                                    PAGE 5



3. PURCHASE PRICE; PAYMENT AND PREPAYMENT

     3.1  Purchase Price. In consideration of the shipment by Seller of any
Equipment, Purchaser hereby agrees to pay the Purchase Price for such Equipment,
together with interest on the Purchase Price Balance for such Equipment from
time to time, on the dates and in the amounts determined in accordance with
Section 3.2. The interest with respect to the Purchase Price Balance of each
item of Equipment shall accrue (x) from, and including, the first day of the
calendar month following the calendar month in which the Shipment Date in
respect of such Equipment occurs (y) to, but excluding, the Maturity Date for
such Equipment.

     3.2  Payments of Purchase Price Balance. On each Payment Date in respect of
each Monthly Period for each item of Equipment, the Purchaser shall pay to
Seller, an amount that equals the product of (i) the Purchase Price for such
Equipment and (ii) the factor set forth as the payment factor in Schedule I
hereto opposite such Monthly Period. The Purchaser shall also pay the
outstanding Purchase Price Balance in respect of any Equipment in full on the
Maturity Date in respect of such Equipment together with any other amounts due
in respect of such Equipment hereunder.

     3.3  Overdue Amounts. If (i) any amount payable by Purchaser pursuant to
Section 3.2 is not paid in full within ten (10) days of the due date therefor or
(ii) any other amount payable by the Purchaser under this Agreement (including,
without limitation, Section 13) or any other Conditional Sale Document is not
paid in full when due, then Purchaser shall pay to Seller, to the extent
permitted by law, an additional amount equal to interest at the Overdue Rate on
the amount not paid for each day during the period from, and including the due
date to, but excluding, the date on which such amount is paid in full.

     3.4  Payments. All payments to Seller hereunder shall be made, in Dollars,
by wire transfer in immediately available funds to Seller c/o the account of
Ascend Communications, Inc. at Wells Fargo Bank, Oakland Main Office, Oakland,
California, Account No. 52298073, ABA No.: 011 000 390, or to such other
person(s) or account(s) as Seller may designate from time to time.

     3.5  Prepayment.
          (a) Optional Prepayment. So long as no Event of Default shall have
occurred and be continuing hereunder, the Purchaser shall have the right, upon
giving at least thirty (30) days' prior written notice to Seller, to prepay the
Purchase Price Balance which is then outstanding with respect to all or any
items of Equipment provided that any prepayment in respect of less than all
items of Equipment shall be in a minimum amount of $500,000. Such notice shall
specify the amount and the date of such prepayment (which date shall be a
Payment Date) and, in the case of a prepayment in respect of less than all items
of Equipment, the Equipment to which such prepayment relates. Once given, any
such notice shall be irrevocable. On the date specified for prepayment, the
Purchaser shall pay to the Seller the amounts payable by the Purchaser on such
Payment Date pursuant to Section 3.2, the Prepayment Value of the Equipment in
respect of which the Purchase Price Balance is being prepaid and any other
amounts payable in respect of such Equipment hereunder. The Prepayment Value in
respect of any item of Equipment shall be the amount determined by the Seller to
equal the then present

                                    PAGE 6



value of the amounts that would have been payable by the Purchaser under Section
3.2 with respect to such Equipment discounted at a rate equal to the per annum
yield to maturity for United States Treasury obligations (as published in the
Wall Street Journal) as of the prepayment date with a like term maturity to the
weighted average life of such remaining payments plus 150 (one hundred fifty)
basis points.

