                           W I T N E S S E T H:

     WHEREAS, all capitalized terms used herein not otherwise defined shall have
the same meanings as set forth in Appendix A to the Participation Agreement,
dated as of the date hereof, among MiniMed Development Corp., as Construction
Agent and Lessee (the "Guaranteed Subsidiary"), the Parent Guarantor and certain
of its Subsidiaries, First Security Bank, National Association, not in its

the Revolving Credit Lenders, ING Baring Furman Selz LLC, as Syndication Agent,
and ING (U.S.) Capital LLC, as Agent and as Collateral Agent (the "Participation

     WHEREAS, the Parent Guarantor wishes to induce the Lessor to enter into the
Construction Agency Agreement and the Master Lease with the Guaranteed
Subsidiary (the Construction Agency Agreement and the Master Lease, as each of
them may be amended, modified, supplemented, or extended from time to time, are
collectively referred to hereinafter as the "Guaranteed Agreements"); and

     WHEREAS, the Parent Guarantor is the owner of one hundred percent (100%) of
the issued and outstanding capital stock of the Guaranteed Subsidiary, and the
consummation of the Guaranteed Agreements will inure to the benefit of the
Parent Guarantor, directly or indirectly; and

     WHEREAS, the Lessor is unwilling to enter into the Guaranteed Agreements
with the Guaranteed Subsidiary unless the Parent Guarantor enters into this
Guaranty.

     NOW, THEREFORE, in order to induce the Lessor to enter into the Guaranteed
Agreements and to consummate the transactions contemplated thereby, the Parent
Guarantor hereby agrees as follows:

   2

1. Guaranty.

(a) The Parent Guarantor unconditionally and irrevocably guarantees to the
Lessor the due and punctual performance of and compliance by the Guaranteed
Subsidiary with all

   3



obligations, covenants, warranties, undertakings and conditions of the
Guaranteed Subsidiary contained in or arising under the Guaranteed Agreements,
including, but not limited to, the full and punctual payment by the Guaranteed
Subsidiary, when due, whether at the stated due date, by acceleration or
otherwise, of any and all rent and other obligations, liabilities, indebtedness
and other amounts of every kind payable by the Guaranteed Subsidiary under or
pursuant to the Guaranteed Agreements, all amounts in respect of the indemnities
provided by the Guaranteed Subsidiary under the Guaranteed Agreements, and all
damages (whether provided for in the Guaranteed Agreements or otherwise
permitted by law) in respect of any failure or refusal by the Guaranteed
Subsidiary to make any such payment or to perform such obligation, howsoever
created, arising or evidenced, voluntary or involuntary, whether direct or
indirect, absolute or contingent, now or hereafter existing or owing to the
Lessor (all the foregoing obligations and undertakings are collectively referred
to hereinafter as the "Obligations").

(b) This Guaranty is an absolute and unconditional guaranty of performance and
payment when due of all obligations to be performed and all amounts to be paid
by the Guaranteed Subsidiary under the Guaranteed Agreements, and not of
collection of any indebtedness contained in or arising under the Guaranteed
Agreements. This Guaranty is in no way conditioned upon any attempt to collect
from the Guaranteed Subsidiary or upon any other event or contingency, and shall
be binding upon and enforceable against the Parent Guarantor without regard to
the validity or enforceability of the Guaranteed Agreements or of any term
thereof. If for any reason the Guaranteed Subsidiary shall fail or be unable
duly and punctually to pay any such amount when due under the Guaranteed
Agreements, the Parent Guarantor will forthwith pay, if not already paid by the
Guaranteed Subsidiary, the same immediately upon demand.

(c) In case either of the Guaranteed Agreements shall be terminated as a result
of the rejection thereof by any trustee, receiver or liquidating agent of the
Guaranteed Subsidiary or any of its properties in any bankruptcy, insolvency,
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar proceeding, the Parent Guarantor's obligations hereunder shall
continue to the same extent as if such agreement had not been so rejected. The
Parent Guarantor agrees that this Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time payment to the Lessor of the
Obligations or any part thereof is rescinded or must otherwise be returned by
the Lessor upon the insolvency, bankruptcy or reorganization of the Guaranteed
Subsidiary, or otherwise, as though such payment to the Lessor had not been
made.

