FOR IMMEDIATE RELEASE CIENA ANNOUNCES MUTUAL TERMINATION OF PROPOSED MERGER WITH TELLABS LINTHICUM, MD - SEPTEMBER 14, 1998 - CIENA Corporation (NASDAQ: CIEN) today announced that it has agreed to a mutual termination of its planned merger with Tellabs. The companies believe that investor reaction to events of the last several weeks raised serious questions about the ultimate ability to obtain shareholder approval for the merger and made it difficult to move forward with the kind of momentum needed to realize shareholder value. Therefore, the companies have agreed to part ways amicably. The terms of the merger termination do not trigger break-up fees for either company. "While we are disappointed that our plans with Tellabs will not come to fruition, we remain excited about our future as an independent entity," said Patrick Nettles, CIENA's President and Chief Executive Officer. Nettles continued: "Over the short-term, CIENA will continue to face the challenges associated with expanding our customer base, but the core elements of our business remain strong: - - Our market opportunity is large and growing as more carriers turn to the economies and network scalability offered by DWDM and as we identify and pursue new applications beyond long-distance transport; - - CIENA's technology leadership is evident - we are the only DWDM vendor commercially shipping a 40-channel system with more than one million channel 2 kilometers installed for customers on three continents - and we will work aggressively to leverage and expand on that leadership position; - - Our team's spirit is indomitable; - - The balance sheet is strong with over $200 million in cash, and: - - We continue to grow our base of satisfied customers." # # # Additional information about CIENA can be found on its World Wide Website: http://www.ciena.com.

FOR IMMEDIATE RELEASE CIENA Reports Final Fiscal Third Quarter Results; Issues Cautious Short-Term Outlook LINTHICUM, MD - SEPTEMBER 14, 1998 - CIENA Corporation (NASDAQ: CIEN) today reported final results for its third fiscal quarter ended August 1, 1998, in-line with its previously announced expectations. Revenue for the quarter totaled $129.1 million. This compares with $121.8 million in revenue reported for the third fiscal quarter of 1997. Net income for the quarter was $16.1 million, or $0.15 per share, exclusive of one-time charges associated with CIENA's previously announced settlement with Pirelli and costs related to the proposed merger with Tellabs. This compares with net income for the third fiscal quarter of 1997 of $35.7 million, or $0.34 cents per share.(1) For the nine months ended August 1, 1998, revenue increased to $416.9 million from $283.1 million for the first nine months of 1997. Net income for the period was $86.8 million, or $0.81 per share, compared to $81.1 million, or $0.78 per share, for the same period in 1997, once again, excluding the effect of one-time charges for purchased research and development and merger costs in 1998 and additional expense accruals pertaining to the Company's litigation with Pirelli in both 1997 and 1998.(1) Net income and earnings per share amounts reported in the attached consolidated statement of operations are inclusive of the effects of one-time charges and litigation 2 expenses. All earnings per share amounts represent diluted earnings per share as defined within Statement of Financial Accounting Standards No. 128 (SFAS 128). "As we discussed previously, CIENA's gross margins during the third fiscal quarter were impacted by the combination of price concessions to a strategic customer in return for higher volume commitments, and lower than expected overall volume during the quarter," said CIENA's Senior Vice President, Finance and Chief Financial Officer, Joseph Chinnici. "In light of continued evidence that our (more) 3 competitors are heavily discounting their prices in an attempt to gain a market presence, we're adjusting our long-term gross margin target model range to 45 to 50 percent." "During the last year CIENA grew its manufacturing infrastructure to accommodate a higher level of business than we will realize in the near-term; as a result it is likely that unabsorbed manufacturing overhead will pull gross margins below the target model short-term," continued Chinnici. "Provided volumes increase as we progress through fiscal 1999 as we currently expect, unabsorbed manufacturing overhead will diminish in significance. We also expect to continue our focus on lowering material costs and reducing the costs in our products through ongoing engineering efforts in order to partially mitigate the potential negative impact of pricing pressure on gross margins." CIENA continued to make positive progress toward its goal of diversifying both its product and customer base during the quarter, announcing and shipping to a total of 11 customers including two new customers: Telecom Developpment and Racal; both of which are expected to contribute to revenue during fiscal year 1999. Commenting on his expectations for CIENA's fiscal fourth quarter and fiscal year 1999, Patrick Nettles, CIENA's President and Chief Executive Officer, said: "Feedback received from our sales force indicates that the uncertainty created by the events of the last few weeks and attempts of our competitors to capitalize on that uncertainty may delay or alter some customers' near-term purchase decisions. As a result, and due to the loss of expected incremental business at DTI, we believe fiscal fourth quarter revenues and operating results will be materially below those reported for the third fiscal quarter. In addition, while visibility is, as always, very limited beyond the next quarter, we are now resetting our fiscal 1999 business model at a level that anticipates modest growth in year-over-year revenue and net income." "Going forward, we intend to restore shareholder value as quickly as possible by: 1) continuing our proven record of rapid product introduction and technology innovation that enables our customers to simplify their networks and lower the cost of bandwidth; 2) driving down costs in our products to help us achieve and maintain solid margins, and; 3) bolstering our sales and marketing efforts," said Nettles. 4 In a separate press release made today, CIENA announced it has restructured its sales and marketing organization to better address the rapidly evolving DWDM market opportunity and the company's growing customer base. (more) 5 "There is no doubt that the next several quarters will be challenging for CIENA as we work to rebuild shareholder value," said Jon Bayless, CIENA's Chairman of the Board. "The company has recently experienced first-hand a number of the risks we've regularly discussed as being inherent in growing a dynamic business in an industry dominated by large competitors. CIENA's Board of Directors has complete confidence that CIENA's management team will restore positive momentum and lead this company through the challenges it faces during its next important phase of development." In conclusion Nettles said: "As an emerging company, CIENA has battled the underdog status for most of its corporate life. As a team, our employees have faced and conquered enormous hurdles and their spirit is unyielding. Ultimately, it is these highly motivated people, our field-proven products, and our industry-leading technology that will enable us to capitalize on the opportunities ahead." (1) Past financial results have been restated to reflect the consolidated results of Alta Telecom, Inc., acquired by CIENA on February 19, 1998. NOTE TO INVESTORS: Forward-looking statements in this release, including statements regarding (1) the anticipation that fiscal fourth quarter revenues and operating results will be materially below those reported for the third fiscal quarter and that net income also will likely be significantly lower and, (2) the setting of the fiscal 1999 business model to a level that shows modest year-over-year revenue and net income growth, are based on information available to the Company as of the date hereof. The Company's actual results could differ materially from those stated or implied by such forward-looking statements, due to risks and uncertainties associated with the Company's business. The forward-looking statements should be considered in the context of these and other risk factors disclosed in the Company's Quarterly Report on Form 10-Q, as filed with the Securities and Exchange Commission on September 14, 1998.

