          these monthly payments to Mr. Falcao on or before the last day of the
          respective month. The maximum Mr. Falcao can receive under this
          paragraph is One Hundred Sixty Five Thousand Dollars ($165,000.00),

a change of control event where the acquiror is one of the entities named in (b)
above, the obligations contained in the preceding sentence shall expire one year
after the effective date of this Agreement or, if later, upon the consummation
of such change of control event.. The parties further agree that in the event
the Company experiences a change of control event where the acquiror is an
entity not named in (b) above, the obligations contained in the second sentence
of this paragraph shall expire six months after consummation of such change of
control event. Change of control event shall mean the sale by the Company of
shares representing more than 50% of the voting power of the Company or a change
in the identity of a majority of the directors of the Company due to (i) a proxy
contest or (ii) any unsolicited tender, exchange or other purchase offer.

      13. It is the intention of the Parties that this Agreement shall be
enforceable to the fullest extent allowed by law. In the event that a court
holds any provision of this Agreement to be unenforceable, the Parties

                                      -6-
<PAGE>

agree that, if allowed by law, that provision shall be reduced to the degree
necessary to render it enforceable without affecting the rest of this Agreement,
and, if such reduction is not allowed by law, the Parties shall promptly agree
in writing to a provision to be substituted therefore which will have an effect
as close as possible to the invalid provision that is consistent with applicable
law. The Parties agree that the invalidity or unenforceability of any provision
of this Agreement shall not affect or limit the validity and enforceability of
the other provisions hereof.

      14. The Parties agree that any breach by Mr. Falcao of any of the
provisions contained in paragraph 12 of this Agreement will cause the Company
immediate, material and irreparable injury and damage, and there is no adequate
remedy at law for such breach. Accordingly, in the event of a breach of any of
the provisions of this Agreement by Mr. Falcao, in addition to any other
remedies it may have at law or in equity, the Company shall be entitled
immediately to seek enforcement of this Agreement in a court of competent
jurisdiction by means of a decree of specific performance, an injunction without
the posting of a bond or the requirement of any other guarantee, any other form
of equitable relief, liquidated damages in the amount of $10 million in the
event the breach involves any company named in clause (b) of paragraph 12, and
the Company is entitled to recover from Mr. Falcao the costs and attorneys' fees
it incurs to recover under or enforce this Agreement. This provision is not a
waiver of any other rights which the Company may have under this Agreement,
including the right to receive money damages.

      15. Mr. Falcao acknowledges and agrees that the covenants contained herein
are necessary for the protection of the Company's legitimate business interests
and are reasonable in scope and content. The Parties agree that the failure of
the Company to enforce any term of this Agreement (or any agreement with any
other person) shall not constitute a waiver of the Company's rights or deprive
the Company of the right to insist thereafter upon strict adherence to that or
any other term of this Agreement, nor shall a waiver by the Company of any
breach of this Agreement constitute a waiver of any preceding or succeeding
breach, nor shall the passage of any amount of time after the Company becomes
aware of a breach of this Agreement constitute a waiver of its rights to
enforcement. No waiver of a right under this Agreement shall be binding on the
Company unless expressly made in writing and signed by the President of the
Company.

      16. Mr. Falcao agrees that the above-mentioned consideration is not to be
construed as an admission of any wrongdoing or liability on the part of the
Company under any statute or otherwise, but that on the contrary, any such
wrongdoing or liability is expressly denied by the Parties.

      17. Mr. Falcao agrees that neither this Agreement nor the negotiations in
pursuance thereof shall be construed or interpreted to render Mr. Falcao a
prevailing party for any reason, including but not limited to an award of
attorney's fees, expenses or costs under any statute or otherwise.

      18. Mr. Falcao represents that he has not heretofore assigned or
transferred, or purported to assign or transfer, to any person or entity, any
claim against the Company or portion thereof or interest therein, and that any
such claim is not assignable or transferable.

      19. The Parties agree that this Agreement shall be binding upon and inure
to the benefit of the personal representatives, heirs, executors, and
administrators of Mr. Falcao and the heirs, executors, administrators,
affiliates, successors, predecessors, subsidiaries, divisions, officers,
purchasers, agents, assigns, representatives, directors and employees of the
Company.

