                                                                     EXHIBIT 4.5

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER 
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") AND ARE "RESTRICTED 
SECURITIES" AS DEFINED IN RULE 144 PROMULGATED UNDER THE ACT. THE SECURITIES 
MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE DISTRIBUTED EXCEPT (i) IN 
CONJUNCTION WITH AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER THE 
ACT OR (ii) IN COMPLIANCE WITH RULE 144, OR (iii) PURSUANT TO AN OPINION OF 
COUNSEL, SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION OR COMPLIANCE IS 
NOT REQUIRED AS TO SAID SALE, OFFER OR DISTRIBUTION.


                        WARRANT TO PURCHASE A MAXIMUM OF

                  3,135 SHARES OF SERIES C PREFERRED STOCK OF

                             JUNIPER NETWORKS, INC.

                         (Void after December 15, 2003)

          This certifies that VENTURE LENDING & LEASING, INC., a Maryland 
corporation, or assigns (the "Holder"), for value received, is entitled to 
purchase from Juniper Networks, Inc. a California corporation (the "Company"), 
Three Thousand One Hundred Thirty-five (3,135) fully paid and nonassessable 
shares of the Company's Series C Preferred Stock ("Preferred Stock") for cash 
at a price of Eight and 93/100 Dollars ($8.93) per share (the "Stock Purchase 
Price") at any time or from time to time up to and including 5:00 p.m. (Pacific 
time) on December 15, 2003 (the "Expiration Date"), upon surrender to the 
Company at its principal office at 385 Ravendale Drive, Mountain View, 
California 94043 (or at such other location as the Company may advise Holder 
in writing) of this Warrant properly endorsed with the Form of Subscription 
attached hereto duly filled in and signed and upon payment in cash or by check 
of the aggregate Stock Purchase Price for the number of shares for which this 
Warrant is being exercised determined in accordance with the provisions hereof. 
The Stock Purchase Price and the number of shares purchasable hereunder are 
subject to adjustment as provided in Section 4 of this Warrant.

This Warrant is subject to the following terms and conditions:

     1.   Exercise; Issuance of Certificates; Payment for Shares.

          (a)  Unless an election is made pursuant to clause (b) of this Section
1, this Warrant shall be exercisable at the option of the Holder, at any time or
from time to time, on or before the Expiration Date for all or any portion of
the shares of Preferred Stock (but not for a fraction of a share) which may be
purchased hereunder for the Stock Purchase Price multiplied by the number of
shares to be purchased. In the event, however, that pursuant to the Company's
Articles of Incorporation, as amended, an event causing automatic conversion of
the Company's Preferred Stock shall have occurred prior to the exercise of this
Warrant, in whole or in part, then this Warrant shall be exercisable for the
number of shares of Common Stock of the Company into which the Preferred Stock
not purchased upon any prior exercise of the Warrant would have been so
converted (and, where the context requires, reference to "Preferred Stock" shall
be deemed to include such Common Stock). The Company agrees that the shares of
Preferred Stock purchased under this Warrant shall be and are deemed to be
issued to the holder hereof as the record owner of such shares as of the close
of business on the date on which this Warrant shall have been surrendered and
payment made for such shares. Subject to the provisions of Section 2,
certificates for the shares of

   2
Preferred Stock so purchased, together with any other securities or property to 
which the Holder hereof is entitled upon such exercise, shall be delivered to 
the Holder hereof by the Company at the Company's expense within a reasonable 
time after the rights represented by this Warrant have been so exercised. 
Except as provided in clause (b) of this Section 1, in case of a purchase of 
less than all the shares which may be purchased under this Warrant, the Company 
shall cancel this Warrant and execute and deliver a new Warrant or Warrants of 
like tenor for the balance of the shares purchasable under the Warrant 
surrendered upon such purchase to the Holder hereof within a reasonable time. 
Each stock certificate so delivered shall be in such denominations of Preferred 
Stock as may be requested by the Holder hereof and shall be registered in the 
name of such Holder or such other name as shall be designated by such Holder, 
subject to the limitations contained in Section 2.

          (b)  The Holder, in lieu of exercising this Warrant by the payment of 
the Stock Purchase Price pursuant to clause (a) of this Section 1, may elect, 
at any time on or before the Expiration Date, to receive that number of shares 
of Preferred Stock equal to the quotient of: (i) the difference between (A) the 
Per Share Price (as hereinafter defined) of the Preferred Stock, less (B) the 
Stock Purchase Price then in effect, multiplied by the number of shares of 
Preferred Stock the Holder would otherwise have been entitled to purchase 
hereunder pursuant to clause (a) of this Section 1 (or such lesser number of 
shares as the Holder may designate in the case of a partial exercise of this 
Warrant); over (ii) the Per Share Price.

