class of persons eligible to receive 
Options under the Plan, and (ii) any such modification or amendment of the 
Plan shall be approved by a majority of the stockholders of the Company to 
the extent that such stockholder approval is necessary to comply with 
applicable provisions of the Code, rules promulgated pursuant to Section 16 
of the Exchange Act (if any), applicable state law, or applicable NASD or 
exchange listing requirements.  Termination or any modification or amendment 
of the Plan shall not, without the consent of an optionee, affect his or her 
rights under an Option theretofore granted to him or her.

    22.  Duties of the Company.

         The Company shall at all times keep available for issuance or 
delivery such number of shares of Common Stock as will be sufficient to 
satisfy the requirements of the Plan.



    23.  Limitation of Rights in the Option Shares.

         An optionee shall not be deemed for any purpose to be a stockholder 
of the Company with respect to any of the Options until (x) the Option shall 
have been exercised with respect thereto (including payment to the Company of 
the exercise price) and (y) the earlier to occur of (i) the delivery by the 
Company to the optionee of a certificate therefor, or (ii) the date on which 
the Company is required to deliver a certificate pursuant to Section 9(b) 
hereof.

    24.  Governing Law.

         The Plan and all Options shall be governed by and construed under 
the laws of the State of Delaware, without giving effect to principles of 
conflicts of law.

    25.  Notices.

         Any communication or notice required or permitted to be given under 
the Plan shall be in writing, and mailed by registered or certified mail or 
delivered by hand, if to the Company, to the attention of the President at 
the Company's principal place of business; and, if to an optionee, to his or 
her address as it appears on the records of the Company.

    26.  Headings.

         The headings contained in this Plan are for convenience of reference 
only and in no way define, limit or describe the scope or intent of the Plan 
or in any way affect this Agreement.

                         NON-QUALIFIED STOCK OPTION AGREEMENT
                              PURSUANT TO AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    AGREEMENT made _______________, 19__, by and between AYURCORE, INC., a 
Delaware corporation with its principal place of business at 1737 N. First 
Street, Suite 290, San Jose, California 95112 (the "Company"), and the 
undersigned employee, agent or director of, or consultant to, the Company or 
any of its subsidiaries (the "Optionee").

                                 W I T N E S S E T H:

    WHEREAS, the Company considers it desirable and in its best interests 
that the Optionee be encouraged to acquire an ownership interest in the 
Company, and thereby have an added incentive to advance the interests of the 
Company, by the grant of an option to purchase shares of the Company's common 
stock, par value $.001 per share (the "Common Stock"), in accordance with the 
Company's 1997 Stock Option Plan (the "Plan") on the terms and conditions 
hereinafter set forth; and

    WHEREAS, the Plan provides that each option granted thereunder is to be 
evidenced by an option agreement, setting forth the terms and conditions of 
the option.

    NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements contained herein, the Company and the Optionee 
hereby agree as follows:

    1.   Grant of Option.

    The Company hereby grants to the Optionee the right, privilege and option 
(the "Option") to purchase that number of shares of the Company's Common 
Stock set forth on the signature page hereof (the "Shares") at the purchase 
price per Share set forth on the signature page hereof (the "Purchase 
Price"), in the manner and subject to the conditions hereinafter provided and 
contained in the Plan.  In the event of any inconsistencies between the Plan 
and this Agreement, the Plan shall govern.  Such number of Shares issuable 
upon exercise of the Option shall be subject to adjustment as provided in 
Section 7 below.  The Option is not intended to be an incentive stock option 
meeting the requirements of Section 422 of the Internal Revenue Code of 1986, 
as amended (the "Code").

    2.   Time of Exercise of Option.

    Subject to the provisions of Section 4 below, the Option shall vest and 
become exercisable in accordance with the schedule set forth on the signature 
page hereof; provided, however, that upon a Change in Control (as defined in 
the Plan) of the Company, the Option shall be immediately exercisable.  To 
the extent the Option is not exercised by the Optionee when it becomes 
exercisable, it shall continue in full force and effect until the Expiration 
Date (as hereinafter defined).