      20. Mr. Falcao acknowledges, represents and agrees that he continues to be
bound by the Secured Promissory Note dated August 11, 1999 in the amount of One
Million Two Hundred and Twenty-Four Thousand Dollars ($1,224,000.00) (herein
"August 11, 1999 Secured Promissory Note") which is attached hereto as Exhibit 4
and incorporated by reference. Mr. Falcao agrees to execute and be bound by the
Proprietary Information and Inventions Agreement (herein "October 2, 2000
Proprietary Information and Inventions Agreement") that is attached hereto as

      21. The Parties agree that this Agreement, Paragraph 6 of the July 22,
1999 Employment Agreement which is attached hereto as Exhibit 3, the October __
2000 Amended Lock-Up Agreement which is attached hereto as Exhibit 1, the August
11, 1999 Secured Promissory Note which is attached hereto as Exhibit 4, and the
October 2, 2000 Proprietary Information and Inventions Agreement which is
attached hereto as Exhibit 5, contain and comprise the entire agreement and
understanding of the Parties, that there are no additional promises or terms
between the Parties, and all other discussions, promises, representations, and
understandings relating to the topics herein discussed are hereby merged into
this Agreement. This Agreement may be modified only by a written instrument
signed by Mr. Falcao and the President and Chief Executive Officer of the
Company.

      22. The Parties agree that this Agreement and the rights and obligations
hereunder shall be governed by, and construed in accordance with, the laws of
the State of Maryland regardless of any principles of

                                      -8-
<PAGE>

conflicts of laws or choice of laws of any jurisdiction. The Parties agree that
the state courts of the State of Maryland and, if the jurisdictional
prerequisites exist, the United States District Court for the District of
Maryland, shall have sole and exclusive jurisdiction and venue to hear and
determine any dispute or controversy arising under or concerning this Agreement.

      23. If any terms of the above provisions of this Agreement are found null,
void or inoperative, for any reason, the remaining provisions will remain in
full force and effect. The language of all parts of this Agreement shall in all
cases be construed as a whole, according to its fair meaning, and not strictly
for or against either of the Parties.

      24. Mr. Falcao represents that he has read this Agreement, that he
understands all of its terms, that in executing this Agreement he does not rely
and has not relied upon any representation or statements made by any of the
Company's agents, representatives, or attorneys with regard to the subject
matter, basis, or effect of the Agreement, and that he enters into this
Agreement voluntarily, of his own free will, without any duress and with
knowledge of its meaning and effect.

      25. Mr. Falcao understands that he has twenty-one (21) days from the date
of his receipt of this Agreement, which was September 28, 2000, to consider his
decision to sign it, and that he may unilaterally waive this period at his
election. Mr. Falcao's signature on this Agreement constitutes an express waiver
of the twenty-one (21) day period if affixed prior to the expiration of that
period. By signing this Agreement, Mr. Falcao expressly acknowledges that his
decision to sign this Agreement was knowing and voluntary and of his own free
will. Mr. Falcao understands that he is not waiving any claims that may arise
after the date of this Agreement.

      26. Mr. Falcao acknowledges that he may revoke this Agreement only as it
pertains to claims under the ADEA for up to and including seven (7) days after
his execution of this Agreement, and that the aspects of this Agreement
regarding his release of claims under the ADEA shall not become effective until
the expiration of seven (7) days from the date of his execution of this
Agreement. This provision as of this Agreement are independently supported by
adequate consideration and are fully enforceable. Mr. Falcao expressly agrees
that, in order to be effective, his revocation pursuant to this Paragraph must
be in writing and must actually be received by Kim Larsen, Senior Vice President
and General Counsel of Corvis, before 5:00 p.m. on the seventh day following Mr.
Falcao's execution of this Agreement.

directors, officers and their agents and representatives, in each case acting
under specific directions, to refrain from uttering or publishing to any third
party by oral, written or electronic statements or comments any derogatory
remarks which disparage or defame the business or personal reputation of the