          (b) Mandatory Prepayments. Purchaser shall immediately prepay the
aggregate Purchase Price Balance of all Equipment which is then outstanding, all
unpaid interest determined by Seller to have accrued on such amount, the
Prepayment Value in respect of such Equipment and all other amounts outstanding
hereunder, under the Note and under the other Conditional Sale Documents within
five (5) Business Days following receipt of notice from Seller (stating in
reasonable detail the basis for such notice), that this Agreement or any other
Conditional Sale Document has become, or is determined to be, illegal, invalid
or unenforceable, or for any other reason does not constitute a valid
reservation of title in the Equipment in favor of Seller, or is not effective to
continue a validly perfected first priority security interest, as the case may
be, in favor of Seller in respect of all of the Collateral, or Purchaser or any
Affiliate of Purchaser takes any action, directly or indirectly, to challenge
the legality, validity or binding effect of this Agreement, or any other
Conditional Sale Document provided that Purchaser shall not be required to make
any payment of Prepayment Value if prepayment under this Section 3.5(b) results
from facts or circumstances not within the control of, or caused by, Purchaser.

     3.6  Purchaser's Obligations Unconditional.  Purchaser's obligation to pay
the full amount of the Purchase Price and interest thereon for the Equipment and
all other amounts payable to Seller hereunder, under the Note and under the
other Conditional Sale Documents (each, a "Payment") shall be absolute and
unconditional under any and all circumstances, shall not be subject to notice or
demand unless otherwise provided herein, and shall not be affected by any
circumstance of any character, including, without limitation:  (a) any setoff,
counterclaim, deduction, recoupment, abatement, suspension, deferment,
diminution, proration, defense or other right which Purchaser may have against
Seller or any other Person for any reason whatsoever, including any claim of
Purchaser against Seller or any other Person; (b) any defect in the title,
condition, design, operation or fitness for use, or any damage to, or loss or
destruction of, or any Lien upon the Equipment or the interruption or cessation
or restriction in the use or possession thereof by Purchaser for any reason
whatsoever; (c) any condemnation, expropriation, requisition or other taking of
the Equipment; (d) any bankruptcy, insolvency, reorganization, composition,
adjustment, dissolution, liquidation or other like proceedings by or against
Purchaser, Seller or any other Person; (e) any change, extension, waiver,
indulgence or other act or omission in respect of any obligation or liability of
Purchaser or Seller except as otherwise expressly provided thereby; (f) any
failure by Purchaser or any Affiliate to obtain any anticipated tax allowances
or other tax benefits in the United States or elsewhere; or (g) any other
circumstance, happening or event whatsoever, whether or not similar to the
foregoing and whether or not Purchaser or Seller shall have had any knowledge,
actual or otherwise, of any of the foregoing.  If for any reason whatsoever this
Agreement shall be terminated in whole or in part by operation of law or
otherwise, except as specifically provided herein, Purchaser nonetheless agrees
to pay to Seller an amount equal to the aggregate Purchase Price Balance of all
Equipment at the time of payment, plus interest accrued to the date of payment,
the Prepayment Value in respect of such Equipment and all other amounts payable
hereunder and


                                    PAGE 7


under any other Conditional Sale Document, and, upon such payment in full,
Seller shall, to the extent permitted by applicable law, transfer the title to
the Equipment which has been retained by Seller hereunder to Purchaser and
otherwise comply with the provisions of Section 4.2. Except as otherwise
expressly provided hereunder, to the extent permitted by applicable law,
Purchaser waives and disclaims all rights now or hereafter conferred by statute
or otherwise to terminate, cancel, quit or surrender this Agreement or the
Equipment or to any abatement, suspension, deferment, diminution, reduction or
proration of any payment on account of any occurrence described in this
Agreement. Each payment paid by Purchaser hereunder shall be final, and
Purchaser shall not seek to recover all or any part of such payment from Seller,
or from whosoever may be entitled thereto, for any reason whatsoever.
Notwithstanding the foregoing, Purchaser shall not be required to make any
payment of Prepayment Value if payment under this Section 3.6 results from facts
or circumstances not within the control of, or caused by, Purchaser.

