         except for those  jurisdictions  in which  failure to be so licensed or
         qualified would not have a Material Adverse Effect.

                           (b) Authorization, Execution and Delivery. Subject to
         the  Stockholder  Approval  Requirement,  the execution and delivery of
         this  Agreement and each other  Transaction  Agreement to which it is a

         and  thereunder,  and the  consummation  by Issuer of the  transactions
         contemplated  hereby and  thereby  will have been duly  authorized  and

         Agreement constitutes, and each other Transaction Agreement to which it
         is a party will constitute,  a legal,  valid, and binding obligation of
         Issuer enforceable against Issuer in accordance with its terms.

     Issuer nor any  Subsidiary is in violation of any such Law or  Governmental
     Order,  except where the failure to so comply or any such  violation  could
     not reasonably be expected to have a Material Adverse Effect.

     the  respective  parties  thereto and is in full force and effect and, upon
     consummation of the  transactions  contemplated  hereby,  shall continue in

     Action been threatened,  against Issuer or any Subsidiary either based upon
     or  challenging  or  seeking to deny or  restrict  the use by Issuer or any
     Subsidiary  of  any  of  the  Owned   Intellectual   Property  or  Licensed
     Intellectual  Property or alleging that any services provided,  or products

     manufactured,  or sold in  violation  of any  Intellectual  Property of any
     Person.   To  the  best  knowledge  of  Issuer,  no  Person  is  using  any
     Intellectual Property that is confusingly similar to the Owned Intellectual
     Property or the Licensed  Intellectual  Property or that  infringe upon the
     Owned Intellectual  Property or the Licensed  Intellectual Property or upon
     the rights of Issuer or any  Subsidiary  therein,  thereto,  or thereunder.
     Neither  Issuer nor any Subsidiary has granted any license or sublicense or
     other  right  to any  other  Person  with  respect  to  any  of  the  Owned
     Intellectual   Property  or  the  Licensed   Intellectual   Property.   The
     consummation of the transactions contemplated hereby will not result in the
     termination or impairment of any of the Owned Intellectual  Property or the
     Licensed  Intellectual  Property.  To the  best  knowledge  of  Issuer,  no
     employee  of  Issuer  or  any  Subsidiary  has  violated  any   proprietary
     information  agreement,  employment agreement,  or similar Contract,  which
     such employee had with any previous employer,  or any Intellectual Property
     policy  of any such  employer,  or is a party  to any  Action  relating  to
     Intellectual Property.

          (p) Assets.  Issuer or a  Subsidiary  owns,  leases,  or has the legal
     right to use all of the  Material  Assets and,  with  respect to  Contracts
     forming a part of the Material Assets, Issuer or a Subsidiary is a party to
     and  enjoys  the  right to the  benefits  of such  Contracts.  Issuer  or a
     Subsidiary has good and  marketable  title to, or, in the case of leased or
     subleased, or licensed or sublicensed Material Assets, valid and subsisting
     leasehold interests in or licenses to, all of the Material Assets, free and
     clear of all Encumbrances, except for Permitted Encumbrances.

          (q) Customers and Suppliers.  No supplier to or customer of Issuer has
     terminated  or  substantially  altered,  or  has  notified  Issuer  of  any
     intention to  terminate  or  substantially  alter,  its  existing  business
     relationship  with Issuer,  except for any termination or alteration  which
     could not reasonably be expected to have a Material Adverse Effect.

          (r) Key  Employees.  To the best  knowledge  of Issuer,  no officer or
     senior  management,  technical,  or professional  employee of Issuer or any
     Subsidiary  (each  a  "Key  Employee")  intends  to  terminate  his  or her
     employment  relationship  with Issuer or any such  Subsidiary,  and neither
     Issuer nor any  Subsidiary  has any  present  intention  to  terminate  the
     employment  of  any  officer  or  management,  technical,  or  professional
     employee thereof.  Each director and Key Employee is under written contract
     to  Issuer  or the  relevant  Subsidiary  to  maintain  in  confidence  all
     confidential or proprietary  information acquired by such individual in the
     course of his or her employment therewith,  and to assign to Issuer or such
     Subsidiary all inventions made by such  individual  within the scope of his
     or her  employment  during  such  employment  and for a  reasonable  period
     thereafter.

          (s)  Certain  Interests.  Except as set forth in  Section  5(s) of the
     Disclosure  Schedule,  to the best  knowledge  of Issuer,  no  stockholder,
     director, officer, or Key Employee of Issuer or any Subsidiary, no relative
     or spouse (or relative of such spouse) who resides  with, or is a dependent
     of,  any such  stockholder,  director,  officer,  or Key  Employee,  and no
     Affiliate  of any such  Person:  (i) has any direct or  indirect  financial
     interest  in  any  competitor,  customer,  or  supplier  of  Issuer  or any
     Subsidiary;   provided,   however,   that  the   ownership  of   securities
     representing  no more than one percent of the  outstanding  voting power of
     any  competitor,  supplier,  or customer,  and which are also listed on any
     national   securities   exchange  or  traded   actively  in  the   national
     over-the-counter  market,  shall not be deemed to be a "financial interest"
     so long as the Person  owning such  securities  has no other  connection or
     relationship  with  such  competitor,  supplier  or  customer;  (ii)  owns,
     directly or  indirectly,  in whole or in part, or has any other interest in
     any tangible or intangible  property belonging to or used, held for use, or
     intended  to be used by Issuer or any  Subsidiary  or  forming a part of or
     used,  held for use, or intended to be used in connection  with,  necessary
     for, or otherwise  material to the conduct of, the business and  operations
     of Issuer or any Subsidiary;  or (iii) has outstanding any  indebtedness to
     Issuer  or any  Subsidiary.  Except  as set  forth in  Section  5(s) of the
     Disclosure Schedule, neither Issuer nor any Subsidiary has any Liability or
     any other obligation of any kind,  nature, or description  whatsoever to or
     on behalf of any stockholder,  director, officer, or Key Employee of Issuer
     or any Subsidiary,  or, to the best knowledge of Issuer, to any relative or
     spouse (or relative of such spouse) who resides with, or is a dependent of,
     any  such  stockholder,  director,  officer,  or  Key  Employee,  or to any
     Affiliate of any such Person;  except for Liabilities  relating to: (A) the
     payment  of  salary  for  services  rendered;   (B)  the  reimbursement  of
     reasonable and necessary  business expenses incurred on behalf of Issuer or
     such  Subsidiary;  and (C) the payment or grant of other standard  employee
     benefits  made  generally  available  to all  employees  of  Issuer or such
     Subsidiary  (including  stock  option  agreements   outstanding  under  any
     employee  stock option plan approved by the board of directors of Issuer or

