                                                           [Extension Agreement]

                         DEVELOPMENT AGREEMENT ADDENDUM

        THIS DEVELOPMENT AGREEMENT ADDENDUM (the "Addendum") is entered into as
of May 1, 1998, between Starbucks Corporation, a Washington corporation
("Starbucks") and Host International, Inc., a Delaware corporation ("Licensee").

                                   RECITALS:

        WHEREAS, Licensee and Starbucks are parties to that certain development
agreement dated March 1994 (the "Development Agreement"); and

        WHEREAS, the parties have developed numerous airport and other locations
pursuant to the Development Agreement; and

        WHEREAS, the ownership rights in and to the trademarks, trade names,
service marks, logos, designs, emblems, trade dress and other indicia of origin
of Starbucks and all goodwill therewith in the United States of America
(collectively the "Trademarks") have been transferred from Starbucks to
Starbucks U.S. Brands Corporation, a California corporation ("Starbucks U.S.
Brands"); and

        WHEREAS, the parties desire to amend the Development Agreement as
provided herein;

        NOW THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, the parties agree as follows:

1. TRADEMARKS. Host hereby acknowledges that the ownership rights in and to the
Trademarks have been transferred from Starbucks to Starbucks U.S. Brands, and
Starbucks U.S. Brands has granted Starbucks a license to use and sublicense the
Trademarks. Host also agrees that all references in the Development Agreement,
as amended, regarding rights of ownership and all benefits of ownership and use
of the Trademarks are amended such that it is understood and agreed that such
rights and benefits shall run to Starbucks U.S. Brands, or its successors in
interest, as owner of the Trademarks.

2. TERM. Section 3 of the Development Agreement provides for a five-year term.
In addition, Section 3(b) of the Development Agreement provides that the Term
(as defined therein) "...will automatically renew for an additional period of
five (5) years, unless Starbucks or Licensee provide written notice to the other
party at least thirty (30) days prior to the expiration of the basic term."

The parties hereby agree that the Term is extended for the five-year option
period; therefore, the following words are hereby deleted from Section 3(b) of
the Development Agreement:

                ...unless Starbucks or Licensee provide written notice to the
                other party at least thirty (30) days prior to the expiration of
                the basic term.

3. MANAGEMENT. Licensee hereby agrees that, at all times during the term of the
Development Agreement:

        a. Licensee shall designate a Manager or Director of Brand
        Development/Starbucks who will serve as a primary point of contact and
        resource to Licensee's organization for operation and development of the
        Starbucks concepts. Following execution of this Addendum, the job
        description for such person shall be developed and mutually agreed to by
        Licensee and Starbucks.

        b. Licensee shall designate a manager, assistant manager or shift leader
        for each Starbucks unit. Following execution of this Addendum, Starbucks
        and Licensee shall jointly define the criteria for establishing which of
        the three choices (i.e., manager, assistant manager or shift leader) is
        appropriate for each unit based on volume considerations, complexity and
        size of the operation.

        c. at any Starbucks Licensed Location where Licensee operates more than
        one Starbucks unit, Licensee shall designate one of the store managers
        to oversee the management, operation and quality assurance of all the
        Starbucks units at Licensee's Location (e.g., at the airport, mall,
        etc...).

        d. Licensee shall designate at least two certified trainers per store.

4. ENTIRE AGREEMENT. Except as modified hereby, the Development Agreement (as
previously amended) remains in full force and effect.

        IN WITNESS WHEREOF, the parties have executed this Addendum as of the
day and year written below their signature.

                                                                    EXHIBIT 10.1

                            INDEMNIFICATION AGREEMENT

        This Indemnification Agreement (the "Agreement") is made as of December
__, 2000, by and between Xcyte Therapies, Inc., a Delaware corporation (the
"Company"), and ___________ (the "Indemnitee").

                                    RECITALS

        The Company and Indemnitee recognize the increasing difficulty in
obtaining liability insurance for directors, officers and key employees, the
significant increases in the cost of such insurance and the general reductions
in the coverage of such insurance. The Company and Indemnitee further recognize
the substantial increase in corporate litigation in general, subjecting
directors, officers and key employees to expensive litigation risks at the same
time as the availability and coverage of liability insurance has been severely
limited. Indemnitee does not regard the current protection available as adequate
under the present circumstances, and Indemnitee and agents of the Company may
not be willing to continue to serve as agents of the Company without additional
protection. The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, and to indemnify its directors,
officers and key employees so as to provide them with the maximum protection
permitted by law.