          (c)  For purposes of clause (b) of this Section 1, "Per Share Price" 
means: (i) if the Company's Common Stock is then listed or admitted to trading 
on any national securities exchange or traded on any national market system, 
the average of the closing bid and asked prices of the Company's Common Stock 
as reported on such exchange or market system for the ten (10) consecutive 
trading days prior to the date of the Holder's election to convert hereunder; 
(ii) if this Warrant is being converted in conjunction with a public offering 
of stock, the price to the public per share pursuant to the offering; or (iii) 
if no shares of the Company's Common Stock are listed or admitted to trading on 
any national securities exchange or traded on any national market system, the 
price per share which the Company would obtain from a willing buyer for shares 
sold by the Company from authorized but unissued shares as such price shall be 
determined in good faith by the Company's Board of Directors.

     2.   Limitation on Transfer.

          (a)  The Warrant and the Preferred Stock shall not be transferable 
except upon the conditions specified in this Section 2, which conditions are 
intended to insure compliance with the provisions of the Securities Act. Each 
holder of this Warrant or the Preferred Stock issuable hereunder will cause any 
proposed transferee of the Warrant or Preferred Stock to agree to take and hold 
such securities subject to the provisions and upon the conditions specified in 
this Section 2.

          (b)  Each certificate representing (i) this Warrant, (ii) the 
Preferred Stock, (iii) shares of the Company's Common Stock issued upon 
conversion of the Preferred Stock and (iv) any other securities issued in 
respect of the Preferred Stock or Common Stock issued upon conversion of the 
Preferred Stock upon any stock split, stock dividend, recapitalization, merger, 
consolidation or similar event, shall (unless otherwise permitted by the 
provisions of this Section 2 or unless such securities have been registered 
under the Securities Act or sold under Rule 144) be stamped or otherwise 
imprinted with a legend substantially in the following form set forth on the 
first page of this Warrant.



                                       2
   3
(c)  The Holder of this Warrant and each person to whom this Warrant is 
subsequently transferred represents and warrants to the Company (by acceptance 
of such transfer) that it will not transfer the Warrant (or securities issuable 
upon exercise hereof unless a registration statement under the Securities Act 
was in effect with respect to such securities at the time of issuance thereof) 
except pursuant to (i) an effective registration statement under the Securities 
Act, (ii) Rule 144 under the Securities Act (or any other rule under the 
Securities Act relating to the disposition of securities), or (iii) an opinion 
of counsel, reasonably satisfactory to counsel for the Company, that an 
exemption from such registration is available.

     3.   Shares to be Fully Paid; Reservation of Shares. The Company covenants 
and agrees that all shares of Preferred Stock which may be issued upon the 
exercise of the rights represented by this Warrant will, upon issuance, be duly 
authorized, validly issued, fully paid and nonassessable and free from all 
preemptive rights of any shareholder and free of all taxes, liens and charges 
with respect to the issue thereof. The Company further covenants and agrees 
that during the period within which the rights represented by this Warrant may 
be exercised, the Company will at all times have authorized and reserved, for 
the purpose of issue or transfer upon exercise of the subscription rights 
evidenced by this Warrant, a sufficient number of shares of authorized but 
unissued Preferred Stock, or other securities and property, when and as 
required to provide for the exercise of the rights represented by this Warrant. 
The Company will take all such action as may be necessary to assure that such 
shares of Preferred Stock may be issued as provided herein without violation of 
any applicable law or regulation, or of any requirements of any domestic 
securities exchange upon which the Preferred Stock may be listed. The Company 
will not take any action which would result in any adjustment of the Stock 
Purchase Price (as defined in Section 4 hereof) (i) if the total number of 
shares of Preferred Stock issuable after such action upon exercise of all 
outstanding warrants, together with all shares of Preferred Stock then 
outstanding and all shares of Preferred Stock then issuable upon exercise of 
all options and upon the conversion of all convertible securities then 
outstanding, would exceed the total number of shares of Preferred Stock then 
authorized by the Company's Articles of Incorporation, or (ii) if the total 
number of shares of Common Stock issuable after such action upon the conversion 
of all such shares of Preferred Stock together with all shares of Common Stock 
then outstanding and then issuable upon exercise of all options and upon the 
conversion of all convertible securities then outstanding would exceed the 
total number of shares of Common Stock then authorized by the Company's 
Articles of Incorporation.