          (t) Taxes. Issuer and each Subsidiary has timely filed each return and
     report in respect of Taxes required to be filed thereby (collectively,  the
     "Tax  Returns").  All  Taxes  required  to be  shown on any Tax  Return  or
     otherwise due from Issuer or any Subsidiary  have been timely paid. All Tax
     Returns  are true and  complete in all  material  respects.  No  adjustment
     relating to any Tax Return has been proposed  formally or informally by any
     Governmental  Authority  and,  to the best  knowledge  of Issuer,  no basis
     exists  for any such  adjustment.  There  are no  pending  or,  to the best
     knowledge of Issuer, threatened Actions for the assessment or collection of
     Taxes  against  Issuer  or any  Subsidiary  or any  other  Person  that was
     required  or  permitted  to be  included in the filing of a Tax Return with
     Issuer or any Subsidiary on a consolidated or combined basis.  There are no
     Tax liens on any properties or assets of Issuer or any  Subsidiary,  except
     for  Tax  liens  in  excess  of  $7,500  individually,  or  $15,000  in the
     aggregate.  Issuer is entitled to a valid tax loss carry-forward for United
     States  income  tax  purposes  of not less than  $2,254,000  as of the last
     audited Issuer financial statements,  which tax loss carry-forward will not
     expire  (to the  extent  not used) for at least  four  years  from the date
     hereof;   provided   that:  (i)  Issuer  has  not  utilized  any  tax  loss
     carry-forward since the date of Issuer's last audited financial statements;
     and (ii) neither  Issuer nor any Subsidiary has taken any action that could
     reasonably be expected to preclude  Issuer from utilizing any such tax loss
     carry-forward.

          (u) Environmental Matters.  Issuer and each Subsidiary is and has been
     in compliance  with all  applicable  Environmental  Laws;  has obtained all
     Environmental  Permits necessary,  appropriate,  or desirable in connection
     with the  ownership  of their  respective  properties  and  assets  and the
     conduct of their respective  businesses;  and is and has been in compliance
     with the  requirements  of all such  Environmental  Permits;  in each case,
     except  for any  failure  to so  comply,  or to so obtain an  Environmental
     Permit,  which could not reasonably be expected to have a Material  Adverse
     Effect.

                                       9
<PAGE>

          (v) Insurance.  All material assets,  properties,  and risks of Issuer
     and each Subsidiary are, and for the past three years have been, covered by
     valid and,  except for policies  that have expired under their terms in the
     ordinary  course,  currently  effective  insurance  policies  or binders of
     insurance  (including,  without  limitation,  general liability  insurance,
     property insurance, business interruption insurance, directors and officers
     insurance and workers'  compensation  insurance) issued in favor of Issuer,
     in each case with reputable insurance companies,  in such types and amounts
     and covering  such risks as are  consistent  with  customary  practices and
     standards of companies  engaged in  businesses  and  operations  similar to
     those of Issuer and each Subsidiary.

          (w)  Private  Offering;  NASD  Compliance.  Assuming  the  accuracy of
     Investor's  representations in Section 6, the offer,  issuance, and sale of
     the  Shares,  the  Initial  Warrants,   the  Initial  Warrant  Shares,  the
     Subsequent  Warrants,  and the  Subsequent  Warrant  Shares are and will be
     exempt from the  registration and prospectus  delivery  requirements of the
     Securities Act, and have been  registered or qualified,  or are exempt from
     registration  and  qualification,   under  the  registration,   permit,  or
     qualification  requirements of all applicable  state  securities  laws. The
     offering  and sale of the Shares and the Initial  Warrants  pursuant to the
     terms and conditions of this Agreement and the Initial Warrants Certificate
     do not  violate  the  National  Association  of  Securities  Dealers,  Inc.
     ("NASD") By-Laws or the marketplace  rules of the Nasdaq Stock Market,  and
     Issuer is in full compliance with the listing eligibility rules promulgated
     by the  Nasdaq  Stock  Market  and has not  received  any  oral or  written
     notification from NASD or any Governmental  Authority regarding any failure
     to comply with such listing eligibility criteria.

          (x)  Registration  Rights.  Except as set forth in Section 5(x) of the
     Disclosure  Schedule,  the Investor Rights  Agreement and the  registration
     rights  to  be  provided  to  the  investors  making  the   contemporaneous
     investment described in Section 12(b)(iv) of this Agreement, neither Issuer
     nor any  Subsidiary has granted to any Person any rights to cause Issuer or
     any such  Subsidiary to register  under the  Securities  Act, any shares of
     capital  stock of  Issuer  or any such  Subsidiary  now or  hereafter  held
     thereby, or to sell any such shares of capital stock in connection with any
     registration  under  the  Securities  Act,  undertaken  by  Issuer  or  any
     Subsidiary on its own behalf or on behalf of any other Person.

