Gentlemen:

         This letter is to confirm that Wells Fargo Bank, National Association
("Bank"), subject to all terms and conditions contained herein, has agreed to
make available to Network Appliance, Inc. ("Borrower") a revolving line of
credit under which Bank will make advances to Borrower from time to time up to
and including July 10, 1999, not to exceed at any time the maximum principal
amount of Five Million Dollars ($5,000,000.00) ("Line of Credit"), the proceeds
of which shall be used to finance Borrower's working capital requirements.


I.       CREDIT TERMS:

         1.       LINE OF CREDIT:

         (a) Line of Credit Note. Borrower's obligation to repay advances under
the Line of Credit shall be evidenced by a promissory note substantially in the
form of Exhibit A attached hereto ("Line of Credit Note"), all terms of which
are incorporated herein by this reference.

         (b) Letter of Credit Subfeature. As a subfeature under the Line of
Credit, Bank agrees from time to time during the term thereof to issue standby
and/or sight commercial letters of credit for the account of Borrower to finance
(each, a "Letter of Credit" and collectively, "Letters of Credit"); provided
however, that the form and substance of each Letter of Credit shall be subject
to approval by Bank, in its sole discretion; and provided further, that the
aggregate undrawn amount of all outstanding Letters of Credit shall not at any
time exceed Five Million Dollars ($5,000,000.00). No Letter of Credit shall have
an expiration date more than ninety (90) days beyond the maturity date of the
Line of Credit. The undrawn amount of all Letters of Credit shall be reserved
under the Line of Credit and shall not be available for borrowings thereunder.

Letter of Credit Agreement and related documents, if any, required by Bank in
connection with the issuance thereof. Each draft paid by Bank under a Letter of
Credit shall be deemed an advance under the Line of Credit and shall be repaid
by Borrower in accordance with the terms and conditions of this letter
applicable to such advances; provided however, that if advances under the Line
of Credit are not available, for any reason, at the time any draft is paid by
Bank, then Borrower shall immediately pay to Bank the full amount of such draft,
together with interest thereon from the date such amount is paid by Bank to the
date such amount is fully repaid by Borrower, at the rate of interest applicable
to advances under the Line of Credit. In such event Borrower agrees that Bank,
in its sole discretion, may debit any demand deposit account maintained by
Borrower with Bank for the amount of any such draft.

         (c) Borrowing and Repayment. Borrower may from time to time during the
term of the Line of Credit borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions contained herein or in the Line of Credit Note; provided however,
that the total outstanding borrowings under the Line of Credit shall not at any
time exceed the maximum principal amount available thereunder, as set forth
above.


II.      INTEREST/FEES:

         1.(a) Interest. The outstanding principal balance of the Line of Credit
shall bear interest at the rate of interest set forth in the Line of Credit
Note.

of a 360-day year, actual days elapsed. Interest shall be payable at the times
and place set forth in the Line of Credit Note.

           (c) Unused Commitment Fee. Borrower shall pay to Bank a fee equal to
fifteen one-hundredths percent (0.15%) per annum (computed on the basis of a
360-day year, actual days elapsed) on the average daily unused amount of the
Line of Credit, which fee shall be calculated on a calendar quarter basis by
Bank and shall be due and payable by Borrower in arrears within ten (10) days
after each billing is sent by Bank.

           (d) Collection of Payments. Borrower authorizes Bank to collect all
interest and fees due under the Line of Credit by charging Borrower's demand

amount of such deficiency shall be immediately due and payable by Borrower.


III.  REPRESENTATIONS AND WARRANTIES:

         Borrower makes the following representations and warranties to Bank,
which representations and warranties shall survive the execution of this letter
and shall continue in full force and effect until the full and final payment,
and satisfaction and discharge, of all obligations of Borrower to Bank subject
to this letter.

         1. Legal Status. Borrower is a corporation, duly organized and existing
and in good standing under the laws of the state of California, and is qualified
or licensed to do business in all jurisdictions in which such qualification or
licensing is required or in which the failure to so qualify or to be so licensed
could have a material adverse effect on Borrower.

         2. Authorization and Validity. This letter, the Line of Credit Note,
and each other document, contract or instrument deemed necessary by Bank to
evidence any extension of credit to Borrower pursuant to the terms and
conditions hereof, or now or at any time hereafter required by or delivered to
Bank in connection with this letter (collectively, the "Loan Documents") have
been duly authorized, and upon their execution and delivery in accordance with
the provisions hereof will constitute legal, valid and binding agreements and
obligations of Borrower or the party which executes the same, enforceable in
accordance with their respective terms.

         3. No Violation. The execution, delivery and performance by Borrower of
each of the Loan Documents do not violate any provision of any law or
regulation, or contravene any provision of the Articles of Incorporation or
By-Laws of Borrower, or result in a breach of or constitute a default under any
contract, obligation, indenture or other instrument to which Borrower is a party
or by which Borrower may be bound.

         4. Litigation. There are no pending, or to the best of Borrower's
knowledge threatened, actions, claims, investigations, suits or proceedings by
or before any governmental authority, arbitrator, court or administrative agency
which could have a material adverse effect on the financial condition or
operation of Borrower other than those disclosed by Borrower to Bank in writing
prior to the date hereof.

liabilities of Borrower that are required to be reflected or reserved against

except in favor of Bank or as otherwise permitted by Bank in writing.

         6. Income Tax Returns. Borrower has no knowledge of any pending
assessments or adjustments of its income tax payable with respect to any year.