    3.   Method of Exercise.

    The Option shall be exercised by written notice in the form of Exhibit A 
hereto directed to the Company at the Company's address set forth above, duly 
executed by the Optionee, specifying the number of shares being purchased and 
accompanied by either (i) cash or check payable to the order of the Company 
in full payment of the Purchase Price for the number of Shares being 
purchased, or (ii) certificate(s), duly endorsed for transfer to the Company 
with signature guaranteed, for that number of previously acquired Shares 
having an aggregate fair market value as determined in accordance with the 
Plan ("Fair Market Value"), on the date of exercise equal to the full 
Purchase Price for the number of Shares being purchased, or (iii) a 
combination of (i) and (ii).

    The Option shall not be exercisable at any time in an amount less than 
100 Shares (or the remaining fraction of a Share then covered by and 
purchasable under the Option if less than 100 Shares).

    4.   Term of Options; Exercisability.

         A.   Term.

              1.   This Option shall expire on the date set forth on the 
signature page hereto (the "Expiration Date"), subject to earlier termination 
as herein provided.

              2.   Except as otherwise provided in this Section 4, if the 
Optionee's employment by, or retention as an agent, director of, or 
consultant to, the Company and its subsidiaries is terminated for any reason, 
the Option shall terminate on the earlier of (i) three months after the date 
the Optionee's employment by or retention as an agent, director of, or 
consultant to, the Company and its subsidiaries is terminated, or (ii) the 
date on which the Option expires by its terms.

              3.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries for cause (as such term is defined in any employment 
agreement or similar agreement between the Optionee and the Company or, if 
there is no such employment or similar agreement, or the employment or 
similar agreement does not have provisions relating to termination for cause, 
as such term is defined by the law of the State of New York), the Option will 
to the extent not terminated be deemed to have terminated on the date 
immediately preceding the date the Optionee's employment by, or retention as 
an agent, director of, or consultant to, the Company is terminated by the 
Company and its subsidiaries.

              4.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries because the Optionee has become disabled (within the meaning 
of Section 22(e)(3) of the Code), the Option shall terminate on the earlier 
of (i) one year after the date the Optionee's employment by, or retention as 

                                         2


an agent, director of, or consultant to, the Company and its subsidiaries is 
terminated, or (ii) the date on which the Option expires by its terms.

              5.   In the event of the death of the Optionee, the Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         B.   Exercisability.

              1.   Except as provided in this Section 4.B., if the Optionee's 
employment by, or retention as an agent, director of, or consultant to, the 
Company and its subsidiaries is terminated, the Option shall be exercisable 
only to the extent that the right to purchase Shares under the Option is 
exercisable on the date the Optionee's employment by, or retention as an 
agent, director of, or consultant to, the Company and its subsidiaries is 
terminated.

              2.   If the Optionee's employment by, or retention as an agent, 
director of, or consultant to, the Company is terminated by the Company and 
its subsidiaries because the Optionee has become disabled (as such term is 
defined in any employment or similar agreement between the Optionee and the 
Company or, if there is no such employment or similar agreement, or the 
employment or similar agreement does not contain provisions relating to 
termination for disability, as determined by the Board of Directors of the 
Company), the Option shall be immediately exercisable as to the full number 
of Shares covered by the Option, whether or not under the provisions of 
Section 2 hereof the Option was otherwise exercisable as of the date of 
disability.

              3.   In the event of the death of the Optionee, the Option 
granted to the Optionee shall be immediately exercisable as to the full 
number of Shares covered thereby, whether or not under the provisions of 
Section 2 hereof the Optionee was entitled to do so at the date of his death, 
by the executor, administrator or personal representative of the Optionee, or 
by any person or persons who acquired the right to exercise such Option by 
bequest or inheritance or by reason of the death of the Optionee.

    5.   Non-Transferability.

    [This provision may be deleted or modified at the discretion of the Board 
or Committee granting the Option].

    The right of the Optionee to exercise the Option shall not be assignable 
or transferable by the Optionee otherwise than by will or the laws of descent 
and distribution, and the Option may be exercised during the lifetime of the 
Optionee only by the Optionee.  The Option shall be null and void and without 
effect upon the bankruptcy of the Optionee or upon any attempted assignment 
or transfer, except as hereinabove provided, including without limitation, 
any purported assignment, whether voluntary or by operation of law, pledge, 
hypothecation or other disposition contrary to the 

                                         3


provisions hereof, or levy of execution, attachment, trustee process or 
similar process, whether legal or equitable, upon the Option.