          (y) Full  Disclosure.  Set  forth in  Section  5(y) of the  Disclosure
     Schedule is a list of pending material transactions not otherwise disclosed
     in the Disclosure Schedule. To the best knowledge of Issuer, there exist no
     facts,  circumstances,  or  conditions,  that  have  resulted  in or  could
     reasonably  be  expected to result in a Material  Adverse  Effect and which
     have not been disclosed in this Agreement or the  Disclosure  Schedule.  No
     representation  or  warranty  of  Issuer  in this  Agreement  or any  other
     Transaction Agreement,  nor any statement or certificate furnished or to be
     furnished to Investor pursuant hereto or thereto, or in connection with the
     transactions  contemplated hereby or thereby,  contains or will contain any
     untrue  statement  of a  material  fact,  or omits or will  omit to state a
     material fact necessary to make the statements  contained herein or therein
     not misleading.

          (z) Brokers.  No broker,  finder,  or investment banker is entitled to

     behalf of Issuer.

     SECTION . Representations  and Warranties of Investor.  As an inducement to
Issuer to enter into this Agreement,  except as set forth in a writing delivered
by Investor prior to the date hereof, Investor hereby represents and warrants to
Issuer as follows:

          (a)  Organization  and  Authority.  Investor  is  a  corporation  duly
     organized,  validly  existing,  and in good standing  under the laws of the
     State of Maryland,  and has all necessary power and authority to enter into
     this Agreement and each other Transaction Agreement to which it is a party,
     to carry out its obligations  hereunder and  thereunder,  and to consummate
     the transactions contemplated hereby and thereby.

          (b) Authorization,  Execution and Delivery. The execution and delivery

     contemplated  hereby and thereby have been duly  authorized and approved by
     all requisite action on the part of Investor.  This Agreement has been, and
     at the Closing each other Transaction Agreement to which it is a party will
     have been,  duly  executed and  delivered by Investor,  and  (assuming  due
     authorization,  execution,  and  delivery  by Issuer and each  other  party
     thereto)  this  Agreement  constitutes,  and  at  the  Closing  each  other
     Transaction  Agreement  to which it is a party  will  constitute,  a legal,
     valid, and binding obligation of Investor  enforceable  against Investor in
     accordance with its terms.

          (c) No Conflict.  The  execution,  delivery,  and  performance of this
     Agreement  and each other  Transaction  Agreement to which it is a party by

     give  to  others  any  rights  of  termination,   amendment,  acceleration,
     suspension, revocation or cancellation of, or result in the creation of any
     Encumbrance on any of the assets or properties of Investor pursuant to, any
     Contract  to which  Investor  is a party or by which any of such  assets or
     properties is bound or affected.

<PAGE>

          (d) Governmental Consents and Approvals. The execution,  delivery, and
     performance of this Agreement and each other Transaction Agreement to which
     it is a party  by  Investor  do not  and  will  not  require  any  consent,
     approval,  authorization,  or other order of,  action by,  filing with,  or
     notification to, any Governmental Authority.

          (e)  Investment  Purpose,   Knowledge  and  Experience.   Investor  is
     acquiring the Shares and the Initial Warrants for its own account, not as a
     nominee or agent,  solely for the purpose of investment and not with a view
     to, or for offer or sale in  connection  with,  any  distribution  thereof.
     Investor  has such  knowledge  and  experience  in  financial  and business
     matters  that it is  capable  of  evaluating  the  merits  and risks of its
     purchase  of the  Shares  and the  Initial  Warrants,  is able to bear  the
     economic risk of such investment for an indefinite  period of time, and has
     sufficient  financial  resources  available to support the complete loss of
     its investment the Shares and the Initial Warrants.

     SECTION 7. Access to Information. From the date hereof until the earlier of
the  Closing  or the  termination  hereof in  accordance  with its  terms,  upon
reasonable  notice,  Issuer shall and shall cause its  Representatives  and each
Subsidiary and their respective Representatives:  (i) to afford Investor and its
Representatives reasonable access, during normal business hours, to the offices,
properties,  other facilities,  books, and records of Issuer and each Subsidiary
and to those of their respective Representatives who have any knowledge relating
to  Issuer  or  any  Subsidiary;  and  (ii)  to  furnish  to  Investor  and  its

authorizations,  consents, orders, and approvals of all Governmental Authorities
and officials that may be or become necessary for its execution and delivery of,
and the  performance  of its  obligations  pursuant to, this Agreement and shall

authorizations,  consents, orders, and approvals.  Issuer shall promptly give or
cause to be given such  notices  to third  parties  and use its best  efforts to
obtain  or  cause  to  be  obtained  such  third  party  consents  and  estoppel

steps as may be  necessary  to  obtain  all  such  material  proxies,  consents,
waivers, licenses, registrations, permits, authorizations,  rulings, orders, and

                  SECTION  11. No  Solicitation  or  Negotiation.  From the date
hereof until the earlier of the Closing or the termination  hereof in accordance
with its terms and except as expressly  provided in Section 11 of the Disclosure

facilitate  or encourage any effort or attempt by any other Person to seek to do

shall  prohibit  the  board  of  directors  of  Issuer  from:  (i)  considering,
negotiating,  and approving and  recommending to the  stockholders of Issuer the

its sole  discretion on  substantially  the same terms and  conditions set forth
herein;  (ii) complying with Rule 14e-2  promulgated under the Exchange Act with
regard to a tender or exchange  offer;  or (iii) after  receiving  the advice of
outside  counsel to the effect that the board of directors of Issuer is required

negotiating,  and approving and  recommending  to the  stockholders of Issuer an
unsolicited bona fide written  acquisition  proposal relating to the sale of the
entire company, which acquisition proposal was not received in violation of this
section. Issuer shall promptly notify Investor if any such proposal or offer, or
any inquiry or other  contact  with any Person with respect  thereto,  is or has
been made and shall,  in any such notice to  Investor,  indicate  in  reasonable
detail the  identity of the Person  making such  proposal,  offer,  inquiry,  or
contact and the terms and conditions of such proposal,  offer, inquiry, or other
contact.  Neither  Issuer nor any  Subsidiary  shall,  without the prior written

     circumstances,  or conditions that constitute or, with the giving of notice

     agreement.

