     THIS EMPLOYMENT AGREEMENT (the "AGREEMENT"), dated as of November 9, 
1998, is by and between FirstWorld Communications, Inc., a Delaware 
corporation (the "COMPANY") and Marion K. Jenkins ("EXECUTIVE").

                                    RECITAL

     The Company desires to employ Executive, effective as of November 9, 
1998 (the "COMMENCEMENT DATE"), on the terms and conditions set forth in this 
Agreement, and Executive desires to be so employed.

                                  AGREEMENT

     IN CONSIDERATION of the premises and the mutual covenants set forth 
below, the parties hereby agree as follows:

     1.   EMPLOYMENT.  The Company hereby agrees to employ Executive as 
Senior Vice President and Chief Information Officer of the Company, and 
Executive hereby accepts such employment, on the terms and conditions 
hereinafter set forth.

     2.   TERM.  The period of employment of Executive by the Company 
hereunder (the "EMPLOYMENT PERIOD") shall commence at the Commencement Date 
and shall continue through October 31, 2000.  The Employment Period may be 
sooner terminated by either party in accordance with Section 5 of this 
Agreement.

     3.   POSITION AND DUTIES.  During the Employment Period, Executive shall 
serve as Senior Vice President and Chief Information Officer of the Company. 
Executive shall devote such time, attention and energies to Company affairs 
as are necessary to fully perform his duties (other than absences due to 
illness or vacation) for the Company.  During the Employment Period, 
Executive shall not, directly or indirectly, render services to any other 
organization, entity or person, as an employee, independent contractor, 
consultant or otherwise, with or without compensation, without the prior 
written consent of the Board of Directors of the Company (the "BOARD")

     4.   COMPENSATION AND RELATED MATTERS.

          (a)  SALARY.  During the Employment Period, the Company shall pay 
Executive an annual base salary of $160,000 per year ("BASE SALARY"). 
Executive's Base Salary shall be paid in approximately equal installments in 
accordance with the Company's customary payroll schedule and practices. 
Executive's Base Salary shall be subject to annual reviews commencing 
November 1999 and each year thereafter.  If Executive's Base Salary is 
increased by the Company, such increased Base Salary shall then constitute 
the Base Salary for all purposes of this Agreement. All compensation paid to 
Executive shall be subject to withholding and other employment taxes imposed 
by applicable law.

          (b)  ANNUAL BONUS. The Board's compensation committee (the 
"COMPENSATION COMMITTEE") shall review Executive's performance at least once 
annually during each year of the Employment Period and, based on Executive's 
performance, recommend whether the Company should award Executive a cash 
bonus ("BONUS") in order to reward Executive for services rendered to the 
Company and/or as an incentive for continued service to the Company.  The 
amount of Executive's Bonus, if any, shall be determined in the reasonable 
discretion of the Compensation Committee and shall be dependent upon, among 
other things, the achievement of certain performance levels by the Company, 
including, without limitation, (i) the nature, magnitude and quality of the 
services performed by Executive for the Company, (ii) the condition 
(financial and other) and results of operations of the Company and (iii) the 
compensation paid for positions of comparable responsibility and authority 
within the telecommunications industry. The targeted amount of Executive's 
Bonus shall be an amount equal to 50% of Base Salary at 100% completion of 
applicable performance levels, to be set forth in the Company's Annual Bonus 
Plan.

          (c)  STOCK OPTIONS.  Effective as of the Commencement Date, 
Executive shall be awarded a stock option (the "STOCK OPTION") to purchase 
250,000 shares of the Company's Series B Common Stock, par value $.0001 per 
share (the "Common Stock").  The shares of Common Stock subject to the Stock 
Option shall vest in increments of 62,500 shares on each of the first, 
second, third and fourth anniversaries of the Commencement Date, with the 
shares in the first such increment having an exercise price of $6.00, shares 
in the second such increment having an exercise price of $6.50, shares in the 
third such increment having an exercise price of $7.00 and shares in the 
fourth such increment having an exercise price of $7.50.  The Stock Option 
will be granted under one of the Company's stock option plans and the terms 
and conditions of the Stock Option will be determined in accordance with the 
applicable stock option plan.