    6.   Representation Letter and Investment Legend.

         A.   Notwithstanding the provisions of Sections 3 and 4 hereof, the 
Option cannot be exercised, and the Company may delay the issuance of the 
Shares covered by the exercise of the Option and the delivery of a 
certificate for the Shares, until one of the following conditions shall be 
satisfied:

              1.   The Shares with respect to which the Option has been 
exercised are at the time of the issuance of the Shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or 

              2.   Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of the Shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         B.   In the event that for any reason the Shares to be issued upon 
exercise of the Option shall not be effectively registered under the 
Securities Act of 1933, as amended (the "1933 Act"), upon any date on which 
the Option is exercised in whole or in part, the Optionee shall give a 
written representation to the Company in the form attached hereto as Exhibit 
A and the Company shall place an "investment legend," so-called, as described 
in Exhibit A, upon any certificate for the Shares issued by reason of such 
exercise.  In the event that the Company shall, nevertheless, deem it 
necessary or desirable to register under the 1933 Act or other applicable 
statutes the Shares with respect to which the Option shall have been 
exercised, or to qualify the Shares for exemption from the 1933 Act or other 
applicable statutes, then the Company may take such action and may require 
from the Optionee such information in writing for use in any registration 
statement, supplementary registration statement, prospectus, preliminary 
prospectus, offering circular or any other document that is reasonably 
necessary for such purpose and may require reasonable indemnity to the 
Company and its officers and directors from the Optionee against all losses, 
claims, damages and liabilities arising from such use of the information so 
furnished and caused by any untrue statement of any material fact therein or 
caused by the omission to state a material fact required to be stated therein 
or necessary to make the statements therein not misleading in the light of 
the circumstances under which they were made.

         C.   The Company shall be under no obligation to qualify the Shares 
or to cause a registration statement or a post-effective amendment to any 
registration statement to be prepared for the purposes of covering the issue 
of the Shares or to cause the issuance of the Shares to be exempt from 
registration and qualification under applicable federal and state securities 
acts now in force or as hereinafter amended, except as otherwise agreed to by 
the Company in writing in its sole discretion and, accordingly, the Company 
may delay the issuance of the Shares covered by the 

                                         4


exercise of the Option and the delivery of a certificate for the Shares until 
the Company shall have determined that all conditions to the issuance of the 
Shares shall have been satisfied.

    7.   Adjustment in and Changes in Common Stock.

    Subject to the Plan, if the outstanding shares of the Common Stock are 
changed into or exchanged for a different number or kind of shares or other 
securities of the Company by reason of any reorganization, recapitalization, 
reclassification, stock split, combination of shares, or dividends payable in 
capital stock, appropriate and equitable adjustment shall be made by the 
Board of Directors of the Company, in its sole discretion, in the number and 
kind of shares as to which the Option or portion thereof then unexercised 
shall be exercisable.  Such adjustment in the Option shall be made without 
change in the total price applicable to the unexercised portion of such the 
Option and with a corresponding adjustment in the Option price per share.

    8.   Effect on Other Rights.

    This Agreement shall in no way affect the Optionee's participation in or 
benefits under any other plan or benefit program maintained or provided by 
the Company.  Nothing in this Agreement shall be construed to give the 
Optionee any right to any additional options other than in the sole 
discretion of the Board of Directors of the Company or to confer on the 
Optionee any right to continue in the employ of the Company or any subsidiary 
thereof or to continue to be retained as an agent, director of, or consultant 
to, the Company, or to be evidence of any agreement or understanding, express 
or implied, that the Company will employ or continue to retain the Optionee 
in any particular position or at any particular rate of remuneration, or for 
any particular period of time or to interfere in any way with the right of 
the Company or a subsidiary thereof (or the right of the Optionee) to 
terminate the employment or retention of the Optionee at any time, with or 
without cause, notwithstanding the possibility that the Option may thereby be 
terminated entirely.