     4.   Adjustment of Stock Purchase Price Number of Shares. The Stock 
Purchase Price and the number of shares purchasable upon the exercise of this 
Warrant shall be subject to adjustment from time to time upon the occurrence of 
certain events described in this Section 4. Upon each adjustment of the Stock 
Purchase Price, the Holder of this Warrant shall thereafter be entitled to 
purchase, at the Stock Purchase Price resulting from such adjustment, the 
number of shares obtained by multiplying the Stock Purchase Price in effect 
immediately prior to such adjustment by the number of shares purchasable 
pursuant hereto immediately prior to such adjustment, and dividing the product 
thereof by the Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock. In case the Company shall 
at any time subdivide its outstanding shares of Preferred Stock into a greater 
number of shares, the Stock Purchase Price in effect immediately prior to such 
subdivision shall be proportionately reduced, and conversely, in case the 
outstanding shares of Preferred Stock of the Company shall be combined into a 
smaller number of shares, the Stock Purchase Price in effect immediately prior 
to such combination shall be proportionately increased.



                                       3
   4
          4.2  Dividends in Preferred Stock, Other Stock, Property, 
Reclassification. If at any time or from time to time the holders of Preferred 
Stock (or any shares of stock or other securities at the time receivable upon 
the exercise of this Warrant) shall have received or become entitled to 
receive, without payment therefor,

               (a)  Preferred Stock, or any shares of stock or other securities 
whether or not such securities are at any time directly or indirectly 
convertible into or exchangeable for Preferred Stock, or any rights or options 
to subscribe for, purchase or otherwise acquire any of the foregoing by way of 
dividend or other distribution, or

               (b)  any cash paid or payable otherwise than as a cash dividend, 
or

               (c)  Preferred Stock or other additional stock or other 
securities or property (including cash) by way of spinoff, split-up, 
reclassification, combination of shares or similar corporate rearrangement, 
(other than shares of Preferred Stock issued as a stock split, adjustments in 
respect of which shall be covered by the terms of Section 4.1 above), then and 
in each such case, the Holder hereof shall, upon the exercise of this Warrant, 
be entitled to receive, in addition to the number of shares of Preferred Stock 
receivable thereupon, and without payment of any additional consideration 
therefore, the amount of stock and other securities and property (including 
cash in the cases referred to in clauses (b) and (c) above) which such Holder 
would hold on the date of such exercise had he been the holder of record of 
such Preferred Stock as of the date on which holders of Preferred Stock 
received or became entitled to receive such shares and/or all other additional 
stock and other securities and property.

          4.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
If any capital reorganization of the capital stock of the Company, or any 
consolidation or merger of the Company with another corporation, shall be
effected in such a way that holders of Preferred Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Preferred
Stock, then, as a condition of such reorganization, reclassification,
consolidation, merger or sale, lawful and adequate provisions shall be made
whereby the holder hereof shall thereafter have the right to purchase and
receive (in lieu of the shares of the Preferred Stock of the Company immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby) such shares of stock, securities or assets as may be issued
or payable with respect to or in exchange for a number of outstanding shares of
such Preferred Stock equal to the number of shares of such stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby. In any such case, appropriate provision shall be made with
respect to the rights and interests of the holder of this Warrant to the end
that the provisions hereof (including, without limitation, provision for
adjustments of the Stock Purchase Price and of the number of shares purchasable
and receivable upon the exercise of this Warrant) shall thereafter be
applicable, as nearly as may be possible, in relation to any shares of stock,
securities or assets thereafter deliverable upon the exercise hereof. The
Company will not effect any such consolidation, merger or sale unless, prior to
the consummation thereof, the successor corporation (if other than the Company)
resulting from such consolidation or the corporation purchasing such assets
shall assume by written instrument, executed and mailed or delivered to the
registered Holder hereof at the last address of such Holder appearing on the
books of the Company, the obligation to deliver to such Holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such Holder may be entitled to purchase.