                                    AGREEMENT

        In consideration of the mutual promises made in this Agreement, and for
other good and valuable consideration, receipt of which is hereby acknowledged,
the Company and Indemnitee hereby agree as follows:

        1. INDEMNIFICATION.

                (a) THIRD PARTY PROCEEDINGS. The Company shall indemnify
Indemnitee if Indemnitee is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Company) by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action, suit or proceeding if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe Indemnitee's
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that Indemnitee did
not act in good faith and in a manner which Indemnitee

<PAGE>   2

reasonably believed to be in or not opposed to the best interests of the
Company, or, with respect to any criminal action or proceeding, that Indemnitee
had reasonable cause to believe that Indemnitee's conduct was unlawful.

                (b) PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. The Company
shall indemnify Indemnitee if Indemnitee was or is a party or is threatened to
be made a party to any threatened, pending or completed action or proceeding by
or in the right of the Company or any subsidiary of the Company to procure a
judgment in its favor by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) and, to the fullest extent
permitted by law, amounts paid in settlement (if such settlement is approved in
advance by the Company, which approval shall not be unreasonably withheld), in
each case to the extent actually and reasonably incurred by Indemnitee in
connection with the defense or settlement of such action or suit if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company and its stockholders, except
that no indemnification shall be made in respect of any claim, issue or matter
as to which Indemnitee shall have been finally adjudicated by court order or
judgment to be liable to the Company in the performance of Indemnitee's duty to
the Company and its stockholders unless and only to the extent that the court in
which such action or proceeding is or was pending shall determine upon
application that, in view of all the circumstances of the case, Indemnitee is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

                (c) MANDATORY PAYMENT OF EXPENSES. To the extent that Indemnitee
has been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 1(a) or Section 1(b) or the defense of any
claim, issue or matter therein, Indemnitee shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by Indemnitee in
connection therewith.

        2. NO EMPLOYMENT RIGHTS. Nothing contained in this Agreement is intended
to create in Indemnitee any right to continued employment.

        3. EXPENSES; INDEMNIFICATION PROCEDURE.

                (a) ADVANCEMENT OF EXPENSES. The Company shall advance all
expenses incurred by Indemnitee in connection with the investigation, defense,
settlement or appeal of any civil or criminal action, suit or proceeding
referred to in Section l(a) or Section 1(b) hereof (including amounts actually
paid in settlement of any such action, suit or proceeding). Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
by the Company as authorized hereby.

                (b) NOTICE/COOPERATION BY INDEMNITEE. Indemnitee shall, as a
condition precedent to his or her right to be indemnified under this Agreement,
give the Company notice in

                                      -2-
<PAGE>   3

writing as soon as practicable of any claim made against Indemnitee for which
indemnification will or could be sought under this Agreement. Notice to the
Company shall be directed to the Chief Executive Officer of the Company and
shall be given in accordance with the provisions of Section 12(d) below. In
addition, Indemnitee shall give the Company such information and cooperation as
it may reasonably require and as shall be within Indemnitee's power.