    9.   Rights as a Shareholder.

    The Optionee shall have no rights as a shareholder with respect to any 
Shares which may be purchased by exercise of the Option until (x) the Option 
shall have been exercised with respect thereto (including payment to the 
Company of the Purchase Price), and (y) the earlier to occur of (i) delivery 
by the Company to the optionee of a certificate therefor or (ii) the date on 
which the Company is required to deliver a certificate pursuant to the Plan 
and this Agreement.  Except as otherwise expressly provided in the Plan, no 
adjustment shall be made for dividends or other rights for which the record 
date is prior to the date such certificate is issued or required to be issued 
in accordance with the Plan.

    10.  Governing Law.

    THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE 
APPLICABLE TO CONTRACTS TO BE MADE AND PERFORMED ENTIRELY 

                                         5



THEREIN WITHOUT REFERENCE TO CONFLICT OF LAWS PRINCIPLES.

    11.  Withholding Taxes.

    Whenever Shares are to be issued upon exercise of the Option, the Company 
shall have the right to require the Optionee to remit to the Company an 
amount sufficient to satisfy all federal, state and local withholding tax 
requirements, if any, prior to the delivery of any certificate or 
certificates for such Shares.  The Company may agree to permit the Optionee 
to withhold Shares purchased upon exercise of this Option to satisfy the 
above-mentioned withholding requirement.

    12.  Headings.

    The headings contained in this Agreement are for convenience of reference 
only and in no way define, limit or describe the scope or intent of this 
Agreement or in any way affect this Agreement.

    13.  Binding Effect.

    This Agreement shall inure to the benefit of and be binding upon the 
parties hereto and their respective heirs, executors, administrators, 
successors and assigns.

                                         6

 
    IN WITNESS WHEREOF, the Company has caused this Agreement to be executed, 
and the Optionee has hereunto set his or her hand and seal, all as of the day 
and year first above written.

                                  Date:______________________

AyurCore, Inc.
1737 N. First Street, Suite 290
San Jose, California 95112

Ladies and Gentlemen:

    I hereby elect to purchase ____ shares of the Common Stock, $.001 par 
value per share, of AyurCore, Inc. (the "Company") under the option granted 
to me pursuant to the Stock Option Agreement, dated _______________, ____, 
under the Company's 1997 Stock Option Plan.

    Enclosed is [cash] [a check] in the amount of $______.___ [______ 
shares of the Company's Common Stock] in full payment of the shares being 
purchased ($________ per share x ____ shares).



    Please deliver certificates representing the shares being purchased to me 
at:

              _____________________________

              _____________________________

              _____________________________

    I hereby acknowledge that I have been informed as follows:

         1.   The shares of common stock of the Company to be issued to me 
pursuant to the exercise of said option have not been registered under the 
Securities Act of 1933, as amended (the "1933 Act"), and accordingly, must be 
held indefinitely unless such shares are subsequently registered under the 
1933 Act, or an exemption from such registration is available.

    2.   Routine sales of securities made in reliance upon Rule 144, if 
applicable, under the 1933 Act can be made only after the holding period and 
in limited amounts in accordance with the terms and conditions provided by 
that Rule, and in any sale to which that Rule is not applicable, registration 
or compliance with some other exemption under the 1933 Act will be required.



    3.   The Company is under no obligation to me to register the shares or 
to comply with any such exemptions under the 1933 Act.

    4.   The availability of Rule 144, if applicable, is dependent upon 
adequate current public information with respect to the Company being 
available and, at the time that I may desire to make a sale pursuant to the 
Rule, the Company may neither wish nor be able to comply with such 
requirement.

    In consideration of the issuance of certificates for the shares to me, I 
hereby represent and warrant that I am acquiring such shares for my own 
account for investment, and that I will not sell, pledge, transfer or 
otherwise dispose of such shares in the absence of an effective registration 
statement covering the same, except as permitted by the provisions of Rule 
144, if applicable, or some other applicable exemption under the 1933 Act.  
In view of this representation and warranty, I agree that there may be 
affixed to the certificates for the shares to be issued to me, and to all 
certificates issued hereafter representing such shares (until in the opinion 
of counsel, which opinion must be reasonably satisfactory in form and 
substance to counsel for the Company, it is no longer necessary or required) 
a legend as follows:

    "The shares of common stock represented by this certificate have not
    been registered under the Securities Act of 1933, as amended (the
    "Act"), and were acquired by the registered holder, pursuant to a
    representation and warranty that such holder was acquiring such shares
    for his or her own account and for investment, with no intention to
    transfer or dispose of the same, in violation of the registration
    requirements of the Act.  These shares may not be sold, pledged,
    transferred or otherwise disposed of in the absence of an effective
    registration statement under the Act, or an opinion of counsel, which
    opinion is reasonably satisfactory to counsel to the Company, to the
    effect that registration is not required under the Act."