(d) The Parent Guarantor shall pay all reasonable costs, expenses and damages
incurred (including, without limitation, attorneys' fees and disbursements) in
connection with the enforcement of (i) the Obligations to the extent that such
costs, expenses and damages are not paid by the Guaranteed Subsidiary and (ii)
the obligations of the Parent Guarantor under this Guaranty.
   4
2. Guaranty Continuing and Unlimited. The obligations of the Parent Guarantor
hereunder shall be continuing and unlimited, shall not be subject to any
counterclaim, set-off, deduction or defense (other than payment or performance)
based upon any claim the Parent Guarantor may have against the Lessor or the
Guaranteed Subsidiary or any other Person, and shall remain in full force and
effect without regard to, and shall not be released, discharged or in any way
affected by any circumstance or condition (whether or not the Parent Guarantor
shall have any knowledge or notice thereof) whatsoever which might constitute a
legal or equitable discharge or defense including, but not limited to (a) any
express or implied amendment or modification of or supplement to the Guaranteed
Agreements or any other agreement referred to in either thereof, or any other
instrument applicable to the Guaranteed Subsidiary or to the Obligations, or any
part thereof, or any assignment or transfer of any thereof; (b) any failure on
the part of the Guaranteed Subsidiary to perform or comply with any term of the
Guaranteed Agreements or any failure of any other Person to perform or comply
with any term of the Guaranteed Agreements, or any other agreement as aforesaid;
(c) any waiver, consent, change, extension, indulgence or other action or any
action or inaction under or in respect of the Guaranteed Agreements, or any
other agreement as aforesaid, or this Guaranty, whether or not the Lessor, the
Guaranteed Subsidiary or the Parent Guarantor has notice or knowledge of any of
the foregoing; (d) any bankruptcy, insolvency, reorganization, arrangement,
readjustment, composition, liquidation or similar proceeding with respect to the
Parent Guarantor or the Guaranteed Subsidiary, or their respective properties or
their creditors, or any action taken by any trustee or receiver or by any court
in any such proceeding ; (e) any furnishing or acceptance of additional security
or any release of any security, or the failure to perfect any Lien against, any
security for the Obligations or any action, or the absence of any action, by the
Collateral Agent, any Secured Party or the Lessor in respect of any such Lien or
security; (f) any limitation on the liability or Obligations of the Guaranteed
Subsidiary under the Guaranteed Agreements (other than any limitation expressly
provided for therein) or any termination, cancellation, frustration, invalidity
or unenforceability, in whole or in part, of the Guaranteed Agreements, or any
term of any thereof (including, without limitation, to the extent a court of
competent jurisdiction fails to give full effect to the intent of the parties to
the Master Lease set forth in Section 4 of the Master Lease, (i) any rejection
of the Master Lease by the Lessee or any trustee of the Lessee in any bankruptcy
proceeding filed by or against the Lessee and any limitation on damages which
may be recovered by the Lessor as a result of any such rejection or other
termination of the Master Lease in any such bankruptcy proceeding, and (ii) any
legal or equitable defense which the Lessee may assert against Lessor or its
rights and remedies under the Master Lease); (g) any lien, charge or encumbrance
on or affecting the Parent Guarantor's or the Guaranteed Subsidiary's respective
assets and properties; (h) any act, omission or breach on the part of the Lessor
under the Guaranteed Agreements, or any other agreement at any time existing
between the Lessor and the Guaranteed Subsidiary or any other law, governmental
regulation or other agreement applicable to the Lessor or any Obligation; (i)
any claim as a result of any other dealings among the Lessor, the Parent
Guarantor or the Guaranteed Subsidiary or any of them; (j) the assignment of the
Guaranteed Agreements by the Lessor to any other Person, or the assignment of
this Guaranty by the Lessor to any Person permitted under
   5

the Parent Guarantor's Consent; or (k) any change in the name of the Lessor, the
Guaranteed Subsidiary or any other Person referred to herein.

     The unconditional obligations of the Parent Guarantor set forth herein
constitute the full recourse obligations of the Parent Guarantor enforceable
against it to the full extent of all of its present and future income, assets
and properties.