FOR IMMEDIATE RELEASE CIENA INTRODUCES OC-192 CAPABILITY FOR MULTIWAVE SENTRY(TM) DWDM SYSTEM ALLOWS CARRIERS TO SCALE FIBER CAPACITY TO ONE TERABIT LINTHICUM, MD - SEPTEMBER 14, 1998 - CIENA Corporation (NASDAQ: CIEN) announced today the introduction of an OC-192/STM 64 (10 Gb/s) interface to its scalable MultiWave Sentry dense wavelength division multiplexing (DWDM) system. The enhancement to Sentry's system will enable service providers to increase the capacity of a single strand of fiber carrying 100 gigabits per second (Gb/s) today to 480 Gb/s by early 1999 and approaching one terabit by the year 2000. "The addition of the OC-192 interface to MultiWave Sentry provides CIENA's customers with another feature enabling future network flexibility while protecting existing network investments," said Steve Chaddick, CIENA's senior vice president of products and technologies. "The OC-192 interface offers carriers another alternative in the race to keep pace with rapidly increasing growth in high-speed data services and new options for creating data-centric network architectures such as IP/ATM over DWDM." CIENA's enhanced MultiWave Sentry is suitable for service providers' long-haul, dense route applications that require scalable capacity. This new capability makes it possible for carriers to simultaneously mix or match up to forty-eight 10 Gb/s (OC-192/OC-192c/STM-64) SONET or SDH channels with 2.5 Gb/s (OC-48/OC-48c/STM-16) channels thereby 2 protecting current network investments while giving them increased options for bandwidth and network scalability. MultiWave Sentry includes CIENA's open architecture and DirectConnect feature that make it feasible for carriers to mix SONET/SDH, ATM and IP traffic on a common optical network. This simplifies the network architecture and eliminates the additional cost associated with an intervening synchronous layer in evolving data-centric ATM and IP networks. The addition of the OC-192 interface will support the next generation of high-speed routers and switches with the 10 Gb/s interface.