          (iii) No  Actions;  Laws.  No  Action  shall  have been  commenced  or
     threatened  by or  before  any  Governmental  Authority  against  Issuer or

     materially and adversely affect the transactions  contemplated  hereby;  or
     (B) to result in a Material  Adverse Effect;  provided,  however,  that the

     (ii) any representation or warranty of Issuer contained herein was not true

     contained  herein was not true and complete in all material  respects  when
     made; or (ii)  Investor does not comply in all material  respects with each
     covenant or agreement contained herein to be performed or observed by it;

          (c) by  Investor  or Issuer if the  Closing  has not  occurred  within
     thirty (30) days after the date of Issuer's  annual  stockholders'  meeting
     with respect to fiscal year 2000, which is anticipated to occur on June 25,
     2001;  provided,  however,  that the  right  to  terminate  this  Agreement
     pursuant to this clause shall not be  available to any party whose  failure
     to fulfill  any  obligation  hereunder  is the cause of, or results in, the
     failure of the Closing to occur on or prior to such date;

          (d) by Investor  or Issuer if any  Governmental  Authority  issues any
     order, decree, or ruling or takes any other action restraining,  enjoining,
     or otherwise  prohibiting  the  transactions  contemplated  hereby and such
     order, decree, ruling, or other action becomes final and nonappealable; or

          (e) by the mutual written consent of Investor and Issuer.

     SECTION 14. Use of Proceeds.  Issuer shall use the proceeds  received  from

Schedule.

     SECTION  16.  Indemnification;  Contribution.  Indemnification.  Each party
hereto (in its  capacity  as  indemnitor  hereunder,  the  "Indemnitor"),  shall
indemnify  the other party  hereto,  each  Affiliate of such other  party,  each
successor and assign of each such Person, and each Representative of each of the
foregoing  (each  such  Person  in its  capacity  as  indemnitee  hereunder,  an
"Indemnitee"), with respect to, and hold each of them harmless from and against,
any and all Losses  resulting from,  arising out of, or relating to Indemnitor's
breach of any representation, warranty, covenant, or agreement thereof contained
in this Agreement or any other Transaction Agreement, and any action or omission
of Indemnitor in connection with the  performance of its obligations  under this
Agreement or any other Transaction Agreement.

                                       17
<PAGE>

          (b)  Contribution.  To the extent that the  undertakings of Indemnitor
     set forth in this section may be unenforceable, Indemnitor shall contribute
     the maximum amount that it is permitted to contribute  under applicable Law
     to the payment and satisfaction of all Losses incurred by any Indemnitee.

          (c) Loss  Notices.  If any  Indemnitee  determines  that any  facts or
     circumstances  have given or could reasonably be expected to give rise to a
     right of  indemnification  under this section,  such Indemnitee  shall give
     Indemnitor  notice (a "Loss Notice") of such facts or circumstances  within
     thirty  days of such  determination,  stating  the  amount of the Loss,  if
     known,  and method of  computation  thereof,  and  describing in reasonable
     detail the facts and circumstances  upon which such determination is based;
     provided that, if any such  determination is based, in whole or in part, on
     any  Action  brought  by or on behalf of any  third  party (a  "Third-Party
     Claim"),  such  Indemnitee  shall give  Indemnitor a Loss Notice in respect
     thereof within ten days of such  determination;  provided  further that any
     failure timely to provide a Loss Notice shall not release  Indemnitor  from
     any of its obligations under this section,  except to the extent Indemnitor
     is materially  prejudiced by such failure, and shall not relieve Indemnitor
     from any other  obligation or liability  that it may have to any Indemnitee
     otherwise than under this section.

          (d) Third-Party  Claims. If Indemnitor  acknowledges in writing within
     five  Business  Days after its receipt of any Loss  Notice  relating to any
     Third-Party  Claim  its  obligation  to  indemnify  and hold  harmless  any
     Indemnitee  under this section from and against any Losses  resulting  from
     such  Third-Party  Claim,  then Indemnitor  shall be entitled to assume and
     control  the defense of such  Third-Party  Claim at its expense and through
     counsel of its choice (which counsel shall be reasonably acceptable to such
     Indemnitee);  provided  that,  if there exists or is  reasonably  likely to
     exist a  conflict  of  interest  that would  make it  inappropriate  in the
     judgment of such  Indemnitee  for the same counsel to  represent  both such
     Indemnitee and Indemnitor, then such Indemnitee shall be entitled to retain
     its  own  counsel,   at  Indemnitor's  sole  cost  and  expense,   in  each
     jurisdiction  for which such Indemnitee  reasonably  determines  counsel is
     required. If Indemnitor is, directly or indirectly,  conducting the defense
     against any Third-Party  Claim,  Indemnitee shall cooperate with Indemnitor
     in such defense and make available to Indemnitor  all witnesses,  pertinent
     records,  materials,  and  information in such  Indemnitee's  possession or
     under its control relating thereto as is reasonably required by Indemnitor.
     If any  Indemnitee  is,  directly  or  indirectly,  conducting  the defense
     against  any  Third-Party  Claim,  Indemnitor  shall  cooperate  with  such
     Indemnitee  in such  defense  and make  available  to such  Indemnitee,  at
     Indemnitor's sole cost and expense, all such witnesses, records, materials,
     and  information in Indemnitor's  possession or under its control  relating
     thereto as is reasonably required by such Indemnitee.  Indemnitor shall not
     settle any  Third-Party  Claim  without  the prior  written  consent of the
     Indemnitee which delivered the Loss Notice in respect thereof.

                                       18

          (e) Other Rights and Remedies Not Affected. The indemnification rights
     of the parties  under this  section are  independent  of and in addition to
     such  rights and  remedies  as the  parties may have at law or in equity or
     otherwise  for any  misrepresentation,  breach of  warranty,  or failure to
     fulfill  any  agreement  or  covenant  hereunder  on the part of any  party
     hereto,  including,   without  limitation,   the  right  to  seek  specific
     performance,  rescission, or restitution,  none of which rights or remedies
     shall be affected or diminished hereby.