3. Waiver. The Parent Guarantor unconditionally waives: (a) notice of any of the
matters referred to in Section 2 hereof; (b) all notices which may be required
by statute, rule of law or otherwise to preserve any rights against the Parent
Guarantor hereunder, including, without limitation, notice of the acceptance of
this Guaranty, or the creation, renewal, extension, modification or accrual of
the Obligations or notice of any other matters relating thereto, any
presentment, demand, notice of dishonor, protest, nonpayment of any damages or
other amounts payable under the Guaranteed Agreements; (c) any requirement for
the enforcement, assertion or exercise of any right, remedy, power or privilege
under or in respect of the Guaranteed Agreements, including, without limitation,
diligence in collection or protection of or realization upon the Obligations or
any part thereof or any collateral therefor; (d) any requirement of diligence;
(e) any requirement to mitigate the damages resulting from a default by the
Guaranteed Subsidiary under the Guaranteed Agreements; (f) the occurrence of
every other condition precedent to which the Parent Guarantor or the Guaranteed
Subsidiary may otherwise be entitled; and (g) the right to require the Lessor to
proceed against the Guaranteed Subsidiary or any other Person liable on the
Obligations, to proceed against or exhaust any security held from the Guaranteed
Subsidiary or any other Person, or to pursue any other remedy in the Lessor's
power whatsoever, and the Parent Guarantor waives the right to have the property
of the Guaranteed Subsidiary first applied to the discharge of the Obligations.

     The Lessor may, at its election, exercise any right or remedy it may have
against the Guaranteed Subsidiary or any security held by the Lessor, including,
without limitation, the right to foreclose upon any such security by judicial or
nonjudicial sale, without affecting or impairing in any way the liability of the
Parent Guarantor hereunder, except to the extent the Obligations have been paid,
and the Parent Guarantor waives any defense arising out of the absence,
impairment or loss of any right of reimbursement, contribution or subrogation or
any other right or remedy of the Parent Guarantor against the Guaranteed
Subsidiary or any such security, whether resulting from such election by the
Lessor or otherwise. The Parent Guarantor understands that the liability of the
Guaranteed Subsidiary to the Lessor for the Obligations may be secured by real
property and that the Parent Guarantor shall be liable for the full amount of
its liability hereunder notwithstanding foreclosure on such real property by
trustee sale or any other reason impairing the Parent Guarantor's right to
proceed against the Guaranteed Subsidiary. The Parent Guarantor waives any
defense arising by reason of any disability or other defense of the Guaranteed
Subsidiary or by reason of the cessation from any cause whatsoever of the
liability, either in whole or in part, of the Guaranteed Subsidiary to the
Lessor for the Obligations and all rights and defenses that the Parent Guarantor
may have because the Guaranteed Subsidiary's Obligations are secured by real
property. The Parent Guarantor
   6

hereby waives, to the fullest extent permitted by law, all rights and benefits
under section 2809 of the California Civil Code purporting to reduce a Parent
Guarantor's obligations in proportion to the principal obligation, all rights
and benefits under section 580a of the California Code of Civil Procedure
governing determination of fair market value following the exercise of power of
sale, all rights and benefits under section 580b of the California Code of Civil
Procedure stating that no deficiency may be recovered on a real property
purchase money obligation and all rights and benefits under section 580d of the
California Code of Civil Procedure stating that no deficiency may be recovered
on a note secured by a deed of trust on real property in case such real property
is sold under the power of sale contained in such deed of trust, and all rights
and benefits under section 726 of the California Code of Civil Procedure and any
and all similar laws now in effect or hereafter enacted in the State of
California regarding the procedures to be followed by a creditor with real
property security and/or limiting the right of such a creditor to a deficiency
judgment, including, without limitation, the California law now in effect
stating that the Lessor must first proceed against any real property collateral
before commencing an action to collect the Obligations, if such sections, or any
of them, have any application hereto or any application to the Parent Guarantor.
Accordingly, the Parent Guarantor waives all rights and defenses that the Parent
Guarantor may have because the Obligations are secured by real property. This
means, among other things: (i) the Lessor may collect from the Parent Guarantor
without first foreclosing on any real or personal property collateral pledged by
the Guaranteed Subsidiary; and (ii) if the Lessor forecloses on any real
property collateral pledged by the Guaranteed Subsidiary: (A) the amount of the
debt may be reduced only by the price for which that collateral is sold at the
foreclosure sale, even if the collateral is worth more than the sale price, and
(B) the Lessor may collect from the Parent Guarantor even if the Lessor, by
foreclosing on the real property collateral, has destroyed any right the Parent
Guarantor may have to collect from the Guaranteed Subsidiary. This is an
unconditional and irrevocable waiver of any rights and defenses the Parent
Guarantor may have because the Obligations are secured by real property. These
rights and defenses include, but are not limited to, any rights or defenses
based upon section 580a, 580b, 580d or 726 of the California Code of Civil
Procedure. The Parent Guarantor expressly waives any and all benefits under the
California Civil Code Sections 2787 to 2855 inclusive.