FOR IMMEDIATE RELEASE CIENA BOLSTERS STRATEGY, MARKETING AND SALES FUNCTIONS LINTHICUM, MD - SEPTEMBER 14, 1998 - CIENA Corporation (NASDAQ: CIEN) today announced that it has created a new strategy and marketing organization and realigned its sales organization to better address the rapidly evolving optical networking market opportunity and the company's growing customer base. Steve Chaddick, formerly CIENA's Senior Vice President of Products and Technologies will become Senior Vice President, Strategy and Corporate Development, responsible for creating CIENA's marketing programs and strategic vision and for building corporate alliances. He will report to President and Chief Executive Officer, Patrick Nettles. Jesus Leon, currently Vice President, Product Development, will assume Chaddick's previous responsibilities. Daniel McCurdy, formerly Vice President, Corporate Development, will become CIENA's Vice President, Marketing and Strategic Transactions, reporting to Chaddick. CIENA's marketing communications functions also will report to McCurdy. "In our early stages, CIENA effectively mixed the functions of sales and marketing," said Nettles. "As we've grown and as competition has become more vocal, it has become clear that we need to devote dedicated efforts solely toward defining, articulating and executing our strategic vision." Nettles continued, "Steve Chaddick has been instrumental in shaping CIENA's product direction and we are pleased he has agreed to drive those continued 2 efforts in a formal capacity. We also are pleased that Dan McCurdy has agreed to expand his responsibilities, making use of his extensive marketing experience." Huang, previously CIENA's Senior Vice President, Sales and Marketing will become Senior Vice President, Strategic Account Sales reporting to Nettles. Gary B. Smith, formerly Vice President, International Sales will assume responsibility for all other worldwide sales, also reporting to Nettles. (more) "In the last year CIENA has grown its customer base from just two to more than thirteen customers and Larry Huang has been a driving force behind that successful customer diversification," commented Nettles. "As long as CIENA remains dependent on a few key customers, however, strategic account management is critical. In his new capacity, Larry will be able to apply his energies specifically to CIENA's key customers." Said Nettles of Smith, "Since joining CIENA in November 1997, Gary Smith has significantly increased CIENA's presence in emerging international markets growing the international contribution to revenue from less than 10 percent to approximately 25 percent in the most recent quarter. We expect he will have the same kind of success leading our efforts to expand CIENA's customer base in his new capacity as Vice President, Global Sales." "CIENA is a young company that has been forced to grow up quickly," concluded Nettles. "We believe these changes in the organization of our senior management will enable us to more effectively grow our business to the next level." # # # ABOUT CIENA Based in Linthicum, Maryland, CIENA Corporation is a worldwide market leader of open architecture, dense wavelength division multiplexing (DWDM) systems for long-distance and local exchange carriers.

FOR IMMEDIATE RELEASE CIENA CEO STATEMENT ON TODAY'S EVENTS LINTHICUM, MD - SEPTEMBER 14, 1998 - The following can be attributed to Patrick Nettles, president and CEO, CIENA Corporation: "Today, CIENA is taking a series of steps geared to demonstrate our commitment to the company's original mission established four and a half years ago: simplifying the network and lowering the cost of bandwidth for our customers." "Four months ago, we announced our intent to merge with Tellabs as a means to expand the scope of that mission. While the strategic basis for this transaction still remains compelling, our short-term financial performance and the effect of recent events to our near-term outlook, has made it highly improbable that we can get shareholder approval without substantially undervaluing CIENA." "Demonstrating our commitment to move forward, CIENA also announced today an organizational restructuring that will strengthen our sales and marketing so we can focus on our customers, take advantage of new business opportunities and increase shareholder value." "In addition, we unveiled a new product capability today that illustrates CIENA's ability to deliver new capabilities to the market that further define us as the world's leader in optical networking." 2 "After all is said and done, CIENA remains a young, vibrant and high growth potential company with a strong balance sheet, a strong workforce that is charged up and a strong growing base of satisfied customers."

FOR IMMEDIATE RELEASE CIENA ANNOUNCES SUMMARY JUDGEMENT GRANTED IN ITS FAVOR IN KIMBERLIN CASE LINTHICUM, MD - SEPTEMBER 14, 1998 - A federal district court has dismissed federal securities law claims brought against CIENA Corporation (NASDAQ: CIEN) and certain of its individual directors by investor Kevin Kimberlin and related parties, finding "no violations" of federal securities laws in the Company's or directors' conduct. Kimberlin filed the lawsuit in November 1996 in the U.S. District Court for the Southern District of New York against the company and certain directors, alleging that Kimberlin and other parties controlled by him had been fraudulently denied the opportunity to purchase shares in CIENA in connection with a private offering in December 1995. In a decision dated September 9, 1998, but received by the Company today following its morning conference call with financial analysts, U.S. District Court Judge Sonia Sotomayor granted CIENA's motion for summary judgement as to the Kimberlin plaintiffs' federal securities claims, finding "no violations of the federal securities laws in [CIENA's and the individually-named board members'] conduct." The Court also dismissed all related state law claims without prejudice, declining to exercise jurisdiction over these claims. Patrick Nettles, CIENA's President and Chief Executive Officer said, "We are delighted that the court has agreed with our position that there was no basis for these claims, and 2 we are pleased that we can put this distraction behind us and move forward with our business." ### ABOUT CIENA Based in Linthicum, Maryland, CIENA Corporation is a worldwide market leader of open architecture, dense wavelength division multiplexing (DWDM) systems for long-distance and local exchange carriers.