                (c) PROCEDURE. Any indemnification and advances provided for in
Section 1 and this Section 3 shall be made no later than thirty (30) days after
receipt of the written request of Indemnitee. If a claim under this Agreement,
under any statute, or under any provision of the Company's Certificate of
Incorporation or Bylaws providing for indemnification, is not paid in full by
the Company within thirty (30) days after a written request for payment thereof
has first been received by the Company, Indemnitee may, but need not, at any
time thereafter bring an action against the Company to recover the unpaid amount
of the claim and, subject to Section 11 of this Agreement, Indemnitee shall also
be entitled to be paid for the expenses (including attorneys' fees) of bringing
such action. It shall be a defense to any such action (other than an action
brought to enforce a claim for expenses incurred in connection with any action,
suit or proceeding in advance of its final disposition) that Indemnitee has not
met the standards of conduct which make it permissible under applicable law for
the Company to indemnify Indemnitee for the amount claimed, but the burden of
proving such defense shall be on the Company and Indemnitee shall be entitled to
receive interim payments of expenses pursuant to Section 3(a) unless and until
such defense may be finally adjudicated by court order or judgment from which no
further right of appeal exists. It is the parties' intention that if the Company
contests Indemnitee's right to indemnification, the question of Indemnitee's
right to indemnification shall be for the court to decide, and neither the
failure of the Company (including its Board of Directors, any committee or
subgroup of the Board of Directors, independent legal counsel, or its
stockholders) to have made a determination that indemnification of Indemnitee is
proper in the circumstances because Indemnitee has met the applicable standard
of conduct required by applicable law, nor an actual determination by the
Company (including its Board of Directors, any committee or subgroup of the
Board of Directors, independent legal counsel, or its stockholders) that
Indemnitee has not met such applicable standard of conduct, shall create a
presumption that Indemnitee has or has not met the applicable standard of
conduct.

                (d) NOTICE TO INSURERS. If, at the time of the receipt of a
notice of a claim pursuant to Section 3(b) hereof, the Company has director and
officer liability insurance in effect, the Company shall give prompt notice of
the commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

                (e) SELECTION OF COUNSEL. In the event the Company shall be
obligated under Section 3(a) hereof to pay the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the
defense of such proceeding, with counsel approved by Indemnitee, upon the
delivery to Indemnitee of written notice of its election so to do. After
delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel

                                      -3-
<PAGE>   4

by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same proceeding, provided that (i) Indemnitee shall have the
right to employ counsel in any such proceeding at Indemnitee's expense; and (ii)
if (A) the employment of counsel by Indemnitee has been previously authorized by
the Company, (B) Indemnitee shall have reasonably concluded that there may be a
conflict of interest between the Company and Indemnitee in the conduct of any
such defense or (C) the Company shall not, in fact, have employed counsel to
assume the defense of such proceeding, then the fees and expenses of
Indemnitee's counsel shall be at the expense of the Company.

        4. ADDITIONAL INDEMNIFICATION RIGHTS; NONEXCLUSIVITY.

                (a) SCOPE. Notwithstanding any other provision of this
Agreement, the Company hereby agrees to indemnify the Indemnitee to the fullest
extent permitted by law, notwithstanding that such indemnification is not
specifically authorized by the other provisions of this Agreement, the Company's
Certificate of Incorporation, the Company's Bylaws or by statute. In the event
of any change, after the date of this Agreement, in any applicable law, statute,
or rule which expands the right of a Delaware corporation to indemnify a member
of its board of directors or an officer, such changes shall be deemed to be
within the purview of Indemnitee's rights and the Company's obligations under
this Agreement. In the event of any change in any applicable law, statute or
rule which narrows the right of a Delaware corporation to indemnify a member of
its board of directors or an officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement shall have
no effect on this Agreement or the parties' rights and obligations hereunder.

                (b) NONEXCLUSIVITY. The indemnification provided by this
Agreement shall not be deemed exclusive of any rights to which Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of stockholders or disinterested members of the Company's
Board of Directors, the General Corporation Law of the State of Delaware, or
otherwise, both as to action in Indemnitee's official capacity and as to action
in another capacity while holding such office. The indemnification provided
under this Agreement shall continue as to Indemnitee for any action taken or not
taken while serving in an indemnified capacity even though he or she may have
ceased to serve in any such capacity at the time of any action, suit or other
covered proceeding.

        5. PARTIAL INDEMNIFICATION. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred in the investigation, defense, appeal or settlement of any civil or
criminal action, suit or proceeding, but not, however, for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion of
such expenses, judgments, fines or penalties to which Indemnitee is entitled.

        6. MUTUAL ACKNOWLEDGMENT. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or public policy may override applicable
state law and prohibit the Company from indemnifying its directors and officers
under this Agreement or otherwise.