     SECTION 17. Miscellaneous. (a) Further Action. Issuer shall, promptly after
any request therefor by Investor and at Issuer's sole cost and expense,  take or
cause to be taken all  actions,  do or cause to be done all things,  and execute
and deliver or cause to be executed and  delivered all  documents,  instruments,
certificates, further assurances, or other papers, which Investor may reasonably
deem necessary,  appropriate, or desirable in connection with this Agreement and
the consummation of the transactions contemplated hereby.

                  (b) Survival of Certain  Covenants  and  Agreements.  Issuer's
covenants and  representations  and agreements  contained in Sections 5, 14, 15,
16, and 17 shall survive the Closing; and Issuer's covenants and representations
and agreements contained in Sections 5, 16, and 17 shall survive the termination
or expiration hereof.

                  (c) Expenses.  Except as otherwise  provided herein each party
hereto shall pay its own costs and expenses,  including, without limitation, all
fees and  disbursements  of  counsel,  incurred by or on behalf of such party in
connection  with  this  Agreement  and  the  consummation  of  the  transactions
contemplated hereby; provided, however, that, if a final and binding judgment is
obtained  by any  party  to this  Agreement  against  any  other  party  to this
Agreement  in  any  Designated  Action,  such  judgment  debtor  shall  pay  all
out-of-pocket costs and expenses (including, without limitation, reasonable fees
and disbursements of counsel, accountants, experts, and consultants) incurred by
such judgment  creditor in  connection  with or resulting  from such  Designated
Action.

                  (d) Notices.  Any notice,  request,  claim,  demand,  or other
communication  given or made  hereunder  by any party hereto shall be in writing
and shall be given or made by  delivery  in person,  or by  reputable  overnight
business  courier  service,  telecopy,  or registered or certified mail (postage
prepaid, return receipt requested) to the addressee at its address or telecopier
number set forth in Schedule II hereto (or to such other  address or  telecopier
number as such party may  hereafter  specify for such purpose by notice given in
accordance with this paragraph).  Any notice,  request,  claim, demand, or other
communication  given or made hereunder by telecopy shall be followed promptly by
a confirmation copy sent by reputable  overnight  business courier service.  Any
notice,  demand,  request, or other  communication  hereunder shall be effective
upon the earliest of: (i) the receipt thereof by the addressee; (ii) the deposit
thereof in the mails of the United States of America;  provided,  however,  that
the time period in which any response to any such notice,  demand,  request,  or
other  communication  is required to be given  shall  commence  from the date of
receipt thereof by the addressee as evidenced by the return receipt with respect
thereto;  (iii) the  rejection  or other  refusal  of  delivery  thereof  by the
addressee or any agent of the addressee; or (iv) the failure of delivery thereof
as a result of the addressee's  failure to properly give notice hereunder of any
change of its address or telecopier number.

     (e) Assignment.  Except as otherwise provided herein, no party hereto shall
assign its rights or delegate its  obligations  hereunder by operation of law or
otherwise  without each other party's express written consent (which consent may
be granted or withheld in such party's sole and absolute  discretion);  provided
that  Investor  may  assign  in  whole or in part its  rights  hereunder  to any
Affiliate  thereof  without the consent of Issuer;  and either  party hereto may
assign in whole or in part its rights hereunder to any Person that acquires more
than 50% of the outstanding voting securities or all or substantially all of the
assets  of  the  assigning  party  (whether  by  way of  merger  or  otherwise).
Notwithstanding  anything to the contrary  contained in this  Agreement,  Issuer
shall not  assign in whole or in part any of its rights or  delegate  any of its
obligations hereunder to any acquiror thereof that is a Major Hotel Operator (as
defined in Section 3(a) of the Development  Agreement) other than Investor until
the later to occur of : (A) the Closing Date; and (B) the expiration pursuant to
its terms of Issuer's  exclusivity  covenant in Section 3(b) of the  Development
Agreement.

     (f) Amendment;  Waiver. No amendment or restatement hereof or supplement or
other  modification  hereto shall be valid or effective  unless such  amendment,
restatement,  supplement, or other modification is in writing,  expressly refers
hereto, and is signed by each party hereto. No consent to, or waiver, discharge,
or  release  of,  any  term or  provision  or  breach  hereof  shall be valid or
effective  unless such  consent,  waiver,  discharge,  or release is in writing,
expressly refers hereto, and is signed by the party to be bound thereby,  and no
such consent, waiver,  discharge, or release shall constitute a consent, waiver,
discharge,  or release of any other term or provision  hereof or any  subsequent
breach  hereof,  whether  or not  similar in nature,  or a  subsequent  consent,
waiver,  discharge, or release of the same term, provision, or breach hereof. No
failure to exercise or delay in exercising any right, power, or remedy hereunder
by either party  hereto,  including  any failure to insist in any instance  upon
strict,  complete, or timely performance or observance by the other party hereto
of any term or provision  hereof or  obligation  hereunder,  shall  constitute a
consent, waiver,  discharge, or release of any such right, power, or remedy, and
no single or partial  exercise of any right,  power,  or remedy by either  party
hereto shall preclude any other or further exercise of any such right, power, or
remedy.

     (g) Entire Agreement.  This Agreement,  including all annexes,  appendices,
exhibits,  and schedules  hereto,  constitutes the entire agreement  between the
parties  hereto with respect to the subject  matter  hereof and  supersedes  all
prior or contemporaneous negotiations,  covenants, agreements,  representations,
warranties,  undertakings,  and understandings,  written or oral, and courses of
conduct and dealing  between the  parties  hereto,  with  respect to the subject
matter hereof.