     3.7  Purchase Price Balance.  As long as no Default or Event of Default has
occurred and is continuing, the Purchase Price Balance, at any time of the
determination thereof, in respect of any item of Equipment will equal (x) the
product of (i) the Purchase Price for such Equipment and (ii) the factor set
forth as the purchase price balance factor in Schedule I hereto opposite the
then most recent Monthly Period in respect of which a Payment Date has occurred
minus (y) any other payments allocated to reduce the Purchase Price Balance of
such Equipment hereunder.  Upon the occurrence, and during the continuation of,
a Default or an Event of Default, the Purchase Price Balance at such time in
respect of any item of Equipment shall be such amount as the Seller may, in good
faith, determine.  The Seller shall maintain in its records a running
calculation of the Purchase Price Balance in respect of such Equipment which
calculation, absent manifest error, shall be deemed conclusively correct.  The
aggregate Purchase Price Balance of any Equipment may be adjusted upward if and
to the extent that at any time all or any part of any payment theretofore
received by Seller from or on behalf of Purchaser pursuant to Section 3.2 or
3.5(a) in respect of such Equipment, or any of the other obligations of
Purchaser hereunder or under the Note or any other Conditional Sale Document, is
or must be rescinded, released, rebated or returned by Seller to Purchaser, any
Qualified Lessee or any other person for any reason whatsoever (including,
without limitation, the insolvency, bankruptcy, winding-up or reorganization of
Purchaser, any Qualified Lessee or any other person, or in respect of any
obligation owed to any Qualified Lessee under the Lease Documents), in which
case, the obligations of Purchaser, shall, for purposes of this Agreement and
the other Conditional Sale Documents, be deemed to be readjusted or reinstated
to the extent of any such recovery notwithstanding such payment, as though such
payment had not been made.  The allocation of any such upward adjustment to the
Purchase Price Balance of the Equipment shall be made by Seller in the good
faith exercise of its reasonable discretion.

4. TITLE TO EQUIPMENT; SELLER COVENANTS

     4.1  Retention of Title by Seller; Grant of Security Interest.
Notwithstanding the shipment of the Equipment to Purchaser and its possession
and use thereof by Purchaser or any Qualified Lessee, Seller shall and does
hereby retain, to the exclusion of Purchaser to the extent permitted by
applicable law, the full title to and property interest in the Equipment and all
proceeds thereof.

                                    PAGE 8

Conditional Sale Document, Purchaser hereby grants, pledges, transfers, assigns

and the Collateral related thereto, (b) transfer to Purchaser good and
marketable title to such Equipment, free of any Liens created by or through the

such documents or take such actions evidencing such release of security interest
and transfer of title as Purchaser shall reasonably request including, without
limitation, the cancellation of all filings in respect of such Equipment which

     6.2  Representations and Warranties of Purchaser.  Purchaser makes the
following representations, warranties and covenants as of the date hereof and as
of each Shipment Date that:

          (a)  Corporate Status and Power.  The Purchaser (a) is a corporation
duly organized, validly existing and in good standing or the equivalent under
the laws of the jurisdiction of its organization, (b) has all powers required to
conduct its business, (c) has full corporate power, authority and legal right to
execute, deliver and perform this Agreement and each other Conditional Sale
Document to which it is party and to carry out the transactions contemplated
hereby.

          (b)  Due Execution and Enforceability.  Each of this Agreement and
each other Conditional Sale Document to which it is party has been duly executed
and delivered by the Purchaser and constitutes the valid and binding obligation
of the Purchaser, enforceable against Purchaser in accordance with its terms
except as such enforceability may be limited by bankruptcy or similar laws
applicable to creditors generally or by general principles of equity.

          (c)  Non-Contravention.  Neither the execution and delivery by the
Purchaser of this Agreement or any other Conditional Sale Document to which it
is a party nor the consummation by the Purchaser of the transactions
contemplated hereby or thereby is an event that, of itself or with the giving of
notice or the passage of time or both, will (a) conflict with the certificate of
incorporation or by-laws of the Purchaser; (b) violate any material judgment,
decree or order or statute, rule or regulation applicable to the Purchaser, (c)
contravene or result in any breach of, or constitute a default under any
indenture, mortgage, material contract or other material agreement to which
Purchaser is a party or by which Purchaser or any of its properties may be bound
or affected, or (d) result in the creation of any Lien (excepting the Lien
arising pursuant to the Conditional Sale Documents), charge or encumbrance upon
any property of Purchaser.