                                      -4-
<PAGE>   5

For example, the Company and Indemnitee acknowledge that the Securities and
Exchange Commission (the "SEC") has taken the position that indemnification is
not permissible for liabilities arising under certain federal securities laws,
and federal legislation prohibits indemnification for certain ERISA violations.
Indemnitee understands and acknowledges that the Company has undertaken or may
be required in the future to undertake with the SEC to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

        7. OFFICER AND DIRECTOR LIABILITY INSURANCE. The Company shall, from
time to time, make the good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company but is an officer; or of the Company's key employees, if
Indemnitee is not an officer or director but is a key employee. Notwithstanding
the foregoing, the Company shall have no obligation to obtain or maintain such
insurance if the Company determines in good faith that such insurance is not
reasonably available, if the premium costs for such insurance are
disproportionate to the amount of coverage provided, if the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or if Indemnitee is covered by similar insurance maintained by a parent
or subsidiary of the Company.

        8. SEVERABILITY. Nothing in this Agreement is intended to require or
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law. The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. The provisions of this Agreement shall be severable as provided
in this Section 8. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

        9. EXCEPTIONS. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

                (a) CLAIMS INITIATED BY INDEMNITEE. To indemnify or advance
expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except with respect
to proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or

                                      -5-
<PAGE>   6

advancement of expenses may be provided by the Company in specific cases if the
Board of Directors finds it to be appropriate;

                (b) LACK OF GOOD FAITH. To indemnify Indemnitee for any expenses
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous;

                (c) INSURED CLAIMS. To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) to the
extent such expenses or liabilities have been paid directly to Indemnitee by an
insurance carrier under a policy of officers' and directors' liability insurance
maintained by the Company; or

                (d) CLAIMS UNDER SECTION 16(b). To indemnify Indemnitee for
expenses or the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        10. CONSTRUCTION OF CERTAIN PHRASES.

                (a) For purposes of this Agreement, references to the "Company"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, and employees
or agents, so that if Indemnitee is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if its separate
existence had continued.

                (b) For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee or agent of the Company
which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan, its participants, or
beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan, Indemnitee shall be deemed to have acted in a
manner "not opposed to the best interests of the Company" as referred to in this
Agreement.

        11. ATTORNEYS' FEES. In the event that any action is instituted by
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee

                                      -6-
<PAGE>   7

with respect to such action, unless as a part of such action, the court of
competent jurisdiction determines that each of the material assertions made by
Indemnitee as a basis for such action were not made in good faith or were
frivolous. In the event of an action instituted by or in the name of the Company
under this Agreement or to enforce or interpret any of the terms of this
Agreement, Indemnitee shall be entitled to be paid all court costs and expenses,
including attorneys' fees, incurred by Indemnitee in defense of such action
(including with respect to Indemnitee's counterclaims and cross-claims made in
such action), unless as a part of such action the court determines that each of
Indemnitee's material defenses to such action were made in bad faith or were
frivolous.

        12. MISCELLANEOUS.

                (a) GOVERNING LAW. This Agreement and all acts and transactions
pursuant hereto and the rights and obligations of the parties hereto shall be
governed, construed and interpreted in accordance with the laws of the State of
Delaware, without giving effect to principles of conflict of law.

                (b) ENTIRE AGREEMENT; ENFORCEMENT OF RIGHTS. This Agreement sets
forth the entire agreement and understanding of the parties relating to the
subject matter herein and merges all prior discussions between them. No
modification of or amendment to this Agreement, nor any waiver of any rights
under this Agreement, shall be effective unless in writing signed by the parties
to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

                (c) CONSTRUCTION. This Agreement is the result of negotiations
between and has been reviewed by each of the parties hereto and their respective
counsel, if any; accordingly, this Agreement shall be deemed to be the product
of all of the parties hereto, and no ambiguity shall be construed in favor of or
against any one of the parties hereto.

                (d) NOTICES. Any notice, demand or request required or permitted
to be given under this Agreement shall be in writing and shall be deemed
sufficient when delivered personally or sent by telegram or fax, or forty-eight
(48) hours after being deposited in the U.S. mail, as certified or registered
mail, with postage prepaid, and addressed to the party to be notified at such
party's address as set forth below or as subsequently modified by written
notice.

                (e) COUNTERPARTS. This Agreement may be executed in two or more