                                       20

     (h)  Severability.  If any term or other provision  hereof is determined by
any court of competent jurisdiction to be invalid,  illegal, or unenforceable in
whole or in part by reason of any  applicable  Law or  public  policy,  and such
determination  becomes  final and  nonappealable,  such term or other  provision
shall  remain in full force and effect to the fullest  extent  permitted by Law,
and all other terms and provisions  hereof shall remain in full force and effect
in their entirety.

     (i) Successors and Assigns;  No Third-Party  Beneficiaries.  This Agreement
shall be binding upon and inure solely to the benefit of the parties  hereto and
their respective  successors and permitted assigns, and nothing herein,  whether
express or implied,  is intended  to or shall  confer upon any other  Person any
legal or equitable right,  power, or remedy of any kind,  nature, or description
whatsoever  under or by reason  hereof;  provided,  however,  that the terms and
provisions hereof relating to indemnification of any indemnitee not party hereto
shall inure to the benefit of such indemnitee.

     (j) Remedies.  (i) All rights, powers, and remedies hereunder of each party
hereto shall,  to the fullest  extent  permitted by law, be  cumulative  and not
alternative,  and in addition to all other rights,  powers, and remedies of such
party,  whether  specifically  granted hereunder or otherwise existing under any
Law,  and may be  exercised  from time to time and as often and in such order as
such party may deem necessary,  appropriate,  or desirable,  and the exercise or
the  beginning  of the  exercise  of any right,  power,  or remedy  shall not be
construed to be a waiver of the right to exercise at the same time or thereafter
any other right, power, or remedy.

     (ii) Issuer hereby  acknowledges  that irreparable  damage would occur, and
Investor's remedies at law would be inadequate,  if any term or provision hereof
was not  performed  or observed  strictly  in  accordance  herewith,  and hereby
unconditionally  and irrevocably  waives any defense that may be available to it
that  Investor's  remedies  at law are  adequate  or that its  injuries  are not
irreparable.  Investor may,  without  posting any bond or other  security and in
addition to any remedy  available to it at law, obtain  equitable  relief in the
form  of  specific  performance,   temporary  restraining  order,  temporary  or
permanent injunction,  or any other equitable remedy which may then be available
to it.

     (k) Governing Law. This  Agreement  shall be governed by, and construed and
enforced in accordance with, the laws of the State of California.

     (l) Waiver of Jury Trial.  Each party  hereto  hereby  unconditionally  and
irrevocably waives all right to trial by jury in any action, suit, or proceeding
(whether  based on contract,  tort, or otherwise)  based upon,  resulting  from,
arising out of, or relating to this  Agreement or any  transaction  or agreement
contemplated hereby.

     (m)   Jurisdiction;   Service  of  Process.   Each  party   hereto   hereby
unconditionally  and irrevocably  submits,  for itself and its property,  to the
exclusive  jurisdiction of the Designated Courts over any Designated Action. All
claims with respect to any Designated  Action shall be heard and determined in a
Designated Court. No party hereto shall commence any Designated Action except in
a Designated  Court. No party hereto shall,  and each party hereto hereby waives
any right it may have to:  (i) plead or make any  objection  to the venue of any
Designated  Court;  (ii)  plead or make any  claim  that any  Designated  Action
brought in any  Designated  Court has been  brought in an improper or  otherwise
inconvenient  forum;  (iii)  plead or make any claim that any  Designated  Court
lacks personal  jurisdiction  over it; or (iv) seek any punitive  damages in any
Designated  Action.  Any final Governmental Order in any Designated Action shall
be conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner  provided by law. The summons and  complaint or any other
process  in  any  Designated  Action  may be  served  by  mailing  to any of the

participated  equally in the  preparation  and  negotiation  of this  Agreement,
including all annexes,  appendices,  exhibits,  and schedules  hereto,  and each
party hereto hereby unconditionally and irrevocably waives to the fullest extent

counterparts and by the different parties hereto in separate counterparts,  each
of which when executed shall be deemed to be an original, and all of which taken
together shall  constitute one and the same agreement with the same effect as if

                                       33DEVELOPMENT AGREEMENT

                  DEVELOPMENT  AGREEMENT,   dated  as  of  June  ___,  2001  (as
hereafter amended,  supplemented,  or otherwise modified from time to time, this
"Agreement"), between GRILL CONCEPTS, INC., a corporation organized and existing
under the laws of the State of Delaware ("GCI"); and STARWOOD HOTELS AND RESORTS
WORLDWIDE,  INC., a  corporation  organized  and existing  under the laws of the
State of Maryland ("Starwood");

                              W I T N E S S E T H:

                  WHEREAS,  pursuant to the subscription agreement,  dated as of
May 16,  2001 (the  "Subscription  Agreement"),  between GCI and  Starwood,  GCI
issued to Starwood 666,667 shares of common stock of GCI, par value $0.00004 per
share (the "Common  Stock"),  and warrants to purchase  666,667 shares of Common
Stock;

                  WHEREAS,  GCI  is  principally  engaged  in  the  business  of
developing,  managing,  operating,  and licensing  restaurants under the "Grill"
(the "Grill"),  the "Daily Grill" (the "Daily"), and the "City Bar & Grill" (the
"City") trademarks and business concepts;

                  WHEREAS,  GCI and Starwood wish to consider jointly developing
Grill-,  Daily-, and City-branded  restaurants in certain hotels  (collectively,
the "Starwood  Properties") owned,  managed, or franchised by Starwood (any such
restaurant  developed in any Starwood Property,  a "GCI Concept Facility"),  all
upon the terms and subject to the conditions set forth herein; and

                  WHEREAS, it is a condition precedent to Starwood's willingness
to consummate the transactions  contemplated by the Subscription  Agreement that
GCI shall have executed and delivered this Agreement;

                  NOW,  THEREFORE,  in  consideration  of the  foregoing and the
representations,  warranties,  covenants,  and agreements set forth herein,  and
other good and  valuable  consideration,  the receipt and  adequacy of which are
hereby  acknowledged,  and  intending to be legally  bound  hereby,  the parties
hereto hereby covenant and agree as follows:

                  SECTION 1.  Certain Defined Terms.  Capitalized terms used and
not  otherwise  defined  in  the  body  hereof are used herein as defined in the
Subscription Agreement.