     The Parent Guarantor understands that the Lessor's exercise of certain
rights and remedies contained in the Guaranteed Agreements may affect or
eliminate the Parent Guarantor's rights of subrogation against the Guaranteed
Subsidiary and that the Parent Guarantor may therefore incur partially or
totally nonreimbursable liability hereunder; nevertheless, the Parent Guarantor
hereby authorizes and empowers the Lessor, its successors, endorsees and/or
assignees, to exercise in its or their sole discretion, any rights and remedies,
or any combination thereof, which may then be available, it being the purpose
and intent of the Parent Guarantor that its obligations hereunder shall be
absolute, independent and unconditional under any and all circumstances.
Accordingly, the Parent Guarantor waives all rights and defenses arising out of
an election of remedies by the Lessor, even though the election of remedies,
such as non-judicial foreclosure with respect to security for the Obligations,
has destroyed or

  omitted portions.

impaired the Parent Guarantor's rights of subrogation and reimbursement against
the principal by operation of Section 580d of the California Code of Civil
Procedure or otherwise.

     The Parent Guarantor assumes the responsibility for being and keeping
informed of the financial condition of the Guaranteed Subsidiary and of all
other circumstances bearing upon the risk of nonpayment of the Obligations and
agrees that the Lessor shall not have any duty to advise the Parent Guarantor of
information regarding any condition or circumstance or any change in such
condition or circumstance. The Parent Guarantor acknowledges that the Lessor has
not made any representation to the Parent Guarantor concerning the financial
condition of the Guaranteed Subsidiary.

4. Benefits of Guaranty. The provisions of this Guaranty are for the benefit of
the Lessor and its assigns, transferees, endorsees and successors, and nothing
contained herein shall impair, as between the Lessor and its assigns,
transferees, endorsees and successors, the Parent Guarantor and the Guaranteed
Subsidiary, the obligations of the Guaranteed Subsidiary under the Guaranteed
Agreements. In the event all or any part of the Obligations are transferred,
endorsed or assigned by the Lessor as permitted in the Guaranteed Agreements,
any reference to the "Lessor" herein shall be deemed to refer equally to such
Person or Persons.

5. Representations and Warranties of the Parent Guarantor. The Parent Guarantor
represents and warrants to the Lessor that:

(a) Corporate Existence. The Parent Guarantor (i) is duly organized, validly
existing and in good standing under the laws of the State of Delaware, (ii) has

Parent Guarantor), and no authorization of, notice to, or other act by any
governmental authority, agency or instrumentality is required in connection with
the execution, delivery, performance, validity or enforceability of this
Guaranty. This Guaranty has been duly executed and delivered on behalf of the
Parent Guarantor, and this Guaranty constitutes a legal, valid and binding
obligation of the Parent Guarantor, enforceable against the Parent Guarantor in
accordance with its terms, except as such enforceability may be limited by
bankruptcy and other similar laws affecting the rights of creditors generally or
by general principles of equity.
   8
(c) No Legal Bar. The execution, delivery and performance by the Parent
Guarantor of this Guaranty will not violate any provision of any existing Law or
regulation applicable to the Parent Guarantor or of any award, order or decree
applicable to the Parent Guarantor of any court, arbitrator or governmental
authority, or of the Certificate of Incorporation or By-Laws of the Parent
Guarantor, or of any security issued by the Parent Guarantor or of any mortgage,

Parent Guarantor or any property or rights of the Parent Guarantor which
questions the enforceability of this Guaranty or which as of the date hereof
could reasonably be expected to exceed $1,000,000, or after the date hereof
could reasonably be expected to have a Material Adverse Effect.