          4.4  Sale or Issuance Below Purchase Price. If the Company shall at
any time or from time to time issue or sell any of its Common Stock, Preferred
Stock, options to acquire (or rights to acquire such options), or any other
securities convertible into or exercisable for Common Stock, for a consideration
per share less than the Stock Purchase Price in effect immediately prior to the
time of such issue or sale, the Stock Purchase Price then in effect and then
applicable for any subsequent period or periods shall be adjusted to a price
determined by dividing (i) an amount equal to the sum of (x) the number of
shares of Common Stock outstanding immediately prior to such issue or sale
multiplied by the Stock Purchase Price then in effect and (y) the consideration,
if any, received by the Company upon such issue or sale, by (ii) the total
number of shares of Common Stock outstanding immediately after such issue or
sale. For purposes of this Section 4.4, all shares of Common Stock issued or
issuable (i) upon conversion of the Preferred Stock into Common Stock; (ii) upon
exercise of options to officers, directors and employees of and consultants to,
the corporation pursuant to plans, arrangements or agreements approved by the
Board; (iii) as a dividend or distribution on Preferred Stock or Common Stock or
any event for which adjustment is made; or (iv) upon exercise of any warrants to
purchase shares of Common Stock or Preferred Stock convertible into shares of
Common Stock in conjunction with equipment leases or other commercial financing
transactions approved by the Board, shall be deemed to be outstanding. The
foregoing notwithstanding, no adjustment shall be made pursuant to this Section
4.4 on account of a given sale to the extent that (a) the Stock Purchase Price
is adjusted pursuant to any other Section of this Warrant or (b) the conversion
price of the Preferred Stock is decreased pursuant to the terms thereof.

          4.5  Notice of Adjustment. Upon any adjustment of the stock Purchase 
Price, and/or any increase or decrease in the number of shares purchasable upon 
the exercise of this Warrant the Company shall give written notice thereof, by 
first class mail, postage prepaid, addressed to the registered holder of this 
Warrant at the address of such holder as shown on the books of the Company. The 
notice shall be signed by the Company's chief financial officer and shall state 
the Stock Purchase Price resulting from such adjustment and the increase or 
decrease, if any, in the number of shares purchasable at such price upon the 
exercise of this Warrant, setting forth in reasonable detail the method of 
calculation and the facts upon which such calculation is based.

          4.6  Other Notices. If at any time:

               (a) the Company shall declare any cash dividend upon its 
Preferred Stock;

               (b) the Company shall declare any dividend upon its Preferred 
Stock payable in stock or make any special dividend or other distribution to 
the holders of its Preferred Stock;

               (c) the Company shall offer for subscription pro rata to the 
holders of its Preferred Stock any additional shares of stock of any class or 
other rights;

               (d) there shall be any capital reorganization or 
reclassification of the capital stock of the Company, or consolidation or 
merger of the Company with, or sale of all or substantially all of its assets 
to, another corporation;

               (e) there will be a voluntary dissolution, liquidation or 
winding-up of the Company; or




                                       5


   6

               (f)  the Company shall take or propose to take any other action, 
notice of which is actually provided to holders of the Preferred Stock;

then, in any one or more of said cases, the Company shall give, by first class 
mail, postage prepaid, addressed to the holder of this Warrant at the address 
of such holder as shown on the books of the Company, (i) at least 20 day's 
prior written notice of the date on which the books of the Company shall close 
or a record shall be taken for such dividend, distribution or subscription 
rights or for determining rights to vote in respect of any such reorganization, 
reclassification, consolidation, merger, sale, dissolution, liquidation or 
winding-up, or other action and (ii) in the case of any such reorganization, 
reclassification, consolidation, merger, sale, dissolution, liquidation or 
winding-up, or other action, at least 20 day's written notice of the date when 
the same shall take place. Any notice given in accordance with the foregoing 
clause (i) shall also specify, in the case of any such dividend, distribution 
or subscription rights, the date on which the holders of Preferred Stock shall 
be entitled thereto. Any notice given in accordance with the foregoing clause 
(ii) shall also specify the date on which the holders of Preferred Stock shall 
be entitled to exchange their Preferred Stock for securities or other property 
deliverable upon such reorganization, reclassification, consolidation, merger, 
sale, dissolution, liquidation or winding-up, or other action as the case may 
be.

          4.7  Certain Events. If any change in the outstanding Preferred Stock 
of the Company or any other event occurs as to which the other provisions of 
this Section 4 are not strictly applicable or if strictly applicable would not 
fairly protect the purchase rights of the Holder of the Warrant in accordance 
with the essential intent and principles of such provisions, then the Board of 
Directors of the Company shall make an adjustment in the number and class of 
shares available under the Warrant, the Stock Purchase Price and/or the 
application of such provisions, in accordance with such essential intent and 
principles, so as to protect such purchase rights as aforesaid. The adjustment 
shall be such as will give the Holder of the Warrant upon exercise for the same 
aggregate Stock Purchase Price the total number, class and kind of shares as he 
would have owned had the Warrant been exercised prior to the event and had he 
continued to hold such shares until after the event requiring adjustment.

     5.  Issue Tax. The issuance of certificates for shares of Preferred Stock 
upon the exercise of the Warrant shall be made without charge to the Holder of 
the Warrant for any issue tax in respect thereof; provided, however, that the 
Company shall not be required to pay any tax which may be payable in respect of 
any transfer involved in the issuance and delivery of any certificate in a name 
other than that of the then Holder of the Warrant being exercised.