                  SECTION 2). Development Proposals;  Negotiation in Good Faith.
Either party hereto may at any time in its sole discretion  propose to develop a
new GCI Concept Facility in any Starwood  Property.  Upon the making of any such
proposal,  each  party  hereto  shall  negotiate  in good  faith  with a view to
agreeing on the terms and conditions applicable to such development; but neither
party hereto shall have any legal or binding  obligation  or commitment to enter
into any  agreement  with  respect to any such  proposed  development.  Whenever
Starwood  and GCI agree to develop a new GCI Concept  Facility  in any  Starwood
Property,  they shall,  among other  things,  enter into a management  agreement
which shall be negotiated on a  property-by-property  basis using, as a starting
point, the management agreement term sheet attached as Exhibit A hereto (each, a
"Management Agreement"),  in the case of any Grill- or Daily-branded restaurant,
or a license agreement which shall be negotiated on a property-by-property basis
using, as a starting point, the template  agreement attached as Exhibit B hereto
(each, a "License Agreement"), in the case of any City-branded restaurant.
<PAGE>

     SECTION  3.  Exclusivity.  a) GCI  shall  not,  and shall  not  permit  any
controlled  Affiliate  thereof  to,  develop,  manage,  operate,  or license any
Grill-,  Daily-,  or  City-branded  restaurant  in any  hotel or  resort  owned,
managed,  or  franchised  by any Person that owns the rights to be a licensor or
franchisor of a hotel brand name (a "Flag") whereby there are greater than fifty
(50)  hotels or resorts  operating  under such Flag (any such  Person,  a "Major
Hotel Operator");  provided that this restriction shall not apply to the Grill-,
Daily-  and  City-branded   restaurants  listed  on  Exhibit  C  hereto,   which
restaurants  GCI hereby  represents  to Starwood are the only Grill-,  Daily- or
City-branded  restaurants that GCI develops,  manages,  operates or licenses (or
with respect to which GCI is in the process of negotiating Management Agreements
or License Agreements) in any hotel or resort owned, managed, or franchised by a
Major Hotel  Operator  (other than  Starwood)  as of the date  hereof;  provided
further that this  restriction  shall not restrict GCI from  engaging in branded
operations with non-Major Hotel Operators.

     b) All of GCI's  covenants  under this Section 3, including  Sections 3(a),
3(b),  3(c) and  3(d),  shall  expire  and be of no  further  force or effect at
midnight on any anniversary of the Closing Date (each,  an "Anniversary  Date"),
if the  aggregate  number  of  GCI  Concept  Facilities  covered  by  Management
Agreements and/or License  Agreements  entered into during the period commencing
on the Closing Date and ending on such Anniversary  Date;  divided by the number
of full  calendar  years that have  elapsed  between the  Closing  Date and such
Anniversary  Date;  is less than  3.0.  Solely  by way of  illustration,  if the
aggregate  number of GCI Concept  Facilities  covered by  Management  Agreements
and/or  License  Agreements  entered into during the first  twelve-month  period
following the Closing Date is nine (9),  GCI's covenant under Section 3(a) shall
remain in effect until at least the fourth  anniversary  of the Closing Date (as
of which date it will expire if the aggregate  number of GCI Concept  Facilities
covered by Management  Agreements and/or License  Agreements entered into during
such four-year period is less than twelve (12)).

     c) Subject to the  provisions of Section 3(b) above,  GCI's  covenant under
Section 3(a) with respect to Daily-branded  restaurants only shall expire and be
of no  further  force or effect at  midnight  on any  Anniversary  Date,  if the
aggregate number of Daily-branded GCI Concept  Facilities  covered by Management
Agreements  entered  into during the period  commencing  on the Closing Date and
ending on such  Anniversary  Date;  divided by the number of full calendar years
that have elapsed  between the Closing Date and such  Anniversary  Date; is less
than  1.0.  Solely  by  way  of   illustration,   if  the  aggregate  number  of
Daily-branded GCI Concept  Facilities  covered by Management  Agreements entered
into during the first  twelve-month  period  following the Closing Date is three
(3),  and  provided  GCI's  covenant  has not  expired  pursuant to the terms of
Section 3(b),  GCI's covenant  under Section 3(a) with respect to  Daily-branded
restaurants shall remain in effect until at least the fourth  anniversary of the
Closing  Date  (as of which  date it will  expire  if the  aggregate  number  of
Daily-branded GCI Concept  Facilities  covered by Management  Agreements entered
into during such four-year period is less than four (4)).
<PAGE>

     d) Subject to the  provisions of Section 3(b) above,  GCI's  covenant under
Section 3(a) with respect to Grill-branded  restaurants only shall expire and be
of no  further  force or effect at  midnight  on the second  anniversary  of the
Closing  Date  or on  any  consecutive  two-year  anniversary  thereof,  if  the
aggregate number of Grill-branded GCI Concept  Facilities  covered by Management
Agreements  entered into during the two-year  period ending on such date is less
than  one  (1).  Solely  by way of  illustration,  if the  aggregate  number  of
Grill-branded GCI Concept  Facilities  covered by Management  Agreements entered
into during the first twelve-month period following the Closing Date is two (2),
and provided  GCI's  covenant  has not expired  pursuant to the terms of Section
3(b),   GCI's  covenant  under  Section  3(a)  with  respect  to   Grill-branded
restaurants  shall remain in effect until at least the sixth  anniversary of the
Closing  Date  (as of which  date it will  expire  if the  aggregate  number  of
Grill-branded GCI Concept  Facilities  covered by Management  Agreements entered
into during such six-year period is less than three (3)).