          (d)  Government Approvals.  All Governmental Approvals, if any,
required in connection with the execution and delivery by Purchaser of the
Conditional Sale Documents to which Purchaser is a party, the consummation of
the transactions by Purchaser contemplated thereby, and the performance of its
obligations thereunder, have been, or will be contemporaneously with the
delivery of the Equipment hereunder, obtained, given or accomplished.

          (e)  Litigation.  There is no action or proceeding pending or, to the
knowledge of Purchaser, overtly threatened against or affecting Purchaser or any
of the Collateral before any court or other governmental authority or
arbitration body which, if adversely determined, is reasonably likely to
materially and adversely affect the financial condition of Purchaser or the
ability of Purchaser to perform its obligations under the Conditional Sale
Documents to which it is party, or which questions in any respect, directly or
indirectly, the legality, validity, binding effect or enforceability of any of
the Conditional Sale Documents or any part or portion thereof, or any action
contemplated thereby.

          (f)  No Default.  No Default or Event of Default has occurred and is
continuing or will result from the purchase of the relevant Equipment or
consummation of the other

                                    PAGE 13


transactions contemplated by the Conditional Sale Documents; and to the best of
Purchaser's knowledge, there does not exist any material default or failure of
condition or performance under any Lease by a Qualified Lessee or by Purchaser
in its capacity as Lessor thereunder.

          (g)  All Disclosures Made.  No document, certificate or statement
furnished by Purchaser to Seller in connection with the transactions
contemplated by this Agreement contains any untrue statement of a material fact
or omits a material fact necessary to make the statements contained therein not
misleading. There is no fact which Purchaser has not disclosed to Seller in
writing which materially adversely affects or, so far as Purchaser can
reasonably foresee, will materially adversely affect the ability of Purchaser to
carry on its business and perform its obligations under this Agreement and the
other Conditional Sale Documents.

          (h)  Leases Comply with Applicable Law.  In respect of any Lease, to
the knowledge of Purchaser after reasonably inquiry, the form of Lease to be
entered into by the Purchaser and the Qualified Lessee in connection with the
corresponding Equipment complies with the requirements of all applicable laws
and contains all information and disclosures required by such applicable laws.

long as such Guarantor or Purchaser, as applicable, is the survivor and no
Default or Event of Default will result therefrom.

     7.3  Maintenance.  Purchaser shall maintain, or cause to be maintained, the
Equipment in good operating order and appearance, protect the Equipment from
deterioration, other than normal wear and tear, and will not use, or permit to

and is permitted by applicable law.

8.  POSSESSION AND USE OF THE EQUIPMENT

     8.1  Use of the Equipment.  Purchaser shall not, and shall not permit any
third party to, operate, use or locate the Equipment, or any part thereof,
except as otherwise provided in this Agreement.

     8.2  Transfer of Title or Possession.  Purchaser shall not, and shall cause
each Lessee not to, without the prior written consent of Seller, lease, sublease
or otherwise in any manner deliver, transfer or relinquish possession of the
Equipment, or sell or convey any or all of its right, title and interest in or
to any part thereof; provided, however, that, Purchaser may, without the prior

provided, that if the Purchaser and Seller are unable to agree to amendments to
the Lease required for a particular jurisdiction within 30 days from the

permitted lease had not occurred, and (2) in connection with any permitted lease
hereunder, Purchaser, at its own expense, shall take or cause to be taken all
action reasonably requested by Seller to be taken, including filings,