    I further agree that the Company may place a stop order with its Transfer 
Agent, prohibiting the transfer of such shares, so long as the legend remains 
on the certificates representing the shares.

                                  Very truly yours,


                                  ----------------------------------
                                  Optionee:




                                    AYURCORE, INC.

                           INCENTIVE STOCK OPTION AGREEMENT
                              PURSUANT TO AYURCORE, INC.
                                1997 STOCK OPTION PLAN

    AGREEMENT made as of ____________ ___, 19__, by and between AYURCORE, 
INC., a Delaware corporation with its principal place of business at 1737 N. 
First Street, Suite 290, San Jose, California 95112 (the "Company"), and the 
undersigned employee of the Company or any of its subsidiaries (the 
"Optionee").

                                 W I T N E S S E T H:

    WHEREAS, the Company considers it desirable and in its best interests 
that the Optionee be encouraged to acquire an ownership interest in the 
Company, and thereby have an added incentive to advance the interests of the 
Company, by the grant of an option to purchase shares of the Company's common 
stock, par value $.001  per share (the "Common Stock"), in accordance with 
the Company's 1997 Stock Option Plan (the "Plan") on the terms and conditions 
hereinafter set forth; and

    WHEREAS, the Plan provides that each option granted thereunder is to be 
evidenced by an option agreement, setting forth the terms and conditions of 
the option.

    NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements contained herein, the Company and the Optionee 
hereby agree as follows:

    1.   Grant of Option.

    The Company hereby grants to the Optionee the right, privilege and option 
(the "Option") to purchase that number of shares of the Company's Common 
Stock set forth on the signature page hereto (the "Shares") at the purchase 
price per Share set forth on the signature page hereto (the "Purchase 
Price"), in the manner and subject to the conditions hereinafter provided and 
contained in the Plan.  In the event of any inconsistencies between the Plan 
and this Agreement, the Plan shall govern.  Such number of Shares issuable 
upon exercise of the Option shall be subject to adjustment as provided in 
Section 7 below.  The Option is intended to be an incentive stock option 
meeting the requirements of Section 422 of the Internal Revenue Code of 1986, 
as amended (the "Code").  If for any reason the Option or any part hereof is 
not deemed to be an incentive stock option, to the extent it is not an 
incentive stock option, it shall be treated as a non-qualified stock option.

    2.   Time of Exercise of Option.

    Subject to the provisions of Section 4 below, the Option shall vest and 
become exercisable in accordance with the schedule set forth on the signature 
page hereof; provided, however, that upon 



a Change in Control (as defined in the Plan) of the Company, the Option shall 
be immediately exercisable.  To the extent the Option is not exercised by the 
Optionee when it becomes exercisable, it shall continue in full force and 
effect until the Expiration Date (as hereinafter defined).

    3.   Method of Exercise.

    The Option shall be exercised by written notice in the form of Exhibit A 
hereto, directed to the Company at the Company's address set forth above, 
duly executed by the Optionee, specifying the number of shares being 
purchased and accompanied by either (i) cash or check payable to the order of 
the Company in full payment of the Purchase Price for the number of Shares 
being purchased, or (ii) certificate(s), duly endorsed for transfer to the 
Company with signature guaranteed, for that number of previously acquired 
Shares having an aggregate fair market value as determined in accordance with 
the Plan ("Fair Market Value"), on the date of exercise equal to the full 
Purchase Price for the number of Shares being purchased, or (iii) a 
combination of (i) and (ii).

    The Option shall not be exercisable at any time in an amount less than 100
Shares (or the remaining Shares then covered by and purchasable under the Option
if less than 100 Share).