(e) ERISA. Except as disclosed on Schedule 5(e):

     (i)   neither the Parent Guarantor, its Subsidiaries nor any ERISA

     (ii)  each Plan maintained by the Parent Guarantor or any of its

     operation, in compliance with all applicable laws, and neither the Parent
     Guarantor nor any of its Subsidiaries is subject to any tax or penalty with

     Plan which is subject to Title IV of ERISA, each ERISA Affiliate have made
     full and timely payment of all amounts (A) required to be contributed under
     the terms of each Plan and applicable law, and (B) required to be paid as
   9

     expenses (including PBGC or other premiums) of each Plan, and no Plan
     subject to Title IV of ERISA has an "amount of unfunded benefit
     liabilities" (as defined in Section 4001(a)(18) of ERISA), determined as if
     such Plan terminated on any date on which this representation or warranty
     is made or deemed to be made; and

its Subsidiaries in writing to the Lessor, the Agent, the Collateral Agent, the

Neither this Guaranty nor any document or statement furnished to the Lessor, the
Agent, the Collateral Agent, the Lenders, the Certificateholders or the
Revolving Credit Lenders by or on behalf of the Parent Guarantor or any of its

excepted, and are free and clear of known defects except for defects which do
not substantially interfere with the use thereof in the conduct of normal
operations.

(q) Trade Relations. As of the Effective Date, there exists no actual or, to the
best of Parent Guarantor's knowledge, threatened termination, cancellation or
limitation of, or any modification or change in, the business relationship of
the Parent Guarantor or any of its Subsidiaries with any material customer or

Adverse Effect.

(u) Year 2000 Compliance. The software and the hardware operated by the

adaptations and replacements of software and hardware required to achieve full
Y2K Compliance will be completed on or before September 30, 1999, except where a

Effect.

6. Payments. Each payment by the Parent Guarantor to the Lessor under this
Guaranty shall be made by transferring the amount thereof to the Lessor or to an
account designated by the Lessor in immediately available funds without set-off
or counterclaim. The making of any payments by the Parent Guarantor hereunder
shall not constitute a waiver of any rights not waived pursuant hereto that the

7. Parties. This Guaranty shall inure to the benefit of the Lessor and its
successors, assigns or transferees, and shall be binding upon the Parent

any of its duties under this Guaranty without the prior written consent of the
Lessor and the Collateral Agent. The Lessor and its successors, assigns and
transferees may assign its or their rights and benefits under this Guaranty as
provided in the Parent Guarantor Consent.

8. Remedies. The Parent Guarantor stipulates that the remedies at law in respect
of any default or threatened default by the Parent Guarantor in the performance
of or compliance with any of the terms of this Guaranty are not and will not be
adequate, and that any of such terms may be specifically enforced by a decree
for specific performance or by an injunction against violation of any such terms
or otherwise.

9. Rights to Deal with the Guaranteed Subsidiary. At any time and from time to
time, without terminating, affecting or impairing the validity of this Guaranty
or the obligations of the Parent Guarantor hereunder, the Lessor may deal with
the Guaranteed Subsidiary in the same manner and as fully as if this Guaranty
did not exist and shall be entitled, among other things, to grant the Guaranteed
Subsidiary, without notice or demand and without affecting the Parent
Guarantor's liability hereunder, such extension or extensions of time to
perform, renew, compromise, accelerate or otherwise change the time for payment
of or otherwise change the terms of payment or any part thereof contained in or
arising under the Guaranteed Agreements, or to waive any Obligation of the
Guaranteed Subsidiary to perform, any act or acts as the Lessor may deem
advisable.
   13
10. Waiver of Subrogation. The Parent Guarantor hereby expressly waives any
rights which it may acquire by way of subrogation, reimbursement, contribution
or setoff under this Guaranty, by virtue of any payment or performance made
hereunder or the realization by any holder of the Obligations on any collateral
granted by the Parent Guarantor as security therefor, or otherwise. The Parent
Guarantor hereby expressly waives any claim, right or remedy which the Parent
Guarantor may now have or hereafter acquire against the Guaranteed Subsidiary
that arises hereunder, from the performance by the Parent Guarantor hereunder,
or from the realization by any holder of the Obligations on any collateral
granted by the Parent Guarantor as security therefor, including, without
limitation, any claim, right or remedy of the Lessor or any other Persons
holding any of the Obligations against the Guaranteed Subsidiary or any security
which the Lessor or any other Persons holding any of the Obligations now have or
hereafter acquire, whether or not such claim, right or remedy arises in equity,
under contract, by statute, under color of law or otherwise. If any amount shall
be paid to the Parent Guarantor on account of such subrogation, reimbursement,
contribution or setoff rights, such amount shall be held in trust for the
benefit of the Lessor and any other holders of the Obligations and shall
forthwith be paid to the Lessor to be credited and applied upon the Obligations,
whether matured or unmatured, or to be held by the Collateral Agent as
collateral security for any Guaranteed Obligations thereafter existing. The
preceding waiver is intended by the Parent Guarantor, the Lessor and any other
holders of the Obligations to be for the benefit of the Guaranteed Subsidiary
and any of its successors and assigns as an absolute defense to any action by
the Parent Guarantor against the Guaranteed Subsidiary or its assets that arises
out of the Parent Guarantor's performance under this Guaranty. To the extent the
Parent Guarantor makes any payment hereunder or any holder of the Obligations
realizes upon any collateral granted by the Parent Guarantor as security for its
obligations hereunder, the Parent Guarantor shall be deemed to have made a
contribution to the equity capital of the Guaranteed Subsidiary in the amount of
such payment or realization.