     6.  Closing of Books. The Company will at no time close its transfer books 
against the transfer of any Warrant or of any shares of Preferred Stock issued 
or issuable upon the exercise of any warrant in any manner which interferes 
with the timely exercise of this Warrant.

     7.  No Voting or Dividend Rights; Limitation of Liability. Nothing 
contained in this Warrant shall be construed as conferring upon the Holder 
hereof the right to vote or to consent as a shareholder in respect of meetings 
of shareholders for the election of directors of the Company or any other 
matters or any rights whatsoever as a shareholder of the Company. No dividends 
or interest shall be payable or accrued in respect of this Warrant or the 
interest represented hereby or the shares purchasable hereunder until, and only 
to the extent that, this Warrant shall have been exercised,. No provisions 
hereof, in the absence of affirmative action by the holder to purchase shares 
of Preferred Stock, and no mere enumeration herein of the



                                       6

   7
rights or privileges of the Holder hereof, shall give rise to any liability of 
such Holder for the Stock Purchase Price or as a shareholder of the Company, 
whether such liability is asserted by the Company or by its creditors.

     8.  [Intentionally omitted]

     9.  Registration Rights. The Holder hereof shall be entitled, with respect 
to the shares of Preferred Stock issued upon exercise hereof or the shares of 
Common Stock or other securities issued upon conversion of such Preferred Stock 
as the case may be, to all of the registration rights set forth in the First 
Amended Registration Rights Agreement dated as of August 5, 1996 to the same 
extent and or the same terms and conditions as possessed by the Series C 
Holders thereunder. The Company shall take such action as may be reasonably 
necessary to assure that the granting of such registration rights to the Holder 
does not violate the provisions of such agreement or any of the Company's 
charter documents or rights of prior grantees of registration rights.

     10. Rights and Obligations Survive Exercise of Warrant. The rights and 
obligations of the Company, of the Holder of this Warrant and of the holder of 
shares of Preferred Stock issued upon exercise of this Warrant, contained in 
Sections 6, 8 and 9 shall survive the exercise of this Warrant.

     11. Modification and Waiver. This Warrant and any provision hereof may be 
changed, waived, discharged or terminated only by an instrument in writing 
signed by the party against which enforcement of the same is sought.

     12. Notices. Any notice, request or other document required or permitted 
to be given or delivered to the holder hereof or the Company shall be deemed to 
have been given (i) upon receipt if delivered personally or by courier (ii) 
upon confirmation of receipt if by telecopy or (iii) three business days after 
deposit in the United States mail, with postage prepaid and certified or 
registered, to each such holder at its address as shown on the books of the 
Company or to the Company at the address indicated therefor in the first 
paragraph of this Warrant.

     13. Binding Effect on Successors. This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets. All of the obligations of the
Company relating to the Preferred Stock issuable upon the exercise of this
Warrant shall survive the exercise and termination of this Warrant. All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assign of the holder hereof. The Company will, at the time of the
exercise of this Warrant, in whole or in part, upon request of the Holder hereof
but at the Company's expense, acknowledge in writing its continuing obligation
to the Holder hereof in respect of any rights (including, without limitation,
any right to registration of the shares of Common Stock) to which the holder
hereof shall continue to be entitled after such exercise in accordance with this
Warrant; provided, that the failure of the holder hereof to make any such
request shall not affect the continuing obligation of the Company to the Holder
hereof in respect of such rights.

     14. Descriptive Headings and Governing Law. The descriptive headings of 
the several sections and paragraphs of this Warrant are inserted for 
convenience only and do not constitute a part of this Warrant. This Warrant 
shall be construed and enforced in accordance with, and the rights of the 
parties shall be governed by, the laws of the State of California.

     15. Lost Warrants or Stock Certificates. The Company represents and 
warrants to the Holder hereof that upon receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction, or mutilation of 


                                       7
   8
any Warrant or stock certificate and, in the case of any such loss, theft or
destruction, upon receipt of an indemnity reasonably satisfactory to the
Company, or in the case of any such mutilation upon surrender and cancellation
of such Warrant or stock certificate, the Company at its expense will make and
deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost,
stolen, destroyed or mutilated Warrant or stock certificate.

     16.  Fractional Shares. No fractional shares shall be issued upon exercise
of this Warrant. The Company shall, in lieu of issuing any fractional share, pay
the holder entitled to such fraction a sum in cash equal to such fraction