                                    PAGE 15


Sale Documents or its rights and interests in and to the Equipment or any part
thereof or any of the other Collateral, and if any such Lien other than any

after-tax basis, shall indemnify, protect and hold harmless Seller against all
fees, taxes and governmental charges (including, without limitation, interest
and penalties) of any nature imposed on or in any way relating to Seller,
Purchaser, any Qualified Lessee, any item of Equipment, this Agreement or any
Lease, except state and local taxes on or measured by Seller's net income (other
than any such tax which is in substitution for or relieves Purchaser from the
payment of taxes it would otherwise be obligated to pay or reimburse to Seller
as herein provided) and federal taxes on Seller's net income.  Purchaser shall,
at its expense, file when due with the appropriate authorities any and all tax
and similar returns, and reports required to be filed with respect thereto, for
which it has indemnified Seller hereunder or, if requested by Seller, notify
Seller of all such requirements and furnish Seller with all information required
for Seller to effect such filings.  Any fees, taxes or other charges paid by
Seller upon failure of Purchaser to make such payments shall, at Seller's
option, become immediately due from Purchaser to Seller and shall be subject to
the Overdue Charge from the date paid by Seller until the date reimbursed by
Purchaser.  Purchaser shall have no obligation to indemnify Seller under this
Section 9 to the extent that any tax or governmental charge results from the
failure by Seller to take all steps which are reasonable and customary in the
ordinary course of Seller's business to avail itself of any and all exemptions
from liability for, or reductions in, any such taxes or governmental charges.

10.  INSURANCE

The Purchaser shall, or shall cause the corresponding Lessee, to maintain
insurance with financially sound and reputable insurers, of the kinds and in the
amounts customarily insured against by companies engaged in the same or similar
business and similarly situated. The Purchaser shall, or shall cause the
corresponding Lessee, to pay all insurance premiums payable as and when due. The
Seller shall be named as sole loss payee or additional insured, as applicable,
with respect to each such insurance policy.

11.  RISK OF LOSS

Risk of loss in respect of each item of Equipment shall pass to Purchaser on the
Shipment Date in respect thereof.  Upon the occurrence of an Event of Loss,
Purchaser shall promptly pay to Seller the applicable Purchase Price Balance of
the Equipment subject to the Event of Loss, interest on the Purchase Price
Balance thereof from the most recent Payment Date in respect thereof to the date
of payment at a per annum rate of 13.75% and the Prepayment Value determined by
Seller with respect to such Equipment.  Upon payment by Purchaser of the amounts
in the preceding sentence, Seller will transfer to Purchaser, "AS IS, WHERE IS,

                                    PAGE 16


WITHOUT RECOURSE, REPRESENTATION OR WARRANTY," all of Lessor's right, title and
interest, if any, in such items of Equipment.

12.  INDEMNIFICATION

Purchaser assumes liability for, and shall pay when due, and shall indemnify,
reimburse and hold each Indemnified Person harmless from and against all Claims,
directly or indirectly relating to or arising out of the acquisition, use,
manufacture, purchase, shipment, transportation, delivery, installation, lease
or sublease, ownership, operation, possession, control, storage, return or
condition of any item of Equipment (regardless of whether such item of Equipment
is at the time in the possession of Purchaser), the falsity of any non-tax
representation or warranty of Purchaser or Purchaser's failure to comply with
the terms of this Agreement during the Term.  The foregoing indemnity shall
cover, without limitation, (i) any Claim in connection with a design or other
defect (latent or patent) in any item of Equipment, (ii) any Claim for
infringement of any patent, copyright, trademark or other intellectual property
right, or (iii) any Claim for negligence or strict or absolute liability in
tort; provided, however, that Purchaser shall not indemnify Seller in respect of
any Claim to the extent resulting from the gross negligence, willful misconduct
or bad faith of Seller.

Such indemnities shall continue in full force and effect, notwithstanding the
expiration or termination of this Agreement.  Upon Seller's written demand,
Purchaser shall assume and diligently conduct, at its sole cost and expense, the
entire defense of any Indemnified Person against any indemnified Claim described
in this Section 12.  Purchaser shall not settle or compromise any Claim against
or involving Seller without first obtaining Seller's written consent thereto,
which consent shall not be unreasonably withheld.  Purchaser shall give Seller
prompt notice of any occurrence, event or condition in connection with which
Seller may be entitled to indemnification hereunder.  The provisions of this
Section 12 are in addition to, and not in limitation of, the provisions of
Section 9.