     SECTION 4.  Development  Warrants.  GCI shall issue to  Starwood,  promptly
after  the date as of which  the  aggregate  number  of GCI  Concept  Facilities
covered by Management  Agreements and/or License  Agreements  entered into on or
after  the  date  hereof  reaches  five,  ten,  fifteen,  and  twenty  (each,  a
"Development  Threshold Date"), a warrant  substantially in the form attached as
Exhibit D hereto (each, a "Development  Warrant") to purchase a number of shares
of Common Stock  representing,  four percent (4%) of the then outstanding shares
of Capital  Stock of GCI (for  purposes  of this  Agreement,  the term  "Capital
Stock"  shall refer to the  aggregate of the then  outstanding  shares of Common
Stock and the then outstanding  shares of any class or series of preferred stock
of GCI).

     (a) If the Fair  Market  Value  of the  Common  Stock as of the  applicable
Development  Threshold  Date is greater than the Fair Market Value of the Common
Stock as of the Closing Date (the "Closing Date Share Price"),  the  Development
Warrants  will have an  exercise  price  equal to the  greater  of  seventy-five
percent (75%) of the Fair Market Value of the Common Stock as of the  applicable
Development Threshold Date; and the Closing Date Share Price; or

     (b) If the Fair  Market  Value  of the  Common  Stock as of the  applicable
Development  Threshold  Date is less than the  Closing  Date  Share  Price,  the
Development  Warrants will have an exercise price equal to the Fair Market Value
of the Common Stock as of the applicable Development Threshold Date.

For the avoidance of doubt, the Development  Threshold Date shall be the date of
the opening to the public of the relevant GCI Concept  Facility  that  triggered
GCI's obligation to issue the Development Warrants.

                  SECTION  5. Incentive  Warrants.  (a)  If,  as of the  date of
execution of any Management  Agreement or License Agreement covering any new GCI
Concept Facility (the "Initial Incentive  Threshold Date"), the aggregate number
of GCI  Concept  Facilities  covered by  Management  Agreements  and/or  License
Agreements  entered  into on or  after  the  date  hereof  (the  "Aggregate  New
Facilities") represents more than thirty-five percent (35%) of the then existing
Grill-,  Daily-,  or  City-branded  restaurants  (including all such GCI Concept
Facilities) (the "Incentive Threshold"),  GCI shall issue to Starwood,  promptly
after the Initial Incentive Threshold Date, a warrant  substantially in the form
attached  as  Exhibit D hereto to  purchase  a number of shares of Common  Stock
representing,   0.75  percent  (three-quarters  of  one  percent)  of  the  then
outstanding  shares  of  Capital  Stock of GCI (an  "Incentive  Warrant")  at an
exercise  price in each case equal to the Fair Market  Value of the Common Stock
on the Initial Incentive Threshold Date.
<PAGE>

                  (b)  (i)  If,  as of the  first  anniversary  of  the  Initial
Incentive Threshold Date (the "First Incentive Anniversary Date"), the Aggregate
New  Facilities  exceed the  Incentive  Threshold,  GCI shall issue to Starwood,
promptly thereafter,  an additional Incentive Warrant at an exercise price equal
to the Fair Market Value of the Common Stock on the First Incentive  Anniversary
Date to purchase a number of shares of Common  Stock  representing  0.75 percent
(three-quarters  of one percent) of the then outstanding shares of Capital Stock
of GCI, and GCI shall issue to Starwood an additional  Incentive Warrant on each
subsequent  anniversary of the Initial Incentive  Threshold Date (at an exercise
price in each case equal to the Fair Market  Value of the Common Stock as of the
applicable  anniversary  thereof) to purchase a number of shares of Common Stock
representing  0.75  percent   (three-quarters   of  one  percent)  of  the  then
outstanding shares of Capital Stock of GCI until the Aggregate New Facilities do
not exceed the Incentive Threshold as of any such anniversary date; and (ii) if,
as of  the  First  Incentive  Anniversary  Date  or any  subsequent  anniversary
thereof, the Aggregate New Facilities do not exceed the Incentive Threshold, GCI
shall not be  obligated  to issue to Starwood an  additional  Incentive  Warrant
unless  and until the  Aggregate  New  Facilities  again  exceed  the  Incentive
Threshold  as of the date of  execution  of a  Management  Agreement  or License
Agreement covering a new GCI Concept Facility (a "Subsequent Incentive Threshold
Date"). In such event, GCI shall be obligated to issue to Starwood an additional
Incentive Warrant promptly thereafter and on each subsequent  anniversary of the
Subsequent  Incentive Threshold Date (at an exercise price in each case equal to
the  Fair  Market  Value of the  Common  Stock  as of the  Subsequent  Incentive
Threshold  Date or the applicable  anniversary  thereof) to purchase a number of
shares of Common Stock representing 0.75 percent (three-quarters of one percent)
of the then  outstanding  shares of Capital Stock of GCI until the Aggregate New
Facilities  do not exceed the  Incentive  Threshold  as of any such  anniversary
date. In such event,  GCI's  obligation to issue additional  Incentive  Warrants
will be suspended until the Aggregate New Facilities  again exceed the Incentive
Threshold. The provisions of this Section 5(b) shall apply iteratively until the
expiration or termination of this Agreement.

                  SECTION 6). Account  Management.  Promptly after the execution
and delivery of the first Management  Agreement or License Agreement  hereunder,
GCI shall assign one of its account  managers to Starwood's GCI Concept Facility
development  team. The specific terms of such assignment  shall be negotiated by
the  parties in good  faith,  with the  understanding  that as the number of GCI
Concept Facilities increases it will become a full-time position.

     SECTION 7).  Miscellaneous.  The terms and provisions set forth in Sections
16 and 17 of the  Subscription  Agreement are  incorporated in this Agreement by
reference and made a part hereof mutatis mutandis.