    4.   Term of Options; Exercisability.

         A.   Term.

              1.   This Option shall expire on the tenth anniversary of the 
date of this agreement (the "Expiration Date"), subject to earlier 
termination as herein provided.

              2.   Except as otherwise provided in this Section 4, if the 
Optionee's employment by the Company and its subsidiaries is terminated for 
any reason, the Option shall terminate on the earlier of (i) three months 
after the date the Optionee's employment by the Company and its subsidiaries 
is terminated, or (ii) the date on which the Option expires by its terms.

              3.   If the Optionee's employment is terminated by the Company 
and its subsidiaries for cause (as such term is defined in any employment 
agreement or similar agreement between the Optionee and the Company or, if 
there is no such employment agreement, or the employment agreement does not 
have provisions relating to termination for cause, as such term is defined by 
the law of the State of Delaware), the Option will to the extent not 
terminated be deemed to have terminated on the date immediately preceding the 
date the Optionee's employment is terminated by the Company and its 
subsidiaries.

              4.   If the Optionee's employment is terminated by the Company 
and its subsidiaries because the Optionee has become disabled (as defined in 
any employment agreement or similar agreement between the Optionee and the 
Company or within the meaning of Section 22(e)(3) of the Code), the Option 
shall terminate on the earlier of (i) one year after the date the Optionee's

                                         2


employment by the Company and its subsidiaries is terminated, or (ii) the 
date on which the Option expires by its terms.

              5.   In the event of the death of the Optionee, the Option 
shall terminate on the earlier of (i) one year after the date of death, or 
(ii) the date on which the Option expires by its terms.

         B.   Exercisability.

              1.   Except as provided in this Section 4.B., if the Optionee's 
employment by the Company and its subsidiaries is terminated, the Option 
shall be exercisable only to the extent that the right to purchase Shares 
under the Option is exercisable on the date the Optionee's employment by the 
Company and its subsidiaries is terminated.

              2.   If the Optionee's employment is terminated by the Company 
and its subsidiaries because the Optionee has become disabled (as such term 
is defined in any employment agreement between the Optionee and the Company 
or, if there is no such employment agreement, or the employment agreement 
does not contain provisions relating to termination for disability, as 
determined by the Board of Directors of the Company), the Option shall be 
immediately exercisable as to the full number of Shares covered by the 
Option, whether or not under the provisions of Section 2 hereof the Option 
was otherwise exercisable as of the date of disability.

              3.   In the event of the death of the Optionee, the Option 
granted to the Optionee shall be immediately exercisable as to the full 
number of Shares covered thereby, whether or not under the provisions of 
Section 2 hereof the Optionee was entitled to do so at the date of his death, 
by the executor, administrator or personal representative of the Optionee, or 
by any person or persons who acquired the right to exercise such Option by 
bequest or inheritance or by reason of the death of the Optionee.

    5.   Non-Transferability.

    The right of the Optionee to exercise the Option shall not be assignable 
or transferable by the Optionee otherwise than by will or the laws of descent 
and distribution, and the Option may be exercised during the lifetime of the 
Optionee only by the Optionee.  The Option shall be null and void and without 
effect upon the bankruptcy of the Optionee or upon any attempted assignment 
or transfer, except as hereinabove provided, including without limitation, 
any purported assignment, whether voluntary or by operation of law, pledge, 
hypothecation or other disposition contrary to the provisions hereof, or levy 
of execution, attachment, trustee process or similar process, whether legal 
or equitable, upon the Option.

    6.   Representation Letter and Investment Legend.

                                         3


         A.   Notwithstanding the provisions of Sections 3 and 4 hereof, the 
Option cannot be exercised, and the Company may delay the issuance of the 
Shares covered by the exercise of the Option and the delivery of a 
certificate for the Shares, until one of the following conditions shall be 
satisfied:

              1.   The Shares with respect to which the Option has been 
exercised are at the time of the issuance of the Shares effectively 
registered or qualified under applicable federal and state securities acts 
now in force or as hereafter amended; or 

              2.   Counsel for the Company shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that the issuance 
of the Shares is exempt from registration and qualification under applicable 
federal and state securities acts now in force or as hereafter amended.