13.  EVENTS OF DEFAULT

An Event of Default shall occur if (i) Purchaser fails to make any payment due
under Section 3.2 hereof within ten (10) days of the due date therefor or any
other payment required under this Agreement when due and such failure continues
for a period of three (3) days after written notice from Seller, or (ii)
Purchaser fails to perform or observe any other covenant, condition or agreement
to be performed or observed by it or breaches any provision contained in this
Agreement or in any other document furnished to Seller in connection herewith,
and such failure or breach continues for a period of thirty (30) days after
written notice from Seller, or (iii) Purchaser without Seller's consent,
attempts to assign this Agreement or sell, transfer, encumber, part with
possession (other than under a Lease permitted hereunder) of any item of
Equipment; or (iv) Purchaser makes any representation or warranty herein or in
any document furnished by Purchaser in connection herewith, which shall have
been materially false or inaccurate when made or at the time to which such
representation or warranty relates; (v) an Event of Default (as therein defined)
under any Guarantee shall occur; or (vi) Purchaser or any Qualified Lessee shall
commit an act of bankruptcy or become insolvent or bankrupt or make an
assignment for the benefit of creditors or consent to the appointment of a
trustee or receiver or either shall be

                                    PAGE 17


appointed for them or for a substantial part of its property without its
consent, or bankruptcy reorganization, or insolvency proceedings shall be
instituted by or against them, and if instituted against them, shall not be
vacated or dismissed within sixty (60) days. Any Event of Default shall be
deemed material and a substantial impairment of Seller's interests for the
purposes of this Agreement, the UCC, and any other applicable law.

14.  REMEDIES

Upon the occurrences of any Event of Default and at any time thereafter,
provided such Event of Default is then continuing, Seller may, in its
discretion, do any one or more of the following:

          (a)  accelerate the Maturity Date in respect of any or all Equipment;

          (b)  recover any accrued and unpaid amounts which are due and owing
under any Conditional Sale Document plus interest at the Overdue Rate;

          (c)  recover any amounts due under any indemnity then determinable,
plus interest at the Overdue Rate;

          (d)  require that Purchaser return the Equipment in accordance with
Section 15 hereof;

          (e)  enter the premises where such Equipment is located and take
immediate possession of and remove the same, all without liability to Seller or
its agents for such entry;

          (f)  exercise the rights of "Lessor" under any Lease;

          (g)  sell any or all of the Equipment at public or private sale, with
or without notice to Seller or advertisement, or otherwise dispose of, hold,
use, operate, lease to others or keep idle such Equipment, all free and clear of
any rights of Purchaser and without any duty to account to Purchaser for such
action or inaction or for any proceeds with respect thereto; and

          (h)  exercise any other right or remedy which may be available to it
under the UCC or other applicable law including the right to recover damages for
the breach hereof.

In addition, Purchaser shall be liable for, and reimburse Seller for, all
reasonable legal fees and all commercially reasonable costs and expenses
incurred by Seller as a result of the foregoing defaults or the exercise of
Seller's remedies, including without limitation, recovering possession of the
Equipment, selling or leasing the Equipment (including broker's and sales
representative's fees and commissions), and placing any Equipment in the
condition required by Section 15.  No remedy referred to in this Section is
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to Seller at law or in
equity.  No express or implied waiver by Seller of any default shall constitute
a waiver of any other default by Seller, or a waiver of any of Seller's right.

                                    PAGE 18


15.  RETURN OF EQUIPMENT

If required to return any Equipment to the Seller hereunder, Purchaser shall, at
its expense and risk, cause such Equipment to be removed, disassembled, and
placed in the same condition as when delivered to Seller (reasonable wear and
tear excepted) and properly crate such Equipment for shipment and deliver it to
a common carrier designated by Seller.  Purchaser will ship such Equipment,