         7. No Subordination. There is no agreement, indenture, contract or
instrument to which Borrower is a party or by which Borrower may be bound that
requires the subordination in right of payment of any of Borrower's obligations
subject to this letter to any other obligation of Borrower.

         8. Permits, Franchises. Borrower possesses, and will hereafter possess,
all permits, consents, approvals, franchises and licenses required and all
rights to trademarks, trade names, patents and fictitious names, if any,
necessary to enable it to conduct the business in which it is now engaged in
compliance with applicable law.

         9. ERISA. Borrower is in compliance in all material respects with all
applicable provisions of the Employee Retirement Income Security Act of 1974, as
amended or recodified from time to time ("ERISA"); Borrower has not violated any
provision of any defined employee pension benefit plan (as defined in ERISA)
maintained or contributed to by Borrower (each, a "Plan"); no Reportable Event,
as defined in ERISA, has occurred and is continuing with respect to any Plan
initiated by Borrower; Borrower has met its minimum funding requirements under
ERISA with respect to each Plan; and each Plan will be able to fulfill its
benefit obligations as they come due in accordance with the Plan documents and
under generally accepted accounting principles.

         11. Environmental Matters. Except as disclosed by Borrower to Bank in
writing prior to the date hereof, Borrower is in compliance in all material
respects with all applicable federal or state environmental, hazardous waste,
health and safety statutes, and any rules or regulations adopted pursuant
thereto, which govern or affect any of Borrower's operations and/or properties,
including without limitation, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, the Superfund Amendments and
Reauthorization Act of 1986, the Federal Resource Conservation and Recovery Act
of 1976, and the Federal Toxic Substances Control Act, as any of the same may be
amended, modified or supplemented from time to time. None of the operations of
Borrower is the subject of any federal or state investigation evaluating whether
any remedial action involving a material expenditure is needed to respond to a
release of any toxic or hazardous waste or substance into the environment.

         8.  Arbitration.

         (a) Arbitration. Upon the demand of any party, any Dispute shall be
resolved by binding arbitration (except as set forth in (e) below) in accordance
with the terms of this letter. A "Dispute" shall mean any action, dispute, claim
or controversy of any kind, whether in contract or tort, statutory or common
law, legal or equitable, now existing or hereafter arising under or in
connection with, or in any way pertaining to, any of the Loan Documents, or any
past, present or future extensions of credit and other activities, transactions
or obligations of any kind related directly or indirectly to any of the Loan
Documents, including without limitation, any of the foregoing arising in
connection with the exercise of any self-help, ancillary or other remedies
pursuant to any of the Loan Documents. Any party may by summary proceedings
bring an action in court to compel arbitration of a Dispute. Any party who fails
or refuses to submit to arbitration following a lawful demand by any other party
shall bear all costs and expenses incurred by such other party in compelling
arbitration of any Dispute.

         (b) Governing Rules. Arbitration proceedings shall be administered by
the American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon 

<PAGE>   13

Network Appliance, Inc.
July 10, 1998
Page 13


in accordance with the AAA Commercial Arbitration Rules. All Disputes submitted
to arbitration shall be resolved in accordance with the Federal Arbitration Act
(Title 9 of the United States Code), notwithstanding any conflicting choice of
law provision in any of the Loan Documents. The arbitration shall be conducted
at a location in California selected by the AAA or other administrator. If there
is any inconsistency between the terms hereof and any such rules, the terms and
procedures set forth herein shall control. All statutes of limitation applicable
to any Dispute shall apply to any arbitration proceeding. All discovery
activities shall be expressly limited to matters directly relevant to the
Dispute being arbitrated. Judgment upon any award rendered in an arbitration may
be entered in any court having jurisdiction; provided however, that nothing
contained herein shall be deemed to be a waiver by any party that is a bank of
the protections afforded to it under 12 U.S.C. Section 91 or any similar
applicable state law.

         (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

         (d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be
active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise in the substantive law
applicable to the subject matter of the Dispute. Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing. Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the state of California, (ii) may grant
any remedy or relief that a court of the state of California could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award recovery of all
costs and fees, to impose sanctions and to take such other actions as they deem
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure, the California Rules of Civil Procedure or other applicable
law. Any Dispute in which the amount in controversy is $5,000,000 or less shall
be decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees

and expenses). By submission to a single arbitrator, each party expressly waives
any right or claim to recover more than $5,000,000. Any Dispute in which the
amount in controversy exceeds $5,000,000 shall be decided by majority vote of a
panel of three arbitrators; provided however, that all three arbitrators must
actively participate in all hearings and deliberations.

         (e) Judicial Review. Notwithstanding anything herein to the contrary,
in any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law. In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
California, and (iii) the parties shall have in addition to the grounds referred
to in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
California. Judgment confirming an award in such a proceeding may be entered
only if a court determines the award is supported by substantial evidence and
not based on legal error under the substantive law of the state of California.

         (f) Real Property Collateral; Judicial Reference. Notwithstanding
anything herein to the contrary, no Dispute shall be submitted to arbitration if
the Dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or benefits
that might accrue to them by virtue of the single action rule statute of
California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable. If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638. A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures.

Judgment upon the decision rendered by a referee shall be entered in the court
in which such proceeding was commenced in accordance with California Code of
Civil Procedure Sections 644 and 645.

         (g) Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any judicial review rights
set forth herein. If more than one agreement for arbitration by or between the
parties potentially applies to a Dispute, the arbitration provision most
directly related to the Loan Documents or the subject matter of the Dispute
shall control. This arbitration provision shall survive termination, amendment
or expiration of any of the Loan Documents or any relationship between the
parties.