         B.   In the event that for any reason the Shares to be issued upon 
exercise of the Option shall not be effectively registered under the 
Securities Act of 1933, as amended (the "1933 Act"), upon any date on which 
the Option is exercised in whole or in part, the Optionee shall give a 
written representation to the Company in the form attached hereto as Exhibit 
A and the Company shall place an "investment legend," so-called, as described 
in Exhibit A, upon any certificate for the Shares issued by reason of such 
exercise.  In the event that the Company shall, nevertheless, deem it 
necessary or desirable to register under the 1933 Act or other applicable 
statutes the Shares with respect to which the Option shall have been 
exercised, or to qualify the Shares for exemption from the 1933 Act or other 
applicable statutes, then the Company may take such action and may require 
from the Optionee such information in writing for use in any registration 
statement, supplementary registration statement, prospectus, preliminary 
prospectus, offering circular or any other document that is reasonably 
necessary for such purpose and may require reasonable indemnity to the 
Company and its officers and directors from the Optionee against all losses, 
claims, damages and liabilities arising from such use of the information so 
furnished and caused by any untrue statement of any material fact therein or 
caused by the omission to state a material fact required to be stated therein 
or necessary to make the statements therein not misleading in the light of 
the circumstances under which they were made.

         C.   The Company shall be under no obligation to qualify the Shares 
or to cause a registration statement or a post-effective amendment to any 
registration statement to be prepared for the purposes of covering the issue 
of the Shares or to cause the issuance of the Shares to be exempt from 
registration and qualification under applicable federal and state securities 
acts now in force or as hereinafter amended, except as otherwise agreed to by 
the Company in writing in its sole discretion and, accordingly, the Company 
may delay the issuance of the Shares covered by the exercise of the Option 
and the delivery of a certificate for the Shares until the Company shall have 
determined that all conditions to the issuance of the Shares shall have been 
satisfied.

                                         4


    7.   Adjustment in and Changes in Common Stock.

    Subject to the Plan, if the outstanding shares of the Common Stock are 
changed into or exchanged for a different number or kind of shares or other 
securities of the Company by reason of any reorganization, recapitalization, 
reclassification, stock split, combination of shares, or dividends payable in 
capital stock, appropriate and equitable adjustment shall be made by the 
Board of Directors of the Company, in its sole discretion, in the number and 
kind of shares as to which the Option or portion thereof then unexercised 
shall be exercisable.  Such adjustment in the Option shall be made without 
change in the total price applicable to the unexercised portion of such the 
Option and with a corresponding adjustment in the Option price per share.

    8.   Effect on Other Rights.

    This Agreement shall in no way affect the Optionee's participation in or 
benefits under any other plan or benefit program maintained or provided by 
the Company.  Nothing in this Agreement shall be construed to give the 
Optionee any right to any additional options other than in the sole 
discretion of the Board of Directors of the Company or to confer on the 
Optionee any right to continue in the employ of the Company or any subsidiary 
thereof or to be evidence of any agreement or understanding, express or 
implied, that the Company will employ the Optionee in any particular position 
or at any particular rate of remuneration, or for any particular period of 
time or to interfere in any way with the right of the Company or a subsidiary 
thereof (or the right of the Optionee) to terminate the employment of the 
Optionee at any time, with or without cause, notwithstanding the possibility 
that the Option may thereby be terminated entirely.

    9.   Rights as a Shareholder.

    The Optionee shall have no rights as a shareholder with respect to any 
Shares which may be purchased by exercise of the Option until (x) the Option 
shall have been exercised with respect thereto (including payment to the 
Company of the Purchase Price), and (y) the earlier to occur of (i) delivery 
by the Company to the optionee of a certificate therefor or (ii) the date on 
which the Company is required to deliver a certificate pursuant to the Plan 
and this Agreement.  Except as otherwise expressly provided in the Plan, no 
adjustment shall be made for dividends or other rights for which the record 
date is prior to the date such certificate is issued or required to be issued 
in accordance with the Plan.

    10.  Governing Law.

    THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE 
APPLICABLE TO CONTRACTS TO BE MADE AND PERFORMED ENTIRELY THEREIN WITHOUT 
REFERENCE TO CONFLICT OF LAWS PRINCIPLES.