11. Election of Remedies, Etc. Any election of remedies which results in the
denial or impairment of the right of the Lessor to seek a deficiency judgment
against the Guaranteed Subsidiary shall not impair the Parent Guarantor's
obligation to pay the full amount of the Obligations. In the event the Lessor
shall bid at any foreclosure or trustee's sale or at any private sale permitted
by law or the Related Documents, the Lessor may bid all or less than the amount
of the Obligations and the amount of such bid need not be paid by the Lessor but
shall be credited against the Obligations. The amount of the successful bid at
any such sale, whether the Lessor or any other party is the successful bidder,
shall be conclusively deemed to be the fair market value of the collateral and
the difference between such bid amount and the remaining balance of the
Obligations shall be conclusively deemed to be the amount of the obligations
guaranteed under this Guaranty, notwithstanding that any present or future law
or court decision or ruling may have the effect of reducing the amount of any
deficiency claim to which the Lessor might otherwise be entitled but for such
bidding at any such sale.
   14
12. Continuing Guaranty. The Parent Guarantor agrees that this Guaranty is a
continuing guaranty and shall remain in full force and effect until the payment
and performance in full of the Obligations. Upon payment and performance in full
of the Obligations of the Parent Guarantor, this Guaranty and all obligations of
Parent Guarantor hereunder shall be released and, upon the request of the Parent
Guarantor, the Lessor shall endorse, execute, deliver, record and file all
instruments and documents, and do all other acts and things reasonably required
to evidence or document such release.

Guaranty have been paid or discharged in full:

otherwise impair its right to receive the proceeds of such insurance.

property, service of process in the State of New York when and as such legal
actions or proceedings may be brought in the courts of the State of New York or
of the United States of America sitting in New York, and such service of process
shall be deemed complete upon the date of delivery thereof to such agent whether
or not such agent gives notice thereof to the Parent Guarantor, or upon the
earliest of any other date permitted by applicable law. It is understood that a
copy of said process served on such agent will as soon as practicable be
forwarded to the Parent Guarantor, at its address set forth in Section 18(c),
but its failure to receive such copy shall not affect in any way the service of
said process on said agent as the agent of the Parent Guarantor. The Parent
Guarantor irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the mailing of the
copies thereof by certified mail, return receipt requested, postage prepaid, to

(ii) any earlier date permitted by applicable law. The Parent Guarantor agrees
that it will at all times continuously maintain an agent to receive service of
process in the State of New York on behalf of itself and its properties and in
the event that, for any reason, the agent named above or its successor shall no
longer serve as its agent to receive service of process in the State of New York
on its behalf, it shall promptly appoint a successor so to serve and shall
advise the Lessor thereof (and shall furnish to the Lessor the consent of any
successor agent so to act). Nothing in this Section 17(b) shall affect the right
of the Lessor to bring proceedings against the Parent Guarantor in the courts of
any other jurisdiction or to serve process in any other manner permitted by
applicable law.