          (d)  EXPENSES.  The Company shall promptly reimburse Executive for 
all reasonable business expenses upon the presentation of reasonably itemized 
statements of such expenses in accordance with the Company's policies and 
procedures now in force or as such policies and procedures may be modified 
with respect to all senior executive officers of the Company.

          (e)  WELFARE AND PENSION PLANS.  In addition to Executive's Base 
Salary and any incentive compensation and bonuses awarded to Executive 
hereunder, he (and his family) shall be entitled to participate, to the 
extent that he is (and they are) eligible under the terms and conditions 
thereof, in any pension, retirement, hospitalization, insurance, disability 
or medical service plan generally available to the executive officers of the 
Company that may be in effect from time to time during the Employment Period. 
The Company shall be under no obligation to institute or continue the 
existence of any such employee benefit plan.

     5.   TERMINATION.  Executive's employment hereunder may be terminated 
during the Employment Period under the following circumstances:

          (a)  DEATH.  Executive's employment hereunder shall terminate upon

          (b)  DISABILITY.  If, as a result of Executive's incapacity due to 
physical or mental illness, Executive shall have been substantially unable to 
perform his duties hereunder for an entire period of sixty (60) consecutive 
days, and within thirty (30) days after written Notice of Termination (as 
defined in Section 6(a)) is given after such sixty (60) day period, Executive 
shall not have returned to the substantial performance of his duties on a 
full-time basis, the Company shall have the right to terminate Executive's 
employment hereunder for "Disability," and such termination in and of itself 
shall not be, nor shall it be deemed to be, a breach of this Agreement.

          (c)  CAUSE.  The Company shall have the right to terminate 
Executive's employment for Cause (as defined), and such termination in and of 
itself shall not be, nor shall it be deemed to be, a breach of this 
Agreement.  For purposes of this Agreement, the Company shall have "Cause" to 
terminate Executive's employment upon Executive's:

               (i)   conviction of, or plea of guilty or nolo contendere to,
     any crime constituting a felony;

               (ii)  commission of a material act of dishonesty, fraud,
     misrepresentation or other act of moral turpitude that would, in the
     Board's reasonable judgment, prevent the effective performance of his
     duties hereunder;

               (iii) continued failure to substantially perform his duties
     hereunder to the reasonable satisfaction of the Board (other than such
     failure resulting from Executive's incapacity due to physical or mental
     illness or subsequent to the issuance of a Notice of Termination by
     Executive for Good Reason (as defined in Section 5(d)) after demand for
     substantial performance is delivered by the Board in writing that
     specifically identifies the manner in which the Board believes Executive
     has not used reasonable best efforts to substantially perform his duties;
     or

               (iv)  willful misconduct (including, but not limited to, a
     willful breach of the provisions of Section 8) that is, in the Board's
     reasonable judgment, injurious to the Company or to any entity in control
     of, controlled by or under common control with the Company ("AFFILIATE").

     For purposes of this Section 5(c), no act, or failure to act, by 
Executive shall be considered "willful" unless committed in bad faith and 
without a reasonable belief that the act or omission was in the best 
interests of the Company or any Affiliates thereof; PROVIDED, HOWEVER, that 
the requirements outlined in paragraphs (iii) or (iv) above shall be deemed 
to have occurred if Executive's action or non-action continues for more than 
ten (10) days after Executive has received written notice of the 
inappropriate action or non-action. This Section 5(c) shall not prevent 
Executive from challenging the Board's determination that Cause exists or 
that Executive has failed to cure any act (or failure to act) that 
purportedly formed the basis for the Board's determination, under the 
arbitration procedures set forth in Section 10 below.

          (d)  GOOD REASON.  Executive may terminate his employment for "Good 
Reason" within thirty (30) days after Executive has actual knowledge of the 
occurrence, without 



                                      3
<PAGE>

the written consent of Executive, of one of the following events that has not 
been cured within thirty (30) days after written notice thereof has been 
given by Executive to the Company (PROVIDED, that with respect to this 
Section 5(d), the Company shall have the right to challenge Executive's 
determination that he has the right to terminate his employment for "Good 
Reason" under the arbitration procedures set forth in Section 10 below):

               (i)   a reduction by the Company in Executive's Base Salary or a
     failure by the Company to pay any such amounts when due;

               (ii)  any purported termination of Executive's employment for
     Cause which is not effected pursuant to the procedures of Section 5(c) (and
     for purposes of this Agreement, no such purported termination shall be
     effective);

               (iii) the Company's failure to provide the Stock Option or the
     Company's material breach of one or more of the stock option agreements
     pursuant to which the Stock Option was issued to Executive;

               (iv)  the Company's failure to substantially provide any
     material employee benefits due to be provided to Executive;

               (v)   the Company's failure to provide in all material respects
     the indemnification set forth in the agreement referenced in Section 9 of
     this Agreement;

               (vi)  the relocation of the Company's corporate headquarters
     (which are currently located in San Diego but which are being relocated to
     the Denver metropolitan area) more than 100 miles from the Denver
     metropolitan area; or

               (vii) in connection with a Change in Control (as defined below)
     of the Company, Executive's responsibilities are reduced such that he is no
     longer serving as Senior Vice President and Chief Information Officer of
     the Company or in a reasonably similar capacity.

For purposes of this Agreement, a "Change in Control" of the Company means 
the occurrence of one of the following events:

               (1)   the sale, lease, transfer conveyance or other disposition,
     in one or a series of related transactions, of all or substantially all of
     the assets of the Company and its subsidiaries, taken as a whole, to any
     person (as such term is defined in Section 3(a)(9) of the Securities
     Exchange Act of 1934, as amended (the "EXCHANGE ACT")) or group (as such
     term is defined in Section 13(d)(3) of the Exchange Act and Section
     14(d)(2) of the Exchange Act);


               (2)  the adoption of a plan relating to the liquidation or 
     dissolution of the Company; or



                                      4
<PAGE>

               (3)   any person (as defined above) or group (as defined above)
     other than the Permitted Holders (as defined below) is or becomes the
     Beneficial Owner (as defined below), directly or indirectly, of 50% or more
     of the total voting stock or total common equity of the Company, including
     by way of merger, consolidation or otherwise.

     Executive's continued employment during the thirty (30) day period 
referred to above in this paragraph (d) shall not constitute Executive's 
consent to, or a waiver of rights with respect to, any act or failure to act 
constituting Good Reason hereunder.

          (e)  WITHOUT GOOD REASON OR CAUSE.  Executive shall have the right 
to terminate his employment hereunder without Good Reason and the Company 
shall have the right to terminate Executive's employment hereunder without 
Cause by providing the other with a Notice of Termination, and such 
termination shall not in and of itself be, nor shall it be deemed to be, a 
breach of this Agreement.

     6.   TERMINATION PROCEDURE.

          (a)  NOTICE OF TERMINATION.  Any termination of Executive's 
employment by the Company or by Executive during the Employment Period (other 
than termination pursuant to Section 5(a)) shall be communicated by written 
Notice of Termination (as defined below) to the other party hereto in 
accordance with Section 12 below.  For purposes of this Agreement, a "Notice 
of Termination" shall mean a notice which shall indicate the specific 
termination provision in this Agreement relied upon and shall set forth in 
reasonable detail the facts and circumstances claimed to provide a basis for 
termination of Executive's employment under the provision so indicated.

          (b)  DATE OF TERMINATION.  "Date of Termination" shall mean (i) if 
Executive's employment is terminated by his death, the date of his death, 
(ii) if Executive's employment is terminated pursuant to Section 5(b), thirty 
(30) days after Notice of Termination (provided that Executive shall not have 
returned to the substantial performance of his duties on a full-time basis 
during such thirty (30) day period) and (iii) if Executive's employment is 
terminated for any other reason, the date on which a Notice of Termination is 
given or any later date (within thirty (30) days after the giving of such 
notice) set forth in such Notice of Termination.

Executive is disabled or his employment terminates during the Employment 
Period, the Company shall provide Executive with the payments and benefits 
set forth below.  Executive acknowledges and agrees that the payments set 
forth in this Section 7 constitute liquidated damages for termination of his 
employment during the Employment Period.

          (a)  TERMINATION BY COMPANY WITHOUT CAUSE OR BY EXECUTIVE FOR GOOD 
REASON.  If Executive's employment is terminated by the Company without Cause

               (ii)  the Company shall reimburse Executive pursuant to Section
     4(d) for reasonable expenses incurred, but not paid prior to such

     8.   CONFIDENTIAL INFORMATION, OWNERSHIP OF DOCUMENTS; NON-COMPETITION.

          (a)  CONFIDENTIAL INFORMATION.  Executive shall hold in a fiduciary

which shall have been obtained by Executive during Executive's employment by 
the Company and which is not generally available public knowledge (other than 
by acts of Executive in violation of this Agreement).  Except as may be 
required or appropriate in connection with his carrying out his duties under 
this Agreement, Executive shall not, without the prior written consent of the 
Company or as may otherwise be required by law or any legal process, or as is 
necessary in connection with any adversarial proceeding against the Company 
(in which case Executive shall use his reasonable best efforts in cooperating 
with the Company in obtaining a protective order against disclosure by a 
court of competent jurisdiction), communicate or divulge any such 
Confidential Information relating to the Company to anyone other than the 
Company and those designated by the Company or on behalf of the Company in 
the furtherance of its business or to perform duties hereunder.

not include information that: (i) is already known to the recipient and was 
properly obtained by the recipient prior to the date of this Agreement; (ii) 
is in the public domain other than through a negligent act or omission or 
willful misconduct of the recipient; (iii) is acquired in good faith from a 
third party and, at the time of the acquisition, the recipient had no

or disclosed by the third party; (iv) is independently developed by the 
recipient from information not defined as "Confidential Information" in this 
Agreement, as evidenced by the recipient's written records; (v) is disclosed

to be disclosed under applicable law or by a valid subpoena or other court or 
governmental order, decree, regulation or rule; PROVIDED, HOWEVER, that if 
disclosure is required under this provision the recipient shall advise the 
disclosing party of the requirement to disclose the Confidential Information 
prior to such disclosure and as soon as reasonably practicable after the 
recipient becomes aware of such required disclosure; and FURTHER PROVIDED 
THAT upon the request of the disclosing party, the recipient agrees to 
cooperate in good faith with any reasonable and lawful actions which the 
disclosing party takes to resist such disclosure, limit the information to be 
disclosed or limit the extent to which the information so disclosed may be 
used or made available to third parties, at the cost of the disclosing party.

          (b)  REMOVAL OF DOCUMENTS; RIGHTS TO PRODUCTS.  All records, files, 
drawings, documents, models, equipment, and the like relating to the 
Company's business, which Executive has control over shall not be removed 
from the Company's premises by Executive without the Board's written consent, 
unless such removal is in the furtherance of the Company's business or is in 
connection with Executive's carrying out his duties under this Agreement and, 
if so removed by Executive, shall be returned to the Company promptly after 
termination of Executive's employment hereunder, or otherwise promptly after 
removal if such removal occurs following termination of employment.  
Executive shall assign to the Company all rights to trade secrets and other 
products relating to the Company's business developed by him alone or in 
conjunction with others at any time while employed by the Company.

          (c)  CONTINUING OPERATION.  Except as specifically provided in this 
Section 8, the termination of Executive's employment or of this Agreement 
shall have no effect on the continuing operation of this Section 8.

     9.   INDEMNIFICATION.  Upon the Commencement Date, Executive will enter 
into the Company's standard directors and officers indemnification agreement.

     10.  ARBITRATION.  Any controversy between Executive and the Company 
involving the construction or application of any of the terms, provisions or 
conditions of this Agreement, including, without limitation, the 
determination of whether "Cause" or "Good Reason" exists under Section 5(c) 
or Section 5(d) hereof and claims involving specific performance, shall on 
the written request of either party served on the other in accordance with 
Section 12 below be submitted to binding arbitration.  EACH PARTY, BY SIGNING 
THIS AGREEMENT, VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVES ANY RIGHTS 
SUCH PARTY MAY OTHERWISE HAVE TO SEEK REMEDIES IN COURT OR OTHER FORUMS, 
INCLUDING THE RIGHT TO A JURY TRIAL. Arbitration shall comply with and be 
governed in accordance with the Commercial Arbitration Rules of the American 
Arbitration Association (the "AAA").  The arbitration will be conducted only 
in Denver, Colorado, before a single arbitrator selected by the parties or, 
if they are unable to agree on an arbitrator, before an arbitrator selected 
by the AAA.  The arbitrator shall have full authority to order specific 
performance and award damages and other relief available under this Agreement 
or applicable law, but shall have no authority to add to, detract from, 
change or amend the terms of this Agreement or existing law.  All arbitration 
proceedings, including settlements and awards, shall be 



                                      8
<PAGE>

confidential.  The decision of the arbitrator will be final and binding, and 
judgment on the award by the arbitrator may be entered in any court of 
competent jurisdiction.  THIS SUBMISSION AND AGREEMENT TO ARBITRATE WILL BE 
SPECIFICALLY ENFORCEABLE.  The arbitrator will have no power to award 
punitive or exemplary damages, to ignore or vary the terms of this Agreement 
and any other agreement between Executive and the Company and will be bound 
to apply controlling law. The prevailing party in any such arbitration shall 
be entitled to receive the costs of arbitration, including reasonable 
attorneys' fees and costs, from the losing party.

     11.  SUCCESSORS; BINDING AGREEMENT.

          (a)  COMPANY'S SUCCESSORS.  No rights or obligations of the Company 
under this Agreement may be assigned or transferred, except that the Company 
will require any successor (whether direct or indirect, by purchase, merger, 
consolidation or otherwise) to all or substantially all of the business 
and/or assets of the Company to expressly assume and agree to perform this 
Agreement in the same manner and to the same extent that the Company would be 
required to perform it if no such succession had taken place.  As used in 
this Agreement, "Company" shall mean the Company as herein before defined and 
any successor to its business and/or assets (by merger, purchase or 
otherwise) which executes and delivers the agreement provided for in this 
Section 11 or which otherwise becomes bound by all the terms and provisions 
of this Agreement by operation of law.

          (b)  EXECUTIVE'S SUCCESSORS.  No rights or obligations of Executive 
under this Agreement may be assigned or transferred by Executive other than 
his rights to payments or benefits hereunder, which may be transferred only 
by will or the laws of descent and distribution. Upon Executive's death, this 
Agreement and all rights of Executive hereunder shall inure to the benefit of 
and be enforceable by Executive's beneficiary or beneficiaries, personal or 
legal representatives or estate, to the extent any such person succeeds to 
Executive's interests under this Agreement.  Executive shall be entitled to 
select and change a beneficiary or beneficiaries to receive any benefit or 
compensation payable hereunder following Executive's death by giving the 
Company written notice thereof.  In the event of Executive's death or a 
judicial determination of his incompetence, reference in this Agreement to 
Executive shall be deemed, where appropriate, to refer to his 
beneficiary(ies), estate or other legal representative(s).  If Executive 
should die following his Date of Termination while any amounts would still be 
payable to him hereunder if he had continued to live, all such amounts unless 
otherwise provided herein shall be paid in accordance with the terms of this 
Agreement to such person or persons so appointed in writing by Executive, or 
otherwise to his legal representatives or estate.