    11.  Withholding Taxes.

                                         5



    Whenever Shares are to be issued upon exercise of the Option, the Company 
shall have the right to require the Optionee to remit to the Company an 
amount sufficient to satisfy all federal, state and local withholding tax 
requirements, if any, prior to the delivery of any certificate or 
certificates for such Shares.  The Company may agree to permit the Optionee 
to withhold Shares purchased upon exercise of this Option to satisfy the 
above-mentioned withholding requirement.

    12.  Headings.

    The headings contained in this Agreement are for convenience of reference 
only and in no way define, limit or describe the scope or intent of this 
Agreement or in any way affect this Agreement.

    13.  Binding Effect.

    This Agreement shall inure to the benefit of and be binding upon the 
parties hereto and their respective heirs, executors, administrators, 
successors and assigns.

    IN WITNESS WHEREOF, the Company has caused this Agreement to be executed,
and the Optionee has hereunto set his or her hand and seal, all as of the day
and year first above written.

AyurCore, Inc.
1737 N. First Street, Suite 290
San Jose, California 95112

Ladies and Gentlemen:

    I hereby elect to purchase ____ shares of the Common Stock, no par value 
per share, of AyurCore, Inc. (the "Company") under the option granted to me 
pursuant to the Incentive Stock Option Agreement, dated as of 
_______________, 199_, under the Company's 1997 Stock Option Plan.

    Enclosed is [cash] [a check] in the amount of $______.___  
[______ shares of the Company's Common Stock] in full payment of the shares 
being purchased ($_______________ per share x ____ shares).



    Please deliver certificates representing the shares being purchased to me 
at:

              _____________________________

              _____________________________

              _____________________________

    I hereby acknowledge that I have been informed as follows:

         1.   The shares of common stock of the Company to be issued to me 
pursuant to the exercise of said option have not been registered under the 
Securities Act of 1933, as amended (the "1933 Act"), and accordingly, must be 
held indefinitely unless such shares are subsequently registered under the 
1933 Act, or an exemption from such registration is available.

    2.   Routine sales of securities made in reliance upon Rule 144, if 
applicable, under the 1933 Act can be made only after the holding period and 
in limited amounts in accordance with the 

                                         7


terms and conditions provided by that Rule, and in any sale to which that 
Rule is not applicable, registration or compliance with some other exemption 
under the 1933 Act will be required.

    3.   The Company is under no obligation to me to register the shares or 
to comply with any such exemptions under the 1933 Act.

    4.   The availability of Rule 144, if applicable, is dependent upon 
adequate current public information with respect to the Company being 
available and, at the time that I may desire to make a sale pursuant to the 
Rule, the Company may neither wish nor be able to comply with such 
requirement.

    In consideration of the issuance of certificates for the shares to me, I 
hereby represent and warrant that I am acquiring such shares for my own 
account for investment, and that I will not sell, pledge, transfer or 
otherwise dispose of such shares in the absence of an effective registration 
statement covering the same, except as permitted by the provisions of Rule 
144, if applicable, or some other applicable exemption under the 1933 Act.  
In view of this representation and warranty, I agree that there may be 
affixed to the certificates for the shares to be issued to me, and to all 
certificates issued hereafter representing such shares (until in the opinion 
of counsel, which opinion must be reasonably satisfactory in form and 
substance to counsel for the Company, it is no longer necessary or required) 
a legend as follows:

    "The shares of common stock represented by this certificate have not
    been registered under the Securities Act of 1933, as amended (the
    "Act"), and were acquired by the registered holder, pursuant to a
    representation and warranty that such holder was acquiring such shares
    for his or her own account and for investment, with no intention to
    transfer or dispose of the same, in violation of the registration
    requirements of the Act.  These shares may not be sold, pledged,
    transferred or otherwise disposed of in the absence of an effective
    registration statement under the Act, or an opinion of counsel, which
    opinion is reasonably satisfactory to counsel to the Company, to the
    effect that registration is not required under the Act."

    I further agree that the Company may place a stop order with its Transfer
Agent, prohibiting the transfer of such shares, so long as the legend remains
on the certificates representing the shares.

                                  Very truly yours,


                                  ______________________________
                                  Optionee:
